Description

Pendent lamp is changed instrument

One, technical field

The utility model belongs to a kind of special-purpose maintenance tool of pendent lamp.

Two, background technology

General industry is used very general in workshop with pendent lamp, employed bulb all can damage after arriving useful life, need change.Pendent lamp mostly designs aloft.The common method that more changes the bulb at present is: the staff uses the fork ladder, climbs to the position near pendent lamp, backs out the bulb of damage with hand, replaces with new bulb again.Mainly there is following problem in this method: 1, owing near the position that is not fit to hanging safety belt the pendent lamp, and the danger that exists personnel to fall in the course of work, it is dangerous to work.2, the use of fork ladder is influenced by situations such as light fixture surrounding devices, laying for goods, under have when being unsuitable for an equipment of fork ladder and article and just can't finish maintenance work.3, near high voltage electric equipment, carry out the danger that exists personnel to get an electric shock when pendent lamp more changes jobs.4, the heavy inconvenience that moves of fork ladder causes operating efficiency low.

Three, summary of the invention

The utility model solves the above-mentioned problems in the prior art exactly, provides a kind of pendent lamp safe in utilization, easy and simple to handle, easy to carry to change instrument.

For addressing the above problem, technical solution of the present utility model is: a kind of pendent lamp is changed instrument, and it comprises lamp socket fixture and replacing bulb device; The lamp socket fixture comprises the lock head, handle, backguy and support bar, the lock head is fixed on the support bar, it comprises two lock supports, two lock supports intersect, its crosspoint is fixed on the support bar of lock head by same axle, and it is strutted by stage clip, the inwall of two lock support heads is the plane, backguy one end is fixed therein a lock back-end support, another lock back-end support is passed through in the back of this end, and the other end of backguy is fixed on the handle, and handle rotatably is fixed in the clip by bearing pin, clip is by being bolted on the support bar, and backguy and support bar are insulating material; The replacing bulb device comprises anchor clamps, fixture mount, is fixed together or all-in-one-piece support bar and handle with fixture mount; Anchor clamps have a plurality of pawls, one of them, a plurality of or all be movable claw, its lower end rotatably is fixed on the support by bearing pin, and inwardly strain by extension spring, the outside connects an end of backguy, and the other end of backguy is connected on the handle, handle rotatably is fixed in the clip by bearing pin, clip can not be fixed on the fixture mount by movable claw by being bolted on the support bar, and backguy and support bar are insulating material.

Be fixed with the rubber brake rubber block on the inwall of the head of the lock support of lamp socket fixture of the present utility model.

Intrinsic backguy crust is overlapped on the backguy top of lamp socket fixture of the present utility model.

Overlap rubber sleeve on the pawl of the anchor clamps of replacing bulb device of the present utility model.

Backguy of the present utility model is a nylon material.

Because the utility model has adopted such scheme, the lamp socket fixture is used to catch lamp socket that it is fixed; The replacing bulb device is used to clamp bulb and is rotated, and takes off the old bulb of damage and new bulb is installed.The position of two tool in contact lamp sockets and bulb is elastomeric material, has effectively increased the frictional force of contact site, guarantees can not skid when rotated.The backguy that two instruments are used to the power of transmitting all is insulating material, especially nylon material, can satisfy the insulating requirements of the following electric pressure of 10KV.During use at first a human lamp socket fixture be stuck on the lamp socket, clutch handle, lamp socket is fixed.Another people clutches the handle of replacing bulb device earlier then, and the anchor clamps of upper end are opened, and clamps the bulb of damage, it is bright to unclamp hand then, clamp bulb by the pulling force of spring, the rotation support bar is pulled down old bulb, then with new Clamp for take-down halogen lamp bulb in the anchor clamps of replacing bulb device upper end, new bulb is screwed on the socket, clutch handle once more, anchor clamps are opened, the replacing bulb device is taken off from new bulb, the person's release handle of using the lamp fixing device is then removed this device from light fixture.When using the utility model, the staff may stand in and changes bulb work on the ground, has eliminated the danger that the terraced staff of going up falls accidentally and personnel get an electric shock, more convenient operation, use safer.The use that has also solved the fork ladder is subjected to problems such as surrounding devices restriction, and is lower to the surrounding environment requirement during use, as long as have the people's that can stand position just can use near the light fixture below.Support bar of the present utility model and backguy simultaneously is insulating material, can prevent that effectively the maintenance personal is by electric injury when mistake is bumped charging equipment even if use around charged high-tension apparatus also.It is in light weight, carries, conveniently moving high efficiency.It is applicable to the screw socket light fixture of not being with the sealing lampshade.
