Automatic grinding and coating device for tunnel secondary lining trolley panel

Abstract

The present utility model discloses an automatic grinding and coating device for tunnel secondary lining trolley panel (70). The first and second walking frames (1, 2) are symmetrically arranged on both sides of the secondary lining trolley body (7). The coating mechanism (4) consists of two walking seats (31) and a coating assembly mounted on two walking seats (31). The two walking seats (31) are mounted on the first walking frame (1) and the second walking frame (2), respectively. Each walking seat (31) is equipped with a drive unit that enables the walking seat (31) to reciprocate along the first walking frame (1) or the second walking frame (2). The coating assembly consists of a beam (40) mounted in the axial direction of the secondary lining trolley plate (70), and a spraying module (41) is mounted on the beam (40). According to the automatic grinding and coating device for the secondary lining trolley plate (70) of the present utility model, the walking seats (31) can be moved along the first (1) and second walking frames (2), the spraying module (41) sprays the release agent onto the secondary lining trolley plate (70), and the spraying process is automatically completed by the device, which is characterised by high work efficiency, reduces manual labour intensity, and saves time and labour costs.
