Abstract
An adjustable taper pin hydraulic puller comprises a manual hydraulic pump, wherein the manual hydraulic pump is connected with the piston rod end of a single acting oil cylinder through a hydraulic hose, a welding support is integrally connected with the front end of the single acting oil cylinder, a middle hole round supporting plate is connected with one end of a supporting rod through hinge pin, the other end of the supporting rod is connected with the welding support through welding, a screw cap is arranged at one end of a double-head screw penetrating a front end hole of a piston rod of the oil cylinder, and threads matched with threaded holes in a taper pin and an adjustable opened taper end cover are arranged at the other end of the double-head screw. By adopting the adjustable taper pin hydraulic puller, the pulling problems of the taper pin and the adjustable opened taper end cover can be solved, convenient and quick dismounting is achieved, and the time and labor are saved.
Description
Technical field
The present invention relates to a kind of hydraulic drawing device, especially a kind of adjustable cone pin hydraulic drawing device that cone pin and adjustable opening conical head are pulled out from oil cylinder mounting ear and bracket.
Background technology
In existing hydraulic machinery equipment, the mounting ear of oil cylinder and the adjustable cone pin of bracket are installed and used mode, particularly in imported hydraulic drilling machine equipment the mounting ear of oil cylinder be connected with bracket the overwhelming majority be all adopt adjustable cone pin be connected and installed mode, simply change very time-consuming by knocking with Simple mechanical instrument detachable maintaining, also easily damage pivot pin, axle sleeve, adjustable cone pin drawbench is convenient, fast.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of adjustable cone pin hydraulic drawing device, can solve the problem of drawing cone pin and adjustable opening conical head, realizes conveniently fast disassembling, time saving and energy saving.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of adjustable cone pin hydraulic drawing device, comprise hydraulic hand-pump, hydraulic hand-pump is connected with the tailpiece of the piston rod of one-way cylinder by hydraulic hose, the front end of welding support and one-way cylinder connects as one, middle hole circle supporting plate is connected with pole one end by swivel pin, the pole other end and welding support are welded to connect, double threaded screw is provided with nut through one end of the front aperture of one-way cylinder piston rod, the double threaded screw other end is provided with the screw thread matching with the screwed hole on cone pin and adjustable opening conical head.
The aperture of middle hole circle supporting plate is greater than the external diameter of adjustable opening conical head.
Adjustable cone pin hydraulic drawing device provided by the invention, adopt hydraulic hand-pump to connect double threaded screw one end by the tailpiece of the piston rod of one-way cylinder, the double threaded screw other end is provided with the mode of the screw thread matching with the screwed hole on cone pin and adjustable opening conical head, as long as double threaded screw is screwed in screwed hole, operation hydraulic hand-pump can make cone pin and adjustable opening conical head pull out from oil cylinder mounting ear and bracket, can solve the problem of drawing cone pin and adjustable opening conical head, realize conveniently fast disassembling, time saving and energy saving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the cone pin of institute of the present invention drawing and the pivot pin of adjustable opening conical head, grip assembly figure.
The specific embodiment
As depicted in figs. 1 and 2, the present invention includes hydraulic hand-pump 6, hydraulic hand-pump 6 is connected with the tailpiece of the piston rod of one-way cylinder 8 by hydraulic hose 7, welding support 10 is welded as a whole with the front end of one-way cylinder 8, middle hole circle supporting plate 14 is connected with pole 12 one end by swivel pin, pole 12 other ends and welding support 10 are welded to connect, double threaded screw 9 is provided with nut 13 through one end of the front aperture of one-way cylinder piston rod 11, and double threaded screw 9 other ends are provided with the screw thread matching with the screwed hole 1 on cone pin 3 and adjustable opening conical head 2.
The aperture of middle hole circle supporting plate 14 is greater than the external diameter of adjustable opening conical head 2.
Double threaded screw 9 is Ф 16-30 double threaded screw; Screwed hole 1 is Ф 16-30 screwed hole.
Use procedure of the present invention is as follows:
Double threaded screw 9 is screwed into 1 li of screwed hole on cone pin 3 and adjustable opening conical head 2, the action bars of operation hydraulic hand-pump 6 moves the one-way cylinder piston rod 11 of one-way cylinder 8 in oil cylinder, can make cone pin 3 and adjustable opening conical head 2 pull out from oil cylinder mounting ear 4 and bracket 5.
Pole 12 also can adopt three drag hooks the same with Three-claw pull-horse, be connected with welding support 10, be taper by the Front-end Design of one-way cylinder piston rod 11, just can utilize the present invention belt pulley, gear etc. on all kinds of axles in plant equipment to be carried out quickly and easily from axle to drawing.
