Description
技术领域：Technical field:
本发明涉及一种捞渣起重设备，主要是一种铝电解捞渣抓斗的设计方法。The invention relates to a lifting device for slag removal, mainly a design method of an aluminum electrolysis slag grab.
背景技术：Background technique:
目前，铝电解起重设备中的捞渣抓斗普遍存在一种情况：抓斗深入到电解槽的高温电解液中捞取残渣时，抓斗在打开或闭合过程中底部产生上下垂直位移，导致电解池底部边缘部分的残渣捞取不到，同时因为这种垂直位移的产生容易使抓斗底部直接触碰到电解槽底部，久而久之造成对电解池底部的损坏。At present, there is a common situation in the slag grabbing bucket in the aluminum electrolysis lifting equipment: when the grab bucket goes deep into the high-temperature electrolyte of the electrolytic tank to pick up the residue, the bottom of the grab bucket will vertically move up and down during the opening or closing process, resulting in electrolysis. The residue at the edge of the bottom of the pool cannot be picked up, and at the same time, because of the vertical displacement, the bottom of the grab bucket will directly touch the bottom of the electrolytic cell, which will cause damage to the bottom of the electrolytic cell over time.
发明内容：Invention content:
本发明的目的在于提供一种结构简单，安全耐用，且能更大程度捞取残渣的利用曲柄滑块补偿机构实现铝电解捞渣抓斗底部平移的设计方法。The purpose of the present invention is to provide a simple structure, safe and durable design method that uses the crank slider compensation mechanism to realize the translation of the bottom of the aluminum electrolysis slag grab that can fish the residue to a greater extent.
本发明解决现有技术问题所采用的技术方案：一种利用曲柄滑块补偿机构实现铝电解捞渣抓斗底部平移的设计方法，包括气缸、支撑架、平衡梁以及左右抓斗，其特征在于液压升降柱底部与平衡梁左端或右端接连，平衡梁通过连杆与支撑架上梁上的滑块连接；左右抓斗分别通过左右挂板连接在支撑架下梁的两侧，左抓斗或右抓斗通过驱动板与气缸活塞杆连接，同时左抓斗或者右抓斗连接有两个驱动杆，一个驱动杆与支撑架上梁上的滑块连接，另一个驱动杆与右抓斗或左抓斗的挂板连接；气缸尾部与支撑架的左侧或者右侧连接。The technical solution adopted by the present invention to solve the existing technical problems: a design method for realizing the translation of the bottom of the aluminum electrolytic slag grab by using the crank slider compensation mechanism, including a cylinder, a support frame, a balance beam, and a left and right grab, which is characterized in that The bottom of the hydraulic lifting column is connected to the left or right end of the balance beam, and the balance beam is connected to the slider on the upper beam of the support frame through a connecting rod; the left and right grabs are connected to both sides of the lower beam of the support frame through the left and right hanging plates, and the left grab The right grab is connected to the cylinder piston rod through the drive plate, and the left or right grab is connected with two drive rods, one drive rod is connected to the slider on the upper beam of the support frame, and the other drive rod is connected to the right grab or The hanging plate of the left grab is connected; the tail of the cylinder is connected with the left or right side of the support frame.
所述平衡梁把抓斗机构延伸至液压升降柱所在垂直方向的一侧，并在抓斗闭开过程中避免与支撑架上下梁发生碰撞。The balance beam extends the grab mechanism to one side of the vertical direction where the hydraulic lifting column is located, and avoids collision with the upper and lower beams of the support frame during the closing and opening process of the grab.
所述支撑架上梁上的滑块在做平移运动时避免与支撑架侧面发生碰撞。The slider on the upper beam of the support frame avoids collision with the side of the support frame during translational movement.
所述平衡梁与支撑架上梁滑块连接的连杆在抓斗打开或闭合过程中可以支撑起支撑架、左右抓斗和气缸的重量。The connecting rod connecting the balance beam with the upper beam slider of the support frame can support the weight of the support frame, the left and right grab buckets and the cylinder during the opening or closing process of the grab bucket.
所述连接除了液压升降柱与平衡梁之间的连接为刚性连接，其余的连接均为铰连接。Except the connection between the hydraulic lifting column and the balance beam is a rigid connection, the other connections are all hinge connections.
本发明的有益效果是：通过平衡梁和支撑架上梁之间设置曲柄滑块补偿机构，实现了抓斗在打开或闭合过程中抓斗底部的平移，更大限度的捞取电解池底部的残渣，提高了捞渣效率；同时因补偿了抓斗在打开或闭合过程中抓斗底部的上下垂直位移，从而避免了抓斗底部直接触碰到电解槽底部，防止了对电解槽底部的损坏。The beneficial effect of the present invention is that: by setting the crank slider compensation mechanism between the balance beam and the upper beam of the support frame, the translation of the bottom of the grab bucket during the opening or closing process is realized, and the residue at the bottom of the electrolytic cell can be fished to a greater extent , improving the efficiency of slag removal; at the same time, because the vertical displacement of the bottom of the grab bucket is compensated during the opening or closing process, the bottom of the grab bucket is prevented from directly touching the bottom of the electrolytic tank, and damage to the bottom of the electrolytic tank is prevented.

具体实施方式：detailed description:
如图1、2所示，利用曲柄滑块补偿机构实现底部平移的铝电解捞渣抓斗设置在液压升降柱1的左侧，平衡梁2的右端固定在液压升降柱1的下部，滑块4设置在支撑架上梁3上，连杆5分别与滑块4和平衡梁2左端的销轴连接，左右抓斗8、9通过抓斗上的挂板与支撑架下梁7两侧上的销轴连接，滑块驱动杆6分别与左抓斗8的挂板和滑块4上的销轴连接，抓斗驱动杆10分别与左右抓斗8、9上的挂板销轴连接，气缸11的活塞杆与左抓斗8的挂板销轴连接，气缸11的尾部与支撑架左侧销轴连接。本发明不需另设气动控制系统，结构简单，节省能源。As shown in Figures 1 and 2, the aluminum electrolytic slag grab bucket that uses the crank slider compensation mechanism to realize the bottom translation is set on the left side of the hydraulic lifting column 1, and the right end of the balance beam 2 is fixed on the lower part of the hydraulic lifting column 1. The slider 4 is set on the upper beam 3 of the support frame, the connecting rod 5 is respectively connected with the slider 4 and the pin shaft at the left end of the balance beam 2, and the left and right grabs 8 and 9 pass through the hanging plates on the grab and the lower beam 7 of the support frame on both sides The pin shaft connection of the slider driving rod 6 is connected with the hanging plate of the left grab bucket 8 and the pin shaft on the slider 4 respectively, and the grab bucket driving rod 10 is connected with the hanging plate pin shafts on the left and right grab buckets 8 and 9 respectively. The piston rod of cylinder 11 is connected with the hanging plate pin of left grab bucket 8, and the afterbody of cylinder 11 is connected with support frame left side pin. The invention does not need additional pneumatic control system, has simple structure and saves energy.
以抓斗设置在液压升降柱左侧为例进行说明：Take the grab bucket set on the left side of the hydraulic lifting column as an example to illustrate:
当气缸11的活塞杆上行时，通过挂板拉动左抓斗8打开，左抓斗8带动抓斗驱动杆10拉动右抓斗9同步打开，左右抓斗8、9在打开过程中抓斗底部做先下降后上升的相对运动；同时左抓斗8打开时带动滑块驱动杆6拉动滑块4在支撑架上梁3上向右侧移动，连杆5在滑块4右移的带动下做顺时针转动，支撑架上下梁3、7在连杆5顺时针转动过程中先上移后下移，进而带动左右抓斗8、9做先上升后下降的相对运动；两种相对运动同时进行相互补偿促使左右抓斗8、9在打开的过程中抓斗底部始终做平移运动。When the piston rod of the cylinder 11 goes up, the left grab 8 is pulled by the hanging plate to open, and the left grab 8 drives the grab driving rod 10 to pull the right grab 9 to open synchronously, and the left and right grabs 8 and 9 are at the bottom of the grab during the opening process. Make a relative movement of descending first and then rising; at the same time, when the left grab bucket 8 is opened, it drives the slider driving rod 6 to pull the slider 4 to move to the right on the upper beam 3 of the support frame, and the connecting rod 5 is driven by the slider 4 moving to the right Rotating clockwise, the upper and lower beams 3 and 7 of the support frame first move up and then down during the clockwise rotation of the connecting rod 5, and then drive the left and right grab buckets 8 and 9 to perform a relative movement of first rising and then falling; the two relative movements simultaneously Carrying out mutual compensation impels the left and right grab buckets 8, 9 to do translational movement at the bottom of the grab buckets in the process of opening all the time.
当气缸11的活塞杆下行时，通过挂板拉动左抓斗8关闭，左抓斗8带动抓斗驱动杆10拉动右抓斗9同步关闭，左右抓斗8、9在闭合过程中抓斗底部做先下降后上升的相对运动；同时左抓斗8关闭时带动滑块驱动杆6拉动滑块4在支撑架上梁3上向左侧移动，连杆5在滑块4左移的带动下做逆时针转动，支撑架上下梁3、7在连杆5逆时针转动过程中先上移后下移，进而带动左右抓斗8、9做先上升后下降的相对运动；两种相对运动同时进行相互补偿促使左右抓斗8、9在闭合的过程中抓斗底部始终做平移运动。When the piston rod of the cylinder 11 goes down, the hanging plate pulls the left grab bucket 8 to close, and the left grab bucket 8 drives the grab bucket driving rod 10 to pull the right grab bucket 9 to close simultaneously, and the left and right grab buckets 8 and 9 grab the bottom of the bucket during the closing process. Make a relative movement of descending first and then rising; at the same time, when the left grab bucket 8 is closed, it drives the slider driving rod 6 to pull the slider 4 to move to the left on the upper beam 3 of the support frame, and the connecting rod 5 is driven by the slider 4 moving to the left Rotating counterclockwise, the upper and lower beams 3 and 7 of the support frame first move up and then down during the counterclockwise rotation of the connecting rod 5, and then drive the left and right grab buckets 8 and 9 to perform relative movements that first rise and then descend; the two relative movements simultaneously Carrying out mutual compensation impels the left and right grab buckets 8, 9 to do translational movement all the time at the bottom of the grab buckets in the process of closing.
