Problems solved by technology

[0003] In mine production, the hoisting winch in the mining area is mainly responsible for the transportation of equipment and materials in the underground mining area of ​​the mine. With the improvement of mine mechanization level, underground fully mechanized mining, fully mechanized excavation equipment and supports are widely used, and large mechanical equipment is becoming more and more It often enters the mining area, so the hydraulic brake device of the hoisting winch is a very important device. In the existing mine, in order to meet the requirements of transporting large and heavy mining equipment up and down the mountain in the mining area, in recent years, the main mining area under the mine Both the up and down hill hoisting winches use high-power dispatching winches (motor power is 55-90kw). Although the lifting capacity of the dispatching winch meets the requirements, it is found that the power of the brake oil pump of the original winch braking system is relatively small during use (the braking force is 180N ), and it is one-sided braking. The brake adopts belt-type friction brake pads, uses the brake lever to transmit torque, and brakes by the friction force generated by the brake pads and brake wheels. Since the brake oil pump is restricted Due to power constraints, when lifting or lowering heavy objects such as fully mechanized mining equipment (such as hydraulic support weighing up to 11t), the original winch electromagnetic brake cannot meet the braking requirements, and the manual brake is also difficult to meet, especially when the winch suddenly loses power or is in an emergency. In the stopped state, the braking system of the winch cannot achieve reliable braking, which may easily cause major vicious accidents such as sports cars, and bring difficulties to the transportation of large equipment in the mining area. Due to insufficient braking torque, many unsafe hidden dangers are caused

Abstract

The invention provides an outer-rotor explosion-proof permanent magnet motor type mining winch with rope arrangement. The outer-rotor explosion-proof permanent magnet motor type mining winch with rope arrangement comprises a base and a control device, wherein an outer-rotor motor and a reciprocating lead screw type rope arranger are fixedly installed on the base, and the outer-rotor motor and the reciprocating lead screw type rope arranger are in transmission connection through a chain, and the outer-rotor motor is electrically connected with the control device. When the control device controls the outer-rotor motor to rotate forwards, the reciprocating lead screw type rope arranger is driven to wind a steel wire rope on a shell of the outer-rotor motor layer by layer, and a mine car is lifted; and when the control device controls the outer-rotor motor to rotate reversely, the reciprocating lead screw type rope arranger is driven to unwind the steel wire rope wound on the shell of the outer rotor motor layer by layer, and the mine car descends. The outer-rotor explosion-proof permanent magnet motor type mining winch with rope arrangement is an electric multi-layer winding type dispatching winch dragged by a single steel wire rope, and has the advantages of being simple in structure, small in appearance size and beneficial for arrangement in a narrow and small space.
