Description

Technical Field

[0001] This utility model relates to the field of tailings dam geomembrane technology, specifically to an installation device for tailings dam geomembrane. Background Technology

[0002] Tailings dams are constructed by blocking valley mouths or enclosing land to store tailings or other industrial waste discharged after ore beneficiation in metal or non-metal mines. Geomembranes are geosynthetic materials made of plastic film as the impermeable base material and non-woven fabric. Their main mechanism is to block water leakage channels with the impermeability of the plastic film, and to withstand water pressure and adapt to deformation with its high tensile strength and elongation.

[0003] In the comparative case, patent publication number CN217974504U discloses an installation device for a tailings dam geomembrane, including a base frame, a support rod fixedly installed on the base frame, casters fixedly installed on the bottom surface of the base frame, a rotating ring movably installed on the support rod, a rotating rod fixedly installed on the rotating ring, and a first-arm tube fixedly installed on the rotating rod. This tailings dam geomembrane installation device belongs to the field of geomembrane laying and installation. Through the structure of the first-arm tube and the second-arm rod, the push tube rotates upward, thereby pushing the geomembrane laterally, causing the geomembrane to roll step by step, thus laying the geomembrane on the bottom surface of the tailings dam. The structure of the first-arm tube and the second-arm rod allows the user to stand and operate the geomembrane rolling, and it is more labor-saving when pushing the geomembrane, thus reducing manpower. This makes the laying and installation of the geomembrane on the bottom of the tailings dam more labor-saving, easier to operate, and reduces fatigue.

[0004] However, during the implementation of the relevant technology, the following problems were found in the installation device of the aforementioned tailings dam geomembrane. The comparative case uses a structure such as a first lever arm pipe and a second lever rod to rotate the push pipe upward, thereby pushing the geomembrane to the side, so that the geomembrane rolls step by step, thus laying the bottom plane of the tailings dam. The structure of the first lever arm pipe and the second lever rod allows the user to stand and operate the geomembrane rolling, and it is more labor-saving to push the geomembrane. In order to prevent polluted water from seeping downward, existing tailings dams need to lay and install geomembranes. The geomembranes on the market are usually large in volume and long in length. When laying, they need to be placed at the top of the slope before rolling them down to the bottom of the slope. The manual operation is slow, time-consuming and labor-intensive, which reduces the working efficiency of the geomembrane installation equipment.

[0005] Therefore, it is necessary to design and modify the installation equipment to effectively prevent the tailings dam from seeping downwards. Tailings dams need to be laid with impermeable membranes to prevent polluted water from seeping downwards. The impermeable membranes on the market are usually large in volume and long in length. When laying them, they need to be placed at the top of the slope and then rolled down to the bottom of the slope in advance. This is a problem of slow efficiency and time and labor consumption for manual operation. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 5 As shown, the present invention provides an installation device for a tailings dam geomembrane, comprising:

[0025] A frame 1 is provided, and a winding machine 2 is fixedly installed inside the cavity of the frame 1. A controller 3 is fixedly connected to the front end of the left side of the frame 1, and a conveying mechanism 4 is fixedly connected to the front and back ends of the right side of the frame 1.

[0026] The conveying mechanism 4 includes a support frame 41, a rotating rod 42, and a reel 43. The support frame 41 is fixedly connected to the front and back ends of the right side of the frame 1. The rotating rod 42 is movably connected to the top of the inner side of the support frame 41 through a rotating shaft. The reel 43 is fixedly sleeved on the surface of the rotating rod 42. The tensioning mechanism 5 is movably connected to the center of the inner cavity of the frame 1 through a rotating shaft.

[0027] refer to Figure 2 The tensioning mechanism 5 includes a cylinder 51, a connecting block 52, a U-shaped frame 53, and an adjusting rod 54. The cylinder 51 is movably connected to the center of the inner cavity of the frame 1 via a rotating shaft. The connecting block 52 is fixedly connected to the front and back ends of the left side of the frame 1. The U-shaped frame 53 is movably connected to the inner side of the connecting block 52 via a bearing. The output end of the cylinder 51 is movably connected to the right side of the U-shaped frame 53. The adjusting rod 54 is fixedly connected to the inner side of the U-shaped frame 53. The traction mechanism 6 is fixedly connected to the left end of the inner side of the frame 1.

[0028] As a technical optimization of this utility model, by setting the tensioning mechanism 5, the cylinder 51 can be activated to drive the U-shaped frame 53 to move. The U-shaped frame 53 rotates around the connecting block 52 to change the angle, and drives the adjusting rod 54 to change the position angle, so that the geomembrane is output through the adjusting rod 54 with different angles and the tension is inconsistent, thus completing the adjustment.

[0029] refer to Figure 4 The traction mechanism 6 includes a cross plate 61, a threaded sleeve 62, a screw 63, a docking plate 64, and a tracked trolley 65. The cross plate 61 is fixedly connected to the left end of the inner side of the frame 1. The front and back ends of the top of the cross plate 61 are movably connected to the threaded sleeve 62 through bearings. The screw 63 is movably connected to the inner cavity of the threaded sleeve 62 through threads. The docking plate 64 is fixedly connected to the left side of the screw 63 through the left side of the threaded sleeve 62. The tracked trolley 65 is fixedly connected to the end of the docking plate 64 away from the screw 63. The flattening mechanism 7 is fixedly connected to the top of the docking plate 64.

[0030] As a technical optimization of this utility model, by setting the traction mechanism 6, the tracked trolley 65 can drive the docking plate 64 and the screw 63 to one side of the threaded sleeve 62. Then the threaded sleeve 62 is fitted onto the surface of the screw 63 and rotated. The threaded sleeve 62 rotates and screws into the surface of the screw 63, so that the threaded sleeve 62 is screwed into the surface of the screw 63 for docking. Finally, the tracked trolley 65 drives the whole to move.

[0031] refer to Figure 5 The flattening mechanism 7 includes a vertical plate 71, a connecting box 72, an electric telescopic rod 73, an H-shaped plate 74, a fixed plate 75, a bracket 76, and a pressure roller 77. The top of the mating plate 64 is fixedly connected to the vertical plate 71. The top of the inner side of the vertical plate 71 is fixedly connected to the connecting box 72. The top of the connecting box 72 is fixedly connected to the electric telescopic rod 73. The bottom of the electric telescopic rod 73 extends through the interior of the connecting box 72 and is fixedly connected to the H-shaped plate 74. The front and back ends of the H-shaped plate 74 are both fixedly connected to the fixed plate 75. The left and right sides of the bottom of the fixed plate 75 are both fixedly connected to the bracket 76. The bottom of the bracket 76 is movably connected to the pressure roller 77. The bottom of the pressure roller 77 extends through the bottom of the connecting box 72.

[0032] As a technical optimization of this utility model, by setting up the flattening mechanism 7, the electric telescopic rod 73 can drive the H-shaped plate 74 to move downward. The downward movement of the H-shaped plate 74 drives the fixed plate 75 and the bracket 76 to move synchronously. The downward movement of the bracket 76 drives the pressure roller 77 to pass through the connecting box 72 and contact the ground, thereby flattening the geomembrane with the pressure roller 77 and avoiding the phenomenon of wrinkles when the geomembrane is directly laid on the ground.

[0033] refer to Figure 5Guide plates 8 are fixedly connected to the left and right sides of the bottom of the inner wall of the connecting box 72. The top of the guide plate 8 passes through the top of the H-shaped plate 74 and is fixedly connected to the top of the inner wall of the connecting box 72.

[0034] As a technical optimization of this utility model, the guide plate 8 can assist the H-shaped plate 74 in its work and also serve as a limit, preventing the H-shaped plate 74 from shifting during its movement.

[0035] refer to Figure 5 An opening 9 is provided at the front and back ends of the bottom of the connecting box 72 and at the position corresponding to the pressure roller 77. The opening 9 is used in conjunction with the pressure roller 77.

[0036] As a technical optimization of this utility model, by setting the opening 9, the pressure roller 77 can be fully transmitted through the opening 9, avoiding the phenomenon that the pressure roller 77 will get stuck at the opening 9 due to the narrow width of the opening 9.

[0037] The working principle and usage process of this utility model are as follows: In use, the geomembrane is first wound around the surface of the winding wheel 43, and one end is passed through the winding machine 2 and fed into the surface of the adjusting rod 54, then hangs down to the ground. At this time, the electric telescopic rod 73 is activated, pushing the H-shaped plate 74 downwards. The H-shaped plate 74 moves vertically along the guide plate 8, simultaneously driving the fixing plate 75. The fixing plate 75 moves downwards, causing the bracket 76 and pressure roller 77 to move synchronously. Then, the pressure roller 77 extends downwards through the opening 9 out of the connecting box 72 to flatten both sides of the top of the geomembrane. Finally, the tracked trolley 65 is activated and moved to the left side of the frame 1. Then, the docking plate 64 and the screw 63 are aligned with the threaded sleeve 62 of the horizontal plate 61, and the process is carried out clockwise. The rotating threaded sleeve 62 is screwed into the surface of the screw 63 for docking. Then, the tracked trolley 65 is started to move the cross plate 61 and the frame 1 as a whole. Finally, the winding machine 2 is started by the controller 3. The winding machine 2 rotates and sends out the geomembrane. The geomembrane traction movement drives the winding wheel 43 to rotate and transport it. The other end is transported to the ground through the adjusting rod 54 and cooperates with the pressure roller 77 to flatten it. If it is necessary to adjust the tension of the geomembrane, the cylinder 51 is started. The cylinder 51 pushes the U-shaped frame 53 to rotate around the connecting block 52. The rotation of the U-shaped frame 53 drives the adjusting rod 54 to change the angle and position. The change in the position and angle of the adjusting rod 54 causes different stresses on the geomembrane, thereby adjusting the tension. The above completes the laying of the geomembrane for the tailings dam.

[0038] In summary, the installation equipment for the geomembrane in this tailings dam works in conjunction with a frame 1, a winding machine 2, a controller 3, a conveying mechanism 4, a support frame 41, a rotating rod 42, a reel 43, and a tensioning mechanism 5. During use, the geomembrane is first wound around the surface of the reel 43, with one end passing through the winding machine 2. When the controller 3 starts the winding machine 2, the geomembrane is conveyed through the winding machine 2 and rotated by the reel 43 and rotating rod 42. The rotating rod 42, along with the support frame 41, supports and fixes the geomembrane to the frame 1, thus achieving the function of conveying the geomembrane. This avoids the phenomenon where the geomembrane cannot be conveyed from the surface of the reel 43. It solves the problem that existing tailings dams require the installation of geomembranes to prevent polluted water from seeping downwards. Commercially available geomembranes are typically large in volume and long in length, requiring pre-positioning them at the top of the slope before rolling them down, resulting in slow, time-consuming, and labor-intensive manual operation.
