Description

A one-way helical bridge

technical field

The invention relates to the field of bridges, in particular to a one-way spiral bridge.

Background technique

The existing bridge structure consists of the lower piers, abutments and foundations and the upper span structure. In the traditional sense, bridge types are generally divided into girder bridges, arch bridges, suspension bridges and so on. Their common feature is that the bridge deck is horizontal and static.

Existing bridges are basically two-way traffic, unless artificially restricted, it is basically impossible to realize the function of one-way traffic, and the existing bridges are generally similar in structure, the bridge deck is smooth and stable, and the entertainment is poor. the

Contents of the invention

The technical problem to be solved by the present invention is to provide a one-way spiral bridge for the defects of the background technology, which can realize one-way passage under the premise that people can pass safely, and does not need personnel to guard.

The present invention adopts the following technical solutions for solving the problems of the technologies described above:

A one-way spiral bridge, comprising a central girder, several bridge plate units and a rotating device for making the central girder rotate at a uniform speed;

The bridge plate unit is evenly fixed on the center beam, at 90 degrees to the center beam, and the lengths on both sides of the center beam are equal;

The bridge plate units form a fixed angle to form a spiral structure along the axis of the center beam, and the angle between the bridge plate unit at one end of the center beam and the bridge plate unit at the other end of the center beam is greater than or equal to 60 degrees.

As a further optimization scheme of a one-way spiral bridge in the present invention, the bridge deck unit includes a sub-beam, a bridge deck and at least two bridge deck support structures, and the bridge deck is fixed on the sub-beam through the bridge deck support structure, so Said auxiliary beam passes through the central axis of the central beam and is fixed on the central beam.

As a further optimization scheme of the one-way spiral bridge of the present invention, the bridge plate unit further includes another bridge plate, which is symmetrically fixed on the other side of the subbeam through the bridge plate supporting structure.

As a further optimization scheme of a one-way spiral bridge in the present invention, the bridge deck support structure includes a supporting main girder, a bridge deck fixing plate and two supporting sub-beams, and the supporting main girder passes through the central axis of the sub-beam and is fixed on the On the sub-beam, the bridge plate fixing plate is fixed on the bridge plate, and the bridge plate fixing plate is respectively fixedly connected with two ends of the supporting main beam through two supporting sub-beams.

As a further optimization scheme of the one-way spiral bridge of the present invention, the central girder and the sub-beam of the bridge plate unit are cylindrical structures.

As a further optimization scheme of the one-way spiral bridge of the present invention, the bridge plate unit at one end of the center girder and the bridge plate unit at the other end of the center girder form a 90-degree angle.

Assuming that the whole bridge is composed of 45 bridge plates, the accumulated angle can reach 90 degrees. In addition, a horizontal bridge deck is moving laterally in the rotating deck of the constant speed of the bridge itself, and people can pass through the bridge following the movement of the horizontal deck.

A person walks about 0.5 meters per step, and the total length of the bridge is 90 degrees. It can be known that it takes about 20 seconds for a person to walk completely across the bridge. Therefore, the bridge rotates 4.5 degrees per second, and the degree of each bridge plate is 2 degrees, that is, for the bridge, the horizontal plane advances two and a half bridge plates in one second, that is, 0.5 meters. Because people will not have a bad feeling in the room on a plane less than 15 degrees, the bridge rotates about 4.5 degrees < 15 degrees per step, so people will not feel uncomfortable and can pass the bridge safely.

Compared with the prior art, the present invention adopts the above technical scheme and has the following technical effects:

When people walk, they need to walk under the rotation of the bridge. The direction of the bridge rotation is different, or counterclockwise or clockwise. People can pass the bridge in different directions. In this way, the bridge has the function of passing in a specific direction. It is a solution for one-way passing, and it has the characteristics of being a landmark building; in addition, as an entertainment activity, it can be used as an entertainment bridge. The speed of passing is different at different speeds, and the speed of people on the bridge is different, which can exercise children's intelligence. Agility and balance.

Detailed ways

Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

Assuming that there are 45 bridge plates, Figures 1, 2, and 3 are the overall schematic diagrams of the one-way helical bridge structure.

The bridge consists of a central girder, an auxiliary girder and a bridge deck. Each subframe is fixed to each bridge plate respectively, and the angle between each bridge plate is 2 degrees. The angle between the first bridge plate and the 45th bridge plate is 90 degrees.

Figure 4 and Figure 5 are detailed schematic diagrams of the bridge deck support structure. The supporting structure of the bridge deck is composed of supporting subbeams, supporting main girders and bridge deck fixing plates.

6-a to 6-e are schematic diagrams of a single row of a unidirectional helical bridge. This diagram explains how a one-way helical bridge works. From Figure 6-a to Figure 6-e, the one-way spiral bridge only rotates clockwise, and people walking on the bridge can pass through the bridge as the bridge rotates.

Assuming that the whole bridge is composed of 45 bridge plates, the accumulated angle can reach 90 degrees. In addition, a horizontal bridge deck is moving laterally in the rotating deck of the constant speed of the bridge itself, and people can pass through the bridge following the movement of the horizontal deck.

The left side of Figure 2 shows the rotating structure that drives the helical bridge, including the motor and gear combination. The motor is connected to the center beam through the gear combination. After the motor is started, the center beam rotates at a constant speed. People walk up the stairs, stand on the high platform, and pass through the helical bridge. .

A person walks about 0.5 meters per step, and the total length of the bridge is 90 degrees. It can be known that it takes about 20 seconds for a person to walk completely across the bridge. Therefore, the bridge rotates 4.5 degrees per second, and the degree of each bridge plate is 2 degrees, that is, for the bridge, the horizontal plane advances two and a half bridge plates in one second, that is, 0.5 meters. Because people will not have a bad feeling in the room on a plane less than 15 degrees, the bridge rotates about 4.5 degrees < 15 degrees per step, so people will not feel uncomfortable and can pass the bridge safely.
