Description

Technical Field

[0001] The invention relates to the technical field of rail transportation, and more specifically to a high-performance ultra-thin rail shuttle vehicle. Background Art

[0002] Rail-guided shuttle, also known as rail-guided automatic guided vehicle, is a material handling equipment that runs on fixed tracks. It combines automation technology, mechatronics technology and computer technology, and can efficiently complete cargo storage and retrieval tasks. Rail-guided shuttle automatically runs on preset tracks through its own electromagnetic or optical guidance device. When receiving instructions, RGV will move to the specified position according to the set path to perform cargo storage and retrieval operations. Its core components include frame, drive wheels, follower wheels, front and rear bumpers, chain conveyors, communication systems, and various sensors. These components work together to ensure that RGV can complete tasks accurately and stably.

[0003] When the rail shuttle vehicle completes its cargo distribution task, its vehicle weight will increase significantly. This change directly leads to the drive wheels having to bear greater pressure during vehicle operation. Since the drive wheels and the chain rails rely on friction to transmit power, the increase in vehicle gravity will cause the friction to increase accordingly. Although this increase in friction ensures that the vehicle can overcome the increased resistance and continue to run, it also brings a series of problems: on the one hand, the increase in friction means that the drive wheels and the chain rails will generate more heat and wear during their contact with each other. Long-term high friction will lead to the gradual loss of the surface materials of the drive wheels and the chain rails, and may even cause deformation, cracks and other damage. These damages will not only affect the normal operation of the vehicle, but may also pose a threat to driving safety. On the other hand, as the wear of the drive wheels and the chain rails increases, the clearance between them will gradually increase, which will cause the vehicle to shake and bump during operation, further exacerbating the wear and tear of the vehicle and energy consumption.

[0004] Therefore, the present invention proposes a high-performance ultra-thin rail shuttle vehicle, so that the rail shuttle vehicle can automatically lubricate the drive wheel when loading cargo, so as to reduce the wear between the drive wheel and the chain rail, delay the service life of the equipment, and extend the maintenance cycle.

An oil pump can be installed on the return oil pipe 805 to pump the oil in the recovery chamber back to the oil storage tank 701 for reuse.

[0032] Working principle of the present invention: When the rail shuttle needs to travel along the track, the motor 5034 receives the operation command of the controller and starts, and the output shaft of the motor 5034 drives the pulley 5031 connected thereto to rotate coaxially through the coupling 5033. The two pulleys 5031 are synchronously transmitted through the synchronous belt 5032, so that the other pulley 5031, the transmission shaft 5011 and the active bevel gear 5012 connected to the left and right ends of the transmission shaft 5011 rotate coaxially, and the rotating active bevel gear 5012 drives the auxiliary bevel gear 5022 meshed with it, so that the rotating shaft 5021, the auxiliary bevel gear 5022 and the transmission gear 5023 rotate coaxially. Since the transmission gear 5023 is meshed with the chain track of the track, the rotating transmission gear 5023 can continuously cling to the chain track to transmit the driving power, so that the shuttle runs along the track and moves to the designated position according to the set path to perform the storage and retrieval operation of the goods; When the cargo pallet loaded with goods is assembled on the cargo pallet 2, the counterweight of the cargo pallet 2 increases and sinks downward. At this time, the connecting column 401 connected to the bottom wall of the cargo pallet 2 will drop synchronously, so that the limit plate 403 and the guide wheel 402 slide relatively along the surface of the connecting column 401 and compress the second spring 404, so that the guide wheel 402 is always placed in the guide rail of the track to maintain the guiding ability of the equipment. At the same time, the I-shaped piston 302 receives the gravity of the cargo on the cargo pallet 2 and compresses the liquid chamber of the buffer box 301 and the first spring 303 downward, and weakens the buffering force of the cargo pallet 2 on the vehicle body 1 during cargo distribution through the elastic expansion and contraction of the buffer component 3 and the guide component 4, thereby reducing the impact and protecting the equipment; At the same time, since the I-shaped piston 302 compresses the liquid cavity of the buffer box 301, the lubricating oil in the liquid cavity of the buffer box 301 is introduced into the inner cavity of the oil tank 601 through the tee 11, and an instantaneous high pressure is formed, so that the sealing plug 606 moves to the side of the telescopic rod 605 and detaches from the oil drain hole on the side wall of the oil tank 601. Then, the lubricating oil in the oil tank 601 flows out quickly through the oil drain hole under the action of the centrifugal tumbling of the impeller 602, and drips into the oil guide groove 607 and the transmission gear 5023 through the oil drain groove. The lubricating oil flowing into the oil guide groove 607 is not The oil-absorbing cotton 608 is continuously wetted to lubricate the transmission process of the transmission gear 5023 and the chain rail, and the lubricating oil entering the transmission gear 5023 flows to the auxiliary bevel gear 5022 and the driving bevel gear 5012 through the through hole of the bottom wall thereof, and also lubricates the transmission of the two. Finally, the overflowing lubricating oil flows back to the separation tank 802 through the through hole of the support seat 5024, the oil collecting bucket 5025 and the oil drain pipe 804 in turn, and then passes through the separation tank 802 after being filtered by the filter plate 803 and enters the recovery chamber at the bottom of the return oil tank 801 to be reused; After unloading, the I-shaped piston 302 is reset under the elastic force of the first spring 303, and then the pressure in the liquid chamber of the buffer box 301 is recovered, so that the sealing plug 606 blocks the oil drain port of the oil tank 601 again, and draws the lubricating oil in the oil tank 601 back into the inner chamber of the buffer box 301 for use in the next cycle.

[0033] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, all of which should be included under the protection of the present invention.
