[0023] 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.
[0024] This utility model discloses a concrete lining device for water diversion tunnel construction.
[0025] This utility model provides, for example Figure 1-3 The concrete lining device for water diversion tunnel construction shown includes a concrete box 1. Two mounting plates 2 are fixedly connected to the upper surface of the concrete box 1. A rotating shaft 3 is rotatably connected to one side of each mounting plate 2. A first pipe body 4 is fixedly connected between the two rotating shafts 3. A second pipe body 5 is slidably arranged inside the first pipe body 4. A concrete nozzle 6 is fixedly connected to one end of the second pipe body 5. An adjustment mechanism is provided between the first pipe body 4 and the second pipe body 5. The second pipe body 5 moves through the adjustment mechanism. A driving mechanism is provided on the upper surface of the concrete box 1. One of the rotating shafts 3 rotates through the driving mechanism.
[0026] Move the concrete box 1 to the middle of the tunnel, then adjust the position of the second pipe 5 so that the overall length of the first pipe 4 and the second pipe 5 is slightly less than the radius of the tunnel. Then rotate the first pipe 4 so that the concrete nozzle 6 can spray concrete evenly on the inner wall of the tunnel. That is, by adjusting the position of the second pipe 5, the device can be used for tunnels of different sizes.
[0027] In order for the second tube 5 to be movable, such as Figure 1-2 As shown, the adjustment mechanism includes two support plates 7, a first lead screw 8, a sleeve 9, and a first motor 10. The two support plates 7 are respectively fixedly connected to one side of the first tube 4 and the second tube 5. The first lead screw 8 is rotatably connected to the upper surface of one of the support plates 7. The sleeve 9 is threaded onto the rod wall of the first lead screw 8. The upper end of the sleeve 9 is fixedly connected to the lower surface of the other support plate 7. The first motor 10 is fixedly connected to the lower surface of the corresponding support plate 7. The lower end of the first lead screw 8 passes through the upper surface of the corresponding support plate 7 and is fixedly connected to the output end of the first motor 10.
[0028] Start the first motor 10 to make the first lead screw 8 rotate, which in turn drives the sleeve 9 to move upward, thereby allowing the second tube 5 to move.
[0029] To make the first tube 4 rotate, such as Figure 1 and Figure 3 As shown, the drive mechanism includes a sector gear 11, two fixed plates 12, a second lead screw 13, a slider 14, a rack 15, and a second motor 18. The two fixed plates 12 are symmetrically fixed to the upper surface of the concrete box 1. The second lead screw 13 is rotatably connected between the two fixed plates 12. The slider 14 is threaded onto the rod wall of the second lead screw 13. The sector gear 11 is fixedly sleeved onto the rod wall at one end of the corresponding rotating shaft 3. The rack 15 is fixedly connected to the upper surface of the slider 14 and meshes with the sector gear 11. The second motor 18 is fixedly connected to one side of the corresponding fixed plate 12. One end of the second lead screw 13 passes through one side of the corresponding fixed plate 12 and is fixedly connected to the output end of the second motor 18.
[0030] Start the second motor 18 to make the second lead screw 13 rotate. Here, the second lead screw 13 is a reciprocating lead screw. Then, the slider 14 can drive the rack 15 to move back and forth, and then the sector gear 11 can rotate back and forth, so that the first tube 4 can rotate back and forth.
[0031] In order for the concrete to be sprayed out, such as Figure 2 As shown, a pump body 16 is fixedly connected inside the concrete box 1. The output end of the pump body 16 is fixedly connected to the third pipe body 17. The upper end of the third pipe body 17 penetrates the lower surface inside the concrete box 1 and is fixedly connected to the lower end of the second pipe body 5.
[0032] Start the pump body 16, and then the concrete can flow into the third pipe body 17 and be sprayed out through the concrete nozzle 6.
[0033] To facilitate the rotation of the first tube 4, such as Figure 2 As shown, the third tube 17 is a flexible tube.
[0034] Because the third tube 17 is a flexible tube, it will not hinder the rotation of the first tube 4.
[0035] To prevent slider 14 from rotating, such as Figure 1 and Figure 3 As shown, the lower surface of slider 14 is in contact with the upper surface of concrete box 1.
[0036] Because the slider 4 is in contact with the upper surface of the concrete box 1, it can play a limiting role and prevent the slider 14 from rotating with the second lead screw 13.
[0037] 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.
