Abstract
Description
Technical Field
[0001] The invention relates to the technical field of aerial work equipment for power transmission lines, in particular to a single-line obstacle-crossing flying vehicle for power transmission lines. Background Art
[0002] At present, the flying car used for transmission single-line line operation does not have the obstacle crossing function. There are safety hazards and low efficiency problems when high-altitude workers work on the wires during transmission line outgoing operations.
[0003] When the staff enters the flying car to start working, it is inevitable to cross the shock-proof hammer and the suspension wire clamp. The operator also needs to take off the flying car and rely on the safety belt, backup protection rope and wire to complete the task of leaving the flying car, so that the flying car can release force and facilitate the subsequent flying car to cross the shock-proof hammer and the straight insulator suspension wire clamp of the wire. The personnel then repeat the steps of getting on the flying car to complete an obstacle crossing. The process is cumbersome and difficult to operate, which consumes the physical strength of the operators, has great safety hazards and low efficiency. Therefore, the applicant recently applied for a single-line obstacle-crossing flying car tool for power transmission lines, application number: 202311153806X, which includes a flying car body; the flying car body includes at least three pulley routing mechanisms, the pulley routing mechanisms straddle the transmission line, and when crossing obstacles, the pulley routing mechanisms cross obstacles one by one in sequence; the two ends of the pulley routing mechanism are respectively connected to the arc frame and the wire anti-drop rod, and the other ends of the arc frame and the wire anti-drop rod are connected to the load-bearing frame through the wire anti-drop shaft bolt, and this end of the wire anti-drop rod is rotatable compared to the arc frame; the pulley routing mechanism is connected to the arc frame through the rotating shaft bolt, and the arc frame head also has a limiting track, and the bottom of the pulley routing mechanism is provided with a limiting pin and a limiting hole, and the limiting pin is inserted into the limiting track and the limiting hole, and the limiting connection between the arc frame and the pulley routing mechanism is realized in cooperation with the rotating shaft bolt. During use, the applicant of this mechanism found that it has the following disadvantages: First, the connecting pin between the wire anti-slip rod and the pulley frame is cumbersome to install and remove, and it is necessary to accurately align the through hole between the wire anti-slip rod and the pulley frame to operate the connecting pin, which is difficult for the operator. In addition, there is a risk of losing the connecting pin after it is removed, which brings a greater risk to the operator. Second, the limit pin in this patent needs to move up and down in the limit hole. Due to the upward pulling force of the pulley, the limit pin will be stuck in the limit hole, so it is not able to move smoothly in the limit hole, and it is difficult for the operator to operate each time. Third, the structure is relatively complicated as a whole. For example, a limit track needs to be processed in the arc-shaped frame, and the processing cost is high. Summary of the invention
[0004] The purpose of the present invention is to overcome the shortcomings of the above-mentioned technology and provide a single-line obstacle climbing vehicle for a power transmission line.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a single-line obstacle climbing vehicle for a power transmission line, comprising a T-shaped main structure, a folding waist guard and a fixed pulley block, wherein the folding waist guard is connected to the T-shaped main structure through a waist guard connector, the fixed pulley block comprises at least three sets, which are sequentially installed on the top of the T-shaped main structure, the fixed pulley block comprises a pulley, an L-shaped bracket, an upper arc-shaped connecting frame, a lower arc-shaped connecting frame and a locking handle, both ends of the pulley are installed on the upper arc-shaped connecting frame through the L-shaped bracket, one end of the upper arc-shaped connecting frame is hinged to one end of the lower arc-shaped connecting frame, the other end of the upper arc-shaped connecting frame has an arc notch, the locking handle is hinged to the other end of the lower arc-shaped connecting frame, one end of the locking handle is installed with a handle locking shaft, and the handle locking shaft cooperates with the arc notch. Compared with the existing structure, this device only needs a locking handle to operate. Compared with the existing connecting pin plug-in work, this structure is more convenient to operate. At the same time, it eliminates the limit rails, limit pins, limit holes and other structures in the existing structure, which is easier to process as a whole and reduces the processing cost.
[0006] Preferably, the other end of the lower arc-shaped connecting frame is fixed with a first connecting piece, the upper part of the first connecting piece is provided with an arc-shaped limiting groove, the other end of the upper arc-shaped connecting frame is plugged into the arc-shaped limiting groove, and the locking handle is hinged on the first connecting piece. The locking handle is directly fixed on the first connecting piece first, and then the first connecting piece is fixed on the lower arc-shaped connecting frame, which makes the overall processing easier.
[0007] Preferably, a second connecting piece is fixed to one end of the lower arc-shaped connecting frame, and the second connecting piece is hinged to one end of the upper arc-shaped connecting frame. Similarly, the second connecting piece can make the overall processing easier.
[0008] Preferably, the lower arc-shaped connecting frame is welded to the T-shaped main structure. The lower arc-shaped connecting frame is directly welded to the T-shaped main structure, instead of welding the arc-shaped frame to the main structure like the existing structure. The structure is more stable as a whole and the force is more uniform.
[0009] Preferably, a positioning piece is welded between the bottom of the lower arc-shaped connecting frame and the T-shaped main body structure.

The pulley can be disengaged by locking the handle. The handle is locked after crossing the obstacle, and the operating efficiency is at least doubled. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings and preferred embodiments. Figure 2-4As shown, a single-line obstacle climbing vehicle for a power transmission line comprises a T-shaped main structure 1, a folding waist guard 2 and a fixed pulley block 4. The folding waist guard is connected to the T-shaped main structure through a waist guard connector 3. The fixed pulley block is at least three sets, which are sequentially installed on the top of the T-shaped main structure. The fixed pulley block comprises a pulley 4, a shaft 6, a bearing 7, an L-shaped bracket 8, an upper arc-shaped connecting frame 18, a lower arc-shaped connecting frame 19 and a locking handle 10. The two ends of the pulley are installed on the upper arc-shaped connecting frame 19 through the L-shaped bracket. On the arc-shaped connecting frame, one end of the upper arc-shaped connecting frame is hinged to one end of the lower arc-shaped connecting frame, and the other end of the upper arc-shaped connecting frame has an arc notch 9. The locking handle is hinged to the other end of the lower arc-shaped connecting frame. There are two ways to connect the locking handle in this device. One is to directly hinge on the lower arc-shaped connecting frame like this, and the other is to install it on the lower arc-shaped connecting frame through a first connecting member. The first way requires processing a baffle plate on the upper part of the lower arc-shaped connecting frame to block the upper arc-shaped connecting frame. A handle locking shaft 11 is installed at one end of the locking handle, and the handle locking shaft cooperates with the arc notch. When the handle is locked, the handle locking shaft enters the arc notch and locks. This device adopts 3 groups of fixed pulleys to realize the obstacle crossing function, and uses the 3 groups of fixed pulleys to bear force in turns. When the first group of fixed pulleys moves forward and encounters an obstacle (suspension wire clamp, anti-vibration hammer 15), the handle is disengaged to achieve the effect that the pulley can be detached, and the handle is locked after crossing the obstacle; similarly, when the second group of fixed pulleys moves forward and encounters an obstacle (suspension wire clamp, anti-vibration hammer), the handle is disengaged to achieve the effect that the pulley can be detached, and the handle is locked after crossing the obstacle; when the third group of fixed pulleys moves forward and encounters an obstacle (suspension wire clamp, anti-vibration hammer), the handle is disengaged to achieve the effect that the pulley can be detached, and the handle is locked after crossing the obstacle. Compared with the existing structure, this device only needs one locking handle to operate. Compared with the existing connection pin plug-in work, this structure is more convenient to operate. At the same time, it omits the limit track, limit pin and limit hole structures in the existing structure, which is easier to process as a whole and reduces the processing cost.
[0018] Furthermore, in order to facilitate processing, a first connecting member 12 is fixed to the other end of the lower arc-shaped connecting frame, and an arc-shaped limiting groove is provided on the upper part of the first connecting member. The other end of the upper arc-shaped connecting frame is plugged into the arc-shaped limiting groove to cooperate with the locking handle to be hinged on the first connecting member. The locking handle is directly fixed to the first connecting member first and then the first connecting member is fixed to the lower arc-shaped connecting frame, which makes the overall processing easier. A second connecting member 13 is fixed to one end of the lower arc-shaped connecting frame, and the second connecting member is hinged to one end of the upper arc-shaped connecting frame. Similarly, the provision of the second connecting member can make the overall processing easier.
[0019] Furthermore, the lower arc-shaped connecting frame is welded to the T-shaped main structure. The lower arc-shaped connecting frame is directly welded to the T-shaped main structure, instead of welding the arc frame to the main structure like the existing structure. The structure is more stable as a whole and the force is more uniform. Furthermore, in order to make the connection between the lower arc-shaped connecting frame and the T-shaped main structure more firmly, a positioning piece 14 is welded between the bottom of the lower arc-shaped connecting frame and the T-shaped main structure.
[0020] When in use, the foldable waist protector is opened when working and fixed with the waist protector connector, and folded when not working. When the first fixed pulley block meets the shockproof hammer 15 and the straight insulator clamp 16 obstacles when moving forward, the locking handle 10 is opened, and the other two fixed pulley blocks 4 slide on the wire under force. After crossing the obstacles, the locking handle 10 is pressed down, and the handle locking shaft 11 automatically enters the arc groove 9 to lock. Similarly, when the second fixed pulley block 4 meets the shockproof hammer 15 and the straight insulator clamp 16 obstacles, the locking handle 10 is opened, and the other two fixed pulley blocks 4 slide on the wire under force. After crossing the obstacles, the locking handle 10 is pressed down, and the handle locking shaft 11 automatically enters the arc groove 9) to lock. The same applies to the third group. The design structure is reasonable. It is a flying car tool that can cross obstacles. It solves the problem that the flying car passes over the anti-vibration hammer of the conductor and the suspension clamp of the straight insulator, avoiding the personnel to repeat the steps of getting on the flying car and completing the obstacle crossing once. It solves the safety hazards and low efficiency problems of high-altitude workers working on the conductor during the transmission line outgoing operation.
[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
