Description

Technical Field

[0001] This invention relates to the field of construction equipment technology for tailings dam seepage prevention projects, and in particular to a lightweight membrane laying machine suitable for plateau and mountainous terrain. Background Technology

[0002] In the construction and operation of tailings dam projects in high-altitude mountainous areas, dam seepage prevention is a core process for preventing tailings leakage, protecting the surrounding ecological environment, and ensuring the structural safety of the tailings dam. HDPE geomembrane, with its excellent seepage prevention performance, weather resistance, and terrain adaptability, is widely used in seepage prevention systems for various areas of the tailings dam, including the main reservoir area and dam slopes. To ensure structural stability and smooth drainage on the slopes, tailings dam bodies typically have multi-level walkways, steps, and supporting drainage ditches constructed on the slopes. These areas are a crucial component of the dam's seepage prevention system, and their installation quality directly determines the integrity and operational reliability of the entire tailings dam seepage prevention system.

[0003] Currently, large-scale automated geomembrane laying operations in the main tailings dam area mostly utilize large-scale automated geomembrane laying equipment, which boasts high operational efficiency and can meet the continuous laying requirements of large-roll HDPE geomembranes. However, in narrow and confined areas such as multi-level walkways, steps, and drainage ditches within the dam body, large geomembrane laying equipment exhibits significant operational limitations: on the one hand, the equipment's overall size and weight are substantial, making it impossible to enter the work area due to the width limitations of walkways and steps. Even if it manages to enter, it struggles to perform turning and other maneuvers, making it unsuitable for narrow and elongated work spaces; on the other hand, large equipment experiences high ground pressure when operating on steep slopes, easily leading to slippage, tilting, and other safety hazards, thus compromising the stability of steep slope operations.

[0004] While existing small-scale geomembrane laying equipment can operate in some narrow areas, it lacks adaptability to the rugged terrain of tailings ponds in high-altitude mountainous areas: First, the equipment's walking mechanism lacks terrain-following capability, making it prone to jamming and stagnation on uneven and irregular terrain, hindering continuous and stable operation; second, the unwinding mechanism and walking mechanism lack synchronous transmission design, which can easily cause the geomembrane to stretch and break or loosen and wrinkle when the walking speed changes, making it impossible to ensure the flatness of the laying; third, the lack of an effective braking and speed regulation mechanism makes it prone to slippage and loss of control when operating on steep slopes, posing a risk of equipment tipping over and easily damaging the geomembrane due to sudden changes in wheel speed. Therefore, this application proposes a lightweight geomembrane laying machine suitable for high-altitude mountainous terrain. Summary of the Invention

[0005] The purpose of this invention is to address the problems in the prior art, such as the large size and heavy weight of large membrane laying equipment, which makes it impossible to enter narrow areas such as tailings dam access roads, steps, and drainage ditches, and the tendency to slip and tilt when operating on steep slopes, as well as the poor terrain adaptability, asynchronous unwinding, and lack of braking protection of existing small membrane laying equipment, which easily lead to damage to the geomembrane and low operational safety. The invention proposes a lightweight membrane laying machine suitable for plateau and mountainous terrain.

[0008] Optionally, a circular stop is fixed to the surface of the fixing frame, and a second spring is provided between the top of the circular stop and the bottom of the mounting frame.

[0009] Optionally, the limiting component includes an arc-shaped plate, two sets of rectangular blocks, a limiting rod, and a first spring. The two sets of rectangular blocks are fixedly positioned at an interval on the inner side of the connecting block. The limiting rod slides through the rectangular blocks. The bottom of the limiting rod is fixedly connected to the top of the arc-shaped plate. The first spring is sleeved on the surface of the limiting rod. The top of the first spring is fixed to the bottom of the rectangular blocks, and the bottom of the first spring is fixed to the top of the arc-shaped plate.

[0010] Optionally, the limiting assembly further includes three sets of guide rods, which are fixedly installed between the two sets of mounting plates and arranged in a V-shape. The guide rods are located on the discharge side of the mounting cylinder.

[0011] Optionally, the control component includes a hollow disc, a sliding rod, a rotating block, a rotating rod, and a brake pad. The hollow disc is fixedly installed on the outside of the mounting block. The sliding rod is coaxially slidably sleeved on the outer end of the circular rod and slides through the interior of the hollow disc. A rotating block is fixed to the surface of the sliding rod. A rotating rod is hinged to the inner side of the rotating block. A brake pad is hinged to the inner side of the rotating rod. The brake pad is correspondingly disposed at the inner end face of the moving wheel.

[0012] Optionally, the hollow disk has an axially extending stabilizing groove inside, and stabilizing blocks are fixed on both sides of the rotating rod. The stabilizing blocks are embedded in the stabilizing groove and slide in cooperation with the stabilizing groove.

[0013] Optionally, a rotating wheel is fixedly installed on the outer end of the sliding rod, and a positioning bolt is threaded on the outer side of the hollow disc, with the screw end of the positioning bolt facing the inner end face of the rotating wheel.

[0014] Optionally, the four sets of moving wheels are rectangularly distributed at the four corners of the bottom of the film-laying machine. The two sets of moving wheels on the front side are connected to the lower part of the connecting block through a fixed frame, and the two sets of moving wheels on the rear side are connected to the synchronization component through a circular rod.

[0015] Optionally, a push-pull handle is fixedly installed on the front surface of the mounting bracket.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention uses a synchronization component to synchronously transmit the rotation of the rear moving wheels to the installation cylinder, ensuring precise matching between the unwinding speed of the HDPE geomembrane and the equipment's travel speed. This achieves a synchronized membrane laying effect where the travel distance and unwinding length correspond in real time. When operating in rugged terrain such as high-altitude mountains, even if the travel speed changes due to terrain undulations, the unwinding speed can be adjusted synchronously, effectively preventing the geomembrane from tensile breakage or loosening and wrinkling due to speed differences. This ensures the smoothness and construction quality of the membrane laying in complex terrains such as tailings dam access roads, steps, and drainage ditches.

[0017] This invention features a dual-limiting structure: first, an elastic membrane pressing structure composed of an arc-shaped plate, a first spring, and limiting rods, which maintains elastic contact with the geomembrane roll on the surface of the mounting cylinder, radially limiting the roll and preventing axial displacement or detachment of the membrane material during unwinding; second, three sets of guide rods arranged in a V-shape, which laterally limit and guide the released geomembrane, ensuring that the membrane material is laid along a preset route and accurately covers the work area. The dual-limiting mechanism works in tandem, making it particularly suitable for narrow and irregular working environments, effectively reducing the membrane laying deviation rate.

[0018] This invention integrates travel speed regulation and braking locking functions through a control component. Rotating the rotating wheel drives the linkage mechanism to push the brake pads to engage with the moving wheel. The travel speed is adjusted or emergency braking is achieved through friction, adapting to the needs of tailings dam steep slope operations and effectively preventing equipment from sliding downhill and losing control. With the help of positioning bolts, the braking state can be locked, stabilizing the rotation speed of the moving wheel and preventing the geomembrane from being suddenly pulled and broken due to excessive wheel speed. This greatly improves the safety and controllability of steep slope operations.

[0019] The stone-clearing slab of this invention is elastically suspended at the front of the mounting frame by a rectangular rod and a second spring. It can adaptively rise and fall with the terrain, and pre-push away and clear away gravel and debris on the membrane laying path during movement. This not only prevents gravel from jamming the walking mechanism and improves the equipment's ability to pass through rugged terrain, but also prevents gravel from puncturing the geomembrane, ensuring the integrity of the membrane laying. At the same time, the front moving wheels also achieve elastic cushioning through the second spring, further improving the equipment's adaptability to undulating terrain in plateau and mountainous areas.

[0022] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other. Example

[0023] like Figure 1 , Figure 2 As shown, this invention proposes a lightweight geomembrane laying machine suitable for plateau and mountainous terrain, comprising an installation cylinder 1, two sets of connecting blocks 2, an installation frame 3, two sets of installation plates 7, and two sets of installation blocks 8. The two sets of connecting blocks 2 are arranged symmetrically from left to right. The installation cylinder 1 is horizontally positioned, with its left and right ends penetrating the corresponding connecting blocks 2. The ends of the installation cylinder 1 are rotatably engaged with the connecting blocks 2, allowing the installation cylinder 1 to rotate freely around its own axis for mounting HDPE geomembrane rolls. The installation frame 3 has a portal frame structure, with its lower left and right sides fixedly connected to the top of the inner sides of the two sets of connecting blocks 2, forming the upper load-bearing frame of the equipment. The two sets of installation plates 7 are arranged symmetrically from left to right, fixedly installed on the inner walls of the two sets of connecting blocks 2, and located below the installation cylinder 1, for installing guide and limiting components. The two sets of installation blocks 8 are arranged symmetrically from left to right, fixedly connected to the rear lower part of the two sets of connecting blocks 2, for installing transmission and braking components. A push-pull handle 12 is fixedly installed on the front surface of the mounting bracket 3. The push-pull handle 12 extends laterally for the operator to hold and push the equipment forward.

[0024] like Figure 1 , Figure 2As shown, the traveling mechanism includes four sets of moving wheels 5, two sets of fixed frames 6, and circular rods 13. The four sets of moving wheels 5 are rectangularly distributed at the four corners of the bottom of the equipment, with the front two sets being driven wheels and the rear two sets being transmission wheels. The inner ends of the front two sets of moving wheels 5 are rotatably connected to the outer sides of the two sets of fixed frames 6, which are respectively positioned on the front side of the lower part of the two sets of connecting blocks 2, allowing the front moving wheels 5 to rotate freely around their own axes, realizing the driven travel and steering of the equipment. The inner ends of the rear two sets of moving wheels 5 are respectively fixedly connected to circular rods 13, which are arranged horizontally in the transverse direction. The inner ends of the circular rods 13 are rotatably engaged with the outer sides of the corresponding mounting blocks 8, allowing the rear moving wheels 5 to drive the circular rods 13 to rotate synchronously around their own axes, providing power input for synchronous unwinding. The rear two sets of moving wheels 5 are connected to the synchronous assembly 9 through the circular rods 13, realizing the synchronous linkage of travel and unwinding.

[0025] like Figure 1 , Figure 2 As shown, the elastic stone cleaning mechanism includes a stone cleaning plate 4, two sets of rectangular rods 14, two sets of circular blocks 16, and two sets of second springs 17. The stone cleaning plate 4 is horizontally positioned below the front of the equipment, in front of the front moving wheel 5. Vertically arranged rectangular rods 14 are fixedly installed on the left and right sides of the stone cleaning plate 4, with the upper part of the rectangular rods 14 extending upwards through the corresponding position of the mounting frame 3. The rectangular rods 14 are slidably engaged with the mounting frame 3, allowing the stone cleaning plate 4 to slide vertically up and down relative to the mounting frame 3. The two sets of circular blocks 16 are fixedly installed on the surfaces of the two sets of fixed frames 6, with their positions corresponding to the rectangular rods 14. The second spring 17 has two independent elastic support structures: one set of second spring 17 is located between the top of the circular stop 16 and the bottom of the mounting frame 3, with both ends of the spring fixedly connected to the top surface of the circular stop 16 and the bottom surface of the mounting frame 3, respectively, providing elastic cushioning for the front walking mechanism; the other set of second spring 17 is located between the top of the inner wall of the rectangular rod 14 and the bottom of the mounting frame 3, with both ends of the spring fixedly connected to the top surface of the inner wall of the rectangular rod 14 and the bottom surface of the mounting frame 3, respectively, providing elastic downward pressure and follow-up cushioning for the stone slab 4. The rectangular rod 14 adopts a hollow rod structure to provide installation and clearance space for the internal second spring 17. Through the elastic action of the two sets of second spring 17, both the stone slab 4 and the front moving wheel 5 can adaptively adjust their height according to the undulations of the ground, adapting to the rugged terrain of plateau and mountainous areas.

[0026] like Figure 1 , Figure 2As shown, the synchronization components 9 are located on the outside of the mounting block 8, and are connected between the mounting cylinder 1 and the circular rod 13. There are two sets, one on the left and one on the right, corresponding to the two sides of the equipment. Each set of synchronization components 9 includes a synchronization belt 91, a first synchronization pulley 92, and a second synchronization pulley 93. The first synchronization pulley 92 is fixedly installed on the outer end of the mounting cylinder 1 and rotates synchronously with the mounting cylinder 1; the second synchronization pulley 93 is fixedly installed on the surface of the circular rod 13, and the elliptical rod 13 rotates synchronously; the synchronization belt 91 is tensioned and fitted on the outside of the first synchronization pulley 92 and the second synchronization pulley 93, realizing the synchronous transmission connection between the two. Through the synchronization belt transmission structure, when the rear moving wheel 5 rotates, it can drive the circular rod 13 to rotate synchronously, and then drive the mounting cylinder 1 to rotate synchronously through the synchronization components 9, realizing the precise matching of the geomembrane unwinding speed and the equipment travel speed.

[0027] like Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, the limiting component 10 is disposed on the inner side of the mounting plate 7, and includes two parts: an elastic pressure membrane structure and a guide structure. The elastic pressure membrane structure includes an arc-shaped plate 101, two sets of rectangular blocks 102, a limiting rod 103, and a first spring 104, with one set on the left and one on the right corresponding to the two sides of the mounting cylinder 1. The two sets of rectangular blocks 102 are fixedly fixed to the inner sidewall of the connecting block 2 at intervals in the vertical direction. The limiting rod 103 slides vertically through the interior of the two sets of rectangular blocks 102 and can slide vertically up and down. The bottom of the limiting rod 103 is fixedly connected to the top of the arc-shaped plate 101, and the inner arc surface of the arc-shaped plate 101 faces the outer circumferential surface of the mounting cylinder 1. The first spring 104 is sleeved on the surface of the limiting rod 103. The top end of the first spring 104 is fixedly connected to the bottom of the upper rectangular block 102, and the bottom end of the first spring 104 is fixedly connected to the top of the arc-shaped plate 101. Under the elastic force of the first spring 104, the inner arc surface of the arc plate 101 always elastically presses against the outer side of the geomembrane roll on the surface of the mounting cylinder 1, radially limiting the membrane roll and preventing axial movement of the membrane material during unwinding. The guiding structure includes three sets of guide rods 105, all of which are horizontally arranged laterally and fixed at both ends between the left and right mounting plates 7 respectively. The three sets of guide rods 105 are arranged in a V-shape, forming a V-shaped guiding channel with the opening facing the mounting cylinder 1, and the guide rods 105 are located entirely on the discharge side of the mounting cylinder 1. After the geomembrane is released from the mounting cylinder 1, it passes through the V-shaped guide rods 105, achieving lateral limiting and guiding correction.

[0028] like Figure 2 , Figure 4 , Figure 5 , Figure 8As shown, the control components 11 are located on the outer side of the mounting block 8, corresponding to the circular rod 13. There are two sets, left and right, corresponding to the rear moving wheels 5 on both sides, used to realize speed regulation and braking locking. Each set of control components 11 includes a hollow disc 111, a sliding rod 112, a rotating block 113, a rotating rod 114, and a brake pad 115. The hollow disc 111 is a disc-shaped structure with one side open. Its inner end face is fixedly installed on the outer wall of the mounting block 8 and arranged coaxially with the circular rod 13. The sliding rod 112 is a hollow rod body that is coaxially slidably sleeved on the outer end of the circular rod 13. The sliding rod 112 slides through the interior of the hollow disc 111 and can slide back and forth along the axial direction of the circular rod 13. A rotating block 113 is fixedly mounted on the outer circumferential surface of the sliding rod 112. A rotating rod 114 is hinged to the inner side of the rotating block 113 via a hinge shaft. A brake pad 115 is hinged to the inner side of the rotating rod 114 via a hinge shaft. The friction surface of the brake pad 115 is positioned facing the inner end face of the corresponding moving wheel 5. When the sliding rod 112 moves axially, the rotating block 113 can drive the rotating rod 114 to swing, thereby pushing the brake pad 115 radially closer to or further away from the inner end face of the moving wheel 5.

[0029] like Figure 2 , Figure 4 , Figure 5 , Figure 8 As shown, the hollow disc 111 has an axially extending stabilizing groove 18 inside. Stabilizing blocks 19 are fixedly installed on both sides of the rotating rod 114. The stabilizing blocks 19 are embedded in the stabilizing groove 18 and slide in cooperation with it, providing radial guidance for the movement of the rotating rod 114 and preventing the brake pad 115 from shifting circumferentially. A rotating wheel 20 is fixedly installed on the outer end of the sliding rod 112. The rotating wheel 20 is located on the outer side of the hollow disc 111 for the operator to rotate. A positioning bolt 21 is threaded onto the outer wall of the hollow disc 111. The screw end of the positioning bolt 21 faces the inner end face of the rotating wheel 20. When the positioning bolt 21 is tightened, its end can press against the inner end face of the rotating wheel 20, locking the axial position of the sliding rod 112.

[0030] In this embodiment, the preparation before operation is as follows: the rotating wheel 20 is rotated in the opposite direction, which drives the sliding rod 112 to move axially outward. The rotating block 113 and the rotating rod 114 drive the brake pad 115 to completely separate from the inner end face of the rear moving wheel 5. Then, the positioning bolt 21 is tightened so that its end abuts against the rotating wheel 20, locking the position of the sliding rod 112 and preventing the equipment from moving accidentally.

[0031] The HDPE geomembrane roll is neatly mounted on the outer surface of the installation cylinder 1, ensuring that the roll is wrinkle-free, untangled, and tightly fitted to the outer wall of the installation cylinder 1; the arc plate 101 automatically fits the outer surface of the roll under the elastic force of the first spring 104, forming a radial limit on the roll.

[0032] The free end of the geomembrane is led out from below the installation cylinder 1 and pulled into the V-shaped channel formed by the three sets of guide rods 105. The position of the membrane is adjusted so that it passes through the guide rods 105 in the center, ensuring that there is no deviation or jamming during the unwinding process.

[0033] Positioning and commissioning: The operator holds the push-pull handle 12 and pushes the equipment to the starting position of the tailings dam walkway, steps or drainage ditch to be laid membrane, and adjusts the placement angle of the equipment so that the four sets of moving wheels 5 are all in stable contact with the ground.

[0034] Under the elastic force of the second spring 17, the bottom of the stone cleaning slab 4 automatically adheres to the ground, and the front moving wheel 5 is also elastically grounded through the second spring 17; when the terrain is uneven, the rectangular rod 14 can slide vertically along the mounting frame 3 to adaptively adjust the height of the stone cleaning slab 4, ensuring that the stone cleaning slab 4 is always in contact with the ground and has the ability to clean up gravel.

[0035] Synchronous membrane laying operation: Loosen the positioning bolt 21 to release the lock, and the operator pushes the equipment forward along the membrane laying route at a constant speed. The four sets of moving wheels 5 roll with the ground, driving the entire equipment forward. Among them, the rear moving wheel 5 drives the circular rod 13 to rotate synchronously around the axis; the second synchronous pulley 93 on the surface of the circular rod 13 rotates accordingly, driving the first synchronous pulley 92 to rotate synchronously through the synchronous belt 91, thereby driving the installation cylinder 1 to rotate at a constant speed, realizing the continuous unwinding of the HDPE geomembrane.

[0036] Since the unwinding power comes directly from the rotation of the traveling wheels, the unwinding linear speed of the geomembrane is always consistent with the traveling linear speed of the equipment. Even if the traveling speed changes due to terrain undulations, the unwinding speed can be adjusted synchronously, effectively preventing the geomembrane from stretching and breaking or becoming loose and wrinkled due to speed differences, and ensuring the flatness of the membrane.

[0037] During the process, the stone slab 4 moves forward close to the ground under the pressure of the second spring 17, pushing and clearing the gravel and debris on the membrane laying path to both sides, preventing the gravel from jamming the walking mechanism, and avoiding the gravel from puncturing the laid geomembrane, thus ensuring the integrity of the membrane material.

[0038] During the unwinding process, the arc plate 101 always elastically adheres to the surface of the membrane roll and gradually moves downward as the diameter of the membrane roll decreases, continuously limiting the axial movement of the membrane roll and preventing it from deviating and falling off. When the released geomembrane passes through the V-shaped guide rod 105, the guide rod corrects the membrane material laterally, ensuring that the membrane material is accurately laid along the preset route.

[0039] Speed ​​regulation and braking on steep slopes: When the equipment travels to a steep path or slope, if it is necessary to reduce the travel speed, the rotating wheel 20 can be rotated forward, causing the sliding rod 112 to slide axially inward along the circular rod 13; the sliding rod 112 causes the rotating block 113 to move inward synchronously, pushing the rotating rod 114 to move radially outward along the stabilizing groove 18, thereby causing the brake pad 115 to contact the inner end face of the rear moving wheel 5; the friction between the brake pad 115 and the moving wheel 5 reduces the rotation speed of the moving wheel, thereby adjusting the travel speed.

[0040] After adjusting to the target travel speed, tighten the positioning bolt 21 so that its end abuts against the inner end face of the rotating wheel 20, lock the axial position of the sliding rod 112, maintain a stable braking force, ensure that the equipment descends smoothly, avoid the equipment from slipping out of control due to the slope, and prevent the geomembrane from being suddenly pulled and broken due to excessive wheel speed.

[0041] If the film laying operation needs to be paused, continue to rotate the rotating wheel 20 to make the brake pad 115 fit tightly with the moving wheel 5 to achieve complete braking of the equipment. Then tighten the positioning bolt 21 to lock the braking state and prevent the equipment from slipping.

[0042] After the operation is completed, rotate the rotating wheel 20 in the opposite direction to separate the brake pad 115 from the moving wheel 5, and then push the equipment away from the operation area.

[0043] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
