[0029] Example 1: As Figures 1-3 As shown, this utility model provides a road crack grouting pipe assembly, including: a shell 10, a first pipe body 20, a second pipe body 30, and a driving device 40. The shell 10 is provided with a receiving cavity 11, which is suitable for containing repair agent. The first pipe body 20 is rotatably connected to the bottom of the shell 10 and is provided with a grouting channel, which communicates with the receiving cavity 11. The outer peripheral wall of the first pipe body 20 is provided with a spiral crack widening blade. The second pipe body 30 is rotatably disposed in the receiving cavity 11 and is provided with a stirring part 31 on its outer peripheral wall. The driving device 40 has a rotatable driving rod 41, which can selectively drive the first pipe body 20 or the second pipe body 30 to rotate.

[0030] In some embodiments, the housing 10 has a receiving cavity 11 inside, which is used to store repair agent. The first tube 20 is rotatably connected to the bottom of the housing 10. The first tube 20 is provided with a grouting channel inside, which communicates with the receiving cavity 11 inside the housing 10. The outer peripheral wall of the first tube 20 is provided with a spiral expansion blade, which is used to rotate when inserted into the crack to enlarge and clean the crack, creating conditions for subsequent injection of repair agent. The second tube 30 is rotatably installed in the receiving cavity 11. The outer peripheral wall of the second tube 30 is provided with a stirring part 31. By rotating the second tube 30, the repair agent in the receiving cavity 11 can be stirred to prevent the repair agent from settling or solidifying while waiting for use. The driving device 40 is equipped with a rotatable driving rod 41, which can selectively drive the first tube 20 or the second tube 30 to rotate.

[0031] Understandably, when the drive rod 41 engages with the first tube 20, the rotation of the drive rod 41 will cause the first tube 20 to rotate, and the spiral expansion blade on the outer wall of the first tube 20 will rotate accordingly, thereby expanding and cleaning the road cracks; when the drive rod 41 engages with the second tube 30, the rotation of the drive rod 41 will cause the second tube 30 to rotate, and the stirring part 31 on the outer wall of the second tube 30 will rotate accordingly, stirring the repair agent in the receiving cavity 11, preventing the repair agent from solidifying or settling due to prolonged standing.

[0032] According to the road crack grouting pipe assembly, the spiral expansion joint blade is arranged on the outer peripheral wall of the first pipe body 20, the first pipe body 20 is rotated to be suitable for expanding and cleaning the road crack, the integration of the grouting device and the expansion joint drill is realized, the transportation of the road repair tool is reduced, compared with the grouting device and the expansion joint drill, the grouting pipe assembly has small volume and low production cost, and the driving device 40 can selectively drive the first pipe body 20 or the second pipe body 30 to rotate, so that the road crack is expanded and cleaned or the repair agent in the stirring containing cavity 11 is stirred, the number of the driving device 40 is reduced, and therefore the volume and the production cost of the grouting pipe assembly are further reduced.

[0033] In the embodiment, the first pipe body 20 and the second pipe body 30 are arranged in the height direction and are spaced apart, the driving rod 41 is arranged between the first pipe body 20 and the second pipe body 30, and the driving rod 41 is selectively movable in the height direction and has a first position and a second position.

[0034] In some embodiments, the first pipe body 20 and the second pipe body 30 are arranged in the height direction and are spaced apart, that is, the relative positions of the first pipe body 20 and the second pipe body 30 in the vertical direction are fixed, and the first pipe body 20 and the second pipe body 30 are a certain distance apart, the driving rod 41 is located between the first pipe body 20 and the second pipe body 30, and the driving rod 41 can move in the height direction, that is, the driving rod 41 can move up and down along the vertical direction, so as to change the relative positions of the driving rod 41 and the first pipe body 20 and the second pipe body 30, in the first position, the driving rod 41 cooperates with the first pipe body 20, so that the rotation of the driving rod 41 can drive the rotation of the first pipe body 20, and in the second position, the driving rod 41 cooperates with the second pipe body 30, so that the rotation of the driving rod 41 can drive the rotation of the second pipe body 30.

[0035] It can be understood that when the expansion joint operation is needed, the driving rod 41 is adjusted to the first position, at this time the rotation of the driving rod 41 will drive the rotation of the spiral expansion joint blade on the first pipe body 20, so as to clean and expand the road crack; when the repair agent needs to be stirred, the driving rod 41 is adjusted to the second position, at this time the rotation of the driving rod 41 drives the rotation of the stirring part 31 on the second pipe body 30, so as to prevent the repair agent from precipitating or distributing unevenly during waiting for use.

[0036] It can be understood that one driving device 40 can support both functions of expansion and stirring at the same time, which simplifies the structure of the grouting pipe assembly, and the functions can be switched by simply adjusting the position of the driving rod 41 without the need to change tools or reconfigure the equipment, and at the same time, through continuous stirring, it ensures that the repair agent remains uniform before use, avoids the problem of sedimentation of the repair agent in the accommodating cavity 11, and thus improves the repair effect on the road cracks.

[0037] In this embodiment, on the basis of embodiment two, the inner circumferential wall of the grouting channel is provided with a first limiting block 21, the second pipe body 30 is provided with a connecting channel, the inner circumferential wall of the connecting channel is provided with a second limiting block 32, the free end of the driving rod 41 passes through the connecting channel and is located between the first pipe body 20 and the second pipe body 30, the free end of the driving rod 41 is provided with a matching block 411, and the grouting pipe assembly further comprises: a lifting assembly adapted to drive the driving device 40 to rise or fall, and the driving rod 41 rises or falls to enable the matching block 411 to cooperate with the first limiting block 21 or the second limiting block 32.

[0038] In some embodiments, the lifting assembly can drive the driving device 40 to rise or fall, so as to realize the rising or falling of the driving rod 41, and thus the matching block 411 on the driving rod 41 can be in contact with the first limiting block 21 or the second limiting block 32. When the lifting assembly drives the driving device 40 to fall and the matching block 411 is located at the first position, the matching block 411 is in contact with the first limiting block 21, and the rotation of the driving rod 41 drives the first pipe body 20, thereby realizing the expansion operation; when the lifting assembly drives the driving device 40 to rise and the matching block 411 is located at the second position, the matching block 411 is in contact with the second limiting block 32, and the rotation of the driving rod 41 drives the second pipe body 30, thereby realizing the stirring of the repair agent.

[0039] It can be understood that, through the cooperation of the matching block 411 and the first limiting block 21 or the second limiting block 32, it is ensured that the driving rod 41 can be accurately and reliably connected with the target pipe body to be driven, the operation precision of the grouting pipe assembly is improved, and the driving rod 41 selectively drives the first pipe body 20 or the second pipe body 30 in different working states, thereby enhancing the functionality and flexibility of the grouting pipe assembly, so that the grouting pipe assembly can be easily switched between expansion and stirring.

[0040] According to some embodiments of the present application, the lifting assembly comprises: a lifting plate 51, the lifting plate 51 is movably connected with the shell 10, the lifting plate 51 is fixedly connected with the driving device 40, and the lifting plate 51 moves to drive the driving device 40 to rise or fall.

[0041] In some embodiments, the lifting plate 51 and the shell 10 are movably connected, allowing the lifting plate 51 to move linearly in the vertical direction relative to the shell 10, and the lifting plate 51 and the driving device 40 are fixedly connected, so that any movement of the lifting plate 51 in the vertical direction will drive the driving device 40 to move synchronously. Thus, when the lifting plate 51 moves upward, the lifting plate 51 will drive the driving device 40 to rise; conversely, when the lifting plate 51 moves downward, the driving device 40 will also descend.

[0042] According to some embodiments of the present application, the lifting assembly further comprises: a first lifting motor, the first lifting motor is connected with the shell 10, and a first output shaft of the first lifting motor is connected with the lifting plate 51.

[0043] In some embodiments, the first lifting motor is connected with the lifting plate 51 through its own output shaft, and the first lifting motor can control the output shaft to move towards or away from itself in the height direction when working, thereby driving the lifting plate 51 to move in the height direction.

[0044] It can be understood that after the first lifting motor is introduced, the lifting action of the lifting plate 51 can be automatically completed by the first lifting motor, and is no longer dependent on manual or other non-electrically driven ways, thereby improving the automation level of the grouting pipe assembly. Moreover, the use of the first lifting motor makes the lifting of the lifting plate 51 more relaxed and fast, reduces the complexity and labor intensity of manual operation. Of course, the first lifting motor drive can realize more precise control, ensuring that the lifting plate 51 can accurately reach the predetermined position each time, thereby accurately adjusting the position of the driving rod 41. At the same time, through the stable operation of the first lifting motor, the movement of the lifting plate 51 is smoother, reducing the instability factors that may be caused by manual operation.

[0045] According to some embodiments of the present application, the top of the shell 10 is further provided with a plurality of guide rods 52 extending in the height direction, and the lifting plate 51 is provided with guide holes corresponding to the plurality of guide rods 52, and the plurality of guide rods 52 are movably arranged in the corresponding guide holes.

[0046] In some embodiments, the lifting plate 51 is provided with a plurality of guide holes, and the position and number of each guide hole correspond one-to-one with the guide rods 52 on the top of the shell 10. The plurality of guide rods 52 pass through the corresponding guide holes to allow the lifting plate 51 to move in the vertical direction. It can be understood that the combination of the guide rods 52 and the guide holes constitutes a guide system, which restricts the movement of the lifting plate 51 in the vertical direction and only allows the lifting plate 51 to move linearly up and down. The cooperation of the guide rods 52 and the guide holes makes the lifting plate 51 stable when moving up and down, reducing the possibility of shaking or deviation.

[0047] Therefore, the design of the guide system ensures the stability of the lifting plate 51 when moving up and down, prevents the lifting plate 51 from tilting or swinging during movement, thereby ensuring the smoothness of the entire grouting pipe assembly work, and through the cooperation of the guide rod 52 and the guide hole, the lifting plate 51 can smoothly move in the vertical direction and will not deviate from the predetermined track, ensuring the accuracy of the driving device 40 when switching at different positions, and in particular, the combination of the guide rod 52 and the guide hole makes the movement of the lifting plate 51 more reliable, which can maintain good performance even after long-term use, thereby enhancing the working reliability of the grouting pipe assembly.

[0048] Finally, it should be pointed out that the above preferred embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined in the claims of the present application.
