It is well known that chemical containers are the general term of pressed devices in the fields of chemical engineering and petrochemical engineering. Frequently-used reaction containers include a reaction kettle, a tower and a heat exchanger, etc., and an overwhelming majority of productive processes in the chemical industry are implemented in chemical devices. Among these devices, some are used for storing materials, and some are utilized to implement the physical process. Though these devices are different in sizes and shape structures and more diversified in internal structures, these devices all have a casing, and this casing is referred to a container. The container is generally composed of a barrel, a seal head and other parts (such as a flange, a support, a connecting pipe, a manhole, a hand hole, a sight glass and a liquidometer). There are various classification methods according to different applications, construction materials, manufacturing methods, shapes, stress conditions, assembly modes, installation positions and container wall thicknesses. The key classification methods are as follows: according to the shapes, the containers can be divided into cylindrical containers, spherical containers and rectangular containers; according to pressure-bearing conditions, the containers can be divided into containers bearing internal pressure and containers bearing external pressure; according to the container wall thicknesses, the containers can be divided into thin-wall containers and thick-wall containers; and according to the materials, the containers can be divided into steel containers, cast iron containers, aluminum containers, graphite containers, plastic containers, etc.

At present, these chemical containers inevitably need to be hoisted and overturned in the machining process, where the two ends of a barrel structure of a container need to turn around and be overturned in the machining process. In the process of turning around and overturning, since no appropriate clamp is available, spot welding of temporary lifting lugs needs to be performed on the outer wall of the barrel; as a result, it wastes time and labor and easily lead to the damage to surface of a barrel plate. Cr-Mo steel and the like need to be preheated before being welded, and magnetic particle testing further needs to be carried out when the temporary lifting lugs are eliminated, so that the complex working process increases workers’ labor intensity and also reduces working efficiency.
