Description
Technical field
The utility model belongs to and unloads the bar technical field of tools, is specifically related to a kind of impacting type rod disassembling device.
Background technology
Rod disassembling device, on some documents, also referred to as nail extractor, the nail extractor of prior art is to adopt the pry type structure mostly, namely establishes prong at the front end of ripping bar, lives nail with the prong fork, the recycling lever principle levers up nail.
China Patent No. ZL201020623998.8 for example, name is called the utility model patent of " a kind of nail extractor ", a kind of nail extractor is disclosed, comprise base, pole, depression bar and handle, described base upper surface middle part is fixedly connected with pole, and described pole top has groove, hinged depression bar in groove, described depression bar one end is fixedly connected with a rectangle plate body, other end connecting handle.This utility model utilizes the v-shaped openings of rectangle plate body front end to live nail with fork, then utilize lever principle that nail is levered up, this nail pulling scheme can't be used for cylindrical bar one class part, and such head can rely on because the cylinder component of rod category is not similar to nail; Secondly, the nail for long because ripping bar can not extend, makes nail pull out half length and just can't continue to pull up later.
China Patent No. ZL200710011930.7 and for example, name is called the patent of invention of " dynamic nail extractors ", discloses a kind of dynamic nail extractors, dop with bayonet is arranged, dop upper end and screw rod active connection of lower end, screw rod upper end are with power sub, and screw rod overlaps movingly threaded sleeve; The bayonet socket of dop is stuck in below the head of a nail, and the power sub of screw rod upper end is connected with the power engine of rotation, and the rotation of engine drives bolt rotary, and screw rod rotates shipper pole relative to screw shell and moves on dop and nail and move, and vertically successfully extracts nail; The threaded sleeve lower surface is patterned surface or toothed surface or corrugated surface, increases the frictional force of screw shell and the material such as wooden around nail, the reliability of increase nail pulling.This invention utilizes the bayonet socket of dop to be stuck in below the head of a nail, then dop is up promoted by the screw thread transmission with power set, and problem is that its bayonet socket is horizontal inverted trapezoidal groove; The deficiency of the outer standby power source of this invention Existence dependency can not be used as passive delivery; Secondly, the same with aforementioned " a kind of nail extractor " patent, there is following defective in this invention: for the cylinder rod workpieces as pin one class, because its bayonet socket is fixed structure, the cylinder rod workpieces but is not similar to the such head of nail can be for promoting, so this nail extractor can't use
China Patent No. ZL200710012992.X for another example, name is called the patent of invention of " hydraulic power nail extractor ", the principle of its nail pulling is basic identical with " dynamic nail extractors ", just power specifically is made as hydraulic coupling, and the clamping ailhead is the inverted trapezoidal groove equally, therefore also has the same defective that can not pull out the cylinder component of rod category.
Summary of the invention
The utility model technical issues that need to address are, the nail extractor existence that overcomes prior art can not rise and pull out cylinder component of rod category or the outer standby power source of dependence, maybe can not work the defective of pulling out the son of having strong market potential, provide a kind of and can work the rod disassembling device that pulls out straight pin class part, this rod disassembling device need not outer standby power source, can work fast the pin rod that pulls out random length, simple in structure, clamping is reliable, easy to operate.
The purpose of this utility model is achieved by following technical proposals: the quick rod disassembling device of a kind of impacting type, comprise hollow pipe, the bottom of hollow pipe is provided with several lock screw, the upper end of hollow pipe is fixedly connected with hammering retaining board, the slide outside cover of hollow pipe has a weight pipe, and the upper surface of weight pipe is corresponding with the lower surface of hammering retaining board.
The bottom of hollow pipe is enclosed within on bar to be pulled pin, follow the precession lock screw, make the afterbody of lock screw withstand on the side of pin rod and further screw, then holding the weight pipe moves upward fast along hollow pipe, utilize the upper end of weight pipe to clash into hammering retaining board, cause that hollow pipe moves up, reach by hollow pipe and drive the effect that is also moved up together by the pin rod of hollow pipe clamping.Working time of collision during due to shock is extremely short, under certain Impulse, impulsive force is very large, this impulsive force is passed to the fixed position of pin rod, can make pin rod loosening fast, then be continued to clash into and extract, this rod disassembling device all is suitable for for the various cylinder pin rods of random length, not only have power and unload greatly and fast the characteristics of bar, the pry type nail extractor that can also avoid prior art is pressed and is made the impaired defective of pedestal or plank surface due to the top of ripping bar fulcrum location.
As preferably, is furnished with lock nut on lock screw.
As preferably, the inner side mounting thread of hollow pipe bottom.Nail or pin rod are pushed up by lock screw be pressed on screw thread, more be conducive to block nail or pin rod.
As preferably, described screw thread is saw-tooth thread.
As preferably, it is spacing that the lateral surface of hollow pipe lower end is provided with the weight pipe.The weight pipe is spacing can prevent that the weight pipe is because deadweight falls to encountering lock screw.
As preferably, the hammering retaining board middle part is provided with through hole.Pull out especially long pin rod for unloading, for easy to operate, after pin rod is extracted certain-length, unclamp lock nut and lock screw, rod disassembling device toward moving down, then is withstood on pin rod lower side position with lock screw, then continue to unload the bar of pulling pin.
The beneficial effects of the utility model are:
1, utilize the weight pipe up to impact to unload bar, power is large, can unload fast bar;
2, can dismantle for all kinds of cylinder pin rods;
3, can dismantle for the pin rod of random length;
