It should be noted that, in the case of no conflict, the embodiments and technical features in the embodiments may be combined with each other, and the detailed description in the specific embodiments should be interpreted as an explanation of the gist of the present application and should not be construed as undue limitation to the present application.

In the description of the embodiments of the present application, the terms "upper," "lower," "top," "bottom," orientation or positional relationship are based on the orientation or positional relationship shown in fig. 5, and it should be understood that these orientation terms are merely for convenience of description of the present application and to simplify the description, rather than to indicate or imply that the devices or elements referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the present application. Referring to fig. 5, the up-down direction is the direction indicated by an arrow R1 in the figure.

In the description of the embodiment of the present application, the transverse direction is the direction indicated by the arrow R2 in the figure, taking fig. 6 as a reference, based on the azimuth and positional relationship shown in fig. 6.

As part of the inventive concept of the present application, before describing the embodiments of the present application, the reason why the height direction of the rail Liang Yangui beam is deviated in the related art needs to be analyzed, and the technical solution of the embodiments of the present application is obtained through reasonable analysis.

In the related art, referring to fig. 1, a suspension bridge generally includes a pier and a rail beam 1 suspended on the pier, the pier includes a pier body and a pier lifting lug 41 connected to the pier body, one end of the rail beam 1 is fixedly connected to the pier lifting lug 41 through a corresponding pin shaft, the corresponding pin shaft does not move relative to the lifting lug, in general, at least one end of the rail beam 1 is fixedly connected to the pier through the pin shaft, so as to prevent the rail beam 1 from moving, the other end of the rail beam 1 is mounted in a movable hole 100 of the pier lifting lug 41 through the corresponding pin shaft, the movable hole 100 on the pier lifting lug 41 does not rotate along the rail beam 1, the moving direction of the corresponding pin shaft in the movable hole 100 of the pier lifting lug 41 does not change, when the extending direction of the rail beam 1 changes, for example, the extending direction of the rail beam 1 changes, part of the rail beam 1 extends in the horizontal direction, part of the rail beam 1 is located on a slope so that the extending direction of the rail beam 1 forms a certain angle with the horizontal direction, all the movable holes 100 of the lifting lug 41 extend in the horizontal direction, the corresponding pin shaft moves in the horizontal direction, the movable hole 100 is caused by the horizontal direction, the corresponding pin shaft moves in the movable hole 100 in the same direction, and the moving direction of the rail beam 1 is not influenced by the moving direction of the corresponding pin shaft 1 in the moving direction of the movable hole 100, or the moving direction of the rail 1 is not influenced by the moving direction of the lifting shaft in the moving direction of the bridge 1. It should be noted that the height direction of the track beam 1 is perpendicular to the lateral direction and the extending direction of the track beam 1, and the vehicle runs substantially along the extending direction of the track beam 1. Referring to fig. 1, the extending direction of the track beams 1 in the figure is the arrangement direction of two adjacent track beams 1 on the slope, namely, the direction indicated by arrow R4 in the figure; in the figure, the height direction of the track beam 1 is perpendicular to the extending direction of the track beam 1, namely, the direction indicated by an arrow R3 in the figure, it can be seen from the figure that when the track beam 1 on the right side is stretched by cold and hot deformation to push the corresponding pin shaft to move horizontally and leftwards in the movable hole 100 of the bridge pier, the track beam 1 on the right side is lifted by a certain distance h along the height direction of the track beam 1, and the travelling comfort of the vehicle is affected.

Referring to fig. 2, when the extending direction of the movable hole 100 of the track beam 1 is the same as the extending direction of the track beam 1 on the slope, the moving direction of the corresponding pin in the movable hole 100 is the same as the extending direction of the track beam 1, the moving direction of the corresponding pin in the movable hole 100 is the same as the moving direction of the arrow R4, and when the track beam 1 on the right side is heated and stretched to push the corresponding pin to move in the movable hole 100, the track beam 1 on the right side is not lifted or sunk along the height direction of the track beam 1, and the height direction of the track beam 1 is the direction indicated by the arrow R3. However, in the arrangement manner of the extending direction of the movable hole 100 in fig. 2, the moving direction of the pin shaft has a certain included angle with the horizontal direction, when part of the track beams 1 are not on a slope but horizontally extend, that is, the extending direction of the track beams 1 is the horizontal direction, the track beams 1 are pushed by the cold and hot expansion to move in the movable hole 100 along the direction having a certain included angle with the horizontal direction, so that the horizontally extending track beams 1 are lifted or sunk along the height direction of the track beams 1, and the travelling comfort of the vehicle is affected.

As can be seen from the above-mentioned scheme, as the track beam 1 is continuously changed in the extending direction, for example, the track beam 1 horizontally extends for a distance and then extends along a slope for a distance, the movable hole 100 on the corresponding bridge pier of the suspended track beam 1 needs to be continuously changed along with the change of the extending direction of the track beam 1, so that the moving direction of the corresponding pin shaft in the movable hole 100 is basically consistent with the extending direction of the track beam 1, so as to ensure that the track beam 1 cannot be raised or lowered along the height direction of the track beam 1. Thus, the movable holes 100 of the pier lifting lugs 41 at different positions may be made different, and the pier lifting lugs 41 corresponding to different positions need to be customized for the corresponding positions, so that the manufacturing cost of the pier is high.

In view of this, an embodiment of the present application provides a middle suspension bridge, referring to fig. 3 and 4, the suspension bridge includes a track beam 1, a first pin 2, a second pin 3, and a bridge pier.

Each first pin shaft 2 penetrates through two first mounting holes 11 which are oppositely arranged, and one end of the track beam 1 is hung on the pier through the first pin shaft 2. Each second pin shaft 3 penetrates through two second mounting holes 12 which are oppositely arranged, and the other end of the track beam 1 is hung on the pier through the second pin shafts 3.

In this way, when the extending direction of the track beam 1 changes, the moving direction of the first pin shaft 2 in the first mounting hole 11 changes correspondingly, so that the moving direction of the first pin shaft 2 in the first mounting hole 11 can always keep substantially consistent with the extending direction of the track beam 1.

In one embodiment, referring to fig. 3 to 5, the track beam 1 is configured to limit the movement of the corresponding second pin 3 along the radial direction of the pin relative to the track beam 1.

The friction coefficient of the first pin shaft 2 and the second sliding plate 142 is smaller than that of the first pin shaft 2 and the Liang Diaoer body 141, so that abrasion of the first pin shaft 2 is reduced.

In one embodiment, the second sled 142 is a tetrafluoro sled.

It will be appreciated that the second slide plate 142 is not limited to a tetrafluoro slide plate, as long as the material of the second slide plate 142 is such that the coefficient of friction between the first pin 2 and the second slide plate 142 is less than the coefficient of friction between the first pin 2 and the Liang Diaoer body 141, which reduces wear of the first pin 2.

In an embodiment, referring to fig. 8, the second pin shaft 3 is inserted into the second mounting hole 12, and a certain assembly gap is reserved between the hole wall of the second mounting hole 12 and the second pin shaft 3.

It should be noted that, the assembly gap is generally smaller, so that the second pin shaft 3 cannot move along the radial direction of the second pin shaft 3 in the second mounting hole 12, and the assembly gap is only set to enable the second pin shaft 3 to pass through the second mounting hole 12 more smoothly in the process that the second pin shaft 3 passes through the second mounting hole 12, so as to facilitate the installation of the second pin shaft 3.

In an embodiment, an assembly gap may not be reserved between the hole wall of the second mounting hole 12 and the second pin 3, and the hole wall of the second mounting hole 12 abuts against the second pin 3.
