The invention discloses a hoistway elevator for construction. The hoistway elevator comprises a building hoistway, a sky beam, a traction medium, a traction machine, a cage and a counterweight; the sky beam is connected to the top end of the building hoistway, and the traction machine is connected to the lower portion of the building hoistway; and the sky beam is fixedly connected with a friction wheel and is rotatably connected with a second guide wheel, a third guide wheel, a fourth guide wheel and a fifth guide wheel, one end of the traction medium is connected to one end of the sky beam, and the traction medium sequentially bypasses the friction wheel, the cage, the second guide wheel, the third guide wheel, a driving wheel of the traction machine, the fourth guide wheel, the fifth guide wheel and the counterweight from the end until the other end of the traction medium is connected to the bottom face of the other end of the sky beam. According to the hoistway elevator for construction, the plurality of guide wheels and the traction medium are adopted to enable the cage to be located at a movable pulley, so that the traction capacity of the traction machine is doubled, the traction efficiency is improved, and the operation safety of the elevator is improved.

    本发明公开了一种施工用井道升降机,包括建筑物井道、天梁、曳引媒介、曳引机、吊笼和对重;所述天梁连接在建筑物井道的顶端,曳引机连接在建筑物井道的下方;所述天梁上固定连接有摩擦轮和可转动连接有第二导向轮、第三导向轮、第四导向轮与第五导向轮;所述曳引媒介的一端连接在天梁的一端,且曳引媒介自该端起依次绕过摩擦轮、吊笼、第二导向轮、第三导向轮、曳引机的驱动轮、第四导向轮、第五导向轮和对重,至曳引媒介的另一端连接在天梁另一端的底面。本发明的一种施工用井道升降机,采用多个导向轮和曳引媒介使吊笼处于动滑轮处,使曳引机的曳引能力提高一倍,提高曳引效率,增加升降机运行的安全性。
