Description

Technical Field

[0001] This utility model relates to the technical field of lining trolleys, and in particular to a hydraulic walking lining trolley traveling device. Background Technology

[0002] Lining trolleys are specialized equipment used for secondary lining concrete pouring in tunnel construction. Through modular design, they enable standardized and mechanized construction of tunnel structures and are key equipment in modern tunnel engineering. Due to the long length of tunnels, lining trolleys need to move during construction. Therefore, a hydraulic walking lining trolley traveling device is particularly needed.

[0003] However, most existing hydraulic walking lining trolleys cannot quickly adjust their walking direction and cannot quickly adapt to different tunnel construction tasks.

[0004] To solve the above problem, after searching, publication number CN 218265935 was found. U's patent discloses a walking steel formwork trolley with a corbel structure. The patent states that "during tunnel construction, in order to fix and support the inner wall of the tunnel with concrete, a steel formwork trolley is needed for secondary lining construction within the tunnel. Typical steel formwork trolleys usually only have an arched template at the top, and then concrete is poured through the pump interface 4 and push-pull slide plate 5 on the arched template. Most tunnel lining construction steel formwork trolleys use rail-mounted steel formwork trolleys, but these are difficult to fix and move in tunnels with a maximum slope of 11%, and are highly dangerous." This utility model proposes a walking steel formwork trolley with a corbel structure. It is a hydraulically driven walking steel formwork trolley with ground-supporting diagonal braces and triangular diagonal braces for support, ensuring the stability of the steel formwork trolley during concrete pouring and guaranteeing the safety of the steel formwork trolley during movement in tunnels with a maximum slope of 11% and during concrete pouring.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a hydraulic walking lining trolley traveling device, including a base plate 1, a support leg 2 fixedly installed on one side surface of the base plate 1, a connecting shell 3 fixedly installed on both sides surface of the support leg 2, a vertical hydraulic cylinder 4 fixedly installed inside the connecting shell 3, a first push-pull rod 5 fixedly connected to the output end of the vertical hydraulic cylinder 4, a lifting column 6 fixedly connected to the other end of the first push-pull rod 5, a connecting column 9 bearing connected to one end of the lifting column 6, a first connecting ring 10 fixedly installed on the outer wall of the connecting column 9, a connecting block 11 fixedly connected to the other end of the connecting column 9, and a slider 12 fixedly installed on the lower surface of the connecting block 11. A support plate 13 is connected to the outer wall of block 12. A groove 14 is formed on one side surface of the support plate 13. A horizontal hydraulic cylinder 15 is fixedly installed on one side surface of the support plate 13. A second push-pull rod 16 is fixedly connected to the output end of the horizontal hydraulic cylinder 15. A mounting plate 17 is fixedly installed on one side surface of connecting block 11. A motor 18 is fixedly installed on the lower surface of the mounting plate 17. A connecting shaft 19 is fixedly connected to the output end of the motor 18. A second connecting ring 20 is fixedly installed on the outer wall of the connecting shaft 19. A transmission belt 21 is sleeved on the outer wall of the second connecting ring 20. The transmission belt 21 passes through the base plate 1, support leg 2, connecting shell 3, vertical hydraulic cylinder 4, first push-pull rod 5, and lifting mechanism. The arrangement of column 6, connecting column 9, first connecting ring 10, connecting block 11, slider 12, support plate 13, slide groove 14, horizontal hydraulic cylinder 15, second push-pull rod 16, mounting plate 17, motor 18, connecting shaft 19, second connecting ring 20, and transmission belt 21 allows the motor 18 to rotate the second connecting ring 20 via the connecting shaft 19 during trolley movement. Under the action of the transmission belt 21, the first connecting ring 10 will rotate synchronously with the second connecting ring 20. This allows the connecting column 9 to rotate the connecting block 11 and support plate 13 to a suitable angle, enabling rapid adjustment of the trolley's movement direction to adapt to different construction tunnels. When the trolley is in motion, the horizontal hydraulic cylinder 15 lowers the lifting column 6, and the support plate 13 rests on the ground. At this time, the horizontal hydraulic cylinder 15 causes the second push-pull rod 16 to push the connecting block 11. With the assistance of the slider 12, the connecting block 11 can move horizontally on the support plate 13, and the trolley moves forward a certain distance. At this time, the vertical hydraulic cylinder 4 raises the lifting column 6, the support plate 13 leaves the ground, and the support leg 2 rests on the ground. Then the horizontal hydraulic cylinder 15 is activated again. Under the action of the second push-pull rod 16, the horizontal hydraulic cylinder 15 moves towards the connecting block 11, and then the vertical hydraulic cylinder 4 pushes the lifting column 6 again. By repeating this process, the trolley can move automatically.

[0022] Furthermore, the lifting column 6 forms a lifting structure with the vertical hydraulic cylinder 4 via the first push-pull rod 5. With the first push-pull rod 5 in place, the first push-pull rod 5 can move the lifting column 6 up and down, thereby moving the trolley.

[0023] Furthermore, the two ends of the second push-pull rod 16 are fixedly connected to the horizontal hydraulic cylinder 15 and the connecting block 11, respectively. With the setting of the second push-pull rod 16, the second push-pull rod 16 can push the connecting block 11 and pull the horizontal hydraulic cylinder 15 to realize the movement of the trolley.

[0024] Furthermore, the slider 12 forms a sliding structure with the support plate 13 through the slide groove 14. With the slider 12 and the slide groove 14, when the second push rod 16 pushes the connecting block 11, the slider 12 will slide in the slide groove 14. The slider 12 can assist and limit the movement of the connecting block 11.

[0025] Furthermore, the two ends of the transmission belt 21 are respectively fitted onto the outer walls of the first connecting ring 10 and the second connecting ring 20. The second connecting ring 20 forms a rotating structure with the mounting plate 17 through the connecting shaft 19. Through the setting of the transmission belt 21, the transmission belt 21 can make the first connecting ring 10 and the second connecting ring 20 rotate synchronously, thereby adjusting the moving direction of the trolley.

[0026] Furthermore, limit blocks 7 are fixedly installed on both sides of the lifting column 6, and limit grooves 8 are opened on both sides of the inner wall of the connecting shell 3. With the setting of the lifting column 6, the lifting column 6 can lift and lower the connecting column 9. When the lifting column 6 descends to the support plate 13, it can be supported on the ground.

[0027] Furthermore, the limiting block 7 forms a sliding structure with the connecting shell 3 through the limiting groove 8. With the setting of the limiting block 7 and the limiting groove 8, the limiting block 7 can assist and limit the lifting movement of the lifting column 6 when it slides in the limiting groove 8.

[0028] Working principle: During the movement of the trolley, the motor 18 can drive the second connecting ring 20 to rotate through the connecting shaft 19. Under the action of the transmission belt 21, the first connecting ring 10 will rotate synchronously with the second connecting ring 20. In this way, the connecting column 9 will drive the connecting block 11 and the support plate 13 to rotate to a suitable angle. When the trolley moves, the horizontal hydraulic cylinder 15 lowers the lifting column 6, and the support plate 13 will be supported on the ground. At this time, the horizontal hydraulic cylinder 15 causes the second push rod 16 to push the connecting block 11. With the assistance of the slider 12, the connecting block 11 can move horizontally on the support plate 13, and the trolley moves forward a certain distance. At this time, the vertical hydraulic cylinder 4 raises the lifting column 6, the support plate 13 leaves the ground, and the support leg 2 is supported on the ground. Then the horizontal hydraulic cylinder 15 starts again. Under the action of the second push rod 16, the horizontal hydraulic cylinder 15 moves towards the connecting block 11, and then the vertical hydraulic cylinder 4 pushes the lifting column 6 again. By repeating this process, the trolley can move automatically.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
