Problems solved by technology
Since there is no lifting device specially designed for mining rescue, traditional winches are mostly used as the lifting device at present. The load of the lifting device fluctuates greatly, and the use of ordinary winches is prone to sudden changes in speed, resulting in rope breakage accidents, resulting in equipment damage and secondary injuries to personnel

The invention discloses a safely lifting device with large rope capacity. The safely lifting device with the large rope capacity comprises a rack, a rotary drum, a rotating shaft, a planet gear hydraulic brake, an end cover, a first bearing, a sleeve, a second bearing, a winch motor, a normally opened brake caliper and a normally closed safety caliper. The rotary drum is hinged to the rack through the rotating shaft. The sleeve is fixedly connected with the rack through bolts. The first bearing is hinged to the rack. The planet gear hydraulic brake is hinged to the sleeve. The second bearing is hinged to the sleeve. The normally opened brake caliper and a normally closed safety caliper are fixedly mounted on the two sides of the rack. The winch motor is fixedly connected with the rotary drum through the planet gear hydraulic brake. The invention further discloses a control method for the safely lifting device with the large rope capacity. According to the safely lifting device with the large rope capacity and the control method for the safely lifting device, under the conditions of power failure and overspeed, dual guarantee of braking through the planet gear hydraulic brake and braking through the normally opened brake caliper and the normally closed safety caliper is achieved, and it is guaranteed that the safely lifting device with the large rope capacity ascends and descends safely and reliably.
Description
technical field [0001] The invention belongs to the technical field of mine rescue equipment, and in particular relates to a safety hoisting device with a large rope capacity and a control method thereof. Background technique [0002] When underground accidents cause miners to be trapped, the mining safety hoist can be used as a hoisting system. In order to ensure the safety of personnel during the rescue and lifting process, the lifting device requires a high safety factor. Since there is no lifting device specially designed for mining rescue, traditional winches are mostly used as the lifting device at present. The disadvantage is that it is impossible to accurately control the lifting and lowering speed of rescue equipment. The load of the lifting device fluctuates greatly, and the use of ordinary winches is prone to sudden changes in speed, resulting in rope breakage accidents, resulting in equipment damage and secondary injuries to personnel.
