Abstract

本发明公开一种安全吊钩，旨在提供一种能防止钢丝绳脱钩，且操作方便的吊装用吊钩。它包括滑轮、框架、吊钩、轴承外圈、轴承内圈、轴承内套、连接杆、锁杆。轴承内套下端伸出框架外，其与轴承内圈过盈配合并活套在吊钩柄部；轴承外圈与框架固定，连接杆的一端与轴承内套铰接，另一端与锁杆的一端铰接，所述锁杆的中部与所述吊钩铰接。起吊时，框架带动轴承、轴承内套沿吊钩柄部上移，连接杆也随之上移，与之铰接的锁杆绕锁杆与吊钩的铰接点转动，使锁杆扣紧吊钩；放下吊装物至地面时，框架带动轴承、轴承内套沿吊钩柄部下移，连接杆随之下移，带动锁杆绕锁杆与吊钩铰接点转动，松开扣紧的吊钩，放下钢丝绳。本发明可用于吊机、起重机等起吊设备上的吊钩。

Description

安全吊钩
技术领域
本发明涉及一种吊装用吊钩。
背景技术
吊装用吊钩，大多无防止钢丝绳脱钩的装置，起吊时易发生因脱钩造成安全事故或物品毁损。
发明内容
本发明克服现有技术的上述不足，提供一种能防止钢丝绳脱钩，且操作方便的吊装用吊钩。
本发明采用如下技术方案：一种安全吊钩，由滑轮、框架、吊钩、轴承外圈、轴承内圈、轴承内套、连接杆、锁杆组成。轴承内套与轴承内圈过盈配合，并活套在吊钩柄部，其下端伸出框架外，与连接杆的一端铰接；连接杆的另一端与锁杆的一端铰接，锁杆的中部与吊钩铰接；轴承外圈固定在框架上，滑轮的轴也固定在框架上。
起吊时，滑轮带动框架，框架上的轴承外圈带动轴承内圈、轴承内套沿吊钩柄部上移，连接杆也随之上移，与之铰接的锁杆绕锁杆与吊钩的铰接处转动，使锁杆扣紧吊钩；当放下吊装的物品至地面时，框架带动轴承外圈、轴承内圈、轴承内套沿吊钩柄部下移，连接杆随之下移，带动锁杆绕锁杆与吊钩的铰接点转动，松开扣紧的吊钩，使钢丝绳脱开吊钩。
本发明的有益效果是有效防止作业时钢丝绳脱离吊钩，保证地面人员安全，防止起吊物品因脱钩而毁损。
附图说明
附图是本发明的示意图。
具体实施方式
下面结合附图和具体实施方式对本发明作进一步描述：
滑轮1的轴固定在框架7上，轴承6的外圈也固定在框架7上；轴承内套3活套在吊钩2的柄部，轴承内套3的下端伸出框架7处，与连接杆4的一端铰接，连接杆4的另一端与锁杆5的一端铰接，锁杆5的中部与吊钩2铰接。
当吊机拉动滑轮1，带动框架7、轴承6沿吊钩2的柄部上移起吊时，连接杆4也随之上移，与连接杆4铰接的锁杆5绕与吊钩2的铰接点转动，轴承6碰到吊钩2柄部的上止点时，停止沿吊钩2的柄部上移，锁杆5正好扣紧吊钩2。
当放下起吊的物品至地面时，轴承6连同框架7沿吊钩2的柄部下移，经连接杆4使锁杆5打开扣紧的吊钩2，以使钢丝绳脱开吊钩2。
