[0002] In a dense storage scenario, the shelves or floors are relatively high, and the inbound and outbound positions are generally on the ground floor. At this time, a four-way shuttle is required to go to the high-rise transfer elevator and each floor of the upper layer of the shelf or floor to pick up and place goods, so as to realize the outbound or inbound operation of the goods on the high-rise storage location.

[0003] Publication No. CN112978181A discloses a four-way shuttle, including: a controller; a sensor electrically connected to the controller; a hydraulic pump assembly including a hydraulic pump drive motor electrically connected to the controller; a hydraulic valve assembly connected to the hydraulic pump assembly; a reversing hydraulic cylinder connected to the hydraulic valve assembly; a reversing bracket mechanically connected to the plunger rod of the reversing hydraulic cylinder; a traveling drive motor electrically connected to the controller; a speed reducer mechanically connected to the traveling drive motor, having a first drive component and a second drive component; a sub-vehicle direction traveling drive assembly mechanically connected to the first drive component; and a mother-vehicle direction traveling drive assembly mechanically connected to the second drive component. The four-way shuttle provided by the present disclosure is provided with a hydraulic reversing and lifting device, which reduces the intermediate transmission link, has a lower failure rate, is more convenient for installation and maintenance, and greatly reduces the running noise of the four-way shuttle. However, the following problems still exist in the actual use process of this patent:

[0004] This four-way shuttle realizes the effect of driving the reversing bracket to lift by the reversing hydraulic cylinder, so as to realize the reversing function of the four-way shuttle. However, due to reasons such as network communication signals and software program loopholes, problems occur in the lifting of the hydraulic cylinder, resulting in the phenomenon that the reversing hydraulic cylinder does not lift synchronously. And in the prior art, the looseness caused by the chain stretching and the inaccurate starting and stopping of the wheels brought by the chain drive are likely to cause the phenomenon of uneven load on the mechanism when the four-way shuttle reverses, resulting in falling or deviation, thus causing economic losses and personal injury accidents. Therefore, the practicability of the four-way shuttle is poor.
