DETAILED DESCRIPTION

[0024] The embodiments of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the technical scheme of the utility model, but cannot be used to limit the protection scope of the utility model.

[0025] Example:

[0026] As Figures 1 to 5The utility model provides a grouting device for concrete pavement repair, which comprises a grouting pipe, a grouting cavity, a push rod, a piston block, a grouting assembly and a smoothing assembly.

[0027] The grouting assembly can ensure the stable grouting of cement slurry, and it is detachable on the grouting pipe. During the grouting operation, the grouting assembly can be adjusted according to different actual conditions, which can make the grouting more uniform and dense to fill the cracks and cavities, thereby enhancing the structural strength and integrity of the repaired pavement and increasing the practicability of the device.

[0028] The smoothing assembly is rotatably arranged in the mounting portion 104. During the smoothing operation, the operator can flexibly rotate the angle of the smoothing assembly as needed. When smoothing some irregular grouting areas, the smoothing plate 502 of the smoothing assembly can be better attached to the pavement surface by rotating the smoothing assembly, which can smooth along different directions and contours, reduce the dead angle of smoothing, improve the comprehensiveness and uniformity of smoothing, and make the surface of the repaired pavement more smooth. The smoothing assembly is installed on the outer side of the grouting pipe, so that the grouting and smoothing operation processes can be performed continuously without the need to change tools or move the device to other positions, saving time and labor costs and improving the efficiency of the entire concrete pavement repair work.

[0029] As shown in the drawings, the utility model provides a grouting device for concrete pavement repair, which comprises a grouting pipe, a grouting cavity, a push rod, a piston block, a grouting assembly and a smoothing assembly. Figures 1 to 2As shown, the outer side of the grouting pipe 1 is also provided with two sets of foldable booster rods 701; the end of the push rod 2 away from the grouting pipe 1 is also fixedly connected with a push plate 702. The two sets of foldable booster rods 701 are arranged on the outer side of the grouting pipe 1, and the operator can unfold the booster rods 701 when performing the grouting operation. In this way, when the push rod 2 is pushed to extrude the cement slurry for grouting, the hands can hold the booster rods 701, and the booster rods 701 are used as the fulcrum to make the force exertion process more convenient and stable, and the booster rods 701 can be used to exert sufficient pushing force more easily, thereby reducing the working intensity of the operator; at the same time, the foldable booster rods 701 can be folded up when not in use or when the device is stored, thereby reducing the overall occupied space of the device, facilitating carrying and storage, and improving the portability of the device. The push plate 702 fixedly connected to the end of the push rod 2 away from the grouting pipe 1 provides a larger contact surface for the operator, which can disperse the pressure exerted by the hands, avoid discomfort of the hands caused by excessive local pressure, and improve the comfort of the operation.

[0030] As shown in Figures 2 to 5 , the grouting assembly comprises a grouting head 201, and the end of the grouting pipe 1 away from the cover 3 is also provided with a grouting port 202. The end of the grouting head 201 corresponds to the grouting port 202 and is provided with an assembly groove 203, and the assembly groove 203 is sleeved on the grouting port 202. A rubber sealing ring 301 is arranged between the assembly groove 203 of the grouting head 201 and the grouting port 202. The grouting head 201 is sleeved on the grouting port 202 through the assembly groove 203, which makes the replacement operation of the grouting head 201 simple and convenient. For the repair of small cracks, a fine grouting head 201 is needed to accurately control the grouting amount and flow rate. For the repair of large-area cavities, a grouting head 201 with a larger flow rate may be needed. Through this replaceable performance, the user can quickly replace the appropriate grouting head 201 according to the actual situation, thereby improving the flexibility and adaptability of the device and meeting various repair needs. The rubber sealing ring 301 is arranged between the assembly groove 203 of the grouting head 201 and the grouting port 202, which can effectively prevent the cement slurry from leaking from the connection during the grouting process. The presence of the sealing ring 301 can ensure that the cement slurry is injected into the damaged part of the road surface through the grouting head 201, thereby ensuring the integrity and effectiveness of the grouting.

[0031] As shown in Figure 1 , Figure 2 and Figure 5As shown, the troweling assembly includes a connecting rod 401, one end of the connecting rod 401 is provided with a connecting part 402, the connecting rod 401 is rotatably arranged in the mounting part 104 through the connecting part 402; the other end of the connecting rod 401 is also provided with an assembly groove 501, and the assembly groove 501 is also replaceably provided with a troweling plate 502. The connecting part 402 on the connecting rod 401 is rotatably arranged in the mounting part 104, and the operator can adjust the direction and angle of troweling according to the actual situation and needs of the road surface during the troweling operation after the grouting is completed. This can make the troweling plate 502 on the connecting rod 401 better fit the road surface, so that the cement paste is evenly spread, so as to improve the quality and efficiency of troweling; at the same time, the connecting rod 401 is also detachable in the mounting part 104, and the operator can also detach the connecting rod 401 according to the actual use habit of the operator, and perform troweling operation in a handheld manner. This can increase the practicability and applicability of the device.

[0032] A stable and easy-to-operate connection is formed between the assembly groove 501 and the troweling plate 502. In actual use, according to the material properties, damage degree, repair requirements and environment of different concrete pavements, the original troweling plate 502 can be easily detached and replaced with a troweling plate 502 having different materials, different surface textures and different size specifications. Thus, the most ideal troweling effect can be achieved in various complex scenarios, the quality and efficiency of concrete pavement repair work are improved, and high flexibility and wide adaptability are achieved in actual application.

[0033] As shown in Figures 1 to 3 As shown, the outer surface of the grouting pipe 1 is also provided with two groups of clamping claws 601 opposite to each other, and the connecting rod 401 is provided with clamping grooves 602 corresponding to the two groups of clamping claws 601 on both sides. The two groups of clamping claws 601 are detachably arranged in the clamping grooves 602. The structure that the clamping claws 601 are detachably arranged in the clamping grooves 602 makes the installation and disassembly of the connecting rod 401 and the grouting pipe 1 simple. When the troweling assembly needs to be installed, the clamping claws 601 can be aligned with the clamping grooves 602 and pushed in gently to complete the connection. The operation is quick and efficient, and complex tools or complicated assembly steps are not needed. Similarly, when the troweling assembly needs to be maintained, the troweling plate 502 needs to be replaced, or the device needs to be stored, the clamping claws 601 can be easily pulled out of the clamping grooves 602 to separate the connecting rod 401 and the grouting pipe 1. This not only improves the work efficiency during construction, but also facilitates the individual maintenance and management of the parts of the device, prolonging the overall service life of the device.

[0034] The above merely describes the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
