Description

Technical Field

[0001] The present invention relates to an end support system and a support method for a horizontally rotating steel bridge, which are applicable to the fields of municipal transportation and sluice gates, and are particularly applicable to occasions of horizontally rotating movable steel bridges. Background Art

[0002] Horizontally rotating movable steel bridges are primarily used in municipal engineering and sluice gates, with sluice gates being a more common application. Their characteristic is that they need to rotate horizontally to a certain angle during typhoons to facilitate ship navigation. However, typhoons are rare throughout the year, and bridges are mostly open to traffic. Road wheels often have varying tonnages and types, creating an alternating load on the ends. Traditionally, screw extruders have been used to support the bridges, but long-term exposure to alternating loads can cause fatigue damage to the screws, significantly shortening their lifespan. Furthermore, the screw extruder is a key, expensive, and expensive component of horizontally rotating steel bridges. If improperly selected, the alternating loads can damage the extruders, compromising safety. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in response to the above-mentioned problems, a support system and support method for the end of a horizontally rotating steel bridge is provided which has a simple structure, is easy to manufacture and has a low cost.

[0004] The technical solution adopted by the present invention is: a support system for the end of a horizontally rotating steel bridge, which is arranged at one end of the steel bridge and has a screw machine, characterized in that it includes:

[0005] The supporting wedge frame can be placed between the steel bridge and the civil engineering below, and can be moved back and forth along the length of the steel bridge and installed at the bottom of the steel bridge;

[0006] The driving mechanism can drive the supporting wedge frame to move back and forth along the length direction of the steel bridge.

[0007] The supporting wedge frame is installed on the bottom of the steel bridge via a guide rail arranged along the length direction of the steel bridge.

[0008] The driving mechanism has an electric push rod arranged along the length direction of the steel bridge, one end of the electric push rod is connected to the steel bridge via a push rod bracket, and the other end of the electric push rod is connected to the supporting wedge frame.

[0009] A supporting method applicable to a horizontal rotating steel bridge end supporting system is characterized by:

[0010] When the steel bridge rotates horizontally to a state where it can be opened to traffic, the screw machine extends the screw downward to support the pads of the civil engineering below;

[0011] Obtain the pressure on the screw of the screw machine. When the pressure reaches the design requirement, the screw machine stops moving.

[0012] The driving mechanism drives the supporting wedge frame to move along the length direction of the steel bridge toward between the steel bridge and the pad until the supporting wedge frame is placed between the steel bridge and the civil engineering;

[0013] The screw machine retracts the screw.

[0014] The beneficial effect of the present invention is that the present invention cooperates with the supporting wedge frame and the screw machine, so that the screw machine is supported on the civil engineering through the supporting wedge frame when the vehicle is open to traffic, thereby avoiding damage to the screw machine, effectively saving operating costs, and ensuring the safety of vehicle traffic.

[0016] This embodiment is a support system for the end of a horizontally rotating steel bridge, which is arranged at one end of the steel bridge and has a screw machine 5 and a supporting wedge frame 3.

[0017] In this example, the screw machine 5 has a vertically arranged screw that can be extended and retracted up and down, and a pad is provided on the civil engineering below the steel bridge at a position corresponding to the screw machine 5.

[0018] In this embodiment, the supporting wedge frame 3 is installed at the bottom of the steel bridge via the guide rail 4. The guide rail 4 is arranged along the length direction of the steel bridge. The supporting wedge frame 3 can be installed on the guide rail 4 so as to be movable along the guide rail. The supporting wedge frame 3 is also connected to a driving mechanism, which drives the supporting wedge frame to move back and forth in the guide rail 4.

[0019] In this embodiment, the driving mechanism has an electric push rod 2 arranged along the length direction of the steel bridge. One end of the electric push rod 2 is connected to the steel bridge via a push rod bracket 1, and the other end of the electric push rod 2 is connected to a supporting wedge frame 3.

[0020] The supporting method of the supporting system in this embodiment is as follows:

[0021] When the steel bridge is rotated horizontally to the state where it can be opened to traffic (see Figure 1 ) When the screw machine 5 extends the screw downward and supports it on the pad of the civil engineering below;

[0022] The screw pressure of the screw machine 5 is obtained in real time. When the pressure reaches the design requirement, the screw machine stops.

[0023] The driving mechanism drives the supporting wedge frame 3 to move along the length direction of the steel bridge toward between the steel bridge and the pad until the supporting wedge frame is placed between the steel bridge and the civil engineering (see Figure 2 );

[0024] The screw machine 5 retracts the screw, and the end of the steel bridge is pressed tightly against the supporting wedge frame due to its own weight (see Figure 3), thereby ensuring that the alternating load when the actual vehicle passes is fully acted on the supporting wedge frame 3, avoiding direct force on the screw machine and ensuring the safety of the horizontal rotating movable steel bridge.
