Abstract

一种输电线路铁塔倾斜修正后用的加长螺栓，包括带外螺纹的螺栓体，螺栓体的端部设置有扩大端，在扩大端设置有与地脚螺栓相配的内螺纹。所述螺栓体的直径与地脚螺栓的直径相同，扩大端的内螺纹顶牙到扩大端外表面的距离大于地脚螺栓直径的1/3。采用上述技术方案，本实用新型有以下优点：本实用新型对原有的地脚螺栓进行加长，并且可保证连接强度复合要求，由于螺栓体直径与地脚螺栓直径相同，只在螺栓体的端部设置扩大端，用于连接地脚螺栓，保证连接强度的同时节省原料。本实用新型结构简单、使用方便，可以在不停电的情况下，迅速对原有的地脚螺栓进行加长，保证了输电线铁塔的有效固定。

Description

输电线路铁塔倾斜修正后用的加长螺栓
技术领域
本实用新型涉及一种电力设备维修装置，特别是一种输电线铁塔倾斜修正后用的加长螺栓。
背景技术
输电线铁塔是输电线路中的重要组成部分，它主要是由角钢组焊成的四棱锥形的塔状结构，其底部通过地脚螺栓固定在地基上。由于地质条件和铁塔地基的变化，会造成输电线铁塔的倾斜，给输电线路的安全带来了很大的安全隐患。当输电线铁塔出现倾斜时，需要将固定输电线铁塔需要调整高度一侧的地脚螺栓上的螺母松开，向上抬起该侧的输电线铁塔，进行垂直度的调整。由于根据规定，地脚螺栓伸出地面的长度是一定的，当调整的高度大于地脚螺栓的有效长度时，原有的地脚螺栓就无法起到固定作用。
发明内容
本实用新型的目的在于克服上述不足提供一种输电线路铁塔倾斜修正后用的加长螺栓。
本实用新型的目的通过以下技术方案来实现：
一种输电线路铁塔倾斜修正后用的加长螺栓，包括带外螺纹的螺栓体，螺栓体的端部设置有扩大端，在扩大端设置有与地脚螺栓相配的内螺纹。
上述输电线路铁塔倾斜修正后用的加长螺栓，所述螺栓体的直径与地脚螺栓的直径相同，扩大端的内螺纹顶牙到扩大端外表面的距离大于地脚螺栓直径的1/3。
采用上述技术方案，本实用新型有以下优点：本实用新型对原有的地脚螺栓进行加长，并且可保证连接强度复合要求，由于螺栓体直径与地脚螺栓直径相同，只在螺栓体的端部设置扩大端，用于连接地脚螺栓，保证连接强度的同时节省原料。本实用新型结构简单、使用方便，可以在不停电的情况下，迅速对原有的地脚螺栓进行加长，保证了输电线铁塔的有效固定。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
如图1所示的一种输电线路铁塔倾斜修正后用的加长螺栓，包括带外螺纹的螺栓体3，螺栓体3的端部设置有扩大端2，在扩大端2设置有与地脚螺栓相配的内螺纹1。螺栓体3的直径与地脚螺栓的直径相同，扩大端的内螺纹顶牙到扩大端外表面的距离大于地脚螺栓直径的1/3。
当调整完输电线铁塔的倾斜后，将双头螺栓穿过输电线铁塔上的螺纹孔，使内螺纹1与地脚螺栓连接固定，通过与外螺纹配套的螺母将输电线铁塔紧固在基础上。
