Description

Applicable to end support system and support method of horizontal rotating steel bridge

technical field

The invention relates to an end support system and a support method suitable for a horizontally rotating steel bridge. It is suitable for municipal transportation and sluice fields, and is specifically used in the occasion of horizontally rotating movable steel bridges.

Background technique

The horizontal rotating movable steel bridge is mainly used in the municipal and sluice fields, and the sluice field is more extensive. In the open state, road wheels are often of different tonnages and types, so it is an alternating load for the end. The traditional mode is to use the screw machine to support it in place and carry it, and the long-term alternating load on the screw will cause fatigue damage. , greatly shortening its lifespan. In addition, the screw machine is an important purchased part of the horizontal rotating steel bridge, and its price is expensive. If it is not selected properly, it will be damaged due to the existence of the alternating load of the vehicle, which will affect the safety of passing vehicles.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide an end support system and a support method for a horizontally rotating steel bridge with simple structure, convenient manufacture and low cost, aiming at the above-mentioned problems.

The technical scheme adopted in 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, which is characterized in that it includes:

Supporting wedge-shaped frame, which can be cushioned between the steel bridge and the civil construction below, and can be moved back and forth along the length of the steel bridge and set at the bottom of the steel bridge;

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

The supporting wedge-shaped frame is installed on the bottom of the steel bridge via guide rails arranged along the length direction of the steel bridge.

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 through a push rod bracket, and the other end of the electric push rod is connected to the support wedge frame.

A support method suitable for the end support system of a horizontally rotating steel bridge, characterized in that:

When the steel bridge rotates horizontally to the state that can be opened to traffic, the screw machine extends downward and the screw is supported on the cushion block of the civil construction below;

Obtain the pressure on the screw of the screw machine. When the pressure reaches the design requirements, the screw machine stops moving;

The drive mechanism drives the support wedge frame to move between the steel bridge and the pad along the length of the steel bridge until the support wedge frame is cushioned between the steel bridge and the civil works;

The screw machine retracts the screw.

The beneficial effects of the present invention are as follows: the present invention realizes that the screw machine is supported on the civil works through the support wedge-shaped frame in the open state through the cooperation of the support wedge frame and the screw machine, avoids damage to the screw machine, effectively saves the operating cost, and ensures Safe vehicle traffic.

1 to 3 are schematic diagrams of the work of the embodiment.

Detailed ways

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 support wedge frame 3 .

In this example, the screw machine 5 has vertically arranged screws that can extend up and down, and spacers are provided on the civil works below the steel bridge corresponding to the screw machine 5 .

In this embodiment, the support wedge frame 3 is installed on the bottom of the steel bridge through the guide rail 4, the guide rail 4 is arranged along the length direction of the steel bridge, the support wedge frame 3 can be moved along the guide rail and is installed on the guide rail 4, and the support wedge frame 3 is also connected with a drive The drive mechanism drives the support wedge frame to move back and forth in the guide rail 4 .

In this embodiment, the driving mechanism has an electric push rod 2 arranged along the length direction of the steel bridge.

The support method of the support system in this embodiment is as follows:

When the steel bridge is horizontally rotated to a state that can be opened to traffic (see Figure 1), the screw machine 5 extends downward and the screw is supported on the cushion block of the civil construction below;

Real-time acquisition of the pressure on the screw of the screw machine 5, when the pressure display reaches the design requirements, the screw machine stops moving;

The drive mechanism drives the support wedge frame 3 to move between the steel bridge and the pad along the length of the steel bridge until the support wedge frame is cushioned between the steel bridge and the civil works (see Figure 2);

The screw machine 5 retracts the screw, and the end of the steel bridge is pressed against the supporting wedge frame due to its own weight (see Figure 3), so as to ensure that the actual alternating load when the vehicle passes through acts on the supporting wedge frame 3, avoiding the direct impact of the screw machine. The force ensures the safety of the horizontally rotating movable steel bridge.
