Description

Technical Field

[0001] The utility model belongs to the technical field of road repair, and in particular relates to a highway pavement crack repairing mechanism. Background Art

[0002] During the long-term use of highway pavement, due to the influence of heavy vehicle loads or geological factors, certain road cracks will appear. Generally, existing road crack repair mechanisms include vacuum cleaners, grouting components and repair material recovery components. When in use, the vacuum cleaner is first used to clean the debris in the cracks, and then the grouting components are used to grout the cleaned cracks to repair them, thereby achieving the repair of highway pavement cracks.

[0003] However, during the implementation of this technical solution, due to the irregular shape of the cracks and the errors in the trajectory of the workers pushing the vehicle, the grouting components are easy to deviate from the cracks to be repaired, the repair accuracy is not high, and the repair effect is poor, which leads to the waste of repair materials and increases economic losses. Therefore, there is an urgent need for a highway pavement crack repair mechanism with high repair accuracy and economic repair materials. Utility Model Content

[0004] In view of the above problems, the utility model provides a highway pavement crack repairing mechanism.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a highway pavement crack repair mechanism, including a repair vehicle main body mechanism, the repair vehicle main body mechanism includes a base plate, a storage tank, an integrated box and a fixed plate, the storage tank and the integrated box are both installed on the upper end of the base plate, the fixed plate is installed on the side of the base plate, the highway pavement crack repair mechanism also includes a grouting mechanism, a width probe mechanism and a controller, the grouting mechanism includes a grouting pipe and a grouting cylinder, the grouting pipe is connected to the integrated box, the grouting pipe is installed on the piston rod of the grouting cylinder, the length direction of the piston rod is perpendicular to the side of the fixed plate, and the grouting cylinder is installed on the base plate;

[0006] The width probe mechanism includes a slider, a width probe, a sliding rod, a spring 1, a spring 2, an elastic force sensor 1 and an elastic force sensor 2. The slider is installed at the upper end of the width probe, the slider is slidably connected to the sliding rod, the spring 1 and the spring 2 are respectively fitted with the side surfaces of both ends of the slider, the elastic force sensor 1 is installed on the spring 1, and the elastic force sensor 2 is installed on the spring 2. The lower end of the width probe is located inside the crack to be repaired, and the sliding rod is installed on the side of the fixed plate.

[0007] The controller is installed on the bottom plate, and the grouting cylinder, elastic force sensor 1 and elastic force sensor 2 are all connected to the controller for communication.

[0008] Preferably, the highway pavement crack repair mechanism also includes a depth probe mechanism and a speed regulating valve. The depth probe mechanism is located between the width probe mechanism and the grouting mechanism. The depth probe mechanism includes a probe card slot, a depth probe and a horizontal slide cylinder. The probe card slot is provided with a long hole. The horizontal slide cylinder is horizontally slidably connected to the long hole. The depth probe and the horizontal slide cylinder are vertically slidably connected. The speed regulating valve is communicatively connected to the controller, and the speed regulating valve is installed on the grouting pipe.

[0009] Preferably, the depth probe is an elastic probe.

[0010] Preferably, the highway pavement crack repairing mechanism further comprises a blower, which is installed on the side of the fixing plate and is located at the front end of the width probe mechanism.

[0011] Preferably, the highway pavement crack repair mechanism also includes a compaction mechanism, which includes a compaction cylinder and a compaction plate, wherein the upper end of the compaction cylinder is detachably connected to the fixed plate, and the compaction plate is installed at the lower end of the compaction cylinder.

[0012] Preferably, the highway pavement crack repairing mechanism further comprises a scraping member, which is arc-shaped and is mounted on the side of the fixing plate.

[0013] Preferably, the main body structure of the repair vehicle further includes a universal wheel and a push rod, wherein the universal wheel is mounted on the lower end of the base plate, and the push rod is mounted on the upper end of the base plate.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] (1) The lower end of the width probe is located inside the crack to be repaired. The length direction of the crack is often irregular. When the crack tilts to one side, the width probe moves to the corresponding side. At this time, spring 1 or spring 2 is squeezed, and elastic sensor 1 or elastic sensor 2 sends a signal to the controller installed on the bottom plate. The controller sends a signal to the grouting cylinder, and the grouting cylinder drives the grouting pipe to move in the corresponding direction, so that the grouting pipe is always located directly above the crack to be repaired, saving repair materials and achieving good repair effect.

[0016] (2) The depth of the crack is detected in real time based on the change in the height of the depth probe in the vertical direction. Combined with the width of the crack observed by the construction personnel, the grouting flow rate is increased or decreased in real time by controlling the speed regulating valve after judgment, ensuring that the best crack repair effect can be achieved with less repair materials;

[0017] (3) The compaction plate is installed at the lower end of the compaction cylinder. The compaction plate moves vertically periodically through the compaction cylinder to achieve compaction so that the repair material fills the cracks as much as possible;

[0018] (4) The hair dryer is installed on the side of the fixed plate. The hair dryer removes the dust in the cracks. Compared with a vacuum cleaner, the hair dryer can clean larger dust more thoroughly.

[0019] (5) The scraper is installed on the side of the fixed plate. The scraper spreads the excess repair material toward the surrounding area, avoiding drastic changes in the height of the crack and enhancing the connection strength between the repair material and the road surface;

[0020] (6) The depth probe is an elastic probe that can be bent, thus ensuring that the depth probe will not interfere with the overall operation of the road pavement crack repair mechanism. After being bent, the elastic probe will rebound to its original shape, and the change in crack depth is determined based on the vertical expansion and contraction of the elastic probe after bending and rebounding.

Figure 2 and Figure 3 As shown, the highway pavement crack repair mechanism also includes a grouting mechanism 2, a width probe mechanism 5 and a controller. The grouting mechanism 2 includes a grouting pipe 21 and a grouting cylinder 22. The grouting pipe 21 is connected to the integrated box 14. The grouting pipe 21 is installed on the piston rod of the grouting cylinder 22. The length direction of the piston rod is perpendicular to the side of the fixed plate 15. The grouting cylinder 22 is installed on the base plate 11.

[0039] like Figure 3 As shown, the width probe mechanism 5 includes a slider 51, a width probe 52, a sliding rod 53, a spring 1 54, a spring 2 55, an elastic force sensor 1 and an elastic force sensor 2. The slider 51 is installed at the upper end of the width probe 52, and the slider 51 is slidably connected to the sliding rod 53. The spring 1 54 and the spring 2 55 are respectively fitted to the side surfaces of the slider 51 at both ends. The elastic force sensor 1 is installed on the spring 1 54, and the elastic force sensor 2 is installed on the spring 2 55. The lower end of the width probe 52 is located inside the crack to be repaired, and the sliding rod 53 is installed on the side of the fixed plate 15.

[0040] The controller is installed on the bottom plate 11, and the grouting cylinder 22, elastic force sensor 1 and elastic force sensor 2 are all connected to the controller for communication.

[0041] like Figure 2 and Figure 3As shown, the highway pavement crack repair mechanism also includes a depth probe mechanism 6 and a speed regulating valve. The depth probe mechanism 6 is located between the width probe mechanism 5 and the grouting mechanism 2. The depth probe mechanism 6 includes a probe card slot 61, a depth probe 62 and a horizontal slide cylinder 63. A long hole is opened on the probe card slot 61. The horizontal slide cylinder 63 is horizontally slidably connected with the long hole. The depth probe 62 and the horizontal slide cylinder 63 are vertically slidably connected. The speed regulating valve is communicatively connected with the controller, and the speed regulating valve is installed on the grouting pipe 21.

[0042] The depth probe 62 is a spring probe.

[0043] like Figure 2 and Figure 3 As shown, the highway pavement crack repairing mechanism also includes a blower 4 , which is installed on the side of the fixing plate 15 and is located at the front end of the width probe mechanism 5 .

[0044] like Figure 2 and Figure 3 As shown, the highway pavement crack repair mechanism also includes a compaction mechanism 3, which includes a compaction cylinder 31 and a compaction plate 32. The upper end of the compaction cylinder 31 is detachably connected to the fixed plate 15, and the compaction plate 32 is installed at the lower end of the compaction cylinder 31. The compaction cylinder 31 performs reciprocating linear motion in the vertical direction.

[0045] like Figure 2 and Figure 3 As shown, the road pavement crack repair mechanism also includes a scraping member 7 , which is arc-shaped and is installed on the side of the fixing plate 15 .

[0046] like Figure 5 As shown, the repair vehicle main body 1 further includes a universal wheel 12 and a push rod 16 . The universal wheel 12 is mounted on the lower end of the base plate 11 , and the push rod 16 is mounted on the upper end of the base plate 11 .

[0047] Working principle of highway pavement crack repair mechanism:

[0048] The main body 1 of the repair vehicle is driven to move by pushing the push rod 16. At this time, the width probe 52 and the depth probe 62 are both located inside the crack to be repaired, and the grouting pipe 21 is located directly above the crack. With the movement of the main body 1 of the repair vehicle, when the crack tilts to the left or right, the slider 51 is slidably connected to the sliding rod 53, so the width probe 52 moves to the corresponding side. At this time, the spring 1 54 or the spring 2 55 is squeezed, and the elastic sensor 1 or the elastic sensor 2 sends a signal to the controller, and the controller sends a signal to the grouting cylinder 22. Since the grouting pipe 21 is detachably connected to the piston rod of the grouting cylinder 22, the grouting cylinder 22 drives the grouting pipe 21 to move in the corresponding direction as a whole, so that the grouting pipe 21 is always located directly above the crack to be repaired.

[0049] When the push rod 16 is pushed to drive the repair vehicle main body 1 to move along the crack direction, the depth probe 62 rises or falls in the vertical direction due to the change in the crack depth. According to the rise or fall of the depth probe 62 in the vertical direction, it is determined whether the crack to be repaired becomes deeper or shallower, so that the worker can control the speed regulating valve to adjust the output amount of the repair material in real time, thereby achieving real-time regulation;

[0050] The width and depth of the cracks in the road section to be processed are intuitively displayed through the width probe mechanism 5 and the depth probe mechanism 6, which is convenient for construction personnel to take corresponding operations to increase or reduce the flow of repair materials, thereby saving repair materials while ensuring the repair effect.

[0052] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields.
