AI Technical Summary
[0002]随着物流行业的不断发展，对自动化立体仓库存储货架上的存储货位的需求也在增长；在自动化立体仓库占地有限的情况下，储物空间只能向空中发展，导致立体仓库货架越建越高；在立体仓库货架高度增高的同时，作为核心搬运设备的堆垛机高度也随之不断增高，出现了超高堆垛机；超高堆垛机整体增高后，作为提升动力载体的提升钢丝绳需要贯穿整个设备的高度，从堆垛机的顶部定滑轮到底部提升卷筒之间的钢丝绳长度较长，并处于无限位状态下；出于对超高堆垛机维护要求，在堆垛机立柱一侧会分别设置维修爬梯、安全护笼和检修平台等设施，这些设施与提升钢丝绳并列设置；超高堆垛机又属于高速运行设备，在其加速和减速运行时，处于无限位状态下的提升钢丝绳就会沿堆垛机运行方向出现前后的剧烈晃动，此时前后晃动的提升钢丝绳就会与维修爬梯支架和检修平台上预留的穿绳孔洞出现较大冲击力的磕撞现象，使钢丝绳出现损伤，给堆垛机平台的升降运行带来了安全隐患；另外，由于提升钢丝绳在升降过程中需要在卷筒上左右移动进行缠绕，导致无法对提升钢丝绳设置强制固定机构；如何开发一种可以安装在超高堆垛机爬梯底部，既能解决钢丝绳在高速运行时有效抑制其前后晃动，又能在钢丝绳缠绕到卷筒上时可以跟随钢丝绳自由进行左右移动的机构，成为现有超高堆垛机急需要解决的一个难题

Abstract
Description
Technical Field
[0001] This invention relates to an ultra-high stacker crane, and more particularly to a follow-up mechanism and working method for the lifting wire rope of an ultra-high stacker crane that also has a wire rope anti-sway function. Background Technology
[0002] With the continuous development of the logistics industry, the demand for storage locations on automated storage and retrieval systems (AS / RS) racks is also increasing. Given the limited space available in AS / RS, storage space can only be expanded vertically, leading to increasingly taller racks. As the rack height increases, the height of the stacker cranes, the core handling equipment, also rises, resulting in ultra-high stacker cranes. With the increased height of ultra-high stacker cranes, the lifting wire ropes, which serve as the lifting power carrier, need to run through the entire height of the equipment. The length of the wire rope from the top fixed pulley to the bottom lifting drum is relatively long and is in an unlimited state. Due to maintenance requirements, maintenance ladders, safety cages, and inspection platforms are installed on one side of the stacker crane's columns, alongside the lifting wire ropes. Furthermore, ultra-high stacker cranes are high-speed... When the equipment is running, the lifting wire rope, which is in an unlimited position, will violently sway back and forth along the direction of the stacker crane's operation during acceleration and deceleration. At this time, the swaying lifting wire rope will collide with the rope threading holes reserved on the maintenance ladder support and inspection platform with a large impact force, causing damage to the wire rope and posing a safety hazard to the lifting and lowering operation of the stacker crane platform. In addition, since the lifting wire rope needs to move left and right on the drum to wind around during the lifting and lowering process, it is impossible to set up a forced fixing mechanism for the lifting wire rope. How to develop a mechanism that can be installed at the bottom of the ladder of the ultra-high stacker crane, which can effectively suppress the back and forth swaying of the wire rope during high-speed operation, and can move freely left and right with the wire rope when it is wound on the drum, has become an urgent problem to be solved for existing ultra-high stacker cranes. Summary of the Invention
[0003] This invention provides a follow-up mechanism for the lifting wire rope of an ultra-high stacker crane that can prevent swaying. It can effectively suppress the back-and-forth swaying of the wire rope when the stacker crane is running at high speed, and can also follow the wire rope that is freely wound on the drum.
[0004] The present invention solves the above technical problems through the following technical solutions: A follow-up mechanism for the lifting wire rope of an ultra-high stacker crane with anti-sway capability includes a stacker crane portal frame, a lifting platform nested within the portal frame, a fixed pulley block at the top of the portal frame, a maintenance ladder assembly on the outer surface of the left column of the portal frame, and a lifting drive device on the outer surface of the left column below the maintenance ladder assembly. The lifting drive device has a front wire rope drum and a rear wire rope drum. The front lifting wire rope on the front drum passes vertically upward through the fixed pulley block and connects to the left end of the lifting platform. The rear lifting wire rope on the rear drum passes through the fixed pulley block and connects to the right end of the lifting platform. The maintenance ladder assembly is positioned between the front and rear lifting wire ropes above the lifting drive device. A slide rail fixing seat is provided on the outer surface of the left column above the lifting drive device. A horizontal slide rail is provided on the fixed base along the front-to-back direction. A front slider and a rear slider are respectively mounted on the horizontal slide rail. A front fixed pivot is mounted on the front slider. The middle parts of the two front limit wheel swing plates are movably sleeved on the front fixed pivot. A counterclockwise torsion spring is sleeved on the front fixed pivot between the two front limit wheel swing plates and the front slider. One end of the counterclockwise torsion spring is fixedly connected to the front slider, and the other end of the counterclockwise torsion spring is fixedly connected to the two front limit wheels. The two front limit wheel swing plates are fixedly connected together. A front upper limit V-groove pulley axle is provided at one end of the two front limit wheel swing plates. A front upper limit V-groove pulley is provided on the front upper limit V-groove pulley axle. A front lower limit V-groove pulley axle is provided at the other end of the two front limit wheel swing plates. A front lower limit V-groove pulley is provided on the front lower limit V-groove pulley axle. The front lifting wire rope is movably arranged between the front upper limit V-groove pulley and the front lower limit V-groove pulley.
[0005] A rear fixed rotating shaft is provided on the rear slider. The middle part of the two rear limit wheel swing plates is movably sleeved on the rear fixed rotating shaft. A clockwise torsion spring is sleeved on the rear fixed rotating shaft between the two rear limit wheel swing plates and the rear slider. One end of the clockwise torsion spring is fixedly connected to the rear slider, and the other end of the clockwise torsion spring is fixedly connected to the two rear limit wheel swing plates. A rear upper limit V-groove pulley axle is provided at one end of the two rear limit wheel swing plates. A rear upper limit V-groove pulley is provided on the rear upper limit V-groove pulley axle. A rear lower limit V-groove pulley axle is provided at the other end of the two rear limit wheel swing plates. A rear lower limit V-groove pulley is provided on the rear lower limit V-groove pulley axle. The rear lifting wire rope is set between the rear upper limit V-groove pulley and the rear lower limit V-groove pulley.
[0006] A method for operating a follow-up mechanism for an anti-sway ultra-high stacker crane lifting wire rope is characterized by: a counterclockwise torsion spring constantly providing torque to the two front limit wheel swing plates for clockwise rotation, causing the right side of the front upper limit V-groove pulley to engage with the left side of the front lifting wire rope, and the left side of the front lower limit V-groove pulley to engage with the right side of the front lifting wire rope, thus engaging a section of the front lifting wire rope between the front upper limit V-groove pulley and the front lower limit V-groove pulley, thereby achieving constant dynamic tension of the front lifting wire rope. The clockwise torsion spring constantly provides the two rear limit wheel swing plates with counterclockwise torque, so that the left side of the rear upper limit V-groove pulley is in contact with the right side of the rear lifting wire rope, and the right side of the rear lower limit V-groove pulley is in contact with the left side of the rear lifting wire rope. A section of the rear lifting wire rope is also engaged in an arc shape between the upper limit V-groove pulley and the rear lower limit V-groove pulley, thus achieving the effect of always dynamically tensioning the rear lifting wire rope. This avoids large swinging of the two lifting wire ropes when the ultra-high stacker crane starts or stops.
[0007] When the lifting platform of the ultra-high stacker crane is raised and lowered, the front slider slides along the horizontal slide rail in the direction of movement of the front lifting wire rope wound on the front drum of the wire rope; at the same time, the rear slider slides along the horizontal slide rail in the direction of movement of the rear lifting wire rope wound on the rear drum of the wire rope; thus realizing that the two sliders on the horizontal slide rail follow the movement of the wire rope. The horizontal slide rail, the front slider, the rear slider, the two front limit wheel swing plates, the two rear limit wheel swing plates, the front upper limit V-groove pulley, the front lower limit V-groove pulley, the rear upper limit V-groove pulley, and the rear lower limit V-groove pulley form an integrated anti-sway limiting follow-up mechanism. On the outer surface of the left column above the lifting drive device, multiple sets of anti-sway limiting follow-up mechanisms can be installed at intervals to further tension the lifting wire rope.
[0008] This invention utilizes the reaction force of a torsion spring to keep the limit wheel swing plate in a state of constant outward rotation and swing. This causes the upper and lower limit V-groove pulleys mounted on the limit wheel swing plate to engage with the lifting wire rope, tightening the wire rope and thus overcoming the large swing of the wire rope when the stacker crane starts or stops. When the lifting wire rope moves back and forth on the drum, the entire limiting device follows the movement of the slider and the slide rail. The upper and lower sets of limit V-groove pulleys solve the problem of wire rope swaying in the running direction during the operation of the entire equipment. At the same time, the slide rail slider achieves follow-up movement, improving the overall stability and safety of the wire rope during movement. Attached Figure Description

[0010] The present invention will now be described in detail with reference to the accompanying drawings: A follow-up mechanism for the lifting wire rope of an ultra-high stacker crane with anti-sway capability includes a stacker crane portal frame 1, a lifting platform 2 nested within the portal frame 1, a fixed pulley assembly 24 at the top of the portal frame 1, a maintenance ladder assembly 4 on the outer surface of the left column of the portal frame 1, and a lifting drive device 3 on the outer surface of the left column below the maintenance ladder assembly 4. A front wire rope drum 7 and a rear wire rope drum 8 are respectively mounted on the lifting drive device 3. The front lifting wire rope 5 on the front drum 7 passes vertically upward through the fixed pulley assembly 24 and is connected to the left end of the lifting platform 2. The rear wire rope... The rear lifting wire rope 6 on the drum 8 is connected to the right end of the lifting platform 2 via the fixed pulley group 24. The maintenance ladder assembly 4 is located between the front lifting wire rope 5 and the rear lifting wire rope 6 above the lifting drive device 3. The lifting drive device 3 achieves the lifting and lowering of the lifting platform 2 by winding the two lifting wire ropes on the corresponding wire rope drums. On the outer surface of the left column above the lifting drive device 3, a slide rail fixing seat 10 is provided. On the slide rail fixing seat 10, a horizontal slide rail 11 is provided along the front-rear direction. A front slider 12 and a rear slider 18 are respectively provided on the horizontal slide rail 11. A front fixed rotating shaft 13 is provided on the front slider 12. The middle part of the front limit wheel swing plate 15 is movably sleeved on the front fixed rotating shaft 13. A counterclockwise torsion spring 14 is sleeved on the front fixed rotating shaft 13 between the two front limit wheel swing plates 15 and the front slider 12. One end of the counterclockwise torsion spring 14 is fixedly connected to the front slider 12, and the other end is fixedly connected to the two front limit wheel swing plates 15. A front upper limit V-groove pulley shaft 26 is provided at one end of the two front limit wheel swing plates 15, and a front upper limit V-groove pulley 16 is provided on the front upper limit V-groove pulley shaft 26. A front lower limit V-groove pulley shaft 25 is provided at the other end of the two front limit wheel swing plates 15. A front lower limit V-groove pulley 17 is provided on the pulley axle 25 of the grooved pulley; the front lifting wire rope 5 is movably arranged between the front upper limit V-groove pulley 16 and the front lower limit V-groove pulley 17; the counterclockwise torsion spring 14 drives the two front limit wheel swing plates 15 to swing clockwise, but because the front lifting wire rope 5 is provided between the front upper limit V-groove pulley 16 and the front lower limit V-groove pulley 17, the front lifting wire rope 5 provides a reverse resistance torque for the clockwise swing of the two front limit wheel swing plates 15 through the two V-groove pulleys. After the two forces are balanced, a section of the front lifting wire rope 5 is dynamically engaged between the two pulleys in an arc shape, which plays the role of tensioning the entire vertically arranged front lifting wire rope 5.
[0011] A rear fixed pivot 19 is provided on the rear slider 18. The middle part of the two rear limit wheel swing plates 21 is movably sleeved on the rear fixed pivot 19. A clockwise torsion spring 20 is sleeved on the rear fixed pivot 19 between the two rear limit wheel swing plates 21 and the rear slider 18. One end of the clockwise torsion spring 20 is fixedly connected to the rear slider 18, and the other end of the clockwise torsion spring 20 is fixedly connected to the two rear limit wheel swing plates 21. A rear upper limit V-groove pulley axle 27 is provided at one end of the two rear limit wheel swing plates 21. A rear upper limit V-groove pulley 22 is provided on the rear upper limit V-groove pulley axle 27. A rear lower limit V-groove pulley is provided at the other end of the two rear limit wheel swing plates 19. A rear lower limit V-groove pulley 23 is provided on the rear lower limit V-groove pulley axle 9; the rear lifting wire rope 6 is located between the rear upper limit V-groove pulley 22 and the rear lower limit V-groove pulley 23; the clockwise torsion spring 20 drives the two rear limit wheel swing plates 21 to swing counterclockwise, but because the rear lifting wire rope 6 is provided between the rear upper limit V-groove pulley axle 27 and the rear lower limit V-groove pulley axle 9, the rear lifting wire rope 6 provides a reverse resistance torque for the counterclockwise swing of the two rear limit wheel swing plates 21 through the two V-groove pulleys. After the two forces are balanced, a section of the rear lifting wire rope 6 is dynamically engaged in an arc shape between the two pulleys, which plays the role of tensioning the entire vertically arranged front lifting wire rope 6.
[0012] The counterclockwise torsion spring 14 constantly provides the two front limit wheel swing plates 15 with clockwise rotation torque, causing the right side of the front upper limit V-groove pulley 16 to be in contact with the left side of the front lifting wire rope 5, and the left side of the front lower limit V-groove pulley 17 to be in contact with the right side of the front lifting wire rope 5, thus engaging a section of the front lifting wire rope 5 between the front upper limit V-groove pulley 16 and the front lower limit V-groove pulley 17, thereby achieving the function of constantly dynamically tensioning the front lifting wire rope 5; the clockwise torsion spring 20 constantly provides the two rear limit wheels with torque. The counterclockwise rotation torque of the position wheel swing plate 21 causes the left side of the upper rear V-groove pulley 22 to engage with the right side of the rear lifting wire rope 6, and the right side of the lower rear V-groove pulley 23 to engage with the left side of the rear lifting wire rope 6. This also causes a section of the rear lifting wire rope 6 to be arc-shapedly engaged between the upper rear V-groove pulley 22 and the lower rear V-groove pulley 23, thus ensuring that the rear lifting wire rope 6 is always dynamically tensioned. This prevents the two lifting wire ropes from swinging significantly when the ultra-high stacker crane starts or stops.
[0013] When the lifting platform 2 of the ultra-high stacker crane is raised or lowered, the front slider 12 slides along the horizontal slide rail 11 in the direction of movement of the front lifting wire rope 5 as it is wound on the front drum 7; at the same time, the rear slider 18 slides along the horizontal slide rail 11 in the direction of movement of the rear lifting wire rope 6 as it is wound on the rear drum 8; thus, the two sliders on the horizontal slide rail 11 move with the wire rope.
