The barrel hoisting equipment 100 provided by the invention adopts a construction method of welding the ground and integrally lowering, and can effectively solve the problems of low construction efficiency and high safety risk existing in the underground barrel of the conventional vertical shaft 200; the hydraulic continuous lifting equipment is adopted, the occupied space is small under the same lifting tonnage, and the synchronous lowering construction precision is high; the connecting seat 114 is arranged on the inner side of the welded cylinder 300, so that the gap between the cylinder and the wall of the vertical shaft 200 is greatly reduced, and the concrete filling cost is reduced; the ring rail type steel pipe ring crane is configured, so that the steel pipe piece can be automatically conveyed to a specified installation welding area by the aid of vehicle configuration; and the annular operation platform 126 is configured without installing a self-lifting operation platform, so that the welding operation requirement is met, and the use cost is reduced.

In yet another embodiment, the lifting mechanism 104 may be a hoist or other lifting mechanism such as a chain hoist; the legs 122 do not adopt a box-type beam structure, the middle of each 2 legs 122 is not connected by a cross beam 124, or the cross beam 124 adopts a box-type beam structure; the driving lifting (hydraulic or friction wheel walking) mode of the circular rail type steel pipe circular crane can be changed, or the circular rail type steel pipe circular crane can be cancelled; the annular work platform 126 may be replaced with an automated lift platform.
