Description

Technical Field

[0001] The utility model belongs to the technical field of nuclear power plant construction, and in particular relates to a welding tool for a nuclear power plant CA structure module. Background Art

[0002] The modules of the AP1000 nuclear power plant can be roughly divided into two categories, structural modules and equipment modules. The structural modules are divided into CA, CB, CH and CS, and the CA structural modules are divided into box-type and single-plate types. During the construction of the nuclear power plant, a large number of CA structural module permanent accessories are installed, among which the foundation connection plate is located at the bottom of the structural module, and plays an important role in supporting and fixing the structural module. However, due to the large size and heavy weight of the foundation connection plate, its traditional installation method is to use hydraulic jacks as support to adjust the foundation connection plate and the structural module to form a team, or to use the form of setting up a platform at the structural module to weld steel columns to support the installation of the foundation connection plate. However, these two installation methods have long construction periods, low efficiency and high costs. Utility Model Content

[0032] Example:

[0033] This embodiment provides a tool for welding a nuclear power plant CA structure module, which is used to solve the technical problem of low efficiency of tooling for welding a nuclear power plant CA structure module in the prior art. The tool for welding a nuclear power plant CA structure module includes a support frame 3 and an adjustment component 4, wherein:

[0034] One end of the support frame 3 is installed on the module wall 1, and the support frame 3 has a accommodating cavity, which is used to place the basic connecting plate 2. In this way, by installing the support frame 3 on the module wall 1, the structure of the nuclear power plant CA structure module welding tooling provided by the embodiment of the utility model is more compact and the space utilization rate is higher. In addition, placing the basic connecting plate 2 through the support frame 3 is more stable and saves manpower.

[0035] The adjusting component 4 is installed on the supporting frame 3, and the adjusting component 4 is used to adjust the height and levelness of the foundation connecting plate 2 so as to make the top wall of the foundation connecting plate 2 fit closely with the bottom wall of the module wall 1. In this way, through the setting of the adjusting component 4, it is easier to move the foundation connecting plate 2 upward, and at the same time adjust the levelness of the foundation connecting plate 2 to ensure that the top wall of the foundation connecting plate 2 is completely fitted with the bottom wall of the module wall 1, thereby reducing the difficulty of welding the foundation connecting plate 2 and the module wall 1.

[0036] With the above structure, when welding the nuclear power plant CA structure module, first install one end of the support frame 3 on the module wall 1, and then place the base connecting plate 2 in the receiving cavity of the support frame 3. In this way, through the setting of the support frame 3 fixedly connected to the module wall 1, the structure is made more compact. Then drive the adjusting assembly 4 to move the base connecting plate 2 upward until the top wall of the base connecting plate 2 is completely attached to the bottom wall of the module wall 1. Finally, weld the base connecting plate 2 and the module wall 1. In this way, through the setting of the adjusting assembly 4, it is more convenient to move the base connecting plate 2 and more convenient to adjust the levelness of the base connecting plate 2 to make it completely attached to the bottom wall of the module wall 1, thus facilitating welding. Therefore, through the setting of the support frame 3 and the adjusting assembly 4, the tool for welding the nuclear power plant CA structure module provided by the present utility model is more convenient to use, thereby improving the welding efficiency.

[0037] An optional implementation manner of this embodiment is as follows: The support frame 3 includes a first connection block 31, a second connection block 32, and a mounting block 33, where:

[0038] One end of the first connection block 31 is installed on the side wall of the module wall 1 and is horizontally arranged.

[0039] One end of the second connection block 32 is installed at the other end of the first connection block 31 and is perpendicularly arranged with the first connection block 31, that is, the second connection block 32 is vertically arranged.

[0040] One end of the mounting block 33 is installed at the other end of the second connection block 32 and is perpendicularly arranged with the second connection block 32. The other end of the mounting block 33 extends towards the direction close to the module wall 1, that is, the mounting block 33 is parallel to the first connection block 31. The first connection block 31, the second connection block 32, and the mounting block 33 enclose a "C"-shaped structural member. It should be noted that the first connection block 31, the second connection block 32, and the mounting block 33 can be connected together by welding, bonding, or heat melting. Of course, they can also be integrally formed.

[0041] Optionally, the first connection block 31, the second connection block 32, and the mounting block 33 are all structural members made of steel. Steel has high strength, good plasticity, and toughness.

[0042] An optional implementation manner of this embodiment is as follows: The length of the first connection block 31 is greater than half of the length of the base connecting plate 2, and the length of the mounting block 33 is greater than the sum of the length of the first connection block 31 and the thickness of the module wall 1. In this way, the base connecting plate 2 can be stably placed in the receiving cavity.

[0043] An optional implementation of this embodiment is as follows: the distance between the bottom wall of the first connecting block 31 and the top wall of the mounting block 33 is greater than the thickness of the basic connecting plate 2, so that it is easier to place the basic connecting plate 2 into the accommodating cavity.

[0044] An optional implementation of this embodiment is as follows: the adjustment assembly 4 includes at least two nuts 41 and at least two screw rods 42, wherein:

[0045] At least two nuts 41 are respectively mounted on two opposite sides of the mounting block 33 and are located in the length direction of the mounting block 33 .

[0046] At least two screws 42 are respectively screwed into at least two nuts 41. In this way, through the setting of the nuts 41 and the screws 42, after the basic connecting plate 2 is placed in the accommodating cavity, multiple screws 42 are rotated at the same time, and the length of the screws 42 extending out of the nuts 41 is adjusted, so that the screws 42 push the basic connecting plate 2 upward until the top wall of the basic connecting plate 2 is completely fitted with the bottom wall of the module wall 1, and the rotation of the screws 42 is stopped.

[0047] Optionally, the number of nuts 41 is four, and the four nuts 41 are evenly installed on the opposite sides of the mounting block 33. In this way, through the arrangement of the four nuts 41, when one of the nuts 41 is damaged, there is still a spare nut 41 and it can continue to be used normally.

[0048] Optionally, the four nuts 41 are located on four vertices of the same rectangle.

[0049] Optionally, there are four screw rods 42, which are respectively screwed into four nuts 41. Thus, by providing the four screw rods 42, the force on the base connecting plate 2 is more even, thereby enabling the base connecting plate 2 to move upward more smoothly.

[0050] An optional implementation of this embodiment is as follows: it also includes a handle 43, and the number of the handles 43 is four. The four handles 43 are respectively installed at the bottom ends of the four nuts 41. In this way, through the setting of the handle 43, it is easier for the staff to rotate the screw 42, and then it is easier to adjust the length of the screw 42 extending out of the nut 41.

[0051] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
