Technical Field

[0001] The utility model relates to the technical field of municipal highway engineering, in particular to a municipal highway repair device. Background Technique

[0002] Highway engineering refers to the work of surveying, measuring, designing, constructing, maintaining, and managing highway structures. Highway engineering structures include: subgrade, pavement, bridge, culvert, tunnel, drainage system, safety protection facilities, greening, and traffic monitoring facilities, as well as houses, workshops, and other service facilities used for construction, maintenance, and monitoring.

[0003] In municipal highway engineering, repair is included. For example, a portable highway repair device with the Chinese patent publication number CN211285194U has a fixed seat arranged on the vehicle body. The fixed seat is internally provided with a combustion chamber, and a surrounding plate and a fixing frame are arranged at the upper end of the fixed seat. When in use, the heating barrel is first fixed on the fixing frame, and one end of the heating barrel extends into the combustion chamber.

The presence of the combustion chamber and the surrounding plate can effectively improve the utilization rate of heat, and the effect is better; the fixing frame is fixed on the first fixing rod and the second fixing rod. When it is necessary to pour out the materials in the heating barrel, first lift the fixing frame upward, then fold the second fixing rod to one side, and then the fixing frame can be rotated to pour the materials, which is more convenient. By setting an air compressor, a high-pressure air nozzle can be externally connected to clean cracks or potholes, effectively improving work efficiency and quality.

The front middle part of the top end of the vehicle board 1 is connected to the bottom end of the connecting frame 3. The upper and lower sides inside the connecting frame 3 are respectively rotationally connected to the upper and lower ends of the threaded rod 5 through a group of bearings 4. The collar 6 is movably sleeved on the outer side of the threaded rod 5, and a group of fixing nuts 7 are respectively screwed on the upper and lower ends of the collar 6 on the outer side of the threaded rod 5. The front end of the collar 6 is connected to the middle part of the rear side of the fixed semi-ring 9 through the second connecting frame 8. The front side of the bottom end of the fixed semi-ring 9 is connected to the threaded groove frame 10. The front side of the top end of the fixed semi-ring 9 is movably connected to the rear side of the top end of the movable semi-ring 11 through the hinge 24. The rear side of the bottom end of the movable semi-ring 11 is connected to the top end of the fixing piece 12. A fixing bolt 13 is movably arranged inside the fixing piece 12. A moving mechanism is arranged at the bottom of the vehicle board 1. First, move the collar 6 vertically to the corresponding height on the outer side of the threaded rod 5, and then fix it by screwing the two fixing nuts 7 on the outer side of the collar 6. Then, open the movable semi-ring 11, and the vehicle body hanging ring can be sleeved inside the fixed semi-ring 9. Then, close the movable semi-ring 11 under the restraint of the hinge 24, so that the fixing piece 12 and the threaded groove frame 10 are corresponding. Then, the fixing bolt 13 can be screwed into the threaded groove frame 10 to connect the fixing piece 12 and the threaded groove frame 10, and act on the closing and fixing of the movable semi-ring 11 and the fixed semi-ring 9. At this time, the device can be connected to the tractor. During the movement of the tractor, it can be moved by the moving mechanism through the connecting tractor board 1, and through the rotational restraint of the two bearings 4 on the threaded rod 5, it can adapt to the steering movement.

[0026] The moving mechanism includes a spring 14, a damper 15, an axle movable frame 16, an axle 17 and a roller 18. The front and rear sides of the bottom end of the vehicle board 1 are respectively connected to the top ends of multiple springs 14. The bottom ends of the springs 14 are connected to the top end of the axle movable frame 16. A damper 15 is also connected inside the spring 14 between the vehicle board 1 and the axle movable frame 16. The inner side of the axle movable frame 16 is rotationally connected to the outer side of the axle 17. The left and right ends of the axle 17 are respectively connected to the middle parts of the inner ends of a group of rollers 18. With the bottom ends of the four rollers 18 contacting the ground, the axle 17 can roll on the ground under the restraint of the axle movable frame 16, and through the energy consumption of the damper 15, the spring 14 acts on the vehicle board 1 for shock absorption to improve stability.

[0027] It also includes a push handle frame 19 and a push handle rod 20. The rear side of the top end of the vehicle board 1 is connected to the bottom end of the push handle frame 19. The upper side of the inner end of the push handle frame 19 is connected to the left and right ends of the push handle rod 20. By holding the push handle rod 20, under the connection of the push handle frame 19, it can act on the vehicle board 1 for pushing to improve convenience.

[0028] It further includes an anti-wear pad 21. The inner sides of the fixed semi-ring 9 and the movable semi-ring 11 are respectively connected to the outer sides of a group of anti-wear pads 21. Through the anti-wear pads 21, the fixed semi-ring 9 and the movable semi-ring 11 can contact the towing vehicle hanging ring, reducing wear and improving reliability.

[0031] In summary, when a municipal road repair device is in use, first move the collar 6 vertically on the outer side of the threaded rod 5 to the corresponding height, then screw and fix two sets of fixing nuts 7 on the outer side of the collar 6. After that, open the movable semi-ring 11, and the vehicle body hanging ring can be sleeved inside the fixed semi-ring 9. Through the anti-wear pads 21, the fixed semi-ring 9 and the movable semi-ring 11 can contact the towing vehicle hanging ring. Then close the movable semi-ring 11 under the constraint of the hinge 24, making the fixing piece 12 and the screw groove frame 10 correspond. Then the fixing bolt 13 can be screwed into the screw groove frame 10 to connect the fixing piece 12 and the screw groove frame 10, and act on the closure and fixation of the movable semi-ring 11 and the fixed semi-ring 9. At this time, the device can be connected to the towing vehicle. During the driving process of the towing vehicle, through the towing vehicle connecting plate 1, the bottom ends of the four sets of rollers 18 contact the ground. The axle 17 can roll on the ground under the constraint of the axle movable frame 16, and the energy is dissipated through the damper 15. The spring 14 acts on the vehicle plate 1 for shock absorption. And through the rotation constraint of the two sets of bearings 4 on the threaded rod 5, it can adapt to the steering movement. In addition, through the grip push rod 20, under the connection of the push rod frame 19, it acts on the vehicle plate 1 for pushing. In addition, through the oil injection nozzle 22, the inner wall of the bearing 4 can be oiled, which is convenient for lubrication and maintenance. After installing the oil injection cap 23 on the outer side of the oil injection nozzle 22, the inside of the oil injection nozzle 22 can be hermetically protected, improving reliability.
