This inner wall shaper for steel tube, including the pneumatic cylinder, a rectangular frame is fixed to the pneumatic cylinder front end, the pneumatic cylinder piston is connected with a hinge four -bar linkage's lower hinge pin, hinge four -bar linkage's last hinge pin is fixed rectangular frame is last, be connected with the arcwall face with steel pipe inner wall profile phase adaptation about hinge four -bar linkage on the hinge pin respectively. The utility model discloses simple structure, it is with low costs, can improve steel pipe remediation efficiency greatly.
Description
Technical field
The utility model belongs to technique of pipe field, relates to a kind of steel pipe fix tool, particularly a kind of inner wall shaper for steel tube.
Background technology
Due to a variety of causes, steel pipe may deform or cave in, the particularly local dent of steel pipe, be difficult to recover, thus cause the steel pipe without much damages not use, particularly require higher pipeline for the round and smooth degree of steel pipe inner wall, the steel pipe more renewed of just having to, adds the cost of equipment.
Find through retrieval, patent " a kind of inner wall shaper for steel tube " (Authorization Notice No. CN202045207U) discloses a kind of machine can repairing steel pipe inner wall, the scheme of this patent only has an arcwall face, but mostly the distortion that steel pipe occurs usually is symmetrical, and arcwall face makes the discontinuity of steel pipe inner wall, inconvenient operation.
Utility model content
The purpose of this utility model there are the problems referred to above for existing technology, and propose a kind of inner wall shaper for steel tube, this device has easy to operate, uniform force application, is beneficial to the feature of repairing the defect claimed steel pipe.
The purpose of this utility model realizes by following technical proposal: a kind of inner wall shaper for steel tube, comprises hydraulic cylinder, and described hydraulic cylinder front end is fixed on a rectangular frame.Described hydraulic cylinder piston is connected with the lower hinge axis of a four-bar linkage.The upper hinge axle of described four-bar linkage is fixed on described rectangular frame, and the left and right hinge axis of described four-bar linkage is connected to the arcwall face suitable with steel pipe inner wall profile.
The operation principle of this inner wall shaper for steel tube is such.Arcwall face is put into distortion place of steel pipe inner wall, hydraulic cylinder piston stretches out, thus four-bar linkage is opened, and arcwall face acts on distortion place of tube wall, the depression of tube wall is propped up.Hydraulic cylinder connected pipes, because oil pipe is flexible, so conveniently can enter in steel pipe with hydraulic cylinder.
In above-mentioned inner wall shaper for steel tube, a stock is fixed in described hydraulic cylinder rear end.Arcwall face can be put into the assigned address of steel pipe by stock, thus realize repairing the defect at steel pipe inner wall diverse location place.
In above-mentioned inner wall shaper for steel tube, the length of described four-bar linkage each bar is identical.
In above-mentioned inner wall shaper for steel tube, described rectangular frame is provided with roller, described hydraulic cylinder rear end is connected with rope.Steel pipe is tilted slightly, utilizes drum can control any deformation place of arcwall face to steel pipe by folding and unfolding rope is convenient in the rolling of steel pipe inner wall.
Compared with prior art, this inner wall shaper for steel tube has the following advantages:
The utility model utilizes four-bar linkage to control two arcwall faces to carry out support to steel pipe inner wall and rise, can make steel pipe uniform force, and be convenient to there being the steel pipe of symmetric deformation to repair simultaneously.The utility model structure is simple, and easy to operate, cost is low, greatly can improve remediation efficiency.
