Embodiment Construction

[0021] The electromagnetic pusher of the block brake includes a static magnet 1, a moving magnet 2, an electromagnetic coil 3 and a push rod 4. The static magnet 1 has a cone, and the center of the cone has a tapered groove; the moving magnet 2 has a tapered groove for the cone of the static magnet to be inserted, and the middle part of the bottom of the tapered groove has a movable A cone within a tapered slot of a magnet. The static magnet 1 and the moving magnet 2 can be inserted into the joint, and the center of the static magnet is provided with a support shaft sleeve 5, and one end of the support shaft sleeve 5 is fixedly connected with the static magnet 1. A shaft hole that matches the sleeve 5, and the support shaft sleeve 5 can be inserted into the shaft hole. The push rod 4 is pierced in the support sleeve 5, the center of the moving magnet 2 has a screw hole, one end of the push rod 4 is screwed into the screw hole at the center of the moving magnet 2, and the othe...

Abstract

The electromagnetic thruster includes a static magnet, a movable magnet, a coil, and a push rod. The static magnet possesses a cone part, where there is a cone-shaped trough in the center. The movable magnet possesses a cone-shaped trough for the cone part of the static magnet to be placed in. there is a cone-shaped body possible to be placed to the cone-shaped trough of the movable magnet in middle part at bottom of the cone-shaped trough. The static magnet and the movable magnet can be inserted and jointed. The disclosed thruster simplifies structure of brake, and reduces volume and weight of brake. Comparing with electro hydraulic thruster integrated with electric hydraulic pressure i.e. centrifugal pump, the thruster possesses features: (1) no need of sealing oil way; (2) no problem of low temperature in oil way; (3) reduced part of second lever ratio, size and weight; (4) the smaller of travel, and the larger of thrust; (5) more energy saving and longer service life.

Description

(1) Technical field [0001] The invention relates to an electromagnetic pusher for a block brake—formerly known as an electromagnet. (2) Background technology [0002] Block brakes are widely used in lifting and transporting machinery and equipment. The existing electromagnets used for block brakes are mainly DC short-stroke electromagnets, and their application range is relatively narrow. (3) Contents of the invention [0003] The object of the present invention is to provide a medium-stroke electromagnetic pusher for a block brake with small volume, light weight, low noise, no impact, high efficiency, energy saving and long service life. [0004] The technical solutions adopted are: [0005] The electromagnetic pusher of the block brake includes a static magnet, a moving magnet, an electromagnetic coil and a push rod. The static magnet has a cone, and the center of the cone has a tapered groove; the moving magnet has a cone for the static magnet The tapered groove that ...
