Description

Technical Field

[0001] The invention relates to the field of waterproof membrane laying equipment, in particular to an automatic waterproof membrane laying mechanical equipment suitable for complex terrain. Background Art

[0002] Waterproof membranes can be generally divided into three series according to the composition of raw materials: asphalt waterproof membranes, polymer modified asphalt waterproof membranes and synthetic polymer waterproof membranes. During construction, appropriate construction methods are selected according to different design requirements, materials and specific conditions of the project. Generally, there are self-adhesive method, hot melt cold adhesive method and wet laying method.

[0003] For example, the Chinese patent authorization announcement number CN220978873U discloses an auxiliary device for laying waterproof membranes, but it still has the following shortcomings in actual use:

[0004] When the waterproof membrane is being laid, the pressure roller will press the laid waterproof membrane tightly. When the pressure roller compacts the waterproof membrane, the pressure on the waterproof membrane at the overlap joints on both sides of the waterproof membrane is basically the same as the pressure on the middle waterproof membrane. However, the overlap joint is the weak link in the waterproof membrane, so higher compaction quality is required to ensure its sealing. Summary of the invention

[0005] In order to improve the problem that the pressure at the lap joints on both sides of the waterproof membrane is basically consistent with the pressure in the middle of the waterproof membrane, resulting in poor sealing, the present invention provides an automatic waterproof membrane laying mechanical equipment suitable for complex terrain.

[0006] The present invention provides an automatic waterproof membrane laying mechanical equipment suitable for complex terrain, which adopts the following technical solutions:

[0007] A mechanical device for automatically laying waterproof membranes suitable for complex terrains comprises a pressure roller assembly movably arranged at the front end of a frame, the pressure roller assembly comprising an adjusting roller mechanism fixedly connected to the two ends of a pressure roller body through a connecting column, the adjusting roller mechanism comprising a mounting plate fixedly connected to the outer ends of two connecting columns, a surface of the mounting plate being movably provided with a plurality of arcuate plates arranged in a ring array, a plurality of the arcuate plates being distributed into a cylindrical structure, a plurality of the arcuate plates being sleeved with elastic pressure rollers on the surfaces of the plurality of the arcuate plates, a gear one being rotatably installed at the center of a side of the mounting plate away from the connecting column, a plurality of the arcuate plates being movably connected to the gear one, a gear two being rotatably installed on the side of the mounting plate that meshes with the gear one, and when the gear two drives the gear one to rotate, a plurality of arcuate plates are opened to stretch the elastic pressure roller to enlarge its diameter, and a mounting cylinder is fixedly connected to the outer ring of a side of the mounting plate away from the connecting column.

[0008] By adopting the above technical solution and adjusting the design of the roller mechanism, that is, utilizing the meshing transmission of gear one and gear two to control the opening and closing of the arc plate, the diameter of the elastic pressure rollers at both ends can be adjusted, and the pressure on the lap joint of the waterproof membrane can be increased as required, thereby improving the compaction degree and ensuring the sealing and waterproofness of the lap joint of the waterproof membrane.

[0009] Preferably, a slide bar 1 is fixedly connected to the inner surfaces of the plurality of arc-shaped plates, a plurality of slide grooves 1 matching the shape of the slide bar 1 are opened on the surface of the mounting plate, and the plurality of slide bars 1 are respectively located in the plurality of slide grooves 1 and realize longitudinal sliding.

[0010] By adopting the above technical solution, the sliding rod 1 fixed to the inner surface of the arc plate cooperates with the sliding groove 1 on the surface of the mounting plate, so as to realize the stable sliding of the arc plate during the adjustment process. This design not only limits the lateral movement of the arc plate during adjustment, but also ensures its stable sliding in the longitudinal direction, thereby enhancing the structural stability of the entire pressure roller assembly during the adjustment process. The matching design of the sliding rod 1 and the sliding groove 1 helps to accurately control the opening degree of the arc plate, and then accurately adjust the diameter of the elastic pressure roller. Since the longitudinal sliding of the sliding rod 1 in the sliding groove 1 is limited, the arc plate can maintain a consistent motion trajectory when opening or closing, thereby improving the accuracy and reliability of adjustment.

[0011] Preferably, the lower ends of several of the slide rods are fixedly connected to connecting rods, several slide grooves 2 that are adapted to the shape of the connecting rods are provided on the side of the mounting plate away from the connecting column, several of the slide grooves 2 are connected to the corresponding slide grooves 1, and an arcuate slide groove that is adapted to the shape of the connecting rod is provided on the surface of the gear 1, and after passing through the corresponding slide grooves 2, several of the connecting rods are respectively located in the corresponding arcuate slide grooves and slide.

[0012] By adopting the above technical solution, the design of the connecting rod ensures the synchronization and stability of the arc plate during the adjustment process. When the gear rotates, it will guide the connecting rod through the arc groove, and then drive the arc plate to open or close in a coordinated manner. This design reduces the errors caused by asynchronous or unstable adjustment and improves the accuracy and reliability of the entire system.

[0013] By introducing the combination of connecting rods and arc-shaped slides, the adjustment range of the arc plate can be further increased. The shape of the arc-shaped slide allows the connecting rod to slide within a wider angle, thereby allowing the arc plate to open or close with a larger amplitude. This design improves the adaptability of the pressure roller assembly to waterproof membranes of different widths and increases the flexibility of the equipment.

[0014] Preferably, a rotating rod with one end movably penetrating the side wall of the mounting tube is fixedly connected to the center of the side surface of the gear 2, and a mounting hole matching the shape of the rotating rod is opened at the outer end of the mounting tube. The end of the rotating rod away from the gear 2 is rotatably installed in the mounting hole and fixedly connected to a rotating assembly, and the rotating assembly includes a sliding rod 2 fixedly connected to the end of the rotating rod away from the gear 2.

[0015] By adopting the above technical solution and providing a rotating assembly, it is convenient for an operator to manually drive the arc plate to adjust the arc plate.

[0016] Preferably, a ratchet one is fixedly connected to the outer ring of the end of the rotating rod away from gear two, a turning handle is movably sleeved on the surface of the sliding rod two, and a sliding groove three matching the shape of the sliding rod two is opened at the end of the turning handle close to the sliding rod two, the sliding rod two is located in the sliding groove three and realizes horizontal sliding, and a ratchet two meshing with the ratchet one is fixedly connected to the outer ring of the end of the turning handle close to the sliding rod two.

[0017] By adopting the above technical solution, ratchet one and ratchet two are not plugged in and engaged. At this time, when the handle is turned, the rotating rod will not rotate together. When the arc plate is needed and the rotating rod needs to be driven to rotate, the handle is pushed inward, and the handle slides relative to the slide rod two, so that the handle slides until the ratchet two and the ratchet one are plugged in and engaged. At this time, the handle can drive the rotating rod to rotate together.

[0018] When ratchet one and ratchet two are in a non-engaged state, even if the turning handle is subjected to external force, the turning rod cannot be driven to rotate, thereby avoiding accidental changes of the arc plate caused by misoperation or external force interference. This design improves the accuracy and stability of adjustment.

[0019] Preferably, a block is movably arranged on the inner wall of the third slide groove, and a fourth slide groove matching the shape of the block is provided on the inner wall of the third slide groove. The block is located in the fourth slide groove and realizes longitudinal sliding. A spring is fixed to the top of the block, and the top end is fixed to the top of the inner cavity of the fourth slide groove. Two grooves matching the shape of the block are provided on the surface of the second slide rod.

[0020] By adopting the above technical solution, the throttle slides to the desired position on the slide rod. When the block slides into the slot, the elastic force of the spring presses the block tightly into the slot, thereby preventing the throttle from sliding or rotating on its own when no external force is applied. This design improves the fixing stability of the throttle.

[0021] Preferably, the handlebar surface fixing sleeve is provided with a limiting plate.

[0022] By adopting the above technical solution, the limit plate is fixedly sleeved on the surface of the handle to limit the sliding range of the handle and ensure that the handle does not fall off the track during the sliding process.

[0023] Preferably, a slide groove five matching the shape of the limiting plate is provided on the inner wall of the mounting hole, and the limiting block is located in the slide groove five and realizes lateral sliding.

[0024] By adopting the above technical solution, the limit block is fixedly sleeved on the surface of the handle, and the limit block is matched with the sliding groove on the inner wall of the installation groove to ensure that the handle will not fall off the track during the sliding process.

[0025] Preferably, the elastic pressure roller is made of rubber.

[0026] By adopting the above technical solution, the rubber material is known for its excellent elasticity and resilience, which enables the elastic pressure roller to provide better fit and pressure distribution when compacting the waterproof membrane. The rubber pressure roller can adapt according to the surface shape of the waterproof membrane to ensure that the waterproof membrane is evenly compacted and avoid the generation of bubbles or wrinkles. The rubber material has good wear resistance and corrosion resistance, which means that the elastic pressure roller can maintain its shape and function during long-term use and is not easily corroded by wear or chemicals, which extends the service life of the pressure roller, reduces the frequency of replacement, and reduces maintenance costs.

[0027] Preferably, a rotating shaft is fixedly connected to the center of the outer ends of the two mounting tubes, a mounting frame is fixedly provided at the front end of the frame, and the ends of the two rotating shafts away from the mounting tubes are rotatably mounted on both sides of the mounting frame respectively.

[0028] By adopting the above technical solution, the matching design of the rotating shaft and the mounting frame enhances the structural stability of the entire pressure roller assembly. This design enables the pressure roller assembly to be more firmly fixed on the frame, reducing shaking or deviation during the paving process, thereby improving the paving accuracy and reliability.

[0029] In summary, the present invention includes at least one of the following beneficial technical effects:

[0030] 1. Through the design of the adjusting roller mechanism, the meshing transmission of gear 1 and gear 2 is used to control the opening and closing of the arc plate, so as to accurately adjust the diameter of the elastic pressure roller. This design enables the equipment to increase the pressure on the overlapping seams of the waterproof membrane according to demand, improve the compaction degree, and ensure the sealing and waterproof properties of the waterproof membrane. At the same time, the coordinated design of the slide bar 1 and the slide groove 1, the connecting rod and the slide groove 2, and the arc slide groove further enhances the stability and accuracy of the pressure roller assembly during the adjustment process.

[0050] The following is combined with Figure 1-Figure 11 The present invention is described in further detail.

[0051] The embodiment of the invention discloses a mechanical device for automatically laying a waterproof membrane suitable for complex terrain.

[0052] Reference Figure 1 , a mechanical device for automatically laying waterproof membranes suitable for complex terrains, including a mounting frame 7 fixedly mounted on the front end of a frame 1, a pressure roller assembly 6 movably arranged between the mounting frames 7, a guide mechanism 12 fixedly arranged at the bottom of the frame 1, two symmetrically arranged fixedly arranged fixedly arranged on the front side of the bottom of the frame 1, two symmetrically arranged universal wheels 8 fixedly arranged on the rear side of the bottom of the frame 1, and elastic pads 13 fixedly arranged between the universal wheels 8 and the top of the directional wheels 5 and the bottom of the frame 1. When encountering complex terrains, such as a road with a slope, the design of the elastic pad fixedly arranged between the universal wheels 8 and the top of the directional wheels 5 and the bottom of the frame 1 significantly enhances the adaptability and stability of the frame 1 in complex terrains.

[0053] Two vertical plates 3 are provided and are symmetrically arranged at the top center of the frame 1. A mounting groove 11 is opened in the center of the top of the side of the two vertical plates 3. The unwinding shaft 10 is arranged between the two mounting grooves 11, and the surface of the unwinding shaft 10 abuts against the inner wall of the mounting groove 11. The waterproof coil body 4 is movably sleeved on the surface of the unwinding shaft 10. A through hole for the waterproof membrane to pass through is opened on the top of the frame 1, and the direction handle 9 is fixedly arranged at the rear center of the top of the frame 1.

[0054] The heating assembly 2 is fixed on the frame 1, and the heating assembly 2 includes a liquefied gas tank 22. A fixing frame 21 is fixed on the top of the frame 1. The liquefied gas tank 22 is arranged at the bottom of the inner cavity of the fixing frame 21. The flame spray gun 23 is fixed at the bottom of the frame 1. A hose 24 is fixedly connected to the outlet end of the liquefied gas tank 22, and the end of the hose 24 away from the liquefied gas tank 22 is fixedly connected to the flame spray gun 23.

[0055] The frame 1 is the main structure of the whole equipment, used to support and connect other parts. The design of the fixed wheel 5 and the universal wheel 8 enables the frame 1 to move flexibly in the working area, which is convenient for the operator to adjust the position of the equipment according to the working requirements. The vertical plate 3 is symmetrically arranged at the top center of the frame 1, and the center of the top of the side is provided with a mounting groove 11.

[0056] The waterproofing coil body 4 is sleeved on the surface of the unwinding shaft 10, and the waterproofing coil body 4 is passed through the through hole. One end of the waterproofing coil body 4 passes through the through hole and bypasses the guide mechanism 12, and then it is attached to the surface of the pressure roller. The construction personnel pull the laying device through the direction handle 9 to lay the waterproofing coil body 4, and the pressure roller compacts the waterproof membrane to prevent wrinkles or skewness when laying the waterproofing coil. At the same time, the gas valve of the liquefied gas tank 22 is opened, and the flame spray gun 23 is set to evenly heat the waterproofing coil body 4 with flames, thereby improving the laying effect. The directional wheel 5 and the universal wheel 8 are connected to the bottom of the frame 1

[0057] Reference Figure 2 , Figure 3 The pressure roller assembly 6 includes connecting columns 64 fixedly connected to the two ends of the pressure roller body 61, and an adjusting roller mechanism 62 is fixedly arranged at one end of the connecting columns 64 away from the pressure roller body 61. The adjusting roller mechanism 62 includes a mounting plate 621 fixedly connected to the end of the connecting column 64 away from the pressure roller body 61, and a mounting cylinder 624 is fixedly connected to the outer ring of the mounting plate 621 away from the connecting column 64. A rotating shaft 63 is fixedly connected to the center of one end of the mounting cylinder 624 away from the mounting plate 621 at both ends, and one end of the rotating shaft 63 at both ends away from the mounting cylinder 624 is rotatably connected to the side plates on both sides of the mounting frame 7 respectively.

[0058] Reference Figure 4-Figure 7 , a plurality of arc-shaped plates 622 are arranged in a circular manner with equal spacing and distributed into a cylindrical structure, a slide rod 626 is fixedly connected to the center of the inner surface of the arc-shaped plate 622, a plurality of slide grooves 627 are opened on the surface of the mounting plate 621, a plurality of slide rods 626 are respectively located in the plurality of slide grooves 627, and the surface of the slide rod 626 abuts against the inner wall of the slide groove 627, a connecting rod 628 is fixedly connected to the center of the lower end of the side of the plurality of slide rods 626 away from the connecting column 64, and the mounting plate 621 is away from the connecting column A plurality of slide grooves 6212 are provided on one side of 64, and the plurality of slide grooves 6212 are connected with the corresponding slide grooves 1 627. A plurality of connecting rods 628 are located in the corresponding slide grooves 6212 and their surfaces are in contact with the inner wall of the slide grooves 6212. The length of the slide grooves 6212 is greater than the diameter of the connecting rods 628, so that the connecting rods 628 can slide longitudinally when located in the slide grooves 6212. An elastic pressure roller 625 made of rubber is movably sleeved on the surface of the plurality of arc plates 622.

[0059] A gear 623 is rotatably mounted on the central side of the mounting plate 621 away from the connecting column 64. A plurality of arc-shaped grooves 629 are provided on the surface of the gear 623. One end of a plurality of connecting rods 628 away from the sliding rod 626 extends into the corresponding arc-shaped grooves 629. The surfaces of the connecting rods 628 abut against the inner walls of the arc-shaped grooves 629. The arc length of the arc-shaped grooves 629 is greater than the diameter of the connecting rods 628, so that the connecting rods 628 can slide in the arc-shaped grooves 629. The end of the connecting rod 628 away from the sliding rod 1 626 is fixedly connected to the limit block 6214, and the diameter of the limit block 6214 is larger than the diameter of the connecting rod 628 to prevent the connecting rod 628 from escaping from the arc-shaped sliding groove 629. The side of the mounting plate 621 away from the connecting column 64 is rotatably connected to the gear 2 6210, and the gear 2 6210 is meshed with the gear 1 623. The center of the side of the gear 2 6210 away from the mounting plate 621 is fixedly connected to the rotating rod 6211.

[0060] When the opening degree of the arc plate 622 needs to be adjusted, the rotating rod 6211 is rotated to drive the gear 2 6210 to rotate. Since the gear 2 6210 is meshed with the gear 1 623, the gear 1 623 will also rotate accordingly. As the gear 1 623 rotates, the arc groove 629 on its surface will drive the connecting rod 628 to slide along the arc path. Since one end of the connecting rod 628 is fixed to the slide rod 1 626, the slide rod 1 626 will move in the slide groove 1 627 accordingly, and the connecting rod 628 will also rotate in the arc groove 1 627. The rod 628 will also slide longitudinally in the second slide groove 6212. This movement and sliding will change the relative position between the arc plates 622, thereby adjusting the opening degree of the arc plates 622. When the gear 1 623 rotates to the required position, the opening degree of the arc plates 622 reaches the expected value. The arc plate 622 will expand the elastic pressure roller 625 on its surface, and then the diameter of the elastic pressure roller 625 will increase, thereby increasing the pressure on the lap joint of the waterproof membrane, improving the compaction degree, and ensuring the sealing and waterproof properties of the waterproof membrane.

[0061] During the adjustment process, the limit block 6214 plays an important locking and stabilizing role. Since the diameter of the limit block 6214 is larger than the diameter of the connecting rod 628, it can prevent the connecting rod 628 from accidentally falling out of the arc-shaped slide groove 629. At the same time, the limit block 6214 also increases the contact area between the connecting rod 628 and the arc-shaped slide groove 629, thereby improving the stability and reliability of the connection. In addition, the design of slide groove 1 627 and slide groove 2 6212 also ensures the stability and accuracy of slide rod 1 626 and connecting rod 628 during movement. They limit the movement direction and range of slide rod 1 626 and connecting rod 628, thereby preventing equipment damage or inaccurate adjustment caused by excessive movement.

[0062] Reference Figure 8-Figure 11A mounting hole 6216 is provided on one side of the mounting cylinder 624 away from the mounting plate 621. One end of the rotating rod 6211 away from the gear 2 6210 is connected to the inner wall of the mounting hole 6216 through a bearing or a similar mechanism to reduce friction and improve the smoothness of rotation. A rotating assembly 65 is provided on one end of the rotating rod 6211 away from the gear 2 6210. The rotating assembly 65 includes a sliding rod 651 fixedly connected to one end of the rotating rod 6211 away from the gear 2 6210. The sliding rod 651 is located in the mounting hole 6216. One end of the turning handle 6510 is located in the mounting hole 6216. A slide groove three 655 is opened at this end of 510, and the slide rod two 651 is located in the slide groove three 655 and its surface abuts against the inner wall of the slide groove three 655. At the same time, the surface of the turning handle 6510 abuts against the inner wall of the mounting hole 6216. The ratchet one 652 is fixedly connected to the outer ring of the end of the rotating rod 6211 away from the gear two 6210, and the ratchet two 653 is fixedly connected to the outer ring of the end of the turning handle 6510 close to the slide rod two 651. The ratchet one 652 and the ratchet two 653 are nested with each other in a staggered manner, wherein the teeth of the ratchet one 652 correspond to the gap between the teeth of the ratchet two 653, forming a staggered plug-in structural relationship.

[0063] The limit plate 654 is fixedly mounted on the surface of the turning handle 6510 to limit the sliding range of the turning handle 6510 in the sliding groove 5 6215 of the mounting hole 6216.

[0064] A slide groove four 657 is provided on the inner wall of the slide groove three 655, and the block 656 is located in the slide groove four 657, and the bottom (i.e. the wide side) of the block 656 is in close contact with the inner wall of the slide groove four 657. The height of the slide groove four 657 is greater than the height of the block 656, so that the block 656 can slide longitudinally in the slide groove four 657. The shape of the block 656 is an isosceles trapezoid, and a spring 658 is fixed to the top of the block 656. The top end of the spring 658 is fixed to the top of the inner cavity of the slide groove four 657, and two slots 659 that match the shape of the block 656 are provided in parallel on the surface of the slide rod two 651.

[0065] In the initial state, the block 656 is engaged in the slot 659 away from the ratchet wheel 1 652. At this time, the ratchet wheel 1 652 and the ratchet wheel 2 653 are not plugged in and meshed. At this time, when the turning handle 6510 is turned, the rotating rod 6211 will not rotate together. When the arc plate 622 needs to be adjusted and the rotating rod 6211 needs to be driven to rotate, the turning handle 6510 is pushed inward, and the turning handle 6510 slides relative to the sliding rod 2 651. At this time, it is engaged in the slot 659 The beveled edge of the block 656 can gradually guide the block 656 to leave the slot 659. When the turning handle 6510 slides to the point where the ratchet wheel 2 653 is plugged and engaged with the ratchet wheel 1 652, the block 656 is just engaged in the other slot 659 under the action of the spring 658. The turning handle 6510 can drive the rotating rod 6211 to rotate together, thereby adjusting the opening degree of the arc plate 622 and adjusting the diameter of the elastic pressure roller 625 to an appropriate size.

[0066] When the diameter of the elastic pressure roller 625 is adjusted to a suitable size, the turning handle 6510 is pulled outward. Similarly, the card block 656 slides out of the slot 659 close to the ratchet wheel 1 652 and is engaged in another slot 659 to fix the turning handle 6510 in this position. At this time, the ratchet wheel 2 653 is no longer plugged and meshed with the ratchet wheel 1 652. When the ratchet wheel 1 652 and the ratchet wheel 2 653 are in a non-meshing state, even if the turning handle 6510 is acted upon by an external force, it cannot drive the rotating rod 6211 to rotate, thereby avoiding accidental changes of the arc plate 622 due to misoperation or external interference. The limit plate 654 is adapted to the slide groove 5 6215 on the inner wall of the mounting hole 6216 to ensure that the turning handle 6510 will not fall off the track during the sliding process.

[0067] The implementation principle of an automatic waterproof membrane laying mechanical equipment suitable for complex terrain in an embodiment of the present invention is as follows: the equipment body is supported by a frame 1, on which directional wheels 5 and universal wheels 8 are installed to achieve flexible movement; the waterproof membrane body 4 is sleeved on the unwinding shaft 10 and pulled out through the through hole on the top of the frame 1, and contacts with the pressure roller assembly 6 after bypassing the guide mechanism 12; the construction personnel pull the equipment through the direction handle 9, so that the waterproof membrane is laid flatly under the compaction action of the pressure roller. The design of the pressure roller assembly 6 is unique, including adjustable arc plates 622, on which elastic pressure rollers 625 are sleeved. The opening degree of the arc plates 622 can be adjusted by rotating the rod 6211. One end of the rotating rod 6211 is connected to the gear 2 6210. By rotating the gear 2 6210, the sliding rod 1 626 and the connecting rod 628 on the arc plates 622 can be driven to move in the preset sliding groove, thereby changing the relative position of the arc plates 622 to achieve the purpose of adjusting the opening degree. In order to facilitate operation, the rotating rod 6211 The other end is provided with a rotating assembly 65, including a ratchet mechanism and a slidable turning handle 6510. In the initial state, the ratchet mechanism is not engaged, and the turning handle 6510 can rotate freely without driving the rotating rod 6211. When the arc plate 622 needs to be adjusted, the turning handle 6510 is pushed to engage it with the ratchet mechanism, and then the turning handle 6510 is rotated to drive the rotating rod 6211 and the gear 2 6210 to adjust the opening degree of the arc plate 622. After the adjustment is completed, the turning handle 6510 is pulled out to disengage the ratchet mechanism and lock the current position.

[0068] In addition, the equipment is also equipped with a heating component 2, including a liquefied gas tank 22 and a flame spray gun 23, which is used to uniformly heat the waterproof coiled material during the laying process to improve the laying effect.

[0069] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
