Abstract
The invention belongs to the field of heat insulation pipe manufacturing machines, and particularly relates to a hydraulic air sealing machine for an outer sleeve. The hydraulic air sealing machine comprises a moving frame, a hydraulic cylinder, a pressing plate and a locking plate. The hydraulic cylinder is fixed to the upper portion of the moving frame, a piston rod of the hydraulic cylinder is connected with the locking plate, U-shaped grooves are formed in the two sides of the locking plate, the lower portion of the locking plate is fixedly connected with the pressing plate, a working table matched with the pressing plate is arranged on the lower portion of the pressing plate and fixed to the outer side of the moving frame, and moving wheels are arranged at the bottom of the moving frame. The hydraulic air sealing machine is simple in structure; the hydraulic cylinder arranged on the moving frame can drive the pressing plate to move downwards to be matched with the working table; the hydraulic air sealing machine can effectively prevent air leakage in the blocking process.
Description
Technical field
The invention belongs to insulating tube manufacturing machine field, particularly relate to a kind of outer tube hydraulic pressure envelope mechanism of qi.
Background technology
Prefabricated direct-buried heat insulation pipe is mainly used in district heating outer net pipeline, and along with country is to the popularization of central heating, its consumption is increasing, and the scope of application is also more and more wider.Prefabricated direct-buried thermal insulation pipe road has the plurality of advantages such as waterproof, antiseptic property is good, investment reduction, shortening construction period, maintenance cost are low.
The prefabricated direct-buried pipe of current use is made up of steel pipe, support, heat-insulation layer, outer tube, generally selects seamless pipe spiral welded and straight-seam pipes according to design and customer requirement.Polyethylene jacket pipe adopts high-density polyethylene material to make, and has high mechanical strength and excellent decay resistance, can protect tubing in transportation, installation and use process, avoid the destruction of causing because of extraneous factor.Outer tube needs front end to carry out shutoff in forming process, so that internally inflate, in traditional technology, adopts clamping plate to be fixed, and this kind of mode clamps not tight, easily leaks gas.
Summary of the invention
Main purpose of the present invention is the deficiency overcoming above-mentioned technology, and provides a kind of outer tube hydraulic pressure to seal mechanism of qi.Prevent gas leakage, fixing fastening.
The present invention for achieving the above object, by the following technical solutions: a kind of outer tube hydraulic pressure envelope mechanism of qi, it is characterized in that: comprise movable stand, hydraulic cylinder, pressing plate and latch, described hydraulic cylinder is fixed on the top of described movable stand, the piston rod of described hydraulic cylinder is connected with described latch, the both sides of described latch are with U-lag, bottom and the described pressing plate of described latch are affixed, described pressing plate bottom is provided with the workbench be mated, described workbench is fixed on the outside of described movable stand, and the bottom of described movable stand is provided with movable pulley.Structure of the present invention is simple, by movable stand being provided with a hydraulic cylinder, hydraulic cylinder can be with dynamic pressure plate to move down, and can coordinate with workbench, in use, outer tube one end in forming process is taken on the table, hydraulic cylinder band dynamic pressure plate compresses one end of outer tube downwards, and movable stand can move along with outer tube, thus reaches the object of shutoff, cut by outer tube after shutoff completes, this device can effectively prevent gas leak phenomenon in shutoff process.
Preferably, the both sides of described movable stand are hinged with portable plate, and described portable plate is fixed with location-plate, and described location-plate coordinates with described U-lag.In order to avoid hydraulic cylinder works all the time in the process of shutoff, arranging one can the location-plate of positioning and locking plate, and this location-plate can be stuck in U-lag after rotation, and then ensures that pressing plate is in impaction state all the time all the time, hydraulic cylinder now can not carry out work, cost-saving.
Preferably, the both sides of described hydraulic cylinder are provided with positioning sleeve, are sliding combined with slide post in described positioning sleeve, and the end of described slide post is connected with described latch.Improve the stability of pressing plate.
Beneficial effect: structure of the present invention is simple, by movable stand being provided with a hydraulic cylinder, hydraulic cylinder can be with dynamic pressure plate to move down, and can coordinate with workbench, in use, outer tube one end in forming process is taken on the table, hydraulic cylinder band dynamic pressure plate compresses one end of outer tube downwards, and movable stand can move along with outer tube, thus reaches the object of shutoff, cut by outer tube after shutoff completes, this device can effectively prevent gas leak phenomenon in shutoff process.
Accompanying drawing explanation
