Description

Technical Field

[0001] This utility model relates to the field of geomembrane welding machine technology, and belongs to a guiding device for a geomembrane welding machine. Background Technology

[0002] With the advancement of science and technology and the improvement of people's living standards, the construction industry is also developing rapidly. Geomembrane welding machines are important equipment used for welding plastic films. They are widely used in welding operations in fields such as roads, bridges, tunnels, water conservancy projects, sewage treatment, and landfills. However, since existing geomembrane welding machines on the market all require manual assistance, self-contained geomembrane welding devices are still a topic that needs innovation.

[0003] For example, a climbing welding machine with neat docking function for geomembrane docking, disclosed in the prior art (CN214056467U), includes a machine body, a limiting block, and a rotating shaft. A connecting shaft is connected inside the machine body, an inspection door is fixed on one side of the connecting shaft, a slider is provided on one side of the inspection door, a lever is connected to one side of the slider, a protective cover is connected to the top of the machine body, and a rotating rod is connected to one end of the protective cover.

[0004] Conventional geomembrane welding machines require manual operation. Without manual intervention, the machine cannot move in a straight line and fails to meet the requirement of uniform welding speed, resulting in material loss. Therefore, this invention provides a guiding device that enables the geomembrane welding machine to move in a straight line at a uniform speed. Utility Model Content

[0005] Therefore, this utility model provides a guiding device for a geomembrane welding machine to solve the problem of material loss caused by the inability of the welding machine to weld in a straight line in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A guiding device for a geomembrane welding machine includes a second limiting component. The second limiting component includes two wheel gears, both of which are mounted on the drive shaft of the geomembrane welding machine. Linear guide rails are provided at the bottom of each wheel gear, and racks meshing with the wheel gears are fixed at the top of each linear guide rail. A first limiting component is provided on each of the two linear guide rails. The first limiting component includes two support plates mounted on the drive shaft. A rotating rod passes through each of the two support plates, and a pulley is mounted on the rotating rod. Grooves are machined on the opposite sides of each of the two linear guide rails, and the pulleys slide within the grooves.

[0008] Furthermore, both wheel gears and two linear guides are made of PLA material through 3D printing. PLA material has good strength, which can ensure the strength of the wheel gears and linear guides. In addition, PLA material is biodegradable and has a small amount of environmental pollution, making it more environmentally friendly in practical applications.

[0009] Furthermore, both ends of the drive shaft and both ends of the rotating rod are provided with retaining rings. The retaining rings are used to limit the wheel gear and the limiting assembly to prevent them from falling off during operation, and at the same time facilitate disassembly and replacement.

[0010] Furthermore, a limiting component two is fixedly provided on the side of the two wheel gears that are close to each other. The limiting component two includes a limiting plate sleeved on the drive shaft. The two limiting plates contact the inner walls of the two linear guide rails respectively. The two limiting plates limit the two wheel gears, thereby preventing the wheel gears from deviating to the left or right and further improving the stability of the geomembrane welding machine in a straight line.

[0011] Furthermore, multiple fixing holes arranged in a circular array are machined on the outer wall surfaces of both limiting plates. Each fixing hole is equipped with a fastening bolt. The limiting plates are detachably fixed to the drive shaft by the fastening bolts. The use of multiple fastening bolts to connect the limiting plates and the drive shaft facilitates the subsequent disassembly and replacement of the limiting plates.

[0012] Furthermore, the two limiting plates are machined with the same number of mounting holes as the fixing holes on the side closest to each other. Each mounting hole is fixed with a spring pin, and each fastening bolt has a slot on its outer wall that matches the spring pin. One end of the spring pin is inserted into the slot. When the fastening bolt is tightened, the spring pin is inserted into the slot, which can reinforce the fastening bolt.

[0013] Furthermore, each fixing hole is threaded with a dust plug, which has a round hole. The dust plug can seal the fixing hole to prevent debris from clogging it and affecting the speed of subsequent disassembly and tightening of the bolts.

[0014] Furthermore, both limiting plates have threaded holes machined on their tops, and threaded rods are threaded into the threaded holes. Workers can remove the threaded rods and insert them into the round holes to facilitate quick unscrewing of the dust plugs for disassembly.

[0015] This utility model has the following advantages:

[0016] 1. This utility model uses a gear-wheel transmission system that meshes with a linear guide rack. This not only ensures the stability of the geomembrane welding machine's travel speed but also effectively avoids problems such as weak or excessive welding caused by uneven speed during manual operation. Furthermore, the gear-wheel transmission system, constrained by the limiting component, maintains full meshing with the rack, further improving the stability of linear travel. In addition, when operating on slopes, this meshing structure can also prevent the welding machine from sliding or falling due to gravity, significantly improving operational safety.

[0017] 2. The two limiting plates can limit the wheel gear and prevent it from deviating to the left or right, so that the wheel gear can move more stably in a straight line, thereby further ensuring that the geomembrane welding machine moves stably in a straight direction.

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] Refer to the instruction manual appendix Figures 1-5 This utility model provides a guiding device for a geomembrane welding machine, including two wheel gears 1, both of which are mounted on the drive shaft 2 of the geomembrane welding machine. The bottom of each wheel gear 1 is provided with a linear guide rail 3, and the top of each linear guide rail 3 is fixedly provided with a rack 4 that meshes with the wheel gear 1. Each linear guide rail 3 is provided with a limiting component 5, which includes two support plates 51 mounted on the drive shaft 2. A rotating rod 52 passes through each of the two support plates 51, and a pulley 53 is mounted on the rotating rod 52. Grooves 54 are machined on the opposite side of each of the two linear guide rails 3, and the pulley 53 slides in the groove 54.

[0032] In actual use, the workers first fix the two wheel gears 1 onto the drive shaft 2 of the geomembrane welding machine. After laying the two linear guide rails 3, the geomembrane welding machine is placed between the two linear guide rails 3, and the bottoms of the two wheel gears 1 are meshed with the two racks 4. Then, after connecting the two support plates 51 to the drive shaft 2, the geomembrane welding machine can be started. When the drive shaft 2 of the geomembrane welding machine rotates, it will drive the two wheel gears 1 to move synchronously. Since the wheel gears 1 and racks 4 are meshed, this not only ensures the stability of the geomembrane welding machine's speed, but also effectively avoids manual operation. The uneven speed during control can lead to problems such as weak welding or over-welding. At the same time, when working on slopes, this meshing structure can also prevent the geomembrane welding machine from sliding down due to gravity to a certain extent. In addition, the two wheel gears 1 are constrained by the pulley 53, the rotating rod 52 and the support plate 51, and can always maintain a fully meshed state with the rack 4, thereby ensuring that the geomembrane welding machine travels stably along a straight line without deviation, further improving the stability of the geomembrane welding machine's straight-line movement. When working on slopes, it can also prevent the geomembrane welding machine from falling due to its own weight, greatly improving the safety of the operation.

[0033] In this embodiment, the two wheel gears 1 and the two linear guide rails 3 are all made of PLA material by 3D printing. PLA material has good strength, which can ensure the strength requirements of the wheel gears 1 and the linear guide rails 3. In addition, the material is biodegradable and has a small amount of environmental pollution, so it is more environmentally friendly in practical applications.

[0034] In this embodiment, both ends of the drive shaft 2 and both ends of the rotating rod 52 are provided with retaining rings 6. The retaining rings 6 limit the wheel gear 1 and the limiting component 5, which can prevent them from falling off during the operation and facilitate disassembly and replacement.

[0035] Refer to the instruction manual appendix Figures 1-7 Limiting components 7 are fixedly provided on the side of the two gears 1 that are close to each other. The limiting components 7 include limiting plates 71 that are sleeved on the drive shaft 2. The two limiting plates 71 are in contact with the inner walls of the two linear guide rails 3 respectively. Multiple fixing holes 72 distributed in a ring array are machined on the outer wall surface of the two limiting plates 71. Each fixing hole 72 is provided with a fastening bolt 73. The limiting plates 71 are detachably fixed to the drive shaft 2 by the fastening bolts 73. The limiting plates 71 are connected to the drive shaft 2 by the fastening bolts 73, which facilitates subsequent disassembly and replacement.

[0036] The wheel gear 1 is connected to the drive shaft 2 of the geomembrane welding machine through the limiting plate 71. When the drive shaft 2 of the geomembrane welding machine drives the wheel gear 1 to rotate, since the diameter of the limiting plate 71 is larger than that of the wheel gear 1, the limiting plate 71 can limit the wheel gear 1 when it contacts the linear guide rail 3, preventing it from deviating to the left or right. This allows the wheel gear 1 to move more stably in a straight line, thereby further ensuring that the geomembrane welding machine moves stably in a straight direction.

[0037] Furthermore, each of the two limiting plates 71 has mounting holes 74 on its adjacent side, the same number as the fixing holes 72. A spring pin 75 is fixedly installed inside each mounting hole 74, and a slot 76 adapted to the spring pin 75 is machined on the outer wall of each fastening bolt 73. One end of the spring pin 75 is inserted into the slot 76. The insertion of the spring pin 75 into the slot 76 reinforces the fastening bolt 73, preventing it from loosening and affecting the stability of the wheel gear 1.

[0038] In addition, a dust plug 8 is threaded inside each fixing hole 72 to seal the fixing hole 72 and prevent dust. At the same time, a round hole 9 is machined on the dust plug 8, and a threaded hole 10 is machined on the top of each of the two limiting plates 71. A threaded rod 11 is threaded inside the threaded hole 10. The operator can take the threaded rod 11 out of the threaded hole 10 and insert it into the round hole 9 of the dust plug 8, which can facilitate the quick unscrewing of the dust plug 8 and realize the disassembly of the dust plug 8.

[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
