Specific embodiment
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 of the lifting part and the right on the left side.
The length of hoisting chain lifting part determines the total length of jack, and jack passes through a series of transmissions（Jack ontology
Transmission mechanism）Chain hoist wheel 2 is rotated to change the length of hoisting chain lifting part, changes to be risen by jack total length
Lift heavy object.Prior art jack, if hoisting chain lifting partial-length is unsatisfactory for job requirement, must just pass through drawing before lifting
Start chain drive chain hoist wheel rotation change hoisting chain lifting partial-length, this process is cumbersome, time-consuming, efficiency is low.
The utility model jack structure as shown in figures 1 to 6, it is a kind of can quick adjustment length jack, including jack ontology
1, the chain mounted on jack body lower part adjusts lockable mechanism 9, hoisting chain 4, the gin wheel being connected with hoisting chain
3, the crampon mechanism 8 being connected with gin wheel,
Chain adjusts lockable mechanism 9, including outside plate 14, ratchet wheel plate 19, adjusts bangle 22, adjusting bangle wheel 21, drive
20th, hoisting chain regulating wheel 16, axis 18,
The middle part of outside plate 14 is provided with axle sleeve mounting hole, top be provided with for the fixed mounting hole of jack ontology,
19 middle part of ratchet wheel plate is installed with ratchet, is provided with axle sleeve mounting hole in the middle part of ratchet wheel plate, top, which is provided with, to be used for
With the fixed mounting hole of jack ontology, axle sleeve mounting hole runs through the ratchet center of circle,
Bangle wheel 21 is adjusted, the provided circumferentially about of hoisting chain regulating wheel 16 has chain section slot, for using chain-driving
It is moved, and is adjusted 21 middle part of bangle wheel and is equipped with axle sleeve mounting hole,
There are three axle sleeve 15, three axle sleeves 15 are corresponding in turn to mounted on adjusting bangle wheel 21, outside plate 14, spine for installation on axis 18
In the axle sleeve mounting hole of wheel plate 19, axle sleeve 15 and axle sleeve mounting hole clearance fit, axis 18 can adjust bangle wheel 21, outside plate
14th, it is freely rotated on ratchet wheel plate 19, drive 20, hoisting chain regulating wheel 16 are fixedly mounted on axis 18, are turned together with axis 18
Dynamic, drive 20, which is located at, to be adjusted between bangle wheel 21 and ratchet wheel plate 19, and hoisting chain regulating wheel 16 is located at ratchet wheel plate 19 and outside plate
Between 14,
Setting is there are four ratchet pin 24 on drive 20 and 19 corresponding surface of ratchet wheel plate, installation pawl 25 and is turned round in detent pin 24
Power spring 26,25 position of pawl correspond to the periphery of the ratchet on ratchet wheel plate, and ratchet bindiny mechanism, transmission are formed with ratchet
Be provided with four arc-shaped slots on wheel 20, arc-shaped slot position corresponds between pawl 25 and ratchet, the length of arc-shaped slot with
Pawl 25 is consistent,
It adjusts bangle wheel 21 and is passed through on drive corresponding to trundle 23, trundle 23 is provided on the face of drive 20
Arc-shaped slot, the space between ratchet and pawl 25,
It adjusts bangle 22 to be mounted on adjusting bangle wheel 21, hoisting chain 4 is mounted in hoisting chain regulating wheel 16, lifting
4 one end of chain bypasses gin wheel 3, and around the chain hoist wheel 2 on jack ontology 1, hoisting chain two ends are fixed to be connected the other end
It connects to form enclosed construction.
When jack is in light condition, need to receive short hoisting chain lifting part, pulls and adjust bangle 22, make adjusting bangle
Wheel 21 rotates clockwise, and 4 trundles 23 rotate simultaneously, and arc groove right end is crossed on drive when trundle reaches（Such as figure
5）When, start that drive is driven to rotate clockwise, drive drives hoisting-chain regulating wheel to rotate clockwise by axis, receives short lifting
Chain lifts by crane part.
Since ratchet is fixed, drive by detent pin band pawl rotate clockwise, trundle be located at pawl tail portion and
Between ratchet, the normal work of ratchet bindiny mechanism is not influenced.
After stopping drag bangle, drive stops operating, and pawl pawl head falls back to hook tooth bottom under the action of the spring.
During jack hoisting heavy, hoisting-chain regulating wheel is acted on by hoisting-chain, rotates counterclockwise trend, but hoisting-chain tune
Section wheel and drive can only unitary rotation, and drive is connect with pawl plate by detent mechanism at this time, is rotated counterclockwise and is hindered
Only, hoisting-chain regulating wheel remains stationary as, and the utility model jack is same to need technology jack equally to complete lifting operation.
When jack is in light condition, and the hoisting chain that need to lengthen lifts by crane part, pulls and adjust bangle, make adjusting bangle wheel
Rotation counterclockwise, 4 trundles rotate simultaneously, and when trundle is to left movement, pawl pawl head is lifted to be detached with ratchet, transmission
Ratchet Joint failure between wheel and ratchet wheel plate（Such as Fig. 6）, drive can rotate counterclockwise.
When trundle reaches drive arc groove left end, start that drive is driven to rotate counterclockwise, drive passes through
Axis drives hoisting-chain regulating wheel to rotate counterclockwise, the heavy chain item that lengthens lifting part.
After hoisting chain lifting partial-length meets job requirement, reversely draw and adjust bangle, make the trundle inverse time
Needle movement a small distance, trundle leave pawl pawl head, and pawl head falls into hook tooth bottom, drive and spine under the action of the spring
Pawl bindiny mechanism between claw-plate restores, and is ready for lifting.
It is directly lifted by crane as non-reverse drawing adjusts bangle, hoisting-chain regulating wheel rotates counterclockwise under the action of hoisting-chain, drives
Drive and pawl rotate counterclockwise, and trundle is motionless, and pawl pawl head leaves trundle, and pawl head falls into spine under the action of the spring
Bottom of the tooth is taken turns, the pawl bindiny mechanism between drive and pawl plate restores, and prevents the counterclockwise movement of drive, and hoisting-chain is adjusted
Wheel stops operating, and lifting operation starts.
Simultaneously the present embodiment be configured 4 sets ratchet bindiny mechanisms be for raising jack bearing capacity, ratchet when specifically used
Bindiny mechanism's quantity can be increased and decreased according to actual conditions.
When jack carries, axis drives drive counterclockwise movement trend, and adjusting bangle wheel can not turn right, meanwhile, spine
Pawl stress is larger, and radial centripetal power is larger, prevents turning left for trundle, makes adjusting bangle during carrying that can not pull.
The utility model has the advantages that chain, which adjusts lockable mechanism, it is more square to adjust chain apart from operating personnel farther out
Just.
