For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 2A-5B, the present invention proposes a bridge girder suspension system for suspending a girder of a bridge, comprising a sea side support structure 1 and a land side support structure 2 arranged opposite in a first direction. The first direction is, for example, the x-direction in fig. 2A and 2B, and is further the direction from the sea side to the land side and from the land side to the sea side. The girders 3 in the shore bridge are horizontally arranged in a first direction by the support of the sea side support structure 1 and the land side support structure 2, and the girders 3 pass through the sea side support structure 1 and the land side support structure 2 and extend in the first direction. The girder 3 on the quay bridge can be slid in a first direction, i.e. can be moved back and forth between sea side and land side.

Referring to fig. 6 and 7, fig. 6 is a partially enlarged view of the S region of fig. 2A, and fig. 7 is a schematic view of the view a of fig. 6, corresponding to a cross-sectional view of the quay at the location of the sea-side supporting structure, the cross-section being perpendicular to the first direction. The girder 3 also has a lateral direction, for example the y-direction in fig. 2B and 7, which is perpendicular to the vertical plane, i.e. also perpendicular to the first direction. Along this lateral direction, the sea side support structure 1 comprises oppositely arranged hanger plates 11, oppositely arranged sea side suspension contact beams 12, oppositely arranged sea side upper pinch rollers 13 and oppositely arranged sea side lower pinch rollers 14.

Referring to fig. 7, the girder 3 has vertical walls 31 and 32, i.e., side walls on the left and right sides in the drawing. The lower ends of the sea side suspension connecting beams 12 on the left side and the right side are fixedly connected with the sea side lower pressing wheels 14, the girder 3 is erected on the sea side lower pressing wheels 14, namely, the sea side lower pressing wheels 14 are abutted below the lower chords of the girder 3 and used for supporting the girder 3, and the sea side lower pressing wheels 14 form the connection of the sea side suspension connecting beams 12 and the girder 3. The upper sea-side pinch rollers 13 on the left and right sides are abutted against the upper surface of the upper chord member of the girder 3, so that the girder 3 is positioned between the upper sea-side pinch rollers 13 and the lower sea-side pinch rollers 14 in the vertical direction, for example, the upper sea-side pinch rollers 13 and the lower sea-side pinch rollers 14 in the z direction in fig. 2A and 7 are vertically arranged, and when the girder 3 slides along the first direction, the girder slides relatively with the upper sea-side pinch rollers 13 and the lower sea-side pinch rollers 14 and drives the upper sea-side pinch rollers 13 and the lower sea-side pinch rollers 14 to roll. The lower end of the hanger plate 11 is fixedly connected with the sea side suspension contact beam 12, the upper end is connected to a sea side supporting structure through a pin shaft 111, the sea side supporting structure further comprises a sea side frame 15, the upper end of the hanger plate 11 is connected to the sea side frame 15 through the pin shaft 111, and the sea side suspension contact beam 12 is suspended on the sea side frame 15 through the hanger plate 11. The present invention provides for the placement of the longeron 3 between two sets of sea side suspension contact beams 12, namely with the vertical wall 31 being located on the opposite inner side of the left sea side suspension contact beam 12 and the vertical wall 32 being located on the opposite inner side of the right sea side suspension contact beam 12.

Fig. 1 shows a prior art sea side support structure 70 for a suspension system comprising a frame 71 for holding the elements, sea side suspension contact beams 72 arranged laterally opposite each other, a sea side upper pinch roller 73, a sea side lower pinch roller 74 for supporting a girder 80. The girder 80 has opposite vertical walls 81 and 82 in the lateral direction. The upper sea puck 73 is secured to the frame 71 and the lower sea puck 74 is for receiving a girder 80. The upper end of the hanger plate 721 is also secured to the frame 71 by a pin 722 in the prior art, and since the sea side suspension contact beam 72 is to be suspended, the hanger plate 721 and pin 722 are disposed directly above the sea side suspension contact beam 72, however, such an arrangement can result in additional bending moment of the girder system load to the suspension structure.

To this end, the applicant contemplates locating the pins in a position that is collinear with the topside upper puck 13, the vertical walls 31 and 32, and the topside lower puck 14. In this way, misalignment between the pin and the sea side suspension bridge occurs in the lateral direction, and the inventors have conceived to provide the hanger plate 11 in the form of a bent plate, thereby solving the problems of collineation and suspension of the sea side suspension bridge. If the hanger plate is arranged in a bent mode to achieve the purposes of the hanger plate connecting pin shaft and the sea side hanging connecting beam, the abrasion of the hanger plate can be accelerated. And the structure of the arc-shaped bent plate is more stable and firm. Further, the hanger plate 11 of the present embodiment is a downward concave bent plate, so that a sufficient space can be left below the hanger plate 11 for providing other components, for example, the on-sea pinch roller 13 in the present embodiment, and the on-sea pinch roller 13 is also fixed to the above-sea frame 15. The opposite hanging plates 11 in this embodiment form an open hook structure.

Referring to fig. 2B-5B, and fig. 7 and 12A-12B, the sea side support structure 1 further comprises sea side horizontal lateral wheels 16 disposed laterally opposite each other, with the vertical walls 31 and 32 laterally located between the oppositely disposed sea side horizontal lateral wheels 16, the sea side horizontal lateral wheels 16 being laterally fixed in position so that the sea side horizontal lateral wheels 16 can act as a stop for the vertical walls 31, 32 laterally. In particular, the spacing between the rolling surface of each sea-side horizontal lateral wheel 16 and its adjacent vertical wall in the lateral direction is 6-16mm, including 6mm and 16mm. That is, the minimum distance between the rolling surface of the sea-side horizontal lateral wheel 16 and its adjacent vertical wall in the lateral direction is 6-16mm. For example, the distance between the rolling surface on the right of the left sea-side horizontal lateral wheel 16 and the adjacent vertical wall 31 in fig. 7 is 6-16mm, and the distance between the rolling surface on the left of the right sea-side horizontal lateral wheel 16 and the adjacent vertical wall 32 is 6-16mm. Further, the above-mentioned interval may be 10-14mm. When the vertical wall swings sideways, it will abut the adjacent sea-side horizontal lateral wheel 16, so that the sea-side horizontal lateral wheel 16 will limit the vertical wall. The sea side horizontal lateral wheels 16 and the vertical walls 31 and 32 are laterally arranged at intervals of 6-16mm, instead of directly abutting the sea side horizontal lateral wheels 16 with the vertical walls, so that the condition that the girder can perform micro-motion displacement in the lateral direction is met, and the sea side horizontal lateral wheels 16 are prevented from clamping the vertical walls.

In this embodiment, the plane on which the sea-side horizontal lateral wheel 16 is located is horizontally disposed, in fig. 7, when the vertical wall 31 swings leftwards, the rolling surface of the sea-side horizontal lateral wheel 16 on the left is in lateral abutment with the vertical wall 31, and when the vertical wall 32 swings rightwards, the rolling surface of the sea-side horizontal lateral wheel 16 on the right is in lateral abutment with the vertical wall 32.

As shown in the prior art sea side support structure 70 of fig. 1, the girders 80 are susceptible to torsion due to unbalanced loading, i.e., lateral deflection, when sliding between sea and land sides. For this reason, in the prior art, fixing rods 75 are provided between the frame 71 and the vertical wall 81 of the girder 80 of the suspension system and between the frame 71 and the vertical wall 82 in the lateral direction, and the fixing rods 75 are fixedly connected to the frame 71 and the vertical wall 81, and the fixing rods 75 are fixedly connected to the frame 71 and the vertical wall 82, thereby restricting the girder 80 from moving in the lateral direction, for example, from moving left to right as shown in fig. 1. Thus, on the sea side, the girders 80 are fixed in the lateral direction.

In the present quay girder suspension system, the sea-side horizontal lateral wheels 16 have a guiding effect on the girder, and at the same time, since they are fixed in the lateral direction, the movement of the girder can be restrained in the lateral direction. Thereby omitting the fixing rod in the prior art. In addition, because the girder is erected on the sea side lower pressing wheel and is supported by the sea side lower pressing wheel, the sea side lower pressing wheel is fixedly connected with the sea side suspension connecting beam, and the sea side suspension connecting beam is suspended by the hanging plate and the pin shaft, thereby meeting the micro-motion displacement of the girder in the side direction.

Referring to fig. 12A and 12B, further, shims 33 may be provided on the vertical walls 31 and 32 of the girder, the shims 33 being laterally located between the rolling surface of the sea-side horizontal lateral wheels 16 and the adjacent vertical wall, thereby reducing the lateral spacing between the sea-side horizontal lateral wheels 16 and the vertical wall, which may be reduced to 2-4mm, and further may be 2-3mm. Further, shims 33 may be provided at positions where the vertical wall of the girder 3 is opposite to the sea-side horizontal lateral wheels 16 when no movement occurs, and no shims are provided at positions where the girder 3 is opposite to the sea-side horizontal lateral wheels 16 when the girder 3 is moved back and forth, and the above-mentioned 6-16mm lateral gap exists, thereby reducing friction when the girder 3 is moved back and forth, and shims 33 are provided at fixed positions of the girder 3 to reduce lateral swinging when the girder 3 is fixed. Fig. 2 a-5 b show several fixed positions of the girder 3, C, D, E, F four positions, respectively, i.e. fixed positions relative to the sea-side horizontal lateral wheels 16, at which the shims 33 may be arranged, whereas no shims are arranged on the vertical walls of the girder except for the four positions C, D, E, F, so as to facilitate the girder to slide in the first direction and reduce friction between the vertical walls of the girder and the sea-side horizontal lateral wheels 16. In this embodiment, the girder has four positions C, D, E, F fixed, and in other embodiments, the fixed positions of the girder are different, so that the arrangement of the shims can be set according to the actual fixed positions of the girder.

Further, in each of the above embodiments, a stopper assembly is further provided between the lateral vertical walls 31 and 32 and the respective adjacent sea side suspension contact beams 12 for restricting displacement of the vertical walls in the lateral direction. Due to the gap between the two sets of sea side suspension contact beams 12 and their adjacent vertical walls 31 and 32, respectively, the relative position with the sea side suspension contact beams 12 will change when the girder is laterally displaced. For example, referring to fig. 5 a-5 b, if the girder moves to the left, the left vertical wall 31 will tend to approach the sea side suspension bridge 12 in a lateral direction, and will abut the girder due to the action of the stop assembly 4, limiting its continued movement to the left to some extent. In this embodiment, the spacing assembly 4 may be disposed on the sea side suspension contact beam 12 and fixedly connected. If the large Liang Xiangyou moves, the limiting assembly 4 on the right side also limits its movement.

Further, with reference to fig. 7 to 9, the stop assembly 4 comprises a return spring for transmitting lateral forces to its adjacent vertical wall. Specifically, with reference to fig. 7, the limiting component 4 is fixed on the sea side suspension bridge 12, when the girder moves leftwards, the limiting component 4 on the left side is touched and applies a leftwards force to the limiting component 4, and when the limiting component 4 receives the leftwards force, the elastic force in the opposite direction is transmitted through the reset elastic member 41, that is, the rightward lateral force is transmitted to the vertical wall 31 through the elastic force of the reset elastic member, so that the girder 3 is reset.

In the above embodiment, the return elastic member may be a return spring extending in a lateral direction, and the direction of elastic force of the return spring is lateral, and the return spring can give a reverse elastic force when the return spring receives a lateral pressure from the vertical wall. Optionally, the reset elastic member of the present embodiment includes a reset spring 41 with an elastic force in a vertical direction, and the limiting assembly 4 further includes an edge wheel 42 vertically disposed relative to the first direction, that is, a surface of the edge wheel 42 is perpendicular to the first direction, and rolling surfaces of the edge wheels 42 disposed opposite to each other are respectively abutted against the vertical wall 31 and the vertical wall 32 adjacent thereto. In addition, the limiting assembly 4 is further provided with a steering piece 43, the edge wheel 42 converts the received lateral force into a force in the vertical direction through the steering piece 43 to be transmitted to the reset spring 41, the reset spring 41 extending in the vertical direction is compressed due to the fact that the force in the vertical direction is received, reverse vertical elastic force can be released, the vertical elastic force is converted into the lateral force through the steering piece 43 and then transmitted to the edge wheel 42, and accordingly the lateral force is transmitted to the vertical wall, and the girder is reset in the lateral position. As can be appreciated with reference to fig. 4 a-4 b, when the vertical wall 31 is displaced leftward, pushing the edge wheel 42 leftward, the leftward force is converted into a compressive force of the return spring 41 downward by the deflector 43, the upward elastic force of the return spring 41 imparts a rightward force to the edge wheel 42 by the deflector 43, and the rightward force is transmitted to the vertical wall 31. If the girder 3 moves rightward, the vertical wall 32 will push the right limiting component rightward, and the situation is similar to that described above, and will not be described again here.

Specifically, referring to fig. 9, the diverting member 43 includes a central fixed shaft 431 and a connection plate 432. The center fixed shaft 431 is connected with the edge wheel 42 and the return spring 41 through a connection plate 432, and the center fixed shaft 431 and the edge wheel 42 are connected with the connection plate 432 through a pin shaft in the present embodiment. The upper end of the return spring 41 is fixedly connected to the connection plate 432, for example, by welding. Thus, the edge wheel 42 is caused to rotate in a first direction about the central fixed axle 431 when subjected to vertical wall side forces. Referring to the arrows in fig. 9, the two arrows in fig. 9 represent the moving directions of the edge wheel 42 and the return spring 41, respectively, for example, when the vertical wall 31 moves leftwards in fig. 9, the end of the connection plate 432 connected with the edge wheel 42 is tilted, the edge wheel 42 is driven to rotate anticlockwise around the central fixed shaft 431, and the end of the connection plate 432 connected with the return spring 41 falls down, so that the return spring 41 falls down. The edge wheel 42 applies downward pressure to the return spring 41 through the web 432. The return spring 41 is turned up at the time of return, and the end of the connection plate 432 connected to the return spring 41 is dropped, so that the edge wheel 42 rotates around the center fixed shaft 431 in the opposite direction to the first direction, for example, in the clockwise direction in fig. 9. The return spring 41 applies a lateral force to the edge wheel 42 through the web 432. That is, the connection plate 432 corresponds to the lever action, and the center fixing shaft 431 corresponds to the fulcrum.

In the above embodiments, the sea side frame 15 and the sea side contact beams 12 are opened at the lower ends thereof, so that the trolley on the quay can pass through the sea side contact beams 12 and the sea side frame 15 from the opening when moving in the first direction. The trolley can drive the goods to move between the sea side and the land side, and the movement of the trolley is not hindered by the design of the opening.

In the above embodiments, referring to fig. 2B-5B and fig. 12A, 12B, each set of sea side horizontal lateral wheels 16 has two wheels 161, 162 disposed opposite in the first direction such that the sea side suspension bridge 12 is located between the two wheels 161, 162 in the first direction, i.e., on each set of sea side horizontal lateral wheels 16, the wheels 161, 162 are disposed opposite in the first direction, and the connecting rod 163 connects the wheels 161, 162 across the sea side suspension bridge 12.

In the above embodiments, referring to fig. 10-11, fig. 10 is a partial enlarged view of the P region in fig. 2A, and fig. 11 is a schematic view of the B region in fig. 10. The land side support structure 2 includes laterally oppositely disposed land side horizontal lateral wheels 21, the land side horizontal lateral wheels 21 being fixed in position in the lateral direction, and the vertical walls 31 and 32 being laterally located between the oppositely disposed land side horizontal lateral wheels 21 and abutting the land side horizontal lateral wheels 21. Due to the lateral position fixation of the land-side horizontal lateral wheels 21, fixation of the girder 3 in lateral direction can be achieved when abutting against the vertical wall. By the above sea side support structure 1 and land side support structure 2, excessive displacement of the girder 3 in the lateral direction can be avoided. Further, similar to the sea-side horizontal lateral wheels 16 described above, each set of land-side horizontal lateral wheels 21 in the present embodiment may be provided with two wheels opposing in the first direction, and two sets of land-side horizontal lateral wheels 21 are provided in the lateral direction. In addition, the land-side horizontal lateral wheels 21 may be provided in the same structure as the sea-side horizontal lateral wheels 16.

Further, the land side support structure 2 further includes a land side upper pinch roller 22 and a land side lower pinch roller 23, the land side upper pinch roller 22 being abutted on the upper chord of the girder 3, the land side lower pinch roller 23 being for supporting the lower face of the lower chord of the girder 3. Thereby achieving a suspension support for the girder 3. In addition, the land side support structure 2 further includes a land side frame 24, and the land side horizontal lateral wheels 21, the land side upper pinch wheels 22, and the land side lower pinch wheels 23 are fixed to the land side frame 24. The land-side horizontal lateral wheels 21, the land-side upper pinch wheels 22, and the land-side lower pinch wheels 23 of this embodiment are fixedly connected to the land-side frame 24 without displacement, thereby integrally forming a fixed support structure. While the undersea pinch roller 14 in the sea side support structure 1 is fixed to the sea side suspension contact beam 12, the sea side suspension contact beam 12 is connected to the sea side frame 15 by a pin, so that the sea side support structure portion supporting the girder 3 can slightly swing sideways.
