Still,, come service load transportation unit 100 and load carrier unit 200 as follows for further specifying the process of fetching with reference to Figure 10.As described at Fig. 8 and 9, an empty load carrier unit 200 is connected on the load transportation unit 100 fastenedly.After securely being connected in idling carrying carrier unit 200 on the load transportation unit 100, the operator shifts to fork lift 410 with the structure 300 that is connected.During near fork lift 410, the correspondence on the directing pin 330 aiming fork lifts 410 receives structure 430 in the structure that is connected.In alignment procedures, the operator locatees structure 300 that is connected and the height of regulating the structure 300 that is connected by handle 150 by pilot wheel 140.As discussed previously, increase by vertical twitch handle 150 from ground-surface height, and by discharging it and highly keep mechanism and reduce height via promoting shift unit 170.Directing pin 330 and the complimentary engagement that receives between the structure 430 guarantee that automatically the structure 300 that is connected is positioned in the predetermined battery switch of fork lift 410.According to directing pin 330 during near predetermined battery exchange height and position, the hook 270 of load carrier unit 200 also starts and finishes and the engaging of the hook joint unit 420 of fork lift 410 in the structure 300 that is connected.As shown in figure 10, when the predetermined battery of structure 300 arrival next-door neighbour fork lifts 410 sidepieces that connected exchanges height and position, finished the suitable joint between hook 270 and the hook joint unit 420.At the predetermined battery switch, the operator applies via interruption 180 and parks interruption with fastening safe battery swap position.
According to the present invention, in safety battery swap position, operation is fetched to conclude the accident free battery by the add-on security mechanism that the operator controls first preferred embodiment.At the beginning, load control device rotatable grip 320 rotates in the clockwise direction so that load baffle plate 310 is placed and leaves load support surface 200S, and battery pack M ' is got back to from fork lift 410 on the load support surface 200S that fetches position M ' shown in dotted line then.In case confirmed the suitable position M ' that fetches, the operator is fastened on battery pack M ' on the load carrier unit 200 by following: rotate rotatable grip 320 in the counterclockwise direction so that load baffle plate 310 is placed on the front end of load support surface 200S so that stop moving forward of battery pack M '.Confirmed fastening battery pack M ' afterwards the operator, he or she now before the structure 300 that will be connected moves to desired location the hook joint unit 420 from fork lift 410 break away from hooks 270.It is to finish by removable lever is pulled to handle 150 that hook breaks away from.Above-described security feature mechanism will further describe in following detailed description to preferred embodiment.
With reference now to Figure 11,, some mechanical parts of the hook joint system during transparent view has been isolated according to a first advantageous embodiment of the invention.At as described in Figure 10, hook 270 is positioned at predetermined engage position or predetermined disengaging configuration via removable control lever 290 as above.When connection control device 400 was in engagement state, shown in solid line, removable control lever 290 was in control engage position 292A.In other words, when the removable control lever 290 of connection control device 400 was in engagement state, shown in solid line, hook 270 was positioned in predetermined engage position.Generally speaking, hook 270 is positioned at engage position by the propelling that spring 272 causes.
Still with reference to Figure 11, on the other hand, when the operator was pulled to position 290C with removable control lever 290 as shown by arrows, when connection control device 400 was transformed into disengaged position, removable control lever 290 was positioned at by the control disengaging configuration shown in the dotted line.Because pulling action, removable control lever 290 rotates in a counter-clockwise direction the first chain extension bar 294 as shown by arrows.The rotation of the first chain extension bar 294 as shown by arrows first link arm 295 and the second chain extension bar 296 are pushed to forwards to.At last, moving forward of the second chain extension bar 296 makes second link arm 297 and the propelling mutually on the contrary as shown by arrows in the counterclockwise direction rotation of the 3rd chain extension bar 298 with spring 272.Therefore, when the removable control lever 290 of connection control device 400 was in engagement state, hook 270 was as being scheduled to disengaging configuration 270A to be placed in shown in dotted line and the corresponding arrow.
With reference now to Figure 12,, other mechanical part of the hook joint system during transparent view has been isolated according to a first advantageous embodiment of the invention.At shown in Figure 11, hook 270 is placed in engage position or as the disengaging configuration 270A shown in broken lines shown in solid line as above.Generally speaking, as described at Figure 11, hook 270 places engagement state by the propelling that spring 272 is caused.The operator handles load carrier unit 200 with the joint of corresponding contained structure by directing pin 330 as shown by arrows towards assigned target position.Meanwhile, during near predetermined structure 410, hook 270 remains on predetermined engage position at hook 270.In case contact with the hook joint unit, rotate by operator's promotion that further moving forward of load carrier unit 200 made hook 270 because the weight of its sloping portion opposite with described propelling and hook 270 make progress and around the 3rd chain extension bar 298.Subsequently, the corresponding wall of the vertical part of hook 270 and hook joint unit 420 engages, thereby finishes correct location to described load carrier unit 200 with fastening means.
With reference now to Figure 13,, other mechanical part of the hook joint system during transparent view has been isolated according to a first advantageous embodiment of the invention.Particularly, described transparent view parts related that the disengaged position that is used to lock described connection control device is shown with removable control lever 290.Removable control lever 290 and the first chain extension bar 294 prevent that by link connecting panel or rotation plate 290D from captiveing joint.At as described in Figure 11, removable control lever 290 is drawn forward or backward so that the first chain extension bar 294 rotates via link connecting panel 290D as double-headed arrows as above.The most described hook of the rotation of the first chain extension bar 294 is placed to and is in desired location.Depend on and be used to locate the above-mentioned of described hook and move, removable control lever 290 also provides additional security feature during operation.
Still with reference to Figure 13, removable control lever 290 further comprises the optional feature that moves that is used to control removable control lever 290.Holding portion 293 is contained in vertical part 290A in its inner space at near-end.Vertically the far-end 290E of part 290A extends outside the far-end of holding portion 293.Vertically part 290A is removable in the holding portion 290B of removable control lever 290.Vertically part 290A further comprises position pin 290B, and it is fixed on vertical part 290A and outstanding from the surface of vertical part 290A.Holding portion 293 also further comprises short groove 293A and elongated slot 293B, is used to accept position pin 290B.Short groove 293A and elongated slot 293B all start from the edge of near-end of holding portion 293, but elongated slot 293B further extends to such an extent that exceed short groove 293A downwards.At the position 292A shown in solid line, rotatable button 292 is oriented to make position pin 290B to be accepted by short groove 293A.At position 292B shown in dotted line, rotatable button 292 is oriented to make position pin 290B to be accepted by elongated slot 293B.Pin 290B in position has prevented to be further rotated to such an extent that exceed certain point by pin baffle plate 293C.Like this, the rotatable button 292 of removable control lever 290 can be as double-headed arrows along approximate 90 degree of the surface rotation vertical with the vertical component 290A of removable control lever 290.
At position pin 292B, position pin 90B is accepted by elongated slot 293B, and removable control lever 290 further moves down by following mechanism.Near far-end 290E, stopper pin 293H is positioned on the vertical part 290A.Spring 293F and a pair of packing ring 293E, 293G are placed on the vertical part 290A between the far-end of stopper pin 293H and holding portion 293.Because spring 293F pushes packing ring 293E and 293G open respectively to the far-end and the stopper pin 293H of holding portion 293, when position pin 290B was accepted by elongated slot 293B, far-end 290E was pushed into shown in dotted line and shift to extendible portion.Therefore, when position pin 290B was accepted by elongated slot 293B, the rotatable button 292 of removable lever 290 was moved down into position 292C automatically from position 292B.
On the other hand, as the arrow that makes progress shown in, opposite when the propelling that is caused with spring 293F, when position 292C moved, vertically the mobile 290E of part 290A retracted from above-mentioned extended position by following mechanism movable knob 292 by the operator.When vertically part 290A was pulled, stopper pin 293H upwards promoted lower gasket 293G with compression spring 293F.Subsequently, in the counterclockwise direction after position 292B rotates to position 292A, position pin 290B is accepted by short groove 293BA at rotatable button 292.Therefore, mobile 290E maintains the retrieving position shown in solid line and spring 293F remains on compressive state.
With reference now to Figure 14,, lateral plan illustrates the position relation in some parts of isolating of the safety gear in first preferred embodiment of the present invention.This lateral plan through isolating is to see from load carrier unit 200 sides shown in the arrow Fig. 7.At as described in Figure 13, rotatable button 292 rotates between two position 292A and the 292C as, and rotatable button 292 also changes its vertical position between two position 292A and 292C.At position 292C, rotatable button 292 is in disengaged position so that described hook is placed predetermined disengaging configuration.The rotatable button 292 at 292C place, position reduces by the propelling from spring 293F shown in downward arrow.The spring 293F that expands forces packing ring 293E and 293G to divide the stopper pin 293H that opens with on the vertical part 290A of promotion on the downward direction.As a result, vertically the far-end 290E of part 290A engages with bore hole (bore) 153A of base plate 153.Like this, when removable control lever 290 was in disengaged position, above engaging gear was locked in this position 292C so that hook is maintained disengaging configuration with rotatable button 292.By hook 270 is maintained predetermined disengaging configuration, when the operator moved apart described predetermined structure with the load carrier unit 200 on the load transportation unit 100, this lockout mechanism provided security feature.
On the other hand, at position 292A, rotatable button 292 is in engagement state shown in dotted line.When rotatable button 292 was rotated and retracts towards handle 150, removable control lever 290 made the first chain extension bar 294 as shown by arrows via link connecting panel 290D left-hand revolution.Meanwhile, at position 292A, rotatable button 292 is raise by the relative spring 293F of operator.As a result, vertically the far-end 290E of part 290A breaks away from bore hole 153A from base plate 153 own.Like this, when removable control lever 290 was in engagement state, the rotatable button 292 that is in position 292A maintained predetermined engage position with described hook.
Still with reference to Figure 14, the position of other safety gear during described lateral plan also illustrates according to a first advantageous embodiment of the invention concerns.Generally speaking, load control device rotatable grip 320 control load lockout mechanism or unit are as described at Fig. 5,6,7 and 10.The rotatable grip assembly 320 of load control device be provided with adjacent to the removable control lever 290 of hook joint control setup and with load control device mutual action mechanically.Rotatable grip assembly 320 further comprises load control device button 320A, and it is attached to spring 320C and safety pin 320B.Rotatable grip assembly 320 is supported by mounting bracket 320D by bore hole 320E, and mounting bracket 320D is attached to the rotatable arm 320G of load control device.Rotatable arm 320G of load control device and rotatable grip assembly 320 are designed to lock with control load around 322 rotations of chain extension bar.
Figure 14 also illustrates near the security feature that is provided for load-lock mechanism in a preferred embodiment according to the present invention.Safety pin 320B extends through the bore hole 320F of the rotatable arm 320G of load control device and also extends outside the part nearby of the link connecting panel 290D shown in solid line.When attempting rotatable arm 320G of rotary load control setup and rotatable grip assembly 320, the operator safety knobs 320A must be pulled away from rotatable arm 320G so that safety pin 320B removes (clear) link connecting panel 290D.Distance between link connecting panel 290D and the rotatable arm 320G of load control device depends on the position of removable control lever 290 and changes.Position relation between safety pin 320B and the link connecting panel 290D will further be described in detail at Figure 15,16 and 18.
With reference now to Figure 15,, during having isolated according to a first advantageous embodiment of the invention, transparent view is used for the parts of the previous described safety gear of load-lock control and hook joint control setup.Before removable control lever 290 is positioned at rotatable grip assembly 320.As at as described in Figure 11,12,13 and 14, the operator forward with to the removable control lever 290 of backward shift to control the position of hook 270 via link 294 to 298.As also describing, the rotatable grip assembly 320 of load control device 500 be provided with adjacent to the removable lever 290 of the load control device of hook joint control setup 400 and with connection control device 400 mutual action mechanically.When load control device 500 was in the predetermined load lock-out state, the rotatable load-lock handle 320 of load control device 500 was in the predetermined latched position 320A shown in solid line.In other words, when the rotatable load-lock handle 320 of load control device 500 was in the load-lock state, load baffle plate 310 was placed on predetermined load latched position shown in solid line with load as described in fastening.
Still with reference to Figure 15, on the other hand, when the operator rotates to position 320A ' with rotatable load-lock handle 320 as shown by arrows, when load control device 500 was transformed into predetermined load and unties state, rotatable load-lock handle 320 was positioned at predetermined load shown in dotted line and separates open position 320A '.Rotate to position of rotation 320A ' as shown by arrows in a clockwise direction at rotatable load-lock handle 320, load baffle plate 310 is placed on predetermined load shown in dotted line and separates open position 310A.When rotatable button 320A arrived position of rotation 320A ', displacement baffle plate shown in dotted line or disengaging baffle plate 340 also were placed on stand up position 340A adjacent to link connecting panel 290D after removable control lever 290.As the part of additional security feature, the above-mentioned rotation of rotatable load-lock handle assembly 320 depends on the position of the rotatable lever 290 of connection control device, as will be at Figure 16,17 and 18 described.
With reference now to Figure 16,, load control device and the direct interactional security feature of connection control device during lateral plan illustrates according to a first advantageous embodiment of the invention.This lateral plan through isolating is to see from load carrier unit 200 sides shown in the arrow Fig. 7.It is because provide description at Figure 14 that some parts does not come into question.As described at Figure 14, the rotatable button 292 at position 292A place is in engagement state, and vertically the far-end 290E of part 290A breaks away from bore hole 153A from base plate 153 own.When the hook joint control setup was in engagement state, assumed load carrier unit 200 securely engaged with predetermined structure so that load is delivered to described predetermined structure or fetches load from described predetermined structure.In other words, when the rotatable button 292 of connection control device during at position 292A, the rotatable grip assembly 320 of load control device is rotatable.Based on above supposition, the permission operator unties the load baffle plate 310 on the load carrier unit 200, as described at Figure 10.
Still with reference to Figure 16, further at describing the security feature related according to a first advantageous embodiment of the invention with rotatable load-lock handle assembly 320.No matter above supposition, when in fact the operator attempts rotating rotatable load-lock handle assembly 320, by forcing the operator away from link connecting panel 290D load control device button 320A to be pulled to retrieving position 320A ' as described in arrow, first preferred embodiment provides additional security feature.When load control device button 320A was recovered to retrieving position 320A ', spring 320C was compressed with respect to support 320D, and safety pin 320B also via bore hole 320F with the equidirectional shown in the arrow on move.As above mobile result, the terminating end 320B-T of safety pin 320B arrives its retrieving position 320B-T ' shown in dotted line.At retrieving position 320B-T ', during as shown by arrows around chain extension bar 322 rotation, safety pin 320B removes link connecting panel 290D at rotatable load-lock handle assembly 320.Like this, regardless of the supposition to the hook joint state, described supplementary features force the operator to conclude that by regain load control device button 320A in the rotatable load-lock handle assembly 320 of rotation safety is to untie load baffle plate 310.
With reference now to Figure 17,, direct other interactional security feature of load control device and connection control device during lateral plan illustrates according to a first advantageous embodiment of the invention.This lateral plan through isolating is to see from load carrier unit 200 sides shown in the arrow Fig. 7.It is because provide description at Figure 14 that some parts does not come into question.As described at Figure 14, the rotatable button 292 at position 292A place is in engagement state, and vertically the far-end 290E of part 290A breaks away from bore hole 153A from base plate 153 own.When the hook joint control setup is in engagement state, allow the operator to rotate rotatable load-lock handle assembly 320, as discussing at Figure 16.Rotate to after predetermined load separates open position at rotatable load-lock handle assembly 320, described load control device is in disengaged position.Load stopper 310 is untied now so that load carrier unit 200 be sent or be got back to load can from load carrier unit 200, as discussing at Figure 10 and 15.
Still with reference to Figure 17, during the lateral plan through isolating is illustrated in according to a first advantageous embodiment of the invention with respect to the load control device that is in disengaged position of the connection control device that is in engagement state.Rotate to after predetermined load separates open position at rotatable load-lock handle assembly 320, displacement baffle plate 340 is placed on stand up position 340A adjacent to linking connecting panel 290D removable control lever 290 after.Separate open position at predetermined load, stand up position 340A stops removable control lever 290 rearward moving up.In other words, when described load control device is in disengaged position, prevented that the operator is displaced to disengaged position so that hook 270 is placed predetermined disengaging configuration with removable control lever 290.By preventing that the operator breaks away from hook 270 accidentally, this mechanism concludes the safety during load is sent or fetched automatically.
With reference now to Figure 18,, the direct other again mutual action security feature of load control device and connection control device during lateral plan illustrates according to a first advantageous embodiment of the invention.This lateral plan through isolating is to see from load carrier unit 200 sides shown in the arrow Fig. 7.It is because provide description at Figure 14 that some parts does not come into question.As before discussing at Figure 16, no matter to the supposition of hook joint, described supplementary features force the operator predeterminedly load control device button 320A to be recovered to retrieving position 320A ' when separating open position in that rotatable load-lock handle assembly 320 is rotated to.This security feature is further adjusted based on the position of the removable control lever 290 of connection control device, as with described here.
Still with reference to Figure 18, described lateral plan illustrates and is in disengaged position in a preferred embodiment according to the present invention to stop the connection control device of load control device.As discussed previously, rotatable button 292 rotates between two position 292A and the 292C.At position 292C, rotatable button 292 is in disengaged position so that described hook is placed predetermined disengaging configuration and lock by the propelling from spring 293F, thereby the far-end 290E of vertical part 290A is engaged with the bore hole 153A of base plate 163.At position 292C and since removable control lever 290 from forward position 292A be displaced to the back to position 292C with on direction as shown by arrows around link 294 rotations, reduce to the physical distance of rotatable grip arm 320G and removable control lever 290.
At described connection control device as with when being in engagement state shown in the solid line, when the operator attempts by load control device button 320A being recovered to the rotatable load-lock handle assembly 320 that retrieving position 320A ' comes the rotary load control setup, because the described distance that reduces, other again security feature has stopped described rotation.Although load control device button 320A is withdrawn into retrieving position 320A ', because the described distance that reduces, the terminating end 320B-T that is in the safety 320B of its retrieving position 320B-T ' still can not remove link connecting panel 290D.In other words, according to this security feature,, do not allow the operator to untie load unless described hook is in predetermined engage position.
With reference now to Figure 19 A and 19B,, diagram of circuit illustrates contained step in the preferred process of the load carrying device that the operations according to the instant invention safety strengthens.Action and step are to describe at according to a first advantageous embodiment of the invention parts, unit and mechanism.Like this, carry out reference at Fig. 5 to 18 to these parts in first preferred embodiment.In preferred process, for example the load carrying device that strengthens via as shown in figure 10 safety of the present invention such as the predetermined load M of battery and being delivered to such as the required destination structure of fork lift 410 or from it is fetched.
With reference now to Figure 19 A,, at step S1, the load carrying device that the operator will strengthen is safely shifted to intended destination.At step S2, the operator attempts engaging load carrier unit 200 and predetermined structure.At step S1 during near predetermined structure, the corresponding contained structure 430 on the directing pin 330 aiming fork lifts 410 is to attempt the suitable joint between hook 270 and the hook joint unit 420 as shown in Figure 10 at load transportation unit 100 and load carrier unit 200.At step S3, determine whether to complete successfully described suitable joint.If determine successfully to have finished joint between hook 270 and hook joint unit 420 at step S3, preferred process proceeds to step S5.On the other hand, if determine successfully not finish described joint, then conclude that at step S4 described connection control device is in engagement state at step S3.In other words, as described at Figure 11, in order successfully to infer hook joint, the removable control lever 290 of connection control device must be in engagement state.Then, preferred process is got back to step S2 and is proceeded to attempt with the joint that continues as previously discussed.
Still with reference to figure 19A, preferred process continues to finish according to all the other steps of the present invention.In case complete successfully hook joint, by the rotatable load-lock handle assembly 320 of rotary load control setup when load control device button 320A is recovered to retrieving position 320A ', the operator attempts untiing load at step S5.At this, untiing load is not to mean that load must be present in load and deliver among the surperficial 200S.On the contrary, same phrase is used to refer to that load baffle plate 310 delivers surperficial 200S from load and successfully discharges.If determine that at step S6 load control device is successfully placed load to untie state, preferred process proceeds to step S8.On the other hand, if determine that at step S6 load control device is not successfully placed load to untie state, preferred process proceeds to step S7, and here the operator concludes that connection control device is in engagement state.In other words, as described at Figure 18, if the removable control lever 290 of connection control device is in disengaging configuration, link connecting panel 290D stops rotatable load-lock handle assembly 320 to rotate to load to separate open position.After step S7, preferred process repeating step S5.
Confirming that hook 270 is engaged and load baffle plate 310 leaves after load delivers surperficial 200S, carrying out preplanned mission.At step S8, determine that preplanned mission is to send or fetch load.If determine that at step S8 preplanned mission is a delivery tasks, execution in step S9 is delivered between the predetermined battery of fork lift 410 so that load is delivered surperficial 200S from the battery of load carrier unit 200.On the other hand, if determine that at step S8 preplanned mission is the task of fetching, execution in step S10 is to deliver battery on the surperficial 200S from the load that gets back to load carrier unit 200 between the predetermined battery of fork lift 410.After having carried out preplanned mission, preferred process is prepared the disengaging shown in Figure 19 B now.
With reference now to Figure 19 B,, diagram of circuit illustrates the step after above-mentioned preplanned mission according to the present invention.Determine at step S11 whether preferred process has finished predetermined fetching or delivery tasks.If step S11 determines not finish preplanned mission as yet, then preferred process is waited at step S11.On the other hand, if finished preplanned mission, then preferred process proceeds to step S13.For example, in case that confirms the battery fetched suitably fetches position M ', then the operator is fastened on battery pack M on the load carrier unit 200 by following: rotate rotatable grip 320 in the counterclockwise direction so that load baffle plate 310 is in the front end of load support surface 200S so that stop travelling forward of battery pack M.
