Technical Field
[0001] The utility model relates to the technical field related to anti-seepage membranes, in particular to an anti-seepage membrane construction unwinding device. Background Art
[0002] The standard name of the anti-seepage membrane is polyethylene geomembrane, which is mainly made of milky white translucent to opaque thermoplastic resin material - polyethylene resin. Polyethylene is a high molecular polymer, which is non-toxic, tasteless, odorless white particles with a melting point of about 110℃-130℃ and a relative density of 0.918-0.965. The anti-seepage membrane has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness, good mechanical strength, good resistance to environmental stress cracking and tear strength. With the increase of density, the mechanical properties and barrier properties will be improved accordingly, and the heat resistance and tensile strength will be higher. It can resist corrosion such as acid, alkali, and organic solvents; Therefore, the anti-seepage membrane is widely used in environmental protection, sanitation, water conservancy projects, municipal construction projects, garden landscape and greening projects. Among them, a large number of anti-seepage membranes are often needed in municipal construction projects for construction sites. Due to the large-scale use of anti-seepage membranes on large-scale construction sites, a large amount of manpower costs are required. Therefore, it is necessary to place corresponding unwinding devices on the construction site to save manpower time and reduce the physical consumption of personnel during construction.
[0003] In many of the existing unwinding devices for anti-leakage membrane construction, the anti-leakage membrane is placed on a bracket with a roller and unrolled by pulling the anti-leakage membrane. Manual pulling not only consumes a lot of manual physical strength, but also when the anti-leakage membrane on the bracket of the unwinding device is used up, the operator needs to stop the construction work and immediately replace the new anti-leakage membrane before continuing the unwinding operation. In this case, the time for replacing the anti-leakage membrane delays the working time of many construction workers, thereby affecting the construction progress. Therefore, it is necessary to propose an anti-leakage membrane construction unwinding device. Utility Model Content
[0004] The utility model aims to provide an anti-leakage membrane construction unwinding device to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a leakage-proof membrane construction unwinding device comprises a frame, a rotating wheel is installed on one side of the frame, a handle is fixed on one side of the rotating wheel, a fixed ring is fixed on one side of the rotating wheel, a rotating shaft is installed on one side of the fixed ring, a moving ring is movably connected to one side of the rotating shaft, a bolt passes through one side of the moving ring, a fixed sleeve is fixed on one side of the fixed ring, a screw is movably connected to the inner side of the fixed sleeve, one end of the screw is fixedly connected to a pressure block, a ball head is provided on the inner side of the pressure block, a unwinding roller is provided on the inner side of the fixed ring, a reel is provided on the outer side of the unwinding roller, a limiting hole is provided on the inner side of the unwinding roller, a motor is installed above the frame, a linkage block is installed on one output end of the motor, and a connecting rod is fixed on one bottom side of the frame.
[0006] Preferably, the movable ring forms a rotating structure with the fixed ring through a rotating shaft, and both ends of the movable ring are arranged in a "U"-shaped structure.
[0007] Preferably, the movable ring is threadedly connected to the fixed ring via bolts, and the inner diameter of the movable ring is consistent with the inner diameter of the fixed ring.
[0008] Preferably, the pressing block forms a telescopic structure with a fixing sleeve through a screw rod, and the fixing sleeve is distributed in a circumference outside the fixed ring.
[0009] Preferably, one side of the connecting rod is movably connected to a fixing seat, a cylinder is installed above the fixing seat, one side of the cylinder is installed with a piston rod, one side of the piston rod is fixedly connected to a bracket, and the inner side of the bracket is movably connected to a roller.
[0010] Preferably, the bracket forms a telescopic structure with a fixing seat through a cylinder, and the fixing seat is symmetrically arranged with respect to the central axis of the frame.
[0011] Preferably, a limiting plate is fixed on one side of the fixing seat, and a limiting groove is provided on the inner side of the limiting plate.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The unwinding device for anti-seepage film construction uses a rotating wheel, a handle, a fixed ring, a movable ring, bolts and a screw rod in coordination. After the anti-seepage film on the surface of the first roll is used up, the other available rolls placed on the rotating wheel can be replaced by rotating the handle. The screw rods on the fixed ring and the movable ring are first loosened, and then the bolts on the movable ring are loosened to open the movable ring, so that the unwinding roller is fixed to the motor on one side, and then the bolts and screws are tightened to fix the unwinding roller. This avoids the situation where only a single roll can be replaced when there is only one roll on the frame, thereby wasting a lot of time. In this way, after the anti-seepage film is used up, it is only necessary to rotate the rotating wheel, which saves the time of changing the roll, improves the construction efficiency, and speeds up the construction progress.
[0014] 2. The anti-leakage film construction unwinding device is used in coordination with a cylinder, a piston rod, a bracket and a roller. During the use of the device, the piston rod on one side of the cylinder is extended and retracted to drive the connected bracket and the roller to move repeatedly above the anti-leakage film. The roller rolls back and forth above the anti-leakage film to compact the anti-leakage film laid during the construction process, and to drive out excess air between the anti-leakage film and the construction site, thereby avoiding bubbling and affecting the anti-leakage effect of the anti-leakage film.
[0015] 3. This anti-leakage membrane construction unwinding device is used in conjunction with a limiting plate and a limiting groove. During the use of the device, the corners of the anti-leakage membrane are fixed by the limiting groove in the limiting plate. In this way, during the construction of the anti-leakage membrane, the corners of the anti-leakage membrane are fixed by the limiting groove and are not easy to warp. This reduces the chance of the anti-leakage membrane warping during the construction process, allowing the anti-leakage membrane to fully cover the construction site, thereby providing better protection for the construction site.
