Description

Technical Field

[0001] The utility model relates to the technical field of power maintenance, and particularly relates to a pole climbing device. Background Art

[0002] High-voltage transmission lines are one of the important facilities of the power system and are also the "arteries" of the country's infrastructure construction and social development. Their safe operation directly affects China's economic development and the establishment of infrastructure. However, due to long-term exposure to wind, sun, and natural disasters, as well as external factors such as bird damage and human sabotage, it is necessary to replace damaged high-voltage lines.

[0003] In the prior art, generally, a scissor lift or manual pole climbing method is used to raise maintenance personnel to a specified height and then perform operations. The scissor lift is generally fixed on a vehicle and realizes automatic lifting operations through the cooperation of electric drive and a scissor mechanical structure, which has the advantages of high efficiency, safety, and convenience. Manual pole climbing generally requires workers to use professional climbing tools such as footrests to assist in climbing. The design of the footrest enables workers to firmly fix on the pole tower and gradually adjust the size and position of the footrest as the climbing height increases.

[0004] In actual use, in the face of various complex terrains and obstacles that may be encountered in the maintenance of high-voltage transmission lines, such as mountains, fields, and the edges of fields, where it is inconvenient for vehicles to enter, the flexibility and adaptability of the scissor lift may be limited to a certain extent. Although manual pole climbing has a certain degree of flexibility, it has high operation difficulty, high risk, and consumes a lot of manpower. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a pole climbing device to solve the technical problem that the elevation device in the prior art cannot balance flexibility and safety.

[0006] The technical problem to be solved by the utility model can be realized through the following technical solutions:

[0007] A pole climbing device, comprising an upper locking seat and a lower locking seat longitudinally distributed on the outer side of the pole body. The upper locking seat and the lower locking seat are symmetrically arranged and both include an upper steel plate and a lower steel plate assembled together. The upper steel plate and the lower steel plate are both in a C-shaped rod shape symmetrically arranged. The end of the upper steel plate is rotationally connected to the end of the corresponding lower steel plate through a pin shaft. The pin shaft is vertically connected between the upper and lower plates of the U-shaped frame. Oil cylinder main pins are arranged on the splicing ends of the upper steel plate and the lower steel plate. A small oil cylinder is connected in cooperation between the two oil cylinder main pins. On both sides between the upper locking seat and the lower locking seat, a first lifting main oil cylinder and a second lifting main oil cylinder are respectively arranged in cooperation. A hanging basket operating platform is detachably connected to the lower steel plate located below. A total oil pump body for controlling the working states of the small oil cylinder, the first lifting main oil cylinder, and the second lifting main oil cylinder is arranged on the hanging basket operating platform;

[0008] A lifting assembly, which is arranged in cooperation between the hanging basket operating platform and the lower steel plate located at the upper end.

[0009] As a further scheme of the present invention: The lifting assembly includes a wire rope winch main machine, a pulley, and a wire rope body. The wire rope winch main machine is installed on the hanging basket operating platform. The pulley is vertically rotationally connected to the lower steel plate located above. One end of the wire rope body is wound around the wire rope winch main machine, and the other end passes through the top of the pulley and is connected with a lifting hook.

[0010] As a further scheme of the present invention: Two safety chains are detachably installed between the lower steel plate located above and the brake pads obliquely below. The two safety chains are respectively located on both sides of the pole body.

[0011] As a further scheme of the present invention: Hinge main pins are installed on the opposite surfaces of the two U-shaped frames. A first lifting main oil cylinder is installed between the two hinge main pins.

[0013] As a further scheme of the present invention: A plurality of moving wheels are distributed at the bottom of the hanging basket operating platform.

[0014] The beneficial effects of the present invention:

[0015] 1. The utility model controls the alternate clamping of the upper locking seat and the lower locking seat on the rod body by controlling the telescopic movement of the small oil cylinder. While releasing the clamping of the rod body by the locking seat, it controls the extension or contraction of the first main lifting oil cylinder and the second main lifting oil cylinder to drive the hanging basket operating platform to move up and down. This device is applicable to places where there is no access road and it is inconvenient for large cranes to operate. Moreover, this device is easy to carry, has a large working surface, and the operator can sit on the operating platform and be directly transported to the designated position, reducing the danger of manual climbing.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0022] Such as Figure 1 - Figure 2As shown in the figure, a pole climbing device includes two upper locking seats 2 and lower locking seats 3 longitudinally distributed outside the pole body 1, and a lifting assembly cooperatively arranged between the hanging basket operation platform 6 and the lower steel plate 202 at the upper end. The upper locking seat 2 and the lower locking seat 3 are symmetrically arranged, and both include an upper steel plate 201 and a lower steel plate 202 assembled together. The upper steel plate 201 and the lower steel plate 202 are both C-shaped rod-like and symmetrically arranged. The end of the upper steel plate 201 and the end of the corresponding lower steel plate 202 are rotatably connected by a pin shaft. The pin shaft is vertically connected between the upper and lower plates of the U-shaped frame 20. Oil cylinder main pins 204 are arranged on both the splicing ends of the upper steel plate 201 and the lower steel plate 202. A small oil cylinder 205 is cooperatively connected between the two oil cylinder main pins 204. The expansion and contraction of the small oil cylinder 205 can control whether the lower steel plate 202 and the upper steel plate 201 clamp the pole body 1. That is, one end of the upper steel plate 201 and the lower steel plate 202 is rotatably connected through the U-shaped frame 20, and the other end is detachably cooperatively connected with a small oil cylinder 205 through the oil cylinder main pin 204. By setting both the upper steel plate 201 and the lower steel plate 202 as C-shaped rod-like, by controlling the length of the small oil cylinder 205, the opening length of the splicing ends of the upper steel plate 201 and the lower steel plate 202 can be changed, and poles 1 with different diameters can be clamped. On both sides between the upper locking seat 2 and the lower locking seat 3, a first lifting main oil cylinder 4 and a second lifting main oil cylinder 5 are cooperatively arranged. The coordinated use of the first lifting main oil cylinder 4, the second lifting main oil cylinder 5 and the small oil cylinder 205 is used to drive the whole device to move up and down. A hanging basket operation platform 6 is detachably connected to the upper steel plate 201 at the lower part through a buckle or a bolt or other connecting components. The hanging basket operation platform 6 is used to carry staff. A total oil pump main body 601 for controlling the working states of the small oil cylinder 205, the first lifting main oil cylinder 4 and the second lifting main oil cylinder 5 is arranged on the hanging basket operation platform 6;

[0023] Clamp the upper locking seat 2 and the lower locking seat 3 longitudinally on the rod body 1. Connect the first lifting main oil cylinder 4 and the second lifting main oil cylinder 5 to both sides between the upper locking seat 2 and the lower locking seat 3 through pin shafts. Then, the staff stands on the hanging basket operation platform 6 to drive the staff to carry out work adjustment. First, control the small oil cylinder 205 on the lower locking seat 3 at the lower end to extend, releasing the clamping of the lower locking seat 3 on the rod body 1. At the same time, contract the first lifting main oil cylinder 4 and the second lifting main oil cylinder 5 to drive the lower locking seat 3 and the hanging basket operation platform 6 to move upward. Then, control the small oil cylinder 205 on the lower locking seat 3 to contract, so that the lower locking seat 3 clamps the rod body 1. Next, control the small oil cylinder 205 on the upper locking seat 2 to extend, releasing the clamping of the upper locking seat 2 on the rod body 1. Then, extend the first lifting main oil cylinder 4 and the second lifting main oil cylinder 5 simultaneously to drive the upper locking seat 2 to move upward. Subsequently, contract the small oil cylinder 205 again to make the upper locking seat 2 clamp the rod body 1. By operating in this way repeatedly, this device can drive the hanging basket operation platform 6 carrying the staff to rise. After the maintenance is completed at the designated position, it can also drive the staff to descend to the ground. This device has strong flexibility, high safety, and uses machinery instead of manual climbing, saving manpower.

[0024] In some specific implementation schemes, in order to facilitate the up and down transmission of tools or cables, the lifting assembly includes a wire rope winch main unit 602, a pulley 7, and a wire rope body 701. The wire rope winch main unit 602 is installed on the hanging basket operation platform 6. The pulley 7 is vertically rotatably connected to the lower steel plate 202 located above. One end of the wire rope body 701 is wound around the wire rope winch main unit 602, and the other end passes through the top of the pulley 7 and is connected with a lifting hook 702. When reaching the designated position, the upper locking seat 2 and the lower locking seat 3 clamp the rod body 1 simultaneously. Control the wire rope winch main unit 602 to unwind the wire rope body 701, and the lifting hook 702 drives the wire rope body 701 to extend close to the ground, facilitating the up and down transmission of the ends of tools or cables. At the same time, by setting the lifting assembly, it is also possible to avoid putting all cables or tools into the hanging basket operation platform 6, reducing the overall weight of the hanging basket operation platform 6 and lowering the probability of safety accidents.

[0025] In some specific implementation schemes, such as Figure 2 shown, in order to enhance the safety of this device, two safety chains 8 are detachably installed between the lower steel plate 202 located above and the brake pads 203 obliquely below through hooks. The two safety chains 8 are respectively located on both sides of the rod body 1. When the lower locking seat 3 is not clamped firmly, the safety chains 8 can hold the lower locking seat 3 to prevent the hanging basket operation platform 6 from driving the staff to fall.

[0026] In some specific implementation schemes, such as Figure 1As shown in the figure, to facilitate reducing the longitudinal force borne by the hinge joint between the upper steel plate 201 and the lower steel plate 202, hinge main pins 401 are installed on the opposite surfaces of the two U-shaped frames 20. A lifting main oil cylinder 1 is installed between the two hinge main pins 401. A number of through pin holes are distributed on both the upper steel plate 201 in the upper locking seat 2 and the lower steel plate 202 in the lower locking seat 3. Connecting blocks are provided at both ends of the lifting main oil cylinder 2, and corresponding pin holes are opened on the connecting blocks. The lifting main oil cylinder 2 is detachably installed between the upper steel plate 201 on the upper locking seat 2 and the lower steel plate 202 on the lower locking seat 3. Since the hanging basket operating platform 6 is fixed on the upper steel plate 201 in the lower locking seat 3, after being subjected to the gravity of the hanging basket operating platform 6, the gravity of the hanging basket operating platform 6 and the upper steel plate 201 presses on the lower steel plate 202 in the lower locking seat 3. By arranging the lifting main oil cylinder 2 between the lower steel plate 202 in the lower locking seat 3 and the upper steel plate 201 in the upper locking seat 2, it is possible to avoid excessive longitudinal force between the upper steel plate 201 and the corresponding lower steel plate 202 and reduce the service life of the equipment.

[0027] In some specific implementation schemes, to facilitate enhancing the friction force of the upper locking seat 2 and the lower locking seat 3 on the rod body 1, a number of brake pads 203 are distributed on one side of the upper steel plate 201 and the lower steel plate 202 close to the rod body 1. By setting the brake pads 203, the friction force of the upper steel plate 201 and the lower steel plate 202 on the rod body 1 is increased, so as to avoid the entire device slipping due to the gravity of the staff and cause a safety accident.

[0028] In some specific implementation schemes, as Figure 1 shown in the figure, to facilitate the movement of the hanging basket operating platform 6 on the ground, a number of moving wheels 603 are distributed at the bottom of the hanging basket operating platform 6. By pushing the hanging basket operating platform 6, the moving wheels 603 can drive the hanging basket operating platform 6 to slide, avoiding the need for staff to carry the hanging basket operating platform 6 for movement, saving manpower. On the one hand, the removed lifting main oil cylinder 1, lifting main oil cylinder 2 and other parts such as the small oil cylinder 205 can be placed in the hanging basket operating platform 6, which has a storage function.

[0029] To facilitate the understanding of this solution embodiment by those skilled in the art, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0030] During actual operation, the upper locking seat 2 and the lower locking seat 3 are longitudinally distributed and clamped on the rod body 1. The first lifting main cylinder 4 and the second lifting main cylinder 5 are connected by a pin shaft on both sides between the upper locking seat 2 and the lower locking seat 3. Then, the operator stands on the hanging basket operating platform 6 to drive the operator to adjust the work. First, control the small cylinder 205 on the lower locking seat 3 at the lower end to extend, releasing the clamping of the lower locking seat 3 on the rod body 1. At the same time, contract the first lifting main cylinder 4 and the second lifting main cylinder 5 to drive the lower locking seat 3 and the hanging basket operating platform 6 to move upward. Then, control the small cylinder 205 on the lower locking seat 3 to contract, so that the lower locking seat 3 clamps the rod body 1. Next, control the small cylinder 205 on the upper locking seat 2 to extend, releasing the clamping of the upper locking seat 2 on the rod body 1. Then, simultaneously extend the first lifting main cylinder 4 and the second lifting main cylinder 5 to drive the upper locking seat 2 to move upward. Subsequently, contract the small cylinder 205 again, so that the upper locking seat 2 clamps the rod body 1. By repeating such operations, this device can drive the hanging basket operating platform 6 carrying the operator to rise. After the maintenance is completed at the designated position, it can also drive the operator to descend to the ground. This device has strong flexibility and high safety, and uses machinery to replace manual climbing, saving manpower. Control the wire rope winch main machine 602 to unwind the wire rope body 701, and the lifting hook 702 drives the wire rope body 701 to extend close to the ground, facilitating the up and down transmission of tools or cable ends.

[0031] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
