The folding seat includes a rotating triangular bracket and a backrest crossbar, and the two rotating triangular brackets are correspondingly connected to the hinges, and the two ends of the backrest crossbar are correspondingly fixed on two vertical bars.

The backrest cross bar is located at the lower position of the topmost cross bar of the ladder.

Compared with the prior art, the utility model has the beneficial effect that: the three pulleys in the utility model are installed and designed through an equilateral triangle. Each plane and vertex of the triangle has a length of 40 cm. It is just the distance between the upper and lower split lines of 220kV, and the upper and lower split lines can be fixed at the same time. It is not only convenient for on-line and off-line operations, but also increases the stability. When the operator is operating at the wire operation point. The cross section can be separated by the hinge part, and a 20cm wide platform is formed by the triangular 90-degree rotating support. The operator can sit on the platform to work, which greatly reduces the physical exertion of the operator.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is described further.

Fig. 1 is the structural representation of the utility model.

Among the figure: 1 is a pulley block, 2 is a ladder, 21 is a vertical bar, 22 is a cross bar, 3 is a folding seat, 31 is a rotating triangular support, 32 is a backrest cross bar, and 4 is a hinge.

Detailed ways

As shown in Figure 1, the utility model is a multifunctional live work ladder head, comprising a pulley block 1, a ladder 2 and a folding seat 3, the pulley block 1 is a triangular structure composed of three pulleys, the upper end of the pulley block 1 The pulleys are matched to ride on the upper split line, the two pulleys at the lower end of the pulley block 1 are matched to ride on the lower split line, the upper end of the ladder 2 is correspondingly connected to the lower side of the pulley block 1, and the ladder 2 includes vertical bars on both sides 21 and a plurality of cross bars 22 in the middle, the cross bars 22 are square bars, and a plurality of the cross bars 22 are arranged in parallel and equidistant between two vertical bars 21, and the foldable seat 3 passes two A hinge 4 is movably arranged on the top cross bar 22 of the ladder 2, and can rotate 90° around the cross bar 22, so that maintenance personnel can sit on the folding seat 3 with a sitting posture.

The foldable seat 3 includes a rotating triangular bracket 31 and a backrest cross bar 32, and the two rotating triangular brackets 31 are correspondingly connected to the hinge 4, and the two ends of the backrest cross bar 32 are correspondingly fixed on two On the vertical bar 21.

The backrest cross bar 32 is located at the lower position of the topmost cross bar 22 of the ladder 2 .

The utility model serves as a live working ladder head which is safe, comfortable and improves working efficiency. Including: three pulley brackets, fixed cross bar, backed by round steel, changed the round tube of the cross bar to square epoxy resin to increase the friction force and the force bearing area of the sole of the foot, and installed a seat device on the square pedal.

Working principle of the present utility model: when in use, when 110KV live electricity and power failure work, just can operate by hanging the pulley block 1 on the wire. During 220KV electrification and power failure operation, the upper end pulley of pulley block 1 is hung on the upper split line, and the lower two pulleys are hung on the lower split line to operate. Change the original horizontal circular tube to a 10 cm wide square epoxy resin to increase the friction force and the force-bearing area of the sole of the foot. The force-bearing tripod support frame can rotate 90 degrees to form a 20-centimeter platform that can be used for workers to sit on.

The working process of the utility model: after the operator boards the pole tower, an operator hangs a transmission rope with a pulley on the overhead line above the conductor. Pull the connected ladder head and the rope ladder to a place parallel to the wires by the personnel below through the transfer rope.
