Hoisting frame used for steel wire rope lifting and capable of being folded and retracted

Abstract

The invention discloses a hoisting frame used for steel wire rope lifting and capable of being folded and retracted. The hoisting frame comprises lower supporting pieces, an outer pipe, upper supporting pieces and auxiliary supporting transverse pipes; the bottom end of the outer pipe is connected with supporting rods through the lower supporting pieces; the supporting rods are hinged to the lower supporting pieces through two pins; springs are mounted in the lower supporting pieces; the two pins are connected through the springs; a middle pipe is connected to top end of the outer pipe; an inner pipe is sleeved with the upper end of the middle pipe; the inner pipe and the middle pipe are connected through a transistor stretching pin; and the upper supporting pieces are welded to the top of the inner pipe. The cost is low, lightness is achieved, folding can be achieved, convenience and firmness are achieved, the weight and cost are reduced, and retracting is convenient; and the auxiliary supporting transverse pipes are arranged on main supporting transverse pipes in a sleeving mode and can move leftwards and rightwards, drawing, pulling and extending can be conducted, after being retracted and folded, the auxiliary supporting transverse pipes are small in size and convenient to carry, and the auxiliary supporting transverse pipes are suitable for being used for the hoisting frame during mounting of gypsum boards, lamps, air conditioners, water heaters, electric laundry racks and the like.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a foldable and shrinkable wire rope lifting frame. Background technique [0002] Currently. There are many kinds of clothes drying racks used by people, and the traditional clothes drying racks take up a lot of space and cannot meet people's various needs for drying clothes. The existing electric drying rack has the problems of complicated structure, high price and difficult installation. In particular, the lifting frame of the existing electric clothes rack is manually carried up during installation, which is time-consuming and labor-intensive, and the labor intensity is high; the lifting frame of the gypsum board is used, but the structure is huge and inconvenient to carry. Therefore, a foldable The retractable wire rope lifting frame meets the needs of use. Contents of the invention [0003] The object of the present invention is to provide a foldable and shrink...
