Description
Technical Field
[0001] The utility model belongs to the technical field of geomembrane laying, in particular to a geomembrane laying device. Background Art
[0002] Geomembrane is a geotechnical anti-seepage material made of plastic film as the anti-seepage base material and composited with non-woven fabric. It is a waterproof building material that is anti-seepage and moisture-proof. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. It is often used in the construction of warehouses, dams, cofferdams, canals, artificial lakes, reservoirs and other water conservancy projects.
[0003] The patent with publication number CN218454407U discloses a geomembrane laying device. The utility model can facilitate the movement of the device through universal wheels, and can limit the roller through a limiting mechanism. When the geomembrane outside the roller is used up and the roller needs to be replaced, it is only necessary to pull the handle to pull one end of the limiting rod away from the roller, and then place a new roller between the lower plate and the upper plate, and then insert one end of the limiting rod into the two ends of the roller, so that it is convenient for the staff to replace the roller.
[0004] However, the above-mentioned device is not convenient for flattening the geomembrane during use, which may easily cause bubbles in the geomembrane during the laying process, affecting subsequent construction. Moreover, the above-mentioned device only limits the position of the geomembrane roll by a limit rod, and lacks rotation restriction on the geomembrane roll, which makes it easy for the geomembrane roll to be over-unwound, causing geomembrane accumulation. Reverse rewinding is required afterwards, and the operation is cumbersome. Utility Model Content

A pressure roller 15 is provided, and a slide groove 7 is provided on the side wall of the shell 1. A rack 12 is slidably provided on the slide groove 7, and the rack 12 is meshed with the gear 9. A spring 13 is provided between the rack 12 and the bottom wall of the slide groove 7. When unwinding, the sleeve rod 14 is pulled to adjust the position of the pressure roller 15, and the position of the sleeve rod 14 is fixed by the fixing screw 16. Under the push of the spring 13, the rack 12 moves upward, driving the gear 9 to deflect, and the gear 9 drives the connecting shaft 8 to rotate, so that the connecting rod 10 follows the connecting shaft 8 to deflect, driving the pressure roller 15 to contact with the ground, which can flatten the unwound geomembrane and avoid bubbles between the geomembrane and the ground.
[0023] like Figure 2 As shown, the limited unwinding mechanism 5 includes a driving groove 17 and a geomembrane drum 18. The driving groove 17 is arranged on the side wall of the shell 1. A bidirectional screw rod 19 is rotatably arranged in the driving groove 17. One end of the bidirectional screw rod 19 is provided with a motor 29. The motor 29 is fixedly arranged on the shell 1. A movable block 20 is threadedly connected to the bidirectional screw rod 19. The movable block 20 is symmetrically provided with two groups. A support plate 21 is provided on the movable block 20. A limiting assembly 22 is provided on the support plate 21. The geomembrane drum 18 is arranged between the two groups of limiting assemblies 22. The motor 29 is started to drive the bidirectional screw rod 19 to rotate.
