Description

堆垛机维修装置Stacker maintenance equipment

技术领域Technical Field

本实用新型涉及维修设备技术领域,尤其涉及一种堆垛机维修装置。The utility model relates to the technical field of maintenance equipment, in particular to a stacker maintenance device.

背景技术Background technique

随着用于存储产品的货架设计越来越高,高架堆垛机得到广泛应用。高架堆垛机能够将产品放到高层货架或从高层货架上取下来。而为了保证生产的顺利进行,高架堆垛机的维护是重中之重。As the shelves used to store products are designed to be higher and higher, high-bay stackers are widely used. High-bay stackers can put products on or take them off high-bay shelves. In order to ensure the smooth progress of production, the maintenance of high-bay stackers is a top priority.

目前,用于维修高架堆垛机的装置主要有以下两种:一种是依托于高架堆垛机机架设置的爬梯加站台,人员携带体积较大的维护用品沿爬梯攀爬时较为困难,安全性难以保障;另一种是采用单桅柱铝合金升降平台,该升降平台虽然能够实现自动升降,但仅对维修平台的一侧进行支撑,在负载过重时会产生晃动,安全性也难以得到保障。At present, there are mainly two types of devices used to repair overhead stackers: one is a ladder and platform installed on the frame of the overhead stacker. It is difficult for personnel to climb up the ladder with large maintenance supplies, and safety is difficult to ensure; the other is a single-mast aluminum alloy lifting platform. Although the lifting platform can be automatically raised and lowered, it only supports one side of the maintenance platform. When the load is too heavy, it will shake, and safety is difficult to ensure.

首先对高架堆垛机的结构进行简单说明。参考图1所示,高架堆垛机包括机架30、升降载货台40、X轴驱动组件50、Y轴驱动组件60、Z轴驱动组件70,X轴、Y轴、Z轴两两垂直,Y轴为竖直方向,其中机架30整体呈矩形框架结构,包括两根竖直设置的立柱303以及分别连接立柱303两端的上横梁301和下横梁302,上横梁301和下横梁302上均设置有滑轮304,在X轴驱动组件50作用下,机架30能够沿沿X轴设置的天轨10和地轨20滑动,同时升降载货台40还能在Y轴驱动组件60沿Y轴移动,升降载货台40上的货叉能够在Z轴驱动组件作用下相对于机架30沿Z轴移动。而机架30的整体一般设置在5m左右,仅在地面作业难以实现对高架堆垛机特别是天轨10部分的检修维护。First, the structure of the overhead stacker is briefly described. As shown in FIG1 , the overhead stacker includes a frame 30, a lifting platform 40, an X-axis drive assembly 50, a Y-axis drive assembly 60, and a Z-axis drive assembly 70. The X-axis, Y-axis, and Z-axis are perpendicular to each other, and the Y-axis is in the vertical direction. The frame 30 is a rectangular frame structure as a whole, including two vertically arranged columns 303 and an upper beam 301 and a lower beam 302 respectively connected to the two ends of the columns 303. The upper beam 301 and the lower beam 302 are both provided with pulleys 304. Under the action of the X-axis drive assembly 50, the frame 30 can slide along the ceiling rail 10 and the ground rail 20 arranged along the X-axis. At the same time, the lifting platform 40 can also move along the Y-axis in the Y-axis drive assembly 60. The fork on the lifting platform 40 can move along the Z-axis relative to the frame 30 under the action of the Z-axis drive assembly. The entire frame 30 is generally arranged at about 5 m, and it is difficult to perform inspection and maintenance of the overhead stacker, especially the overhead rail 10 , only by working on the ground.

基于此,在考虑到安全性的前提下,本实用新型提出一种堆垛机维修装置,主要用于修理高架堆垛机。图2-图3所示的是本实用新型的实施例中提出的一种堆垛机维修装置,该维修装置设置于高架堆垛机的机架30一侧,包括基座1、维修平台4、第一伸缩杆2和第二伸缩杆3以及升降驱动件5,基座1作为安装和支撑基础,第一伸缩杆2和第二伸缩杆3均沿Y轴方向安装于基座1上,维修平台4位于基座1上方,且第一伸缩杆2和第二伸缩杆3沿X轴方向间隔设置于基座1的相对两侧并与基座1固接,在升降驱动件5驱动下,第一伸缩杆2和第二伸缩杆3能够同步伸缩以带动维修平台4升降,维修平台4包括底板41以及围设于底板41四周的护栏42,维修人员可以在护栏42围合形成的操作空间内对堆垛机进行维修。为了给维修人员提供一定的活动空间,底板41设置为长宽为650mm*650mm的正方形,护栏42的高度为1000mm。Based on this, and taking safety into consideration, the utility model proposes a stacker maintenance device, which is mainly used to repair an elevated stacker. Figures 2 and 3 show a stacker maintenance device proposed in an embodiment of the utility model. The maintenance device is arranged on one side of the frame 30 of the elevated stacker, and includes a base 1, a maintenance platform 4, a first telescopic rod 2, a second telescopic rod 3, and a lifting drive 5. The base 1 serves as an installation and support base. The first telescopic rod 2 and the second telescopic rod 3 are both installed on the base 1 along the Y-axis direction. The maintenance platform 4 is located above the base 1, and the first telescopic rod 2 and the second telescopic rod 3 are arranged at intervals on opposite sides of the base 1 along the X-axis direction and are fixed to the base 1. Under the drive of the lifting drive 5, the first telescopic rod 2 and the second telescopic rod 3 can be synchronously extended to drive the maintenance platform 4 to rise and fall. The maintenance platform 4 includes a bottom plate 41 and a guardrail 42 arranged around the bottom plate 41. Maintenance personnel can repair the stacker in the operating space formed by the guardrail 42. In order to provide maintenance personnel with a certain amount of space for activities, the bottom plate 41 is configured as a square with a length and width of 650 mm*650 mm, and the height of the guardrail 42 is 1000 mm.

第一伸缩杆2和第二伸缩杆3分别连接在维修平台4的两侧,第一伸缩杆2和第二伸缩杆3能够在升降驱动件5驱动下做同步伸缩,进而使维修平台4的相对两侧都得到支撑,提高了维修平台4的稳定性和安全性能。The first telescopic rod 2 and the second telescopic rod 3 are respectively connected to the two sides of the maintenance platform 4. The first telescopic rod 2 and the second telescopic rod 3 can be synchronously extended and retracted under the drive of the lifting drive member 5, so that the opposite sides of the maintenance platform 4 are supported, thereby improving the stability and safety performance of the maintenance platform 4.

本实施例中,第二伸缩杆3的数量为两根,两根第二伸缩杆3沿Z轴方向间隔设置于维修平台4的底部,两根第二伸缩杆3与第一伸缩杆2形成三角结构,能更稳定的支撑维修平台。为了降低维修成本,第一伸缩杆2为主动伸缩杆,升降驱动件5与第一伸缩杆2连接,在升降驱动件5作用下,第一伸缩杆伸缩,第二伸缩杆3为从动伸缩杆,第一伸缩杆2伸缩时,带动维修平台4升降,而维修平台4又带动第二伸缩杆3被动伸缩。在其他实施例中,第二伸缩杆3的数量可以是2以上任意数量。In this embodiment, the number of the second telescopic rods 3 is two, and the two second telescopic rods 3 are arranged at intervals along the Z-axis direction at the bottom of the maintenance platform 4. The two second telescopic rods 3 and the first telescopic rod 2 form a triangular structure, which can more stably support the maintenance platform. In order to reduce the maintenance cost, the first telescopic rod 2 is an active telescopic rod, and the lifting drive 5 is connected to the first telescopic rod 2. Under the action of the lifting drive 5, the first telescopic rod is extended and retracted, and the second telescopic rod 3 is a driven telescopic rod. When the first telescopic rod 2 is extended and retracted, it drives the maintenance platform 4 to rise and fall, and the maintenance platform 4 drives the second telescopic rod 3 to passively extend and retract. In other embodiments, the number of the second telescopic rods 3 can be any number greater than 2.

可选地,第一伸缩杆2包括固定桅柱21和一级升降桅柱22,固定桅柱21竖直安装在基座1上,一级升降桅柱22设置有第一滑块,第一滑块嵌于固定桅柱21设置的第一轨道槽内,一级升降桅柱22与固定桅柱21通过第一滑块与第一轨道槽沿竖直方向滑动连接,升降驱动件5的输出端与一级升降桅柱22靠近基座1的一端连接,从而推动一级升降桅柱22升降。Optionally, the first telescopic rod 2 includes a fixed mast 21 and a first-level lifting mast 22, the fixed mast 21 is vertically installed on the base 1, the first-level lifting mast 22 is provided with a first slider, the first slider is embedded in a first track groove provided on the fixed mast 21, the first-level lifting mast 22 is slidably connected with the fixed mast 21 along the vertical direction through the first slider and the first track groove, and the output end of the lifting drive 5 is connected to one end of the first-level lifting mast 22 close to the base 1, thereby pushing the first-level lifting mast 22 to rise and fall.

第二伸缩杆3包括固定套筒31、活动杆32和定位件33,固定套筒31竖直安装在基座1上,活动杆32一端插入固定套筒31内与固定套筒31滑动套接,另一端与维修平台4的底板41的底面固接,定位件33处于锁定状态时能够对活动杆32进行轴向限位。The second telescopic rod 3 includes a fixed sleeve 31, a movable rod 32 and a positioning member 33. The fixed sleeve 31 is vertically installed on the base 1. One end of the movable rod 32 is inserted into the fixed sleeve 31 and slidably connected with the fixed sleeve 31, and the other end is fixedly connected to the bottom surface of the bottom plate 41 of the maintenance platform 4. When the positioning member 33 is in a locked state, the movable rod 32 can be axially limited.

本实施例中,升降驱动件5采用电动缸,电动缸一端固定在基座1上,另一端与一级升降桅柱22靠近基座1的一端固接。现有电动缸的行程有限,难以使维修平台升高到高架堆垛机的天轨10所在的高度。基于此,第一伸缩杆2还包括二级升降桅柱23,固定桅柱21、一级升降桅柱22、二级升降桅柱23的长度均为2m,二级升降桅柱23设置有第二滑块,一级升降桅柱22背向固定桅柱21的一侧设置有第二轨道槽,第二滑块嵌于第二轨道槽内,二级升降桅柱23与一级升降桅柱22通过第二滑块与第二轨道槽滑动连接,维修平台4与二级升降桅柱23固接,一级升降桅柱22远离基座1的一端转动安装有第一转向轮24,二级升降桅柱23靠近基座1的一端安装有第二转向轮25,第一转向轮24和第二转向轮25通过传动链条26传动连接,传动链条26的第一端与固定桅柱21固接,第二端依次绕过第一转向轮24、第二转向轮25与二级升降桅柱23固接。In this embodiment, the lifting drive member 5 is an electric cylinder, one end of which is fixed on the base 1, and the other end is fixed to one end of the first-stage lifting mast 22 close to the base 1. The stroke of the existing electric cylinder is limited, and it is difficult to raise the maintenance platform to the height of the overhead rail 10 of the overhead stacker. Based on this, the first telescopic rod 2 also includes a secondary lifting mast 23. The lengths of the fixed mast 21, the first lifting mast 22 and the second lifting mast 23 are all 2m. The second lifting mast 23 is provided with a second slider. The first lifting mast 22 is provided with a second track groove on the side facing away from the fixed mast 21. The second slider is embedded in the second track groove. The secondary lifting mast 23 and the first lifting mast 22 are slidably connected with the second track groove through the second slider. The maintenance platform 4 is fixedly connected to the secondary lifting mast 23. The first end of the first lifting mast 22 away from the base 1 is rotatably installed with a first steering wheel 24. The second end of the secondary lifting mast 23 close to the base 1 is installed with a second steering wheel 25. The first steering wheel 24 and the second steering wheel 25 are connected by a transmission chain 26. The first end of the transmission chain 26 is fixedly connected to the fixed mast 21, and the second end is fixedly connected to the secondary lifting mast 23 by bypassing the first steering wheel 24 and the second steering wheel 25 in sequence.

当电动缸驱动一级升降桅柱22升降时,第一转向轮24与传动链条26的第一端的距离发生变化,由于传动链条26的总长度不变,第二转向轮25与传动链条26的第二端的距离也不变,所以第一转向轮24与第二转向轮25之间的距离必然发生变化,二级升降桅柱23相对于一级升降桅柱22也产生与一级升降桅柱22同步的升降运动,结合一级升降桅柱22的运动,二级升降桅柱23以及与二级升降桅柱23固接的维修平台4升降行程是一级升降桅柱22行程的两倍。When the electric cylinder drives the first-stage lifting mast 22 to rise and fall, the distance between the first steering wheel 24 and the first end of the transmission chain 26 changes. Since the total length of the transmission chain 26 remains unchanged, the distance between the second steering wheel 25 and the second end of the transmission chain 26 also remains unchanged. Therefore, the distance between the first steering wheel 24 and the second steering wheel 25 will inevitably change. The second-stage lifting mast 23 also generates a lifting movement synchronous with the first-stage lifting mast 22 relative to the first-stage lifting mast 22. Combined with the movement of the first-stage lifting mast 22, the lifting stroke of the second-stage lifting mast 23 and the maintenance platform 4 fixed to the second-stage lifting mast 23 is twice that of the first-stage lifting mast 22.

以一级升降桅柱22上升为例,假设传动链条26的总长度为L,传动链条26自第一端到连接第一转向轮24的部分初始长度为s1,传动链条26自第二端到连接第二转向轮25的部分长度为s2,则传动链条26自第一转向轮24到第二转向轮25的部分长度l=L-s1-s2,一级升降桅柱22带动第一转向轮24向上运动h,则l=L-(s1+h)-s2,也就是说第一转向轮24和第二转向轮25之间的距离减小了h,因此二级升降桅柱23相对于一级升降桅柱22上升且上升高度与一级升降桅柱22上升高度一致。在其他实施例中,一级升降桅柱22的数量可以是任意数量,二级升降桅柱23的数量可以是任意数量,或者再设置三级升降桅柱、四级升降桅柱等等,前一级升降桅柱与后一级升降桅柱之间通过与第一转向轮24、二转向轮25和传动链条26相同的传动机构或不同的传动机构实现传动连接。在其他实施例中,第一伸缩杆2还可以采用伸缩云梯,伸缩云梯属于现有技术,在这里不再做进一步的说明。Taking the rising of the first-stage lifting mast 22 as an example, assuming that the total length of the transmission chain 26 is L, the initial length of the portion of the transmission chain 26 from the first end to the portion connected to the first steering wheel 24 is s 1 , and the length of the portion of the transmission chain 26 from the second end to the portion connected to the second steering wheel 25 is s 2 , then the length of the portion of the transmission chain 26 from the first steering wheel 24 to the second steering wheel 25 is l=Ls 1 -s 2 , and the first-stage lifting mast 22 drives the first steering wheel 24 to move upward by h, then l=L-(s 1 +h)-s 2 , that is, the distance between the first steering wheel 24 and the second steering wheel 25 is reduced by h, so the second-stage lifting mast 23 rises relative to the first-stage lifting mast 22 and the rising height is consistent with the rising height of the first-stage lifting mast 22. In other embodiments, the number of the first-stage lifting masts 22 can be any number, the number of the second-stage lifting masts 23 can be any number, or a third-stage lifting mast, a fourth-stage lifting mast, etc. can be provided, and the first-stage lifting mast and the second-stage lifting mast are connected to each other by a transmission mechanism that is the same as the first steering wheel 24, the second steering wheel 25 and the transmission chain 26 or a different transmission mechanism. In other embodiments, the first telescopic rod 2 can also adopt a telescopic ladder, which belongs to the prior art and will not be further described here.

基于堆垛机5m高的设定,电动缸选用行程为2m、负载能力为1000kg的电动缸,该电动缸足以承载维修平台4自身的重量以及维修人员和常用检修工具的重量。需要考虑到的是,为了方便维修人员进入维修平台4,维修平台4的初始高度不能过高,基于一般人员的身高,维修平台4的初始高度设置为500mm,则电动缸需选用多级电动缸以满足维修平台4上升的行程需求。同时,第二伸缩杆3处于收缩状态时其长度不能大于500mm,也就是说固定套筒31和活动杆32的长度都不能长于500mm。因此,活动杆32由依次套接的若干级支杆构成,分别为一级支杆、二级支杆……,除连接于维修平台4的最后一级支杆外,前级支杆均设置为空心,后级支杆依次插入前一级支杆内并与前一级支杆滑动套接,也就是说,若干级支杆之间轴向可伸缩。在其他实施例中,支杆的级数可以是2以上任意数量。Based on the setting of 5m height of the stacker, the electric cylinder uses an electric cylinder with a stroke of 2m and a load capacity of 1000kg, which is sufficient to bear the weight of the maintenance platform 4 itself as well as the weight of the maintenance personnel and common maintenance tools. It should be taken into account that in order to facilitate the maintenance personnel to enter the maintenance platform 4, the initial height of the maintenance platform 4 cannot be too high. Based on the height of ordinary people, the initial height of the maintenance platform 4 is set to 500mm, so the electric cylinder needs to use a multi-stage electric cylinder to meet the stroke requirement of the maintenance platform 4. At the same time, the length of the second telescopic rod 3 when it is in a retracted state cannot be greater than 500mm, that is, the length of the fixed sleeve 31 and the movable rod 32 cannot be longer than 500mm. Therefore, the movable rod 32 is composed of several levels of support rods that are sleeved in sequence, namely, the first-level support rod, the second-level support rod..., except for the last-level support rod connected to the maintenance platform 4, the front-level support rods are all set to be hollow, and the rear-level support rods are inserted into the previous-level support rods in sequence and slidably sleeved with the previous-level support rods, that is, the axial extension between the several-level support rods is retractable. In other embodiments, the number of levels of support rods can be any number above 2.

考虑到操作便利性,同时为了保障维修人员的人身安全,维修平台上设置有操控台,操控台至少包括用于控制电动缸伸缩的控制按钮以及急停按钮,控制电压为DC24V,能够有效保证操作人员的安全。除此之外,电动缸还具备停电自锁功能,能够避免停电时维修平台迅速下坠。Considering the convenience of operation and to ensure the personal safety of maintenance personnel, a control panel is set on the maintenance platform. The control panel includes at least control buttons for controlling the extension and retraction of the electric cylinder and an emergency stop button. The control voltage is DC24V, which can effectively ensure the safety of operators. In addition, the electric cylinder also has a power-off self-locking function, which can prevent the maintenance platform from falling rapidly during a power outage.

四面围合的护栏42包括护栏主体和防护门,防护门与护栏主体活动连接以方便维修人员进入维修空间。示例性地,防护门与护栏主体铰接,同时为了提高维修人员高空作业时的安全性,防护门上设置有插销,护栏主体上设置有供插销插入的插孔,当插销插入插孔后,防护门与护栏主体之间相对静止。The guardrail 42 surrounded on all sides includes a guardrail body and a protective door, and the protective door is movably connected to the guardrail body to facilitate maintenance personnel to enter the maintenance space. For example, the protective door is hinged to the guardrail body, and in order to improve the safety of maintenance personnel during high-altitude operations, a latch is provided on the guardrail body, and a socket for the latch to be inserted is provided on the guardrail body. When the latch is inserted into the socket, the guardrail body is relatively stationary.

第一伸缩杆2和第二伸缩杆3均按照承重1000kg进行选型,第一伸缩杆2中的各级桅柱(包括固定桅柱21)可以选用尺寸200*95的宽幅型材,而第二伸缩杆3位于最后一级的活动杆32选用直径40mm的柱形型材,前一级活动杆32的直径大于后一级活动杆32的直径。更进一步地,第一伸缩杆2和第二伸缩杆3均采用铝合金制成,质轻且强度高。The first telescopic rod 2 and the second telescopic rod 3 are both selected according to the load-bearing capacity of 1000kg. The masts of each level (including the fixed mast 21) in the first telescopic rod 2 can be selected from wide profiles of 200*95, and the movable rod 32 at the last level of the second telescopic rod 3 is selected from a columnar profile with a diameter of 40mm, and the diameter of the previous movable rod 32 is larger than the diameter of the next movable rod 32. Furthermore, the first telescopic rod 2 and the second telescopic rod 3 are both made of aluminum alloy, which is light and high in strength.

本实施例中,定位件33包括弹簧钢珠,弹簧钢珠安装在活动杆32的每一级支杆的外壁上,并与固定套筒31或前一级支杆内壁上设置的槽孔配合使用,即相邻两级支杆之间均设置有上述弹簧钢珠,当弹簧钢珠移动至与槽孔对应时,在弹性势能作用下,弹簧钢珠卡位于槽孔内实现卡位,完成对维修平台4的支撑。示例性地,弹簧钢珠的直径为10mm。显然,本实用新型的上述实施例仅仅是为了清楚说明本实用新型所作的举例,而并非是对本实用新型的实施方式的限定。对于所属领域的普通技术人员来说,能够进行各种明显的变化、重新调整和替代而不会脱离本实用新型的保护范围。这里无需也无法对所有的实施方式予以穷举。凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本实用新型权利要求的保护范围之内。In this embodiment, the positioning member 33 includes a spring steel ball, which is installed on the outer wall of each level of the active rod 32 and is used in conjunction with the slot hole set on the inner wall of the fixed sleeve 31 or the previous level of the support rod, that is, the above-mentioned spring steel ball is set between the two adjacent levels of the support rod. When the spring steel ball moves to correspond to the slot hole, under the action of elastic potential energy, the spring steel ball is locked in the slot hole to achieve the locking position, and the maintenance platform 4 is supported. Exemplarily, the diameter of the spring steel ball is 10mm.
