Description

吊装时销杆能自锁脱钩时销杆能自动脱扣的卸扣
技术领域
 本发明主要用于建筑工程吊装使用,属于建筑工程施工吊装工具领域。
背景技术
 我国目前使用的吊装卸扣都需要人工装入卸扣销杆,人工卸岀卸扣销杆,特别是吊装柱时,吊钩与卸扣都在柱的上端,当下端的柱脚已固定,需要人工爬到柱的上端卸下卸扣的销杆,既危险又费力,目前已申请的专利是用绳索由人工在地面拉出高空的销杆,吊装时,绳索在高空可能会绊到其它构件,会将销杆强行拉出从而发生危险。
发明内容
本发明解决了上述问题,它主要由卸扣(1)、销杆(3)、弹簧A(4)、弹簧B(5)、插销(6)、弹片(7)组成;吊装时,手推销杆(3)的手柄(9)将销杆(3)推入就位,此时弹簧A(4)处于伸长状态,将插销(6)下拉插入销杆(3)的环形槽(8)内,同时弹簧B(5)处于伸长状态,起吊后,弹片(7)在绑柱子的钢丝绳(16)的压力下向下动作带动插销(6)卡住销杆(3);卸扣时,绑柱子的钢丝绳(16)无吊物重力,弹簧B(5)回缩并拉出插销(6),弹簧A(4)回缩拉回销杆(3),完成卸扣动作。
本发明主要由卸扣(1)、销杆(3)、弹簧A(4)、弹簧B(5)、插销(6)、弹片(7)组成;卸扣(1)又由筒室(2)、孔B(12)、孔C(13)、长条孔(14)、U形环(17)组成,U形环(17)有孔B(12)、孔C(13),筒室(2)的开口端固定在U形环(17)的右端,筒室(2)的前后均有长条孔(14);销杆(3)又由圆杆(18)、环形槽(8)、手柄(9)组成,圆杆(18)的左端有环形槽(8),手柄(9)固定在圆杆(18)的右端;弹片(7)有孔A(10);插销(6)有U形槽(11);弹簧A(4)安装在筒室(2)内,弹簧A(4)的右端与筒室(2)的右端内壁固定,弹簧A(4)的左端与圆杆(18)的右端固定,弹簧B(5)的上端与卸扣(1)的U形环(17)左侧上端固定,弹簧B(5)的下端与插销(6)的上端固定,弹片(7)的右端与U形环(17)的右侧内壁固定,弹片(7)的左端上端与插销(6)的下端固定,弹片(7)的孔A(10)穿过U形环(17)的左侧杆,销杆(3)安装在筒室(2)内,并可穿过U形环(17)的孔B(12)及孔C(13),销杆(3)的手柄(9)穿过筒室(2)的前后两个长条孔(14),手推手柄(9)可带动销杆(3)在筒室(2)内左右运动。需说明:弹片(7)有一定的弹性。

具体实施方式
下面结合附图说明本发明的具体实施方式。
参见图5、图6,卸扣(1)由筒室(2)、孔B(12)、孔C(13)、长条孔(14)、U形环(17)组成;参见图7、图8,销杆(3)由圆杆(18)、环形槽(8)、手柄(9)组成;参见图1、图9、图10、图11、图12,弹片(7)的孔A(10)穿过U形环(17)的右侧杆,其上端与插销(6)的下端固定,其余各图较容易看出各部件的关系。吊装时,将本发明U形环(17)的下端穿入绑柱子的钢丝绳(16),上端放入挂吊钩的钢丝绳(15),这是建筑工程吊装时常见的安装钢丝绳的方法,人工将销杆(3)的手柄(9)沿卸扣(1)的长条孔(14)向左推,销杆(3)的圆杆(18)会依次穿过U形环(17)的孔C(13)及孔B(12)直到销杆(3)的环形槽(8)露出U形环(17)的左侧外,此时弹簧A(4)处于伸长状态,再人工向下推插销(6),使插销(6)的U形槽(11)插入销杆(3)的环形槽(8)内,此时弹簧B(5)处于伸长状态;起吊重物后,弹片(7)在绑柱子的钢丝绳(16)的压力下向下动作带动插销(6)紧紧卡住销杆(3);当吊装柱子的柱脚安装就位,需卸扣时,吊车的吊钩松钩,绑柱子的钢丝绳(16)无吊物重力作用失去对弹片(7)向下的压力,弹片(7)会向上回弹,同时弹簧B(5)回缩并拉出插销(6),此时弹簧A(4)回缩拉回销杆(3),完成卸扣动作,当销杆(3)拉回筒室(2)后,卸扣会由于自重力脱落,并随绑柱子的钢丝绳(16)掉落地面。
