[0002] With rapid urban development, roads and bridges develop cracks over time due to environmental erosion, natural aging of materials, increased vehicle loads, and the presence of overloaded vehicles. These cracks significantly impact the safety of roads and bridges during normal use. Failure to repair and maintain them promptly will exacerbate damage to road surfaces and bridge decks, reducing their safety factor. Therefore, it is necessary to reinforce roads and bridges.
[0003] Existing road and bridge crack reinforcement equipment only fills the cracks with a reinforcing agent. Sometimes, the filling agent does not make firm contact with the inner wall of the crack, resulting in poor repair effect. In later use, the reinforcing agent is prone to detachment, causing the crack to crack again. Utility Model Content
[0004] The purpose of this utility model is to provide a road and bridge crack reinforcement device to solve the problems mentioned in the background art regarding the road and bridge crack reinforcement devices that only fill the cracks with reinforcement agent. Sometimes the filling reinforcement agent does not make firm contact with the inner wall of the crack, the filling reinforcement agent has a poor repair effect on the crack, and the reinforcement agent is prone to detachment during later use, causing the crack to crack again.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a crack reinforcement device for roads and bridges, including a crack filling component, a first positioning seat, a second positioning seat, and a positioning seat connecting component. The first positioning seat and the second positioning seat are fixed to the ground on both sides of the crack. The positioning seat connecting component connects the first positioning seat and the second positioning seat. The distance between the first positioning seat and the second positioning seat is reduced by the positioning seat connecting component. The crack filling component is slidably connected above the positioning seat connecting component. The crack filling component includes a crack filling material box. The crack filling material box includes a discharge pipe and a discharge head. The two ends of the discharge pipe are respectively connected to the discharge head and the crack filling material box.
[0006] Preferably, the positioning seat connection assembly includes a hydraulic actuator, a movable bracket, and a telescopic connector. The body of the hydraulic actuator is fixed to the side of the first positioning seat away from the second positioning seat. The output end of the hydraulic actuator is connected to the movable bracket. One end of the telescopic connector is connected to the movable bracket. The other end of the telescopic connector is connected to the first positioning seat. The telescopic connector has a telescopic and fixed structure.
[0007] Preferably, the telescopic connector is provided in two sets, which are respectively located at both ends of the movable bracket.
[0008] Preferably, the telescopic connector includes a main rod, a secondary rod, a limiting member, and a rotating fixing member. One end of the main rod is hinged to the movable bracket, and the other end is slidably connected to the secondary rod. A limiting member is provided at the end of the secondary rod away from the main rod, and the secondary rod and the main rod are fixed together by the rotating fixing member.
[0009] Preferably, when the first positioning seat and the second positioning seat are in the same position, the limiting member rotates into the limiting groove of the first positioning seat.
[0010] Preferably, the joint repair assembly further includes a discharge head bracket, which is installed on the side of the joint repair material box near the first positioning seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention utilizes a positioning seat connecting assembly. When connecting a pre-fixed first and second positioning seat using this assembly, the length of the assembly is adjusted and fixed according to the distance between the two seats. When the hydraulic actuator drives the movable bracket to move away from the second positioning seat, the limiting member at one end of the telescopic connector pulls the first positioning seat. Under the action of the hydraulic actuator, the first and second positioning seats move closer together, simultaneously generating tension in the surrounding ground. This causes the ground on both sides of the crack to compress towards the crack. The road surface has a certain elasticity, which allows for a slight convergence of the crack, increasing the adhesion area between the reinforcing agent and the crack wall. This results in better filling of the reinforcing agent and, during the compression process, increases the adhesion between the reinforcing agent and the crack wall, leading to better crack repair. After solidification, the crack reinforcement is complete, and the device can be disassembled. At the same time, after the device is removed, the pressure applied to the crack is reduced, and the crack will open slightly. At this time, the reinforcing agent, which has a certain elasticity after solidification, will increase the tension on the inner wall of the surrounding crack, thus making the crack repair more durable and stable, and less likely to crack again.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] One embodiment provided by this utility model: as follows Figure 1 As shown, a crack reinforcement device for roads and bridges includes a first positioning seat 1, a second positioning seat 2, a fixing connector 3, a positioning seat connecting assembly 4, and a crack filling assembly 5.
[0023] like Figure 1As shown, the first positioning seat 1 and the second positioning seat 2 are fixed to the ground on both sides of the crack by a fixing connector 3. First, the first positioning seat 1 is fixed to one side of the crack to be reinforced, and then the second positioning seat 2 is placed on the other side of the crack to be reinforced, parallel to and corresponding to the first positioning seat 1. The corresponding positions of the first positioning seat 1 and the second positioning seat 2 facilitate the connection of the other end of the positioning seat connecting assembly 4 on the first positioning seat 1 to the limiting area of the second positioning seat 2. When fixing the first positioning seat 1 and the second positioning seat 2 to the ground, the fixing connector 3 is used to install and fix them at the corresponding opening position on the ground to assist in the reinforcement of the ground crack. The edges of the round holes made by tools on the ground are flat. After the reinforcement is completed, the inside of the openings is filled with a reinforcing agent to prevent cracks from forming at the openings.
[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the seam repair assembly 5 is slidably connected above the positioning seat connecting assembly 4. The seam repair assembly 5 includes a movable seat 51, a seam repair material box 52, and a material outlet bracket 53. The bottom of the seam repair material box 52 is mounted on the movable seat 51, and the movable seat 51 is slidably connected to the second positioning seat 2. A pulley 511 is provided at the bottom of the movable seat 51, and a sliding groove 21 is provided above the second positioning seat 2, with the pulley 511 located inside the sliding groove 21. The seam repair material box 52 includes a material outlet pipe 521 and a material outlet 522, with the two ends of the material outlet pipe 521 connected to the material outlet 522 and the seam repair material box 52, respectively. The discharge head bracket 53 is installed on the side of the joint filling material box 52 near the first positioning seat 1. The discharge head bracket 53 includes a connecting frame 531, a discharge head limiting seat 532, and a joint filling component moving handle 533. One end of the discharge head limiting seat 532 is hinged to the connecting frame 531, and the other end is fixedly connected to the joint filling component moving handle 533. The discharge head 522 is inserted into the discharge head limiting seat 532 from top to bottom.
[0025] Workers can hold the crack filling component and move the handle 533 to a position parallel to the second positioning seat 2. Along the crack direction, the discharge head 522 is aligned with the crack position to fill the reinforcement agent. When the crack is not completely straight, the handle 533 can be moved in a direction perpendicular to the second positioning seat 2 while moving it in a parallel direction. This allows the discharge trajectory of the discharge head 522 to match the direction of the crack, thereby improving the accuracy of the reinforcement agent filling the crack.
[0026] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the positioning seat connecting assembly 4 connects the first positioning seat 1 and the second positioning seat 2, and the distance between the first positioning seat 1 and the second positioning seat 2 is reduced through the positioning seat connecting assembly 4. The positioning seat connecting assembly 4 includes a hydraulic device 41, a movable bracket 42, and a telescopic connector 43. The body of the hydraulic device 41 is fixed to the side of the first positioning seat 1 away from the second positioning seat 2. The output end of the hydraulic device 41 is connected to the movable bracket 42. One end of the telescopic connector 43 is connected to the movable bracket 42, and the other end of the telescopic connector 43 is connected to the first positioning seat 1. The telescopic connector 43 is a telescopic and fixed structure. The telescopic connector 43 includes a main rod 431, a secondary rod 432, a limiting member 433, and a rotating fixing member 434. One end of the main rod 431 is hinged to the movable bracket 42, and the other end is slidably connected to the secondary rod 432. The limiting member 433 is provided at the end of the secondary rod 432 away from the main rod 431. The secondary rod 432 and the main rod 431 are fixed together by the rotating fixing member 434.
[0027] Before the reinforcing agent solidifies after filling, when connecting the fixed first positioning seat 1 and second positioning seat 2 using the positioning seat connecting assembly 4, first rotate the telescopic connecting piece 43. Adjust the position of the auxiliary rod 432 relative to the main rod 431 according to the distance between the first positioning seat 1 and the second positioning seat 2, so that the limiting piece 433 falls exactly into the limiting groove 11 of the first positioning seat 1. The inner side of the rotating fixing piece 434 passes through the main rod 431 and abuts against the auxiliary rod 432 inside the main rod 431. Tightening the rotating fixing piece 434 fixes the auxiliary rod 432 relative to the main rod 431, keeping the length of the telescopic connecting piece 43 fixed. At this time, the distance between the first positioning seat 1 and the second positioning seat 2 remains unchanged. When the hydraulic actuator 41 drives the movable support 42 to move away from the second positioning seat 2, the limiting member 433 at one end of the telescopic connector 43 pulls the first positioning seat 1. Under the action of the hydraulic actuator 41, the first positioning seat 1 and the second positioning seat 2 move closer together, simultaneously generating tension in the surrounding ground. This causes the ground on both sides of the crack to compress towards the crack. The road surface has a certain elasticity, which allows for a slight convergence of the crack, thereby increasing the adhesion area between the reinforcing agent and the inner wall of the crack. The reinforcing agent fills well, and the compression during the solidification process increases the adhesion between the reinforcing agent and the inner wall of the crack, resulting in a good crack repair effect. After solidification, the crack reinforcement is complete, and the device can be disassembled. Disassembling the device reduces the compressive force applied to the crack, causing it to open slightly. This allows the solidified, elastic reinforcing agent to increase the tension on the surrounding inner wall of the crack, making the crack repair more durable and stable, and less prone to re-cracking.
[0028] The limiting groove 11 has a T-shaped structure. The inner diameter of the vertical part of the T-shape of the limiting groove 11 is larger than the outer diameter of the auxiliary rod 432 but smaller than the outer diameter of the limiting member 433. The inner diameter of the horizontal part of the T-shape of the limiting groove 11 is larger than the outer diameter of the limiting member 433. There are gaps between the periphery of the limiting member 433 and the auxiliary rod 432 and the limiting groove 11. Therefore, when the positions of the first positioning seat 1 and the second positioning seat 2 are not corresponding or not completely parallel, the gaps can accommodate a certain range of errors, ensuring that the limiting member 433 can accurately fall into the limiting groove 11 without affecting the normal operation of the device.
[0029] Multiple sets of hydraulic actuators 41 are arranged between the first positioning seat 1 and the movable support 42, and the multiple sets of hydraulic actuators 41 are symmetrically distributed about the first positioning seat 1. Two sets of telescopic connectors 43 are provided, respectively located at both ends of the movable support 42. When the first positioning seat 1 and the second positioning seat 2 move relative to each other, the distribution of the hydraulic actuators 41 and the telescopic connectors 43 can ensure that the first positioning seat 1 and the second positioning seat 2 are subjected to uniform force, and the distance between the first positioning seat 1 and the second positioning seat 2 changes stably, thereby making the compressive force on the crack stable and balanced.
[0030] The above are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
