[0026] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0027] The embodiment of the present application provides a shuttle vehicle system with a maintenance device, which comprises: A first track 1 extends along a length direction A, and the first track 1 comprises at least one notch section 1a, An inspection track 2 extends along the length direction A and is arranged at one side of the first track 1, A second track 3 extends along the width direction B, one end of the second track 3 is arranged at the gap section la of the first track 1, and the other end is arranged at one end of the inspection track 2, A shuttle vehicle 4, the shuttle vehicle 4 comprises: A shuttle vehicle body 41, A movable track 43 is arranged at the bottom of the shuttle vehicle body 41, and the track surface of the movable track 43 is flush with the track surface of the first track 1 and the track surface of the inspection track 2; A first roller assembly 42 is arranged on the shuttle vehicle body 41 and can move along the first track 1 or the movable track 43; A second roller assembly 44 is arranged on the movable track 43; A driving assembly 45 is arranged on the shuttle vehicle body 41, When no inspection is required, the movable track 43 is arranged at the gap section la, and the first roller assembly 42 can drive the shuttle vehicle body 41 to roll along the first track 1 and the movable track 43; When inspection is required, the second roller assembly 44 can drive the movable track 43 and the shuttle vehicle body 41 to move along the second track 3 and reach the inspection track 2.
[0028] In a specific embodiment, as shown in Figure 1 and Figure 2 The first track 1 and the inspection track 2 extend from left to right, the inspection track 2 is arranged at one side of the first track 1, and the second track 3 extends from top to bottom, the upper end is arranged at the gap section la of the first track 1, and the lower end is arranged at the left end of the inspection track 2.
[0029] When no inspection is required, the movable track 43 is arranged at the gap section la, and the shuttle vehicle 4 can move left or right on the first track 1 and the movable track 43.
[0030] When maintenance is needed, the shuttle vehicle 4 moves to the gap section la of the first track 1, and then the second roller assembly 44 rolls on the second track 3, that is, the movable track 43 moves along the second track 3, and moves the shuttle vehicle body 41 from the gap section la of the first track 1 downward to the second track 3, and stops at the left end of the maintenance track 2. Since the track surface of the movable track 43 is flush with the track surface of the first track 1 and the track surface of the maintenance track 2, the shuttle vehicle 4 on the movable track 43 moves from the track surface of the movable track 43 to the maintenance track 2 for subsequent maintenance. This structure is simple, and when maintenance is needed, the shuttle vehicle 4 can be quickly moved to the maintenance track 2.
[0031] In the present application, a plurality of gap sections la can be provided on the first track 1, for example, three gap sections la are provided on the first track 1, and the second track 3 can be provided at any of the gap sections la. At the same time, a plurality of maintenance tracks 2 can also be provided to facilitate the simultaneous maintenance of a plurality of shuttle vehicles 4.
[0032] Further, the shuttle vehicle body 41 comprises: a bottom frame 411 in the shape of a rectangle, the bottom frame 411 comprising long plates 411a and wide plates 411b arranged alternately and fixedly connected in sequence, the long plates 411a extending along the length direction A, the wide plates 411b extending along the width direction B, the first roller assembly 42 being fixedly arranged on the long plates 411a, and the movable track 43 being fixedly arranged on the bottom side of the long plates 411a, a chain machine assembly 412 extending along the width direction B, the chain machine assembly 412 being used for placing a tray; two first support rods 413 extending along the height direction C, one end of each first support rod 413 being fixedly connected with the long plate 411a, and the other end being fixedly connected with the chain machine assembly 412; a detection frame 414 comprising at least one U-shaped frame, the opening of the U-shaped frame being fixedly connected with the long plate 411a, the detection frame 414 being used for detecting the size of goods; In a specific embodiment, as shown in Figure 4 、 Figure 5 、 Figure 6 The long plates 411a extend from left to right, and the wide plates 411b extend from top to bottom, the long plates 411a and the wide plates 411b are alternately fixedly connected and combined into the bottom frame 411, which is conducive to keeping the shuttle vehicle 4 stable during operation. The bottom of the two long plates 411a of the bottom frame 411 is provided with the movable track 43.
[0033] Since the first roller assembly 42 is fixedly arranged on the long plate 411a, the first roller assembly 42 can drive the long plate 411a to move on the first track 1, so that the first roller assembly 42 drives the bottom frame 411 to move in the left-right direction, i.e., drives the shuttle vehicle 4 to move on the first track 1.
[0034] By fixedly connecting the first supporting rod with the chain machine assembly 412 and the long plate 411a, the chain machine assembly 412 can be stably supported. The upper portion of the shuttle vehicle body 41 is further provided with the detection frame 414. When a pallet loaded with goods is placed on the chain machine assembly 412 above the shuttle vehicle body 41, the pallet will pass through the detection frame 414. Since the opening of the U-shaped frame faces downward and is fixedly connected with the long plate 411a, the U-shaped frame can quickly detect the width and height of the goods on the pallet, so that the goods exceeding the detection frame 414 can be prevented from being arranged on the shuttle vehicle body 41.
[0035] In operation, the pallet loaded with goods is placed on the chain machine assembly 412 through the detection frame 414, and the driving assembly 45 is started. The driving assembly 45 drives the first roller assembly 42 to rotate, and then the first roller assembly 42 drives the shuttle vehicle body 41 to move in the left-right direction on the first track 1, and sends the goods on the chain machine assembly 412 to a target position. The structure is simple, reasonable in design, and can quickly detect the size of the goods.
[0036] The first roller assembly 42 is fixedly arranged on the long plate 411a. Specifically, the driving assembly 45 comprises a first driving motor 451, which is arranged inside the bottom frame 411. The first roller assembly 42 comprises: A first driving shaft 421 extends in the width direction B. Two ends of the first driving shaft 421 are fixedly sleeved with first driving wheels 422. One first driving wheel 422 is rotatably connected to one end of one long plate 411a through a bearing with a seat, and the other first driving wheel 422 is rotatably connected to one end of the other long plate 411a through another bearing with a seat. The first driving shaft 421 is connected with the first driving motor 451, and the first driving motor 451 can drive the first driving shaft 421 to rotate. The other end of any long plate 411a is connected with a first driven wheel 423 through a bearing with a seat.
[0037] In a specific embodiment, as shown in Figure 4As shown, the first driving motor 451 can drive the first driving axle 421 to rotate, and since the first driving axle 421 has the first driving wheels 422 sleeved on both ends, the first driving wheels 422 can be driven to rotate, and since the first driving wheels 422 are connected to one end of the long plate 411a through the belt bearing, the long plate 411a is driven to move, i.e. the shuttle vehicle body 41 is driven to move, and since the other end of the long plate 411a is also provided with the first driven wheels 423, when the long plate 411a or the shuttle vehicle body 41 moves, the first driven wheels 423 can be driven to rotate, and the structure is simple and reasonable.
[0038] Further, the driving assembly 45 comprises a second driving motor 452, which is arranged inside the bottom frame 411. The chain machine assembly 412 comprises: Two mounting seats 412a, any of which extends along the width direction B and is fixedly connected to the first support rod 413 on the long plate 411a, and both ends of any of the mounting seats 412a are provided with second driven wheels 412b; A second driving axle 412c extending along the length direction A, both ends of the second driving axle 412c are sleeved with second driving wheels 412d, one of the second driving wheels 412d is rotatably connected to one of the mounting seats 412a, and the other second driving wheel 412d is rotatably connected to the other mounting seat 412a, the second driving axle 412c is connected to the second driving motor 452, and the second driving motor 452 can drive the second driving axle 412c to rotate; Two chains 412e, any of which is sleeved with one of the second driving wheels 412d and two second driven wheels 412b on one of the mounting seats 412a; Two groups of first guide roller assemblies, any of the first guide roller assemblies comprises two first guide rollers 412f, and the two first guide rollers 412f are rotatably connected to one of the mounting seats 412a, one of the first guide rollers 412f is arranged between the second driving wheel 412d and one of the second driven wheels 412b, and the other first guide roller 412f is arranged between the second driving wheel 412d and the other second driven wheel 412b; the chain 412e passes through the first guide roller 412f.
[0039] As Figure 5 , Figure 6 , Figure 7As shown, the second drive motor 452 can drive the second drive wheel shaft 412c to rotate. Since the second drive wheel 412d is sleeved at the end of the second drive wheel shaft 412c, the second drive wheel shaft 412c can drive the second drive wheel 412d to rotate. Since the chain 412e is sleeved on the second drive wheel 412d and the second driven wheel 412b, the second drive wheel 412d can drive the chain 412e to move and drive the second driven wheel 412b to rotate. When it is necessary to transport goods, the pallet with goods is moved through the chain 412e and placed on the shuttle car 4.
[0040] The chain 412e passes over the first guide wheel 412f. It is understood that the first guide wheel 412f helps adjust the tension of the chain 412e, preventing it from detaching from the second drive wheel 412d or the second driven wheel 412b, thus improving the stability and safety of the chain 412e's operation. During operation, the second drive motor 452 drives the second drive wheel 412d to rotate, which in turn moves the chain 412e. The chain 412e then causes the first guide wheel 412f and the second driven wheel 412b to rotate, facilitating the movement of the pallet onto the shuttle 4.
[0041] Furthermore, the shuttle 4 also includes: The edge-stop assembly 46 includes two edges, which extend along the width direction B and are spaced apart along the length direction A. Each edge is located on the side of the mounting base 412a opposite to the other mounting base 412a.
[0042] The sealing plate 47 extends along the width direction B and is fixedly mounted on the long plate 411a; Two second support rods 48 extend along the height direction C and are disposed between the two first support rods 413. One end of the second support rod 48 is fixedly connected to the long plate 411a and the other end is fixedly connected to the sealing plate 47.
[0043] like Figure 6 As shown, two guard edges are provided on the outside of the mounting base 412a in the two chain machine components 412, which can limit the pallet and goods on the chain 412e, prevent the pallet or goods from slipping off the chain 412e, and improve the safety of the shuttle car 4 during operation.
[0044] The second support rod 48 is fixedly connected with the sealing plate 47 and the long plate 411a, thereby stably supporting the sealing plate 47. The sealing plate 47 is used for supporting goods or workers, and can prevent dust or sundries from falling into the bottom frame 411. The chain assembly 412 is used for moving a tray loaded with goods to the shuttle vehicle 4.
[0045] Since the sealing plate 47 and the chain assembly 412 extend along the width direction B and are fixedly connected above the long plate 411a, and since the opening of the detection frame 414 is fixedly connected with the long plate 411a, when goods are placed on the sealing plate 47 or a tray is placed on the chain assembly 412, the opening of the detection frame 414 can quickly detect the goods or the goods on the tray, thereby limiting the height or width.
[0046] It should be noted that the number of the first support rod and the second support rod 48 is not limited to two. The more the number of the first support rod and the second support rod 48, the more stable the position and structure of the sealing plate 47 and the chain assembly 412. The first support rod and the second support rod 48 can be fixedly connected with the long plate 411a and the sealing plate 47 by welding or bolt connection. This structure is simple, reasonable in design, and stable in structure.
[0047] The number of the detection frame 414 is not limited in the present application. In a specific embodiment, the detection frame 414 includes: two parallelly arranged U-shaped frames, one opening of the U-shaped frame is fixedly connected with the long plate 411a, and the other opening of the U-shaped frame is fixedly connected with another long plate 411a; at least one frame connecting rod, one end of the frame connecting rod is fixedly connected with one U-shaped frame, and the other end of the frame connecting rod is fixedly connected with another U-shaped frame; a plurality of photoelectric sensors 414a for detecting whether the goods are skewed.
[0048] The number and position of the frame connecting rod are not limited. In a specific embodiment, as shown in Figure 3 four frame connecting rods are arranged on the shuttle vehicle 4, two frame connecting rods are arranged along the height direction and are fixedly connected with two vertical rods on one side of two U-shaped frames, and the other two frame connecting rods are also arranged along the height direction and are fixedly connected with two vertical rods on the other side of two U-shaped frames. This structure is simple and stable.
[0049] The photoelectric sensor 414a can detect whether the goods are skewed, avoid the goods from falling off during transportation, and ensure the safety of the shuttle vehicle 4. The U-shaped frame can quickly detect whether the length and height of the goods meet the requirements, and the detection is convenient and fast.
[0050] Further, the movable track 43 comprises: two movable track bodies 431, the two movable track bodies 431 are arranged side by side and extend along the length direction A, and any movable track body 431 is fixedly connected to the bottom of a long plate 411a, at least one track connecting rod 432, one end of any track connecting rod 432 is fixedly connected to one movable track body 431, and the other end is fixedly connected to another movable track body 431; a speed reduction piece extending along the length direction A and fixedly connected to the track connecting rod 432, one end of the speed reduction piece is located at one end of the movable track 43 away from the maintenance track 2; The shuttle vehicle 4 comprises at least one set of the second roller assembly 44, any set of the second roller assembly 44 comprises two second rollers, one of which is arranged on one side of one movable track body 431, and the other is arranged on one side of another movable track body 431, and the second rollers can roll along the second track 3.
[0051] In a specific embodiment, as shown in Figure 8 The movable track 43 comprises two movable track bodies 431 arranged side by side from left to right, the upper end of the track connecting rod 432 is fixedly connected to the upper movable track body 431, and the lower end of the track connecting rod 432 is fixedly connected to the lower movable track body 431. The track connecting rod 432 is conducive to supporting and controlling the parallelism of the two movable track bodies 431.
[0052] The number and position of the track connecting rod 432 are not limited. In a specific embodiment, as shown in Figure 8 The movable track 43 comprises four connecting rods arranged at intervals along the length direction A.
[0053] In one embodiment, the deceleration plate (not shown) extends from left to right, and the left end of the deceleration plate is located at the left end of the movable track 43. Before maintenance, the shuttle 4 moves on the first track 1, and the movable track 43 is located at the gap section 1a of the first track 1. When maintenance is required, the shuttle 4 moves to the movable track 43 at the gap section 1a. Since the left end of the deceleration plate is aligned with the left end of the movable track 43, when the shuttle 4 moves to the gap section 1a, the shuttle 4 can sense the deceleration plate on the movable track 43. The shuttle 4 starts to brake and immediately decelerates until it stops. At this time, the shuttle 4 can stop on the movable track 43, and then the movable track 43 drives the shuttle 4 to move along the second track 3 until the maintenance track 2.
[0054] Both sides of the two movable track bodies 431 are equipped with second rollers. Since the second rollers can roll along the second track 3, they can drive the movable track 43 to move along the second track 3, thereby enabling the shuttle 4 to move on the second track 3. The structure is simple and the design is reasonable. The number of second roller assemblies 44 is unlimited. As shown in the figure, the shuttle 4 includes three sets of second roller assemblies 44, that is, three second rollers are provided on the side of any movable track body 431. This structure facilitates the smooth operation of the shuttle 4 to the maintenance point.
[0055] It should be noted that the number of the second rollers and the number of the second tracks 3 should be the same. In one embodiment, there are three second tracks 3, and the positions of the three second roller assemblies 44 correspond one-to-one with the positions of the three second tracks 3. Any second roller assembly 44 can roll on a second track 3.
[0056] Furthermore, the movable track 43 also includes: At least one set of locking components 431, said locking components 431 including: A locking rod 431a extends along the width direction B. One end of the locking rod 431a is fixedly connected to one of the movable track bodies 431, and the other end is fixedly connected to another of the movable track bodies 431.

The L-shaped locking member 431b includes a horizontal piece and a vertical piece that are fixedly connected. The vertical piece is provided with at least one second locking hole. The number and position of the second locking holes correspond one-to-one with the number and position of the first locking holes. The horizontal piece is provided with a third locking hole. Locking bolt 431c is used to fix the first locking hole and the second locking hole; A fixing bolt can pass through the third locking hole and fix the cross piece to the ground.
[0057] The number and position of the locking components 431 described in this application are not limited. In a specific embodiment, such as... Figure 9 As shown, the movable track 43 is provided with two sets of locking components 431. The two sets of locking components 431 are arranged at intervals along the length direction A. The end of any locking rod 431a is provided with the first locking hole, and the end of each rod is provided with the locking member 431b.
[0058] It should be noted that when no maintenance is required, the movable track 43 is located at the notch section 1a of the first track 1, as shown in the figure. The fixing bolt can be an expansion bolt. By passing the fixing bolt through the third locking hole and fixing it to the ground, the cross piece of the locking member 431b can be fixed to the ground, and thus the position of the locking member 431b remains fixed relative to the ground.
[0059] Since the locking bolt 431c is fixedly connected to the first locking hole on the locking rod 431a and the second locking hole on the vertical piece, this structure can fix the locking rod 431a to the locking member 431b. Furthermore, since the upper end of the locking rod 431a is fixedly connected to the upper row of movable track bodies 431 and the lower end is fixedly connected to the lower row of movable track bodies 431, the movable track 43 can remain fixed relative to the ground. When the shuttle car 4 moves from the first track 1 to the movable track 43 on the notch section 1a, it can prevent the movable track 43 from shaking, ensuring smooth operation of the shuttle car 4.
[0060] Furthermore, the shuttle 4 also includes: At least one set of second guide wheel assemblies 49 are disposed on the long plate 411a, and any set of second guide wheel assemblies 49 includes: The guide wheel seat is fixedly connected to the long plate 411a; Two second guide wheels are fixedly mounted on the guide wheel seat. One second guide wheel is located on one side of the long plate 411a and can roll along one side of the first track 1 or the movable track body. The other second guide wheel is located on the other side of the long plate 411a and can roll along the other side of the first track 1 or the movable track body.
[0061] like Figure 4As shown, the two second guide wheels are located on both sides of the long plate 411a and can roll along the first track 1 or the sides of the movable track body. Thus, when the shuttle car 4 moves, the two second guide wheels can play a limiting role, preventing the shuttle car body 41 from derailing and improving the safety of the shuttle car 4 operation.
[0062] Furthermore, a first limiting member 21 is provided at the end of the maintenance track 2 away from the second track 3; And / or, the second track 3 is provided with a second limiting member 31 at the end away from the first track 1.
[0063] In a specific embodiment, such as Figure 1 As shown, the right end of each maintenance track 2 is provided with the first limiting member 21. When maintenance is required, when the shuttle car 4 on the movable track 43 moves to the maintenance track 2, the first limiting member 21 can limit the position of the shuttle car 4 on the maintenance track 2 and prevent the shuttle car 4 from derailing on the maintenance track 2. Similarly, the second limiting member 31 at the lower end of the second track 3 can prevent the movable track 43 from derailing on the second track 3.
[0064] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
