Description

A fall prevention bracket for high-altitude work

technical field

The invention relates to the technical field of equipment maintenance of substations, in particular to a fall prevention bracket for high-altitude operations.

Background technique

In view of the current open substation, when overhauling the 110kV disconnector or the upper frame, the existing safety belt hook device is a single-pole hook device fixed on the channel steel at the bottom of the disconnect switch. The disadvantage is that the fixation is unreliable. During work, the back and forth of the seat belt may cause the bottom fixing device to loosen, making the seat belt lose its protective effect; Disadvantage 2: The distance between the phases of the 110kV outdoor isolating switch is large, and there is no pedal that can be stepped on during the transfer of the operating point, which greatly increases the Personnel work safety. To this end, we have developed a device that can ensure the safety of operators working at heights, so that operators can easily transfer operating points between phases, which can significantly improve the maintenance efficiency of 110kV outdoor disconnectors.

With a buckle ring (20), a connecting body (10) is welded to the long end of the rectangular frame, and the bottom of the connecting body (10) is provided with a U-shaped groove B (25), and both sides of the U-shaped groove B (25) A long hole B (26) is provided on the wall, one end of the vertical arm (2) is hinged with the connecting body (10) through the long hole B (26) by adjusting the fixing bolt B (9), and the other end of the vertical arm (2) is provided with a U-shaped Slot A (5), long holes A (4) are provided on both side walls of U-shaped groove A (5), and one end of the transverse arm (1) passes through the long hole A (4) and the The vertical arm (2) is hinged, the other end of which is vertically provided with a hook (23), a screw hole is arranged in the middle of the vertical arm (2), and one end of the screw fixing rod (7) passes through the screw hole and the anti-skid rubber base (11) Threaded connection, the other end is sleeved with a screw fixing operating rod (8), a nut (6) is arranged in the middle, and the two sides of the rectangular frame are symmetrical. The material of the seat belt buckle rod (19) is insulating material. The material of the pedal (16) is an insulating material. The seat belt buckle rod base (18) is circular or square, with a through hole in the middle. A through hole is formed in the middle of the seat belt buckle support (24).

The use method of the present invention: the device is composed of three parts: a safety belt buckle rod, a pedal and a fixing device. The seat belt buckle rod is made of epoxy resin, which is light, high strength and strong insulation performance. There are two fixing holes on the top for connecting and fixing with the seat belt buckle ring support. There is a seat belt hook on each side of the belt hook bracket, and two fixing holes are also arranged at the bottom of the seat belt hook rod, which are used for connection and fixation with the seat belt hook rod base on the pedal. Use the plug-in method. The pedal frame is made of stainless steel to reduce its weight, and the interior is made of epoxy resin, which has high strength and strong insulation performance. The steel span can be adjusted, and there is a square or round seat belt buckle rod base at the edge of the middle of the pedal. The fixing device adopts the hinged connection between the adjustable connecting body and the vertical arm, the hinged connection between the vertical arm and the transverse arm, and finally adopts the adjustable transverse arm to cooperate with the bottom edge of the channel steel. Reliable fixation between.

The beneficial effect of the invention is that: by using the anti-falling bracket for high-altitude operation, the safety belt of the operator can have a reliable hook point when the 110kV outdoor isolation switch is repaired, the safety protection will not be lost during the transfer of the operation point, and the pedal can be greatly improved. It reduces the operation safety risk of operators, facilitates the transfer of personnel to high-altitude operation points, and improves the maintenance efficiency.
