Technical Field
[0001] This utility model relates to the field of road construction technology, specifically to a road construction damage repair device. Background Technology
[0002] During long-term use, roads are prone to various degrees of damage, such as cracks and potholes, due to repeated vehicle loads, changes in natural temperature and humidity, and uneven ground settlement. If the damaged areas are not repaired in time, the damage will continue to expand, not only reducing the comfort of road travel but also further shortening the overall service life of the road, and in severe cases, even causing traffic accidents.
[0003] The Chinese utility model patent with authorization announcement number "CN218454329U" is specifically titled "A Road Dust-Collecting Repair Device Based on Green Building Construction". It includes a base plate, a baffle at the rear end of the top surface of the base plate, a storage box located close to the baffle on the top surface of the base plate, a top cover on the top surface of the storage box, an injection pump located on the left side of the storage box near the bottom, and an injection tube connected to the output port of the injection pump. A dust collection box is located on the top surface of the base plate close to the storage box, and a dust collection pipe is located on the left side of the dust collection box near the bottom. This road dust-collecting repair device based on green building construction cleans the road surface through the dust collection pipe and dust collection head, which is beneficial for the repair of the road surface by the repair material and avoids the impact of impurities in the damaged road surface on the repair effect of the repair agent. A dust collection bag is installed in the dust collection box to facilitate the cleaning of collected dust and impurities. Furthermore, the placement rack facilitates the placement and retrieval of the dust collection pipe and dust collection head.
[0004] In the aforementioned device, cleaning is performed using a vacuum head, but its suction coverage area is relatively small. Multiple repositioning of the vacuum head is required to complete a thorough cleaning. Damaged road surfaces often contain highly adhesive impurities, such as long-accumulated dirt and gel-like substances. The vacuum head struggles to effectively remove these impurities from the road surface, and the residual adhesive impurities can affect the adhesion of subsequent repair materials to the road surface. Therefore, those skilled in the art provide a road construction damage repair device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to provide a road construction damage repair device to solve the problems mentioned in the background art.
[0006] This utility model provides the following technical solution: a road construction damage repair device, including a vehicle-mounted plate, four movable wheels are fixedly installed at the four opposite corners of the bottom end of the vehicle-mounted plate, a storage box is provided at the top of the vehicle-mounted plate, an injection pump is fixedly installed at the top of the vehicle-mounted plate and the injection pump is located on one side of the storage box, and an injection head is provided at the top of the storage box.
[0007] A collection tank is fixedly installed at the top of the vehicle-mounted plate away from the injection pump. A dust collection mechanism is fixedly installed at the top of the collection tank. A connecting pipe is fixedly connected to the outer wall of the collection tank. Two guide rails are fixedly installed at the top of the vehicle-mounted plate away from the collection tank. A dust collection and cleaning component is provided on one side of the two guide rails. Two guide blocks are slidably fitted inside one side of each of the two guide rails.
[0008] As a preferred embodiment of the above technical solution, the vacuum cleaning component includes a support frame plate fixedly installed on one side of the guide block. A rectangular channel is provided on the top surface of the support frame plate. A collection cover is fixedly connected to the top surface of the support frame plate and the rectangular channel. One end of the collection cover is fixedly installed on the end of the connecting pipe away from the collection tank. The guide block moves vertically up and down inside the guide rail plate to push the vacuum cleaning component to move vertically up and down.
[0009] As a preferred embodiment of the above technical solution, the interior of the bearing frame plate is provided with a cavity shape, and two inclined guide plates are fixedly connected to both sides of the inner wall of the bearing frame plate. The two inclined guide plates are symmetrically arranged inside the bearing frame plate, and the inclined guide plates are used to guide impurities upward.
[0010] As a preferred embodiment of the above technical solution, a trapezoidal cover is fixedly connected to the bottom end of the bearing frame plate. The top of the trapezoidal cover is opened into a rectangular opening shape, and the bottom of the trapezoidal cover is set in a trapezoidal shape. The bottom of the trapezoidal cover is located above the road surface and does not contact it.
[0011] As a preferred embodiment of the above technical solution, both the trapezoidal cover and the inclined guide plate are fixedly connected to a sealing plate at their ends, and the sealing plate is used to seal the end of the inclined guide plate. A drive motor is fixedly installed at the end of the trapezoidal cover away from the sealing plate, and a brush roller is fixedly connected to the output end of the drive motor.
[0012] As a preferred embodiment of the above technical solution, the brush roller is rotatably installed inside the trapezoidal cover, and the lower surface of the brush roller extends out of the bottom of the trapezoidal cover.

[0013] As a preferred embodiment of the above technical solution, a bristle plate is fixedly connected to one side of the inner wall of the trapezoidal cover, and the bristle plate is located above the brush roller. The brush roller rotates clockwise below the bristle plate to scrape off adhering impurities from the surface of the brush roller.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This invention utilizes a vacuum cleaning component, a collection tank, and a vacuuming mechanism. A drive motor rotates a brush roller clockwise. The lower surface of the rotating brush roller sweeps away stubborn impurities adhering to the damaged surface. The brush roller lifts up the impurities that were firmly attached to the surface, and the negative pressure suction generated by the trapezoidal cover directly sucks the swept-up impurities into the interior. When the brush roller rotates clockwise to the position of the upper bristle plate, the bristles of the bristle plate embed into the gaps between the brush bristles of the brush roller, scraping off the impurities entangled and adhering to the brush bristles. This prevents impurities from adhering to the brush roller for a long time and affecting the cleaning effect. Compared with traditional vacuum heads, this invention expands the cleaning range, reduces cleaning time and costs, and facilitates the cleaning of highly adhesive impurities, preventing these impurities from affecting the subsequent repair and bonding quality.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Please see Figures 1 to 4As shown, this utility model provides a technical solution: a road construction damage repair device, including a vehicle-mounted plate 1, four moving wheels 2 fixedly installed at the four opposite corners of the bottom end of the vehicle-mounted plate 1, a storage box 3 set at the top of the vehicle-mounted plate 1, an injection pump 4 fixedly installed at the top of the vehicle-mounted plate 1, and the injection pump 4 is located on one side of the storage box 3, an injection head 5 is set at the top of the storage box 3, a collection tank 6 is fixedly installed at the top of the vehicle-mounted plate 1 away from the injection pump 4, a dust suction mechanism 7 is fixedly installed at the top of the collection tank 6, a connecting pipe 8 is fixedly connected to the outer wall of the collection tank 6, two guide rails 10 are fixedly installed at the end of the vehicle-mounted plate 1 away from the collection tank 6, a dust suction cleaning component 9 is set on one side of the two guide rails 10, and two guide blocks 101 are slidably sleeved inside one side of the two guide rails 10 respectively.
[0023] It should be noted that the entire device can move flexibly by relying on the vehicle-mounted plate 1 and the moving wheels 2, and can quickly reach the damaged road surface. The dust collection mechanism 7 works with the dust collection and cleaning component 9 through the connecting pipe 8. First, it uses negative pressure to adsorb and clean the impurities and stubborn adhesive impurities on the damaged road surface. At the same time, it uses the existing negative pressure adsorption dust collection head to clean the impurities in the grooves of the damaged road surface. The dust collection head here is existing technology and will not be described in detail or shown in the figure. The debris generated during cleaning is sent to the collection tank 6 for temporary storage. After cleaning, the repair material in the storage box 3 is transported to the injection head 5 by the injection pump 4. The injection head 5 accurately injects the repair material into the damaged road surface. The height of the dust collection and cleaning component 9 off the ground is adjusted by the up and down sliding of the guide block 101 on the guide rail plate 10.
[0024] It should be noted that a BYGH stepper motor is selected, which is compatible with the guide rail plate 10 and guide block 101 for linear up-and-down sliding. The injection pump 4 is a small stainless steel micro gear pump KCB-83.3, suitable for conveying fluid materials such as asphalt and repair mortar, with stable flow rate suitable for road grouting repair. The dust collection mechanism 7 uses an industrial high-pressure vortex blower HG-2200, which has strong negative pressure suction and can efficiently remove fine dust and gravel particles from road potholes. The injection head 5 uses a wear-resistant conical grouting nozzle DN25, which is a common standard accessory for road repair. Moreover, the injection pump 4, dust collection mechanism 7, and injection head 5 are all existing mature technologies, and will not be described in detail here. The selected models are not restricted here.
[0025] It should be noted that a discharge port is provided on the bottom side wall of the storage tank 3, and a connecting joint with internal threads is welded to the discharge port. One end of the conveying pipeline is sealed to this connecting joint through external threads, and a sealing gasket is fitted at the connection. The other end of the conveying pipeline is fixedly connected to the inlet of the injection pump 4. The connection method adopts a snap-fit sealing connection to ensure no leakage during material conveying. The discharge port of the injection pump 4 is connected to the inlet of the injection head 5 through another section of conveying pipeline. This section of pipeline is a flexible metal hose, and a nitrile rubber sealing gasket is used at the connection between the storage tank 3 and the conveying pipeline. An electromagnetic control valve is provided at the discharge end of the injection head 5. This electromagnetic control valve is electrically connected to the control module of the device. The control module can be a PLC controller, and the operator can control it through the control panel. The start / stop button on the board controls the on / off state of the electromagnetic control valve, thereby controlling the start and stop of grouting. To adapt to the grouting needs of different damaged areas, this application sets up an adjustable flow regulation structure. A flow regulation valve is connected in series on the delivery pipeline between the injection pump 4 and the injection head 5. The flow regulation valve adopts a knob-type adjustment structure, and an adjustable throttling plate is set inside the valve. By rotating the knob, the opening size of the throttling plate is changed, thereby adjusting the material delivery flow rate. Secondly, for road potholes and cracks of different specifications and depths, this application uses manual hand-held holding of the injection head 5 to flexibly adjust the position, angle and insertion depth. On-site, the injection head 5 can be directly aligned with the damaged area to complete the grouting and filling, which can adapt to various road damage repair scenarios.
[0026] It should be further noted that the aforementioned electromagnetic control valves and flow regulating valves are all common and mature existing devices in the fields of road maintenance and fluid grouting. They are standard accessories in this field, and there is no need to elaborate on their internal structure and circuit principle. Commonly used and practical models are listed below: Electromagnetic control valve: DF-25 type fluid electromagnetic grouting valve, 2W-320-32 universal straight-through electromagnetic control valve; Flow regulating valve: QJ-L10 grouting manual flow regulating valve, ZJL type small fluid throttling regulating valve.
[0027] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2 As shown, the vacuum cleaning assembly 9 includes a support frame plate 91 fixedly installed on one side of the guide block 101. A rectangular channel 92 is opened on the top surface of the support frame plate 91. A collection cover 93 is fixedly connected to the top surface of the support frame plate 91 and the rectangular channel 92. One end of the collection cover 93 is fixedly installed on the end of the connecting pipe 8 away from the collection tank 6. The guide block 101 moves vertically up and down inside the guide rail plate 10 to push the vacuum cleaning assembly 9 to move vertically up and down.
[0028] It should be noted that during the process of driving the vacuuming mechanism 7, a negative pressure airflow is formed inside the collection tank 6, which is further transmitted to the collection hood 93 through the connecting pipe 8. A stable negative pressure is formed inside the collection hood 93, which further transmits the negative pressure airflow to the inside of the support frame plate 91 through the rectangular channel 92. The stepper motor 42BYGH40 drives the guide block 101 to move up and down along the inside of the guide rail plate 10, and further moves the vacuuming and cleaning components 9 (collection hood 93 and support frame plate 91) away from or closer to the damaged road surface.
[0029] It should be further explained that a dust removal and filtration structure is installed on the inner wall of the top of the collection tank 6. This dust removal and filtration structure uses a stainless steel woven filter or industrial-grade non-woven filter cotton. When the fan blades inside the dust collection mechanism 7 rotate at high speed by the motor, a negative pressure is formed inside the collection tank 6. Under the action of negative pressure, dust and impurities on the road are sucked into the connecting pipe 8 through the collection hood 93, and then enter the tank through the feed inlet of the collection tank 6. The dust-laden airflow first passes through the filter screen, which further intercepts particulate impurities or dust in the airflow inside the collection tank 6. The filtered clean airflow enters the dust collection mechanism 7 through the exhaust port, and then is discharged from the exhaust port of the dust collection mechanism 7, thereby preventing dust and impurities from entering the dust collection mechanism 7. Secondly, when dust and impurities accumulate inside the collection tank 6, the outer wall of the collection tank 6 itself is equipped with a door. The operator can close the dust collection mechanism 7, unscrew the locking bolts, remove the door, and clean the dust and impurities accumulated inside the collection tank 6. At the same time, existing hand-held brushes and other tools can be used to clean the bottom of the filter screen.
[0030] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, the interior of the support frame plate 91 has a cavity shape. Two inclined guide plates 96 are fixedly connected to both sides of the inner wall of the support frame plate 91. The two inclined guide plates 96 are symmetrically arranged inside the support frame plate 91, and the inclined guide plates 96 are used to guide impurities upward. A trapezoidal cover 95 is fixedly connected to the bottom end of the support frame plate 91. The top of the trapezoidal cover 95 is a rectangular opening, and the bottom of the trapezoidal cover 95 is trapezoidal. The bottom of the trapezoidal cover 95 is located above the road surface and does not contact it.
[0031] It should be noted that when the damaged road surface contains floating dust, loose gravel, or highly adhesive impurities, the entire vacuum cleaning component 9 moves down to be closer to the damaged road surface. The trapezoidal cover 95 expands the coverage area of the negative pressure vacuum, enabling it to adsorb floating dust, debris, or highly adhesive impurities from the damaged road surface area upwards. After the impurities enter the interior of the supporting frame plate 91, the relatively inclined guide plate 96 guides and converges the airflow carrying the impurities, directing the airflow and impurities upwards along the inclined surface to the rectangular channel 92. Finally, the impurities are sent into the collection tank 6 through the collection cover 93 and connecting pipe 8 to complete the collection and cleaning of the impurities. Compared with the existing technology that uses a vacuum head, this method expands the cleaning range of the damaged road surface, enabling the cleaning of highly adhesive impurities. The vacuum head has a limited cleaning range for the damaged road surface, increasing cleaning time and costs, and making it inconvenient to clean highly adhesive impurities, thus reducing the cleaning effect of the damaged road surface. On the other hand, it avoids the impact of highly adhesive impurities on the subsequent repair and bonding quality.
[0032] As one implementation method in this embodiment, please refer to Figures 2 to 4 As shown, both the trapezoidal cover 95 and the inclined guide plate 96 are fixedly connected to a sealing plate 97 at their ends, and the sealing plate 97 is used to seal the end of the inclined guide plate 96. A drive motor 98 is fixedly installed at the end of the trapezoidal cover 95 away from the sealing plate 97. A brush roller 99 is fixedly connected to the output end of the drive motor 98. The brush roller 99 is rotatably installed inside the trapezoidal cover 95, and the lower surface of the brush roller 99 extends out of the bottom of the trapezoidal cover 95. The lower surface of the brush roller 99 contacts the road surface and is used to clean stubborn impurities adhering to the damaged road surface. A bristle plate 910 is fixedly connected to one side of the inner wall of the trapezoidal cover 95, and the bristle plate 910 is located above the brush roller 99. The brush roller 99 rotates clockwise below the bristle plate 910 to scrape off the adhering impurities from the surface of the brush roller 99.
[0033] It should be noted that when the brush roller 99 moves down to the damaged road surface along with the dust collection and cleaning component 9, the drive motor 98 drives the brush roller 99 to rotate clockwise. The lower surface of the rotating brush roller 99 rotates and sweeps away the stubborn impurities adhering to the damaged road surface. The brush of the brush roller 99 here is made of relatively hard plastic material, using hard nylon PA66 material, or modified polypropylene hard PP can also be used. It has high hardness, wear resistance and aging resistance, and is not easy to shed or deform when rubbing against rough road surfaces, and is resistant to road surface sand and gravel abrasion. The brush roller 99 sweeps up the impurities that were originally firmly attached to the road surface. With the negative pressure suction generated by the trapezoidal cover 95, the swept impurities are directly sucked into the interior. When the brush roller 99 rotates clockwise to the position of the upper bristle plate 910, the bristles of the bristle plate 910 are embedded in the gaps between the bristles of the brush roller 99, scraping off the impurities wrapped and attached to the bristles of the brush roller 99. This prevents the impurities from being attached to the brush roller 99 for a long time and affecting the cleaning effect. The scraped impurities are also transported to the collection cover 93 along with the negative pressure airflow, and then further transported to the collection tank 6 through the connecting pipe 8.
[0034] Working principle:
[0035] When using this utility model, the operator first pushes the device to the damaged road surface to be repaired by the moving wheel 2, adjusts the position of the device so that the dust suction cleaning component 9 is aligned with the damaged road surface area, and then starts the stepper motor to drive the guide block 101 to slide down along the guide rail plate 10, pushing the dust suction cleaning component 9 to move down as a whole until the lower surface of the brush roller 99 is in contact with the damaged road surface.
[0036] Next, the vacuuming mechanism 7 and the drive motor 98 are started. The drive motor 98 drives the brush roller 99 to rotate clockwise. The rotating brush roller 99 sweeps away the stubborn impurities adhering to the damaged road surface and removes the firmly adhered impurities from the road surface. At the same time, the operation of the vacuuming mechanism 7 creates a negative pressure inside the collection tank 6. The negative pressure is transmitted to the support frame plate 91 and the trapezoidal cover 95 through the connecting pipe 8 and the collection cover 93. A stable negative pressure suction is formed at the bottom of the trapezoidal cover 95. The swept impurities, the original floating dust on the road surface and the loose gravel are directly sucked upward into the trapezoidal cover 95. Then, under the guiding and converging effect of the inclined guide plate 96, the airflow carrying impurities rises through the rectangular channel 92 into the collection cover 93, and is then transported to the collection tank 6 through the connecting pipe 8 for temporary storage.
[0037] Finally, when the brush roller 99 rotates to the position of the upper bristle plate 910, the bristles of the bristle plate 910 will scrape off the impurities entangled and adhered in the gaps between the bristles of the brush roller 99. The scraped-off impurities are also carried away by the negative pressure airflow. After the impurities on the damaged road surface are cleaned, the stepper motor drives the dust collection and cleaning component 9 to move up away from the road surface, and further starts the injection pump 4 to transport the repair material in the storage box 3 to the injection head 5. The injection head 5 is then precisely injected with the repair material into the cleaned damaged potholes to complete the road surface repair operation.
[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
