Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel construction technology, specifically to an intelligent automatic positioning and laying device for waterproof membrane based on image reference. Background Technology
[0002] Tunnel construction refers to the process of excavating a tunnel and installing auxiliary equipment. During tunnel construction, a waterproof membrane needs to be laid on top of the tunnel to prevent water from seeping into the tunnel from the top.
[0003] Existing patent (CN217783534U) discloses a tunnel waterproof membrane laying machine, belonging to the field of tunnel construction technology. It primarily addresses the cumbersome manual installation and poor correction methods used when laying waterproof membranes on the tunnel roof, which easily lead to skew errors and require secondary compaction. The machine includes a base, a frame in the middle of the base, a drive motor in the middle of the frame, a first bevel gear at the bottom of the drive motor, annular slide rails at both ends of the base, and a swinging device in the middle of the frame. The top of the swinging device passes through the annular slide rails. The swinging device lays the waterproof membrane onto the curved roof by swinging. Compaction components are located at both ends of the frame below the swinging device. These compaction components extend and press against the surface of the laid waterproof membrane as the swinging device swings, compacting the membrane.
[0004] The device features a swing mechanism that allows the waterproof membrane to be attached to the tunnel ceiling by swinging left and right, providing better control over its application and installation. During installation, the overlapping sections must meet construction specifications. Due to potential displacement during installation, the membrane's position needs to be adjusted in real time. The membrane is positioned using heat-fused connections with lining pins. Since there are numerous lining pins, traditional methods of finding and fusion-connecting them one by one are costly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] See Figures 1-6 A smart automatic positioning and laying device for waterproof membrane based on image reference includes symmetrically arranged support rods 1, which are connected to a trolley via telescopic units. The end faces of the symmetrical support rods 1 are fixedly connected via connecting frames 2. A bearing shaft 3 for placing rolled waterproof membrane is fixedly installed on one side inside the connecting frame 2. A baffle 4 is provided at the other end of the connecting frame 2, which is inserted into the connecting frame 2 and the bearing shaft 3. The rolled waterproof membrane is placed on the outer surface of the bearing shaft 3. The waterproof membrane is laid by rotating the support rods 1. Telescopic collars 5 are fixedly installed on the sides of the connecting frame 2 and the baffle 4 that are close to each other. A push ring 6 is fixedly installed on the free end of the telescopic collar 5. Both the telescopic collar 5 and the push ring 6 are sleeved on the outer surface of the bearing shaft 3. During the laying of the waterproof membrane, the position of the waterproof membrane can be changed by the push ring 6 through the opposite movement of the telescopic collar 5, so that the overlap of the waterproof membrane meets the specifications. The top of the surface connecting frame 2 extends towards the hinge end of the support rod 1 with a protrusion 7. The end of the protrusion 7 is equipped with a camera 8 for taking pictures. The camera 8 is used to photograph and identify the position of the laid waterproof membrane and the pre-embedded lining nails. Since the color of the waterproof membrane is much different from the color of the tunnel wall, and the lining nails are generally in a conspicuous color such as red, it is relatively easy to identify the laid waterproof membrane and the pre-embedded lining nails after imaging. By identifying the position of the waterproof membrane, the position of the waterproof membrane can be changed by adjusting the telescopic collar 5.
[0024] A guide rail 9 is fixedly installed on the inner side of the connecting frame 2 below the bearing shaft 3. A bearing groove 10 parallel to the guide rail 9 is opened on one side of the guide rail 9. A rack plate 11 is embedded inside the bearing groove 10. A connecting sleeve 12 is slidably connected to the outer surface of the guide rail 9. A motor 13 is fixedly installed on the surface of the connecting sleeve 12. A gear 14 that meshes with the rack plate 11 is fixedly installed at the output end of the motor 13. A telescopic sleeve 15 is fixedly installed at the free end of the connecting sleeve 12. A hot melt pressure head 16 is fixedly installed at the free end of the telescopic sleeve 15. Based on the identified position of the shim pin, when the guide rail 9 swings to be flush with the shim pin, the rotating gear 14 drives the connecting sleeve 12 to move. In conjunction with the extension of the telescopic sleeve 15, the hot melt pressure head 16 can be changed to hot melt the waterproof plate and the shim pin to complete the fixation.
[0025] An internal transverse limiting rod 17 is fixedly installed inside the connecting frame 2. Through holes 18 are opened on both sides of the connecting frame 2. A tension limiting rod 19 is slidably connected inside the through holes 18. Nuts 20 are threadedly connected to the tension limiting rods 19 on both sides of the connecting frame 2. This setting can prevent the connecting frame 2 from deforming.
[0026] The outer surface of the bearing shaft 3 is provided with a threaded hole 21, and a threaded post 22 is connected to the inside of the threaded hole 21. An elastic telescopic sleeve 23 is fixedly installed at the top of the threaded post 22. The fixed end surface of the elastic telescopic sleeve 23 is provided with a positioning hole 24 for rotation. The free end of the elastic telescopic sleeve 23 is provided with a rolling unit 25. This arrangement makes it easy to insert the rolled waterproof board into the outer surface of the bearing shaft 3. During the insertion process, the elastic telescopic sleeve 23 is squeezed.
[0027] The rolling unit 25 is a rotating wheel 251. The plane of the rotating wheel 251 is kept tangent to the end face of the bearing shaft 3. The reason for setting the rotating wheel 251 and making it tangent to the end face of the bearing shaft 3 is to avoid excessive idling of the rolled waterproof board.
[0028] A sliding sleeve 26 is fitted onto the outer surface of the protrusion 7. A threaded shaft 27 is threadedly connected to the middle of the protrusion 7. The threaded shaft 27 is rotatably connected to the sliding sleeve 26. The adjusting end of the threaded shaft 27 extends to the outside of the sliding sleeve 26. A rotating platform 28 with its bottom end accommodating the adjustment of the threaded shaft 27 is fixedly installed on the end face of the sliding sleeve 26. A rotatable rotating seat 29 is fastened to the outer surface of the rotating platform 28 by a nut 20. The camera 8 is fixedly installed on the surface of the rotating seat 29. With this arrangement, the position of the camera 8 can be adjusted so that the camera 8 can capture the whole picture inside.
[0029] In use, the rolled waterproof membrane is placed on the outer surface of the bearing shaft 3. The waterproof membrane is laid by rotating the support rod 1. The camera 8 is used to capture and identify the position of the laid waterproof membrane and the pre-embedded padding nails. During the laying of the waterproof membrane, the position of the waterproof membrane can be changed by the push ring 6 through the opposite movement of the telescopic collar 5, so that the overlap of the waterproof membrane meets the specifications. When the guide rail 9 swings to be flush with the padding nail, the connecting sleeve 12 is moved by the rotating gear 14, and the extension of the telescopic sleeve 15 can change the position of the hot melt pressure head 16, so that the hot melt pressure head 16 hot melts the waterproof membrane and the padding nail to complete the fixation. It should be noted that the padding nail includes a hot melt washer, a steel washer and a steel nail. The waterproof membrane is fixed to the hot melt washer in the padding nail by hot melting.
[0030] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
