Description

Technical Field

[0001] The utility model belongs to the technical field of bridge anti-falling, and more specifically, particularly relates to an anti-falling beam traction component. Background Art

[0002] Bridge structures have been repeatedly damaged to varying degrees due to their own insufficient seismic performance and improper selection of seismic measures, which not only adds some obstacles to earthquake relief, but also makes post-disaster reconstruction very difficult. In previous earthquakes, the blocks were damaged due to insufficient seismic resistance, and even lateral beam drop accidents occurred. Therefore, in the study of the damage mechanism of bridge earthquake disasters and the seismic design of bridge structures, it is necessary to set up corresponding structures to prevent bridges from falling off.

[0003] After searching, for example, a patent with announcement number CN211973070U discloses a beam-falling prevention block, which relates to the technical field of railway bridge construction and solves the technical problem that the existing block can only limit the beam body but cannot measure the displacement of the beam body relative to the normal position. The utility model includes a block top plate, and the block top plate is provided with small holes on all sides for easy installation. Both ends of the block top plate are provided with block bending steel plates perpendicular to the block top plate, and a block shear steel plate is provided between the block bending steel plates. The block shear steel plate is perpendicular to the block top plate and the block bending steel plate. T-shaped mounting grooves are provided in the block bending steel plate and the block shear steel plate, and a pressure buffer component is detachably provided in the T-shaped mounting groove through a connecting component. The pressure buffer component is detachably connected to the block shear steel plate and the block bending steel plate through a locking component. The utility model realizes the detection of beam displacement through the elastic deformation of the buffer spring in the pressure buffer component.

[0004] The anti-falling beam structure in the above patent still has the following shortcomings:

[0005] At present, in the construction of bridge lowering, the anti-falling of the bridge is mostly limited by setting blocks on both sides of the bridge. The limiting structures such as blocks belong to the rigid limiting method. When encountering an earthquake with slightly larger intensity, the limiting effect is low, and it can only limit the displacement on both sides of the bridge. When encountering a strong wind earthquake that causes the bridge to lift up and down, it cannot effectively buffer and limit the bridge, which has certain limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an anti-falling beam traction component to solve the problem proposed in the above background technology that in the construction of bridge lowering, the anti-falling position of the bridge is mostly achieved by setting blocks on both sides of the bridge. The blocking blocks and other limiting structures belong to the rigid limiting method. When encountering an earthquake with slightly greater intensity, the limiting effect is relatively low, and it can only limit the displacement on both sides of the bridge. When encountering the up and down lifting of the bridge caused by the strong wind earthquake, it is not possible to buffer and limit the bridge well, and has certain limitations.

[0007] The purpose and effect of the anti-falling beam traction assembly of the utility model are achieved by the following specific technical means:

[0008] A beam-fall prevention traction assembly comprises: a base plate; the base plate adopts a rectangular plate structure; a first damper is fixedly arranged in the middle of the top of the base plate; a top plate is fixedly connected to the top of the first damper, and the top plate adopts a rectangular plate structure; a connecting block with a rectangular block structure is fixedly arranged at the bottom of the top plate, and a circular groove structure is opened in the middle of the bottom of the connecting block, and the first damper is arranged on the inner side of the circular groove at the bottom of the connecting block; a group of limiting grooves are fixedly arranged on both sides of the bottom of the connecting block, and the limiting grooves adopt a rectangular groove structure; second dampers are fixedly arranged on the inner side of the limiting grooves; the outer ends of each group of second dampers are fixedly connected to a top block with a rectangular block structure.

[0009] Furthermore, the bottom of the base plate is fixedly provided with lower embedded steel bars in a rectangular array; a group of side plates are fixedly provided on both sides of the top of the base plate, and the side plates adopt an L-shaped plate structure; the top of the top plate is fixedly provided with upper embedded steel bars in a rectangular array; connecting rods are rotatably connected on the front and rear sides of the connecting block; a group of mounting plates of a rectangular plate structure are fixedly provided on the top of the connecting rods, and the mounting plates are fixedly connected to the beam body; by fixedly connecting the two groups of mounting plates to the beam body, the stability of the connection between the top plate and the bridge can be further increased.

[0010] Furthermore, a group of sliding rods are fixedly arranged on both sides of the bottom of the top plate, and the sliding rods adopt a cylindrical structure; a group of screw rods are rotatably arranged on the bottom of both sides of the top plate; a group of sliding blocks of rectangular plate structure are slidably arranged on the outer sides of the two groups of sliding rods, and a through-type screw hole structure is opened on one side of the top of the sliding block, and the sliding block and the screw rod are connected by threaded cooperation; the sliding block can be driven to move up and down along the sliding rod by rotating the screw rod, so that the distance between the sliding block and the side plate can be adjusted according to different situations, thereby achieving the purpose of adjusting the maximum movement range according to different situations.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the present application, when the bridge vibrates and displaces, when the amplitude of movement is small, the first damper can be used to limit the position and absorb the vibration. When a large degree of up and down displacement occurs, the slider and the side plate can be used to rigidly limit the position, thereby achieving a better limiting effect on the up and down movement of the bridge. The cooperation of the two limiting effects can greatly improve the limiting effect of the bridge, thereby achieving a better limiting effect while minimizing damage to the beam body, which is beneficial to extending the service life of the beam body.

[0013] When movement occurs in the left and right directions, the vibration is absorbed and limited by each group of second dampers, and rigid limitation is performed through the side panels to prevent the bridge from moving too much in the left and right directions, thereby achieving the purpose of limiting the left and right directions of the bridge. The movement of the bridge in all directions can be limited, thereby improving the limiting effect of the device and meeting different usage needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The specific usage and function of this embodiment are as follows:

[0027] When movement occurs in the left and right directions, the two groups of limit grooves 205 and each group of second dampers 206 on both sides will be synchronously driven to displace, thereby driving the top block 207 to contact the inner wall of a group of side panels 102 on the corresponding side, and absorbing and limiting the vibration through each group of second dampers 206, while rigidly limiting the side panels 102 to avoid excessive left and right movement of the bridge, thereby achieving the purpose of limiting the left and right directions of the bridge.

[0028] Embodiment 2:

[0029] Based on Example 1, as shown in the attached Figure 1 To Attachment Figure 6 As shown:

[0030] Among them, the bottom of the bottom plate 1 is fixedly provided with lower embedded steel bars 101 in a rectangular array; a group of side panels 102 are fixedly provided on both sides of the top of the bottom plate 1, and the side panels 102 adopt an L-shaped plate structure; the top of the top plate 2 is fixedly provided with upper embedded steel bars 201 in a rectangular array; the front and rear sides of the connecting block 202 are rotatably connected with connecting rods 203; the top of the connecting rod 203 is fixedly provided with a group of mounting plates 204 of a rectangular plate structure, and the mounting plates 204 are fixedly connected to the beam body.

[0031] Among them, a group of sliding rods 208 are fixedly arranged on both sides of the bottom of the top plate 2, and the sliding rods 208 adopt a cylindrical structure; a group of screw rods 209 are rotatably arranged on the bottom of both sides of the top plate 2; a group of sliding blocks 210 with a rectangular plate structure are slidably arranged on the outer sides of the two groups of sliding rods 208, and a through-type screw hole structure is opened on one side of the top of the sliding block 210, and the sliding block 210 is connected with the screw rod 209 through threaded matching.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In the utility model, during construction, the lower embedded steel bar 101 is embedded in the pier to fix the bottom plate 1 with the pier, and the upper embedded steel bar 201 is embedded in the bridge to fix the top plate 2 with the bridge, and then the top of the first damper 103 is fixedly connected with the connecting block 202, and the two sets of side plates 102 are respectively welded to the top of the two sides of the bottom plate 1, and then the height of the two sets of sliders 210 is adjusted according to the maximum displacement variable, so that the distance between the slider 210 and the side plate 102 can be lower than the maximum displacement. When the bridge encounters vibration in the up and down directions, the first damper 103 is used to buffer and limit the movement between the bottom plate 1 and the top plate 2, and partially absorb the vibration transmitted from the bridge. If the vibration amplitude in the up and down directions is large, the two sets of sliders 210 will be driven to move synchronously. During the up and down movement of the two sets of sliders 210, if the vibration amplitude continues to increase, the two sets of sliders 210 will contact the two sets of side plates 102 respectively, and through The two groups of side plates 102 have a limiting effect on the two groups of sliders 210, and thus have a certain rigid limiting effect on the up and down movement range of the top plate 2 and the bridge, so as to avoid the phenomenon that the up and down movement distance of the bridge continues to move and displace after exceeding the maximum safe distance, and effectively limit the up and down movement of the bridge. When the movement range is small, the first damper 103 can be used to limit and absorb the vibration. When a large degree of up and down displacement occurs, the slider 210 and the side plate 102 can be used to rigidly limit the up and down movement of the bridge, so as to have a better limiting effect. At the same time, the slider 210 can be driven to move up and down along the slide rod 208 by rotating the screw 209, so as to adjust the distance between the slider 210 and the side plate 102 according to different situations, so as to achieve the purpose of adjusting the maximum movement range according to different situations. By fixedly connecting the two groups of mounting plates 204 to the beam body, the stability of the connection between the top plate 2 and the bridge can be further increased.
