With the adoption of the electromagnetic braking device, the monorail crane can be reliably braked at any slope and position in a powered-off condition, so that the actual transportation security in a craning process is realized.
Description
Technical field
The utility model relates to a kind of brake equipment, relates in particular to a kind of electro-magnetic braking device that is used for monorail crane.
Background technology
The mechanization fully-mechanized mining working, owing to improve the needs of equipment safety performance, a large amount of use monorail cranies carry out handling; What the safety catch of existing monorail crane adopted is the disc type brake motor, in order to reach the effect that stops and braking, if the disc type brake motor damages; Be prone to cause brake failure; Monorail crane is just being glided along the gradient at the weight of handling the safety misadventure of driving takes place,, must a kind ofly can prevent this type of incident generation for guaranteeing the safe handling of monorail crane; The brake equipment of down all can actv. braking at power supply or the state that has a power failure, and do not have the report of this kind device in the prior art.
Summary of the invention
In order to solve the deficiency that exists in the prior art, the purpose of the utility model provides the electro-magnetic braking device that is used for monorail crane that all can effectively brake under a kind of ability realization power supply and the power down mode.
For achieving the above object; The technological means of the said employing of the utility model is: a kind of electro-magnetic braking device that is used for monorail crane; Comprise brake support frame and anti-explosion is electromagnetic iron, spring, pull bar, connecting rod, strut bar, tooth piece, anti-wheel, road wheel mounted thereto, said brake support frame is articulated on the monorail crane through road wheel; Said anti-explosion is electromagnetic iron is installed in the pull bar below, and said spring is installed in the top of pull bar; Said connecting rod one end cylinder lever connecting rod, an end connects the tooth piece, and middle and strut bar flexibly connects.
Further, said road wheel is provided with two, is positioned at the end of brake support frame.
Further, said anti-wheel is provided with two, is positioned at two road wheels middle part on the brake support frame.
Principle of work: anti-explosion is electromagnetic iron, spring, pull bar, connecting rod, strut bar, the aggregate erection of tooth piece are on brake support frame, and connecting rod one end is connected with anti-explosion is electromagnetic iron, and the other end is connected with the tooth piece; When the adhesive of anti-explosion is electromagnetic iron, connecting rod outwards rotates to an angle, and tooth piece and overhead hoist rack rails are thrown off; Overhead hoist normally moves; Like the outage of anti-explosion is electromagnetic iron, connecting rod rotates to an angle under the pushing tow of spring inwards; Make the engagement of tooth piece and overhead hoist rack rails, drg pins the purpose that monorail crane shipping unit hanger beams reaches safety arrestment.This drg and monorail crane shipping unit running part are combined, and can realize the failure-free two stage braking, have guaranteed the safe operation of monorail crane.
The beneficial effect of the utility model is: this device is through anti-explosion is electromagnetic iron, spring, pull bar, connecting rod, strut bar, the combination of tooth piece; Actv. has been realized all effectively braking under power supply and the power down mode; Guarantee the safe operation of monorail crane shipping unit, guaranteed production safety.
Description of drawings
Describe below in conjunction with the technical scheme of accompanying drawing the utility model.
Fig. 1 is the front view of the utility model;
Fig. 2 is the right elevation of the utility model.
Among the figure: 1, brake support frame, 2, anti-explosion is electromagnetic iron, 3, spring, 4, pull bar, 5, connecting rod, 6, strut bar, 7, the tooth piece, 8, anti-wheel, 9, road wheel.
The specific embodiment
A kind of electro-magnetic braking device that is used for monorail crane as shown in Figure 1; Comprise brake support frame 1 and anti-explosion is electromagnetic iron 2, spring 3, pull bar 4, connecting rod 5, strut bar 6, tooth piece 7, anti-wheel 8, road wheel 9 mounted thereto, said brake support frame 1 is articulated on the monorail crane through road wheel 9; Said anti-explosion is electromagnetic iron 2 is installed in pull bar 4 belows, and said spring 3 is installed in the top of pull bar 4; Said connecting rod 5 one end cylinder lever connecting rods 4, one ends connect tooth piece 7, and middle and strut bar 6 flexibly connects.
Further, said road wheel 9 is provided with two, is positioned at the end of brake support frame 1.
Further, said anti-wheel 8 is provided with two, is positioned at two road wheels, 9 middle parts on the brake support frame 1.
During use, brake support frame 1 usefulness road wheel hangs on the monorail crane shipping unit walking track, and combines as a whole with bearing pin with monorail crane shipping unit running part, during outage; Overhead hoist stops, and the drg safety arrestment is after the energising; Electromagnetic actuation, drg is opened, and overhead hoist normally moves.This drg utilizes the power supply of overhead hoist power supply, and operation is by the combined switch control of monorail crane shipping unit, and when promptly preparing to open drg, electromagnetism tooth piece drg is action earlier, and combined switch just starts other parts then; During safety arrestment, overhead hoist is outage earlier, and out of service, electromagnetism tooth piece drg safety arrestment then guarantees not damage under any state drg and monorail crane shipping unit rack rails.
Because this drg assembly part is few, simple in structure, connection and reasonable arrangement, it is easy that the adjustment connecting rod mechanism is installed, so Installation and Debugging are more convenient; This drg adopts electromagnetic actuation, unlimited brake tooth piece, then spring promotion brake tooth piece and rack rails engagement after the outage, and lock torque is big, and reliability is high, detection failure, mechanical component damage easily in the working service, it is quick that parts are changed in dismounting; After drg is installed; The monorail crane shipping unit has been set up the second road safety guard-safeguard facility, even the disc type brake motor damages braking failure; The monorail crane shipping unit can both be realized braking reliability in any gradient, position, makes goods handling process on the monorail crane shipping unit really realize transporting intrinsic safety.
The above; Be merely the specific embodiment of the utility model, be not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses; Can expect easily changing or replacement, all should be encompassed within the protection domain of the utility model.
