The invention discloses a portal frame for hoisting based on elevator machining. The portal frame comprises a crane, a steel rail is fixedly connected to the bottom of the crane, chain boxes are slidably connected to the left side and the right side of the bottom of the steel rail, and transmission shafts are movably connected to the bottom of the left side of the inner wall of each chain box and the bottom of the right side of the inner wall of each chain box through bearing seats; and the surfaces of the transmission shafts are sleeved with a winding wheel, the bottom of the winding wheel penetrates to the bottoms of the chain boxes, a steel wire is wound on the surface of the winding wheel, the top of an inner cavity of the chain box is transversely and movably connected with a locking mechanism through a bearing seat, and the left side and the right side of the chain box are movably connected with transmission mechanisms through bearing seats. The portal frame solves the problem that an existing portal frame does not have a locking effect, so that a lifted object is overloaded and is prone to sliding down and touching the ground, the machining cost loss of a user is reduced, the working safety of the portal frame is improved, and the practicability of the portal frame is also improved.
本发明公开了一种基于电梯加工吊装用龙门架,包括吊机,所述吊机的底部固定连接有钢轨,所述钢轨底部的左侧和右侧均滑动连接有锁链箱,所述锁链箱内壁左侧的底部和内壁右侧的底部均通过轴承座活动连接有传动轴,所述传动轴的表面套接有收卷轮,所述收卷轮的底部贯穿至锁链箱的底部,所述收卷轮的表面缠绕有钢丝,所述锁链箱内腔的顶部通过轴承座横向活动连接有锁死机构,所述锁链箱的左侧和右侧均通过轴承座活动连接有传动机构。本发明解决了现有的龙门架不具有锁死作用,导致起吊物体过载容易出现滑落触地的问题,减少了使用者加工的成本损耗,增加了龙门架工作的安全性,也提高了龙门架的实用性。
