The loading and unloading devices can be arranged in two groups, which are respectively arranged at the loading site and the unloading site, and do not need to be transferred along with the hoisting. After the materials are transferred from the hanging basket, the hanging basket can be immediately hoisted to a loading place by the tower crane, and the materials are hoisted by the previous hoisting equipmentIn the meantime, materials can be stacked on an outer roller way of a loading place, and when an empty hanging basket is loaded to the loading place by a tower crane, the second loading and hoisting can be rapidly carried out. A transition plate can be arranged between the outer roller way and the inner roller way 16 to prevent the materials from falling when being pushed to the butt joint position. The inner roller table 16 and the outer roller table can adopt diameters

A steel belt conveyor roller bed with the length of 1.2m is embedded in a basket base 42 channel steel at intervals of 20mm, and the top of the steel belt conveyor roller bed is 20mm higher than the surface of the channel steel. The outer roller way is preferably slightly longer than the hanging basket by 200mm, and the stroke of the linear driving mechanism is preferably slightly longer than the hanging basket by 400 mm.

The quick-loading basket 10 may be provided with only one loading and unloading opening through which both the load and unload materials pass, or may be provided with a loading opening 18 and a discharge opening 19, respectively, through which the load is pushed in through the loading opening 18 and the unload material is pushed out through the discharge opening 19. The latter is adopted in the embodiment shown in fig. 3, wherein the loading and unloading port comprises a charging port 18 and a discharging port 19, the charging port 18 and the discharging port 19 are respectively arranged at the front end and the rear end of the basket frame 11, and the charging port 18 and the discharging port 19 are respectively provided with an opening and closing door. The advantage of this kind of mode lies in, and the effort to the material is thrust through the mode of propelling and propelling, is more favorable to controlling the motion of material to loading and unloading can push in when only adopting a loading and unloading mouth, and can only pull out when unloading, and loading and unloading are thrust and pulling force respectively, and the relative control degree of difficulty will be some more.

the stroke of the first linear drive mechanism 22 and the second linear drive mechanism 32 is greater than the length of the knock-out basket 10, where the length of the knock-out basket 10 is the length in the material conveying direction.

The specific hoisting method comprises the following steps:

stacking the materials on a first outer roller table 21;

butting the material charging port 18 of the fast loading and unloading basket 10 with the butt joint end of a first outer roller bed 21;

opening the charging port 18 of the rapid loading and unloading basket 10, and pushing the stacked materials from the first outer roller way 21 onto the inner roller way 16 of the rapid loading and unloading basket 10 by the first linear driving mechanism 22;

closing and locking the opening and closing doors of the charging opening 18 and the discharging opening 19 of the fast loading and unloading basket 10, and hoisting the fast loading and unloading basket 10 together with the materials in the fast loading and unloading basket to a specified discharging place by using hoisting equipment;
