Description

[0002] The current bridge reinforcing and supporting device is relatively simple and is more suitable for flat long and short bridges. However, there is still some difficulty in reinforcing or constructing a curved bridge. During the driving process of a vehicle on a curved bridge, there is usually some centrifugal force, which is prone to accidents. Therefore, the curved end bridge is usually inclined, that is, the height of the outer ring is higher than that of the inner ring, thereby increasing the friction between the vehicle and the ground during driving.

[0003] However, the beam of the end bridge is also inclined, and the conventional reinforcing and supporting device in the prior art is often difficult to perform well, especially when facing an indefinite bend angle, an indefinite bridge inclination angle, and an indefinite bridge width. The supporting and contacting effects of the bridge cannot be adaptively adjusted and matched. In order to further improve the supporting effect of the bridge, a bridge reinforcing system for municipal bridge engineering is proposed. SUMMARY

The support limb 22 is hinged to the output end of the telescopic rod 21 and is configured to reciprocate along a horizontal axis L2.

[0069] It can be understood that when the telescopic rod 21 rotates about the vertical axis L1, the support limb 22 rotates synchronously; when the telescopic rod 21 moves in the vertical direction, the support limb 22 moves synchronously; and the support limb 22 is also able to move independently of the telescopic rod 21 along the horizontal axis L2, i.e. away from or close to the telescopic rod 21.

[0070] Figure 5 is a top view of the municipal bridge reinforcing system provided by the embodiment, as shown in Figure 5 The base 1 is provided with a sliding table 14, Figure 6 is a schematic view of the internal structure of the sliding table 14.

[0071] As shown in Figure 5 and Figure 6 The adjusting device 2 further comprises a worm gear transmission assembly 23, a driven wheel 24, a power mechanism one 25 and a driving wheel 26.

[0072] The worm gear transmission assembly 23 is located inside the sliding table 14. The first end of the worm gear transmission assembly 23 is connected to the telescopic rod 21 to make the telescopic rod 21 rotate.

[0073] In the embodiment, the worm gear part of the worm gear transmission assembly 23 is fixedly connected with the bottom of the telescopic rod 21. When the worm gear part rotates, the telescopic rod 21 rotates synchronously. It can be understood that the center of rotation of the worm gear part is coaxial with the vertical axis L1.

[0074] The driven wheel 24 is coaxially connected to the second end of the worm gear transmission assembly 23.

[0075] In this embodiment, the driven wheel 24 is located outside the sliding table 14, one end of the worm part of the worm gear transmission assembly 23 is connected to the center of the driven wheel 24, the driven wheel 24 rotates to drive the worm part, the worm part meshes with the worm gear part to continue to drive the worm gear part and the telescopic rod 21 to rotate.

[0076] The output end of the power mechanism one 25 is connected to the driving wheel 26, the driving wheel 26 meshes with the driven wheel 24 to drive the driven wheel 24 to rotate, and finally realizes the rotation of the telescopic rod 21 according to the above description.

[0077] In this embodiment, two groups of telescopic rods 21 are connected on the sliding table 14, and the corresponding worm gear transmission assemblies 23 and driven wheels 24 are connected, on the other hand, the sliding table 14 is provided with a slidable power mechanism one 25, the driving wheel 26 can selectively mesh with one of the driven wheels 24 at the same time, and control the rotation of the corresponding telescopic rod 21.

[0078] In this embodiment, the two groups of gears 24 are located on the same side of the sliding table 14, the power mechanism one 25 moves linearly reciprocatingly, and the driving wheel 26 can mesh with the driven wheel 24 at both ends of its stroke.

[0079] Figure 7 is Figure 1 part of the schematic view, in combination with Figure 4 and Figure 7 , the telescopic rod 21 comprises a main rod body 210, a secondary rod body 211, a sliding sleeve 212, a power mechanism two 213, a connecting rod 214 and a sliding block 215.

[0080] The main rod body 210 is arranged in a vertical direction and can move up and down, the secondary rod body 211 is arranged along a horizontal axis L2, that is, the main rod body 210 and the secondary rod body 211 are at right angles.

[0081] The sliding sleeve 212 is slidably sleeved on the main rod body 210, and it can be understood that the sliding sleeve 212 can move in the vertical direction.

[0082] One end of the power mechanism two 213 is fixed to the main rod body 210, and the other end is connected to the sliding sleeve 212 to make it move up and down. One end of the connecting rod 214 is hinged to the sliding sleeve 212, and the other end is hinged to the support limb 22.

[0083] The sliding block 215 is slidably arranged on the secondary rod body 211, and the lower end of the support limb 22 is fixedly connected to the sliding block 215. In this embodiment, the secondary rod body 211 has a sliding groove with a half-enclosing structure, the sliding groove is open upward, and the sliding block 215 is supported on the secondary rod body 211.

[0084] It can be understood that when the power mechanism two 213 drives the sliding sleeve 212 to move up and down, the support limbs 22 and the sliding blocks 215 will be driven to move on the auxiliary rod body 211 due to the hinging effect of the connecting rods 214.

[0085] In this embodiment, the sliding sleeve 212 is a rectangular frame structure, and the main rod body 210 is a cuboid structure. The sliding sleeve 212 is fitted in the gap between the main rod body 210, and the sliding sleeve 212 can only move up and down on the main rod body 210 and cannot rotate.

[0086] In this embodiment, two support limbs 22 are arranged on each telescopic rod 21, and the two support limbs 22 are mirror image arranged about the main rod body 210.

[0087] Further, two support limbs 22 are provided in this embodiment, but only one power mechanism two 213 is provided, and two connecting rods 214 are hinged on the sliding sleeve 212, thereby simultaneously driving the two support limbs 22 to move. In other words, the rotating directions of the two support limbs 22 are opposite, that is, they move away from each other or towards each other at the same time.

[0088] Figure 8 is an exploded view of the fixing member 3, as shown in Figure 8 The fixing member 3 further includes a guide plate 31, which is arranged at the bottom of the support plate 30 in the vertical direction.

[0089] The support limb 22 is further connected with a guide block 27 which can move relative to the support limb 22 in the horizontal direction. In this embodiment, the guide block 27 is connected to the bottom of the support table 220 of the support limb 22, and the two are perpendicular to each other.

[0090] The guide plate 31 is inserted into the guide block 27 under the action of gravity, and the guide block 27 moves in the horizontal direction under the action of external force, simultaneously driving the guide plate 31 to move upward and out of the guide block 27, thereby driving the whole fixing member 3 to move upward. When the external force disappears, the guide plate 31 returns to the guide block 27 under the action of gravity, and the whole fixing member 3 moves downward.

[0091] In this embodiment, the bottom of the support table 220 is further connected with a power mechanism three 28 for driving the guide block 27. The fixed end of the power mechanism three 28 is connected to the support table 220, and the movable end of the power mechanism three 28 is connected to the guide block 27, so as to drive the guide block 27 to reciprocate.

[0092] Specifically, the guide block 27 is provided with a slot 270 for inserting the guide plate 31. The slot 270 and the guide plate 31 are configured to be tightly fitted in the circumferential direction, and the bottom of the guide plate 31 and the slot bottom surface of the slot 270 are fitted in the inclined surface. It can be understood that the guide block 27 and the guide plate 31 are only limited to relative movement in the vertical direction.

[0093] Further, the support plate 30 is hinged with a counterweight 32 at the bottom. The counterweight 32 is arranged so that the support plate 30 is always in a horizontal state, thereby reducing the damage and friction to the bottom of the bridge when the bridge is contacted.

[0094] The guide block 27 is provided with a clearance space 310 for avoiding the counterweight 32. In the embodiment, the guide block 27 is in a U-shaped structure.

[0095] Continuing to refer to Figure 8 The support plate 30 comprises a support plate body 301 and a roller 302 arranged at one side of the support plate body 301. The rotating roller 303 is used to reduce the friction between the support plate body 301 and the bridge when the support plate body 301 is contacted with the curved bridge, thereby avoiding secondary damage to the bridge.

[0096] The reinforcing system provided by the embodiment is capable of rotating around a vertical axis L1 and moving in a vertical direction, the support limb 22 is hinged at the output end of the telescopic rod 21 and is configured to move along a horizontal axis L2, so that the support limb 22 is capable of rotating around the vertical axis and moving in the height direction, and the support limb 22 is capable of moving around the horizontal axis, thereby further adjusting the height and horizontal distance of the support limb 22 relative to the telescopic rod 21, and the fixing member 3 is arranged on the support limb so as to realize the same position change as the support limb 22, and the fixing member 3 is capable of moving in the height direction, thereby adapting to bridges with different shapes, angles and heights.
