Abstract
The invention discloses a locating locking fixture for preventing upper and lower static contact baffles in a switch cabinet from being opened, which is characterized in that the fixture is provided with a rotary stopping handle comprising an insulated handle (1) and a handle screw (2). The handle screw (2) is movably connected with a locating rod (8) which is provided with a locating tube (3). Two opposite cutting sleeve adjusting screws (5) are inserted in the locating tube (3), wherein one cutting sleeve adjusting screw (5) is sleeved with a spring (7) and the other cutting sleeve adjusting screw (5) is provided with a stopping pin (6). Each cutting sleeve adjusting screw (5) is connected with an adjusted cutting sleeve (4). An adjusting screw (10) is movably connected at the front end of the locating rod (8). The fixture is simple in structure, safe and reliable, is suitable for different kinds of 10kV and 35kV intermediate type switch cabinets, can realize preventing upper and lower static contact baffles in the switch cabinet from being opened, prevent the dangerous points in the work and ensure the safety of the workers.
Description
Technical field:
The present invention relates to a kind of locking fixture, relate in particular to a kind of locating locking fixture that prevents that upper and lower static contact baffles in switch cabinet from opening.
Background technology:
In recent years, advantages such as the mid-cabinet-type switch cabinet of 10kV, 35KV is little because of its structural volume in operation of power networks, speed is fast, drop-out current is big are widely used, but maintenance in switch cabinet, disappearing often can not guarantee reliable safety measure when lacking, bring potential safety hazard to the maintainer, in the scarce work of overhauling, disappear in the intermediate switchgear cabinet cabinet in the past, the safety measure of being made is an installing red cloth curtain on upper and lower static contact baffles; The 2nd, place " in this work " indication plate in the working site; The 3rd, the special messenger guards.These three safety measures all can not prevent the unlatching of upper and lower static contact baffles fully in real work, after circuit breaker is drawn out of, because the defective of push-pull mechanism, static contact baffles is easily opened by mistake, cause high-voltage contact exposed, thereby make the maintainer that the possibility of electric shock be arranged, cause great human casualty accident.The staff once just being taken place in the service work, open by mistake and open upper and lower static contact baffles in the intermediate switchgear cabinet cabinet, caused the dead major accident of the person.In order fundamentally to stop the generation of similar painful accident, be badly in need of a kind of instrument that prevents that upper and lower static contact baffles is opened in the intermediate switchgear cabinet cabinet of development, " dangerous spot " at control operation scene fundamentally guarantees maintainer's personal safety, avoids the generation of similar painful accident effectively.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of simple in structure, safe and reliable, regulate flexibly, install the firm locating locking fixture that upper and lower static contact baffles in switch cabinet is opened that prevents.
Purpose of the present invention can reach by following measure: a kind of locating locking fixture that prevents that upper and lower static contact baffles in switch cabinet from opening, it is characterized in that it has rotation stop bit handle, rotation stop bit handle is connected and composed by insulated handle and handle screw, handle screw flexibly connects backstay, backstay is provided with positioning pipe, be inserted with two relative cutting ferrules in the positioning pipe and adjust screw rod, one of them cutting ferrule is adjusted on the screw rod and is with spring, another cutting ferrule is adjusted screw rod and is provided with fixing pin, each cutting ferrule is adjusted screw rod and is all connected an adjusting cutting ferrule, and the front end of backstay flexibly connects adjusting screw(rod).
In order further to realize purpose of the present invention, described a kind of locating locking fixture that prevents that upper and lower static contact baffles in switch cabinet from opening, the front end that it is characterized in that described backstay is provided with hold-down nut and is inserted with adjusting screw(rod), and hold-down nut is threaded with adjusting screw(rod)
In order further to realize purpose of the present invention, the front end of described adjusting screw(rod) is provided with the stop bit rubber cushion.
The present invention can produce following good effect compared with the prior art: the present invention will open 2 rollers of upper and lower static contact baffles and fix, thereby prevent the operation of push-pull mechanism, prevented that effectively upper and lower static contact baffles is opened in the intermediate switchgear cabinet cabinet, fundamentally avoided the generation of maintainer's electric shock accidents when maintenance, safe and reliable; The present invention utilizes header board and adjusting screw(rod) and stop bit rubber cushion in the cabinet, can make it secure fixation, installs firmly, and can not damage be arranged to switch cubicle; Charged upper and lower static contact guarantees reliable safe distance when the present invention is provided with insulated handle and can guarantees that operating personnel install and in the cabinet, and then guarantees personal safety; And the present invention has adjustability, utilizes and install built-in spring, alignment pin additional in cutting ferrule, cooperates with rotary handle, can reach the purpose of adjusting roller gap, to satisfy the needs of dissimilar intermediate switchgear cabinets;
