The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] This embodiment provides a column support device and a stacker crane. For example... Figure 1 As shown, the stacker crane includes a lifting device 10, a ground rail device 20, and a column device provided in this embodiment. The ground rail device 20 is parallel to the horizontal direction, and the column device is parallel to the vertical direction. The column device is adjustablely positioned on the ground rail device 20, and the lifting device 10 is adjustablely connected between the two column devices 100. In this embodiment, through the above-described configuration, the position of the lifting device 10 can be adjusted in both the horizontal and vertical directions to facilitate the loading and unloading of goods on the shelf.

[0050] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The column device provided in this embodiment includes two column mechanisms 100 arranged at intervals between each other. Each column mechanism 100 is arranged parallel to the vertical direction. Each column mechanism 100 includes multiple splicing segments 110 connected sequentially along its extension direction. The multiple splicing segments 110 are connected by a splicing structure. The roller assembly of the lifting device 10 can roll along the extension direction of the multiple splicing segments 110, that is, the multiple splicing segments 110 can provide guidance for the lifting action of the lifting device 10. By setting the body of the column mechanism 100 in the form of multiple splicing segments, the length of the column mechanism 100 can be shortened during transportation, which facilitates the transportation of the column mechanism 100. It also facilitates the splicing of the column mechanism 100 after it enters the factory, and allows for flexible selection of the overall height of the column mechanism 100, improving the flexibility of assembly.

[0051] Specifically, the column mechanism 100 also includes a column guide rail 120. The column guide rail 120 is connected to the sides of multiple splicing sections 110. The stacker crane's lifting device 10 is movably connected between two column mechanisms 100 and connected to the column guide rail 120. The column guide rail 120 has a T-shaped cross-section. The safety clamp of the lifting device 10 is reliably and slidably connected to the column guide rail 120, thereby providing auxiliary guidance for the lifting process of the lifting device 10 and improving its stability and safety. Through the aforementioned column guide rail 120, in addition to providing auxiliary guidance for the lifting device 10, the integrity between the sequentially spliced ​​sections is enhanced, improving the structural reliability and integrity of the column mechanism and ensuring its stable support.

[0052] Continue to refer to Figure 2 ,、 Figure 5 and Figure 6 The splicing structure also includes a positioning pin 130. A connecting hole 114 is provided at the geometric center of the opposite ends of the two splicing segments 110. The positioning pin 130 is inserted into the connecting hole 114 at the opposite ends of the two splicing segments 110 to position the two splicing segments 110.

[0053] Specifically, refer to Figure 2 , Figure 5 and Figure 6 The splicing structure also includes connecting wing plates 111. The side edges of the opposite ends of the two splicing segments 110 are respectively provided with the aforementioned connecting wing plates 111. The two connecting wing plates 111 are mated together and reliably fixedly connected by multiple connecting bolts.

[0054] Preferably, in order to improve the structural reliability of the connecting wing plate 111 at the end of the splicing section 110, in this embodiment, a plurality of first reinforcing members 113 are provided at intervals on the connecting wing plate 111. The first reinforcing member 113 is specifically a plate-shaped structure, and its two adjacent side portions are respectively connected to the side portions of the connecting wing plate 111 and the splicing section 110.

[0055] More specifically, such as Figure 2 As shown, a clearance groove 112 is provided on one side of the connecting wing plate 111. The clearance groove 112 is configured to avoid the lifting device 10. The lifting device 10 specifically moves up and down between two column mechanisms 100, and the clearance groove 112 can avoid special structures such as sensors set on the side of the lifting device 10, so as to prevent the connecting wing plate 111 from interfering with the lifting device 10.

[0056] Continue to refer to Figures 1-4The column assembly also includes a top speed limiting sensor 210, which is disposed on the side of the top end of the column mechanism 100. In this embodiment, the top speed limiting sensor 210 is specifically in the form of a slide rail, extending along the length of the column mechanism 100. The top speed limiting sensor 210 is communicatively connected to a first limit switch (not shown) on the lifting device 10. When the first limit switch senses the top speed limiting sensor 210, the lifting device 10 can reduce its upward movement speed along the column mechanism 100, preventing the lifting device 10 from going out of control.

[0057] Specifically, the column assembly also includes a bottom speed limiting sensor 310, which is disposed on the side of the bottom end of the column mechanism 100. In this embodiment, the bottom speed limiting sensor 310 is specifically in the form of a slide rail, extending along the length of the column mechanism 100. The bottom speed limiting sensor 310 is communicatively connected to a second limit switch (not shown) on the lifting device 10. When the second limit switch senses the bottom speed limiting sensor 310, the lifting device 10 can reduce its downward movement speed along the column mechanism 100.

[0058] More specifically, the column assembly also includes a top limit sensor 220. The top limit sensor 220 has a plate-like structure and is disposed on the side of the top of the column mechanism 100. Its length is less than the length of the top speed limit sensor 210, and it is disposed side-by-side at the end of the top speed limit sensor 210 away from the bottom of the column mechanism 100. The top limit sensor 220 is communicatively connected to the first limit switch of the lifting device 10. When the first limit switch senses the top limit sensor 220, the lifting device 10 can stop its upward movement along the column mechanism 100.

[0059] More specifically, the column assembly also includes a bottom limiting sensor 320, which is disposed on the side of the bottom end of the column mechanism 100. Its length is less than that of the bottom speed limiting sensor 310, and it is disposed side-by-side at the end of the bottom speed limiting sensor 310 away from the top of the column mechanism 100. The bottom limiting sensor 320 is communicatively connected to a second limit switch of the lifting device 10. When the second limit switch senses the bottom limiting sensor 320, the lifting device 10 can stop its downward movement along the column mechanism 100.

[0060] In some embodiments, the top speed limit sensor 210 and the top limit sensor 220 are mounted on one column mechanism 100, and the bottom speed limit sensor 310 and the bottom limit sensor 320 are mounted on another column mechanism 100.

[0061] Reference Figure 1 , Figure 6 and Figure 7 The column assembly also includes a cable chain 500. The cable chain 500 connects the column mechanism 100 and the lifting device 10, and the power supply wires of the lifting device 10 are threaded through the cable chain 500. The cable chain 500 can organize the power supply wires of the lifting device 10, preventing problems such as tangling of the power supply wires during the lifting process.

[0062] Specifically, refer to Figure 1 The cable chain 500 can be mounted on only one column mechanism 100. A cable chain connecting seat 140 is provided on the side of the column mechanism 100 away from the lifting device 10, and the end of the cable chain 500 is fixedly connected to the cable chain connecting seat 140. The cable chain connecting seat 140 is specifically a plate-shaped structure, and a second reinforcing member 141 is also provided on it. The second reinforcing member 141 is specifically a right-angled triangular plate-shaped structure, with its two adjacent right-angled sides respectively connected to the cable chain connecting seat 140 and the side of the column mechanism 100, such as... Figure 7 As shown, this ensures the reliability of the cable chain connector 140 installation.

[0063] To be more specific, refer to Figure 6 The column mechanism 100 is also equipped with multiple cable chain limiting members 150. The multiple cable chain limiting members 150 are spaced apart along the length direction of the column mechanism 100, and the outer side of the cable chain 500 abuts against the cable chain limiting member 150. The cable chain limiting members 150 ensure the stability of the cable chain 500 when it moves with the lifting device 10.

[0064] Reference Figure 1 , Figure 3 and Figure 8 The column assembly also includes a safety auxiliary mechanism 400. The safety auxiliary mechanism 400 includes a mounting base 410, a pin 420, and a set of inductive switches. The mounting base 410 includes an insertion part 411 and multiple connecting parts 412. In this embodiment, there are two connecting parts 412, which are respectively disposed on opposite sides of the insertion part 411 and can be connected to the column mechanism 100 using bolts or other connecting components, thereby fixing the insertion part 411 to the column mechanism 100.

[0065] Specifically, the insertion part 411 has a first insertion channel (not shown) in a direction parallel to the column mechanism 100, and a second insertion channel 413 in a direction perpendicular to the column mechanism 100. The pin 420 can pass through the first insertion channel or the second insertion channel 413. That is, the pin 420 can be inserted into the insertion part 411 in a direction parallel to the column mechanism 100 or in a direction perpendicular to the column mechanism 100. The inductive switch group is disposed on the insertion part 411 and is communicatively connected to the control device of the stacker crane. When the inductive switch group senses that the pin 420 is parallel to the column mechanism 100, the control device controls the lifting device 10 to stop. When the inductive switch group senses that the pin 420 is perpendicular to the column mechanism 100, the control device can control the lifting device 10 to operate.

[0066] More specifically, the inductive switch group includes a first inductive switch 440 and a second inductive switch 450. Both the first and second inductive switches 440 are mounted on the insertion part 411, with the first inductive switch 440 located on the opening path of the first insertion channel and the second inductive switch 450 located on the opening path of the second insertion channel 413. When the pin 420 is inserted into the first insertion channel, the first inductive switch 440 is activated and sends a signal to the control device. The control device then puts the stacker crane into operation, and the lifting device 10 can then perform normal lifting and lowering. When the pin 420 is inserted into the second insertion channel 413, the second inductive switch 450 is activated and sends a signal to the control device. The control device then puts the stacker crane into a stopped state, and the lifting device 10 cannot perform normal lifting and lowering to ensure the safety of maintenance personnel when repairing the stacker crane.

[0067] More specifically, the safety auxiliary mechanism 400 also includes a locking member 430. The locking member 430 is detachably installed in the insertion portion 411 and can be rotated into the insertion portion 411 to lock the pin 420, or rotated to unlock the pin 420. The locking member 430 ensures the reliability of the pin 420's installation in the insertion portion 411 and prevents the pin 420 from falling out. In this embodiment, the locking member 430 can be a stud structure with a five-star handle.
