Abstract
The utility model discloses a monorail crane electromagnetic braking device, and belongs to supporting facilities of a monorail crane. The monorail crane electromagnetic braking device is mainly composed of a brake frame, a brake force arm, a brake shoe, a reset spring and electromagnets. The brake shoe is hinged to one end of the brake force arm. The electromagnets annularly surround the front end of the brake shoe. The other end of the brake force arm is hinged to a hinged block. The reset spring is connected with the hinged block in a fastened mode. The brake force arm is tightly pulled by the reset spring during normal running; the brake shoe does not make contact with a rail; when braking needs to be conducted, the electromagnets are powered on, the currents in the powered-on electromagnets on the two sides of the rail are opposite in direction, the ends, close to the rail, of the two electromagnets have opposite polarities, and attraction force is produced; when the attraction force exceeds the pull force of the reset spring, the brake shoe is tightly pressed on the rail so that braking can be achieved. After the electromagnets are powered off, the braking device resets under the action of the reset spring. By means of the monorail crane electromagnetic braking device, a traditional braking oil cylinder is omitted, and use is more convenient and more rapid.
Description
Technical field
The utility model patent relates to a kind of brake equipment, relates in particular to a kind of monorail crane electro-magnetic braking device.
Background technology
At present, the brake equipment of monorail crane mostly is hydraulic brake system, and monorail crane must add a set of hydraulic efficiency pressure system to guarantee effective use of hydraulic brake system, and such brake equipment cost is comparatively expensive, and the volume of equipment is larger.Therefore, prior art awaits further improving and development.
Summary of the invention
The utility model provides a kind of monorail crane electro-magnetic braking device in order to solve defect of the prior art, replaces the hydraulic brake system using now.
For addressing the above problem, the utility model scheme comprises:
A kind of monorail crane electro-magnetic braking device, it is mainly made up of brake bracket, the braking arm of force, braking brake shoe, retracing spring and electromagnet.Braking brake shoe is hinged on one end of the braking arm of force, and electromagnet annular is enclosed in braking brake shoe front end, and the other end and the hinged block of the braking arm of force are hinged, and retracing spring and hinged block are fastenedly connected.The retracing spring tension braking arm of force in the time of normal operation, braking brake shoe does not contact with track, in the time that needs are braked, electromagnet energising, the electromagnet electrical current of track both sides is contrary, two electromagnet are different near one end magnetic pole of track, produce adsorption affinity, in the time that adsorption affinity exceedes retracing spring pulling force, braking brake shoe are pressed on track and braked.After electromagnet power-off, under the effect of retracing spring, brake equipment resets.The method has been cancelled traditional brake cylinder, and it is more convenient to use.
Accompanying drawing explanation
Fig. 1 is constructional drawing of the present utility model;
1. brake brackets in figure, 2. track, 3. electromagnet, 4. braking brake shoe, 5. the braking arm of force, 6. hinged block, 7. retracing spring.
The specific embodiment
The utility model provides a kind of monorail crane electro-magnetic braking device, in order to make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, below with reference to accompanying drawing, the utility model is further described.
A kind of monorail crane electro-magnetic braking device, is made up of brake bracket 1, the braking arm of force 5, braking brake shoe 4, retracing spring 7 and electromagnet 3.Braking brake shoe 4 is hinged on one end of the braking arm of force 5, and electromagnet 3 annulars are enclosed in braking brake shoe 4 front ends, and the other end and the hinged block 6 of the braking arm of force 5 are hinged, and retracing spring 7 is fastenedly connected with hinged block 6.The retracing spring 7 tension braking arm of forces 5 in the time of normal operation, braking brake shoe 4 does not contact with track 2, in the time that needs are braked, electromagnet 3 is switched on, the electromagnet electrical current opposite direction of track 2 both sides, two electromagnet are different near one end magnetic pole of track 2, produce adsorption affinity, in the time that adsorption affinity exceedes retracing spring 7 pulling force, braking brake shoe 4 are pressed on track 2 and braked.After power-off, under the effect of retracing spring 7, brake equipment resets.The method has been cancelled traditional brake cylinder, and it is more convenient to use.
Those of ordinary skill in the art is under the enlightenment of the utility model patent; do not departing from the scope situation that the utility model claim protects; also can make the various deformation such as replacement, simple combination; within these all fall into protection domain of the present utility model, request protection domain of the present utility model should be as the criterion with claims.
