AI Technical Summary
In asphalt pavement construction, the roughening position is low and the surface width is small, making it difficult to use electric roughening equipment. Manual roughening is inconvenient and inefficient, and cleaning is time-consuming and labor-intensive.
An asphalt pavement joint treatment device was designed, which includes a chiseling and cleaning mechanism, comprising a chiseling rod, front and rear cleaning rollers and linkage components. Driven by a displacement motor and a chiseling motor, it realizes automated chiseling and cleaning. The reciprocating movement and height adjustment of the device are realized by using a threaded rod and a bevel gear structure.
It improved the efficiency and quality of chiseling, reduced the labor intensity of construction workers, and automated the chiseling and cleaning operations.
