As shown in fig. 2A-5B, the present invention provides a shore bridge girder suspension system for suspending girders of a shore bridge, which includes a sea-side support structure 1 and a land-side support structure 2 oppositely disposed in a first direction. The first direction is, for example, the x direction in fig. 2A and 2B, and further is a direction from the sea side to the land side and from the land side to the sea side. Girder 3 passes through sea side bearing structure 1 and land side bearing structure 2's support in the bank bridge, sets up along first direction level, and girder 3 passes sea side bearing structure 1 and land side bearing structure 2 to extend along first direction. The girder 3 on the shore bridge can slide in a first direction, i.e. can move back and forth between the sea side and the land side.

Referring to fig. 6 and 7, fig. 6 is a partially enlarged view of the region S in fig. 2A, and fig. 7 is a schematic view of the view a in fig. 6, which corresponds to a cross-sectional view of the shore bridge at the position of the sea-side support structure, the cross-sectional view being perpendicular to the first direction. The longerons 3 also have 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 side direction, the sea side support structure 1 comprises oppositely arranged suspension plates 11, oppositely arranged sea side suspension linkage beams 12, oppositely arranged sea side upper press wheels 13 and oppositely arranged sea side lower press wheels 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 sea side lower pressing wheels 14, the crossbeam 3 is erected on the sea side lower pressing wheels 14, namely the sea side lower pressing wheels 14 are abutted against the lower surfaces of the lower chords of the crossbeam 3 and used for supporting the crossbeam 3, and the sea side suspension connecting beams 12 are connected with the crossbeam 3 through the sea side lower pressing wheels 14. Pinch roller 13 butt on the sea side of the left and right sides is on the upper chord of girder 3 to girder 3 is located between pinch roller 13 and the pinch roller 14 under the sea side on the sea side in vertical direction, vertical direction for example for in FIG. 2A and 7 the setting is erect to pinch roller 13 and the pinch roller 14 under the sea side on the sea side of the z direction in, when girder 3 slides along the first direction, take place relative slip with pinch roller 13 and the pinch roller 14 under the sea side on the sea side, and drive pinch roller 13 and the roll of pinch roller 14 under the sea side on the side. The lower extreme and the sea side of hanger plate 11 hang connection beam 12 fixed connection, and the upper end is connected on sea side bearing structure through round pin axle 111, and further sea side bearing structure includes sea side frame 15, and the upper end of hanger plate 11 is connected on sea side frame 15 through round pin axle 111, and sea side hangs connection beam 12 and hangs on sea side frame 15 through hanger plate 11. The present invention provides the longerons 3 between the two sets of sea side suspension tie beams 12, i.e., the vertical walls 31 are located on the opposite inner sides of the left sea side suspension tie beam 12 and the vertical walls 32 are located on the opposite inner sides of the right sea side suspension tie beam 12.

Fig. 1 shows a sea-side support structure 70 of a suspension system in the prior art, which includes a frame 71 for fixing elements, sea-side suspension connecting beams 72 arranged laterally opposite to each other, a sea-side upper press wheel 73, and a sea-side lower press wheel 74 for supporting a girder 80. The longerons 80 have laterally oppositely disposed

vertical walls

81 and 82. The topside upper pinch roller 73 is fixed to the frame 71 and the topside lower pinch roller 74 is adapted to receive the longerons 80. The upper end of the suspension plate 721 would also be fixed to the frame 71 by the pin 722 in the prior art, and the suspension plate 721 and the pin 722 would be arranged directly above the sea side suspension connection beam 72 due to the suspension of the sea side suspension connection beam 72, however, such arrangement would result in additional bending moment of the suspension structure due to the girder system load.

To this end, applicants contemplate placing the pins in a position that is collinear with the topside upper puck 13,

vertical walls

31 and 32, and the topside lower puck 14. So that the pin and sea side suspension link beam are laterally displaced, the inventors have conceived of providing the hanger plate 11 in the form of a bent plate to solve the problem of co-linearity and suspension of the sea side suspension link beam. If the hanging plate is arranged in a bending mode to achieve the purpose that the hanging plate is connected with the pin shaft and the sea side suspension connecting beam, the abrasion of the hanging plate can be accelerated. And the structure of the arc-shaped bent plate is more stable and firm. Further, the suspension plate 11 of the present embodiment is a bent plate that is concave downward, so that a sufficient space for installing other components can be left below the suspension plate 11, such as the sea-side upper roller 13 in the present embodiment, and the sea-side upper roller 13 is also fixed to the sea-side frame 15 above. The oppositely arranged hanger plates 11 in this embodiment form an open hook type structure.

Referring to fig. 2B-5B, as well as fig. 7 and 12A-12B, the sea-side support structure 1 further comprises sea-side horizontal lateral wheels 16 arranged laterally opposite to each other, a vertical wall 31 and a vertical wall 32 being laterally located between the sea-side horizontal lateral wheels 16 arranged opposite to each other, the position of the sea-side horizontal lateral wheels 16 in the lateral direction being fixed, so that the sea-side horizontal lateral wheels 16 in the lateral direction can act as a limit for the

vertical walls

31, 32. Specifically, 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 16 mm. That is, the rolling surface of the sea-side horizontal side phase wheel 16 is laterally spaced from its adjacent vertical wall by a minimum distance of 6-16 mm. For example, the rolling surface on the right side of the sea-side horizontal lateral wheel 16 on the left in fig. 7 is spaced 6-16mm from the adjacent vertical wall 31, and the rolling surface on the left side of the sea-side horizontal lateral wheel 16 on the right is spaced 6-16mm from the adjacent vertical wall 32. Further, the above-mentioned interval may be 10-14 mm. Swing takes place at the side direction when vertical wall, can with the horizontal side direction wheel butt of neighbouring sea side to the horizontal side direction wheel of sea side can realize spacingly to vertical wall. The distance between the sea side horizontal side wheels 16 and the

vertical walls

31 and 32 is set to be 6-16mm in the lateral direction, and the sea side horizontal side wheels 16 are not directly abutted against the vertical walls, so that the requirement that the girder can generate micro-motion displacement in the lateral direction is met, and the vertical walls are prevented from being clamped by the sea side horizontal side wheels.

In the present embodiment, the plane of the sea-side horizontal lateral wheels 16 is horizontally disposed, in fig. 7, when the vertical wall 31 swings to the left, the rolling surface of the sea-side horizontal lateral wheel 16 on the left side abuts against the vertical wall 31 in the lateral direction, and when the vertical wall 32 swings to the right, the rolling surface of the sea-side horizontal lateral wheel 16 on the right side abuts against the vertical wall 32 in the lateral direction.

With the prior art sea side support structure 70 shown in FIG. 1, longerons 80 are susceptible to twisting due to offset loading, i.e., lateral deflection, as they slip between the sea side and the land side. For this purpose, in the prior art, fixing rods 75 are provided laterally 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, the fixing rods 75 being fixedly connected to the frame 71 and the vertical wall 81, and the fixing rods 75 being fixedly connected to the frame 71 and the vertical wall 82, so as to limit the movement of the girder 80 in the lateral direction, for example, the side-to-side movement as shown in fig. 1. Thus, at the sea side, longerons 80 are fixed laterally.

In the shore bridge girder suspension system, the sea-side horizontal lateral wheel has a guiding effect on the girder, and can limit the movement of the girder in the lateral direction because the sea-side horizontal lateral wheel is fixed in the lateral direction. Thereby eliminating the need for a fixed rod as in the prior art. In addition, the crossbeam is erected on the sea side lower pressure wheel and is supported by the sea side lower pressure wheel, the sea side lower pressure wheel is fixedly connected with the sea side suspension connecting beam, and the sea side suspension connecting beam is suspended through the hanging plate and the pin shaft, so that the requirement for the lateral micro-motion displacement of the crossbeam is met.

Referring to fig. 12A and 12B, further, spacers 33 may be provided on the

vertical walls

31 and 32 of the girder, the spacers 33 being located laterally between the rolling surface of the sea-side horizontal lateral wheel 16 and the adjacent vertical wall, thereby reducing the lateral spacing between the sea-side horizontal lateral wheel and the vertical wall, which may be reduced to 2-4mm, further 2-3 mm. Further, the spacers 33 may be provided at positions where the vertical walls of the girders 3 are opposed to the sea-side horizontal lateral wheels 16 when the girders 3 do not move, and at positions where the vertical walls of the girders 3 are opposed to the sea-side horizontal lateral wheels 16 when the girders 3 move back and forth, the above-mentioned 6-16mm lateral gap may be present, thereby reducing friction when the girders 3 move back and forth, and providing the spacers 33 at the fixing positions of the girders 3 to reduce lateral swing when the girders 3 are fixed. As shown in fig. 2A to 5B, which respectively show C, D, E, F four fixed positions of the girder 3, i.e. the fixed positions relative to the sea-side horizontal side phase wheel 16, the spacers 33 may be disposed at the four fixed positions, and no spacer is disposed on the vertical wall of the girder except C, D, E, F, so as to facilitate the sliding movement of the girder in the first direction and reduce the friction between the vertical wall of the girder and the sea-side horizontal side wheel. In this embodiment the four locations C, D, E, F of the longerons are fixed, in other embodiments the fixing locations of the longerons are different, and therefore the arrangement of the shims can be arranged according to the actual fixing locations of the longerons.

Further, in the above embodiments, a limiting assembly is further provided between the lateral upper vertical wall 31 and the vertical wall 32 and the respective adjacent sea side suspension coupling beam 12, for limiting the displacement of the vertical walls in the lateral direction. Due to the gap between the two sets of sea side suspension connecting beams 12 and the adjacent

vertical walls

31 and 32, the relative position between the sea side suspension connecting beams 12 changes when the girder is displaced laterally. For example, referring to fig. 5, if the longerons move to the left, the left vertical wall 31 will tend to hang the tie beam 12 laterally closer to the sea side, and will abut against the longerons due to the stop assembly 4, somewhat limiting their continued movement to the left. In this embodiment, the position limiting assembly 4 can be arranged on the sea side suspension coupling beam 12 and fixedly connected. If the girder moves to the right, the movement of the girder is also limited by the right-hand limiting assembly 4.

Further, referring to fig. 7 to 9, the stop assembly 4 comprises a return spring for transmitting lateral forces to its adjacent vertical wall. Specifically, as shown in fig. 7, the limit component 4 is fixed on the sea side suspension connecting beam 12, when the girder moves to the left, the limit component 4 on the left side is touched and applies a leftward force to the limit component 4, and when the limit component 4 receives the leftward force, the limit component transmits an elastic force in an opposite direction through the restoring elastic member 41, that is, the elastic force of the restoring elastic member transmits a rightward lateral force to the vertical wall 31, so that the girder 3 is restored.

In the above embodiment, the return elastic member may be a return spring extending in a lateral direction, and the elastic force direction of the return spring is in the lateral direction, and the return spring can give a reverse elastic force when the return spring is subjected to a lateral pressure from the vertical wall. Optionally, the elastic restoring member of the present embodiment includes a restoring spring 41 with an elastic force in a vertical direction, and the limiting assembly 4 further includes an edge wheel 42 vertically disposed with respect to the first direction, that is, the surface of the edge wheel 42 is perpendicular to the first direction, and the rolling surfaces of the edge wheel 42 disposed with respect to each other are abutted against the adjacent vertical wall 31 and the vertical wall 32, respectively. In addition, the limiting assembly 4 is further provided with a steering piece 43, the edge wheel 42 converts the received lateral force into vertical force through the steering piece 43 and transmits the vertical force to the return spring 42, the return spring 42 extending in the vertical direction is compressed due to the vertical pressure, opposite 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 therefore the lateral force is transmitted to the vertical wall, and the crossbeam is reset at the lateral position. As will be understood from fig. 4, when the vertical wall 31 is displaced leftward to push the edge wheel 42 leftward, the leftward force is converted into a compressive force downward against the return spring 41 by the turning member 43, and the upward elastic force of the return spring 41 gives the edge wheel 42 a rightward force by the turning member 43, and then the rightward force is transmitted to the vertical wall 31. If the girder 3 moves rightwards, the vertical wall 32 will push the right-side limiting component rightwards, the situation is similar to the above, and the description is omitted here.

Specifically, referring to fig. 9, the steering member 43 includes a central fixed shaft 431 and a connecting plate 432. The central fixing shaft 431 is connected with the edge wheel 42 and the return spring 41 through a connecting plate 432, and the central fixing shaft 431 and the edge wheel 42 are connected with the connecting plate 432 through a pin shaft in the embodiment. The upper end of the return spring 41 is fixedly connected to the connecting plate 432, for example, by welding. Edge wheel 42 is thereby caused to rotate in a first direction of rotation about central fixed axle 431 when subjected to vertical wall side forces. Referring to the arrows in fig. 9, 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 to the left in fig. 9, the end of the connecting plate 432 connected to the edge wheel 42 tilts up, which drives the edge wheel 42 to rotate counterclockwise around the central fixed shaft 431, and the end of the connecting plate 432 connected to the return spring 41 falls down, so that the return spring 41 moves downward. Edge wheel 42 applies downward pressure to return spring 41 through connecting plate 432. The return spring 41 is reset such that the end of the connecting plate 432 connected to the return spring 41 is tilted and the end connected to the edge wheel 42 is dropped, so that the edge wheel 42 rotates in the opposite direction to the first direction, for example, clockwise in fig. 9, around the central fixing shaft 431. The return spring 41 exerts a lateral force on the edge wheel 42 through the connecting plate 432. That is, the connecting plate 432 functions as a lever, and the center fixing shaft 431 functions as a fulcrum.

In the above embodiments, the sea side frame 15 and the sea side coupling beam 12 are open at the lower end thereof, so that the trolley on the shore bridge can pass through the sea side coupling beam 12 and the sea side frame 15 from the opening when moving in the first direction. The dolly can drive the goods and remove between sea side and land side, and the removal of dolly can not be hindered in open-ended design.

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 arranged opposite to each other in the first direction, so that the sea-side suspension linkage beam 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 arranged opposite to each other in the first direction, and the connecting rod 163 connects the

wheels

161, 162 across the sea-side suspension linkage beam 12.

In the above embodiments, referring to fig. 10-11, fig. 10 is a partially enlarged view of the region P in fig. 2A, and fig. 11 is a schematic view of the view angle B in fig. 10. The land-side support structure 2 comprises laterally oppositely disposed land-side horizontal side wheels 21, the positions of the land-side horizontal side wheels 21 are fixed in the lateral direction, and the

vertical walls

31 and 32 are laterally located between the oppositely disposed land-side horizontal side wheels 21 and abut against the land-side horizontal side wheels 21. Since the lateral position of the land-side horizontal-side phase wheel 21 is fixed, when abutting against the vertical wall, the girder 3 can be fixed in the lateral direction. The sea-side support structure 1 and the land-side support structure 2 can prevent the girder 3 from being excessively displaced in the lateral direction. Further, similar to the sea-side horizontal-side phase wheels, two wheels opposite to each other in the first direction may be provided for each set of the land-side horizontal-side phase wheels 21 in the present embodiment, and two sets of the land-side horizontal-side phase wheels 21 may be provided in the lateral direction. In addition, the land-side horizontal-side phase wheel 21 may be provided in the same configuration as the sea-side horizontal-side phase wheel 16.

Further, the land side supporting structure 2 further comprises a land side upper pressing wheel 22 and a land side lower pressing wheel 23, the land side upper pressing wheel 22 abuts against the upper surface of the upper chord of the girder 3, and the land side lower pressing wheel 23 is used for supporting the lower surface of the lower chord of the girder 3. Thereby realizing the suspension support of the girder 3.
