Description

Technical Field

[0001] This invention relates to the field of stacker crane technology, specifically a single-column high-speed stacker crane. Background Technology

[0002] Single-column stacker cranes are core equipment in automated storage and retrieval systems (AS / RS) used for automatically storing and retrieving goods between high-rise racks. They use a single column as the main support structure and are suitable for light-load, high-speed, and medium-to-low-height warehousing scenarios.

[0003] Existing single-column stacker cranes mainly consist of rectangular frame columns and upper and lower crossbeams. The dimensions of the rectangular frame need to be customized based on the actual height of the factory building and the height of the shelving units. However, this customized rectangular frame has certain drawbacks in practical use. Because the shelving units in the factory are variable, the rectangular frame columns need to move directionally along pre-set tracks on the ground. If the factory height changes, the movement of the customized rectangular frame columns on the tracks is severely restricted, seriously affecting the actual application rate of the single-column stacker crane.

[0004] Therefore, this invention designs a single-column high-speed stacker to solve the above problems. Summary of the Invention

[0012] In a preferred embodiment, the present invention can be further configured as follows: studs are provided in both the bottom groove and the side groove of the fixing plate, and the plate end at the top of the base is fixedly installed on the stud in the bottom groove of the fixing plate by a nut, while a positioning plate is inserted into the side groove of the fixing plate, a buckle plate is installed in the gap between the positioning plate and the fixing plate, and two rectangular slots are provided on the inner side of the buckle plate, and the positioning plate is fixedly installed on the stud in the side groove of the fixing plate by a nut.

[0013] In a preferred embodiment, the present invention can be further configured such that: two rectangular plates are fixedly installed at the bottom of the external sliding column side slot, and the two rectangular plates are adapted to be snapped into two rectangular slots on the inner side of the buckle plate.

[0019] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0020] 1. This invention assembles a tensioning bearing mechanism on the table of an existing rotary motor, and sets an external sliding column and an internal sliding column with a splicing structure on the top of the tensioning bearing mechanism. The internal frame serves as the support carrier for the internal sliding column. When it is necessary to adapt to the height of the shelves and the size of the shelves after the change in the factory, the client runs a second motor. Finally, under the meshing linkage of two auxiliary rotating gears, the extended screw will push the ring pad and the internal sliding column to lift to a high position, thereby improving the high efficiency of the single column structure.

[0021] 2. This invention arranges a clamping plate on the outside of the load-bearing base to position and clamp the four shafts. As the first motor drives the four shafts to rotate relative to each other, multiple evenly distributed winding rollers can adjust the tension of multiple cables. With the adaptive height adjustment of the two sliding columns, the tension adjustment of the multiple evenly distributed cables can enhance the structural strength of the two sliding columns after the high-position adjustment, thereby ensuring the stability and safety of the inner sliding column and the outer sliding column after the extension is under load.

[0022] 3. This invention installs four assembly platforms arranged in a cross shape on the top of an external sliding column. These platforms are adapted to a cargo platform movably mounted on the external sliding column. After the external lifting motor is fixed to one of the assembly platforms as needed, a lifting chain connects the lifting motor to one section of the cargo platform. This adaptive height-adjustable column structure provides a convenient load-bearing carrier for assembling the stacking arm and balancing module, ensuring the dynamic balance of the hoisted goods as they ascend and descend along the column.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0041] These descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0042] The following describes, with reference to the accompanying drawings, some embodiments of a single-column high-speed stacker provided by the present invention.

[0043] Example 1:

[0044] Combination Figures 1 to 11As shown, the present invention provides a single-column high-speed stacker crane, including a tensioning and bearing mechanism 100, a climbing and pushing mechanism 200 disposed on the tensioning and bearing mechanism 100, a high-position column mechanism 300 installed outside the climbing and pushing mechanism 200, a hoisting support mechanism 400 installed on the high-position column mechanism 300, and a loading platform 500 disposed outside the high-position column mechanism 300. The tensioning and bearing mechanism 100 is mounted on the platform of an external rotary motor and is used to provide a support carrier for the climbing and pushing mechanism 200 and the high-position column mechanism 300. The climbing and pushing mechanism 200 is used to provide adjustment and support for the high-position column mechanism 300 in a high-position state. The hoisting support mechanism 400 is used to provide a support platform for the lifting motor and to provide anti-detachment protection for the extension of the high-position column mechanism 300.

[0045] The tensioning bearing mechanism 100 includes a load-bearing base 110, a base 170 on the top of the load-bearing base 110, a second housing 180 fixedly installed in the slot inside the base 170, a second motor 1801 fixedly installed inside the second housing 180, and a main auxiliary rotating gear 1802 installed on the second motor 1801.

[0046] The climbing booster mechanism 200 includes a fixed plate 210 installed on the top of the base 170. An internal frame 240 is fixedly installed inside the fixed plate 210. A top pad 2401 is installed on the top of the internal frame 240. Four vertical slots 2402 are opened inside the internal frame 240. Bearings 250 are installed inside both the internal frame 240 and the top pad 2401. An extension screw 260 is installed inside two bearings 250. A secondary auxiliary rotating gear 2601 is installed at the bottom of the extension screw 260.

[0047] The high-position column mechanism 300 includes an internal sliding column 340 with an internal frame 240 outside, and an external sliding column 310 is movably installed on the external side of the internal sliding column 340. The bottom of the internal sliding column 340 is provided with four insert plates 3403, and a ring washer 360 is provided in the middle of the four insert plates 3403. A locking bolt 3601 installed in the ring washer 360 is inserted into the insert plate 3403. The ring washer 360 is threaded on the outside of the extension screw 260. Four main rails 330 are fixedly installed on the outside of the external sliding column 310. Four auxiliary rails 350 are fixedly installed on the outside of the internal sliding column 340. A threaded section is provided on the top of the side slot of the internal sliding column 340.

[0048] The hoisting support mechanism 400 includes two first assembly platforms 410 and two second assembly platforms 420 arranged in a cross shape outside the built-in sliding column 340, and both the first assembly platforms 410 and the second assembly platforms 420 are fixed to the threaded section in the side groove of the built-in sliding column 340 by nuts.

[0049] Right-angle grooves 430 are provided on the bottom of the inner side of the first assembly platform 410 and the second assembly platform 420, and pre-installation holes are provided on the top plate sections of the first assembly platform 410 and the second assembly platform 420 to provide an effective support carrier for the external lifting motor.

[0050] The loading platform 500 is movably installed on the outside of the four main rails 330 and the four auxiliary rails 350. The loading platform 500 is composed of a rectangular frame plate and four Y-shaped brackets. The outer wall of the rectangular frame plate is welded with multiple sets of clamping plates, and the Y-shaped brackets are fixed in the two adjacent sets of clamping plates by inserting rods. The Y-shaped brackets facilitate the convenient assembly of the stacking arm and the balancing module.

[0051] Preferably, the clamping shaft support plate 1101 has four pads arranged in a cross shape at the center of its four sides, and the pads have multiple evenly distributed vertical holes inside. In actual use, the load-bearing base 110 and the clamping shaft support plate 1101 can be fixed to the table of the external rotary motor using combination bolts.

[0052] In order to improve the smoothness of rotation of the first shaft 130, the third shaft 150 and the two second shafts 140, the rod segments in the first shaft 130, the third shaft 150 and the two second shafts 140 can be movably installed in the holes inside the clamping plate 1101 through bearings, and the main auxiliary rotating gear 1802 and the auxiliary auxiliary rotating gear 2601 mesh with each other, which facilitates the adaptation and meshing of the auxiliary auxiliary rotating gear 2601;

[0053] In addition, after the top pad 2401 is inserted into the top of the built-in frame 240, it can be fixed by welding. The bottom plate end of the built-in slide column 340 is provided with a T-shaped protruding slide plate, and the T-shaped protruding slide plate is adapted to penetrate into the vertical groove 2402, which facilitates the smoothness of the built-in slide column 340 rising and falling along the inner cavity of the external slide column 310.

[0054] The second motor 1801 is started by the client. The main auxiliary gear 1802, which is controlled and rotated by the second motor 1801, will drive the secondary auxiliary gear 2601. Finally, the extended lead screw 260 will help the ring pad 360 and the built-in slide column 340 to rise and fall smoothly along the gap between the external slide column 310 and the built-in frame 240. This allows the new column structure to be adaptively adjusted according to the changes in height in the actual factory and the different structures of the shelves.

[0055] Example 2:

[0056] Combination Figure 4 and Figure 9As shown, based on Embodiment 1, a clamping shaft support plate 1101 is fixedly installed on the outside of the load-bearing base 110. A first shaft 130, a third shaft 150, and two second shafts 140 arranged in a rectangular shape are movably installed inside the clamping shaft support plate 1101. A first housing 120 is fixedly installed on one side of the clamping shaft support plate 1101. A first motor 1201 is fixedly installed inside the first housing 120. One end of the first shaft 130 is installed on the first motor 1201. The first shaft 130 and the third shaft 150 are both composed of a drive rod and a main deflection gear. The two second shafts 140 are both composed of a linkage rod, a linkage gear, and a secondary deflection gear. The two main deflection gears in the first shaft 130 and the third shaft 150 respectively mesh with the linkage gears in the two second shafts 140.

[0057] Two take-up rollers 160 are installed on the first shaft 130, the third shaft 150 and the two second shafts 140. A cable 1601 is wound on the take-up roller 160. Multiple guides 1701 are fixedly installed on the base 170, and the cable 1601 is adapted to pass through the arc groove at the bottom of the guide 1701.

[0058] The fixed plate 210 has multiple evenly distributed limiting holes 2101 inside, and the cable 1601 extends through the guide 1701 and the base 170 to the outside of the limiting holes 2101. The cable 1601 extending through the limiting holes 2101 is fixedly connected to the plate end at the bottom of the built-in sliding column 340.

[0059] Preferably, the cable segment of the cable 1601 that extends to the outside of the base 170 is fixed to the plate end at the bottom of the built-in slide column 340 by welding. The auxiliary track 350 has an L-shaped structure, and a rectangular gap is reserved between the auxiliary track 350 and the built-in slide column 340. The outer slide column 310 is located outside the built-in slide column 340, and the auxiliary track 350 is located outside the outer slide column 310. The evenly distributed auxiliary tracks 350, together with the built-in slide column 340, can perform longitudinal and stable lifting and lowering movements along the outer slide column 340.

[0060] When the external slide column 310 and the internal slide column 340 are relatively elongated, in order to enhance the robustness and stability of the elongated structure of the external slide column 310 and the internal slide column 340 under load, the first motor 1201 is operated by the client until the first motor 1201 drives the first shaft 130. The first shaft 130 will drive the two second shafts 140 and the third shaft 150 to rotate at the same speed. Finally, the first shaft 130, the third shaft 150 and the two second shafts 140, which are rectangularly distributed, can drive multiple take-up rollers 160 to rotate at the same speed and in opposite directions, which facilitates the rapid tightening and straightening of the evenly distributed multiple take-up rollers 160. At the same time, the elongated external slide column 310 and the internal slide column 340 can be stabilized and constrained, ensuring that the external slide column 310 and the internal slide column 340 provide stable support for the loaded cargo platform 500 after high-level adjustment, and further provide dynamic balance of the cargo platform 500 after high-level lifting.

[0061] Example 3:

[0062] Combination Figures 5 to 10 As shown, in the above embodiment, studs are provided in the bottom groove and the side groove of the fixing plate 210, and the plate end of the base 170 is fixedly installed on the stud in the bottom groove of the fixing plate 210 by a nut. A positioning plate 230 is inserted into the side groove of the fixing plate 210, and a buckle plate 220 is installed in the gap between the positioning plate 230 and the fixing plate 210. Two rectangular slots are opened on the inner side of the buckle plate 220. The positioning plate 230 is fixedly installed on the stud in the side groove of the fixing plate 210 by a nut.

[0063] Two rectangular plates 3101 are fixedly installed at the bottom of the side slot of the external sliding column 310, and the two rectangular plates 3101 are adapted to be snapped into two rectangular slots on the inner side of the buckle plate 220.

[0064] The top of the side slot of the external slide column 310 is provided with a threaded section, and an anti-detachment baffle 320 is installed on the threaded section. The interior of the internal slide column 340 has four slide tracks 3401. A reinforcing plate 3402 is fixedly installed inside the internal slide column 340, and the plate segment of the anti-detachment baffle 320 is adapted to penetrate into the slide track 3401.

[0065] Preferably, the top side of the fixed plate 210 is reserved with a protruding plate section to provide anti-slip support for the bottom loading platform 500. T-shaped grooves are provided in the protruding plate sections on both sides of the fixed plate 210 to facilitate the stabilization constraint of the retracted auxiliary track 350, further improving the structural strength of the retracted external sliding column 310 and internal sliding column 340. The maximum extension stroke of the high-position column mechanism 300 can be limited by the anti-slip baffle 320.

[0066] In addition, after the four positioning plates 230 clamp and fix the four evenly distributed buckle plates 220, the external sliding column 310 set on the top of the fixed plate 210 and the multiple rectangular plates 3101 at its bottom can be stabilized and clamped by the four buckle plates 220, further improving the structural stability of the external sliding column 310 and the fixed plate 210 after being erected. After the T-shaped protruding sliding plate set on the bottom plate section of the built-in sliding column 340 is adapted to penetrate into the inside of the reinforcing plate 3402, the rotating extended lead screw 260 will lift the ring pad 360, the built-in sliding column 340 and the four auxiliary rails 350 smoothly, providing an effective path for the longitudinal lifting of the cargo platform 500, and avoiding excessive shaking of the cargo platform 500 during the load after being lifted from a high position.

[0067] The working principle and usage process of this invention: According to the usage requirements of the single column stacker, the load-bearing base 110 is pre-arranged on the external rotating motor platform, and the load-bearing base 110 and the rotating motor platform are reinforced and fixed using multiple combination bolts.

[0068] Based on the required lifting height of goods by the single-column stacker crane within the factory, the second motor 1801 operates according to the actual height of the factory's shelving. After the second motor 1801 and the first motor 1201 are started via the client, the rotor inside the second motor 1801, in conjunction with the main auxiliary gear 1802, drives the secondary auxiliary gear 2601. The extended lead screw 260, assembled with two bearings 250, rotates at a constant speed, while the ring washer 360 moves up and down at a constant speed along the threaded section of the extended lead screw 260. At this time, the first motor 1201... The first shaft 130 will drive the two second shafts 140 and the third shaft 150 to rotate at the same speed. Finally, the multiple take-up rollers 160 will maintain the same speed and rotate in opposite directions. The multiple evenly distributed cables 1601 will be released at the same time and loosen in conjunction with the rise of the built-in slide column 340. At the same time, the built-in slide column 340, which is fixed to the outside of the ring pad 360 by multiple locking bolts 3601, will drive the four auxiliary rails 350 to slowly rise and fall until the built-in slide column 340 and the external slide column 310 extend relative to each other and adapt to the height of the rack in the factory.

[0069] When the outer slide column 310 and the inner slide column 340 are extended relative to each other until the height is selected, the first motor 1201 is reversed. The reversed first shaft 130 will drive the two second shafts 140 and the third shaft 150 to rotate in the opposite direction. Finally, the multiple take-up rollers 160 will take up the multiple cables 1601 in the opposite direction at the same speed until the inner slide column 340 is tightened and constrained by the multiple cables 1601. At this time, the outer slide column 310 and the inner slide column 340, which are in a relatively extended state, are stabilized by the inner frame 240 as the support carrier.

[0070] In use, the external lifting motor is fixedly installed on a selected first assembly platform 410 or second assembly platform 420, and bolts are used to secure the lifting motor to the selected first assembly platform 410 and second assembly platform 420. The running lifting motor, in conjunction with the lifting chain, pulls the loading platform 500 up and down at a constant speed along the four main tracks 330 and four auxiliary tracks 350. After the external sliding column 310 and the internal sliding column 340 extend relative to each other, together with the four auxiliary tracks 350 that rise synchronously with the internal sliding column 340, they can provide sufficiently effective support for the longitudinal lifting of the loading platform 500, together with the stationary four main tracks 330.

[0071] Both the external sliding column 310 and the internal sliding column 340 are designed as hollow structures, with the climbing assist mechanism 200 as the carrier. Depending on the changes in the height of the factory and the different dimensions of the racks, the lightweight adaptive height-adjustable column can provide an effective climbing path for the loading platform 500 and its externally mounted stacking arms and balancing modules, facilitating the safety and stability of the new column after height adjustment.

[0072] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
