Background

With the development of warehousing technology, the handling equipment such as the shuttle car gradually replaces the mode that a forklift drives into the goods shelf to store and take goods. The reason for this is that traditional fork truck is bulky, reserves very big space for fork truck between the goods shelves, and when accomplishing these tasks by the shuttle, can effectively reduce the interval between the goods shelves, realizes very high storage space utilization.

Conventional handling equipment (shuttle) is wheeled in at least two directions (e.g., orthogonal directions) on a track and jacking is accomplished by two different mechanisms, resulting in high equipment height and heavy weight. The carrying equipment needs a plurality of mechanisms capable of completing driving, reversing and jacking actions, and also needs components such as a power supply, a sensor, a controller and the like, so that the requirement on the reasonable arrangement of the self space of the shuttle car is extremely high.

The main frame body 1 and the lifting frame body can be a shell or a frame made of metal or plastic. The first walking driving device is installed on the main frame body 1, the first rotating wheels 11 can be multiple, the first rotating wheels 11 are installed on the main frame body 1 and are respectively connected and fixed with two ends of the first walking driving device, and the first walking driving device drives the first rotating wheels 11 to rotate so as to drive the main frame body 1 to walk on the first rail. The second walking driving device is arranged on the main frame body 1 and is distributed in a staggered way with the first walking driving device without mutual influence. The same first lifting mechanisms are arranged in two numbers, are respectively positioned at two sides of the second walking driving device and are symmetrically distributed about the main frame body. The two first lifting mechanisms are respectively connected with the second walking driving device, one end of each first lifting mechanism is provided with the second walking driving device, and the lifting frame body is fixedly connected with the first lifting mechanisms so as to drive the lifting frame body to move.

The second driving motor 3 rotates the fourth rotating shaft 35, and since the third gear 33 is engaged with the fourth gear 34, the fourth gear 34 mounted on the fourth rotating shaft 35 rotates the third gear 33, thereby rotating the third rotating shaft 31. The fourth gear 34 drives the third gear 33 to rotate, so that the power transmitted from the fourth rotating shaft 35 to the third rotating shaft 31 is more stable, and the power output is smooth.

Alternatively, in the present embodiment, the surface of the third gear 33 is provided with a smooth curved surface. The surface of the third gear 33 is constituted by a curved surface and a rack. The occupied area of the rack and the occupied area of the curved surface constitute the entire surface of the third gear 33. The curved surface is provided on the surface of the third gear 33 to prevent the first cam 4 from rotating excessively due to interference fit during operation. For example, the length of the curved surface of the third gear 33 is defined by the distance from the protruding end of the first cam 4 or the second cam 52 to the farthest end, and the first cam 4 and the second cam 52 are engaged with the surface of the third gear 33 during the rotation.

In the present invention, unless otherwise explicitly specified or limited, the first feature "on" or "under" the second feature may be directly contacting the first feature and the second feature or indirectly contacting the first feature and the second feature through an intermediate.

Also, a first feature "on," "above," and "over" a second feature may mean that the first feature is directly above or obliquely above the second feature, or that only the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lower level than the second feature.

In the description herein, reference to the description of the term "one embodiment," "some embodiments," "an example," "a specific example" or "some examples," or the like, means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the utility model.
