Description

Technical Field

[0001] This application relates to the field of waterproof membrane laying, and in particular to a tunnel waterproof membrane laying device. Background Technology

[0002] The installation of waterproof membranes in tunnels is a crucial step in ensuring structural stability and safety during tunnel construction. In recent years, with the development of automation and intelligent technologies, equipment for waterproof membrane installation has gradually evolved towards high efficiency, precision, and intelligence. Related research has been conducted both domestically and internationally in this field. Modern tunnel engineering has widely adopted waterproof membrane installation trolleys for waterproof membrane installation and welding operations. Some high-end equipment has integrated preliminary automatic control functions, but most equipment still mainly relies on manual operation, making it difficult to cope with complex and ever-changing on-site construction environments. A large number of construction problems urgently need to be solved.

[0003] Currently, when laying waterproof membranes in tunnels, the membranes are laid manually inside the tunnel, resulting in low laying efficiency. Furthermore, workers cannot accurately control the length of the membrane each time it is laid. When the membrane is laid too long at once and welded to the tunnel, large areas of wrinkles and gaps appear between the membrane and the tunnel wall, leading to errors and incomplete laying of the waterproof membrane. Utility Model Content

[0004] To address the issue of large gaps between the waterproofing membrane and the tunnel wall, this application provides a tunnel waterproofing membrane laying device.

[0005] The tunnel waterproof membrane laying device provided in this application adopts the following technical solution:

[0006] A tunnel waterproof membrane laying device includes a laying frame, with hydraulic cylinders rotatably connected to both sides of the laying frame. A drive motor for driving the hydraulic cylinders to rotate is fixedly connected to one side of the laying frame. A connecting plate is fixedly connected to the output ends of the two hydraulic cylinders. A drum is rotatably connected to one side of the connecting plate. Fixed boxes are fixedly connected to both sides of the connecting plate. A fourth slide rod is fixedly connected to each of the two fixed boxes. A connecting block that slides on the fourth slide rod is slidably connected to each of the two fixed boxes. A fourth spring sleeved on the fourth slide rod is fixedly connected between each of the two connecting blocks and the fixed boxes. A rotating column is rotatably connected to one side of each of the two connecting blocks. A rolling wheel is fixedly connected to one side of each of the two rotating columns.

[0007] A rotating block is fixed to one side of each of the two rotating columns, a connecting frame is fixed to one side of each of the two connecting blocks, a third slide rod is fixed to one side of each of the two connecting frames, a button is fixed to one side of each of the two third slide rods, a slider is slidably connected to one side of each of the two third slide rods, and a third spring sleeved on the third slide rod is fixed between each of the two sliders and the connecting frame.

[0008] By adopting the above technical solution, platforms for standing are provided on both sides and the top of the laying frame. The drive motor is a large geared motor, and the hydraulic cylinder is used to adjust the distance between the connecting plate and the tunnel. The waterproof membrane is unfolded by moving the roller through the connecting plate. The connecting block slides in the fixed box and compresses the fourth spring through the fourth slide rod, so that the rolling wheel moves with the connecting block through the rotating column, allowing the rolling wheel to roll against the inner wall of the tunnel. The connecting frame moves together with the connecting block. The rotation of the rotating column causes the rotating block to rotate, which can push the slider to move. The slider slides on the third slide rod and compresses the third spring. The slider will press the button to stop the drive motor. The required length of waterproof membrane can then be laid and welded and fixed in sections, reducing the non-adhesive parts between the waterproof membrane and the inner wall of the tunnel, reducing the fixing gap between the waterproof membrane and the inner wall of the tunnel, and reducing the situation where the waterproof membrane wrinkles during welding due to laying too long at one time.

[0009] Preferably, a sliding box is fixedly connected to both sides of the connecting plate, a first sliding rod is fixedly connected to each of the two sliding boxes, and a shovel blade that slides on the first sliding rod is slidably connected to both of the two sliding boxes. A first spring sleeved on the first sliding rod is fixedly connected between the shovel blade and the sliding box. A limiting cylinder is provided on both sides of the shovel blade, and a limiting piece for sliding in the limiting cylinder is fixedly connected to one end of each of the two first sliding rods.

[0010] By adopting the above technical solution, the shovel rotates inside the tunnel to flatten the tunnel wall. The shovel slides in the sliding box and compresses the first spring through the first slide rod. The shovel slides in the limiting cylinder through the limiting plate to make the shovel slide at the upper limit of the first slide rod to prevent the shovel from sliding out of the sliding box and to prevent the shovel from making hard contact with the tunnel and damaging the shovel.

[0011] Preferably, cylinders are fixedly connected to both sides of the laying frame, and pressing plates for fixing the waterproof board are fixedly connected to the output ends of the cylinders on both sides.

[0012] By adopting the above technical solution, multiple grooves are provided on one side of the pressing plate to increase friction, and the cylinder pushes the pressing plate to press the waterproof membrane onto the inner wall of the tunnel for fixation.

[0013] Preferably, both sides of the drum are rotatably connected to a fixing block that slides with the connecting plate, and both sides of the connecting plate are threadedly connected to fixing bolts that are threadedly connected to the fixing blocks.

[0014] By adopting the above technical solution, the roll can slide between the U-shaped plates of the connecting plate via the fixing block, and the fixing bolts can be screwed into the fixing block and the connecting plate to fix the fixing block and the connecting plate, thereby replacing the roll and the waterproof plate.

[0015] Preferably, a threaded block is slidably connected to one side of the connecting plate, a telescopic rod is fixedly connected to one side of the threaded block, a second motor is fixedly connected to the output end of the telescopic rod, and an ultrasonic welding gun is fixedly connected to the output end of the second motor.

[0016] By adopting the above technical solution, the welding height of the ultrasonic welding gun is adjusted by the telescopic rod, the welding angle of the ultrasonic welding gun is adjusted by the second motor, and the threaded block is moved so that the ultrasonic welding gun can weld and fix the waterproof membrane to the inner wall of the tunnel.

[0017] Preferably, a threaded rod that is threadedly connected to the threaded block is rotatably connected to one side of the connecting plate, a second gear is fixedly connected to one side of the threaded rod, a first motor is fixedly connected to one side of the connecting plate, and a first gear that meshes with the second gear is fixedly connected to the output end of the first motor.

[0018] By adopting the above technical solution, the first motor is started and the threaded rod is rotated by the meshing of the first gear and the second gear. The rotation of the threaded rod causes the threaded block to slide on the connecting plate, thereby moving the ultrasonic welding gun to weld the waterproof membrane.

[0019] Preferably, a limiting groove is provided on one side of the connecting plate, and a limiting disc that is slidably connected to the limiting groove is fixed on one side of the threaded block.

[0020] By adopting the above technical solution, the limiting plate penetrates the connecting plate and has a protruding block that matches the limiting groove. The length of the limiting groove is less than that of the connecting plate, so that the limiting plate, along with the threaded block, slides on the upper limit of the connecting plate.

[0021] Preferably, a connecting shell is fixedly connected to one side of the connecting plate, and a take-up box is slidably disposed inside the connecting shell. The two ends of the take-up box are fixedly connected to the limiting plate and the connecting shell, respectively.

[0022] By adopting the above technical solution, the cable retractor is a nylon tank chain used to bundle up the cables and pipes for easy movement, and the connecting shell can protect the cables and pipes inside the cable retractor.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The waterproof membrane is fixed to one end inside the tunnel by pressing the plate. Then, the roller is moved to lay the waterproof membrane inside the tunnel. The length of the unfolded waterproof membrane is controlled by the rolling rollers rolling on the inner wall of the tunnel. The waterproof membrane is laid in sections inside the tunnel. The inner wall of the tunnel is leveled by a scraper to ensure better adhesion of the waterproof membrane to the tunnel. The pressing strip is used to press the waterproof membrane tightly onto the roller. This allows the equipment to better lay the waterproof membrane in tunnels of different sizes and types, preventing the waterproof membrane from being difficult to weld and fix to the inner wall of the tunnel due to excessive unfolding. It also reduces the problems of wrinkles and insufficient adhesion between the waterproof membrane and the tunnel.

[0025] 2. The waterproof membrane is welded and fixed inside the tunnel by moving the ultrasonic welding gun on the connecting plate. The angle of the ultrasonic welding gun is adjusted by the second motor so that the ultrasonic welding gun can perform welding better. The wiring and pipes required for welding by the ultrasonic welding gun are protected by the connecting shell and the take-up box to ensure that the welding work is carried out normally during the laying of the waterproof membrane.

[0036] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0037] This application discloses a tunnel waterproofing membrane laying device.

[0038] Reference Figures 1 to 7 A tunnel waterproof membrane laying device includes a laying frame 1. Hydraulic cylinders 3 are fixedly installed on both sides below the laying frame 1. A drive motor 2 is fixedly connected to the middle of the lower part of the laying frame 1. The drive motor 2 is a large geared motor used to drive the hydraulic cylinders 3 to rotate. The length of the cylinder of the hydraulic cylinder 3 is greater than half the width of the laying frame 1 so that the output end of the hydraulic cylinder 3 can always be kept outside the laying frame 1. A U-shaped connecting plate 7 is fixedly connected to one side of the output end of the two hydraulic cylinders 3. A roll 11 containing the waterproof membrane is rotatably connected to one side of the connecting plate 7.

[0039] The connecting plate 7 is fixedly connected to two fixed boxes 28 on both sides of the drum 11. A fourth slide rod 39 is fixedly connected to each of the two fixed boxes 28. A connecting block 38 is slidably connected to each of the two fixed boxes 28. The two connecting blocks 38 slide on the fourth slide rod 39. A fourth spring 40 is fixedly connected between the two connecting blocks 38 and the fixed box 28. The fourth spring 40 is sleeved on the fourth slide rod 39. One end of the fourth spring 40 is fixedly connected to the connecting block 38, and the other end of the fourth spring 40 is fixedly connected to the side of the fixed box 28 away from the connecting block 38. A rotating column 29 for transmission is rotatably connected to one side of each of the two connecting blocks 38. A rolling wheel 31 is fixedly connected to the side of each of the two rotating columns 29 away from the connecting block 38.

[0040] Two rotating columns 29 are each fixedly connected to a rotating block 32 near the connecting block 38. Two connecting blocks 38 are each fixedly connected to a connecting frame 34 near the rotating block 32. Two connecting frames 34 are each fixedly connected to a third slide rod 36 near the rotating block 32. One end of each third slide rod 36 is fixedly connected to a trigger button 37. The button 37 is a miniature automatic reset button. The wire connecting the button 37 is a spring wire, which passes through the inside of the third slide rod 36, runs along one side of the connecting frame 34 to the connecting block 38, and then from the connecting block... 38 is connected to the wiring box on one side of the hydraulic cylinder 3 along the fixed box 28 and the connecting plate 7, then connected to the drive motor 2 along the hydraulic cylinder 3, and then along the laying frame 1 to the control panel on one side of the laying frame 1. Both third slide rods 36 are slidably connected to arc-shaped sliders 33. The two sliders 33 are fixedly connected to the connecting frame 34 with third springs 35. The third springs 35 are sleeved on the third slide rods 36. One end of the third springs 35 is fixedly connected to the sliders 33, and the other end of the third springs 35 is fixedly connected to one side of the connecting frame 34.

[0041] When laying the waterproof membrane in the tunnel, the laying frame 1 is placed in the middle of the tunnel, and the waterproof membrane on the roller 11 is fixed to the side of the tunnel near the ground. The hydraulic cylinder 3 is adjusted to move the connecting plate 7 so that the rolling wheel 31 presses against the inner wall of the tunnel. The drive motor 2 is started so that the two hydraulic cylinders 3 rotate simultaneously with the connecting plate 7. The connecting plate 7 rotates the waterproof membrane on the roller 11 to lay the waterproof membrane on the inner wall of the tunnel. The rotation of the connecting plate 7 rotates the fixing box 28 and the connecting block 38, so that the rotating column 29 rotates together with the rolling wheel 31 in the tunnel. The rolling wheel 31 can also rotate the rotating column 29 by friction with the tunnel. The rolling wheel 31 is pressed by the tunnel and drives the rotating column 29 to move so that the connecting block 38 slides in the fixing box 28 and compresses the fourth spring 40 through the fourth slide rod 39. The fourth spring 40 is always kept in a compressed state so that the fourth spring 40 can always press against the inner wall of the tunnel and roll.

[0042] The rolling wheel 31 is fixed to the rotating column 29 by a nut, and the third spring 35 is always compressed. The rolling wheel 31 rotates, causing the rotating column 29 to rotate on the connecting block 38. After the rolling wheel 31 rolls once on the tunnel, the rotating block 32 will push the arc surface of the slider 33, causing the slider 33 to move on the third sliding rod 36 and compress the third spring 35, so that the slider 33 presses the button 37. At this time, the drum 11 stops moving, and the length of the waterproof membrane unfolded on the drum 11 is the circumference of the rolling wheel 31. The radius of rotation of the rolling wheel 31 must be greater than the radius of rotation of the drum 11 in order to measure the unfolded length of the waterproof membrane by the rotation of the rolling wheel 31.

[0043] By removing and replacing the rollers 31 with different circumference sizes using nuts, waterproof membranes of different lengths can be laid out segment by segment on the tunnel wall. This allows the waterproof membranes of different lengths to be laid out and welded to the tunnel wall segment by segment when laying them in tunnels of different sizes and arches. This prevents the waterproof membranes from being too long to be difficult to weld and fix to the tunnel wall, reduces wrinkles and insufficient fit between the waterproof membranes and the tunnel, and enables the automatic laying of waterproof membranes of the required fixed length segment by segment on the tunnel wall, thus better welding and fixing the waterproof membranes to the tunnel wall.

[0044] Reference Figure 3 , Figure 4The connecting plate 7 is fixedly connected to sliding boxes 8 on both sides of the drum 11. Each sliding box 8 has a first sliding rod 14 for limiting the movement. A scraper 9 is slidably connected between the two sliding boxes 8. The scraper 9 is slidably connected to the two first sliding rods 14. A first spring 10 is fixedly connected between the scraper 9 and the sliding box 8. The first spring 10 is sleeved on the first sliding rod 14. One end of the first spring 10 is fixedly connected to one side of the scraper 9, and the other end of the first spring 10 is fixedly connected to one side of the sliding box 8. Limiting cylinders 13 for limiting the scraper 9 are opened on both sides of the scraper 9. A limiting piece 12 is fixedly connected to one end of each of the two first sliding rods 14. Both limiting pieces 12 are slidably connected to the limiting cylinders 13.

[0045] When the connecting plate 7 rotates inside the tunnel, the sliding box 8 causes the blade 9 to rotate and flatten the inner wall of the tunnel, allowing the waterproof membrane to better fit the tunnel. The radius of rotation of the blade 9 must be greater than the radius of rotation of the drum 11 so that the blade 9 can reach the tunnel first and flatten it. The first spring 10 is always kept compressed. The blade 9 can slide inside the sliding box 8 and the first slide rod 14 compresses the first spring 10 to prevent the blade 9 from making hard contact with the tunnel and damaging the blade 9. The limiting plate 12 slides inside the limiting cylinder 13 to make the blade 9 slide at the upper limit of the first slide rod 14 to prevent the blade 9 from sliding out of the sliding box 8.

[0046] Reference Figure 1 Two cylinders 5 are fixedly connected to both sides below the laying frame 1. A pressing plate 6 is fixedly connected between the output ends of the two cylinders 5 on the same side. Multiple grooves are opened on one side of the pressing plate 6 to increase friction. The pressing plate 6 is used to fix the waterproof board to the inner wall of the tunnel.

[0047] By activating cylinder 5 to move pressing plate 6, the initial end of the waterproof membrane is pressed and fixed to the inner wall of the tunnel by the friction surface of pressing plate 6. Then the roll 11 can be moved to lay the waterproof membrane.

[0048] Reference Figure 3 Both ends of the drum 11 are rotatably connected to a fixing block 16. The fixing blocks 16 on both sides are used to slide with the U-shaped plates on both sides of the connecting plate 7. Both sides of the connecting plate 7 are threadedly connected to a fixing bolt 15 on one side of the fixing block 16. Both fixing bolts 15 can be threadedly connected to the fixing block 16.

[0049] By sliding the fixing block 16 into the U-shaped frame of the connecting plate 7, the roll 11 with the waterproof membrane is placed in the U-shaped frame of the connecting plate 7. Then, the fixing block 16 is fixed to the connecting plate 7 by the fixing bolt 15. The waterproof membrane can be fixed to the connecting plate 7 by the roll 11 for laying. After the waterproof membrane on the roll 11 is laid, the fixing bolt 15 is rotated out to release the fixing between the fixing block 16 and the connecting plate 7. The new waterproof membrane can then be replaced by replacing the roll 11.

[0050] The implementation principle of a tunnel waterproofing membrane laying device according to an embodiment of this application is as follows:

[0051] The waterproof membrane is fixed to one end inside the tunnel by pressing plate 6, and then the roll 11 is moved to lay the waterproof membrane inside the tunnel. The length of the unfolded waterproof membrane is controlled by the rolling wheel 31 rolling on the inner wall of the tunnel. The waterproof membrane is laid in sections inside the tunnel. The inner wall of the tunnel is leveled by scraper 9 so that the waterproof membrane can better fit the tunnel. Then, the roll 11 is fixed to the connecting plate 7 by fixing bolt 15, so that the equipment can replace the roll 11 to replace the waterproof membrane. The equipment can continuously lay waterproof membranes in the tunnel. The equipment can better lay waterproof membranes in tunnels of different sizes and types, and prevent the waterproof membrane from being difficult to weld and fix to the inner wall of the tunnel due to excessive unfolding. It also reduces the problems of wrinkles and large gaps caused by insufficient fit between the waterproof membrane and the tunnel.

[0052] Example 2

[0053] Reference Figure 3 , 7 A threaded block 22 is slidably connected to the connecting plate 7 on one side of the drum 11. A telescopic rod 23 is fixedly connected to the threaded block 22 on the side away from the drum 11. A second motor 24 for driving is fixedly connected to the output end of the telescopic rod 23. An ultrasonic welding gun 25 for welding is fixedly connected to the output end of the second motor 24 through a connecting frame. A threaded rod 21 is rotatably connected to the connecting plate 7 on the side away from the drum 11. The threaded rod 21 is threadedly connected to the threaded block 22. A second gear 20 is fixedly connected to the end of the threaded rod 21 near the threaded block 22. A first motor 18 is fixedly connected to the connecting plate 7 on the side near the second gear 20. A first gear 19 is fixedly connected to the output end of the first motor 18. The first gear 19 is meshed with the second gear 20. A limiting groove 30 is opened on the connecting plate 7 on one side of the threaded block 22. A limiting plate 27 is fixedly connected to the threaded block 22 on one side. The limiting plate 27 is slidably connected to the limiting groove 30.

[0054] By starting the first motor 18, the first gear 19 rotates, causing the second gear 20 to rotate, which in turn rotates the threaded rod 21. The rotation of the threaded rod 21 causes the threaded block 22 to slide on the connecting plate 7 along with the telescopic rod 23. The movement of the telescopic rod 23 moves the second motor 24 and the ultrasonic welding gun 25, thus moving the ultrasonic welding gun 25 to weld and fix the waterproof membrane inside the tunnel. Starting the second motor 24 again allows the angle of the ultrasonic welding gun 25 to be adjusted so that it can always be at a 45-degree angle to weld and fix the waterproof membrane inside the tunnel. The ultrasonic welding gun 25 rotates with the connecting plate 7 inside the tunnel to weld the waterproof membrane, and the rotation radius of the ultrasonic welding gun 25 is smaller than the radius of the waterproof membrane laid by the roll 11, allowing the ultrasonic welding gun 25 to weld the waterproof membrane better. The sliding of the limiting plate 27 in the limiting groove 30 limits the sliding of the threaded block 22 on the connecting plate 7, preventing the threaded block 22 from slipping off the connecting plate 7, and allowing the threaded block 22 to slide normally.

[0055] Reference Figure 2 , Figure 7 The connecting plate 7 is fixedly connected to one side of the limiting groove 30 with a connecting shell 4 for protecting the line. A take-up box 26 for protecting the line is slidably arranged inside the connecting shell 4. One end of the take-up box 26 is fixedly connected to one side of the limiting plate 27, and the other end of the take-up box 26 is fixedly connected to the side of the connecting shell 4 away from the first motor 18.

[0056] The take-up box 26 is a nylon tank chain cable. It is used to connect the spring wire of the ultrasonic welding gun 25 along the body of the second motor 24 and the spring wire of the second motor 24. Then, it goes along the telescopic rod 23, passes through the threaded block 22 and is connected to the line of the telescopic rod 23. The line is then connected to the cable box on the side of the hydraulic cylinder 3 through the connecting plate 7 along the take-up box 26. The line of the ultrasonic welding gun 25, the second motor 24 and the telescopic rod 23 is connected to the control panel on the side of the laying frame 1 for control through the laying frame 1. The take-up box 26 collects and protects the line and pipe of the telescopic rod 23, the second motor 24 and the ultrasonic welding gun 25, so that the line and pipe can be connected to the equipment through the take-up box 26. The connecting shell 4 protects the take-up box 26 and the line and pipe inside the take-up box 26.

[0057] The transmission structure and other components in this application require precise design to avoid unstable operation of the equipment due to excessive friction or poor sliding.

[0058] The implementation principle of a tunnel waterproofing membrane laying device according to an embodiment of this application is as follows:

[0059] The waterproof membrane is welded and fixed in the tunnel by moving the ultrasonic welding gun 25 on the connecting plate 7, and the angle of the ultrasonic welding gun 25 is adjusted by the second motor 24 so that the ultrasonic welding gun 25 can perform welding better. The connecting shell 4 and the cable take-up box 26 protect the lines and pipes required for welding by the ultrasonic welding gun 25, ensuring that the welding work is carried out normally during the laying of the waterproof membrane.

[0060] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
