Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shuttle vehicle devices, in particular to a traction-type shuttle vehicle. Background Art
[0002] With the development of science and technology, more and more storage logistics have been widely used, and intelligent vertical warehouse storage and handling equipment has been studied intensively. As an important handling tool for vertical warehouse storage logistics, shuttle cars currently mainly use a lifting mechanism to lift the goods and walk along the track inside the shelf to achieve the function of transferring goods inside the shelf. Currently, shuttle cars are divided into three types according to the lifting mechanism: hydraulic lifting, cam lifting, and screw lifting.
[0003] Traditional shuttle vehicles use the method of completely lifting the goods before transporting them. The weight of the goods and the weight of the vehicle body are borne by the running tracks. On the one hand, the running tracks and load-bearing shelves require very high rigidity and are relatively expensive. On the other hand, due to the limited carrying capacity of the running tracks and shelves, the weight of the goods that the shuttle vehicle can transport is limited under this method. Currently, the carrying capacity of conventional shuttle vehicles does not exceed 1.5 tons, which limits its application in heavy-load three-dimensional storage systems.
[0004] In addition, from the perspective of the jacking mechanism, when handling heavy goods, a larger jacking force should be provided. Shuttle vehicles mostly use hydraulic jacking mechanisms, which have complex structures and high production, maintenance and servicing costs. In addition, whether a series or parallel system is used, there is an output imbalance and the risk of cargo tilting; especially if the device leaks, it is easy to cause pollution.
[0005] In view of this, in order to solve the dilemma of traditional shuttle vehicles when handling heavy goods, we propose a towing shuttle vehicle. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0027] See also Figures 1 to 4 , the utility model provides a technical solution:
[0028] A traction shuttle vehicle comprises a traction shuttle vehicle body 1, a positioning pin lifting assembly 2 is installed inside the traction shuttle vehicle body 1, a walking assembly 3 is installed inside the traction shuttle vehicle body 1, and a lifting mechanism assembly 4 is installed inside the traction shuttle vehicle body 1. The positioning pin lifting assembly 2 comprises: a transmission motor 21, a transmission gear 22, a transmission gear 23, a connecting shaft 24, a spiral elevator 25, a positioning pin lifting block 26, a spiral elevator 27, a positioning pin lifting block 28, etc. A transmission motor 21 is installed at the front end of the positioning pin lifting assembly 2, and a transmission gear 22 is installed at the output end of the transmission motor 21.

A screw elevator 27 is installed at the other end of the connecting shaft 24. A positioning pin lifting block 28 is installed at the output end of the screw elevator 27.
[0029] It should be added that, by locating the lifting mechanism assembly 4 in the middle of the shuttle, the cargo is slightly lifted by the lifting mechanism assembly 4, the friction between the shuttle and the track is increased, and the shuttle can provide sufficient traction when transporting cargo. The positioning pin lifting assembly 2 is located on both sides of the shuttle, and the cargo is pulled by lifting the positioning pin lifting block 26. The walking assembly 3 is located between the lifting mechanism assembly 4 and the positioning pin lifting assembly 2, and is used for the normal travel of the shuttle. When the shuttle locates the cargo and reaches the predetermined position, the positioning pin lifting assembly 2 starts to start first, and the transmission motor 21 provides power, which is transmitted through the transmission gear 22 and the transmission gear 23 to drive the connecting shaft 24 to rotate. The two ends of the connecting shaft 24 are connected with the spiral elevator 25 and the spiral elevator 27. The rotation of the connecting shaft 24 can drive the screw rods in the spiral elevator 25 and the spiral elevator 27 to rotate, so that the corresponding positioning pin lifting block 26 and the positioning pin lifting block 28 start to rise synchronously, and the two positioning pins on the other side of the shuttle rise in the same way.
[0030] As a preferred embodiment of the present invention, the walking assembly 3 includes: a servo motor 31, a transmission gear three 32, a transmission gear four 33, a connecting shaft two 34, a walking wheel 35, etc. The servo motor 31 is installed on the inner side of the walking assembly 3, and the transmission gear three 32 is installed on the output end of the servo motor 31. The transmission gear three 32 is meshed with the transmission gear four 33. The connecting shaft two 34 is fitted on the axial hole of the transmission gear four 33. Walking wheels 35 are installed at both ends of the connecting shaft two 34. A battery 36 is installed on the side of the servo motor 31, and a lifting mechanism assembly 4 is installed at the front end of the battery 36.
[0031] As a preferred embodiment of the present invention, the lifting mechanism assembly 4 includes: a lifting motor 41, a transmission gear five 42, a transmission gear six 43, a connecting shaft three 44, a cam 45, a lower lifting plate 46, a guide shaft 47, a spring 48, an upper lifting plate 49, etc. The lifting mechanism assembly 4 is equipped with a lifting motor 41 inside, and the output end of the lifting motor 41 is equipped with a transmission gear five 42, a transmission gear five 42 and a transmission gear six 43, the shaft hole of the transmission gear six 43 is fitted with the connecting shaft three 44, and cams 45 are installed at both ends of the connecting shaft three 44, and a lower lifting plate 46 is attached to the cam 45, and a guide shaft 47 is installed on the lower lifting plate 46, and a spring 48 is sleeved on the guide shaft 47, and an upper lifting plate 49 is connected to the spring 48.
[0032] It is worth noting that after the positioning pin is raised at the specified position, the lifting mechanism assembly 4 starts to start, and the motor 41 drives the connecting shaft 3 44 to rotate through the transmission gear 5 42 and the transmission gear 6 43. Cams 45 are fixed at both ends of the connecting shaft 3 44. The cams 45 and the connecting shaft 3 44 rotate synchronously in the same direction. The lower lifting plate 46 rotates with the cam 45 to realize the lifting function. Several springs 48 are evenly fixed on the lower lifting plate 46. The other side of the spring 48 is connected to the upper lifting plate 49. When the lower lifting plate 46 rises, the upper lifting plate 49 rises accordingly. When the upper lifting plate When 49 contacts the bottom surface of the cargo 6, the lower lifting plate 46 continues to rise. Due to the heavy weight of the cargo 6, the upper lifting plate 49 cannot continue to rise, and the distance between the upper lifting plate 49 and the lower lifting plate 46 is reduced, that is, the spring 48 is compressed, and the lower lifting plate 46 stops after rising to a certain height. At this time, the spring 48 is compressed, and the traction shuttle body 1 is subjected to the downward pressure of the spring 48. The positive pressure between the traction shuttle and the track 7 becomes larger, which increases the static friction between the running wheel 35 and the track 7, ensuring that the shuttle can provide sufficient traction when transporting goods.
[0033] During specific use, after the shuttle car completes the lifting and micro-lifting of the positioning pin, the walking component 3 starts to start, and the servo motor 31 drives the connecting shaft 2 34 to rotate through the transmission gear 3 32 and the transmission gear 4 33. The connecting shaft 2 34 is fixed with walking wheels 35 at both ends. The walking wheels 35 rotate synchronously with the connecting shaft 2 34 in the same direction, thereby realizing the travel of the trolley.
[0034] As a preferred embodiment of the present invention, a cargo detection operation is performed by using a cargo detection sensor 8 installed on the towing shuttle vehicle body 1 to detect whether there is cargo in the target storage location.
[0035] As a preferred embodiment of the present invention, the cargo 6 is positioned by a positioning sensor 9 installed on the towing shuttle body 1 to ensure that the shuttle can accurately position the cargo 6 .
[0036] When the utility model is in use, firstly, the situation of the target warehouse goods 6 is detected by the cargo detection sensor 8 to ensure that there is cargo in the warehouse, and the cargo 6 is accurately positioned by the positioning sensor 9 to ensure that the relative position relationship between the shuttle and the cargo 6 is accurate, and the cargo 6 is slightly lifted by the lifting mechanism component 4 to increase the friction between the shuttle and the track 7 to ensure that the shuttle can provide sufficient traction when transporting cargo. The positioning pin lifting components 2 are located on both sides of the shuttle, and the cargo is pulled by lifting the positioning pin lifting block 1 26 and the positioning pin lifting block 2 28. The walking component 3 is located between the lifting mechanism component 4 and the positioning pin lifting component 2, and is used for the normal travel of the shuttle. When the cargo 6 is positioned and reaches the predetermined position, the positioning pin lifting assembly 2 starts to start first, and the transmission motor 21 provides power, which is transmitted through the transmission gear 22 and the transmission gear 23 to drive the connecting shaft 24 to rotate. The two ends of the connecting shaft 24 are connected with the spiral elevator 25 and the spiral elevator 27. The rotation of the connecting shaft 24 can drive the screw rods in the spiral elevator 25 and the spiral elevator 27 to rotate, so that the corresponding positioning pin lifting block 1 26 and the positioning pin lifting block 2 28 start to rise synchronously, and the two positioning pins on the other side of the shuttle car rise in the same way. After the positioning pin is raised at the specified position, the lifting mechanism assembly 4 starts to start, and the motor 41 drives the connecting shaft 3 44 to rotate through the transmission gear 5 42 and the transmission gear 6 43. Cams 45 are fixed at both ends of the connecting shaft 3 44. The cams 45 and the connecting shaft 3 44 rotate synchronously in the same direction. The lower lifting plate 46 realizes the lifting function as the cam 45 rotates. Several springs 48 are evenly fixed on the lower lifting plate 46. The other side of the spring 48 is connected to the upper lifting plate 49. When the lower lifting plate 46 rises, the upper lifting plate 49 rises accordingly. When the upper lifting plate 49 contacts the bottom surface of the cargo 6, the lower lifting plate 46 continues to rise. Due to the heavy weight of the cargo 6, the upper lifting plate 49 cannot continue to rise, and the distance between the upper lifting plate 49 and the lower lifting plate 46 is reduced, that is, the spring 48 is The compression, lower lifting plate 46 rises to a certain height and then stops. At this time, the spring 48 is compressed, and the traction shuttle body 1 is subjected to the downward pressure of the spring 48. The positive pressure between the traction shuttle and the track 7 becomes larger, and the static friction between the running wheel 35 and the track 7 is increased to ensure that the shuttle can provide sufficient traction when transporting goods. When the shuttle completes the positioning pin lifting and micro-lifting, the walking component 3 starts to start, and the servo motor 31 drives the connecting shaft 2 34 to rotate through the transmission gear three 32 and the transmission gear four 33. The connecting shaft 2 34 is fixed with running wheels 35 at both ends, and the running wheels 35 and the connecting shaft 2 34 rotate synchronously in the same direction, thereby realizing the travel of the trolley.
