Description
Technical field
The present invention relates to a kind of flexible cage guide hoisting container unstability apparatus for evaluating and method suitable for vertical shaft hoist.
Background technology
Coal is the leading energy in China, and vertical shaft hoisting is the leading form of coal production.Mine shaft hoist system is undertaken
The vital task of lifting coal spoil, lower putting material, lifts personnel and equipment, is underground coal mine and the connection hinge on ground.
Mine shaft hoist system is mainly made up of elevator, steel wire rope, hoisting container (skip bucket and cage), cage guide etc..Elevator passes through steel
Cord dragging hoisting container raises and decentralizes in the wellbore along cage guide.Cage guide is the passage that hoisting container is up and transfers.By
Cause elevator, steel wire rope, hoisting container, cage guide in harsh carrying demand, the running environment of time-varying, complicated geological conditions
It is prone to failure with brake apparatus and safety guard, the serious accidents such as card tank, pulleying, crouching tank occurs, if rescue is not
In time, great casualties is caused.When accident occurs for mine shaft hoist system, it is necessary to rapid development scientifically and rationally rescue party
Case, under the secured premise of support personnel, rescue personnel is quickly reached the spot, and prevent second accident.
At present, for the rescue of mine shaft hoist system, escape and rescue trunk and deliverance apparatus are mainly have studied, is still lacked to accident
The unstability evaluation studies at scene.Mine rescue crane that patent authorization number is ZL 201320385546.4, patent authorization number are
ZL 201320500310.0 emergency escape rescue system and patent publication No. is that CN 201610074140.2 mine is vertical
Lifting system is rescued, different escape and rescue trunks is have studied and comes vehicle equipment and personnel.Patent publication No. is CN
201320460112.6 mine rescue wellhole acoustic image detection device can establish ground rescue personnel and down-hole trapped personnel
Bidirectional audio-video communicates.
When the accidents such as card tank, pulleying, crouching tank occur, hoisting container may hit extremely to cage guide is then parked in cage guide
In, steel wire rope, hoisting container and cage guide may be damaged correspondingly, cause now that pose of the hoisting container in cage guide can not
Lean on, it is difficult to judge the stable state of now hoisting container.Once hoisting container occurs to loosen or swung, when particularly rescuing
Loosen or swing, it will cause the life security of second accident, serious threat indicator of trapped personnel and rescue personnel.Flexible cage guide is
One of main cage guide form of current mine shaft hoist system.Thus, research one kind can promptly and accurately assess flexible cage guide and carry
The apparatus for evaluating and method of container instability status are risen, the security, reduction causality loss for raising accident rescue have important
Meaning.

sensor (16) side Parallactic angle and inclination angle are 0 °, the tension force of snub rope's tension sensor (15) is 0；(C) in the junction of boom hoist cable (5) and hoisting container (10) installation armored rope tension sensor (6), hold when being lifted When device (10) carried device is held, boom hoist cable (5) lower end is not subject to load, demarcation armored rope tension sensor (6) Tension force is 0；(D) the installation displacement transducer (13) at the top of hoisting container (10), benchmark is used as using the top of cage guide rope tensioner weight (11) Position, the height of demarcation displacement transducer (13) is the distance at the top of hoisting container (10) with cage guide rope tensioner weight (11) top；(E) by cage guide rope obliquity sensor (2), tension of cage guide rope sensor (3), snub rope's obliquity sensor (16), snub rope Tension sensor (15), armored rope tension sensor (6) and displacement transducer (13) are connected to control and monitor console (19)；Control and monitor console (15) applying power calculation formula of the cage guide rope i to cage guide rope sling (7) place at the top of hoisting container (10), water are provided based on mechanics principle Divide power equally and be designated as Fαi；Control and monitor console (15) is based on mechanics principle and provides snub rope j to caliper (8) place at the top of hoisting container (10) Applying power calculation formula, vertical component are designated as Fβj', horizontal component is designated as Fβj；(F) F that makes a concerted effort for being superimposed as the tail end tension force of all boom hoist cables (5) is designated as Fmain, by the reality of hoisting container (12) Gravity is designated as Gall, with reference to the cage guide rope i being calculated in real time to the applying power at cage guide rope sling (7) place at the top of hoisting container (10), Snub rope j is assessed such as the instability status of hoisting container (10) the applying power at caliper (8) place at the top of hoisting container (10) Under：Vertical direction1. work as Fmain≈Gall、Fβj' change in normal fluctuation range when, show boom hoist cable (5) carry hoisting container (10) whole longitudinal loads, control and monitor console (19) prompting boom hoist cable (5) is normal, caliper (8) does not clamp snub rope (14), Snub rope (14) does not carry hoisting container (10)；2. work as Fmain＜ ＜ Gall、Fβj' change when exceeding fluctuation range, show that boom hoist cable (5) does not carry hoisting container (10) whole longitudinal loads, control and monitor console (19) prompting boom hoist cable (5) failure, caliper (8) clamp snub rope (14), carried It is F to rise the longitudinal load that steel wire rope (5) and snub rope j undertake respectivelymainAnd Fβj'；Meanwhile Fβj' changing value it is bigger, show that corresponding caliper (8) more closely vises snub rope j, Fβj' changing value be less than Step up threshold value, show that corresponding caliper (8) has loosening risk；Horizontal directionIn the horizontal direction, FαiAnd FβjCollective effect is lifting steel in hoisting container (10) with the size and azimuth respectively relied on oneself Cord (5) synthesizes with the tie point O of hoisting container (10) show that horizontal direction is made a concerted effort FγAnd its azimuth γ, control and monitor console (19) are aobvious It is F to show that hoisting container (10) tilts along azimuth γ and tilts stressγ, mine shaft hoist system rescue when hoisting container (10) orientation Angle has loosening risk on γ directions；Meanwhile FαiChange exceed normal fluctuation range, show to produce the mutual of reality between cage guide rope i and cage guide rope sling (7) Extruding；Otherwise, show not producing actual mutual extruding between cage guide rope i and cage guide rope sling (7), lifted in respective party parallactic angle Container (10) has swing risk；Meanwhile FβjChange exceed normal fluctuation range, show to produce between snub rope j and caliper (8) and actual mutually squeeze Pressure；Otherwise, show not producing actual mutual extruding, the hoisting container in respective party parallactic angle between snub rope j and caliper (8) (10) there is swing risk.
