Title:
GRINDING MECHANISM FOR FORMWORK OF TUNNEL LINING TROLLEY, AND TUNNEL CONSTRUCTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/000974
Kind Code:
A1
Abstract:
Disclosed is a grinding mechanism for a formwork of a tunnel lining trolley, the mechanism comprising a mounting frame (100), a driving member (200), a rotary disc (210), a link rod (300), a rocker arm (400) and a cleaning assembly. The driving member is used for driving the rotary disc to rotate, such that the link rod can be driven by the rotary disc to reciprocate; the rocker arm can be driven by the link rod to rotate relative to the mounting frame so as to drive the cleaning assembly to grind a formwork (600) on a tunnel lining trolley. Compared with driving by a hydraulic oil cylinder, the mode of the rotary disc, the link rod and the rocker arm cooperating to drive the cleaning assembly to grind the formwork allows the grinding mechanism for a formwork of a tunnel lining trolley to achieve a higher transmission speed when supplying power to the cleaning assembly, thereby effectively improving the grinding effect of the cleaning assembly. Also disclosed is a tunnel construction apparatus.
