Bicycle for aloft work

Abstract

The invention discloses a bicycle for aloft work. The bicycle comprises a main beam. The front side and the rear side of the main beam are correspondingly connected with a front supporting arm and a rear supporting arm. A foot stepping wheel disc is arranged at the joint of the main beam and the front supporting arm. A front hook is arranged at the upper end of the front supporting arm. A front idler wheel which is in chain transmission with the foot stepping wheel disc is arranged in the front hook. A safety handle is arranged in the middle of the front supporting arm. A rear hook is arranged at the upper end of the rear supporting arm. A driven rear idler wheel is arranged in the rear hook. The hook opening of the front hook is provided with a safety lock. The hook opening of the rear hook is provided with a safety lock. A hook body of the front hook is connected with an auxiliary brake device which comprises a connecting plate connected with the hook body, wherein a brake block is hinged to the connecting plate, the two sides of the brake block on the connecting plate are correspondingly provided with a first limiting block and a second limiting block, and a compression spring which keeps the brake block in the first position or the second position is connected between the middle of the brake block and the connecting plate. The bicycle has the advantages of being reasonable in structure, stable in riding and high in safety coefficient.

Description

technical field [0001] The invention relates to an auxiliary tool for power transmission lines, in particular to a high-altitude operation bicycle used on a single power transmission line. Background technique [0002] A lot of work on the high-altitude ground wire of the transmission line, such as replacing the anti-vibration device, installing spacers, repairing the ground wire, etc., can only be completed by going out (sliding along the ground wire to the direction away from the transmission tower). It may be a few meters, a dozen meters, or even tens of meters. [0003] At present, cranes are generally used for outgoing operations. One side of the two ladder rods is provided with an outstretched blue rod for the operator to sit temporarily. The top of the ladder rod is provided with a pulley. The operator uses the hand to pull the ground wire to drive the pulley to slide. Move, so as to drive itself forward or backward. [0004] There are obvious shortcomings in the us...

AI Technical Summary

Problems solved by technology

However, the body of the operator is on one side of the ground wire, which will inevitably cause the body to tilt, which will bring great inconvenience to the operation and movement, and even cause the danger of "overturning"

So this requires at least two ground personnel to use ropes to tighten the lower end of the gondola at all times to keep it as vertical as possible, but there will still be a certain inclination angle

Moreover, the ground personnel need to choose the location according to the ground conditions. If there are rivers, trees, etc. under the conductor, it will be difficult to carry out the operation.

[0006] Furthermore, the movement of the people-ladder combination depends entirely on the operator to guide the ground wire by hand. In the case of a long distance from the line or a large height difference, the operator consumes a lot of physical strength when going back, and sometimes it is difficult to return when exhausted.

[0007] In addition, the pulley of the hanging basket itself does not have a braking device. When the operator slides down, he basically relies on both hands to hold the wire tightly to brake. The speed is difficult to control and there is danger.
