Composite belt drift signalling and pull-rope stopping device

The utility model relates to a composite belt drift signalling and pull-rope stopping device. The upper end of a guard roller shaft (15) is provided with a guard roller (16), and the lower end is connected with two cam connecting shafts which are provided with torsion springs (13) by a right angle support frame (17). The respectively corresponding positions of cams (9) (14) are provided with limit switches (10). The inner end of a rotary arm shaft (24) which is provided with one torsion spring (22) is connected with one cam (20), and the corresponding position is provided with one limit switch (21). The outer end is provided with a rotary arm (23), and the rotary arm is connected with a steel cable. A positioning shaft (5) which is provided with one torsion spring (4) is fixed with a positioning sleeve (2), the front end is a semi-circle shape, and the outer end is provided with a handle. The device has the functions of two devices: a belt drift signalling switch and a pull-rope stopping switch. The utility model is convenient to the centralized management and maintenance, the use is convenient, and the laying of cable lines can be decreased.
