[0027] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0028] like Figure 1 As shown, a four-way shuttle vehicle comprises a frame 1, a pair of lifting plates 4 are symmetrically arranged on the upper surface of the frame 1, and the lifting plates 4 can be extended and retracted up and down. When the goods are placed on the four-way shuttle vehicle, the lifting plates 4 rise to lift the goods. The four-way shuttle vehicle also includes transverse running wheels 2 and longitudinal running wheels 3 for it to travel on the guide rails. Auxiliary baffles are also arranged on each side of the frame 1, and a driving member is also arranged inside the frame to provide power to the auxiliary baffles 5 to complete the blocking and opening actions.

[0029] Specifically, the top plate of the frame 1 is provided with a mounting opening, such as Figure 1 The structure shown is a long strip, which is located at the edge areas on both sides of the top plate of the frame 1. The lifting plate is set in the installation opening for lifting, and there is a small gap between the lifting plate and the installation opening to reduce obstacles to the lifting process.

[0030] Furthermore, if Figures 1 to 4 As shown, it can be seen that the auxiliary baffles 5 are arranged on the four sides of the frame. As a preferred setting method, the frame can be set to a square structure, and the auxiliary baffles 5 are arranged on the four sides to enclose and form a blocking space to block the material pallet supported on the frame on all sides, thereby reducing the deviation of the material pallet during transportation and ensuring the reliability of transportation.

[0031] Regarding the setting method of the auxiliary baffle, this application will be described in two different embodiments. It can be understood that the two embodiments only differ in the structural setting method and the action method. The effect of reducing the detachment and deflection of the cargo box and the structural composition of the main body are similar.

[0032] Embodiment 1:

[0033] As a specific implementation of the present application, the driving member is an electric rotating shaft, and the top wall edge of the auxiliary baffle is provided with an arc structure to improve the blocking effect on the objects transported by the shuttle vehicle.

[0034] like Figure 2 , 3 The first embodiment of the utility model is shown. When the cargo box is placed on the four-way shuttle, the lifting plate 4 rises upward, and the electric shaft 7, which is a driving member for the auxiliary baffle 5 to complete the lifting and lowering action, also starts to work, and drives the auxiliary baffle 5 to flip by rotating clockwise. Due to the lifting of the auxiliary baffle 5, a blocking space is formed on the upper part of the four-way shuttle. When the cargo box moves on the guide rail, the auxiliary baffle 5 can limit the displacement of the cargo box on the four-way shuttle, preventing the cargo box from sliding off the four-way shuttle, blocking the operation of other shuttles, causing the transportation guide rail to be blocked, and reducing work efficiency.

[0035] Among them, Figure 2 As shown, when the auxiliary baffle 5 is driven by the electric shaft 7 to rotate to the blocking position, it should be able to block most of the area of ​​the cargo box it carries and block the entire box as much as possible, that is, when the auxiliary baffle 5 is rotated to the blocking position, the height of its top edge should be as high as possible above the height center line of the cargo box to improve the blocking effect. In addition, the driving force generated by the torque of the motor shaft should be as large as possible to provide sufficient pushing force for the material blocked by the auxiliary baffle to further improve the blocking effect.

[0036] It is understandable that the height of the goods transported in this way should not be too high, because the weight of goods that are too large and too high will also increase. During the turning and transportation process, the auxiliary baffles set around the shuttle car shelves will inevitably have insufficient blocking effect. Therefore, during use, goods with a lower discharge height should be used as much as possible, or structures such as transport material pallets should be used.

[0037] And, if Figure 2 As shown, the top wall edge of the auxiliary baffle 5 can be provided with an arc structure, and the arc structure can be used to perform a certain buckling on the top wall edge of the cargo box when the height of the auxiliary baffle 5 is higher than or equal to the height of the cargo box, thereby further improving the positioning effect.

[0038] Furthermore, the auxiliary baffle has a blocking position perpendicular to the upper surface of the frame. The blocking position referred to here is the position of the auxiliary baffle that can block the cargo box after flipping, and can further clamp the top of the cargo box whose height is lower than the auxiliary baffle, so that the side edge of the auxiliary baffle after rotation and flipping is positioned on the side edge of the cargo box.

[0039] Embodiment 2:

[0040] As a preferred embodiment of the present application, the driving member is a driving strut, and the driving strut is a hydraulic strut or an electric-controlled strut.

[0041] Specifically, Figure 4 , 5 The second embodiment of the utility model is shown, and the driving member that provides power for the auxiliary baffle 6 to rise and fall is a driving pillar 8. The driving pillar 8 is preferably a hydraulic pillar and an electric control pillar. For the convenience of description, the present application adopts an electric control pillar, and the driving member adopts the form of a driving pillar 8, which can better increase the stability of the driving member, not only making the turning and rising of the auxiliary baffle more uniform and stable, but also providing sufficient support force through the driving pillar 8 when shielding the cargo box, further reducing the phenomenon of the cargo box falling.

[0042] Among them, Figure 5 As shown, the auxiliary baffle 5 can reach the maximum height under the lifting of the driving pillar 8, and its maximum height is that the auxiliary baffle 5 is flush with the surface of the frame 1, so as to reduce the deflection of the cargo box caused by uneven height, and the setting of the auxiliary baffle 5 increases the surface area of ​​the frame 1, which can give the cargo box a larger swaying space to a certain extent. It can not only carry larger cargo boxes, but also the existence of the swaying space can reduce the situation in which the cargo box falls along the edge of the baffle during transportation due to the lack of movable gap, and can reduce the tipping phenomenon caused by one side of the cargo box detaching from the edge of the frame.

[0043] And, if Figure 4 and Figure 5 As shown, the edge of the auxiliary baffle 5 may be provided with a protrusion 6 to Figure 5For example, when the auxiliary baffle 5 is lifted by the driving support 8 to the point where the auxiliary baffle 5 is parallel to the top surface of the frame 1, the boss 51 is higher than the surface of the auxiliary baffle 5 to prevent the cargo box from falling off, and the overall length of the auxiliary baffle should be moderate and does not need to be too long, so that when the cargo box shakes and tilts, the boss 6 can play a certain blocking role, thereby reducing the occurrence of the cargo box falling off.

[0044] Furthermore, in the second embodiment, the boss 6 has a stop rib 9 protruding toward the blocking space formed by the auxiliary baffle 5, and the stop rib 9 can contact the edge of the cargo box to further improve the support effect on the cargo box and reduce deflection and falling off; in addition, for the structure in the second embodiment, the surface of the driving pillar 8 can be provided with an elastic part, which can improve the load-bearing capacity to a certain extent while reducing the shock of the carried cargo box.

[0045] As for the structure of the elastic part, it can also be arranged at the stop rib, and a flexible resin plate can be used to shrink and expand when the cargo box contacts, so as to achieve a shock-absorbing effect. Of course, a combination structure of a plastic plate and a spring can also be directly used, and arranged on the surface of the boss 6. For example, a spring is arranged on the side of the boss 6 facing the blocking space, and the spring is used to connect the plastic plate to achieve elastic buffering.

[0046] As for the elastic member on the surface of the driving support, a spring structure can also be selected, which has a simple structure and provides sufficient buffering effect.

[0047] It should be noted that for Example 1 and Example 2, technicians in this field should know that after the auxiliary baffle 5 is deployed, it should be ensured that it does not touch other structures in the lane (such as shelves, walking tracks, etc.) as much as possible to ensure the smooth operation of the shuttle vehicle.

[0048] In order to ensure that the shuttle can be transported faster when it is empty and reduce the accidental contact between the auxiliary baffle 5 and other structures in the lane, the accommodating groove for accommodating the auxiliary baffle 5 should be extended as far as possible into the frame so that the auxiliary baffle 5 after accommodating is in an inclined state, which can be as shown in FIG. Figure 1 As shown, the outer edge of the auxiliary baffle 5 is aligned with the outer edge of the accommodating cavity in the vertical direction, that is, the top of the auxiliary baffle can be completely received in the receiving groove without protruding outward, so as to reduce the collision between the boss, stop rib and other structures on the top of the auxiliary baffle and the transport channel.

[0049] It is understandable that in order to ensure the resistance and positioning of the cargo box carried by the four-way shuttle, the structure of the utility model should be set up in the form of four-sided enclosures, that is, Figure 2 , 4As shown, the same baffle structure should be provided at the relative positions of the two auxiliary baffles, so as to achieve the surrounding effect of the cargo box by the four auxiliary baffles and reduce the deflection and falling of the cargo box carried by the four-way shuttle.

[0050] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0051] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0052] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
