Description

一种电梯用可调节导轨支架 技术领域
本发明涉及一种导轨支架，具体涉及一种电梯用可调节导轨支架， 属于电动升降装置技术领域。
背景技术
据申请人了解，现有连接电梯导轨的导轨支架由四个角钢组成一矩形框架。现场安装时，由于导轨底面至电梯井道壁的距离是不确定的，故必须根据每个项目的具体井道尺寸进行切割、焊接制作导轨支架。不仅给施工带来了不便，而且造成了材料浪费。
检索发现，申请号为201010185162.9的中国专利申请公开了一种电梯导轨支架的固定结构，包括导轨支架、固定所述导轨支架的井道壁，井道壁为砖墙，井道壁的内侧和外侧分别设置有墙夹板，导轨支架固定在位于内侧的所述墙夹板上，位于内侧和外侧的所述墙夹板通过螺杆组件夹紧在井道壁上。该方案只改变了支架与井道壁的固定连接方式，仍然缺少调节环节。尤其是，无论导轨底面至电梯井道壁的距离如何变化，支架与井道壁固定连接件的间距不能相应改变，结果当支架与井道壁的间距较大时，即使导轨受到的侧向力与间距较小时相同，由于间距增大导致力臂加大，因此固定连接件受到的力矩增加，其受力状态不够理想。
 技术问题
本发明的首要目的是：提供一种电梯用可调节导轨支架，从而方便施工，节省材料。
本发明进一步的目的是，提供一种可以随导轨底面至电梯井道壁的距离变化，相应调节支架与井道壁固定连接件间距的电梯可调节导轨支架，从而相应抑制固定连接件受到的力矩，使其始终处于理想的受力状态。
 技术解决方案
为了达到上述首要目的，本发明的电梯可调节导轨支架由固定支架、调节支架、导轨压板构成；所述固定支架包括左、右角钢形支架；所述调节支架由角钢形主体段分别向两侧倾斜方向折弯延伸出第一支撑臂和第二支撑臂，形成三边梯形结构；所述固定支架的左、右角钢形支架，以及所述调节支架的主体段和第一、第二支撑臂分别具有水平支撑面和垂向支撑面；所述左、右角钢形支架的垂向支撑面分别制有固定连接件穿孔，所述调节支架主体段的垂向支撑面制有左、右导轨压板安装孔；所述左、右角钢形支架水平支撑面分别与第一、第二支撑臂的水平支撑面相互可调固连。
上述可调固连的方式既可以是现场调节后焊接，也可以采用沿导轨底面至电梯井道壁距离方向延伸的长槽形穿孔，调节后用紧固件固连。这样，不必根据每个项目的具体井道尺寸单独制造轨道支架，只要借助可调环节，安装时根据导轨底面至电梯井道壁的实际距离调整后固连即可，从而方便施工，节省材料。
为了提高调节支架的刚性和强度，上述主体段水平支撑面与第一支撑臂和第二支撑臂的水平支撑面折弯连接处分别搭焊加强垫片。
为了达到进一步的目的：所述第一、第二支撑臂的水平支撑面分别制有沿倾斜方向延伸的长槽形穿孔；所述左、右角钢形支架的水平支撑面分别制有圆孔。
 有益效果
这样，第一、第二支撑臂的水平支撑面形成八字形长槽孔。当根据导轨底面至电梯井道壁的距离调节固定支架与调节支架的相对位置时，在八字形长槽孔对左、右角钢形支架圆孔的引导作用下，左、右角钢形支架的间距将随着固定支架与调节支架的间距调大而相应合理增大，从而无论导轨底面至电梯井道壁的距离如何变化，固定连接件的间距将随之相应改变，从而补偿侧向力矩变化对支架刚性的影响，使之始终处于较为理想的受力状态，有助于保证电梯安全稳定的运行。不难理解，本发明第一、第二支撑臂不仅有助于提高整个支架的刚性和强度，而且便于形成八字形长槽孔，从而巧妙实现了左、右角钢形支架间距随固定支架与调节支架的间距调大而相应增大。
 附图说明
图1是本发明实施例一的立体结构示意图；
图2是本发明实施例二的立体结构示意图；
图3是图2实施例安装后的状态示意图。
 本发明的实施方式
实施例一
如图1所示，本实施例的高速电梯用可调节导轨支架包括固定支架1、调节支架2和导轨压板3。
固定支架1包括左、右两个角钢形支架1-1。调节支架2由角钢形主体段2-3分别向两侧倾斜方向折弯延伸出第一支撑臂2-1和第二支撑臂2-2，形成三边梯形结构。由于实际上直接采用角钢制作，因此固定支架1的左、右角钢形支架1-1，以及调节支架2的主体段2-3和第一、第二支撑臂2-1、2-2分别具有水平支撑面和垂向支撑面。为了提高调节支架2的刚性和强度，主体段2-3水平支撑面与第一支撑臂2-1和第二支撑臂2-2的水平支撑面折弯连接处焊接，并分别搭焊加强垫片2-4、2-5。左、右角钢形支架1-1的垂向支撑面分别制有作为固定连接件的膨胀螺栓1-2的穿孔1-1-1，且该穿孔沿水平方向延伸呈长槽形，因此具有一定的安装调节余地。
调节支架主体段2-3的垂向支撑面制有左、右导轨压板3安装孔2-3-1，用于借助紧固螺栓2-6固定导轨压板3。该安装孔也沿水平方向延伸呈长槽形，因此进一步增加了安装调节余地。
安装时，先将左、右两个角钢形支架借助膨胀螺栓固定在墙体上。再将调节支架的两端分别置于左、右角钢形支架的水平支撑面上，根据现场实际情况移动调节，确定好相对位置后，将调节支架的两端分别与固定支架焊接固连，实现左、右角钢形支架水平支撑面与第一、第二支撑臂水平支撑面的相互可调固连。
与现有的框型电梯轿厢导轨支架相比，本实施例的电梯轿厢导轨支架安装时具有多处可调环节，因此保证了导轨支架与导轨之间的良好配合，有助于提高电梯轿厢运行的稳定性。实际上，调节支架由一根角钢折弯焊接制成，因此工艺简单，具有理想的抗拉强度及刚度，十分适于高速电梯使用。
实施例二
本实施例的可调节导轨支架如图2所示，其基本结构与实施例一相同。不同之处在于，可调支架2的第一和第二支撑臂2-1、2-2的水平支撑面分别制有沿其倾斜方向延伸的长槽形穿孔，左、右角钢形支架1-1的水平支撑面分别制有圆孔。
安装时如图3所示，将调节支架2两端第一和第二支撑臂2-1、2-2的水平支撑面分别置于左、右角钢形支架1-1的水平支撑面，将两紧固螺栓分别穿过第一和第二支撑臂的长槽形穿孔，以及左、右角钢形支架的圆孔。电梯轿厢导轨5位于两个导轨压板3之间，使导轨压板3连同可调支架就位。再根据导轨底面至电梯井道壁的距离，调节左、右角钢形支架1-1圆孔相对于第一和第二支撑臂2-1、2-2上长槽形穿孔的位置。调好之后，在墙体上配钻膨胀螺栓孔，将左、右角钢形支架1-1的垂向支撑面分别借助膨胀螺栓1-2固定连接在墙体4上，再锁紧所有紧固件即可。
在以上调节过程中，当导轨底面至电梯井道壁的距离较大时，左、右角钢形支架1-1的圆孔将调向第一和第二支撑臂2-1、2-2上长槽形穿孔的外端位置，从而使分别穿过左、右角钢形支架1-1圆孔的紧固螺栓间距加大，进而使穿过左、右角钢形支架1-1垂向支撑面的两膨胀螺栓1-2间距相应加大；反之，该间距相应减小。因此，当导轨底面至电梯井道壁的距离较大，电梯导轨收到的侧向作用力可能产生更大的力矩时，由于作为固定连接件的两膨胀螺栓1-2间距相应加大，因此可以抑制力矩增大的影响，使导轨支架受力状态稳定，有助于保持其强度和刚性。
需要说明的是，上述实施例是非限制性的。除上述实施例外，本发明还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本实用新型要求的保护范围。
