Description

Technical Field

[0001] The utility model relates to the technical field of road maintenance, and more specifically, to a pre-slit opening and grouting integrated road maintenance device. Background Art

[0002] During the use of roads, road surface damage often occurs due to the impact of moving vehicles, impact, wear and tear, and weather changes. Road surface damage will have a harmful impact on vehicle driving, traffic safety, and environmental protection, so road maintenance is necessary.

[0003] Pre-crack grouting is a commonly used method in road maintenance. It can deal with cracks caused by road damage. The purpose of pre-crack grouting is to prevent further expansion of cracks and water infiltration, thereby improving the sealing and durability of the road, reducing the frequency of road maintenance and replacement, and extending the service life of the road.

[0004] The pre-slit grouting project starts with pre-slits, using a pavement cutting machine to cut seams on the road surface. The seams are usually straight and run along the longitudinal or transverse direction of the road. The seams are then cleaned to ensure there is no debris around them. The grouting material is then poured into the seams, and finally compacted using specific tools to ensure that the grouting material fits fully with the road surface.

[0005] When cutting seams on the road surface, since the road has multiple horizontal lanes, the pressure of vehicles driving along the lanes for a long time causes the flatness of the road to change, resulting in unevenness or bulges between a single lane or two lanes. When cutting horizontally along the road surface through the raised ground, the cutting depth of the road cutter's cutting blade on the road surface increases, resulting in increased cutting resistance. In severe cases, the road cutter's cutting blade may get stuck. Utility Model Content

[0027] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Refer to the instruction manual Figures 1 to 7 A pre-slit and pre-filled integrated road maintenance equipment includes a vehicle body 1, which includes a load-bearing plate and wheels, and four groups of wheels are arranged at the four corners of the bottom of the load-bearing plate. A box body 2 is installed on the load-bearing plate of the vehicle body 1, and the box body 2 includes a cutting box 21. A drive seat 211 is provided inside the cutting box 21, and a detection component 5 is provided on one side of the drive seat 211; the bottom of the drive seat 211 is transmission-connected with a cutting knife 212, and linear guide rails 213 are installed at both ends of the drive seat 211, and the linear guide rails 213 are used to drive the drive seat 211 to move vertically; the detection component 5 includes a detection box 51, and a detection wheel 52 passes through the bottom of the detection box 51, and the top of the detection wheel 52 is rotatably connected to a wheel bracket 53, and one end of the wheel bracket 53 is fixedly connected to a proximity switch conductor 54, and a proximity switch sensor head 55 is provided just above the proximity switch conductor 54.

[0029] It should be noted that a handlebar is installed at one end of the supporting plate for pushing the vehicle body 1 to move. A driving motor, a battery and a control switch are installed inside the driving seat 211. The driving motor and the cutting knife 212 are connected by a chain or belt transmission. The battery is used to provide working power. The control switch adopts an existing remote control switch, and the control switch includes a driving motor switch and a linear guide 213 switch. The proximity switch conductor 54 and the proximity switch sensor head 55 are proximity switch components of the prior art. The proximity switch sensor head 55 is electrically connected to an alarm. When the proximity switch conductor 54 approaches the proximity switch sensor head 55 to trigger the switch, the alarm sounds an alarm. The above-mentioned electrical control and electrical connection are common operations for those skilled in the art.

[0030] Furthermore, a mounting block 511 is detachably mounted on the inner wall of one end of the detection box 51 corresponding to the proximity switch sensing head 55, a guide rod 512 passes through the interior of the mounting block 511, and the bottom end of the guide rod 512 is fixedly connected to the proximity switch sensing head 55, and a spring member 513 is fixedly connected between the wheel bracket 53 and the top end of the detection box 51 and between the proximity switch sensing head 55 and the mounting block 511.

[0031] It should be noted that when the proximity switch conductor 54 contacts and pushes up the proximity switch sensor head 55, the guide rod 512 moves upward through the mounting block 511, and at the same time the spring member 513 on the proximity switch sensor head 55 is compressed to prevent the proximity switch sensor head 55 from being squeezed and damaged.

[0032] Furthermore, openings are provided at the bottom of the cutting box 21 corresponding to the positions of the cutting blade 212 and the detection wheel 52 , and the bottom of the detection wheel 52 and the bottom of the wheels of the vehicle body 1 roll along the road.

[0033] Furthermore, a horizontal calibration seat 3 is correspondingly provided at one end of the driving seat 211, and a fixing plate 31 is fixed at the bottom of the horizontal calibration seat 3. A vertical calibration rod 32 passes through one end of the fixing plate 31, and the fixing plate 31 and the vertical calibration rod 32 are positioned by bolts, and the vertical calibration rod 32 is horizontally aligned with the cutting knife 212.

[0034] It should be noted that the fixing plate 31 and the vertical calibration rod 32 are vertically arranged, and the bolts are transversely screwed into the fixing plate 31 to position the vertical calibration rod 32.

[0035] Furthermore, a water spray seat 214 is provided at one end of the detection box 51 , and the water spray seat 214 is located at one side of the cutting blade 212 , and a nozzle 215 is fixedly provided on the side of the water spray seat 214 corresponding to the cutting blade 212 .

[0036] Furthermore, the box body 2 also includes a storage box 22, and the storage box 22 is fixedly arranged on one side of the cutting box 21. A water cavity 221 is provided inside the storage box 22, and the water cavity 221 is connected to the water spray seat 214 through a pipe.

[0037] It should be noted that the water spray seat 214 is located on one side of the driving seat 211 to avoid blocking the vertical movement of the driving seat 211. A water pump is installed inside the water chamber 221. When the cutting knife 212 is cutting, the water chamber 221 supplies water to the water spray seat 214, and the water is sprayed to the cutting knife 212 through the nozzle 215, so that the cutting knife 212 cools down during the cutting operation.

[0038] In this embodiment, the implementation scenario is specifically as follows: first, a cutting route is drawn on the road surface with lime, and the vehicle body 1 is pushed along the cutting route by the handlebars. When the vehicle body 1 moves, the vertical calibration rod 32 coincides with the cutting route, indicating that the cutting knife 212 moves along the cutting route. The detection wheel 52 is pushed to the bottom of the cutting box 21 and contacts the ground by the spring member 513 at its top. The linear guide rail 213 drives the driving seat 211 to descend, so that the cutting knife 212 extends to the bottom of the cutting box 21. At this time, according to the walking direction of the vehicle body 1, the detection wheel 52 is in front and the cutting knife 212 is in the back. The cutting knife 212 performs pre-slit cutting on the road surface along the cutting route. When the protrusion height of the ground protrusion A on the road surface is greater than the setting range of the proximity switch, the setting range of the proximity switch is the proximity switch conductor 54 and the proximity switch sensor. The detection wheel 52 is first lifted by the ground protrusion A, and the proximity switch conductor 54 moves upward and close to the proximity switch sensing head 55, so that the proximity switch sensing head 55 is turned on and the alarm is triggered. At this time, the vehicle body 1 is stopped from being pushed, and then the driving seat 211 and the cutting knife 212 are lifted upward by the linear guide rail 213. Then, the vehicle body 1 is pushed until the ground protrusion A is seen, so that the cutting knife 212 bypasses the ground protrusion A, and finally the cutting knife 212 is lowered to continue cutting to prevent the cutting knife 212 from getting stuck when cutting the ground protrusion A. The lower ground protrusion A can be cut directly. For the ground protrusion A whose height exceeds the setting range of the proximity switch, it is chosen to skip the ground protrusion A first, and then the ground protrusion A is leveled before cutting, thereby ensuring the smooth progress of the pre-slit work.

[0039] Refer to the instruction manual Figure 1 、 Figure 2 and Figure 8 After the above-mentioned pre-slit cutting work is completed, the cut seams need to be filled and leveled, and the seams are filled and leveled using polymer modified materials or other caulking materials. The utility model also provides a caulking device, the specific structure of which is as follows: a discharge tap 4 is fixedly provided on the side of the storage box 22 away from the cutting box 21, a caulking material chamber 222 is provided at the bottom of the water chamber 221, and the caulking material chamber 222 is connected to the discharge tap 4 through a pipeline, and a switch handle is rotatably provided on the top of the discharge tap 4, and a switch pull rod 41 is rotatably connected to the switch handle.

[0040] It should be noted that a feed pump is installed inside the caulking material cavity 222, and caulking material is provided inside the caulking material cavity 222. The caulking material is transported to the discharge tap 4 by the feed pump, and the switch handle on the top of the discharge tap 4 is opened by pulling the switch rod 41 to one end to allow the caulking material to flow out.

[0041] Furthermore, a material guide trough plate 42 is provided at the bottom of the discharge faucet 4, and a material drop ring 43 is provided at the bottom end of the material guide trough plate 42. One end of the material drop ring 43 is fixedly connected to a support rod 44. The support rod 44 and the switch pull rod 41 are both provided on the handlebar of the vehicle body 1.

[0042] It should be noted that the material guide chute plate 42 is set at an angle, the top end of the material guide chute plate 42 is rotatably connected to the outer side of the storage box 22, the bottom end of the material guide chute plate 42 is placed on the inner side of the blanking ring 43, and the support rod 44 pulls the blanking ring 43 away from one end of the material guide chute plate 42. By pulling the support rod 44 upward, the height of the blanking ring 43 can be adjusted and the inclination angle of the material guide chute plate 42 can be changed.

[0043] In this embodiment, the implementation scenario is specifically as follows: after the pre-slit cutting work is completed, the cutting knife 212 is retracted, and on the return journey, the blanking ring 43 is pressed against the seam and moves along the seam following the vehicle body 1, and the feed pump conveys the caulking material inside the caulking material cavity 222 to the discharge tap 4, and the switch handle on the top of the discharge tap 4 is opened. The caulking material flowing out of the discharge tap 4 flows into the seam through the guidance of the guide trough plate 42, and the blanking ring 43 plays a blocking role on the outer periphery of the seam, and the whole can be caulked during the return journey. Under the guidance of the guide trough plate 42 and the encirclement of the blanking ring 43, the seams can be accurately caulked, thereby improving work efficiency.

[0044] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
