Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, specifically to a horizontally movable support device for the inner deck of a steel beam. Background Technology

[0002] The horizontally movable bridge deck lifting device for steel beams is a specialized piece of equipment used during bridge construction or maintenance for precisely lifting, temporarily supporting, and horizontally adjusting the bridge deck inside the steel beams. In use, the bridge jacking machine is placed on the beams and columns at the lower end of the bridge deck. An externally connected hydraulic system controls the longitudinal hydraulic cylinders to lift the bridge deck, while the lateral hydraulic cylinders push the longitudinal cylinders to move laterally, simultaneously causing the lifted bridge deck to move laterally.

[0003] When the longitudinal hydraulic cylinder lifts the bridge deck, it causes vibration, resulting in gravel and dust falling onto the support rails of the longitudinal hydraulic cylinder. This affects the smoothness of the movement when pushing the longitudinal hydraulic cylinder laterally, increasing the frequency of manual obstacle removal. In some narrow construction spaces, manual obstacle removal is extremely inconvenient. Therefore, a horizontally movable lifting device for the inner bridge deck of the steel beam is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a horizontally movable support device for the inner deck of a steel beam bridge, thereby solving the problems mentioned in the background art. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a horizontally movable support device for the inner deck of a steel beam bridge, comprising: A bridge jacking machine includes a track, a first fixed plate, a first hydraulic cylinder, a second hydraulic cylinder, and a connecting plate. The first fixed plate is fixed to one end of the track. The first hydraulic cylinder passes through and is fixed in the middle of the first fixed plate. There are two second hydraulic cylinders, which are fixed together by the connecting plate. One of them is rotatably connected to the piston rod of the first hydraulic cylinder, and the lower ends of the two second hydraulic cylinders are slidably connected to the track. The anti-blocking component includes a push plate, a second fixing plate, a support plate, and a spring column. The second fixing plate is welded to both sides of one end of the push plate and fixed to the base of the second hydraulic cylinder. The support plate is fixed to the side of the base of the second hydraulic cylinder. One end of the spring column is fixed to the support plate, and the other end is attached to the lower side of the push plate.

[0005] Furthermore, the anti-blocking component also includes a reinforcing plate, which is uniformly welded to the upper end of the push plate.

[0006] Furthermore, the anti-blocking component also includes a first opening and a threaded hole. The first opening is located in the middle of the second fixed plate, and the threaded hole is located at the four corners of the second hydraulic cylinder base. The first opening and the threaded hole are fastened together by bolts.

[0007] Furthermore, the lower end of the push plate is attached to the inner bottom surface of the track, and the two ends are attached to both sides of the track.

[0008] Furthermore, a rubber wheel is rotatably connected to the lower end of the second hydraulic cylinder base, and the rubber wheel is rolled on the inner bottom surface of the track.

[0009] Furthermore, it also includes a convenient component, which includes a second opening, a socket, and an L-shaped insert plate. The second opening is located at one end and the middle of one side of the track, the socket is located at the upper end of the second opening, and the L-shaped insert plate is inserted into the socket.

[0010] Furthermore, when the L-shaped insert is inserted into the socket, its lower end fits against the bottom surface of the second opening.

[0011] This utility model has the following beneficial effects: This invention, through the inclusion of an anti-clogging component, places the second fixing plate on the base of the second hydraulic cylinder, aligning the first opening with the threaded hole. Tightening the bolts causes the piston rod of the first hydraulic cylinder to move, pushing the second hydraulic cylinder to move as well. The movement of the second hydraulic cylinder causes the push plate on the side of the base to move, pushing away the gravel and dust on the track in the forward direction of the second hydraulic cylinder. Due to the resistance of the gravel and dust, the push plate is pressed down in the opposite direction and then lifted by the spring column on the support plate. This design, through a dynamic self-cleaning anti-clogging mechanism and modular, convenient maintenance design, completely solves the jamming problem caused by the accumulation of gravel and dust in existing lifting devices, while also reducing the need for manual intervention.
