Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and more particularly, to an auxiliary welding device for circular pipes. Background Art

[0002] At present, for the welding operation of large-diameter circular pipes, the conventional method is to use a hoisting device to lift and place the large-diameter circular pipe on a roller rack to create the basic conditions for subsequent welding operations. However, due to the large weight of the large-diameter circular pipe, during the hoisting and transfer process, it is inevitably affected by factors such as the pulling force of gravity and uneven stress, resulting in the expansion of the initially formed weld. As the weld becomes larger, the originally precise circular structure of the circular pipe is damaged and no longer maintains its standard circular contour.

[0003] This problem of circular pipe deformation caused by hoisting will trigger a series of chain reactions in subsequent processing procedures. For example, during subsequent pipe fittings connection, assembly, and fine processing, due to the deviation of the circular pipe shape, additional adjustment and correction procedures are required to make up for it, which will undoubtedly consume more human, material, and time resources.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0052] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific embodiments of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, further technical solutions can be understood. Among some figures, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0053] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0054] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0055] Referring to Figures 1 to 3 , which is the first embodiment of the present invention, a circular pipe auxiliary welding device is proposed, including: a support frame 1 for being arranged on the ground, the support frame 1 having a support gap 11 for supporting the circular pipe; a welding piece 2 is movably arranged on the ground, and after the welding piece 2 moves, it is used for welding the circular pipe; one end of an inclined plate 3 is arranged on the ground, and the other end is placed on the support frame 1, and the circular pipe enters the support gap 11 through the inclined plate 3; a pushing piece 4 is movably arranged on the support frame 1, and the pushing piece 4 is used for pushing the circular pipe out of the support gap 11.

[0056] In this embodiment, the support frame 1 is placed on the workshop floor to ensure its stability. The support gap 11 is used to place the round tube. The welding part 2 is installed on the ground through a track or other moving guiding devices so that it can move freely in the horizontal direction to perform welding operations on the round tube in the support gap 11. One end of the inclined plate 3 is fixed at a suitable position on the ground, and the other end is placed on the support frame 1. The inclination angle of the inclined plate 3 should ensure that the round tube can smoothly roll into and out of the support gap 11 of the support frame 1 along the inclined plate 3 under the action of gravity. A telescopic cylinder can be used to drive a push plate to push the large round tube into the support gap 11 through the inclined plate 3. The pusher 4 is installed on the support frame 1 and can move linearly along the support frame 1 under the drive of a power device (such as a cylinder, a lead screw nut mechanism, etc.). After welding is completed, the pusher 4 acts to push the round tube out of the support gap 11, and the round tube rolls down to the ground along the inclined plate 3. When pushing the round tube into the support gap 11 again, the pusher 4 can support the round tube to prevent the round tube bracket from falling in the support gap 11.

[0057] The support gap 11 of the support frame 1 can provide a stable support basis for welding, ensure that the position of the round tube remains unchanged during the welding process, and improve the welding accuracy. The setting of the inclined plate 3 facilitates the feeding operation of the round tube. There is no need to use a hoisting piece to hoist the round tube onto the support frame 1, which not only prevents the expansion of the round tube weld, but also saves manpower and improves the feeding speed. The pusher 4 facilitates the discharging of the round tube after welding, making the entire welding process more automated, reducing manual intervention, improving production efficiency and reducing labor intensity. The pusher 4 and the inclined plate 3 are used in combination. During feeding, the pusher 4 supports the round tube to make the round tube stably enter the support gap 11.

[0058] Further, the mounting seat 12 is used to be set on the ground; the first L-shaped frame 13 is rotatably arranged on the mounting seat 12; the second L-shaped frame 14 is rotatably arranged on the mounting seat 12; there are four first rollers 15, and the four first rollers 15 are respectively rotatably arranged in pairs on the first L-shaped frame 13 and the second L-shaped frame 14, and the four first rollers 15 form the support gap 11.

[0059] In this embodiment, first, the mounting seat 12 is fixed on the ground to ensure its levelness and stability. The right-angle end of the first L-shaped frame is installed on the mounting seat 12 through a rotating shaft so that it can rotate around the shaft, and a first roller 15 is installed at each of the other two ends of the first L-shaped frame. Similarly, the right-angle end of the second L-shaped frame is also installed on the mounting seat 12 through another rotating shaft, and the other two first rollers 15 are correspondingly installed at the other two ends of the second L-shaped frame. The positional relationship of the four first rollers 15 enables them to jointly enclose a circular support gap 11 where the round tube can be placed and roll on the rollers.

[0060] The rotational settings of the first L-shaped frame and the second L-shaped frame enable the support frame 1 to adapt to round tubes of different diameters. By adjusting the relative angle between the two, the size of the support gap 11 can be changed, improving the compatibility of the device with round tubes of different specifications. The setting of the first roller 15 reduces the friction when the round tube moves within the support gap 11, enabling the round tube to rotate, which is beneficial for adjusting the position of the round tube during the welding process. At the same time, it also reduces the wear on the surface of the round tube and improves the product quality.

[0061] Furthermore, the first rotating shaft 5 is rotatably arranged on the mounting seat 12, the first L-shaped frame 13 is arranged on the first rotating shaft 5, and the first L-shaped frame 13 is rotatably arranged on the mounting seat 12 through the first rotating shaft 5; the second rotating shaft 6 is rotatably arranged on the mounting seat 12, the second L-shaped frame 14 is arranged on the second rotating shaft 6, and the second L-shaped frame 14 is rotatably arranged on the mounting seat 12 through the second rotating shaft 6; the transmission member 7 is arranged on the mounting seat 12. After the first rotating shaft 5 rotates, it drives the second rotating shaft 6 to rotate through the transmission member 7.

[0062] In this embodiment, the first rotating shaft 5 and the second rotating shaft 6 are installed on the mounting seat 12 to ensure that they can freely rotate around their own axes. The first L-shaped frame is fixed on the first rotating shaft 5, and the second L-shaped frame is fixed on the second rotating shaft 6. The transmission member 7 can adopt methods such as gear transmission, chain transmission, or belt transmission. For example, when using gear transmission, meshing gears are respectively installed on the first rotating shaft 5 and the second rotating shaft 6. When the first rotating shaft 5 rotates driven by a motor or other power source, the second rotating shaft 6 is driven to rotate synchronously through gear meshing; if using chain transmission, corresponding sprockets are installed on the first rotating shaft 5 and the second rotating shaft 6, and the chain is wound around the two sprockets. When the first rotating shaft 5 rotates, the chain drives the second rotating shaft 6 to rotate.

[0063] The linkage between the first rotating shaft 5 and the second rotating shaft 6 is achieved through the transmission member 7, enabling the first L-shaped frame and the second L-shaped frame to synchronously adjust the angle, ensuring the symmetry and stability of the support gap 11 during the adjustment process, which is beneficial for the precise positioning and stable support of the round tube. This linkage design simplifies the operation process. By only controlling the rotation of one rotating shaft, the adjustment of the entire support frame 1 can be achieved, improving the operation convenience and automation level of the device.

[0064] Furthermore, the other end of the inclined plate 3 is used to be placed on the second L-shaped frame 14, the first bevel gear 8 is chain-driven and arranged on the first rotating shaft 5; the third rotating shaft 9 is rotatably arranged on the mounting seat 12; the second bevel gear 10 is arranged at one end of the third rotating shaft 9, and the first bevel gear 8 and the second bevel gear 10 are meshed; the sliding frame 41 is slidably arranged on the mounting seat 12, and the sliding frame 41 is threaded on the other end of the third rotating shaft 9; the abutting member 42 is rotatably and swingably arranged on the sliding frame 41, and the abutting member 42 is used to abut against the round tube within the support gap 11.

[0065] In this embodiment, the first bevel gear 8 is installed at a suitable position on the first rotating shaft 5. The third rotating shaft 9 is installed on the mounting seat 12 through bearings, and a second bevel gear 10 meshing with the first bevel gear 8 is installed at one end of the third rotating shaft 9. The sliding frame 41 is installed on the mounting seat 12 through a guide rail or a chute, enabling it to slide linearly on the mounting seat 12. A thread is machined at the other end of the third rotating shaft 9, and a threaded hole matching it is provided on the sliding frame 41. The sliding frame 41 is threadedly connected to the third rotating shaft 9. After the round tube is welded, the driving member drives the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the first bevel gear 8 to rotate, and the first bevel gear 8 drives the second bevel gear 10 to rotate. After the second bevel gear 10 rotates, the sliding frame 41 drives the abutting member 42 to approach the round tube, pushing the round tube so that the round tube is completely located on the second L-shaped frame 14. As the pushing member 4 pushes and continues to rotate with the second L-shaped frame 14, the round tube enters the inclined plate 3 and slides down along the inclined plate 3, realizing automatic blanking. The swing frame 43 of the abutting member 42 is installed on the sliding frame 41 by means of a pin shaft or the like, enabling it to swing within a certain range. Two second rollers 44 are installed on the swing frame 43. When the sliding frame 41 moves under the drive of the second bevel gear 10, the abutting member 42 can approach or move away from the round tube in the support gap 11, and contacts the round tube through the rollers and applies a thrust or a pulling force.

[0066] By using the meshing transmission of the first bevel gear 8 and the second bevel gear 10, the rotational motion of the first rotating shaft 5 is converted into the rotational motion of the third rotating shaft 9, and then the linear movement of the sliding frame 41 is driven, realizing the power transmission and motion conversion between the pushing member 4 and the adjusting mechanism of the support frame 1, saving an additional power source and making the device structure more compact. When the angle of the round tube needs to be adjusted separately during the welding process, the first bevel gear 8 can be designed as a structure that slides on the first rotating shaft 5, enabling manual sliding of the first bevel gear 8 so that the first bevel gear 8 and the second bevel gear 10 are no longer meshed.

[0067] Furthermore, the swing frame 43 is swingably arranged on the sliding frame 41; there are two second rollers 44, and the two second rollers 44 are rotatably arranged on the swing frame 43. The second rollers 44 are used to abut against the round tube.

[0068] In this embodiment, a suitable shaft hole or shaft seat is provided on the sliding frame 41. The swing frame 43 is an L-shaped frame, and the right-angle end of the swing frame 43 is installed therein through a pin shaft, enabling the swing frame 43 to swing around the pin shaft by a certain angle. Two second rollers 44 are installed at the other two ends of the swing frame 43. The second rollers 44 are installed on the swing frame 43 through bearings to ensure that the second rollers 44 can rotate freely. After the second rollers 44 rotate, they can abut against both sides of the round tube to a greater extent.

[0069] The swinging design of the swinging frame 43 enables the abutting member 42 to better adapt to different positions of the circular tube within the support gap 11. Even if the circular tube has a certain eccentricity or inclination, the abutting position can be automatically adjusted through the swinging of the swinging frame 43, ensuring the effectiveness of the pushing. The arrangement of the two second rollers 44 further reduces the friction with the circular tube, improves the pushing efficiency, and also reduces the impact on the surface quality of the circular tube.

[0070] Furthermore, the fourth rotating shaft 110 is rotatably arranged on the second L-shaped frame 14, and the first roller 15 is rotatably arranged on the fourth rotating shaft 110; the first chain 120 is circulated and conveyed on the second rotating shaft 6 and the fourth rotating shaft 110.

[0071] In this embodiment, the fourth rotating shaft 110 is installed on the second L-shaped frame so that it can rotate around its own axis, and the first roller 15 is installed on the fourth rotating shaft 110 through a bearing. Sprockets are respectively installed on the second rotating shaft 6 and the fourth rotating shaft 110, and the first chain 120 is wound around these two sprockets to ensure that the first chain 120 is properly tensioned. When the second rotating shaft 6 rotates, the fourth rotating shaft 110 is driven to rotate synchronously through the first chain 120. This transmission method has a simple structure, high reliability, is easy to maintain and adjust, and reduces the operation cost of the device.

[0072] Furthermore, one end of the inclined plate 3 is slidably arranged on the ground, and the other end of the inclined plate 3 has a mounting portion 31. The mounting portion 31 is arranged on the fourth rotating shaft 110, and the inclined plate 3 is tangent to the first roller 15 concentric with the mounting portion 31.

[0073] In this embodiment, a guide rail or a chute is arranged on the ground, and one end of the inclined plate 3 is installed on it through a slider so that it can perform linear sliding on the ground to adjust the inclination angle and position of the inclined plate 3. A mounting portion 31 is designed at the other end of the inclined plate 3, and the mounting portion 31 is connected to the fourth rotating shaft 110 through a key connection or other fixing means, and it is ensured that the inclined plate 3 is tangent to the outer circumference of the first roller 15 concentric with the mounting portion 31. When loading and unloading, after the first L-shaped frame 13 and the second L-shaped frame 14 rotate, the inclined plate 3 is driven to swing. After the inclined plate 3 swings, it becomes more inclined, and the loading and unloading of the circular tube are more convenient, and the drop of the circular tube is smaller. In this way, when the circular tube rolls from the inclined plate 3 onto the first roller 15, it can make a smooth transition and reduce the impact.

[0074] The sliding arrangement at one end of the inclined plate 3 increases the adjustability of the inclined plate 3, and can flexibly adjust the feeding height and angle of the circular tube according to actual production requirements. The tangency design of the inclined plate 3 and the first roller 15 ensures the smoothness of the circular tube feeding process, avoids surface damage or position deviation of the circular tube caused by collision or jamming during feeding, and improves the feeding accuracy and reliability.

[0075] Further, the second chain 130 is circulated and conveyed on the inclined plate 3; the moving plate 140 is arranged on the second chain 130. The moving plate 140 is moved and arranged on the inclined plate 3 through the second chain 130. After the moving plate 140 moves to one end of the inclined plate 3, it is arranged parallel to the ground. After the moving plate 140 moves to the other end of the inclined plate 3, it is arranged perpendicular to the inclined plate 3.

[0076] In this embodiment, sprockets are installed on both sides of the inclined plate 3, and the second chain 130 is wound around the sprockets to form a circulating conveying structure, and the moving plate 140 is fixed on the second chain 130. When the second chain 130 rotates driven by a motor or other power source, the moving plate 140 moves on the inclined plate 3 along with the chain. By controlling the movement direction and speed of the chain, the moving plate 140 is in a horizontal state when it reaches one end of the inclined plate 3, facilitating the placement of the round tube thereon. When the moving plate 140 moves to the other end of the inclined plate 3, it automatically flips to a state perpendicular to the inclined plate 3, and the round tube is introduced onto the first roller 15 in the support gap 11.

[0077] The design of the circulating movement of the moving plate 140 on the inclined plate 3 realizes the automatic feeding function of the round tube, eliminating the need for manual placement of the round tubes onto the inclined plate 3 one by one, improving the feeding efficiency and reducing the labor intensity. The conversion of the different postures of the moving plate 140 at both ends of the inclined plate 3 ensures the stability of the round tube during the feeding process, avoiding the phenomenon of slipping or jamming when the round tube rolls on the inclined plate 3, and improving the safety and reliability of the production process.

[0078] Further, the third chain 150 is circulated and conveyed on the fourth rotating shaft 110 and the other end of the inclined plate 3, and the third chain 150 drives the first chain 120 and the second chain 130 to move synchronously.

[0079] In this embodiment, sprockets are respectively installed on the fourth rotating shaft 110 and the other end of the inclined plate 3, the third chain 150 is wound around these two sprockets, and the third chain 150 is connected to the first chain 120 and the second chain 130 through a chain connector, enabling them to work together. When the round tube is welded, only the angle of the round tube is adjusted, and the round tube will not be accidentally unloaded. In this embodiment, the first chain 120 can be removed, and after the welding is completed, the first chain 120 is reinstalled manually. When it rotates driven by the power of the first chain 120, it drives the third chain 150 and the second chain 130 to rotate synchronously, realizing the rotation of the first roller 15 on the support frame 1, the movement of the moving plate 140 on the inclined plate 3, and the orderly transmission and processing of the round tube within the entire device.

[0080] The setting of the third chain 150 realizes the linkage control of multiple key components in the whole device, enables the movements of various components to be coordinated, and improves the overall operation stability and reliability of the device. Driving the movements of multiple components through a power chain simplifies the structure of the power system of the device, reduces the equipment cost and maintenance difficulty, and also facilitates the automatic control and programming operation of the whole welding device.

[0081] Referring to Figures 4 to 5 , for the first embodiment of the present invention, further, the frame 170 is arranged to be lifted and lowered on the base 160, and the welding part 2 is slidably arranged on the frame 170.

[0082] In this embodiment, the base 160 is fixed on the workshop floor by means of anchor bolts or the like. A lifting mechanism, such as a screw jack or a hydraulic lift, is installed on the base 160. The frame 170 is installed on the moving end of the lifting mechanism, and the up-and-down movement of the frame 170 is realized through the action of the lifting mechanism. Guide rails or slide rails are installed on the frame 170, and the welding part 2 is installed on the frame 170 through sliders, so that the welding part 2 can slide in the horizontal direction on the frame 170, and welding equipment such as a welding power source and a welding torch is installed on the welding part 2.

[0083] The lifting setting of the frame 170 enables the welding part 2 to adapt to the welding requirements of round tubes with different diameters and heights. By adjusting the height of the frame 170, the welding torch of the welding part 2 can be in the best welding position. The sliding design of the welding part 2 on the frame 170 further expands the working range of the welding part 2, enabling it to perform welding operations in the axial direction of the round tube, realizing the all-round welding of the round tube, and improving the welding quality and efficiency.

[0084] Working process:

[0085] After the round tube is bent into a cylindrical shape, the round tube is pushed onto the moving plate 140 in a horizontal state. At this time, the two first rollers 15 on the first L-shaped plate face the round tube. As the driving member drives the first L-shaped frame 13 and the second L-shaped frame 14 to rotate, through the combined action of the transmission member 7, the first chain 120, and the third chain 150, the second chain 130 is driven to move. After the second chain 130 moves, it first drives the moving plate 140 to swing. After swinging, it ensures that the round tube is stuck between the moving plate 140 and the inclined plate 3. The second chain 130 continues to move, driving the moving plate 140 to rise along the inclined plate 3. With the action of the first chain 120, the inclination angle of the inclined plate 3 is gradually increasing. After the moving plate 140 drives the round tube to move to the other end of the inclined plate 3, the round tube is completely supported on the second L-shaped plate. At this time, the second roller 44 of the abutting member 42 just contacts the round tube. As the driving member continues to drive, the second roller 44 acts on the round tube, causing the round tube to be slowly clamped in the support gap 11 until the second roller 44 disengages from the round tube, and the round tube is clamped in the support gap 11. After the welding is completed, the driving member drives the first rotating shaft 5 to rotate, the first bevel gear 8 drives the second bevel gear 10 to rotate, and the sliding frame 41 drives the second roller 44 on the swinging plate to approach the round tube. After the first rotating shaft 5 continues to rotate, the second rotating shaft 6 is driven to rotate through the transmission member 7. The first L-shaped frame 13 and the second L-shaped frame 14 lift the round tube together. After lifting to the highest position, the second roller 44 contacts the round tube and pushes the round tube towards the second L-shaped plate, pushing the round tube onto the second L-shaped plate. Since the round tube is relatively heavy, in order to ensure that the round tube can roll down the inclined plate 3 smoothly, in this solution, a telescopic cylinder and a support plate can be designed on the mounting seat 12. After the first L-shaped frame 13 and the second L-shaped frame 14 lift the round tube to the highest position together, when the telescopic cylinder extends, it drives the support plate to lift the round tube, facilitating the second roller 44 to push the round tube along the direction of the second L-shaped plate. As the first L-shaped plate and the second L-shaped plate continue to rotate, the round tube is guided by the second L-shaped plate and rolls onto the inclined plate 3. The moving plate 140 drives the round tube to slowly roll to the ground.
