Description

Mobile contact net for eliminating construction errors

Technical Field

The utility model belongs to the field of electrified railway mobile contact networks, and particularly relates to a mobile contact network for eliminating construction errors.

Background

With the propulsion of the electric traction of railways, the electric locomotives are adopted to replace the internal combustion locomotives in the transportation of China railway trunks. Electrification is realized in a cargo loading and unloading line or warehousing maintenance. At present, a rigid movable contact net system is adopted, but the existing rigid movable contact net system has extremely high cost, complex structure and inconvenient installation, has high requirements on the use conditions of the line and poor structural reliability; the motor is used for driving the rotating support to rotate so as to drive the moving section of the overall moving contact net to move to one side of a rail, in the mode, the bus bar is integrally arranged at the tail end of the rotating support, and the motor is more and difficult to control the synchronism of the motor or the driving of the electric push rod.

With the innovation of the electrified railway technology, technical personnel in the field continuously innovate, upgrade the technical innovation and provide an electrified mobile contact network which can meet the requirements of cargo handling lines or warehousing maintenance.

SUMMERY OF THE UTILITY MODEL

In the prior art, a flexible movable contact net is also used, and a motor is used for directly dragging a catenary on one side of the flexible contact net to move a contact line to one side of a rail; also there is too high contact net of cantilever that adopts mechanical drive, even if too high also can not move the contact net to the railway outside completely, still can influence the loading and unloading of large-scale goods, if adopt and rotate the cantilever, with contact net horizontal hunting to railway one side, also there is the defect that can not swing railway one side completely, its existence is following not enoughly:

1. expansion with heat and contraction with cold certainly can cause the extension of contact wire, catenary, probably leads to bow net trouble (train pantograph and catenary trouble), for example the compensation arrangement that adjusts the cable tension falls to the ground, the cantilever skew, locator breaks away from serious incident such as. If the contact wire is loosened and wound on a pantograph (a transverse plate which is high above the locomotive head) of the train, the contact net rod is dragged down, the locomotive falls off the track, and the carriage falls down, so that the consequence is very serious.

2. The carrier cable and the contact line are fixedly arranged on the rotating wrist arm, and construction errors exist in the spacing and verticality between the stand columns and the tension degree of the carrier cable and the contact line between the wrist arms. According to the main technical policy of the existing railway, 5000t heavy-load freight trains are driven, the effective length of the arrival and departure line of a station is 1050m, 10000t heavy-load freight trains are driven on a special coal conveying line, and the effective length of the arrival and departure line of part of stations is 1700 m. For such a long-distance heavy-duty train, for example, a ten thousand-ton heavy-duty train of 1400m to 1700m, due to the influence of thermal expansion and cold contraction and the existence of construction errors, when the moving contact net rotates above the railway or to the side of the railway, the moving contact net may not rotate in place.

The existing method is that a weight is arranged at one end of a mobile contact network, a dragging mechanism is arranged at the other end of the mobile contact network, and a catenary cable and/or a contact line are/is pulled by the dragging mechanism, so that the contact line is moved from one side edge of a rail to the upper side of the rail or from the upper side of the rail to one side edge of the rail.

Through the continuous research and practice of the applicant, the above solution enables the effective implementation of driving the catenary and/or contact line to move to one side of the rail or above the rail, but in practice a new problem arises: the cantilever is arranged to rotate rightwards to drive the contact line and the catenary to move to one side of the rail, due to the characteristic of expansion with heat and contraction with cold of the contact line and the catenary, when the rightmost cantilever moves to one side of the rail (the cantilever is approximately parallel to the rail and can be understood as completely swinging to one side to leave a space above the rail), the rest of the cantilevers do not completely rotate to one side of the rail (the cantilever can be understood as not completely swinging to the rail once in the whole overhead contact system, for the long-distance overhead contact system, the swinging stops when swinging to the upper side of the rail side, because the rightmost cantilever swings in place), the rotation cantilever farther away from the right cantilever is smaller in offset, namely when the rightmost cantilever stops rotating, the rest of the cantilevers do not rotate to the position, particularly for the heavy-load train suitable for the long distance, the displacement is about 1600m, when the rightmost cantilever stops rotating after being in place, other cantilevers far away from the right-end cantilever are still in a state of not rotating in place, even above the side of a rail, so that the loading and unloading operation of other goods such as large goods yards, containers and the like can be influenced; in addition, due to the fact that the pantograph does not rotate in place, the pantograph is poor in power taking and contact or cannot contact and take power, and the driving-in or driving-in position of the freight train is affected.

In order to realize the purpose, the applicant provides a set of technical scheme which can effectively solve the defect that the movement of a catenary and a contact line is not in place in the existing mobile contact network, and compared with a rigid contact network, the mobile contact network has the advantages of lower cost, more reliable operation, less weather influence and simpler maintenance; the application provides a contact net still overcomes original adoption and drags the mode and remove not enough, changes to carry out with the mode that gravity supplyed

And the movement is effectively improved on the basis of the existing contact net, and the integral movement with longer distance (1600m-1700m) can be realized. The locomotive can meet the requirement of cargo handling lines or warehousing maintenance of the existing freight trains of the locomotives, and can be effectively applied to heavy-duty trains such as ten-thousand-ton trains.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus consistent with certain aspects of the utility model, as detailed in the appended claims.

As shown in fig. 1, a schematic diagram of a conventional mobile catenary is set such that a cantilever rotates rightwards to drive a contact line and a catenary to move to one side (non-working position) of a rail, because the contact line and the catenary have the effects of removing construction errors and thermal expansion and cold contraction, when a rightmost cantilever a moves to one side of the rail (the cantilever is nearly parallel to the rail to give way to a space above the rail), the rest of the cantilevers (the cantilevers a to d) do not completely rotate to one side of the rail (it can be understood that at least one cantilever in the whole catenary does not completely swing to the rail once, for a long-distance catenary, the swing stops above the rail side, because the rightmost cantilever already swings in place), the offset of the rotating cantilever farther from the right cantilever is smaller, that is, that when the rightmost cantilever stops rotating, the rest of the cantilevers do not rotate in place, especially for a heavy-duty train suitable for a long distance, the moving contact net is about 1600m, when the rightmost cantilever stops rotating after being in place, other cantilevers far away from the right-end cantilever are still in a state of not rotating in place, even above the side of a rail, and therefore the loading and unloading operation of other goods such as a large goods yard, a container and the like can be influenced; in addition, due to the fact that the pantograph does not rotate in place, the pantograph is poor in power taking and contact or cannot contact and take power, and the driving-in or driving-in position of the freight train is affected.

As shown in fig. 2, the utility model provides a mobile overhead line system for eliminating construction errors, wherein the overhead line system is provided with a plurality of supporting devices, and further comprises a catenary cable and/or a contact line;

In at least one of the support means, the maximum horizontal travel distance (L1) of the messenger and/or contact line in the horizontal direction during rotation from the active position to the inactive position or vice versa can be greater than the corresponding support means rotation horizontal distance L2.

What needs to be added is: in the process of moving the carrier cable and/or the contact line, a plurality of supporting devices are pulled or pushed to rotate to working positions or non-working positions,

The power supply adopts any one of the following modes:

As a preferred embodiment, in this embodiment, when at least one support device in the moving catenary stops rotating, the catenary and/or the contact line can further move on the support devices.

The horizontal distance of movement of the carrier cable and/or contact line in the horizontal direction is greater than the horizontal distance of rotation of the support means.

The embodiment also comprises a force transmission mechanism, wherein the force transmission mechanism is used for converting the force further pulled by the catenary and/or the contact wire into pushing force or pulling force to act on the supporting devices, and pushing or pulling a plurality of supporting devices to further rotate so as to realize stroke compensation.

As a preferred embodiment, in this embodiment, when at least one support means (typically the last support means) of the catenary stops rotating, the catenary and/or contact wire can further move on the support means. The horizontal distance of the movement of the carrier cable and/or the contact line along the horizontal direction is larger than or equal to the rotating horizontal distance of the supporting device. As shown in fig. 2, after the messenger and/or contact wire has moved from point a to point B, the horizontal distance L1> L2 that the messenger and/or contact wire has moved, as can be seen in fig. 2, is now used to pull the messenger and/or contact wire through an external pulling mechanism (not shown in fig. 2, see fig. 3) over a number of support devices; so that the messenger and/or contact line moves from point B to point B' and the total distance the messenger and/or contact line travels in the horizontal direction is L2.

As shown in fig. 4, the messenger and/or contact wire moves from point a to point a ', and since the messenger and/or contact wire is slidably disposed on the support means, the messenger and/or contact wire has a slippage relative to the support means during movement, and therefore moves from point a to point a' by a horizontal distance L1, which corresponds to a horizontal distance L2 for the support means to rotate, i.e., L1 is always greater than L2 at any position during rotation as long as the messenger and/or contact wire has a relative slippage relative to the support means during movement.

Of course, there may be at least one rotation mechanism for driving the support means to rotate, said rotation mechanism driving the support means to rotate to move said messenger and/or contact wire to a non-operative oscillation.

Supplementary explanation is as follows: the purpose is to make the carrier cable, the contact wire and the supporting device all rotate to the non-working position, the supporting device can be driven to rotate by the pulling force of the carrier cable and/or the contact wire in a mode of pulling the carrier cable and/or the contact wire, the supporting device can also be driven to rotate by a rotating motor, and the carrier cable and/or the contact wire is driven to move to the non-working position by the rotation of the supporting device.

The maximum innovation point of the contact net is that the maximum horizontal moving distance of the catenary and/or the contact line along the horizontal direction can be more than or equal to the length of the rotating radius of the supporting device. The other angle is that the carrier cable and/or the contact line are not fixed on the supporting device; the catenary and the contact line shown in fig. 1 are fixed on the cantilever, the distance that any cantilever rotates or the catenary pulls the catenary to move in the horizontal direction is less than or equal to the rotation radius of the cantilever, and particularly in a long-distance moving contact network, due to construction errors and the influence of thermal expansion and cold contraction, in summer, for example, when the cantilever a stops rotating in place, the cantilever c and the cantilever d farther away from the cantilever a cannot rotate in place.

In this patent with the gliding setting of whole carrier cable or contact line on a plurality of strutting arrangement, firstly overcome construction error's influence, no matter winter or summer, effectual reduction or neglect expend with heat and contract with cold and to strutting arrangement pivoted influence.

Insofar, it will be appreciated by those skilled in the art that, i.e. in the case where the messenger and/or the contact wire is slidable, the maximum horizontal travel distance of said messenger and/or contact wire in the horizontal direction can be greater than the horizontal distance of rotation of the respective support means.

As a preferred embodiment, to better ensure a better rotation of the support arm to the rest position in case of movement of the catenary: this patent provides several solutions as follows:

the first method comprises the following steps: the device also comprises a force transmission mechanism, wherein the force transmission mechanism is used for converting the force further pulled by the carrier cable and/or the contact wire into pushing force or pulling force to act on the supporting devices, and pushing or pulling a plurality of supporting devices to further rotate so as to realize stroke compensation.

And the second method comprises the following steps: the root of at least one supporting device, namely the connecting position of the supporting device and the upright post is provided with a rotating mechanism, such as a rotating motor, and the scheme can be used independently or simultaneously used for the first and the second.

Thirdly, the counterweight device is connected with the supporting device through a pull rope; the counterweight device is used for assisting the supporting device to rotate to the non-working position. This scheme may be used alone or in combination with at least two of the first and second.

In the utility model, the carrier cable can move relative to the supporting device; or the contact wire can be movable relative to the support means. The problem of electrical isolation can be solved by mounting an insulator on the support device.

It should be added that the supporting structure 7 in this embodiment mainly plays a role of dragging the catenary or the contact line, and there are various embodiments of the supporting structure, such as a sliding head (as shown in fig. 5 and 5A), a sliding ring (as shown in fig. 6, 6A and 6B, where fig. 6B is a structural schematic diagram of the catenary sliding in the sliding ring, a sliding ring is extended in a length direction to form a sleeve, as shown in fig. 6C, the sliding or sleeve belongs to one of the supporting structures, and the sliding ring and the sleeve belong to a protection range of the supporting structure), a groove structure (as shown in fig. 7 and 7A), and the like, and the supporting structure is as long as the supporting structure can support the catenary.

Supplementary explanation is as follows: this embodiment provides an implementation way that the contact line drives the supporting structure to slide on the supporting device: as shown in fig. 8, the contact line is held at both ends of the supporting structure, as shown at the position of a point in fig. 8; the support device is slid to the left and right on a sliding bar in the supporting structure 7, as shown in the position of the b-point in fig. 8.

As a preferable embodiment, the present embodiment further comprises a force transmission mechanism 9, wherein the force transmission mechanism 9 is used for directly or indirectly applying the pushing force or the pulling force generated in the movement process of the catenary to the supporting device 3 or the supporting structure 7 so as to pull or push the supporting device to rotate 7; and/or

The force transmission mechanism is used for applying pushing force or pulling force formed in the contact line moving process to the supporting device or the bearing structure so as to pull or push the supporting device to rotate. The arrangement of the contact line with respect to the force transmission mechanism is the same as that on the messenger.

As shown in fig. 9 to 12, the force transmission mechanism in this embodiment comprises an elastic mechanism, one end of which is directly or indirectly connected to the carrier cable, the carrier cable moves to compress or stretch the elastic mechanism, and the pushing force or pulling force generated by the elastic mechanism acts on the support device or the supporting structure, so as to push or pull the support device to rotate.

It should be noted that fig. 9 shows that the other end of the force transmission mechanism 9 acts on the supporting structure 7, the carrier cable moves to compress the force transmission mechanism, and the pushing force formed by the force transmission mechanism 9 acts on the supporting structure 7 to push the supporting device to rotate.

In fig. 10 and 11, the other end of the elastic mechanism directly or indirectly acts on the supporting device, the carrier cable moves to compress the force transmission mechanism, and the pushing force formed by the force transmission mechanism acts on the supporting device so as to push the supporting device to rotate.

As shown in fig. 12, the other end of the elastic mechanism directly or indirectly acts on the supporting device, the carrier cable moves the tensile force transmission mechanism, and the tensile force formed by the force transmission mechanism 9 directly or indirectly acts on the supporting device, so that the supporting device is pulled to rotate.

As shown in fig. 13 and 14, the support structure is a sleeve, the carrier cable or the contact wire is inserted into the sleeve, the sleeve is fixed on the support device, the carrier cable moves to the right to compress the force transmission mechanism, and the other end of the force transmission mechanism is pressed on the sleeve to push the sleeve to move, so that the support device is pushed to rotate. Of course, the other end of the force transmission mechanism (spring) can also act on the left side of the sleeve to pull the rotating device to rotate (not shown in the figure).

One end of the elastic mechanism is directly or indirectly connected with a contact line, the other end of the elastic mechanism directly or indirectly acts on the supporting device or the supporting structure, the other end of the elastic mechanism acts on the supporting device or the supporting structure, the contact line moves to compress or stretch the elastic mechanism, and pushing force or pulling force formed by the elastic mechanism acts on the supporting device or the supporting structure so as to push or pull the supporting device to rotate. It should be added that the method of attachment to the contact wire is not shown and reference is made to the attachment scheme to the carrier wire.

As a preferred embodiment, further comprising a clamping mechanism, said clamping mechanism 12 being arranged on the messenger wire and/or the contact line;

the clamping mechanism is arranged on the carrier cable in the following mode:

the first method comprises the following steps: the gripping means 12 are arranged on the carrier line inside the supporting structure 7 (as shown in fig. 17); and/or

And the second method comprises the following steps: the gripping mechanism 12 is located on the messenger 1 on one side of the support structure or on both sides (fig. 15 or fig. 16);

The clamping mechanism is positioned on the catenary at one side of the sliding contact position of the catenary and the supporting device or on the catenary at two sides of the sliding contact position of the catenary and the supporting device; and/or the clamping mechanism is positioned on the contact line on one side or both sides of the sliding contact position of the contact line and the supporting device. The sliding contact position is the position where the carrier cable is in sliding contact with the bearing structure, the clamping mechanism in the embodiment mainly plays a role in limiting, half clamping is arranged on any side of the sliding contact position, and full clamping is arranged on both sides of the sliding contact position; if both sides are arranged, the embodiment is called as the situation without clamping.

It should be added that, in the operation process, when one supporting device on the most edge swings to the right position and stops rotating (the supporting device can be stopped by adopting a limit structure which is not a point protected by the patent and can be stopped by adopting any mode or the existing mode), the other supporting devices far away from the supporting device which stops rotating do not swing to one side of the rail completely, at the moment, the carrier cable and/or the contact wire are further pulled, the clamping mechanism abuts against the supporting structure, and the supporting structure is used for pushing the supporting device to rotate further by abutting. Of course, this is the key technical idea at the heart of this patent technology, and conventionally, since the catenary and the contact wire are fixed on the supporting device, when the supporting device at the extreme side is rotated to the position, the catenary and/or the contact wire cannot be further pulled, so that the rest of the supporting devices in the catenary cannot be rotated to the position.

In order to enable a person skilled in the art to clearly understand, the requirement fully disclosed in the patent is met, and why the situation that the rest supporting devices are not rotated in place exists, if the rigid contact system exists, a rotating motor is arranged on each upright or a plurality of uprights to drive the cantilever to rotate, the rigid contact system (rigid on a contact line) can gradually transmit force, and the situation that the rotation is not in place does not exist. The high-speed railway is taken in the life, what the subway looked is fixed flexible contact net, and the movable flexible contact net that this patent provided mainly is used in places such as large-scale goods yard, railway container goods handling, warehousing maintenance.

The flexible contact line is adopted between the upright posts, due to construction errors and the influence of expansion with heat and contraction with cold of the contact line and the carrier cable, the contact line is especially long-distance and even used for ten thousand tons of heavy-duty trains, and the situation that the rest supporting devices in the contact line cannot rotate in place is more obvious as the distance is longer. The patent provides a solution based on the angle to find the problem.

So to say, in this field, in such a scenario, conventionally, since the catenary and the contact wire are fixed to the support devices, when the first support device on the extreme side is rotated into position, the catenary and/or the contact wire cannot be pulled further, so that there is a case that the rest of the support devices in the catenary are not rotated into position.

This problem has existed since the day of flexible mobile catenary systems, and prior disclosures of prior art, and none have been found or found to disclose, or more particularly, provide a solution to, the problem for a time. The messenger is able to move relative to the support means; or the contact wire can be movable relative to the support means. The innovative idea itself breaks through the traditional thinking, subverts the existing fixing mode, is not a technical solution which is easy to think by the technical personnel, if the innovative idea can be easily imagined, there should be a prior technical disclosure in the early days, the prior art is supposed to be fixed on the supporting device in the field, in the prior art, after the most edge supporting device rotates in place, no technical disclosure is available to further move the carrier cable or the contact wire, the technical shortage that the rest supporting devices do not rotate in place is solved by adopting the mode, the possibility of other aspects is not considered, and therefore, the research and development of the technical field are hindered, and the technical point provided by the patent overcomes the technical prejudice.
