When the carrying device moves to the intersection of the longitudinal rail and the transverse rail and needs to be reversed to the transverse rail to move, the lifting driving mechanism 120 can drive the transverse traveling wheel set 400 to descend through the lifting transmission mechanism 500. When the transverse traveling wheel set 400 descends to fall on the transverse rail, the elevation driving mechanism 120 drives the transverse traveling wheel set 400 to continue descending through the elevation transmission mechanism 500. In this process, the longitudinal running wheel set 300 may be jacked up to be higher than the lateral running wheel set 400. Thus, the longitudinal running wheel group 300 can be separated from the rail, preventing interference. At this time, the carrier apparatus can move on the transverse rails. On the contrary, when the handling apparatus moves to the intersection of the longitudinal rail and the transverse rail and needs to be reversed to the longitudinal rail to move, the lifting driving mechanism 120 may drive the transverse traveling wheel set 400 to ascend through the lifting transmission mechanism 500. The longitudinal running wheel set 300 may be relatively lowered, and when the longitudinal running wheel set 300 is lowered to fall on the longitudinal rail, the elevation driving mechanism 120 drives the lateral running wheel set 400 to continue to be raised through the elevation transmission mechanism 500. In this process, the lateral running wheel group 400 may be higher than the longitudinal running wheel group 300. In this way, the transverse running wheel set 400 can be disengaged from the rail, preventing interference. At this time, the carrier apparatus may move on the longitudinal rails.

Illustratively, the material offset sensors may include a first material offset sensor 941, a second material offset sensor 942, and a third material offset sensor 943. The first material off-load sensor 941 and the second material off-load sensor 942 may be disposed on one of a pair of outer side walls (e.g., the outer side wall of the first longitudinal side panel 621). A third material offset load sensor 943 may be disposed on the other of the pair of outer side walls (e.g., the outer side wall of the second longitudinal side plate 622). First material offset sensor 941 and third material offset sensor 943 are opposite in the transverse direction X-X. So configured, first material offset load sensor 941 and second material offset load sensor 942 can be used to detect if a material is offset in the longitudinal direction Y-Y. First material off-load sensor 941 and third material off-load sensor 943 may be used to detect if material is off-set in the lateral direction X-X. The first material off-load sensor 941, the second material off-load sensor 942, and the third material off-load sensor 943 may be used to detect whether a material is deflected in a horizontal direction.

The second sensor group may include a position sensor 930. The position sensor 930 may be used to detect the position of the handling apparatus. According to the result detected by the positioning sensor 930, it can be used for accurate positioning. The type of the position sensor 930 is not limited, and includes but is not limited to a barcode scanner and an image sensor. The detection direction of the position sensor 930 may be directed downward in the vertical direction of the conveyance apparatus. For example, different two-dimensional codes can be arranged at different positions on the carrying system. The handling apparatus can be precisely positioned by recognizing the two-dimensional code by the positioning sensor 930.

Illustratively, a bottom plate opening may be provided on the bottom plate 610 of the main body 600. The body 600 may also include a dam 690. The dam 690 may extend upward from the edge of the floor opening. The space enclosed by the dam 690 may be shaped like a frustum of a prism. Position sensor 930 may be positioned at the top of apron 690 with the detection direction down. By providing the dam 690, the detection range of the position sensor 930 is expanded. Also, the top of the dam 690 is small in size, facilitating sealing to prevent foreign substances such as dust from entering the inside of the main body 600.

Through setting up different sensors, can realize multiple functions such as location, keep away the barrier, detect the material. Therefore, accidents such as collision can be avoided, the safety is improved, and the movement of the carrying equipment can be planned more, so that the working efficiency is improved. So, haulage equipment's function is abundanter to be convenient for realize intelligent control. The user experience is better. The market competitiveness of the carrying equipment is better.

The carrying apparatus may further include a crane 140 provided on the main body 600. The longitudinal traveling wheel set 300 or the lateral traveling wheel set 400 may be provided on the crane 140. The elevation driving mechanism 120 may be connected to the elevation frame 140. The elevation driving mechanism 120 may drive the elevation frame 140 to ascend and descend through the elevation transmission mechanism 500 to drive the longitudinal traveling wheel set 300 or the transverse traveling wheel set 400 to ascend and descend. Specifically, the crane 140 is movable between a lifting position, an intermediate position, and a lowering position in the vertical direction. Exemplarily, taking the crane 140 connected to the transverse traveling wheel set 400 as an example, when the crane 140 is at the lifting position, the transverse traveling wheel set 400 may be higher than the longitudinal traveling wheel set 300; when the lifting frame 140 is in the middle position, the transverse traveling wheel set 400 and the longitudinal traveling wheel set 300 are in the same horizontal plane; when the crane 140 is in the lowered position, the transverse running wheel group 400 may be lower than the longitudinal running wheel group 300.

As shown in fig. 12, the second sensor group may further include a lifting position sensor. The lift position sensors may include a lift position sensor 961, a neutral position sensor 962, and a lower position sensor 963. The lift position sensor 961 may be used to detect whether the lift frame 140 is in the lift position. The neutral position sensor 962 may be used to detect whether the crane 140 is in the neutral position. The descending position sensor 963 may be used to detect whether the crane 140 is located at the descending position. The types of the lift position sensor 961, the neutral position sensor 962, and the down position sensor 963 are not limited, and include, but are not limited to, photoelectric sensors. Illustratively, the lift position sensor 961, the neutral position sensor 962, and the lower position sensor 963 may be U-shaped sensors. So set up, can detect crane 140's position, prevent that crane 140's position from taking place the deviation to cause dangerous accident to take place.

The handling device may also comprise, for example, a lifting plate (not shown). The lifting plate may be covered on the lifting frame 140. The lifting plate is movable with the crane 140 between a lifting position and a predetermined position. The predetermined position may be below the raised position and above the lowered position. The lifting plate may be supported on the main body 600 when it is in a predetermined position. The lifting plate may be located above the body 600. The lifting plate may be used to hold material. When the crane 140 is in the lifting position, the lifting plate can lift up the material placed on, for example, a bin, so that it can be transported. During the lowering of the crane 140, the lifting plate may be moved to a predetermined position. At this time, the lifting plate may fall over the main body 600.

The second sensor set may also include a lift plate position sensor 970. The lift plate position sensor 970 may be used to detect whether the lift plate is lowered to a predetermined position, thereby ensuring safety of operation. The type of the lift plate position sensor 970 is not limited, and includes, but is not limited to, a photoelectric sensor, etc. Illustratively, the lift plate position sensor 970 may be two proximity switches. The proximity switch may be of any configuration including, but not limited to, a cylindrical proximity switch. Two cylindrical proximity switches may be located on either side of the lifting plate, for example in the transverse direction X-X.

Illustratively, the longitudinal running wheel set 300 may include a first longitudinal running wheel set 310 and a second longitudinal running wheel set 320. The first longitudinal running wheel set 310 and the second longitudinal running wheel set 320 may be located at both sides of the handling apparatus. The first and second longitudinal running wheel groups 310 and 320 may be respectively provided on the opposite outer sidewalls of the body 600 in the transverse direction X-X. In other words, the first longitudinal running wheel group 310 and the second longitudinal running wheel group 320 may be disposed at the outer sides of the first longitudinal side plate 621 and the second longitudinal side plate 622, respectively.

The first and second longitudinal running wheel sets 310 and 320, respectively, may comprise a plurality of pairs of longitudinal running wheel pairs 330. Pairs of longitudinal running wheel pairs 330 may be spaced apart in the longitudinal direction Y-Y. Each longitudinal road pair 330 may include a pair of longitudinal road wheels. Guide wheels 370 may be disposed between adjacent longitudinal road wheels within each longitudinal road pair 330. The guide wheel 370 is rotatable along an axis extending in the vertical direction. The guide wheels 370 may roll along the inner side walls of the longitudinal rails as the handling apparatus moves on the longitudinal rails. When the handling apparatus is ready to move from the lateral rails to the longitudinal rails, if the body 600 is not aligned with the longitudinal rails, the body 600 may rub against the longitudinal rails, or even fail to move onto the longitudinal rails. By arranging the guide wheel 370, on one hand, the friction between the main body 600 and the inner side wall of the longitudinal rail can be avoided; on the other hand, the device can play a role in guiding and ensure that the carrying equipment moves onto the longitudinal rail smoothly. In addition, the guide wheels 370 can make full use of the distance between a pair of longitudinal road wheels, so that the carrying device is more compact in structure and small in size.

Illustratively, the longitudinal road wheels may be provided with rims 340. Specifically, the outermost longitudinal road wheels in the longitudinal direction Y-Y of the first longitudinal road wheel group 310 and/or the second longitudinal road wheel group 320 may be provided with a rim 340. The rim 340 may be coaxially connected to the end of the longitudinal road wheel on which it is located facing the outer side wall. The space surrounded by the outer side of the rim 340 may be frustoconical and have an increasing radius in a direction towards the outer side wall. The rim 340 may abut against the inner side wall of the longitudinal rail. By providing the rim 340, when the handling device moves on the longitudinal rail, the handling device can be prevented from being separated from the longitudinal rail, ensuring smooth movement.

For example, the first longitudinal running wheel group 310 and the second longitudinal running wheel group 320 may be respectively connected to both ends of the driving shaft 250. So configured, the travel driving mechanism 110 can drive the longitudinal travel wheels of the first longitudinal travel wheel set 310 and the longitudinal travel wheels of the second longitudinal travel wheel set 320 to roll along the longitudinal direction Y-Y. Thus, the number of the travel driving mechanisms 110 can be reduced, and the structure of the conveying apparatus can be made compact and the size thereof can be made small. And, the cost can also be reduced. And the longitudinal traveling wheels in the first longitudinal traveling wheel set 310 and the longitudinal traveling wheels in the second longitudinal traveling wheel set 320 can synchronously roll along the longitudinal direction Y-Y, so that the carrying equipment can stably move along the longitudinal direction Y-Y.

Illustratively, the travel drive mechanism 200 may include a first longitudinal drive assembly 210 and a second longitudinal drive assembly 220. The first longitudinal transmission assembly 210 and the second longitudinal transmission assembly 220 may be disposed on a circumferential side of the body 600. The first longitudinal transmission assembly 210 may be connected between the travel drive mechanism 110 and the first longitudinal running wheel set 310. Thus, the travel driving mechanism 110 can drive the longitudinal traveling wheels of the first longitudinal traveling wheel set 310 to roll along the longitudinal direction Y-Y through the first longitudinal transmission assembly 210. The second longitudinal transmission assembly 220 may be connected between the travel drive 110 and the second longitudinal running wheel set 320. Thus, the travel driving mechanism 110 can drive the longitudinal traveling wheels of the second longitudinal traveling wheel set 320 to roll along the longitudinal direction Y-Y through the second longitudinal transmission assembly 220.

Illustratively, the first longitudinal running wheel set 310 may be connected with one end of the driving shaft 250 through the first longitudinal transmission assembly 210. In this way, the driving shaft 250 can drive the longitudinal traveling wheels of the first longitudinal traveling wheel set 310 to roll along the longitudinal direction Y-Y through the first longitudinal transmission assembly 210. The second longitudinal running wheel set 320 may be connected to the other end of the driving shaft 250 through the second longitudinal transmission assembly 220. In this way, the driving axle 250 can drive the longitudinal traveling wheels of the second longitudinal traveling wheel set 320 to roll along the longitudinal direction Y-Y through the second longitudinal transmission assembly 220. The travel driving mechanism 110 and the elevation driving mechanism 120 may be spaced apart along the extending direction of the driving shaft 250.

Specifically, as shown in fig. 7-10, each of the first longitudinal drive assembly 210 and the second longitudinal drive assembly 220 may be a flexible drive assembly. The flexible transmission can drive the longitudinal walking wheels to roll through the flexible transmission ring. Flexible drives include, but are not limited to, belt drives, chain drives, or other flexible drives. The first and second longitudinal drive assemblies 210 and 220, respectively, may be one or a combination of belt drive assemblies, chain drive assemblies, or other flexible drive assemblies.

Illustratively, the flexible drive ring may comprise a belt, for example, taking the first longitudinal drive assembly 210 as a belt drive assembly. In this way, the traveling driving mechanism 110 can drive the longitudinal traveling wheels of the first longitudinal traveling wheel set 310 to roll along the longitudinal direction Y-Y through the belt. Illustratively, the flexible drive ring may comprise a chain, for example, with the first longitudinal drive assembly 210 being a chain drive assembly. In this way, the travel driving mechanism 110 can drive the longitudinal travel wheels of the first longitudinal travel wheel set 310 to roll along the longitudinal direction Y-Y through the chains.

The inventor finds that the flexible transmission component has good elasticity compared with other transmission structures, so that the effect of buffering and absorbing vibration can be realized. Moreover, the flexible transmission assembly also has the advantages of stable transmission, low noise, simple structure and the like. Therefore, the traveling driving mechanism 110 is connected to the first longitudinal traveling wheel set 310 and the second longitudinal traveling wheel set 320 through the first longitudinal flexible transmission assembly 210 and the second longitudinal flexible transmission assembly 220, respectively, so that the traveling device operates more stably and has lower noise. Moreover, because the number of the longitudinal traveling wheels in the first longitudinal traveling wheel group 310 and the second longitudinal traveling wheel group 320 is large, if a hard transmission connection assembly of the gear set needs to be provided with more gears, especially in long-distance transmission, while the first longitudinal transmission assembly 210 and the second longitudinal transmission assembly 220 of the present application adopt flexible transmission assemblies, which is very beneficial to realizing transmission connection between the large number of longitudinal traveling wheels. Therefore, the walking device of the application has the advantages of more compact structure and smaller size. Thus, the size of the carrying device can be reduced, and the carrying device can move in a narrower space, so that the carrying device is better in applicability. The carrying system adopting the carrying equipment can also improve the space utilization rate, thereby reducing the cost.

Illustratively, the flexible drive assembly may include a first stage assembly 280 and a second stage assembly 290. The first longitudinal road wheel set 310 may include a ground engaging wheel 350 and a ground engaging wheel 360 spaced apart along the longitudinal direction Y-Y. The second longitudinal road wheel set 320 may also include a ground engaging wheel 350 and a ground engaging wheel 360 spaced apart along the longitudinal direction Y-Y. The travel drive mechanism 110 may be coupled to the ground engaging wheels 350 via the first stage assembly 280. The ground engaging wheels 350 may be connected to the ground engaging wheels 360 through a second stage assembly 290.

When the distance between the longitudinal travelling wheels is too long, the length of the flexible transmission ring is too long. This results in a large bounce and unstable operation of the flexible drive ring during rotation. Moreover, the flexible transmission ring is not easy to arrange, and the difficulty of design and production is high. Simultaneously, in order to prevent that flexible driving ring from droing easily after long-term the use, flexible driving ring need set up more bigger take-up pulleys. And the flexible drive ring may be divided into a plurality of flexible drive rings by staging the flexible drive assemblies into a first stage assembly 280 and a second stage assembly 290. In this way, the length of each flexible drive ring can be relatively shortened. Therefore, each flexible transmission ring has small bounce when rotating and runs stably. Moreover, each flexible transmission ring is easy to arrange, and the design and production difficulty is low. Simultaneously, every flexible drive ring uses still to be difficult for droing after long-term the use, and every flexible drive ring need not to set up too much take-up pulley. More space may be created within first stage assembly 280 and second stage assembly 290 due to the reduction of the tensioner. This space can be exploited, for example, for routing cables, as will be described in more detail below. Therefore, the walking device has a compact structure and a small size.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and that many variations and modifications can be made according to the teachings of the present invention, for example, the flexible transmission assembly may further include a third stage assembly, a fourth stage assembly, and the like. Such variations and modifications are intended to fall within the scope of the present invention as claimed.

Illustratively, the first stage assembly 280 may be located between the second stage assembly 290 and the ground engaging wheels 350 and 360 along the lateral direction X-X. In other words, the ground engaging wheels 350 and ground engaging wheels 360 may be located on one side of the first stage assembly 280 and the second stage assembly 290 may be located on the other side of the first stage assembly 280 in the lateral direction X-X. So set up, second level subassembly 290 and driving and driven wheels 350 and 360 can protect first level subassembly 280, prevent that first level subassembly 280 from being destroyed by external force. Thus, even if the second stage assembly 290 is damaged by external force, the travel drive mechanism 110 can still drive the active travel wheels 350 to roll through the first stage assembly 280, thereby maintaining normal movement.

Illustratively, the ground engaging wheels 350 may include a first ground engaging wheel 351 and a second ground engaging wheel 352. The driven road wheels 360 may include a third road wheel 361 and a fourth road wheel 362. The first and second road wheels 351 and 352 may be located between the third and fourth road wheels 361 and 362 in the longitudinal direction Y-Y. In other words, the third and fourth traveling wheels 361 and 362 may be located at the outer side and the first and second traveling wheels 351 and 352 may be located at the inner side in the longitudinal direction Y-Y. The third travel wheel 361 may be connected to the first travel wheel 351 by a second stage assembly 290. The fourth road wheel 362 may be connected to the second road wheel 352 by another second stage assembly 290. The two second stage components 290 may be the same or different. So configured, the length of each flexible drive ring can be further shortened.

Illustratively, the distance of the third road wheel 361 to the first road wheel 351 is smaller than the distance of the third road wheel 361 to the second road wheel 352 in the longitudinal direction Y-Y. The distance from the fourth row of road wheels 362 to the second road wheel 352 is less than the distance from the fourth row of road wheels 362 to the first road wheel 351. In other words, the third traveling wheel 361, the first traveling wheel 351, the second traveling wheel 352, and the fourth traveling wheel 362 may be arranged in order along the longitudinal direction Y-Y. So configured, the second stage assembly 290 can be connected between adjacent road wheels, thereby shortening the length of the flexible drive loop of the second stage assembly 290. And, the structure of flexible transmission subassembly is more succinct, the overall arrangement of being convenient for. And, by proper arrangement, the two second stage assemblies 290 can adopt the same structure, thereby reducing the variety of components and facilitating the design and production.

Illustratively, the first stage assembly 280 may include a drive wheel 281, a tension wheel 282, and a flexible drive ring 283. The driving wheel 281 may be provided on the driving shaft 250 to coaxially rotate with the driving shaft 250. The flexible driving ring 283 may be sleeved on the shaft of the driving road wheel 350 (i.e., the first road wheel 351 and the second road wheel 352). The driving pulley 281 and the tension pulley 282 may be in contact with the flexible driving ring 283 on both the inner and outer sides of the flexible driving ring 283. It will be appreciated that when the flexible drive assembly is a belt drive assembly, the drive wheel 281 and tension wheel 282 may be pulleys. When the flexible drive assembly is a chain drive assembly, the drive wheel 281 and the tension wheel 282 may be sprockets. The walking drive mechanism 110 can be connected to the driving wheel 281 through the walking transmission mechanism 200 to drive the driving wheel 281 to rotate. The driving wheel 281 can drive the flexible driving ring 283 to rotate, so as to drive the active road wheel 350 to roll along the longitudinal direction Y-Y.

Illustratively, the second stage assembly 290 may include a flexible drive ring 291. The flexible drive ring 291 may be journaled on respective axles of a ground engaging wheel 350 and a ground engaging wheel 360. The driving road wheel 350 rotates along with the flexible driving ring 283, so as to drive the flexible driving ring 291 to rotate, and further drive the driven road wheel 360 to rotate.

The flexible driving ring 283 may be loosened due to abrasion or the like after long-term use, and thus may have poor driving (for example, tooth jumping) or come off. The tension wheel 282 may be used to tension the flexible drive ring 283 to inhibit loosening of the flexible drive ring 283. In addition, the tension wheel 282 can increase the wrap angle between the flexible driving ring 283 and the driving wheel 281, thereby improving the driving torque and reducing the abrasion. Therefore, the first stage assembly 280 has a simple structure and good transmission performance.

Illustratively, the drive wheel 281 may be located outside of the flexible drive ring 283. Tensioning wheel 282 may include a first tensioning wheel 284 and a second tensioning wheel 285. A first tensioning wheel 284 may be located between the first travel wheel 351 and the drive wheel 281. The center of the first tension wheel 284 may be located outside a first line between the center of the first traveling wheel 351 and the center of the driving wheel 281. Here, "outside of the first wire" is with respect to the flexible actuating ring 283, which refers to the side of the first wire facing out of the flexible actuating ring 283. That is, the center of the first tensioning wheel 284 is disposed away from the center of the flexible driving ring 283 with respect to the first connection line. A second tensioning wheel 285 may be located between second road wheel 352 and drive wheel 281. The center of the second tensioning wheel 285 may be located outside of a second line between the center of the second road wheel 352 and the center of the driving wheel 281. Here, "outside of the second connecting line" is also referred to relative to the flexible driving ring 283, which refers to a side of the second connecting line facing outside of the flexible driving ring 283. That is, the center of the second tensioning wheel 285 is located away from the center of the flexible drive ring 283 relative to the second line. So configured, the first tensioning wheel 284 and the second tensioning wheel 285 can further increase the wrap angle of the flexible driving ring 283 and the driving wheel 281, thereby improving the driving torque and reducing the wear.

Illustratively, the walking device may further comprise a longitudinal side panel (e.g. the first longitudinal side panel 621 or the second longitudinal side panel 622, as shown in fig. 5) extending in the longitudinal direction Y-Y. The longitudinal side plates may be provided with a plurality of mounting portions. The tension pulley 282 is selectively mounted to one or more of the plurality of mounting portions to vary the position of the tension pulley 282. Illustratively, the mounting portion may include a long hole 624 provided on the side plate. The tension pulley 282 can move within the elongated hole 624 to change position. With this arrangement, the position of the tension wheel 282 can be adjusted according to the specific structure and wear of the flexible driving ring 283, so that the flexible driving ring 283 can maintain a desired tension.

Illustratively, the longitudinal running wheel group 300 may be disposed outside the longitudinal side plates. The longitudinal transmission assembly may be disposed inboard of the longitudinal side plates. The outer side of the longitudinal side plate refers to the side of the longitudinal side plate facing the outside of the running gear. Exemplarily, as shown in fig. 5, the outer side of the first longitudinal side panel 621 refers to a side of the first longitudinal side panel 621 facing upward and rightward, and the outer side of the second longitudinal side panel 622 refers to a side of the second longitudinal side panel 622 facing downward and leftward.

The axis of the longitudinal road wheels of the first longitudinal road wheel group 310 may pass through the first longitudinal side plate 621 to extend to the inside of the first longitudinal side plate 621. The longitudinal road wheels of the first longitudinal road wheel set 310 are rollable with respect to the first longitudinal side plate 621. The axle of the longitudinal road wheel of the second longitudinal road wheel group 320 may pass through the second longitudinal side plate 622 to extend to the inside of the second longitudinal side plate 622. The longitudinal road wheels of the second longitudinal road wheel set 320 are rollable with respect to the second longitudinal side plate 622. The first longitudinal transmission assembly 210 may be connected to the axle of the longitudinal road wheels of the first longitudinal running wheel set 310, thereby driving the longitudinal road wheels of the first longitudinal running wheel set 310 to roll. The first longitudinal transmission assembly 210 may be connected to the axle of the longitudinal road wheels of the second longitudinal road wheel set 320, thereby driving the longitudinal road wheels of the second longitudinal road wheel set 320 to roll.

The outer side of the longitudinal side plates may also be provided with electrical elements. The electrical components include, but are not limited to, lateral obstacle sensors 912, antennas 991, and the like. Threading holes 623 may be provided in the longitudinal side plates. The cables of the electric components may pass through the threading holes 623 to extend to the inner sides of the longitudinal side plates. The cable for the electrical component includes, but is not limited to, a power cable or a signal cable, etc. So set up, the arrangement of the cable of being convenient for to optimize running gear's inner space.

Illustratively, threading aperture 623 may be located on the inside of flexible drive ring 283. The number and size of the tension pulleys 282 can also be reduced moderately due to the reduced length of the flexible drive ring 283. In this way, more space is created inside the flexible drive ring 283. The cables may be routed within the space. Therefore, the walking device has a compact structure and a small size.

Illustratively, the travel drive mechanism 200 may further include a first transverse drive assembly 230 and a second transverse drive assembly 240. The first traverse driving assembly 230 and the second traverse driving assembly 240 may be disposed at a circumferential side of the body 600.

The first longitudinal transmission assembly 210 and the second longitudinal transmission assembly 220 may be disposed at opposite sides of the main body 600. The first and second traverse drive assemblies 230 and 240 may also be disposed on opposite sides. For example, the first longitudinal driving assembly 210 and the first lateral driving assembly 230 may be disposed at an upper side of the main body 600 in fig. 1. The second longitudinal driving assembly 220 and the second lateral driving assembly 240 may be disposed at a lower side of the body 600 in fig. 1.

The lateral running wheel group 400 may include a first lateral running wheel group 410 and a second lateral running wheel group 420. The first transverse transmission assembly 230 may be connected between the travel drive mechanism 110 and the first transverse running wheel set 410. In this way, the travel driving mechanism 110 can drive the transverse traveling wheels of the first transverse traveling wheel set 410 to roll along the transverse direction X-X through the first transverse transmission assembly 230. A second transverse transmission assembly 240 may be connected between the drive shaft 250 and the second transverse running wheel set 420. In this way, the travel driving mechanism 110 can drive the transverse traveling wheels of the second transverse traveling wheel set 420 to roll along the transverse direction X-X through the second transverse transmission assembly 240.

Specifically, the travel drive mechanism 110 may be coupled to the first cross drive assembly 230 via a first hard drive linkage assembly 710. Also, the travel drive mechanism 110 may be coupled to the second traverse drive assembly 240 via a second hard drive linkage assembly 720.

The gear hard drive comprises a mode of carrying out transmission by meshing a plurality of same or different gears. That is, the first and second hard drive linkage assemblies 710 and 720, respectively, may be gear sets. The gears include, but are not limited to, one or more combinations of cylindrical gears, bevel gears, non-circular gears, racks, and worm gears.

The inventor finds that under the condition that two parts needing transmission connection are close to each other, compared with a structure adopting flexible transmission such as belt transmission or chain transmission, the structure adopting hard gear transmission connection has the advantages of compact structure, high transmission precision, reliable work, small vibration, low noise, long service life, high transmission efficiency and the like. Therefore, the walking driving mechanism 110 is connected with the first transverse transmission assembly 230 and the second transverse transmission assembly 240 through the first hard transmission connecting assembly 710 and the second hard transmission connecting assembly 720, respectively, so that the walking device has a compact structure and a small size. Thus, the size of the carrying device can be reduced, and the carrying device can move in a narrower space, so that the carrying device is better in applicability. The carrying system adopting the carrying equipment can also improve the space utilization rate, thereby reducing the cost.

A first hard drive link assembly 710 may be connected between the drive shaft 250 and the first cross drive assembly 230. The running gear may have a first side (i.e. the upper side in fig. 1) and a second side (i.e. the lower side in fig. 1) opposite in the transverse direction X-X. The first transverse running wheel set 410 and the first transverse transmission assembly 230 may be located on a first side of the running gear opposite in the transverse direction X-X. The travel drive mechanism 110 may be located on a second side of the travel assembly opposite the lateral direction X-X. By providing a drive shaft 250, a remote drive can be achieved.

The first transverse running wheel set 410 and the first transverse transmission assembly 230 may extend in the longitudinal direction Y-Y. The first hard drive connection assembly 710 may include a first bevel gear 711 and a second bevel gear 712. The first bevel gear 711 may be provided on the driving shaft 250 to coaxially rotate with the driving shaft 250. The second bevel gear 712 may be connected to the first cross-drive assembly 230. The first bevel gear 711 and the second bevel gear 712 may mesh. Thus, the axis of the first bevel gear 711 and the axis of the second bevel gear 712 may be perpendicular. The travel drive mechanism 110 can drive the drive shaft 250 to rotate, so as to drive the first bevel gear 711 to rotate. The first bevel gear 711 can drive the second bevel gear 712 to rotate, so as to drive the first transverse transmission assembly 230 to rotate, and further drive the transverse road wheels of the first transverse road wheel set 410 to roll along the transverse direction X-X. So configured, the first transverse traveling wheel set 410 and the first transverse transmission assembly 230 are disposed at one side of the conveying apparatus, so that the occupied middle space of the conveying apparatus can be reduced. Since the driving shaft 250 and the first traverse transmission assembly 230 are perpendicular to each other, transmission can be achieved by providing a first bevel gear 711 and a second bevel gear 712.

The first hard drive coupling assembly 710 may also include a first cylindrical gear 713 and a second cylindrical gear 714. The first cylindrical gear 713 may be coaxially coupled to the second cylindrical gear 712. The second bevel gear 712 is rotatable coaxially with the first cylindrical gear 713. The first cylindrical gear 713 and the second cylindrical gear 712 may be respectively located at both sides of the partition 680. The first cylindrical gear 713 and the second cylindrical gear 712 may be rotatably mounted on the partition 680. The first cylindrical gear 713 and the second cylindrical gear 714 may be meshed.

The first transverse drive assembly 230 may include a first transverse drive shaft 231. A second spur gear 714 may be provided on the first transverse drive shaft 231. The first transverse running wheel set 410 may be fixed to the first transverse transmission shaft 231. The first transverse transmission shaft 231 can drive the transverse road wheels of the first transverse road wheel set 410 to roll along the transverse direction X-X. The travel drive mechanism 110 can drive the drive shaft 250 to rotate, so as to drive the first bevel gear 711 to rotate. The first bevel gear 711 may rotate the second bevel gear 712. The second bevel gear 712 may rotate the first cylindrical gear 713. The first cylindrical gear 713 may drive the second cylindrical gear 714 to rotate, so as to drive the first transverse transmission shaft 231 to rotate, thereby driving the transverse road wheels of the first transverse road wheel set 410 to roll along the transverse direction X-X. With such an arrangement, the first hard drive connecting assembly 710 is simple in structure and small in size.

Specifically, both ends of the first transverse transmission shaft 231 may be provided with first swing portions 232, respectively. The first swing portion 232 may be connected to the lateral road wheels of the first lateral road wheel group 410. Illustratively, the first swinging portion 232 includes, but is not limited to, a retractable spline shaft. When the lateral road wheel is separated from the lateral track, the lateral road wheel and the first swing portion 232 swing relative to the first lateral transmission shaft 231 to generate an angular displacement for tilting. And when the longitudinal travelling wheels are separated from the longitudinal tracks, the transverse travelling wheels fall back to the transverse tracks. The first transverse transmission shaft 231 may be connected to the travel drive mechanism 110. When the direction is changed, the transmission shaft does not lift along with the transverse walking wheels and the longitudinal walking wheels in the process of lifting or descending the transverse walking wheels. Since the first transverse transmission shafts 231 at both ends of the first transverse transmission shaft 231 swing and tilt with respect to the first transverse transmission shaft 231 at the time of reversing, a space in a required height direction is small. Therefore, the carrying equipment can be thinner, the passing performance of the carrying equipment in the carrying system can be improved, the reduction of the space between the shelf layers of the carrying system is facilitated, and the space utilization rate of the carrying system is improved.

For example, the axis of the first cylindrical gear 713 and the axis of the second cylindrical gear 714 may be spaced apart in the vertical direction. So disposed, the driving shaft 250 may be spaced apart from the first transverse transmission shaft 231 in the vertical direction, thereby preventing interference from occurring.

Illustratively, the travel drive mechanism 110 may include a first output 111 and a second output 112. The first output 111 may be connected to a drive shaft 250. The first output end 111 can drive the driving shaft 250 to rotate, so as to drive the transverse road wheels in the first transverse road wheel set 410 to roll along the transverse direction X-X, and simultaneously drive the longitudinal road wheels in the first longitudinal road wheel set 310 and the second longitudinal road wheel set 320 to roll along the longitudinal direction Y-Y. The second output 112 may be coupled to the second traverse assembly 240 via a second traverse assembly, such as a second hard drive linkage assembly 720. Thus, only one travel drive mechanism 110 may be provided to drive the transverse road wheels of the transverse road wheel set 400 to roll in the transverse direction X-X.

Illustratively, the second transverse transmission assembly 240 and the second transverse running wheel set 420 may be located on a second side of the running gear in the transverse direction X-X. So configured, the travel drive mechanism 110 is closer to the second transverse transmission assembly 240, thereby facilitating gear transmission.

Illustratively, the second transverse running wheel set 420 and the second transverse transmission assembly 240 may extend in the longitudinal direction Y-Y, respectively. The axis of rotation of the second output 112 may extend in the longitudinal direction Y-Y. Thus, the axes of rotation of the second transverse running wheel set 420, the second transverse transmission assembly 240 and the second output 112 may be parallel to each other. In this way, gear transmission may be facilitated, thereby making the structure of the second hard drive connection assembly 720 more compact.

Illustratively, the second transverse drive assembly 240 may include a second transverse drive shaft 241. The second hard drive link assembly 720 may include a third cylindrical gear 721 and a fourth cylindrical gear 722. A third cylindrical gear 721 may be provided on the second output 112. The second output 112 may rotate the third cylindrical gear 721. A fourth spur gear 722 may be provided on the second transverse transmission shaft 241. The third cylindrical gear 721 may be meshed with the fourth cylindrical gear 722. The second output end 112 of the travel driving mechanism 110 can drive the third cylindrical gear 721 to rotate, so as to drive the fourth cylindrical gear 722 to rotate, thereby driving the second transverse transmission shaft 241 to rotate, and further driving the transverse traveling wheels of the second transverse traveling wheel set 420 to roll along the transverse direction X-X. So configured, the second hard drive connection assembly 720 is compact in structure and small in size.

Specifically, both ends of the second transverse transmission shaft 241 may be provided with second swing parts 242, respectively. The second swing portion 242 may be connected to the lateral road wheels of the second lateral road wheel group 420. The operation principle of the second transverse transmission shaft 241 and the second swinging portion 242 is substantially the same as the operation principle and the technical effect of the first transverse transmission shaft 231 and the first swinging portion 232, and therefore, for brevity, the detailed description is omitted.

Illustratively, the first longitudinal driving assembly 210, the second longitudinal driving assembly 220, the first lateral driving assembly 230, and the second lateral driving assembly 240 may be disposed on a circumferential side of the main body 600. Thus, the occupation of the middle space of the main body 600 can be reduced, so that a more regular space can be formed in the middle. The large-sized components such as the travel drive mechanism 110, the elevation drive mechanism 120, the power supply unit 810, and the electric unit 820 can be disposed in the space, and the layout can be simplified. In addition, the above components can be arranged more compactly, which facilitates the miniaturization of the conveying apparatus.

Illustratively, the first longitudinal transmission assembly 210 and the second longitudinal transmission assembly 220 may be located on both sides of the handling apparatus. Therefore, the first longitudinal transmission assembly 210 is closer to the first longitudinal traveling wheel set 310, and the second longitudinal transmission assembly 220 is closer to the second longitudinal traveling wheel set 320, so that the connection is facilitated, the space occupied by the connection is reduced, and the structure of the carrying device is more compact.

Illustratively, the body 600 may also include a first longitudinal partition 631 and a second longitudinal partition 632. The first longitudinal partition 631 may be disposed inside the first longitudinal side panel 621. The first longitudinal partition 631 may be disposed spaced apart from the first longitudinal side panel 621 to form an elongated first longitudinal cavity 641. The first longitudinal transmission assembly 210 may be located within the first longitudinal cavity 641. A second longitudinal partition 632 may be disposed inboard of the second longitudinal side panel 622. The second longitudinal partition 632 may be spaced apart from the second longitudinal side panel 622 to form an elongated second longitudinal cavity 642. The second longitudinal drive assembly 220 may be located within the second longitudinal cavity 642. By such an arrangement, the substances such as the lubricating oil in the first longitudinal transmission assembly 210 and the second longitudinal transmission assembly 220 can be prevented from flowing out, and the other parts can be prevented from being polluted. In addition, the dust and other impurities can be prevented from entering, and the transmission effect of the first longitudinal transmission assembly 210 and the second longitudinal transmission assembly 220 is reduced.

For example, the travel driving mechanism 110 and the elevation driving mechanism 120 may be disposed between the first longitudinal partition 631 and the second longitudinal partition 632. The travel drive 110 may be adjacent to the second longitudinal partition 632. The lift drive mechanism 120 may be adjacent the first longitudinal partition 631. The adjacency includes abutting or being spaced apart by a predetermined distance. The predetermined distance may be as small as possible. With this arrangement, a large space can be formed between the travel drive mechanism 110 and the lift drive mechanism 120, and it is convenient to install components such as the power module 810, thereby improving the space utilization in the conveying apparatus.

For example, the elevation driving mechanism 500 may include a first elevation driving mechanism 510 and a second elevation driving mechanism 520. The first elevation drive mechanism 510 and the second elevation drive mechanism 520 may be located at a first side (i.e., a left side in fig. 1) and a second side (i.e., a right side in fig. 1) of the conveyance apparatus in the longitudinal direction Y-Y, respectively. The first elevation drive mechanism 510 may be connected between the lateral road wheels on the first side of the transfer apparatus in the longitudinal direction Y-Y in the lateral road wheel set 400 and the elevation drive mechanism 120. The elevation driving mechanism 120 may drive the lateral travel wheels of the first side of the transfer apparatus in the longitudinal direction Y-Y to be elevated by the first elevation driving mechanism 510. The second elevation drive mechanism 520 may be connected between the lateral road wheels on the second side of the transfer apparatus in the longitudinal direction Y-Y in the lateral road wheel set 400 and the elevation drive mechanism 120. The elevation driving mechanism 120 may drive the lateral traveling wheels of the second side of the transfer apparatus in the longitudinal direction Y-Y to ascend and descend through the second elevation transmission mechanism 520. Thus, the occupation of the middle space of the main body 600 can be reduced, so that a more regular space can be formed in the middle. The large-sized components such as the travel driving mechanism 110 and the elevation driving mechanism 120 are more convenient to arrange, so that the layout difficulty can be simplified. In addition, the related components can be arranged more compactly, and the carrying equipment can be miniaturized conveniently. And, first lift drive mechanism 510 and second lift drive mechanism 520 can be connected with the horizontal walking wheel nearby respectively to can be convenient for connect, reduce because of connecting the space that occupies, make the structure of haulage equipment comparatively compact.

Illustratively, the body 600 may further include a first transverse partition 661 and a second transverse partition 662. The first lateral partition 661 may be disposed inside the first lateral side plate 651. The first lateral partition 661 may be disposed spaced apart from the first lateral side plate 651 to form a first laterally long lateral cavity 671. The first elevation drive mechanism 510 and the lateral road wheels of the lateral road wheel set 400 on the first side of the transfer apparatus in the longitudinal direction Y-Y may both be located within the first lateral cavity 671. A second transverse partition 662 may be disposed inboard of the second transverse side plate 652. A second transverse partition 662 may be disposed in spaced relation to the second transverse side plate 652 to form a second transversely elongated transverse cavity 672. The second elevation drive 520 and the lateral road wheels of the lateral road wheel set 400 on the second side of the transfer apparatus in the longitudinal direction Y-Y are both located in a second lateral cavity 672. With this arrangement, it is possible to prevent substances such as lubricating oil in the first lifting transmission mechanism 510 and the second lifting transmission mechanism 520 from flowing out and causing contamination of other components. In addition, the first lifting transmission mechanism 510 and the second lifting transmission mechanism 520 can be prevented from lowering the lifting effect due to the entering of dust and other impurities. Meanwhile, the transverse traveling wheels in the transverse traveling wheel group 400 can be protected from being damaged by external force.

For example, the first traverse driving assembly 230, the first traverse traveling wheel group 410 and the first longitudinal driving assembly 210 may be located at one side of the handling apparatus. Illustratively, the first transverse transmission assembly 230, the first transverse traveling wheel set 410 and the first longitudinal transmission assembly 210 may be all located in the first longitudinal cavity 641. The second transverse driving assembly 240, the second transverse traveling wheel set 420 and the second longitudinal driving assembly 220 may be located at the other side of the carrying apparatus. Illustratively, the second transverse transmission assembly 240, the second transverse traveling wheel set 420, and the second longitudinal transmission assembly 220 may all be located within the second longitudinal cavity 642. In this way, the first transverse transmission assembly 230 and the second transverse transmission assembly 240 are closer to the first transverse traveling wheel set 410 and the second transverse traveling wheel set 420, respectively, so that the connection can be facilitated, the space occupied by the connection can be reduced, and the structure of the carrying device is compact. Moreover, the first longitudinal transmission assembly 210 and the first transverse transmission assembly 230 are closer to each other, and the second longitudinal transmission assembly 220 and the second transverse transmission assembly 240 are closer to each other, so that centralized protection and maintenance can be facilitated.

For example, the number of lateral road wheels in the lateral road wheel set 400 may be less than the number of longitudinal road wheels in the longitudinal road wheel set 300. In this way, the structure of the transverse transmission assembly (e.g., the first transverse transmission assembly 230 and the second transverse transmission assembly 240) for connecting the transverse traveling wheel set 400 may be relatively compact. The elevation driving mechanism 120 may be connected to the transverse traveling wheel assembly 400 through an elevation driving mechanism 500, so that the transverse traveling wheel assembly 400 may be driven to be elevated. With this arrangement, the load of the lift drive mechanism 120 can be reduced, and the conveyance apparatus can be made more energy-saving.
