Description
Technical Field
[0001] The present application relates to a driving box for a lifting mechanism of a four-way vehicle, belonging to the technical field of intelligent equipment for warehousing and logistics. Background Art
[0002] Compared with ordinary stereoscopic warehouses, the land utilization rate and space utilization rate of intensive storage can be increased by about 20%~100%, while the operating efficiency can be increased by 20%, the operating energy consumption can be reduced by 30%, and the unit investment cost can be saved by about 10%. Therefore, the intensive storage system has received more and more attention from the industry, and its market development prospects are broad. As an important handling equipment for intensive storage, the intelligent pallet-type four-way shuttle car, referred to as the four-way car, is an intelligent track-guided automatic reversing and track-changing handling equipment. Under the control of the electronic control system, it accurately locates each input and output station through digital technologies such as encoders, RFID, and photoelectric sensors, and is equipped with an intelligent scheduling system. After receiving the material, it automatically shuttles back and forth. The four-way car does not require human operation, has a fast running speed, and a high degree of intelligence. It is suitable for various logistics storage systems and can promote the rapid realization of automatic flat transportation of unit materials.
[0003] Existing four-way vehicles mostly use a lifting mechanism to lift cargo and change the direction of the vehicle body. The existing lifting mechanism drives the rigid chain 21 through the driving sprocket 20 to lift the lifting plate 30, and a sliding block is connected to the outside of the lifting plate to lift and change the direction of the channel wheel. Figure 1-Figure 2As shown. This type of lifting mechanism has a vehicle body restriction between the lifting plate 30 and the sliding block on the outside of the vehicle body. The lifting plate will have a spatial conflict with the vehicle body during the lifting or lowering process. Therefore, the radial height of the driving box of this type of lifting mechanism needs to be set to a higher size to ensure that the lifting plate has a sufficient lifting stroke, and at the same time, there will be no spatial conflict with the vehicle body due to the small radial height. However, this will cause the driving box to be larger in size, which is not conducive to the design requirements of the four-way vehicle for miniaturization. On the other hand, the existing four-way vehicle adopts the method of installing the lifting mechanism on the opposite sides of the vehicle body, and installing channel steels on the top of the lifting plates on both sides as load-bearing plates to carry the cargo load. However, in the process of lifting the cargo, due to the long axial distance of the channel steel, when carrying cargo with a large load, there is unstable movement during the lifting or lowering of the channel steel, which will cause the cargo to shake or even fall. In addition, the rigid chain installed in the driving box of the existing jacking mechanism is in a moving state and has daily wear. In the prior art, lubricating medium is added to the driving box for lubrication to reduce wear, but the lubricating medium will be brought out or squeezed to the inner corner of the box with the movement of the chain, resulting in insufficient lubrication, and the lubricating medium needs to be added frequently, which affects the use efficiency. Therefore, a driving box of a jacking mechanism is urgently needed to solve the problem that the driving box of the existing jacking mechanism is large in size, resulting in a large installation space, and the existing jacking plate drives the channel steel to move unsteadily, resulting in low use efficiency.

[0027] The box body of this embodiment is provided with two parallel U-shaped guide grooves 31 inside, and the cavity between the two U-shaped guide grooves 31 forms a chain track. The box body of this embodiment includes a first sub-box 9 and a second sub-box 10; the first sub-box 9 and the second sub-box 10 are relatively installed as a whole, and the relative inner sides of the two sub-boxes are respectively provided with U-shaped guide grooves 31; when the first sub-box and the second sub-box are installed as a whole, the vertical guide grooves on both sides of the U-shaped guide groove extend radially to the outside of the box body respectively, forming two openings; the driving sprocket 4 is rotatably installed in the middle of the U-shaped guide groove. Among them, the side edge of the outer box body of the box body located at the vertical guide groove position of the U-shaped guide groove away from the lifting plate side extends outward in the horizontal direction to form a second slideway 33, and the outer box body of the vertical guide groove located on the lifting plate side is recessed inward toward the oil tank plate direction to form a first groove. A driving shaft 16 is provided on both sides of the driving sprocket 4; bearing mounting holes are respectively opened at positions corresponding to the driving shaft in the first sub-box 9 and the second sub-box 10; the driving shaft is rotatably mounted in the bearing mounting hole by installing bearings on the shaft body, and the end of the driving shaft extends to the outside of the box to constitute a driving end.
[0028] The rigid chain of this embodiment includes a plurality of chain plates 5 and chain links 8, each of which is rotatably mounted with a pin shaft 6. The rigid chain 2 is connected as a whole in sequence by installing chain links 8 between adjacent pin shafts of two adjacent chain plates 5, and rollers 11 are rotatably mounted on both side ends of the pin shafts. The rigid chain 2 is installed in the U-shaped guide groove 31 through the rollers 11 on both sides and is slidably installed on the chain track.
[0029] In addition, an oil groove plate 17 is installed along the chain track between the two openings inside the box body of this embodiment, and the oil groove plate forms a lubricating oil groove in the cavity of the chain track on the side of the driving sprocket. Among them, the radial height of the oil groove plate on the lifting plate side in the U-shaped guide groove of the box body is consistent with the height of the driving shaft of the driving sprocket.
[0030] Working principle: When the four-way vehicle runs to the main channel, the handling robot is facing the main channel. At this time, the main channel wheel contacts the main channel track of the shelf, allowing the four-way vehicle to pass through the main channel. At this time, the functions that can be realized include running on the main channel, running with goods on the main channel, entering the elevator to carry goods or overall layer change.
[0031] When the four-way vehicle enters the secondary channel from the main channel to transport goods, the wheels need to be reversed at the intersection. At this time, the vehicle stops, the lifting mechanism of this embodiment starts to operate, and the driving chain machine drives the driving shaft of the driving sprocket to drive the rigid chain to rotate. Specifically, the driving sprocket drives the rigid chain to move toward the vertical guide groove on the lifting plate side of the chain track, and then drives the sliding seat to move radially upward, that is, the vehicle body moves downward as a whole, thereby driving the secondary channel wheel to move toward the secondary track until it contacts the secondary track. As the main channel wheel assembly moves up, the handling robot is facing the secondary channel direction. At this time, the main channel wheel is separated from the main channel, and the secondary channel wheel contacts the secondary track. Then the secondary channel wheel operates to realize the operation of the four-way vehicle on the secondary channel and find the goods to be transported.
[0032] When the four-way vehicle finds the goods to be transported in the secondary channel, the vehicle stops, and the lifting mechanism starts, driving the chain machine to drive the drive shaft of the driving sprocket to continue to drive the rigid chain to rotate, driving the sliding seat to continue to move radially upward, so that the main channel wheel assembly continues to move upward, and the lifting plate on the upper part of the sliding seat lifts the pallet and leaves the shelf. Then the secondary channel wheel runs, and the four-way vehicle moves the goods to the intersection of the main and secondary channels according to the scheduling requirements.
[0033] When the four-way vehicle moves the goods to the intersection of the main and secondary channels, the vehicle stops, and the lifting mechanism of this embodiment is driven in reverse by the driving chain machine, and the driving sprocket drives the rigid chain to move toward the vertical guide groove on the side of the lifting plate away from the chain track, thereby driving the sliding seat to move radially downward, thereby driving the main channel wheel to move downward, and when the main channel wheel moves down to the point where the goods contact the vehicle body, the main channel wheel continues to move down to the point where it contacts the main channel track, and the secondary channel wheel is separated from the secondary channel track, and the main channel wheel runs. At this time, the four-way vehicle runs with the goods to the intersection of the designated secondary channel and the main channel.
[0034] After the four-way vehicle runs with the goods to the intersection of the designated secondary channel and the main channel, the vehicle stops, the driving chain machine drives the lifting mechanism to operate, the main channel wheel continues to move upward, driving the lifting plate to lift the pallet and goods to the height of picking up; at this time, the secondary channel wheel runs, and when it reaches the designated cargo parking position, the four-way vehicle stops, and the goods are finally taken away by the picking mechanism, and the lifting mechanism is reset, completing a cargo handling. This reciprocating process realizes the outbound and inbound storage of goods and realizes the rapid storage function.
[0035] The above are only preferred embodiments of the present application and are not intended to limit the scope of implementation of the present application. That is, any equivalent changes and modifications made according to the content of the patent scope of the present application shall fall within the technical scope of the present application.
