Description

Technical Field

[0001] The present application relates to the technical field of maintenance of power transmission equipment, and in particular to a maintenance device for cables between power towers. Background Art

[0002] Cable maintenance between power towers is an important part of ensuring the safe operation of the power grid. Traditional cable maintenance methods mainly rely on manual operations, especially in winter when there is a lot of snow, requiring workers to climb to high places for cleaning operations, which is not only inefficient but also poses a high safety hazard. In recent years, with the development of science and technology, various automation equipment has begun to be used in the maintenance of power systems, significantly improving work efficiency and safety.

[0003] The existing power tower cable maintenance equipment is mainly based on the remote control system of drones. The drones carry cleaning tools to the designated location, and the operator remotely controls the cleaning operation so that the cleaning tools move along the cables with the drone to clean the snow on the cables.

[0004] However, the existing power tower cable maintenance equipment still has some shortcomings in practical applications; especially in winter, the existing equipment has poor stability during travel and is easily deviated from the predetermined path due to external environmental factors (such as wind speed changes), affecting the cleaning effect. Therefore, there is an urgent need for a maintenance device that can stably remove snow from cables. Summary of the invention

[0005] In order to stably remove snow from cables, the present application provides a maintenance device for cables between power towers.

[0006] The present application provides a cable maintenance device between power towers that adopts the following technical solution:

[0007] A maintenance device for cables between power towers, comprising:

[0008] A traction rope, each end of which is used to be fixedly connected to an electric power tower; and

[0009] A forward driving device, the forward driving device comprising two clamping assemblies and a linear driving member connected between the two clamping assemblies;

[0010] The clamping assembly includes a traveling seat, a locking groove is formed on the traveling seat along a first direction, and in a second direction, one end of the locking groove is a groove bottom, and the other end forms a groove for the traction rope to pass through along the second direction;

[0011] A fixed mounting seat, the fixed mounting seat being fixedly connected to the walking seat; and

[0012] A locking seat, the locking seat being slidably connected to the fixed mounting seat along a second direction so that the fixed mounting seat can pass through the notch and then be inserted into the locking groove;

[0013] The driving direction of the linear drive member is parallel to the first direction, and both ends of the linear drive member are fixedly connected to one of the fixed mounting seats;

[0014] The maintenance device also includes a cleaning component for cleaning cable impurities, and the cleaning component is connected to the fixed mounting seat.

[0015] By adopting the above technical solution, the forward drive device is suspended between the power towers using a traction rope, which not only reduces the pressure of the equipment on the cable, but also realizes efficient and stable cable cleaning operations through mechanical automation. Especially in winter, the cleaning component can quickly and effectively remove snow from the cable, avoid line failures caused by snow accumulation, and improve the safety and reliability of the power system. In addition, through the design of the linear drive and the clamping component, only one of the clamping components needs to be fixed to the traction rope each time, and then the forward operation of the other clamping component on the traction rope can be realized by adjusting the length of the linear drive, so that the forward drive device can move forward stably on the traction rope, which reduces the problem of excessive shaking of the cleaning equipment due to wind force and the inability to clean the snow, and further improves the continuity and stability of the cleaning operation.

[0016] Optionally, it further comprises a lifting frame, wherein the lifting frame is connected to the fixed mounting seat;

[0017] There are a plurality of traction ropes, and the plurality of traction ropes are arranged at intervals in the third direction;

[0018] Each of the traction ropes is provided with a corresponding forward driving device;

[0019] The lifting frame is connected to a fixed mounting frame in a plurality of forward driving devices, and the cleaning assembly is connected to the lifting frame.

[0020] By adopting the above technical solution, a plurality of forward driving devices arranged side by side can simultaneously provide lifting points for the lifting frame, thereby improving the overall stability and reliability of the maintenance device.

[0021] Optionally, the lifting frame includes:

[0022] a main crossbar connected to the fixed mounting seat; and

[0023] A sliding seat, the sliding seat is freely slidable along a third direction and connected to the main cross bar;

[0024] The cleaning assembly is correspondingly arranged on each of the sliding seats.

[0025] By adopting the above technical solution, the main cross bar is connected to the fixed mounting seat, so that the lifting frame can be firmly installed on the forward driving device; the sliding seat is freely slidable along the third direction and connected to the main cross bar, so that the cleaning component can be freely adjusted on the main cross bar to adapt to cables with different spacings; a cleaning component is respectively arranged on each sliding seat, so that multiple cables can be cleaned at the same time, thereby improving work efficiency.

[0026] Optionally, the cleaning assembly includes a scraper seat, which is fixedly connected to the sliding seat, and an end of the scraper seat away from the traction rope is provided with a scraper groove for the cable to be embedded.

[0027] By adopting the above technical solution, a scraper groove for the cable to be embedded is opened at the end of the scraper seat away from the traction rope, so that the cleaning component can be stably overlapped on the cable, and the scraper seat can scrape off the snow on the cable during the forward movement.

[0028] Optionally, the cleaning component further includes:

[0029] A longitudinal cylinder having a central axis, the longitudinal cylinder is connected to the scraper seat by rotation around its own central axis, and the longitudinal cylinder is located in the scraper groove;

[0030] In the third direction, two rows of longitudinal cylinders are distributed, and the two rows of longitudinal cylinders form a clamping area in the third direction, and the clamping area is used for inserting cables.

[0031] By adopting the above technical solution, the longitudinal cylinder of the cleaning component can effectively clamp the cable, ensuring that the cleaning component stably fits the cable surface during the forward movement. The rotation design of the longitudinal cylinder reduces the friction between the cable and the cleaning component, avoiding cable damage caused by friction.

[0032] Optionally, the outer peripheral wall of the longitudinal cylinder is fixedly connected with a first flexible insulating layer.

[0033] By adopting the above technical solution, the first flexible insulating layer effectively reduces the direct contact between the longitudinal cylinder and the cable, avoiding the risk of cable damage or fire caused by friction with hard materials. At the same time, as a flexible material, the first flexible insulating layer can better adapt to the unevenness of the cable surface, improving cleaning efficiency and safety.

[0034] Optionally, a material sweeping component is further included, and the material sweeping component includes:

[0035] A mounting frame, the mounting frame is fixedly connected to the sliding seat;

[0036] a chassis, the chassis being capable of rotating along the mounting frame about a first axis, the first axis being parallel to the second direction;

[0037] A brush, wherein the brush is fixedly connected to the chassis, and when the top wall of the scraper groove of the scraper seat overlaps the cable, the brush contacts the cable; and

[0038] A driving motor is connected between the mounting frame and the chassis so that the driving motor drives the chassis to rotate around a first axis.

[0039] By adopting the above technical solution, the introduction of the sweeping component improves the cleaning efficiency of the cable surface; the design of the chassis rotating around the first axis enables the brush to effectively remove snow and other impurities during the rotation of the chassis. The use of the drive motor not only ensures the continuous rotation of the brush, but also improves the automation of the cleaning operation and reduces the need for manual intervention.

[0040] Optionally, a rotary drive assembly is further included, wherein the rotary drive assembly includes:

[0042] A first support frame, wherein the first support frame and the cam are arranged on the same cleaning assembly, and the first support frame is fixedly connected to the mounting frame;

[0043] A sliding rod, on two adjacent cleaning assemblies, one end of the sliding rod is slidably connected to the first support frame along the third direction, and the other end is fixedly connected to the mounting frame in the other cleaning assembly; one end of the sliding rod close to the cam abuts against the cam; and

[0044] an elastic member, wherein the extension direction of the elastic member is parallel to the third direction, one end of the elastic member is fixedly connected to the sliding rod, and the other end of the elastic member is fixedly connected to the first support frame;

[0045] The elastic member, in a state of being able to recover its deformation, has a force to drive the sliding rod to move along the first supporting frame toward one side of the cam.

[0046] By adopting the above technical solution, when the chassis rotates with the driving motor, the cam will rotate synchronously around the first axis; the cam will periodically push the sliding rod during the rotation, so that the sliding rod will reciprocate along the third direction on the first support frame; the reciprocating motion will cause the distance between two adjacent cleaning components to change, thereby causing the cable to vibrate slightly; this vibration helps to shake off some of the accumulated snow in advance, reduce the cleaning burden of the subsequent brush, and improve the cleaning efficiency.

[0047] Optionally, a side of the sliding rod close to the cam is fixedly connected to a limiting seat, and the limiting seat is in contact with an outer peripheral wall of the cam.

[0048] By adopting the above technical solution, the limit seat contacts the outer peripheral wall of the cam, ensuring the stable movement of the sliding rod under the action of the cam, avoiding the risk of the sliding rod being offset or falling off during the movement, and improving the working reliability of the entire maintenance device. At the same time, the limit seat also plays a role in limiting the maximum stroke of the sliding rod.

[0049] Optionally, the sliding rod is a telescopic rod with an adjustable fixed length.

[0050] By adopting the above technical solution, the length of the sliding rod can be adjusted according to actual needs to ensure that the distance between two adjacent cleaning components is appropriate, thereby better adapting to cables of different diameters and spacings. In addition, the design of the telescopic rod improves the overall flexibility and adaptability of the maintenance device, which helps to maintain a stable working state under different working conditions.

[0051] In summary, the present application includes at least one of the following beneficial technical effects:

[0052] In the present application, the forward driving device can move forward stably on the traction rope, which reduces the problem that the wind causes the cleaning equipment to shake too much and thus makes it impossible to clean the snow, and further improves the continuity and stability of the cleaning operation;

[0053] In the present application, a cleaning component is provided on each sliding seat, so that multiple cables can be cleaned at the same time, thus improving work efficiency;

[0054] The cleaning efficiency can be improved by providing a sweeping component. BRIEF DESCRIPTION OF THE DRAWINGS

A rotary drive assembly 8 is correspondingly connected between two adjacent cleaning assemblies 6. The rotary drive assembly 8 includes a cam 81, a first support frame 82, a second support frame 83, a sliding rod 84, a limit seat 85 and an elastic member 86;

[0096] In the first direction, the cam 81 is located between the chassis 74 and the mounting frame 71 , and the cam 81 is sleeved on the rotating shaft 73 and fixed to the rotating shaft 73 , so that the cam 81 can rotate synchronously with the rotating shaft 73 ;

One end of the elastic member 86 is fixedly connected to the limit seat 85, and the other end is fixedly connected to the first support frame 82. During the process of the cam 81 rotating until the protruding end abuts against the limit seat 85, the deformation of the elastic member 86 gradually increases, and accumulates force to push the limit seat 85 toward the side of the cam 81.

[0101] Reference Figure 5 and Figure 6 In some embodiments of the present application, the sliding rod 84 is a telescopic rod with adjustable length. Specifically, the sliding rod 84 has two connecting rods threadedly connected to each other, one of which is connected to the limit seat 85 by rotating around an axis, and the axis is parallel to the third direction; in the process of rotating the two connecting rods relative to each other, the fixed length of the sliding rod 84 can be changed.

[0103] The implementation principle of the cable maintenance device between power towers in the embodiment of the present application is as follows: the two ends of the traction rope 1 are fixedly connected to a power tower respectively, and then the forward driving device is placed on the traction rope 1 accordingly. Since the traction rope 1 can bear the gravity of the entire maintenance device, the pressure of the entire maintenance device on the cable 01 can be reduced;

[0104] Then, the length of the linear drive cylinder 5 is adjusted to overlap the cleaning assembly 6 onto the cable 01. Next, the length of the sliding rod 84 is adjusted so that the two adjacent cables 01 exert a squeezing force along the third direction on the sliding rod 84 between the two cables 01, that is, the two adjacent cables 01 are stretched apart, and the installation of the maintenance device is completed.

[0105] During the cleaning process, the forward driving device moves forward along the traction rope 1. During this process, the motor drives the brush 75 to rotate to sweep the snow off the cable;

[0106] At the same time, the cam 81 will rotate synchronously under the drive of the motor and continuously change the distance between two adjacent cables 01 to make the cable 01 shake, so as to shake off part of the snow on the cable 01 in advance, so that the subsequent brush 75 can clean the snow more thoroughly.

[0107] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
