Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, and in particular relates to a modular multifunctional welding vehicle. Background Art

[0002] Welding started with carbon arc welding at the end of the 19th century and has developed into a pillar technology for industrial manufacturing over the past century. The welding car is an important piece of equipment in the manufacturing process of steel equipment. Compared with traditional manual welding, it has the advantages of good operating flexibility, controllable labor costs, high efficiency, good forming quality and low labor intensity.

[0003] At present, most welding vehicles on the market are designed only for welding tasks under specific conditions, with single functions and lack of integration. In the actual delivery and use of welded components, welding operations usually need to go through a series of processes such as welding, grinding, and dust removal. These processes are often completed separately by different equipment, which not only leads to low operating efficiency, but also easily produces a large amount of dust pollution, while increasing labor costs and management difficulties. In addition, with the increasingly stringent environmental protection requirements, dust control and environmental friendliness during welding operations have also become urgent issues to be solved. Therefore, the development of an intelligent welding device that integrates multiple functions such as welding, grinding, and dust removal has important practical significance and application value. This integrated equipment can not only significantly improve welding efficiency and reduce labor costs, but also effectively reduce dust pollution, meeting the needs of modern industrial production for high efficiency, environmental protection, and intelligence. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and to design a modular multifunctional welding vehicle.

The specific connection method and control sequence should refer to the following working principle, and the electrical components are connected in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control part.

[0042] This technical solution is mainly aimed at the welding and grinding of butt joints, corner joints and lap joints in single-layer and multi-layer welding situations in plane, circumferential and longitudinal directions of cylinder sections. Due to its modular foundation, it can carry multiple welding guns and grinding heads at the same time.

[0043] First, connect the welding gun to an external welding machine and turn on the external power supply. The staff can control the brushless DC motor and grinding head through the control system, thereby controlling the welding and grinding speed of the device body.

[0044] When welding and grinding are required on butt joints, corner joints and lap joints in single-layer and multi-layer welding occasions on planes, circumferential and longitudinal directions of cylinder sections, the staff needs to use the magnetic track characteristics to adsorb the walking mechanism on the work platform, adjust the height adjuster according to the position difference of the work platform, and install the corresponding number of parallel slides and vertical slides at the same time, adjust the position relationship between the welding gun and the grinding head and the work platform in conjunction with the clamping slides and tighten the bolts, make fine adjustments by adjusting the clamping mechanism and the position of the welded part, align the rotatable clamp with the fastening clamp, tighten the butterfly nut to fix the welding gun and the grinding head, adjust the position relationship between the welding gun and the grinding head, and place the dust hood directly above the welding gun and grinding head. At this time, welding, grinding and dust collection can be carried out, and the staff adjusts the speed of the brushless DC motor through the control device to achieve control of the walking speed of the device and meet the welding and grinding speed requirements.

[0045] When remelting work is required, the staff needs to select the corresponding remelting device and install it on the clamping mechanism according to the use requirements. The corresponding number of parallel slide rails and vertical slide rails can be installed according to the remelting requirements to complete the corresponding remelting operation.

[0046] When steel beveling operations are required, the staff can select the corresponding flame cutting device according to the usage requirements, confirm the cutting angle, and adjust the angle and position of the multi-arm mechanism and the clamping mechanism to perform the beveling operation.

[0047] The above describes the basic principles, main features and usage scenarios of the present invention. Those skilled in the art should understand that the present invention is not limited by the above cases, and the above cases and descriptions are only for explaining the principles and usage scenarios of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
