Abstract

本实用新型用于自升式塔式起重机的起重臂和平衡臂拉杆。自升式塔式起重机起重臂和平衡臂拉杆的材质都是Q235B。耗用的材料多。拉杆圆钢[3]的材质为Q345B，圆钢[3]一端是双耳板[1]，双耳板[1]之间平行相隔，圆钢[2]插入双耳板[1]，单耳板[3]在圆钢[2]另一端，圆钢[2]插入单耳板[3]。本实用新型与公知技术相比，起重臂和平衡臂拉杆圆钢的直径尺寸减小的范围在5％～46％之间。取中间值可以节约25％左右的钢材。

Description

高强度塔式起重机起拉杆
一、技术领域
本实用新型用于自升式塔式起重机的起重臂和平衡臂拉杆。
二、背景技术
自升式塔式起重机起重臂和平衡臂拉杆的材质都是Q235B。耗用的材料多。
三、实用新型内容
1.本实用新型的目的是设计一种适用高强度塔式起重机起拉杆。在自升式塔式起重机上使用的起重臂和平衡臂拉杆(见附图1、2)。经过计算把起重臂和平衡臂拉杆的材质改成Q345B材质。
2.这里主要说明高强度塔式起重机起拉杆的结构尺寸数据。把起重臂和平衡臂拉杆的Q235B的材质改成Q345B材质，用Q345的材质要节约46％以内的材料。其特征是；拉杆圆钢的材质为Q345B，圆钢一端是双耳板，双耳板之间平行相隔，圆钢插入双耳板，单耳板在圆钢另一端，圆钢插入单耳板。起重臂和平衡臂拉杆的长度尺寸、耳板的外形尺寸不变，耳板的孔尺寸不变，圆钢直径尺寸减小。圆钢直径尺寸减小的范围在5％～46％之间。
3.本实用新型与公知技术相比，起重臂和平衡臂拉杆圆钢的直径尺寸减小的范围在5％～46％之间。取中间值可以节约25％左右的钢材。
四、附图说明：附图1是塔式起重机起重臂和平衡臂拉杆主视图。附图2是塔式起重机起重臂和平衡臂拉杆俯视图。
五、具体实施方式
1.结合附图1、2描述：拉杆圆钢[3]的材质为Q345B，圆钢[3]一端是双耳板[1]，双耳板[1]之间平行相隔，圆钢[2]插入双耳板[1]，单耳板[3]在圆钢[2]另一端，圆钢[2]插入单耳板[3]。以上的零件先点焊牢后再焊接。
