Description
Technical field
The utility model is related to loading chute safety guard, the specially anti-skidding anti-fall device of loading chute.
Background technology
Traditional anti-skidding anti-fall device of quickly ration loading chute mainly uses the dynamic brakes of hydraulic wireline winch and quiet
Brakes coordinates makes drawworks brake to rise.Dynamic brakes is made up of control valve, brake valve and hydraulic motor.Brake stator system
By spring and interior outside friction disc, one-way clutch and brake hydraulic oil cylinder composition.It is on the one hand by controlling fuel feeding direction to change
Become the rotation direction of hydraulic motor, realize lifting of winch and decline, on the other hand when winch works overloadingly, can also pass through
It is subject to appropriate pressure to hydraulic motor forward direction, helping to brake.But when process is transported outward in actual production, it may appear that hydraulic pressure is twisted
Car steel wire rope is broken suddenly, control valve is damaged or situations such as friction plate failure, if the at this moment positive mistake of locomotive head, it will produced serious
Accident.Therefore design one kind can avoid loading chute when slinging because of winch cable fracture or control valve damage, friction
The anti-skidding anti-fall device that accidental falling situation occurs caused by piece failure is extremely necessary.
The content of the invention
The utility model solves existing loading chute easily because of car wire cable rupture, control valve damage, brake block failure
Loading chute accidental falling is caused etc. factor, and it is anti-skidding anti-there is provided a kind of loading chute the problem of shortage safety guard
Fall device.
The utility model is achieved through the following technical solutions：The anti-skidding anti-fall device of loading chute, including it is fixed on dress
Push-rod electric machine under car tower on steel I-beam, the output termination of the push-rod electric machine is fixedly connected with steady pin, the I-steel
Beam lower end is also arranged at intervals with multiple be oriented to and fixes hanger, and the push rod and steady pin of the push-rod electric machine are hung through fixation is oriented to
Ear is respectively fixed with two fixations towards loading chute side, on the steel I-beam of the lifting end both sides of the loading chute and wears pin
Hanger, the lifting pawl rear end of the loading chute is fixed with activity and wears pin hanger, and the activity wears pin hanger, fixation and wears pin hanger
On be provided with the pinned hole of mutual cooperation；Push-rod electric machine Stroke Control proximity switch is fixed with below the steel I-beam, it is described solid
Surely wear and push-rod electric machine is fixed between pin hanger starts control proximity switch, the push-rod electric machine Stroke Control proximity switch and push away
Bar electric motor starting control proximity switch is connected with push-rod electric machine respectively.When loading chute is sling, push-rod electric machine driving steady pin
Move transversely across and fixed wear pin hanger and pin hanger is worn in activity, it is ensured that loading chute surprisingly will not slide or fall.Fixed guide
Determine hanger to play the guiding role to the push rod and steady pin of push-rod electric machine, while ensuring the pin joint intensity of steady pin.Fixation is worn pin and hung
The pinned hole that ear and activity are worn on pin hanger cooperates, it is ensured that steady pin can accurately wear pin when loading chute is sling
Hole, plays pin joint effect.Push-rod electric machine Stroke Control proximity switch, accurate control push-rod electric machine stroke are installed on steel I-beam.
It is fixed to wear installation push-rod electric machine startup control proximity switch between pin hanger, it is ensured that installed in the lifting pawl rear end of loading chute
When activity is worn fixation of the pin hanger positioned at both sides and worn between pin hanger, start push-rod electric machine.
The pinned hole that the activity wears on pin hanger is long waist shaped hole.Activity, which is worn, opens long waist shaped hole on pin hanger, can increase
Pin joint it is fault-tolerant, it is to avoid fixed finger setting is inaccurate or loading chute lifting is not in place and the anti-fall failure of pin joint that is causing.
The utility model has advantages below：1st, device sets simple cheap；2nd, push-rod electric machine passes through Stroke Control
Switch and starting switch are accurately controlled, it is ensured that anti-drop function is reliable；3rd, ensure anti-fall with traditional dependence hydraulic wireline winch frictional force
Compare, reliability is higher；4th, device serious forgiveness is higher, also can be effectively anti-fall in the case of loading chute lifting is not in place, safety
Coefficient is greatly increased.
Brief description of the drawings
Fig. 1 is the utility model scheme of installation；
In figure：1- push-rod electric machines, 2- steady pins, 3- is oriented to fixed hanger, and 4- is fixed and worn pin hanger, and 5- activities are worn pin and hung
Ear, 6- push-rod electric machine Stroke Control proximity switches, 7- push-rod electric machines start control proximity switch.
Embodiment
The anti-skidding anti-fall device of loading chute, including the push-rod electric machine 1 being fixed under entrucking tower on steel I-beam, the push rod
The output termination of motor 1 is fixedly connected with steady pin 2, and the steel I-beam lower end is also arranged at intervals with multiple be oriented to and fixes hanger
3, the push rod and steady pin 2 of the push-rod electric machine 1 are through fixed hanger 3 is oriented to towards loading chute side, and the entrucking is slipped
Two fixations are respectively fixed with the steel I-beam of the lifting end both sides of groove to wear after pin hanger 4, the lifting pawl of the loading chute
End is fixed with activity and wears pin hanger 5, and the activity wears pin hanger 5, fixes the pinned hole worn and mutual cooperation is provided with pin hanger 4；
It is fixed with push-rod electric machine Stroke Control proximity switch 6 below the steel I-beam, the fixation is worn to be fixed between pin hanger 4 and pushed away
Bar electric motor starting controls proximity switch 7, and the push-rod electric machine Stroke Control proximity switch 6 and push-rod electric machine, which start, controls close open
7 are closed to be connected with push-rod electric machine 1 respectively.
When it is implemented, the pinned hole that the activity wears on pin hanger 5 is long waist shaped hole.
In use, when loading chute is sling, activity, which wears pin hanger 5 and is moved to two fixations, wears between pin hanger 4, touches
Push-rod electric machine starts control proximity switch 7, and push-rod electric machine 1 starts and promotes steady pin 2 being oriented to the guide effect of fixed hanger 3
Under, pass across to fix and wear pin hanger 4 and the movable pinned hole worn between pin hanger 5, three's pin joint firmly, is worked as fixation by steady pin
Pin 2 is moved to after specified location, touches push-rod electric machine Stroke Control proximity switch 6, and push-rod electric machine stops promoting.If now occurring
Situations such as fracture of loading chute hoisting wirerope, control valve damage, brake block failure, the utility model can effectively ensure that entrucking is slipped
Accidental falling does not occur for groove, it is ensured that the production safety below loading chute.When loading chute is put down, push-rod electric machine 1 shrinks, will
Steady pin 2 is extracted out from pinned hole, lose steady pin 2 it is spacing after, activity wear pin hanger 5 together with loading chute can smoothly under
Drop.
