[0023] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example 1

[0025] Combined with appendix Figure 1-4 A tunnel lining device for water conservancy projects includes a lining trolley 1, which is used to move inside the tunnel and move the user to the working position. The lining trolley 1 consists of a support frame and a template. The template is installed on the support frame and contacts the tunnel. An operating platform 2 is fixedly installed at both the front and rear ends of the support frame of the lining trolley 1. A screw 3 is rotatably installed on one side of the bottom of the operating platform 2, and a sliding rod 5 is fixedly installed on the other side of the bottom of the operating platform 2. The surface of the screw 3 is threaded with a screw sleeve 4. The screw 3 drives the screw sleeve 4 to move up and down on the screw 3 by rotation. A sliding sleeve 6 is slidably fitted on the sliding rod 5. A lifting platform 7 is fixedly connected between the screw sleeve 4 and the sliding sleeve 6 on the same side. The lifting platform 7 transports the user to or from the operating platform 2 by moving up and down.

[0026] The lifting platform 7 is equipped with a first protective baffle 8, and the operating platform 2 is also equipped with a second protective baffle 88. The first protective baffle 8 and the second protective baffle 88 surround the lifting platform 7 and the operating platform 2 respectively, forming a protective frame that surrounds the lifting platform 7 and the operating platform 2. The protective frame is used to protect the user and prevent accidental falls when working on the lifting platform 7 and the operating platform 2.

[0027] The protective frame consisting of the first protective baffle 8 has a reserved notch. The first protective baffle 8 located on the side of the reserved notch on the lifting platform 7 has a hinge. A protective door 9 is installed on the hinge. Each protective door 9 is equipped with a locking component. The protective door 9 is part of the complete protective frame consisting of the first protective baffle 8. The protective door 9 can be opened to facilitate the user to enter the lifting platform 7. The locking component provides locking and opening functions for the protective door 9.

[0028] The locking assembly includes a groove 11 on the protective door 9, with a slider 12 slidably fitted inside the groove 11. Connecting plates 13 are fixedly connected to both sides of the slider 12. Multiple insert rods 14 are fixedly connected to the surface of any one of the connecting plates 13. A mounting block 15 is provided on the side of the protective baffle 8 corresponding to the insert rods 14. Multiple slots 23 matching the insert rods 14 are formed on the surface of the mounting block 15. The insert rods 14 are inserted into the slots 23, thus locking the protective door 9. A spring 16 is fixedly connected between the slider 12 and the inner wall of the groove 11 on the protective door 9, providing elasticity to maintain the state of the insert rods 14 inserted into the slots 23. When the user needs to open the protective door 9, the slider 12 is slid in the opposite direction, causing the slider 12 to disengage from the slots 23 carrying the insert rods 14. At this time, the protective door 9 can be opened via a hinge, facilitating the user's entry and exit from the lifting platform 7.

[0029] A protective plate 10 is slidably installed inside the protective frame composed of the second protective baffle 88 on the operating table 2. The protective frame composed of the second protective baffle 88 on the operating table 2 has a reserved slot 17 at the corresponding position of the protective door 9. The protective plate 10 is slidably installed in the position of the slot 17. A lead screw 18 is rotatably connected to one side of the second protective baffle 88 on any side of the slot 17. A threaded groove matching the lead screw 18 is opened on the protective plate 10. The protective plate 10 is sleeved on the lead screw 18 through the threaded groove.

[0030] On the other side of the second protective baffle 88 where the lead screw 18 of the slot 17 is located, a limiting rod 19 is fixedly connected. The protective plate 10 has a limiting groove that matches the limiting rod 19. The protective plate 10 is slidably sleeved on the outside of the limiting rod 19 through the limiting groove.

[0031] By rotating the lead screw 18, the protective plate 10 slides to the second protective baffle 88 on the side and overlaps with the second protective baffle 88. Rotating the lead screw 18 in the direction of rotation causes the protective plate 10 to slide out of the second protective baffle 88 again, occupying the position of the empty slot 17.

[0032] A rotating rod 20 is rotatably connected to the inner top wall of the second protective baffle 88 where the empty slot 17 is located. A first bevel gear 21 is fixedly connected to the bottom end of the rotating rod 20. A second bevel gear 22 is fixedly sleeved on the surface of the lead screw 18. The first bevel gear 21 and the second bevel gear 22 mesh with each other. The top end of the rotating rod 20 extends to the top of the protective baffle 8 and is fixedly connected to a rotating handle. By rotating the handle, the user can easily control the sliding of the protective plate 10 and adjust the position of the protective plate 10.

[0033] A drive motor 24 is fixedly installed at the lower end of the lining trolley 1. The output end of the drive motor 24 is fixedly connected to the screw 3. The drive motor 24 drives the screw 3 to rotate, thereby moving the lifting platform 7 up and down.

[0034] In use, the user moves the connecting plate 13 to disengage the insertion rod 14 from the slot 23, opening the outer protective door 9. The user can then enter the lifting platform 7. After closing the protective door 9, the spring 16 forces the insertion rod 14 into the slot 23 to lock the outer protective door 9. Then, the drive motor 24 rotates, causing the screw 3 to rotate, thus raising the lifting platform 7. Once it reaches the height of the operating platform 2, the inner protective door 9 opens inward. The rotating rod 20 then rotates, causing the first bevel gear 21 and the second bevel gear 22 to rotate, thus causing the protective plate 10 to retract into the empty slot 17. The user can then enter the operating platform 2. This convenient and quick device allows the user to quickly ascend to the top of the lining trolley without the need for time-consuming and laborious climbing. It also facilitates the lifting of tools and materials without the need for manual handling, making it convenient and fast.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
