Insulation cable climbing device for hot-line work

Abstract

The invention relates to an insulation cable climbing device for hot-line work. The insulation cable climbing device for the hot-line work comprises two pulley supports and pulley hooks; the pulley hooks comprise front plates, rear plates, connecting plates and first pulley mechanisms; the first pulley mechanisms comprise rope pulling pulleys, first bearings, and first bearing mounting structures;and the first bearing mounting structures comprise first bearing storing cavities and first compressed springs, the lower ends of the first compressed springs and outer rings of the first bearings are fixed for connecting the first bearings, the first bearing storing cavities are provided with first guide seams, the upper portions of the first guide seams are provided with first rotation stoppinggrooves, and the parts, corresponding to the first rotation stopping grooves in position, of rope pulling pulley shafts are provided with first rotation stopping parts matched with the first rotationstopping grooves. The insulation cable climbing device for the hot-line work has the beneficial effects that according to requirements, compressed springs with suitable length and elastic force are selected, and when the pulley hooks are hung over cables and ladder heads are not hung, the rope pulling pulley shafts are located above the rotation stopping grooves, namely in the first guide seams,and at this time, the pulley hooks are moved to proper positions on the cables according to requirements; and when the ladder heads are pulled upwards through pulling ropes, the first compressed springs are compressed, the first rotation stopping parts are upwards clamped into the first rotation stopping grooves, the rope pulling pulley shafts no longer rotate, the rope pulling pulleys, overlapping on the cables, of the pulley hooks stop rotating, the rope pulling pulleys no longer move, and the ladder heads are conveniently pulled to required cable positions.

Description

technical field [0001] The invention belongs to the field of electric equipment, in particular to an insulating wire climber for live work. Background technique [0002] Chinese patent document ZL201320806144.7 discloses an insulating hanger for live work, including a ladder head and a soft ladder. At both ends of the fixed cross bar, the movable cross bar is located under the fixed cross bar, and the two ends of the fixed cross bar are respectively set on two pulley brackets. The movable cross bar is connected with the fixed cross bar through a spring, and the pulley hook is located on the fixed cross bar. Above, one end of the stay rope is fixed in the center of the movable cross bar, and the other end of the stay rope passes through the fixed cross bar and the pulley hook successively, and the stay rope can drive the movable cross bar to move. The top of the pulley bracket is provided with a cable pulley, and the bottom of the cable pulley is provided with a self-locking...

Problems solved by technology

[0004] Second, in the process of hanging the ladder head to the cable through the pulley hook, due to the adjustment of the ladder head posture and the force generated by the pull, the slope generated by the cable itself sags, resulting in the pulley hook being unable to position on the cable, often waiting for the ladder When the head reaches the position of the cable, it is not the desired position, and it needs to be adjusted continuously, which is very time-consuming and laborious, which greatly affects the work efficiency

[0006] Third, the process of hanging the ladder head on the cable is very difficult. The reason is that in actual operation, it is very difficult to fix the pull rope just in the middle of the movable cross bar, which makes the ladder head easy to tilt left and right. In the absence of a suitable fixed structure in the front and rear directions, the ladder head is prone to pitching and swinging. During the lifting process, the ladder head will rotate under the action of the torque release of the pull rope itself, resulting in the ladder head not being able to rise to the expected position at all. At the cable, even if you are lucky enough to reach the bottom of the cable, but because the connecting rod above the cable pulley is set horizontally, the result is that the connecting rod withstands the cable and cannot continue to rise
