Description
Technical field
The present invention relates to a kind of hypervelocity autobrake systems of mine endless rope winch.
Background technique
In the prior art, the mode of braking of mine endless rope winch it is most common be insert pawl braking, be cylinder iron or other
Pawl brake block is inserted made of material, in wire cable rupture, brake block resists conveying track sleeper, makes winch by stiff resistance
It is out of service；Another relatively new type mode of braking embraces rail braking using jaw-type hydraulic, symmetrical based on combination
Wrench structure design is braked, by hydraulic device, caliper is controlled and embraces rail, braking is generated by the friction of caliper and rail
Power makes vehicle halt.
Above two mode of braking because the difference of its design principle has the advantages that respective and disadvantage: inserting grab mode of braking,
Simply, braking is reliable, but triggering mode is defective, malfunctions frequent occurrence, i.e., should trigger braking, however does not trigger,
Lose braking effect；Hydraulic rail-clamping mode of braking, with an improved triggering modes, triggering malfunction will not generally occur, still
Embracing rail mode of braking, often brake does not live vehicle under large-tonnage, the situation of high-speed cruising, causes brake failure.
Summary of the invention
The technical problem to be solved by the present invention is to how overcome the drawbacks described above of the prior art, a kind of mine endless rope is provided
The hypervelocity autobrake system of winch.
In order to solve the above technical problems, the hypervelocity autobrake system of this mine endless rope winch, including braking mechanism, it stops

Pulley, described wirerope one end be fixedly connected on quiet disk outer rim a little on, the other end across the part of fixed pulley and pulley disc restrict
It after slot, is fixed in pulley disc outer rim, the pulley disc is furnished with button power spring or reset spring, the button power spring or reset spring
The wirerope is tightened, and passes through the elongated central line for the wirerope being connected with quiet disk outer rim by chance on the axial line of quiet disk
A bit.
In use process, when endless rope winch wire cable rupture, car slipping occurs on the slope for the winch of rope traction,
Allow rev limit value when speed reaches, after quiet disk and Moving plate combination, quiet disk is either rotated forward, or reversion, can wirerope
Be entangled in its rope groove, tear wirerope, drive pulley disc and the deflection of horizontal pressure pin, discharge claw, claw under the effect of gravity, under
It falls and is inserted between the ground or sleeper of interorbital, to achieve the purpose that brake in time.
It is designed in this way, two-way centrifugal hypervelocity clutch brake trigger device pure mechanic structure is not required to electronic component, is not necessarily to
Power supply, high reliablity are not afraid of interference, can accomplish non-maintaining operation substantially, have clearly to the adverse circumstances of underground coal mine
Advantage, be worth in coal mine large-scale promotion application.
Main component uses stainless steel material, and wear-resisting, corrosion-resistant, anti-strike ability is strong, is unlikely to deform, and is suitable for rising and falling more
The severe transportation environment become.
As optimization, casing is also cased on the horizontal pressure pin of the vertical pivot two sides respectively, above-mentioned casing is fixed by bearing
On horizontal pressure pin, it can be rotated around horizontal pressure pin, the horizontal pressure pin holds the claw by above-mentioned casing.It is designed in this way,
Resistance is small when horizontal pressure pin rotates, and triggers sensitiveer
