Description

Technical Field

[0001] The invention relates to the technical field of substation equipment maintenance, and in particular to a high-altitude operation anti-falling bracket. Background Art

[0002] For the current open substation, when inspecting 110kV disconnectors or working on the upper structure, the existing safety belt buckle device is a single-pole buckle device fixed to the bottom channel steel of the disconnector. Its disadvantages are: unreliable fixation. The swinging of the safety belt during work may cause the bottom fixing device to loosen, making the safety belt lose its protective function; disadvantage: the phase-to-phase distance of the 110kV outdoor disconnector is large, and there is no pedal to step on during the transfer of the work point, which greatly increases the safety of the work. To this end, we have developed a device that can ensure the safety of the workers at high altitudes and allow the workers to conveniently transfer the work point between phases, which can significantly improve the maintenance efficiency of the 110kV outdoor disconnector. Summary of the invention

The end of the rectangular frame in the longitudinal direction is welded with a connector (10), the bottom of the connector (10) is provided with a U-shaped groove B (25), and the two side walls of the U-shaped groove B (25) are provided with long holes B (26), one end of the vertical arm (2) is hinged to the connector (10) by passing through the long hole B (26) through the adjusting fixing bolt B (9), and the other end thereof is provided with a U-shaped groove A (5), and the two side walls of the U-shaped groove A (5) are provided with long holes A (4), one end of the horizontal arm (1) is hinged to the vertical arm (2) by passing through the long hole A (4) through the adjusting fixing bolt A (3), and the other end thereof is vertically provided with a hook (23), a screw hole is provided in the middle of the vertical arm (2), one end of the spiral fixing rod (7) passes through the screw hole and is threadedly connected to the anti-slip rubber base (11), and the other end is sleeved with a spiral fixing operating rod (8), and a nut (6) is provided in the middle, and the two sides of the rectangular frame are symmetrical. The material of the safety belt hanging buckle rod (19) is insulating material. The pedal (16) is made of insulating material. The seat belt buckle rod base (18) is circular or square, with a through hole in the middle. The seat belt buckle ring support (24) has a through hole in the middle.

[0004] The method of using the present invention is as follows: the device is composed of three parts: a safety belt buckle rod, a pedal and a fixing device. The safety belt buckle rod is made of epoxy resin, which is light, high in strength and strong in insulation. Two fixing holes are provided on the top of the rod for connection and fixing with the safety belt buckle ring support, and a latch is adopted. A safety belt buckle ring is provided on each side of the safety belt buckle ring support. Two fixing holes are also provided at the bottom of the safety belt buckle rod for connection and fixing with the safety belt buckle rod base on the pedal, and a latch is adopted. The pedal frame is made of stainless steel to reduce its weight, and the interior is made of epoxy resin, which is high in strength and strong in insulation. Connectors connected to the fixing device are provided at both ends of the pedal, and long holes are provided on the connector, which can be adjusted according to different channel steel spans. A square or round safety belt buckle rod base of the safety belt buckle rod is provided at the edge of the middle of the pedal. The fixing device adopts the hinge connection between the adjustable connector and the vertical arm, the hinge connection between the vertical arm and the horizontal arm, and finally the adjustable horizontal arm is matched with the bottom edge of the channel steel, and the fixing device and the channel steel are reliably fixed by the spiral fixing rod.
