Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] like Figure 1-4 As shown, a tunnel secondary lining inspection auxiliary platform includes a base 1. Four rectangularly distributed first mounting rods 2 are fixedly connected to the top of the base 1. A first lifting mechanism is installed inside each first mounting rod 2.

A vertically arranged second lifting groove 8 is opened inside each second mounting plate 7. A second lifting mechanism is installed inside each second lifting groove 8. A horizontally arranged second lifting platform 17 is fixedly connected to both second lifting mechanisms. A horizontally arranged first sliding groove 18 is opened inside the second lifting platform 17. A first slider 22 is slidably arranged within the first sliding groove 18. An operating table 24 is fixedly connected to the top of the second lifting platform 17 after the top of the first slider 22 extends out of the second lifting platform 17. The operating table 24 is slidably connected to the top of the second lifting platform 17.

[0022] Furthermore, a third threaded rod 20 is rotatably connected to the inside of the first sliding groove 18 via a bearing. The first slider 22 is threaded onto the outside of the third threaded rod 20. A third servo motor 21 is fixedly installed inside the first sliding groove 18, and the output end of the third servo motor 21 is fixedly connected to the third threaded rod 20. Through the cooperation of the third threaded rod 20, the third servo motor 21, and the first slider 22, the operating platform 24 can be moved laterally, thereby bringing the operating platform 24 closer to the inner wall of the tunnel, thus facilitating the inspection of the arch area by the staff.

[0023] Furthermore, the second lifting platform 17 has two T-shaped second sliding grooves 19 inside, located on both sides of the first sliding groove 18. A T-shaped second slider 23 is slidably installed inside each of the second sliding grooves 19, with the top of the second slider 23 fixedly connected to the bottom of the operating platform 24. Through the cooperation of the second sliding grooves 19 and the second slider 23, the operating platform 24 can be limited, ensuring stability during operation.

[0024] Furthermore, the first mounting rod 2 is provided with a first lifting groove 3 inside, and the first lifting mechanism includes a first threaded rod 4 rotatably connected to the first lifting groove 3 through a bearing. A first lifting block 5 is threadedly sleeved on the outer side of the first threaded rod 4. The first lifting block 5 is fixedly connected to the first lifting platform 6. The base 1 is provided with a synchronous lifting device POWERBASE. The synchronous lifting device POWERBASE is connected and cooperates with four first threaded rods 4 to drive the first threaded rods 4 to rotate, thereby enabling the first lifting block to drive the first lifting platform 6 to rise and fall smoothly, ensuring the normal operation of the first lifting mechanism.

[0025] Furthermore, the second lifting mechanism includes a second threaded rod 9 rotatably connected to the inside of the second lifting groove 8 via a bearing. A second lifting block 10 is threaded onto the outer side of the second threaded rod 9. The second lifting platform 17 is fixedly connected between the two second lifting blocks 10. A first transmission groove 11 is respectively opened inside the first lifting platform 6 located below the two second threaded rods 9. A first worm gear column 12 is rotatably connected to the inside of the first transmission groove 11 via a bearing. The upper end of the first worm gear column 12 extends into the inside of the second lifting groove 8 and is fixedly connected to the second threaded rod 9. The bottom worm gear 12 engages with the first worm post 13. The interior of the first lifting platform 6 has an installation groove. Inside the installation groove, two corresponding first bevel gear posts 14 are rotatably connected via bearings. One end of each first bevel gear post 14 extends into the interior of the adjacent first transmission groove 11 and is fixedly connected to the first worm post 13. The two bevel gears of the two first bevel gear posts 14 are arranged adjacently and mesh with a second bevel gear post 15. A second servo motor 16 is also fixedly installed inside the first lifting platform 6, and its output end is fixedly connected to the second bevel gear post 15. Through the mutual cooperation of the first worm post 12, the first worm post 13, the first bevel gear post 14, the second bevel gear post 15, and the second servo motor 16, the two second threaded rods 9 can be driven to rotate, thereby ensuring the normal operation of the second lifting mechanism. The second lifting mechanism can drive the second lifting platform 17 to rise and fall, thereby further adjusting the height of the operating platform 24, facilitating the inspection of the arched top by the operator.

[0026] Furthermore, a guardrail 25 is provided on the top of the operating platform 24, and two corresponding guide grooves are opened inside the second mounting plate 7. Guide rods are fixedly connected inside the guide grooves, and four guide blocks are fixedly connected to the outside of the second lifting platform 17. The guide rods pass through the guide blocks and are slidably connected to them.

[0027] Furthermore, the base 1 is equipped with an electric drive wheel at its bottom, and an electric H-shaped support leg is also provided inside the base 1.

[0028] Working Process and Principle: The tunnel lining inspection auxiliary platform is operated by personnel via a remote control device. The electric drive wheels (model MDL230-1.3) at the bottom of base 1 move the platform to the inspection position. Then, the control device activates the electric H-shaped outriggers (model ARS0161) inside base 1, extending them to contact the ground and providing external support for the platform, improving its stability. Personnel then enter through the entrance on the outside of guardrail 25 and adjust the platform according to inspection requirements. When inspecting the arch section, the control device activates the synchronous lift (model POWER) inside base 1. BASE drives the four first threaded rods 4 to operate, which in turn drives the four first lifting blocks 5 to rise and fall, thereby driving the first lifting platform 6 and the second mounting plate 7 to rise and fall. This adjusts the height of the second lifting platform 17 and the operating platform 24. Then, the control device starts the third servo motor 21 to drive the third threaded rod 20 to rotate, which in turn drives the first slider 22 to slide inside the first sliding groove 18. This causes the operating platform 24 to move laterally, while simultaneously driving the second slider 23 to slide inside the second sliding groove 19, bringing the operating platform 24 closer to the tunnel wall. This facilitates the inspection of the arch waist and the arch crown by the staff. The device uses a step lifter (model POWERBASE) to drive four first threaded rods 4, which in turn drive four first lifting blocks 5 to rise and fall. This, in turn, drives the first lifting platform 6 and the second mounting plate 7 to rise and fall. Then, the control device starts the second servo motor 16 to drive the second bevel gear column 15 and two first bevel gear columns 14, which in turn drive the two first worm gear columns 13 and the first worm wheel column 12. This drives the two second threaded rods 9 to rotate, which in turn drives the two second lifting blocks 10 to rise and fall. This, in turn, raises the second lifting platform 17 and the operating platform 24 again, making it easier for staff to inspect the arch.
