AI Technical Summary

Technical Problem

Existing aftertreatment system installation devices are difficult to meet the needs of high frequency, convenience and comprehensive maintenance under complex working conditions, especially the inconvenience of maintenance caused by exhaust pipe and the blind spot problem of sensor maintenance.

Method used

A post-processing system installation device is designed, comprising an outer shell, a cover plate assembly, and a movable limiting assembly. The cover plate assembly is rotatably connected by a first cover plate and a second cover plate, and the double-opening design expands the maintenance space. The movable limiting assembly switches between locked and unlocked positions to ensure the stability and flexibility of the cover plate.

Benefits of technology

It enables convenient and rapid inspection and replacement operations, reduces maintenance time and labor intensity, improves maintenance efficiency, avoids safety hazards caused by limit switch failure, and ensures the reliability of the device.

Abstract

The application discloses a post-processing system mounting device and a rotary drilling rig, and relates to the technical field of engineering machinery. The post-processing system mounting device comprises an outer shell, a cover plate assembly and a movable limiting assembly. The outer shell is used for accommodating the post-processing system, and the outer shell is provided with an opening through which an exhaust pipe can pass. The cover plate assembly comprises a first cover plate and a second cover plate which are rotatably connected with the outer shell respectively. Both the cover plates have a first position and a second position. When both the cover plates are located at the first position, the two cover plates close the opening. When both the cover plates are located at the second position, the two cover plates open the opening. The movable limiting assembly is movably arranged at the closing position of the two cover plates, and is used for limiting the rotation of the two cover plates when being in a locked position and releasing the limitation on the rotation of the two cover plates when being in an unlocked position. The post-processing system mounting device solves the problem that the existing device cannot meet the requirements of high frequency, convenience and all-around maintenance of the internal sensors of the post-processing system.
