Description
Technical field
The invention belongs to the disassemblerassembler technical field that is used for the threaded engagement parts in the engineer equipment.Be specifically related to the auxiliary equipment device that a kind of hydraulic cylinder sealing cylinder sleeve and hydraulic cylinder screw.
Background technology
In field of engineering technology, exist many parts in many equipment by being threaded, be connected to the connection of hickey between the oil pipeline from little screw, bolt, the hydraulic cylinder of the excavator in the engineering machinery, the tightening and unscrewing of sealing cylinder sleeve between its hydraulic cylinder and the piston rod, have a lot of inconvenience by general spanner, efficient is not high, bad adaptability.When tightening or unscrewing operation, because the restriction of working space must be carried out dismounting repeatedly with spanner, it is time-consuming to require great effort.Though some spanner can be realized just need not dismantling and can reciprocally operate, but present this spanner can only tighten the structure member of the size of a specification, can not regulate the scope of its suitable dimensions, also can only be inserted in simultaneously from the attaching parts two ends, when attaching parts length is very long, just inconvenient, especially when need the clamping part two ends be sealing or exist crooked and when becoming size, this spanner had just lost efficacy.
Summary of the invention
The invention provides a kind of help the enlarging scope of application and adjustable separable reciprocating type spanner easy to use.
The present invention adopts following technical scheme:
A kind of separable reciprocating type spanner, comprise: hold handle, described spanner also comprises annular ratchet, on the end face of annular ratchet, be provided with annular slot rolling, be provided with the arcuation T-slot on the handle holding, described arcuation T-slot embeds the annular slot rolling on the annular ratchet end face and makes annular ratchet rotation relatively take place at the arcuation T-slot, be rotatably connected to the ratchet that matches with annular ratchet on the handle holding, ratchet with hold handle and be provided with holddown spring, on the inner ring surface of annular ratchet, be connected with fixture block, described annular ratchet comprises runner and last runner down, end at last runner is provided with contiguous block, end at following runner is provided with link slot, described contiguous block is suitable with described link slot and be connected by the screw thread bearing pin, the other end at last runner is provided with locked groove, in locked groove, be provided with the retaining projection, the other end at following runner is provided with the snap close that matches with locked groove, described snap close comprises wedge shape dead bolt and lock tongue cavity, described wedge shape dead bolt is connected with lock tongue cavity by the screw that is connected on the lock tongue cavity, be arranged with on the screw between stage clip and stage clip the bottom and wedge shape dead bolt at lock tongue cavity, when snap close buckles into locked groove, the wedge shape dead bolt protrudes in lock tongue cavity and inconsistent with described retaining projection under the effect of stage clip, be provided with unlock hole on locked groove.
Compared with prior art, the present invention has following advantage:
The present invention has realized reciprocating type the rotatablely moving of device, has avoided dismounting clamp operation process repeatedly, has improved the efficient of tightening and unscrew operation of double thread component greatly, more can well adapt to the narrow and small operating environment in space.Because this device is designed to detachable structure, be two semicircular runners and can lead to the locking mechanism folding, can realize separating and closure of two runners, can be installed on easily on the outer ring that will tighten or unscrew parts or on the outerplanar, be easy to install and remove apace, especially also relatively more effective for enclosed construction and endless structure, solved the problem that common wrench can only be inserted in from the structure two ends.Because the clamp module of this device has two parts to constitute, moreover can regulate the scope that clamps size by gears engaged, not only can be suitable for clamping area is the plane situation, also can realize being with the cylindrical chucking of small gap, and suitable size and range of structures are extensive.
Therefore, this device has efficient height, advantage such as applied widely, easy to operate with respect to present spanner.
