Problems solved by technology

[0002] The electromagnetic device that uses the law of electromagnetic induction to realize the conversion and transmission of electric energy is called a motor. The motor plays a vital role as the heart of mechanical movement equipment. When using equipment for work, some dangerous situations may occur. Here Sometimes the motor needs to be powered off, but due to the inertia, the shaft cannot be stopped in an emergency, which will further cause harm to equipment and personnel.

Embodiment 1

[0042] Regarding the method of emergency stop of the motor when the motor is working, the specific steps are as follows:

[0043] S1. At first, the rotation of the main engine 1 drives the rotating shaft 2 to rotate at a speed of 2000r / min. Under the action of the huge centrifugal force, the ball 7 continues to move outward, because the movement of the ball 7 drives the slider 6 to move, and the slider 6 The movement of is bound by the fixed rod 5;

[0044] S2. The sliding rod 6 gradually squeezes the return spring 8 during the movement, and the arc plate 9 moves outward under the extrusion of the ball 7. The guide rod 10 moves stably;

[0045] S3. Immediately after the movement of the guide rod 10 cooperates with the connecting rod 11 to pull the pull rod 14, the movement of the pull rod 14 drives the splint 15 to move, and the splint 15 gradually compresses the negative pressure rod 20 when moving, and at the same time cooperates with the movable shaft 16 to drive the chain...

Embodiment 2

[0050] Regarding the method of emergency stop of the motor when the motor is working, the specific steps are as follows:

[0051] S1. At first, the rotation of the main engine 1 drives the rotating shaft 2 to rotate at a speed of 2500r / min. Under the action of the huge centrifugal force, the ball 7 continues to move outward, because the movement of the ball 7 drives the slider 6 to move, and the slider 6 The movement of is bound by the fixed rod 5;

[0052] S2. The sliding rod 6 gradually squeezes the return spring 8 during the movement, and the arc plate 9 moves outward under the extrusion of the ball 7. The guide rod 10 moves stably;

[0053] S3. Immediately after the movement of the guide rod 10 cooperates with the connecting rod 11 to pull the pull rod 14, the movement of the pull rod 14 drives the splint 15 to move, and the splint 15 gradually compresses the negative pressure rod 20 when moving, and at the same time cooperates with the movable shaft 16 to drive the chain...

Embodiment 3

[0058] Regarding the method of emergency stop of the motor when the motor is working, the specific steps are as follows:

[0059] S1. At first, the rotation of the main engine 1 drives the rotating shaft 2 to rotate at a speed of 3000r / min. Under the action of the huge centrifugal force, the ball 7 continues to move outward, because the movement of the ball 7 drives the slider 6 to move, and the slider 6 The movement of is bound by the fixed rod 5;

[0060] S2. The sliding rod 6 gradually squeezes the return spring 8 during the movement, and the arc plate 9 moves outward under the extrusion of the ball 7. The guide rod 10 moves stably;

[0061] S3. Immediately after the movement of the guide rod 10 cooperates with the connecting rod 11 to pull the pull rod 14, the movement of the pull rod 14 drives the splint 15 to move, and the splint 15 gradually compresses the negative pressure rod 20 when moving, and at the same time cooperates with the movable shaft 16 to drive the chain...

Abstract

The invention relates to the technical field of motors, and discloses a device for emergency stop of a motor during motor working. The device comprises a host and a heteropole magnetic plate; a rotating shaft is fixedly mounted on an output shaft of the host; a seat stand is movably connected to the outer wall of the rotating shaft; a lapping plate is fixedly mounted on the outer wall of the seat stand; and a fixing rod is fixedly mounted on the front surface of the rotating shaft. According to the device and method for emergency stop of the motor during the operation of the motor, a round ball moves outwards to extrude a reset spring and an arc plate, the arc plate is pressed to move and then drives a guide rod to move under the limitation of a clamping groove and a limiting rod, movement of clamping plates is matched with a movable shaft to drive a magnetic block to move; and when emergency stop is needed, the reset spring needs to recover elastic deformation, the arc plate moves under the action of a negative pressure rod and a connecting rod, meanwhile, the negative pressure rod drives the clamping plates to move, and finally, the rotating shaft is extruded to stop under the cooperation of the two clamping plates, so that the rotating shaft is restrained and clamped along with stopping of the motor, and the rotating shaft is controlled to stop in time.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a device and method for emergency stop of a motor during motor operation. Background technique [0002] The electromagnetic device that uses the law of electromagnetic induction to realize the conversion and transmission of electric energy is called a motor. The motor plays a vital role as the heart of mechanical movement equipment. When using equipment for work, some dangerous situations may occur. Here Sometimes the motor needs to be powered off, but due to the inertia, the rotating shaft cannot be stopped in an emergency, which will further cause harm to equipment and personnel. [0003] Therefore, there is a need for a device and method for emergency stopping of the motor during motor operation, which has the function of stopping the rotating shaft in a timely and controlled manner as the motor stops during the emergency stop and power-off process. [0004] The motor stops ro...
