Embodiment 1

[0011] Example 1: When the switch K is closed, the frequency converter is powered on and is in the standby state. When lifting or pulling an object, press the start button ZQA, the forward rotation relay ZC is closed, and the normally closed contact FC is at the same time 1 Disconnect the FC coil circuit of the reverse relay, ZC 2 Turn on the control loop to protect itself, ZC 3 Connect the motor from the STF end to the SD end to rotate forward, and through the set inverter parameters "start acceleration time and torque boost" function, the winch starts from 0 frequency to the set frequency every time it starts forward, which is called soft start, which is equivalent to Due to the smooth closing of the mechanical clutch, when the towing object reaches the designated place, press the stop button to stop the motor, and because the S helical gear worm gear reducer (a well-known product) has a reverse self-locking function, the heavy object can be kept in place Keep. When the re...

Embodiment 2

[0012] Embodiment 2: Frequency conversion motor is used 6 pole motors, frequency 50Hz rotating speed 1000 revs / min, frequency converter maximum frequency is set as 200Hz rotating speed 4000 revs / mins, at this moment the motor heat dissipation is good and need not add cooling fan, and cylinder is straight through 225 millimeters, The first pair of reduction gears of the S helical worm gear reducer is 10:1, the worm gear reduction wheel is 10:1, the frequency conversion motor is 50Hz, the speed is 1000 rpm, and the average rope speed is 6 m / min. It can be used as a column winch. . When the frequency is 200Hz, the motor speed is 4000 rpm, and the average rope speed is 24 m / min. It can be used as a dispatching winch. To achieve a dual-use machine. This embodiment only provides one of the frequency setting values, the straight diameter of the drum, and the transmission ratio data of the S helical gear worm gear reducer. According to this embodiment, those skilled in the art can th...

Abstract

The invention relates to hoisting traction and hauling equipment, in particular to a winch with stepless speed change. The equipment is used for solving the problems that the prior winch can not change the speed and has low working efficiency, people are easy to hurt and the labor intensity of an operator is large when a roller is wound by steel cables, and the prior winch can not be flexibly controlled in far and near distances. The equipment has the advantages of compact structure, safety, high efficiency and energy conservation. The equipment comprises a chassis (1), a bracket (2) arrangedon the left side of the chassis, the roller (4), a speed reducer (5) arranged on the right side of the chassis, an electromotor (6) and a transducer (7). The equipment is mainly used for hoisting objects in the building industry, hauling materials and drawing props in the mine exploitation industry.

Description

Technical field: [0001] The invention relates to a lifting, pulling and hauling equipment, in particular to a winch capable of stepless speed change. Background technique [0002] At present, the winches used in construction lifting, mining and other industries have the problems of not being able to smoothly and continuously variable speed, low work efficiency, labor-intensive operations for operators holding the handle, easy to hurt people during the wire rope winding process, and incapable of long-distance maneuvering. Contents of the invention [0003] The object of the present invention is to provide a safe, high-efficiency and energy-saving continuously variable speed winch with frequency converter speed regulation. [0004] The present invention is realized by adopting the following technical solutions: [0005] 1. The left side bracket (2) is installed on the chassis (1) and the shaft of the drum (4) is connected to the bearing of the bracket shoe (3). The other en...
