Description

Technical Field

[0001] This invention relates to a tunnel waterproof membrane laying machine, belonging to the technical field of waterproof membrane laying machines. Background Technology

[0002] Tunnel construction refers to the process of excavating tunnels and installing auxiliary equipment. During tunnel construction, it is necessary to lay waterproof membranes on the top of the tunnel. The laying of waterproof membranes is the core and key to tunnel waterproofing technology. The construction quality of the waterproof membranes is crucial to the overall waterproofing effect of the tunnel. Usually, a tunnel waterproof membrane laying machine is needed to lay the waterproof membranes on the inner wall of the tunnel. However, existing waterproof membrane laying machines require high precision in the installation of the tracks. In order to fit the waterproof membranes, the laying trolley needs to be frequently hoisted and moved in coordination with the tracks. Therefore, it has the disadvantages of cumbersome operation and low laying efficiency.

[0003] For example, Chinese invention patent CN109281690A discloses a tunnel waterproof membrane laying machine, which includes a platform and a tunnel waterproof membrane laying trolley on the platform. The laying trolley includes a frame, a waterproof membrane base, a waterproof membrane slide, a waterproof membrane roll, a circumferential traveling mechanism, a height adjustment and longitudinal swing adjustment mechanism, and a longitudinal adjustment mechanism. Since the laying machine travels on the track laid inside the tunnel, the track is first laid according to the distance between the left and right rollers installed at the bottom of the laying machine. In order to facilitate the laying of the waterproof membrane, the laying machine needs to be in the middle position inside the tunnel. During the track laying process, the distance between the tracks needs to be accurately measured, which reduces the laying efficiency.

[0004] Therefore, improvements are urgently needed. Summary of the Invention

[0005] In order to overcome the shortcomings of existing waterproof membrane laying machines, such as high installation accuracy requirements and low laying efficiency, this invention designs a tunnel waterproof membrane laying machine, which improves track laying efficiency, has good applicability, and high safety.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tunnel waterproof membrane laying machine includes a platform, a track mechanism fixed at the top of the platform and arranged along the arc-shaped cross-section of the tunnel, a laying mechanism for laying waterproof membrane slidably installed on the track mechanism, and a moving mechanism fixed at the bottom of the platform. The moving mechanism includes several moving components for moving the platform and an adjustment mechanism for driving the moving components to move along the tunnel cross-section.

[0008] Furthermore, the adjustment mechanism includes a fixed base fixed to the bottom of the platform, a first slide groove is provided in the fixed base, an adjustment screw is rotatably provided in the first slide groove, one end of the adjustment screw passes through the fixed base and is connected to a first motor, a first slider is also slidably provided in the first slide groove, the adjustment screw is threaded through the first slider, and the bottom end of the first slider slides through the fixed base and is fixedly connected to the moving component.

[0009] Furthermore, the moving component includes a drive box with an open bottom, and a plurality of telescopic cylinders are provided inside the drive box. The fixed end of each telescopic cylinder is fixedly connected to the inner wall of the top of the drive box, and the telescopic end of each telescopic cylinder is rotatably connected to a moving wheel. The moving wheels are connected to each other through a linkage mechanism.

[0010] Furthermore, the laying mechanism includes a laying trolley that is slidably mounted on a track mechanism. A laying system is installed on the top of the laying trolley. The laying system includes a support base. A fourth electric cylinder is fixed to the top of the support base. A pair of fixing ears are installed on the top of the fourth electric cylinder. A waterproof membrane roll is rotatably connected between the two fixing ears. A third motor for driving the waterproof membrane roll to rotate is fixed on one of the fixing ears.

[0011] Furthermore, a fixing block is installed at the top of the fourth electric cylinder, and a second sliding groove is provided inside the fixing block. A sliding plate is slidably installed inside the second sliding groove, and a first shock-absorbing spring is fixed to the bottom end of the second sliding groove. A connecting plate is installed at the top of the sliding plate, and the top of the connecting plate slides through the fixing block and connects to the fixing lug.

[0012] Furthermore, a base plate is fixedly installed between the fourth electric cylinder and the fixed block. Several pairs of fifth electric cylinders are hinged to the base plate and symmetrically arranged on both sides of the fixed block. A connecting seat is hinged to the free end of the fifth electric cylinder. One end of the connecting seat is hinged to the fixed block, and the other end is rotatably connected to a pressure roller.

[0013] Furthermore, the free end of the fifth electric cylinder is hinged with a second slider, and a sliding cavity is provided on the side of the connecting seat near the fifth electric cylinder along the length setting direction. The second slider is slidably locked in the sliding cavity, and the two ends of the second slider are respectively fixedly installed with the two ends inside the sliding cavity with second shock-absorbing springs.

[0014] Furthermore, several limiting rods are provided between the support base and the base plate, and each limiting rod slides through the support base.

[0015] Furthermore, several transverse movement mechanisms are installed on both sides of the platform, with a worktable mounted on each mechanism and a fourth motor mounted on each mechanism. The fourth motor drives the transverse movement mechanism to move the worktable transversely along the tunnel cross-section.

[0016] Furthermore, a third electric cylinder is installed at the top inner side of each fixed base. The telescopic end of the third electric cylinder moves downward through the fixed base and is fixedly connected to a support plate.

[0017] Compared with the prior art, the present invention has the following features and beneficial effects:

[0018] 1. This invention, by setting a track mechanism along the arc-shaped cross-section of the tunnel, allows the laying mechanism to slide along the track mechanism to lay waterproof membranes at various locations within the tunnel, greatly improving the applicability of the device. Through the setting of the adjustment mechanism, the position of the moving component can be adjusted, allowing the moving component to connect with the laid ground track. Different locations can also be adjusted to accommodate two ground tracks with different spacings, facilitating the rapid installation of two parallel ground tracks. This improves the connection efficiency between the device and the ground track, avoiding repeated measurement and installation operations of the ground track position, thereby improving the laying efficiency of the waterproof membrane.

[0019] 2. This invention controls the up-and-down movement of the moving wheels via a telescopic cylinder, allowing the wheels to adapt to uneven road surfaces, improving the stability of the platform during operation, and ensuring the platform is always in the optimal laying position, thus facilitating the laying of the waterproof membrane. Simultaneously, the telescopic cylinder controls the extension and retraction of the moving wheels; when the platform needs to be moved, the ground-mounted moving wheels can be extended to contact the ground for movement, and when docking with the ground track, the track-mounted moving wheels can be extended to dock with the ground track, facilitating the platform's movement on the ground or track, improving the device's applicability, avoiding the need for hoisting, and enhancing the safety of installing the device on two ground tracks.

[0020] 3. This invention uses a fourth electric cylinder to push the base plate to move away from the curved track, so that the waterproof membrane roll is pressed tightly against the inner wall of the tunnel. As the amount of waterproof membrane on the roll decreases, the pressure between the waterproof membrane roll and the inner wall of the tunnel is kept within a certain range, which facilitates the laying of the waterproof membrane on the inner wall of the tunnel and improves the laying effect. At the same time, the fifth electric cylinder pushes the connecting seat to rotate. The rotation of the connecting plate causes the pressure roller to contact the waterproof membrane laid on the inner wall of the tunnel, so that the waterproof membrane can be effectively pressed.

[0028] The present invention will now be described in more detail with reference to the embodiments.

[0029] like Figures 1 to 6 As shown, a tunnel waterproof membrane laying machine includes a platform 1. A track mechanism is fixed at the top of the platform 1 and arranged along the arc-shaped cross-section of the tunnel. A laying mechanism for laying waterproof membrane is slidably installed on the track mechanism. A moving mechanism is fixed at the bottom of the platform 1. The moving mechanism includes several moving components for moving the platform 1 and an adjustment mechanism for driving the moving components to move along the tunnel cross-section.

[0030] As can be seen from the above description, the beneficial effects of the present invention are as follows: by setting a track mechanism along the arc-shaped cross-section of the tunnel, the laying mechanism can slide along the track mechanism to lay waterproof membranes at various locations in the tunnel, greatly improving the applicability of the device. By setting an adjustment mechanism, the position of the moving component can be adjusted, allowing the moving component to connect with the laid ground track. Different positions can also be adjusted to accommodate two ground tracks with different spacings, facilitating the rapid installation of two parallel ground tracks, improving the connection efficiency between the device and the ground track, and avoiding repeated measurement and installation operations of the ground track position, thereby improving the laying efficiency of the waterproof membrane.

[0031] Furthermore, the adjustment mechanism includes a fixed base 4 fixed to the bottom of the platform 1. A first slide groove is provided in the fixed base 4. An adjustment screw 6 is rotatably provided in the first slide groove. One end of the adjustment screw 6 passes through the fixed base 4 and is connected to a first motor 7. A first slider 5 is also slidably provided in the first slide groove. The adjustment screw 6 is threaded through the first slider 5, and the bottom end of the first slider 5 slides through the fixed base 4 and is fixedly connected to the moving component.

[0032] As can be seen from the above description, the rotation of the adjusting screw 6 driven by the first motor 7 causes the first slider 5 to move laterally. The translation of the first slider 5 can drive the moving component to move, thereby realizing the position adjustment of the moving component and facilitating the accurate docking of the moving component with the ground track.

[0033] Furthermore, the moving component includes a drive box 8 with an open bottom. Several telescopic cylinders are installed inside the drive box 8. The fixed end of each telescopic cylinder is fixedly connected to the inner wall of the top of the drive box 8. Each telescopic cylinder has a moving wheel rotatably connected to its telescopic end. The moving wheels are connected to each other through a linkage mechanism.

[0034] As described above, the telescopic cylinder controls the up-and-down movement of the moving wheels, allowing them to adapt to uneven road surfaces. This improves the stability of the platform 1 during operation and ensures that the platform 1 is always in the optimal laying position, facilitating the laying of the waterproof membrane. Furthermore, the telescopic cylinder controls the extension and retraction of the moving wheels. When the platform 1 needs to be moved, the ground moving wheels can be extended to contact the ground for movement. When docking with the ground track, the track docking moving wheels can be extended to dock with the ground track, facilitating the platform 1's movement on the ground or track. This improves the applicability of the device, avoids the need for hoisting, and enhances the safety of installing the device on two ground tracks.

[0035] Furthermore, the laying mechanism includes a laying trolley 3 that is slidably mounted on a track mechanism. A laying system is mounted on the top of the laying trolley 3. The laying system includes a support base 25. A fourth electric cylinder 26 is fixed to the top of the support base 25. A pair of fixing ears 33 are mounted on the top of the fourth electric cylinder 26. A waterproof membrane roll 34 is rotatably connected between the two fixing ears 33. A third motor 35 for driving the waterproof membrane roll 34 to rotate is fixed on one of the fixing ears 33.

[0036] As can be seen from the above description, the support base 25 serves to fix the installation. By driving the fourth electric cylinder 26 to move the fixing ear 33, the waterproof membrane roll 34 can be pressed tightly against the inner wall of the tunnel, thereby laying the waterproof membrane. The fourth electric cylinder 26 has high transmission efficiency, good reliability and stable operation, making it suitable for promotion and use.

[0037] Furthermore, a fixing block 29 is installed at the top of the fourth electric cylinder 26. A second slide groove is provided inside the fixing block 29. A slide plate 30 is slidably installed in the second slide groove. A first shock-absorbing spring 31 is fixed to the bottom end of the slide groove and the inner end of the second slide groove. A connecting plate 32 is installed at the top of the slide plate 30. The top of the connecting plate 32 slides through the fixing block 29 and is connected to the fixing ear 33.

[0038] As can be seen from the above description, when the waterproof membrane roll 34 is attached to the inner wall of the tunnel, the first damping spring 31 is compressed, so that the first damping spring 31 always maintains the thrust against the slide plate 30, thereby ensuring that the waterproof membrane roll 34 can always be attached to the inner wall of the tunnel when the fourth electric cylinder 26 extends to the corresponding position. At the same time, the first damping spring 31 can also play a certain role in shock absorption, effectively ensuring the stability of the waterproof membrane during the laying process.

[0039] Furthermore, a base plate 27 is fixedly installed between the fourth electric cylinder 26 and the fixed block 29. Several pairs of fifth electric cylinders 42 are hinged on the base plate 27 and symmetrically arranged on both sides of the fixed block 29. A connecting seat 36 is hinged to the free end of the fifth electric cylinder 42. One end of the connecting seat 36 is hinged to the fixed block 29, and the other end is rotatably connected to the pressure roller 37.

[0040] As can be seen from the above description, the fifth electric cylinder 42 pushes the connecting seat 36 to rotate around the hinge point. The rotation of the connecting seat 36 causes the pressure roller 37 to contact the waterproof membrane laid on the inner side wall of the tunnel, thus pressing the waterproof membrane to ensure the laying effect of the waterproof membrane and prevent the waterproof membrane from falling off. Pressure rollers 37 are set on both sides of the fixing block 29 to ensure uniform pressing.

[0041] Furthermore, the free end of the fifth electric cylinder 42 is hinged with a second slider 38, and the connecting seat 36 has a sliding cavity 50 on the side near the fifth electric cylinder 42 along the length setting direction. The second slider 38 is slidably locked in the sliding cavity 50, and the two ends of the second slider 38 are respectively fixedly installed with the two ends inside the sliding cavity 50 with second shock-absorbing springs 39.

[0042] As can be seen from the above description, when the fifth electric cylinder 42 pushes the connecting seat 36 to rotate around the hinge point, the second slider 38 slides in the sliding cavity 50, which in turn compresses or stretches the second damping springs 39 at both ends of the second slider 38, and achieves shock absorption under the elastic force of the second damping springs 39.

[0043] Furthermore, a number of limiting rods 48 are provided between the support base 25 and the base plate 27, and each limiting rod 48 is slidably installed through the support base 25.

[0044] As can be seen from the above description, the limiting rod 48 plays a limiting role, preventing the base plate 27 from causing the fourth electric cylinder 26 to sway left and right, and thus protecting the fourth electric cylinder 26.

[0045] Furthermore, several transverse movement mechanisms are installed on both sides of the platform 1. A worktable 47 is installed on the transverse movement mechanism, and a fourth motor 46 is installed on the transverse movement mechanism. The fourth motor 46 drives the transverse movement mechanism to move the worktable 47 transversely along the tunnel cross-section.

[0046] As can be seen from the above description, the worktable 47 is slid left and right by the transverse mechanism, which makes it easy to store the worktable 47 inside the frame 1, facilitates the transportation of this device, and allows the worktable 47 to extend to the outside of the frame 1 so that people can stand on the worktable 47 to work.

[0047] Furthermore, a third electric cylinder 23 is installed on the top inner side of each fixed base 4. The telescopic end of the third electric cylinder 23 moves downward through the fixed base 4 and is fixedly connected to a support plate 24.

[0048] As can be seen from the above description, the support plate 24 is moved by the third electric cylinder 23, so that the support plate 24 can support the ground, ensuring the stability of the support of the platform 1 during operation. Furthermore, the support plate 24 can be retracted when the platform 1 is moved, which facilitates transportation.

[0049] Example 1

[0050] In this embodiment, a tunnel waterproofing membrane laying machine is applied to a long straight tunnel with a pre-laid track.

[0051] like Figures 1 to 3 As shown, a tunnel waterproof membrane laying machine includes a platform 1, which is welded together from several longitudinal beams and several transverse beams. A track mechanism is fixed at the top of the platform 1 along the arc-shaped cross-section of the tunnel. A laying mechanism for laying waterproof membranes is slidably installed on the track mechanism. A moving mechanism is fixed at the bottom of the platform 1. The moving mechanism includes two moving components and an adjustment mechanism for driving the moving components to move along the tunnel cross-section. The adjustment mechanism is set one-to-one with the two moving components.

[0052] In this embodiment, the track mechanism includes a pair of arc-shaped tracks 2 fixed to the top of the platform 1. The two arc-shaped tracks 2 are arranged along the length of the tunnel. The laying mechanism is slidably installed between the two arc-shaped tracks 2. The arc-shaped tracks 2 serve as a guide, making it convenient for the laying mechanism to slide to different positions and proceed with the laying and installation of the waterproof membrane.

[0053] Furthermore, the adjustment mechanism includes a fixed base 4 fixed to the bottom of the platform 1. A first slide groove is provided in the fixed base 4. An adjustment screw 6 is rotatably provided in the first slide groove. One end of the adjustment screw 6 passes through the fixed base 4 and is connected to a first motor 7. A first slider 5 is also slidably provided in the first slide groove. The adjustment screw 6 is threaded through the first slider 5, and the bottom end of the first slider 5 slides through the fixed base 4 and is fixedly connected to the moving component.

[0054] In this embodiment, a first distance sensor is provided at the ends of the two fixed seats 4 that are far apart from each other. The first distance sensor is used to detect the distance between the fixed seat 4 and the inner wall of the tunnel. The fixed seat 4 and the first motor 7 are both connected to a host computer. The host computer generates a control signal based on the distance information of the first distance sensor. The host computer controls the start, stop or forward and reverse rotation of the first motor 7 through the control signal of the host computer, thereby driving the first slider 5 to slide along the first slide groove, so that the platform 1 moves laterally relative to the tunnel, which facilitates the accurate movement of the paving machine to the middle position of the tunnel.

[0055] Furthermore, two transverse movement mechanisms are installed on both sides of the platform 1. A worktable 47 is installed on the transverse movement mechanism, and a fourth motor 46 is installed on the transverse movement mechanism. The fourth motor 46 drives the transverse movement mechanism to move the worktable 47 transversely along the tunnel cross section.

[0056] In this embodiment, the transverse mechanism includes a fixed plate 43 fixed on the frame 1. A horizontal third slide groove is provided in the fixed plate 43. A first screw 45 is rotatably installed in the third slide groove. One end of the first screw 45 rotates through the fixed plate 43 and is connected to the fourth motor 46 for transmission. A third slider 44 is also slidably installed in the third slide groove. The first screw 45 is threaded through the third slider 44, and the top of the third slider 44 slides out of the third slide groove and is fixedly connected to the worktable 47. A second distance sensor is provided at the end of the worktable 47 near the inner wall of the tunnel. The fourth motor 46 and the second distance sensor are both electrically connected to the host computer. The fourth motor 46 drives the first screw 45 to rotate, which in turn drives the third slider 44 to slide along the length of the third slide groove, thereby driving the worktable 47 to be retracted or opened. The host computer generates a control signal based on the distance information of the second distance sensor. The host computer controls the start, stop, forward and reverse rotation of the fourth motor 46 through the control signal, realizing intelligent control with high safety, convenient and fast control, and high efficiency.

[0057] Furthermore, a third electric cylinder 23 is installed on the top inner side of each fixed base 4. The telescopic end of the third electric cylinder 23 moves downward through the fixed base 4 and is fixedly connected to a support plate 24.

[0058] In this embodiment, a plurality of fixing teeth 49 are fixed at the bottom end of the support plate 24. The setting of fixing teeth 49 increases the friction between the support plate 24 and the ground, thereby improving the support stability of the support plate 24 for the device.

[0059] Example 2

[0060] In this embodiment, a tunnel waterproofing membrane laying machine is also applied to a long straight tunnel with a pre-laid track.

[0061] A tunnel waterproofing membrane laying machine, based on the above-described embodiment one, further defines the overall mechanical connection relationship of the laying mechanism as follows:

[0062] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the laying mechanism includes a laying trolley 3 that is slidably mounted on a track mechanism. A laying system is installed on the top of the laying trolley 3. The laying system includes a support base 25. Two fourth electric cylinders 26 are fixed on the top of the support base 25. The two fourth electric cylinders 26 are arranged back and forth along the tunnel length direction. A pair of fixing ears 33 are installed on the top of the fourth electric cylinders 26. A waterproof membrane roll 34 is rotatably connected between the two fixing ears 33. A third motor 35 for driving the waterproof membrane roll 34 to rotate is fixed on one of the fixing ears 33.

[0063] Furthermore, a fixing block 29 is installed at the top of each of the two fourth electric cylinders 26. A second slide groove is provided inside the fixing block 29. A slide plate 30 is slidably installed inside the second slide groove. A first shock-absorbing spring 31 is fixed to the bottom end of the slide plate 30 and the inner end of the second slide groove. A connecting plate 32 is installed at the top of the slide plate 30. The top of the connecting plate 32 slides through the fixing block 29 and is connected to the fixing ear 33.

[0064] Furthermore, a base plate 27 is fixedly installed between the fourth electric cylinder 26 and the fixed block 29, and a first pressure sensor 28 is provided between each fourth electric cylinder 26 and the base plate 27. Two pairs of fifth electric cylinders 42 are hinged on the base plate 27 and symmetrically arranged on both sides of the fixed block 29. A connecting rod 40 is fixedly connected to the free end of the fifth electric cylinder 42. A second slider 38 is hinged to the free end of the connecting rod 40. A second pressure sensor 41 is provided between the connecting rod 40 and the fifth electric cylinder 42. A connecting seat 36 is provided at the free end of the second slider 38. One end of the connecting seat 36 is hinged to the fixed block 29, and the other end is rotatably connected to a pressure roller 37. A sliding cavity 50 is opened along the length direction on the side of the connecting seat 36 near the fifth electric cylinder 42. The second slider 38 is slidably locked in the sliding cavity 50, and a second shock-absorbing spring 39 is fixedly installed at both ends of the second slider 38 and the two ends inside the sliding cavity 50, respectively.

[0065] Specifically, each pressure sensor and each electric cylinder is electrically connected to the host computer.

[0066] Furthermore, a number of limiting rods 48 are provided between the support base 25 and the base plate 27, and each limiting rod 48 is slidably installed through the support base 25.

[0067] In this embodiment, the fourth electric cylinder 26 pushes the base plate 27 to move away from the curved track 2, so that the waterproof membrane roll 34 is pressed tightly against the inner wall of the tunnel. The first pressure sensor 28 senses the pressure between the waterproof membrane roll 34 and the inner wall of the tunnel, and the second pressure sensor 41 senses the pressure between the pressure roller 37 and the inner wall of the tunnel. The host computer receives the pressure signal and adjusts the position of the waterproof membrane roll 34 and the connecting seat 36 according to the change of the curvature inside the tunnel by controlling the fourth electric cylinder 26 and the fifth electric cylinder 42. At the same time, as the waterproof membrane on the waterproof membrane roll 34 decreases, the pressure between the waterproof membrane roll 34 and the inner wall of the tunnel can always be kept within the corresponding range, which facilitates the laying of the waterproof membrane on the inner wall of the tunnel and improves the laying effect. At the same time, the fifth electric cylinder 42 pushes the connecting seat 36 to rotate, and the connecting plate 32 rotates so that the pressure roller 37 contacts the waterproof membrane laid on the inner wall of the tunnel and presses the waterproof membrane tightly.

[0068] Example 3

[0069] In this embodiment, a tunnel waterproofing membrane laying machine is also applied to a long straight tunnel with a pre-laid track.

[0070] A tunnel waterproofing membrane laying machine, based on the above-described embodiment one, further defines the overall mechanical connection relationship of the moving components as follows:

[0071] like Figure 1 , Figure 2 and Figure 6As shown, the moving component further includes a drive box 8 with an open bottom. Several telescopic cylinders are installed inside the drive box 8. The fixed end of each telescopic cylinder is fixedly connected to the inner wall of the top of the drive box 8. Each telescopic cylinder has a movable wheel rotatably connected to its telescopic end. The movable wheels are connected to each other through a linkage mechanism.

[0072] Furthermore, the telescopic cylinder includes several second electric cylinders 16 and several first electric cylinders 12. The telescopic end of the first electric cylinder 12 is fixed with a first adjusting seat 9, and the telescopic end of the second electric cylinder 16 is fixed with a second adjusting seat 13. Both the first adjusting seat 9 and the second adjusting seat 13 are slidably connected to the inner wall of the drive box 8. The bottom end of the first adjusting seat 9 is rotatably connected with a track roller 10, and the bottom end of the second adjusting seat 13 is rotatably connected with a ground roller 14.

[0073] Furthermore, the linkage mechanism includes a second motor 22, a sprocket assembly, and a chain 21 that is driven by the sprocket assembly. The sprocket assembly includes a first sprocket 11 that is driven by each track roller 10 and a second sprocket 15 that is driven by each ground roller 14. The second motor 22 is fixed on the outer wall of the drive box 8 for driving the sprocket assembly to rotate.

[0074] Furthermore, the sprocket assembly also includes several third sprockets 18 and several fourth sprockets 20 rotatably disposed on the inner wall of the drive housing 8. Several sliding clamping cavities 51 are provided on the inner wall of the drive housing 8. Adjusting blocks 17 are slidably disposed in the sliding clamping cavities 51. A first compression spring 19 is connected between the bottom end of the adjusting block 17 and the bottom wall of the sliding clamping cavity 51. Each third sprocket 18 is rotatably connected to each adjusting block 17 in a corresponding manner.

[0075] In this embodiment, the drive box 8 is equipped with a second electric cylinder 16 and two first electric cylinders 12. The two first electric cylinders 12 are symmetrically arranged on both sides of the second electric cylinder 16. There are two fourth sprockets 20, which are respectively arranged on the side of the two first electric cylinders 12 that are far apart from each other. There are two third sprockets 18, which are respectively arranged between the two first electric cylinders 12 and the second electric cylinder 16. The sprockets are connected by a chain 21. The first compression spring 19 pushes the adjusting block 17 and the third sprocket 18 to move upward, so that the chain 21 is always in a taut state, ensuring the stability of the chain 21 transmission and thus ensuring the smooth progress of the laying work.

[0076] The working principle of this invention is as follows: During use, the platform 1 can be moved to different positions inside the tunnel to lay the waterproof membrane by the ground rollers 14 rolling on the ground. Additionally, the track rollers 10 allow for quick docking with the ground tracks, facilitating movement and improving laying efficiency. Specifically, two tracks are first laid parallel inside the tunnel. After the tracks are laid, the platform 1 is moved above the laid tracks by the ground rollers 14 rolling on the ground. Then, the third electric cylinder 23 pushes two support plates 24 to support the platform 1, moving the track rollers 10 and ground rollers 14 to the upper side of the tracks. Then, the first motor 7 drives the drive box 8 to move, moving the track rollers 10 directly above the two tracks. Then, the first electric cylinder 12 pushes the first adjusting seat 9 and track rollers 10 downwards, while the second electric cylinder 16 pulls the second adjusting seat 13 and ground rollers 14 upwards, moving the track rollers 10 below the ground rollers 14. Finally, the third electric cylinder 16... Electric cylinder 23 pulls the support plate 24 upward, and the platform 1 moves downward relative to it until the support plate 24 separates from the ground, causing the track rollers 10 to press on the track and support the platform 1. Then, multiple fourth electric cylinders 26 push the bottom plate 27 to move away from the curved track 2, so that the waterproof membrane roll 34 is pressed against the inner wall of the tunnel. The third motor 35 drives the waterproof membrane roll 34 to rotate, causing the waterproof membrane to rotate down. The fifth electric cylinder 42 pushes the connecting seat 36 to rotate, and the connecting plate 32 rotates, causing the pressure roller 37 to contact the laying... The waterproof membrane is pressed firmly against the inner wall of the tunnel. At the same time, the laying trolley 3 drives the laying system to travel on the surface of two tracks, so that the waterproof membrane is laid on the inner wall of the tunnel. After the laying is completed, the second motor 22 drives the two fourth sprockets 20, the two first sprockets 11, the second sprockets 15, the two third sprockets 18, the chain 21, the two track rollers 10 and the ground rollers 14 to rotate, so that the track rollers 10 roll on the ground, so that the laying machine moves on the track and moves the laying machine to the next position where the waterproof membrane needs to be laid.
