Description

Technical Field

[0001] The utility model relates to the technical field of laying devices, in particular to a high-efficiency geomembrane laying device. Background Art

[0002] Geomembrane is a waterproof barrier material with high molecular polymer as the basic raw material. It has excellent resistance to environmental stress cracking, low temperature resistance, aging resistance, corrosion resistance and other properties. In many fields such as water conservancy projects, environmental protection projects, and transportation projects, geomembranes are widely used to prevent liquid leakage and isolate different media. Since geomembranes are usually large in area and soft in texture, manual laying efficiency is low and it is difficult to ensure laying quality. Therefore, special laying devices are needed to improve laying efficiency and quality.

[0003] In the existing geomembrane laying technology, the common laying device is generally composed of a frame body, several rollers and a simple traction mechanism. The frame body is used to support and fix the entire device. The rollers are installed under the frame. By rolling, the friction between the device and the ground is reduced, making it easier for the device to move on the ground. The traction mechanism is usually a rope or a pull rod connected to the frame. The device is pulled forward by human or mechanical force to achieve the laying of the geomembrane. During the laying process, the device mainly relies on the rolling of the rollers and the pulling force of the traction mechanism to move, gradually unfolding the geomembrane and laying it on the ground.

[0004] When the existing geomembrane laying device is not in use, the roller is in direct contact with the ground. Due to the complex ground environment and the presence of various impurities, gravel, etc., the roller is easily worn even when not in operation. In the long run, the wear of the roller will reduce the service life of the equipment and increase construction costs. It will also affect the efficiency and quality of geomembrane laying. Therefore, an efficient geomembrane laying device is proposed to solve the above problems. Utility Model Content

[0022] The utility model has the following beneficial effects:

[0023] 1. In the utility model, the pin is first pulled out from the fixing plate to cancel the fixed state with the fixing plate.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 2 The utility model provides an embodiment of an efficient geomembrane laying device, including a trolley 1, which is used to facilitate the movement and transportation of the equipment and provide a foundation for installation and support of other components. A first winding roller 2 is provided inside the trolley 1, which is used to wind up geomembrane and other materials, and plays an important storage and release role in the laying process. A fixed plate 3 is fixedly connected to the bottom of the trolley 1, which is used to provide a stable installation position for subsequent components, ensuring that the connection between the components is firm and reliable. The fixed plate 3 is rotatably connected to the internal rotation shaft 4, which is used to connect and transmit kinetic energy so that the support rod 5 can rotate around it, thereby realizing different working states of the equipment. The external rotation shaft 4 is fixedly connected to the support rod 5, which is used to support the roller 6 and the turning shovel 15, ensuring that these components are in stable position during work. Rollers 6 are provided on the side walls of the support rod 5, and connecting rods 7 are rotatably connected between the support rods 5. An adjustment mechanism is provided on the side walls of the fixed plate 3, and a side plate 8 is fixedly connected to the inside of the trolley 1, and a disassembly mechanism is provided inside the side plate 8. Mechanism; The adjustment mechanism includes a disc 9, which is used to rotate with the rotation of the shaft 4 and cooperate with the ring 10 to adjust the state of the device. The disc 9 is fixedly connected to the side wall of the shaft 4. The side wall of the disc 9 is fixedly connected with a ring 10, which is used to provide a sliding track for the latch 11 to ensure that the movement direction of the latch 11 is accurate. The latch 11 is slidably connected inside the ring 10, and the outer sleeve of the latch 11 is provided with a first spring 12. The outer side of the latch 11 is fixedly connected with a gasket 13, which is used for buffering and limiting to prevent The first spring 12 deviates during the movement, and a tiller 15 is fixedly connected to the side wall of the support rod 5, which is used to till the soil during the laying of the geomembrane, and to cover the outside of the laid geomembrane with a layer of sand to prevent the geomembrane from moving easily. One end of the first spring 12 is fixedly connected to the side wall of the ring 10, and the other end of the first spring 12 is fixedly connected to the side wall of the gasket 13. A hole 14 is opened through the inside of the fixing plate 3, and the pin 11 is slidably connected to the inside of the hole 14, and the ring 10 is aligned with the hole 14;

[0033] When the device is used, the latch 11 is pulled out from the fixing plate 3. At this time, the first spring 12 is stretched and deformed by the force. The latch 11 plays a key role in fixing and releasing the fixation. When the latch 11 is inserted into the fixing plate 3, it can ensure the stability of the device during use; when the latch 11 is pulled out, the fixed state can be released, which is convenient for subsequent operations. The first spring 12 plays the role of providing a reset force. When the latch 11 is pulled out, it stretches and can drive the latch 11 to reset, ensuring that the device can be reliably fixed when not in use. When the latch 11 moves into the ring 10, the fixed state between it and the fixing plate 3 is cancelled. At this time, the connecting rod 7 is lifted upward. The connecting rod 7 serves as an operating component, which is convenient for the user to apply force to lift the device and adjust its position. The support rod 5 is driven to rotate by the rotating shaft 4, and the roller 6 moves accordingly. At this time, the disc 9 and the ring 10 also rotate accordingly. The rotating shaft 4 plays the role of connecting and transmitting motion, so that the rotation of the support rod 5 can be carried out smoothly, thereby driving the roller 6 to move its position. 5 plays a supporting role for the roller 6, ensuring that the roller 6 can roll stably on the ground, facilitating the movement of the equipment. The roller 6 makes the equipment more convenient and labor-saving when it needs to be moved. The disc 9 and the ring 10, on the one hand, play an auxiliary fixing role during the operation of the equipment, and on the other hand, cooperate with the latch 11 to realize the fixing and releasing function of the equipment. When it is moved to the appropriate position, the latch 11 is released, and the first spring 12 loses the force it receives and resets, driving the latch 11 to re-insert into the fixing plate 3 through the hole 14, fixing the disc 9. Through the rotating shaft 4, the support rod 5 and the roller 6 are also fixed, so that the roller 6 and the tilling shovel 15 are separated from the ground. When the equipment is not in use, the roller 6 and the tilling shovel 15 are prevented from being worn on the ground, which reduces their service life. The tilling shovel 15 is the main working part of the equipment. When the equipment is in use, it is used to turn the soil and press the soil on the covering film 23 to prevent the covering film 23 from moving easily. Through the above operation, the roller 6 and the tilling shovel 15 can be effectively protected and the service life of the equipment can be extended.

[0034] Reference Figure 3-Figure 4The disassembly mechanism includes a turntable 16, which is used to provide a mounting and support basis for the second winding roller 22, so that the second winding roller 22 can rotate stably, which is convenient for the winding and releasing of the coating 23. The turntable 16 is rotatably connected to the inside of the side plate 8. A second winding roller 22 is provided between the turntables 16. The coating 23 is provided outside the second winding roller 22. The side wall of the second winding roller 22 is fixedly connected to a second sleeve 19, which is used to provide a sliding track and support for the first sleeve 18, ensuring that the movement direction of the first sleeve 18 is accurate and stable. The inside of the second sleeve 19 A first sleeve 18 is slidably connected, and a second spring 20 is provided inside the first sleeve 18, which is used to provide a certain elastic force to keep the block 17 and the turntable 16 in a locked state. One end of the second spring 20 is fixedly connected to the inside of the first sleeve 18, and the other end of the second spring 20 is fixedly connected to the inside of the second sleeve 19. A pulling block 21 is fixedly connected to the side wall of the first sleeve 18, which is used to apply force to pull the first sleeve 18 to disassemble the second winding roller 22. A blocking block 17 is fixedly connected to the side wall of the first sleeve 18, and the blocking block 17 is engaged with the turntable 16.

[0035] When the device needs to be repaired or replaced after a period of use, the second winding roller 22 needs to be repaired or replaced by pinching the pull block 21 and squeezing it toward the middle. The pull block 21 serves as an operating component, which is convenient for applying force for subsequent operations and is convenient for accurate grasping and applying force, driving the first sleeve 18 to slide toward the inside of the second sleeve 19. The second spring 20 is deformed by the force at this time. The first sleeve 18 and the second sleeve 19 cooperate with each other to play a guiding and accommodating role, ensuring that the movement direction of the components is accurate and stable during operation. The second spring 20 provides a certain elastic force in the normal state to keep the block 17 in a specific position and play a fixing role. When external force is applied, deformation occurs, storing elastic potential energy, providing power for the subsequent disengagement of the block 17, thereby causing the block 17 to disengage from the turntable 16. At this time, the second winding roller 22 can be removed for maintenance or replacement. The block 17 mainly plays the role of fixing the second winding roller 22 to ensure that the position of the second winding roller 22 is stable during the operation of the equipment and does not loosen or deviate. The turntable 16 provides a basis for installation and support for the second winding roller 22, and cooperates with the block 17 to ensure the normal operation of the second winding roller 22. Through the above operations, the second winding roller 22 can be easily repaired or replaced to ensure the continuous and stable operation of the equipment.

[0036] Working principle: After using the device, the latch 11 is pulled out from the fixing plate 3. At this time, the first spring 12 is stretched and deformed by the force. When the latch 11 moves into the ring 10, the fixed state between the latch and the fixing plate 3 is cancelled. At this time, the connecting rod 7 is held and lifted up to drive the support rod 5 to rotate through the rotating shaft 4, and the roller 6 moves accordingly. At this time, the disc 9 and the ring 10 also rotate accordingly. When it moves to the appropriate position, the latch 11 is released, and the first spring 12 loses the force it receives and resets, driving the latch 11 to be re-inserted into the fixing plate 3 through the hole 14, fixing the disc 9. Through the rotating shaft 4, the support rod 5 and the roller 6 are also fixed, so that the roller 6 and the turning shovel 15 are separated from the ground. When the device is not in use, the roller 6 and the turning shovel 15 are prevented from being worn on the ground, which reduces the service life.

[0037] When the device has been used for a period of time and the second winding roller 22 needs to be repaired or replaced, pinch the pull block 21 and squeeze it toward the middle, driving the first sleeve 18 to slide toward the inside of the second sleeve 19. The second spring 20 is then deformed by the force, causing the block 17 to detach from the turntable 16. At this time, the second winding roller 22 can be removed for repair or replacement.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
