Description

Aerial working device used in high pressure work

technical field

The invention relates to a high-altitude operation device used in high-pressure work.

Background technique

At present, the pulleys and transfer ropes used to carry out live work on the conductors of 500kV transmission lines to transfer tools and materials are hung on the body of the wiring workers, and they are carried by the conductors to walk on the conductors. For 500kV transmission lines, the conductor distance The ground is relatively high, especially for double-circuit transmission lines on the same tower. The distance between the upper conductor and the ground is more than 60 meters. The swing of the rope shifts the center of gravity of the line operator, causing the body to be unstable and unsafe, which is unfavorable to the safe completion of the operation. At the same time, the line operator carries the transfer rope and walks on the wire, and the transfer rope and the wire wear each other The situation is unavoidable. The insulating rope used in live work requires high dryness and cleanliness. The grinding of the transmission rope and the wire will cause serious dirt and wear on the insulating rope, which also poses a safety hazard to the operation.

Contents of the invention

The technical problem to be solved by the present invention is to provide a high-altitude working device used in high-voltage work, which can make wiring personnel simple, convenient, safe and durable to work on power line conductors.

The present invention adopts following technical scheme:

The present invention comprises an upper pulley device, a lower pulley device and a connecting shaft connecting the upper pulley device and the lower pulley device. The upper pulley door on the body; the lower pulley device includes a left splint, a right splint, a lower pulley arranged at the lower end of the left splint and the right splint, and a connecting shaft set at the lower end of the connecting shaft at the upper end of the left splint and the right splint .

Pin holes are arranged on the door of the upper pulley bin of the present invention, and the lower end of the corresponding upper pulley bin body is provided with a rotation limiting pin.

The positive effects of the present invention are as follows:

The use of the invention avoids the problem that the center of gravity of the body of the operator is shifted due to carrying the transmission rope, causing the body to be unstable and causing unsafe factors. The transmission block is suspended on the wire, and the operator pushes forward by hand, reducing The load of the line operator improves the safety factor of the operation.

Using the present invention avoids the problem of rubbing against wires when wiring workers carry transmission ropes, reduces the replacement of insulated transmission ropes, ensures the cleanliness of insulation transmission ropes, and saves the purchase of wires under the premise of ensuring safety Insulated funds passing rope.

Detailed ways

As shown in accompanying drawing 1,2,3, the present invention comprises upper pulley device, lower pulley device and the connecting shaft 1 that connects upper pulley device and lower pulley device, and described upper pulley device includes upper pulley housing body 2, is arranged on The upper pulley 3 in the upper pulley bin body 2 and the upper pulley bin door 10 arranged on the upper pulley bin body 2, the lower end of the upper pulley bin body 2 is provided with a connecting hole, and the connecting hole is connected with the connecting shaft 1 The upper ends are connected; the lower pulley device includes a left clamping plate 4, a right clamping plate 5, a lower pulley 6 arranged at the lower ends of the left clamping plate 4 and the right clamping plate 5, and a connecting shaft 7 arranged at the upper ends of the left clamping plate 4 and the right clamping plate 5, so The above-mentioned connecting rotating shaft 7 is sleeved on connecting rotating shaft 1 lower end.

The upper pulley door 3 is provided with a pin hole 8 , and the lower end of the corresponding upper pulley body 2 is provided with a rotation limiting pin 9 . Adopting the present invention avoids hanging the transfer rope on the wire operator, but hangs the present invention and the transfer rope on the wire and the wire operator slides it out. At the same time, the lower end of the present invention is fixed to connect the rotating shaft 7, which solves the problem The problem that the rope is long and easy to twist solves the unsafe problems such as the unsteady body of the line personnel and the wear and tear of the rope. And can also utilize the present invention to be hung on wire, hang some simple tools, material, reach the place (river, swamp, mountain stream etc.) that some ground cooperating personnel can't reach.

The upper pulley device of the present invention is used to hang on the ground wire and move; the material of the upper pulley 3 is aluminum, adopts wheel groove design, small in size and light in weight.

The lower pulley device of the present invention is the lower pulley 6 used as the transmission function; the material is an insulating material, which can wear an insulating rope, and the opening of the tackle adopts a new door opening method, which reduces the weight of the tackle and has a simple structure; and the lower part of the connecting shaft 7 is designed as The universal rotation can release the twist of the transmission rope at any time.

The invention is based on the national standard GB/T18037-2000 "Technical Requirements and Design Guidelines for Live Work Tools", and the tool has passed electrical and mechanical tests to meet the technical requirements of live work.

The use of the invention avoids the problem that the center of gravity of the body of the operator is shifted due to carrying the transmission rope, causing the body to be unstable and causing unsafe factors. The transmission block is suspended on the wire, and the operator pushes forward by hand, reducing The load of the line operator improves the safety factor of the operation.

Using the present invention avoids the rubbing of the wiring workers with the wires when carrying the transmission rope, reduces the replacement of the insulation transmission rope, ensures the cleanliness of the insulation transmission rope, and saves the cost of purchasing the insulation transmission rope under the premise of ensuring safety. funds.
