Abstract
Disclosed is an isolation-switch contact-finer dismounting device which includes a base and handles, and the two handles are hinged through a hinging shaft. A round shaft is arranged vertically on the base. The hinging shaft is provided with a moving positioning rod. The front end of the moving positioning rod is provided with a round ring. The round shaft is sleeved with the round ring. The rear part of the moving positioning rod is provided with a slide groove. The hinging shaft is located in the slide groove. The end parts of the handles are provided with contact-finger snap joints. A screw rod is arranged between the two handles. An adjustment handle is arranged on the screw rod. Through adoption of the technical scheme, the contact-finger snap joints are arranged at the end parts of the handles and the screw rod is arranged between the two handles and the adjustment rod is arranged on the screw rod. Thus, when a spring is dismounted, the adjustment handle can be slowly flicked so that the adjustment handle moves on the screw rod and thus the opening degree between the handles is adjusted slowly and it can be ensured that during a spring dismounting process, the spring does not burst open and thus the personal security of work personnel is ensured.
Description
Technical field
The present invention relates to a kind of electric power aid, specifically relate to a kind of device of dismounting isolating switch fingertip.
Background technology
To isolating switch, maintenance is matter of frequent occurrence to power industry, and to isolating switch, maintenance generally all needs dismounting fingertip.At present, be mostly adopt dismounting hand-manipulated, there is many defects in this original manual assembly and disassembly methods: 1., because spring tension very large, generally need personnel's ability dismounting that strength is larger, and disassembly process requires high to operating personnel's practical experience, operation easier is large; 2., manual dismounting is large to the damage of fingertip, spring, easily causes associated components to damage, and not only increased the cost of overhaul, but also needed dismounting again, increased working practice; 3., because operation easier is large, once careless manipulation just likely causes danger, injury operating personnel, affect normal service work.
Summary of the invention
The isolating switch fingertip attaching/detaching apparatus of the object of this invention is to provide a kind of handling safety, increasing work efficiency.
For achieving the above object, the present invention is by the following technical solutions:
A kind of isolating switch fingertip attaching/detaching apparatus, it comprises base and handle, and hinged by jointed shaft between two handles; Circular shaft is vertically set on base, motion positions bar is set on jointed shaft, motion positions bar front end arranges annulus, and annulus is sleeved on circular shaft; Motion positions bar rear portion is provided with a chute, and jointed shaft is positioned at chute inside; Be provided with fingertip buckle in described handle end, and between two handles, screw mandrel be set, regulating handle is set on screw mandrel.
On described jointed shaft, be combined with the nut that prevents that motion positions bar from coming off.
Adopt the present invention of technique scheme, be provided with fingertip buckle in handle end, and between two handles, screw mandrel be set, regulating handle is set on screw mandrel.Like this, in the time of dismounting spring, can slowly pull regulating handle, regulating handle is moved on screw mandrel, thereby the opening degree slowly between regulating handle can guarantee like this tearing open in spring-loaded process, spring can not collapse and hold, and has guaranteed staff's personal safety.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention includes base 1 and handle 8, and hinged by jointed shaft 6 between two handles 8; Circular shaft 3 is vertically set on base 1, the backstay 4 that can move along it is set on jointed shaft 6, backstay 4 front ends arrange annulus 2, and annulus 2 is sleeved on circular shaft 3; Backstay 4 rear portions are provided with a chute 7, and jointed shaft 6 is positioned at chute 7 inside.Meanwhile, on jointed shaft 6, be combined with the nut 9 that can prevent that backstay 4 from coming off.
The present invention is provided with fingertip buckle 5 in handle 8 ends, and screw mandrel 10 is set between two handles 8, regulating handle 11 is set on screw mandrel 10, like this, in the time of dismounting spring, can slowly pull regulating handle 11, regulating handle 11 is moved on screw mandrel 10, thereby the opening degree between regulating handle 8 slowly can guarantee like this tearing open in spring-loaded process, spring can not collapse and hold, and has guaranteed staff's personal safety.
