Description

Technical Field

[0001] This utility model relates to the technical field of under-bearing tied arch bridges, specifically to an approach bridge structure for an under-bearing tied arch bridge. Background Technology

[0002] In urban roads, tied arch bridges can serve as an important component of urban expressways, urban arterial roads, and urban ring roads, alleviating urban traffic pressure. When connecting bridges, approach bridges are needed to connect the main bridge to the embankment, guiding vehicles onto the bridge.

[0003] In the existing technology, when general approach bridges are spliced ​​together, they cannot be initially positioned, thus failing to enhance the stability of the connection. Furthermore, during the connection, the hangers cannot be limited, which may cause them to sway or shift, thereby affecting their stability and safety. Utility Model Content

The rotating blocks are equipped with connecting blocks on the side near the rotating grooves. The connecting blocks are equipped with limiting plates through the rotating grooves on the other side. This allows the bridge bodies to be spliced ​​and connected, and the reinforcing rods to be moved and inserted into the bridge body. This can enhance the connection effect between the bridge bodies and make the entire structure more stable. During connection, the limiting plates can limit the two sides of the hangers to prevent them from shaking or shifting, thus enhancing the stability and safety of the structure. They can also be separated for maintenance of the hangers.

[0006] Preferably, the top of the bridge body is provided with a bridge deck, and the bridge body is provided with a mesh reinforcing rib, and multiple sets of longitudinal reinforcing strips are evenly provided on the mesh reinforcing rib, so that the bridge body can be subjected to more uniform force through the mesh reinforcing rib and reinforcing strip, thereby enhancing the load-bearing capacity and stability of the bridge body.

[0007] Preferably, the middle section of the bidirectional lead screw is set as an optical axis section, and a second gear is provided at the middle position of the optical axis section of the bidirectional lead screw, so that the second gear on the optical axis section of the bidirectional lead screw can rotate, thereby driving the bidirectional lead screw to rotate.

[0008] Preferably, a motor cover is provided at the bottom of the bridge body corresponding to one side of the gear two, and the motor two is provided inside the motor cover two, so that the motor cover two protects the motor two and prevents it from being directly exposed to the outside.

The output end of each motor extends into the support block and is connected to the rotating shaft through bearings and couplings, so that the motor cover protects the motor and drives the rotating shaft connected to it to rotate.

[0012] Preferably, the bridge bodies are connected by connecting grooves and connecting plates, and the bridge bodies are connected by pouring concrete. This allows for preliminary splicing of adjacent bridge bodies through the connection grooves and connecting plates, and a stable connection is achieved by pouring concrete, resulting in a better connection effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The lower-bearing tie-rod arch bridge approach bridge structure, through the motor two driving the gear three on its shaft to rotate, causes the gear three to drive the gear two meshing with it to rotate, causing the gear two to drive the double-sided lead screw to rotate, causing the double-sided lead screw to drive the threaded blocks at both ends to move in opposite directions, causing the threaded blocks to drive the reinforcing rods on both sides to move and insert into the fixed groove, which can strengthen the connection effect between the bridge bodies and make the entire structure more stable.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-5 The present invention provides an embodiment of a tie-arch bridge approach structure, comprising a bridge body 1 and support blocks 2. Multiple sets of support blocks 2 are evenly provided on both sides of the top of the bridge body 1, and a hanger 3 is provided in the middle of the top of each support block 2, and an arch rib 4 is provided between the hangers 3.

[0022] When in use, the bridge body 1 can be supported and fixed by the support block 2 and the hanger 3. The arch rib 4 set between the hangers 3 can further improve the structural strength and stability of the bridge body 1. The setting of the arch rib 4 makes the load-bearing capacity of the bridge body 1 stronger and can effectively distribute the pressure of the bridge surface 7.

[0023] A connecting groove is provided in the middle of one end of the bridge body 1, and a connecting plate 15 is provided in the middle of the other end of the bridge body 1. A screw groove 17 is provided in the middle of the connecting plate 15, and a bidirectional screw 18 is provided in the middle of the screw groove 17. Both ends of the bidirectional screw 18 are connected to threaded blocks 19 by threads. Both sides of the threaded blocks 19 are provided with reinforcing rods 16. The connecting plate 15 and the bridge body 1 corresponding to the reinforcing rods 16 are provided with fixing grooves. The middle section of the bidirectional screw 18 is set as an optical shaft section, and a gear 22 is provided in the middle of the optical shaft section of the bidirectional screw 18. A motor cover 20 is provided at the bottom of the bridge body 1 on one side of the gear 22, and a motor 21 is provided in the motor cover 20. The output end of the motor 21 extends through a bearing to a gear 3 23 in the screw groove 17, and the gear 3 23 meshes with the gear 2 22.

[0024] When in use, the motor 21 can be started to drive the gear 3 23 on its shaft to rotate, which in turn drives the gear 22 meshing with it to rotate, which in turn drives the double-acting screw 18 to rotate, which in turn drives the threaded blocks 19 at both ends of the double-acting screw 18 to move in opposite directions, which in turn drives the reinforcing rods 16 on both sides to move and insert into the fixing groove, which can strengthen the connection between the bridge bodies 1 and make the whole structure more stable.

[0025] The support block 2 has rotating grooves on both sides, and the support block 2 has parallel rotating shafts 13 on both sides in the middle. The rotating shafts 13 have rotating blocks 14 in the middle, and the rotating blocks 14 have connecting blocks 12 on the side near the rotating groove. The connecting blocks 12 have limiting plates 5 through the rotating groove on the other side. The rotating shafts 13 have gears 6 at one end, and the gears 6 on the rotating shafts 13 mesh with each other. The support block 2 has a motor cover 10 at one end corresponding to the rotating shaft 13 on one side, and a motor 11 is installed inside the motor cover 10. The output end of the motor 11 extends into the support block 2 and is connected to the rotating shaft 13 through bearings and couplings.

[0026] In use, the motor 11 drives the rotating shaft 13 connected to it to rotate, causing the gear 6 at the other end of the rotating shaft 13 to rotate. This causes the gears 6 in the same group of support blocks 2 to mesh and rotate, which in turn drives the rotating shaft 13 to rotate. The rotating shaft 13 then drives the rotating block 14 in the middle to rotate, and the rotating block 14 drives the limiting plate 5 to rotate in the rotating groove through the connecting block 12. The limiting plate 5 limits the two sides of the hanger 3, which can limit the hanger 3 between the support blocks 2 to prevent it from shaking or shifting. This can enhance the stability and safety of the structure, and the hanger 3 can also be separated for maintenance.

[0027] The top of the bridge body 1 is provided with a bridge deck 7, and the bridge body 1 is provided with a mesh reinforcing rib 8, and multiple sets of longitudinal reinforcing strips 9 are evenly provided on the mesh reinforcing rib 8.

[0028] In use, the bridge body 1 is reinforced by multiple sets of longitudinal reinforcing strips 9 on the mesh reinforcing ribs 8, which enhances the overall strength and stability of the bridge body 1. The design of the mesh reinforcing ribs 8 can disperse the load borne by the bridge deck 7, making it more evenly distributed, effectively reducing the deformation or damage to the bridge body 1 caused by uneven stress. At the same time, the setting of multiple sets of longitudinal reinforcing strips 9 can further enhance the reinforcement effect of the mesh reinforcing ribs 8 and improve the load-bearing capacity of the bridge body 1.

[0029] The bridge bodies 1 are connected to the connecting plate 15 by connecting grooves, and the bridge bodies 1 are connected by pouring concrete.

[0030] In use, align the connecting grooves of two adjacent bridge bodies 1 with the connecting plate 15 and insert them. Then pour concrete into the gap between the connecting grooves and the connecting plate 15. After the concrete has solidified, the two adjacent bridge bodies 1 can be firmly connected together to form an integral structure, making the connection more convenient and improving the connection strength.

[0031] In this embodiment, after aligning the connecting grooves of two adjacent bridge bodies 1 with the connecting plate 15 and inserting them, the motor 21 can be started to drive the gear 3 23 on its shaft to rotate. The gear 3 23 drives the gear 22 meshing with it to rotate, which in turn drives the bidirectional lead screw 18 to rotate. This causes the threaded blocks 19 at both ends of the bidirectional lead screw 18 to move in opposite directions, and the threaded blocks 19 drive the reinforcing rods 16 on both sides to move and insert into the fixing groove. This strengthens the connection between the bridge bodies 1 and makes the entire structure more stable. After the bridge bodies 1 are assembled, concrete can be poured into the gap between the connecting groove and the connecting plate 15. After the concrete solidifies, the two adjacent bridge bodies 1 can be firmly connected together to form an integral structure, making the connection more convenient and improving the connection strength. Then, the hanger 3 and the arch rib 4 are assembled and connected, allowing the bridge body 1 to be supported and fixed by the support block 2 and the hanger 3. The arch rib 4 set between the hangers 3 can further improve the structural strength and stability of the bridge body 1. The setting of the arch rib 4 makes the load-bearing capacity of the bridge body 1 stronger and can effectively distribute the load. The pressure on surface 7 allows motor 11 to drive the rotating shaft 13 connected to it to rotate, causing gear 6 at the other end of the rotating shaft 13 to rotate. This causes gears 6 in the same support block 2 to mesh and rotate, which in turn drives the rotating shaft 13 to rotate. The rotating shaft 13 then drives the middle rotating block 14 to rotate, causing the rotating block 14 to rotate through the connecting block 12. The rotating block 14 then drives the limiting plate 5 to rotate in the rotating groove, thus limiting the two sides of the lifting rod 3. This limits the lifting rod 3 between the support blocks 2, preventing it from shaking or shifting, and increasing its stability. The structural stability and safety can be enhanced by separating the hangers 3 for maintenance. During use, the bridge body 1 can be reinforced by multiple sets of longitudinal reinforcing strips 9 on the mesh reinforcing ribs 8, thereby enhancing the overall strength and stability of the bridge body 1. The design of the mesh reinforcing ribs 8 can distribute the load borne by the bridge deck 7 more evenly, effectively reducing the deformation or damage to the bridge body 1 caused by uneven stress. At the same time, the setting of multiple sets of longitudinal reinforcing strips 9 can further enhance the reinforcement effect of the mesh reinforcing ribs 8 and improve the load-bearing capacity of the bridge body 1.
