The specific manufacturing method of the detachable portable lifting device comprises the following steps:

and determining the height and span of the steel structure bracket according to the actual space conditions of the hoisting field, and determining the installation position of the I-steel guide rail on the steel structure bracket.

And (3) calculating structural strength according to the maximum hoisting weight possibly borne by the hoisting device, and selecting a proper type of channel steel or I-steel to manufacture the steel structure bracket.

In order to facilitate the disassembly and the transfer of the steel structure support, all components of the steel structure support are connected by bolts.

The I-steel guide rail is locked and fastened on the lower side of the top cross beam of the steel structure support by using the fastener, the position of the I-steel guide rail can be selected and adjusted according to actual hoisting requirements, and the I-steel guide rail can be eccentrically arranged on one side of the steel structure support or can be positioned in the middle of the steel structure support.

The electric hoist is arranged on the I-steel guide rail, can move along the I-steel guide rail, and realizes the functions of hoisting and transferring the components in a certain range.

The base of the steel structure bracket is fixed on the existing steel structure or concrete floor in the factory building through bolts, or universal rollers are arranged on the base, so that the lifting device can horizontally move in a certain range.

The utility model has the following advantages:

(1) The height dimension and the span dimension can be flexibly adjusted according to the use scene, the problem of component lifting in a narrow region of a factory building space is solved, and the defect that a travelling crane or a crane cannot be unfolded or has a blind area in the narrow region of the space is overcome.

(2) When the crane is applied to a scene that the weight of a part is not large but repeated lifting is needed for many times, the lifting efficiency and the convenience are superior to those of a crane and a crane which frequently use a large load.

(3) The device is simple to disassemble and assemble, has adjustable height and span, has low requirements on installation sites, and can be transferred and recycled among different working areas, so that the device has wide adaptability and high utilization rate.

(4) The universal roller is installed on the base to realize the integral movement, and the long-distance lifting of the component is realized by the small structural size of the lifting device.
