The existing flying car has low efficiency and inconvenient operation, which are mainly reflected in the following three reasons:

(1) After the traditional out-of-line flying car reaches the working position, the operator needs to use the binding wire to fix the flying car on the wire. to the braking effect. However, due to the time-consuming operation process and the large range of movements of the operators, the speeding car often rolls away. The operators need to adjust the speeding car many times during the operation to maintain the best working position, resulting in serious distraction and distraction of the operators.

(2) Flying car is a necessary tool for out-of-line inspection and maintenance, and currently there is no other tool that can replace it. The traditional out-of-line flying car is made of stainless steel and weighs nearly 15 kg. It takes a long time to transfer tools up and down, and it consumes a lot of physical strength. The volume is relatively large to meet the standing needs of operators.

(3) The groove depth and groove width of the pulley groove of the traditional flying car are small. When using the flying car to go out of the wire, there will be a wire anti-vibration hammer to hinder it. When the overhead ground wire goes out, there will be a ground wire anti-vibration hammer and ground wire drainage The parallel ditch line clamp is obstructed, so when the flying car wants to reach the position of the guide and ground wire, the anti-vibration hammer must be removed before continuing to move forward. The process of returning to the original position takes a very long time, and the physical strength of the operators is very great; the process of dismantling and installing the anti-vibration hammer has a great impact on the maintenance work of the outgoing line.

Technical scheme of the present invention has overcome above-mentioned three technical defects:

After the traditional out-of-line flying car reaches the working position, it relies on the operator to fix the flying car on the wire with tying wires, so as to play a braking role. However, the flying car is not easy to control during the operation and often slips. It is necessary to adjust the flying car several times to maintain the best working position. And the brake device of the outgoing sliding chair of the present invention adopts the combination of return spring and pin, and the size of the pin matches the groove of the pulley, so that the operator can stably control the working position through the brake device.

As shown in the comparison table in Figure 6, through the comparative analysis of stainless steel pipes, iron pipes, and bridge-broken aluminum pipes, the structural material of the overall main frame of the present invention is aluminum pipes with bridge-broken bridges, which have the advantages of high toughness and light weight. The volume and weight of the overall device are reduced, and the operation is more convenient.

As shown in the comparison table in Figure 7, through the comparative analysis of polyurethane fiber pulleys, stainless steel pulleys, and cast iron pulleys, polyurethane fiber pulleys have the advantages of light material, high cost performance, and strong wear resistance. The actual installation size of the vibrating hammer, and then select the pulley corresponding to the depth and width of the groove, the passability of the present invention on the wire is greatly improved compared with the traditional flying pulley.

The invention has the advantages of exquisite structure design, light weight, easy operation, convenient suspension and removal, and the operator can reach the working position without removing the anti-vibration hammer. At the same time, the standing posture during the original operation is changed into a sitting posture, which reduces the labor of the operator. Strength, enhanced personal safety factor, shortened maintenance work time, improved work efficiency.

Using this tool to carry out operations, the problem of long time for out-of-line inspection and maintenance is easily solved. The original maintenance operation time is shortened from 81 minutes to 55 minutes, and the operation efficiency is significantly improved.

Taking the operation of repairing 20 base tower wires as an example, the cost comparison of wire replacement using the outgoing line sliding chair device (new method) of the present invention (new method) and the traditional outgoing line flying car (traditional method) is listed, as shown in the table in Figure 8.

According to the economic cost results shown in the table in Figure 8, labor costs can be saved for every 20 operations: 8000-4000=4000 yuan; power outage costs can be saved: 540-360=1.8 million yuan.

Adopt the social benefit that device of the present invention produces:

(1) The labor intensity of the operators is reduced, repeated operations are avoided, and safety is increased.

(2) It is also suitable for the maintenance of overhead transmission lines of various voltage levels. After verification, there is no auxiliary tool of the same type, which is suitable for the promotion and use of the whole network.

The implementation manners described above are only preferred embodiments of the present invention, rather than an exhaustive list of feasible implementations of the present invention. For those skilled in the art, any obvious changes made without departing from the principle and spirit of the present invention should be considered to be included in the protection scope of the claims of the present invention.
