Description
Technical field
The invention belongs to lifting equipment technical fields, and in particular to a kind of unilateral manual locking system of double-column lifter.
Background technology
Double-column lifter is a kind of motor vehicle repair and the maintenance common special-purpose machinery lifting equipment of unit, is lifting machine
Main Types are widely used in the repair and maintenance of the compact cars such as car.A pair is generally included to face each other in left and right two
The column of side setting, the sliding block being separately positioned in a column and jacking cylinder and the lockable mechanism for locking sliding block,
Wherein lockable mechanism is one of the critical component that sliding block surprisingly glides in order to prevent, is guarantee and the user's choosing of life security
Select one of the important consideration standard of lifting machine.Double-column lifter currently on the market, lockable mechanism are broadly divided into electric locking
With two kinds of manual locking, the cost of wherein electric locking device is higher, generally uses the structure of unilateral unlock, although locking acts
Stablize, is reliable, but there is electric operatings to be easy failure and the high drawback of maintenance cost；And manual locking system, in order to
The reliability and safety that guarantee uses, the structure of the bilateral unlock of generally use, but involved by bilateral manual locking system
Amount of parts is more, cumbersome, and connection installation difficulty is higher, and cost is more than recited above electronic instead sometimes
Locking system.
In prior art, one kind " pedestal as disclosed in Chinese utility model patent Authorization Notice No. CN205687466U
Formula double-column lifter unilateral unlock Double-linkage safety structure manually ", including head tree, secondary column, oil pipe backplate, slide, power
Unit, slide are equipped with slide security bar and are connected with trailing arm；Head tree, secondary column are respectively equipped with main insurance, secondary insurance, main guarantor
Danger, secondary insurance include the first safety hook, the second safety hook and linkage part, the first safety hook of main insurance, pair
First safety hook of insurance moves synchronously；First safety hook of main insurance is connected with safety handle, in the drive of safety handle
Under dynamic, the first safety hook of main insurance drives the cunning of the second safety hook linkage and slide in head tree by linkage part
Terraced security bar forms locking and unlock, the linkage pair that secondary the first safety hook insured, the second safety hook pass through linkage part
The slide security bar of slide forms locking, unlock in secondary column.Deficiency is existing for the technical solution：Use multiple idler wheel phases
Connect the structure for making safety device mutually link, and amount of parts is more, complicated, and installation maintenance difficulty compared with
Greatly.
In view of the foregoing, it is necessary to design a kind of amount of parts it is less, it is simple in structure, be easily installed maintenance, favorably
In cost-effective and the safe and reliable high double-column lifter of property of action unilateral manual locking system.For this purpose, the applicant makees
Beneficial design, technical solution described below generate in this background.
Invention content
It is simple in structure task of the invention lies in a kind of unilateral manual locking system of double-column lifter of offer, zero

The elastic force end of pull-rod spring 523, the pull-rod spring 523 acts against on jam plate 522 and jam plate 522 is made to be resisted against under lock convex 21
Square and realization and slide unit 2 locking, the mandril 511 are then resisted against on the step surface of 522 inclined-plane lower end of jam plate；When described
When mandril 511 moves up and jam plate 522 is pushed to squeeze pull-rod spring 523, the jam plate 522 can be forced to be detached from and lock convex 21 and match
It closes and realizes the unlock with slide unit 2.
Further, the upper end composition of the jacking cylinder 3 has an oil cylinder idler wheel 31, is set on the oil cylinder idler wheel 31
Be equipped with a leaf chain 32, the leaf chain 32 after around oil cylinder idler wheel 31 its both ends respectively be fixed on 2 inside lower end of slide unit
Slide unit leaf chain fixed seat 22 and the oil cylinder leaf chain fixed seat 33 being fixed on 3 pedestal of jacking cylinder connect, the jacking oil
The lower end of cylinder 3, which is constituted, a fuel feed hole 34 and an oil outlet 35, and the fuel feed hole 34 and oil outlet 35 connect with oil pump 4 respectively
It is logical.
Further, it is additionally provided with a safety device 6 on the slide unit 2, which is separately positioned on including one
The insurance idler wheel 61 of 1 inside top of arranged on left and right sides column, a pair of 62 and of insurance guide wheel for being separately positioned on 3 bottom of jacking cylinder
A pair of of safety lanyard 63, the slide unit 2 are respectively arranged with a safety lanyard upper connecting base 23 and one guarantor on the medial surface of upper end
Dangerous steel wire lower connecting base 24, described 63 one end of safety lanyard are fixedly connected with the safety lanyard lower connecting base 24 of a side slid platform 2,
The safety lanyard 63 extends downwardly and the insurance guide wheel 62 around 3 lower section of the same side jacking cylinder, opposite other side jacking cylinder 3
It is connected on the safety lanyard of another side slid platform 2 after the insurance idler wheel 61 at 1 top of insurance guide wheel 62 and another heel post of lower section
Seat 23 is fixedly connected.
Further, 2 both sides of slide unit are respectively arranged with one group with column 1 with merging in 1 short transverse of column
The sliding block 25 of lower slider.A pair of of lifting foot 26 is also rotatably connected on the slide unit 2.
Further, it is provided with a cover board 7 between a column 1, the cover board 7 lid is located between a column 1
54 top of steel wire rope of connection.
Further, the locking bar 51 offers one in the end of upper and lower ends and extends along 1 short transverse of column respectively
Slot hole 515, the locking bar 51 by slot hole 515 by fastener be mounted on column 1 on and can slide up and down.
Fig. 2, Fig. 3 and Fig. 4 are please referred to Fig.1 and combine, when the driving oil pump 4 works, the top of arranged on left and right sides
The jacking upwards simultaneously of oil-lifting jar 3, the oil cylinder idler wheel 31 of 3 upper end of the jacking cylinder pushes leaf chain 32 upwards, since this is board-like
32 one end of chain is fixed on 3 lower end of jacking cylinder, and the other side is fixed on slide unit 2, thus leaf chain 32 drives slide unit 2 to lift upwards
It rises, for the slide unit 2 in uphill process, the lock convex 21 of 2 rear side of slide unit squeezes jam plate 522 respectively, makes the overturning of jam plate 522 simultaneously
Block and be set to the lower section for locking convex 21 accordingly, is acted so as to complete the locking of slide unit 2 and column 1.When slide unit 2 needs unlock,
The handle 57 is pulled downwards, and the handle 57 is described at this time with the operating lever 514 on moveable lock hook 572 upwards lifting locking bar 51
Locking bar 51 along slot hole 515 length direction upward sliding, since the locking bar 51 of arranged on left and right sides passes through right rope sling respectively
55, left rope sling 56 and locking bar guide wheel 53 synchronize connection, thus the locking bar 51 of arranged on left and right sides passes through respective top simultaneously
Bar 511 push up respectively corresponding jam plate 522 squeeze pull-rod spring 523, force jam plate 522 be detached from lock convex 21 cooperation and
The unlock for completing slide unit 2, drives 4 oil return of oil pump, the jacking cylinder 3 of arranged on left and right sides to move down simultaneously at this time
Until slide unit 2 resets.When fracture occurs for the leaf chain 32 of side, and slide unit 2 is made to drop, the insurance that is connected on the slide unit 2
Bearing down is transferred to the other side by steel wire 63 by the insurance guide wheel 62 of 3 lower section of insurance idler wheel 61 and both sides jacking cylinder of top
Slide unit 2 on, fall caused casualties and property loss to effectively prevent slide unit 2.
