Description

Technical Field

[0001] This invention relates to the field of highway maintenance technology, and in particular to a highway maintenance and repair device and its usage method. Background Technology

[0002] In the field of highway maintenance and repair, road surface repair and paving are crucial for ensuring road safety and extending road lifespan. Traditional highway maintenance and repair methods often rely on manual labor or simple mechanical equipment for material laying, which suffers from low efficiency, inconsistent paving quality, high labor intensity, and harsh working environments. With the continuous increase in traffic volume and the increasing demands for road maintenance, higher requirements are being placed on the automation level, paving accuracy, and operational efficiency of highway maintenance and repair equipment.

[0003] In the existing technology, although some automated or semi-automated highway maintenance equipment has been developed, these devices are often complex in structure, inconvenient to operate, and difficult to achieve efficient and uniform paving results in practical applications.

[0004] A search revealed that Chinese patent application number CN202320775125.6 discloses an asphalt paving device for asphalt construction, comprising a storage bin, a frame, and a heating and mixing blade. A paving plate is installed on one side of the bottom end of the frame, and an adjustment structure is provided on one side of the top end of the frame. The adjustment structure includes a movable block, a screw, a lifting plate, a positioning rod, and a handle. The screw is installed on one side of the top end of the frame, and a handle is installed on the top end of the screw. A movable block is installed on the outside of the screw, and a lifting plate is installed on one side of the movable block. A positioning rod is installed on one side of the inside of the lifting plate. A storage bin is installed on the top end of the frame, and a drive motor is installed on the top end of the storage bin.

[0005] A search revealed Chinese patent application number CN202221359782.4, which discloses a colored asphalt paving device, relating to the field of municipal road construction equipment technology, addressing the problem that existing asphalt paving vehicles are unsuitable for colored asphalt paving. The paving device includes a vehicle body and a cab located at the front of the vehicle, with a U-shaped frame and a roller installed at the rear. A fixed base, a storage compartment, and lifting mechanisms on the left and right sides of the fixed base are located in the middle of the vehicle body. The top of the fixed base and the bottom of the storage compartment are inclined downwards from the front to the rear of the vehicle. A discharge port is located on the lower part of the side wall of the storage compartment near the rear of the vehicle, and an insert plate is located on the inner side of the side wall of the storage compartment near the rear of the vehicle. The width of the insert plate is larger than the discharge port, and the upper end of the insert plate passes through a slot on the top of the storage compartment and connects to the lifting mechanism.

[0006] The asphalt paving device and colored asphalt paving device in the above patents have the following shortcomings: although they have paving capabilities, they cannot guarantee the uniformity of paving, and there is still room for improvement. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a highway maintenance and repair device and its usage method.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A highway maintenance and repair device includes a vehicle body, with a paving mechanism located at the front end of the vehicle body. The paving mechanism includes:

[0010] The hopper is mounted on the vehicle body via a support frame;

[0011] The material frame is fixed to the front of the vehicle body by a bracket, and the material frame is located below the output end of the hopper;

[0012] The swing arm frame is installed on the outer wall of one side of the material frame. Multiple swing arms are rotatably mounted on the swing arm frame, and a roller is installed at one end of each swing arm.

[0013] The shifter has a shift rail installed on one side, and the roller slides inside the shift rail. A guide plate is installed on one side of the material frame, and the shifter slides on the inner wall of the guide plate.

[0014] The actuator component is used to drive the reciprocating motion of the lever.

[0015] The material frame has a strip-shaped opening on the side near the swing arm frame, and the swing arms are distributed on one side of the strip-shaped opening.

[0016] During use, the laying material is output from the hopper and enters the material frame. Based on the movement of the vehicle body, the laying material is exposed through the strip opening to achieve the laying effect. During this process, the push component pushes the lever, which in turn drives each swing arm to swing, thereby achieving the purpose of assisting the laying and improving the laying effect.

[0017] Preferably, a protruding ball is fixed at one end of the lever, and the other end of the lever is connected to the guide plate via a first spring;

[0018] A side bracket is fixed to the side of the material frame, and a horizontal slide is slidably connected inside the side bracket. A corrugated plate is fixed to the outer wall of one side of the horizontal slide. A convex ball is located on the movement path of the corrugated plate and slides on the side of the corrugated plate based on the action of the first spring.

[0019] A ball joint rod is fixed on the corrugated plate, and a rotating seat is coaxially mounted on the wheels of the vehicle body. A dial is mounted on one end of the rotating seat, and the dial is compatible with the ball joint rod.

[0020] A guide frame is fixed on one side of the hopper, and a horizontal slide rod is slidably connected inside the guide frame. The horizontal slide rod and the horizontal slide frame are connected by a vertical frame. A mounting rod is slidably connected to one end of the horizontal slide rod. The mounting rod and the horizontal slide rod are connected by a second spring. A positioning component for fixing the mounting rod is provided on the vehicle body.

[0021] Preferably, the positioning component includes:

[0022] The first positioning frame is installed on the outer wall of one side of the vehicle body;

[0023] The second positioning frame is slidably connected to the first positioning frame. The mounting rod has evenly distributed positioning holes. One end of the second positioning frame is detachably inserted into the positioning hole. The second positioning frame and the first positioning frame are connected by a third spring.

[0024] Preferably, the output end of the hopper is fixed with an arc-shaped cover, the side of the arc-shaped cover has a fixing frame, a material roller is arranged inside the arc-shaped cover, the material roller is rotatably mounted on the fixing frame via a shaft, and a rotation control part for controlling the movement of the material roller is arranged on the side of the hopper.

[0025] Preferably, the rotation control unit includes:

[0026] Rotation drive motor, which is mounted on a fixed frame;

[0027] The gear transmission assembly connects the output end of the drive motor to the shaft of the material roller via the gear transmission assembly.

[0028] Preferably, an electric telescopic cylinder is installed on one side of the outer wall of the hopper, and the output end of the electric telescopic cylinder is fixed on a fixed frame.

[0029] Preferably, the outer circumferential wall of the material roller is provided with uniformly distributed ribs.

[0030] Preferably, the rear of the vehicle body is provided with a lifting control unit, a lifting frame is installed on the lifting control unit, and a pressure roller assembly is installed on the lifting frame.

[0031] Preferably, the lifting control unit includes a mounting frame, which is installed at the rear of the vehicle body. A hydraulic cylinder is mounted on the mounting frame, and the lifting frame is slidably connected to the inner wall of the mounting frame. The output end of the hydraulic cylinder is fixed to the lifting frame.

[0032] Preferably, the method of using the maintenance device includes the following steps:

[0033] S1: Move the vehicle to the location where construction is needed;

[0034] S2: Install the corresponding positioning hole of the mounting rod into the second positioning frame, so that the ball head rod is in contact with the outer wall of the dial wheel, and the second spring is in a stretched state;

[0035] S3: Pour the material to be laid into the hopper;

[0036] S4: Based on the rotation drive motor, the material is evenly fed into the material frame;

[0037] S5: The vehicle moves, and the material in the material frame leaks out from the strip opening for laying. At the same time, the dial wheel periodically moves the ball head rod, causing the corrugated plate to reciprocate, which in turn drives the swing arm to swing and help to flatten the material.

[0038] S6: The hydraulic cylinder adjusts the position of the lifting frame and uses the pressure roller assembly to assist in compacting the material.

[0039] The beneficial effects of this invention are as follows:

[0040] This invention, by setting up a vehicle body, material frame, swing arms and other structures, can output laying material through the hopper. The laying material enters the material frame. Based on the movement of the vehicle body, the laying material is exposed through the strip opening to achieve the laying effect. During this process, the pushing component pushes the lever, which in turn drives each swing arm to swing, thereby achieving the purpose of assisting the laying and improving the laying effect.

[0041] This invention, by setting up structures such as a dial wheel and a ball joint, can drive the dial wheel to rotate based on the rotation of the wheel, thereby actuating the ball joint. Under the deformation of the second spring, the horizontal carriage slides within the side support. Then, through the cooperation of the corrugated plate, the convex ball and the first spring, the reciprocating motion control of the dial is achieved without the need for an additional power source.

[0042] By setting up a positioning component, this invention allows the second positioning frame to be installed in different positioning holes as needed, thereby adjusting the tension of the second spring or the initial position of the horizontal slide bar; changing the amplitude of the dial wheel actuating the ball head rod; or, as needed, completely separating the dial wheel from the ball head rod, thus improving the flexibility of use.

[0043] This invention facilitates uniform material output and more even laying by setting up structures such as material rollers; by setting up structures such as electric telescopic cylinders, the distance between the material rollers and the arc-shaped cover can be adjusted, thereby adjusting the material output effect.

Example

[0053] A highway maintenance and repair device, such as Figure 1-6 As shown, the vehicle includes a vehicle body 1, and a material spreading mechanism is provided at the front end of the vehicle body 1. The material spreading mechanism includes:

[0054] The hopper 11 is mounted on the vehicle body 1 via a support frame 17;

[0055] The material frame 13 is fixed to the front end of the vehicle body 1 by a bracket, and the material frame 13 is located below the output end of the hopper 11.

[0056] A swing arm 39 is installed on one side of the outer wall of the material frame 13. Multiple swing arms 38 are rotatably installed on the swing arm 39 and are distributed at equal intervals. A roller 35 is installed at one end of each swing arm 38.

[0057] A lever 14 is provided, with a lever rail 36 installed on one side of the lever 14 and a roller 35 sliding inside the lever rail 36. A guide plate 33 is installed on one side of the material frame 13, and the lever 14 slides on the inner wall of the guide plate 33.

[0058] The actuator is used to drive the reciprocating motion of the lever 14.

[0059] The material frame 13 has a strip-shaped opening on the side near the swing arm frame 39, and the swing arms 38 are distributed on one side of the strip-shaped opening;

[0060] By setting up structures such as vehicle body 1, material frame 13, and swing arms 38, paving material, such as asphalt, can be output through the hopper 11. The paving material enters the material frame 13, and based on the movement of vehicle body 1, the paving material is discharged through the strip opening to achieve the paving effect. During this process, the pushing component pushes the lever 14, which in turn drives each swing arm 38 to swing, thereby achieving the purpose of assisting paving and improving the paving effect.

[0061] To facilitate the operation of lever 14; such as Figure 6 As shown, a protruding ball 37 is fixed at one end of the lever 14, and the other end of the lever 14 is connected to the guide plate 33 through a first spring 34;

[0062] A side bracket 27 is fixed to the side of the material frame 13. A horizontal slide 8 is slidably connected inside the side bracket 27. A corrugated plate 25 is fixed to one outer wall of the horizontal slide 8. A convex ball 37 is located on the movement path of the corrugated plate 25.

[0064] A guide frame 16 is fixed on one side of the hopper 11. A horizontal slide rod 9 is slidably connected inside the guide frame 16. The horizontal slide rod 9 and the horizontal slide frame 8 are connected by a vertical frame 31. A mounting rod 22 is slidably connected to one end of the horizontal slide rod 9. The mounting rod 22 and the horizontal slide rod 9 are connected by a second spring 18. A positioning component for fixing the mounting rod 22 is provided on the vehicle body 1.

[0065] By setting up structures such as the dial wheel 23 and the ball head rod 24, the rotation of the wheel 6 can drive the dial wheel 23 to rotate, thereby actuating the ball head rod 24. Under the deformation of the second spring 18, the horizontal slide 8 slides within the side support 27. Then, through the cooperation of the corrugated plate 25, the convex ball 37 and the first spring 34, the reciprocating motion control of the dial 14 can be achieved without the need for an additional power source.

[0068] The second positioning frame 20 is slidably connected to the first positioning frame 10. The mounting rod 22 has evenly distributed positioning holes 21. One end of the second positioning frame 20 is detachably inserted into the positioning hole 21. The second positioning frame 20 and the first positioning frame 10 are connected by a third spring 19.

[0069] By setting up the positioning components, the second positioning frame 20 can be installed in different positioning holes 21 as needed, thereby adjusting the tension of the second spring 18 or adjusting the initial position of the horizontal slide bar 9; changing the amplitude of the dial 23 moving the ball head rod 24, or, as needed, completely separating the dial 23 from the ball head rod 24, thus improving the flexibility of use.

[0070] To better output materials; such as Figure 4 , Figure 5 As shown, an arc-shaped cover 30 is fixed to the output end of the hopper 11. A fixing frame 26 is provided on the side of the arc-shaped cover 30. A material roller 29 is provided inside the arc-shaped cover 30. The material roller 29 is rotatably mounted on the fixing frame 26 via a shaft. A rotation control part for controlling the movement of the material roller 29 is provided on the side of the hopper 11.

[0071] By setting up structures such as the material roller 29, it is easy to output materials evenly, which facilitates more uniform laying.

[0073] Rotation drive motor 12 is mounted on the fixed frame 26;

[0074] The output end of the rotation drive motor 12 is connected to the shaft of the material roller 29 via the gear transmission assembly 28.

[0075] To facilitate adjustment of the discharge effect; such as Figure 4 As shown, an electric telescopic cylinder 15 is installed on one side of the outer wall of the hopper 11, and the output end of the electric telescopic cylinder 15 is fixed on the fixed frame 26.

[0076] By setting up structures such as the electric telescopic cylinder 15, when the electric telescopic cylinder 15 is working, it can push the fixing frame 26 of the mounting roller 29 along the direction of movement of the output end of the electric telescopic cylinder 15, combined with Figure 4 , Figure 5 This changes the relative position of the material roller 29 and the arc-shaped cover 30, thereby adjusting the distance between the material roller 29 and the arc-shaped cover 30, and thus adjusting the discharge effect.

[0077] To better output materials; such as Figure 4 , Figure 5 As shown, the outer circumferential wall of the material roller 29 is provided with uniformly distributed ribs 32.

[0078] To facilitate smoothing; such as Figure 1 As shown, a lifting control unit is provided at the rear of the vehicle body 1, a lifting frame 4 is installed on the lifting control unit, and a pressure roller assembly 5 is installed on the lifting frame 4.

[0079] To facilitate smoothing; such as Figure 1 As shown, the lifting control unit includes a mounting frame 3, which is installed at the rear of the vehicle body 1. A hydraulic cylinder 2 is installed on the mounting frame 3. The lifting frame 4 is slidably connected to the inner wall of the mounting frame 3. The output end of the hydraulic cylinder 2 is fixed on the lifting frame 4.

[0080] By setting up structures such as a lifting control unit and a pressure roller assembly 5, it is easy to control the height of the pressure roller assembly 5 based on the lifting control unit, and to flatten the laid material by the pressure roller assembly 5. Example

[0081] A method of using a highway maintenance and repair device, such as Figure 1-6 As shown, this embodiment, based on embodiment 1, includes the following steps:

[0082] S1: Move vehicle 1 to the location where construction is required;

[0083] S2: Install the corresponding positioning hole 21 of the mounting rod 22 into the second positioning frame 20, so that the ball head rod 24 is in contact with the outer wall of the dial wheel 23, and the second spring 18 is in a stretched state;

[0084] S3: Pour the material to be laid into the hopper 11;

[0085] S4: Based on the rotation drive motor 12, the material is evenly fed into the material frame 13;

[0086] S5: The vehicle body 1 moves, and the material in the material frame 13 leaks out from the strip opening for laying. At the same time, the dial wheel 23 periodically moves the ball head rod 24, causing the corrugated plate 25 to reciprocate, which in turn drives the swing arm 38 to swing and help to flatten the material.

[0087] S6: Hydraulic cylinder 2 adjusts the position of lifting frame 4, and uses pressure roller assembly 5 to assist in compacting the material.

[0088] The above description is only a preferred embodiment of the present invention. For the parts not disclosed in detail, such as the specific circuit connection method or the instrument model, those skilled in the art can implement them using conventional technical means, so they will not be described in detail.
