Description

Movable chassis type cage bearing device for supported joint of cage vertical well

Technical field

The present invention relates to the mine vertical shaft carrying device for cage such as a kind of colliery, is a kind of movable chassis type cage bearing device for supported joint of cage vertical well specifically.

Background technology

Colliery both domestic and external or metalliferous mine adopt the vertical development scheme to be in the great majority, and transport personnel, material, the large multiplex vertical cage hoisting way of equipment to aboveground down-hole with the mine of vertical exploitation, most of cage shafts adopt mine car, flat truck carrying material installation, be also the inside and outside rail docking of cage, the mode of rail transportation.Minority adopts rubber-tired cart to transport, and is also the inside and outside trackless docking of cage, uses the trackless transportation mode.

So-called carrying device for cage, the cage that promotes exactly is stopped at well head or shaft bottom level, and catching device can be linked up outside track in cage, and can will be stopped at the outer vehicle of tank and push in tank, or the vehicle in tank is pushed to outside tank.Existing have two states by vehicle basically to the in-built unloading manner of cage:

1. suspention loading and unloading: cage is to be suspended on Winding rope, and steel cable is elastic component, along with increase (dress) or the minimizing cage of load can sink or rise.Along with mine shaft depth increases, this elasticity is sunk or is risen and also can strengthen.Generally the at full load elastic elongation can reach 0.6 ‰ left and right of well depth, i.e. a km deep-well, and elastic elongation can reach 0.6 meter left and right.

Winding rope is except elastic elongation, also has plastic elongation, the plastic elongation amount is about 5 ‰ of well depth, progressively to tend towards stability after elongation in the process of about half a year, cage is to be connected by main rope suspension gear with hoisting rope, suspension gear is that the plastic elongation measure (passing through hydraulic actuating cylinder) of elimination is arranged, but is not automatically to eliminate plastic elongation at random but reach a certain amount of to eliminate by manual operation.In daily production process, the impact of a little plastic elongation is just arranged like this.In addition, stopping in addition the tank error, is that machine stops or manual operation all has the tank of stopping error, generally gets ± 50 ㎜.

In lifting process, acceleration, constant speed, deceleration, starting, parking are all that the indicated altitude according to depth indicator operates, and point station has two kinds of situations:

A. point station also relies on depth indicator to stop, well head like this, and the actual point station in shaft bottom is an individual parameter, with the steel cable elastic elongation, plastic elongation and to stop the tank error relevant.Elastic elongation and the loading size of living, well depth are proportional, and plastic elongation is with steel cable work-hours length and transfer the rope cycle relevant, and stopping tank error and depth indicator error etc., to reach the skilled operation degree relevant.

B. point station stops according to shaft bottom actual " tank position signal ".Namely install on the stock of shaft bottom by " tank position signal ", can send the signal that puts in place when cage arrives the shaft bottom assigned address, winch is power-off brake immediately, and the shaft bottom cage is no matter be that also namely no matter how many elastic elongations is for heavy duty, underloading or zero load like this, during plastic elongation, what are all stopping a train at a target point at every turn.Though be stopping a train at a target point, stop that the tank error still has.

2. fixed high loading and unloading: catching device can limit the lifting of cage in handling process, and namely catching device can bear the power downward or upward of loading or off-load, makes the inside and outside track basic horizontal docking of tank, and whole handling process is in stable state, does not rise also and does not fall.

In the modern times, most mines all adopt frictional geared winch to promote, and its characteristics are exactly can not " weightlessness ", " weightlessness " will cause Winding rope skidding on winch drum, cause depth indicator that error is arranged, will make troubles, even cause a serious accident.

The loading of living can lose.The weight such as cage deadweight, Winding rope weight and tail rope become dead loading.Dead loading does not allow to reduce.

Its basic demand of various catching devices can not cause weightlessness exactly, and namely no matter be to adopt suspention loading and unloading or fixed high loading and unloading, carrying device for cage all can not allow dead loading reduce.

In general, in the double-hook hoisting situation, after parking, well head cage and shaft bottom cage should load and unload simultaneously, but that is to say that the rear well head of parking and shaft bottom cage all will be in the catching device opereating specifications.

One promotes circulation and comprises clean lifting time and stop time.Because maximum lift speed improves constantly, more than some wells reach 15m/s, so the time that only promotes proportion in promoting circulation has the trend of dwindling.And the stop time just comprises the switching carrying device for cage, open and close the time of other behaviour's vehicle devices etc. (safety door, stop device, car puller etc.), backwardness due to catching device, grasp the inharmonious of each equipment room of car, stores van, flat truck particularly iant flat truck (transporting the heavy fully-mechanized mining equipments such as the fully-mechanized mining working surface hydraulic support) stop time in when loading and unloading long.As the Coal Mine Design regulation and stipulation, the individual layer tank transports material galassing wooden handcart can be by 40 seconds, and bilayer can be by 88 seconds.At general mine, and only the lifting time has reached the ratio of 1: 1 for this, in fact, stop time can substantially exceed design regulation, as sometimes stopping the tank error and exceed the scope of accepting because plastic elongation adds, will the give a signal secondary to tank (promote at a slow speed or transfer), even once will be repeatedly to tank in loading and unloading.So just substantially exceeded the time of code requirement, made the stop time surpass the clean lifting time, made production efficiency low, so should improve catching device, particularly improved the catching device of deep-well, large cage, reduced the stop time, enhanced productivity.

In existing cage vertical, the shaft bottom carrying device for cage roughly has following several types:

(1) cage chair: its basic structure is for respectively arranging the track of one section activity at the two ends of shaft bottom cage, with the track inside and outside the connection tank, movable track is take tank outer junction as fulcrum, a place that integrates with in tank can move up and down certain altitude, and the height that the cage chair rocking arm can be regulated is greater than shaft bottom Winding rope elastic elongation, certain plastic elongation and cage stops tank error sum.The entry side rocking arm has allowed ascents and descents, goes out the car side and has generally only allowed descending, and entry side gradient general control goes out car side descending general control at 10 ° at 5 °-6 °.

Cage chair belongs to suspention loading and unloading, relies on the depth indicator parking of reaching home.Its common structure as shown in Figure 1.Its advantage: when 1. loading and unloading load, cage is in suspended state all the time, and dead loading can be not weightless.2. in cage when operation,, the rocking arm of cage chair is to lift beyond safe limit, stops just can fall after tank, so when running into Volume and the unforeseen circumstances such as overrunning, can not bump and cause the accident with cage.But there is following shortcoming: 1. in handling process, unexpected increase or the minimizing of loading alive, not only produce elastic elongation or shortening, also can make steel cable produce up and down elasticity concussion, particularly well is darker, and the loading of living is heavier, and rocking arm is longer, concussion harm is more serious, even has because the rocking arm concussion makes the accident that mine car slides down on rocking arm to occur.Some cage chair has just configured hydraulic buffer cylinder, and certain effect (as shown in Figure 1) is arranged, but there is increase the stop time, heavy duty, the difficult adjusting of underloading.2. maximize along with mine, deep-well, the shaft bottom cage chair more and more becomes heavy wares, expends power also large, and accident and maintenance capacity all increase.3. the stop time relatively long the rear cage chair that just can fall because tank puts in place plays rocking arm again after having loaded and unloaded, as the loading and unloading of double-layer loading or multilayer, every layer all will be risen and fallen once, all more than 3000 ㎜, this has just increased the go-cart stroke to heavy rocking arm.Not only the car puller structural weight increases, and the stop time of go-cart stroke and return of stroke has also increased.

Rocking arm is regulated height and can only be comprised limited plastic elongation and stop tank poor (elastic elongation must comprise entirely), in case plastic elongation or stop the tank error and exceed, rocking arm can not adapt to, will secondary to tank, can see in production that once loading and unloading are for several times to tank.

When making cage chair as carrying device for cage, the upper and lower personnel rocking arm that also must rise and fall, otherwise personnel can't pass in and out, even only have 1 people, heavy rocking arm also will rise and fall.

(2) card canister: the card canister abroad mine use more, domestic have a small amount of mine in use, its basic system and use procedure are as follows:

Four projections are arranged on every layer of chassis of cage, adopt fixed high loading and unloading, stop by tank position, shaft bottom signal.Corresponding each projection, be provided with two groups of claws, i.e. upper clipping claw and lower claw on Jing Liang.Have four upper clipping claws, four lower claws are used respectively eight slight type Driven by Hydraulic Cylinder.When cage arrives the shaft bottom, adopt stopping a train at a target point, be parked in when in tank, outside track is substantially to mean place, stretch out simultaneously through operating eight claws, spacing between upper and lower claw has ± gap of 50 ㎜ projection, namely cage have ± 50 ㎜ stop the tank error.Outside track has ± discrepancy in elevation of 50 ㎜ in tank, directly passes in and out car and has any problem, so the card canister is set, generally still must configure the cage chair (see figure 2), when load and unload lighter vehicle, uses cage chair; During the loading-unloading heavy flat truck, cage chair and card canister use simultaneously.Because when using the card canister, elevator system shaft bottom employing stopping a train at a target point, the elastic elongation of shaft bottom side hoisting rope and plastic elongation all will be married again the well head side like this, and the well head catching device is wanted and can be adapted to.

When loading on the heavy wares flat truck well to the shaft bottom when slack tank, the heavy flat plate car is pushed into cage through rocking arm, cage is pressed on four lower claws by projection because of elastic elongation, and at this moment through operation, rocking arm lifts, upper clipping claw is regained, send out and promote signal, cage namely upwards rises to well head, after carrying on tank, through operation, regain lower claw again.To the shaft bottom, first cost cage chair when heavily loaded cage, start car puller, after the galassing wooden handcart is released cage, also eliminate because of the hoisting rope elastic elongation and shorten.Cage is crushed on upper clipping claw, and at this moment, rocking arm is first lifted in the shaft bottom, the while give a signal, and the short range of cage low speed is transferred, and when waiting cage all to break away from upper clipping claw, regains upper clipping claw through operation, and give a signal promotes, after waiting tank to walk, the lower claw of operation withdrawal.

If fill not only but also unload, wait loaded and unloaded after, if claw under tank pressure is regained upper clipping claw, give a signal promote to be regained lower claw; As after having loaded and unloaded, the tank pressure upper clipping claw, give a signal falls cage slowly after the disengaging upper clipping claw, regains upper clipping claw, then give a signal promotes claw under rear the withdrawal.

The advantage of this card canister: 1. in loading and unloading operation, cage load or off-load after, the concussion that can not produce suitable amplitude, this is maximum advantage.Namely in deep-well, guarantee that it is the advantage of card canister maximum that heavy wares loads and unloads reposefully.2. in loading and unloading operation, concerning hoisting rope, the loading of just living of variation, dead loading can " weightlessness ".The structure of 3. blocking canister is not too heavy, moves under no-load, and propulsive effort is less.Because cage chair can be regulated high reducing, the cage chair structure can be alleviated.

Its shortcoming is: 1. for simple cage chair, many a set of equipment want more loaded down with trivial details in operation, and the stop time will increase, and when particularly transporting heavy wares to the down-hole, cage can press to upper clipping claw, can be many action of downward " sink tank " of a cover.2. the elastic elongation in shaft bottom, plastic elongation will be married again on the well head catching device, so well head is regulated high will the increase, rocking arm will increase, weight will increase.When 3. going up the servant, also will operate cage chair increases the stop time.

(3) prop up the tank machine: a tank machine is generally to aim at the heavy wares flat truck to use, general material, and the equipment car, spoil mine car etc. is still used cage chair.Every layer, the cage of accepting with tank machine has two-layer disk body, i.e. so-called dead chassis, false bottom dish.Dead chassis and column connect together, and each layer dead chassis, take over a business and column formation cage body.Each layer false bottom plate rail is on dead chassis, and the false bottom dish is covered with rail, and is paved with steel plate (people stands), and dead chassis slightly is longer than at two ends, in order to the claw support.The cage body is in suspended state all the time, and cage stops according to depth indicator.

Prop up the tank machine and form (see figure 3) by claw, guide rail and hydraulic drive cylinder.Four groups of claws are generally arranged, four groups of guide rails, four groups of hydraulic actuating cylinders form a tank machine of a cage, also available two groups of hydraulic actuating cylinders drive four groups of claws by crossbeam and move on four groups of guide rails, the curved shape of guide rail, can hold up the false bottom dish when claw is lifted, when falling, claw outside guide rail is down to gauge, does not affect tank up and down.

Hydraulic cylinder travel is greater than elastic elongation, plastic elongation and stops tank error sum.

When cage transports the heavy wares car to the shaft bottom level, press depth indicator and stop, be stopped at below rail level.This comprise steel cable elastic elongation, plastic elongation, give and stay the gap, stop the tank error.The operation hydraulic actuating cylinder lifts the false bottom dish, and the rail level on the chassis is just in time faced with the tank outer rail and put down, and lifts the false bottom dish, and also and then lift on dead chassis, but only rise elastic elongation, also has an intersegmental gap between two chassis.That is to say to give and stay gap and plastic elongation and stop the tank error, even plastic elongation is zero with stopping the tank error, stay the gap because giving, two chassis can be not inseparable yet.

When transporting on the heavy wares car well down to the shaft bottom when cage, pressing depth indicator stops, be stopped at position more shallow under rail level, because the false bottom dish is conducted oneself with dignity elastic elongation seldom, only comprise and give the distance of staying gap, plastic elongation and stopping the tank error, after the operation hydraulic actuating cylinder lifted the false bottom dish, two-layer chassis spacing was substantially the same when going into the well with heavy wares, be still to give and stay gap and plastic elongation and stop the tank error, just stop the tank error slightly different at every turn.

After the false bottom dish lifts, just can grasp car, equipment car in tank is released outside tank, or push the external device car in tank or simultaneously tank external equipment car is pushed, the equipment car is released in tank, namely replaces completed loading, can operate a tank machine, the false bottom dish is fallen, then is promoted.If the cage two ends of tank machine can establish originally that trapped orbit joins, so just regardless of what vehicle, heavy type, light-duty tank machine, the light flat plate car in this way all used, or empties, dislike complicated operation, the stop time lengthens, be not as light as cage chair, so just establish two kinds of catching devices, existing cage chair has again a tank machine, but cage chair is only accepted separately the light equipment car, its adjusting height can reduce, and rocking arm can shorten, and weight can alleviate.

The advantage of tank machine: 1. dead loading can be weightless during loading and unloading.2. prop up tank machine and claw and be parked in beyond gauge, and be stop tank just begin later on the action.Run in lifting and to cross Volume, when the situation such as overrunning, can not crash with cage.3. during loading and unloading and hoisting rope throw off, can not produce the elasticity concussion.4. secondary is less to the tank chance.Its shortcoming is: 1. prop up tank machine hydraulic cylinder travel except comprising heavy wares elastic elongation, plastic elongation, giving and stay the gap, stop the tank error, also to comprise claw and become rail desired height to gauge, so stroke is longer, the weight of holding in the palm is heavy wares car (fully mechanized mining supporter of large-scale mine just can reach 30t-40t), also heavier, thus light-dutyer equipment car, stores van, the tank machine loading and unloading of the use such as ore car are wasted with regard to seeming heavy, so must cage chair.Just have two kinds of catching devices to share situation, equipment is huger, and maintenance capacity is also larger.2. every layer of cage disk body, except dead chassis, add one deck false bottom dish, compares with common cage, and structure is slightly complicated, and highly slightly large, weight is slightly heavy.3. the stop time will increase (～8 seconds-20 seconds) to some extent than simple cage chair.4. cage chair also will be employed during personnel in the up and down.

(4) carrying device for cage of similar tank machine

As Chinese invention patent application " double-compensation locking automatic rotation layer exchanging cradle and pot supporting method " (application number 200910028725.0; Application publication number CN101704467A) disclosed carrying device for cage (seeing this patent specification accompanying drawing 1), has the rotary type claw, claw has driver train and buffer gear, the galianconism cage chair is arranged at top; rocking arm and claw interlock; cage should stop according to depth indicator, and heavy tank can be parked in below the track cross level of shaft bottom in this way, and operation driver train; claw lifts cage; rocking arm falls is simultaneously linked up outside track in tank, namely can grasp car; operate driver train after completing again and reverse; rocking arm is lifted, and claw falls, then give a signal promotes.

Contrast with a tank machine: a tank machine claw stroke will comprise elastic elongation, gives and stays the gap, stops tank error and claw and becomes rail to the outer height of gauge, and it is holder year stroke effectively, and actual is a parameter.Be exactly a parameter because stopping the tank error, generally change in ± 50 scopes.Moulding elongation is also parameter, and the plastic elongation of newly restricting increases fast, and old rope increases little.Tend towards stability after generally using half a year, plastic elongation goes to zero.No matter how change, its effectively holder to carry a stroke be all sure greater than elastic elongation, but the just false bottom dish that holds up due to claw, the loading of living.False bottom dish and cage are thrown off, the loading of just living that main rope loses, and dead loading can " weightlessness " in any situation.

What this equipment claw held up is whole cage, so-called " giving young employees remedial-courses in general knowledge and vocational skills " compensate namely that elastic elongation compensates plastic elongation simultaneously and in fact the effective travel of claw need greater than elastic elongation, maximum plastic elongation and maximum are stopped tank error sum.The effective travel that holds up in any case that is to say holder power greater than the loading of living generally all greater than elastic elongation, and namely some dead loading is held in the palm and on main rope " weightlessness ", this is unallowed to friction winder.

Due to the uncertainty of stopping tank error and plastic elongation, each " weightlessness " that promotes, also not wait, slight " the skidding " of even causing due to weightlessness, and it is little and be difficult for discovering to cause the depth indicator error, elastic elongation is held up not, after behaviour's car, open the rocking arm hoisting rope and can shorten suddenly and shake.

The advantage of this device: 1. the elasticity concussion generally can not occur.2. claw and rocking arm be in normally open, and tank puts in place and stops just holding up and falling afterwards, thus when crossing Volume in this class accident that can not bump.Its shortcoming is: 1. ask the tank stroke generally greater than elastic elongation, this is almost that each loading-unloading vehicle all can make main rope section weightless, causes " skidding " chance more or less, is that friction winding is unallowed.The maximum picking-up power design of this equipment reaches 1000KN, and (the most about 300～400KN), residue holds up sizable dead loading and the loading present stage of living is so not large.When 2. opening claw and rocking arm, cage will sink a certain amount of mostly at every turn, on occasional, contracting is a certain amount of, almost not have and neither sink to also not rising as you were, this just illustrates that this catching device most applications in handling process can make cage weightless, also there is a few cases can not hold up loading alive fully, illustrate that also this device will emphasize that buffering discharges cage, because do not cushion, steadily release also can cause the harmful concussion of elasticity, so each loading and unloading first cushion lifts claw, slowly put down claw again, could promote, the stop time lengthens certainly.3. because rocking arm and claw are that interlock is held together, can not separate individual drive, even light tank, slack tank is gone into the well or upper well, also will with the same program of heavy tank, enable can not economizing of province's stop time.4. in this device, rocking arm is arranged, have claw and holder power huge, surpass the loading of living, so the consumption of hydraulic-driven energy is larger, also have damped cylinder, load also quite large, work under the heavy load of being everlasting, maintenance capacity is also large.

(5) card tank buffering cage chair

A kind of a kind of equipment that produces harmful concussion for cage chair in the loading and unloading of shaft bottom and design, as Chinese invention patent " a kind of steady tank mechanism and steady tank arrangement that utilizes vertical cage to promote " (patent No. 200810020506.3 is authorized publication number CN100532240C).The crossbeam that connects two steady tank arms with the two steady tank arms that are similar to the cage chair rocking arm, be hinged on the beneath vertical cushion cylinder (or cylinder) of crossbeam, and the steady tank of the so-called catcher formation mechanism that is fixed on steady tank arm, the latch that catcher uses small cylinder (or cylinder) to drive exactly.Adopt stopping a train at a target point, no matter be heavy ullage tank, by tank position signal, tank is stopped at the position of rail level maintenance level docking inside and outside tank, handle small oil tank, drive latch and insert the pin hole of opening on the cage chassis and pin the cage position.Two kinds of embodiments are arranged:

Scheme 1(sees Chinese invention patent " a kind of steady tank mechanism and steady tank arrangement that utilizes vertical cage to promote " Figure of description 5): conventional cage chair is set and steady tank arrangement two complete equipments use jointly.Tank puts in place and puts down rocking arm after catcher in the steady tank of rear use mechanism pins cage again, carries out the loading-unloading vehicle operation.After operation is completed, first lift rocking arm, assistant cylinder plays buffer action, slowly discharges downward or upward elastic elongation.After release is completed, should extract latch out, give a signal promotes.

Scheme 2: separately do not establish cage chair, just lay a railway track on steady tank arm, paving steel plate, turnover car, upper servant.

it is exactly with elastic elongation that fixed point is stopped tank, plastic elongation imputes to the well head catching device, but stop that the tank error still has, if the pin hole internal diameter on the cage chassis is only than the large 4-5mm of latch external diameter, may stop after tank to insert not inlet hole because of the error latch, need secondary to tank, even repeatedly repeatedly tank also is not easy to insert, just need the pin hole internal diameter larger than latch external diameter, generally stopping the tank error gets ± 50mm, namely want the hole internal diameter than the large 100mm of latch external diameter, like this in scheme 2, the inside and outside orbital plane error of tank can occur between ± 50mm repeatedly, the turnover car is impracticable under such discrepancy in elevation, so scheme 2 is worthless.Scheme 1 is to be overlapped on the tank inner orbit with rocking arm independently, eliminates the discrepancy in elevation of docking orbit with the little uphill/downhill of rocking arm.So in 2 schemes, it is feasible only having scheme 1.

Its advantage is: 1. can absorb most of harmful elasticity concussion.2. can not make cage weightless.3. crossing Volume can not bump.Shortcoming: 1. absorb the elasticity shortening of Winding rope or elastic elongation and card canister with assistant cylinder up and down cushion stroke cage is stuck on the claw of rigidity up and down, with the lifting of steel cable itself or put down the release elastic elongation and contrast:

A. block cage shoe simple in structure, simple to operate, it is relatively huge that assistant cylinder adds trap structure, trivial operations.

B. the card canister is short the stop time, and assistant cylinder lengthens relatively.

C. maintenance capacity card canister is few, and assistant cylinder is relatively large.

2.. fix a point to stop tank owing to adopting, elastic elongation, plastic elongation will be married again the well head catching device, makes it to regulate high the increasing, and structure strengthens, and weight also increases the weight of.

In sum, cage vertical catching device has multiple basic version and improves variation pattern both at home and abroad, but along with well depth is constantly deepened, the km well often occurs, load continues to increase, the above fully mechanized mining supporter of 40t will transport by cage, just shows the not enough of shaft bottom carrying device for cage and falls behind: 1. often many complete equipments mix and use, and add card canister, cage chair as cage chair and add a tank machine, cage chair and add and ask cage shoe, cage chair to add two kinds of equipment of heavy wares needs such as card tank assistant cylinder to be used in conjunction with.Light equipment can only use cage chair, and some equipment also wants two kinds of equipment jointly to use, and it is loaded down with trivial details that this just makes operating sequence increase, and the equipment kind increases, and maintenance increases.2. the stop time increases, and the increase factor has: a, equipment increase, and stretching out of every kind of equipment regained and all wanted the time.B, deep-well elastic elongation increase.Some equipment is that the action with equipment absorbs elastic elongation, so slowly, the action of long stroke will increase the time.C, deep-well plastic elongation stop the tank error, and the uncertain factors such as depth indicator error are not easy to control, and tank puts in place rear or exceeds in operation the scope of accepting, need to be to tank, even repeatedly to tank.3. weight of equipment increase, energy consumption increases, and needs to live more than loading 40t more than three meters as rocking arm, regulates high 1m above (as propping up tank machine etc.), and maximum separate unit power reaches 20-30kw.

How to develop a kind of novel catching device, its advantage of absorption is abandoned its shortcoming in existing multiple pattern, integrates to draw:

1. the action that need not install for elastic elongation absorbs, and with the rising of elevator system, transfers to discharge.

2. load and unload without suspended state, and with the loading and unloading of rigidity holding state, avoid the harmful concussion of elasticity, steadily load and unload.

3. without the common cage on individual layer chassis and with the double-layered base plate cage with the false bottom dish.The one, can guarantee that dead loading is not weightless.The 2nd, only and live load come into contacts with and avoid energy consumption over live load.

4. do not adopt the card cage shoe with the gap, up and down because in tank outside track can not be fully to flat, also to lean on the cage chair overlap joint, do not adopt the holder cage shoe that stops after the tank holder tank that rises yet, like that not only consumed energy but also time-consuming, and adopted dynamically fixing holder cage shoe, holder cage false bottom dish.For preventing Volume or Chao Su Dun tank, guarantee safe operation, holder cage shoe (claw) is got normal retracted state, only stretches out transferring the circulation end section of the creeping utmost point short time, as run into and cross at full speed Volume, general speed and cross Volume, reach home at a slow speed but be not the constant speed situation such as creep, the holder cage shoe does not stretch out; After stretching out the holder cage shoe as the section of creeping, cross rest point and do not stop, continue to cross Volume with creeper speed, can the automatic drawing back claw, put down the false bottom dish.Promoting cycle start, little gap (60-80mm) is passed through with low speed in dead chassis, between elastic elongation and two dishes, cushion rubber is buffering, mention the false bottom dish, claw is regained, no matter so on carry or transfer circulation, it is few that claw stretches out shared height ratio, the various danger that may occur all take technical measures to avoid.

5. do not adopt and stop after tank with the catching device of large power plant with load folding and unfolding heaviness, transfer circulation end and cage interlock extending apparatus and adopt, promoting the cycle start retraction mechanism, dynamically folding and unfolding, stop can grasp immediately car (loading and unloading) after tank, the shared stop time of catching device is zero.

6. the power resources of cage and catching device interlock are in the gravity of cage.Do not round the gravity of a cage, a gravity with false bottom dish and live load.Generally, stretching out of claw all carried out at no load state with reclaiming, and is very little so expend gravity, but also do not take from dead loading, guarantees not weightlessly, only takes from loading alive.Descending when crossing Volume with creeper speed, may be with heavy lift, even because adopt the above load of rolling structure 40t, expend also hundreds of jin level just of gravity, there is this moment the above load pressure of 40t on the false bottom dish, the gravity source is not a problem.

Desirable catching device should reach following effect:

1. weight equipment no matter, all use such covering device, all uses combined operation, without manual operation.

2. various vehicles all in tank outside track really flush and be to load and unload under the rigid support state.Steady safety.

3. the shared stop time of catching device is zero.For efficient the lifting paved the way.

4. separately do not establish actuating device, the interlock power consumption is also minimum, realizes the low-carbon (LC) catching device.

5. weight is the lightest.

6. carry people's signal and send, claw can not be stretched out automatically, need not overlap and reclaim cage chair, puies forward people's efficient and can improve yet.

At the bottom of movable chassis type cage bearing device for supported joint of cage vertical well of the present invention and existing various fixed wells, carrying device for cage is compared, and has advantages of:

1. energy-conservation;

A. the equipment total amount is light, and stretching out and retracting is all under zero load, or helps to move under retracted mode in heavy duty.Movable body all adopts again and rolls and lever drive, so energy consumption is very low.

B. there is no actuating device electronic, pneumatic, that surge, the action of catching device relies on the interlock of leverage and cage false bottom dish, also namely leans on the potential energy of false bottom dish to provide.Because energy consumption is very little, even can ignore in elevator system.Linkage lever stretch out the thick stick club head by solenoid actuated, but action energy consumption once also just 10 kilograms * below 0.1m.

C. this catching device does not need to arrange cage chair, the inside and outside track cross level docking of tank during the loading and unloading vehicle, and caging car puller advance and retreat stroke all can shorten, and energy consumption also can reduce.During the personnel of up and down, the catching device of cage chair is arranged, the rocking arm that must rise and fall, not only consuming time but also consume energy.This catching device does not have cage chair, as conventional lift, stops after tank to save the energy consumption when rising and falling directly into and out of personnel.

2. save time;

A. this catching device stretches at the end and the top that promote circulation the pawl of admitting a child into a nursery school, and namely completes the operation of catching device in dynamically by the interlock of leverage and cage false bottom dish.The cage one of operation stops, and can grasp car immediately.The shared stop time of catching device itself is " 0 ".

B. this catching device adopts the shaft bottom stopping a train at a target point.Only have plastic elongation to marry again well head, elastic elongation stays out of stopping a train at a target point, does not exist catching device to exceed because stopping the tank error scope of accepting, and needs secondary to tank, even repeatedly pottle is lost time.

C. loading and unloading operation is also to have been broken away under the Winding rope state by rigid support at the false bottom dish to carry out, and before and after handling process and loading and unloading, does not need separately to add the absorption steel cable and is harmful to the shock absorber of concussion and increases the stop time.

3. simple in structure:

No matter be heavy duty or underloading, all use a cover catching device, all use combined operation, without manual operation.Program is simple, and is simple to operate, need not be in a rush, just can load and unload fast various different loads.

4. safety;

A. the safety of saying here refer to catching device can or can not with accepted the factor that cage bumps.Other catching devices are to go to operate to make it to accept cage after the cage of operation stops again, and first remove to accept after behaviour's car is completed and send out the lifting signal again.This program itself should be safe, but this catching device is to accept in dynamically, just has certain risk.Although the most situations of elevator system can be by predetermined velocity diagram operation, can not get rid of has the pulleying of generation, overruns, may not according to the accident of velocity diagram operation.Dynamically undertake very large advantage, can be the efficient wide road of paving that promotes.Can but avoid risk? indication of the present invention is exactly safely in the situation that efficient and risk and depositing, taking measures to eliminate all can thinkable risk, namely in high speed pulleying, low speed pulleying, hypervelocity, do not accept or remove and accept in all situations not according to the velocity diagram operation, reach and stop accepting same safety after tank.

B. a support false bottom dish is so elevator system weight (dead loading) can be weightless.

Fig. 4,5, the 6th, carrying device for cage rough package drawing of the present invention.

The 1st, holder cage shoe group, the every end of each cage has two groups of holder cage shoe groups, and each cage two ends have four groups of holder cage shoe groups.The 2nd, linkage lever system, the stretching out and withdrawal of the claw 701 that relies on the interlock of each bar and cage position to drive to hold in the palm cage shoe group 1.Two groups of holder cage shoe groups at each cage two ends share one group of linkage lever system, that is: one group of linkage lever system controls two groups of holder cage shoe groups.The 3rd, supporting construction, supporting construction formula be at rail level take the beam of going into the well as some short beams and the short column combination on basis, holder cage shoe group 1 namely is arranged on supporting construction, linkage lever is that 2 axle and bearing also are fixed on supporting construction.The 4th, the false bottom dish of cage, the above is equipped with track, so the load of transporting by cage hoisting all enters the false bottom dish, after claw stretches out, just can hold the false bottom dish, makes it to separate with dead chassis.The 5th, the dead chassis of cage, with column, take over a business, the head and the tail suspension gear of restricting is connected, and consists of the part of the dead loading of whole elevator system.Dead loading is not allow " weightlessness " in frictional geared winch promotes.

The structure of holder cage shoe group 1 as shown in Fig. 7,8,9,10.The 701st, claw, its root are enclosed within on axle 702, and axle 702 is contained in bearing 703, and bearing 703 is fixed on supporting construction 3.Holder cage shoe 701 anterior hinged support connecting rod 705, support link 705 lower ends are enclosed within on axle 707, and axle 707 intermediate sleeve have roller 706, and outermost is also overlapped pair of links 708, and connecting rod 708 other ends are enclosed within axle 709 two ends.Pass the axis hole on travelling car 710 tops in the middle of axle 709.The anterior hinged pair of links 711 of dolly 710, connecting rod 711 other ends are connected with the transmission levers 713 of linkage lever system, transmission levers 713 other ends are enclosed within (the following linkage lever that all belongs to is) on axle 716, and axle 716 is major axis, and cover has two transmission levers 713.Two groups of holder cage shoe groups of every each cage end of correspondence.Axle 716 is to be supported in two bearings 715, and bearing 715 is to be fixed on supporting construction 3.714 is two groups of lock pins, is used for limiting claw and lifts position and retrieving position.

Figure 11 is that linkage lever is schematic diagram, and described linkage lever is, is made of linkage lever 111, upper restoring lever 112, connecting rod 114, lever 113, transmission levers 713.Simultaneously, time restoring lever 116 and lower restoring link 115 have been comprised.Wherein, the 117th, dead chassis edge line, the 118th, false bottom plate edge line, the 119th, bottom equipment boundary line.

Linkage lever 111 and upper restoring lever 112, both combine with a fulcrum, namely use an axle, and both keep angle constant.Wherein linkage lever 111 stretches out claw, as shown in Figure 12,13, linkage lever 111 heads have expansion link head 121, are the ends that is enclosed within linkage lever shaft 122, roller is equipped with in the end of expansion link head 121, between its inner chamber and linkage lever shaft 122, stage clip 124 is housed.Stage clip 124 stretches out the expansion link head, and both sides Anti-release clamp 125 is housed on linkage lever shaft 122, prevents that expansion link head 121 from ejecting from shaft.The expansion link head is fixed with a traction steel rope of cable 128 in the middle of 121 tops, is connected with weight 129 by the pulley 127 on shaft.Rely on the power of weight, expansion link head 121 is often to retract.Weight 129 lower sides are provided with rotating shaft pressure pin 125, an end of rotating shaft pressure pin be placed in weight 129 below, the other end is provided with armature 126, electromagnet 123 is established in armature 126 belows.Only have electromagnet 123 energisings, suck back armature 126, hold up weight 129 by rotating shaft pressure pin 125, expansion link head 121 could rely on the elastic force of stage clip 124 to stretch out.Linkage lever middle part and connecting rod 114 upper ends are hinged, and an end of the lower end of connecting rod 114 and lever 113 is hinged, and lever 113 other ends are fixed on axle 716, also fix two transmission levers 713 on axle 716, and lever 113 keeps set angles constant with transmission levers 713.

Anchor shaft is established at lower restoring lever 116 middle parts, and an end and lower restoring link 115 upper ends are hinged; The lower end of lower restoring link 115 and lever 113 are hinged.

Figure 14, the 15th shows the position of pressing the linkage lever briquetting 141 of linkage lever 111 on cage false bottom dish.The bottom surface of linkage lever briquetting 141 has reached the bottom surface on dead chassis 5 over false bottom dish 4.This is because linkage lever is the cause that will be placed on below rail level.Although the bottom surface of linkage lever briquetting has reached dead chassis 5 height, linkage lever briquetting 141 is the parts structure under false bottom dish 4 is stretched, is integrant with false bottom dish 4.Linkage lever briquetting 141 is arranged on the position of broad ways on the false bottom dish, as shown in figure 15.When pressing linkage lever 111(to only have the expansion link head 121 of linkage lever 111 to stretch out below linkage lever briquetting 141, expansion link head 121 just can be positioned under the bottom surface of linkage lever briquetting 141).Upper restoring lever 112 is pressed in above linkage lever briquetting 141.

What Figure 16,17 showed is structure and the position of depressing the lower restoring lever briquetting 142 of restoring lever 116 on the false bottom dish.Lower restoring lever briquetting 142 also is in dead chassis height scope, and is slightly higher than linkage lever briquetting 141, and Width is in false bottom dish outermost.Although lower restoring lever briquetting 142 is in dead chassis height, also only belongs to the part of false bottom dish.For keeping the ventricumbent state in 142 end of lower restoring lever briquetting constant, be provided with the briquetting guide rail 161 of lower restoring lever briquetting 142 on dead chassis.Lower restoring lever briquetting 142 upper articulations have depression bar 162, and depression bar 162 is upper coarse and lower fine, on false bottom tray bottom projection, gross porosity are arranged, can be by particle size on depression bar, and briquetting guide rail 161 guide holes on dead chassis are thinner, can be by thin footpath on depression bar 162 but can not pass through particle size.Be fixed with two extension springs 163 below depression bar 162 top flange and between above false bottom tray bottom projection.Depression bar 162 top flange are equipped with guide rail 164 in the another both sides relative with extension spring is installed, the characteristics of lower restoring lever briquetting 142 are: when the false bottom dish was held up, the following pressure of lower restoring lever briquetting 142 can reach false bottom dish body by depression bar 162, extension spring 163.Held up when the false bottom dish holds in the palm cage shoe, when the false bottom dish separated a segment distance with dead chassis, lower restoring lever briquetting 142 was substantially constant with the relative height on dead chassis.A segment distance separately by depression bar descend compensated, this at present the restoring lever briquetting look like for 142 times and receive pressure, can only reach the false bottom dish by depression bar, extension spring equally.

The below is that cage arrives the shaft bottom, specifically accepts the process of cage:

General cage hoisting has 5 stage speed, i.e. 1. starting accelerating sections, 2. constant speed section, 3. braking section, 4. low speed jerking motion section, 5. ramp to stop section.

No matter be double-hook hoisting or single-hoisting, the catching device in shaft bottom is all the cage of accepting downward operation.When closing on terminal point, generally all to be in the low speed jerking motion state.But under accident conditions, also might be at full speed by terminal point, Half Speed by terminal point, slow down by terminal point, close on terminal point lower than creeper speed, these are all error staties, do not allow to accept cage.Because accept under abnormal speed, can cause either large or small damage and elevator system to cause beyond thought accident to cage and catching device.For this reason, this catching device needs a kind of speed protection: only have by running velocity figure, by closing on the predetermined location of terminal point, just can send speed signal with predetermined creeper speed, linkage lever bar head is stretched out, thereby the holder cage shoe is stretched out.Specific practice is on (or on close dead chassis of false bottom dish) on the false bottom dish, a speed marker to be installed, be equivalent on the stock of shaft bottom on the low speed jerking motion fragment position by a rate meter group, measure the cage of decline by the speed of rate meter group, only have by predetermined wait low speed by the time just can send out speed signal the bar head is stretched out, other by non-predetermined speeds such as full speed, Half Speed, acceleration, deceleration, Ultra-Low Speeds by not sending out speed signal.Even also pass through by the predetermined low speed that waits when cage rises, because be oppositely to test the speed, also can not send out speed signal.Speed signal can make electromagnet 123 attract armature 126, drives rotating shaft pressure pin 125, lifts weight 129, and expansion link head 121 is shot out.

(2) this catching device requires press tank position signal stopping a train at a target point, because cage has the false bottom dish, during stopping a train at a target point, the false bottom dish separate a segment distance with dead chassis, and the false bottom dish is held by claw outside tank again, thus all loadings alive all with cage and elevator system disengagement.Elastic elongation by the loading of living causes is absorbed in lifting process, thus impute to the well head catching device when stopping a train at a target point only have the steel cable plastic elongation.

(3) move downwards when cage or slack tank with load.And with normal predetermined speed figure operation.Arrival closes on the low speed jerking motion section of terminal point will send speed signal.Make electromagnet 123 energisings, expansion link head 121 stretches out.Linkage lever briquetting 141 bottom surface compressing linkage lever 111 revolutions on the false bottom dish, and drive transmission levers 713 revolutions by connecting rod 114, lever 113, axle 716, thus travelling car 710 is moved, claw 701 stretches out.Cage continues low speed and descends, and the undersurface of bottom disc of living contacts and held with the claw face.At this moment, lower restoring lever 116 turn to horizontality with the rotation of linkage lever 111, and the bar head of lower restoring lever 116 is attached to the bottom surface of lower restoring lever briquetting 142 on just.Cage continues to descend, and after the false bottom dish separated a segment distance with dead chassis, cage was met tank position signal location and stopped.At this moment, just in time docked with the outer trapped orbit level of tank by the track on the false bottom dish of holding.Need not carry out again any operation, can grasp the car operation immediately, also namely load and unload operation.Can send out after completing to promote on signal and carry cage.When starting, speed is started from scratch due to false bottom dish and dead chassis distance of separation very short (general 100mm is following), and speed is very low, has the steel cable elastic elongation to cushion.Extremely, flexible buffering again between the false bottom dish, so pulsation-free very when dead chassis takes up the false bottom dish.On carry in process, the top meeting of linkage lever briquetting 141 is run into restoring lever 112 and is made linkage lever 111 reversed turnings.Thereby claw 701 is regained.Keep normal retracted state.It is after dead chassis takes up the false bottom dish that linkage lever briquetting 141 is run into restoring lever 112, also carries in circulation on namely.First mention the false bottom dish, rear withdrawal holder cage shoe.

(4) car is dynamically accepted, is grasped in the lower fortune shaft bottom that more than is single decker cage.Then put forward the process of dynamic withdrawal holder cage shoe on give a signal.If multideck cage, the multilayer entrucking is also that orlop is first accepted, and is identical with individual layer tank program.Difference is to be that give a signal promotes after individual layer tank completed loading, it is also new lifting circulation beginning, and be that the give a signal low speed jerking motion descends after multi decker cage orlop completed loading, this at present restoring lever briquetting 142(see Figure 16,17) the lower restoring lever 116(of compressing that can descend sees Figure 11) revolution.By lower restoring link 115, lever 113, axle 716, make transmission levers 713 reversed turnings, even also stretched out and the claw of holding the false bottom dish is slowly regained, the false bottom dish also slowly closes up with dead chassis.instantly restoring lever 116 is forwarded to a rear linkage lever 111 by lower restoring lever briquetting 142 pressures and just is reset to normality, be horizontal, but expansion link head 121 is retracted, cage continues to descend, when upper strata false bottom dish passes through speed measuring point, if predetermined low speed jerking motion such as grade, will send out speed signal stretches out expansion link head 121, if (higher than, can not send speed signal lower than predetermined speed or non-constant speed), the linkage lever briquetting 141 of cage upper strata false bottom dish will be pressed and be turned linkage lever 111, claw is stretched out, cage continues to descend, claw is held the false bottom dish, the inside and outside track cross level docking of tank, descend again, after dead chassis separates a predetermined segment distance with the false bottom dish, shaft bottom tank position signal location is met and stopping a train at a target point in dead chassis, upper strata, can carry out immediately upper strata behaviour's car.If also have the 3rd layer after complete, descend with regard to the give a signal low speed jerking motion.If there is no the 3rd layer, just to carry on give a signal, the beginning of circulation will first slowly close up extremely, the false bottom dish, lifts the false bottom dish, then regains claw.

After if every layer of false bottom dish held up, extremely, the false bottom dish separates preset distance, the dead chassis of this layer crossed tank position signal location and do not stop, during namely with the creeper speed pulleying, lower restoring lever briquetting 142 also can be pressed and be turned lower restoring lever 116, claw is slowly regained, and the false bottom dish slowly closes up with dead chassis, and catching device can not have an accident with elevator system.

The setting of lower restoring lever except above-mentioned effect, during with the creeper speed pulleying, can make the false bottom dish reset when cage, has played the effect of overwinding safety gears.
