Abstract

The utility model discloses a multifunctional dowel dismounting device, which comprises a handle, a pull rod and a plucking head, as well as a sliding handle and at least one connecting rod which are arranged sequentially between the pull rod and the plucking head. A dismounting head can be designed into different types according to different dowel sizes, thereby greatly shortening the time of fast dismounting the dowel in a normal or an undesirable position. The device adopting the integrated structure has the advantages of convenient dismounting, reasonable structure, fast operation, high work efficiency and wide application range.

Description

The multi-functional pin device of tearing open

Technical field:

The utility model relates to a kind of manual teardown instrument, is specifically related to be used to remove the extracting tool of various model pins.

Background technology:

Along with the continuous development of power system, the quantity of transformer station is constantly increasing, and the workload of repairing examination, changing of equipment such as the isolating switch in transformer station, breaker is also more and more.And pins such as split pin, straight pin, bloated pin, taper bolt have obtained a large amount of application as instruments commonly used in power equipment, therefore when equipment such as maintenance isolating switch, breaker, need dismantle this type of a large amount of pins, but owing to be subjected to the influence of factors such as environment, position, a lot of pin corrosions or position are difficult to reach, and just can disassemble thereby cause pin to be difficult to dismounting or need expend great amount of manpower, time.According to statistics, dismantling the not good pin in a corrosion or position sometimes needs 1.5～2 hours, and this has not only reduced operating efficiency, has prolonged the equipment power off time, has influenced economic benefit, has also reduced reliability, the security of power supply simultaneously.Publication number is that the Chinese patent of CN2734428Y discloses a kind of " quick-release pin removal ", constitute by pull bar, block stamp, nut sleeve and screw, by block stamp to the bump of pull bar and the pulling that is screwed into screw in the pin hole, nut sleeve, pin is dismantled, easy to operate, high efficiency, but range of application is very restricted.

The utility model content:

Technical problem to be solved in the utility model provides a kind of multi-functional pin device of tearing open at above deficiency exactly, this tears the pin device open for pin normal or that the position is not good, characteristics according to pin self, Tool for detaching is inserted its afterbody, utilize the inertia that collides generation that pin is extracted rapidly or gone out, high efficiency, dismounting speed is fast, applied range.

Technical solution adopted in the utility model is:

A kind of multi-functional pin device of tearing open includes handle, pull bar and rises and pull out head, and wherein: pull bar also is provided with sliding handle and at least one joint connecting rod successively with pulling out between the head.

Work to pull out between head and the connecting rod being threaded, so that dismounting and replacing.

Rise and to pull out head and comprise that crotch rises and pull out head and straight shape and rise and pull out head, select according to the pin type.

Handle is connected with pull rod screw.

Have connector between pull bar and the connecting rod, be threaded between connector and connecting rod and the pull bar.

Sliding handle is socketed on the pull bar.

Tool for detaching of the present utility model can be according to the different model of design that varies in size of pin, thereby has shortened the not fast quick-detach problem of good pin of normal position or position greatly, and this instrument adopts fabricated structure, easy accessibility, rational in infrastructure, swift to operate, high efficiency, applied range.

Description of drawings:

Fig. 1 rises and pulls out head and be the structural representation of crotch body.

Fig. 2 rises and pulls out head and be the structural representation of straight line body.

The specific embodiment:

The utility model will be further described below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2, this multi-functional pin device of tearing open, include handle 1, pull bar 2 and rise and pull out 6, pull bar 2 pulls out a connecting rod 5 that also is provided with sliding handle 3 successively and is threaded by connector 4 between 6 with rising, rise pull out 6 with connecting rod 5 between be threaded, handle 1 is threaded with pull bar 2, rises to pull out 6 and comprise that crotch rises and pull out 61 and rise with shape directly and to pull out 62, rise and to pull out 6 and can process a series of and pull out head according to size, the model difference of pin; During use, at first select for use different rising to pull out 6 according to the type of pin, position, model etc., should select crotch to rise to pull out 61 for use for split pin, crotch risen pull out 61 and insert in the space of split pin afterbodys, sliding handle 3 then firmly slides, make it on pull bar 2, make back and forth movement, when sliding handle 3 moves to handle 1, owing to stopped, the impact force action of sliding handle 3 is on handle 1, and this impulsive force by handle 1, pull bar 2, rise and act in the split pin after pulling out 6, split pin is formed a power of upwards pulling out, thereby dismantles split pin fast.For straight pin, bloated pin, taper bolt etc., select straight shape to rise to pull out 62 for use, straight shape risen pull out 62 afterbodys that withstand pin, firmly to lower slider sliding handle 3, make it on pull bar 2, make back and forth movement then, when sliding handle 3 moves to connector 4, owing to stopped, the impact force action of sliding handle 3 on connector 4, and this impulsive force by connector 4, connecting rod 5, rise and act on the pin after pulling out 6, pin is formed a power of dashing downwards, thereby dismantle pin fast.
