Description

Technical Field

[0001] This utility model relates to the field of geomembrane technology, and in particular to a geomembrane covering and cutting device. Background Technology

[0002] Geomembranes are commonly used in water conservancy projects to form protection at the bottom of lakes and dams, effectively preventing soil and water seepage and enhancing soil stability. During the laying process, the edges of adjacent geomembranes need to be welded together to form a whole. Currently, due to the harsh on-site construction environment, the surface of the geomembrane is often dirty and messy, which seriously affects the welding quality of the geomembrane. After welding, there will be leaks, thus failing to meet the quality requirements of the project to prevent leakage. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a geomembrane covering and cutting device, which can cover and protect the geomembrane during the production process to ensure the welding quality of the geomembrane.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A geomembrane covering and cutting device includes a geomembrane and a covering assembly, characterized in that: the covering assembly includes a base plate and a covering component and a cutting tool connected to the base plate;

[0006] The geomembrane is blow-molded, has an annular cross-section, and moves from bottom to top;

[0007] The base plate is fixedly installed, and the cutting tool is located at the geomembrane cutting operation position and cuts the geomembrane along the axis.

[0008] The covering assembly includes two sets, located on the inner and outer sides of the lower part of the geomembrane segmentation operation position, respectively. The covering roller includes a covering roller and a protective film roll. The covering roller is located at the upper part, and the protective film roll is located at the lower part. The covering rollers of the two sets of covering assemblies press the geomembrane at the same position, and the protective film of the protective film roll is attached to the surface of the geomembrane by the pressing action of the covering roller.

[0009] The substrate includes an inverted U-shaped bracket connected thereto, with the middle part of the inverted U-shaped bracket located above the cutting tool, and the two side brackets of the inverted U-shaped bracket located on the inner and outer sides of the geomembrane, respectively. The membrane covering assembly is installed on the inverted U-shaped bracket.

[0010] The inverted U-shaped bracket is equipped with a mounting frame corresponding to the coating assembly, and the coating roller and protective film roll of the coating assembly are rotatably mounted on the mounting frame.

[0011] The outer surface of the substrate is provided with side lugs for connection and fixation.

[0012] The inner surface of the substrate is provided with a tool holder that is fixed to it, and a tool that is detachably connected to it is mounted on the tool holder.

[0013] The cutting tool is tilted as a whole, with its front end lower than the fixed other end.

[0014] In summary, this utility model has the following beneficial effects: the structure is reasonably designed, and the protective film is continuously applied and cut during the geomembrane blow molding process. After the geomembrane is unfolded, the protective film will remain at the welding positions on both sides of the geomembrane. During on-site construction, the protective film can be peeled off before welding to remove it from the geomembrane, thereby ensuring the cleanliness of the surface of the geomembrane welding part and thus ensuring the welding quality between geomembranes.

[0019] according to Figures 1 to 3 As shown: This utility model provides a geomembrane covering and cutting device, including a geomembrane 600 and a covering assembly 100. The geomembrane 600 is blow-molded, its cross-section is annular, and it moves from bottom to top. The covering assembly 100 is installed and fixed on the geomembrane 600 blow molding equipment for fixation.

[0020] The coating assembly 100 includes a substrate 100 and a coating component and a cutting tool 200 connected to the substrate 100, wherein:

[0021] The outer surface of the substrate 100 is provided with a side lug 102 for connection and fixation. The side lug 102 is used for installation and fixation on the geomembrane 600 blow molding equipment, so that the membrane assembly 100 can be fixed in the designated working position.

[0022] The inner surface of the substrate 100 is provided with a knife holder 103 that is connected and fixed thereto. A knife 200 that is detachably connected to the knife holder 103 is installed on the knife holder 103. The knife 200 is inclined as a whole, and its front end is lower than the other fixed end. This can prevent the knife 200 from detaching from the geomembrane 600 and cut the geomembrane 600 along the axis at the cutting operation position, ensuring the cutting operation effect.

[0023] The base plate 100 includes an inverted U-shaped bracket 101 connected thereto. The middle part of the inverted U-shaped bracket 101 is located above the cutter 200. The two side brackets of the inverted U-shaped bracket 101 are located on the inner and outer sides of the geomembrane 600, respectively. The membrane covering assembly is installed on the inverted U-shaped bracket 101, so that the membrane covering assembly can cooperate with the closed structure inside the geomembrane 600 and install part of the membrane covering assembly inside the geomembrane 600 to achieve the effect of simultaneous membrane covering on both the inner and outer sides of the geomembrane 600.

[0024] The covering assembly includes two sets, located on the inner and outer sides of the lower part of the geomembrane 600 at the segmented operation position, respectively. The covering roller 400 includes a covering roller 400 and a protective film roll 300, with the covering roller 400 located at the upper part and the protective film roll 300 located at the lower part. The inverted U-shaped bracket 101 is equipped with a mounting frame 500 corresponding to the covering assembly. The covering roller 400 and the protective film roll 300 of the covering assembly are rotatably mounted on the mounting frame 500, respectively. At the same time, the covering rollers 400 of the two sets of covering assemblies press against the geomembrane 600. At the same position on the geomembrane 600, the protective film of the protective film roll 300 is attached to the surface of the geomembrane 600 by the pressing action of the covering roller 400. The protective film surface has an adhesive layer, which can be attached to the surface of the geomembrane 600. The covering roller 400 can keep it flat by pressing. The power source for the covering process is the traction of the geomembrane 600 by the geomembrane 600 blow molding equipment. The covering assembly 100 itself has no power, so it can be synchronized with the moving speed of the geomembrane 600 to ensure the synchronous effect of covering.

[0025] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
