Description

Technical Field

[0001] The utility model relates to the technical field of preparation of a low-temperature liquid tank container, in particular to a sealing head welding lining plate fixing device. Background Art

[0002] Because the internal medium of cryogenic liquid tank containers is a deep cold medium, the outer layer needs to adopt an insulation structure. At present, most of the structures used in the market are high vacuum multi-layer insulation containers. Due to structural factors and size limitations, it is not easy to set a manhole on the tank container, so welders cannot enter the container to weld the end seam. At present, most of the market adopts the method of welding by adding a liner inside the end seam, that is, adding a 40mm wide liner inside the annular seam of the tank container head and the tank container cylinder. This welding structure allows personnel to weld outside the tank container and ensure the quality of the weld. In the prior art, there is no clamping tool dedicated to the welding of the head liner. Summary of the invention

[0003] The technical problem to be solved by the utility model is to propose a device for fixing a sealing head welding lining plate which is easy to use and improves welding quality in view of the deficiencies of the prior art.

[0004] The technical problem to be solved by the utility model is achieved through the following technical solutions, a device for fixing a head welding liner, which is characterized by:

[0005] It includes an external positioning mechanism that cooperates with the outer cylindrical surface of the tank head and a pressing mechanism that presses the inner welded liner against the inner surface of the tank head.

[0006] There is a support plate positioned with the end face of the tank container head.

[0007] The external positioning mechanism is provided with two fixed shafts fixed on the support plate, the two fixed shafts are parallel and the support plate is vertically arranged, and rollers are installed on the fixed shafts.

[0008] The clamping mechanism is provided with a rotating shaft mounted on the supporting plate. The rotating shaft is arranged at the middle position between the two fixed shafts and is arranged equal to the fixed shafts. A clamping cam is arranged on the rotating shaft.

[0009] The technical problem to be solved by the utility model can be further achieved through the following technical solution: a driving handle is arranged outside the rotating shaft.

[0010] The technical problem to be solved by the utility model can be further achieved through the following technical solution: the surface of the roller is covered with a buffer cover.

[0011] The technical problem to be solved by the utility model can also be further achieved through the following technical solution: a supporting upright plate is fixed outwardly to the supporting plate, and the supporting upright plate is perpendicular to the supporting plate and is arranged between the fixed axis and the rotating axis.

[0012] The technical problem to be solved by the present invention can be further achieved through the following technical solution: reinforcing rib plates are arranged between the two sides of the supporting vertical plate and the supporting plate.

[0013] Compared with the prior art, the utility model has a simple and practical overall structure through roller positioning and cam pressing, and can realize the assembly and installation of multiple specifications of tank head welding liner plates. It is easy to use, the assembly tolerance is guaranteed, and the welding quality is greatly improved. The device not only greatly improves the assembly work efficiency, but also saves a certain amount of cost for tank manufacturing. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The specific technical solutions of the present invention are further described below. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer and to facilitate those skilled in the art to further understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them, and do not constitute a limitation on the rights thereof. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0018] A device for fixing a head welding liner,

[0019] It includes an external positioning mechanism that cooperates with the outer cylindrical surface of the tank head 9 and a pressing mechanism that presses the inner welded liner 10 against the inner surface of the tank head.

[0020] A support plate 2 is provided for positioning with the end face of the tank container head. The external positioning mechanism is provided with two fixed shafts 1 fixed on the support plate. The two fixed shafts are parallel and the support plate is vertically arranged. Rollers 8 are installed on the fixed shafts.

[0021] The clamping mechanism is provided with a rotating shaft 5 mounted on the supporting plate. The rotating shaft is arranged at the middle position between the two fixed shafts and is arranged equal to the fixed shafts. A clamping cam 11 is arranged on the rotating shaft.

[0022] A driving handle 6 is arranged outside the rotating shaft.

[0023] The roller surface is covered with a buffer cover 7.

[0024] A support 4 is fixed outwardly of the support plate, and the support vertical plate is perpendicular to the support plate and is arranged between the fixed axis and the rotating axis.

[0025] Reinforcing rib plates 3 are arranged between the two sides of the supporting upright plate and the supporting plate.

[0026] This device uses a rotating cam to press, and then combines two fixed rollers and a buffer cover for positioning. The tank head and the welding liner are tightly fitted by rotating the cam, and then spot welding is performed manually. The above steps are repeated by rotating the head several times, so that the welding liner can be quickly fitted inside the edge of the tank head, preparing for the assembly welding of the tank head and the tank cylinder.
