Specific implementation mode
Embodiment 1
As shown in Fig. 2, prior art jack hoisting chain 4,5, between bearing pins 6 and unloaded pin 7, chain hoist wheel 2 will
It is divided into the reserve fraction 5 of the lifting part 4 and the right on the left side.
The length of hoisting chain lifting part 4 determines that the total length of jack, jack pass through a series of transmissions（Jack ontology
Transmission mechanism）Chain hoist wheel 2 is rotated to change the length that hoisting chain lifts by crane part 4, is changed by jack total length to carry out
Hoisting heavy.Prior art jack, if hoisting chain lifting partial-length is unsatisfactory for job requirement, must just pass through before lifting
It pulls bangle that chain hoist wheel rotation is driven to change hoisting chain and lifts by crane partial-length, this process is cumbersome, time-consuming, efficiency is low.
As shown in Figs. 1-5, a kind of jack for capableing of quick adjustment length, including jack ontology 1, chain adjust lockable mechanism
9, hoisting chain, the gin wheel 3 being connected with hoisting chain, the crampon mechanism 8 being connected with gin wheel 3,
It includes four-bladed vane 10, slipping ring 11 that chain, which adjusts lockable mechanism 9, and two bar grooves intersected in length and breadth are provided on four-bladed vane 10
Hole, slot width are slightly larger than hoisting chain anchor chain diameter, and transverse groove hole length is slightly larger than the width of hoisting chain chain link, longitudinal slot position
Length in lateral slot top is slightly larger than the half of hoisting chain chain byte wide, and longitudinal slot is located at the length of lateral slot lower part
Degree is more than the width of hoisting chain chain link, and longitudinal slot top is provided with fixed pin holes in fixed plate, is equipped in fixed plate
Backing pin 12, lower backing pin 13, slipping ring 11 are sleeved on four-bladed vane 10, between upper backing pin 12 and lower backing pin 13, lower backing pin 13
When installation site is that slipping ring 11 moves on to following, longitudinal slot is made all to expose, the installation site of upper backing pin 12 is that slipping ring 11 moves on to
When top, 11 shield portions longitudinal slot of slipping ring makes longitudinal slot exposed length be slightly larger than hoisting chain width,
Chain adjusts lockable mechanism 9 and is mounted on 1 time middle side part of jack ontology,
Hoisting chain passes through the slot intersected in length and breadth on four-bladed vane, hoisting chain to adjust locking by chain hoist wheel 2 and chain
Mechanism 9 is divided into hoisting chain（Lift by crane part）4, hoisting chain（Reserve fraction）5, hoisting chain（Lift by crane part）4 bypass
Weight pulley 3, hoisting chain（Reserve fraction）5 are fixedly connected with shape around the chain hoist wheel 2 on jack ontology, hoisting chain two ends
At enclosed construction.When hoisting chain passes through four-bladed vane, when above the cross bore that longitudinal slot, lateral slot are formed（Figure
5）, hoisting chain can be controlled and be moved freely, when hoisting chain is located at below cross bore（Fig. 4）, a chain link enters pod bottom hole
Behind portion, adjacent left and right chain link is horizontal to be stuck in four-bladed vane pod both sides, keeps hoisting chain stuck, can not be moved left and right with respect to four-bladed vane.
The utility model hoisting chain is changed to enclosed construction by the open architecture of the prior art, at the same eliminate bearing pins with
Unloaded pin increases chain and adjusts lockable mechanism 9.
When hoisting heavy, chain adjusts lockable mechanism and locks its relative position with hoisting chain, by pulling bangle band
Dynamic chain hoist wheel rotation, adjusts hoisting chain and lifts by crane partial-length, changes jack total length and completes lifting operation, process completely with
Prior art jack is identical.
Before the lifting of the utility model jack, such as lifts by crane partial-length and be unsatisfactory for job requirement, it is not necessary to pull bangle, keep
Heavy chain wheel is motionless, and adjusting lockable mechanism by chain makes the change of itself and the relative position of hoisting chain be risen to change hoisting chain
The length of hanging part point complies with lifting and requires.
The utility model jack lifts by crane working condition when carrying, and hoisting chain has a section to fall into four-bladed vane cannelure at this time
Hole bottom, hoisting chain adjust lockable mechanism latched position by chain, change hoisting chain lifting by the rotation of chain hoist wheel
Partial length carries out lifting operation.
The chain link on four-bladed vane is stuck under the action of the hoisting chain pulling force of right side, can only be close to pod bottom can not be upward
It is mobile, it is ensured that hoisting chain adjusts lockable mechanism secure ratcs with chain.
The utility model jack zero load adjusts working condition when hoisting chain length, and pushing up slip ring makes hoisting chain
It is left above four-bladed vane（It is right）Hoisting chain is pulled, the length of hoisting chain lifting part is made to meet job requirement.
Embodiment 2
As shown in fig. 6, chain adjusts lockable mechanism, for a straight panel, skewed slot is provided in straight panel, skewed slot is wide to be slightly larger than jack
Hoisting chain anchor chain diameter, groove depth are more than jack hoisting chain outer width.
Before lifting, hoisting chain one is saved into centre as needed and is hooked on hook plate.
