Detailed implementation manners

[0043] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0044] The following will be described in conjunction with Figures 1-7 the track docking safety device for shuttle car layer change of the present utility model.

[0045] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the embodiment of the present utility model aims to provide a track docking safety device for shuttle car layer change, including a shelf side track 1, a blocking mechanism 2 and a telescopic track 4.

[0046] The blocking mechanism 2 is rotatably arranged on the side track 1 of the shelf; the natural state of the blocking mechanism 2 is a normally closed state, so as to prevent the shuttle vehicle from straying into an unprepared track or accidentally falling during the layer-changing process. The blocking mechanism 2 is in a normally closed state in its natural state, that is, without external action, the blocking mechanism will block the passage of the shuttle vehicle.

[0047] The telescopic track 4 is arranged on the layer-changing elevator and can move up and down with the elevator to dock with different side tracks 1 of the shelf. The telescopic track 4 is configured with a track driving mechanism for controlling its extension or retraction. The telescopic track 4 is used to extend when its horizontal height is lifted to be flush with the side track 1 of the shelf; and under the action of the telescopic track 4, the blocking mechanism 2 is switched from the normally closed state to the open state.

[0048] The track docking safety device for shuttle vehicle layer-changing provided by the present utility model, when the horizontal height of the telescopic track 4 is lifted to be flush with the side track 1 of the shelf, docks with the side track 1 of the shelf through an extension action to form a continuous driving path. During the docking process, the blocking mechanism 2 is triggered by physical contact, so that it is switched from the normally closed state to the open state, allowing the shuttle vehicle to pass. Through the normally closed design of the blocking mechanism 2 and the linkage control of the telescopic track 4, the accidental movement of the shuttle vehicle 3 during the layer-changing process is effectively prevented, and the operation safety is improved.

[0049] See again Figure 3 As shown, in a feasible embodiment of the present utility model, an alignment mechanism 5 is further included. The alignment mechanism 5 is used to detect whether the telescopic track 4 is lifted to the target height, and the target height is flush with the side track 1 of the shelf. Through the setting of the alignment mechanism 5, the docking success efficiency of the telescopic track 4 and the side track 1 of the shelf is improved, ensuring the smooth docking of the telescopic track 4 and the side track 1 of the shelf and avoiding misalignment; at the same time, the rapid and accurate docking process shortens the layer-changing operation time and improves the work efficiency. In addition, the problem that the elevator cannot be corrected when it is lifted in place and the telescopic track 4 causes impact damage to the side docking mechanism of the shelf when it extends in the prior art is solved.

[0050] Furthermore, the alignment mechanism 5 includes a position detection induction sheet 51 and a pair of first photoelectric sensors 52. The position detection induction sheet 51 is arranged at the bottom of the side track 1 of the shelf; a pair of first photoelectric sensors 52 are arranged at the bottom of the telescopic track 4; after the elevator is lifted in place, in the horizontal direction, the pair of first photoelectric sensors 52 are respectively aligned with the top side and the bottom side of the position detection induction sheet 51. When both of the pair of first photoelectric sensors 52 sense, it proves that the telescopic track 4 and the side track 1 of the shelf are aligned, and the telescopic track 4 can extend and dock; if only one of the first photoelectric sensors 52 senses, it proves that it is not completely aligned, and it is fed back to the elevator for fine adjustment up and down until it is aligned.

[0051] See again Figure 4As shown, in a feasible embodiment of the utility model, a push plate 6 is provided at the bottom of the telescopic track 4, and the blocking mechanism 2 includes a rotating shaft 21, a blocking block 22, a swing arm 23 and a reset member 24. The rotating shaft 21 is rotatably arranged on the shelf side track 1, and both ends of the rotating shaft 21 extend outside the shelf side track 1; the blocking blocks 22 are arranged in pairs, and the blocking blocks 22 are all arranged on the rotating shaft 21 and located on the inner side of the shelf side track 1; the swing arm 23 is connected to the rotating shaft 21, and the swing arm 23 is located on the outer side of the shelf side track 1. During the extension process of the telescopic track 4, the push plate 6 can push the swing arm 23 to swing, so that the blocking block 22 rotates counterclockwise and switches from the normally closed state to the open state.

[0052] When the telescopic track 4 is docked with the shelf side track 1, the push plate 6 contacts the swing arm 23, thereby pushing the swing arm 23 to rotate counterclockwise, and the swing arm 23 is connected to the rotating shaft 21, and then the rotating shaft 21 and the swing arm 23 rotate synchronously, and the blocking block 22 rotates from the initial upright state to the horizontal state, that is, after the track docking is successful, the blocking block 22 is mechanically linked and automatically opened to ensure traffic safety.

[0053] In addition, the blocking mechanism 2 includes a reset member 24, one end of which is connected to the swing arm 23, and the other end is connected to the side wall of the shelf side track 1; in the natural state, the pulling force of the reset member 24 acts on the swing arm 23, causing the blocking block 22 to rotate clockwise, and the rotating shaft 21 of the shelf side track 1 is limited, and is upright at 90 degrees to the track surface of the shelf side track 1, thereby blocking the shuttle vehicle from passing. When the elevator is not in place, it can effectively prevent the shuttle vehicle from rushing out of the shelf side track 1.

[0054] More specifically, the reset member 24 may be a tension spring or a torsion spring.

[0055] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in a feasible embodiment of the present utility model, the blocking mechanism 2 also includes a balance wheel 25, which is rotatably arranged on the swing arm 23, and the balance wheel 25 is pushed by the push plate 6. In the initial state, when the shuttle 3 is ready to change layers, the balance wheel 25 is in a blocking position, that is, its position or shape will prevent the shuttle 3 from passing through a specific area of the shelf side track 1. When the telescopic track 4 is lifted to the target height and is ready to dock with the shelf side track 1, the push plate 6 moves with the telescopic track 4 until it contacts the balance wheel 25. Under the push of the push plate 6, the balance wheel 25 rotates around the axis of the swing arm 23, thereby changing its position or shape so that it no longer blocks the passage path of the shuttle 3. The blocking mechanism 2 design including the balance wheel 25 provides a more flexible and reliable blocking and unlocking mechanism for the track docking safety device for the shuttle changing layers.

[0056] like Figure 4As shown, in a feasible embodiment of the present utility model, the blocking mechanism 2 further includes a reset member tensioning plate 26. The reset member tensioning plate 26 is disposed on one side of the shelf side rail 1, and a plurality of reset member connection holes 27 are provided on the reset member tensioning plate 26. It provides an installation and fixing point for the reset member 24, ensuring that the reset member 24 can be stably connected to the blocking mechanism 2 and providing sufficient elastic force or tensile force to reset the blocking mechanism 2 when needed. When the push plate 6 pushes the pendulum wheel 25 to rotate, the pendulum arm 23 moves accordingly. At this time, the reset member (such as a spring) is compressed or stretched and stores energy. After the pendulum wheel 25 rotates in place, the shuttle car 3 can pass safely. After the shuttle car 3 passes or when the system issues a reset signal, the reset member 24 releases the stored energy, pushing the pendulum arm 23 and the pendulum wheel 25 to rotate in the reverse direction back to the initial blocking position.

[0057] Refer again to Figure 2 As shown, in a feasible embodiment of the present utility model, it further includes a positioning mechanism 7. The positioning mechanism 7 includes a first mounting seat 71, a second mounting seat 73, and a positioning pin 74. The first mounting seat 71 is disposed on the outer wall of the shelf side rail 1, and a positioning hole 72 is provided on the first mounting seat 71; the second mounting seat 73 is disposed on the outer wall of the telescopic rail 4; the positioning pin 74 is disposed on the second mounting seat 73, and the positioning pin 74 is correspondingly disposed with the positioning hole 72. After the docking is completed, the shuttle car 3 can enter and exit the stereoscopic warehouse through the shelf side rail 1 and the telescopic rail 4 to the elevator for layer change. When the shuttle car 3 passes through the rail docking position, due to the positioning of the positioning pin 74, even if it is a long cantilever, the docking position of the telescopic rail 4 will not sink or horizontally shift, ensuring that the shuttle car can pass through the docking position smoothly, at high speed, and safely.

[0058] In a feasible embodiment of the present utility model, one end of the positioning pin 74 facing the positioning hole 72 is set to be conical, so that the docking is simple, efficient, and stable. Using a large cone angle circular pin for direct positioning can ensure multi-directional calibration and the rigidity of the docking part.

[0059] In a feasible embodiment of the present utility model, it further includes a position sensing piece 8. The position sensing piece 8 is disposed on the shelf side rail 1, and when the positioning pin 74 is in place, the position sensing piece 8 corresponds to the first photoelectric sensor 52. It corrects the controllable deviations of the rail in the horizontal, vertical, and bending and torsion directions. When the conical positioning pin 74 is completely in place, the position sensing piece 8 and the first photoelectric sensor 52 are docked, completing the docking of the shelf side rail 1 and the elevator telescopic rail 4.

[0060] For the rail docking safety device for shuttle car layer change provided by the present utility model, when the elevator is lifting, the telescopic rail 4 is in an undocked state and can be lifted normally away from the shelf side rail 1.

[0061] When the hoist is positioned at the arrival floor, the telescopic track 4 can switch to the docking state. By extending the telescopic track 4 through the driving component, the telescopic track 4 can be docked. The push plate 6 acts on the swing wheel 25, and through the swing arm 23 and the rotating shaft 21, the blocking block 22 can be rotated to open the block. The guide of the pin and the tapered pin hole must be within a certain range, and the track docking is successful; it has the ability of vertical, horizontal and bending-torsion deviation correction, and has the functions of in-place and detachment detection; it has the rigidity to maintain the sinking and horizontal offset correction of the track docking point.

[0062] The blocking block 22 is directly driven by the swing arm 23, without a grooved shaft, the transmission is simplified, and it is the return of the return part 24, in the normally closed state to ensure safety. The alignment detection is realized through the alignment mechanism 5, which can ensure that the docking position of the telescopic track 4 is within the normal error range, making the system more controllable. The docking is carried out by using the large cone angle positioning pin 74, which makes the structure of the positioning mechanism 7 simple and firm, with strong deviation correction ability and a controllable process.

[0063] In a second aspect embodiment of the present invention, there is provided a stereoscopic warehouse, including the track docking safety device for the shuttle car to change floors as described in any one of the above embodiments.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
