Description
Technical field
The utility model belongs to insulating tube manufacturing machine field, particularly relates to a kind of outer tube seal gas device.
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.
Utility model content
Main purpose of the present utility model is the deficiency overcoming above-mentioned technology, and provides a kind of outer tube seal gas device.Prevent gas leakage, fixing fastening.
The utility model for achieving the above object, by the following technical solutions: a kind of outer tube seal gas device, 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.The utility model structure 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: the utility model structure 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
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of outer tube seal gas device, comprise movable stand 1, hydraulic cylinder 2, pressing plate 3 and latch 4, described hydraulic cylinder is fixed on the top of described movable stand, and the piston rod of described hydraulic cylinder is connected with described latch, and the both sides of described latch are with U-lag 5, bottom and the described pressing plate of described latch are affixed, described pressing plate bottom is provided with the workbench 6 be mated, and described workbench is fixed on the outside of described movable stand, and the bottom of described movable stand is provided with movable pulley 7.The utility model structure 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.
The both sides of described movable stand are hinged with portable plate 8, described portable plate are fixed with location-plate 9, 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.The both sides of described hydraulic cylinder are provided with positioning sleeve 10, are sliding combined with slide post 11 in described positioning sleeve, and the end of described slide post is connected with described latch.Improve the stability of pressing plate.
The utility model structure 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.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
