[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model discloses a mechanical device for rapid installation and disassembly of tunnel lining templates.

[0023] Reference Figure 1-3A mechanical device for rapid installation and disassembly of tunnel lining formwork includes a base plate 1 and a top plate 5. The top plate 5 is disposed on the upper side of the base plate 1. First sliding grooves are formed at both ends of the base plate 1, and a first sliding plate 2 is slidably disposed inside the first sliding grooves. Second sliding grooves are formed at both ends of the top plate 5, and L-shaped plates 3 are slidably disposed inside the second sliding grooves. A vertical groove is formed at the bottom end of the L-shaped plate 3, and a vertical plate 4 is slidably disposed inside the vertical groove. The lower end of the vertical plate 4 is fixedly connected to the first sliding plate 2. A first hydraulic cylinder 6 is fixedly disposed on the upper surface of the top plate 5, and a second hydraulic cylinder 9 is fixedly disposed on the outer wall of the L-shaped plates 3. A horizontal plate 18 is disposed between the upper ends of the two L-shaped plates 3, and belts are provided on both sides of the horizontal plate 18. The first transmission mechanism for moving the L-shaped plate 3 relative to the top plate 5 includes a fixed plate 12 between the bottom plate 1 and the top plate 5. Vertical tubes 14 are fixedly installed on both sides of the upper surface of the bottom plate 1. Vertical rods 13 are slidably sleeved inside the vertical tubes 14. The upper end of the vertical rods 13 is fixedly connected to the fixed plate 12. A first lead screw 19 is rotatably installed between the fixed plate 12 and the top plate 5. A horizontal plate 18 is threadedly sleeved with the first lead screw 19. A through groove is opened in the middle of the fixed plate 12. A first motor 17 is fixedly installed on the upper inner wall of the through groove. The output end of the first motor 17 is fixedly connected to one end of the first lead screw 19. A second transmission mechanism for driving the L-shaped plate 3 to move longitudinally is provided on the lower side of the fixed plate 12.

[0024] Reference Figure 1-3 The first transmission mechanism includes a slider 21 and a push rod 23. A groove is formed on the inner side of the upper end of the L-shaped plate 3. A limit rod 22 is fixedly installed inside the groove. The slider 21 is movably sleeved on the wall of the limit rod 22. The push rod 23 is positioned between the slider 21 and the top plate 5. Both ends of the push rod 23 are rotatably connected to connecting blocks 24 via pins 25. The lower connecting block 24 is fixedly connected to the slider 21, and the upper connecting block 24 is fixedly connected to the top plate 5. A third sliding groove is formed at both ends of the horizontal plate 18. A sliding mechanism is slidably installed inside the third sliding groove. The second slide plate 20 has one end fixedly connected to the corresponding slider 21. The first motor 17 drives the first lead screw 19 to rotate, which causes the horizontal plate 18 to move longitudinally, thereby causing the horizontal plate 18 to push the slider 21 to move. This causes the push rod 23 to rotate towards the horizontal, thereby pushing the two L-shaped plates 3 to move horizontally relative to the top plate 5, thus realizing the adjustment of the width of the device. The cross-section of both the slider 21 and the groove is rectangular, and the inner wall of the groove abuts against the side wall of the slider 21, so that the slider 21 can slide stably in the groove.

[0025] Reference Figure 1-3The second transmission mechanism includes an internally threaded tube 15 and a second lead screw 16. The internally threaded tube 15 is fixedly installed on the upper surface of the top plate 5. The second lead screw 16 is threaded into the inside of the internally threaded tube 15. The upper end of the second lead screw 16 is rotatably connected to the fixed plate 12. A second motor 26 is fixedly installed on the lower side of the inside of the through groove. The output end of the second motor 26 is fixedly connected to one end of the second lead screw 16. The second motor 26 drives the second lead screw 16 to rotate, which enables the second lead screw 16 to move relative to the internally threaded tube 15, which cannot rotate. This enables the fixed plate 12 to move relative to the bottom plate 1, thereby driving the horizontal plate 18 to move longitudinally. This causes the horizontal plate 18 to drive the L-shaped plate 3 to move longitudinally, thus enabling the height of the device to be adjusted.

[0026] Reference Figure 1-3 The top of each of the two L-shaped plates 3 is fixedly provided with a first support tube 7, and the first support rod 8 is movably sleeved inside the first support tube 7, which can improve the working stability of the first hydraulic cylinder 6. The side wall of the L-shaped plate 3 and located on both sides of the second hydraulic cylinder 9 are fixedly provided with a second support tube 10, and the second support rod 11 is movably sleeved inside the second support tube 10, which can improve the working stability of the second hydraulic cylinder 9.

[0027] In this invention, during use, based on the tunnel cross-sectional dimensions, the second motor 26 is first activated to adjust the height of the fixed plate 12 to the target value. Then, the first motor 17 drives the first lead screw 19 to rotate, causing the horizontal plate 18 to move longitudinally along the lead screw, which in turn drives the second sliding plate 20 and the slider 21 to slide on the limiting rod 22. The push rod 23 pushes the L-shaped plate 3 horizontally along the second sliding groove of the top plate 5 via the shaft pin 25, thereby adjusting the spacing of the L-shaped plates 3. Subsequently, the first hydraulic cylinder 6 and the second hydraulic cylinder 9 extend to lift the template to the designed position and fix it, completing the rapid installation. Disassembly is performed in reverse, with each mechanism working together to achieve rapid template descent and retraction.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
