Description

Hydraulic puller

Technical field

The utility model belongs to detaching equipment technical field, in particular to hydraulic puller.

Background technique

Hydraulic screw extractor is movement of directly being advanced with oil pressure starting handle, therefore catch bar itself does not rotate, as long as handle when operation It being swung by a small margin before and after hand, the Forward of oil pressure starting handle, the corresponding retrogressing of hook, institute's pulled object pulls out, and it is easy to operate, use province Power is not limited generally by place, be mainly used for the disassembly of the installing component of tight fit, such as the bearing being sleeved on axis is torn open It unloads, the impeller etc. being mounted on an axle.

In the prior art, patent name is disclosed as " Separable self-resetting hydraulic drawing jig ", and openly (bulletin) day is 19880713, the Chinese utility model patent that open (bulletin) number is 87213604 U of CN, which includes working cylinder and drawing Pawl, the top of working cylinder are equipped with plate valve, and pulling claw includes three crotch and drag hook, and three crotch are connected on the pedestal of working cylinder, plate valve There are high-pressure oil pipe joint and low pressure pipe connector above, be connected with handle on plate valve, high pressure in plate valve is controlled by rotating handle The circulating direction of oil, so that working cylinder be driven to run, piston is pushed, positive and negative work of the component for needing to dismantle in conical head and drag hook Under firmly, it is drawn out；Disadvantage is that: the pedestal of working cylinder and three crotch grasped are wholely set, and three crotch are in height Position on direction is fixed, and therefore, when that need to dismantle that distance is little between workpiece and three crotch, hook, which can block, need to dismantle work Part is dismantled, but when distance is larger between workpiece and three crotch, can not adjust the position of pulling claw in the height direction, nothing Method blocks workpiece and completes disassembly, this device disassembly range is small, and practicability is not high.

Utility model content

For the defects in the prior art, utility model aims to solve shortcoming in the prior art, solutions It has determined and has dismantled the small technical problem of range in the prior art, hydraulic puller is provided, this device disassembly range is wide, practical.

Purpose of the utility model is realized as follows: hydraulic puller, including hydraulic cylinder and plate valve, the plate valve peace Mounted in the upper end of hydraulic cylinder, it is connected with handle on plate valve, high-pressure oil pipe and low pressure pipe, institute are connected on the outside of the plate valve It states hydraulic cylinder and is equipped with and the mobile push-pull rod of reciprocating linear, the hydraulic cylinder outside screw can be connected in the height direction Support sleeve moving up and down, the support sleeve lower end are connected with fixed ring, are placed at least two cards on the outside of the fixed ring Pawl.

When the utility model carries out disassembly workpiece, when claw is enough to get at workpiece, claw is first blocked to the work that need to be dismantled Part；When workpiece apart from claw farther out when, can be rotated support sleeve keeps support sleeve mobile toward workpiece direction, when claw blocks workpiece When, stop operating support sleeve, rotating handle, closes the access of low pressure pipe, and the high pressure oil in high-pressure oil pipe enters plate valve, then Through in plate valve input hydraulic pressure oil cylinder, the pressure of high pressure oil is acted on push-pull rod, push-pull rod is contradicted in workpiece axial end and downward Mobile, claw blocks workpiece and moves up, and under the action of both forward and reverse directions active force, workpiece is removed；The utility model The position of middle claw in the height direction is adjustable, realizes large-scale workpiece disassembly, practical；It can be applied to the machine of tight fit In the dismantlement work of tool installing component.

In order to further facilitate disassembly workpiece, the push-pull rod lower end is hinged with protection block.

In order to realize the installation of claw, the top of the claw and fixed ring are connected.

In order to dismantle various sizes of workpiece, the adjustable angle of the claw.

In order to realize the adjustable angle of claw, at least two bindiny mechanisms, the connection are placed on the outside of the fixed ring Mechanism includes screw rod and two engaging lugs, and the claw is rotatably connected between two engaging lugs, and screw rod passes through a connection Ear is connect with claw.

In order to facilitate rotation support sleeve, the fixed ring periphery is equipped at least one convex block.

Wherein, 1 hydraulic cylinder, 2 plate valves, 3 handles, 4 high-pressure oil pipes, 5 low pressure pipes, 6 push-pull rods, 7 support sleeves, 8 is fixed Ring, 9 claws, 10 protection blocks, 11 bindiny mechanisms, 1101 screw rods, 1102 engaging lugs, 12 convex blocks, 13 fixing bolts.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings.

Embodiment 1

Hydraulic puller as shown in figures 1-4, including hydraulic cylinder 1 and plate valve 2, plate valve 2 are mounted on hydraulic cylinder 1 Upper end is connected with handle 3 on plate valve 2, and the outside of plate valve 2 is connected with high-pressure oil pipe 4 and low pressure pipe 5, and hydraulic cylinder 1 is equipped with Can the mobile push-pull rod 6 of reciprocating linear in the height direction, 6 lower end of push-pull rod is hinged with protection block 10,1 outside spiral shell of hydraulic cylinder Line is connected with support sleeve 7 moving up and down, and 7 lower end of support sleeve is connected with fixed ring 8, and 8 periphery of fixed ring is equipped at least one Convex block 12, is placed at least two claws 9 on the outside of fixed ring 8, and in the present embodiment, three claws 9 are placed on the outside of fixed ring 8, The top of claw 9 and fixed ring 8 are connected.

In the utility model, when claw 9 is enough to get at workpiece, claw 9 is first blocked to the workpiece that need to be dismantled；When workpiece away from When from claw 9 farther out, the fixing bolt 13 in 8 outside of fixed ring is unloaded, claw 9 is removed, apply active force to convex block 12, Keep support sleeve 7 mobile toward workpiece direction, when claw 9 can block workpiece, stop operating support sleeve 7, by 9 bottom card of claw Firmly workpiece, while claw 9 being fixed in fixed ring 8 using fixing bolt 13, rotating handle 3, seal the access of low pressure pipe 5 It closes, the high pressure oil in high-pressure oil pipe 4 enters plate valve 2, then through in 2 input hydraulic pressure oil cylinder 1 of plate valve, the pressure of high pressure oil, which acts on, to be pushed away On pull rod 6, push-pull rod 6 is moved down, and protection block 10 is contradicted and in workpiece upper end and moved down, and claw 9 blocks workpiece to moving up Dynamic, under the action of both forward and reverse directions active force, workpiece is removed, and after workpiece disassembles, opposite direction rotating handle 3 is high Access conducting between pressure oil and low pressure oil, high pressure oil oil pressure are removed, and push-pull rod 6 returns to original initial position, that is, can be taken off By drawing workpiece；The utility model, which can be realized, adjusts the position of claw 9 in the height direction, realizes large-scale workpiece disassembly, real It is strong with property, it can be applied in the dismantlement work of the mechanical mounting device of tight fit.

Embodiment 2
