Abstract
The utility model discloses a slot wall milling device for an underground continuous retention wall one-step forming machine, and relates to engineering machinery. The device is a dedicated component for 'underground continuous retention wall one-step forming' (the patent authorization publication number is CN101619573B) which is invented by the applicant. The slot wall milling device aims at solving the problem that a big arm is attracted by a side wall of a slot. The slot wall milling device is arranged on a chain. When the slot wall milling device enters into the front portion of the big arm, a cam is free of limitation and the cam and a milling cutter automatically rebound under the function of a torsional spring. The cam and the milling cutter are on the same shaft. The milling cutter extends out of the outer side of the big arm, scraps and cuts the two side slot walls of the slot. The width of the scrapped and cut slot is larger than that of the big arm. Therefore, the problem that the big arm is attracted by the dug slot is solved. When the slot wall milling device enters into the back portion of the big arm, a cam guiding plate switches the cam and the milling cutter to rotate 90 degrees. The milling cutter contracts into the big arm structure. The milling device successfully passes through the inner cavity of the big arm.
