Abstract

本实用新型涉及起重机上的一种安全装置,特别是副臂防后倾自动就位装置,它包括本体,位于本体一端的带有重锤的调节臂,位于本体另一端上的连接销孔,以及设置在本体和调节臂交接处外侧的限位槽。它主要应用在履带起重机上。

Description

副臂防后倾自动就位装置
技术领域
本实用新型涉及履带起重机,特别是涉及的一种履带起重机上的安全装置。
背景技术
在履带式起重机产品中,安全措施的采用极其重要,在塔式工况中,由于配置有副臂变幅桅杆,所以副臂的防止后倾必须采用可靠的措施。特别在高空作业时受风的影响可能会使副臂发生后倾的危险性增大,从而影响整个起重机的稳定及安全。
发明内容
为了解决履带起重机副臂存在的后倾危险,本实用新型提供一种副臂防后倾自动就位装置,它包括本体,位于本体一端的带有重锤的调节臂,位于本体另一端上的连接销孔,以及设置在本体和调节臂交接处外侧的限位槽。
本实用新型的有益效果是:结构简单,制造成本低,且可有效防止履带起重机副臂后倾。
附图说明
图1为本实用新型的结构示意图;
图2为本实用新型在履带起重机上的装配位置。
具体实施方案
下面结合附图对本实用新型作进一步说明:
如图1所示,本实用新型包括本体1,位于本体一端的带有重锤4的调节臂3,位于本体另一端上的连接销孔2,以及设置在本体1和调节臂3交接处外侧的限位槽5。
图2为本实用新型在履带起重机上的装配位置,工作时,副臂7可以绕其连接销轴在铅垂面内摆动,由于本实用新型中重锤4的作用,当副臂由水平状态逆时针摆动时,本实用新型会绕连接销孔2摆动,在一定范围内始终保持图2所示状态,此时本实用新型不起限位作用。副臂7继续摆动到限位装置接触本实用新型时,副臂7便带着本实用新型一起摆动,当摆动至限位槽5与防倾杆6杆头啮合时,本实用新型便起限位作用,阻止副臂7进一步后倾。
