Description
Modified form is by existing a kind of novel lift gate mechanism to drawing the winding type lift gate mechanism to form through improvement to drawing the winding type lift gate mechanism, is called for short modified form to drawing lift gate mechanism.
Existing is the most novel a kind of in the existing lift gate mechanism to drawing lift gate mechanism.It can open many fan brakes door synchronously only with a small winch.It had obtained national patent in 1987.The patent No. 852042698.Now existing three application examples of this lift gate mechanism.Through the practice test, prove that its aufbauprinciple is correct, novel structure is light and handy, and it is flexible to open lock, easy to operate, cheap.Now its aufbauprinciple and integral arrangement are described as follows:
One, aufbauprinciple
Existing is to design according to two kinds of new lifting principles to drawing lift gate mechanism: a kind of is series connection assembly pulley principle, and another kind is two running block principles.The series connection assembly pulley is in series mutually by two or more assembly pulleys.Its laborsaving multiplying power equal the to be connected product of the laborsaving multiplying power of several assembly pulleys.The pulley at two running blocks two ends all is a movable pulley, and promptly the pulley at two ends can both move, can both lifting.It is movable pulley that existing common assembly pulley has only an end, and the other end is a fixed pulley.Fixed pulley can not move, can not lifting.So the laborsaving multiplying power of two running blocks is twices of common assembly pulley.From the above, the series connection assembly pulley is all very high with the multiplying power of two running blocks.The multiplying power of assembly pulley is higher, and then the scale of hoist engine is littler, thereby the cost of whole lift gate mechanism is also lower.This explanation, the series connection assembly pulley all is very advanced with two running blocks.
Two, integral arrangement
See accompanying drawing 4, existing to draw lift gate mechanism by common vertical assembly pulley ［ 3 ］ several, three big parts such as ［ 12 ］ one of two moving horizontal trolley groups, ［ 16 ］ one ones in common hoist engine are in series mutually.The vertical pulley block ratio is general to adopt 2.Two moving horizontal trolley group multiplying powers are general to adopt 2 * 8 to 2 * 12.Hoist engine is installed in multispan gate starting bridge ［ 7 ］ one ends.Each suspension centre of the every fan brake door of vertical assembly pulley ［ 1 ］ ［ 2 ］ is provided with one.Its movable pulley ［ 4 ］ is connected on the gate suspension centre.Its fixed pulley ［ 5 ］ is fixed on the overhead gate starting bridge of corresponding suspension centre bottom surface.The horizontal trolley group crouches at multispan gate starting bridge end face along the bridge axis is flat.The series connection method of plumbous heavy assembly pulley and horizontal trolley group is: on the end of the bridge of multispan gate starting bridge two ends, respectively establish leading block ［ 8 ］ several.With whole vertical assembly pulleys divide equally for about two groups, and lay respectively at lock chamber and flow to central axis ［ 17 ］ (abbreviation axis of symmetry) left and right sides downstream.Left and right sides vertical assembly pulley number equals left and right sides leading block number.Make each root vertical hoist cable ［ 6 ］ head end be connected on the fixed pulley axis of vertical assembly pulley separately, make the rope body twine moving fixed pulley again, turn 90 degrees from the top fixed pulley then curved, the one-tenth level to.Again about the order the two groups of vertical hoist cables respectively to the left and right two sides advance dorsad.To left and right sides end of the bridge, two groups of leading blocks about walking around respectively, and turnback is curved, become again level to.March forward mutually to axis of symmetry respectively then.Last its end is connected to two ends, the horizontal trolley group left and right sides.The series connection method of horizontal trolley group and hoist engine is: make horizontal hoist cable ［ 14 ］ head end ［ 15 ］ be fixed near the bridge floor in multispan gate starting bridge center.Make the rope body twine two ends movable pulley ［ 13 ］ again.Bend from an end movable pulley turnback then, and advance to hoist engine ［ 16 ］.Last its end is wound on the lifting drum.Arrive this, vertical assembly pulley ［ 3 ］, horizontal trolley group ［ 12 ］ just are connected into integral body with hoist engine three big parts such as ［ 16 ］, form one one complete to drawing the winding type lift gate mechanism.Start hoist engine ［ 16 ］, just changeing winding drum, the horizontal hoist cable ［ 14 ］ of reeling, then the movable pulley at horizontal trolley group two ends ［ 13 ］ constant speed moves in opposite directions.Thereby two groups of vertical hoist cables ［ 6 ］ drive the right two groups of vertical movable pulley in a left side ［ 4 ］ constant speed rising synchronously respectively about affecting.Thereupon, all also constant speed risings synchronously of gate ［ 1 ］.Otherwise, the reversing winding drum, then all the synchronous constant speed of gate descends.
For the movable pulley that makes the two running block two ends of level can constant speed move in opposite directions or dorsad, the suffered power that opens in its two ends must be equal fully.But in fact because various members are being made and the error of installing, a power is opened at two ends can not be equal fully.In order to address this problem, respectively to set up a vertical assembly pulley on two suspension centres in order center, and be referred to as to transfer the power assembly pulley.Transfer the two sides turning to the left and right respectively across of power hoist cable for two about order, and group is gone in the two groups of vertical hoist cables in a right left side respectively.Like this, utilize the elasticity of hoist cable, can adjust the suffered power that opens in horizontal trolley group two ends automatically, make it keep equal at any time.Put into practice verifiedly, this accent power method is fully success.In addition, can open whole gates for making lift gate mechanism, also can the opening section gate, vertical hoist cable ［ 6 ］ must adopt active joint with being connected of horizontal movable pulley ［ 13 ］, can connect, and also can get loose.Active joint generally adopts nut bolt ［ 10 ］.Put on and lemon when tight when nut ［ 11 ］, both promptly are connected.When nut was laid down, both can get loose.The general employing of hoist engine is electronic and manually two supporting.When non-transformer, also can only adopt manually.Adopt when electronic, magnetic switch should be set on power circuit.In the magnetic switch thermal relay should be installed.Like this, when opening the too small or gate of power design and overloaded by card, magnetic switch can be cut off the electricity supply automatically, and hoist engine can stop to open lock automatically, thereby can make overload unlikely excessive, with the protection lift gate mechanism.
Existing to drawing the lift gate mechanism novel structure light and handy, flexible operation is a kind of good lift gate mechanism freely really.But realize that in practice also there are some shortcomings in it.Now its shortcoming is described as follows:
One, existing is two to drawing the lift gate mechanism regulation to transfer the power suspension centre, and is positioned at the center of whole suspension centres.On each accent power suspension centre, set up one in vertical assembly pulley, and be referred to as to transfer the power assembly pulley.But always to fan number be odd number when gate, and when suspension centre was single suspension centre, the center suspension centre had only one, rather than two.Like this, can't arrange accent power hoist cable according to afore mentioned rules.That is to say, can not open for this gate.
Two, blocked as gate, and operating personnel are not when knowing, if adopt synchronous unlatching method to open whole gates by normal condition, then opening a power will overload, and all gates will open motionlessly, and lift gate mechanism will damage because of overload.Existing be: when when opening lock, magnetic switch being installed on power circuit with electronic to the way of drawing lift gate mechanism to address this problem.When the overload value reached the design License Value, magnetic switch can be cut off the electricity supply automatically, and hoist engine can stop to open lock automatically.When manually opening lock,, then stop to open lock at once if when feeling the elevator force rate normally to open lock being big.Though it is not these ways also have certain effect, thorough.Its reason is: because a hoist engine will open many fan brakes door, so the overload of elevator power reflected is the overload that whole gates open a power.And actually open the overload of power and concentrate on by on the card gate.Like this, blocked gate vertical assembly pulley overload value and will be surpassed the design License Value.When manually opening lock, only determine that with sensation the overload value is correct inadequately.In addition, when gate is blocked, can't be opened certainly by block gate, but non-card gate must still can open, in case the casual gush forth of flood causes the accident.Want to open non-card gate, must find out earlier by the card gate.But find out that by the card gate be not a lead-pipe cinch.Existing to drawing lift gate mechanism not propose effective solution.It is very rare that gate is blocked that yes.But its possibility exists.So this problem must be prevented.
Three, no matter open whole gates and part gate, preferably can both adopt synchronous unlatching.This is that discharge per unit width is less because unlatching synchronously can be used water seal stream evenly, and absorption basin energy dissipating load is lighter, thereby can avoid absorption basin to be damaged.Existing can be synchronous when drawing lift gate mechanism to open whole gate, but then can not be synchronous during the opening section gate.Not only can not be synchronous, and asynchronous also imperfection.Analyze its reason and have two: the first transfers the power structural configuration not good.It two is that practicable gate lock is not set.Though it is existing to drawing lift gate mechanism in patent specification, also once to mention ", gate lock should be set " for the opening section gate.But only to be a notion do not have practicality for this.Because the gate lock to the gate lock that draws lift gate mechanism and existing old-fashioned lift gate mechanism is diverse, promptly there is not the prior art can be for referencial use.Want to design this gate lock, must innovate, could realize.
Research purpose of the present utility model is that goal of the invention is: improvement is existing to make it can promptly open whole gates synchronously to drawing the winding type lift gate mechanism, and can also promptly synchronous or asynchronous opening section gate.In addition, when gate is blocked, it can be found out by the card gate automatically rapidly in the moment that just begins to open lock, so that in time stop to open lock, the protection lift gate mechanism; And in time open non-card gate, prevent the flood accident of overflowing.The method of improvement is modified form to be set to drawing the winding type lift gate mechanism.Now the technical scheme with its improvement is described as follows:
One, increase novel device:
1, novel accent power gate is set:
See accompanying drawing 1, in many fan brakes door (1), specify a fan to be accent power gate (18).When gate is always fanned number and is odd number, specify center one fan to be accent power gate.At this moment transfer the power gate to be symmetrical in axis of symmetry ［ 17 ］.When gate was always fanned number and is even number, specifying the arbitrary fan in the two fan brake doors of center was accent power gate.At this moment transfer the power gate to be partial to axis of symmetry one side, promptly asymmetric.Accent power gate suspension centre can be two suspension centres, also can be single suspension centre.On each accent power suspension centre ［ 2 ］, ［ 3 ］ two in vertical assembly pulley is set.Two vertical hoist cables ［ 6 ］ of two vertical assembly pulleys bend towards two sides, the left and right sides respectively, and about group is gone into respectively in the two groups of vertical hoist cables.Make each transfer two vertical assembly pulleys on power suspension centre to bear and open door, also can both bear accent power, and, bear different tasks respectively according to the concrete combined situation of intending throttle valve.What in addition, make accent power gate again strengthens 20% from other gate of anharmonic ratio.The weight of this increasing is called accent power weight ［ 19 ］.
From the above, accent power gate is set and has only increased an accent power weight.As for increasing the vertical assembly pulley, existing to drawing lift gate mechanism equally also will increase.Accent power weight only is 20% of deadweight, and is expensive and few.But be provided with after the accent power gate, can not only open whole gates synchronously, and in most of the cases, synchronously the opening section gate.
2, novel card lock alarm buzzer is set:
The front was said, when gate is blocked, if open whole gates synchronously by normal condition, then opened the Men Lihui overload, and lift gate mechanism might be damaged.Also have, when gate is blocked, must find out rapidly by the card gate, so that in time open non-card gate.Not so, will overflow by flood, cause the accident.It is exactly in order to address these problems that card lock alarm buzzer is set.The structure that will block the lock alarm buzzer now is described as follows:
See accompanying drawing 1 and accompanying drawing 2, ［ 9 ］ one of card lock alarm buzzers are set on each suspension centre of every fan brake door ［ 1 ］ ［ 2 ］, be installed on this suspension centre vertical assembly pulley fixed pulley ［ 5 ］ wheel shaft, and be connected with this vertical assembly pulley hoist cable ［ 6 ］ head end.Each alarm buzzer is made up of three parts such as force transferring part, alarm component and outage parts.When the building site non-transformer and only when manually opening lock, can not establish the outage parts.Force transferring part is made up of with power transmission bolt members such as ［ 25 ］ steel pipe crossbeam ［ 21 ］, steel plate bearing ［ 22 ］, bolt bearing ［ 23 ］, dynamometer spring ［ 24 ］.Vertical hoist cable ［ 6 ］ head end hangs on the steel pipe crossbeam.The steel plate bearing hangs on vertical fixed pulley ［ 5 ］ wheel shaft.The bolt bearing hangs on the gate starting bridge ［ 7 ］.Alarm component by alarm box ［ 26 ］ bell switch ［ 27,28 ］, universe circuit advance electrolytic copper piece ［ 27 ］, universe circuit electric copper output piece ［ 28 ］, advance electric universe circuit ［ 29 ］, go out electric universe circuit ［ 30 ］, electric bell ［ 31 ］ formed with dry-cell members such as ［ 32 ］.The outage parts are advanced electrolytic copper piece ［ 37 ］, divide live wire electric copper output piece ［ 38 ］, advance electric branch live wire ［ 39 ］, go out electricity branch live wire ［ 40 ］, outage dish ［ 41 ］, advance electricity branch firewire jack ［ 42 ］ and go out electricity branch firewire jack members such as ［ 43 ］ to be formed by swivel plate ［ 33 ］, spring to break ［ 34 ］, outage dish switch ［ 37,38 ］, the fiery money of branch.From the above, ［ 31 ］ one on electric bell is housed in each alarm buzzer ［ 9 ］.Its power supply adopts dry-cell ［ 32 ］.But whole shared dry-cells of electric bell.Each electric bell dress universe circuit ［ 29,30 ］.Each bar universe circuit is parallel with one another, and all passes through dry-cell.So claim that this dry-cell is a multicircuit dry-cell in parallel.Each bar universe circuit is no powers all at ordinary times.When an energising was wherein arranged, electric bell will make a sound.When hoist engine ［ 16 ］ adopts when electronic, two circuit are arranged, i.e. live wire ［ 44 ］ and ground wire ［ 45 ］ in the electrical source of power.By outage dish ［ 41 ］, make live wire pass through whole alarm buzzers.Be called branch live wire ［ 39,40 ］ by outage dish to the live wire of each alarm box ［ 26 ］.Each bar divides live wire to connect mutually.So claim this outage dish to be series connection multicircuit outage dish.Each bar divides live wire all to switch at ordinary times, and promptly power firestreak ［ 44 ］ is open to traffic at ordinary times.Open magnetic switch ［ 46 ］, hoist engine ［ 16 ］ starts immediately.When each bar divides arranged when outage in the live wire, power firestreak promptly is cut off, and hoist engine stops immediately.For the ease of operation, 3 members such as electric bell, multicircuit dry-cell in parallel and the multicircuit outage dish of connecting should be installed in the hoist engine pulpit.Now the operation logic with alarm buzzer is described as follows:
See accompanying drawing 2, when opening lock, vertical hoist cable ［ 6 ］ at first is subjected to Qi Menli.Reach steel plate bearing ［ 22 ］ and bolt bearing ［ 23 ］ by steel pipe crossbeam ［ 21 ］ then.The Men Lixian that opens that reaches the bolt bearing acts on the dynamometer spring ［ 24 ］, reaches bolt again.Spring is subjected to opening Men Lihou, can produce compressive strain.Along with the progressively growth of Qi Menli, distortion also increases gradually.Therefore can predict the size of Qi Menli according to the size of camber of spring.During camber of spring, power transmission bolt ［ 25 ］ descends gradually.Be connected the elastic force clip ［ 25 ' ］ on its top, ［ transmission of 25 " ］ is risen gradually through pulley.When certain fan brake door is blocked, when it opened a power overload value and surpasses the design License Value, the elastic force clip can break away from swivel plate ［ 33 ］.After swivel plate breaks away from the elastic force clip,, divide live wire ［ 39,40 ］ no power, that is power firestreak ［ 44 ］ is cut off because the effect of spring to break ［ 34 ］ can disengage suddenly with electric copper output piece ［ 37,38 ］ thereby make the branch live wire advance electricity suddenly to anticlockwise.After power supply was cut off, hoist engine ［ 16 ］ stopped to open lock.In addition, after anticlockwise, universe circuit advances electricity and is in contact with one another with electric copper output piece ［ 27,28 ］ swivel plate suddenly, universe circuit ［ 29,30 ］ energising, thereby electric bell makes a sound.
From the above, when gate was blocked, if open lock by normal condition, then in the moment that just begins to open lock, the electric bell that is blocked gate card lock alarm buzzer can make a sound rapidly automatically.At this moment if manually open lock, can stop to open lock at once.If the electronic lock that opens, then the outage dish can be cut off the electricity supply rapidly automatically, and hoist engine can stop to open lock rapidly automatically.Like this, the overload value of Qi Menli just can not surpass the design License Value, thereby can protect lift gate mechanism, is not damaged.In addition, make a sound the pairing gate of electric bell be exactly by the card gate.Find out by the card gate, promptly know non-card gate.Thereby can in time open non-card gate rapidly,, cause the accident in case flood overflows.Though card lock alarm buzzer part is more, their members are tiny, and do not adopt the special expensive material, so expensive and few.
3, novel gate lock is set:
During the asynchronous unlatching of gate, can only open the gate of axis of symmetry one side at one time.If it is less that at this moment the opposite side gate opens a power, must pin.Want to pin gate, must determine the position that gate need pin earlier, i.e. lock-bit, and locking ［ 20 ］ is set on lock-bit, could realize.Lock-bit has three kinds, the lock-bit of promptly leaving, lock-bit and whole Cheng Suowei etc. midway.The departure lock-bit is in order to preventing gate opening, and whole Cheng Suowei moves on behind the top or retreats in order to prevent that gate from rising to.Lock-bit moves on after the little aperture or retreats in order to prevent that gate from rising midway.Departure all only needs one with whole Cheng Suowei, but lock-bit then can have a plurality ofly midway, decides on the size of little aperture.General little opening value adopts 1/3 to 1/4 of full gate.Can not be located on the gate the gate lock that draws lift gate mechanism, and must be located on the horizontal movable pulley.When the horizontal movable pulley of an end was lockable, all gates that then are suspended on this end movable pulley all were lockable.So in fact so-called gate lock is exactly horizontal movable pulley locking, in fact so-called gate lock-bit is exactly the position that the respective horizontal movable pulley is stopped on the multispan gate starting bridge.From the above, gate lock wants anchor the multispan gate starting bridge on the one hand, also will connect horizontal movable pulley on the other hand.For making locking the multispan gate starting bridge by anchor, two of locks must be set on each lock-bit, and lay respectively at respective horizontal movable pulley upstream and downstream both sides.Lock generally adopts steel pipe.Its bottom is imbedded in multispan gate starting bridge ［ 7 ］ the longeron concrete.Bridge floor is exposed on its top.Gate lock ［ 20 ］ adopts movable, can move.Now its structure is described as follows:
See accompanying drawing 3, each locks by ［ 47 ］ one on bolt, and ［ 48 ］ two on nut and three kinds of members of ［ 49 ］ two grades of steel loop are formed.Two steel loop gardens are in the heart apart from equaling to face mutually two lock-bit spacings.During stop, a shilling respective horizontal movable pulley ［ 13 ］ rests in and gives on the fixed lock-bit.Get two of lockings then, be placed on horizontal movable pulley upstream and downstream both sides respectively.Making the steel loop of two locking one ends be enclosed within horizontal movable pulley wheel shaft two ends respectively again appears on ［ 51 ］; The steel loop of the other end is enclosed within last lock-bit or back one lock-bit two locks respectively and appears on ［ 50 ］.Tightening nuts makes the steel loop tightly horizontal movable pulley wheel shaft of pulling and the lock at locking two ends.Like this, horizontal movable pulley promptly is lockable, and the gate of homonymy also is lockable.When pinning a lighter side gate, should prevent that the horizontal movable pulley of homonymy from advancing.Pin when weighing a side gate, should prevent that the horizontal movable pulley of homonymy from retreating.When preventing to advance, steel loop ［ 49 ］ should be enclosed within to be intended behind the lock lock-bit on the lock.When preventing to retreat, should be enclosed within on the previous lock.Like this, can make and lock tension all the time.
From the above, locking is a tensional element, can give full play to the intensity of manufactured materials, thereby member is little, and is in light weight.Locking can be adjusted self length by nut ［ 48 ］.Thereby horizontal movable pulley not necessarily needs granting the lock position when stopping.Thereby can avoid adjusting repeatedly, to shorten the stop time.Locking can be moved, and can reuse on axis of symmetry ［ 17 ］ one all lock-bits of side.So requirement seldom, whole lift gate mechanism only needs 4.Lock required lock power and only be used for the suffered difference that opens a power in equilibrium level assembly pulley two ends.So its value is little.1.2 times of general employing one fan brake door vertical hoist cable pulling force get final product.Be provided with after the locking, adopt the asynchronous unlatching method of many wheels to create conditions when can be the opening section gate, its principle is detailed more later on.From the above, this gate lock not only structure is light and handy, and is expensive few, and function is superior.
Two, the lock method is opened in improvement:
The utility model is owing to set up three kinds of novel features such as accent power gate, card lock alarm buzzer and practicable gate lock, and it opens the lock method than having now drawing lift gate mechanism that many improvement are arranged.Now the lock method that opens with its improvement is described as follows:
The utility model adopts synchronous unlatching method to open whole gates when normal condition, but then also can adopt synchronous unlatching method or asynchronous unlatching method opening section gate when improper situation.No matter open whole gates and part gate, the lock principle that opens that it is total has two:
Article 2,, when adopting asynchronous unlatching method, need not carry out accent power, transfer the power gate to be blocked, also can non-ly block.But the plan that is positioned at the axis of symmetry both sides opens gate fan number preferably to be equated.If etc., do not differ a fan at the most.Not so, the suffered lock power of gate lock can increase greatly.
According to the above-mentioned total principle of lock that opens, can open whole gates or part gate.Now the open method with them is respectively described below:
1, open the method for whole gates:
A, when gate is always fanned number and is odd number:
At this moment transfer the non-card of power gate, and be symmetrical in axis of symmetry.The plan that is positioned at accent power gate both sides opens gate fan number and equates.According to opening the 1st of the total principle of lock, at this moment can open whole gates synchronously.Start hoist engine, all gate rises immediately synchronously.Its concrete principle is: at this moment to open a power equal substantially in both sides, but not exclusively equate.When opening lock, a lighter side gate necessarily rises in advance.When a lighter side gate rose, the accent power hoist cable that bends towards this side can be taken away accent power weight, thereby the Men Li that opens of this side is increased gradually, weighed a side and then reduced gradually.As a result, both sides are opened Men Li and are moved closer to.When treating that both sides are opened a power and equated, then two side gates are opened synchronously.
B, when gate is always fanned number and is even number:
At this moment transfer the non-card of power gate, and be partial to axis of symmetry one side.The plan that is positioned at accent power gate both sides opens gate fan number and does not wait, but only differs a fan.According to opening the 1st of the total principle of lock, at this moment can open whole gates synchronously.Its concrete principle is: owing to transfer the power gate to be partial to axis of symmetry one side, so accent power weight also is partial to axis of symmetry one side, thereby both sides are opened Men Li and are not waited.Accent power gate homonymy open the door greater than offside, its difference equals to transfer power weight.Though both sides are opened Men Li and differed more, transfer the power gate still to have the ability to carry out accent power.When opening lock, side gate is necessarily risen in advance.When side gate was risen, the accent power hoist cable that bends towards offside can be taken away accent power weight.Increase gradually thereby make offside open Men Li, homonymy then reduces gradually.As a result, both sides are opened a power and are equated, thereby two side gates are opened synchronously.
From the above, transfer power equipment not necessarily to need to be symmetrical in axis of symmetry, transfer the power suspension centre also not necessarily to need two.And existing to drawing the lift gate mechanism regulation to transfer the power suspension centre to be necessary for two, and be symmetrical in axis of symmetry.Thereby always to fan number be odd number when gate, when suspension centre is single suspension centre, can not open whole gates.
2, the method for open portion gate:
The situation that the part gate is arranged is very complicated.It both can be a fan, also can be many fans.Both a side can be positioned at, also both sides can be positioned at.When being positioned at both sides, both can be symmetrical, also can be asymmetric.Two side gates fan number can equate, also can not wait.Also have, the tested gate in the time of both can being the gate maintenance also can be the non-card gate of gate when being blocked.Because arranging situation difference, open method are also different.Want to illustrate one by one the open method of all situations, by length is not allowed.So can only illustrate it.Now be example to open non-card gate, the method for opening section gate be described as follows:
Want to open non-card gate, must find out earlier by the card gate.Find out by the card gate and can utilize card lock alarm buzzer.Just beginning to open the moment of lock, making a sound, then having gate to be blocked certainly if hear card lock alarm buzzer.At this moment if the electronic lock that opens, then the outage dish can be cut off the electricity supply automatically, and hoist engine can stop to open lock automatically.If manually open lock, then crank should stop to shake at once, to stop to open lock.After stopping to open lock, with whole closing gates on earth, make its reinstatement.Find out that again what fan brake door electric bell makes a sound, electric bell make a sound that fan brake door be exactly by the card gate.After gate finds out by card, the connecting bolt of its vertical hoist cable end is got loose, can open non-card gate.Gate is thousand years difficult fitting by card.Generally has only a fan at one time.So non-card gate fan number equals always to fan number and subtracts one.Now the open method with non-card gate is described as follows:
A, always to fan number when gate be odd number, and the power of accent gate is when being blocked:
At this moment non-card gate fan number is an even number, transfers the power gate to be blocked, and the non-card gate fan number that is positioned at the axis of symmetry both sides equates.According to opening the 2nd of the total principle of lock, at this moment can only the whole non-card gates of asynchronous unlatching.Its concrete principle is: at this moment to open a power equal substantially in both sides, but can not be equal fully.When opening lock, a lighter side gate necessarily rises in advance.Because the power of accent hoist cable gets loose, and can not transfer power, so a lighter side gate rises always.Treat that it rises to the top, weigh a side gate and do not start yet.This open method is called half and takes turns asynchronous unlatching method.The utility model is provided with practicable gate lock.After a lighter side gate is opened to the top, it can be pinned.After a lighter side gate is lockable, weighs a side gate and just can open.Treat that it is opened to the top, then two side gates all are unlocked.This open method is called the asynchronous unlatching method of taking turns.Half wheel and one is taken turns asynchronous unlatching method all a shortcoming, exactly: when the lighter side discharge per unit width of gate reaches maximum value, weigh a side discharge per unit width and equal zero.Like this, go out water seal stream form with severe exacerbation, downstream absorption basin and river course will cause damage.So these two kinds of methods are all inadvisable, must further be improved.The method of improvement is to adopt many wheels to open.Its method is: after a lighter side gate is opened a little aperture, be about to its pinning.Order weighs side gate unlatching then.After treating two little apertures of its unlatching, also with its pinning.Make a lighter side gate secondary opening again.After treating two little apertures of its unlatching, secondary pins.Order weighs a side gate secondary opening again.After treating two little apertures of its unlatching, secondary pins.So repeat, till two side gates all are opened to the top.This open method is called the asynchronous unlatching method of many wheels.When adopting the asynchronous unlatching method of many wheels,, be more or less the same though the both sides discharge per unit width does not wait yet.So go out the unlikely severe exacerbation of water seal stream form, the unlikely damage in downstream absorption basin and river course.
B, always to fan number when gate be odd number, and during the non-card of the power of accent gate:
At this moment non-card gate fan number is an even number, transfers the non-card of power gate, and the non-card gate fan number that is positioned at accent power gate both sides does not wait, but only differs a fan.According to opening the 1st of the total principle of lock, at this moment can open whole non-card gates synchronously.Its concrete principle and above-mentioned 1b money are identical, repeat no more.
C, always to fan number when gate be even number, and the power of accent gate is when being blocked:
At this moment non-card gate fan number is an odd number, transfers the power gate to be blocked, and the non-card gate fan number that is positioned at the axis of symmetry both sides does not wait, but only differs a fan.According to opening the 2nd of the total principle of lock, at this moment can only the whole non-card gates of asynchronous unlatching.Its concrete principle and above-mentioned 2a money are identical, repeat no more.Its open method adopts the asynchronous unlatching method of many wheels.
D, always to fan number when gate be even number, and transfer the non-card of power gate, when being blocked gate and being positioned at accent power gate homonymy:
At this moment non-card gate fan number is an odd number, transfers the non-card of power gate, and the non-card gate fan number that is positioned at the axis of symmetry both sides does not wait, but only differs a fan.According to opening the 2nd of the total principle of lock, at this moment can only the whole non-card gates of asynchronous unlatching.Its concrete principle and above-mentioned 2a money are identical, repeat no more.Its open method adopts the asynchronous unlatching method of many wheels.
At this moment transfer the non-card of power gate, can transfer power, but can not open synchronously.Differ two fans because be positioned at the non-card gate fan number of accent power gate both sides, and open the 1st of the total principle of lock and be not inconsistent.Its reason is that horizontal trolley group two ends are opened Men Li and had big difference, and has surpassed the accent power ability of transferring the power gate.
E, always to fan number when gate be even number, and transfer the non-card of power gate, when being blocked gate and being positioned at accent power gate offside:
At this moment non-card gate fan number is an odd number, transfers the non-card of power gate, and the non-card gate fan number that is positioned at accent power gate both sides equates.According to opening the 1st of the total principle of lock, at this moment can open whole non-card gates synchronously.Its concrete principle and above-mentioned 1a money are identical, repeat no more.
F, always to fan number when gate be 2 whens fan:
At this moment do not have view power gate and blocked and non-card, non-card gate has only a fan.If the power of accent gate is blocked, the accent power that then gets loose gate bends towards the accent power hoist cable of offside, can open the non-card gate of offside.If transfer the non-card of power gate, the offside that then gets loose is blocked gate vertical hoist cable, can open accent power gate.
From the above, when gate was always fanned number and is odd number, as long as the non-card of accent power gate, other any fan brake door was blocked, and can both open whole non-card gates synchronously.When gate is always fanned number and is even number,, can both open whole non-card gates synchronously as long as the non-card of accent power gate is positioned at any fan brake door of accent power gate offside and is blocked.Existing to drawing lift gate mechanism owing to not establishing accent power gate and the power of accent weight, can not open whole non-card gates synchronously, and can only asynchronously open.During asynchronous unlatching,, can only adopt half to take turns asynchronous unlatching method owing to there is not practicable gate lock.Partly take turns asynchronous unlatching method and can use water seal stream form severe exacerbation, thereby cause downstream absorption basin and river course to be damaged.
Advantage of the present utility model:
One, no matter gate is always fanned number is odd number and even number, and also no matter the gate suspension centre is two suspension centres and single suspension centre, can both open whole gates synchronously.And existing always to fan number be odd number to drawing lift gate mechanism to run into gate, when suspension centre is single suspension centre, then can not open whole gates synchronously.
Two, owing to be provided with novel accent power gate and practicable novel gate lock, thereby opening section gate synchronously in most of the cases.Water seal stream form thereby improved, and quickened to open lock speed.Though under a few cases, still must adopt asynchronous unlatching, owing to imagined the asynchronous unlatching method of novel many wheels, thereby go out the unlikely severe exacerbation of water seal stream form.Existing to drawing lift gate mechanism owing to do not have novel accent power gate, practicable novel gate lock and the asynchronous unlatching method of novel many wheels, not only thereby opening section gate synchronously, and asynchronous opening section gate is also had any problem.It can only adopt half to take turns the lighter side gate of asynchronous unlatching method unlatching.Partly take turns asynchronous unlatching method and can use water seal stream form severe exacerbation, thereby cause downstream absorption basin and river course to be damaged.
Three, owing to be provided with novel card lock alarm buzzer, when gate is blocked, can find out rapidly by the card gate in the moment that just begins to open lock, thereby can in time stop to open lock rapidly, avoid lift gate mechanism to damage because of overloaing.Also have, found out, promptly know non-card gate by the card gate.Thereby can in time open non-card gate rapidly, avoid the flood accident of overflowing.Existing to drawing lift gate mechanism not block the lock alarm buzzer, state and do not have above-mentioned functions.
Four, not only function is superior for above-mentioned three kinds of novel features, and structure is light and handy, and cheap.For example: transfer the power gate only to increase by 20% deadweight.Though card lock alarm buzzer part is more, their members are tiny, also do not adopt the special expensive material.Gate lock is a tensional element, and consumptive material is few, and reusable, and quantity seldom.
