Description

Technical Field

[0001] The invention belongs to the technical field of welding equipment, in particular to a welding platform for equipment processing. Background Art

[0002] High-pressure boiler equipment is widely used in many fields, such as the power industry, chemical industry and other industrial fields. Existing high-pressure boilers are all manufactured through welding processes, so the welding quality directly determines the airtightness and service life of the high-pressure boiler. Due to the large size of high-pressure boilers, the deformation during the welding process continues to accumulate, eventually causing the deformation accumulation at the end opposite to the welding starting point to be too large and misalignment.

[0003] A Chinese invention patent publication number CN118478149B discloses an automated welding platform for special equipment. The key points of its technical solution are: it includes a base plate, a support frame is fixedly installed on the top surface of the base plate, a support plate is slidably connected to one side of the support frame, and a support hole is opened on the top surface of the base plate; a welding table, the welding table is rotatably connected to the inner circular wall of the support hole, and is used to support the boiler inner shell, and a protective box is provided on the top surface of the base plate; a hose is installed on the top surface of the protective box, and the air tightness of the weld is detected by utilizing the vacuum of the boiler inner shell and the detection liquid, and then the welding process of the boiler inner shell and the boiler end cover is completed, thereby achieving the automated welding effect of the boiler inner shell in the special equipment, which is convenient for the staff to assemble the boiler later.

[0004] However, the above technologies often have the following defects: for example, if the weld is not treated during the welding process, the stress in the weld cannot be eliminated in time; at the same time, spraying the weld with detection liquid can easily cause the weld to cool down too quickly, which can lead to increased weld hardness, cracks and deformation.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] Example 1: Figure 1 and Figure 2 As shown, the upper surface of the base plate 1 of the embodiment of the present invention is evenly fixed with support rollers 2 for supporting the boiler drum, so that the boiler drum can rotate more smoothly during the welding process.

[0030] like Figures 1 to 7 As shown, a bracket 4 is fixedly installed on the upper part of the base plate 1, and a guide seat 5 is provided on the lower middle side of the bracket 4. At the same time, a mounting seat 3 is fixed in the middle of the upper surface of the base plate 1, and an arc-shaped clamping sleeve 6 for clamping the boiler barrel is movably provided on the mounting seat 3 and the guide seat 5. The arc-shaped clamping sleeve 6 includes an arc-shaped clamping plate 60, and a clamping assembly 7 for driving the arc-shaped clamping sleeve 6 to clamp the boiler barrel is provided between the two arc-shaped clamping sleeves 6. The clamping assembly 7 includes a fixed seat 70, and a fixed seat 70 is symmetrically provided on the outer side of the arc-shaped clamping plate 60. An electromagnetic pull rod 71 is provided on the fixed seat 70, and the protruding end of the electromagnetic pull rod 71 is connected to a lifting rod 72. The upper end of the lifting rod 72 passes through the arc-shaped clamping plate 60 and is fixedly connected to the adjacent arc-shaped clamping plate 60. The electromagnetic pull rod 71 that is energized pulls the lifting rod 72 downward, thereby pushing the lower arc-shaped clamping plate 60 in the opposite direction, so that the arc-shaped clamping plates 60 on the upper and lower sides clamp the boiler barrel.

[0031] The opposite sides of the two arc-shaped clamping plates 60 are evenly provided with connecting grooves 600 with L-shaped cross sections, and an arc-shaped slide rail 61 is slidingly arranged in the connecting groove 600. A woven thermal insulation layer 62 is provided between the two arc-shaped slide rails 61. The woven thermal insulation layer 62 is a multi-layer thermal insulation layer made of rock wool cloth with thermal insulation effect, and a connecting plate 63 for limiting the distance between the two arc-shaped slide rails 61 is provided on the outside of the woven thermal insulation layer 62. An arc-shaped slide plate 14 is symmetrically arranged in the mounting seat 3, and an arc-shaped clamping plate 60 is provided with an arc-shaped slide groove 601 matching the arc-shaped slide plate 14. The arc-shaped clamping plates 60 arranged opposite to each other on the left and right are connected by the connecting plate 63, so that the two boiler barrels to be welded remain aligned during welding, and the welding area is shielded and closed by the woven thermal insulation layer 62, which avoids the weld after welding from being directly exposed to the external environment, causing the weld to cool down too quickly, resulting in stress concentration and cracking.

[0032] like Figure 4 and Figure 5 As shown, a drive motor 80 is provided on the bracket 4, and a servo motor is selected as the drive motor, and a worm 81 is provided at the output end of the drive motor 80. A mounting slot is provided in the middle of the bracket 4, and a transmission shaft 82 is rotatably provided in the mounting slot, and a worm wheel 83 matching the worm 81 is fixedly provided in the middle of the transmission shaft 82. Both ends of the transmission shaft 82 pass through the outside of the bracket 4 and are provided with a driving gear 84 for driving the arc-shaped clamping plate 60 to rotate, and the outer side of the arc-shaped clamping plate 60 is evenly provided with tooth grooves matching the driving gear 84. The worm 81 is driven to rotate by the drive motor 80, and the meshing transmission between the worm 81 and the worm wheel 83 enables the transmission shaft 82 to obtain a larger torque, so that the transmission shaft 82 has sufficient power to drive the driving gear 84 to rotate, and then the driving gear 84 pushes the arc-shaped clamping sleeve 6 clamping the boiler drum to perform self-rotating rotation.

[0033] An electric welding gun 9 is fixedly mounted on the bracket 4, and a gun head of the electric welding gun 9 is provided with a fixed sleeve 10 that passes through the movable part of the arc-shaped clamping sleeve 6. A sandblasting tube 11 is symmetrically arranged on the fixed sleeve 10 close to the boiler barrel. A sandblasting machine 12 is provided on one side of the base plate 1. The sandblasting machine 12 is connected to the sandblasting tube 11 through a flexible tube, so that the weld surface can be sandblasted during the welding process, so that rust or oil stains on the weld surface are removed, thereby improving the welding quality of the weld. At the same time, the weld after welding is sandblasted, and the stress on the weld surface is eliminated under the continuous impact of the sand particles. At the same time, the sprayed sand particles are stored in the inner cavity of the arc-shaped clamping sleeve 6, so that the sand particles cover and insulate the weld after welding.

[0034] The inner side of the arc-shaped clamping plate 60 is inlaid with an anti-skid plate 13, and the anti-skid plate 13 is evenly provided with anti-skid patterns on the side contacting the boiler drum, thereby preventing relative displacement during the rotation of the boiler drum driven by the arc-shaped clamping plate 60.

[0035] like Figure 4 As shown, the angle between the sandblasting tube 11 and the normal line of the outer contour of the boiler tube to be welded is 45 degrees, so that the sand particles sprayed through the sandblasting tube 11 will not fly into the welding area after colliding with the boiler tube wall.

[0036] Example 2: Figure 8 As shown, an air storage cavity is provided in the fixed seat 70 of the embodiment of the present invention, and a piston plate 15 is slidably provided in the air storage cavity, and the piston plate 15 is fixedly connected to the output end of the electromagnetic pull rod 71. An exhaust through hole connected to the air storage cavity is provided on the outer side of the fixed seat 70 near one end of the electromagnetic pull rod 71, and an air guide pipe 16 is provided at the exhaust through hole, and the exhaust port of the air guide pipe 16 is aligned with the upper end face of the arc-shaped clamping plate 60 installed on the guide seat 5, so that when the electromagnetic pull rod 71 is energized and the lifting rod 72 is pulled downward, the arc-shaped clamping plates 60 on the upper and lower sides move toward each other for closed clamping, so that the output end of the electromagnetic pull rod 71 drives the piston plate 15 to move downward, thereby squeezing the air in the air storage cavity, and then the air in the air storage cavity is discharged through the air guide pipe 16, and the discharged air is aligned with the end face of the arc-shaped clamping plate 60 for dust blowing treatment, so as to avoid the clamping effect of the arc-shaped clamping plate 60 being affected by impurities on the end face of the arc-shaped clamping plate 60.

[0037] Working principle: During operation, the two boiler barrels to be welded are placed on the supporting roller 2, and the welding part of the boiler barrel is aligned with the electric welding gun 9. The electromagnetic pull rod 71 is first controlled to be energized to make the electromagnetic pull rod 71 pull the lifting rod 72 downward, so that the fixing seat 70 pushes the lower arc-shaped clamping plate 60 in the opposite direction, so that the arc-shaped clamping plates 60 on the upper and lower sides clamp the boiler barrel. At the same time, the connecting plate 63 is used to align the end faces of the two boiler barrels to be welded, and the woven insulation layer 62 and the arc-shaped clamping plate 60 are used to form a working chamber isolated from the external environment, so that the sandblasting machine 12 can be used to provide high-speed moving sand particles to the sandblasting tube 11, so that the surface of the boiler barrel in the area to be welded is smooth. The rust or oil stains on the surface are cleaned, and the drive motor 80 is used to drive the worm 81 to rotate. The meshing transmission between the worm 81 and the worm wheel 83 allows the transmission shaft 82 to obtain a larger torque, so that the transmission shaft 82 has enough power to drive the drive gear 84 to rotate, and then the drive gear 84 pushes the arc-shaped clamping sleeve 6 that clamps the boiler barrel to rotate. The cleaned weld is welded by the electric welding gun 9, and the high-speed moving sand is used to collide with the weld surface after welding, so that the stress on the weld surface is eliminated, and the sprayed sand is stored in the inner cavity of the arc-shaped clamping sleeve 6, so that the sand covers and insulates the weld after welding.
