Abstract
The utility model discloses a variable automatic tension type winch with self-locking function, which comprises a tension vehicle, pulley blocks, a steel wire, a buffer, a tension indicator, a motor and a tension winch. The steel wire is twisted on the capstan of the tension winch; and the other end of the steel wire is connected with the tension vehicle. The tension vehicle and the tension winch are two parts which are correspondingly arranged; the motor is arranged on the tension winch as a power source for pulling. The outer end of the steel wire twisted on the capstan of the tension winch is twisted on one pulley block on the tension vehicle, moves around a pulley on the buffer, is transferred to another pulley block on the tension vehicle from the buffer, and then is connected with the tension indicator. The steel wire is twisted on the capstan of the tension winch; the buffer and the tension indicator are connected with the steel wire; and a variable controller can control the motor. The utility model has a simple integral structure, is convenient to be operated and used, is suitable for a tension device matched on a belt type conveyor, and has the characteristics of adjustable speed, reversed self-locking, impact easing, and reliable motion.
Description
Technical field:
The utility model relates to the winch gear of colliery with belt conveyer, relates in particular to the frequency conversion with auto-lock function and strains the formula winch automatically.
Background technology:
At present the colliery mostly is hydraulic pressure with the automatic tension winch of belt conveyer and strains winch automatically, and the brake mode of the automatic tension formula winch of prior art adopts mechanical braking or electromagnetic braking substantially.These two kinds of brake mode all make integral structure comparatively complicated, and fiduciary level is relatively poor.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of frequency conversion simple in structure, that service-strong has auto-lock function to strain the formula winch automatically.
The formula winch is strained in frequency conversion with auto-lock function described in the utility model automatically, includes tension car, assembly pulley, steel rope, energy disperser, tension indicator, motor, worm reducer and tensioning winch and forms.Motor is connected with tensioning winch with worm reducer by coupler, is fixed on the frame, and steel rope is wrapped on the capstan winch of tensioning winch, and the other end of steel rope is connected with the tension car.Tension car and tensioning winch are corresponding two parts that are provided with, and are furnished with the propulsion source of motor as pulling on the tensioning winch.Steel rope on the tensioning winch, the assembly pulley of tension on the car walked around in the outer end, and the pulley on the bypass buffer device again is by turn back again another group assembly pulley on the tension car of energy disperser, walk around second group of assembly pulley on the tension car then, connect tension indicator again.
During work, when the needs tension, motor drives worm reducer by coupler and rotates, and drives the tensioning winch forward rotation, thereby makes the steel rope tension, realizes the tension function.After tension finished, motor stopped operating, because worm reducer has reverse auto-lock function, made that winch can not backward rotation, thereby kept pull of steel wire.When the needs slack rope, the motor counter-rotating drives the worm reducer backward rotation by coupler, and makes the winch counter-rotating, thereby steel rope is loosened.The effect of energy disperser is to slow down the impact of adhesive tape to worm reducer, and the effect of sensor is to detect pull of steel wire, and the effect of frequency-variable controller is the control rotating speed of motor.
The formula winch is strained in frequency conversion with auto-lock function described in the utility model automatically, integral structure is simple, easy for operation, be applicable to the take-up device of colliery with adapted on the belt conveyer, have adjustable-speed, oppositely self-locking, slow down the characteristics of impact, reliable in action.
Description of drawings:
Accompanying drawing is the structural representation that the formula winch is strained in the frequency conversion with auto-lock function described in the utility model automatically.Accompanying drawing 1 is that the structural representation that the formula winch is overlooked state is strained in the frequency conversion with auto-lock function described in the utility model automatically; Accompanying drawing 2 is structural representations of side-looking state.1-tension car, 2-assembly pulley, 3-steel rope, 4 one energy dispersers, 5-tension indicator, 6 one motors, 7-worm reducer, 8-tensioning winch
The specific embodiment:
Referring now to accompanying drawing 1 and accompanying drawing 2, in conjunction with the embodiments the formula winch being strained in the frequency conversion with auto-lock function described in the utility model automatically is described in detail as follows: the formula winch is strained in the frequency conversion with auto-lock function described in the utility model automatically, includes tension car 1, assembly pulley 2, steel rope 3, energy disperser 4, tension indicator 5, motor 6 and worm reducer 7 and tensioning winch 8 compositions.Motor 6 is connected with tensioning winch 8 with worm reducer 7 by coupler, is fixed on the frame, and steel rope 3 is wrapped on the capstan winch of tensioning winch 8, and the other end of steel rope 3 is connected with tension car 1.Tension car 1 and tensioning winch 8 are corresponding two parts that are provided with, and tensioning winch 8 is with the propulsion source of motor 6 as driving.Steel rope 3 on the capstan winch of tensioning winch 8, the assembly pulley 2 of tension on the car 1 walked around in the outer end, and the pulley on the bypass buffer device 4 again is by turn back again another group assembly pulley 2 on the tension car 1 of energy disperser 4, walk around second group of assembly pulley 2 on the tension car 1 then, connect tension indicator 5 again.Motor 6 and worm reducer 7 and winch 7 are fixedly mounted on the frame, coupler is connected motor 6 with worm reducer 7, coupler is connected worm reducer 7 with tensioning winch 8, steel rope 3 is wrapped on the capstan winch of tensioning winch 8, energy disperser 4 and tension indicator 5 are connected on the steel rope, frequency-variable controller may command motor 6.During work, when needs tensions, frequency-variable controller control motor 6 rotates, and drives worm reducer 7 by coupler and rotate, and by coupler and drive tensioning winch 8 forward rotation, thereby makes steel rope 3 tensions, realizes the tension function.After tension finished, motor 6 stopped operating, because worm reducer 7 has reverse auto-lock function, made that tensioning winch 8 can not backward rotation, thereby kept the pulling force of steel rope 3.When the needs slack rope, 6 counter-rotatings of frequency-variable controller control motor drive worm reducer 7 backward rotation by coupler, and make tensioning winch 8 counter-rotatings, and steel rope 3 is loosened.The effect of energy disperser 4 is to slow down the impact of adhesive tape to worm reducer 7, and tension indicator 5 also can be called sensor, and its effect is to detect pull of steel wire, and the effect of frequency-variable controller is the rotating speed of control motor 6.The formula winch is strained in frequency conversion with auto-lock function described in the utility model automatically, integral structure is simple, easy for operation, be applicable to the take-up device of colliery with adapted on the belt conveyer, have adjustable-speed, oppositely self-locking, slow down the characteristics of impact, reliable in action.
