Description
技术领域technical field
本发明涉及悬式绝缘子领域，具体涉及一种悬式绝缘子综合参数检测装置及检测方法。The invention relates to the field of suspension insulators, in particular to a comprehensive parameter detection device and detection method for suspension insulators.
背景技术Background technique
悬式绝缘子是电力传输中一个重要的部件，该部件的性能要求以结构高度、径向尺寸、径向尺寸波动、轴向尺寸波动、锁紧销拉力等方式给出。在厂家生产检验和使用单位接收检测时这些尺寸都是关注要点。Suspension insulator is an important part in power transmission. The performance requirements of this part are given in terms of structural height, radial dimension, radial dimension fluctuation, axial dimension fluctuation, locking pin tension, etc. These dimensions are the main points of attention during the production inspection of the manufacturer and the acceptance inspection of the user unit.
目前测量方式多采用手动测量，借助皮尺、直尺等初级测量工具及拉线位移传感器、手持式激光测距仪等工具进行测量。对于一个绝缘子的测量往往需要大量的时间，效率比较低下，绝缘子一般质量较大，因此测量的劳动强度也较大。而且测量过程对操作人员的技术水平要求较高，测量过程中人为因素较大，测量数据存在较大波动。以上这些因素极大的制约着绝缘子出厂检验和使用方的验货抽检数量，不利于产品质量的稳定和保证。At present, most of the measurement methods are manual measurement, with the help of primary measurement tools such as tape measure and ruler, as well as pull wire displacement sensors, hand-held laser rangefinders and other tools for measurement. The measurement of an insulator often takes a lot of time, and the efficiency is relatively low. Generally, the mass of an insulator is relatively large, so the labor intensity of the measurement is also relatively high. Moreover, the measurement process has high requirements on the technical level of the operators, the human factors are relatively large in the measurement process, and there are large fluctuations in the measurement data. The above factors greatly restrict the quantity of insulator factory inspection and inspection and random inspection by the user, which is not conducive to the stability and guarantee of product quality.

The measurement directions of the two first range finders are horizontally facing each other, and the two first range finders The distance meter moves synchronously; it also includes a horizontal guide rail arranged inside the frame, the long axis of the horizontal guide rail intersects with the connection line between the tensioning device and the rotating mechanism, and the second distance meter that can move along the horizontal guide rail is arranged on the horizontal guide rail , the horizontal guide rail is located below the area between the tensioning device and the rotating mechanism, and the measurement direction of the second rangefinder is vertically upward.
针对现有技术中悬式绝缘子检测效率低、误差大、测量精度不稳定的问题，本发明提出了一种悬式绝缘子综合参数检测装置，在框架内固定有自由端朝下的张紧装置，张紧装置的下端挂接悬式绝缘子的上部帽窝，待检测的悬式绝缘子下端安装在旋转机构上，即悬式绝缘子安装在旋转机构和张紧装置之间，由旋转机构带动悬式绝缘子转动。张紧装置与旋转机构之间的区域为安装悬式绝缘子的区域，该区域两侧分别设置一条竖直导轨，用于安装第一测距仪，两个第一测距仪的测量方向水平正对，即是两个第一测距仪构成一组对射的测距仪。两个第一测距仪同步运动，以确保两个测距仪始终处于相同的水平面上进行测量。两个测距仪在各自的导轨上同步运动采用现有的同步方式，比如通过一个控制器件如交流接触器、继电器等即能实现，或是通过同步运动的连杆机械式的控制也能实现，因此在本发明中不作具体限定。还包括设置于框架内部的水平导轨，水平导轨设置在安装悬式绝缘子的区域的下方。水平导轨的长轴线，与张紧装置和旋转机构的连线相交，由于张紧装置和旋转机构的连线过悬式绝缘子的轴线，因此即是水平导轨的长轴过悬式绝缘子的轴线，以确保水平导轨所在直线为悬式绝缘子的直径方向，从而确保水平导轨上的第二测距仪沿着悬式绝缘子的径向进行移动。第二测距仪的测量方向竖直向上，从而对安装在张紧装置和旋转机构之间的悬式绝缘子的底部进行扫描测量，扫描出悬式绝缘子底部不规则表面的凹凸排布情况。Aiming at the problems of low detection efficiency, large error and unstable measurement accuracy of suspension insulators in the prior art, the present invention proposes a comprehensive parameter detection device for suspension insulators, in which a tensioning device with the free end facing downward is fixed in the frame. The lower end of the tensioning device is hung on the upper cap of the suspension insulator, and the lower end of the suspension insulator to be tested is installed on the rotating mechanism, that is, the suspension insulator is installed between the rotating mechanism and the tensioning device, and the rotating mechanism drives the suspension insulator turn. The area between the tensioning device and the rotating mechanism is the area where suspension insulators are installed, and a vertical guide rail is arranged on both sides of this area for installing the first range finder, and the measuring directions of the two first range finders are horizontally aligned. Yes, that is, the two first range finders form a set of range finders that are facing each other. The two first range finders move synchronously to ensure that the two range finders are always on the same horizontal plane for measurement. The synchronous movement of the two rangefinders on their respective guide rails adopts the existing synchronous method, such as through a control device such as an AC contactor, a relay, etc., or through the mechanical control of a connecting rod that moves synchronously. , so it is not specifically limited in the present invention. It also includes a horizontal guide rail arranged inside the frame, and the horizontal guide rail is arranged below the area where the suspension insulator is installed. The long axis of the horizontal guide rail intersects the connection line between the tensioning device and the rotating mechanism. Since the connection line between the tensioning device and the rotating mechanism passes through the axis of the suspension insulator, it is the long axis of the horizontal guide rail passing through the axis of the suspension insulator. To ensure that the straight line where the horizontal guide rail is located is the diameter direction of the suspension insulator, thereby ensuring that the second rangefinder on the horizontal guide rail moves along the radial direction of the suspension insulator. The measuring direction of the second rangefinder is vertically upward, so as to scan and measure the bottom of the suspension insulator installed between the tensioning device and the rotating mechanism, and scan out the arrangement of irregularities on the bottom of the suspension insulator.

Since the horizontal distance between the two first range finders is always constant, the distance to the suspension insulator measured by each first range finder is subtracted from the distance between the two first range finders, That is, the radial dimension data of the suspension insulator can be obtained. In addition, the second rangefinder moving back and forth in the radial direction scans and measures the bottom of the suspension insulator, and scans the irregular surface of the bottom of the suspension insulator.
