Description
Technical field
The invention belongs to the anti-fall technical field of deep-well lifting system, and in particular to a kind of permanent-magnet buffer and tradition machinery
Deep-well lifting system intelligence anti-drop method and device that formula catching device is combined.
Background technology
In recent years, as Coal Industrial is developed rapidly, requirement of the China to safety of coal mines is also increasingly stricter, but mining industry
It is still at present one of high risk industries.Wherein, deep-well lifting means is the visual plant for connecting underground and ground, once deep-well is lifted
There is pendant formal matter event in system, also a series of along with equipment damage, production disruption, schedule delays etc. while causing casualties
Problem, has a strong impact on being normally carried out for mining production activity.During deep-well lifting system works, because boom hoist cable is disconnected
Split, operate against regulations, safety devices imperfection, overhauling not in place, safety devices maloperation, the reason such as control system failure and may
Cause pendant formal matter event.Now, anti-drop system be hoisting container can uniquely steadily stopped, safeguard work personnel and transporting equipment
The effective means of safety.Therefore, a kind of safe and reliable anti-drop system is designed for reducing the generation of pendant formal matter event, improving colliery
Industrial Security has important practical significance.
Catching device is installed additional in deep-well lifting system, be the main security safeguard measure taken lifting means both at home and abroad.
With the promotion and application of all kinds catching device, the generation of accident of mine disaster, but mine are effectively reduced to a certain extent
Lifting means accident is still present.The catching device that current all kinds of mines commonly use has three kinds, respectively FS types catching device, GS types
Catching device and BF type catching devices.These three catching devices are all by the catching device on hoisting container, on derrick
Buffer, snub rope, check band, connector, this several part of take-up device constitute, and the difference of three kinds of catching devices is mainly catching device
Difference.
FS type catching devices are that Shenyang Coal Mine Design research institute designs according to Soviet Union's " cage dog ", using lever
Sliding wedge type arresting agency, after boom hoist cable is broken suddenly, spring elongation guides two pieces of chocks to transport upwards by transmission mechanism
It is dynamic, check band is adjacent to, there is frictional force between chock and check band, frictional force constantly increases up to catching check band completely, most
Realize that hoisting container is braked eventually, have the advantages that to be active in one's movements, arrest relatively reliable, but it is more difficult to arrest rear recovery process, malfunction
Make more, and complex structure, conduct oneself with dignity it is larger.
GS types catching device uses eccentric lever brake shoe formula arresting agency, after boom hoist cable is broken suddenly, spring elongation,
Eccentric lever is set to rotate by transmission mechanism, two brake shoes are gradually approached up to stuck main brake rope, realize braking effect,
Have the advantages that deadweight is relatively light, it is easy, safer reliable to reset, but serious wear is, it is necessary to regularly replace parts.
BF types catching device using rolling friction wedge shape arresting agency, after boom hoist cable is broken suddenly, shrink, and leads to by extension spring
Transmission mechanism is crossed so that two pieces of sliding wedges while moving and being adjacent to check band, the frictional force produced between chock and check band makes upwards
Chock continue up, until completely firmly grasp check band, realization the hoisting container that falls is arrested, with simple structure,
From heavy and light, arrest reliable, convenience that reset, safety coefficient high, parts long service life, it is easy to maintenance the advantages of, but braking
During due to effect of inertia, hoisting container can produce significant shock, and runaway accident (Winch control system failure) is occurring
Shi Wufa produces effective brake action.
Above-mentioned several catching devices are brake shoe or chock is adjacent to check band by machine driving, using producing between the two
Frictional force realize braking effect, belong to machinery and arrest, larger, tension spring fracture of wearing and tearing, braking procedure vibrations are larger and system
The problems such as dynamic distance is more long.
Current magnetic force retarder is used in the brakes of heavy truck, including electromagnetic retarder and permanent-magnet buffer
Two kinds.
Electromagnetic retarder is that, in a kind of more magnetic force retarder of automotive field application, magnet coil is arranged on stator,
The excitation and braking moment size of electromagnetic retarder are controlled by controlling the power on/off and size of current of stator winding, with knot
Structure is simple, and production cost is not high, and braking moment scope is wide, and the response time is fast, and operating noise is small, and braking moment is adjustable, low failure
Rate, the advantages of easy to maintenance；But electromagnetic retarder is that by magnetic excitation coil, coil heating is serious, easily cause heat fading (by
Show in braking time is more long or braking moment declines compared with braking moment caused by making coil heating greatly, braking distance is elongated
As), high energy consumption needs to charge for a long time after battery repid discharge, and recovery time is more long and the frequent high power discharge meeting of battery
Service life is reduced, maintenance cost, inadequate energy-conserving and environment-protective is increased.
Permanent-magnet buffer is to produce magnetic field using itself intrinsic permanent magnet, and permanent magnetism body position is controlled by machine driving
To control excitation path, so as to control the change of braking moment, the problems such as big electromagnetic retarder energy consumption, heat fading is overcome, forever
Magnetic-type retarder uses high performance Nd-Fe-B permanent magnet excitation, and without power supply, permanent magnet will not generate heat, be declined in the absence of heat in itself
Move back phenomenon, it is not necessary to be equipped with battery, easily realize lightweight, excitation stabilization, braking moment stabilization.
Current magnetic force retarder is more in transportation application, in the market do not occur also by magnetic force retarder with it is anti-
The anti-fall device and method that pendant device is combined carry out safeguard protection to deep-well lifting system.
