Technical Field

[0001] The utility model relates to the technical field of LNG storage tanks, in particular to a right-angle flatness template. Background Art

[0002] In the process of energy structure transformation and upgrading, natural gas plays an indispensable role. As an important device for storing low-temperature liquefied natural gas, the safety, stability and durability of LNG storage tanks have always been the focus of people's attention. The existing LNG storage tanks are of various types and widely used, but there are still some problems in the construction of LNG storage tanks.

[0003] When constructing an LNG tank, the inner wall of the tank needs to be inspected for flatness before installing the corner insulation modules used in the enclosure system. The existing solution is the traditional steel ruler or similar tooling, which is small in size, low in efficiency, and inconvenient to measure. However, some large-scale measuring tools are large in overall size and occupy a large space. Therefore, it is necessary to improve the existing measuring tools. Utility Model Content

[0006] Preferably, an anti-slip groove is provided on the surface of the sleeve.

[0007] Preferably, a guide rail is fixedly installed inside the top plate, and a pressure block is slidably connected to the inner wall of the guide rail, and the back side of the pressure block is in contact with the surface of the wedge block.

[0008] Preferably, the surface of the top plate is provided with an opening for use with the pressing block.

[0009] Beneficial effects: The utility model provides a right-angle flatness template. Compared with the prior art, it has the following beneficial effects:

[0010] The right-angle flatness template is fixedly installed with a fixing rod through one side of the top of the bottom plate, and a round hole is opened on the surface of the fixing rod. The sleeve is fixedly connected to the fixing rod by screws. The other side of the top of the bottom plate is fixedly connected with a fixing plate. The top of the fixing plate passes through the top plate and extends to the inside of the top plate. A reset spring is fixedly installed behind the inner cavity of the fixing plate, and one end of the reset spring is fixedly connected with a wedge block. The surface of the wedge block passes through the fixing plate and the top plate in turn and extends to the inside of the top plate. The overall size is large, and the flatness of the inner wall of the LNG tank can be quickly inspected when it is constructed, which greatly improves the overall inspection efficiency and facilitates the operation of the staff. And when not in use, it can be disassembled for storage and placement, reducing the occupied space. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 5The utility model provides a technical solution: a right-angle flatness template, including a top plate 1 and a bottom plate 2, the top plate 1 is located directly above the bottom plate 2, a sleeve 3 is fixedly installed on one side of the bottom of the top plate 1, and a screw 4 is provided at the tail end of the sleeve 3, a fixing rod 5 is fixedly installed on one side of the top of the bottom plate 2, and a round hole 6 is opened on the surface of the fixing rod 5, the sleeve 3 and the fixing rod 5 are fixedly connected by screws 4, a fixing plate 7 is fixedly connected to the other side of the top of the bottom plate 2, the top of the fixing plate 7 passes through the top plate 1 and extends to the inside of the top plate 1, a return spring 8 is fixedly installed at the rear of the inner cavity of the fixing plate 7, and one end of the return spring 8 is fixedly connected to a wedge block 9, the surface of the wedge block 9 passes through the fixing plate 7 and the top plate 1 in sequence and extends to the inside of the top plate 1, and at the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0019] See also Figure 1-Figure 5 The surface of the sleeve 3 is provided with an anti-slip groove 10, a guide rail 11 is fixedly installed inside the top plate 1, and a pressure block 12 is slidably connected to the inner wall of the guide rail 11, the back of the pressure block 12 contacts the surface of the wedge block 9, and the surface of the top plate 1 is provided with an opening for use with the pressure block 12.

[0020] During use, when the measuring angle is greater than 90°, the tooling will be close to the right-angle area, and a gap will be generated between one longitudinal side and the surface. By measuring and drawing the unqualified area according to the required accuracy, it is convenient for subsequent repairs and lays a good foundation for subsequent work. When the measuring angle is less than 90°, there is a gap between the bottom of the tooling and the right-angle area. By measuring, the unqualified area is drawn and then repaired to meet the flatness requirements. The user can hold the sleeve 3 by hand during use to facilitate moving the whole to the appropriate position, and the anti-slip groove 10 can effectively prevent it from falling off. When the tooling is not in use, the user can first loosen the screw 4 so that the sleeve 3 and the fixing rod 5 are no longer fixed, and then squeeze the pressure block 12. After squeezing, the pressure block 12 will drive the movement of the wedge block 9. When the wedge block 9 has completely moved to the inside of the fixing plate 7, the user can pull the bottom plate 2 off the bottom of the top plate 1.
