Description

Technical Field

[0001] The invention relates to the technical field of steel material processing equipment, in particular to a steel structure processing and welding device with a convenient feeding mechanism. Background Art

[0002] In the process of steel structure processing, welding is a key step to ensure the stability and safety of the structure. Traditional welding equipment often faces the problems of difficult loading and low efficiency, especially when processing defective steel pipes, manual position adjustment and welding are required, which not only reduces production efficiency, but also increases labor intensity and cost.

[0003] In many cases, welding defects may occur in steel pipes during the production process, such as leaking welds, insufficient welding, etc., which require repair welding. However, the repair welding process usually requires manual operation, which is not only time-consuming, but also difficult to ensure the quality of repair welding due to the uncertainty of human factors. In addition, manual operation also increases the safety risks of workers.

[0004] In order to improve production efficiency and welding quality and reduce manual participation, some automated welding equipment has been developed. However, these devices often only focus on the automation of the welding process itself, ignoring the automation of the feeding process, resulting in the entire welding process still requiring manual assistance. Moreover, these devices can often only weld steel pipes at a single position during the welding process, and cannot achieve all-round welding. Summary of the invention

The first bevel gear and the second bevel gear are meshed with each other. The bottom of the second bevel gear is fixedly connected to a sleeve, and the bottom of the sleeve is rotatably connected to the upper surface of the mounting frame.

[0010] The outer side of the mounting frame is fixedly connected to a connecting frame by bolts, a driving block is arranged on the inner side of the top of the connecting frame, the driving block is connected to the outer surface of the threaded rod by threads, the two ends of the driving block are symmetrically rotatably connected to driving rods by connecting rods, the driving rods are arranged in an L shape, and the driving rods are rotatably connected to the inner surfaces on both sides of the bottom of the connecting frame.

[0011] The bottom of the driving rod is rotatably connected with a clamping block, and the clamping block is set as a special-shaped block. The inner side of the clamping block is set as an arc. The equipment can be installed by connecting the top of the mounting table with the electric push rod on the production line. After the installation is completed, the electric push rod on the production line is used to push the equipment as a whole to move downward. When the equipment moves above the defective steel pipe with leaking welding, the first motor and the second motor are started. After the first motor is started, it will drive the rotating shaft to rotate. The rotation of the rotating shaft on both sides of the first motor can drive the first bevel gear to rotate, and then the threaded rod is driven to rotate through the second bevel gear. As the threaded rod rotates, the driving block will be prompted to move downward in the connecting frame, thereby pushing the driving rod to rotate. As the driving rod rotates, the two clamping blocks can be moved to both sides. At this time, the device is then driven to move downward so that the two clamping blocks are on both sides of the defective steel pipe.

[0012] Preferably, a slide groove is provided on the inner surface of the clamping block, a buffer block is slidably connected in the slide groove, the buffer block is arranged in an arc shape, a plug board is fixedly connected to a side surface of the buffer block close to the clamping block, and the plug board is arranged as a nearly U-shaped plate.

[0013] Preferably, an elastic plate is fixedly connected inside the plug-in plate, the elastic plate is configured as a corrugated plate, an end of the elastic plate away from the buffer block is fixedly connected to an extrusion plate, and the extrusion plate is fixedly plugged inside the clamping block.

[0014] Preferably, the buffer block is rotatably connected to a rotating roller, and a rotating rod is fixedly connected to the inside of the rotating roller.

When the clamping block starts to clamp the defective steel pipe, the buffer block will first come into contact with the outer surface of the steel pipe, and as the clamping blocks approach each other, the The contact pressure between the buffer block and the outer surface of the steel pipe increases, thereby squeezing the buffer block. When the squeezing force on the buffer block increases, the squeezing force on the elastic plate between the plug-in plate and the squeezing plate will increase, thereby elastically squeezing and fixing the steel pipe through the elastic structure, avoiding direct rigid clamping that causes deformation of the clamping part of the steel pipe and damage to the steel pipe. Since the internal rotation of the buffer block is connected to a rotating roller, the rotating roller will come into contact with the steel pipe, and as the squeezing force increases, the rotating roller moves into the slide groove along with the buffer block, causing the rotating rod of the rotating roller to move into the driving groove, and finally contact the surface of the transmission belt, and squeeze the transmission belt.

At the same time, during the welding process, the electric push rod on the production line works together to move the equipment upward and to the designated position as a whole, that is, the transportation of the steel pipe is completed while the repair welding of the defective steel pipe is completed, and then the operation of automatic feeding and welding is realized, which greatly improves the production efficiency. At the same time, the defective steel pipes can be processed in a unified manner, avoiding the problem of manual processing after production is completed.

[0021] 2. The steel structure processing welding equipment has a convenient feeding mechanism. When the second motor is working, it will drive the connecting rod to rotate, so that the transmission belt rotates along the outer surface of the guide roller and the connecting rod, that is, the rotating rod is finally controlled to drive the rotating roller to rotate, so that the steel pipe in contact with the rotating roller starts to rotate, that is, the steel pipe is in a rotating state when the welding head starts to repair the welding part of the steel pipe, thereby realizing all-round repair welding of the welding parts of the two sections of steel pipes, which greatly improves the degree of automation and the efficiency of repair welding.

[0041] An elastic plate 415 is fixedly connected inside the plug-in board 414 . The elastic plate 415 is configured as a corrugated plate. An extrusion plate 416 is fixedly connected to one end of the elastic plate 415 away from the buffer block 413 . The extrusion plate 416 is fixedly plugged inside the clamping block 411 .
