Description

Technical Field

[0001] This invention relates to the field of urban rail transit engineering technology, and more specifically to prefabricated assembly equipment used in urban rail transit engineering. Background Technology

[0002] Urban rail transit is a public transportation system that uses dedicated tracks for operation. It is a public transportation mode that transports passengers in the form of trains through dedicated, fully or partially enclosed track lines. Among them, subways have the highest passenger volume. In the construction of subways, there are two construction methods for the construction of stations and tunnels: one is the cast-in-place concrete construction method, and the other is the use of prefabricated components that are manufactured in factories and transported to the site for assembly. With the advent of high efficiency, the prefabricated component method has gradually become the mainstream. When assembling prefabricated components, rail transit engineering assembly equipment is required.

[0003] However, existing prefabricated assembly equipment used in urban rail transit projects mostly involves lifting prefabricated components piece by piece into the shaft using hoisting equipment, followed by on-site installation by workers. To prevent the pit from collapsing, multiple sets of transverse steel beams are installed inside the pit, making it easy for prefabricated components to collide with the steel beams during hoisting, potentially causing safety accidents. Furthermore, when installing on the tunnel sidewalls, workers need to frequently adjust the position of the prefabricated components to make them parallel to the tunnel sidewalls. Due to the large weight of the prefabricated components, the labor intensity for workers is high, making it difficult to promote and use.

[0004] To address this issue, this application provides prefabricated assembly equipment for urban rail transit engineering. Summary of the Invention

When installing on the sidewalls of the tunnel, workers need to frequently adjust the position of the prefabricated components, which makes the prefabricated components prone to collision with steel beams during hoisting, causing safety accidents, as well as the high labor intensity of workers and poor use effect.

[0011] A further improvement of the technical solution of the present invention is that: a traction connecting frame is fixedly installed at one end of the traction steel cable, a second hook is fixedly installed at the bottom of the traction connecting frame, a right-angle transmission reducer is fixedly installed at one end of the second motor, and the right-angle transmission reducer is fixedly installed inside the first sliding block.

[0012] A further improvement of the technical solution of the present invention is that: a second rotating wheel is fixedly installed inside the right-angle transmission reducer, the second rotating wheel is rotatably installed at the bottom of the movable bracket, a first lifting plate is fixedly installed at one end of the second hydraulic rod, and the second guide rail is arranged inside the first lifting plate.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows: 1. This invention provides a prefabricated assembly equipment for urban rail transit engineering. Under the combined action of a rectangular support plate, a first rotating wheel, and a first motor, a mobile device is formed by a transport component and the rectangular support plate. A track is laid in the tunnel, and the first motor in the transport component drives the mobile device to move on the track, transporting prefabricated components into the tunnel.

[0020] The present invention will be further described in detail below with reference to embodiments: like Figure 1-7As shown, the present invention provides a prefabricated assembly equipment for urban rail transit engineering, including a support component 1, a transport component 2, an installation component 3, and a lifting component 4. The support component 1 connects and installs the transport component 2, the installation component 3, and the lifting component 4. The transport component 2 enables the device to move. The installation component 3 and the lifting component 4 facilitate the installation of prefabricated components. At the same time, the transport component 2, the installation component 3, and the lifting component 4 can transport multiple prefabricated components simultaneously, improving the efficiency of subway construction.

[0021] like Figure 1 and Figure 5 As shown, the support assembly 1 includes a rectangular support plate 10, a first guide rail 13, and a second guide rail 14. The first guide rail 13 and the second guide rail 14 are both fixedly installed on the top of the rectangular support plate 10. The installation assembly 3 is installed through the first guide rail 13, and a portion of the lifting assembly 4 is installed through the second guide rail 14, allowing the installation assembly 3 and the lifting assembly 4 to move on it, which facilitates the subsequent installation of prefabricated components.

[0022] like Figure 5 As shown, a support column 11 is fixedly installed on the top of the rectangular support plate 10. The precast component is placed through the support column 11, and a certain distance is maintained between the precast component and the rectangular support plate 10, so as to facilitate the movement of the precast component by the installation component 3 and the lifting component 4.

[0023] like Figure 5 As shown, limit blocks 15 are fixedly installed at both ends of the first guide rail 13 and the second guide rail 14. The limit blocks 15 limit the maximum moving distance of the movable bracket 30 and the third hydraulic rod 42, preventing the movable bracket 30 and the third hydraulic rod 42 from detaching from the guide rail.

[0024] like Figure 3 and Figure 4 As shown, the transport component 2 is fixedly installed at the bottom of the support component 1. The transport component 2 includes a mounting frame 20, a first motor 23, a first rotating wheel 21, a first hydraulic rod 24, and a first hook 26. The first motor 23 is fixedly installed inside the mounting frame 20, and the first hydraulic rod 24 is fixedly installed on one side of the mounting frame 20. A connecting plate 25 is fixedly installed at one end of the first hydraulic rod 24, and the first hook 26 is fixedly installed at the bottom of the connecting plate 25. The two ends of the precast component are hooked by the first hook 26 at the bottom of the rectangular support plate 10, and then the first hydraulic rod 24 extends, driving the connecting plate 25 and the first hook 26 to move upward, lifting the precast component off the ground for transport. This device can also transport subway rails, sleepers, etc.

[0025] like Figure 2-4As shown, the mounting frame 20 is fixedly installed at the bottom of the rectangular support plate 10. The first rotating wheel 21 is located at the bottom of the mounting frame 20. A rotating shaft 27 is rotatably installed inside the mounting frame 20. The first rotating wheel 21 is fixedly installed outside the rotating shaft 27. A dual-output end reducer 22 is fixedly installed inside the mounting frame 20. One end of the first motor 23 is fixedly installed inside the dual-output end reducer 22. The rotating shaft 27 is fixedly installed inside the dual-output end reducer 22. The first motor 23 drives the first rotating wheel 21 to rotate through the dual-output end reducer 22, thus moving the device. The rectangular support plate 10, the first rotating wheel 21, and the first motor 23 together form a moving device, enabling the device to move on the track and transport the prefabricated components into the tunnel. Through the combined action of the rectangular support plate 10, the first rotating wheel 21, and the first motor 23, the installation of the prefabricated components can be carried out from inside the tunnel, reducing the probability of collision with the steel beams and preventing safety accidents.

[0026] like Figure 2 and Figure 6 As shown, the mounting assembly 3 is movably mounted on top of the support assembly 1. The mounting assembly 3 includes a movable bracket 30, a second motor 32, a third motor 35, and a winch 36. The winch 36 is fixedly mounted on one end of the third motor 35. A truss 31 is fixedly mounted on the top of the movable bracket 30. The third motor 35 is fixedly mounted on the bottom of the truss 31. The winch 36 is rotatably mounted on the bottom of the truss 31. The movable bracket 30 is located on top of the rectangular support plate 10. A traction cable 37 is movably connected to the outside of the winch 36. A traction connecting frame 38 is fixedly mounted on one end of the traction cable 37. A second hook 39 is fixedly mounted on the bottom of the traction connecting frame 38. The end of the precast component is hooked by the second hook 39. The third motor 35 drives the winch 36 to rotate. The winch 36 drives the traction cable 37 to move, causing the traction cable 37 to pull the traction connecting frame 38 and the precast component upward, thus lifting one end of the precast component.

[0027] like Figure 2 , Figure 6 and Figure 7As shown, the second motor 32 is fixedly installed at the bottom of the movable bracket 30. A stop block 12 is fixedly installed on one side of the rectangular support plate 10. A first sliding block 33 is fixedly installed on one side of the bottom of the movable bracket 30. A second sliding block 34 is fixedly installed on the other side of the bottom of the mounting bracket 20. Both the first sliding block 33 and the second sliding block 34 are slidably installed inside the first guide rail 13. A right-angle transmission reducer 301 is fixedly installed at one end of the second motor 32. The right-angle transmission reducer 301 is fixedly installed inside the first sliding block 33. A second rotating wheel 302 is fixedly installed inside the right-angle transmission reducer 301. The second rotating wheel 302 is rotatably installed at the bottom of the movable bracket 30 and is driven by the second motor 32 through a right-angle transmission reducer. The device 301 drives the second rotating wheel 302 to rotate, which in turn drives the first sliding block 33, the second sliding block 34, and the moving bracket 30 to move along the first guide rail 13, so that the other end of the precast component contacts the stop block 12. The moving bracket 30 continues to move. Because the precast component is blocked by the stop block 12, and driven by the third motor 35, one end of the precast component is lifted, so that the precast component can be parallel and attached to the side wall of the tunnel. Then the stop block 12 is removed to anchor the precast component. Through the combined action of the moving bracket 30, the second motor 32, the third motor 35, and the winch 36, it is easy for workers to anchor the precast component to the side wall of the tunnel, reducing the manual operation steps of workers and reducing the labor intensity of workers.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, the lifting assembly 4 is located on top of the support assembly 1. The lifting assembly 4 includes a second hydraulic rod 40 and a third hydraulic rod 42. The second hydraulic rod 40 is fixedly installed inside the rectangular support plate 10. A first lifting plate 41 is fixedly installed at one end of the second hydraulic rod 40. A second guide rail 14 is located inside the first lifting plate 41. A third sliding block 44 is slidably installed inside the second guide rail 14. The third hydraulic rod 42 is fixedly installed on top of the third sliding block 44. A second lifting plate 43 is fixedly installed at one end of the third hydraulic rod 42. When installing the precast components at the top of the tunnel, the second hydraulic rod 40 extends, driving the first lifting plate 43. 1. The precast component is in contact with the bottom of the precast component. The precast component on the rectangular support plate 10 is lifted once by the second hydraulic rod 40. After the first lifting is in place, the third hydraulic rod 42 is moved along the second guide rail 14 by the third sliding block 44, so that the third hydraulic rod 42 slides under the precast component. Then, the third hydraulic rod 42 drives the second lifting plate 43 to contact the bottom of the precast component, and lifts the precast component a second time until the precast component is in contact with the top of the tunnel. With the combined action of the second hydraulic rod 40 and the third hydraulic rod 42, no manual intervention is required for the precast component, which facilitates the anchoring of the precast component on the top of the tunnel and improves work efficiency.

[0029] The working principle of this prefabricated assembly equipment used in urban rail transit projects will be explained in detail below.

[0030] like Figure 1-7 As shown, when using this prefabricated assembly equipment for urban rail transit projects, tracks are laid inside the subway tunnel where construction is needed. Prefabricated components are hoisted according to their location. If prefabricated components are to be installed on the tunnel sidewalls and top, external hoisting equipment is used to place them on top of support columns 11. Support columns 11 maintain a certain distance between the prefabricated components and the rectangular support plate 10, facilitating movement of the prefabricated components by the installation assembly 3 and lifting assembly 4. The first motor 23 drives the first rotating wheel 21 to rotate via a dual-output reducer 22, thus moving the equipment. The rectangular support plate 10, the first rotating wheel 21, and the first motor 23 together form a moving device. Tracks are laid inside the tunnel, and the first motor 23 and the first rotating wheel 21 move the moving device along the tracks, transporting the prefabricated components into the tunnel. This allows installation of prefabricated components to be carried out from inside the tunnel, reducing the probability of collisions with steel beams and preventing safety accidents. After the prefabricated components are delivered to their designated positions... The second hook 39 hooks onto the end of the precast component, and the third motor 35 drives the winch 36 to rotate. The winch 36 moves the traction cable 37, causing the traction cable 37 to pull the traction connecting frame 38 and the precast component upward, lifting one end of the precast component. At the same time, the second motor 32 drives the second rotating wheel 302 to rotate through the right-angle transmission reducer 301, causing the first sliding block 33, the second sliding block 34, and the moving bracket 30 to move along the first guide rail 13, so that the other end of the precast component is aligned with the stop block. When the 12 blocks are in contact, the movable support 30 continues to move. The maximum moving distance of the movable support 30 is limited by the limit block 15 to prevent the movable support 30 from detaching from the guide rail. As the precast component is blocked by the block 12, the lifting end of the precast component will continue to flip upward until the precast component can be parallel and attached to the side wall of the tunnel. Then the block 12 is removed to anchor the precast component, making it easier for workers to anchor the precast component to the side wall of the tunnel, reducing the manual operation steps of workers and reducing the labor intensity of workers. If the precast components at the top of the tunnel are to be installed, the second hydraulic rod 40 extends, causing the first lifting plate 41 to contact the bottom of the precast component. The second hydraulic rod 40 then lifts the precast component on the rectangular support plate 10 once. After the first lift is complete, the third sliding block 44 moves the third hydraulic rod 42 along the second guide rail 14, causing the third hydraulic rod 42 to slide below the precast component. Then, the third hydraulic rod 42 drives the second lifting plate 43 to contact the bottom of the precast component, performing a second lift until the precast component is fully lifted. The components fit snugly against the top of the tunnel, eliminating the need for manual intervention and facilitating anchoring of prefabricated components at the tunnel top, thus improving work efficiency. Simultaneously, the first hook 26 at the bottom of the rectangular support plate 10 can hook both ends of the prefabricated component, allowing the first hydraulic rod 24 to extend and lift the connecting plate 25 and the first hook 26 upwards, raising the prefabricated component off the ground for transport. This device can also transport subway rails, sleepers, and other components simultaneously, improving the efficiency of subway construction.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
