AI Technical Summary

Technical Problem

When filling large cracks, the existing highway asphalt pavement maintenance device needs to repeatedly adjust the device position, which is time-consuming and labor-intensive, reduces flexibility, and is inconvenient to clean up the remaining asphalt in the shell, resulting in waste of resources.

Method used

A high-speed asphalt pavement maintenance structure including a mobile vehicle, a housing, a discharge pipe, a driving fine-tuning mechanism and a stirring and scraping mechanism is designed. Through the coordination of the servo motor and the threaded rod, the fine adjustment of the discharge pipe is achieved, which facilitates the adjustment of the position of the asphalt discharge; at the same time, through the coordination of the mixing motor and the scraper, it is convenient to clean the remaining asphalt in the shell.

Benefits of technology

It reduces labor force, improves flexibility and convenience during use, facilitates maintenance and maintenance, and avoids waste of resources.

Abstract

The utility model discloses a high-speed asphalt pavement maintenance structure which comprises a moving trolley, a shell and a driving fine adjustment mechanism, the shell is installed at the top of the moving trolley, a discharging pipe communicated with the shell is installed at the bottom of the shell, and the bottom end of the discharging pipe penetrates through the moving trolley and extends to the outside of the moving trolley. The driving fine adjustment mechanism is arranged on the moving vehicle and comprises a fixing shell. Through mutual cooperation of the fixed shell, the servo motor, the threaded rod, the threaded block, the movable plate, a rotating motor, a drainage plate, a baffle, an inserting block, an inserting groove, a stabilizing block and a fastening bolt, the discharging direction of the discharging pipe after asphalt is discharged can be changed, and the situation that the whole device needs to be repeatedly pushed to move when the discharging direction is adjusted is avoided; therefore, the labor force is reduced, the flexibility and convenience in use are improved, the driving fine adjustment mechanism can be conveniently detached for maintenance and overhaul in the later period, and the practicability is improved.
