Description

Technical Field

[0001] This utility model relates to the technical field of large arc plate docking tools, and in particular to a device for assisting in the straight edge splicing of large steel arc plates. Background Technology

[0002] In nuclear power engineering, petrochemical and other technical fields, cylindrical large-capacity tanks and large-diameter pipes are standard components. Due to their large size, these components require the assembly of several large or super-large curved plates during installation or fabrication. Especially in the welding and fabrication of tanks with a volume exceeding 10,000 cubic meters, the large size and weight of the curved plates, coupled with severe localized stress during hoisting, easily leads to varying degrees of deformation, making it difficult to naturally align the straight edges of the two plates to be joined. Traditionally, this is addressed by manually moving and adjusting the plates using tools such as chain hoists. However, sometimes the curved plates deform significantly, causing severe warping of the straight edges. Manual adjustment is difficult, slow, and inaccurate, making it challenging to quickly and smoothly align the straight edges of the curved plates, severely impacting project progress.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0020] An auxiliary device for splicing large steel arc plates is used for welding the two straight edges of the large steel arc plate 1. At least two of these auxiliary devices should be used together. When the width of the large steel arc plate 1 is large, the number of auxiliary devices can be increased appropriately.

[0021] like Figures 1 to 4 As shown, the auxiliary device for splicing large steel arc plates includes an auxiliary support plate 2, which assembles the various components together to form a complete structure, facilitating one-time transfer and assembly with the large steel arc plate 1. The auxiliary support plate 2 is provided with at least two auxiliary support legs 3, which are used to install and fix the entire auxiliary device on the surfaces of the two large steel arc plates 1 to be welded.

[0022] Specifically, the auxiliary support plate 2 is configured as an arc-shaped steel plate, with the arc of the auxiliary support plate 2 protruding downwards. The auxiliary support plate 2 is formed by a plate rolling process and is designed with a certain curvature to provide reverse support force to offset the stress generated during assembly and use with the large steel arc plate 1. Each of the auxiliary support legs 3 is fixed to the arc-shaped sidewall of the auxiliary support plate 2, and at least two auxiliary support legs 3 are provided on each sidewall of the auxiliary support leg 3, that is, the entire device is provided with at least four auxiliary support legs 3 to ensure the stability of the device during the splicing and use of the large steel arc plate 1. The auxiliary support legs 3 on the same sidewall of the auxiliary support plate 2 are symmetrically arranged to ensure that the force is evenly distributed when supporting the auxiliary support plate 2. In use, the auxiliary support plate 2 spans the weld seam of the two arc plates, and the auxiliary support legs 3 are spot welded to the corresponding large steel arc plate 1.

[0023] A support adjustment hole 4 is arranged through the auxiliary support plate 2, and the support adjustment hole 4 is symmetrically arranged on the auxiliary support plate 2. At least two of the symmetrically arranged support adjustment holes 4 are internally threaded with an arc plate tightening device. By operating the arc plate tightening device, the large steel arc plate 1 to be welded can be pushed outward to achieve smooth alignment of the straight edges of the two large steel arc plates 1, thereby facilitating high-quality welding.

[0024] The arc plate clamping device includes a clamping screw 5 that passes through the support adjustment hole 4. A clamping pressure plate 6 is fixedly connected to the end of the clamping screw 5, and the clamping pressure plate 6 and the auxiliary support leg 3 are located on the same side of the auxiliary support plate 2. By adjusting the length of the clamping screw 5 passing through the auxiliary support plate 2, the clamping pressure plate 6 can be brought into contact with the surface of the corresponding large steel arc plate 1. Continuous rotation and adjustment can push the end of the large steel arc plate 1 outwards until it aligns with the end of another large steel arc plate 1. Multiple support adjustment holes 4 are provided, and additional clamping screws 5 can be added depending on the degree of adjustment required for the large steel arc plate 1, thereby increasing the adjustment strength and ensuring the adjustment effect.

[0025] The other end of the tightening screw 5 is detachably equipped with an easy-to-use operating handwheel 7. This detachable configuration facilitates the assembly and disassembly of the tightening screw 5 and the auxiliary support plate 2, allowing for adjustments to the number of tightening screws 5 as needed. An anti-slip pad 8 is fixed to the outer surface of the tightening pressure plate 6. This anti-slip pad 8 can be a rubber pad to prevent slippage, ensuring effective and efficient adjustment of the large steel arc plate 1. Tightening nuts 9 are welded to the surface of the auxiliary support plate 2 corresponding to each of the support adjustment holes 4, improving the stability of the assembly between the auxiliary support plate 2 and the tightening screw 5.

[0026] like Figure 4 As shown, during use, the two large steel arc plates 1 to be welded are erected using lifting equipment in conjunction with the lifting lugs 10 pre-spot-welded to the surface of the large steel arc plate 1. They are then fixed using the limiting base 11 and other supporting structures, ensuring the straight edges of the two large steel arc plates 1 to be welded are close together. These operations are standard procedures for those skilled in the art and will not be described in detail here. At least two sets of auxiliary devices are used. Each auxiliary support plate 2 is positioned across the weld seam of the two large steel arc plates 1, and each auxiliary support leg 3 is spot-welded to the corresponding surface of the large steel arc plate 1. The operating handwheel 7 is rotated until the top clamping plate 6 and the anti-slip pad 8 are in contact with the surface of the large steel arc plate 1. Continuing to rotate the operating handwheel 7 allows the ends of the two large steel arc plates 1 to be aligned and precisely abutted under the external pressure of the top clamping plate 6 and the anti-slip pad 8, enabling welding.

[0027] This embodiment has the following advantages:

[0028] 1. The auxiliary support plate 2 is designed with an arc shape to enhance its supporting force and effectively resist the bending stress of the steel plate itself.

[0029] 2. The overall structure is simple, easy to manufacture and install, which can greatly reduce construction difficulty and time.

[0030] 3. By rotating the tightening screw 5, the ends of the large steel arc plate 1 can be finely adjusted and corrected with the help of the tightening screw 5 and the tightening pressure plate 6, which can ensure the accuracy of the butt joint of the large steel arc plate 1, thereby improving the weld strength and quality.

[0031] 4. The multiple auxiliary support legs 3 provide stable support, avoiding displacement and deviation during the splicing process.

[0032] 5. Wide applicability: It can be used for splicing large steel arc plates of different thicknesses and sizes, and has a wide range of application prospects.

[0033] Example of use 1:

[0034] In the installation of a 10,000 cubic meter water tank, this device is used to splice a large steel arc plate 1 with a thickness of 20 mm. Due to the arc design of the auxiliary support plate 2, the necessary support force is provided. The high-precision splicing and adjustment is achieved through the tightening screw 5, and the operation time is reduced by at least 30% compared with the traditional method.

[0035] Example of use 2:

[0036] During the installation of a steel cylinder with a thickness of 25 mm and a diameter of 5 meters, the welding effect was improved by 20% compared with the traditional method, and the docking time was shortened by about 40%.

[0037] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
