Description
Technical field
The utility model relates to the mechanically moving field of each steel plant and bargh, more particularly, relates to a kind of protective device of mechanically moving volume payout.
Background technology
In each steel plant and bargh, use more mechanically moving to have: mix on mixing ore deposit dummy car, the sintering groove on ore dummy car, the sintering groove on sintering deposit dummy car, the blast furnace groove on machine, the blast furnace groove raw material dummy car, raw material blending ore deposit groove loading and unloading material car or the like are got in harbour ship unloaders, terminal ship machine, stacker, reclaimer, stacker-reclaimer, mixing ore deposit stacker, mixing ore deposit.These mechanically movings all are the modes by cable drum, utilize reel volume, put the power supply synchronization that reaches mechanically moving and signal transmission.
At present, at home and abroad in the industrial and mining enterprises, used cable and optical cables such as the power supply of mechanically moving, control loop, communication are generally all carried out connection by two kinds of modes, a kind of is that the short equipment of displacement adopts track, coaster, anchor clamps, cable by the mechanically moving band and moves together along track by coaster cable is built on stilts; Another kind is a displacement equipment far away, or the place that can not adopt overhead track, often adopt the mode of cable drum, cable winding on reel, along with the traveling of mechanically moving lengthens cable or takes up the traveling position synchronous of the length of cable and mechanically moving.And in the second way, often all cables, optical cables such as high pressure, power, control, communication are synthesized in a cable, therefore this composite cable costs an arm and a leg, to suffer heavy losses in case damage, the indirect loss that its influence is produced is unable to estimate especially, prevents that described composite cable is damaged so will take effective measures.
In present production practices, mainly use two kinds of mechanically movings, first kind is the Japanese equipment from Japanese import, second kind is the equipment of introducing from VAI.They have a common characteristic is to be reduction cable cost and reel expense, and composite cable is drawn from the ground halfway junction box of whole displacement, and cable one end is underground at mid point by earth anchorage, can save half cable like this, reduces equipment cost.When mid point was passed through in therefore mobile machine traveling, the take-up direction of cable drum need commutate.
The cable drum of first kind of Japanese mechanically moving is driven by transmission device and torque motor, and torque motor is equipped with braking brake.For cable can fitly be taken up on reel all the time, turning to of torque motor is direction rotation towards the rolling-in cable forever.When mobile machine need shorten toward mid point direction traveling cable, the running of torque motor high voltage was taken up cable to obtain bigger driving torque.When cable need lengthen, the running of torque motor low-voltage, at this moment mechanically moving in tow cable against the motor direction of rotation, pressure makes the reel cable that lengthens that turns round in the opposite direction, this moment, the task of torque motor was to make cable drum that certain take-up force be arranged, be unlikely to make cable to cross pine or degree of tightness differs, so the operating voltage (moment) of cable drum its torque motor when batching commutation needs conversion.For reaching this purpose, diverter switch has been installed additional by rail side in Japan manufacturer on mobile motor spindle frame, and load onto montant at the ground correspondence position, mobile machine during through the centre position diverter switch handle bump montant, the switch commutation makes torque motor change operating voltage.But because the field condition complexity, the relative position of montant and diverter switch is had relatively high expectations (adjacent position also has limit switch etc.), has deviation just can not correctly collide slightly; In addition from actual operating position, diverter switch is lower apart from ground, on-the-spot because of being open-air, ground is soil, weedy, wild vetch often being taken place in the traveling catch on the diverter switch handle, cause to sever the switch knob phenomenon in diverter switch misoperation or the traveling, makes torque motor can not get correct operating voltage and cause the fault effects ordinary production.
The cable drum of second kind of mechanically moving is driven by transmission device and magnetic force catcher.For prevent mobile machine when the mid point owing to install diverter switch and montant initiating failure additional, the mobile machine that VAI is made is without diverter switch.The magnetic force catcher connects drive by the motor of the same direction of rotation of same rotating speed, when so cable is changed into relaxation state by the rolling-in state when occurring having served as mid point, the main magnet of its magnetic force catcher and the relative magnetic field slippage between the driven iron plate raise, eddy current rolls up in the iron plate, make the caloric value fragile magnetic force catcher that increases severely, can see after damaging the magnetic force catcher disintegration under changing: bearing damages owing to the too high lubricating oil of temperature is dry, the bolt of fixing driven iron plate is loosening because of expanded by heating, even iron plate and connecting axle all Yin Gaowen color is changed, all to be that eddy current is excessive in the driven iron plate cause these reasons.In addition, this structure causes that also cable its reel power of batching when lengthening increases (because of the increase of eddy current from the power iron plate of magnetic force catcher) on the contrary, makes the overtension of composite cable influence useful life.If can when crossing mid point, not install diverter switch and montant in addition additional and the motor speed that drags the magnetic force catcher is changed, then can significantly reduce the generation of magnetic force catcher fault and the replacement cycle of prolongation composite cable.
More than in two kinds of equipment; in order to prevent to break cable; installed overtension switch 51,52,53 especially additional; but installation site and movement structure are unreasonable; working condition is not as people's will; can not guarantee reliably that overtension switch 51,52,53 regular events protect cable, and this structure is not suitable for being installed on the equipment resemble the dummy car, as shown in Figure 1.This structure is if cable is wrapped on the framework of this device, and overtension sense switch 51,52,53 can't move, and along with tightening up of cable, can be easy to cause cable to break, as shown in Figure 2.
Heap, reclaimer that Japan makes because of the transmission device that drives cable drum is to be made of torque motor and braking brake, so occur the band-type brake locking unavoidably or skid malfunctioningly, also might occurs stuck and skid during the transmission device fault.First kind of situation is when band-type brake locking or transmission device are stuck, if mobile machine direction of travel requires the cable rolling-in, the consequence that then causes is that coil of cable does not get up to drag and can send the overtension signal on the ground after being caught on by foreign matter and stop traveling, or cable just be moved machine after rolling bad.If yet resemble reclaimer when gathering same kind material, often just before and after the small distance of same kind material position, move repeatedly, can not make the overtension switch motion, at this moment cable is just increased greatly by the possibility that the reclaimer travelling wheel damages by pressure, such thing once repeatedly took place in the past, and other mechanically moving of certain similar mobile device also this situation might occur.The another kind of situation that may occur is to skid or transmission device when skidding when band-type brake is malfunctioning, at this moment the cable on reel will slide voluntarily because of deadweight, stop traveling if not artificial discovery in time, then cause a large amount of cables to pile up in orbit, the overtension switch does not have effect, as long as travelling wheel is pressed onto, situation is well imagined.
Heap, reclaimer that VAI is made, though without torque motor and braking brake, magnetic force catcher when not working (when motor is static) is that the ratchet by ratchet withstands on and prevents on the motor housing that magnetic force catcher master end from rotating, the driven iron plate of its slave end (drive cable drum part) is held by unsettled under the powerful magnetic field force effect of main field, and its suction size satisfies by the gap between adjusting and the main magnet that cable can not glide because of deadweight when static.Though this structure has remedied the trouble of using braking brake to bring, but, ratchet is in the high-speed friction state with ratchet when rotated all the time, the corner angle of its ratchet are worn easily and produce and skid, the spring that supports ratchet simultaneously also can fracture because of tired, and these reasons unavoidably can make the reel breaks generation skid out of control.
In sum, above-mentioned mechanically moving equipment has caused the fail safe of cable to reduce all less than the rationally reliable cable protecting device of configuration like this, damages easily.

Described underframe 1 one sides also are equipped with low-tension switch 13, low-tension switch 13 is connected with described track 2, low-tension switch 13 is fixed on the underframe 1, the roller of its turning handle is just pushed down by the channel-section steel of track 2, when the channel-section steel of track 2 is met external force sinking (as cable landing out of control), the action of low-tension switch 13 contacts.
With reference to figure 5, described limit on the left pin 5 is fixed with left buffer spring 6, described limit on the right-right-hand limit pin 7 is fixed with right buffer spring 8, described left and right buffer spring 6,8 is a high strength helical formula spring, its inside has adjusting screw, its locking nut 61 can be used to regulate, and adjusting screw is the shift position of sliding machine 30 when being used for to the adjustment of overtension size and restriction operate as normal.
With reference to figure 6, described sliding machine 30 is stuck in the channel-section steel by wheel 9 and rolls, and the gap is as far as possible little; The frame of sliding machine 30 is made by channel-section steel or angle steel, can make assembled, is convenient to installation and removal.Welding is used to install the earrings 32 of beaming roller on four angles of described frame, front axletree 33, rear axletree 34, left beaming roller 35, right beaming roller 36 are installed on each earrings by diverse location respectively, described four beaming rollers constitute rectangle frame, described cable passes in described rectangle frame, the effect of described beaming roller is the friction that reduces cable, because cable is less in the bending of beaming roller place, contact area is few, so that the beaming roller diameter does not need is too big.
Introducing the following course of work below in conjunction with accompanying drawing is the used of each switch:
With reference to figure 7; protective device 100 integral installations described in the utility model are below cable drum 41; the track 2 of the end face of reel and sliding machine 30 at grade, cable 42 terminations are free draws in the middle of four rectangles that beaming roller surrounded downwards and from the sliding machine 30.
1, the effect of cable reversing switch
It is constant being installed in the cable drum 41 on the mechanically moving and the particular location of described protective device 100.When mobile cart 43 is positioned at cable 42 center fixed point right sides, because of making the sliding machine 30 of traveling in the channel-section steel of track 2, moves the pulling force of cable 42 to the left side, until being blocked by left buffer spring 6, while and sliding machine 30 synchronization-moving travel switch pressing plates 12 are pushed down left cable reversing switch 15, left side cable reversing switch 15 electrical contacts action is sent signal to control system, represent that mobile cart 43 is right-hand at cable center fixed point, control system output command adapted thereto, the motor that drives cable drum 41 is aligned voltage according to direction of travel, puts moment to satisfy normal volume.As long as mobile cart 43 is right-hand at cable 42 center fixed points, the travel switch pressing plate 12 of sliding machine 30 is pushed down left cable reversing switch 15 always so, and switch contact is exported mobile cart 43 all the time at right-hand signal of cable 42 center fixed points.
In like manner, when mobile cart 43 from the right-hand traveling left of cable 42 center fixed points, when cable 42 is through mid point on cable drum 41, then cable 42 drive sliding machines 30 move in the channel-section steel of track 2, until being blocked by right buffer spring 8, the travel switch pressing plate 12 that links to each other with sliding machine 30 is pushed down right cable reversing switch 16, represents that mobile cart 43 crossed mid point at cable 42 center fixed point lefts.The action of right cable reversing switch 16 electrical contacts is sent the signal of mobile cart 43 at cable center fixed point left to control system, and control system determines corresponding volume to put moment according to direction of travel again.
So, relative position by mobile cart 43 and cable 42 center fixed points, the tension force of cable 42 can control easily sliding machine 30 on the channel-section steel of track 2 the position and make the action of corresponding reversing switch contact, reliably guaranteed to drive the correct operating voltage of cable drum 41 torque motors or drag the correct rotating speed that magnetic force is taken over motor, solved the corresponding techniques problem.
It should be noted that, if be uneven after ground rail 44 distortion, mechanically moving traveling brake braking force square is big inadequately, so just such a case might appear: promptly when mobile cart 43 when the high lower of track stops traveling, though the drive motors of cable drum 41 is after cart running motor dead electricity, the certain hour of delaying time again quits work, and rolls up payout 42 in theory and can not loosen (being that reversing switch electrical contact when mobile cart stops traveling can not disconnecting).But, when cable drum 41 has quit work,, cause that the reversing switch electrical contact disconnects if mobile cart 43 because of the track height slides again, just might make volume payout 42 loosen.As this situation appears; the method that solves can be with reference to Figure 12; power supply is added on relay coil c1, the c2 after often opening (or normally closed) contact and right cable reversing switch normally closed (or often opening) contact serial connection by left cable reversing switch; when mobile cart 43 once walking about; push down relay normally open contact self-locking behind the reversing switch; even shutting down the back, at this moment mobile cart 43 cable 42 is loosened owing to sliding; cause that reversing switch contact disconnects; but, just can guarantee cart position signalling keep intact constant (at the left of mid point or right-hand) as long as another reversing switch does not have action.In addition, by regulating the adjusting screw(rod) of buffer spring, just can guarantee reliably that another reversing switch is failure to actuate (the compressing power of 42 pairs of dollies of cable is little under this situation) in these cases, cable 42 when produce stopping loosens and the problem that causes has also obtained solution so track is uneven.
2, the effect of cable overtension switch
With reference to figure 8, (transmission device machinery is stuck when certain reason causes cable drum 41 not change, the torque motor band-type brake is not opened, magnetic force catcher fault etc.), so, if mobile cart 43 continues the traveling of turning right, because cable 42 can not lengthen, cable 42 tension force will strengthen, force sliding machine 30 in track 2, further to be moved to the left and compress left buffer spring 6 (elastic force is adjustable), travel switch pressing plate 12 advances to the handle of pushing down left cable overtension switch 14, the electrical contact action of left side cable overtension switch 14, cut off running motor control power supply and stop mobile cart 43 travelings, and to control system handling cable overtension signal, control system is sent various command adapted theretos immediately, stops relevant operation.Both protect cable 42 unlikely breaking, can prevent the generation of other fault again.
In like manner, mobile cart 43 is when the left side of cable center fixed point, and right cable overtension switch 17 moves, and situation is the same the same.
3, low-tension on-off action
With reference to figure 9, under the situation of cable 42 in landing out of control, because sliding machine 30 spaces are little, so part cable 42 is deposited in earlier on the channel-section steel of track 2 of sliding machine 30, track 2 is sunk, push down low-tension switch 13 and make its electrical contact action, stop the cart traveling and send the low-tension signal to control system, control system is sent command adapted thereto and is stopped relevant operation, prevents that cable 42 from damaging by pressure and other fault takes place.
The utility model also can be used on the total travel length cables reel 41 in addition, with reference to Figure 10, so-called total travel length, be meant that cable 42 fixing points are not at the mid point of the distance travelled total length of mechanically moving, but before mechanically moving is walked beginning-of-line, mobile cart 43 cover total length apart from the time cable drum 41 do not need the commutation.When if mobile cart 43 is worked on cable 42 fixing point right sides, because cable drum 41 does not need commutation, so left in this case cable reversing switch 15 and right cable overtension switch 17 can cancel need not, keep left cable overtension switch 14 and right cable reversing switch 16 and low-tension switch 13.When cable drum 41 transmission device fault or the locking of torque motor band-type brake for a certain reason, when mobile cart 43 loosens the direction traveling toward cable, because of cable 42 can not lengthen, left side cable overtension switch 14 action carts stop traveling during overtension, protection cable 42 unlikely breaking; Low-tension switch 13 prevents when transmission device or braking brake is malfunctioning when skidding, and plays protection when (problem three) that speaking of above appears in cable 42 landings and uses.
The utility model can also solve the fault that takes place when cable 42 is caught on by foreign matter, and with reference to Figure 11, when mobile cart 43 retreats (the cart traveling is shown in the direction of arrow among Figure 11), cart moves toward cable 42 fixing points, and this moment, cable 42 need take up.Under the normal condition because the effect of cable 42 tension force, sliding machine should be in the channel-section steel of track 2 leftward position.But, when the utility model not being installed, if cable 42 is caught on by foreign matter on ground or truss, so along with the traveling of cart, not only cable 42 can not take up, more and more lengthen on the contrary, break until having put.After if the utility model has been installed, when mobile cart 43 catches on when continuing traveling forward from cable 42, the tension force of cable 42 will force sliding machine 30 to move right in the channel-section steel of track 2 and push down right cable reversing switch 16, cart running motor control power supply is cut off in the electrical contact action of at this moment right cable reversing switch 16, stop mobile cart 43 travelings, and send cable 42 to control system and caught on signal by foreign matter, need on-the-spot artificial treatment this moment.Adopt right cable reversing switch 16 to send the reason that cable catches on signal at this to be: as protecting with right cable overtension switch 17, then cable 42 suffered pulling force will be bigger, and will be unfavorable to cable 42.And adopt right cable reversing switch 16 to signal, then as long as the tension force of cable 42 can reach and sliding machine is moved in the track channel-section steel and make the switch contact action, cable stretch is much smaller comparatively speaking, not only can play effect same but also can alleviate cable fault, prolongs cable life.
In like manner; if because reasons such as fabricating yard and positional structure restriction; mobile cart 43 is in the work of cable 42 fixing points left side; all protection philosophies are all the same so; but the switch of selecting for use will be done suitable change; select right cable overtension switch 17 and left cable reversing switch 15 and low-tension switch 13 this moment for use, just can play the integrated protection to volume payout 42.
When mechanically moving adopted saucerspring as cable drum 41 actuating forces, the usage of protective device described in the utility model and function were just the same with usage and function on the total travel length cables reel 41.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of above embodiment.
