Description

Technical Field

[0001] The utility model relates to the technical field of road paving devices, in particular to a road paving device for municipal road construction. Background Art

[0002] In municipal road construction, a road paving device is a heavy machine specially used to lay and level ground materials (such as concrete, asphalt or mortar) to the required thickness and width. The device is usually composed of a scraper, an operating lever, a propulsion system, an automatic level control system and a power source. The power source is usually a diesel engine, which provides the required power for the entire machine. It can drive the propulsion system and provide energy for other auxiliary facilities such as vibrators and heaters. The vibrator is used to further compact the paving material, while the heater can maintain the appropriate temperature of the material in cold weather to facilitate construction. The use of a road paving device can significantly improve construction efficiency and road quality and reduce labor intensity. In order to achieve the best working results, operators need to undergo professional training and understand the operating principles and maintenance methods of the equipment.

[0003] According to the search, the Chinese patent document, announcement number: CN214423072U, has been found. The technical field of the road paving device involved in this application is proposed. Aiming at the defect that the paving operation of sand and gravel in municipal road construction is difficult, a road paving device for municipal road construction is proposed, including a scraper, rollers are arranged at both ends of the scraper, the rotation axis direction of the roller is parallel to the length direction of the scraper, the bottom end of the scraper protrudes to the outer peripheral surface of the roller, and the side of the scraper is also hinged with a tie rod, the rotation axis of the tie rod is parallel to the rotation axis of the roller, and the scraper is also provided with a fastening assembly for fixing the tie rod. This application has the effect of making the paving of sand and gravel in municipal road construction simpler and more convenient.

[0004] When using the road paving device for municipal road construction, there is a lack of a mechanism for locking the scraper height, and the operator must manually adjust the scraper through an operating lever to assist in paving the mortar on the ground. However, manual adjustment makes it difficult to ensure that the scraper always maintains a constant height during operation, which may lead to inconsistent road paving effects and thickness fluctuations, thereby reducing the overall construction quality. In view of this, we provide a road paving device for municipal road construction. Utility Model Content

[0024] When in use, the paver 1 is aligned with the slide rail 102 through the slider 101, and after the paver 1 is slidably connected to the outer wall of the slide rail 102 through the slider 101, the control motor 201 is driven to rotate the driving tooth 1 202, so that the driving tooth 204 drives one of the transmission rods 203 on the top to rotate. After the transmission rod 203 rotates, the transmission tooth 205 on the outer wall of the transmission rod 203 and the conical tooth 207 at the bottom engage with each other, so that the two transmission rods 203 inside the paver 1 can rotate synchronously in opposite directions at the same time, driving the lifting motor 301 on the top surface of the paver 1. As the scraper 3 passes through the top surface The guide rails 304 and the limit blocks 305 on both sides are restricted at the bottom of the paver 1 and can only slide vertically up and down along the inner wall of the limit block 305.

After the scraper 3 is adjusted to the combined position, the control motor 201 is driven to achieve the paving and leveling of the ground cement mortar, effectively ensure the consistency of the height of the ground cement mortar, and further improve the construction quality.

[0029] Working principle: When in use, align the paver 1 with the slide rail 102 through the slider 101, and after the paver 1 is slidably connected to the outer wall of the slide rail 102 through the slider 101, the control motor 201 is driven to rotate the driving tooth 1 202, so that the driving tooth 204 drives one of the top transmission rods 203 to rotate. After the transmission rod 203 rotates, the transmission tooth 205 on the outer wall of the transmission rod 203 and the conical tooth 207 at the bottom engage with each other, so that the two transmission rods 203 inside the paver 1 can rotate synchronously in opposite directions at the same time, driving the lifting of the top surface of the paver 1. Lowering motor 301, since the scraper 3 is restricted at the bottom of the paver 1 by the guide rails 304 and the limit blocks 305 on both sides of the top surface, it can only slide vertically up and down along the inner wall of the limit block 305. When the threaded sleeve 302 rotates, the threaded shaft 303 drives the scraper 3 fixed on the bottom surface to rise and fall vertically along the inner wall of the limit block 305 to the specified position through the inner wall thread, so that the device cooperates with the lifting motor 301 through the control motor 201. After the scraper 3 is adjusted to the appropriate position, the control motor 201 is driven to achieve the paving and leveling of the cement mortar on the ground.
