Description

A power line jumper

technical field

The invention relates to a power line jumper.

Background technique

In the maintenance work of transmission lines, the work of replacing and removing the ground wire is often encountered. How to deal with and protect the power line of 10KV and above in the work is often a core issue. In the past construction, it is often used The following centralized processing methods:

Line Loosening Method: Before the construction of the upper span (the line to be laid or replaced), loosen the lower span (the line that needs to be crossed under the laid or replaced line) to the ground, and restore the lower span after the construction of the upper span is completed line. This method is safe and reliable, but it needs to coordinate the owner or management unit of the cross-line, and the implementability is low.

Spanning frame method: build a spanning frame at the lower span point, and the spanning frame is divided into a single-sided spanning frame and a closed spanning frame (the closed spanning frame is mostly used for live spanning construction). This method is relatively stable when the line continues to cross the line. It is only suitable for the cross-line construction of long lines or large-scale lines. However, the erection process is complicated and requires climbing operations. The impact on the height of the ground has great limitations, and the construction is time-consuming and expensive.

Ring method: use rings and ropes at the crossing point to use the method of hanging the wire (the wire hangs the ground wire, the ground wire hangs the wire, and the wire hangs the wire) to keep the ground wire away from the line under the span, so as to play a protective role. This method is similar to the spanning method, requiring the erection of a suspension wire device, and the operation is relatively cumbersome, and this method requires a person to ascend the height and insert the upper span wire into the suspension ring to take up and lead the wire, which is not only cumbersome to operate but also has the danger of climbing.

At present, the power supply for residents in cities is basically replaced by underground pipelines instead of traditional overhead lines, but overhead lines are still used in urban-rural fringe areas and rural areas. During the erection of new lines and the reconstruction of old lines in the urban-rural fringe areas and rural areas, the problem of cross-line (existing line) erection is generally encountered. Since there are many types of crossover lines in the urban-rural fringe area and rural areas, such as mains power supply lines, telephone lines, radio and television broadcasting lines, broadband Internet access lines, etc., if the above-mentioned loosening method is used, it will require the cooperation of multiple departments, which is very difficult , The construction period is long, and the implementability is extremely small; If the above-mentioned spanning frame method or the suspension ring method is adopted, there are still disadvantages that a spanning frame or a hanging wire device needs to be erected, the operation is cumbersome, and the construction is time-consuming and expensive.

Contents of the invention

The present invention aims at the above-mentioned deficiencies, and proposes a kind of electric power straddle jumper with reasonable structure, small volume, fast assembly or erection, capable of completing the functions of crossing, picking up and leading wires on the ground, simple operation, no need to climb high, and high safety. device.

In order to solve the above problems, the structural features of this power line jumper are: it includes a base fixed to the upper end of the insulating rod, the upper part of the base is provided with a base groove that runs through the front and rear ends of the base, and a bottom wheel for supporting cables is installed in the base groove , the side of the base is hinged with an upper cover that can be fastened to the upper end of the base through a hinge shaft. The upper cover is provided with an upper cover groove corresponding to the base groove, and an auxiliary wheel is installed in the upper cover groove through an adjustment device. The adjustment device can adjust the auxiliary wheel. The depth of the wheel in the groove of the upper cover, the outer circumference of the bottom wheel and the auxiliary wheel is provided with a ring groove that matches the cable, the outer wall of the base below the hinge shaft is fixed with a support rod, the end of the support rod is hinged with a transmission rod, and the upper end of the transmission rod is hinged There is an upper connecting rod, the upper end of the upper connecting rod is hinged with the outer wall of the upper cover above the hinge shaft, the upper sliding sleeve of the lower part of the transmission rod is equipped with an upper sliding sleeve, and the middle part of the upper sliding sleeve is hinged with an insulating rod extending downward along the insulating rod. The rod is fixed with a middle sliding sleeve that slides axially with the insulating rod, the upper part of the insulating rod is provided with a swing chamber that cooperates with the lower part of the transmission rod, and the lower part of the insulating rod is provided with an operating part that drives the insulating rod to move axially.

This power line straddling device can be quickly assembled or erected through an adjustable clamping rolling support structure. It can complete the functions of crossing, picking up and leading wires on the ground. It is easy to operate, does not need to climb high, and has high safety.

The adjustable clamping rolling support structure mainly includes a base supported by insulating rods and an upper cover hinged on the base. The upper cover can rotate around the hinge axis to realize the function of being fastened on the base or lifted from the base. The base is provided with a base groove, the base groove extends horizontally and runs through both ends of the base, and the base groove mainly provides passing space for passing cables. For the convenience of description, in the horizontal plane, the directions of the two ends through which the base groove penetrates are respectively called front and rear, and the connecting direction is called longitudinal direction, and the directions on both sides of the base groove are called left and right, respectively, and the connecting direction is called Transversely, the direction perpendicular to the horizontal plane is referred to as the vertical or vertical direction. A bottom wheel is installed in the base groove, and the axis line of the bottom wheel rotating shaft is arranged horizontally. The rollers will play the role of rolling support for the passing cables, reducing the passing friction, improving the passing smoothness and ensuring the integrity of the cable skin. The upper cover is also provided with an upper cover groove corresponding to the base groove, and the upper cover groove is also provided through two ends of the upper cover. When the upper cover is fastened on the base, the upper cover groove and the base groove will be connected up and down as a whole. For the convenience of description, the cavity or through groove that connects the upper cover groove and the base groove up and down is called "transfer groove" or "full groove", and the state where the upper cover and the base are fastened together is called the buckled state or closed state. State, the state that the upper cover is lifted from the base is called the lifted state or the open state. An auxiliary wheel is arranged in the slot of the upper cover, and the auxiliary wheel is installed on the upper cover through the adjustment device. The axis line of the rotating shaft of the auxiliary wheel is also extended from left to right or arranged laterally, so that in the buckled state, the rotating shaft of the auxiliary wheel is arranged parallel to the rotating shaft of the bottom wheel. Because the outer circumference of the bottom wheel and the auxiliary wheel is provided with a ring groove that matches the cable, a similar circular gap or cavity will be formed between the auxiliary wheel and the bottom wheel in the fastened state, and this gap or cavity is the transmission The cavity through which the cable passes. For the convenience of description, this cavity is called "transmission cavity" or "cable cavity". The main function of the adjusting device is to adjust the depth of the auxiliary wheel in the groove of the upper cover, that is, to adjust the distance between the auxiliary wheel and the bottom wheel in the buckled state, that is, to adjust the size or thickness of the transmission cavity. When the transmission cavity is thicker than the upper jumper cable, the rolling cooperation of the cable with the bottom wheel and the auxiliary wheel makes the cable smoothly transmitted in the transmission cavity. For convenience of description, this cooperative state of auxiliary wheel and bottom wheel is called " transmission state " or " smooth state ".

In the power line jumper, a support rod is also fixed on the base, and the support rod is located below the connecting hinge shaft between the upper cover and the base. A drive rod is hinged at the end of the support rod, and an upper link is hinged at the upper end of the drive rod, and the upper end of the upper link is hinged with the upper rod part above the hinge shaft correspondingly. Because the hinges on which the upper connecting rod and the transmission rod are hinged are generally arranged parallel to the hinge shaft between the upper cover and the base, rather than vertically, so when the lower end of the transmission rod is swung up and down, the upper end of the transmission rod It will also drive the lower end of the upper link to swing up and down, and because the support rod and the hinge shaft are relatively fixed, the up and down swing of the lower end of the upper link can only be driven by the upper end of the upper link to swing the upper cover around the hinge axis. The fastening or opening of the drive loam cake has just been realized. The upper sliding sleeve of the lower part of the transmission rod has an upper sliding sleeve, and the upper sliding sleeve is hinged with an insulating rod extending vertically downward. Actions are limited to sliding up and down only. The lower end of the insulating rod is provided with an operating part, which can be conveniently driven to move the insulating rod up and down by moving the operating part. At this time, the upper sliding sleeve at the upper end of the insulating rod will divide the force of the insulating rod sliding up and down into the force driving the lower part of the transmission rod to move up and down. And the force that makes the upper sliding sleeve slide up and down along the transmission rod, so that the upper cover can be driven by the transmission of the transmission rod and the upper connecting rod to complete the fastening or opening action. In detail, when the insulating rod is driven upward by the operating part on the ground, the upper end of the insulating rod will drive the lower end of the transmission rod to move up and the upper end of the transmission rod will move down. At this time, the upper end of the transmission rod will move the upper cover from the base through the upper link. Pull up, just finished the loam cake on the control insulation bar top on the ground and open or uncap action. Conversely, when the insulating rod is driven down by the operating member, the support rod will drive the upper cover to snap onto the base through the upper connecting rod, thus completing the upper cover buckling or buckling action on the ground to control the insulating rod. For the convenience of description, all transmission mechanisms that control the upper cover above the insulating rod on the ground to open or buckle the cover are called remote control mechanisms.

When the remote control mechanism cooperates with the adjustment device, three functions can be realized: fixedly clamping the upper jumper cable head and crossing from one side of the lower jumper cable to the other side of the lower jumper cable (jumping or jumping), Fix and hold the upper jumper cable head and guide it forward, pull the upper jumper cable (lead wire), lift the upper jumper cable above the lower jumper and maintain a smooth and stable lifting relationship with the upper jumper cable (pick the thread).

By operating the regulating device, the thickness of the transmission cavity can be controlled. When the transmission cavity is thicker than the upper jumper cable, the rolling cooperation of the cable with the bottom wheel and the auxiliary wheel makes the cable smoothly transmitted in the transmission cavity. In detail, when the cable needs to be smoothly transmitted in the transmission chamber, the upper cover and the base are switched to the buckled state, and the auxiliary wheel is adjusted upward through the adjustment device, that is, the direction of the bottom of the upper cover groove is adjusted. At this time, the transmission chamber is horizontal. The section becomes larger and thicker than the conveying cable. When the cable is conveyed in the cable cavity, due to the gravity of the cable, generally only the bottom wheel will roll and support and limit the lower part of the cable and the two sides of the lower part through its ring groove. Only when the cable shakes upwards and leaves the bottom wheel, the auxiliary wheel The upper part of the cable and the two sides of the upper part will be supported and limited by rolling through its ring groove. Therefore, the surroundings of the cable will be supported and limited by the "elastic" rolling support and rolling position of the auxiliary wheel and the bottom wheel. The movement of the cable in the transmission cavity The range of motion is relatively large, so that the cables can move smoothly in the transmission cavity, and the cables in the transmission cavity can be raised or lowered freely through the base and the upper cover without affecting the transmission speed and skin integrity of the cables. The transmission state is suitable for rapid transmission of the rolling support cable when the upper jumper cable has crossed the lower jumper and the upper jumper has been inserted into the transfer cavity. For convenience of description, this cooperative state of auxiliary wheel and bottom wheel is called " transmission state " or " smooth state ".

When the transmission cavity is thinner than the upper jumper cable, driven by the remote control mechanism, the upper cover is pressed tightly on the base, and the auxiliary wheel and the bottom wheel clamp the upper jumper cable. At this time, the upper jumper cable is relatively fixed on the inside the transmission chamber. In detail, operating the adjusting device will move the auxiliary wheel in the buckled state downward, that is, the auxiliary wheel will be lifted from the bottom of the upper cover groove, at this time, the distance between the auxiliary wheel and the bottom wheel will be reduced, and the transmission cavity will become larger than the cable to be transported. That is, the upper jumper cable should be thinner. In this way, in the buckled state, the auxiliary wheel and the bottom wheel will produce an up and down "clamping force" on the upper jumper cable to clamp the upper jumper cable into the transmission cavity, and the upper jumper cable is relatively fixed on the base and the upper rod. At the same time, at this time, the clamped upper jumper cable head can be spanned from one side of the lower jumper to the other side through the insulating rod. For convenience of description, this cooperative state of the auxiliary wheel and the bottom wheel is called "clamping state" or "clamping state".

When the wiring needs to be crossed, generally two sets of this electric power wiring crossing device are required to work together. The first step is to adjust the two sets of power overhead line jumpers to the clamping state, and then operate the remote control mechanism of the first set of electric power overhead line jumpers to clamp the front part of the upper jumper cable, and then lift the insulating rod The front part of the upper jumper cable is crossed from one side (rear) of the lower jumper cable to the other side (front) of the lower jumper cable, so that the jumper or jumper is realized. The second step is to operate the remote control mechanism of the second set of power line jumper to clamp the front part of the upper jumper cable that crosses to the front of the lower jumper cable (equivalent to completing the leading function). The third step is to remove the first set of power jumper from the upper jumper cable and operate the adjustment device to switch to the transmission state, and finally put its upper cover and base on the upper jumper cable, which is completed This ensures smooth take-up of the jumper cables. Under the lifting action of the first set of power overhead jumpers, when the second set of power overhead jumpers is held and moved forward, the upper jumper cable can be pulled from the lower jumper side (rear) Continuously crossing or crossing the line to the other side (forward).

As an implementation, the adjustment device includes a frame, the frame includes two parallel longitudinal bars and a cross bar arranged between the corresponding ends of the longitudinal bars, the two ends of the cross bar are connected with the longitudinal bar through a transverse shaft, and The rod rotates around the horizontal axis, and the auxiliary wheel is correspondingly installed between the two longitudinal rods. It also includes a screw hole passing through the inside and outside of the upper cover and a screw that matches the screw hole. There is a driving groove on the upper end of the screw, and a coaxial fixed An extension rod, the lower end of the extension rod is coaxially fixed with a disc with a diameter larger than that of the extension rod, and the middle part of the cross bar is provided with a transverse cavity that is rotatably matched with the extension rod and the disc.

Because the frame includes two longitudinal bars and two cross bars connected by transverse shafts, and the auxiliary wheels are installed between the two longitudinal bars, so when the frame is raised and lowered, the auxiliary wheels must also be raised and lowered thereupon. The middle part of the cross bar is provided with a transverse cavity, and the extension rod and the disc at the lower end of the screw rod are contained in the transverse cavity. Because the screw, extension rod and disc are coaxially arranged, and the diameter of the disc is larger than the diameter of the extension rod, the screw can only rotate around the axis of the screw relative to the cross bar through the extension rod and the disc, but not along the axis of the screw. The heart line slides up and down. There are two screw holes on the upper cover, and the two screw rods at both ends of the frame are respectively screwed and matched with the two screw holes. Therefore, when the screw rods are screwed into the corresponding screw holes, the frame will be hoisted on the upper cover through the two screw rods. In the cover slot. The outer end of the screw rod is provided with a driving groove, and when the driving groove is pushed to rotate from the outside of the upper cover, the screw rod will be screwed in or out relative to the screw hole. At this time, because the frame cannot rotate with the screw, the frame can only move axially along the screw under the drive of the disc and the extension rod, that is, go deep into the bottom of the groove of the upper cover or away from the bottom of the groove of the upper cover. Wheel lift. Because the horizontal bar is hinged with the vertical axis through the horizontal axis, when the screw rods are rotated, the two screw rods can be asynchronous, that is, one end of the frame is lifted first and then the other end of the frame is lifted, which avoids the inconvenience of synchronously rotating the screw rods.

As an improvement, a slider is fixed on the outside of the longitudinal rod, the length direction of the slider is perpendicular to the length direction of the longitudinal rod and parallel to the axial direction of the screw rod, and the groove wall of the upper cover is provided with a sliding groove corresponding to the slider .

A slider is provided on the outside of the longitudinal rod, and a chute that is slidably matched with the slider is provided on the side wall of the upper cover groove, which can play a role of relative positioning in the front and rear directions when the frame is raised and lowered, and when the frame is installed in the upper cover groove When inside, it can also play a guiding role. Because the length direction of the slide block is arranged parallel to the axial direction of the screw rod, the sliding cooperation between the slide block and the chute can ensure that the frame can only perform stable lifting motion under the drive of the screw rod.

As a further improvement, the outer wall of the upper cover is provided with a scale ring with ring screw holes, and a reference piece is provided on the outer end surface of the screw at one end of the driving groove. When the outer end surface of the screw rod is flush with the outer wall of the upper cover, the end of the driving groove close to the reference piece points to the scale. ring zero.

The screw rotates once, and the screw feeds a pitch in the axial direction. If the screw does not make a full revolution, it is difficult to tell exactly how much the screw has advanced axially. Therefore, the scale ring provided by the ring screw hole on the outer wall of the upper cover can play the role of indicating the axial feed amount, effectively ensuring the consistency of the axial feed of the two screws. The reference piece at one end of the drive slot can mark the start position and end position, avoid confusion at both ends of the drive slot, and help to quickly judge the feed rate. In actual production, the reference piece can be either a hole or a bump.

As an implementation, the operating part includes an operating rod hinged on the lower section of the insulating rod. The lower part of the insulation rod on the side is fixedly provided with a slide rail slidingly matched with the lower hinge shaft, and the length direction of the slide rail is arranged parallel to the length direction of the insulation rod.

Because one end of the operating rod is hinged on the insulating rod, and the middle part of the operating rod is hinged to the lower end of the steering rod, so when the other end of the operating rod is pushed, it is equivalent to pushing the steering rod to move with a lever, which is very labor-saving. When the operating rod is pushed to swing downwards, the operating rod pulls down the insulating rod through the direction changing rod, and the upper end of the upwardly swinging transmission rod will push the upper cover through the upper connecting rod to snap onto the base. Conversely, when the operating lever is pushed to swing up, the upper end of the transmission rod of the lower swing will pull the upper cover away from the base through the upper link to complete the action of opening the cover. The operation is very simple. The upper end of the reversing rod is hinged to the lower end of the insulating rod through the lower hinge shaft, and the lower section of the insulating rod is provided with a slide rail that slides and fits with both ends of the lower hinge shaft, and the extension direction of the slide rail is consistent with the extension direction of the insulation rod, so the slide rail It can play the role of guiding and limiting the lower hinge shaft, that is, guiding and limiting the upper end of the direction change rod, so that the direction change rod can change the swing force of the operating rod into the up and down force of the insulating rod .

As an improvement, the insulating rod includes a main upper rod, several main middle rods and a main lower rod which are screwed together sequentially from top to bottom, and the lower end of the main upper rod and the lower end of the main middle rod are provided with the same inner Screw holes, the upper end of the main middle rod and the upper end of the main lower rod are provided with an outer screw section that is screwed and matched with the inner screw hole. The insulating rod includes an auxiliary upper rod, several auxiliary The middle rod and one auxiliary lower rod, the lower end of the auxiliary upper rod and the lower end of the auxiliary middle rod are provided with the same auxiliary internal screw hole, and the upper end of the auxiliary middle rod and the upper end of the auxiliary lower rod are provided with an auxiliary outer screw that is screwed and matched with the auxiliary inner screw hole. Section, also includes the ability to install the auxiliary middle rod on the main middle rod, the auxiliary lower rod on the main lower rod, and when the outer screw section is tightened into the inner screw hole, the auxiliary upper rod, auxiliary middle rod and auxiliary A double-rod orientation device with coaxial arrangement of the lower rods.

Because the main upper rod and the lower end of the main middle rod are provided with the same inner screw hole, and the upper ends of the main middle rod and the main lower rod are provided with an outer screw section that matches the inner screw hole, so whether it is the main lower rod or which main middle rod can be screwed to the lower end of the main upper pole, and the main lower pole can be screwed to the lower end of any main middle pole, and any two or more main middle poles can be screwed together up and down, so the main upper pole of the insulating rod The rod, the main middle rod and the main lower rod can be freely combined and assembled according to the actual height of the lower span, which is very convenient. Correspondingly, the auxiliary upper pole, auxiliary middle pole and auxiliary lower pole can also be combined and assembled freely, and their combination or assembly structure and principle of combination or assembly are similar and will not be described in detail here.

The electric power erection jumper also includes a double-rod orientation device. The double-rod orientation device structurally installs the auxiliary middle rod on the main middle rod, and installs the auxiliary lower rod on the main lower rod. For the convenience of description, the combined structure of the main upper rod and the auxiliary upper rod is called the upper rod, the combined structure of the main middle rod and the auxiliary lower rod is called the middle rod, and the combined structure of the main lower rod and the auxiliary lower rod is called the lower rod. pole. The double-rod orientation device can not only play the above-mentioned installation and connection functions, but also have the functions of making the middle rod correspondingly installed on the upper rod, making the middle rod correspondingly installed on another middle rod, and making the lower rod correspondingly installed on the middle rod or upper rod role. Specifically, when the outer screw section of the main middle rod is fully tightened into the inner screw hole of the main upper rod, the auxiliary middle rod and the auxiliary upper rod can be easily aligned up and down, so that the auxiliary middle rod can be easily tightened to the corresponding position. The lower end of the auxiliary upper pole plays a role in quickly docking or orienting the auxiliary upper pole and the auxiliary middle pole when docking or orienting the main upper pole and the main middle pole. Since the auxiliary middle rod is installed on the main middle rod and the auxiliary lower rod is installed on the main lower rod, after the above-mentioned docking, the insulating rod and the insulating rod are mutually embedded or limited, which plays an interlocking role, and structurally avoids the When lifting or holding the insulating rod, the reverse rotation of the main middle rod and the main upper rod is caused by unintentional rotation of the insulating rod, or the reverse rotation of the main middle rod and the main middle rod, or the main middle rod and the main lower rod. The reverse unscrewing phenomenon, or the reverse unscrewing phenomenon of the main upper rod and the main lower rod, also ensures the reliability of the segmental screw connection of the insulating rod and the reliability of the segmental screw connection of the insulating rod.

As an implementation, the double-rod orientation device includes a middle sleeve arranged on the upper and lower parts of the main middle rod and slidingly matched with the auxiliary middle rod up and down, the middle part of the auxiliary middle rod is coaxially fixed with a middle nut, and the upper part of the main lower rod There is a lower sleeve that slides up and down with the auxiliary lower rod. The upper end of the main middle rod and the upper end of the main lower rod are coaxially fixed with an optical axis section. The outer wall of the optical axis section is fixed with a positioning slider. There is an optical axis cavity matched with the optical axis section, and the inner wall of the inner screw hole is provided with a positioning chute cooperating axially with the positioning slider, and the inner wall of the optical axis cavity is provided with a positioning slideway connected with the inner end of the positioning chute. The positioning slideway is screwed in the same direction as the thread of the inner screw hole and cooperates with the positioning slider. When the positioning slider rotates to the end of the positioning slideway, the auxiliary upper rod, auxiliary middle rod and auxiliary lower rod are coaxially arranged. The lower end of the outer wall of the rod and the main middle rod is fixed with a sign block corresponding to the positioning chute. The upper end is coaxially fixed with a straight rod, and the upper end of the straight rod is coaxially fixed with a turntable. The lower part of the upper and lower rods is provided with a rotating chamber that cooperates with the rotation of the straight rod and the turntable. The upper and lower rods are coaxially fixed with a lower nut.

There are two middle sleeves on the main middle rod, which are respectively located at both ends of the main middle rod, and the auxiliary middle rod is inserted into the two middle sleeves to slide up and down. Therefore, under the action of the middle nut arranged in the middle of the auxiliary middle rod, The auxiliary middle rod can only slide up and down along the middle sleeve without slipping off, so that the auxiliary middle rod is fixedly installed on the main middle rod in the circumferential direction but can move relative to the main middle rod in the longitudinal direction. The middle nut has three functions: one is to limit the position and prevent the auxiliary middle rod from slipping out of the upper and lower middle sleeves; It is very convenient when the auxiliary middle rod is screwed. The third is that the middle nut can be driven by a wrench to tighten the auxiliary middle rod to the auxiliary upper rod or the upper auxiliary middle rod.

The upper end of the main middle rod and the main lower rod is provided with an optical axis section, that is, a cylindrical section without threads on the outer circumference, so that the main middle rod and the upper part of the main lower rod are provided with an optical axis section and an outer screw section. The positional relationship between the optical axis section and the external screw section is that the optical axis section is on the top and the external screw section is on the bottom, and the two are naturally connected and matched. Correspondingly, an optical axis cavity is provided in the internal screw holes at the lower ends of the main upper rod and the main middle rod. The optical axis cavity is a cylindrical cavity, located at the bottom of the internal screw hole, and coaxially arranged with the internal screw hole. In terms of size, the diameter of the optical axis cavity is the same as that of the optical axis section, but smaller than the inner diameter of the inner screw hole, so as to ensure that the optical axis section can be smoothly inserted into the optical axis cavity through the inner screw hole. A positioning slider is fixed on the outer wall of the optical axis section, and an axially extending positioning chute corresponding to the positioning slider is provided on the inner screw hole and the inner wall of the optical axis cavity. In terms of size, the distance between the outer wall of the positioning slider and the axis of the optical axis section is greater than the inner diameter of the inner screw hole, so as to ensure that only when the positioning slider is slid into the positioning chute, the optical axis section can and can only be inserted into the inner hole smoothly. Inside the screw hole and optical axis cavity. Because the position of the positioning slider relative to the outer screw segment is fixed, and the position of the positioning chute relative to the inner screw hole is also fixed, so when the positioning slider slides into the positioning chute, the corresponding position between the outer screw segment and the inner screw hole The relationship is determined. When the positioning slider slides into the bottom of the positioning chute, the initial end of the thread of the outer thread segment is just aligned with the beginning end of the thread of the inner screw hole, which plays a role in quickly aligning the outer thread segment and the inner screw hole. The inner wall of the optical axis cavity is provided with a positioning slideway that cooperates with the positioning slider. The lower end of the positioning slideway is connected to the upper end of the positioning slideway, that is, the inner end. The positioning slideway is in the same helical shape as the inner screw hole. , when the positioning slider slides into the bottom of the positioning chute, which is the inner end, it just happens to enter the lower end or initial end of the positioning slide. When the main middle rod or the main lower rod is rotated along the inner screw hole, not only the outer screw section will be screwed into the inner screw hole, but also the fixed slider will slide correspondingly along the positioning slideway. The auxiliary middle rod will rotate synchronously thereupon, and the auxiliary lower rod fixed on the main lower rod will also rotate thereupon. When the positioning slider slides to the end of the positioning slideway, the positioning slider and the outer screw section stop screwing in synchronously. At this time, the auxiliary middle rod is just set coaxially with the auxiliary upper rod, and the auxiliary lower rod is just set coaxially with the auxiliary upper rod. In this way, the fast coaxial positioning or orientation of the auxiliary upper rod, the auxiliary middle rod and the auxiliary lower rod is realized. Then screw the auxiliary middle pole into the auxiliary upper pole or the upper auxiliary middle pole, and screw the auxiliary lower pole into the auxiliary upper pole or the auxiliary middle pole. The assembly is very fast and the operation is very simple. After the insulating rod and the insulating rod are screwed tightly, the two lock each other to ensure the reliability of screwing.

At the lower end of the main middle pole and the auxiliary middle pole, a sign block corresponding to the positioning chute can be set, which can indicate the position of the positioning chute, so that the entrance position of the positioning chute can be quickly judged from the appearance, ensuring the rapid insertion of the positioning slider and Tighten.

The auxiliary lower rod is divided into two parts, that is, the upper upper lower rod and the lower lower lower rod. Because the straight rod, turntable, rotary cavity and insulating rod are all arranged coaxially and the diameter of the turntable is larger than the diameter of the straight rod, the upper and lower rods can only rotate relative to each other around their axes but cannot move up and down relative to each other. Such setting is for convenience that the upper end of the auxiliary lower rod can be screwed to the auxiliary upper rod or the auxiliary middle rod. The upper and lower rods are also coaxially fixed with lower nuts, which are also provided for tightening. In this power line jumper, the middle sleeve and the lower sleeve are installed on the main middle pole and the main lower pole through the rotating sleeve, not only for the purpose of forming an integrated structure between the auxiliary middle pole and the main middle pole, and integrating the auxiliary lower pole It forms an integrated structure with the main lower rod, and it is more convenient for the auxiliary middle rod/secondary lower rod to align with the upper auxiliary upper rod/secondary center after the main middle rod/main lower rod is screwed to the upper main upper rod/main middle rod. rod, which facilitates quick assembly.

As an improvement, the hinge shaft is sleeved with a torsion spring that can elastically compress the upper cover on the base.

After the spring is set, the upper cover can be automatically fastened to the base under the action of the spring force when the operating part is not affected by external force (in a natural state), which has the function of automatic buckling or automatic reset after opening the cover, avoiding the operator's back and forth Push the joystick.

As a further improvement, the end section of the operating rod is fixed with an arc plate that fits the outer circumference of the insulating rod, and the end of the arc plate is provided with a positioning hole. Hang with matching hooks.

The end section of the operating rod is set as an arc plate, which can make the inner arc surface of the arc plate close to the outer wall of the insulating rod in the fastened state, that is, when the operating rod is swung down to the lower end of the insulating rod. It will be very comfortable to hold the lower section of the insulating rod and the operating rod while maintaining the snap-fit state, which helps to maintain the snap-fit state for a long time. Hooking the hinged hook at the lower end of the insulating rod to the positioning hole at the end of the arc plate in the buckled state can play a role in locking the arc plate, so that people don’t have to hold the insulating rod and the arc plate with their hands all the time, which saves more effort.

As an improvement, the lower end of the insulating rod is provided with an internal threaded hole, the lower end of the insulating rod is screwed with a positioning cone with a tapered lower end, and the upper even ring of the insulating rod is provided with three positioning rings. The connection has a fixed cone that can be embedded in the ground.

When the power line jumper needs to do long-term jumping, or when the construction manpower is insufficient, the positioning cone can be tightened to the lower end of the insulating rod and inserted into the ground, and then the positioning rope is used to connect the positioning of the upper part of the insulating rod. The ring and the fixing cone on the ground and inserting or burying the fixing cone in the ground can keep the insulating rod upright and fixed on the ground, which realizes the function of automatic support or automatic crossing. Because the three positioning rings are evenly arranged on the top of the insulating rod, the three positioning ropes can ensure that the insulating rod is evenly stressed in any direction on the periphery, thus ensuring the vertical state of the insulating rod.

To sum up, this power line jumper has a reasonable structure, small size, and can be assembled or erected quickly. It can complete the jumping, picking up and leading operations of the upper jumper cable with electricity on the ground, and the operation is simple and does not require Ascending heights not only avoids the hidden dangers of contact points in ascending operations, but also solves the problem of falling from high altitudes in ascending operations, greatly improving work efficiency.

Detailed ways

As shown in the figure, the electric wire jumper includes a vertically extending insulating rod 1. The upper end of the insulating rod 1 is fixed with a base 2. The upper part of the base is provided with a base groove 3 that runs through the front and rear ends of the base 2. The base groove 3 is installed The bottom wheel 4 of carrying cable is arranged. The side of the base 2 is hinged by a hinge shaft 12 with an upper cover 5 that can be fastened to the upper end of the base. The upper cover 5 is provided with an upper cover groove 6 corresponding to the base groove 3 . In the loam cake groove 6, auxiliary wheel 7 is installed by adjusting device, and the adjusting device can regulate the depth of auxiliary wheel in the loam cake groove. Bottom wheel 4 and auxiliary wheel 7 periphery are provided with the ring groove 64 that cooperates with cable, and ring groove 64 groove walls are smoothly transitioned. A support rod 8 is fixed on the outer wall of the base below the hinge shaft 12, and a transmission rod 9 is hinged at the end of the support rod 8. The upper end of the transmission rod 9 is hinged with an upper connecting rod 10, and the upper end of the upper connecting rod 10 is hinged with the upper cover outer wall above the hinge shaft 12 correspondingly. An upper sliding sleeve 63 is arranged on the upper sliding sleeve of the lower section of the transmission rod, and the middle part of the upper sliding sleeve 63 is hinged with an insulating rod 11 extending downward along the insulating rod. The insulating rod 1 is fixed with a middle sliding sleeve 13 which slides axially with the insulating rod 11, the upper part of the insulating rod is provided with a swing chamber 14 which cooperates with the lower part of the transmission rod, and the lower part of the insulating rod is provided with an operating part which drives the insulating rod to move axially. 15.

The main structure of the power line jumper includes a base 2 supported by an insulating rod 1 and an upper cover 5 hinged on the base. The upper cover can be rotated around the hinge to realize buckling on the base or lifting from the base. Function. The base is provided with a base groove, the base groove extends horizontally and runs through both ends of the base, and the base groove mainly provides passing space for passing cables. For the convenience of description, in the horizontal plane, the directions of the two ends through which the base groove penetrates are respectively called front and rear, and the connecting direction is called longitudinal direction, and the directions on both sides of the base groove are called left and right, respectively, and the connecting direction is called Transversely, the direction perpendicular to the horizontal plane is referred to as the vertical or vertical direction. A bottom wheel is installed in the base groove, and the axis line of the bottom wheel rotating shaft is arranged horizontally. The rollers will play the role of rolling support for the passing cables, reducing the passing friction, improving the passing smoothness and ensuring the integrity of the cable skin. The upper cover is also provided with an upper cover groove corresponding to the base groove, and the upper cover groove is also provided through two ends of the upper cover. When the upper cover is fastened on the base, the upper cover groove and the base groove will be connected up and down as a whole. For the convenience of description, the cavity or through groove that connects the upper cover groove and the base groove up and down is called "transfer groove" or "full groove", and the state where the upper cover and the base are fastened together is called the buckled state or closed state. State, the state that the upper cover is lifted from the base is called the lifted state or the open state. An auxiliary wheel is arranged in the slot of the upper cover, and the auxiliary wheel is installed on the upper cover through the adjustment device. The axis line of the rotating shaft of the auxiliary wheel is also extended from left to right or arranged laterally, so that in the buckled state, the rotating shaft of the auxiliary wheel is arranged parallel to the rotating shaft of the bottom wheel. Because the outer circumference of the bottom wheel and the auxiliary wheel is provided with a ring groove that matches the cable, a similar circular gap or cavity will be formed between the auxiliary wheel and the bottom wheel in the fastened state, and this gap or cavity is the transmission The cavity through which the cable passes. For the convenience of description, this cavity is called "transmission cavity" or "cable cavity". The main function of the adjusting device is to adjust the depth of the auxiliary wheel in the groove of the upper cover, that is, to adjust the distance between the auxiliary wheel and the bottom wheel in the buckled state, that is, to adjust the size or thickness of the transmission cavity. When the transmission cavity is thicker than the upper jumper cable, the rolling cooperation of the cable with the bottom wheel and the auxiliary wheel makes the cable smoothly transmitted in the transmission cavity. For convenience of description, this cooperative state of auxiliary wheel and bottom wheel is called " transmission state " or " smooth state ".

In the power line jumper, a support rod is also fixed on the base, and the support rod is located below the connecting hinge shaft between the upper cover and the base. A drive rod is hinged at the end of the support rod, and an upper link is hinged at the upper end of the drive rod, and the upper end of the upper link is hinged with the upper rod part above the hinge shaft correspondingly. Because the hinges on which the upper connecting rod and the transmission rod are hinged are generally arranged parallel to the hinge shaft between the upper cover and the base, rather than vertically, so when the lower end of the transmission rod is swung up and down, the upper end of the transmission rod It will also drive the lower end of the upper link to swing up and down, and because the support rod and the hinge shaft are relatively fixed, the up and down swing of the lower end of the upper link can only be driven by the upper end of the upper link to swing the upper cover around the hinge axis. The fastening or opening of the drive loam cake has just been realized. The upper sliding sleeve of the lower part of the transmission rod has an upper sliding sleeve, and the upper sliding sleeve is hinged with an insulating rod extending vertically downward. Actions are limited to sliding up and down only. The lower end of the insulating rod is provided with an operating part, which can be conveniently driven to move the insulating rod up and down by moving the operating part. At this time, the upper sliding sleeve at the upper end of the insulating rod will divide the force of the insulating rod sliding up and down into the force driving the lower part of the transmission rod to move up and down. And the force that makes the upper sliding sleeve slide up and down along the transmission rod, so that the upper cover can be driven by the transmission of the transmission rod and the upper connecting rod to complete the fastening or opening action. In detail, when the insulating rod is driven upward by the operating part on the ground, the upper end of the insulating rod will drive the lower end of the transmission rod to move up and the upper end of the transmission rod will move down. At this time, the upper end of the transmission rod will move the upper cover from the base through the upper link. Pull up, just finished the loam cake on the control insulation bar top on the ground and open or uncap action. Conversely, when the insulating rod is driven down by the operating member, the support rod will drive the upper cover to snap onto the base through the upper connecting rod, thus completing the upper cover buckling or buckling action on the ground to control the insulating rod. For the convenience of description, all transmission mechanisms that control the upper cover above the insulating rod on the ground to open or buckle the cover are called remote control mechanisms.

When the remote control mechanism cooperates with the adjustment device, three functions can be realized: fixedly clamping the upper jumper cable head and crossing from one side of the lower jumper cable to the other side of the lower jumper cable (jumping or jumping), Fix and hold the upper jumper cable head and guide it forward, pull the upper jumper cable (lead wire), lift the upper jumper cable above the lower jumper and maintain a smooth and stable lifting relationship with the upper jumper cable (pick the thread).

By operating the regulating device, the thickness of the transmission cavity can be controlled. When the transmission cavity is thicker than the upper jumper cable, the rolling cooperation of the cable with the bottom wheel and the auxiliary wheel makes the cable smoothly transmitted in the transmission cavity. In detail, when the cable needs to be smoothly transmitted in the transmission chamber, the upper cover and the base are switched to the buckled state, and the auxiliary wheel is adjusted upward through the adjustment device, that is, the direction of the bottom of the upper cover groove is adjusted. At this time, the transmission chamber is horizontal. The section becomes larger and thicker than the conveying cable. When the cable is conveyed in the cable cavity, due to the gravity of the cable, generally only the bottom wheel will roll and support and limit the lower part of the cable and the two sides of the lower part through its ring groove. Only when the cable shakes upwards and leaves the bottom wheel, the auxiliary wheel The upper part of the cable and the two sides of the upper part will be supported and limited by rolling through its ring groove. Therefore, the surroundings of the cable will be supported and limited by the "elastic" rolling support and rolling position of the auxiliary wheel and the bottom wheel. The movement of the cable in the transmission cavity The range of motion is relatively large, so that the cables can move smoothly in the transmission cavity, and the cables in the transmission cavity can be raised or lowered freely through the base and the upper cover without affecting the transmission speed and skin integrity of the cables. The transmission state is suitable for rapid transmission of the rolling support cable when the upper jumper cable has crossed the lower jumper and the upper jumper has been inserted into the transfer cavity. For convenience of description, this cooperative state of auxiliary wheel and bottom wheel is called " transmission state " or " smooth state ".

When the transmission cavity is thinner than the upper jumper cable, driven by the remote control mechanism, the upper cover is pressed tightly on the base, and the auxiliary wheel and the bottom wheel clamp the upper jumper cable. At this time, the upper jumper cable is relatively fixed on the inside the transmission chamber. In detail, operating the adjusting device will move the auxiliary wheel in the buckled state downward, that is, the auxiliary wheel will be lifted from the bottom of the upper cover groove, at this time, the distance between the auxiliary wheel and the bottom wheel will be reduced, and the transmission cavity will become larger than the cable to be transported. That is, the upper jumper cable should be thinner. In this way, in the buckled state, the auxiliary wheel and the bottom wheel will produce an up and down "clamping force" on the upper jumper cable to clamp the upper jumper cable into the transmission cavity, and the upper jumper cable is relatively fixed on the base and the upper rod. At the same time, at this time, the clamped upper jumper cable head can be spanned from one side of the lower jumper to the other side through the insulating rod. For convenience of description, this cooperative state of the auxiliary wheel and the bottom wheel is called "clamping state" or "clamping state".

When the wiring needs to be crossed, generally two sets of this electric power wiring crossing device are required to work together. The first step is to adjust the two sets of power overhead line jumpers to the clamping state, and then operate the remote control mechanism of the first set of electric power overhead line jumpers to clamp the front part of the upper jumper cable, and then lift the insulating rod The front part of the upper jumper cable is crossed from one side (rear) of the lower jumper cable to the other side (front) of the lower jumper cable, so that the jumper or jumper is realized. The second step is to operate the remote control mechanism of the second set of power line jumper to clamp the front part of the upper jumper cable that crosses to the front of the lower jumper cable (equivalent to completing the leading function). The third step is to remove the first set of power jumper from the upper jumper cable and operate the adjustment device to switch to the transmission state, and finally put its upper cover and base on the upper jumper cable, which is completed This ensures smooth take-up of the jumper cables. Under the lifting action of the first set of power overhead jumpers, when the second set of power overhead jumpers is held and moved forward, the upper jumper cable can be pulled from the lower jumper side (rear) Continuously crossing or crossing the line to the other side (forward).

In this embodiment, the adjusting device comprises a frame 16, which includes two parallel longitudinal bars 17 and a cross bar 18 arranged between corresponding ends of the longitudinal bars. The two ends of the cross bar 18 are connected together with the longitudinal bar through the transverse shaft 19, and the cross bar rotates around the transverse shaft, and the auxiliary wheels 7 are correspondingly installed between the two longitudinal bars. It also includes a screw hole 20 passing through the inside and outside of the upper cover and a screw rod 21 matched with the screw hole, and a driving groove 22 is provided on the upper end surface of the screw rod. The lower end of the screw rod is coaxially fixed with an extension rod, and the lower end of the extension rod is coaxially fixed with a disc with a diameter larger than that of the extension rod, and the middle part of the cross bar is provided with a transverse cavity that is rotatably matched with the extension rod and the disc. Because the frame includes two longitudinal bars and two cross bars connected by transverse shafts, and the auxiliary wheels are installed between the two longitudinal bars, so when the frame is raised and lowered, the auxiliary wheels must also be raised and lowered thereupon. The middle part of the cross bar is provided with a transverse cavity, and the extension rod and the disc at the lower end of the screw rod are contained in the transverse cavity. Because the screw, extension rod and disc are coaxially arranged, and the diameter of the disc is larger than the diameter of the extension rod, the screw can only rotate around the axis of the screw relative to the cross bar through the extension rod and the disc, but not along the axis of the screw. The heart line slides up and down. There are two screw holes on the upper cover, and the two screw rods at both ends of the frame are respectively screwed and matched with the two screw holes. Therefore, when the screw rods are screwed into the corresponding screw holes, the frame will be hoisted on the upper cover through the two screw rods. In the cover slot. The outer end of the screw rod is provided with a driving groove, and when the driving groove is pushed to rotate from the outside of the upper cover, the screw rod will be screwed in or out relative to the screw hole. At this time, because the frame cannot rotate with the screw, the frame can only move axially along the screw under the drive of the disc and the extension rod, that is, go deep into the bottom of the groove of the upper cover or away from the bottom of the groove of the upper cover. Wheel lift. Because the horizontal bar is hinged with the vertical axis through the horizontal axis, when the screw rods are rotated, the two screw rods can be asynchronous, that is, one end of the frame is lifted first and then the other end of the frame is lifted, which avoids the inconvenience of synchronously rotating the screw rods.

A slide block 26 is fixed on the outer side of the longitudinal bar, the length direction of the slide block is perpendicular to the length direction of the longitudinal bar 17 and arranged parallel to the axial direction of the screw rod 21, and the groove wall of the upper cover is provided with a chute correspondingly slidingly matched with the slide block 27. A slider is provided on the outside of the longitudinal rod, and a chute that is slidably matched with the slider is provided on the side wall of the upper cover groove, which can play a role of relative positioning in the front and rear directions when the frame is raised and lowered, and when the frame is installed in the upper cover groove When inside, it can also play a guiding role. Because the length direction of the slide block is arranged parallel to the axial direction of the screw rod, the sliding cooperation between the slide block and the chute can ensure that the frame can only perform stable lifting motion under the drive of the screw rod.

In this power line jumper, the outer wall of the upper cover 5 is provided with a scale ring 28 provided with a ring screw hole, and a reference member 29 is provided on the outer end surface of the screw at one end of the driving groove. When the outer end surface of the screw is flush with the outer wall of the upper cover The end of the drive slot close to the reference member points to the zero point of the scale ring. The screw rotates once, and the screw feeds a pitch in the axial direction. If the screw does not make a full revolution, it is difficult to tell exactly how much the screw has advanced axially. Therefore, the scale ring provided by the ring screw hole on the outer wall of the upper cover can play the role of indicating the axial feed amount, effectively ensuring the consistency of the axial feed of the two screws. The reference piece at one end of the drive slot can mark the start position and end position, avoid confusion at both ends of the drive slot, and help to quickly judge the feed rate. In actual production, the reference piece can be either a hole or a bump.

In this embodiment, the operating member includes an operating rod 30 hinged on the lower section of the insulating rod. A direction changing rod 31 is hinged in the middle of the operating rod. A slide rail 33 that is slidably matched with the lower hinge shaft is fixed on the lower section of the insulating rod on both sides of the rod, and the length direction of the slide rail is parallel to the length direction of the insulating rod. Because one end of the operating rod is hinged on the insulating rod, and the middle part of the operating rod is hinged to the lower end of the steering rod, so when the other end of the operating rod is pushed, it is equivalent to pushing the steering rod to move with a lever, which is very labor-saving. When the operating rod is pushed to swing downwards, the operating rod pulls down the insulating rod through the direction changing rod, and the upper end of the upwardly swinging transmission rod will push the upper cover through the upper connecting rod to snap onto the base. Conversely, when the operating lever is pushed to swing up, the upper end of the transmission rod of the lower swing will pull the upper cover away from the base through the upper link to complete the action of opening the cover. The operation is very simple. The upper end of the reversing rod is hinged to the lower end of the insulating rod through the lower hinge shaft, and the lower section of the insulating rod is provided with a slide rail that slides and fits with both ends of the lower hinge shaft, and the extension direction of the slide rail is consistent with the extension direction of the insulation rod, so the slide rail It can play the role of guiding and limiting the lower hinge shaft, that is, guiding and limiting the upper end of the direction change rod, so that the direction change rod can change the swing force of the operating rod into the up and down force of the insulating rod .

In the power line jumper, the insulating rod 1 is a connectable and detachable multi-section structure, which not only occupies a small space, is convenient to carry, but also is very convenient during construction. The insulating rod includes a main upper rod 34, several main middle rods 35 and a main lower rod 36 which are screwed together from top to bottom, and the lower end of the main upper rod and the lower end of the main middle rod are provided with the same inner screw hole 37. The upper end of the main middle rod and the upper end of the main lower rod are provided with an outer screw segment 38 that is screwed and matched with the inner screw hole. The insulating rod includes a secondary upper rod 39, several secondary middle rods 40 and a secondary lower rod 41 which are screwed together sequentially from top to bottom. The lower end of the secondary upper rod and the lower end of the secondary middle rod are provided with the same secondary The inner screw hole 42, the upper end of the auxiliary middle rod and the upper end of the auxiliary lower rod are provided with an auxiliary outer screw segment 43 which is screwed and matched with the auxiliary inner screw hole. It also includes the ability to install the auxiliary middle rod on the main middle rod and the auxiliary lower rod on the main lower rod, and when the outer screw section is tightened into the inner screw hole, the auxiliary upper rod, auxiliary middle rod and auxiliary lower rod Coaxially arranged twin-rod orienting device.

Because the main upper rod and the lower end of the main middle rod are provided with the same inner screw hole, and the upper ends of the main middle rod and the main lower rod are provided with an outer screw section that matches the inner screw hole, so whether it is the main lower rod or which main middle rod can be screwed to the lower end of the main upper pole, and the main lower pole can be screwed to the lower end of any main middle pole, and any two or more main middle poles can be screwed together up and down, so the main upper pole of the insulating rod The rod, the main middle rod and the main lower rod can be freely combined and assembled according to the actual height of the lower span, which is very convenient. Correspondingly, the auxiliary upper pole, auxiliary middle pole and auxiliary lower pole can also be combined and assembled freely, and their combination or assembly structure and principle of combination or assembly are similar and will not be described in detail here.

The electric power erection jumper also includes a double-rod orientation device. The double-rod orientation device structurally installs the auxiliary middle rod on the main middle rod, and installs the auxiliary lower rod on the main lower rod. For the convenience of description, the combined structure of the main upper rod and the auxiliary upper rod is called the upper rod, the combined structure of the main middle rod and the auxiliary lower rod is called the middle rod, and the combined structure of the main lower rod and the auxiliary lower rod is called the lower rod. pole. The double-rod orientation device can not only play the above-mentioned installation and connection functions, but also have the functions of making the middle rod correspondingly installed on the upper rod, making the middle rod correspondingly installed on another middle rod, and making the lower rod correspondingly installed on the middle rod or upper rod role. Specifically, when the outer screw section of the main middle rod is fully tightened into the inner screw hole of the main upper rod, the auxiliary middle rod and the auxiliary upper rod can be easily aligned up and down, so that the auxiliary middle rod can be easily tightened to the corresponding position. The lower end of the auxiliary upper pole plays a role in quickly docking or orienting the auxiliary upper pole and the auxiliary middle pole when docking or orienting the main upper pole and the main middle pole. Since the auxiliary middle rod is installed on the main middle rod and the auxiliary lower rod is installed on the main lower rod, after the above-mentioned docking, the insulating rod and the insulating rod are mutually embedded or limited, which plays an interlocking role, and structurally avoids the When lifting or holding the insulating rod, the reverse rotation of the main middle rod and the main upper rod is caused by unintentional rotation of the insulating rod, or the reverse rotation of the main middle rod and the main middle rod, or the main middle rod and the main lower rod. The reverse unscrewing phenomenon, or the reverse unscrewing phenomenon of the main upper rod and the main lower rod, also ensures the reliability of the segmental screw connection of the insulating rod and the reliability of the segmental screw connection of the insulating rod.

In this embodiment, the double rod orientation device includes middle sleeves 66 arranged on the upper and lower parts of the main middle rod 35 and slidingly matched with the auxiliary middle rod 40 up and down. The middle part of the auxiliary middle rod 40 is coaxially fixed with a middle nut 67, the upper part of the main lower rod 36 is provided with a lower sleeve 68 which slides up and down with the auxiliary lower rod 41, and the upper end of the main middle rod 35 and the upper end of the main lower rod 36 are coaxially fixed with a The optical axis section 44 is fixed with a positioning slider 45 on the outer wall of the optical axis section 44, and the bottom of the inner screw hole 37 is coaxially extended to be provided with an optical axis cavity 46 cooperating with the optical axis section 44, and the inner wall of the inner screw hole 37 is provided with a The positioning slider 45 is axially slidably matched with the positioning chute 47, and the inner wall of the optical axis cavity 46 is provided with a positioning slideway 65 connected with the inner end of the positioning chute 47, and the positioning slideway 65 and the screw thread of the inner screw hole 37 spiral in the same direction. Set and cooperate with the positioning slider 45 spiral sliding, when the positioning slider 45 rotates to the end of the positioning slideway 65, the auxiliary upper rod 39, the auxiliary middle rod 40 and the auxiliary lower rod 41 are coaxially arranged, and the outer wall of the main upper rod and the main middle rod The lower end is fixedly provided with a sign block 69 corresponding to the positioning chute 47. The auxiliary lower rod 41 includes a lower auxiliary lower rod 48 hinged with the direction changing rod 31 and an upper auxiliary lower rod 49 screwed to the auxiliary middle rod 40. The upper end of the rod 48 is coaxially fixed with a straight rod 50, and the upper end of the straight rod 50 is coaxially fixed with a turntable 51. The lower part of the upper and lower rods 49 is provided with a rotating cavity 52 that is rotatably matched with the straight rod 50 and the turntable 51. The upper and lower rods 49 upper coaxial fixedly are provided with lower nut 53.

There are two middle sleeves on the main middle rod, which are respectively located at both ends of the main middle rod, and the auxiliary middle rod is inserted into the two middle sleeves to slide up and down. Therefore, under the action of the middle nut arranged in the middle of the auxiliary middle rod, The auxiliary middle rod can only slide up and down along the middle sleeve without slipping off, so that the auxiliary middle rod is fixedly installed on the main middle rod in the circumferential direction but can move relative to the main middle rod in the longitudinal direction. The middle nut has three functions: one is to limit the position and prevent the auxiliary middle rod from slipping out of the upper and lower middle sleeves; It is very convenient when the auxiliary middle rod is screwed. The third is that the middle nut can be driven by a wrench to tighten the auxiliary middle rod to the auxiliary upper rod or the upper auxiliary middle rod.

The upper end of the main middle rod and the main lower rod is provided with an optical axis section, that is, a cylindrical section without threads on the outer circumference, so that the main middle rod and the upper part of the main lower rod are provided with an optical axis section and an outer screw section. The positional relationship between the optical axis section and the external screw section is that the optical axis section is on the top and the external screw section is on the bottom, and the two are naturally connected and matched. Correspondingly, an optical axis cavity is provided in the internal screw holes at the lower ends of the main upper rod and the main middle rod. The optical axis cavity is a cylindrical cavity, located at the bottom of the internal screw hole, and coaxially arranged with the internal screw hole. In terms of size, the diameter of the optical axis cavity is the same as that of the optical axis section, but smaller than the inner diameter of the inner screw hole, so as to ensure that the optical axis section can be smoothly inserted into the optical axis cavity through the inner screw hole. A positioning slider is fixed on the outer wall of the optical axis section, and an axially extending positioning chute corresponding to the positioning slider is provided on the inner screw hole and the inner wall of the optical axis cavity. In terms of size, the distance between the outer wall of the positioning slider and the axis of the optical axis section is greater than the inner diameter of the inner screw hole, so as to ensure that only when the positioning slider is slid into the positioning chute, the optical axis section can and can only be inserted into the inner hole smoothly. Inside the screw hole and optical axis cavity. Because the position of the positioning slider relative to the outer screw segment is fixed, and the position of the positioning chute relative to the inner screw hole is also fixed, so when the positioning slider slides into the positioning chute, the corresponding position between the outer screw segment and the inner screw hole The relationship is determined. When the positioning slider slides into the bottom of the positioning chute, the initial end of the thread of the outer thread segment is just aligned with the beginning end of the thread of the inner screw hole, which plays a role in quickly aligning the outer thread segment and the inner screw hole. The inner wall of the optical axis cavity is provided with a positioning slideway that cooperates with the positioning slider. The lower end of the positioning slideway is connected to the upper end of the positioning slideway, that is, the inner end. The positioning slideway is in the same helical shape as the inner screw hole. , when the positioning slider slides into the bottom of the positioning chute, which is the inner end, it just happens to enter the lower end or initial end of the positioning slide. When the main middle rod or the main lower rod is rotated along the inner screw hole, not only the outer screw section will be screwed into the inner screw hole, but also the fixed slider will slide correspondingly along the positioning slideway. The auxiliary middle rod will rotate synchronously thereupon, and the auxiliary lower rod fixed on the main lower rod will also rotate thereupon. When the positioning slider slides to the end of the positioning slideway, the positioning slider and the outer screw section stop screwing in synchronously. At this time, the auxiliary middle rod is just set coaxially with the auxiliary upper rod, and the auxiliary lower rod is just set coaxially with the auxiliary upper rod. In this way, the fast coaxial positioning or orientation of the auxiliary upper rod, the auxiliary middle rod and the auxiliary lower rod is realized. Then screw the auxiliary middle pole into the auxiliary upper pole or the upper auxiliary middle pole, and screw the auxiliary lower pole into the auxiliary upper pole or the auxiliary middle pole. The assembly is very fast and the operation is very simple. After the insulating rod and the insulating rod are screwed tightly, the two lock each other to ensure the reliability of screwing.

At the lower end of the main middle pole and the auxiliary middle pole, a sign block corresponding to the positioning chute can be set, which can indicate the position of the positioning chute, so that the entrance position of the positioning chute can be quickly judged from the appearance, ensuring the rapid insertion of the positioning slider and Tighten.

The auxiliary lower rod is divided into two parts, that is, the upper upper lower rod and the lower lower lower rod. Because the straight rod, turntable, rotary cavity and insulating rod are all arranged coaxially and the diameter of the turntable is larger than the diameter of the straight rod, the upper and lower rods can only rotate relative to each other around their axes and cannot move up and down relative to each other. Such setting is for convenience that the upper end of the auxiliary lower rod can be screwed to the auxiliary upper rod or the auxiliary middle rod. The upper and lower rods are also coaxially fixed with lower nuts, which are also provided for tightening. In this power line jumper, the middle sleeve and the lower sleeve are installed on the main middle pole and the main lower pole through the rotating sleeve, not only for the purpose of forming an integrated structure between the auxiliary middle pole and the main middle pole, and integrating the auxiliary lower pole It forms an integrated structure with the main lower rod, and it is more convenient for the auxiliary middle rod/secondary lower rod to align with the upper auxiliary upper rod/secondary center after the main middle rod/main lower rod is screwed to the upper main upper rod/main middle rod. rod, which facilitates quick assembly.

A torsion spring 54 that can make the loam cake elastically compressed on the base is sleeved on the hinge shaft. After the spring is set, the upper cover can be automatically fastened to the base under the action of the spring force when the operating part is not affected by external force (in a natural state), which has the function of automatic buckling or automatic reset after opening the cover, avoiding the operator's back and forth Push the joystick.

In this embodiment, the end section of the operating rod is fixed with an arc plate 55 that fits the outer circumference of the insulating rod, and the end of the arc plate is provided with a positioning hole 56, and the lower end of the insulating rod is hinged with a Hook 57 that cooperates with positioning hole hook. The end section of the operating rod is set as an arc plate, which can make the inner arc surface of the arc plate close to the outer wall of the insulating rod in the fastened state, that is, when the operating rod is swung down to the lower end of the insulating rod. It will be very comfortable to hold the lower section of the insulating rod and the operating rod while maintaining the snap-fit state, which helps to maintain the snap-fit state for a long time. Hooking the hinged hook at the lower end of the insulating rod to the positioning hole at the end of the arc plate in the buckled state can play a role in locking the arc plate, so that people don’t have to hold the insulating rod and the arc plate with their hands all the time, which saves more effort.

The lower end of the insulating rod is provided with an internally threaded hole 58, and the lower end of the insulating rod is screwed with a positioning cone 59 with a tapered lower end. The upper even ring of the insulating rod is provided with three positioning rings 60, and the positioning ring is connected with a positioning rope 61. The positioning rope The lower end is connected with a fixed cone 62 which can be embedded in the ground. When the power line jumper needs to do long-term jumping, or when the construction manpower is insufficient, the positioning cone can be tightened to the lower end of the insulating rod and inserted into the ground, and then the positioning rope is used to connect the positioning of the upper part of the insulating rod. The ring and the fixing cone on the ground and inserting or burying the fixing cone in the ground can keep the insulating rod upright and fixed on the ground, which realizes the function of automatic support or automatic crossing. Because the three positioning rings are evenly arranged on the top of the insulating rod, the three positioning ropes can ensure that the insulating rod is evenly stressed in any direction on the periphery, thus ensuring the vertical state of the insulating rod.

The power line jumper has a reasonable structure, small size, and can be quickly assembled or erected. It can complete the jumping, picking up, and leading operations of the upper jumping cable with electricity on the ground. The operation is simple and does not require climbing, which avoids The hidden danger of contact points in the operation of ascending heights has also solved the problem of falling from high altitudes in the operation of ascending heights, greatly improving work efficiency.
