Description

Geomembrane unwinding device

Technical Field

The utility model relates to an unwinding equipment field, in particular to geomembrane unwinding device.

Background

The geomembrane is a watertight mould, and is a geotechnical impervious material compounded by a plastic film serving as an impervious base material and non-woven fabrics, and the seepage-proofing performance of the novel material geomembrane mainly depends on the seepage-proofing performance of the plastic film; at present, plastic films for domestic and overseas anti-seepage application mainly comprise polyvinyl chloride (PVC), Polyethylene (PE) and EVA (ethylene/vinyl acetate copolymer), ECB (ethylene vinyl acetate modified asphalt blended geomembrane) is also designed and used in tunnel application, the ECB is a high-molecular chemical flexible material, the specific gravity is small, the extensibility is strong, the deformation adaptability is high, the corrosion resistance, the low temperature resistance and the freezing resistance are good, the ECB is mainly applied to construction sites, and the geomembrane is harder than common films. In the geomembrane work progress, generally place the geomembrane book on the support that has the roller bearing, unreel through dragging the geomembrane, this kind of mode causes the geomembrane to drag the well deformation easily, unreels at long distance especially, because the change of angle and the drawing of distance are big, and fore-and-aft fold appears easily in the geomembrane.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a geomembrane unwinding device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the geomembrane unreeling device comprises a supporting seat, wherein a roller is fixedly arranged at the top of the supporting seat, and stabilizing plates for fixing the roller are arranged on two sides of the roller; the inner part of the roller is provided with a rolling bearing, the inner part of the rolling bearing is provided with a steel pipe, and one end, away from the rolling bearing, of the steel pipe is provided with a roll core for placing a geomembrane.

Preferably, the diameter that rolls up the core both ends and set up is the same with the inside diameter of steel pipe, just it is fixed to peg graft between core and the steel pipe.

Preferably, the lower end of the supporting seat is provided with a wheel, and the outer material of the wheel is a rubber material.

Preferably, the supporting seat and the two sides of the stabilizing plate are provided with fixing rings, and ropes are arranged on the fixing rings.

Has the advantages that: compared with the prior art, the beneficial effects of the utility model are that: the wheels are arranged at the bottom end of the supporting seat, so that time and labor are saved when the rope is pulled, and the operation is simple; the material of wheel outer lane is rubber materials, and the effectual solution is unreeling the in-process, and the wheel plays the guard action to the geomembrane of laying the completion.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Examples

Referring to fig. 1-4, in an embodiment of the present invention, a geomembrane unreeling device includes a supporting base 1, a roller 2 is fixedly disposed on the top of the supporting base 1, and stabilizing plates 3 for fixing the roller 2 are disposed on two sides of the roller 2; the inner part of the roller 2 is provided with a rolling bearing 7, the inner part of the rolling bearing 7 is provided with a steel pipe 8, and one end, away from the rolling bearing 7, of the steel pipe 8 is provided with a roll core 9 for placing a geomembrane 10.

Further, the diameter that rolls up the setting of core 9 both ends is the same with the inside diameter of steel pipe 8, just it is fixed to peg graft between core 9 and the steel pipe 8.

Furthermore, a wheel 4 is arranged at the lower end of the support seat 1, and the outer part of the wheel 4 is made of rubber; through setting up wheel 4 labour saving and time saving, use the effectual damage of wheel 4 to causing of having avoided when unreeling of rubber materials.

Furthermore, fixing rings 5 are arranged on two sides of the supporting seat 1 and the stabilizing plate 3, and a rope 6 is arranged on the fixing rings 5; the wheel 4 below the supporting seat 1 is pulled to move by the rope 6, so that the unreeling speed is increased.

The use process comprises the following steps:

firstly, a winding core 9 is penetrated in a geomembrane roll, then two ends of the winding core 9 are installed on a steel pipe 8, a support frame 1 moves forwards through a wheel 4 by pulling a rope 6, and then the geomembrane 10, the winding core 9 and the steel pipe 8 are unreeled along with the rotation of a rolling bearing shaft 7, so that the geomembrane 10 is stressed uniformly;

in the process, the wheels 4 are arranged at the bottom end of the supporting seat 1, so that time and labor are saved when the rope 6 is pulled, and the operation is simple; the outer ring of the wheel 4 is made of rubber, so that the problem that the wheel 4 plays a role in protecting the laid geomembrane 10 in the unreeling process is effectively solved; the application has the advantages of simple structure, strong practicability and simple operation and is worth popularizing.

The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
