Abstract
Description
Technical Field
[0001] This utility model relates to the field of closed-loop steel plate welding technology, specifically to a steel cover-type air cushion pressure regulating chamber steel plate welding support structure. Background Technology
[0002] Air-tight steel plates are structural materials used in steel-shrouded air-cushion pressure regulating chambers, typically made of special high-strength alloy steel. They possess high strength and corrosion resistance, can withstand high-pressure and high-temperature environments, and effectively prevent air leakage, thus ensuring the safe operation of the pressure regulating chamber. During the welding process of steel-shrouded air-cushion pressure regulating chambers, the air-tight steel plates are usually joined using welding techniques.
[0003] In the welding process of pressure-controlled steel plates, support is a crucial step. The purpose of support is to fix and support the steel plate, ensuring stability and accuracy during welding, and preventing deformation or displacement. Unstable or improper support clamping can lead to defects in the weld joint, such as incomplete fusion, porosity, and cracks, thus affecting weld quality. This can cause changes in structural dimensions and shape, impacting the structural safety and stability of the pressure regulating chamber.
[0004] The airtight steel plate plays an important role in the steel-covered air cushion pressure regulating chamber. Therefore, we propose a welded support structure for the steel plate of the steel-covered air cushion pressure regulating chamber. Appropriate processes and methods are required to ensure welding quality and structural safety. Utility Model Content
[0005] The purpose of this utility model is to provide a steel-plate welded support structure for a steel-covered air-cushion pressure regulating chamber, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel-shrouded air-cushion pressure regulating chamber steel plate welded support structure, including two concave plates arranged symmetrically. Air-sealing steel plates are symmetrically arranged at the bottom of the inner sidewall of each concave plate, and the inner sidewalls of the two air-sealing steel plates are in contact with each other. A first hydraulic cylinder is symmetrically fixedly connected to the top of the inner sidewall of each concave plate. A pressure plate is fixedly connected to the lower surface of the first hydraulic cylinder. The inner wall of the pressure plate is sleeved with the sidewall of the concave plate, and the fit is clearance-fitted. The lower surface of the pressure plate is in contact with the upper surface of the air-sealing steel plate.
[0007] Preferably, it also includes a support structure, the top of which is fixedly connected to the bottom of the concave plate.
[0008] Preferably, the support structure includes a second hydraulic cylinder, the upper surface of which is fixedly connected with a convex block, the upper surface of which engages with the lower surface of the concave plate, and bolts are fitted onto the lower surface of the convex block, the top of which is threadedly connected to the lower surface of the concave plate.
[0009] Preferably, a base is fixedly connected to the lower surface of the second hydraulic cylinder, and a circular hole is formed on the surface of the base.
[0010] Preferably, the inner cavity of the pressure plate is provided with an electromagnet, and the lower surface of the electromagnet is attracted to the upper surface of the airtight steel plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When welding the airtight steel plate, the airtight steel plates on both sides can be clamped and supported. At the same time, an opening is provided to leave space for welding. Meanwhile, the clamping support around the opening can ensure the safety of the space. The setting of the electromagnet can effectively strengthen the stability of the support and make the operation safer. By adjusting the clamping support on both sides of the airtight steel plate and the bottom support structure, it can be ensured that the steel plates on both sides are on the same horizontal line. At the same time, the height can be raised and lowered, which not only provides a convenient lifting function, but also the hydraulic cylinder has sufficient supporting force to ensure the stability of the steel plate support. In addition, the support structure also has a disassembly function, and different specifications of hydraulic cylinders can be selected according to the actual construction environment to flexibly adapt to various construction environments.
