Description

Self-compensating J-shaped wire clamp installer

Technical Field

The utility model belongs to the technical field of power equipment, and particularly relates to a self-compensation type J-shaped wire clamp installer.

Background

The J-shaped wire clamp is a non-force-bearing-linked wire clamp and is used for connecting an auxiliary wire of a branch line of a 10kV power line with a main wire of a main line. The J-clamp profile is shown in fig. 1 and includes two interengaging J-shaped guide blocks and a tensioning bolt for guiding the two guide blocks in a similar motion. When the device is installed, an auxiliary line of a branch line is embedded in a line slot of one guide block, and a main line of a trunk line is embedded in a line slot of the other guide block; the two guide blocks are fastened through the matching of the tensioning bolt and the tensioning nut, so that the secondary wire and the main wire are tightly clamped on the guide blocks, and the current connection and guide functions are realized through the guide blocks. The installation of present J type fastener has realized semi-automatization gradually, and its installation flow includes: an operator stands under the main wire, manually fixes the J-shaped wire clamp and the auxiliary wire on the wire clamp installer, and then hooks the J-shaped wire clamp on the main wire through the wire clamp installer; then, a striking part is used for automatically screwing a tensioning bolt or a tensioning nut at the J-shaped wire clamp, so that two guide blocks of the J-shaped wire clamp generate opposite actions, and the function of simultaneously fastening the J-shaped wire clamp relative to a branch line and a main line is realized; and finally, separating the wire clamp installer from the J-shaped wire clamp, and finishing the whole installation process. However, during the installation process described above, it was found that: the screw sleeve at the striking part of the traditional wire clamp installer is directly driven by a striking motor and generates a rotary action, namely only has the rotary action around the axis of the screw sleeve. When the threaded sleeve is meshed with the tensioning nut and the tensioning nut is rotated, the two guide blocks move relatively in the clamping process, the tensioning nut rotates upwards along the tensioning bolt, and the tensioning nut can gradually separate from the threaded sleeve in the process, so that the phenomenon of incomplete contact between the threaded sleeve and the tensioning nut is caused. The incomplete contact phenomenon is slight, so that the assembly process of the J-shaped wire clamp is low in efficiency, and the striking motor needs to be started and stopped frequently for many times so as to ensure that the tensioning nut generates a rotary action; the nut cannot be continuously driven by the threaded sleeve, so that the conditions of low clamp force of the wire clamp, even failure of the wire clamp in combination with the groove and the like are caused. Once the situation occurs, an operator has to perform manual high-altitude operation to remove obstacles, which is extremely time-consuming and labor-consuming, and obviously brings great trouble to the actual wire clamp and groove operation.

The utility model aims to overcome the defects of the prior art and provides a self-compensating J-shaped wire clamp installer so as to provide a basic operation platform for the installation operation of a wire clamp under the condition of high-altitude operation; the utility model can lead the screw sleeve to synchronously act along with the nut of the tensioning nut or the tensioning screw rod all the time in the doubling installation process of the J-shaped wire clamp until the wire clamp is completely clamped in a groove, thereby greatly improving the use safety and the actual installation efficiency of the wire clamp.

In order to achieve the purpose, the utility model adopts the following technical scheme:

Preferably, the elastic member is a jacking pressure spring, the elastic member is sleeved on the transmission shaft, the top end of the elastic member extends upwards and abuts against the bottom end face of the outer guide sleeve, and the bottom end of the elastic member extends downwards and abuts against the driving end of the striking motor.

Preferably, the transmission shaft is a square shaft, and the shape of the sleeve cavity of the outer guide sleeve is matched with the shape of the outer wall of the transmission shaft, so that the transmission shaft and the outer guide sleeve form a spline type rotation stopping fit relation.

Preferably, the top end of the outer guide sleeve is coaxially provided with an annular bulge, one side of the outer guide sleeve is provided with a lock tongue for limiting the outer guide sleeve to generate axial upward movement, and the lock tongue is controlled by a power part to generate radial reciprocating linear movement relative to the outer guide sleeve; when the outer guide sleeve is in a low-position initial position, the lock tongue extends out and is positioned above the annular bulge, so that a one-way spigot fit is formed between the lock tongue and the annular bulge; when the outer guide sleeve is in a high working position, the lock tongue retracts under the control of the power part, and the outer guide sleeve generates axial lift action under the action of the elastic part.

Preferably, the power part is an electromagnet, and the lock tongue and the power part are connected with each other through a reset pressure spring, so that when the power part is started, the reset pressure spring is stressed and compressed to drive the lock tongue to generate retraction action; and a chamfer is arranged at the upper corner end of the top of the lock tongue, so that when the annular protrusion generates downward motion, the reset pressure spring is pressed to generate stressed compression motion.

Preferably, the sleeve cavity of the threaded sleeve is matched with the diameter of the top end of the outer guide sleeve, and a seam allowance of the bottom end face of the threaded sleeve from top to bottom is matched with an upper shaft shoulder of the outer guide sleeve and fixedly connected with the threaded sleeve and the outer guide sleeve through a set screw.

The utility model has the beneficial effects that:

1) on the basis of a traditional rotary screwing object to be rotated, the utility model further provides an axial compensation assembly, so that the purpose of the composite action of rotation and axial advancing of the screw sleeve is realized. When the screw sleeve is screwed to the tightening nut or even the screw sleeve at the tightening screw rod, the screw actions of the tightening nut and the tightening screw sleeve drive the tightening nut and the tightening screw sleeve to generate similar actions, and at the moment, an object to be rotated in the screw sleeve also generates axial action along with the object to be rotated. According to the utility model, through the compound action of the screw sleeve, when the object to be rotated travels a certain distance, the screw sleeve generates compensatory action, namely travels a certain distance synchronously, so that the object to be rotated is reliably positioned in the screw sleeve all the time and forms stable fit with the screw teeth at the screw sleeve, and finally the reliable assembly effect of the screw sleeve relative to the J-shaped wire clamp is ensured.

In conclusion, the utility model can provide a basic operation platform for the installation operation of the on-line wire clamp under the high-altitude operation; the utility model can lead the screw sleeve to synchronously act along with the nut of the tensioning nut or the tensioning screw rod all the time in the doubling installation process of the J-shaped wire clamp until the wire clamp is completely clamped in a groove, thereby greatly improving the use safety and the actual installation efficiency of the wire clamp. When necessary, the remote sensing device can be completely applied to an aerial remote sensing operation environment, namely an on-line remote sensing technology can be served, so that human errors are reduced to the maximum extent, meanwhile, an operator can be far away from the field environment and can carry out remote sensing operation through the display screen, and finally the safety and the efficiency of actual operation are further improved.

2) The compensation component can be realized in various ways, for example, a piston cylinder is assembled below the striking part, and when the striking part rotates and drives the screw sleeve to rotate, the piston cylinder generates lift action to push the screw sleeve to generate axial upward action; alternatively, the striking unit may be driven by a rack and pinion or a crank slider to perform the upward movement. As a further preferred solution of the above solution, the compensation assembly of the present invention is integrated in the striking part, so as to ensure the compactness of the whole structure as much as possible, and is particularly suitable for use in high-altitude working environments with extremely high requirements on volume and weight. Particularly, the compensation assembly is integrated with the striking part through the transmission shaft, the using state of the compensation assembly is guaranteed through the outer guide sleeve and the jacking pressure spring, and finally, the purpose of the established screw sleeve action is achieved simply, conveniently and reliably.

3) The arrangement of the annular projection consists, on the one hand, in forming a shoulder to fix and position the position of the threaded sleeve; on the other hand, a locking notch is formed, so that the self-resetting and self-locking effects of the position of the threaded sleeve are realized by matching with the lock tongue. When an object to be rotated needs to be screwed, the lock tongue retracts under the driving of the electromagnet, at the moment, no block exists above the annular protrusion, the outer guide sleeve generates axial upward movement under the action of the jacking pressure spring, and the composite movement of 'rotation and axial upward' of the screw sleeve is realized. When the assembly is finished, the screw sleeve needs to be reset so as to carry out the next assembly; at the moment, only the threaded sleeve needs to be pressed down, the threaded sleeve and the annular bulge go down together and press the lock tongue, and the lock tongue presses the reset pressure spring and generates retraction action; after the annular protrusion crosses the bolt, the bolt can be stretched out again under the action of the reset pressure spring, and the locking action of the outer guide sleeve and even the threaded sleeve is realized. Obviously, the whole set of flow is simple and reliable, the number of required parts is extremely low, and the operation requirements of compact workpieces with few parts and small volume can be met.

Detailed Description

For the convenience of understanding, the specific structure and operation of the present invention will be further described below by taking the installation and construction of the conventional J-shaped cable clamp as an example, with reference to fig. 1-14:

the utility model can be used in remote control equipment such as robots; during actual assembly, the wire clamp can be fixed on the mechanical arm, and at the moment, the main wire is used as a reference object and is fixed, so that the wire clamp can be completely lifted by the mechanical arm, and the top-mounted wire clamp groove-combining operation relative to the main wire is completed. The traditional wire clamp installation mode is that the wire clamp is hooked from top to bottom relative to a main line, the wire clamp is installed in a mode of jacking from bottom to top relative to the main line in a reverse mode, and no crossing action is needed during working, so that the motion complexity of the mechanical arm can be obviously reduced, the mechanical arm can be conveniently butted with the main line to operate, and the wire clamp is more beneficial to being used by a high-altitude remote sensing robot.

Before actual installation, the conventional wire clamp shown in fig. 1 needs to be modified, that is, a screw is driven into the side of the upper guide block a as shown in fig. 2, so as to form a set anchor g. Of course, the anchor post g may be formed by driving a rivet or welding a post in practice. The position of the anchor post g should correspond to the position of the slide groove 13a at the anchor mounting portion 10 for later installation.

In practice, the specific structure of the present invention is shown in fig. 3-13, and the main structure includes a positioning and mounting portion 10 for fixing a wire clip, a sub-wire locking clip 40 for fixing a sub-wire B, and a main wire guiding clip 30 for accommodating a main wire a. When the main line and the auxiliary line are installed in place, the striking part with the compensation component 23 is used for jacking and rotating the tensioning nut d, and finally the effect of tightly fixing the line clamp, the main line A and the auxiliary line B is achieved.

Of course, the present invention can be applied to a hanging type mounter as an add-on, and as shown in fig. 14, the working purpose can be achieved.

For convenience of description herein, the following description will be made, taking as an example the top type wire clamp mounting structure:

first, positioning installation part 10

The positioning and mounting portion 10 is shaped as shown in fig. 3-7 and fig. 10-13, and includes a base 11, two clamping rods 12 or clamping plates extending upward from the base 11, and a positioning assembly 13. The two clamping rods 12 are arranged in parallel on the plate surfaces, and a sliding groove 13a is correspondingly arranged on one or two inner side surfaces forming the adjacent surfaces, so that a positioning anchor post g at a wire clamp position shown in fig. 2 can be clamped in; the state after the click-in is shown in fig. 6. Because the present invention adopts the top-up assembly method, when the striking part 20 strikes from bottom to top, it is preferable to ensure that the upper guide block a is in a fixed state, so as to facilitate the striking part 20 with self-compensation function to screw the tensioning nut d and drive the tensioning nut d and even the lower guide block b to generate an upward motion relative to the upper guide block a.

When the upper guide block a is required to be in the fixed posture, as shown in fig. 5-6 and fig. 12-13, on one hand, when the sliding groove 13a is opened, the lower groove end of the sliding groove 13a does not reach to the bottom, that is, a sealing end exists, and at this time, the lower groove end naturally forms a spigot step for limiting the upper guide block a to descend. On the other hand, the upper groove end of the slide groove 13a is required to be inserted with the anchor post g from the top down and to restrict the upper guide block a from moving upward, and therefore, a locking mechanism is arranged as shown in fig. 12 to 13. The locking mechanism comprises a C-shaped locking hook 13b, the bottom end of the locking hook 13b is hinged on the clamping rod 12, and the top end of the locking hook 13b is bent and penetrates through the clamping rod 12 to extend into a groove cavity of the sliding groove 13 a. In a natural state, the locking hook 13b is controlled by the locking spring to be always elastically pressed into the groove cavity of the sliding groove 13a, and has a natural unidirectional locking function of 'positioning anchor column can move downwards but can not move upwards'. When the locking hook 13b is required to be actively opened so that the wire clamp is separated from the positioning installation part 10, the locking electric push rod 13d can be started, the piston rod end of the locking electric push rod 13d descends and pulls down the anchor point 13c at the locking hook 13b, and then the locking hook 13b can be actively started, so that the upper groove end of the sliding groove 13a forms an opening state which is convenient for the wire clamp to be separated.

Secondary line and secondary line locking clip 40

The secondary wire locking clip 40 is shown in fig. 4-5 and 12-13, and its main structure is formed by combining a secondary wire groove 43, a secondary lock lever 41 and a transverse lever 42. Two sets of secondary lock rods 41 are matched with one set of transverse rods 42 to form a three-dimensional frame structure so as to facilitate better lateral hooking of the secondary line B. The secondary line groove 43 is designed to improve threading efficiency, and can be matched with the secondary lock rod 41 to better bite the secondary line, so that the secondary line B can be conveniently and quickly installed. Because the auxiliary line B is usually installed on the ground, attention needs to be paid to how the auxiliary line B can be freely separated from the utility model after being lifted off and combined with the main line clamp; in view of this, the secondary lock lever 41 of the present invention employs a "T" type plate structure. When the auxiliary line B fixing device is used, one end of the horizontal section of the auxiliary locking rod 41 is hinged to the clamping rod 12 through the support lug 41a, and the other end of the horizontal section forms a locking end 41B with the end portion gradually tilted upwards and is used for being matched with the auxiliary line groove 43 to realize the engagement type fixing operation of the auxiliary line B. The vertical section of the secondary lock rod 41 extends towards the clamping rod 12 and forms a switch end 41c, and the piston rod end of the locking electric push rod 13d horizontally passes through the adjusting hole on the clamping rod 12 and forms a leaning fit or a hinged fit with the switch end 41c of the secondary lock rod 41. Therefore, when the locking electric push rod 13d does a process action, the switch end 41c is driven to move upwards, and the auxiliary lock rod 41 swings, so that the position of the auxiliary line can be positioned by utilizing the matching of the buckling structure of the locking end 41b and the auxiliary line groove; with particular reference to figure 5.

Third, main thread guide clip 30

The main line guide clip 30 is designed mainly for the purpose that when the present invention is pushed up from bottom to top, the "V" shape design with the opening of the main line guide clip 30 facing upwards can effectively guide the main line a to go down until the main line a falls into the matching groove 31a of the main guide fork 31 at the main line guide clip 30. When the wire clamp is fixed, the head end notch e of the lower guide block b at the wire clamp is just as high as the matching groove 31a or has a slight height difference, so that the main wire can reliably fall into the head end notch e.

In the specific design, the main line guide clip 30 includes a main guide fork 31 and an auxiliary guide fork 32 as shown in fig. 3-7 and fig. 10-13, which are all aimed at guiding by the forks, so that the main line can slide into the main line guide clip 30 along the guide surface more conveniently, and finally fall into the notch e at the head end of the lower guide block b; the structure solves the problems of inaccurate installation position of the wire clamp, slow installation of the wire clamp and the like in the traditional sense, simplifies the action process and is more suitable for a robot. The auxiliary guide fork 32 adopts a movable guide fork, plays a role in guiding, does not interfere with the main line to slide out, and is obviously more convenient and faster in operation.

Fourthly, the striking part 20

The striking part 20 is also the present invention. In fact, the striking portion 20 is an indispensable part in the cleat holder; however, the conventional striking part is to tighten the nut of the tension bolt c or the tension nut d by the spin of the nut 21, thereby performing a tightening function. The striking part 20 of the present invention has the functions of screwing and self-compensation, and particularly can perfectly match the upward movement of the lower guide block b under the condition that the upper guide block a is fixed, and finally, the main line and the secondary line are simultaneously clamped through the two guide blocks.

The striking part 20 according to the present invention is specifically constructed as shown in fig. 4 and fig. 7 to 11, and its main portion includes a threaded sleeve 21, a striking motor 22 for driving the threaded sleeve 21 to rotate, and a compensation assembly 23 for providing a compensation function of the threaded sleeve 21. Wherein:

the driving end of the striking motor 22 is coaxially and fixedly connected with a transmission shaft 23a so as to realize power transmission, the transmission shaft 23a is externally stopped and rotatably sleeved with an outer guide sleeve 23b, and the top end of the outer guide sleeve 23b is fixed with a threaded sleeve 21. When the striking motor 22 works, the transmission shaft 23a rotates along with the striking motor, and drives the outer guide sleeve 23b to rotate through the key connection with the outer guide sleeve 23b, and finally drives the screw sleeve 21 to rotate.

Meanwhile, an annular protrusion 23d is further disposed at the outer guide sleeve 23b, as shown in fig. 8-9, so as to form a rabbet fit with the electromagnetic lock. The electromagnetic lock comprises an electromagnet forming a power piece 23f, a bolt 23e positioned at the working end of the electromagnet and a reset pressure spring 23g connecting the bolt 23e and the electromagnet. When the device works, the lock tongue 23e always extends out to the outer guide sleeve 23b under the action of the reset pressure spring. When the screw sleeve 21 is in the initial state, i.e. the low position state, as shown in fig. 8, the latch tongue 23e is located just above the annular protrusion 23d, so as to press the annular protrusion 23d, so that the outer guide sleeve 23b and thus the screw sleeve 21 do not go upward any more. When the threaded sleeve 21 needs to be used, the electromagnet is powered on at the moment, the bolt 23e is sucked, the bolt 23e overcomes the force of the reset pressure spring 23g and retracts, and therefore the annular protrusion 23d is unlocked; subsequently, the outer guide sleeve 23b moves upwards under the action of the jacking compression spring forming the elastic part 23c, so that the screw sleeve 21 is driven to move upwards, and the purpose of self-compensation action is achieved. When the screw sleeve 21 moves upwards, the outer guide sleeve 23b moves upwards relative to the transmission shaft 23a, and meanwhile, the transmission shaft 23a applies a rotating force to the screw sleeve 21 through the outer guide sleeve 23b, so that the combined type self-compensation action function of rotation and axial upwards movement of the screw sleeve 21 is ensured.

To facilitate a further understanding of the present invention, the actual workflow of the present invention is described herein below in conjunction with FIGS. 1-13:

1) after the conventional J-shaped wire clamp shown in figure 1 is taken, the wire clamp is drilled and screws are installed, so that the novel wire clamp with the positioning anchor posts g shown in figure 2 is formed.

2) The screw sleeve 21 is pressed down, so that the screw sleeve 21 is reset downwards; at the same time, the locking electric push rod 13d moves downward, and the locking hook 13b is forcibly opened. When the locking electric push rod 13d returns and pulls the anchor point 13c at the locking hook 13b, the wire clamp is installed only after the locking hook 13b is completely in an open state. And then, installing the novel wire clamp in the step 1), wherein the positioning anchor post g can move downwards along the direction of the sliding groove 13a due to the existence of the positioning anchor post g, so that the novel wire clamp has the advantages of rapid installation and installation position. The wire clamp can quickly and accurately reach the working position along the sliding groove 13 a. After the positioning anchor post is clamped into a working position as shown in figure 6; among the two positioning anchor posts g, the lower positioning anchor post is blocked by the lower groove end of the sliding groove 13a, and the upper positioning anchor post is blocked by the hook head of the locking hook 13b with the locking tension spring in the subsequent step 4), so that the upper guide block a of the wire clamp is reliably fixed; at this time, the head end notch e of the lower guide block b is directed upward, instead of the downward installation of the conventional pull-down type clamper. And in the process that the wire clamp descends along the sliding groove 13a, the locking hook 13b is in an open state, namely, the piston rod end of the locking electric push rod 13d continuously applies a downward pulling force to the anchor point 13c at the locking hook 13 b.

3) Since the locking electric push rod 13d is always in the return state, the sub lock lever 41 is also always in the open state, that is, the locking end 41b is always located in the accommodating groove 12 a. After the clip is installed, the secondary wire is inserted through the secondary wire slot 43. Then, the locking electric push rod 13d performs a progressive operation, so that the switch end 41c of the sub lock lever 41 is pushed by the guiding operation of the adjusting hole and the slide rod 13e, and the sub lock lever 41 performs a swinging operation until the sub lock lever 41 engages with the sub wire groove to bite the sub wire. At this time, the sub-line is located between the upper guide block a and the lower guide block b as shown in fig. 2, but is not yet reliably installed; the auxiliary locking rod 41 and the auxiliary line groove 43 are matched to effectively fix the auxiliary line, so that the condition that the line clamp fails to be connected with the groove due to falling and moving of the auxiliary line is prevented.

4) When the locking electric push rod 13d performs process action, the piston rod end of the locking electric push rod 13d gradually releases the pressing of the anchor point 13c at the locking hook 13b, and the locking hook 13b resets under the action of the locking tension spring, so that the wire clamp is clamped, and the ascending and descending limiting actions of the upper guide block a at the position of the wire clamp are completed.

5) After the fixing of the secondary line is completed and the latch hook 13b is reset, the electromagnet forming the power element 23f is energized to draw the latch tongue 23e and release the outer guide sleeve 23b with the annular protrusion 23d, as shown in fig. 9.

6) When striking starts, the nut 21 is rotated and the tension nut d is rotated. In the process of screwing the tensioning nut d of the wire clamp, the lower guide block b and the tensioning nut d continuously move upwards; due to the elastic force of the jacking pressure spring below the outer guide sleeve 23b, the outer guide sleeve 23b also performs compensation type ascending movement until striking is completed.

7) After the wire clamp is assembled, the locking electric push rod 13d generates return stroke action to drive the secondary wire locking clamp 40 to reset and release the secondary wire, meanwhile, the locking electric push rod 13d also drives the lock hook 13b to act, and the lock hook 13b is actively opened. And then, the utility model is pulled down, completely separated from the wire clamp, and the wire clamp is left on the main wire positioned in the high altitude, and finally the whole wire clamp and the flow are finished.

The main wire is assembled from the top up from the bottom up because the utility model is the clip flip-chip type top up mounting structure. In actual work, the device is lifted by the mechanical arm to complete work, so the main line is fixed, and the whole device is provided with the auxiliary line to move. Before the main line is dug, the auxiliary guide fork 32 is reset under the action of gravity, and the main line is connected from bottom to top by the mechanical arm. After the grooving is completed, the present invention is withdrawn from the top to the bottom, and the auxiliary guide fork 32 will rotate by itself to avoid the interference of the main line to be separated.
