[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1.

This ensures both the overall rigid support of the track body and the flexible adjustment capability of the track body. At the same time, the setting of dual electric push rods can ensure the parallel lifting and lowering of the support plate through synchronous drive to adapt to different installation heights, and can also independently control the adjustment of the tilt angle on one side, perfectly matching the changes in the tunnel ground slope, ensuring the stability of the track body and adapting to the requirements of different terrains.

By utilizing the cooperation of the sliding rod and the rotating square tube, as well as the tilt angle design of the first and second limiting blocks, combined with the first spring reset mechanism, a unidirectional rigid support is formed, effectively preventing the connecting block from retracting, enhancing the lateral support strength, improving the installation stability of the track body, and preventing it from loosening or displacing. Especially during the operation of the carrying trolley, it significantly improves the dynamic load bearing capacity of the track body and enhances the safety and durability of the track body for long-term use.

[0017] 3. In this invention, by setting up installation components, the positioning plate fits against both ends of the track body and adjusts the curvature arrangement to ensure precise matching between the track and the tunnel curvature, improving the track installation accuracy and fit. The movable screw and connecting slide rod work together to drive the second screw seat and connecting box to move, realizing the linkage adjustment between the rotating shaft and the connecting plate. At the same time, the constraint of the limiting rod on the fixed ring is quickly released by the transverse connecting rod, which facilitates flexible adjustment of the angle of the two connecting plates to adapt to the different curvature requirements of the two track bodies, enhancing the adaptability of the assembly. Meanwhile, the cooperation of the first insertion ring, the second insertion ring and the insertion rod enables rapid disassembly and assembly between the two track bodies, thereby reducing the time and labor intensity of track body assembly and improving construction efficiency.

[0026] The specific implementation method is as follows: By setting the installation component 7, the positioning plate 701 fits against both ends of the track body 2 and the curvature arrangement is adjusted to ensure that the track and tunnel curvature are accurately matched, thereby improving the track installation accuracy and fit. The movable screw 709 and the connecting slide rod 707 work together to drive the second screw seat 702 and the connecting box 706 to move, thereby realizing the linkage adjustment of the rotating shaft 711 and the connecting plate 704. At the same time, the transverse connecting rod 708 quickly releases the constraint of the limiting rod 710 on the fixed ring 714, which facilitates the flexible adjustment of the angles of the two connecting plates 704 to adapt to the different curvature requirements of the two track bodies 2 and enhances the adaptability of the assembly. Meanwhile, the cooperation of the first insertion ring 705, the second insertion ring and the insertion rod 703 enables the rapid disassembly and assembly between the two track bodies 2, thereby reducing the assembly time and labor intensity of the track bodies 2 and improving the construction efficiency.

[0027] Working principle: During use, workers lay the main track 2 inside the tunnel. First, they lay the support base 3 inside the tunnel and adjust the height and angle of the support plate 505 according to the slope of the tunnel floor. Then, they activate the electric push rods 506. The two electric push rods 506 can move synchronously with the same stroke or move independently. When the two electric push rods 506 operate synchronously, they drive the sliding block 502 to move synchronously. The sliding block 502 then drives the connecting rod 504 to move synchronously, allowing the connecting rod 504 to move the support plate 505 in a parallel posture. The vertical lifting and lowering is used to adjust the overall height of the support plate 505. When the electric push rod 506 operates alone, the electric push rod 506 drives one of the sliding blocks 502 to move. The sliding block 502 drives the connecting rod 504 to move. The connecting rod 504 drives the support plate 505 to move, causing the support plate 505 to deflect around the hinge seat at the other end, thereby changing the relative angle of the support plate 505 to adapt to the slope of the tunnel surface. Afterward, the workers place the track body 2 on the support plate 505 and fix the track body 2 to the support plate 505 by installing bolts 503. Next, the worker places the connecting block 403 on the side of the track body 2, ensuring that one side of the connecting block 403 is flush with one side of the track body 2. Then, the worker rotates the rotating rod, which drives the first bevel gear 407 to rotate. The first bevel gear 407 drives the second bevel gear 408 to rotate, and the second bevel gear 408 drives the moving screw 709 to rotate. The moving screw 709 then moves the first screw seat 414, which in turn moves the friction block 404, allowing the friction block 404 to rub against and limit its movement against the inner wall of the track, thus completing the connection with the track body 2. During this process, the connecting block... The connecting block 403 drives the sliding rod 402 to move. The sliding rod 402 moves inside the rotating square tube 401. The sliding rod 402 drives the first limiting block 405 to move. During the movement of the first limiting block 405, the second limiting block 412 moves through its own tilt angle. After the first limiting block 405 moves away, the second limiting block 412 resets under the action of the first spring 413 and provides unidirectional support to the first limiting block 405, thereby achieving unidirectional rigid support for the sliding rod 402. This allows the connecting block 403 to provide lateral support to both sides of the track body 2, ensuring the stability of the installation of the track body 2. Next, the workers attached the two ends of the two track bodies 2 together and adjusted the arrangement of the track bodies 2 according to the curvature of the tunnel. Then, the workers rotated the movable screw 709, which, in conjunction with the connecting slide rod 707, moved the second screw seat 702. The second screw seat 702 then moved the connecting box 706, which in turn moved the rotating shaft 711 and the connecting plate 704. This caused the two opposing connecting plates 704 to move the first insertion ring 705 and the second insertion ring. After that, the workers... The operator pulls the transverse connecting rod 708, which moves the limiting rod 710, thereby releasing the limitation on the fixed ring 714. The operator adjusts the angle between the two connecting plates 704 according to the curvature between the two track bodies 2, so that the first insertion ring 705 and the second insertion ring fit together and are coaxial. Then, the operator inserts the insertion rod 703 into the first insertion ring 705 and the second insertion ring, thereby completing the installation of the two track bodies 2.
