The invention discloses a novel centrally-arranged loop chain elevator which comprises an upper lifting hook, a lower lifting hook, a lifting chain, a wall-attached connecting piece, an upper liftingpoint wheel set, a lower lifting point wheel set, a tension spring and a turn buckle. The upper lifting hook is used for being hung on an upper lifting point of a climbing frame. The lower lifting hook is used for being hung on a lower lifting point of the climbing frame. An upper fixing point of an electric hoist head is connected to the lower end of the wall-attached connecting piece in a hingedmanner. A middle chain wheel is additionally arranged on one side of the electric hoist head in a rotating manner. After one end of the lifting chain is hinged to a lower fixing point of the electrichoist head, the other end of the lifting chain is hinged to the lower end of the turn buckle after sequentially passing through a chain wheel in the lower lifting point wheel set, a guide chain wheelin the electric hoist head, the middle chain wheel and a chain wheel in the upper lifting point wheel set. According to the elevator, the electric hoist head is arranged at the lower end of the wall-attached connecting piece forward, a rain cover can be installed conveniently, and additional extrusion stress generated on a vertical rod of the climbing frame in the elevating process of the climbing frame can be avoided.
本发明公开了一种新型中置环链提升机,包括上吊钩、下吊钩、起重链条、附墙连接件、上吊点轮组、下吊点轮组、拉簧和花篮螺栓,上吊钩用以悬挂在爬架上吊点上;下吊钩用以悬挂在爬架下吊点上;电动葫芦头的上固定点与附墙连接件的下端铰连接,该电动葫芦头的一侧可转动地增设有中间链轮;起重链条的一端铰接于电动葫芦头的下固定点处后,起重链条的另一端依次经过下吊点轮组中链轮、电动葫芦头中导链轮、中间链轮、上吊点轮组中链轮后铰接于花篮螺栓的的下端。本发明将电动葫芦头正设于附墙连接件下端,能够方便防雨罩的安装,能够避免爬架提升时对爬架立杆产生附加挤压应力。
