The at least two beams comprise a first beam 110 and a second beam 120 which are arranged at intervals; the first pier body 210 and the second pier body 220 which are adjacent to each other in the at least three pier bodies are used for supporting the first beam body 110, and the second pier body 220 and the third pier body 230 which are adjacent to each other in the at least three pier bodies are used for supporting the second beam body 120; the first beam body 110 is fixedly connected with the first pier body 210, the first beam body 110 is movably connected with the second pier body 220, and the first beam body 110 can move in the longitudinal direction of the first beam body 110 relative to the second pier body 220; the second beam 120 is fixedly connected to the second pier 220, the second beam 120 is movably connected to the third pier 230, and the second beam 120 can move in the longitudinal direction of the second beam 120 relative to the third pier 230; the transformation method comprises the following steps: fixedly connecting the first beam body 110 with the second pier body 220; so as to transform the simply supported bridge into the monorail bridge of the present application described above.

In the embodiment of the application, the simply supported bridge is also a single-rail bridge.

In the embodiment of the present application, the beam, the first beam 110, the second beam 120, the pier, the first pier 210, the second pier 220, and the third pier 230 have been described above, and are not described herein again.

Here, the simply supported bridge is different from the above-described monorail bridge in that the first beam body 110 and the second beam body 120 are both fixed at one end and movable at the other end; as shown in fig. 8, in the case where the running device 300 runs on the basis of the first beam 110, the traction force or the braking force of the running device 300 can be borne by the first pier 210; as shown in fig. 9, in the case where the running device 300 runs on the basis of the second girder 120, the traction force or the braking force of the running device 300 can be borne by the second pier 220; that is, the simply supported bridge always takes on the traction or braking force of the traveling apparatus 300 based on one pier body; in fig. 8 and 9, F represents a traction force or a braking force, and Nx represents a force applied by the pier.

It should be noted that, since the first beam 110 and the second beam 120 are both fixed at one end and movable at the other end, a gap is formed between the first beam 110 and the second beam 120.

Here, in the case of fixedly connecting the first girder 110 and the second pier 220; when the running equipment 300 runs on the basis of the first beam body 110, the traction force or the braking force of the running equipment 300 can be shared by the first pier body 210 and the second pier body 220, so that the deformation caused by the traction force or the braking force of the running equipment 300 can be shared by the first pier body 210 and the second pier body 220, the deformation of one pier body is greatly reduced, and the running comfort of the running equipment 300 is improved; meanwhile, if the same pier body deformation is set, the first pier body 210 and the second pier body 220 can be set smaller, so that the size of the monorail bridge can be greatly reduced. In addition, since the first beam 110 is fixedly connected to the first pier 210 and the second pier 220, the first pier 210, the second pier 220 and the first beam 110 form an integral stressed structure; therefore, the first pier body 210, the second pier body 220 and the first beam body 110 are stressed together, and the deformation resistance of the monorail bridge is improved. Under the condition that the running equipment 300 is borne by the second beam 120, that is, the driving force of the running equipment 300 is mainly borne by the second beam 120, the first pier 210 and the second pier 220 can share the traction force or the braking force of the running equipment 300, so that the deformation caused by the traction force or the braking force of the running equipment 300 can be shared by the first pier 210 and the second pier 220, the deformation of one pier is greatly reduced, and the running comfort of the running equipment 300 is improved.

In this embodiment, the implementation manner of the movable connection between the first beam 110 and the second pier 220 is similar to the implementation manner of the movable connection between the second beam 120 and the third pier 230 in the longitudinal direction of the second beam 120, and is not described herein again.

Here, the longitudinal direction of the first beam 110 may be the longitudinal direction of the first beam 110, or may be substantially the longitudinal direction of the first beam 110.

Here, the longitudinal direction of the second beam 120 may be the longitudinal direction of the second beam 120, or may be substantially the longitudinal direction of the second beam 120.

In the embodiment of the present application, the manner of fixedly connecting the first beam 110 and the second pier 220 is not limited.

For example, the movable connecting seat between the first beam body 110 and the second pier body 220 is replaced by a fixed connecting seat; that is, the first beam 110 and the second pier 220 are movably connected based on a movable connecting seat, and the first beam 110 and the second pier 220 are fixedly connected based on a fixed connecting seat.

For another example, the first pier body 210 has a first connection hole, the first end of the first beam body 110 has a second connection hole, the second pier body 220 has a third connection hole and a fourth connection hole, the second end of the first beam body 110 has a fifth connection hole, the first end of the second beam body 120 has a sixth connection hole, the third pier body 230 has a seventh connection hole, and the second end of the second beam body 120 has an eighth connection hole; the monorail bridge may further comprise: the connecting device comprises a first connecting piece, a second connecting piece, a third connecting piece and a fourth connecting piece. The first connecting piece is inserted into the first connecting hole and the second connecting hole; the first end of the first beam body 110 is fixedly connected with the first pier body 210 through the first connecting piece; the second connecting piece is inserted into the third connecting hole and the fifth connecting hole; the second end of the first beam body 110 is movably connected with the second pier body 220 in the longitudinal direction of the first beam body 110 through the second connecting piece; the third connecting piece is inserted into the fourth connecting hole and the sixth connecting hole; the second beam body 120 is fixedly connected with the second pier body 220 through the third connecting piece; the fourth connecting piece is inserted in the seventh connecting hole and the eighth connecting hole; the second beam 120 is movably connected to the third pier 230 in the longitudinal direction of the second beam 120 through the fourth connecting member.

The first connection hole, the second connection hole, the fourth connection hole, the sixth connection hole, the seventh connection hole, the eighth connection hole, the first connection element, the third connection element, and the fourth connection element are similar to each other, and thus, description thereof is omitted.

In this example, the second end of the first beam 110 is movably connected to the second pier 220 in the longitudinal direction of the first beam 110 through the second connecting member, which is similar to the movable connection of the second beam 120 to the third pier 230 in the longitudinal direction of the second beam 120 through the fourth connecting member.

As an example, the shape of the portion of the second connecting member inserted into the third connecting hole matches the shape of the third connecting hole, so that the second connecting member is fixedly connected with the second pier body 220; the part of the second connecting piece inserted in the fifth connecting hole can move in the fifth connecting hole, so that the second connecting piece is movably connected with the second beam body 120; here, the fixedly connecting the first girder 110 and the second pier 220 may include: a fixing member is filled in a gap between the fifth connecting hole and the second connecting member, and the first beam 110 is fixedly connected to the second pier 220.

Here, the structure of the fixing member is not limited as long as the first girder 110 can be prevented from moving with respect to the second pier 220. For example, the fixing member may be a steel plate. Also for example, the fixing member may be a steel bar.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
