Description

Technical Field

[0001] This invention relates to the field of highway crack treatment technology, and more specifically to a highway crack treatment device for highway engineering. Background Technology

[0002] Highway crack repair equipment used in highway engineering is a type of engineering machinery specifically designed to repair cracks in highway pavements (such as asphalt pavements and cement concrete pavements). This equipment employs a series of standardized operating procedures (such as grooving, cleaning, and crack sealing) to specifically treat cracks, preventing moisture from seeping into the roadbed and further crack expansion, thereby extending the service life of the highway and ensuring driving safety. This type of equipment is typically designed around a complete crack repair process, covering all stages from crack pretreatment to final sealing. It features high professionalism, highly targeted operation, and stable operating efficiency, and can adapt to the needs of repairing highway cracks of different types and scales.

[0003] Most highway crack repair equipment used in highway engineering employs asphalt grouting and surface treatment to repair the road surface. The asphalt needs to be continuously stirred in a mixing tank. After the road crack repair is completed, the asphalt on the inner wall of the mixing tank is difficult to clean. This is because asphalt is a high-molecular colloidal mixture that is semi-solid at room temperature and has extremely strong viscosity, making it difficult to clean. In existing technologies, a scraper device is added to scrape off the asphalt adhering to the side wall of the mixing tank while stirring and mixing the asphalt in the tank. However, asphalt also adheres to the surface of the scraper, forming an adhesive layer that affects subsequent use. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a highway crack treatment device for highway engineering, so as to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: a highway crack treatment device for highway engineering, comprising a base plate, a circular hole on the left side of the upper surface of the base plate, a handle fixedly connected to the left side of the base plate, and casters symmetrically rotatably connected to the lower surface of the base plate. Multiple fixing sleeves are fixedly connected to the upper surface of the base plate next to the circular hole. A T-shaped column is slidably connected to the inner wall of each fixing sleeve away from the base plate. A support spring is fixedly connected to the lower end of each T-shaped column.

[0007] Preferably, a rectangular groove is formed on the top surface of the mixing tank between two mounting holes. A stop block is symmetrically slidably connected to the groove wall of the rectangular groove. A first rack is fixedly connected to the surface of the stop block. A transmission gear is meshed between the two first racks. A cylinder is fixedly connected above the transmission gear. The cylinder is rotatably connected to the top of the mixing tank. A vertical groove and a spiral groove are formed on the surface of the cylinder. The spiral groove and the vertical groove are connected. A protrusion is fitted on the groove wall of the spiral groove. A connecting sleeve is fitted on the outer side of the cylinder. The protrusion is fixedly connected to the inner wall of the connecting sleeve. A first L-shaped column is fixedly connected to the upper end of the connecting sleeve. The lower end of the first L-shaped column is fixedly connected to the bottom plate.

[0008] Preferably, a pressure plate is fitted onto the inner wall of the water storage tank. A first spring, evenly distributed in a ring, is fixedly connected to the upper surface of the pressure plate. A circular plate is fixedly connected to the upper end of a plurality of first springs. A movable sleeve is fixedly connected to the upper surface of the circular plate. A vertical column is slidably connected to the inner wall of the movable sleeve. A second L-shaped column is fixedly connected to the upper end of the vertical column. The end of the second L-shaped column away from the circular plate is fixedly connected to the mixing tank. A water outlet is provided at the bottom end of the surface of the water storage tank, and the water outlet is connected to a third connecting pipe.

[0009] Preferably, the initial state of the support spring is a compressed state.

[0010] Preferably, a horizontal column is symmetrically fixedly connected to one end of the vertical column near the circular plate. A column groove is opened on the surface of the horizontal column. A slider is slidably connected to the groove wall. A second spring is fixedly connected to the surface of the slider. A limit plate is slidably connected to the surface of the horizontal column. The limit plate is fixedly connected to the slider. Limit blocks are fixedly connected at equal intervals to the outside of the movable sleeve. Four of the limit blocks are installed in cooperation with the limit plate.

[0011] Preferably, a first motor is fixedly connected to the top surface of the mixing tank, a stirring column is fixedly connected to the output end of the first motor, scrapers are symmetrically fixedly connected to one end of the stirring column near the top of the mixing tank, both scrapers are installed in conjunction with the inner wall of the mixing tank, and a heating plate is fixedly connected to the outside of the mixing tank.

[0012] Preferably, a strip-shaped groove is formed on the end face of the first rack away from the stop block, and a second rack is slidably connected to the groove wall of the strip-shaped groove. A third spring is fixedly connected to the end of the second rack near the first rack.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. The present invention, through the configuration of a water storage tank, a first connecting pipe, a second connecting pipe, a third connecting pipe, and a nozzle, enables water in the water storage tank to be sprayed out from the nozzle through the water outlet, the first connecting pipe, the second connecting pipe, and the third connecting pipe after the asphalt is discharged from the mixing tank, so as to promptly wash the surface of the scraper and prevent the formation of an asphalt adhesion layer on the scraper surface, thus avoiding affecting subsequent use.

[0015] 2. This invention, through the design of horizontal columns, column grooves, sliders, limiting plates, and limiting blocks, allows the circular plate and pressure plate to move downwards during the initial adjustment, pressurizing the water in the storage tank into the mixing tank. The mixing tank then returns to its initial state under the elastic force of the supporting spring. Relative movement occurs between the limiting plate and multiple limiting blocks, and between the movable sleeve and the vertical column. This means that even after asphalt is added back into the mixing tank and the road crack treatment is completed, water from the storage tank can still be regulated to enter the mixing tank to wash the surface of the scraper inside. In actual use, this extends the overall operating time of the device, eliminating the need to replenish water to the storage tank after the asphalt in the mixing tank is depleted, thus shortening the time required for road crack treatment and improving the efficiency of road crack treatment.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The highway crack treatment device for highway engineering involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1 to 10 This invention provides a highway crack treatment device for highway engineering, including a base plate 1, a circular hole 2 on the left side of the upper surface of the base plate 1, a handle 3 fixedly connected to the left side of the base plate 1, and casters 4 symmetrically rotatably connected to the lower surface of the base plate 1. Multiple fixing sleeves 5 are fixedly connected to the upper surface of the base plate 1 next to the circular hole 2. T-shaped columns 6 are slidably connected to the inner wall of the multiple fixing sleeves 5 away from the base plate 1. A support spring 7 is fixedly connected to the lower end of the T-shaped column 6. A mixing tank 8 is fixedly connected to the upper end of the multiple T-shaped columns 6. Mounting holes 9 are symmetrically opened on the top upper surface of the mixing tank 8. A nozzle 10 is fixedly connected to the wall of the mounting hole 9. A first connecting pipe 11 and a second connecting pipe 12 are fixedly connected above the two mounting holes 9 respectively. A third connecting pipe 13 is fixedly connected to the end of the first connecting pipe 11 and the second connecting pipe 12 away from the mixing tank 8. A water storage tank 14 is fixedly connected to the end of the third connecting pipe 13 away from the first connecting pipe 11 and the second connecting pipe 12.

[0029] A first motor 36 is fixedly connected to the top surface of the mixing tank 8. A stirring column 37 is fixedly connected to the output end of the first motor 36. Scrapers 38 are symmetrically fixedly connected to one end of the surface of the stirring column 37 near the top of the mixing tank 8. Both scrapers 38 are installed in conjunction with the inner wall of the mixing tank 8. A heating plate is fixedly connected to the outer side of the mixing tank 8.

[0030] It should be noted that the mixing column 37 and scraper 38 are designed to mix the asphalt placed in the mixing tank 8 and scrape the inner wall of the mixing tank 8. The heating plate is powered on to maintain the temperature inside the mixing tank 8.

[0031] The mixing tank 8 has a feed inlet 15 on its top surface and a discharge outlet 16 on its bottom surface. A discharge valve is installed on the surface of the discharge outlet 16.

[0032] A rectangular groove 17 is formed on the top surface of the mixing tank 8 between two mounting holes 9. A stop block 18 is symmetrically slidably connected to the wall of the rectangular groove 17. A first rack 19 is fixedly connected to the surface of the stop block 18. A transmission gear 20 meshes between the two first racks 19. A cylinder 21 is fixedly connected above the transmission gear 20 and is rotatably connected to the top of the mixing tank 8. A vertical groove 22 and a spiral groove 23 are formed on the surface of the cylinder 21, and the spiral groove 23 and the vertical groove 22 are connected. The spiral groove 23 has a protrusion 24 installed on its groove wall. A connecting sleeve 25 is fitted on the outer side of the cylinder 21. The protrusion 24 is fixedly connected to the inner wall of the connecting sleeve 25. A first L-shaped column is fixedly connected to the upper end of the connecting sleeve 25. The lower end of the first L-shaped column is fixedly connected to the base plate 1. A strip groove 40 is opened on the end face of the first rack 19 away from the stop block 18. A second rack 39 is slidably connected to the groove wall of the strip groove 40. A third spring is fixedly connected to the end of the second rack 39 near the first rack 19.

[0033] It should be noted that during the process of adding asphalt into the mixing tank 8, the mixing tank 8 moves towards the bottom plate 1, causing relative movement between the connecting sleeve 25 and the cylinder 21, and between the protrusion 24 and the spiral groove 23, which in turn drives the cylinder 21 to rotate. The transmission gear 20 rotates along with the cylinder 21, thereby adjusting the stop block 18 to move and block the mounting hole 9. Relative movement occurs between the second rack 39 and the strip groove 40, and the third spring is compressed. When asphalt is added, the stop block 18 blocks the mounting hole 9. After the asphalt in the mixing tank 8 is consumed, the stop block 18 is removed from the mounting hole 9, and water is sprayed out from the nozzle 10. After the asphalt in the mixing tank 8 is consumed, the interior can be cleaned immediately to prevent the formation of an asphalt adhesion layer on the surface of the scraper 38, which would affect subsequent use.

[0034] A pressure plate 26 is fitted to the inner wall of the water storage tank 14. A first spring 27, which is evenly distributed in a ring, is fixedly connected to the upper surface of the pressure plate 26. A circular plate 28 is fixedly connected to the upper end of the multiple first springs 27. A movable sleeve 29 is fixedly connected to the upper surface of the circular plate 28. A vertical column 30 is slidably connected to the inner wall of the movable sleeve 29. A second L-shaped column is fixedly connected to the upper end of the vertical column 30. The end of the second L-shaped column away from the circular plate 28 is fixedly connected to the mixing tank 8. A water outlet is opened at the end of the surface of the water storage tank 14 near the bottom. The water outlet is connected to the third connecting pipe 13.

[0035] It should be noted that during the process of the circular plate 28 being adjusted to move closer to the base plate 1, the first spring 27 is compressed, and the resulting reaction force acts on the surface of the pressure plate 26, ensuring that there is sufficient force so that the water in the water tank 14 can pass smoothly through the third connecting pipe 13, the second connecting pipe 12 and the first connecting pipe 11, and be sprayed out by the nozzle 10 to rinse the surface of the scraper 38. The scraper 38 is driven to rotate by the first motor 36 to ensure the rinsing effect.

[0036] The initial state of the support spring 7 is that it is compressed;

[0037] It should be noted that the reaction force generated by the compression of the support spring 7 acts on the surface of the T-shaped column 6, thus supporting the mixing tank 8.

[0038] Based on the above embodiments, after adding asphalt to the mixing tank 8 again in this embodiment, after the road crack treatment is completed, the water in the water storage tank 14 can still be adjusted to enter the mixing tank 8. In actual use, it can extend the service time of the entire device. There is no need to add water to the water storage tank 14 after the asphalt in the mixing tank 8 is consumed, thereby shortening the time required for road crack treatment and improving the efficiency of road crack treatment.

[0039] A horizontal column 31 is symmetrically fixedly connected to one end of the vertical column 30 near the circular plate 28. A column groove 32 is opened on the surface of the horizontal column 31. A slider 33 is slidably connected to the groove wall of the column groove 32. A second spring is fixedly connected to the surface of the slider 33. A limit plate 34 is slidably connected to the surface of the horizontal column 31. The limit plate 34 is fixedly connected to the slider 33. Limit blocks 35 are fixedly connected at equal intervals on the outer side of the movable sleeve 29. Four limit blocks 35 are installed in cooperation with the limit plate 34.

[0040] It should be noted that as the asphalt in the mixing tank 8 is consumed, under the elastic force of the supporting spring 7, the mixing tank 8 moves away from the bottom plate 1. Since the water in the water storage tank 14 has been consumed, the vertical column 30 and the second L-shaped column move together with the mixing tank 8, and the horizontal column 31 moves together with the vertical column 30. The limiting plate 34 and the limiting block 35 move relative to each other, the second spring is further stretched, and the vertical column 30 moves relative to the movable sleeve 29 until the T-shaped column 6 moves to the top of the fixed sleeve 5. When asphalt is added to the mixing tank 8 again, the limiting plate 34 and the limiting block 35 cooperate to drive the circular plate 28 and the pressure plate 26 to move downward again, pressing the water in the water storage tank 14 into the mixing tank 8.

[0041] It should be noted that the asphalt in the mixing tank 8 can be discharged from the discharge port 16 and connected to the asphalt spray gun through a pipe, which facilitates the treatment of road cracks.

[0042] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
