Detailed Description
As shown in fig. 1-3, the cage stall protection device includes a frame 1, two guide ropes 2 are respectively freely hung on two sides of the frame 1, two guide wheels 3 arranged in a housing 401 in front and back and clamping the guide ropes 2 on the corresponding side are installed on one side of the frame 1, a centrifugal releaser 4 is installed on a rotating shaft of one of the guide wheels 3, and the centrifugal releaser 4 is composed of a housing 401, two sliding shafts 402 arranged in radial symmetry and penetrating through the housing 401, a slide block 403 fixedly installed at the inner end of the sliding shaft 402, and a spring 404 sleeved on the sliding shaft 402 and connected between the slide block 403 on the corresponding side and the inner wall of the housing 401. A catcher which is used for clamping two guide ropes 2 and is started by a centrifugal releaser 4 is arranged on the frame 1. The catcher is composed of an oil pump 5 which is hinged on a frame 1, an oil cylinder 6 which is hinged on the frame 1 and is connected with the oil pump 5 through a pipeline, an oil valve 7 which is arranged on the pipeline and is close to a centrifugal releaser 4, shifting forks 8 which are hinged on two sides of the frame 1 and are connected with the piston rod of the oil cylinder 6 at the tail end, tapered slideways 9 which are arranged on two sides of the frame 1 and are narrow at the top and wide at the bottom, and two wedge-shaped clamping plates 10 which are arranged in the tapered slideways 9, are respectively arranged on the front side and the back side of a guide rope 2 and.
