Description

Technical Field

[0001] The utility model belongs to the technical field of mating tools, and in particular relates to a special tool for mating annular joints on the wall of a large storage tank. Background Art

[0002] The wall of a large storage tank is made of several layers of wall panels that are welded together. The welding process requires the use of welding tools, and the ease of use of the welding tools directly affects the efficiency and quality of the wall panel welding.

[0003] When installing the tank wall, the traditional method of welding angle steel blocks, wedges and hammers is often used. For example, when two wall panels are connected, the angle steel blocks are welded first, the wedges are inserted into the blocks and the wedges are hit with hammers to complete the connection. However, the connection efficiency is not high, which can easily cause damage to the local part of the tank wall. After the connection is completed, it is necessary to cut off the angle steel blocks, grind the welds (if the parent material is damaged, re-welding is required), and perform penetration inspection, which is a tedious workload, and there are certain installation quality risks.

[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The embodiments described in this application are only embodiments of a part of the utility model, not all embodiments. Based on the spirit of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the utility model.

[0017] In the description of the present application, it needs to be explained that the orientation or position relationship indicated by terms such as "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "between", etc. is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present application and simplifying the description.

[0018] like Figure 1-2 As shown, a special tool for aligning a large storage tank wall annular joint includes a backing plate 1 and a limiting steel plate, wherein the limiting steel plate includes a first limiting steel plate 2 and a second limiting steel plate 3. The backing plate 1 is provided with a first opening 5 and a second opening 6 near both ends. The first limiting steel plate 2 is welded in the first opening 5 near one end of the backing plate 1, and the second limiting steel plate 3 is installed in the second opening 6 near the other end of the backing plate 1.

[0019] The special matching tool is installed at the matching position of the upper and lower wall panels of the large storage tank. The wall panel is arranged at the center of the pad 1, and the first limiting steel plate 2 and the second limiting steel plate 3 are located on both sides of the wall panel.

[0020] The special tool for matching further includes an adjustment plate 4, and there are two adjustment plates 4, one of which is installed in the gap between the first opening 5 and the center of the backing plate 1, and the other is installed in the gap between the second opening 6 and the center of the backing plate 1, and the adjustment plates 4 are closely attached to the upper and lower wall surfaces of the large storage tank. The arrangement of the adjustment plates 4 enables the special matching device to be applicable to large storage tank walls of different thicknesses, thereby improving the applicability of the device.

[0021] The first limiting steel plate 2 is a rectangular steel plate, and the second limiting steel plate 3 is a right-angled triangular steel plate, the width of which decreases from top to bottom, and the right-angle end is connected to the adjustment plate 4.
