Deck crane and rear anchoring mechanism thereof
The invention provides a rear anchor mechanism which is arranged at the rear end of a rear pressing rod of a supporting truss and comprises a pull-down piece used for being connected with a lifting lug pre-welded to a bridge deck slab, the top of the pull-down piece is connected with a connecting screw rod through a connecting conversion structure, and the connecting screw rod penetrates through the rear end of the rear pressing rod and is fixed to the rear pressing rod through a nut. And the mechanism further comprises a balance weight part which is used for increasing the balance weight of the supporting truss. The connecting strength of the bridge deck crane and a bridge deck is improved by being connected with the bridge deck plate and the welded lifting lugs, meanwhile, the balance weight parts are further arranged on the supporting trusses, the base of the bridge deck crane and the lifting end of the bridge deck crane can be stressed in a balanced mode, the structural stability of the bridge deck crane is improved, and the bridge deck crane is suitable for hoisting objects with large loads so as to achieve the anti-overturning effect.
本申请提供一种后锚机构，设于支撑桁架的后压杆后端，包括用于与桥面板上预焊接的吊耳连接的下拉件，所述下拉件的顶部通过连接转换结构连接有连接螺杆，所述连接螺杆贯穿后压杆的后端并通过螺母与后压杆固定；还包括用于增加支撑桁架配重的配重部。通过与桥面板与焊接的吊耳连接，以提高桥面吊机与桥面的连接强度，同时还在支撑桁架上设置配重部，可使桥面吊机的底座与其提升端受力平衡，以提高桥面吊机的结构稳定性，适用于吊装荷载较大的物件的情况，以起到防倾覆的作用。
