Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, and in particular to a vehicle-mounted asphalt crack sealing device. Background Technology

[0002] Road surface crack repair is a crucial aspect of road maintenance, and asphalt crack sealing technology has become the mainstream crack treatment method due to its advantages such as convenient operation, moderate cost, and stable repair results. Vehicle-mounted asphalt crack sealing devices are core equipment for road maintenance.

[0003] The existing simplified crack sealing devices have an inadequately optimized steering structure design. This prevents operators from easily checking and calibrating the sealing accuracy and condition from the back of the device. Consequently, operators cannot directly adjust the device's trajectory from behind to ensure the sealing direction aligns with the cracks on the road for precise and effective repair. Instead, an additional person is required to operate the steering structure from the front of the device to adjust its trajectory in real time. This necessitates at least two people to operate the device, which is not only cumbersome and inconvenient but also wastes manpower. Utility Model Content

[0004] In view of this, the present invention provides a vehicle-mounted asphalt crack sealing device to solve the problem that crack sealing devices require at least two people to operate together, which is troublesome, inconvenient and wastes manpower.

[0005] The technical solution proposed by this utility model is as follows: a vehicle-mounted asphalt crack sealing device, specifically including a frame chassis, a longitudinal slide rod slidably arranged at the top of the frame chassis, and a herringbone fork welded to one end of the frame chassis; a bogie is rotatably mounted at the first end of the horizontal part of the herringbone fork, the bogie is composed of two symmetrically arranged vertical support pipes, a steering wheel and a steering column welded together, a transmission rod is welded on one of the vertical support pipes, and a connecting rod is rotatably connected between the transmission rod and the first end of the longitudinal slide rod; a front wheel is rotatably mounted between the bottom ends of the two vertical support pipes; a strip-shaped drive frame is integrally formed on the longitudinal slide rod and arranged crisscrossingly therewith; three U-shaped support frames are welded at intervals at the top of the frame chassis, a T-shaped drive column is rotatably mounted through one of the U-shaped support frames, a swing drive rod is welded to the bottom part of the T-shaped drive column, a short shift shaft is integrally formed at the bottom of the first end of the swing drive rod, and the short shift shaft is slidably engaged with the strip-shaped drive groove inside the strip-shaped drive frame.

[0006] Furthermore, two transverse bushings are symmetrically welded through the rear ends of the two long side plates of the frame chassis. A wheel axle is rotatably installed through the two transverse bushings, and a rear wheel is fixedly fitted at both ends of the wheel axle.

[0007] Furthermore, three short connecting frames and one long connecting frame are welded around the two transverse bushings, and an assembly space is formed between the two transverse bushings. A driven gear is fixedly mounted on the axle in the assembly space. A drive assembly is fixedly installed inside the long connecting frame, and the driving gear and the driven gear mesh and transmit power on the power output shaft of the drive assembly.

[0008] Furthermore, a row of longitudinally placed foot axles is welded between the horizontal bracing beams of the two closely spaced U-shaped support frames, and a horizontal bearing ring is welded between the two widely spaced U-shaped support frames, with a disc-shaped electric heater fixed through the horizontal bearing ring.

[0009] Furthermore, an asphalt tank is fixedly mounted on the top of the disc-shaped electric heater, a stirring roller is rotatably installed inside the asphalt tank, and a drive unit is fixedly mounted on the top opening of the asphalt tank. The power output shaft of the drive unit is connected to the central rotating shaft of the stirring roller. A Z-shaped discharge pipe is welded to the center of the bottom of the asphalt tank. The vertical part of the top of the Z-shaped discharge pipe passes through a disc-shaped electric heater, and a solenoid valve is installed on the vertical part.

[0010] Furthermore, a rectangular vertical support frame is welded to the bottom of one of the U-shaped support frames, and an electrical control box is fixedly installed on the top part of the rectangular vertical support frame. The electrical control box is equipped with an electrical control unit for controlling the start and stop of the drive unit, the disc-shaped electric heater, and the start, stop, and steering of the drive assembly.

[0011] Furthermore, a battery box is fixedly installed on the top of the frame chassis, and a lithium battery is built into the battery box. The lithium battery is used to power the drive unit, the disc-shaped electric heater and the drive assembly.

[0012] The vehicle-mounted asphalt crack sealing device provided by this utility model has the following beneficial effects: 1. During the crack filling and repair operation, the construction operator stands on a row of longitudinal foot pedals to operate the crack filling device. Standing on the longitudinal foot pedals behind the crack filling device, the construction operator can easily observe the position of the Z-shaped discharge pipe and its flow of asphalt in real time through the gap between the longitudinal foot pedals. This allows the operator to grasp the actual situation of the asphalt crack filling trajectory and adjust the crack filling trajectory in a timely manner so that the crack filling trajectory can adapt to follow the direction of the crack and carry out precise crack filling and repair.

[0013] Second, the crank-slider mechanism is the steering structure of the crack sealing device. The T-shaped drive column, as the component that directly operates the steering structure, is located behind the crack sealing device and close to the construction operator standing on the longitudinal foot axle. This allows the construction operator to easily check and calibrate the crack sealing accuracy and actual condition from behind the crack sealing device. The operator can then directly operate the steering structure through the T-shaped drive column to adjust the travel trajectory of the crack sealing device, aligning the crack sealing direction with the cracks on the road for precise and effective crack sealing repair. This invention eliminates the need for an additional person to manually operate the bogie at the front of the crack sealing device to adjust its travel trajectory, and also eliminates the need for at least two people to operate the crack sealing device. It is not only more convenient to operate, but also saves labor and reduces the operating cost of the crack sealing device. Attached Figure Description

Three short connecting frames 1042 and one long connecting frame 1041 are welded around the two transverse bushings 104. An assembly space is formed between the two transverse bushings 104. A driven gear 1071 is fixedly fitted on the part of the wheel axle 107 located in the assembly space. A drive assembly 10 is fixedly installed inside the long connecting frame 1041. The driving gear mounted on the power output shaft of the drive assembly 10 meshes with the driven gear 1071 for transmission.

[0021] Preferably, a row of longitudinally placed foot axles 1011 is welded between the cross bracing beams of two closely spaced U-shaped support frames 101, and a horizontal bearing ring 106 is welded between two widely spaced U-shaped support frames 101, with a disc-shaped electric heater 12 fixed through the horizontal bearing ring 106.

[0025] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: Through the power transmission of the driving gear and driven gear 1071, the drive assembly 10 can rotate in both directions to drive the axle 107 and the two rear wheels 4 to roll in either direction, thereby driving the crack sealing device forward or backward. The asphalt tank 2 contains high-temperature molten liquid asphalt, and the disc-shaped electric heater 12 is used to heat and keep the asphalt in the asphalt tank 2 at a high-temperature liquid and flowable state. The longitudinal slide bar 102, connecting rod 1021, bogie 9, and transmission rod 904 are connected to form a modified crank-slider mechanism. Through this mechanism, the reciprocating sliding of the longitudinal slide bar 102 can drive the bogie 9 to rotate in both directions to control the steering of the front wheels 3, thereby adjusting the travel path and crack sealing trajectory of the crack sealing device. 2. The sliding engagement and power transmission with the internal strip drive groove of the strip drive frame 1022, using the T-shaped drive column 8 to rotate the drive rod 801 in both directions, can drive the strip drive frame 1022 and the longitudinal slide bar 102 to slide back and forth along the length of the frame chassis 1, controlling the front wheel 3 to steer; after opening the solenoid valve 202, liquid asphalt flows down through the bottom outlet of the Z-shaped discharge pipe 201 into the cracks on the road surface to repair the cracks. The drive assembly 10 can drive the crack filling device to travel along the road surface. By adjusting the steering of the front wheel 3, the travel path of the crack filling device and the crack filling trajectory of the Z-shaped discharge pipe 201 can be changed, so that the crack filling trajectory is aligned with the direction of the crack, and the crack filling repair is carried out more accurately and effectively.

[0026] During crack filling and repair work, the construction operator stands on a row of longitudinally placed foot axles 1011 to operate the crack filling device. Standing on the longitudinally placed foot axles 1011 behind the crack filling device, the construction operator can easily observe the position of the Z-shaped discharge pipe 201 and its asphalt flow in real time through the gaps between the longitudinally placed foot axles 1011, and grasp the real-time situation of the asphalt filling trajectory so as to adjust the filling trajectory in time, so that the filling trajectory can adapt to follow the direction of the crack and carry out precise crack filling and repair. The aforementioned crank-slider mechanism is the steering structure of the crack filling device, and the T-shaped drive column 8, as the component that directly operates the steering structure, is set behind the crack filling device and close to the construction operator standing on the longitudinally placed foot axles 1011. This design allows construction operators to stand behind the crack sealing device for easy inspection and calibration of the sealing accuracy and actual condition. They can then directly adjust the device's trajectory via the T-shaped drive column 8, aligning the sealing direction with the cracks on the road for precise and effective repair. This eliminates the need for an additional person to manually operate the bogie 9 at the front of the device to adjust its trajectory, and also avoids the need for at least two people to operate the device. This not only makes operation more convenient but also saves labor and reduces the operating costs of the crack sealing device.

[0027] It is worth noting that the solenoid valve 202 is electrically connected to the electronic control unit and controls the switch through the electronic control unit. The composition of the electronic control unit, its connection and wiring method with the solenoid valve 202, lithium battery, drive unit 6, disc electric heater 12 and drive assembly 10, and its control principle for these components are existing technologies for those skilled in the art engaged in equipment electrification design, and therefore will not be described in detail here.
