Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of current collectors, in particular to a current collector device for a gravity-type shuttle vehicle. Background Art
[0002] There are two main forms of shuttle vehicles in warehousing and logistics equipment: shuttle vehicle-type in-and-out storage system and shuttle vehicle-type warehousing system. In the shuttle vehicle, the trolley runs on a fixed track in a reciprocating or looping manner to transport goods to the designated location or docking equipment. The shuttle vehicle needs to constantly change its position due to its movement, and the shuttle vehicle must be able to obtain power at any time, otherwise it will not be able to continue moving. At this time, a busbar is needed, that is, a conductor connected to the power supply is laid along the track. During the movement, the shuttle vehicle is connected to the busbar through the collector, so that the collector transmits the current on the conductor to the shuttle vehicle, thereby powering the shuttle vehicle.
[0003] Traditional shuttle bus collectors are installed with spring hard connections. When the track goes up and down, or when the track is worn and bumpy, the collector will collide with the busbar due to the influence of spring tension, causing the insulating sleeve to easily break due to the impact force, and easily increase the wear of the collector and the busbar, which is prone to poor contact. Utility Model Content
[0004] Based on this, the purpose of the present invention is to provide a current collecting device for a gravity shuttle vehicle to solve the technical problems mentioned in the above background technology.

[0006] By adopting the above technical solution, the structural mode of the current collector is changed from the previous hard connection of the spring to relying on the deadweight of the roller to adapt to the height of the sliding bus line. The roller is lifted up and down by the coordinated guidance of the linear bearing and the guide rod, thereby achieving good contact between the current collector and the sliding bus line, ensuring stable power supply for the shuttle car and better adapting to the uneven sliding line.
[0007] Furthermore, the guide rod is slidably connected to the linear bearing, and the stop plate abuts against the linear bearing.
[0008] By adopting the above technical solution, the roller can be lifted up and down by the coordinated guidance of the linear bearing and the guide rod. When the guide rod descends and is about to fall off, the stop plate will abut against the top of the linear bearing to prevent the guide rod from separating from the linear bearing.
[0009] Furthermore, the roller is rotatably connected to the wheel axle via a rotary bearing, and the rotary bearing is a sealed bearing.
[0010] By adopting the above technical solution, the friction and wear between the roller and the axle are reduced by setting the rotating bearing, thereby extending the service life of the structure, and the rotating bearing is sealed to prevent impurities from entering the rotating bearing, increasing resistance and causing difficulty in roller rotation.
[0011] Furthermore, one side of the spacer sleeve abuts against the collector seat, and the other side of the spacer sleeve abuts against the rotary bearing.
[0012] By adopting the above technical solution, the spacer is provided to avoid the left-right displacement of the rotating bearing and the roller, thereby improving the stability of the roller during operation.
[0013] Furthermore, a mounting bolt is connected between the linear bearing and the fixing seat, and the linear bearing is detachably connected to the fixing seat via the mounting bolt.
[0014] By adopting the above technical solution, the staff fits the linear bearing to the fixed seat, and then screws in the mounting bolts to fasten the linear bearing to the fixed seat.
[0015] Furthermore, a limiting bolt is connected between the stop plate and the guide rod, and the stop plate is detachably connected to the guide rod through the limiting bolt; a first cotter pin passes through one side of the guide rod, and the rod seat is detachably connected to the guide rod through the first cotter pin.
[0016] By adopting the above technical solution, the staff passes the guide rod through the linear bearing. At this time, the staff places the stop plate on the top of the guide rod and then screws in the limit bolt, thereby fastening the stop plate to the guide rod and preventing the guide rod from separating from the linear bearing.
[0017] Furthermore, a first fastening bolt is connected between the insulating sleeve and the rod seat, a second fastening bolt is connected between the insulating sleeve and the collector seat, and the insulating sleeve is detachably connected to the rod seat and the collector seat through the first fastening bolt and the second fastening bolt respectively.
[0018] By adopting the above technical solution, the staff inserts the insulating sleeve into the bottom of the rod seat and puts the collector seat on the bottom end of the insulating sleeve. At this time, the staff passes the first fastening bolt and the second fastening bolt through the insulating sleeve and tightens them, thereby completing the assembly work from the insulating sleeve and the collector seat.
[0019] Furthermore, assembly bolts are passed through both sides of the top of the collector seat, second cotter pins are passed through both sides of the outer surface of the axle, and the axle is detachably connected to the collector seat through the second cotter pins, and the spacer and the rotating bearing are detachably connected to the axle.
[0020] By adopting the above technical solution, the workers assemble the collector seat and screw in the assembly bolts to tighten the limit; then the workers pass the axle through both sides of the collector seat. While passing through the axle, the workers put the spacer and the rotating bearing on the outside of the axle. After the axle passes through both sides of the collector seat, the spacer is set to prevent the rotating bearing and roller from shifting left and right. Then the workers pass the second cotter pin through both sides of the outer surface of the axle to prevent the axle from falling off.
[0021] In summary, the present invention has the following beneficial effects:
[0022] The utility model changes the structural mode of the current collector from the previous hard connection with a spring to one that relies on the deadweight of the roller to adapt to the height of the busbar, and realizes the up and down movement of the roller through the coordinated guidance of the linear bearing and the guide rod, thereby achieving good contact between the current collector and the busbar, ensuring stable power supply for the shuttle car and better adapting to uneven busbars; the old direct-connected current collector hard connection is changed, avoiding the occurrence of insulation sleeve breakage, severe wear, poor contact with the busbar, etc. caused by large force on the current collector.
