Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and more specifically, to a road surface maintenance device for highway engineering road construction. Background Technology

[0002] Road construction and maintenance are crucial for ensuring road safety and smooth traffic flow. During use, roads suffer damage and wear due to factors such as vehicles and weather, requiring timely repair and maintenance. For example, Chinese Patent 202310337307.X discloses a high-performance asphalt mixture pavement maintenance device and process. This application uses a frame with rollers mounted at its bottom for movement. An outer tank, in conjunction with an inner tank, holds the materials for maintenance and repair. The device is further enhanced by a main heating tank, a drive motor, and a mixing shaft. The material is melted and then pumped out by a material pump and discharged from the discharge pipe and hopper for road surface filling and maintenance. The pressure roller flattens the repaired area. When the filler needs to be replaced, the top cover can be removed via the mating ring and assembly ring, and the inner tank can be taken out. The inner tank, along with the new filler and its container, is then connected to the outer tank. When the inner tank is placed into the outer tank, the pressure rod presses against the top plug, creating a gap between the top plug and the outer frame, allowing the filler material to flow down from the outer frame to the material pump, facilitating material replacement. In this road maintenance device, the asphalt is stored in a barrel on the frame. Asphalt retrieval is cumbersome, requiring a material pump. Due to the special properties of asphalt, the pipeline is prone to clogging. Furthermore, the fixed size of the discharge opening makes it difficult to control the discharge volume, and a suitable opening adjustment mechanism is lacking. Utility Model Content

[0047] The control box 3 is mounted on the vehicle frame and is connected to the drive motor 7 and the discharge mechanism. It is used to control the operation of the drive motor 7 and the discharge mechanism.

[0048] In some embodiments of this utility model, the fixing seat includes two fixing plates 4 arranged opposite to each other along the left and right direction of the frame. The two fixing plates 4 together define a channel for the barrel 5 to rotate freely around the pivot axis, and at least one of the fixing plates 4 is provided with a limiting guide groove 9 to guide the barrel 5 during the rotation process.

[0049] In some embodiments of this utility model, the limiting guide groove 9 is an upwardly convex arc shape.

[0051] In some embodiments of this utility model, the discharge mechanism includes a discharge seat 10 disposed at the discharge port of the barrel 5. The discharge seat 10 is provided with a discharge channel and a through structure that connects the discharge channel. The discharge channel is connected to the inner cavity of the barrel 5. A discharge adjustment mechanism for regulating the discharge of the discharge seat 10 is disposed at the through structure.

[0052] In some embodiments of this utility model, the discharge adjustment mechanism includes a baffle 14, a bracket 15 mounted on the discharge seat 10, and an electric push rod 16 mounted on the bracket 15. The baffle 14 is movably inserted into the through structure. The electric push rod 16 is connected to the baffle 14 and electrically connected to the control box 3, and is used to adjust the position of the baffle 14 in the through structure to block part or all of the discharge channel. Specifically, the control box 3 controls the electric push rod 16, which extends and retracts, causing the baffle 14 to slide relative to the discharge seat 10, thereby adjusting the opening of the discharge end and achieving discharge adjustment.

[0053] Please see Figure 1 , Figure 4 and Figure 5 The bottom end of the frame 1 is provided with a leveling motor 17, which is electrically connected to the control box 3. The bottom end of the leveling motor is connected to a support column 18, and the outer end of the support column 18 is detachably provided with a leveling seat 19.

[0054] In some embodiments of this utility model, the leveling seat 19 is symmetrically provided with mounting rods 20 inside. The support column 18 has mounting holes 21 corresponding to the two mounting rods 20. Each of the two mounting rods 20 has a mounting ring 22 at its outer end, and the mounting rods 20 and mounting rings 22 are threadedly connected. Specifically, the control box 3 controls the leveling motor 17, which drives the support column 18 to rotate. The support column 18 then drives the leveling seat 19 to rotate, thus leveling the road surface. After prolonged use, rotating the mounting ring 22 engages with the mounting rod 20 threadedly. After removing the mounting ring 22, the leveling seat 19 is replaced, and the mounting rods 20 are installed corresponding to the mounting holes 21.

Move to a suitable position and start the curing operation.

[0061] When in the discharge adjustment state, the control box 3 starts the drive motor 7, which drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the barrel 5 to rotate relative to the fixed plate 4 for adjustment. The guide rod 8 and the limit guide groove 9 cooperate to guide the rotation. When the barrel 5 is rotated to a horizontal position, the asphalt is discharged relative to the discharge seat 10 and poured into the position to be cured. After the barrel 5 is rotated to a horizontal position, the control box 3 adjusts the extension and retraction of the electric push rod 16. The electric push rod 16 drives the baffle 14 to slide and adjust the opening of the discharge seat 10, which facilitates the control and adjustment of the discharge amount. When adding material, the drive motor 7 rotates in the opposite direction, and the barrel 5 is tilted to a suitable position. Material is added into the barrel 5 through the fully opened discharge seat 10.

[0062] When in the leveling state, the control box 3 controls the leveling motor 17, which drives the support column 18 to rotate. The support column 18 drives the leveling seat 19 to rotate, thus leveling the road surface. After long-term use, rotate the mounting ring 22. The mounting ring 22 and the mounting rod 20 are threaded together. After removing the mounting ring 22, the leveling seat 19 can be replaced. The mounting rod 20 is installed in the mounting hole 21. The mounting ring 22 and the mounting rod 20 are threaded together to lock the installation, which facilitates replacement and extends the overall service life of the device.
