Description

Technical Field

[0001] The utility model relates to the technical field of box-type substation processing, in particular to a flexible welding device for box-type substations. Background Technique

[0002] As a complete set of power equipment integrating high-voltage switch systems, distribution transformers and low-voltage distribution devices, box-type substations are one of the core equipment for urban power grid upgrading and the construction of intelligent power distribution systems. This equipment adopts modular design and fully enclosed structure, and has technical characteristics such as compact structure, reliable power supply and strong environmental adaptability.

[0003] In terms of structural manufacturing technology, box-type substations adopt a multi-level composite welding system. The basic framework is formed by three-dimensional welding of multiple groups of special-shaped steel components through a precision positioning tooling, and then 2.5-6mm cold-rolled steel plates are welded together on the periphery to form a composite protective shell. Since the box structure generally reaches a typical size of 5m×3m×2.5m, the total length of the welds can reach more than 120 linear meters, and welding operations in various spatial positions such as flat welding, vertical welding and overhead welding are involved, which pose strict requirements on process indicators such as weld penetration control, thermal deformation and fatigue strength. In the existing production methods, more than 80% of enterprises still use manual arc welding technology, which shows process limitations in three dimensions: firstly, for complex spatial welds, the operator needs to frequently adjust the body position, resulting in the effective welding time accounting for less than 40%; secondly, the molten pool temperature fluctuation range of manual welding reaches ±200°C, inducing grain coarsening of the microstructure and reducing the impact toughness of the weld by about 25%; thirdly, the interlayer quality control of multi-layer welding of thick plates depends on the welder's experience, and the rework rate remains at the level of 12%-15% all year round.

[0043] The present utility model will be further described in detail below in conjunction with the drawings.

[0044] As Figure 1 、 2As shown in the figure, the specific structure of the flexible welding equipment for box-type substations includes a frame 1. Emergency stop switches are provided at the four corners of the frame 1. When an emergency occurs, the operator can quickly trigger any emergency stop switch to achieve emergency shutdown of the equipment. The frame 1 is arranged on one side of the tooling base 7, and a box-type substation to be welded is arranged on the tooling base 7. The moving component 2 is arranged at the lower end of the frame 1 in a liftable manner. When the moving component 2 moves downward, the moving component 2 can support the frame 1 and realize the movement of the frame 1. The robot 4 is connected to the frame 1 through the translation component 3. In a specific implementation, the translation component 3 adopts an electric linear slide. The translation component 3 can drive the robot 4 to move linearly, thereby changing the position of the robot 4 on the frame 1. The welding torch 5 is arranged at the execution end of the robot 4. The welding torch 5 and the robot 4 are connected by a quick-release connection, which is convenient for quickly replacing the welding torch 5. The robot 4 drives the welding torch 5 to weld the box-type substation on the tooling base 7. Control devices such as a hydraulic station and a control cabinet are also arranged on the frame 1.

[0045] A number of positioning components 6 are arranged on one side of the frame 1, and the frame 1 is connected to the tooling base 7 through the positioning components 6.

[0046] As Figure 3 、 5 shown, the tooling base 7 is provided with a number of positioning holes 71. The positioning component 6 includes a bracket 61, and the bracket 61 is fixedly connected to the frame 1. A plug pin 63 is arranged at the lower end of the bracket 61, and the plug pin 63 is inserted into the positioning hole 71. Thus, a reliable connection is formed between the frame 1 and the tooling base 7. The positioning component 6 further includes a cylinder 62, and the cylinder 62 is arranged at the upper end of the bracket 61. A mandrel 65 is arranged in the bracket 61 in a longitudinally slidable manner, and the mandrel 65 is driven by the cylinder 62. An inclined contact surface is provided on the side wall of the lower end of the mandrel 65. A slider 64 is arranged in the plug pin 63 in a horizontally slidable manner, and the inner end of the slider 64 is slidably connected to the inclined contact surface of the mandrel 65. The longitudinal movement of the mandrel 65 can drive the slider 64 to perform horizontal translation. When the mandrel 65 moves downward, the outer end of the slider 64 can extend out of the plug pin 63 and abut against the inner wall of the positioning hole 71. Thus, the connection rigidity between the positioning component 6 and the positioning hole 71 is strengthened.

[0047] Based on the above technical solutions, the configured high-precision positioning component 6 forms a stable and reliable rigid connection with the tooling base 7 through a modular connection mechanism, effectively ensuring the positioning accuracy of the welding reference and the overall stability of the system.

[0048] As Figure 4As shown in the figure, there are four moving components 2, which are respectively arranged at the four corners of the frame 1. The moving component 2 includes a lifting frame 22, which is longitudinally slidably arranged in the frame 1. The lifting frame 22 is slidably connected to the frame 1 through a guide rail slider. An oil cylinder 21 is arranged on the frame 1, and the lifting frame 22 is connected to the telescopic end of the oil cylinder 21. The oil cylinder 21 is used to drive the lifting frame 22 to lift. A moving wheel 23 is rotatably arranged at the lower end of the lifting frame 22. The moving wheel 23 is a Mecanum wheel driven by a servo motor. The frame 1 can be driven to move horizontally in any direction by the four Mecanum wheels.

[0049] Based on the above technical solutions, the configured moving components enable it to have a moving function, enabling the welding equipment to flexibly adjust its spatial position according to production requirements and adapt to the welding positioning requirements of various box-type substations with different specifications and types.
