Problems solved by technology
[0002] At present, the mining dispatching winch produced and used in China adopts two-stage planetary gear transmission or two-stage internal gear plus one-stage planetary gear transmission. The transmission parts have eight gears and two or one planetary carrier, and are lubricated with grease. , so there are many transmission links with complex structures, high cost, high noise, low efficiency, poor lubrication conditions, the operator's hand-held clutch and brake are easily entangled by the wire rope, causing injury accidents, and no power saving.
[0003] Through searching, it is found that there is a double-speed multi-purpose winch application number 89218687.9, and a variable-speed bearing dispatching winch application number 96212958.5 without a continuously variable speed dispatching winch with frequency converter speed regulation

Embodiment Construction
[0009] When the switch K is closed, the four-quadrant heavy-duty explosion-proof inverter (a known product) is powered on and is in the standby state. When lifting or pulling objects, press the start button. FC coil circuit, ZC2 is connected to the control circuit for self-protection, ZC3 is connected to the STF terminal to the SD terminal, and the three-phase AC explosion-proof squirrel-cage asynchronous variable frequency motor (a known product) is turned on for forward rotation, and the acceleration is started by setting the parameters of the frequency converter The function of time and torque boost makes the winch start from 0 frequency to the set frequency every time it starts, which is called soft start. It is equivalent to the smooth closing of the mechanical clutch. When the towing object reaches the designated place, press the stop button to stop the motor. Because the S helical gear worm gear reducer (a known product) has a reverse self-locking function, the heavy obj...

The invention relates to hoisting and hauling equipment, in particular to a stepless speed change winch, which is used for solving the problems that the conventional winch cannot change speed, has low working efficiency, easily hurts people and has large labor intensity for operators when a roller winds steel wire ropes, and cannot control in far or close distance flexibly during operation. The winch has the advantages of compact structure, safety, high efficiency and energy conservation. The winch comprises a chassis (1), a bracket (2), the roller (4), a speed reducer (5), a motor (6) and a transducer (7), wherein the bracket is arranged on the left side of the chassis; and the speed reducer is arranged on the right side of the chassis. The winch is mainly used for hoisting objects in construction industry, material hauling and prop drawing caving in mining industry.
Description
technical field [0001] The invention relates to a coal mine material hauling equipment, in particular to a continuously variable speed dispatching winch. Background technique [0002] At present, the mining dispatching winch produced and used in China adopts two-stage planetary gear transmission or two-stage internal gear plus one-stage planetary gear transmission. The transmission parts have eight gears and two or one planetary carrier, and are lubricated with grease. Therefore, there are many transmission links with complex structures, high cost, high noise, low efficiency, poor lubrication conditions, and the operator's hand-held clutch and brake are easily entangled by steel wire ropes, causing injury accidents, and do not save electricity. [0003] It is found by searching that there are two-speed multi-purpose winch application number 89218687.9, and the variable speed bearing dispatching winch application number 96212958.5 does not have a continuously variable speed d...
