Abstract
The utility model discloses a kind of dedicated hydraulic device for demolition, installation large size bearing, including support ring, the side wall of the support ring is provided with hydraulic strut, one end of the hydraulic strut is provided with top plate, the side wall of the fixed two pieces oil cylinder in the inner of the hydraulic strut, the inside of the oil cylinder are provided with piston, and the upper end of the piston is provided with pull bar, the upper end of the pull bar is provided with link, is connected between the hydraulic strut and oil cylinder by oil pipe.This is used for the dedicated hydraulic device of demolition, installation large size bearing, rational in infrastructure, practical, by the way that bolt is replaced with into hydraulic strut, crane lifts pull bar, and in-oil cylinder hydraulic oil is injected in hydraulic strut, and support ring departs from before ground, the pulling force of pull bar constantly increases, in-oil cylinder hydraulic oil is constantly injected in hydraulic strut, and the support force of hydraulic strut constantly increases, and top plate is tightly blocked bearing inner wall, it is easy to use, and be not in situation about coming off.
Description
Technical field
The utility model belongs to hydraulic means technical field, and in particular to a kind of special liquid for demolition, installation large size bearing
Pressure device.
Background technology
When being dismounted in the prior art to large size bearing, using bolt is turned laterally, make bolt tightly extruding large
The inwall of bearing, this method is very troublesome, and the consuming time is longer, and situation about loosening easily occurs, dangerous bigger,
So need a kind of dedicated hydraulic device for demolition, installation large size bearing.
Utility model content
The purpose of this utility model is to provide a kind of dedicated hydraulic device for demolition, installation large size bearing, with solution
State the problem of being proposed in background technology.
To achieve the above object, the utility model provides following technical scheme：It is a kind of to be used for the special of demolition, installation large size bearing
Hydraulic means, including support ring, the side wall of the support ring are provided with hydraulic strut, and one end of the hydraulic strut is provided with top
Plate, the side wall of the fixed two pieces oil cylinder in the inner of the hydraulic strut, the inside of the oil cylinder is provided with piston, the upper end of the piston
Provided with pull bar, the upper end of the pull bar is provided with link, is connected between the hydraulic strut and oil cylinder by oil pipe.
Preferably, the outer wall of the top plate is provided with skid resistant course.
Preferably, the quantity of the hydraulic strut is no less than three.
Preferably, one end of the hydraulic strut and it is provided with reinforcing plate positioned at the outside of support ring.
Preferably, the thickness of the support ring is not less than five centimetres.
Technique effect of the present utility model and advantage：This is used for the dedicated hydraulic device of demolition, installation large size bearing, and structure is closed
Reason, it is practical, by the way that bolt is replaced with into hydraulic strut, crane lifting pull bar, in-oil cylinder hydraulic oil is injected into hydraulic pressure
In strut, before support ring departs from ground, the pulling force of pull bar constantly increases, and in-oil cylinder hydraulic oil constantly injects hydraulic strut
Interior, the support force of hydraulic strut constantly increases, and top plate is tightly blocked bearing inner wall, easy to use, and is not in come off
Situation.
Brief description of the drawings
