Abstract
The invention relates to a storage battery lift truck driving motor braking apparatus. The apparatus comprises an extending shaft which is arranged on a rear end of a rotor of the motor and a stator which is sleeved on outside of the rotor of the motor. Tapered iron and an electromagnet are successively arranged on the extending shaft. A spring is arranged between the tapered iron and the electromagnet. The storage battery lift truck driving motor braking apparatus of the invention can be applied in the driving motor of the storage battery lift truck. By using the apparatus, the driving motor of the storage battery lift truck can stop accurately.
Description
Technical field
The present invention relates to the production equipment technical field of storage battery, refer to a kind of storage battery lift truck drive motors brake apparatus especially.
Background technology
In the production process of storage battery, for saving the labour, the conveying of storage battery mostly adopts automatic carrier bar or power drum to carry at present.After storage battery is transported to a certain assigned address, by manually storage battery being pushed lift truck, automatic lifting is to a certain height, sending signal by optoelectronic switch or travel switch stops the motor of lift truck, thereby make lift truck be positioned at a certain specified altitude assignment, manually storage battery is released lift truck again, finish the variation of a storage battery height.
Wherein the structure of storage battery lift truck as shown in Figure 2, comprise frame 1, frame 1 is provided with crane 2, and crane 2 is provided with several optoelectronic switches 3, and the top of crane 2 is provided with by movable sprocket 4, frame 1 is provided with motor 5, the rotating shaft of motor 5 is provided with drive sprocket 6, drive sprocket 6 and be provided with chain 7 between the movable sprocket 4, and the sidepiece of frame 1 is movably set with pallet 8, the sidepiece of pallet 8 is provided with movable pulley 9, and movable pulley 9 is connected with chain 7.Its course of work is: during use, storage battery is placed on the pallet 8, motor 5 chain drive-belts 7 rotate, thereby make pallet 8 along with the rotation of chain 7 moves up and down, thereby realize moving up and down of storage battery, wherein after optoelectronic switch 3 detected the signal that puts in place, optoelectronic switch 3 sends signal shut down motor 5 outages, thereby it is mobile that storage battery is stopped.This process is owing to be subjected to factor affecting such as storage battery weight and lift truck velocity variations, and motor 5 is difficult to accurately stop, and overshoot phenomenon (overshoot can reach 10～40 millimeters) takes place easily.Lean on methods such as artificial often by-pass cock position, reduction motor 5 running speeds to correct, not only cause a large amount of wastes of manpower, and greatly reduce the operating efficiency of lift truck.
Summary of the invention
Technical problem to be solved by this invention is: the storage battery lift truck drive motors brake apparatus that provides a kind of motor that can make the storage battery lift truck accurately to stop.
For addressing the above problem, the technical solution used in the present invention is: storage battery lift truck drive motors brake apparatus, the axis of elongation and the stator that is set in the rotor exterior of motor that comprise the rotor rear end that is arranged on motor, be disposed with taper iron and electromagnet on the described axis of elongation, be provided with spring between taper iron and the electromagnet.
The described axis of elongation, stator, taper iron, electromagnet and spring all are arranged in the shell of motor.
The invention has the beneficial effects as follows: above-mentioned storage battery lift truck drive motors brake device structure is simple, easy to use.It can make the motor of storage battery lift truck accurately stop, make the storage battery lift truck be not easy to take place overshoot phenomenon (overshoot is less than 5 millimeters), thereby need not lean on artificial often by-pass cock position, reduce methods such as motor rotation speed and correct, save manpower and improved the operating efficiency of lift truck.

Embodiment
Below by specific embodiment storage battery lift truck drive motors brake apparatus of the present invention is described in further detail.
As shown in Figure 1, storage battery lift truck drive motors brake apparatus, the axis of elongation 2 and the stator 3 that is set in rotor 1 outside of motor that comprise rotor 1 rear end that is arranged on motor, be disposed with taper iron 4 and electromagnet 5 on the described axis of elongation 2, be provided with spring 6 between taper iron 4 and the electromagnet 5, the described axis of elongation 2, stator 3, taper iron 4, electromagnet 5 and spring 6 all are arranged in the shell 7 of motor.
Operation principle of the present invention is: when electrical power need turn round, electromagnet 5 got electric generation magnetic with 4 absorption of taper iron, and this moment, spring 6 was in compressive state, and the rotor 1 that taper iron 4 is followed motor rotates synchronously; When the motor outage need stop, electromagnet 5 outages lose magnetism, taper this moment iron 4 moves under the elastic force of spring 6 with stator 3 and rotor 1 and combines, thereby with stator 3 lockings, the rotor 1 of motor is shut down, thereby overshoot phenomenon can not take place, thereby need not lean on artificial often by-pass cock position, reduce methods such as motor rotation speed and correct, save manpower and improved the operating efficiency of lift truck.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
Claims (1)
1. storage battery lift truck drive motors brake apparatus, the axis of elongation and the stator that is set in the rotor exterior of motor that comprise the rotor rear end that is arranged on motor, it is characterized in that: be disposed with taper iron and electromagnet on the described axis of elongation, be provided with spring between taper iron and the electromagnet, the described axis of elongation, stator, taper iron, electromagnet and spring all are arranged in the shell of motor, when electrical power need turn round, electromagnet gets electric generation magnetic taper iron is adsorbed, this moment, spring was in compressive state, and the rotor that taper iron is followed motor rotates synchronously; When the motor outage need stop, the electromagnet outage lost magnetism, and taper this moment iron moves under the elastic force of spring with stator and rotor and combines, thereby with the stator locking, the rotor of motor was shut down.
