Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt pavement maintenance technology, and more specifically, to a maintenance device for asphalt pavement. Background Technology
[0002] Asphalt pavement maintenance is an extremely important part of road maintenance. Maintenance work can ensure that the road surface is smooth, free of potholes and cracks, reduce the bumps and swaying of vehicles when driving, improve driving stability, and good road conditions can also reduce the risk of traffic accidents caused by road damage, thus ensuring driving safety.
[0003] Cracks are one of the most common defects in asphalt pavements during maintenance. They typically manifest as small or large cracks, and can even form a network of cracks. Cracks not only affect the aesthetics of the pavement, but more importantly, they reduce its strength and stability, leading to other defects.
[0004] However, during the crack repair process, since the cracks vary in size and width, using a construction team would require a large amount of manpower. Therefore, in the case of single-person construction, compared to traditional equipment, the worker cannot effectively control the amount of asphalt material used. Excessive use of asphalt material will lead to waste. Therefore, it is necessary to improve and optimize the asphalt wood surface curing device. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a maintenance device for asphalt pavement, which has the advantage of manually releasing asphalt raw materials and preventing waste of raw materials.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a maintenance device for asphalt pavement, comprising a main support plate, a storage structure on the upper surface of the main support plate, a material dispensing assembly rotatably connected to the lower part of the storage structure, a gear fixedly connected to the front end of the material dispensing assembly, a sliding groove fixedly connected to the upper surface of the main support plate, a sliding rack movably connected inside the sliding groove, the sliding rack meshing with the gear, a first fixing rod fixedly connected to the upper right part of the sliding rack, a fixing column fixedly connected to the upper right end of the main support plate, a first helical gear rotatably connected to the upper part of the fixing column, a spring fixedly connected to the upper surface of the main support plate, a pressing disc fixedly connected to the upper part of the spring, the pressing disc movably connected to the fixing column, a second fixing rod fixedly connected to the upper left front end of the first helical gear, a hinge rod hinged between the second fixing rod and the first fixing rod, a fixing frame fixedly connected to the upper right side of the main support plate, and a driving structure provided inside the second fixing rod.
[0007] As a preferred technical solution of this utility model: a motor is fixedly connected to the upper surface of the fixed frame, a second helical gear is fixedly connected to the output shaft of the motor, a first rotating shaft is rotatably connected inside the fixed frame, a third helical gear is fixedly connected to the lower part of the first rotating shaft, the third helical gear meshes with the second helical gear, a stirring rod is rotatably connected to the upper part of the storage structure, a first belt is connected between the upper part of the stirring rod and the upper part of the first rotating shaft, and a stirring plate is fixedly connected to the surface of the stirring rod.
[0008] As a preferred technical solution of this utility model: the driving structure includes a second rotating shaft rotatably connected inside the fixed frame, a fourth helical gear fixedly connected to the left side of the motor, the fourth helical gear meshing with the first helical gear, a crank handle rotatably connected to the upper right surface of the fixed frame, and a second belt drivingly connecting the left side of the crank handle to the second rotating shaft.
[0009] As a preferred technical solution of this utility model: the storage structure includes a fixed bracket fixedly connected to the upper surface of the main support plate, a storage cylinder fixedly connected inside the fixed bracket, a cylinder cover detachably installed on the upper surface of the storage cylinder, and a discharge port fixedly connected to the lower part of the storage cylinder.
[0010] As a preferred technical solution of this utility model: the upper inner surface of the storage cylinder is rotatably connected to the upper outer surface of the first rotating shaft, and the inside of the discharge port is rotatably connected to the discharge assembly.
[0011] As a preferred technical solution of this utility model: a support block is fixedly connected to the upper surface of the main support plate, and the support block is rotatably connected to the feeding assembly.
[0012] As a preferred embodiment of this utility model: a pusher is fixedly connected to the upper right surface of the main support plate, and a wheel is fixedly connected to the lower surface of the main support plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model drives the rotation of the first helical gear through a drive structure. Since the second fixed rod is located on the outer periphery of the upper surface of the first helical gear, it drives the sliding rack to slide along the inside of the groove under the hinge of the hinge rod. The sliding rack and the gear mesh with each other, thereby realizing the rotation of the discharge assembly inside the discharge port. Since the rotation angle can control the flow rate of the asphalt raw material and the opening and closing of the asphalt raw material outlet, and since the second fixed rod, the first fixed rod and the sliding rack are not on the same horizontal line, when the crank handle is rotated to a certain angle, the outer left end of the sliding rack fits against the inner left end of the groove, so that the operator can clearly feel the closing of the discharge assembly on the asphalt raw material, thereby preventing the waste of raw materials.
[0015] 2. This utility model uses a motor to drive the rotation of the second helical gear, and the third helical gear meshes with the second helical gear, which in turn drives the first rotating shaft to rotate. Under the drive of the first belt, the stirring plate fixedly connected to the surface of the stirring rod rotates. The stirring plate is in contact with the inner wall of the storage cylinder, so that the asphalt raw material adhering to the inner wall of the storage cylinder is scraped off, thereby making the asphalt raw material more thoroughly mixed and increasing the utilization rate of the asphalt raw material.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] like Figures 1 to 5As shown, this utility model provides a maintenance device for asphalt pavement, including a main support plate 1. A storage structure is provided on the upper surface of the main support plate 1. A material dispensing component 2 is rotatably connected to the lower part of the storage structure. A gear 3 is fixedly connected to the front end of the material dispensing component 2. A sliding groove 4 is fixedly connected to the upper surface of the main support plate 1. A sliding rack 5 is movably connected inside the sliding groove 4. The sliding rack 5 meshes with the gear 3. A first fixing rod 6 is fixedly connected to the upper right part of the sliding rack 5. A fixing column 7 is fixedly connected to the upper right end of the main support plate 1. A first helical gear 8 is rotatably connected to the upper part of the fixing column 7. A spring 9 is fixedly connected to the upper surface of the main support plate 1. A pressing disc 10 is fixedly connected to the upper part of the spring 9. The pressing disc 10 is movably connected to the fixing column 7. A second fixing rod 11 is fixedly connected to the upper left front end of the first helical gear 8. A hinge rod 12 is hinged between the second fixing rod 11 and the first fixing rod 6. A fixing frame 13 is fixedly connected to the upper right part of the main support plate 1. A driving structure is provided inside the second fixing rod 11.
[0024] When asphalt pavement maintenance is required, the worker manually turns the right end of the crank handle 23. Due to the transmission effect of the second belt 24, the second rotating shaft 21 rotates inside the fixed frame 13, thereby driving the first helical gear 8, which meshes with the fourth helical gear 22, to rotate. Since the second fixed rod 11, which is fixedly connected to the surface of the first helical gear 8, is hinged to the first fixed rod 6 through the hinge rod 12, the sliding rack 5 moves left and right inside the slide groove 4. The surfaces of the gear 3 and the sliding rack 5 mesh with each other, thereby driving the material discharge assembly 2 to rotate inside the discharge port 28. When it rotates to a certain angle, the asphalt raw material inside the storage cylinder 26 will flow out from the lower part of the discharge port 28 and reach the ground. Since the spring 9 is in a compressed state, it pushes the extrusion plate 10 upward, so that the lower surface of the first helical gear 8 has a certain sliding friction with the extrusion plate 10. Therefore, the first helical gear 8 will not rotate when the worker does not apply force to the crank handle 23.
[0025] The upper surface of the fixed frame 13 is fixedly connected to a motor 14, the output shaft of the motor 14 is fixedly connected to a second helical gear 15, the inside of the fixed frame 13 is rotatably connected to a first rotating shaft 16, the lower part of the first rotating shaft 16 is fixedly connected to a third helical gear 17, the third helical gear 17 and the second helical gear 15 mesh with each other, the upper part of the storage structure is rotatably connected to a stirring rod 18, the upper part of the stirring rod 18 is connected to the upper part of the first rotating shaft 16 by a first belt 19, and the surface of the stirring rod 18 is fixedly connected to a stirring plate 20.
[0026] After the storage cylinder 26 is filled with asphalt, the motor 14 is started. The output shaft of the motor 14 rotates, which drives the second helical gear 15 to rotate. Since the third helical gear 17 meshes with the second helical gear 15, it drives the first rotating shaft 16 to rotate inside the fixed frame 13. Under the transmission action of the first belt 19, it drives the stirring rod 18 to rotate. The outer side of the stirring plate 20, which is fixedly connected to the surface of the stirring rod 18, is in contact with the inner wall of the storage cylinder 26, thereby driving the stirring of the asphalt raw material inside the storage cylinder 26 and causing the asphalt raw material adhering to the inner wall of the storage cylinder 26 to be scraped off.
[0027] The drive structure includes a second rotating shaft 21 rotatably connected inside the fixed frame 13, a fourth helical gear 22 fixedly connected to the left side of the motor 14, the fourth helical gear 22 meshing with the first helical gear 8, a crank handle 23 rotatably connected to the upper right surface of the fixed frame 13, and a second belt 24 drivingly connected between the left side of the crank handle 23 and the second rotating shaft 21.
[0028] The handle 23 is rotatably connected to the right surface of the fixed frame 13. Therefore, turning the right end of the handle 23 drives the transmission of the second belt 24, thereby driving the second shaft 21 to rotate. Due to the meshing of the fourth helical gear 22 with the first helical gear 8, the first helical gear 8 is given a driving force to rotate.
[0029] The storage structure includes a fixed bracket 25 fixedly connected to the upper surface of the main support plate 1, a storage cylinder 26 fixedly connected inside the fixed bracket 25, a cylinder cover 27 detachably installed on the upper surface of the storage cylinder 26, and a discharge port 28 fixedly connected to the lower part of the storage cylinder 26.
[0030] By opening the cylinder cover 27, asphalt raw materials enter and exit through the cylinder cover 27. The storage cylinder 26 is used to temporarily store the asphalt raw materials, which then flow out from the discharge port 28 to the road surface that needs maintenance.
[0031] The upper inner surface of the storage cylinder 26 is rotatably connected to the upper outer surface of the first rotating shaft 16, and the inside of the discharge port 28 is rotatably connected to the discharge assembly 2.
[0032] The first rotating shaft 16 rotates on the upper part of the storage cylinder 26, providing support force to the first rotating shaft 16. At the same time, the discharge assembly 2 rotates inside the discharge port 28, thereby realizing the discharge and closure of the asphalt raw materials.
[0033] Among them, a support block 29 is fixedly connected to the upper surface of the main support plate 1, and the support block 29 is rotatably connected to the feeding assembly 2.
[0034] The support block 29 provides support to the rear end of the feeding assembly 2, so that the feeding assembly 2 can be disassembled and installed inside the discharge port 28.
[0035] Among them, a pusher 30 is fixedly connected to the upper right surface of the main support plate 1, and a wheel 31 is fixedly connected to the lower surface of the main support plate 1.
[0036] The device can maintain different areas of the road surface by pushing the pusher 30, and the wheel 31 enables the device to be moved.
[0037] Working principle and usage process of this utility model:
[0038] When asphalt pavement maintenance is required, the worker manually turns the right end of the crank handle 23. Due to the transmission effect of the second belt 24, the second rotating shaft 21 rotates inside the fixed frame 13, thereby driving the first helical gear 8, which meshes with the fourth helical gear 22, to rotate. Since the second fixed rod 11, which is fixedly connected to the surface of the first helical gear 8, is hinged to the first fixed rod 6 through the hinge rod 12, the sliding rack 5 moves left and right inside the slide groove 4. The surfaces of the gear 3 and the sliding rack 5 mesh with each other, thereby driving the material discharge assembly 2 to rotate inside the discharge port 28. When it rotates to a certain angle, the asphalt raw material inside the storage cylinder 26 will flow out from the lower part of the discharge port 28 and reach the ground. Since the spring 9 is in a compressed state, it pushes the extrusion plate 10 upward, so that the lower surface of the first helical gear 8 has a certain sliding friction with the extrusion plate 10. Therefore, the first helical gear 8 will not rotate when the worker does not apply force to the crank handle 23.
[0039] After the storage cylinder 26 is filled with asphalt, the motor 14 is started. The output shaft of the motor 14 rotates, which drives the second helical gear 15 to rotate. Since the third helical gear 17 meshes with the second helical gear 15, it drives the first rotating shaft 16 to rotate inside the fixed frame 13. Under the transmission action of the first belt 19, it drives the stirring rod 18 to rotate. The outer side of the stirring plate 20, which is fixedly connected to the surface of the stirring rod 18, is in contact with the inner wall of the storage cylinder 26, thereby driving the stirring of the asphalt raw material inside the storage cylinder 26 and causing the asphalt raw material adhering to the inner wall of the storage cylinder 26 to be scraped off.
[0040] The handle 23 is rotatably connected to the right surface of the fixed frame 13. Therefore, turning the right end of the handle 23 drives the transmission of the second belt 24, thereby driving the second shaft 21 to rotate. Due to the meshing of the fourth helical gear 22 with the first helical gear 8, the first helical gear 8 is given a driving force to rotate.
[0041] By opening the cylinder cover 27, asphalt raw materials enter and exit through the cylinder cover 27. The storage cylinder 26 is used to temporarily store the asphalt raw materials, which then flow out from the discharge port 28 to the road surface that needs maintenance.
[0042] The first rotating shaft 16 rotates on the upper part of the storage cylinder 26, providing support force to the first rotating shaft 16. At the same time, the discharge assembly 2 rotates inside the discharge port 28, thereby realizing the discharge and closure of the asphalt raw materials.
[0043] The support block 29 provides support to the rear end of the feeding assembly 2, so that the feeding assembly 2 can be disassembled and installed inside the discharge port 28.
[0044] The device can maintain different areas of the road surface by pushing the pusher 30, and the wheel 31 enables the device to be moved.
