Description

Technical Field

[0001] The invention belongs to the technical field of metal processing, and in particular relates to an auxiliary welding device for a steel round pipe of a wind power conduit rack. Background Art

[0002] During the construction and maintenance of wind turbine conduit racks, metal pipes as key structural components often need to work under harsh environmental conditions. For example, erosion by natural factors such as wind and rain can cause cracks in the metal pipes, so they need to be repaired by welding.

[0003] In addition, when cracks appear in the metal pipe due to the external forces of wind and rain corrosion, the structural strength of the metal pipe at the crack will be weakened under the action of external forces such as wind, and it will bend to either side. At this time, when the existing welding device directly welds and repairs the cracks, the pressure on the welding area in the bending direction is significantly higher than that on other areas, resulting in the welding part being broken again due to pressure concentration in later use, seriously affecting the repair quality and service life. In addition, when the temperature drops, water vapor in the air condenses on the surface of the metal pipe, resulting in the arc and high temperature generated by welding during the welding process, causing the water condensed on the surface of the metal pipe to be electrolyzed and gasified, thereby forming a large number of pores and cracks at the welding part, further weakening the welding quality. In addition, during welding, the welding liquid is in direct contact with the low-temperature metal pipe, and is easy to solidify quickly, resulting in greater internal stress in the welding area, reducing the strength of the weld, and even causing degradation of material properties.

[0006] Preferably, the extrusion mechanism comprises a plurality of connecting blocks, and the plurality of connecting blocks are fixedly mounted on the outer side surface of the mounting seat at equal intervals around the circumference, and a limiting plate is fixedly mounted on the side of two adjacent upper and lower connecting blocks away from the mounting seat, a first swivel seat is fixedly mounted on the upper part of the outer curved surface of the limiting plate, a pressure rod is movably sleeved on the middle part of the first swivel seat, the pressure rod is in sliding contact with a guide block, a pull rod is movably sleeved on the bottom end of the pressure rod, a second swivel seat is movably sleeved on the bottom end of the pull rod, a plurality of second swivel seats are fixedly mounted on the inner curved surfaces with a ring, the ring is slidably sleeved on the outer curved surfaces of the plurality of limiting plates, and two third swivel seats are symmetrically fixedly mounted on the bottom surface of the ring, a pressure handle is movably sleeved on the middle part of the two third swivel seats, an end of the pressure handle close to the bottom mounting seat is movably sleeved on a fourth swivel seat, and the fourth swivel seat is fixedly mounted on the bottom surface of the bottom mounting seat.

[0007] Preferably, the mounting seat includes two half seats, the two half seats are symmetrically arranged, the mounting seat is formed by merging the two half seats, the outer curved surfaces of the two half seats are symmetrically fixed with two threaded blocks, and the middle parts of the two threaded blocks on the same side are threadedly connected with fixing screws.

[0008] Preferably, the collar comprises two half rings, the two half rings are symmetrically arranged, the collar is formed by merging the two half rings, and a connecting sleeve is slidably sleeved at the connection between the two half rings.

[0009] Preferably, the dehumidification mechanism includes a heating chamber, which is fixedly mounted on the upper surface of the upper half seat, and elastic rings are fixedly mounted on the upper and lower parts of the inner cavity of the heating chamber away from the metal tube, and a plurality of heat conducting plates are fixedly mounted at equal intervals on the circumference of two elastic rings close to the metal tube, the heat conducting plates are slidably sleeved with the heating chamber, and the heat conducting plates are in sliding contact with the circular tube, a top cover is fixedly sleeved on the upper part of the inner cavity of the heating chamber away from the metal tube, and a rubber sleeve is fixedly mounted on the top end of the heating chamber close to the metal tube.

[0010] Preferably, the limiting plate is made of a hard material, and the distance from the end of the pressing handle away from the metal tube to the third rotating seat is greater than the distance from the connection between the pressing handle and the fourth rotating seat to the third rotating seat.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention presses the pressing handle downward away from one end of the metal tube, so that the pressing block drives the multiple reinforcing plates to move synchronously in the direction of the metal tube, and the center lines of the multiple reinforcing plates remain unchanged. At this time, when the upper part of the gap to be welded in the metal tube is bent and tilted relative to the lower part of the gap to be welded in the metal tube, the multiple reinforcing plates use the lower part of the gap to be welded in the metal tube as a reference, and the reinforcing plates correct the upper part of the gap to be welded in the metal tube so that the upper part of the gap to be welded in the metal tube coincides with the center line of the lower part of the gap to be welded in the metal tube. Otherwise, the lower part of the gap to be welded in the metal tube is corrected, thereby solving the problem that when the metal tube has cracks under the external force of wind and rain corrosion, the structural strength of the metal tube at the crack is weakened and bending occurs. At this time, after the crack is directly welded, the pressure on the welding part in the bending direction of the metal tube is always greater than that on other areas, resulting in the problem that the metal tube is easy to break in the later stage.

[0013] 2. In addition, when the center line of the upper part of the metal tube's welding gap is aligned with the center line of the lower part of the metal tube's welding gap, the reinforcing plate and the metal tube are welded together along the middle of the two adjacent reinforcing plates, so as to realize the circumferential equidistant fixed welding of multiple reinforcing plates at the metal tube welding point. At this time, the tensile strength of the metal tube welding point is increased by the high-strength reinforcing plate, so that it can withstand greater tensile force, and at the same time, the bending and twisting resistance of the metal tube welding point is improved, and its structural stability is improved, so as to overcome the problem of bending and breaking of the metal tube at the welding point due to insufficient strength.

[0014] 3. The mounting seat of the present invention drives the rubber sleeve on the dehumidification mechanism to fit closely with the curved surface of the metal pipe. When the metal pipe is in a vertical state and the surface is attached with water droplets condensed in the air, the metal pipe is knocked at this time. The water droplets attached to the surface of the metal pipe slide downward along the outer curved surface of the metal pipe under the action of the vibration of the metal pipe, and flow to the inner cavity of the heating chamber through the upper surface of the rubber sleeve, and react with the quicklime in the inner cavity of the heating chamber to generate heat. The generated heat is transferred to the surface of the metal pipe through the heat conduction plate to heat the metal pipe, so that the moisture at the welding point of the metal pipe is completely evaporated, and at the same time, the problem of moisture in the air condensing at the welding point again is avoided, and when welding the metal pipe, the arc and high temperature generated by welding cause the electrolysis and gasification of moisture condensed at the welding point of the metal pipe, resulting in a large number of pores or cracks at the welding point. At the same time, by preheating the welding point in advance, the welding liquid is prevented from contacting the low-temperature metal pipe and solidifying quickly, causing the welding point, the internal stress is increased, and the strength is reduced. At the same time, it is avoided to carry a heavy heating device and an alignment device when welding at high altitude, which is convenient for efficient operation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 5 As shown, an embodiment of the present invention provides an auxiliary welding device for a steel round pipe of a wind power conduit frame, comprising a metal pipe 1, wherein a mounting seat 2 is symmetrically fixedly arranged on the upper and lower sides of the metal pipe 1, wherein the mounting seat 2 comprises two half seats 201, wherein the two half seats 201 are symmetrically arranged, and the mounting seat 2 is formed by merging the two half seats 201, wherein two threaded blocks 202 are symmetrically fixedly arranged on the outer curved surfaces of the two half seats 201, wherein the middle parts of the two threaded blocks 202 on the same side are threadedly connected with fixing screws 203, and a plurality of guide grooves are fixedly opened on the upper surface of the mounting seat 2 at equal intervals, wherein the plurality of guide grooves are fixedly opened on the upper surface of the mounting seat 2 at equal intervals, and the plurality of guide grooves are fixedly opened on the upper surface of the mounting seat 2 at equal intervals. The middle part of each of the metal tubes 1 is slidably sleeved with a pressing block 3, which is made of a magnetic material and a magnet, so that the pressing block 3 can adsorb the reinforcing plate 10 on its inner side, which is convenient for installing and unloading the reinforcing plate 10. At the same time, according to the metal tubes 1 with different outer diameters, the reinforcing plates 10 with different curvatures of the inner curved surfaces can be replaced, so that the reinforcing plates 10 are closely attached to the outer curved surfaces of the metal tubes 1, and the local pressure between the reinforcing plates 10 and the metal tubes 1 is reduced, so as to avoid the reinforcing plates 10 from crushing the surface of the metal tubes 1, and at the same time, multiple reinforcing plates 10 can clamp the metal tubes 1 with different diameters; Among them, the pressing block 3 moves in the horizontal direction, and the side of the multiple guide grooves away from the metal tube 1 is slidably sleeved with a push block 4, and the push block 4 moves in the vertical direction. The push block 4 is in sliding contact with the pressing block 3, and the contact surface between the push block 4 and the pressing block 3 is an inclined surface, so that when the push block 4 moves toward the pressing block 3 in sliding contact with it, the push block 4 pushes the pressing block 3 to move in the direction of the metal tube 1, and the pressing block 3 pushes the reinforcing plate 10 to clamp the metal tube 1, and at the same time reduces the friction resistance between the push block 4 and the pressing block 3, thereby reducing the subsequent force required to press the pressing handle 809 downward away from one end of the metal tube 1, which is convenient for subsequent manual operation. The middle part of the push block 4 is slidably sleeved with a curved rod 5, and the adjacent ends of the upper and lower adjacent curved rods 5 are movably sleeved with a movable seat 6. The side of the movable seat 6 away from the metal tube 1 is fixedly installed with a guide block 7, and an extrusion mechanism 8 is provided between the movable seat 6 and the upper and lower mounting seats 2; like Figure 1 and Figure 2 As shown, the extrusion mechanism 8 includes a plurality of connecting blocks 801, and the plurality of connecting blocks 801 are fixedly installed on the outer side surface of the mounting seat 2 at equal intervals around the circumference. A limiting plate 802 is fixedly installed on the side of the adjacent upper and lower connecting blocks 801 away from the mounting seat 2. The limiting plate 802 is made of a hard material, and the limiting plate 802 is made of high carbon steel, so as to avoid that when the mounting seat 2 extrude and correct the upper part of the gap to be welded in the metal tube 1 and the lower part of the gap to be welded in the metal tube 1 through the push block 4, the pressure block 3 and the reinforcing plate 10, the limiting plate 802 is bent due to insufficient hardness, resulting in the misalignment of the upper and lower mounting seats 2, resulting in the inability to accurately connect the center lines of the upper part of the gap to be welded in the metal tube 1 and the lower part of the gap to be welded in the metal tube 1, resulting in a reduction in the strength of the subsequent welding of the metal tube 1; Among them, a first rotating seat 803 is fixedly installed on the upper part of the outer curved surface of the limiting plate 802, a pressure rod 804 is movably sleeved in the middle part of the first rotating seat 803, the pressure rod 804 is in sliding contact with the guide block 7, the bottom end of the pressure rod 804 is movably sleeved with a pull rod 805, the bottom end of the pull rod 805 is movably sleeved with a second rotating seat 806, the inner curved surfaces of the plurality of second rotating seats 806 are fixedly installed with a collar 807, the collar 807 is slidably sleeved with the outer curved surfaces of the plurality of limiting plates 802, two third rotating seats 808 are symmetrically fixedly installed on the bottom surface of the collar 807, a pressure handle 809 is movably sleeved in the middle part of the two third rotating seats 808, one end of the pressure handle 809 close to the bottom mounting seat 2 is movably sleeved with a fourth rotating seat 810, and the distance from the end of the pressure handle 809 away from the metal pipe 1 to the third rotating seat 808 is greater than the pressure handle 809 The distance from the connection point of the fourth rotating seat 810 to the third rotating seat 808 is reduced by pressing the pressure handle 809 downward away from one end of the metal tube 1, and the force used to drive the push block 4 to extrude and correct the upper part of the gap to be welded in the metal tube 1 and the lower part of the gap to be welded in the metal tube 1 through the pressure block 3 and the reinforcing plate 10. It is achieved that the upper part of the gap to be welded in the metal tube 1 and the lower part of the gap to be welded in the metal tube 1 can be driven by manpower to extrude and correct the upper part of the gap to be welded in the metal tube 1, avoiding the need to carry large-volume industrial correction equipment during high-altitude welding operations. The fourth rotating seat 810 is fixedly installed on the bottom surface of the bottom mounting seat 2, and the upper surface of the upper mounting seat 2 is symmetrically fixedly installed with a dehumidification mechanism 9. The inner side surfaces of the two adjacent pressure blocks 3 are adsorbed with reinforcing plates 10, and the metal tube 1 is clamped in the middle of multiple reinforcing plates 10.

[0019] like Figure 1 and Figure 2 As shown, the collar 807 includes two half rings 8071, and the two half rings 8071 are symmetrically arranged. The collar 807 is composed of two half rings 8071 combined together. The connection between the two half rings 8071 is slidably sleeved with a connecting sleeve 8072, so that after sliding the connecting sleeve 8072 to either side, the two half rings 8071 can be separated or merged together with the two half seats 201, which is convenient for installation and disassembly of the welding device.

[0020] like Figure 1 and Figure 4As shown, the dehumidification mechanism 9 includes a heating chamber 901, and the heating chamber 901 is fixedly mounted on the upper surface of the upper half seat 201. The inner cavity of the heating chamber 901 is provided with a chemical powder that generates a large amount of heat when reacting with water. The chemical powder can be quicklime, thereby reducing the welding cost and reducing the weight of the items carried during high-altitude operations, avoiding the need to carry heavy heating equipment that requires power supplies, etc., and the upper and lower parts of the inner cavity of the heating chamber 901 away from the metal pipe 1 are fixedly mounted with elastic rings 902, and a plurality of heat conducting plates 903 are fixedly mounted at equal intervals on the circumference of the two elastic rings 902 close to the metal pipe 1. The heat conducting plates 903 are made of heat conducting material, and the heat conducting plates 903 are made of copper alloy, thereby achieving rapid dehumidification of the heat conducting plates 903. The heat generated by the reaction of quicklime and water is transferred to the surface of the metal tube 1, so that the moisture in the welding area of ​​the metal tube 1 evaporates quickly, thereby improving the welding efficiency. The heat conducting plate 903 is slidably sleeved with the heating chamber 901, and the heat conducting plate 903 is in sliding contact with the round tube. The upper part of the inner cavity of the heating chamber 901 away from the metal tube 1 is fixedly sleeved with a top cover 904, and the top of the heating chamber 901 is fixedly installed on the side close to the metal tube 1. The rubber sleeve 905 is made of rubber material, and the rubber sleeve 905 is made of flexible rubber, so that when the two half seats 201 are merged, the rubber sleeve 905 can fit closely with the curved surface of the metal tube 1, so as to prevent water drops above the rubber sleeve 905 on the outer curved surface of the metal tube 1 from sliding to the welding area below.

[0021] Working principle: When the present invention is used, firstly, a plurality of reinforcing plates 10 are respectively placed on the inner curved surfaces of a plurality of groups of upper and lower adjacent pressing blocks 3, at which time the pressing blocks 3 adsorb the reinforcing plates 10 and fit closely therewith, then the metal tube 1 is sleeved on the middle of the plurality of reinforcing plates 10 through the left and right groups of half seats 201, and the gap of the metal tube 1 to be welded is disposed in the middle of the upper and lower groups of half seats 201, then the fixing screw 203 is rotated, and the fixing screw 203 merges the upper and lower groups of half seats 201 through the threaded block 202, so that the upper and lower groups of threaded blocks 202 form a mounting seat 2 with a complete structure, and at the same time, the connecting sleeve 8072 is moved to the junction of the two half rings 8071, so that the welding device can be quickly assembled at any position of the metal tube 1 to be welded, avoiding the need for the welding device to be moved from the bottom or top end of the metal tube 1 to the welding position, resulting in the problem of difficulty in installation and low efficiency of the welding device when the welding position is too far away from the top or bottom of the metal tube 1; When the welding device assembly is completed and the middle of the welding device is at the gap to be welded, press the pressure handle 809 downward away from one end of the metal tube 1. At this time, the pressure handle 809 pulls the third rotating seat 808 to move downward, the third rotating seat 808 pulls the ring 807 to move downward, the ring 807 pulls the second rotating seat 806 to move downward, the second rotating seat 806 pulls the pull rod 805 to move downward, the pull rod 805 pulls the bottom end of the pressure rod 804 to rotate in the direction of the metal tube 1, the pressure rod 804 presses the guide block 7 to move in the direction of the metal tube 1, the guide block 7 pushes the movable seat 6 to move in the direction of the metal tube 1, the movable seat 6 pushes the top end of the upper curved rod 5 to move upward, the bottom end of the lower curved rod 5 moves downward, the upper curved rod 5 pushes the sliding The push block 4 in dynamic contact moves upward, and the lower curved rod 5 pushes the push block 4 in sliding sleeve connection with it to slide downward, and the push block 4 pushes the pressing block 3 to move in the direction of the lower metal tube 1, and the pressing block 3 pushes the reinforcing plate 10 to move in the direction of the metal tube 1, so that the multiple reinforcing plates 10 move synchronously in the direction of the metal tube 1 while keeping the center lines of the multiple reinforcing plates 10 unchanged. At this time, when the upper part of the gap to be welded in the metal tube 1 is bent and tilted relative to the lower part of the gap to be welded in the metal tube 1, the multiple reinforcing plates 10 use the lower part of the gap to be welded in the metal tube 1 as a reference, and the reinforcing plates 10 correct the upper part of the gap to be welded in the metal tube 1, so that the upper part of the gap to be welded in the metal tube 1 coincides with the center line of the lower part of the gap to be welded in the metal tube 1; On the contrary, when the lower part of the gap to be welded in the metal tube 1 is bent and tilted relative to the upper part of the gap to be welded in the metal tube 1, the reinforcing plate 10 corrects the lower part of the gap to be welded in the metal tube 1, thereby solving the problem that when the metal tube 1 is cracked under the external force of wind and rain corrosion, the structural strength of the metal tube 1 at the crack is weakened and bending occurs. At this time, after the crack is directly welded, the pressure on the welding part of the bending direction of the metal tube 1 is always greater than that on other areas, which makes the metal tube 1 easy to break in the later stage. In addition, when the upper part of the gap to be welded in the metal tube 1 is welded with the After the center line of the lower part of the welding gap of the metal tube 1 is aligned, the reinforcing plate 10 and the metal tube 1 are welded together along the middle of two adjacent reinforcing plates 10, so that a plurality of reinforcing plates 10 are fixedly welded at the circumference of the metal tube 1 at equal intervals. At this time, the tensile strength of the welding part of the metal tube 1 is increased by the high-strength reinforcing plate 10, so that it can withstand greater tensile force, and at the same time, the bending and twisting resistance of the welding part of the metal tube 1 is improved, and its structural stability is improved, so as to overcome the problem that the metal tube 1 is bent and broken again at the welding part due to insufficient strength; At this time, when the fixing screw 203 of the present invention is rotated to merge the upper and lower half seats 201, the upper two half seats 201 drive the rubber sleeve 905 on the dehumidification mechanism 9 to fit tightly with the side of the metal tube 1, and at the same time, the elastic ring 902 pushes the heat conducting plate 903 to fit tightly with the curved surface of the metal tube 1. When the metal tube 1 is in a vertical state and the surface is attached with water droplets condensed in the air, the metal tube 1 is knocked at this time. The water droplets attached to the surface of the metal tube 1 slide downward along the outer curved surface of the metal tube 1 under the action of the vibration of the metal tube 1, and flow to the inner cavity of the heating chamber 901 through the upper surface of the rubber sleeve 905, and react with the quicklime in the inner cavity of the heating chamber 901 to generate heat. The heat generated The heat is transferred to the surface of the metal tube 1 through the heat conducting plate 903 to heat the metal tube 1, so that the moisture at the welding point of the metal tube 1 is completely evaporated, and the problem of moisture in the air condensing at the welding point again is avoided. When welding the metal tube 1, the arc and high temperature generated by welding cause the electrolysis and gasification of moisture condensed at the welding point of the metal tube 1, resulting in a large number of pores or cracks at the welding point. At the same time, by preheating the welding point in advance, the welding liquid is prevented from contacting with the low-temperature metal tube 1 and quickly solidifying, causing the internal stress of the welding point to increase and the strength to decrease. At the same time, the need to carry heavy heating devices and alignment devices during high-altitude welding is avoided, which facilitates efficient operation.
