Description
Technical field
Spiral unloading machine promotes large arm band-type brake anti-skid device, belongs to spiral unloading machine component device field.
Background technology
Under prior art, the brake wheel that spiral unloads lifting speed reducer does not possess anti-skid device, fixes promoting large arm axle by means of only band-type brake fastening brake wheel.Because load of unloading coal in machine long-term operation ageing equipment and winter is excessive, the rubber causing spiral to unload lifting speed reducer band-type brake expands with heat and contract with cold serious with large arm downslide phenomenon automatically.This phenomenon is as processed not in time, and not only can have a strong impact on winter large load and unload coal, affect boiler operatiopn, and can cause great harm to safety in production, consequence is hardly imaginable.So be badly in need of scientific research institution to research and develop a kind of anti-skid device, to solve the downslide problem that spiral unloading machine promotes large arm.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, and provide one can prevent spiral unloading machine from promoting large arm and glide, improve safety, spiral unloading machine easy to maintenance promotes large arm band-type brake anti-skid device.
The utility model solves the technical scheme that its technical matters adopts: this spiral unloading machine promotes large arm band-type brake anti-skid device, comprise brake wheel, the wheel outer ring of described brake wheel is provided with band-type brake, the outside of band-type brake and brake wheel is provided with fixed frame, the periphery of brake wheel is provided with two fixed legs perpendicular to periphery, fixed frame upper and lower end has vertical knock hole, be provided with T-shaped radius stay in knock hole, T-shaped radius stay is through upper and lower two knock holees and be stuck in two fixed legs.T-shaped radius stay is undertaken vertically to location by knock hole, and the shaft of T-shaped radius stay is stuck between two fixed legs, can limit fixed leg and brake wheel rotation, thus prevent brake wheel generation slide displacement.
Preferably, described band-type brake is looped around brake wheel bottom and sidepiece circumference.Band-type brake design arrangement mode make brakig force distribution evenly, improve braking effect.
Preferably, two described fixed legs are arranged at brake wheel axle center, and to be the center of circle circumferentially same; Two described fixed legs are symmetricly set on both sides, the center of circle.Two fixed legs with brake wheel distance of shaft centers from identical, brake wheel stressed evenly.
Two described fixed legs are symmetricly set on T-shaped radius stay both sides.
Preferably, two described fixed leg welding edges are on the periphery of brake wheel.Welding manner is more firm, and bearing capacity is stronger.
Preferably, two described fixed legs are fixed on the periphery of brake wheel by being spirally connected with bolt hole.Fixed leg adopts screw connection manner to connect, and can be convenient for changing, safeguard.
Compared with prior art, the beneficial effect that the technique scheme that this spiral unloading machine promotes large arm band-type brake anti-skid device has is:
1, can prevent from spiral unloading machine from promoting large arm to glide, improve safety: band-type brake is set, fixed frame, fixed leg and T-shaped radius stay, during use, T-shaped radius stay is undertaken vertically to location by knock hole, the shaft of T-shaped radius stay is stuck between two fixed legs, if there is band-type brake to loosen, brake wheel rotates, can by T-shaped radius stay backstop when two fixed legs rotate, can not continue to glide, fixed leg and brake wheel rotation can be limited, thus prevent brake wheel generation slide displacement, structure is simple, simple operation, solve and promote large arm and automatically to glide the major safety risks brought, safe and practical.
2, brakig force distribution is even, and braking effect is good: be looped around brake wheel bottom and sidepiece circumference, band-type brake design arrangement mode make brakig force distribution evenly, improve braking effect.
3 safeguard that replacing is convenient: two fixed legs adopt bolts, adopt screw connection manner to be connected, can be convenient for changing, safeguard with brake wheel.

Fig. 1 is the structural front view that this spiral unloading machine promotes the preferred embodiment of large arm band-type brake anti-skid device.
Fig. 2 is the structure right elevation that this spiral unloading machine promotes the preferred embodiment of large arm band-type brake anti-skid device.
Wherein: 1, T-shaped radius stay 2, fixed frame 3, band-type brake 4, fixed leg 5, brake wheel.
Detailed description of the invention
Fig. 1 ~ 2 are most preferred embodiments that this spiral unloading machine promotes large arm band-type brake anti-skid device, are described further below in conjunction with accompanying drawing 1 ~ 2 pair of the utility model.
With reference to accompanying drawing 1-2: this spiral unloading machine promotes large arm band-type brake anti-skid device, comprise brake wheel 5, the wheel outer ring of brake wheel 5 is provided with band-type brake 3, band-type brake 3 is looped around brake wheel 5 bottom and sidepiece circumference, brake rubber is provided with inside band-type brake 3, the outside of band-type brake 3 and brake wheel 5 is provided with fixed frame 2, and the periphery of brake wheel 5 is provided with two fixed leg 4, two fixed legs 4 perpendicular to periphery and is positioned at in the same circle that is the center of circle of brake wheel 5 axle center.Fixed frame 2 upper and lower end has vertical knock hole, and T-shaped radius stay 1 is through upper and lower two knock holees and be stuck in two fixed legs 4.Two fixed legs 4 adopt bolt, and welding edges is on the periphery of brake wheel 5.
Principle of work is as follows: during spiral unloading machine operation, and T-shaped radius stay 1 is extracted from fixed frame 2, after band-type brake 3 unclamps, promotes large arm rotation and drives brake wheel 5 to rotate, spiral unloading machine normal operation.
When spiral unloading machine stops operation, band-type brake 3 is held tightly, fix brake wheel 5, promotes large arm and fixes no longer action.For prevent the rubber of band-type brake 3 due to aging, expand with heat and contract with cold, the reason such as inefficacy occurs loosening phenomenon, cause promoting large arm and glide, more T-shaped radius stay 1 is inserted from fixed frame 2.If band-type brake 3 occurs loosen, brake wheel 5 rotates, fixed leg 4 synchronous axial system on brake wheel 5, when fixed leg 4 turns to T-shaped radius stay 1 position, by T-shaped radius stay 1 backstop, can not continue to glide, thus realize anti-skidding effect.
In order to safeguard change more convenient, the periphery of brake wheel 5 can offer bolt hole, fixed leg 4 by with bolt hole be spirally connected be fixed on brake wheel 5 periphery on, when fixed leg 4 deforms or ruptures, by backing out fixed leg 4, more can renew.Using method is same as the previously described embodiments.
This spiral unloading machine promotes large arm band-type brake anti-skid device and can apply on power plant's coal tripper spiral unloading machine, for the downslide accident preventing spiral unloading machine lifting large arm from causing because of mechanical reason, reduces operating risk, guarantees production safety.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
