A portal frame type narrow space hoisting and transferring device belongs to the technical field of hoisting machinery and comprises a steering wheel system, a lifting system, a hoisting system and a transverse driving system. Free steering and moving of the device are achieved through the 360-degree rotating and moving function of the steering wheel system. By means of the secondary hydraulic cylinder on the stand column, the device can stretch out and draw back in a large stroke in the vertical direction, and entering and exiting of a workshop and hoisting of heavy objects are facilitated; through a sprocket chain mechanism and a guide rail pulley device at the upper end of the cross beam, transverse movement of the heavy object is realized. The whole device can stretch out and draw back by 2.5 m to 3 m in the vertical direction, is not limited by the size of a factory building door opening and freely enters a narrow space for operation, free moving and transporting of the whole device in a factory building can be achieved through a steering wheel system, a chain wheel and chain mechanism is adopted for transverse movement, and stability and safety in the heavy object moving and transporting process can be guaranteed.

    一种龙门架式狭窄空间起吊移运装置,属于起重机械技术领域,包括舵轮系统、升降系统、起吊系统、横向驱动系统。通过舵轮系统的360°旋转移动功能,实现装置的自由转向和移运;通过立柱上的二级液压缸,实现装置在竖直方向进行较大行程的伸缩,便于进出厂房和起吊重物;通过横梁上端的链轮链条机构和导轨滑轮装置,实现重物的横向移动。整套装置可在竖直方向伸缩2.5~3m,不受厂房门洞尺寸限制,自由进入狭窄空间作业,采用舵轮系统可实现整套装置在厂房内部的自由移运,横向动作采用链轮链条机构,可保证移运重物过程中平稳安全。
