Description
Technical Field
[0001] This utility model belongs to the field of roadbed construction technology, specifically relating to a roadbed construction leveling device. Background Technology
[0002] The roadbed is the foundation of the road surface. It bears the weight of its own soil and rock, the weight of the road surface, and the traffic load transmitted from the road surface. It is the main load-bearing body of the highway. When laying the roadbed, leveling and compaction operations must be carried out. Appropriate leveling devices are used when leveling the roadbed.
[0003] Traditional leveling devices include structures such as a rectangular frame, rectangular box, bulldozer blade, lifting plate, rectangular sleeve, rectangular slot, spring, rectangular insert, rectangular groove, guide rod, lifting seat and drive motor. The advantage of this leveling device is that the height of the bulldozer blade can be adjusted.
[0004] However, traditional leveling devices lack a locking structure, which makes the position adjustment structure (drive motor) easily damaged by abnormal force during use. This results in poor reliability of the leveling device and affects the user experience. Improvement is urgently needed. Utility Model Content
