Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to a welding device for oil and gas processing equipment. Background Technology

[0002] Oil and gas processing equipment is a complete set of devices used for the purification and separation of crude oil and associated gas after oil and gas extraction. Its core functions include three-phase separation of oil, gas, and water, dehydration, desulfurization, desalination, and impurity removal. It includes pipelines, separators, heat exchangers, buffer tanks, and filter devices, among other pressure-bearing components. It is suitable for operating conditions in oilfield stations and offshore platforms, ensuring that oil and gas are transported in compliance with standards, while simultaneously recovering wastewater and light hydrocarbons, reducing corrosion and safety hazards. Existing oil and gas equipment often uses pipelines for connection, and the connection between multiple pipelines typically requires intelligent welding equipment.

[0003] When using welding equipment for pipeline welding, the clamping structure is generally used to hold the outer wall of the pipe for positioning, and then a laser welding machine is used for butt welding. Currently, most conventional clamping components use rigid chuck structures. When clamping small-diameter pipes, the effective contact area between the chuck and the outer wall of the pipe is very limited. The concentrated clamping force can easily squeeze the thin-walled pipe, causing pipe wall deformation and damage, peeling and damage of the outer anti-corrosion coating. Insufficient clamping friction can also cause slippage during pipeline welding, directly leading to weld misalignment, excessive coaxiality of pipe fittings, and significantly reducing the quality of laser weld formation. Summary of the Invention

[0004] The purpose of this invention is to provide a welding device for oil and gas processing equipment to solve the problems mentioned in the background art.

[0009] The connecting mechanism is located above the support frame. The connecting mechanism includes a fixed shell that is fixedly installed on the side of the clamping block, and two grooves are provided through the connecting strip.

[0010] Preferably, two rotating shafts are rotatably mounted on the side of the support plate via bearings, and the outer wall of the rotating shafts is fixedly connected to one end of the arc-shaped strip.

[0011] Preferably, an adjusting column is fixedly installed through the side of the arc-shaped strip, an mounting plate is fixedly installed on the side of the support plate, a cylinder is fixedly installed on the bottom surface of the mounting plate, and a lifting plate is fixedly installed on the upper end of the cylinder through the mounting plate.

[0012] Preferably, two concave frames are fixedly installed on the top surface of the lifting plate, and two adjusting frames are fixedly installed on the top surface of the concave frames. The inner wall of the adjusting frame is slidably connected to the outer wall of the adjusting column. An arc-shaped groove is provided on the side of the support plate, and the inner wall of the arc-shaped groove is slidably connected to the outer wall of the adjusting column.

[0013] Preferably, a T-shaped block is fixedly installed on the side of the concave frame, a T-shaped groove is provided on the side of the support plate, the outer wall of the T-shaped block is slidably connected to the inner wall of the T-shaped groove, the top surface of the support plate is set in an arc shape, and a rubber pad is fixedly installed on the top surface of the support plate.

[0014] Preferably, the movable plate is slidably installed with two limiting rods, the two ends of which are fixedly connected to the inner wall of the support frame. A motor is fixedly installed on the side of the support frame. A screw is threaded through the movable plate, and the two ends of the screw are rotatably connected to the inner wall of the support frame through bearings. The output rod of the motor is fixedly connected to one end of the screw.

[0015] Preferably, a fixing block is fixedly installed on the side of the clamping block, and fixing strips are fixedly installed on both sides of the fixing block, with a motor fixedly installed on the side of the fixing strips.

[0016] Preferably, the output end of the motor rotates through the fixing strip and is fixedly installed with a gear, the outer wall of the arc plate is fixedly installed with an arc gear ring, the outer wall of the gear meshes with the outer wall of the arc gear ring, and the bottom surface of the reinforcing block and the bottom surface of the clamping block are both provided with anti-slip grooves.

[0017] Preferably, the outer wall of the fixed shell is slidably connected to the inner wall of the tank, and two movable blocks are slidably installed on the inner wall of the fixed shell. A locking block is fixedly installed on the side of the movable block, and the locking block engages with the connecting strip.

[0018] Preferably, the two movable blocks are elastically connected to each other by an elastic element on their sides, and a pressing plate is fixedly installed on the top surface of the movable blocks. The fixed shell is provided with two through grooves, and the inner wall of the through grooves is slidably connected to the side of the pressing plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention places the pipe on a support plate, activates a cylinder to drive the lifting plate to rise as a whole, and simultaneously drives the upper concave frame to move upward. The concave frame moves in conjunction with the adjusting frame, causing the adjusting column inside the frame to deflect the arc strip at a corresponding angle. The arc strip pulls the connecting strip, causing multiple sets of clamping blocks to simultaneously close and tighten around the outer wall of the pipe. Then, a motor is started to drive the gear to rotate. The gear meshes with the arc-shaped gear ring, causing the arc plate to rotate synchronously. The reinforcing block on the arc plate deflects accordingly, providing secondary pressure and reinforcement to the outer wall of the pipe from the other side. The clamping blocks and reinforcing blocks work together to encircle the pipe, significantly increasing the overall stress area of ​​the outer wall of the pipe, making the stress distribution on the pipe wall uniform, effectively avoiding extrusion deformation, peeling and damage of the anti-corrosion coating. At the same time, the multi-point encircling structure increases the clamping friction, preventing the pipe from slipping or misaligning during welding, ensuring the coaxiality of the pipe fittings, and significantly improving the forming accuracy and overall welding quality of the laser welding seam.

[0021] With anti-slip grooves on the bottom surfaces of both sets of clamping blocks and reinforcing blocks, and the two types of anti-slip grooves arranged horizontally and vertically respectively, when the clamping blocks and reinforcing blocks simultaneously grip the pipe for welding operations, the horizontal anti-slip grooves can restrict the axial movement of the pipe, and the vertical anti-slip grooves can prevent the circumferential rotation of the pipe. The bidirectional limiting cooperation greatly improves the clamping and anti-slip effect, effectively avoids pipe offset and misalignment, stably ensures the pipe docking accuracy, and significantly improves the quality of laser welding.

[0022] By pressing the button, the moving block and the clamping block are moved synchronously. The moving block compresses the internal elastic element to accumulate force, and the clamping blocks on both sides are pushed inward. When the clamping blocks are completely retracted into the limiting area inside the fixed shell, the locking structure between the fixed shell and the connecting strip is released, and the two can be quickly separated, thereby completing the disassembly and separation of the clamping block. The entire disassembly and assembly process does not require additional tools, and the clamping block can be replaced and repaired conveniently and quickly, reducing the downtime for equipment maintenance and effectively improving the overall work efficiency of pipeline welding operations.

[0036] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0038] like Figures 1-8 As shown, this application provides a welding device for oil and gas processing equipment, including: a support frame 1, a welding assembly 101 mounted on the top surface of the support frame 1, a fixed plate 102 and a movable plate 103 mounted on the top surface of the support frame 1, and two support plates 104 fixedly mounted on the top surfaces of both the fixed plate 102 and the movable plate 103.

[0039] The clamping mechanism 2 is located above the support frame 1. The clamping mechanism 2 includes two clamping blocks 215 located above the support plate 104. A connecting strip 214 is provided above the clamping blocks 215, and an arc-shaped strip 213 is fixedly installed on the side of the connecting strip 214.

[0040] Specifically, such as Figures 3-4 As shown, two rotating shafts 212 are rotatably mounted on the side of the support plate 104 via bearings, and the outer wall of the rotating shaft 212 is fixedly connected to one end of the arc-shaped strip 213.

[0041] In this embodiment: the rotating shaft 212 allows the arc-shaped strip 213 to swing, further ensuring that the clamping block 215 swings to clamp and fix pipes of different sizes.

[0042] Specifically, such as Figure 3 As shown, an adjusting column 216 is fixedly installed through the side of the arc-shaped strip 213, an mounting plate 205 is fixedly installed on the side of the support plate 104, a cylinder 206 is fixedly installed on the bottom surface of the mounting plate 205, and a lifting plate 207 is fixedly installed on the upper end of the cylinder 206 through the mounting plate 205.

[0043] In this embodiment: the cylinder 206 is connected and fixed by the mounting plate 205, and the cylinder 206 drives the lifting plate 207 to move up and down.

[0044] Specifically, such as Figures 3-4 As shown, two concave frames 208 are fixedly installed on the top surface of the lifting plate 207, and two adjusting frames 211 are fixedly installed on the top surface of the concave frames 208. The inner wall of the adjusting frame 211 is slidably connected to the outer wall of the adjusting column 216. An arc groove 217 is provided on the side of the support plate 104, and the inner wall of the arc groove 217 is slidably connected to the outer wall of the adjusting column 216.

[0045] In this embodiment: when the lifting plate 207 moves, it drives the concave frame 208 to move, the concave frame 208 drives the adjusting frame 211 to move, the adjusting frame 211 drives the adjusting column 216 and the arc strip 213 to swing at a certain angle, and the arc groove 217 limits the adjusting column 216, so that the swing of the adjusting column 216 and the arc strip 213 is more stable and less prone to deviation.

[0046] Specifically, such as Figure 3 As shown, a T-shaped block 209 is fixedly installed on the side of the concave frame 208, and a T-shaped groove 210 is provided on the side of the support plate 104. The outer wall of the T-shaped block 209 is slidably connected to the inner wall of the T-shaped groove 210. The top surface of the support plate 104 is arc-shaped, and a rubber pad 204 is fixedly installed on the top surface of the support plate 104.

[0047] In this embodiment: the T-shaped groove 210 is used to limit the T-shaped block 209, so that the T-shaped block 209 and the concave frame 208 move more stably. The top surface of multiple rubber pads 204 is provided with horizontal and vertical friction grooves. The horizontal and vertical friction grooves increase the friction between the rubber pads 204 and the outer wall of the pipe, making the pipe less prone to displacement.

[0048] Specifically, such as Figures 1-2 As shown, the movable plate 103 is slidably installed with two limiting rods 201. The two ends of the limiting rods 201 are fixedly connected to the inner wall of the support frame 1. The motor 203 is fixedly installed on the side of the support frame 1. The movable plate 103 is threadedly installed with a screw 202. The two ends of the screw 202 are rotatably connected to the inner wall of the support frame 1 through bearings. The output rod of the motor 203 is fixedly connected to one end of the screw 202.

[0049] In this embodiment: the motor 203 drives the screw 202 to rotate, the screw 202 drives the moving plate 103 to move, and further drives the support plate 104 and the pipe to move, so that the two pipes are connected and welded. The limiting rod 201 limits the moving plate 103, so that the moving plate 103 and the upper pipe move more stably.

[0050] The reinforcement mechanism 3 is located above the support frame 1. The reinforcement mechanism 3 includes reinforcement blocks 301 hinged to both sides of the clamping block 215. An arc plate 306 is fixedly installed on the outer wall of the reinforcement block 301.

[0051] Specifically, such as Figure 7 As shown, a fixing block 302 is fixedly installed on the side of the clamping block 215, and fixing strips 303 are fixedly installed on both sides of the fixing block 302. A motor 304 is fixedly installed on the side of the fixing strips 303.

[0052] In this embodiment: the motor 304 is fixed by the fixed block 302, and the reinforcing block 301 further clamps and fixes the pipe.

[0053] Specifically, such as Figures 6-7 As shown, the output end of the motor 304 rotates through the fixing strip 303 and is fixedly installed with a gear 305. An arc-shaped gear ring 307 is fixedly installed on the outer wall of the arc plate 306. The outer wall of the gear 305 meshes with the outer wall of the arc-shaped gear ring 307. Anti-slip grooves 308 are provided on the bottom surface of the reinforcing block 301 and the bottom surface of the clamping block 215.

[0054] In this embodiment: the motor 304 drives the gear 305 to rotate, which in turn drives the arc-shaped gear ring 307 to rotate at a certain angle, causing the arc-shaped plate 306 to rotate synchronously. The reinforcing block 301 on the arc-shaped plate 306 deflects accordingly, providing secondary compression and reinforcement to the outer wall of the pipe from the other side. The clamping block 215 and the reinforcing block 301 work together to encircle the pipe, significantly increasing the overall stress area of ​​the outer wall of the pipe, ensuring uniform stress distribution, and effectively preventing extrusion deformation, peeling and damage to the anti-corrosion coating. Simultaneously, the multi-point encircling structure increases the clamping friction, facilitating welding... During the process, the pipeline will not slip or misalign, ensuring the coaxiality of the pipe fittings and significantly improving the forming accuracy of the laser welding seam and the overall welding quality. The anti-slip grooves 308 are arranged horizontally and vertically respectively. When the clamping block 215 and the reinforcing block 301 simultaneously hold the pipe fittings to carry out welding operations, the horizontal anti-slip grooves 308 can restrict the axial movement of the pipe fittings, and the vertical anti-slip grooves 308 can prevent the circumferential rotation of the pipe fittings. The bidirectional limiting cooperation greatly improves the clamping and anti-slip effect, effectively avoids the pipe fittings from shifting or misaligning, stably ensures the pipe fittings docking accuracy, and significantly improves the forming quality of laser welding.

[0055] The connecting mechanism 4 is located above the support frame 1. The connecting mechanism 4 includes a fixed shell 402 fixedly installed on the side of the clamping block 215, and the connecting strip 214 has two through grooves 401.

[0056] Specifically, such as Figures 5-8 As shown, the outer wall of the fixed shell 402 is slidably connected to the inner wall of the groove 401. Two moving blocks 403 are slidably installed on the inner wall of the fixed shell 402. A locking block 404 is fixedly installed on the side of the moving block 403, and the locking block 404 is engaged with the connecting strip 214.

[0057] In this embodiment: the outer wall of the fixed shell 402 is slidably connected to the inner wall of the groove 401, the fixed shell 402 limits the connecting strip 214, and the locking block 404 is engaged with the connecting strip 214, thereby connecting and fixing the fixed shell 402 and the connecting strip 214, and further fixing the clamping block 215.

[0058] Specifically, such as Figure 8 As shown, two movable blocks 403 are elastically connected to each other by elastic members 405 on their sides. A pressing plate 407 is fixedly installed on the top surface of the movable block 403. The fixed shell 402 is provided with two through grooves 406, and the inner wall of the through grooves 406 is slidably connected to the side of the pressing plate 407.

[0059] In this embodiment: by pressing the button 407, the moving block 403 and the locking block 404 are moved synchronously, and the two locking blocks 404 on both sides retract to the middle. When the locking block 404 is completely retracted into the inner limiting area of ​​the fixed shell 402, the locking structure between the fixed shell 402 and the connecting strip 214 is released, and the two can be quickly separated, thereby completing the disassembly and separation of the clamping block 215. The entire disassembly and assembly process does not require additional tools, thus improving work efficiency.

[0060] The specific solution is as follows: The pipe is placed on two support plates 104. The cylinder 206 is activated to drive the lifting plate 207 to rise, simultaneously causing the upper concave frame 208 to move upwards. The concave frame 208, in conjunction with the adjusting frame 211, moves synchronously, driving the adjusting column 216 to deflect the arc-shaped strip 213 by a corresponding angle. The arc-shaped strip 213 pulls the connecting strip 214, causing multiple clamping blocks 215 to simultaneously close and tighten around the outer wall of the pipe. Then, the motor 304 is started to drive the gear 305 to rotate. The gear 305 meshes with the arc-shaped gear ring 307, causing the arc plate 306 to rotate synchronously. The reinforcing block 301 on the arc plate 306 deflects accordingly, providing secondary pressure and reinforcement to the outer wall of the pipe from the other side. The clamping blocks 215 and the reinforcing blocks 301 work together to encircle the pipe, significantly increasing the overall stress area of ​​the outer wall of the pipe, ensuring uniform stress distribution, and effectively preventing compression deformation, peeling and damage to the anti-corrosion coating. Simultaneously, the multi-point encircling structure increases the clamping friction. By activating the motor 204… 3. The screw 202 is driven to rotate, which in turn moves the moving plate 103 and the pipe above it, allowing the two pipes to connect. The welding assembly 101 is driven by a motor and a threaded rod, which moves the laser welder to a suitable position. The laser welder can rotate circumferentially to weld the pipe. When the clamping block 215 needs maintenance or replacement, the button 407 is pressed, which moves the moving block 403 and the locking block 404 synchronously. The moving block 403 presses the internal elastic element 405 to complete the storage of force. The two locking blocks 404 are pushed towards the middle. When the locking block 404 is completely retracted into the internal limiting area of ​​the fixed shell 402, the locking structure between the fixed shell 402 and the connecting strip 214 is released, and the two can be quickly separated, thereby completing the disassembly and separation of the clamping block 215. The entire disassembly and assembly process does not require additional tools, and the clamping block 215 can be replaced and repaired conveniently and quickly, reducing the downtime for equipment maintenance and effectively improving the overall work efficiency of pipe welding operations.
