Detailed Description

Referring to fig. 1, the present invention discloses a shuttle car 3 for turning on a rack rail 1 having a curved track. The shelf rail 1 comprises two linear rails 11 and an arc rail 12 connecting the two linear rails 11. The bins 2 are arranged side by side in at least one row and are arranged between two sections of linear rails 11, and the feed and discharge ports of the bins 2 face one of the linear rails.

In order to cooperate with the stable turning operation on the arc-shaped rail 12, please refer to fig. 2 to 6, the utility model provides a shuttle 3 comprises a frame 31, a bin bearing belt conveyor 32 on the frame 31, and wheels on both sides of the frame 31. Wherein the wheels comprise a steering wheel 33 and a driving wheel 34. The wheels are matched with the goods shelf rail 1 and run on the goods shelf rail 1. At least two steering wheels 33 are arranged on one side surface of the frame, and the side surface of the frame 31 is also provided with a rotating joint 311 and a guide shaft 312 extending downwards from the top end of the frame 31. An upper bearing hole 313 for the guide shaft 312 to insert is arranged above the rotary joint 311, and a bearing 314 matched with the guide shaft 312 is arranged in the upper bearing hole 313. The rotary joint 311 rotates around the guide shaft 312, a side bearing hole into which the steering wheel shaft 331 is inserted is formed on the outer side of the rotary joint 311, and a bearing 315 engaged with the steering wheel shaft 331 is formed in the side bearing hole. And the shuttle is driven to travel by the drive wheel 34. The other side of the frame 31 is provided with at least one driving wheel 34 (if the driving wheel 34 is provided, the driving wheel 34 and the two steering wheels 33 form a triangular arrangement to stabilize the center of gravity of the shuttle car). the shaft of the driving wheel 34 is directly connected to the other side of the frame 31, and the frame 31 is internally provided with a motor (not shown) for driving the driving wheel 34 to rotate. In the present embodiment, the drive pulley 34 does not have a function of steering, but only has a function of driving the shuttle vehicle to travel. The steering wheel 33 can make a turning angle with respect to the driving wheel 34 with the rotational degree of freedom of the rotational joint 311 to make the shuttle car 3 turn. Meanwhile, the rotational freedom degree of the rotary joint 311 is high, so that the shuttle car has low requirement on the turning radius, and the turning of the goods shelf track can adapt to various irregular storage spaces, such as a conventional arc or S shape, and the adaptability of the goods shelf assembly is improved. Meanwhile, one driving wheel 34 and two steering wheels 33 form a triangular arrangement, the driving wheel 34 travels on an inner side rail when traveling on a rail, and the steering wheels 33 travel on an outer side rail, so that the steering wheel is convenient to turn when the turning radius is small.

The belt moving direction of the belt conveying device 32 on the shuttle car is perpendicular to the extending direction of the linear track 11, that is, when the shuttle car runs on the linear track 11, the conveying direction of the belt conveying device 32 can face the material inlet and outlet of the material box 2 so as to facilitate the taking and placing of goods. The belt conveyor 32 comprises two parallel belts. In the present embodiment, the two steering wheels 33 are respectively located at two sides of the belt conveyor 32 to avoid interference with the taking and placing of the goods.

In a further improvement of the shuttle car, the turning joint 311 extends to both sides of each steering wheel 33 to form an arm 317, and a guide wheel 318 is mounted at the front end of the arm 317. The guide wheels 318 are inserted into the front ends of the arm parts 317 from the top down or from the bottom up, and the guide wheels 318 of the arm parts on both sides are divided to be located on both sides of the steering wheel 33. When the shuttle runs on the track, the guide wheels 318 contact with the side wall of the track to guide the shuttle to move, and when the shuttle runs on the arc track 12, the guide shuttle rotates so that the steering wheels correspondingly rotate to the arc track 12 through the rotation of the rotating joints 311 to realize the curve running of the shuttle. The shuttle car can run more stably on the arc track 12, and goods are not easy to shift or fall off.

The utility model discloses the method and the way of realizing this technical scheme are many specifically, above only the preferred embodiment of the utility model. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention. All the components not specified in the present embodiment can be realized by the prior art.
