Description

Battery lift car drive motor brake device

technical field

The utility model relates to the technical field of storage battery production equipment, in particular to a braking device for a driving motor of a storage battery lifting vehicle.

Background technique

At present, in the production process of batteries, in order to save labor, most of the transportation of batteries is carried by automatic chain plates or power rollers. When the battery is transported to a designated position, the battery is manually pushed into the lift car, automatically lifted to a certain height, and the motor of the lift car is stopped by sending a signal through the photoelectric switch or travel switch, so that the lift car is positioned at a specified position. height, and then manually push the battery out of the lift car to complete a change in the height of the battery.

Wherein the structure of the battery lifting car is shown in Figure 2, including a frame 1, a lifting frame 2 is arranged on the frame 1, several photoelectric switches 3 are arranged on the lifting frame 2, and a passive sprocket 4 is arranged on the upper part of the lifting frame 2 , a motor 5 is arranged on the frame 1, a driving sprocket 6 is arranged on the rotating shaft of the motor 5, a chain 7 is arranged between the driving sprocket 6 and the driven sprocket 4, and a tray 8 is arranged on the side of the frame 1 , The side of the tray 8 is provided with a sliding wheel 9, and the sliding wheel 9 is connected with the chain 7. Its working process is as follows: when in use, place the battery on the tray 8, and the motor 5 drives the chain 7 to rotate, so that the tray 8 moves up and down with the rotation of the chain 7, thereby realizing the up and down movement of the battery. When the photoelectric switch 3 detects After the signal in place, the photoelectric switch 3 sends a signal to make the motor 5 power off and stop running, thereby making the storage battery stop moving. In this process, due to factors such as the weight of the battery and the speed change of the lifting car, it is difficult for the motor 5 to stop accurately, and overshooting is prone to occur (the amount of overshooting can reach 10-40 mm). It will be corrected by manually adjusting the position of the switch, reducing the speed of the motor 5, etc., which will not only cause a lot of waste of manpower, but also greatly reduce the working efficiency of the lift car.

Utility model content

The technical problem to be solved by the utility model is to provide a braking device for driving the motor of the battery lift car that can accurately stop the motor of the battery lift car.

In order to solve the above-mentioned problems, the technical solution adopted by the utility model is: the braking device of the battery lift car drives the motor, including an elongated shaft arranged at the rear end of the rotor of the motor and a stator sleeved outside the rotor of the motor, the elongated A conical iron and an electromagnet are sequentially arranged on the shaft, and a spring is arranged between the conical iron and the electromagnet.

The elongated shaft, stator, conical iron, electromagnet and spring are all arranged in the casing of the motor.

The beneficial effects of the utility model are: the above-mentioned braking device for driving the motor of the battery lift car has a simple structure and is easy to use. It can stop the motor of the battery lift car accurately, so that the battery lift car is not easy to overshoot (the overshoot is less than 5mm), so it is not necessary to manually adjust the switch position, reduce the motor running speed and other methods to correct it, saving money. Manpower, and improve the work efficiency of the lift car.

Detailed ways

In the following, a further detailed description will be given to the braking device for the drive motor of the battery lift car of the present invention through specific embodiments.

As shown in Figure 1, the motor braking device driven by the battery lift car includes an elongated shaft 2 arranged at the rear end of the rotor 1 of the motor and a stator 3 sleeved outside the rotor 1 of the motor, and the elongated shaft 2 is sequentially A conical iron 4 and an electromagnet 5 are provided, a spring 6 is arranged between the conical iron 4 and the electromagnet 5, and the elongated shaft 2, the stator 3, the conical iron 4, the electromagnet 5 and the spring 6 are all arranged In the housing 7 of the motor.

The working principle of the utility model is: when the motor is energized and needs to run, the electromagnet 5 is energized to generate magnetism to absorb the conical iron 4. At this time, the spring 6 is in a compressed state, and the stator 3 rotates synchronously with the rotor 1 of the motor; When the electricity needs to be stopped, the electromagnet 5 is powered off and loses its magnetism. At this time, the conical iron 4 moves to combine with the stator 3 and the rotor 1 under the elastic force of the spring 6, thereby locking the stator 3 and stopping the rotor 1 of the motor. Thereby no overshoot phenomenon will occur, thus it is not necessary to manually adjust the position of the switch, reduce the running speed of the motor and other methods to correct it, which saves manpower and improves the working efficiency of the lift car.

Above-mentioned embodiment only illustrates the principle of the present invention and its effect, and the embodiment of partial use, and is not intended to limit the present utility model; Under the premise of creating the concept of the utility model, some deformations and improvements can also be made, and these all belong to the protection scope of the utility model.
