Problems solved by technology

The environment on the top of the electric high-voltage switchgear is complicated, and the surface of the top of the cabinet is uneven, which can easily cause workers to fall and trip. The most important thing is that there is no reliable suspension point for safety belts on the top of the switchgear. In this case without reliable safety belt protection, Workers working on the top of the cabinet are prone to fall accidents from heights, which may cause personal injuries in the slightest, and cause disability or even death in severe cases;

Embodiment 1

[0035] The present invention is a safety belt hanger for high-altitude operations, including a steel wire rope 11 and a controller 12, the steel wire rope 11 is provided with a safety belt hook 13, and the safety belt hook 13 can slide back and forth on the steel wire rope 11, Both sides of the steel wire rope 11 are provided with a tensioning mechanism 2, and the tensioning mechanism 2 can tighten the steel wire rope 11. The other side of the tensioning mechanism 2 is provided with a U-shaped fixing frame 3, and the U-shaped fixing frame 3 Steel plate stamping is adopted, and fastening bolts 4 are threaded on the outer wall of the U-shaped fixing frame 3, and the whole device can be suspended between the two walls through the U-shaped fixing frame 3, and the fastening bolts 4 are screwed The U-shaped fixing frame 3 is fixed to the wall to prevent the device from falling off from the wall. The tensioning mechanism 2 can tighten the fixed steel wire rope 11 so that the steel wir...

Embodiment 2

[0040] The present invention is a safety belt hanger for high-altitude operations. On the basis of Embodiment 1, a second support frame 51 is provided on the side of the U-shaped fixed frame 3, and the outer wall of the second support frame 51 is A motor 52 is provided, and the motor 52 is connected with the controller 12. The output end of the motor 52 is provided with a first bevel gear 53, and the second support frame 51 is provided with a rotating shaft 54, and the rotating shaft 54 ​​is connected to the wire rope 11 connected, the outside of the shaft 54 ​​is provided with a second bevel gear 55, the second bevel gear 55 meshes with the first bevel gear 53, and the motor 52 drives the first bevel gear 53 to rotate, thereby driving the second bevel gear 55 to rotate , so that the rotating shaft 54 ​​can roll up the wire rope 11, and control the rotation of the motor 52 by the controller 12, so as to tighten the wire rope 11, further ensure the effect of the tension mechanis...

Embodiment 3

[0043] The present invention is a safety belt hanger for high-altitude operations. On the basis of Embodiment 1, a first support frame 71 and an electric cylinder 72 are provided on the side wall of the U-shaped fixed frame 3. The first support The frame 71 is rotatably connected with a swing rod 73, the upper part of the swing rod 73 is provided with a fixed claw 74, the elongated end of the electric cylinder 72 is in contact with the swing rod 73, and the inner wall of the U-shaped fixed frame 3 is provided with a pressure The sensor 75, the outside of the pressure sensor 75 and the electric cylinder 72 are all connected to the controller 12, and the pressure sensor 75 can measure the pressure between the U-shaped fixing bracket 3 and the wall. In the case where the steel wire rope 11 has a tendency to take the U-shaped fixing frame 3 away from the wall, when the pressure value between the pressure sensor 75 and the wall is small, the controller 12 starts the electric cylinde...

Abstract

The invention discloses a safety belt hanger for working at heights, and relates to the technical field of electric safety protection devices. Including a steel wire rope and a controller, the steel wire rope is provided with a safety belt hook, the two sides of the steel wire rope are provided with a tensioning mechanism, the other side of the tensioning mechanism is provided with a U-shaped fixing frame, and the outer wall of the U-shaped fixing frame A fastening bolt is threaded, and the tensioning mechanism includes a first threaded bar, a second threaded bar and a tensioning ring, one end of the first threaded bar is fixedly connected to the steel wire rope, and the other end of the first threaded bar is connected to the tensioning ring. The ring is threaded, one end of the second threaded strip is threaded with the tensioning ring, and the other end of the first threaded strip is connected with the U-shaped fixing frame. The beneficial effect of the present invention is that: the safety belt hanger with a corresponding distance can be installed according to the site environment, which ensures the operation safety of the maintenance personnel and improves the maintenance efficiency.

Description

technical field [0001] The invention relates to the technical field of electric safety protection devices, in particular to a safety belt hanger for working at heights. Background technique [0002] Power high-voltage switchgear is a common high-voltage electrical equipment in substations. It plays the role of on-off power lines, and the number of bases is large. For different jurisdictions, the number of management is different, up to thousands, to ensure The safe and reliable operation of the equipment and the safe and reliable use of electricity by users require substation maintenance personnel to carry out regular maintenance and test work on them, and this kind of work includes some work that requires operators to climb to the top of the switch cabinet; [0003] The height of electric high-voltage switchgear is usually 2.5 meters to 2.8 meters. The national standard GB3608-93 "Classification of Working at Heights" stipulates: "Any operation at a height where the fall he...
