Description

Technical Field

[0001] This invention relates to the field of industrial production technology, specifically to an angle-adjustable welding processing device for boilers. Background Technology

[0002] As an important energy conversion device, the safety and stability of boilers are of paramount importance. Welding technology directly affects the structural strength and performance of boilers. With the development of the power generation equipment manufacturing industry, the requirements for boiler welding processes are becoming increasingly stringent. Problems with traditional welding processes are becoming more and more prominent, such as defects like porosity and incomplete penetration, which seriously affect the safe operation of boilers. Therefore, the development of welding processing equipment with adjustable angles and strong adaptability has become the key to improving boiler welding quality and production efficiency.

[0003] During the welding process, the boiler is large in size and requires workers to operate a crane to lift it and adjust it to a position that is convenient for welding. The adjustment process consumes a lot of time, resulting in low welding efficiency and hindering the efficient progress of the welding work.

[0004] Before welding, the boiler is in a split state. During welding, the staff operates the equipment to bend and close it. If the temporary weld at the closure point of the boiler falls off due to excessive force during the welding process, the rebounding boiler will pose a threat to the safety of the surrounding staff.

[0005] To address this, an angle-adjustable welding processing device for boilers is proposed. Summary of the Invention

This ensures that the first and second clamping plates are stable and do not wobble during the clamping of the furnace body. When the furnace body needs to be rotated to adjust the welding angle, the operator controls the electric drive wheel to rotate inside the second clamping plate, thereby rotating the furnace body to adjust its position for welding work at different points.

[0018] 3. The two furnace bodies are initially joined together by the setting of the shafts on both sides. The operator controls the rotation of the gear shaft to move the furnace body above the loading plate by the gear belt. This makes it easy to move and adjust the position of the furnace body when welding, so as to achieve the purpose of rapid welding. Attached Figure Description

[0035] Embodiments of the present invention

[0036] Please see Figure 1 , Figure 2 and Figure 7An adjustable welding processing device for boilers includes a loading plate 1 and a sliding frame 3 slidably connected above the loading plate 1. A furnace body 5 is provided above the loading plate 1. The sliding frame 3 includes a positioning component 31, which includes a limiting chamber 316, a frame-shaped sliding plate 317, and a second spring 318. A positioning box 311 is symmetrically slidably connected inside the sliding frame 3. A second slider 315 is slidably connected to the middle of the positioning box 311. A first slider 312 is symmetrically slidably connected to the upper and lower sides of the positioning box 311 with the second slider 315 as the center. A first roller 314 is rotatably connected to the end of the first slider 312 near the furnace body 5. A first spring 313 is fixedly connected between the first slider 312 and the positioning box 311. The limiting chamber 316 is fixedly connected to the middle of the outer wall of the positioning box 311. A frame-shaped sliding plate 317 is slidably connected inside the limiting chamber 316. The upper and lower sides of the frame-shaped sliding plate 317 are fixedly connected to the first slider 312. A second spring 318 is connected to the frame-shaped slide plate 317, and a vertical detector 3110 is installed inside the frame-shaped slide plate 317. A third spring 319 is fixedly connected between the end of the second slider 315 near the limiting chamber 316 and the limiting chamber 316. A first support plate 3111 is fixedly connected to the top of the positioning box 311. A motor 4 is fixedly connected to the top of the sliding frame 3. A second support plate 3112 is fixedly connected to the telescopic end of the motor 4. The top of the first support plate 3111 is fixedly connected to the lower surface of the second support plate 3112. Positioning barrels 3113 are symmetrically slidably connected to the side walls of the sliding frame 3. The positioning barrels 3113 are fixedly connected to the bottom of the first support plate 3111. The recessed center of the positioning barrel 3113 is horizontal with the height of the limiting chamber 316. The first slider 312 and the frame-shaped slide plate 317 are perpendicular to each other. A controller is installed inside the sliding frame 3. The controller is electrically connected to the vertical detector 3110 and the motor 4.

[0037] In practical applications, the embodiments of the present invention are as follows:

[0038] In use, the operator assembles the furnace body 5 and places it on top of the loading plate 1. Then, the operator operates the motor 4 to extend. During this movement, the motor 4 drives the second support plate 3112 and the first support plate 3111 upwards together. The upward movement of the first support plate 3111 drives the positioning box 311 upwards as well. The upward movement of the positioning box 311 causes the second slider 315 and the first roller 314 to roll on the outer wall of the motor 4. When the symmetrical first roller 314 rolls against the outer wall of the motor 4, the curved surface of the outer wall of the motor 4 causes the first roller 314 to move towards the limiting chamber 316. During compression, since the two first sliders 312 are symmetrically arranged above and below the second slider 315, when the second slider 315 is horizontal with the axis of the motor 4, the first rollers 314 at both locations are compressed by the motor 4 to the same extent. When the first rollers 314 at both locations move to the same extent, the frame-shaped slide plate 317, which is flexibly connected between the two first sliders 312 by the second spring 318, will be in a vertical state. When the frame-shaped slide plate 317 is in a vertical state, the vertical detector 3110 detects the state of the frame-shaped slide plate 317 and sends a signal to the motor 4, causing the motor 4 to stop extending when the axis of the limiting chamber 316 and the furnace body 5 is horizontal.

[0039] At this time, because the positioning box 311 and the positioning barrel 3113 are fixedly connected by the first support plate 3111, and the recessed center of the positioning barrel 3113 is horizontal with the height of the second slider 315, the positioning barrel 3113 will move together with the positioning box 311 when it moves, thereby limiting the motor 4 through the positioning barrel 3113. By moving the first rollers 314 at two locations and determining the vertical state of the frame-type sliding plate 317 by the vertical detector 3110, the positioning barrel 3113 can evenly clamp the two sides of the furnace body 5 in the horizontal direction, thereby maximizing the stability of the furnace body 5 when limiting it, thereby reducing the gap between the two furnace bodies 5 after they are closed, and ensuring the efficient progress of the welding work.

[0040] Please see Figure 1 , Figures 8 to 10The sliding frame 3 also includes a hoisting and fixing assembly 32, which includes a round rod 326, a second gear 328, and a telescopic rod 3213. Cylinders 321 are symmetrically fixedly connected to the top of the inner cavity of the sliding frame 3. First clamping plates 323 are fixedly connected to the telescopic ends of the cylinders 321. Fourth springs 322 are sleeved on the outer walls of the cylinders 321. The fourth springs 322 are fixedly connected to the top of the inner cavity of the sliding frame 3 and the upper surface of the first clamping plate 323. A drive turntable 324 is installed on the top of the sliding frame 3. A lead screw 325 is rotatably connected inside the drive turntable 324. A round rod 326 is fixedly connected to the bottom of the lead screw 325. Racks 327 are symmetrically arranged on the outer wall of the round rod 326. Second gears 328 meshing with racks 327 are symmetrically rotatably connected to the upper surface of the first clamping plate 323. A second clamping plate 329 is fixedly connected to the bottom of the round rod 326. A trapezoidal block 3210 is slidably connected inside the second clamping plate 329. A fifth spring 3211 is fixedly connected between the trapezoidal block 3210 and the second clamping plate 329. A telescopic rod 3213 is symmetrically slidably connected inside the first clamping plate 323. A vent pipe 3212 is fixedly connected between the first clamping plate 323 and the second clamping plate 329. An electric drive wheel 3214 is symmetrically rotatably connected inside the second clamping plate 329. An annular plate is provided on the top of the trapezoidal block 3210. A vent hole with the same diameter as the trapezoidal block 3210 is opened inside the second clamping plate 329. An air chamber is opened inside the first clamping plate 323. The telescopic rod 3213 is slidably connected inside the air chamber of the first clamping plate 323. The vent pipe 3212 is fixedly connected to the vent hole of the second clamping plate 329 and the air chamber of the first clamping plate 323. When the telescopic rod 3213 is extended, it engages with the second gear 328.

[0041] In practical applications, the embodiments of the present invention are as follows:

[0042] After the two furnace bodies 5 are clamped and closed by the positioning barrel 3113 and the first roller 314, the operator pushes the furnace body 5 between the first clamping plate 323 and the second clamping plate 329. During the movement, the furnace body 5 will exert upward pressure on the first clamping plate 323. When the outer wall of the furnace body 5 is in contact with the lower surface of the first clamping plate 323, the operator operates the drive turntable 324 to start rotating. The rotation of the drive turntable 324 drives the lead screw 325 to slide upward. The movement of the lead screw 325 drives the round rod 326 to slide through the interior of the first clamping plate 323. The upward movement of the round rod 326 drives the second clamping plate 329 to move upward together. After the second clamping plate 329 moves upward and is in contact with the inner cavity of the furnace body 5, the operator operates the drive turntable 324 to stop rotating and moves the furnace body 5 further into the interior of the first clamping plate 323 and the second clamping plate 329. The process of the furnace body 5 moving into the interior of the first clamping plate 323 and the second clamping plate 329... The trapezoidal block 3210 is pushed to slide into the second clamping plate 329. The fifth spring 3211 is elastically stretched during the pushing of the trapezoidal block 3210. When the trapezoidal block 3210 slides into the vent hole, the air inside the vent hole is pushed into the vent pipe 3212 by the trapezoidal block 3210 and transmitted to the air chamber of the first clamping plate 323 through the vent pipe 3212. After the air chamber inside the first clamping plate 323 is inflated, the telescopic rod 3213 is pushed out. After the telescopic rod 3213 is pushed out, it engages with the second gear 328, thereby fixing the position of the first clamping plate 323. This ensures that the first clamping plate 323 and the second clamping plate 329 are stable and do not shake during the clamping of the furnace body 5. When the furnace body 5 needs to be rotated to adjust the welding angle, the operator operates the electric drive wheel 3214 to rotate inside the second clamping plate 329, thereby driving the furnace body 5 to rotate and adjust its position to facilitate welding work at different points.

[0043] Please see Figures 3 to 6The loading plate 1 has rollers arranged in a linear array in the middle, and an auxiliary moving assembly 11 is provided inside the loading plate 1. Shafts 111 are symmetrically rotatably connected to both sides of the upper surface of the loading plate 1. A gear shaft 113 is rotatably connected inside the shafts 111, and a toothed belt 114 meshes with the outer wall of the gear shaft 113. A first gear 112 is fixedly connected to one end of the shaft 111 located outside the loading plate 1. The auxiliary moving assembly 11 also includes a horizontal plate 115, a toothed plate 116, and a special-shaped slide rod 1110. The horizontal plate 115 is slidably connected to the side wall of the loading plate 1, and the toothed plate 116 is symmetrically fixedly connected to both sides of the upper surface of the horizontal plate 115. A pedal 117 is slidably connected to the middle of the horizontal plate 115, and the pedal 117 and the horizontal plate 115 are fixedly connected. A sixth spring 118 is connected to the transverse plate 115, and an air guide groove 119 is provided inside the transverse plate 115. A special-shaped slide rod 1110 is slidably connected to the side of the air guide groove 119 near the loading plate 1. Pins 1111 are slidably connected inside the transverse plate 115 and on both sides of the special-shaped slide rod 1110. The first gear 112 and the toothed plate 116 mesh with each other. An air storage chamber is provided in the middle of the transverse plate 115 and below the pedal 117. The air storage chamber forms a closed space inside the transverse plate 115. The air guide groove 119 is connected to the air storage chamber. The middle part of the special-shaped slide rod 1110 is concave. The pins 1111 fit against the non-concave part of the outer wall of the special-shaped slide rod 1110. The magnetic poles of the special-shaped slide rod 1110 and the pins 1111 are opposite. The diameter of the special-shaped slide rod 1110 and the air guide groove 119 are equal.

[0044] In practical applications, the embodiments of the present invention are as follows:

[0045] After the furnace body 5 to be welded is placed on the loading plate 1, the worker closes the parts of the furnace body 5 that need to be welded and places them on the loading plate 1. Then, the worker steps down on the pedal 117. After the pedal 117 is stepped down, the air inside the air storage chamber enters the air guide groove 119. The air pressure inside the air guide groove 119 increases and pushes the shaped slide rod 1110 to slide inside it. After the shaped slide rod 1110 slides, its central recess aligns with the pin 1111. Under the magnetic attraction of the shaped slide rod 1110, the pin 1111 slides into the horizontal plate 115. After the pin 1111 is retracted into the horizontal plate 115, it is no longer locked to the inner cavity of the loading plate 1, allowing the horizontal plate 115 to... The plate can slide inside the loading plate 1. Then, the worker continues to step on the horizontal plate 115. The horizontal plate 115 moves downward, causing the toothed plate 116 to move downward as well. When the toothed plate 116 moves downward, it meshes with the first gear 112 and drives the shaft 111 to rotate. The rotation of the shaft 111 drives the toothed shaft 113 and the toothed belt 114 to rotate together. When the toothed belt 114 rotates to fit against the outer wall of the furnace body 5, the two furnace bodies 5 are initially closed by the setting of the shafts 111 on both sides. The worker controls the rotation of the toothed shaft 113 to drive the toothed belt 114 to move the furnace body 5 above the loading plate 1. This makes it easy to move and adjust the position of the furnace body 5 when welding, thereby achieving the purpose of rapid welding.
