The invention discloses a device for a hoisting beam to pass through a bend. The device for the hoisting beam to pass through the bend includes a load beam, a main beam bend passing device, a load beam bend passing device, a lifting beam bend passing device, a lifting beam and a main beam; the main beam bend passing device includes a tie rod and a coupling, and the tie rod and the coupling are connected by a spherical surface; the load beam bend passing device includes a pulley one, a pulley limiting stopper one, and a load beam hook assembly; the pulley one and the pulley limiting stopper oneare installed on the main beam, the upper end of the load beam hook assembly is connected to the lower end of the pulley one through a chain, and the lower end of the load beam hook assembly is connected to the load beam in a shaft connection; and the lifting beam bend passing device includes a pulley two and a pulley limiting stopper two. The degree of freedom of the device for the hoisting beamto pass through the bend enables the rectangle formed by a cross beam and the lifting beam to be bent into a fan shape when passing through the bend, so as to ensure that the hoisting beam passes smoothly through the bent; and the flexible connection of the chain under the cross beam ensures that the hoisting beam goes up and down a ramp.
本发明公开了一种起吊梁过弯道装置,包括载重梁、主横梁过弯道装置、载重梁过弯装置、提升梁过弯装置、提升梁和主横梁,主横梁过弯道装置包括拉杆和联轴器,所述拉杆和联轴器之间通过球面连接;所述载重梁过弯装置包括滑车一、滑车限位器一和载重梁挂钩总成,所述滑车一和滑车限位器一安装在主横梁上,所述载重梁挂钩总成上端通过链条连接在滑车一的下方,所述载重梁挂钩总成的下端以轴连接的方式连接载重梁;所述提升梁过弯装置包括滑车二和滑车限位器二。本发明的自由度使得十字梁和提升梁组成的矩形在过弯道时可以弯曲为扇形,保证起吊梁顺利通过弯道,十字梁下方的链条柔性连接保证起吊梁上下坡道。
