Description

Technical Field

[0001] This utility model relates to the field of highway crack treatment technology, and in particular to a crack treatment device for highway engineering. Background Technology

[0002] During highway construction, asphalt and gravel are mostly used to pave roads. After the highway is put into use, due to reasons such as vehicle overloading and lack of road maintenance, cracks and depressions will appear on the road surface after a long period of use. In order to ensure the normal use of the highway, special crack filling equipment is usually used to fill and repair the cracks.

[0003] A search revealed that the Chinese patent "A Highway Crack Treatment Device for Highway Engineering" (authorization announcement number "CN217203552U") involves moving a vehicle and driving a brush to clean cracks in the road surface. The cleaned debris is drawn into a dust collection box through a dust collection hood. After cleaning the cracks, the user holds the discharge pipe and aims the discharge nozzle at the crack, discharging the filler through the nozzle into the crack to fill it. Cleaning the cracks before repair improves the quality and effectiveness of the repair.

[0004] Although the aforementioned application can draw the debris cleaned by the brush into the dust collection box, some impurities will remain below the brush when the brush cleans the cracks. During the process of adsorbing the debris, the brush will block some of the impurities, resulting in poor adsorption effect and making it easy for some debris to remain in the cracks. Utility Model Content

[0005] Therefore, it is necessary to provide a crack treatment device for highway engineering to address the problem that when cleaning cracks with a brush, some impurities are placed below the brush, and during the process of adsorbing the impurities, the brush will block some of the impurities, resulting in poor adsorption effect of cleaning impurities and easy retention of some impurities in the cracks.

[0006] The device includes: a mobile cart with a grouting mechanism mounted on its top; and a cleaning mechanism comprising an electric push rod fixedly connected to one side of the mobile cart, a mounting frame fixedly connected to the telescopic end of the electric push rod, a drive assembly disposed inside the mounting frame, a brush rotatably connected to the bottom end of the mounting frame, fixed frames fixedly connected to both sides of the brush, an opening on one side of the bottom end of the fixed frame, a round tube fixedly connected to one side of the inner wall of the brush, two connecting tubes fixedly connected to the bottom end of the round tube extending through the brush, a vacuuming frame communicating with the surface of the connecting tube, and the side of the vacuuming frame away from the connecting tube extending into the fixed frame.

[0007] In one embodiment, the cleaning mechanism further includes a water tank fixedly connected to one side of the mobile vehicle. A fan is mounted on the top of the water tank, and a suction pipe is connected to the bottom of the water tank. The top of the round pipe passes through a brush and a mounting frame and is rotatably connected to the end of the suction pipe away from the water tank. This facilitates the two fixed frames to adsorb the debris being cleaned.

[0008] In one embodiment, the drive assembly includes two meshing bevel gears, the inner wall of one bevel gear being fixedly connected to the surface of the brush rotation shaft, and a servo motor being fixedly connected to the inner bottom wall of the mounting frame. The output shaft of the servo motor is fixedly connected to one end of the other bevel gear. This facilitates the reciprocating rotation of the brush during the cleaning process.

[0009] In one embodiment, the side of the suction frame away from the connecting pipe forms an angle with the vertical plane, and a filter plate is fixedly connected to the side of the suction frame away from the connecting pipe. This helps to intercept larger debris and prevents larger debris from entering the connecting pipe, the round pipe, or the suction pipe and causing jamming, thereby ensuring the stability of debris adsorption during cleaning.

[0010] In one embodiment, a sealed bearing is fixedly connected to the upper surface of the circular tube, and the outer edge of the sealed bearing is fixedly connected to the inner wall of the suction pipe. This ensures the stability of the connection between the circular tube and the suction pipe during rotation.

[0011] In one embodiment, a one-way valve is installed at the upper surface of the suction pipe, and the middle section of the suction pipe is corrugated to prevent aqueous solution from the water tank from entering the suction pipe.

[0012] In one embodiment, the bottom end of the fixing frame forms an angle with the horizontal plane, and the lowest point of the bottom end of the fixing frame is at a higher horizontal height than the lowest point of the brush. This ensures the stability of the device's operation.

[0013] In one embodiment, a guide frame is fixedly connected to the bottom end of the fixed frame, and the guide frame communicates with the opening at the bottom end of the fixed frame. This facilitates better entry of debris into the fixed frame during the adsorption process. Beneficial effects

[0014] 1. In the above-mentioned cleaning mechanism, the brush is driven to rotate reciprocally by the drive component. This helps the brush sweep debris from the cracks to both sides during the cleaning process, keeping the debris away from the cracks. At the same time, the fan creates negative pressure in the water tank, which helps the suction pipe, round pipe, two connecting pipes, and corresponding suction frames to draw in external air. This allows the two fixed frames to suck in the debris that the brush has swept to both sides, ensuring that the cleaned debris is fully incorporated into the fixed frames and guaranteeing the effective adsorption of the cleaned debris. Furthermore, as the two fixed frames rotate with the brush, they will re-adsorb the debris from the cracks after the brush has cleaned them, ensuring the cleaning effect of the cracks and preventing debris from remaining in the cracks, thus guaranteeing the filling effect of the cracks.

[0015] 2. By setting up a filter plate, it is beneficial to intercept larger debris, preventing larger debris from entering the connecting pipe, round pipe or suction pipe and causing blockage, thus ensuring the stability of debris adsorption during cleaning. Attached Figure Description

[0029] The following is combined with Figures 1-5 This invention describes a crack treatment device for highway engineering.

[0030] In one embodiment, a crack treatment device for highway engineering includes:

[0031] Mobile vehicle 100, with a crack filling mechanism 200 installed on its top;

[0032] The cleaning mechanism 300 includes an electric push rod 310 fixedly connected to one side of the mobile vehicle 100. The telescopic end of the electric push rod 310 is fixedly connected to a mounting frame 311. A drive assembly 320 is provided inside the mounting frame 311. A brush 330 is rotatably connected to the bottom end of the mounting frame 311. Fixed frames 340 are fixedly connected to both sides of the brush 330. An opening is provided on one side of the bottom end of the fixed frame 340. A round tube 350 is fixedly connected to one side of the inner wall of the brush 330. The bottom end of the round tube 350 passes through the brush 330 and is fixedly connected to two connecting tubes 351. A dust collection frame 341 is connected to the surface of the connecting tube 351. The side of the dust collection frame 341 away from the connecting tube 351 extends into the fixed frame 340.

[0033] It should be noted that the crack sealing mechanism 200 includes: a material bin for storing crack sealing material; an engine as the power source for the crack sealing machine; a transmission device to transmit the power of the engine or motor to various working parts; a heating device to heat the crack sealing material, such as asphalt or sealant, to achieve a suitable construction temperature; a delivery pump to transport the crack sealing material from the material bin to the discharge pipe; a piping system connecting the material bin, delivery pump, and discharge pipe to ensure smooth flow of the crack sealing material within the equipment; and a discharge pipe with a discharge nozzle at its end.

[0034] When using the crack filling mechanism 200 to fill cracks, the sealant in the material box is heated to a suitable temperature and then the heated sealant is transported to the discharge pipe by the delivery pump and injected into the crack through the discharge nozzle. After the sealant cools and solidifies in the crack, it fills the crack and plays a sealing role.

[0035] The operating principle of the crack filling mechanism 200 is a known technology and a known crack filling device. The technical solution of this application is the problem of crack cleaning. Therefore, the internal structure of the crack filling mechanism 200 is not labeled and described in detail. The crack filling mechanism 200 is drawn with reference to existing crack filling equipment.

[0036] In this embodiment, the two mounting frames 311 are symmetrical about the brush 330. The bristles of the brush 330 can be deformed. The brush 330 and the discharge nozzle in the filling mechanism 200 are located on the same axis. The bristles of the brush 330 can be deformed.

[0037] like Figure 2 and Figure 3 As shown, the cleaning mechanism 300 also includes a water tank 360 fixedly connected to one side of the mobile vehicle 100. A fan 361 is installed at the top of the water tank 360, and a suction pipe 362 is connected to the bottom of the water tank 360. The top of the round pipe 350 passes through the brush 330 and the mounting frame 311 and is rotatably connected to the end of the suction pipe 362 away from the water tank 360.

[0038] In this embodiment, the top of the water tank 360 is provided with a water inlet and the bottom of the water tank 360 is provided with a drain outlet. Both the water inlet and the drain outlet are equipped with sealing plugs. The water tank 360 is filled with an aqueous solution, and the horizontal height of the aqueous solution is located at two-thirds of the height of the water tank 360. The connecting pipe between the fan 361 and the water tank 360 and the aqueous solution in the water tank 360 do not affect each other.

[0039] The upper surface of the suction pipe 362 is fixedly connected to the inner top wall of the mounting frame 311 via a connecting rod. Therefore, when the mounting frame 311 moves downward, it will drive the end of the suction pipe 362 away from the water tank 360 to move downward synchronously. And when the drive tube 350 rotates, it will not drive the suction pipe 362 to rotate synchronously.

[0040] like Figure 2 and Figure 3 As shown, the drive assembly 320 includes two meshing bevel gears 321. The inner wall of one bevel gear 321 is fixedly connected to the surface of the rotating shaft of the brush 330. A servo motor 322 is fixedly connected to the inner bottom wall of the mounting frame 311. The output shaft of the servo motor 322 is fixedly connected to one end of the other bevel gear 321.

[0041] In this embodiment, the controller starts the servo motor 322, which drives another bevel gear 321 to rotate 30 degrees clockwise and 30 degrees counterclockwise. The other bevel gear 321 reciprocates between these two rotations. When the other bevel gear 321 rotates 30 degrees clockwise, it drives the brush 330 to rotate 30 degrees counterclockwise via one of the bevel gears 321. Conversely, when the other bevel gear 321 rotates 30 degrees counterclockwise, it drives the brush 330 to rotate 30 degrees clockwise via one of the bevel gears 321. (See reference...) Figure 3 The optimal effect is achieved by reciprocating within the set angle, and the specific angle of reciprocating rotation can be set according to the actual situation.

[0042] It should be noted that the center of the circular tube 350 coincides with the center of one of the bevel gears 321. Therefore, the rotation center of the brush 330 is the center of the circular tube 350.

[0043] like Figure 5 As shown, the side of the dust collection frame 341 away from the connecting pipe 351 forms an angle with the vertical plane, and a filter plate 342 is fixedly connected to the side of the dust collection frame 341 away from the connecting pipe 351.

[0044] In this embodiment, the side of the dust collection frame 341 where the filter plate 342 is installed is away from the top of the opening. Therefore, the debris intercepted by the filter plate 342 will fall to the inner bottom wall of the fixed frame 340.

[0045] like Figure 3 As shown, a sealed bearing 370 is fixedly connected to the upper surface of the round tube 350, and the outer edge of the sealed bearing 370 is fixedly connected to the inner wall of the suction tube 362.

[0046] In this embodiment, the inner edge of the sealing bearing 370 is fixedly connected to the surface of the round tube 350. Therefore, when the round tube 350 rotates, the sealing bearing 370 will seal the connection between the round tube 350 and the suction pipe 362.

[0047] like Figure 2 As shown, a one-way valve 363 is installed on the upper surface of the suction pipe 362, and the middle part of the suction pipe 362 is set as a corrugated pipe.

[0048] In this embodiment, under the action of the one-way valve 363, the suction pipe 362 can only take in air in one direction, and the aqueous solution in the water tank 360 will not enter the suction pipe 362.

[0049] like Figure 3 , Figure 4 and Figure 5As shown, the bottom of the fixed frame 340 forms an angle with the horizontal plane, and the horizontal height of the lowest point of the bottom of the fixed frame 340 is higher than the horizontal height of the lowest point of the brush 330. A guide frame 343 is fixedly connected to the bottom of the fixed frame 340, and the guide frame 343 communicates with the opening at the bottom of the fixed frame 340.

[0050] In this embodiment, the opening is located at the higher end of the bottom of the fixed frame 340, the opening of the guide frame 343 is trumpet-shaped, and the diameter of the bottom opening of the guide frame 343 is larger than the diameter of the opening.

[0051] Working Principle: The mobile cart 100 moves the cleaning mechanism 300 and the crack filling mechanism 200 to the required position. The controller activates the electric push rod 310, which pushes the mounting frame 311 downwards, causing the brush 330 and the two fixed frames 340 to move downwards synchronously. When the bottom of the brush bristles enters the crack, the electric push rod 310 is deactivated. At this time, the drive assembly 320 is activated, causing the brush 330 to rotate reciprocally between 30 degrees clockwise and 30 degrees counterclockwise. This causes the two fixed frames 340, the two suction frames 341, and the two connecting pipes 351 to rotate synchronously. During rotation, the brush 330 sweeps debris from the crack to both sides. Simultaneously, the controller activates the fan 361, expelling air from the water tank 360 to create negative pressure. This pressure causes the suction pipe 362, the round pipe 350, the two connecting pipes 351, and the corresponding suction frames 341 to... The fixed frame 340 sucks in external air and cleaned debris. At the same time, as the brush 330 rotates and cleans, the debris cleaned by the brush 330 is adsorbed by the fixed frame 340 in the direction of the brush 330's rotation. Simultaneously, another fixed frame 340 follows the rotation of the brush 330 to adsorb and clean the debris in the cracks again. When the cleaned debris is adsorbed into the fixed frame 340, the filter plate 342 intercepts larger debris and falls to the inner bottom wall of the fixed frame 340 under its own gravity. Smaller debris will follow the air through the suction frame 341, connecting pipe 351, round pipe 350, and suction pipe 362 into the water tank 360 to mix with the aqueous solution, thereby reducing the dust content. While the cleaning mechanism 300 is cleaning, it pulls the moving cart 100 to move. At the same time, the crack filling mechanism 200 is started, so that the discharge nozzle in the crack filling mechanism 200 injects the filling material into the cleaned cracks to fill them.

[0052] It should be noted that the electric linear actuator 310 and servo motor 322 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electric linear actuator 310 and servo motor 322 can be powered by the built-in power supply or by AC power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
