Description

Technical Field

[0001] The utility model relates to the technical field of highway engineering construction equipment, in particular to a road surface compacting device for highway engineering construction. Background Art

[0002] The task of building or reconstructing a highway is determined according to the highway network planning. During the ground construction process, the ground needs to be compacted by a compactor. The working parts of the compactor are the hammer head and the hammer rod. A pair of working groove wheels, driven by the transmission system, can clamp the hammer rod and lift the hammer head to a certain height. Then, the hammer rod is released to allow the hammer head to fall freely to complete the compaction operation. A good compaction device can speed up the ground compaction efficiency and bring good economic benefits to the construction party.

[0003] The utility model relates to the technical field of highway engineering construction equipment, specifically a compacting machine (CN208762840U), which solves the problem that the compacting machine needs to compact the road surface through vibration of a vibration plate during operation, so vibration will occur. When the operator operates the compacting machine, the arm will vibrate along with the handrail, and long-term operation will cause the operator's hand numbness. The key points of its technical solution are: both ends of the handrail are provided with a protective cover, and the protective cover is provided with a shock-absorbing cover for shock absorption, and the shock-absorbing cover is also provided with a buffer sheet; a plurality of clamping rings are integrally provided on the inner side wall of the protective cover, and a clamping groove for clamping the clamping ring is provided on the handrail; a plurality of dovetail blocks are integrally provided at one end of the buffer sheet, and a dovetail groove for clamping the dovetail block is provided at the other end of the buffer sheet. The compacting machine of the utility model buffers the vibration force transmitted to the arm when the compacting machine is working, and the operator is not prone to hand numbness after long-term operation, thereby improving the use efficiency of the compacting machine. However, during use, a large amount of dust is generated when compacting the road surface, and the dust diffuses into the entire working environment. Since the compacting device is a mechanical equipment, the dispersed dust may enter the body of the machine, causing a large amount of dust to be distributed in the inner wall cavity of the machine, resulting in transmission obstruction, and then reducing the service life of the equipment, causing trouble to the user.

[0004] For this reason, we propose a road surface compacting device for highway engineering construction. Utility Model Content

[0011] Furthermore, the lower end of the lower flange is connected to a tamping seat for tamping the highway pavement via a flange, and a dustproof sleeve wraps the connecting frame and the lower flange for dustproof protection.

[0012] Furthermore, the end of the dustproof sleeve away from the fixed clamping plate is fastened with bolts to the top of the tamping seat, and the dustproof sleeve is a corrugated retractable structure.
