[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an easy-to-maintain road leveling device, including a leveling vehicle, a leveling device for leveling the road surface is arranged under the leveling vehicle, two installation slots far away from each other are arranged on the outer surfaces of both sides of the leveling vehicle, and the inner wall surfaces of the installation slots are provided with threaded grooves for positioning, and two fixed base frames far away from each other are arranged under the leveling vehicle, and the fixed base frame is a U-shaped structure as a whole, and a card-mounting cavity is arranged inside the upward-curved two ends of the fixed base frame, and adjustment grooves connected to the outside of the fixed base frame are arranged on the inner side wall surfaces of the card-mounting cavity, and support frames with an eight-shaped structure are inserted and installed in the two card-mounting cavities, and walking-assisting wheels are movably installed in the two ends of the support frames, and locking slots are arranged on the side walls corresponding to each other of the two support frames, and the locking slots are provided with a second locking socket for positioning, and the locking socket two is provided with a thread.

[0005] Furthermore, a synchronization beam is inserted and installed between the two locking slots, and docking slots corresponding to the size of the second locking socket are provided inside both ends of the synchronization beam. The two ends of the synchronization beam are inserted into the locking slots and locked by bolts.

[0006] Furthermore, the size of the upturned ends on both sides of the fixed base corresponds to the internal space of the installation slot, and locking holes are provided inside the upper ends of both sides of the fixed base. The upper ends of the fixed base are inserted into the corresponding two installation slots and locked by bolts.

[0007] Furthermore, two telescopic motors are fixedly mounted on the surface of the leveling vehicle and are located far away from each other. The output shafts of the telescopic motors penetrate the interior of the leveling vehicle and extend to the bottom of the leveling vehicle.

[0008] Furthermore, a synchronous socket with a smooth inner wall is provided on the surface of the synchronous crossbeam, and the output end of the telescopic motor passes through the synchronous socket and is locked and installed by a collar.

[0009] Beneficial Effects

[0010] The utility model provides a road leveling device that is easy to maintain and has the following beneficial effects:

[0011] 1. This road leveling device, which is easy to maintain, is provided with a support frame that can adjust the height autonomously. After the two support frames are respectively inserted into the card-mounting cavities opened inside the two sides of the fixed base frame, the positions of the support frames are adjusted so that the sides of the two support frames with locking slots are corresponding to each other, and at the same time, the synchronous crossbeam is passed through the adjustment slot into the interior of the card-mounting cavity and inserted into the locking slot on the surface of the support frame. After the bolt passes through the locking socket second and is rotated and locked inside the docking slot, the two support frames are movably installed inside the fixed base frame through the synchronous crossbeam, and the fixed base frame is fixed. The top of the frame is inserted into the installation slot to complete the installation. Two fixed base frames support the entire leveling vehicle. After the telescopic motor is installed on the surface of the leveling vehicle, the output shaft of the leveling vehicle passes through the through hole reserved on the surface of the leveling vehicle and extends to the bottom of the leveling vehicle and is inserted into the synchronous jack opened on the surface of the synchronous beam. The installation is completed after locking the output shaft of the telescopic motor with a ring. When the telescopic motor is started, the output shaft of the telescopic motor will drive the synchronous beam to move up and down, and the synchronous beam will drive the two support frames to move inside the card cavity, thereby realizing the overall lifting and lowering of the leveling vehicle.

[0012] 2. This road leveling device, which is easy to maintain, is provided with a leveling device for leveling the ground. After the leveling device is installed under the leveling vehicle, the motor inside the leveling device will drive the rollers under the leveling device to rotate. When the rollers under the leveling device come into contact with the ground, the rollers rotate to press and level the concrete laid on the road surface. When the entire device is used up, the two telescopic motors are started, and the output shafts of the two telescopic motors push the two synchronous beams downward, driving the walking wheels installed on both sides of the four support frames to come into contact with the ground, thereby lifting the entire device as a whole. After the rollers at the bottom of the leveling device leave the ground, the entire device can be quickly pushed to change position, thereby greatly improving the mobility of the device.

When the entire device is used up, the two telescopic motors 5 are started, and the output shafts of the two telescopic motors 5 push the two synchronous beams 10 downward, driving the walking wheels 12 installed on both sides of the four support frames 6 to contact the ground, and lifting the entire device as a whole. After the roller at the bottom of the leveling device 2 leaves the ground, the entire device can be quickly pushed to change position, which greatly improves the mobility of the device.
