Description

Technical Field

[0001] The utility model relates to the technical field of logistics warehousing systems, in particular to a thin four-way shuttle vehicle. Background Art

[0002] The four-way shuttle is an intelligent shuttle handling equipment that integrates four-way travel, on-site track change, automatic handling, intelligent monitoring and dynamic traffic management. The four-way shuttle can travel along the longitudinal or transverse track on the cross track to reach any designated cargo position in the warehouse. It is not restricted by the site and can adapt to a variety of working environments. The terminal can be freely dispatched to achieve full automatic unattended operation. With the rapid development of the logistics and warehousing industry, the large-scale use of existing three-dimensional warehousing, and the rapid growth of logistics and storage volume, higher requirements have been put forward for the storage capacity of three-dimensional warehousing.

[0003] The power transmission of traditional four-way shuttle vehicles usually adopts chain transmission, and chain transmission often requires a multi-stage transmission structure to realize the travel transmission and reversing transmission of the four-way shuttle vehicle, which not only affects the transmission accuracy and transmission efficiency, but also the multi-stage chain transmission structure will make the body thickness of the four-way shuttle vehicle thicker. It is necessary to leave a large enough height space close to the ground in the stereoscopic warehouse to ensure the normal operation of the four-way shuttle vehicle in the stereoscopic warehouse. This will inevitably cause a reduction in the number of shelf layers in the stereoscopic warehouse, making the storage capacity of the stereoscopic warehouse unable to meet people's expectations.

Unless mentioned otherwise, a term in the singular form may include a plural form and should not be understood as being one in number.

[0030] In addition, the drawings are not drawn to a 1:1 scale, and the relative sizes of the elements in the drawings are drawn only as examples and not necessarily according to the true scale.

[0031] Figure 1 The structure of a thin four-way shuttle in one embodiment of the utility model is shown. For ease of description, the accompanying drawings only show structures related to the utility model embodiment.

[0032] See also Figure 1 The thin four-way shuttle 100 in the preferred embodiment of the utility model includes a vehicle body 110, two transverse walking mechanisms 120, two longitudinal walking mechanisms 130, a walking power assembly (not shown) and two reversing lifting mechanisms 140.

[0033] The vehicle body 110 includes a bottom plate 111, two transverse side plate structures 112, two longitudinal side plate structures 113 and two reversing side plate structures 114. The two transverse side plate structures 112 are spaced apart on the bottom plate 111. The two longitudinal side plate structures 113 are spaced apart on the bottom plate 111, and each longitudinal side plate structure 113 is connected between the two transverse side plate structures 112. The two reversing side plate structures 114 are slidably mounted on the outer sides of the two longitudinal side plate structures 113, respectively.

[0034] Please also read Figure 2 The two transverse walking mechanisms 120 correspond to the two transverse side plate structures 112 one by one. The transverse walking mechanism 120 includes a transverse wheel 122 disposed on the corresponding transverse side plate structure 112 and a belt transmission assembly 121 connected to the transverse wheel 122 in a transmission manner.

[0035] Specifically, the belt drive assembly 121 includes an input pulley 1211, two tension pulleys 1212 arranged at intervals along the travel direction of the transverse wheel 122, a travel pulley 1214 connected to the axle of the transverse wheel 122, and a transmission belt 1214 tensioned on the two tension pulleys 1212. The input pulley 1211 and the travel pulley 1214 are arranged at intervals between the two tension pulleys 1212. An idler pulley 1215 is arranged between the travel pulley 1214 and the input pulley 1211. The transmission belt 1214 is respectively sleeved on the input pulley 1211 and the travel pulley 1214, and is wound around each idler pulley 1215 from the outside. In this way, it can be ensured that all transmission components in the belt drive assembly are in the same plane (i.e., the plane parallel to the traveling direction of the transverse wheel), and the power transmission from the traveling power assembly to the transverse wheel 122 can be realized with the simplest and most reliable structure. The setting of the idler wheel 1215 and the tensioning pulley 1212 can ensure that the belt drive assembly 121 has higher transmission accuracy and transmission reliability.

[0036] Of course, in other embodiments, the belt drive assembly 121 may also be other forms of belt drive structures, such as directly tightening the drive belt 1214 on the input pulley 1211 and the travel pulley 1214 , and so on.

[0037] Please also read Figure 3 The two longitudinal running mechanisms 130 correspond to the two reversing side plate structures 114 one by one. The longitudinal running mechanisms 130 include longitudinal driving wheels 131 and longitudinal driven wheels 132 arranged on the corresponding reversing side plate structures 114.

[0038] The travel power assembly is respectively connected to the belt drive assembly 121 and the longitudinal driving wheel 131. The travel power assembly is arranged in the vehicle body 110 and is used to drive the longitudinal driving wheel 131 to rotate and the belt drive assembly 121 to operate, so as to transmit power to the transverse wheel 122 through the belt drive assembly 121, thereby achieving the purpose of driving the vehicle body 110 to travel on the transverse track or the longitudinal track.

[0039] Specifically, when the belt drive assembly 121 includes an input pulley 1211, two tension pulleys 1212, a travel pulley 1214 and a transmission belt 1214, the travel power assembly is connected to the input pulley 1211, that is, the travel power assembly drives the belt drive assembly 121 to operate by transmitting power to the input pulley 1211.

[0040] The two reversing lifting mechanisms 140 correspond to the two reversing side plate structures 114 one by one. The reversing lifting mechanism 140 includes a gear transmission assembly 141, a reversing lifting assembly (not shown) disposed on the reversing side plate structure 114, and a reversing power assembly (not shown) connected to the gear transmission assembly 141. The reversing lifting assembly is connected to the gear transmission assembly 141. The reversing lifting assembly is a conventional structure in the existing four-way shuttle, and will not be described in detail here.

[0041] Specifically, the gear transmission assembly 141 includes an input gear 1411, a transition gear 1412 and a reversing and lifting gear 1413 which are arranged at intervals and meshed with each other along the traveling direction of the longitudinal driving wheel 131. The input gear 1411 is in driving connection with the output shaft of the reversing power assembly. The reversing and lifting gear 1413 is in driving connection with the reversing and lifting assembly. In this way, it can be ensured that all components in the gear transmission assembly 141 are in the same plane (i.e., a plane parallel to the traveling direction of the longitudinal driving wheel 131), and the power is transmitted from the reversing power assembly to the reversing and lifting assembly with the simplest and most reliable structure. The setting of the transition gear 1412 can ensure that the gear transmission assembly 141 has a high transmission accuracy.

[0042] Of course, in other embodiments, the gear transmission assembly 141 can also be other forms of gear transmission structures, such as the input gear 1411 directly meshing with the reversing jacking gear 1413, or some gears with functions such as changing the transmission direction are arranged in the gear transmission assembly 141, etc., as long as it can be ensured that power can be transmitted from the reversing power assembly to the reversing jacking assembly.

[0043] Among them, the reversing power assembly is arranged in the vehicle body 110, and is used to drive the reversing lifting assembly to operate through the input gear 1411, the transition gear 1412 and the reversing lifting gear 1413, so as to drive the reversing side plate structure 114 to drive the longitudinal active wheel 131 and the longitudinal driven wheel 132 to rise and fall, so as to ensure that the driving direction of the thin four-way shuttle 100 is switched between the transverse track direction and the longitudinal track direction, so as to achieve the purpose of free reversing.

[0044] Specifically, the reversing side plate structure 114 can slide relative to the longitudinal side plate structure 113 in a direction perpendicular to the bottom plate 111. Of course, in other embodiments, the sliding direction of the reversing side plate structure 114 can also slightly deviate from the direction perpendicular to the bottom plate 111, as long as the height of the longitudinal active running wheel and the longitudinal driven running wheel can be driven to change.

[0045] Compared with the multi-stage chain drive in the conventional four-way shuttle, the above-mentioned thin four-way shuttle 100 has a single-stage belt drive with the belt drive assembly 121, which not only improves the transmission efficiency and transmission accuracy between the travel power assembly and the transverse wheels 122 and the longitudinal driving wheels 131, but also helps to reduce the thickness of the vehicle body at the transverse side plate structure 112 along the height direction. At the same time, the setting of the gear transmission assembly 141 helps to reduce the thickness of the vehicle body 110 at the longitudinal side plate structure along the height direction, thereby making the overall thickness of the vehicle body thinner.

[0046] In a high-rise warehouse, mutually intersecting transverse and longitudinal tracks are laid between the shelves, and the thin four-way shuttle 100 automatically stores and retrieves goods by moving on these transverse and longitudinal tracks. Therefore, the height of the layer of the shelf closest to the ground is higher than the top surface height of the thin four-way shuttle 100 when it is on the transverse track or the longitudinal track.

[0047] Therefore, by using the above-mentioned thinner vehicle body 110, the top surface position height of the thin four-way shuttle 100 on the transverse track or the longitudinal track can be reduced. In a three-dimensional warehouse of the same height, the space height above the thin four-way shuttle 100 is larger, so that more layers of shelves can be arranged under the same floor height to improve the storage capacity of the three-dimensional warehouse.

[0048] It should be noted that, in the above-mentioned transverse side panel structure 112, longitudinal side panel structure, transverse running mechanism, longitudinal running mechanism 130, transverse guide rail and longitudinal guide rail, the transverse and longitudinal directions are only for distinguishing the side walls in different directions on the vehicle body 110, distinguishing the running mechanisms in two directions, and distinguishing the guide rails that are staggered and in different directions, so as to facilitate the correspondence of the side panel structure, running mechanism and guide rail in the same direction, and it is not a limitation of the transverse and longitudinal directions in the conventional sense.

[0049] In some embodiments, the belt drive assembly 121 includes two groups of travel pulleys 1214. The two groups of travel pulleys 1214 are arranged at intervals along the travel direction of the transverse travel wheel and are located on both sides of the input pulley 1211. Each group of travel pulleys 1214 includes at least one travel pulley 1214. Each travel pulley 1214 is connected to a transverse wheel 122 in a transmission manner. In this way, each group of travel pulleys 1214 may include only one travel pulley 1214 or may include multiple travel pulleys 1214. When each group of travel pulleys 1214 includes two or more travel pulleys 1214, an idler wheel 1215 is provided between each two adjacent travel pulleys 1214.

[0050] Since each traveling pulley 1214 is in transmission connection with a transverse wheel 122 , two sets of transverse wheels 122 are correspondingly provided on each transverse side plate structure 112 to ensure that the thin four-way shuttle 100 has higher stability and better stability when traveling on the transverse track.

[0051] In some embodiments, there are multiple input pulleys 1211. Multiple input pulleys 1211 are arranged at intervals along the travel direction of the transverse wheel 122. An idler pulley 1215 is arranged between two adjacent input pulleys 1211. The travel power assembly can be selectively connected to one of the input pulleys 1211 in each group of belt transmission components 121. Specifically, when the belt transmission component 121 includes two groups of travel pulleys 1214, the multiple input pulleys 1211 are located between the two groups of travel pulleys 1214.

[0052] In this way, during the manufacturing process of the thin four-way shuttle 100, the travel power assembly can be connected to one of the input pulleys 1211 in each belt drive assembly 121 according to different design requirements, so as to improve the installation freedom of the travel power assembly in the thin four-way shuttle 100, and be suitable for the assembly of different thin four-way shuttles 100 to facilitate the installation of the travel power assembly.

[0053] In some embodiments, the tension pulley 1212, the travel pulley 1214 and the idler wheel 1215 can be rotatably mounted on the corresponding transverse side plate structure 112. In this way, the belt drive assembly 121 and the transverse wheel 122 are all mounted on the transverse side plate structure 112, making the structure of the thin four-way shuttle 100 more compact, and making the installation space in the vehicle body 110 larger, which is convenient for the installation of various components in the vehicle body 110.

[0054] Of course, in other embodiments, the tension pulley 1212 , the travel pulley 1214 and the idler pulley 1215 may also be installed on other supporting structures independent of the transverse side plate structure 112 .

[0055] Further, in some embodiments, the belt drive assembly 121 further includes a belt tensioning structure 1216. The belt tensioning structure 1216 is mounted on the lateral side plate structure 112 and is configured to drive one tensioning pulley 1212 to move in a direction away from the other tensioning pulley 1212. There may be one or two belt tensioning structures 1216. When there are two belt tensioning structures 1216, the two belt tensioning structures 1216 correspond to the two tensioning pulleys 1212 one by one, and are used to drive the corresponding tensioning pulleys 1212 to move in a direction away from the other tensioning pulley 1212.

[0056] In actual use, if the transmission belt 1214 becomes loose, the staff only needs to use the belt tensioning structure 1216 to increase the distance between the two tensioning pulleys 1212 to adjust the tension of the transmission belt 1214 to ensure effective and reliable transmission of the belt drive assembly 121.

[0057] Specifically, a threaded adjustment hole (not shown) is provided on the axle of the tension pulley 1212. The belt tensioning structure 1216 includes a tensioning adjustment seat 12161 and an adjustment screw 12162. The tensioning adjustment seat 12161 has a second threaded connection hole and is mounted on the lateral side plate structure 112. One end of the adjustment screw 12162 is threadedly connected to the threaded connection hole, and the other end is threadedly connected to the threaded adjustment hole.

[0058] When the transmission belt is loose and needs to be adjusted, the staff turns the adjusting screw 12162 to drive the tensioning pulley 1212 to move away from the other tensioning pulley 1212, thereby adjusting the distance between the two tensioning pulleys 1212 and adjusting the tension of the transmission belt 1214. The operation is convenient and quick.

[0059] Of course, in other embodiments, the belt tensioning structure 1216 may also be other tensioning structures, such as a tensioning wheel that tightens the transmission belt 1214 by moving the installation position, etc.

[0060] In some embodiments, there are two input gears 1411. The two input gears 1411 are arranged at intervals along the travel direction of the longitudinal driving wheel 131 and are respectively located on both sides of the reversing and lifting gear 1413. A transition gear 1412 is arranged between each input gear 1411 and the adjacent reversing and lifting gear 1413. The reversing power assembly can be selectively connected to one of its input gears 1411. The arrangement of the two input gears 1411 enables the thin four-way shuttle 100 to realize selectable bidirectional drive when the travel direction is switched, so as to ensure that the travel direction switching work is reliable and convenient.

[0061] In some embodiments, there are multiple reversing and lifting gears 1413. The multiple reversing and lifting gears 1413 are arranged at intervals along the traveling direction of the longitudinal driving wheel 131. An intermediate gear 1414 meshing with the adjacent two reversing and lifting gears 1413 is also arranged between them.

[0062] The multiple reversing lifting gears 1413 can perform multi-point driving on the reversing side plate structure 114 to ensure that the reversing side plate structure 114 can stably and reliably drive the longitudinal driving wheel 131 and the longitudinal driven wheel 132 to rise and fall, thereby improving the stability and reliability of the switching of the walking direction of the thin four-way shuttle 100.

[0063] Furthermore, in some embodiments, the reversing lifting gear 1413 and the intermediate gear 1414 have the same size and structure, and the central axes of the multiple reversing lifting gears 1413 and the intermediate gear 1414 pass through the same straight line. In this way, the rotation speed and rotation direction of the multiple reversing lifting gears 1413 can be ensured to be the same, so that the multiple reversing lifting gears 1413 can synchronously drive the reversing side plate structure 114, making the lifting process of the reversing side plate structure 114 more stable, further ensuring the smooth and reliable switching of the walking direction of the thin four-way shuttle 100.

[0064] In some embodiments, the input gear 1411, the transition gear 1412, and the reversing and lifting gear 1413 can be rotatably mounted on the corresponding longitudinal side plate structure 113. In this way, the input gear 1411, the transition gear 1412, and the reversing and lifting gear 1413 are all mounted on the longitudinal side plate structure 113, making the structure of the thin four-way shuttle 100 more compact, and making the space inside the vehicle body 110 larger, which is convenient for the installation of various components inside the vehicle body 110.

[0065] Of course, in other embodiments, the input gear 1411 , the transition gear 1412 and the reversing and lifting gear 1413 may also be installed on a supporting structure independent of the longitudinal side plate structure 113 .

[0066] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
