Description

Technical Field

[0001] This utility model belongs to the technical field of curbstone repair, specifically relating to a curbstone slipform repair device. Background Technology

[0002] Curbstones, as an important component of urban roads and sidewalk edges, not only serve an aesthetic purpose but also bear important functions such as drainage, roadbed protection, and defining road boundaries. However, due to factors such as vehicle collisions, natural weathering, and climate change, curbstones are often damaged, such as cracking, breaking, or missing parts, affecting the city's aesthetics and pedestrian safety.

[0003] Traditional curbstone repair techniques mainly include replacing the curbstone with a new one or manual repair. Replacing the curbstone with a new one is costly, inefficient, and has a significant impact on traffic; manual repair, on the other hand, is prone to secondary damage due to uneven material filling and poor compaction, making it difficult to guarantee repair quality. In addition, these methods require high levels of physical exertion from construction workers and are difficult to adapt to complex and changing road conditions.

[0004] Existing curb slipform repair equipment is ill-suited for uneven road surfaces, prone to grout leakage, and easily leads to uneven mortar filling, affecting the strength and stability of the repaired curb. Furthermore, existing curb slipform repair equipment has poor obstacle-crossing performance, easily getting stuck in debris or potholes on the road surface, or exhibiting bouncing behavior, impacting repair quality and making it difficult to adapt to complex and changing road conditions.

[0005] In summary, existing curbstone repair equipment urgently needs an innovative technology to solve these problems and achieve efficient, stable, and economical curbstone repair. The multi-functional curbstone slipform repair equipment was designed and developed to address the limitations of traditional repair technologies. By integrating innovative technologies such as automated material handling, molding technology, adaptive bonding, and obstacle-crossing capabilities, it aims to provide a highly efficient, stable, cost-effective, and adaptable curbstone repair solution.

[0025] 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.

[0026] This utility model provides, for example Figures 1-5 The illustrated curbstone slipform repair equipment includes a support frame 1. Four movable wheels 101 are rolled at the four corners of the lower end of the support frame 1. A diesel generator 4 is installed on the rear side of the upper end of the support frame 1. A hydraulic adjustment frame 2 is mounted on the support frame 1. The hydraulic adjustment frame 2 includes a limiting frame 201, with a limiting rod 202 inserted inside the limiting frame 201. The upper end of a hydraulic rod 203 is connected to the limiting frame 201, and the lower end of the hydraulic rod 203 is connected to the limiting rod 202. Two hydraulic adjustment frames 2 are provided, located on the front and rear sides of the support frame 1 respectively. Each adjustment frame 2 has a pulley 204 at its lower end. A pressure regulating machine 3 is mounted on the hydraulic adjustment frame 2, and both hydraulic adjustment frames 2 are connected to the two pressure regulating machines 3 via hydraulic pipes for adjusting the height of the hydraulic adjustment frame 2.

[0027] The upper front side of the support frame 1 is provided with a feeding hopper 5, and the end of the feeding hopper 5 is connected to a guide hopper 6. The guide hopper 6 is connected to the screw extruder 8 through a connection port 7. The screw extruder 8 is driven by a diesel generator 4 and is used to continuously extrude the material into the forming stop formed by the forming upper stop 9 and the forming side stop 10. The end of the discharge port of the screw extruder 8 is provided with a forming stop.

[0028] The top of the upper forming stop 9 is provided with an adjustment groove 11, which is located on the left and right sides of the top of the upper forming stop 9. The adjustment groove 11 extends vertically through the upper forming stop 9. A side forming stop 10 is slidably inserted into the adjustment groove 11. The top plate 1002 is set horizontally. Two side plates 1001 are connected to the bottom of the top plate 1002. The two side plates 1001 are respectively connected to the left and right sides of the top plate 1002. The side forming stop 10 is shaped like a "Z". The left and right side plates 1001 are respectively inserted into the adjustment grooves 11 on the left and right sides. The top plate 1002 is connected to the left and right side plates 1001. The side plates 1001 are slidably connected to the adjustment grooves 11. The lower side of the top plate 1002 is attached to the top of the upper forming stop 9. A side wing 901 is provided below the upper forming stop 9. The side wing 901 is vertically arranged on the left and right sides of the forming side stop 10. The side wing 901 is attached to the side opposite to the side plate 1001 and is used to limit the lateral deviation of the forming side stop 10.

[0029] The upper forming stop 9 is provided with a top surface bonding mechanism, which includes a limiting slide rod 12 and a bonding spring 13. The limiting slide rod 12 is located on the upper side of the upper forming stop 9. A baffle 1201 is provided on the top of the limiting slide rod 12. A through hole 1003 is provided on the top plate 1002. The limiting slide rod 12 passes through the through hole 1003. The bonding spring 13 is sleeved on the limiting slide rod 12 and is located between the baffle 1201 and the top plate 1002. The forming side stop 10 is elastically connected to the limiting slide rod 12 through the bonding spring 13. During the curbstone repair process, the lower sides of the forming side stop 10 can slide up and down inside the forming upper stop 9 through two adjusting grooves 11, and together with the forming upper stop 9, restrict the shape of the curbstone to be repaired. When the road surface is uneven, the forming side stop 10 can adjust its position relative to the road surface through the action of two contact springs 13, and can fit tightly with the road surface under the action of the two contact springs 13. This allows the repair equipment to adjust the contact position and contact force with the road surface by sliding the forming side stop 10 when repairing uneven road surfaces, so that the repair equipment can better adapt to the repair of uneven road surfaces, ensure that the high-strength polymer mortar does not leak out, ensure the internal pressure of the high-strength polymer mortar, and ensure the stability and strength of the repaired curbstone.

[0030] The lower ends of the left and right side plates 1001 are provided with road surface bonding mechanisms. The road surface bonding mechanism includes bonding blocks 14, which are arranged along the lower edge of the side plates 1001. Multiple support rollers 20 are provided at the lower end of the bonding blocks 14, and the lower ends of the support rollers 20 protrude from the lower end of the bonding blocks 14. The lower end of the forming side stop 10 contacts the road surface through the support rollers 20. The road surface bonding mechanism also includes adjustment sliding holes 15, which are provided through the bonding blocks 14. The multiple adjustment sliding holes 15 vertically penetrate the bonding blocks 14, and the interiors of the multiple adjustment sliding holes 15 are slidably connected. The device includes an adjustment slider 16 and multiple adjustment holes 15 with internal compression grooves 17. The compression grooves 17 are located on the inner walls of the front and rear ends of the adjustment holes 15. A limiting plate 18 is fixedly connected to the lower side of the adjustment slider 16, and the limiting plate 18 is slidably connected to the inside of the compression grooves 17 and engages with the front and rear compression grooves 17 respectively. A support spring 19 is provided at the upper end of the limiting plate 18, and the limiting plate 18 is elastically connected to the inside of the compression grooves 17 through the support spring 19. A support roller 20 is rotatably connected to the lower end of the adjustment slider 16 through a fixed shaft.

[0031] When the forming side stop 10 is in contact with and moves along the road surface, the forming side stop 10 can be in contact with and move along the road surface through multiple support rollers 20 set on both sides of the lower end. This can reduce the wear between the forming side stop 10 and the road surface, improve the service life of the forming side stop 10, and reduce the friction between the forming side stop 10 and the road surface, making it easier to push the repair equipment and reducing labor intensity. The multiple support rollers 20 can adjust their position with the forming side stop 10 by sliding the adjusting slider 16 inside the adjusting sliding hole 15, and the sliding position can be limited by the squeezing groove 17 and the limiting plate 18. At the same time, the forming side stop 10 can be supported by the support spring 19, so that the support rollers 20 can better overcome debris and potholes on the road surface, thereby improving the obstacle-crossing ability of the support rollers 20, and thus improving the obstacle-crossing ability of the forming side stop 10, preventing the repair equipment from being stuck by debris and potholes on the road surface, and improving the working stability of the repair equipment.

[0032] In use, the repair equipment is pushed to the curbstone that needs repair using the moving wheels. Since the hydraulic adjustment frame 2 consists of an external limiting frame, an internal hydraulic rod, and lower pulleys, and the hydraulic rod can control the support height of the pulleys via the pressure regulating machine 3, the height of the lower pulleys of the two hydraulic adjustment frames 2 can be adjusted using two pressure regulating machines 3 to ensure that the height of the upper forming stop 9 and the side forming stop 10 is exactly the same as the height of the curbstone. High-strength polymer mortar is poured into the feeding hopper 5, and the diesel engine 4 is started. The diesel engine 4 is connected to the screw rod inside the screw extruder 8 via a power wheel and belt, driving the screw rod to rotate. The high-strength polymer mortar inside the feeding hopper 5 is introduced into the screw extruder 8 through the guide hopper 6 and the connecting port 7, and pushed forward by the screw rod inside the screw extruder 8, thus extruding the high-strength polymer mortar from... The high-strength polymer mortar is pushed into the upper forming seat 9 and the side forming seat 10 through the opening at the front end of the screw extruder 8, and comes into contact with the damaged curbstone. After being compacted by the pushing and vibration of the screw, the high-strength polymer mortar is formed by the slipform through the upper forming seat 9 and the side forming seat 10. At the same time, the repair equipment is pushed backward, so that the high-strength polymer mortar is continuously formed by moving and vibrating under the action of the repair equipment. This gives the repaired curbstone high impact resistance and stability. Moreover, the height between the repaired curbstone and the road surface can be adjusted by the sliding of the side forming seat 10 inside the upper forming seat 9 to adapt to uneven road surfaces. This ensures that the high-strength polymer mortar does not leak from the lower end of the side forming seat 10, preventing waste of high-strength polymer mortar and saving repair costs. It also ensures the strength of the high-strength polymer mortar squeezed by the screw, improving the repair quality.
