Description

Technical Field

[0001] This invention belongs to the field of engineering pipeline welding technology, specifically a pipeline welding equipment for building engineering. Background Technology

[0002] Pipelines have a wide range of applications, mainly used in industrial installations such as water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, and water conservancy projects. They are an indispensable part of building construction. During building construction, pipelines often need to be welded. There are many welding methods, and argon arc welding is currently a commonly used welding method in building construction.

[0003] Currently, in existing technologies, when extending and welding existing engineering pipelines, the existing pipeline is horizontally joined with the previously welded pipeline. Then, a track-type pipe welding machine is used to perform 360° rotation welding around the joint of the two pipelines. However, the entire process requires moving, joining, adjusting the angle, fixing, and welding the pipeline, which takes a long time. After 50% of the pipeline is welded, the positioning device is no longer needed on the pipeline surface. When the welder is welding the remaining position, the positioning device is in a stagnant state. After the pipeline is finished, the above operation is repeated, which wastes time. It is impossible to simultaneously move, join, adjust the angle, and fix the next pipeline while the track-type pipe welding machine is welding 50% of the pipeline, thus reducing the pipeline welding time.

[0004] Therefore, the present invention provides a pipe welding device for building engineering. Summary of the Invention

Swinging arms are oscillatingly connected to both sides of the auxiliary frame. A servo motor is fixedly installed on the outer surface of the auxiliary frame, and the drive shaft of the servo motor is fixedly connected to the outer surface of the swing arm. Two sets of anti-sway wheels are fixedly installed on the outer surface of one end of the swing arm, and the outer surfaces of the anti-sway wheels movably overlap the outer surface of the engineering pipe. A wear-resistant and anti-slip layer is fixedly connected to the outer surface of the anti-sway wheel. Multiple sets of damping support rods are fixedly installed on the inner wall of the anti-sway wheel. A semi-circular extrusion head is fixedly connected to the output end of the damping support rod, and the outer surface of the semi-circular extrusion head movably overlaps the inner wall of the wear-resistant and anti-slip layer.

[0007] Preferably, a circular track is provided on the top surface of the main frame at one side edge, and a four-point welded ring is fixedly installed on the top surface of the main frame at the other side edge.

[0008] Preferably, a movable platform is movably sleeved on the inner wall of the circular track, and an argon arc welding device is fixedly installed on the outer surface of the movable platform.

[0009] Preferably, four sets of argon arc welders are fixedly installed on the inner wall of the four-point welding ring, and the output points of the argon arc welders and the first argon arc welder are located on the surface of the engineering pipeline.

[0010] Preferably, multiple support arms are fixedly installed on the outer surface of the circular track and the four-point welded ring, and multiple sets of hydraulic rods are fixedly installed on the surface of the support arms.

[0011] Preferably, the output end of the hydraulic rod two is fixedly connected to an arc-shaped bonding plate two, and the outer surface of the arc-shaped bonding plate two is bonded to the outer surface of the engineering pipeline.

[0012] Preferably, the top surface of the support slide has two sets of slots, and two sets of hydraulic rods are fixedly installed on the top surface of the support slide and at the two side edges respectively. The top surface of the support slide is provided with an arc-shaped support plate, and the bottom surface of the arc-shaped support plate is provided with a connecting plate. The output end surface of the hydraulic rod is hinged to the bottom surface of the arc-shaped support plate, and a limit rod is fixedly connected to the bottom surface of the arc-shaped support plate.

[0013] Preferably, the outer surface of the limiting rod one is movably sleeved on the inner wall of the slot, a hard-touch buffer block is fixedly connected to the top outer surface of the arc-shaped support plate, an arc-shaped bonding plate one is provided on the outer surface of the hard-touch buffer block, and multiple limiting rods two are fixedly connected to the bottom surface of the arc-shaped bonding plate one, with the outer surface of the limiting rods two movably sleeved on the outer surface of the arc-shaped support plate.

[0014] Preferably, a main frame is fixedly connected to one side surface of the auxiliary frame, and movable rollers are provided on the outer surfaces of the main frame and the auxiliary frame. Multiple support sleeves are fixedly installed on the inner wall of the anti-sway wheel, and the position of the damping support rod is located on the inner wall of the support sleeve.

[0015] Preferably, the damping support rod includes an outer cylinder, an inner rod slidably inserted within the outer cylinder, and a piston fixed to the end of the inner rod. The outer peripheral wall of the piston is in a sealing sliding fit with the inner wall of the outer cylinder. An axial damping channel is formed inside the piston, and a valve core is slidably disposed within the damping channel. An annular throttling gap is formed between the valve core and the damping channel. During the reciprocating motion of the piston, the working medium generates a throttling effect through the annular throttling gap, thereby converting mechanical kinetic energy into heat energy for release.

[0016] The beneficial effects of this invention are as follows: 1. The pipe welding equipment for construction engineering described in this invention uses hydraulic rods inside both ends of a support slide to move a pair of arc-shaped support plates up and down, thereby adjusting the angle of both ends of the engineering pipe. This aligns one end of the new engineering pipe with the surface of the pipe being welded. During the alignment process, the support slide moves inside the moving track, bringing the surface of the engineering pipe into contact with the surface of the pipe being welded. A servo motor rotates the swing arm, causing the anti-sway wheels on the outer surface of the swing arm to press against the outer surface of the engineering pipe. The V-shaped support shape formed by the swing arm and the two sets of anti-sway wheels is used to perform four-point welding on the contact surfaces of the two engineering pipes through an argon arc welder inside a four-point welding ring. The four-point welding keeps the two engineering pipes in place and effectively reduces the risk of positional movement or displacement of the engineering pipes during subsequent operations. 2. The pipe welding equipment for construction engineering described in this invention, when the anti-sway wheel contacts the surface of the engineering pipe, the wear-resistant and anti-slip layer on the outer surface of the anti-sway wheel will preferentially contact the surface of the engineering pipe. The external impact will be directly transmitted to the interior of the damping support rod through the semi-circular extrusion head. When the damping support rod is displaced, the huge kinetic energy is converted into heat energy and released through the hydraulic throttling mechanism inside the damping support rod, thereby effectively avoiding rigid collisions, significantly reducing the impact peak, achieving a soft landing, and avoiding the wear of the anti-rust layer on the surface of the engineering pipe caused by friction between metals during the impact of metal objects; moreover, the wear resistance of the wear-resistant and anti-slip layer surface can effectively increase the anti-slip performance between the anti-sway wheel and the surface of the engineering pipe. 3. The pipe welding equipment for construction engineering described in this invention, in conjunction with pipe supports and hangers, defines the position of one of the engineering pipes. At this time, the main frame moves the circular track, and the welding contact point of the argon arc welder moves to the joint of the two engineering pipes. At this time, the moving table inside the circular track rotates around the engineering pipe and performs welding treatment through the gap of the argon arc welder. When the root weld of the two engineering pipes is 50% completed, the lifting device places the new engineering pipe on the top surface of the arc-shaped bonding plate. When the engineering pipe is pressed against the top surface of the arc-shaped bonding plate, the hard contact buffer rubber block between the arc-shaped support plate and the arc-shaped bonding plate compresses and deforms the hard contact of the engineering pipe, thereby providing impact buffer treatment for the compression of the engineering pipe. 4. The pipe welding equipment for construction engineering described in this invention, when the circular track and the four-point welding ring move to the outer surface of the engineering pipe under the movement of the main frame, the hydraulic rods on the outer surface of the support arm push the arc-shaped bonding plate two, so that the surface of the arc-shaped bonding plate two is attached to the outer surface of the engineering pipe. Multiple hydraulic rods two are used to support and limit the surface of the engineering pipe at multiple points, so that the two sets of engineering pipes will not have excessive shaking and positional displacement during subsequent welding. The engineering pipes that have been welded will have pipe supports installed on the surface of the engineering pipes, thereby limiting the surface position of the engineering pipes and distributing the weight of multiple engineering pipes for support.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4 and Figures 8 to 9 As shown, an embodiment of the present invention provides a pipe welding device for construction engineering, comprising an auxiliary frame 121 and a movable track 122 fixedly installed on the top surface of the auxiliary frame 121, a support slide 123 movably sleeved on the inner wall of the movable track 122, an engineering pipe 11 movably sleeved on the outer surface of the top of the support slide 123, swing arms 125 oscillatingly connected to both sides of the auxiliary frame 121, a servo motor 124 fixedly installed on the outer surface of the auxiliary frame 121, a drive shaft of the servo motor 124 fixedly connected to the outer surface of the swing arms 125, and two sets of anti-sway wheels 126 fixedly installed on the outer surface of one end of the swing arms 125, the outer surfaces of the anti-sway wheels 126 movably overlapping the engineering pipe 11. The outer surface of the pipeline 11; the outer surface of the anti-sway wheel 126 is fixedly connected to a wear-resistant and anti-slip layer 1264, the inner wall of the anti-sway wheel 126 is fixedly installed with multiple sets of damping support rods 1262, the output end of the damping support rod 1262 is fixedly connected to a semi-circular extrusion head 1263, the outer surface of the semi-circular extrusion head 1263 is movably overlapped on the inner wall of the wear-resistant and anti-slip layer 1264, one side surface of the auxiliary frame 121 is fixedly connected to the main frame 12, the outer surfaces of the main frame 12 and the auxiliary frame 121 are provided with movable rollers, the inner wall of the anti-sway wheel 126 is fixedly installed with multiple support sleeves 1261, and the position of the damping support rod 1262 is set on the inner wall of the support sleeve 1261; The damping support rod 1262 includes an outer cylinder, an inner rod slidably inserted inside the outer cylinder, and a piston fixed to the end of the inner rod. The outer peripheral wall of the piston and the inner wall of the outer cylinder are in a sealing sliding fit. An axial damping channel is opened inside the piston, and a valve core is slidably arranged in the damping channel. An annular throttling gap is formed between the valve core and the damping channel. During the reciprocating motion of the piston, the working medium generates a throttling effect through the annular throttling gap, thereby converting mechanical kinetic energy into heat energy and releasing it. The top surface of the support slide 123 has two sets of slots a1. Two sets of hydraulic rods a2 are fixedly installed on the top surface of the support slide 123 and at the two side edges respectively. An arc-shaped support plate a4 is provided on the top surface of the support slide 123. A connecting plate a3 is provided on the bottom surface of the arc-shaped support plate a4. The output end surface of the hydraulic rod a2 is hinged to the bottom surface of the arc-shaped support plate a4. A limiting rod a5 is fixedly connected to the bottom surface of the arc-shaped support plate a4. The outer surface of the limiting rod a5 is movably sleeved on the inner wall of the slot a1. A hard-touch buffer block a6 is fixedly connected to the top outer surface of the arc-shaped support plate a4. An arc-shaped bonding plate a7 is provided on the outer surface of the hard-touch buffer block a6. Multiple limiting rods a8 are fixedly connected to the bottom surface of the arc-shaped bonding plate a7. The outer surface of the limiting rods a8 is movably sleeved on the outer surface of the arc-shaped support plate a4. The two sets of anti-sway wheels 126 and the swing arm 125 form a V-shaped support groove.

[0022] The hydraulic rods a2 inside the two ends of the support slide 123 move the two ends of the arc support plate a4 up and down, thereby adjusting the angle of the two ends of the engineering pipe 11 so that one end of the new engineering pipe 11 is aligned with the surface of the engineering pipe 11 being welded. During the alignment of the engineering pipe 11, the support slide 123 moves inside the moving track 122, and the surface of the engineering pipe 11 comes into contact with the surface of the engineering pipe 11 being welded. The servo motor 124 rotates the swing arm 125, and the anti-sway wheel 126 on the outer surface of the swing arm 125 is pressed against the outer surface of the engineering pipe 11. The V-shaped support shape formed by the swing arm 125 and the two sets of anti-sway wheels 126 is used to perform four-point welding on the contact surface of the two engineering pipes 11 through the argon arc welder 1212 inside the four-point welding ring 1211. The four-point welding can limit the two engineering pipes 11 together and can also effectively reduce the position movement and displacement of the engineering pipes 11 in subsequent operations. The slot a1 serves as a floating guide channel for the limiting rod a5, and its cross-sectional profile is set to be larger than the mating section size of the limiting rod a5. When the support slide 123 causes the limiting rod a5 to change its tilt angle, the slot a1 provides sufficient clearance space to compensate for the horizontal displacement component caused by the angle change, thereby allowing the limiting rod a5 to smoothly perform the combined lifting and swinging motion within the slot a1. The two inclined surfaces of the V-shaped support groove are symmetrically distributed. When it comes into contact with the surface of the engineering pipe 11, regardless of the pipe diameter, its center line will automatically fall on the angle bisector of the V-shaped groove. Moreover, when the pipe is in an inclined state, one end of the V-shaped support bar will always be in contact with the surface of the pipe. This natural geometric characteristic enables the V-shaped support to achieve automatic centering, fixation and single-point support without the need for complex additional positioning mechanisms, which greatly improves the accuracy of assembly and processing. Moreover, the V-shaped support can form a symmetrical constraint on the pipe through two inclined surfaces, which can effectively limit the radial movement and rotation of the pipe around the axis. With the upper and lower clamping devices, the pipe can be positioned and clamped from four directions to ensure that the clamping force is evenly distributed and to avoid deformation or damage to the pipe due to uneven force. At the same time, the V-shaped support can reduce the contact area between the pipe and the support while firmly positioning the pipe, thereby effectively reducing the wear of the anti-corrosion layer on the pipe surface. When the anti-sway wheel 126 contacts the surface of the engineering pipe 11, the wear-resistant and anti-slip layer 1264 on the outer surface of the anti-sway wheel 126 will preferentially contact the surface of the engineering pipe 11. The external impact will be directly transmitted to the inside of the damping support rod 1262 through the semi-circular extrusion head 1263. When the damping support rod 1262 is displaced, the huge kinetic energy is converted into heat energy and released through the hydraulic throttling mechanism inside the damping support rod 1262, thereby effectively avoiding rigid collisions, significantly reducing the impact peak, achieving a soft landing, and preventing the wear of the anti-rust layer on the surface of the engineering pipe 11 due to friction between metals during the impact. Moreover, the wear resistance of the wear-resistant and anti-slip layer 1264 can effectively increase the anti-slip properties between the anti-sway wheel 126 and the surface of the engineering pipe 11. The position of one of the engineering pipes 11 is defined by the pipe support 111. At this time, the main frame 12 moves the circular track 127, causing the welding contact point of the argon arc welder 129 to move to the contact point of the two engineering pipes 11. The moving platform 128 inside the circular track 127 rotates around the engineering pipe 11, and the argon arc welder 129 welds the gap. When 50% of the root weld of the two engineering pipes 11 is completed... Then, with the help of the lifting device, the new engineering pipe 11 is placed on the top surface of the arc-shaped bonding plate a7. After the engineering pipe 11 is pressed against the top surface of the arc-shaped bonding plate a7, the hard contact buffer rubber block a6 between the arc-shaped support plate a4 and the arc-shaped bonding plate a7 compresses and deforms the hard contact of the engineering pipe 11, thereby providing impact buffering treatment for the compression of the engineering pipe 11. When 50% of the welding of the previous engineering pipe 11 is completed, the support slide 123 moves away from the bottom surface of the previous engineering pipe 11, and the new engineering pipe 11 is then... The new engineering pipe 11 is moved and its angle adjusted, and then fitted and connected to the surface of the previous engineering pipe 11 being welded. Once the previous engineering pipe 11 is welded, the next engineering pipe 11 can be welded directly. This shortens the time required to wait for the next engineering pipe 11 to be aligned, adjusted, and moved after the previous engineering pipe 11 is welded, thus reducing the welding time between the two engineering pipes 11. The preparation time for the next engineering pipe 11 is directly incorporated into the welding time of the previous engineering pipe 11.

[0023] like Figures 4 to 7 As shown, a circular track 127 is provided on the top surface of the main frame 12 and at one edge position, and a four-point welding ring 1211 is fixedly installed on the top surface of the main frame 12 and at the other edge position. A movable platform 128 is movably sleeved on the inner wall of the circular track 127, and an argon arc welder 129 is fixedly installed on the outer surface of the movable platform 128.

[0024] The position of one of the engineering pipes 11 is defined by the pipe support 111. At this time, the main frame 12 moves the circular track 127 and moves the welding contact point of the argon arc welder 129 to the joint of the two engineering pipes 11. The moving platform 128 inside the circular track 127 rotates around the engineering pipe 11 and welds the gap through the argon arc welder 129. When the root weld of the two engineering pipes 11 is 50% complete, the lifting device places the new engineering pipe 11 on the top surface of the arc-shaped bonding plate a7. When the engineering pipe 11 is pressed against the top surface of the arc-shaped bonding plate a7, the hard contact buffer rubber block a6 between the arc-shaped support plate a4 and the arc-shaped bonding plate a7 compresses and deforms the hard contact of the engineering pipe 11, thereby providing impact buffering treatment for the compression of the engineering pipe 11. Moreover, the limiting rod a5 on the bottom surface of the arc support plate a4 will be limited by the inside of the slot a1, and can only swing left and right, but cannot swing sideways, so that when the engineering pipe 11 is attached to the top surface of the arc bonding plate a7 and moves, it will not tilt to the side. Because the pipeline is a cylindrical structure, when the root weld bead is evenly distributed along the circumference and reaches a certain proportion, such as 50%, the weld metal has solidified and formed a certain structural strength. At this time, 50% of the weld points are sufficient to physically tie the two pipelines together and maintain their basic coaxiality, so that even if the pipeline is suspended, it will not tilt or deviate from its original position. The remaining 50% of the unwelded part will not be seriously misaligned due to the rigidity of the pipeline itself and the tension of the welded part. External fittings are high-value precision tooling equipment. In the construction of large-scale long-distance pipelines, if they must be removed only after 100% welding is completed, the equipment turnover rate will be extremely low. The design that they can be removed after 50% completion significantly shortens the occupation time of a single piece of equipment, thereby accelerating the overall construction progress.

[0025] like Figures 4 to 5 As shown, four sets of argon arc welding devices 1212 are fixedly installed on the inner wall of the four-point welding ring 1211. The output points of the argon arc welding devices 1212 and argon arc welding devices 129 are located on the surface of the engineering pipeline 11. Multiple support arms 1210 are fixedly installed on the outer surface of the circular track 127 and the four-point welding ring 1211. Multiple sets of hydraulic rods 1213 are fixedly installed on the surface of the support arms 1210. The output end of the hydraulic rods 1213 is fixedly connected to an arc-shaped bonding plate 1214. The outer surface of the arc-shaped bonding plate 1214 is bonded to the outer surface of the engineering pipeline 11.

[0026] When the circular track 127 and the four-point welding ring 1211 move to the outer surface of the engineering pipe 11 under the movement of the main frame 12, the hydraulic rod 1213 on the outer surface of the support arm 1210 pushes the arc-shaped bonding plate 1214, so that the surface of the arc-shaped bonding plate 1214 is attached to the outer surface of the engineering pipe 11. Multiple hydraulic rods 1213 are used to support and limit the surface of the engineering pipe 11 at multiple points, so that the two sets of engineering pipes 11 will not shake or shift their position during subsequent welding. After the engineering pipe 11 has been welded, pipe supports 111 will be installed on the surface of the engineering pipe 11 to limit the surface position of the engineering pipe 11 and distribute the weight of the multiple engineering pipes 11 for support.

[0027] Working principle: The position of one of the engineering pipes 11 is defined by the pipe support 111. At this time, the main frame 12 moves the circular track 127, and the welding contact point of the argon arc welder 129 moves to the joint of the two engineering pipes 11. The moving platform 128 inside the circular track 127 rotates around the engineering pipe 11 and welds the gap through the argon arc welder 129. When the root weld of the two engineering pipes 11 is 50% completed, the lifting device places the new engineering pipe 11 on the top surface of the arc-shaped bonding plate a7. When the engineering pipe 11 is pressed against the top surface of the arc-shaped bonding plate a7, the hard contact buffer rubber block a6 between the arc-shaped support plate a4 and the arc-shaped bonding plate a7 compresses and deforms the hard contact of the engineering pipe 11, thereby providing impact buffering treatment for the compression of the engineering pipe 11. At this time, the hydraulic rods a2 inside both ends of the support slide 123 move the arc-shaped support plate a4 up and down, thereby adjusting the angle of both ends of the engineering pipe 11, so that one end of the new engineering pipe 11 is aligned with the surface of the engineering pipe 11 being welded. During the alignment process, the support slide 123 moves inside the moving track 122, so that the surface of the engineering pipe 11 contacts and adheres to the surface of the engineering pipe 11 being welded. The servo motor 124 rotates the swing arm 125, so that the anti-sway wheels 126 on the outer surface of the swing arm 125 are pressed and adhered to the outer surface of the engineering pipe 11, using the V-shaped support shape formed by the swing arm 125 and the two sets of anti-sway wheels 126. Then, the contact surfaces of the two engineering pipes 11 are welded at four points using the argon arc welder 1212 inside the four-point welding ring 1211. Four-point welding can limit the two engineering pipes 11 together and effectively reduce the position movement and offset of the engineering pipes 11 in subsequent operations. The two inclined surfaces of the V-shaped support groove are symmetrically distributed. When it contacts the surface of the engineering pipe 11, regardless of the pipe diameter, its center line will automatically fall on the angle bisector of the V-shaped groove. Moreover, when the pipe is in an inclined state, one end of the V-shaped support bar can always contact the surface of the pipe. This natural geometric characteristic enables the V-shaped support to achieve automatic centering, fixation and single-point support without the need for complex additional positioning mechanisms, which greatly improves the accuracy of assembly and processing. Moreover, the V-shaped support can form a symmetrical constraint on the pipe through two inclined surfaces, which can effectively limit the radial movement and rotation of the pipe around the axis. With the upper and lower clamping devices, the pipe can be positioned and clamped from four directions to ensure that the clamping force is evenly distributed and to avoid deformation or damage to the pipe due to uneven force. At the same time, the V-shaped support can reduce the contact area between the pipe and the support while firmly positioning the pipe, thereby effectively reducing the wear of the anti-corrosion layer on the pipe surface.
