The car transporter that No. 2532158 communique of Japanese Patent (patent documentation 1) recorded has been shown in Figure 12 and Figure 13.This known car transporter be can free inclination in the rearward end that is installed on the auxiliary frame 112 on transport trolley vehicle frame tilting rack 103 pivots prop up, and on this tilting rack 103, arrange can before and after the loading stage 104 that moves freely.And this known car transporter can enough 1 telescopic cylinder 151(Figure 13) complete the tilting action of tilting rack 103 and moving forward and backward of loading stage 104 simultaneously.
As shown in figure 13, tilting rack 103 has exterior part 131 and the inner component 132 that can mutually slide, and the length direction pars intermedia of exterior part 131 is propped up the rearward end at auxiliary frame 112 by fulcrum 108 pivots.Between the leading section of the inner component 132 of tilting rack 103 and auxiliary frame 112, be provided with the connecting rod mechanism 109 being formed by the 1st～3rd connecting rod 191,192,193.
Each connecting rod 191,192,193 of this connecting rod mechanism 109 is as shown in Figure 12 (B) and figure 12 (C), and the 2nd connecting rod 192 adopts shorter connecting rod, and the 3rd connecting rod 193 adopts longer connecting rod.And these the 1st～3rd connecting rods 191,192,193 are assembled as shown in Figure 13, structure very complex.That is rearward end, the 1st connecting rod 191(tape guide groove) is propped up on auxiliary frame 112 by pivot 194 pivots and can be swung up and down.The base end part of the 2nd connecting rod 192 is by the leading section of pivot 195 pivot Zhi 1 connecting rods 191, and the leading section of the leading section of the 2nd connecting rod 192 and the 3rd connecting rod 193 is being propped up by pivot 196 pivots.The base end part side that the roller chimeric with the guide groove of the 1st connecting rod 191 197, the 3 connecting rods 193 are installed at the base end part of the 3rd connecting rod 193 can move along the guide groove of the 1st connecting rod 191.And enter under the state of frame at the loading stage shown in Figure 12 (A), the 2nd connecting rod 192 of connecting rod mechanism 109 and the 3rd connecting rod 193 become the forwards posture of lodging.
In addition, at the leading section of the 2nd connecting rod 192, be provided with bearing portion 198(Figure 13 of groove shape), be located at tilting rack 103(inner component 132) the axle 133 of leading section chimeric can freely engage mode and this bearing portion 198 of disengaging.At the loading stage shown in Figure 12 (A), enter under frame state, although the 2nd connecting rod 192 forwards lodges, under this posture, bearing portion 198 is at the axle 133(Figure 13 than tilting rack leading section) lean on rear a lot of position with the state standby to front opening.
This known car transporter enters frame state from the loading stage shown in Figure 12 (A) makes telescopic cylinder 151(Figure 13) while dwindling, the inner component 132 of tilting rack 103 retreats (tilting rack 103 dwindles), at the axle 133 of inner component leading section, embed after the bearing portion 198 with posture standby forward, the 2nd shorter connecting rod 192 just erects.Now, as shown in Figure 12 (B), the recede angle of regulation of tilting rack 103, simultaneously loading stage 104 rearward moves and makes ground connection roller 143 ground connection of loading stage rearward end.Then, while further dwindling telescopic cylinder 151 from the state of Figure 12 (B), just as shown in Figure 12 (C), compared with the 3rd long connecting rod 193, erect and this tilting rack 103 is tilted, until the rearward end ground connection of tilting rack 103, simultaneously loading stage 104 displacements, until become the posture with day water level land ground connection.
No. 2532158 communique of patent documentation 1 Japanese Patent
Yet, although the car transporter of known (patent documentation 1) shown in Figure 12 and Figure 13 is to realize the tilting action of tilting rack 103 and moving forward and backward of loading stage 104 with 1 telescopic cylinder 151 simultaneously, so can common drive system, but for making the connecting rod mechanism 109(that tilting rack 103 tilts use the 1st～3rd these 3 connecting rods) complex structure of part and quite heavy, and telescopic owing to tilting rack 103 will being made, so the structure of tilting rack 103 parts is also very complicated.
Therefore the known car transporter shown in Figure 12 and Figure 13 has the problem of the Heavy Weight of high and connecting rod mechanism 109 parts of number of parts is many, assembleability is poor, whole cost.
In addition, when using aforementioned link mechanism 109 as the tilting action supporting device of tilting rack 103 as this known car transporter, when tilting rack 103 is done sweptback action, from the state of Figure 12 (A) till the state of Figure 12 (B), the 2nd connecting rod 192 is by pivot 195(Figure 13) centered by swing, and from the state of Figure 12 (B) till the state of Figure 12 (C) is to maintain under leg-of-mutton state at each connecting rod to swing (109 minutes 2 stages of connecting rod mechanism swing) centered by pivot 194.When connecting rod mechanism 109 so swings, the tilting action speed of the tilting rack 103 corresponding with the stroke of telescopic cylinder 151 can change in stand up starting stage, the intermediary of standing up and the terminal stage of standing up of connecting rod 109, and the tilting action of tilting rack 103 level and smooth (constant speed ground) carries out.Especially at tilting rack 103, from heeling condition, lodge to chord position while putting, when approaching into frame posture (flat-hand position), lodging speed is accelerated, thereby can cause collision to tilting rack 103 finish time in lodging.
Also have, while using connecting rod mechanism 109 as the tilting action supporting device of tilting rack 103, at the initial stage of standing up of this connecting rod mechanism 109, need to have very large cylinder output, therefore will use the telescopic cylinder 151 of the large output (at high price) that can meet the need.
For this reason, the object of the present invention is to provide enough 1 telescopic cylinders of a kind of energy to realize the tilting action of tilting rack and the car transporter moving forward and backward of loading stage simultaneously, not only can make tilting rack do the light weight simple in structure that tilting action is used, and can make tilting rack do smoothly tilting action.
Summary of the invention
In order to address the above problem, the present invention has following structure.In addition, the present invention is can make loading stage recede and rearward to move, take vehicle is put to car transporter on loading stage as object.
The car transporter of technical solution of the present invention 1 has: vehicle body, and this vehicle body has vehicle frame; Tilting rack, this tilting rack is supported on the rearward end position of vehicle frame and can freely does tilting action; Loading stage, this loading stage is supported on tilting rack and can moves freely along vehicle body fore-and-aft direction; Tilting action device, this tilting action device has the telescopic cylinder that is located between tilting rack and loading stage, loading stage is moved along vehicle body fore-and-aft direction with respect to tilting rack, and can make described tilting rack do tilting action by the expanding-contracting action of telescopic cylinder.
On vehicle frame, pair of right and left auxiliary frame can be set, but also can not establish auxiliary frame.In the scope of claim of the present invention, even there is the structure of auxiliary frame, this auxiliary frame is included and shown as vehicle frame.
There is the long tilting rack of pair of right and left.And this tilting rack is supported on the rearward end position of vehicle frame (or auxiliary frame) and can freely does tilting action, but this support can be both to come pivot to prop up tilting rack with fulcrum, can be also with roller bearing tilting rack, this tilting rack to be supported under the state that can move forward and backward on the rearward end position of vehicle frame (or auxiliary frame).When the state support tilting rack moving forward and backward, the other telescopic cylinder that this tilting rack is moved forward and backward can be set.
At the rear end of loading stage lower surface, the ground connection roller rolling on the ground can be set.In addition, the rearward end of loading stage can install fluctuating that loading vehicles uses freely involve plate.
For make tilting action device that tilting rack does tilting action by being arranged on guide rail, telescopic cylinder on vehicle frame, be arranged on the cylinder barrel of telescopic cylinder and the roller moving along guide rail forms.
Guide rail has pair of right and left.This guide rail can directly be fixed on vehicle frame, but if the structure of auxiliary frame (pair of right and left) is set on vehicle frame, can be by guide rails assembling on this auxiliary frame.In addition, be set as making tilting rack to do smoothly tilting action when telescopic cylinder is done expanding-contracting action the shape of this guide rail (the guiding rail bar of roller described later).
Telescopic cylinder adopts the cylinder with quite long stroke.But, this telescopic cylinder only needs 1.This telescopic cylinder is that the front portion of cylinder rod and tilting rack is linked, and cylinder barrel is mounted to the state that can move up in vehicle body front and back along tilting rack.Cylinder barrel is in vehicle body front and back, to move up under the state that maintains parallel posture with respect to tilting rack during in side-looking.
The roller that can move along guide rail is installed on the cylinder barrel of telescopic cylinder, and rear one side shifting by this roller direction guiding rail recedes tilting rack gradually.; tilting rack is supported on the rearward end position of vehicle frame (or auxiliary frame) and can free inclination; and be under the state of keeping parallelism posture, to move forward and backward from the side with respect to tilting rack at cylinder barrel; once therefore telescopic cylinder extends; the roller being arranged on cylinder barrel rearward moves along guide rail, thereby can tilting rack be receded through cylinder barrel.
In addition, guide rail has the length that can guide in the whole moving range of roller, and this roller is mobile in the whole flexible scope of telescopic cylinder.
Between tilting rack and loading stage, be provided with a times speed variator, this times of speed variator can make loading stage, and with respect to the stroke of telescopic cylinder, the amount with 2 times moves forward and backward.Owing to only depending on the flexible stroke of telescopic cylinder can not guarantee the amount of moving forward and backward that loading stage is enough, therefore to use this times of speed variator.This times of speed variator can adopt chain or steel wire etc. is wound up into the structure on pulley.
The car transporter of technical solution of the present invention 1 can the elongation action by telescopic cylinder complete rearward the moving of recede action and loading stage of the tilting rack of being realized by tilting action device simultaneously, thereby makes loading stage drop to the approximate horizontal position of Near Ground.But, in order to make loading stage drop to the approximate horizontal position of Near Ground, loading stage is tilted with respect to tilting rack, thereby the tilt angle varied that makes loading stage becomes than till the little leaning angle of the leaning angle of tilting rack, specifically loading stage is arranged to can by loading stage leading section a bit centered by and with respect to tilting rack, do tilting action.And, by being extended, telescopic cylinder makes after the rearward end ground connection of loading stage, and can be by further making telescopic cylinder extend the leaning angle that gradually reduces loading stage.
The car transporter of technical solution of the present invention 1 has following functions.First, at loading stage, enter under frame state, telescopic cylinder is reduced to minimum, makes to be arranged on the position of close front end that roller on telescopic cylinder is positioned at guide rail, and tilting rack is bearing on vehicle frame with flat-hand position.At this loading stage, enter under the state of frame, loading stage is supported with flat-hand position on the position near vehicle body the place ahead.
Then, in order to make loading stage enter frame state from loading stage, move to the position of loading posture, telescopic cylinder is extended.So, the cylinder barrel that is accompanied by this telescopic cylinder rearward moves along tilting rack, and the roller being arranged on cylinder barrel rearward moves along guide rail, makes thus tilting rack gradually recede through cylinder barrel.In addition, once telescopic cylinder extends, loading stage rearward moves on tilting rack with regard to the speed of extending 2 times of speed because of the effect of times speed variator with telescopic cylinder thereupon.
Then, by loading stage is rearward moved, until the rear end lower surface of loading stage (ground connection roller) ground connection can make this loading stage become the posture of loading vehicles.Yet, thereby make telescopic cylinder extend the moment of the rear end lower surface ground connection that makes loading stage, the leaning angle of loading stage is about 10 °, can load the vehicle of general overall height, but under this state, the leading section of loading stage is positioned at than forward a lot of position, the rear end of tilting rack, thereby this loading stage also has with respect to tilting rack mobile leeway rearward.
Then, once telescopic cylinder further be extended from the state (loading stage leaning angle is about 10 °) of above-mentioned loading stage rearward end ground connection, the leaning angle of tilting rack can further increase (finally making tilting rack rear end ground connection), and along with loading stage further retreats (ground connection roller rolls on the ground), the height of loading stage front portion reduces, and now the leaning angle of this loading stage diminishes gradually.Then, till loading stage can retreat near the position its leading section arrival tilting rack rearward end, but under the state till near the position rearward end that retreats into loading stage leading section arrival tilting rack, this loading stage leading section is reduced to quite low position, thereby makes loading stage be reduced to the approximate horizontal position of Near Ground.The approximate horizontal position of so-called Near Ground also comprises that loading stage is with the state of very mild leaning angle (for example leaning angle of 3～4 ° of left and right) ground connection.
Adopt the car transporter of technical scheme 1, guide rail has the length that can guide in the whole moving range of roller, and this roller is mobile in the whole flexible scope of telescopic cylinder, therefore at telescopic cylinder from complete deflated state till in the roller moving range of extending completely, this roller can getaway.Therefore in compartment from entering frame state till the process moving in the whole moving range of vehicle loading posture state, roller by guide rail support.
In the time will making loading stage from vehicle loading posture state income transport trolley (vehicle frame), with the order that the action with to above-mentioned vehicle loading attitude change is contrary, carry out.
The invention of technical solution of the present invention 2 is additional following structures on the car transporter of technique scheme 1.
First, the rearward end at tilting rack arranges downward support foot.And on guide rail, from body forward structure one side, form continuously the portion of being inclined upwardly, horizontal part and down slop portion.The leaning angle of down slop portion is set tilting rack while moving in the scope of roller in this down slop portion for can maintain roughly fixing inclination attitude.And, at roller, being positioned under the state of down slop portion, support foot contacts with ground.
Adopt the car transporter of technical scheme 2, once enter frame state from loading stage, telescopic cylinder is extended, roller just rearward moves along guide rail, make thus tilting rack gradually recede, loading stage rearward moves with respect to tilting rack simultaneously, thereby is first that loading stage rearward end contacts (posture that loading stage becomes the vehicle that can load general overall height) with ground.
Yet, tilting rack is at the support of vehicle frame rearward end (the 1st supporting portion) and supported on directed roller part (the 2nd supporting portion) these 2 positions on guide rail at first, once roller rearward moves gradually along rail sections, distance between the supporting portion of these 2 positions just shortens (it is unstable that the posture of tilting rack becomes gradually) gradually, but as mentioned above, the moment contacting with ground in loading stage rearward end, between the support (the 1st supporting portion) of roller position (the 2nd supporting portion) and vehicle frame rearward end, also has suitable distance, therefore the posture of tilting rack can also remain stable.
Then, once telescopic cylinder further be extended from the moment of above-mentioned loading stage rearward end ground connection, roller will further approach the support of vehicle frame rearward end and the posture of tilting rack is changed to unsettled direction gradually, but in the moment of top portion that arrives the down slop portion of guide rail at this roller, the support foot of the rearward end of tilting rack just contacts with ground.In addition, arrive on the position of top portion of down slop portion of guide rail at roller, between the support (the 1st supporting portion) of this roller (the 2nd supporting portion) and vehicle frame rearward end, also existence can not destroy the distance of the stability of tilting rack.Thereby, when loading stage is done landing operation, before the support foot ground connection of tilting rack rearward end, support between 2 supporting portions (the 1st supporting portion and the 2nd supporting portion) of this tilting rack and keeping supporting with stabilized conditions the interval of tilting rack.
Once and the support foot ground connection of tilting rack rearward end, tilting rack is just supported on the support of vehicle frame rearward end and these 2 distances of the support foot of tilting rack rearward end 2 positions quite far away, therefore can guarantee the stability of the posture of this tilting rack.
Then (support foot is after touchdown time), once telescopic cylinder further be extended for loading stage is further slowly tilted, roller rearward moves along the down slop portion of guide rail, but this down slop portion is the tilting action effect to tilting rack not, therefore under maintaining the state of posture, this tilting rack only have loading stage rearward to move (height of loading stage front portion reduces gradually), and till retreating near the position rearward end that loading stage leading section arrives tilting rack, under this state, identical with the situation of technique scheme 1, loading stage becomes very mild leaning angle (for example leaning angle of 3～4 ° of left and right).
The invention of technical solution of the present invention 3 is on the car transporter of technique scheme 1 or 2, rearward end at vehicle frame is installed roller, on this roller, load tilting rack and enable to move forward and backward with respect to vehicle frame, simultaneously between the rearward end of vehicle frame and tilting rack, the special-purpose telescopic cylinder that tilting rack is moved forward and backward being set.
So-called vehicle frame in technical scheme 3, if auxiliary frame is installed on this vehicle frame, comprises this auxiliary frame interior.
The car transporter of technical scheme 3 makes tilting rack move forward and backward with respect to vehicle frame by utilizing tilting rack to move forward and backward special-purpose telescopic cylinder, can move forward and backward the tilting action center (using the part of the roller bearing of vehicle frame rearward end) of adjusting this tilting rack.And, by the bearing position of tilting rack is rearward moved, can extend the distance from this bearing position to tilting rack rearward end, once carry out the loading stage ground connection operation elongation of the main telescopic cylinder (operation) under this state, just shortened the time till tilting action by tilting rack makes tilting rack rearward end (if be provided with support foot, being exactly this support foot) ground connection.When loading stage ground connection operates, once shorten till the time of tilting rack rearward end (or support foot) ground connection, just can shorten the load time applying on by the roller of rail guidance.

Because each guide rail 2,2 has the length that can guide in the whole moving range of each roller 55,55, and each roller the 55, the 55th moves in the whole flexible scope of telescopic cylinder 51, therefore in the whole flexible scope of telescopic cylinder 51, each roller 55,55 can getaway 2,2.; in the complete deflated state of the telescopic cylinder 51 from shown in Fig. 1 till in the whole flexible scope of the complete elongation state of the telescopic cylinder 51 shown in Fig. 8; roller 55 is guided by guide rail 2 continuously, thereby this roller 55 can getaway 2 in the whole moving range of roller 55.
The leaning angle of the down slop portion 23 of guide rail 2 is set tilting rack 3 when roller 55 moves in the scope of this down slop portion 23 for can maintain roughly fixing inclination attitude.That is,, when roller 55 moves along this down slop portion 23, tilting rack 3 is not done to tilting action.
In addition, at each, on the outside face of underarm 54,54, as shown in Figure 2 to 4, roller 59,59 is installed respectively.Each roller 59,59 and to be arranged on each rollers 57,58 of cylinder barrel 52 front and back same, embeds in each of the frame 3,3 that tilts in guide groove 31,31.Above-described embodiment is that each roller 59,59 is embedded in each guide groove 31,31 singly, but can be also, in the front and back of each arm 54,54,2 rollers 59 are respectively set, and each 2 rollers are embedded respectively in each guide groove 31,31.In this case, each arm 54,54 is guided with more stable state.
The amount that loading stage 4 is arranged on each tilting rack 3,3 by times speed variator A with 2 times of the strokes of telescopic cylinder 51 moves forward and backward.This times of speed variator A has the chain 7,7 of moving body 6 and left and right.
Moving body 6 use coupling plates 62 link left and right framework 61,61, and on the inside face of each framework 61,61, each installs 2 of front and back (amounting to 4) rollers 63,63 simultaneously.The left and right sides roller 63,63 of moving body 6 is chimeric with the export-oriented guide groove 32,32 of each tilting rack 3,3 respectively, and moving body 6 can be moved forward and backward along each tilting rack 3,3.But, this moving body 6 is to move forward and backward maintaining all the time under the state of the posture parallel with each tilting rack 3,3 from the side.
As shown in Figures 3 and 4, each chain 7,7 of left and right has respectively the 1st cutting apart chain 71 and the 2nd and cut apart chain 72 of being divided into two.In other embodiments, this chain 7 also can adopt 1 ring chain.In addition, in other embodiments, also can replace chain 7 with metal filament.
In the present embodiment, the following mode of each chain 7,7 use is installed.First in leading section and the rearward end of the cylinder barrel 52 of telescopic cylinder 51, in the left and right of cylinder barrel 52, the pulley (amounting to 4) 56,56 that volume chaining bar is used is installed in each outside respectively.In the present embodiment, each pulley the 56, the 56th, coaxially arranges in 2 groups of above-mentioned front and back roller 57,57,58,58 inner side separately.As shown in Figures 3 and 4, under each the 1st state of cutting apart on chain 71,71 is hung on each rear side pulley 56,56 at volume, this each the 1st anterior end of cutting apart chain 71,71 is fixed on the coupling plate 62 of moving body 6, and this each the 1st rear end of cutting apart chain 71,71 is fixed on tilting rack 3,3.And under each the 2nd state of cutting apart on chain 72,72 is hung on each front side pulley 56,56 at volume, this each the 2nd anterior end of cutting apart chain 72,72 is fixed on the coupling plate 62 of moving body 6, and this each the 2nd rear end of cutting apart chain 72,72 is fixed on tilting rack 3,3.
With fulcrum 64(, be provided with coaxially 2 of left and right) loading stage 4 is propped up on moving body 6 with some pivots near position loading stage leading section.; as shown in Figures 3 and 4; by making fulcrum 64(with reference to Fig. 1, Fig. 2, Fig. 5) connect respectively on each framework 61,61 of the left and right of moving body 6 the axis hole 64a forming and the axis hole 64b forming near the position leading section of each underframe 42,42 of the left and right of loading stage 4, loading stage 4 is propped up on moving body 6 with some pivots from the side.
And, once telescopic cylinder 51 is flexible, this times of speed variator A just each pulley 56,56 by front and back and chain 7(the 1st cut apart chain 71 and the 2nd and cut apart chain 72), moving body 6 is moved forward and backward with 2 times of length of the stroke of telescopic cylinder 51, thus make loading stage 4 together with moving body 6 also 2 times of length with the stroke of telescopic cylinder 51 move forward and backward.
Once telescopic cylinder 51 be extended gradually from the frame posture that enters shown in Fig. 1, loading stage 4 just through the heeling condition (loading stage leaning angle is about 10 °) of ground connection roller 43 ground connection of loading stage rearward end as shown in Figure 6, and through the state of support foot 34 kiss the earths of the rearward end of the tilting rack 3 shown in Fig. 7, become the approximate horizontal position that loading stage 4 as shown in Figure 8 drops to Near Ground.The approximate horizontal position of so-called Near Ground also comprises that loading stage 4 is with the state of very mild leaning angle (for example 3～4 ° of left and right) ground connection.
As shown in Figure 6, under the loading stage heeling condition of 43 touchdown times of ground connection roller of loading stage rearward end, 4 one-tenth general leaning angles (approximately 10 °) that can load the vehicle of general overall height of loading stage, can be to carry out under the state of Fig. 6 in the time will loading the vehicle of general overall height.Under the state of this Fig. 6, the rearward extension elongation of loading stage 4 is shorter, at the working space of front and back hour effectively.
Again as shown in Figure 8, at loading stage 4, drop under the state of approximate horizontal position of Near Ground, one-tenth can load the gentle slope angle (3～4 ° of left and right) of the vehicle that sports type car one class overall height is lower, in the time will loading the lower vehicle of overall height, with the state of Fig. 8, carries out.Under the state of Fig. 8, can make the leaning angle of loading stage 4 extremely mild, but the length that loading stage 4 rearward stretches out is longer, the larger place of working space before and after being therefore suitable for.Certainly, under the state at the gentle slope angle of Fig. 8, also can load the vehicle of general overall height.
Tilting rack 3 is in the support 8(of the rearward end of auxiliary frame 12 the 1st supporting portion at first) and supported on directed these 2 positions of roller 55 parts (the 2nd supporting portion) on guide rail 2, and once roller 55 rearward moves gradually along guide rail 2 parts, distance between the supporting portion of these 2 positions (the 1st supporting portion of support 8 and the 2nd supporting portion of roller 55 parts) just shortens (it is unstable that the posture of tilting rack 3 becomes gradually) gradually, but as shown in Figure 6, the moment contacting with ground in loading stage rearward end (roller 43), supporting 8(the 1st supporting portion of the position of roller 55 (the 2nd supporting portion) and auxiliary frame rearward end) between, also has suitable distance, therefore the posture of tilting rack 3 can also maintain stability.
Then, once telescopic cylinder 51 further be extended from the touchdown time of the loading stage rearward end shown in Fig. 6 (roller 43), on guide rail 2, directed roller 55 just further approaches the support 8 of auxiliary frame rearward end, the posture of tilting rack 3 is changed to unsettled direction gradually, but at this roller 55, arrive moment of top portion of the down slop portion 23 of guide rails 2, as shown in Figure 7, support foot 34 ground connection of the rearward end of tilting rack 3.Under the state of this support foot ground connection, only have the front portion of loading stage 4 to be loaded on tilting rack 3, make the leaning angle of loading stage 4 more milder than the state of Fig. 6.
At roller 55, arrive on the position of top portion of down slop portion 23 of guide rails 2 this roller 55(the 2nd supporting portion) with support 8(the 1st supporting portion of auxiliary frame rearward end) between also existence can not destroy the distance of the stability of tilting rack 3.Thereby, when doing loading stage landing operation, before support foot 34 ground connection of tilting rack rearward end, support between 2 supporting portions (the 1st supporting portion 8 and the 2nd supporting portion 55) of this tilting rack 3 and keeping supporting with stabilized conditions the interval of tilting rack 3.
Once and support foot 34 ground connection of tilting rack rearward end, as shown in Figure 7, tilting rack 3 is just supported on the support 8 of auxiliary frame rearward end and support foot 34 these 2 distances of tilting rack rearward end 2 positions quite far away, therefore can guarantee the stability of the posture of this tilting rack 3.
Once telescopic cylinder 51 further be extended so that loading stage 4 further gently tilts from the state of Fig. 7, roller 55 just rearward moves along the down slop portion 23 of guide rail 2, and this down slop portion 23 is for the tilting action of tilting rack 3, therefore under maintaining the state of posture, this tilting rack 3 only have loading stage 4 rearward to move (height of loading stage front portion reduces gradually).Then, as shown in Figure 8, under near the state of the position rearward end that retreats into loading stage leading section arrival tilting rack 3,4 one-tenth very mild leaning angles of loading stage (for example leaning angle of 3～4 ° of left and right).
The method of work of the car transporter of the 1st embodiment is below described.
Loading stage at Fig. 1 enters under frame state, telescopic cylinder 51 dwindles completely, near position (the place ahead of the portion 21 that is inclined upwardly) front portion to the roller 55 of underarm 54 in guide rail 2, tilting rack 3 becomes flat-hand position, and loading stage 4 also maintains flat-hand position on front position.When loading stage 4 is when entering frame posture, near the leading section of loading stage underframe 42,42, position is bearing on moving body 6 by above-mentioned fulcrum 64, and the lower surface of loading stage underframe 42,42 puts at the upper surface of each auxiliary frame 12,12 (slipping plate 14,14) and above can be free to slide.
In order to make loading stage 4 become the posture that can put vehicle, telescopic cylinder 51 is extended.So, cylinder barrel 52 just rearward moves, and be arranged on to the roller (having pair of right and left) 55 on underarm 54 just through the portion that is inclined upwardly 21 of guide rail 2 and move to horizontal part 22, make tilting rack 3 do tilting action, simultaneously loading stage 4 utilizes times speed variator A and rearward moves with 2 times of length of telescopic cylinder elongation, makes ground connection roller 43 ground connection of loading stage rearward end.Then, once thereby make to involve plate 44 ground connection that rearward lodges, as shown in Figure 6, become the posture of the vehicle S that can load general overall height.
For loading stage 4 is further slowly tilted from the state of Fig. 6, telescopic cylinder 51 is further extended.So, be first as shown in Figure 7, at the roller 55 to underarm 54, arrive moment of position, top of the down slop portion 23 of guide rails 2, support foot 34 ground connection of tilting rack rearward end.Now, although it is less than the leaning angle of tilting rack 3 that the leaning angle of loading stage 4 becomes, but because this loading stage 4 can be in fact moving body 6 with respect to tilting rack 3(centered by a bit (position of fulcrum 64) of loading stage leading section) do tilting action, therefore can have no to hinder to make loading stage 4 do tilting action with respect to tilting rack 3.
Then, once telescopic cylinder 51 further be extended from the state of Fig. 7, roller 55 to underarm 54 just rearward moves (now the leaning angle of tilting rack 3 is constant) along the down slop portion 23 of guide rail 2, and as shown in Figure 8, at this roller 55, arrive moment of terminal part of the down slop portion 23 of guide rails 2, release.
Under the state of Fig. 8, loading stage 4 drops to the approximate horizontal position of Near Ground, and this loading stage 4 keeps stable with very mild leaning angle (for example 3～4 ° of left and right).And under the state of the loading stage gentle slope shown in Fig. 8, the much less vehicle of general overall height, even if the lower vehicle of overall height can not load yet not difficultly.
In addition, telescopic cylinder 51 can carry out stepless elongation at the 1st grade of elongation state from Fig. 6 to the final elongation state of Fig. 8, and can set loading stage leaning angle according to the overall height that betransported vehicle S, or set according to working space or landform the length (for example using with the state of Fig. 7) that loading stage 4 stretches out backward.
In the time loading stage 4 will being put to state and enters frame from vehicle, can be by making telescopic cylinder 51 dwindle to carry out.
As mentioned above, the car transporter of the 1st embodiment can complete the tilting action of tilting rack 3 and moving forward and backward of loading stage 4 by enough 1 telescopic cylinders 51 simultaneously.In addition, as the tilting action device 5 of tilting rack 3, be to form with guide rail 2, telescopic cylinder 51 and the roller 55 that is arranged on cylinder barrel 52, so this tilting action device 5 simple in structure (number of parts is few, assembleability is good) and lightweight, overall cost is low simultaneously.Above-mentioned the 1st embodiment completes the loading down maneuver of loading stage 4 with 1 telescopic cylinder 51, but if the large-scale transport trolley that needs large output and space to allow also can configure 2 above telescopic cylinders 51 side by side.
In addition, as tilting action device, if use guide tracked structure, compare with the structure of link-type, can manufacture simply send as an envoy to tilting rack 3 smoothly (roughly constant speed ground) do the required structure of tilting action.
In addition, for loading stage 4 is moved forward and backward, use times speed variator A can make loading stage 4 move with the amount of 2 times of the strokes of telescopic cylinder 51, therefore with the car transporter that cylinder directly makes loading stage move forward and backward, compare, can fulfil assignment at short notice, and can guarantee fully to make loading stage to drop to the required loading stage amount of movement in approximate horizontal position of Near Ground.
［ the 2nd embodiment shown in Fig. 9～Figure 11 ］
The corresponding technical solution of the present invention 3 of the 2nd embodiment shown in Fig. 9～Figure 11, when loading stage 4 rearward moves and does tilting action, can make rearward end (support foot 34) ground connection of tilting rack 3 as soon as possible.
The car transporter of the 2nd embodiment is by the structure of the support of the tilting rack 3 in above-mentioned the 1st embodiment 8 distortion, as the support 8 of tilting rack 3, be rearward end at auxiliary frame 12 supporting tilting rack 3 is set and make it before and after the roller 84 that moves freely.In the 2nd embodiment, between the rearward end of vehicle frame 11 and tilting rack 3, arrange and make tilting rack 3 move forward and backward the other telescopic cylinder 9 of use.Other structure of the 2nd embodiment of Fig. 9～Figure 11 is all identical with above-mentioned the 1st embodiment (Fig. 1～Fig. 8), can quote the explanation to the 1st embodiment.
The tilting rack 3 of the car transporter of the 2nd embodiment puts on roller 84 in the rearward end (support 8) of auxiliary frame 12, utilize special-purpose telescopic cylinder 9 can make tilting rack 3 with respect to auxiliary frame 12 and regulation length range in move forward and backward.And, by tilting rack 3 being moved forward and backward with this telescopic cylinder 9, can move forward and backward the tilting action center (using the part of roller 84 supportings of support 8) of adjusting this tilting rack 3.; once entering frame state from the loading stage of Fig. 9 makes to be exclusively used in tilting rack and moves forward and backward special-purpose telescopic cylinder 9 and extend; tilting rack 3 just rearward moves by its elongation, and now tilting rack 3 is supported the 8(of portion roller 84) position of supporting is just according to its mobile length and be displaced to front portion one side of tilting rack 3 rearward.Now, from the support 8 of tilting rack 3 till the distance of tilting rack rear end (support foot 34) is just elongated.
And, after the bearing position that makes as described above tilting rack 3 rearward moves, once main telescopic cylinder 51 is extended, tilting rack 3 is just centered by support 8 and gradually recede, as shown in figure 11, support foot 34 ground connection, and because of tilting rack 3 side shifting rearward, therefore correspondingly, till the time shorten of support foot 34 ground connection.That is, tilting rack 3 angle of inclination till 34 ground connection from flat-hand position to support foot is less than the situation shown in Fig. 7 and Fig. 8 (the 1st embodiment), thereby correspondingly, till the time shorten of support foot 34 ground connection.
To be by the way, once enter frame state from loading stage, telescopic cylinder 51 is extended gradually, loading stage 4 rearward moves, the load that makes to be thus applied to rear one side of tilting rack 3 increases gradually, till support foot 34 ground connection of tilting rack 3, the load (upper lifting force) applying with the chimeric roller 55 of guide rail 2 is increased gradually.And this load being applied on this roller 55 is that the time is shorter and load is the smaller the better.In the moment of support foot 34 ground connection, this support foot 34 and support 8 can bear the load being applied on tilting rack 3, and the load being therefore applied on roller 55 does not almost have.
And, in the 2nd embodiment, once make as described above telescopic cylinder 51 extend under the state that tilting rack 3 is rearward staggered with respect to support 8, support foot 34 just can be than the 1st embodiment ground connection earlier, therefore not only can shorten on above-mentioned roller 55 and execute the loaded time, can also alleviate the load that this roller 55 is applied.
