The application discloses a quick assembly disassembly frock for pulley, including pulley shaft and pulley, still include the base, be equipped with a pair of supporting seat on the base, the concave first recess that is equipped with in top of every supporting seat, the both ends of pulley shaft are equipped with the dog of rectangle and the regulating block of rectangle respectively, dog and pulley shaft integrated into one piece, the concave jack that supplies the pulley shaft embedding that is equipped with on the terminal surface of regulating block orientation pulley shaft, the concave second recess that is equipped with cooperation dog and regulating block embedding respectively in the bottom of two first recesses, it has quick change card bamboo shoot to peg graft in the first recess, the concave screw hole that is equipped with of one end of pulley shaft orientation regulating block, be equipped with the second bolt that runs through the regulating block and be connected with the screw hole on the regulating block. This frock passes through the card bamboo shoot and realizes the fast-assembling to the pulley shaft with the cooperation of first recess to locking through the regulating block realizes adjusting the tensioning of pulley, whole easy dismounting and high efficiency, and the change process is simple laborsaving, and save time has effectively avoided present field to disassemble produced equipment damage problem.
Description
Technical Field
The application relates to the field of tools, in particular to a quick assembling and disassembling tool for a pulley.
Background
In the crane industry, pulley blocks are often used, and a movable pulley block and a fixed pulley block are generally connected by a steel wire rope to carry out lifting operation. Along with the continuous increase of the load that rises, the diameter and the dead weight of assembly pulley also constantly increase, and the change operation of assembly pulley also becomes gradually along with the increase degree of difficulty of its dead weight. Generally, the replacement operation of a large-tonnage pulley block needs to firstly cut off a steel wire rope to separate the pulley block from the steel wire rope, then draw out a pulley shaft from a pulley central hole, and finally take out the pulley. Because there is certain fit tolerance between pulley centre bore and the pulley shaft, so the pulley shaft is difficult to separate with the pulley, and is inconvenient more and consume time when the job site is changed, dismantles pulley and pulley shaft simultaneously by force and causes axle and pulley centre bore cooperation department to appear damaging easily, causes equipment loss.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a quick assembly disassembly frock for pulley to overcome not enough among the prior art.
In order to achieve the above object, the utility model provides a following technical scheme:
the embodiment of the application discloses a quick assembly disassembly frock for pulley, including loose pulley shaft and a plurality of pulleys of assembly on the loose pulley shaft, its characterized in that: the quick-change clamping bamboo shoot is inserted into the first groove, the quick-change clamping bamboo shoot is detachably connected with the supporting seat through a first bolt, a threaded hole is concavely formed in one end of the pulley shaft facing the adjusting block, and a second bolt which penetrates through the adjusting block and is in threaded connection with the threaded hole is arranged on the adjusting block.
Preferably, in the quick assembly disassembly tool for the pulley, the first bolt is provided with a pair, and the second bolt is provided with a pair.
Preferably, in the tool for quickly disassembling and assembling the pulley, the section of the quick-change catch is in an inverted 'T' shape.
Preferably, in the above quick assembly disassembly tool for the pulley, the support seat and the base are integrally formed.
Compared with the prior art, the utility model has the advantages of:
this frock passes through the card bamboo shoot and realizes the fast-assembling to the pulley shaft with the cooperation of first recess to locking through the regulating block realizes adjusting the tensioning of pulley, whole easy dismounting and high efficiency, and the change process is simple laborsaving, and save time has effectively avoided present field to disassemble produced equipment damage problem.
