Abstract
The utility model relates to a hydraulic expander, which comprises an outer sleeve. The outer sleeve is matched with an outer wall and a pedestal of a cylinder sleeve by a built-in sliding liner. A plunger piston is arranged in the cylinder sleeve. Both ends of the plunger piston are respectively provided with seal assemblies. The cylinder sleeve is connected with a hydraulic pipeline. The hydraulic pipeline is provided with a check valve. An upper expanding claw is fixed on the outer sleeve. A lower expanding claw is fixed on the pedestal. The hydraulic expander overcomes the lateral deformation of the plunger piston in the stressing process, prolongs the service life of hydraulic sealing components and guarantees the using effect under the combined action of the plunger piston and the outer sleeve. The hydraulic expander is suitable for accidents such as the colliding, squeezing and deformation of the objects. When the environment has the flammable and explosive possibilities, under the condition that a cutting method is not convenient to be adopted, or when the field is narrow, the working object is not easy to close to and the common tool cannot rapidly play a role, the tool of the utility model can conveniently play a role.
Description
Technical field
The utility model relates to a kind of hydraulic dilatation instrument.
Background technology
The common instrument of recovering uses in object collision, the relief of crimp accident, the occasion of helping out of distress.When environment has inflammable, explosive possibility, inconvenience is taked under the situation of the means of cutting; Perhaps the place is narrow, and when target was not accessible, the common instrument of recovering just can not play a role quickly.
Summary of the invention
The purpose of this utility model is to provide a kind of environment that is applicable to have inflammable, explosive possibility, and inconvenience is taked under the situation of the means of cutting; Perhaps the place is narrow, the hydraulic spreader that uses when target is not accessible.
The purpose of this utility model is achieved in that a kind of hydraulic spreader, comprise outer sleeve, outer sleeve matches with the outer wall and the base of cylinder sleeve by the sliding mats of built-in, plunger places in the cylinder sleeve, the plunger two ends are respectively equipped with black box, and cylinder sleeve is connected with conduit under fluid pressure, and conduit under fluid pressure is provided with check (non-return) valve, last expansion pawl is fixed on the outer sleeve, and following expansion pawl is fixed on the base.
The hydraulic spreader that the utility model provides under the acting in conjunction of plunger and outer sleeve, overcomes the lateral deformation of plunger in loading process, prolongs the service life of hydraulic seal, ensures result of use.Adapt to that object collides, the accident of crimp, when environment has inflammable, explosive possibility, inconvenience is taked under the situation of the means of cutting, perhaps the place is narrow, target is not accessible, and when general tool can not play a role quickly, this instrument can play a role easily.
This hydraulic spreader also can be used as jack and is applied in other working sites.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises outer sleeve 4, outer sleeve 4 matches with the outer wall and the base 11 of cylinder sleeve 3 by the sliding mats 8 of built-in, plunger 2 places in the cylinder sleeve 3, and plunger 2 two ends are respectively equipped with black box 1,5, cylinder sleeve 3 is connected with conduit under fluid pressure 10, conduit under fluid pressure 10 is provided with check (non-return) valve 9, on expand pawl 6 and be fixed on the outer sleeve 4, following expansion pawl 7 is fixed on the base 11.
The course of work of the present utility model is as follows: expander outer sleeve 4 combines with cylinder sleeve 3 outer walls and base 11 by the sliding mats 8 of built-in, when plunger 2 moves under the fluid power effect, plunger 2 promotes outer sleeve 4 and moves in the same way, be fixed on going up on the outer sleeve 4 and expand pawl 6 and the following expansion pawl 7 also rightabout motion thereupon that is fixed on the base 11, target promptly produces extensional motion.The eccentric load that last expansion pawl 6 is born is in the course of the work shared under the acting in conjunction of plunger 2 and outer sleeve 4, overcomes the lateral deformation of plunger 2 in loading process.
Black box 1,5 plays the effect of sealed hydraulic oil, the flow direction of check (non-return) valve 9 control hydraulic oil.In the working site high-pressure hose two ends are connected with snap joint and oil feed pump discharge outlet on the expander conduit under fluid pressure 10 respectively,, can need arrange according to operation and carry out work to its hydraulic oil that injects certain pressure with electric oil pump or manpower oil feed pump.
Claims (1)
1. hydraulic spreader, comprise outer sleeve (4), it is characterized in that: outer sleeve (4) matches with the outer wall and the base (11) of cylinder sleeve (3) by the sliding mats (8) of built-in, plunger (2) places in the cylinder sleeve (3), and plunger (2) two ends are respectively equipped with black box (1,5), cylinder sleeve (3) is connected with conduit under fluid pressure (10), conduit under fluid pressure (10) is provided with check (non-return) valve (9), on expand pawl (6) and be fixed on the outer sleeve (4), following expansion pawl (7) is fixed on the base (11).
