Embodiment

[0021] Refer Figure 1-3 One motor line protection device includes the outer casing 1, and the outer walls of the outer casing 1 are inserted with two pieces of patch block 2, and the inner wall of the outer casing 1 fixes the separator 3, the side wall sealing of the separator 3 is slidable. The connecting rod 4, two ends of the link 4 respectively secure the finite spool 5, and the inner wall of the outer casing 1 fixes the electromagnet 7, and the inside of the limiter box 5 is provided with a control speed mechanism. The end is equipped with a connecting mechanism.

[0022] The control speed mechanism includes two transfer grooves 9 extending through the sidewall of the speed limit box 5, and the two-symmetrical inner walls of the speed limit box 5 are connected by the storage spring 10, and the two baffles 11 are commonly fixed with telescopic rods 13. The sidewalls of the two baffles 11 are formed through the microfillet 12, and the outer casing 1 is filled with hydraulic oil...

Abstract

The present invention disclose a motor line protection device which comprises a shell, two power connection blocks are inserted in the two side walls of the shell in a penetrating manner, a partition plate is fixed to the inner wall of the shell, a connecting rod is slidably connected to the side wall of the partition plate in a sealing and penetrating manner, and a speed limiting box and a power connection rod are fixed to the two ends of the connecting rod respectively. An electromagnet is fixed to the inner wall of the shell, a speed control mechanism is arranged in the speed limiting box, and power connection mechanisms are arranged at the two ends of the power connection rod. The device has the advantages that by arranging the transfer groove, when large-amplitude overload occurs, the larger the overload amplitude is, the larger the extension degree of the telescopic rod is, the larger the displacement amount of the baffle is, hydraulic oil can pass through the transfer groove in a larger amplitude, the larger the overload amplitude is, the stronger the magnetism is, the stronger the adsorption capacity to the speed limiting box is, and on the whole, the larger the overload amplitude is, the higher the moving speed of the speed limiting box is, the higher the power-off speed is, and the electrical safety of the motor is effectively protected.

Description

Technical field [0001] The present invention relates to the field of motor technology, and more particularly to a motor line protection device. Background technique [0002] The motor refers to an electromagnetic device that implements electrical energy conversion or transmission based on electromagnetic induction. Its main role is to generate drive torque, as a power source of electricity or various mechanical, widely used in various industries; [0003] As the driving component, the motor often requires a sustained operation to ensure processing efficiency, and the operation of the motor requires electricity support to some extent, in particular, when the line is overloaded, it is often damaged the motor life, and the motor itself has A certain strength can resist a certain degree of overload change, but it is not possible to operate, causing more power protection of the electric power protection, and the existing motor does not have a line protection mechanism, causing the mot...
