Description

Technical Field

[0001] The utility model relates to the technical field of gas storage tanks, in particular to an end forming device for a gas storage tank body which is convenient to fix. Background Technique

[0002] A gas storage tank refers to a device specifically used to store gas, and at the same time plays a role in stabilizing the system pressure. It generally consists of a cylinder body and end heads at both ends. The end forming of the gas storage tank is to weld the end heads on both sides of the cylinder body to form the final tank body. During the welding process, it is necessary to stably fit the end heads on both ends of the cylinder body to avoid displacement and misalignment during the welding process. At the same time, since the end of the cylinder body is a circular structure, in order to improve production efficiency during welding, it is necessary to control the rotation of the cylinder body and the end heads to achieve circular welding, which requires a stable fixing device.

[0003] At present, the Chinese patent with the application number CN201920026741.5 discloses a gas storage tank end head welding device, which includes a bracket, a first welding head and a second welding head. The top of the bracket is fixedly connected with a horizontally arranged top plate. One inner wall of the bracket is fixedly connected with a bearing seat, and a connecting rod is rotatably connected in the bearing seat. One end of the connecting rod is fixedly connected with a first clamp. A second clamp is arranged on the other inner wall of the bracket. One end of the connecting rod fixedly connected with the second clamp is fixedly connected with one end of the piston rod of the second telescopic cylinder. One end of the second telescopic cylinder is fixedly connected with a connecting shaft through a connecting plate. The connecting shaft is rotatably connected with a rotating motor with a self - contained motor shaft. The bottom of the top plate is symmetrically provided with placement boxes, and each placement box is provided with a welding device. Each welding device is respectively connected with a first welding head and a second welding head, and the first welding head and the second welding head penetrate through the bottom plate of the placement box. This device can perform synchronous welding on both ends of the cylinder body to improve efficiency. However, during welding, the contact area between the fixing part and the end head is small, and only the cylinder body and the two end heads on both sides are driven to rotate by a motor on one side, so the fixing property is poor and there is a risk of misalignment.

[0004] Based on this, the utility model designs an end forming device for a gas storage tank body which is convenient to fix to solve the above problems. Content of the Utility Model

[0011] Furthermore, the horizontal plane where the top of the support rotating rod is located is higher than the horizontal plane where the top of the side plate is located. The bottom end of the support rotating rod contacts the bottom end of the support bar.

[0012] Furthermore, the first chutes are symmetrically arranged on both sides of the center of the bottom plate and one end penetrates through the side surface of the bottom plate.
