Description

Technical Field

[0001] This invention belongs to the field of traffic engineering construction technology, and specifically relates to a crack repair device for highway construction with a cleaning function. Background Technology

[0002] Currently, after the construction of traffic roads, cracks appear in some road surfaces due to the frequent pressure of vehicles. If these cracks are not repaired in time, rainwater will seep into the road surface structure layer, leading to problems such as loosening of the road surface layer and potholes. Therefore, it is necessary to use road crack repair devices to repair road cracks in a timely manner.

[0003] For example, patent authorization announcement number CN219410480U discloses a road surface crack detection and repair device for traffic engineering construction, including a mixing tank. A motor is fixedly installed on the top of the mixing tank via a bracket. The output shaft of the motor is fixedly installed with a first rotating rod via a coupling. The bottom end of the first rotating rod passes through the mixing tank and extends into the interior of the mixing tank. This utility model uses a rotating threaded rod to drive a scraper to descend. When the bottom of the scraper is in contact with the top of the ground, the solenoid valve on the surface of the discharge pipe is opened, and then the mixing tank is pushed forward along the crack. The movement of the mixing tank drives the scraper to move, and the movement of the scraper achieves the effect of smoothing the flowing repair agent. In addition, by setting a spring, the scraper can move upward by the spring force when passing through obstacles, thereby preventing the scraper from colliding with obstacles and effectively improving the repair efficiency.

[0004] Based on the search of the aforementioned patent grant announcement numbers, and considering their shortcomings, the following was found: Existing crack repair devices for highway construction are equipped with cleaning and repair components, which are independent of each other. Generally, the cleaning component is used first to clean the cracks in the highway, and then the repair component is used to repair the cleaned cracks. However, in actual use, there are instances where construction workers neglect to use the cleaning component to clean the cracks and instead directly use the repair component to repair them. This can easily lead to quality problems in the repair. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a road construction crack repair device with a cleaning function, comprising a mixing tank, a cleaning component, and a repair component. The mixing tank is equipped with a partition, which divides the mixing tank into a cleaning space and a mixing space. The cleaning component includes a cleaning machine and a cleaning cylinder, with the cleaning cylinder vertically positioned within the cleaning space. The cleaning machine is connected to the cleaning cylinder, which controls the extension or retraction of the cleaning machine from the mixing tank. The repair component is located on the side wall of the mixing tank, positioned behind the cleaning component along the direction of travel of the mixing tank. The device also includes a repair switch, located at the bottom of the cleaning space. When the cleaning machine extends, it locks into a pressing relationship with the repair switch; when it retracts, it releases this pressing relationship. The repair switch is communicatively connected to the repair component and is used to control the opening and closing of the repair component. This solution, by including the repair switch, allows the cleaning machine to move towards the mixing tank when the construction worker operates the cleaning cylinder. After the bottom moves, the cleaning machine begins working once it reaches the designated height, cleaning the cracks in the road. Simultaneously, the cleaning machine presses the repair switch. Because the repair switch is communicatively connected to the repair component, the repair component receives the signal from the repair switch and also begins working. This achieves the function of controlling the cleaning component to work first, followed by the repair component. This solves the problem of existing road crack repair devices, which typically have a cleaning component and a repair component that are not interconnected. Generally, the cleaning component should be used first to clean the road cracks, and then the repair component should be used to repair the cleaned cracks. However, in actual use, there are instances where construction workers neglect to activate the cleaning component to clean the road cracks, and instead directly activate the repair component to repair the road cracks. Such situations can easily lead to quality problems in the repair.

The two ends of the sealing spring are respectively connected to the mixing tank and the end of the connecting plate near the sealing plate.

[0010] As a preferred embodiment of the present invention, the distance between the scraper and the limiting plate is the same as the distance between the output end of the repair cylinder and the other end of the connecting plate.

[0011] As a preferred embodiment of the present invention, the mixing tank is further provided with a horizontal plate and a vertical plate. The horizontal plate is horizontally and sealed within the mixing space, dividing the mixing space into a discharge space. The vertical plate is vertically and sealed at the top of the horizontal plate, dividing the mixing space into a feeding space and an adjustment space. The vertical plate is sealed to the mixing tank. The mixing tank also includes a mixing assembly, which includes a mixing shaft and a mixing motor. The mixing shaft is coaxially disposed within the feeding space, and the mixing motor is coaxially connected to the mixing shaft.

[0012] As a preferred embodiment of the present invention, it further includes a pushing assembly and a pushing rod. A connecting hole is provided on the horizontal plate, which is connected to both the feeding space and the discharging space. The discharging hole is connected to the discharging space. The middle end of the pushing rod is rotatably disposed within the discharging space. The pushing assembly includes a telescopic rod, a hinge rod, and a hinge spring. The pushing rod is hollow inside. The telescopic rod is telescopically disposed at one end of the pushing rod. One end of the hinge rod is horizontally hinged to the telescopic rod.

The repair switch is communicatively connected to the repair component and is used to control the opening and closing of the repair component. This design, by including the repair switch, allows the cleaning machine to move towards the bottom of the mixing tank when the worker operates the cleaning cylinder, thus cleaning the crack. Once the machine reaches the designated height, it begins working to clean the cracks in the road. Simultaneously, the cleaning machine presses the repair switch. Because the repair switch is communicatively connected to the repair component, the repair component also starts working upon receiving the signal from the repair switch. This achieves the function of controlling the cleaning component to work first, followed by the repair component. This solves the problem of existing road crack repair devices, which all have cleaning and repair components that are not interconnected. Generally, the cleaning component should be used first to clean the road cracks, and then the repair component should be used to repair the cleaned road cracks. However, in actual use, there are instances where construction workers neglect to activate the cleaning component to clean the road cracks and directly activate the repair component to repair the road cracks. Such situations can easily lead to quality problems in the repair. Attached Figure Description

Detailed Implementation

[0020] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0021] Please see Figure 1-4This embodiment provides a road construction crack repair device with a cleaning function. First, it should be noted that existing road construction crack repair devices all include a cleaning component 2 and a repair component 3, which are independent of each other. Generally, the cleaning component 2 is used first to clean the road cracks, and then the repair component 3 is used to repair the cleaned cracks. However, in actual use, due to negligence by construction workers, the cleaning component 2 may not be activated to clean the road cracks, and the repair component 3 may be activated directly instead. In situations where crack repair work is being carried out, quality problems can easily arise. Therefore, this solution improves the crack repair device for highway construction, requiring the cleaning component 2 to be activated before the repair component 3. The specific structure is as follows: This solution includes a mixing tank 1, a cleaning component 2, and a repair component 3. The mixing tank 1 is equipped with a partition 101, which divides the mixing tank 1 into a cleaning space 102 and a mixing space 103. The cleaning component 2 includes a cleaning machine 201 and a cleaning cylinder 202, which is vertically positioned... The cleaning machine 201 is installed within the cleaning space 102 and connected to the cleaning cylinder 202. The cleaning cylinder 202 controls the cleaning machine 201 to extend or retract into the mixing tank 1. It should be noted that the bottom of the mixing tank 1 in this design has a connecting groove that communicates with the cleaning space 102. The extension and retraction of the cleaning cylinder 202 controls the cleaning machine 201 to extend outside or retract inside the mixing tank 1. The repair component 3 is installed on the side wall of the mixing tank 1, positioned behind the cleaning component 2 along the running direction of the mixing tank 1. The system also includes a repair switch 301 and a cleaning start switch. Located at the bottom of the cleaning space 102, when the cleaning machine 201 extends out of the mixing tank 1 due to the cleaning cylinder 202 and reaches the specified height, the cleaning machine 201 will press the repair switch 301 and the cleaning start switch. The repair switch 301 is communicatively connected to the repair component 3. When the cleaning machine 201 presses the repair switch 301, the repair component 3 will automatically start working. The cleaning start switch is communicatively connected to the cleaning machine 201. When the cleaning machine 201 presses the cleaning start switch, the cleaning machine 201 will start working and will then clean the cracks in the road.This solution incorporates a repair switch 301 and a cleaning start switch. When the construction worker operates the cleaning cylinder 202 to move the cleaning machine 201 towards the bottom of the mixing tank 1, the cleaning machine 201 begins working after reaching the designated height to clean the cracks in the road. Simultaneously, the cleaning machine 201 presses the repair switch 301. Since the repair switch 301 is communicatively connected to the repair component 3, the repair component 3 also starts working upon receiving the signal from the repair switch 301. This achieves the function of controlling the cleaning component 2 to work first, followed by the repair component 3. This solves the problem that existing road crack repair devices all have a cleaning component 2 and a repair component 3, which are not interconnected. Generally, the cleaning component 2 should be used first to clean the road cracks, and then the repair component 3 should be used to repair the already cleaned road cracks. However, in actual use, there are instances where construction workers neglect to activate the cleaning component 2 to clean the road cracks, and instead directly activate the repair component 3 to repair the road cracks. Such situations can easily lead to quality problems in the repair.

[0022] Further, the structure of the repair component 3 is described. The repair component 3 of this solution includes a repair cylinder 302, a scraper 303, a return spring 304, and a limiting plate 305. The bottom of the scraper 303 is parallel to the ground. The repair cylinder 302 is located on the side wall outside the mixing tank 1. The two ends of the return spring 304 are respectively connected to the side wall of the output end of the repair cylinder 302 and the scraper 303. The limiting plate 305 is located on the side wall of the mixing tank 1, directly below the scraper 303. When the cleaning machine 201 presses... After the repair switch 301 is pressed, the repair cylinder 302 begins to extend, and the scraper 303 moves towards the road surface due to the extension of the repair cylinder 302, until the top of the scraper 303 abuts against the limiting plate 305. When the cleaning machine 201 stops pressing the repair switch 301, the repair cylinder 302 begins to retract, and the scraper 303 moves away from the road surface due to the retraction of the repair cylinder 302, until the top of the scraper 303 no longer abuts against the limiting plate 305. It should be noted that the scraper 303 in this solution is used to smooth the repair fluid on the road cracks. Therefore, the bottom of the scraper 303 is at a constant height from the road surface. This setting ensures that the height of the repair fluid spread on the road surface is consistent. The limiting plate 305 is designed to ensure that the bottom of the scraper 303 is consistently at the road surface after it abuts against the limiting plate 305.

[0023] In reality, cracks in highways are often accompanied by potholes. These potholes require more repair fluid to fill; otherwise, the repaired sections of the highway will have inconsistent heights. Therefore, this solution includes a pressure sensor located at the bottom of the scraper 303. The pressure sensor detects the pressure of the repair fluid on the scraper 303. Specifically: when sufficient repair fluid is added, it comes into contact with the scraper 303, and the bottom of the scraper 303 experiences a force from the fluid, indicating that the repair fluid filling is complete and no further addition is needed. Conversely, if insufficient repair fluid is added, it does not come into contact with the scraper 303, and the bottom of the scraper 303 does not experience a force from the fluid, indicating that insufficient repair fluid has been added and further addition is required.

[0024] Furthermore, in existing highway crack repair devices, the discharge switch is also a separate, independent component. The function of the discharge switch is to control the flow of repair fluid from the mixing tank 1 to the surface of the highway crack. The discharge switch and the repair component 3 are also independent of each other. Generally, the scraper 303 of the repair component 3 needs to be lowered to a designated position before the discharge switch is opened, allowing the repair fluid to flow into the highway crack. Then, the entire device moves, and the scraper 303 smooths the repair fluid. However, in existing devices, negligence by construction personnel can lead to situations where the scraper 303 of the repair component 3 is not adjusted to the designated position before the repair fluid is controlled to flow into the highway crack. Instead, the discharge switch is directly activated, allowing the repair fluid to flow into the highway crack. In such cases, the repair fluid flows onto the highway without being smoothed. Therefore, to avoid this situation, the solution also includes a connecting component 4. A discharge hole 104 is provided on the side wall of the mixing tank 1 near the repair component 3. The discharge hole 104 communicates with the mixing space 103. The connecting component 4 includes a connecting plate 401, a sealing plate 402, and a sealing spring 403. The middle end of the connecting plate 401 is hinged to the side wall of the mixing tank 1. The sealing plate 402 is connected to one end of the connecting plate 401 and is sealed to the discharge hole 104. The output end of the repair cylinder 302 can lock or release its abutment relationship with the other end of the connecting plate 401. The two ends of the sealing spring 403... The repair cylinder 302 is connected to the sealing box and the end of the connecting plate 401 near the sealing plate 402, respectively. It should be noted that when the repair cylinder 302 extends, its output end can abut against the other end of the connecting plate 401. As the repair cylinder 302 continues to extend, it will press the other end of the connecting plate 401, causing one end of the connecting plate 401 to rotate. This causes the sealing plate 402 connected to one end of the connecting plate 401 to rotate along with the rotation of the connecting plate 401. Then, the sealing plate 402 releases its sealing relationship with the discharge hole 104, allowing the repair fluid to flow from the discharge hole 104 onto the cracks in the road.

[0025] Furthermore, it should be noted that the distance between the scraper 303 and the limiting plate 305 is the same as the distance between the output end of the repair cylinder 302 and the other end of the connecting plate 401. When the repair cylinder 302 controls the scraper 303 to abut against the limiting plate 305, the output end of the repair cylinder 302 abuts against the other end of the connecting plate 401. At this time, the repair cylinder 302 continues to extend. Due to the presence of the return spring 304, the position of the scraper 303 no longer changes, and the position of the scraper 303 has reached the designated position. It should also be noted that a telescopic component with telescopic function is provided between the scraper 303 and the repair cylinder 302. This telescopic component is set inside the return spring 304. The purpose of the telescopic component is to prevent the relative position of the scraper 303 and the repair cylinder 302 from shifting during the deformation of the return spring 304. That is, in addition to the change in height, the horizontal distance between the two will also change. The output end of the repair cylinder 302 presses down on the connecting plate 401, causing it to deflect at a certain angle. This releases the sealing plate 402 from its sealing engagement with the discharge hole 104, allowing the repair fluid to flow from the discharge hole 104 onto the cracks in the road. The sealing spring 403 helps the connecting plate 401 return to its original position, allowing the sealing plate 402 to re-seal the discharge hole 104. This design ensures that the scraper 303 is adjusted at its height before the discharge hole 104 is opened, allowing the repair fluid to flow from the discharge hole 104 onto the road. On the surface, after the repair fluid flows onto the road surface, the scraper 303 will smooth the repair fluid that has flowed onto the road surface. This solves the problem of existing road construction crack repair devices where the discharge switch is also independent. The function of the discharge switch is to control the flow of repair fluid from the mixing tank 1 to the road crack surface. The discharge switch and the repair component 3 are also independent of each other. Generally, the scraper 303 of the repair component 3 needs to be lowered to the designated position first, and then the discharge switch is opened to let the repair fluid flow into the road crack. Then the entire device moves, and the scraper 303 smooths the repair fluid. However, in existing devices, there is a possibility of negligence by the construction personnel, which may result in the scraper 303 of the repair component 3 not being adjusted to the designated position before controlling the flow of repair fluid to the road crack. Instead, the discharge switch is directly activated, allowing the repair fluid to flow into the road crack. In this case, the repair fluid flows onto the road without being smoothed.

[0026] Furthermore, this solution describes the mixing tank 1 in detail. The mixing tank 1 of this solution is also provided with a horizontal plate 105 and a vertical plate 106. The horizontal plate 105 is horizontally sealed and disposed within the mixing space 103, dividing the mixing space 103 into a discharge space. The vertical plate 106 is vertically sealed and disposed on top of the horizontal plate 105, dividing the mixing space 103 into a feeding space 1031 and an adjusting space 1032. The vertical plate 106 is sealed and connected to the mixing tank 1. The solution also includes a mixing assembly 5, which includes a mixing shaft 501 and a mixing motor 502. The mixing shaft 501 is coaxially disposed within the feeding space 1031, and the mixing motor 502 is coaxially connected to the mixing shaft 501. It should be noted that in this solution, the mixing motor 502 controls the rotation of the mixing shaft 501 to perform mixing treatment on the repair liquid.

[0027] It should be noted that, in this design, the discharge port 104 uses a sealing spring 403 to reset the connecting plate 401, thereby resetting the sealing plate 402 along with the connecting plate 401. The sealing plate 402 then re-establishes a sealing connection with the discharge port 104. However, if the flow rate of the repair fluid sprayed from the discharge port 104 is large, the sealing spring 403 may not be able to reset the sealing plate 402, thus failing to achieve a sealing fit between the sealing plate 402 and the discharge port 104. Therefore, in this design, the flow rate of the repair fluid in the discharge port 104 needs to be large when the sealing plate 402 initially releases its sealing relationship with the discharge port; while when the sealing plate 402 needs to re-seal the discharge port, the flow rate of the repair fluid needs to be small. Therefore, this solution also includes a pushing assembly 6 and a pushing rod 601. A connecting hole 1051 is provided on the horizontal plate 105, which is connected to the feeding space 1031 and the discharge space respectively. The discharge hole 104 is connected to the discharge space. The middle end of the pushing rod 601 is rotatably set in the discharge space. The pushing assembly 6 includes a telescopic rod 602, a hinge rod 603 and a hinge spring 604. The pushing rod 601 is hollow inside. The telescopic rod 602 is telescopically set at one end of the pushing rod 601. One end of the hinge rod 603 is horizontally hinged to the telescopic rod 602. The two ends of the hinge spring 604 are respectively connected to the other end of the hinge rod 603 and the pushing rod 601. The center of the other end of the hinge rod 603 is located on the rotation axis of the middle end of the pushing rod 601. Two sets of pushing assemblies are provided, and another pushing assembly is set at the other end of the pushing rod 601. It should be noted that the rotation of the push rod 601 requires the cooperation of the subsequent pressing component 7. Since the height of the push rod 601 is the same as the height of the discharge space, when the push rod 601 does not rotate, the repair fluid in the discharge space will not flow, and the flow rate of the repair fluid flowing out of the discharge hole 104 will decrease. When the push rod 601 rotates, the repair fluid in the discharge space will flow, and the flow rate of the repair fluid flowing out of the discharge hole 104 will increase. Furthermore, it should be noted that when the pressing component 7 drives the push rod 601 to rotate, it also presses the hinge rod 603, causing the telescopic rod 602 to retract into the push rod 601. At this time, the telescopic rod 602 changes from being in contact with the inner wall of the mixing tank 1 to being released from contact with the inner wall of the mixing tank 1, further increasing the passage between the discharge space and the discharge hole 104. As a result, when the push rod 601 rotates, the repair fluid in the discharge space will flow along with it, and the flow rate of the repair fluid flowing out of the discharge hole 104 will further increase.Similarly, when the pressing component 7 stops driving the push rod 601 to rotate, the pressing component 7 will also cancel its pressing engagement with the hinge rod 603, causing the telescopic rod 602 to extend out of the push rod 601 again due to the hinge spring 604. At this time, the telescopic rod 602 will re-aggregate with the inner wall of the mixing tank 1, further reducing the passage between the discharge space and the discharge hole 104. Thus, when the push rod 601 does not rotate, the repair fluid in the discharge space does not flow, and the passage between the discharge space and the discharge hole 104 is reduced, thereby reducing the flow rate of the repair fluid flowing out of the discharge hole 104.

[0028] The pressing assembly 7 is described below. The pressing assembly 7 includes a pressing motor 701, a pressing rod 702, and a connecting rod 703. The pressing motor 701 is slidably disposed within the adjustment space 1032. The pressing rod 702 is coaxially connected to the pressing motor 701 and is located directly above the middle end of the push rod 601. The hole at the middle end of the push rod 601 is an irregularly shaped hole, and the pressing rod 702 matches the hole at the middle end of the push rod 601. The two ends of the connecting rod 703 are respectively connected to the output ends of the pressing motor 701 and the repair cylinder 302. In this design, the pressing motor 701 controls the rotation of the pressing rod 702. Since the pressing motor 701 is vertically movable within the adjustment space 1032, when the pressing motor 701 moves downwards, the pressing rod 702 passes through the irregular hole at the middle of the push rod 601, causing the pressing rod 702 to push the push rod 601 to rotate. As the pressing motor 701 continues to descend, the pressing rod 702 presses against the other end of the hinge rod 603, causing the telescopic rod 602 to retract into the push rod 601. The lifting and lowering of the pressing motor 701 is achieved by the connecting rod 703. In this design, the two ends of the connecting rod 703 are connected to the pressing motor 701 and the output end of the repair cylinder 302, respectively, so that when the height of the output end of the repair cylinder 302 moves, the height of the pressing motor 701 also moves accordingly.

[0029] Furthermore, the distance between the other end of the pressing rod 702 and the hinge rod 603 in this design is the same as the distance between the output end of the repair cylinder 302 and the other end of the connecting plate 401. When the output end of the repair cylinder 302 moves to the bottom, causing it to abut against the other end of the connecting plate 401, the pressing rod 702 in this design also abuts against the other end of the hinge rod 603. When the output end of the repair cylinder 302 continues to descend, it will press against the other end of the connecting plate 401, thereby causing the sealing plate 402 to no longer seal against the opening hole. At the same time, the pressing rod 702 presses against the other end of the hinge rod 603, causing the telescopic rod 602 to retract back into the push rod 601. At this time, the telescopic rod 602 releases its abutment against the inner wall of the mixing tank 1, further... By increasing the passage between the discharge space and the discharge hole 104, the flow rate of the repair fluid flowing out of the discharge hole 104 will further increase after the sealing plate 402 releases its sealing engagement with the opening hole. Similarly, when the output end of the repair cylinder 302 moves to the top, causing the output end of the repair cylinder 302 to release its abutment engagement with the other end of the connecting plate 401, the pressing rod 702 in this scheme releases its abutment engagement with the other end of the hinge rod 603. At this time, the telescopic rod 602 extends out of the push rod 601 again, and the telescopic rod 602 abuts against the inner wall of the mixing tank 1 again, reducing the passage between the discharge space and the discharge hole 104. After the sealing plate 402 locks its sealing engagement with the opening hole, the flow rate of the repair fluid flowing out of the discharge hole 104 will further decrease.
