Fig. 9 is illustrated in the example of additonal pressure detection means in the oil hydraulic circuit shown in Figure 8, (a) is the oil hydraulic circuit figure of additonal pressure sensor as the pressure detecting means, (b) is the oil hydraulic circuit figure of additonal pressure switch as the pressure detecting means.Example shown in Fig. 9 (a) and (b) is to change and detect the example that is equipped with overweight vehicle M on the pallet 9 (Fig. 4) by offering the pressure that boosts with the compressed oil of oil hydraulic cylinder 26 (Fig. 8).Also have, in these figure, the part identical with structure shown in Figure 8 is marked with identical symbol and omits its detailed description.
Shown in Fig. 9 (a), pressure sensor 73 is arranged between the electromagnetic switching valve 60 and pipe arrangement 59 of rotating frame with the furcation 77 in loop 57.Formation utilizes this pressure sensor 73 to detect the pressure of the compressed oil in the pipe arrangement 59 that offers plunger case 26 (Fig. 8), and detected pressure signal outputs to the structure of the control device (diagram is omitted) of parking apparatus 1 by distribution 74.The pressure signal of input control device can judge whether to surpass the setting value of the weight of storing that writes down in advance in control device.This judgement will be recorded in control device as setting value in advance in the weight that this parking apparatus 1 can be stored, and compare judgement with this setting value.And, surpassing under the situation of this setting value, be judged as " weight surpasses and mustn't put in storage ", do not allow to carry out the driving of parking apparatus 1 thereafter.Under the situation of the pressure that detects the compressed oil that plunger case 26 is provided like this with pressure sensor 73, can correctly detect the pressure variation by enough pressure sensors 73, therefore can correctly detect overweight situation.
Shown in Fig. 9 (b), pressure switch 75 also is arranged between the electromagnetic switching valve 60 and pipe arrangement 59 of rotating frame with the furcation 77 in loop 57.The pressure that this pressure switch 75 is formed on the compressed oil that offers plunger case 26 (Fig. 8) surpasses under the situation of the setting value be pre-set in pressure switch 75 and switches, and its switching signal is imported into the structure of control device (diagram is omitted) by distribution 74.When signal that control device input pressure switch 75 switches, be judged as " weight surpasses and mustn't put in storage ", do not move the driving of the parking apparatus 1 that carries out thereafter.Like this, under the situation of the pressure that detects the compressed oil that offers plunger case 26 with pressure switch 75, because of the operator carries out mechanical adjustment to the setting pressure of pressure switch 75, so higher if desired pressure detecting precision is preferably used above-mentioned pressure sensor 73.
As mentioned above, in the example shown in Fig. 9 (a) and (b), be provided with detect offer shown in the pressure detecting means of pressure of compressed oil of plunger case 26, be equipped on the weight of the vehicle M (Fig. 4) on the pallet 9 (Fig. 4) in case become big, the pressure that utilization offers the compressed oil of plunger case 26 (Fig. 8) becomes big situation, detect the pressure of the compressed oil that offers plunger case 26 with above-mentioned pressure detecting means, can prevent the situation of storing vehicle rapidly with the weight that can not carry according to this detected value.Pressure sensor 73 in this example and pressure switch 75 are examples of pressure detecting means, also can be other structures.
Also have, surpass in the weight that detects vehicle M like this under the situation of the weight that can store, also can send parking apparatus 1 and not allow the control signal that drives, stop the storage of vehicle, for example putting the guided display upward warnings of demonstration " vehicle is overweight " such as (diagram are omitted) in storage, make the operator understand this situation simultaneously.
In the oil hydraulic circuit shown in above-mentioned Fig. 8,9, provide the compressed oil of each plunger case 26 to 4 pipe arrangements 59 that set side by side by the electromagnetic switching valve 60 (lift valve) of furcation 77 from lift valve portion 76.But the load distribution of the vehicle of lift-launch is of all kinds, and is inevitable, on the pallet of supporting by rotating frame 25 with 4 plunger cases 26 9 the load inequality can take place.For example in general automobile, the load of duty factor vehicle rear of front part of vehicle of carrying engine usually is big, and therefore because the load distribution of such vehicle, the load distribution inequality on pallet 9 also is subjected to the effect of uneven load on the plunger case 26.And sometimes cause vehicle boarded generation situation of difficult because of the uneven size of load.
For this reason, also considered the structure (being rotating frame 25 in this example) of supporting tray 9 is combined with the piston rod upper mechanical of 4 plunger cases 26,4 a kind of synchronization means of plunger case 26 usefulness link the means of supporting.But, even like this with the upper mechanical combination of plunger case 26, owing in above-mentioned oil hydraulic circuit shown in Figure 8, plunger case 26 is connected in parallel, there is big laod unbalance to do the time spent, offer the compressed oil of each plunger case 26, the oil ratio of plunger case (the being vehicle rear in the above description) side that the load that inflow is acted on is little is more, and sometimes pallet 9 is not easy to keep level.
Therefore, in this case, as long as form as shown in figure 10, the oil hydraulic circuit that the schematic diagram of other examples of the oil hydraulic circuit of presentation graphs 8 is such to make oil pressure synchronous a plurality of between boosting with oil hydraulic cylinder 26, gets final product pallet 9 levels of being maintained at.In Figure 10, the formation identical with above-mentioned oil hydraulic circuit shown in Figure 8 is marked with identical symbol and omits its detailed description.
As shown in figure 10, in this oil hydraulic circuit, replace above-mentioned rotating frame shown in Figure 8 with the furcation 77 in the loop 57, be provided with and have shunting in conjunction with the oil pressure synchronization loop portion 80 of valve 78 with electromagnetic switching valve (lift valve) 79.In this oil pressure synchronization loop portion 80, utilizing shunting miter group valve 78 to make pipe arrangement 81 bifurcateds is 2 systems, on these pipe arrangements 81 electromagnetic switching valve 79 is set.
On the other hand, by the lifting oil hydraulic cylinder 26 (Fig. 8) of rotating frame 25 from downside supporting tray 9, on the front and back position of the lifting frame 23 of rotating frame 25 liftings that make supporting tray 9, use a side of oil hydraulic cylinder 26 as female cylinder 26a (piston rod) with the lifting of position, the left and right sides, with the opposing party as sub-cylinder 26b (plunger case), be connected in series, provide compressed oil with piston one side from the sub-cylinder 26b of piston rod one side direction of female cylinder 26a.Just with 4 liftings among above-mentioned Fig. 8 with the left and right sides cylinder 26 (2 cylinders in left side for example shown in Figure 8) of the front side that is arranged at lifting frame 23 in the oil hydraulic cylinder 26 as female cylinder 26a and sub-cylinder 26b, the left and right sides cylinder 26 (2 cylinders in right side for example shown in Figure 8) that is provided with on the rear side as female cylinder 26a and sub-cylinder 26b, is formed two one group (the female cylinder 26a in one group of ground respectively; Piston rod+sub-cylinder 26b; Plunger case) amounts to 2 groups, each group is connected in series its mother and sons' cylinder (piston rod one side of piston rod 26a is connected with piston one side of plunger case 26b).And, will be connected in piston one side of each the female cylinder 26a on the front and back position of lifting frame 23 with the pipe arrangement 81 of shunting miter group valve 78 bifurcateds of above-mentioned oil pressure synchronous circuit portion 80 by electromagnetic switching valve 79.Piston rod one side of each mother and sons' cylinder 26a and piston one side of each sub-cylinder 26b are connected again.By means of this, form by electromagnetic switching valve 79 compressed oil is offered piston one side of each female cylinder 26a, the structure of compressed oil is provided from piston one side of each sub-cylinder 26b of piston rod one side direction of each female cylinder 26a.
And, in above-mentioned oil pressure synchronization loop portion 80, the bypass circulation 82 that piston one side with each sub-cylinder 26b is connected with the pipe arrangement 81 in the downstream of above-mentioned shunting miter group valve 78 is set for each group.On this bypass circulation 82 electromagnetic switching valve 83 is set.This electromagnetic switching valve 83 is normally closed, by opening and closing this electromagnetic switching valve 83, can regulate the oil mass in the loop circuit that female cylinder 26a and sub-cylinder 26b are set.
In this example, in oil pressure synchronization loop portion 80, bypass circulation 82 is set, still, may not be provided with.Can replace this bypass circulation 82 again, at the sidepiece of sub-cylinder 26b jointing etc. is set, so that can be when periodic maintenance by manual operation replacement or makeup oil.Such structure such as above-mentioned shown in Figure 8 also can be used under the situation about all being made of plunger case 26 with hydraulic cylinder of boosting.
Adopt such structure, under electromagnetic switching valve 83 closing state of bypass circulation 82, electromagnetic switching valve 79 is carried out open and close controlling, by means of this, female cylinder 26a of on the front and back position of lifting frame 23 each and sub-cylinder 26b, distribute the compressed oil pressure that provides synchronous by shunting miter group valve 78, therefore on the front and back position of lifting frame 23, can make compressed oil pressure synchronous in each group.Therefore even before and after storing there be under the situation of vehicle of a great difference weight, be set at suitable size by the ratio that will utilize shunting miter group valve 78 to distribute in the front and back of pallet 9, female cylinder 26a and sub-cylinder 26b in front and back make compressed oil pressure synchronous, can stablize the weight difference of the front and back of supporting tray 9.
Again, because bypass circulation 82 is set in this example as mentioned above, so even oil in the loop circuit of female cylinder 26a and sub-cylinder 26b is set by leakages such as sealings, oil mass needs to adjust, also can pass through the switching of the electromagnetic switching valve 83 of control bypass loop 82, easily regulate the oil mass (oil pressure) in the loop circuit.And by only open this electromagnetic switching valve 83, can only make plunger case 26 actions of this position, therefore when for example being necessary the level of pallet 9 regulated, can regulate the position of cylinder, make pallet 9 be in level by opening and closing electromagnetic switching valve 83.
Figure 11 is the schematic diagram of the connection example of the oil hydraulic cylinder used of the lifting of oil hydraulic circuit shown in Figure 10, (a) is the schematic diagram of the connection example of Figure 10, (b) is other schematic diagrames that connect example.In these figure, describe with the symbol of the formation among above-mentioned Figure 10.Also have, the record of electromagnetic switching valve 79 is omitted.
Shown in the schematic diagram of Figure 11 (a), in the above-mentioned oil pressure synchronization loop portion 80 shown in Figure 10, form to utilize on the front and back position of pipe arrangement 81 that shunting miter group valve 78 will be divided into two systems and pallet 9 about cylinder 26a, 26b be connected in series, keep the weight balancing of pallet 9 from the structure of downside supporting tray 9 with the front and back two groups of mother and sons' cylinders 26a, the 26b that are arranged at pallet 9.
On the other hand, in the Elevator parking apparatus as applicable object of the present invention, the situation of the rotation of following pallet 9 is arranged for the direction conversion of equipped vehicle.Under the situation of these pallet 9 rotations, load on above-mentioned two groups of mother and sons' cylinder 26a, the 26b sometimes reverses because of the relation of the anglec of rotation, even for example on the front portion of the approach axis of vehicle and rear portion, respectively dispose one group of mother and sons' cylinder 26a, 26b respectively, in case make weight before and after carrying that pallet 9 Rotate 180s ° of the vehicle of big-difference be arranged very much, the front and back position of this pallet 9 and the state that reverse position, the left and right sides also can take place, and load situation also reverses simultaneously.Even pallet 9 half-twist load situations are also changed.Therefore the weight difference that produces owing to the variation of load situation causes laod unbalance.Just under pallet 9 non-rotary situations, with the setting pressure of shunting miter group valve 78, for example cylinder setting pressure increasing of heavy front part of vehicle one side, the cylinder setting pressure of light vehicle rear one side is reduced, suitably be set to optimum value and get final product, and under the situation of the structure that makes pallet 9 rotations, unbalanced load acts on mother and sons' cylinder 26a, 26b, under the big situation of this laod unbalance, utilizes 78 of shunting miter group valves to regulate setting pressure and is difficult to realize synchronously.
Therefore, shown in the schematic diagram that other of Figure 11 (b) connect example, employing forms two groups of cylinders altogether that two one group female cylinder 26a (piston rod) and sub-cylinder 26b (plunger case) constitutes with 4 cylinders, simultaneously mother and sons' cylinder 26a, 26b is formed mother and sons' cylinder 26a, 26b with mother and sons' cylinder 26a of locational front and back one side in the left and right sides of pallet 9, the diagonal connection that is connected with the locational front and back the opposing party's in the left and right sides sub-cylinder 26b.And piston rod one side of female cylinder 26a that these diagonal angles are connected is connected in series with piston one side of sub-cylinder 26b, forms and can enough shunting miter group valves 78 compressed oil that distributes be offered each mother and sons' cylinder 26a that organizes, the structure of 26b.Under the situation of this structure, when providing compressed oil by electromagnetic switching valve 79 (Figure 10) to piston one side of each female cylinder 26a respectively, compressed oil can make the sub-cylinder 26b of diagonal position realize that oil pressure is synchronous from piston rod one effluent of this mother and sons' cylinder 26a piston one side to sub-cylinder 26b.Under the situation of this structure,, also can keep the weight balancing of position, the left and right sides of pallet 9 and the weight balancing of front and back position even the allotment ratio of shunting miter group valve 78 is fit in the front and back of pallet 9 size.
That is to say, if the diagonal angle connects, mother and sons' cylinder 26a, the 26b of each group is synchronous respectively in the diagonal position formation combination that load is big and load is little of pallet 9, therefore the unbalanced load that is subjected in each group in the time of rotation is suitably distributed, no matter be with what kind of angle (do not rotate, 90 ° of rotations, 180 ° of rotations) to rotate, big change also can not take place in the load difference between two groups of cylinder 26a, 26b.Even that is to say that adopting the diagonal angle to connect like this carries out the connection of two groups of mother and sons' cylinder 26a, 26b, by making pallet 9 rotations, the position of centre of gravity of the vehicle that carries is on pallet 9, change at fore-and-aft direction and left and right directions, the load that acts on each cylinder 26 changes, the hydraulic pressure that is disposed at the cylinder 26 of front and back position also can be synchronous, can be with the desirable state support unit of weight balancing.And adopt such structure, also can use the electromagnetic switching valve 26 (lift-type electromagnetic valve) of handoff response sensitivity.
Therefore, if adopt the structure shown in Figure 11 (b), even the weight before and after then storing has under the situation of vehicle of a great difference, take place pallet 9 front and back weight difference and wait the active position variation of the load that causes by rotation, also can make the compressed oil pressure of the mother and sons' cylinder 26a, the 26b that dispose on front and back position and the position, the left and right sides synchronous, realize stable support.
Also have, also can utilize shunting miter group valve 78 to be divided into 2 systems,, make the piston rod upper end of these mother and sons' cylinders 26a, 26b and the soffit mechanical bond of the rotating frame 25 (Fig. 8) of supporting tray 9 simultaneously with mother and sons' cylinder 26a, 26b supporting tray 9.Again, preferably they adopt desirable structure corresponding to the configuration of the length of pallet 9, mother and sons' cylinder 26a, 26b that lifting is used and the conditions such as vehicle weight that can store.
Figure 12 (a)～(c) utilizes vehicle lifting pallet to be sent into the floor map of the lateral transfer action of carport.Figure 13 (a)～(c) is the lateral view that schematically shows the duty of locking device.The horizontal drive actions of the pallet that above-mentioned rotating driving device 30 and locking device 50 is carried out below with reference to these accompanying drawings describes.The sending into of pallet 9 (storage) moved with to take out of (reception) action (crosswise movement) identical, and therefore the action of sending into pallet 9 describes for example.
Shown in Figure 12 (a), utilize two motor 33,34 (Fig. 5) of rotating driving device 30 that the 1st arm 35 is rotated on prescribed direction, so that the angle that the 1st, the 2nd arm 35,36 is formed is constant, and will cooperate roller 44 to cooperate with mating groove 49.Stage before making these pallet 9 horizontal moving, from the holding state of the locking device 50 shown in Figure 13 (a), shown in Figure 13 (b), make piston rod 53 elongations, make coupling member 51 outstanding with this, be stuck on the mating component 52 of carport 7 to the direction of carport 7.With this vehicle lifting 13 and carport 7 are linked.
Then, shown in Figure 12 (b), suitably drive 2 motor 33,34, so that pipe arrangement roller 44 makes pallet 9 move to width.By means of this, the wheel 11 of pallet 9 moves along track 27,8, and pallet 9 is laterally moved to carport 7.At this moment, vehicle lifting 13 links by means of locking device 50 and carport 7, therefore can pallet 9 be moved enough stable horizontal shift actions.
Shown in Figure 12 (c),,, and make cooperation roller 44 break away from mating grooves 49 (shown in 2 locking wires) then so that the 1st arm 35 does not rotate in case pallet 9, just makes 36 rotations of the 2nd arm by income carport 7.By means of this, finish moving into of pallet 9.At this moment, shown in Figure 13 (c), piston rod 53 also shrinks, and utilizes the coupling member 51 and the binding of the mating component 52 of carport 7 to be disengaged.
As mentioned above, in this explanation, the action of moving into pallet 9 is illustrated, and when carport 7 is taken out of pallet 9, moves with make two arms 35,36 according to opposite step.Also have, the applicant's application Japanese Patent Application will be described in detail the driving of the 1st, the 2nd arm 35,36 for 2001-239116 number.
Below the vehicle lifting 13 that constitutes is as mentioned above described in the action that melt pit carries out.Figure 14 is the longitudinal plan that the rotating frame of expression vehicle lifting shown in Figure 4 is in the state on the position of rotation.Figure 15 is the longitudinal plan of the state of the pallet lateral transfer direction of expression vehicle lifting shown in Figure 4 when switching.In these figure, be that example describes with above-mentioned oil hydraulic circuit shown in Figure 8.
At first, be the state that vehicle M in the warehouse-in portion 20 (Fig. 1) goes out warehouse-in at above-mentioned state shown in Figure 4, be to remain untouched vehicle lifting 13 is risen simultaneously, carport 7 arbitrarily make pallet 9 laterally move can stocking tray 9 state.Under this state, the vehicle road 10 of pallet 9 and the vehicle upper surface on the deck 22 of usefulness (ground that enters) up and down form same plane.
Therefore, going out to put in storage floor, the vehicle road 10 of pallet and vehicle be the deck 22 same levels of usefulness up and down, form the easy structure up and down for the user.And, when vehicle lifting 13 arrives out the warehouse-in floor, lifting frame 23 and rotating frame 25 etc. carry out entering with the lifting of pallet 9 of vehicle M with the state that floats from the ground of melt pit 21 and rotate, and therefore arrive out the warehouse-in floor at every turn, can not clash into the impact and the noise on melt pit floor.And the actuator of locking device 50 adopts piston rod 53, and the lifting of rotating frame 25 is simultaneously adopted plunger case 26 with driving machine, utilizes common oil pressure unit 55 to drive these cylinders, therefore can seek the densification of device.
Again, under this state, make the piston rod 28 of the plunger case 26 of rotating frame 25 liftings be in lower end position, pallet 9 is in the state of its wheel 11 mountings on horizontal moving track 27.And therefore rotating frame 25 is in non-rotating state owing to the rotation of its engagement tabs 48 is stopped by pod member 47, can keep making the pallet 9 stable states of supporting of equipped vehicle M.Pallet 9 is stored under the situation of carport 7 from this state, be arranged in the mating groove 49 on right side of pallet 9, be combined with cooperation roller 44, so after on the position of the carport 7 that rises to regulation, pallet be stored in the carport 7 in the left side of the lift path 12 that is arranged at Fig. 1.
STA representation shown in Figure 14 makes the state of pallet 9 rotations.As shown in the figure, make under the situation of pallet 9 rotations, utilize rotating frame 25 to make pallet 9 promote ormal weight.This lifting utilization is arranged at the elongation of the plunger case 26 of lifting frame 23 and carries out.In this example by making plunger case 26 elongation, horizontal c when rotating frame 25 is risen to the lifting rotation of Fig. 7.With this rotating frame 25, pallet 9 is promoted from lifting frame 23 upward with vehicle M is in aggregates.By means of this, the pod member 47 that is provided with on the engagement tabs 48 that is provided with on the rotating frame 25 and the lifting frame 23 forms non-mated condition, forms mated condition with the engagement protrusion 43 that has on the front end of the 1st arm 35 of the rotating driving device 30 that is provided with on the rotating frame 25.Under this state, the upper surface on the deck 22 of usefulness is high slightly up and down than vehicle for the lowest surface of pallet 9.
And the 1st arm the 35, the 2nd arm 36 usefulness the 1st motor 33 of rotating driving device 30 makes its rotation in aggregates, and by means of this, rotating frame 25 rotations that swivel bearing 29 is supported make pallet 9 rotations.When carrying out this rotation, control the anglec of rotation of the 1st motor 33,, carry out this rotation with the angle (for example 90 °, 180 °) of regulation by means of this.
Like this, the floor when being higher than vehicle and entering by the rotation level of pallet 9 of using the warehouse-in step as mentioned above, makes floor when vehicle enters when lifting (lifting with deck 22) and pallet vehicle road 10 pars.
Figure 15 is the longitudinal plan of the state of the pallet lateral transfer direction of expression vehicle lifting shown in Figure 4 when switching.State shown in Figure 4 is the state that is arranged at stocking tray 9 on the carport 7 in left side of lift path 12, below the change action that it is switched to the state of stocking tray 9 on the carport 7 that is provided with on the right side of lift path 12 is described.
As shown in the figure, in that pallet 9 is moved laterally under the situation of carport 7 on right side, utilize plunger case 26 that rotating frame 25 is promoted a little.The lifting capacity of this rotating frame 25 is, the engagement tabs 48 that is arranged at rotating frame 25 keeps the state that cooperates with the pod member 47 that is arranged at lifting frame 23 constant, the cooperation roller 43 of the 2nd arm breaks away from downwards from the mating groove 49 of pallet 9, be arranged at engagement protrusion 43 and pod member 45 on the front end of the 1st arm 35 of rotating driving device 30 and be in non-mated condition, the horizontal moving direction of above-mentioned Fig. 7 switches the amount of horizontal b.
Under this state, if utilize rotating driving device 30 that the 1st arm 35 and the 2nd arm 36 are rotated to left integrally, then the rotation of rotating frame 25 is merely able to make arm 35,36 to move to the left under the state of the prevention that is subjected to being arranged at the pod member 47 on the lifting frame 23.Thereafter, because the compressed oil of plunger case 26 is discharged, rotating frame 25 relies on own wt to descend, and the wheel 11 of pallet 9 is in the state on the cross track 27 that places lifting frame 23.Form this state, the cooperation roller 44 of rotating driving device 30 is matched with in the mating groove 49 that is provided with on the left side soffit of pallet 9.By means of this, form the 1st arm 35 of Fig. 4 and the state that the left of the 2nd arm 36 in figure moves.
Also have, in above-mentioned example, the structure that employing drives the piston rod 53 of the plunger case 26 of hoist and locking device 50 with same oil pressure unit 55, but these members also can constitute with other structures, perhaps also can adopt independent oil pressure unit to drive respectively, be not limited to above-mentioned example.
Also have, above-mentioned example has been represented an example, in the scope of the main idea of not damaging the present patent application various changes can be arranged, and the present patent application is not limited to above-mentioned example.
