Description
Technical field
The present invention relates to a kind of nail extractor, be specifically related to the special-purpose rotating nail extractor of a kind of railway signal.
Background technology
In railway signals equipment, the rail of some information need to being usingd transmits as carrier, and rail is not continuous conductor, between every section of rail or rail and trackside equipment room use the various wires that continue (calling wire-connecting in the following text) to be connected, the mode that wire-connecting is connected with rail, for to hole on rail, will be squeezed in rail hole after plug pin on wire-connecting line end.And the line service of railway signals equipment often need to be changed wire-connecting, or the plug pin of wire-connecting need to be pulled up from rail when changing rail.
For a long time, signalman uses is that the mode that the reverse side squeezed into by plug pin by iron punching pin and hand hammer is rushed out plug pin takes down wire-connecting, and the shortcoming of this mode is:
While 1, operating, need a grip rail punching pin handle, another hand is swung hand hammer, and this needs certain skill just can pound accurately, and needs suitable strength;
2, swing and start to hammer into shape the certain space of needs, there being the place of track switch just there is no enough spaces, plug pin can only be chopped off in this case, then from front, use iron punching pin to sweep away plug pin, plug pin has certain tapering, and front goes to use the mode of punching to need larger strength than the first situation;
3, have some specific places, as railway frog core etc., plug pin is squeezed into downwards, and plug pin hole can not be through hole, just use iron punching pin cannot take out plug pin;
4, along with the renewal of railway equipment, some novel bond pin tops, with retaining thread, obviously will be gone out such plug pin and retaining thread will be destroyed now.
In recent years some units, in order to overcome the drawback of aforesaid way, have developed a kind of hydraulic pressure initial line device, and this initial line device utilizes hydraulic principle, and the shortcoming of this mode is:
1, equipment is heavier, signalman's maintenance work is more comprehensive, when work often to carry conventional tool bag (containing 1.25KG hand hammer, 300mm shfting wrench, 27-30 cover pull, various hand vice, instrument, various screwdriver, various box spanners etc.) and the required equipment of working, and a tool hydraulic pressure initial line device is general, just need a signalman to carry separately, significantly affecting operating efficiency;
2, owing to adopting hydraulic principle, have the process of one section of accumulation of pressure when pulling out 21 for line, the phenomenon that just there will be plug pin to eject when pressure is able to overcome resistance and extracts plug pin, if grasp the bad potential safety hazard that just has;
3, hydraulic pressure initial line body is long-pending larger, particularly long, and its total length is about 500mm left and right, is not suitable with at small space and uses;
4, the hydraulic pressure of hydraulic pressure initial line device need to often safeguarded at ordinary times, and its maintenance work is more difficult for signalman, and hydraulic package need be changed by professional, and seal fitting and hydraulic oil Ye Yaoxiang producer buy.
Summary of the invention
