Abstract

一种推土机方钢管推杆,包括杆体,杆体为方钢管,杆体前端焊接接头,杆体的后端焊接支座,杆体与支座之间焊接筋板,另外在杆体上焊接连板、前托架、加强板、后托架和后加强板。本实用新型利用一整根同等强度的方钢管代替推杆方盒,方钢管不用焊接,大大缩短了制造推杆的工时,也避免了焊接带来的缺陷,结构简单,简化推杆制造工艺,增加了推杆的强度。

Description

推土机方钢管推杆
技术领域
本实用新型涉及一种推土机推杆,尤其是一种推土机方钢管推杆。
背景技术
目前,公知的推土机推杆结构为焊接结构,具体是将四块钢板及垫块经过组对、点固、焊合、校形、二次组对、点固、焊合、清渣、校形等工序依次完成推杆方盒的焊接,然后在方盒上焊好接头、齿条、托架等其它工件。由于推杆方盒尺寸大,工件长,焊接工艺中存在工艺复杂、校形困难、清渣慢、工时长等缺点。而且焊合件不可避免地会存在裂纹、夹渣、气孔等缺陷,从而导致推杆在使用过程中可能会出现开焊、弯曲等问题。
发明内容
本实用新型的目的是提供一种推土机方钢管推杆,克服现有推杆结构制造工艺复杂和使用过程中开焊、弯曲的不足,推杆方盒完全不使用焊接技术,而且强度高,使用寿命长。
本实用新型的目的是以如下方式实现的:该推土机方钢管推杆包括杆体,杆体为方钢管,杆体前端焊接接头,杆体的后端焊接支座,杆体与支座之间焊接筋板,另外在杆体上焊接连板、前托架、加强板、后托架和后加强板。利用一整根同等强度的方钢管代替推杆方盒,方钢管不用焊接,大大缩短了制造推杆的工时,也避免了焊接带来的缺陷,增加了推杆的强度。
本实用新型结构简单,简化推杆制造工艺,增加了推杆的强度。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
参照图1,本实用新型包括杆体6,杆体6为方钢管,杆体6前端焊接接头1,杆体6的后端焊接支座9,杆体6与支座9之间焊接筋板8,另外在杆体6上焊接连板2、前托架3、加强板4、后托架5和后加强板7。
