DETAILED DESCRIPTION

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figures 1-10 As shown, a highway crack treatment device for highway engineering includes a device base 1. Fixed support legs 11 are located at the four corners of the lower end of the device base 1. The device base 1 and the multiple fixed support legs 11 are all fixedly connected. Universal casters 12 are located at the lower end of each fixed support leg 11, and the connection between the fixed support legs 11 and the universal casters 12 is fixed. A vacuum cleaner 13 is located at the front of the lower end of the device base 1, and the connection between the vacuum cleaner 13 and the device base 1 is fixed. The vacuum cleaner 13 is used to suck dust and debris from the cracks into a dust collection box 14 to prevent the asphalt from overflowing after the cracks are filled with asphalt. The device cannot fit well against the crack wall, resulting in poor filling effect. The upper end of the device base 1 is equipped with a dust collection box 14 that is compatible with the vacuum cleaner 13. The connection between the device base 1 and the vacuum cleaner 13 is fixed. The rear side of the upper end of the device base 1 is equipped with an asphalt storage tank 15. The connection between the asphalt storage tank 15 and the device base 1 is fixed. The asphalt storage tank 15 is used to hold asphalt. When in working condition, the filling port of the asphalt storage tank 15 is closed. The rear side of the lower end of the device base 1 is equipped with a filling device 2. The connection between the device base 1 and the filling device 2 is fixed.

[0034] The filling device 2 includes a first discharge pipe 21. An installation rod connects the first discharge pipe 21 to the device base 1. The installation rod is fixedly connected to both the first discharge pipe 21 and the device base 1. The installation rod increases the distance between the first discharge pipe 21 and the device base 1, facilitating the placement of the sealing rod 3. A first inlet pipe 22, communicating with the inside of the asphalt storage tank 15, is provided on the upper part of the outer surface of the first discharge pipe 21. The first inlet pipe 22 is fixedly connected to both the asphalt storage tank 15 and the first discharge pipe 21. The first inlet pipe 22 transports asphalt from the asphalt storage tank 15 to the first discharge pipe 21. The lower end of 21 is provided with a second discharge pipe 23. The connection between the second discharge pipe 23 and the first discharge pipe 21 is fixed. The second discharge pipe 23 is used to release asphalt. In the working state, the bottom surface of the second discharge pipe 23 is in contact with the ground, which will allow the asphalt to flow into the crack and prevent the asphalt from flowing to other places, thus causing material waste. The rear part of the outer surface of the first discharge pipe 21 and the second discharge pipe 23 are connected to a second inlet pipe 24. The connection between the second inlet pipe 24 and the first discharge pipe 21 and the second discharge pipe 23 is fixed. The second inlet pipe 24 is used to transfer the asphalt in the first discharge pipe 21 to the second discharge pipe 23.

[0035] Specifically, the upper end of the first discharge pipe 21 is provided with a sealing rod 3, and the connection relationship between the sealing rod 3 and the first discharge pipe 21 is movable connection. The sealing rod 3 is used for sealing the top of the first discharge pipe 21 to prevent asphalt from flowing out of the top of the first discharge pipe 21, thereby causing waste of materials. The first discharge pipe 21 and the inner cavity of the second discharge pipe 23 are provided with a driving device 4 in common. The connection relationship between the driving device 4 and the first discharge pipe 21 and the second discharge pipe 23 is sliding connection. The driving device 4 is used for sealing the second feeding pipe 24 and can adjust the amount of asphalt flowing from the first discharge pipe 21 into the second discharge pipe 23 according to the amount of asphalt remaining in the second discharge pipe 23, so that a sufficient amount of asphalt can be stored in the second discharge pipe 23 to prevent the crack filling device 2 from being unable to inject a sufficient amount of asphalt after the crack becomes wider or deeper, thereby affecting the stability of the device during operation. A plurality of ventilation holes 25 are arranged in an annular array on the upper part of the outer surface of the second discharge pipe 23. The ventilation holes 25 are used for exhausting air in the second discharge pipe 23, thereby increasing the stability of the device during operation. A plurality of vibration devices 6 are arranged in an annular array on the lower part of the outer surface of the second feeding pipe 24. The connection relationship between the second feeding pipe 24 and the plurality of vibration devices 6 is fixed connection.

[0036] Specifically, the upper part of the first discharge pipe 21 is in communication with the outside, so that the asphalt in the first discharge pipe 21 is always submerged at the connection between the first feeding pipe 22 and the first discharge pipe 21, thereby storing a certain amount of asphalt in the first discharge pipe 21 to provide the second discharge pipe 23 and ensure that a certain amount of asphalt can be stored in the second discharge pipe 23. The lower part of the second discharge pipe 23 is in communication with the outside, which facilitates the flow of asphalt into the crack. The connection between the first feeding pipe 22 and the first discharge pipe 21 is located above and to the front of the connection between the second feeding pipe 24 and the first discharge pipe 21. The ventilation holes 25 are located above the connection between the second feeding pipe 24 and the second discharge pipe 23, so that the asphalt in the first discharge pipe 21 can flow into the second discharge pipe 23 through the second feeding pipe 24.

[0037] Further, to seal the part where the upper part of the first discharge pipe 21 is in communication with the outside, as shown in Figures 3-8 The sealing rod 3 includes a first rotating screw 31. The connection relationship between the first rotating screw 31 and the first discharge pipe 21 is movable connection. When the first rotating screw 31 is threadedly connected with the first discharge pipe 21, the upper part of the first discharge pipe 21 is not in communication with the outside. The upper end of the first rotating screw 31 is provided with a first limiting block 32. The connection relationship between the first limiting block 32 and the first rotating screw 31 is fixed connection. The first limiting block 32 is used for mounting the first mounting block 33. The lower end of the first limiting block 32 is provided with a first mounting block 33. The connection relationship between the first limiting block 32 and the first mounting block 33 is rotary connection. When the first limiting block 32 rotates, the first return spring 34 will also rotate, thereby affecting the stability of the device during operation.

[0038] Specifically, a first return spring 34 is provided between the first mounting block 33 and the first discharge pipe 21. The connection between the first return spring 34 and the first mounting block 33 and the first discharge pipe 21 is a fixed connection. The first return spring 34 cooperates with the first mounting block 33 and the first discharge pipe 21 so that when the first rotating screw 31 is not threadedly connected to the first discharge pipe 21, there is space between the first rotating screw 31 and the first discharge pipe 21, and the first discharge pipe 21 is connected to the outside. An extension rod 35 is provided at the lower end of the first rotating screw 31. The connection between the extension rod 35 and the first rotating screw 31 is a rotatable connection, and the connection between the extension rod 35 and the sealing pipe 41 is a sliding connection. The extension rod 35 cooperates with the limiting device 5 so that when the first rotating screw 31 moves downward, the active device 4 moves upward. The bottom surface of the inner cavity of the first discharge pipe 21 is provided with a limiting device 5 that is compatible with the sealing rod 3 and the active device 4.

[0039] Furthermore, in order to ensure that a certain amount of asphalt can be stored in the second discharge pipe 23, such as... Figures 4-8 As shown, the active device 4 includes a sealing pipe 41 located inside the first discharge pipe 21. The sealing pipe 41 and the first discharge pipe 21 are slidably connected. The sealing pipe 41 is used to seal the connection between the second feed pipe 24 and the second discharge pipe 23, preventing asphalt in the first discharge pipe 21 from flowing into the second feed pipe 24. A first sliding rod 42 is provided at the lower end of the sealing pipe 41. The first sliding rod 42 and the sealing pipe 41 are fixedly connected. A buoyancy pipe 43 is provided at the lower end of the first sliding rod 42. The buoyancy pipe 43 and the first sliding rod 42 are fixedly connected. When the asphalt liquid surface in the second discharge pipe 23 comes into contact with the buoyancy pipe 43, the buoyancy pipe 43 floats upward, causing the sealing pipe 41 to slide upward, thereby adjusting the flow rate of asphalt into the second discharge pipe 23 and further ensuring that the volume of asphalt in the second discharge pipe 23 is always within a certain range. A second return spring 44 is provided between the top surface of the inner cavity of the buoyancy pipe 43 and the second discharge pipe 24. The buoyancy pipe 43 and the second return spring 44 are located inside the second discharge pipe 23, and the connection between the second return spring 44 and the buoyancy pipe 43 and the second discharge pipe 23 is a fixed connection.

[0040] Specifically, the limiting device 5 includes two support rods 51, the connection relationship between the two support rods 51 and the first discharge pipe 21 is fixed connection, the two support rods 51 are used for mounting the third mounting block 52, the upper ends of the two support rods 51 are provided with the third mounting block 52 in common, and the third mounting block 52 is located in the sealing pipe 41. The connection relationship between the two support rods 51 and the third mounting block 52 is fixed connection, the upper end of the third mounting block 52 is provided with two U-shaped grooves 53, the lower end of the extension rod 35 is provided with two first push rods 54 matched with the U-shaped grooves 53, the connection relationship between the extension rod 35 and the two first push rods 54 is fixed connection, the connection relationship between the first push rod 54 and the U-shaped groove 53 is sliding connection, a plurality of sliding balls 55 are arranged in the U-shaped groove 53, the connection relationship between the uppermost sliding ball 55 and the first push rod 54 is fixed connection, the outer surface of the sliding ball 55 away from the first push rod 54 is provided with a second push rod 56 at the upper part, and the second push rod 56 is located in the vertical part of the U-shaped groove 53. The second push rod 56 cooperates with the sliding ball 55, so that when the extension rod 35 moves downward, the second push rod 56 pushes the sealing pipe 41 to move upward, so that the sealing pipe 41 seals the connection between the first discharge pipe 21 and the second feeding pipe 24.

[0041] The specific implementation of the embodiment is that: in use, first, the first rotating screw 31 is rotated, so that the sealing pipe 41 seals the connection between the first discharge pipe 21 and the second feeding pipe 24, asphalt is added into the asphalt storage barrel 15, the device is pushed to the position to be treated, then the first rotating screw 31 is rotated to make the sealing pipe 41 not seal the connection between the first discharge pipe 21 and the second feeding pipe 24, the asphalt flows into the crack through the first feeding pipe 22 and the second discharge pipe 23 to fill the crack, the vibration device 6 vibrates the ground, so that the asphalt can better adhere to the inner wall of the crack. When the asphalt liquid level in the second discharge pipe 23 contacts the buoyancy pipe 43, the buoyancy pipe 43 floats upward, so that the sealing pipe 41 slides upward, so as to adjust the flow rate of the asphalt flowing into the second discharge pipe 23, further ensure that the volume of the asphalt in the second discharge pipe 23 is always in a value range, prevent the crack from widening or deepening after the filling device 2 cannot inject sufficient asphalt, thereby affecting the stability of the device during operation, then the device is pushed forward to move, thereby completing the treatment of the entire crack. During the movement of the device, the buoyancy pipe 43 cooperates with the sealing pipe 41, so that a certain amount of asphalt can be stored in the second discharge pipe 23, thereby ensuring the flow rate of the asphalt flowing into the crack, and increasing the stability of the device during operation.

[0042] When the crack is filled, the first rotating screw 31 is rotated to move the extension rod 35 downward, the second push rod 56 cooperates with the sliding ball 55, and the second push rod 56 pushes the sealing tube 41 upward when the extension rod 35 moves downward, so that the sealing tube 41 seals the connection between the first discharge tube 21 and the second feeding tube 24, so that the asphalt in the asphalt storage barrel 15 cannot flow out.
