Description

Technical Field

[0001] The invention relates to the field of switch cabinet safety protection, and in particular to a cabinet top operation safety protection device for a center-mounted switch cabinet. Background Art

[0002] There is a lot of work on the top of the center-mounted switchgear, and the top of the cabinet is very high. Workers are prone to falling accidents when performing maintenance. There is usually no special safety belt hanging point on the top of the switchgear, which makes it difficult for workers to use safety belts effectively when working at heights, increasing the risk of falling. When working at heights, tools or other items may fall accidentally, which may not only injure ground workers, but also damage equipment.

[0003] For example, a Chinese patent with publication number CN217339844U discloses a fall protection device for working on the top of a high-voltage switch cabinet, comprising a waist belt, a first adjustment buckle, a leg strap, a second adjustment buckle, a chest strap, a protective shoulder strap, a back strap and a protective binding. The waist belt is provided with a first adjustment buckle for adjusting the tightness, and the lower end of the waist belt is connected to the leg strap, and the second adjustment buckle is provided on the leg strap. The upper end of the waist belt is provided with a chest strap, and the side of the chest strap is connected to the protective shoulder strap. It also includes: a buffer structure provided at the end of the protective binding, and a hook provided at the upper end of the buffer structure; a limit belt provided at the side of the first adjustment buckle, and the limit belt is fixedly provided at the side of the waist belt. The fall protection device for working on the top of a high-voltage switch cabinet can conveniently carry the tools needed for maintenance during maintenance, and can also play a certain buffering and protective role after a fall occurs.

[0004] However, there are still certain problems in the above documents and the prior art, so the problem to be solved by the present invention is:

[0005] 1. When the staff climbs onto the top of the cabinet to work, they need to temporarily move the small busbar away, and there is a risk of accidental falling when passing tools or other items from the bottom of the cabinet to the top of the cabinet;

[0006] 2. The staff climbed onto the top of the cabinet to work, but there was a problem that the safety belt could not be hung up, and hanging it low and using it high would not provide any protection.

[0007] 3. The Chinese patent with publication number CN217339844U states that protecting the safety of the staff must solve the problem in essence. Relying solely on a fall protection device cannot fully guarantee the safety of the staff when working on the cabinet top. Therefore, the most promising solution is to provide a device for hanging a safety belt on the cabinet top. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a centrally mounted switch cabinet top operation safety protection device to solve the above-mentioned problems.

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0010] A safety protection device for top operation of a centrally mounted switch cabinet comprises a clamp A, a clamp B, a metal rod, a hanging ring and a limiting mechanism. The clamp A is arranged at one end of the metal rod, the clamp B is connected with the limiting mechanism, the clamp A and the clamp B are connected through the metal rod, and the hanging ring is arranged at one end of the metal rod.

[0011] Preferably, the limiting mechanism is a spring lock.

[0012] Preferably, the limiting mechanism is provided with a plurality of limiting holes.

[0013] Preferably, the limiting mechanism is provided with three limiting holes.

[0014] Preferably, the clamp B is clamped into the limiting hole.

[0015] Preferably, the fixture B and the limiting mechanism are both positionably connected.

[0016] Preferably, the limiting mechanism is arranged at the middle position of the metal rod.

[0017] Preferably, both the fixture A and the fixture B are provided with nested slots.

[0018] Preferably, the nested slot of the fixture A is provided with a bolt fixing hole.

[0019] Preferably, the nested slot of the fixture B is provided with a bolt fixing hole.

[0020] Compared with the prior art, the beneficial effect of the present invention is that: a central switch cabinet top operation safety protection device includes a clamp A, a clamp B, a metal rod, a hanging ring, and a limit mechanism, which are used in combination with each other to play a role.

[0021] 1. The present invention can add a lifting device, and the small busbar and the tool platform can be lifted up according to work needs, so that the staff can work on the top of the cabinet.

[0022] 2. The present invention solves the problem that the safety belt cannot be hung when the personnel work on the top of the cabinet. Two metal rods are arranged on the diagonal of the switch cabinet, and a steel wire rope is installed between the hanging rings of the two metal rods. The safety belt can be hung on the steel wire rope to ensure the safety of the personnel working on the top of the cabinet. BRIEF DESCRIPTION OF THE DRAWINGS
