Description

Technical Field

[0002] In the manufacture and installation of steel structures, steel pipes are an important component and are widely used in fields such as construction, bridges, towers, and machinery manufacturing. The welding quality of steel pipes is directly related to the safety and reliability of the entire steel structure. Patent CN219767273U (publication date: 2023-09-29) discloses that a fixed frame and a sliding frame are arranged on the welding table, and a rotating sleeve is arranged inside the fixed frame and the sliding frame. The rotating sleeve is stably rotated by using a roller inside the through-hole to cooperate with the rotating sleeve. Two arc-shaped clamping plates are arranged inside the rotating sleeve. The arc-shaped clamping plates are driven by a first electric push rod to clamp the steel pipe and fix the steel pipe in the middle of the rotating sleeve. The driving motor cooperates with the gear ring and the driving wheel gear to rotate the rotating sleeve, thereby enabling the two steel pipes to be rotated and welded during the welding process. This technical solution does not take into account the weight and rotational inertia of the steel pipe. This rotation will cause stress concentration at the joint of the steel pipe. Stress concentration will lead to a decrease in the strength of the welded joint and even cracks or deformation during the welding process. Especially in large steel structures, the diameter of the steel pipe is large, and the stress concentration generated during rotation is particularly obvious, seriously affecting the welding quality and the reliability of the structure.

[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] See also Figure 1-14 An embodiment of the present invention provides a steel structure forming and arranging welding device, comprising a rotating seat structure 3 disposed between two pipe sleeves 7. The ends of the steel pipes pass through the pipe sleeves 7 to the bottom of the rotating seat structure 3. The pipe sleeves 7 are used to fix steel pipes of different diameters. An adjustable clamping device is designed inside the pipe sleeves to accommodate steel pipes of various diameters. This design enables the device to be widely used for welding steel pipes of different specifications, improving the versatility and flexibility of the device. The rotating seat structure 3 is located between the two pipe sleeves 7 and provides a stable support platform for the welding operation. The device also includes: Two welding guns 8 are symmetrically arranged on the rotating base structure 3. The two welding guns 8 perform synchronous welding on the connection of the steel pipe from different positions. The welding guns 8 are symmetrically arranged on the rotating base structure 3. This design enables the welding guns 8 to rotate around the connection of the steel pipe for welding, while the steel pipe itself remains stationary. Through the rotation of the welding guns 8, the welding process is more uniform, avoiding the displacement or deformation of the steel pipe due to its own rotation, improving the welding quality and stability. At the same time, the synchronous welding design of the two welding guns 8 further improves the welding efficiency; The swivel structures 2 are symmetrically arranged on both sides of the rotating base structure 3. The swivel structures 2 drive the rotating base structure 3 to rotate. This design enables the welding gun 8 to perform a full range of welding operations around the joint of the steel pipe during the welding process, while the steel pipe itself remains stationary. This design of rotating the welding gun while the steel pipe remains stationary not only improves the flexibility and uniformity of welding, but also avoids the stress concentration problem that may be caused by the rotation of the steel pipe during welding, further improving the welding quality. Several telescopic clamping structures 1 are arranged in an annular array on the pipe sleeve 7. Several telescopic clamping structures 1 clamp the ends of the two steel pipes and push the two steel pipes toward the rotating seat structure 3 so that the two steel pipes contact each other. After the two steel pipes are squeezed, the telescopic clamping structure 1 stops pushing the steel pipes and continues to clamp the steel pipes. The telescopic clamping structure 1 is arranged in an annular array on the pipe sleeve 7. Its function is to clamp the ends of the two steel pipes and automatically push the two steel pipes toward the rotating seat structure 3 through a telescopic action so that the two steel pipes contact each other and are squeezed. This automatic approach design not only improves the efficiency of the preparation work before welding, but also ensures that the steel pipes can be tightly fitted before welding, providing good initial conditions for welding. When the steel pipes are squeezed, the telescopic clamping structure 1 stops pushing, but continues to clamp the steel pipe to prevent the steel pipe from displacement during the welding process, thereby ensuring the stability of the welding.

[0023] In the embodiments of the present invention, please refer to Figure 6-8 The telescopic clamping structure 1 includes a mounting seat 12 fixedly mounted on the outer wall of the pipe sleeve 7 in an annular array. This annular array installation method can ensure that the clamping structure is evenly distributed around the pipe sleeve 7, thereby uniformly clamping and pushing the steel pipe, improving the stability and reliability of the device. A double-piston-rod cylinder 11 is fixedly mounted on the side wall of the mounting seat 12 away from the pipe sleeve 7. The double-piston-rod cylinder 11 is a device widely used in the field. Its specific structure and working principle belong to the existing technology in this field and are not described in detail here. The double-piston-rod cylinder 11 serves as a power source and can provide stable thrust and pulling force to drive subsequent actions to realize the clamping and pushing functions of the steel pipe. Both ends of the piston rod of the double-piston-rod cylinder 11 are provided with a horizontal sliding structure 13 and a radial sliding structure 14, so that the thrust of the cylinder can be transmitted to two different structures through the piston rod, respectively realizing the horizontal pushing and radial clamping functions of the steel pipe, thereby improving the versatility and integration of the device.

[0024] The horizontal sliding structure 13 is arranged on the side of the radial sliding structure 14 away from the rotating seat structure 3. This layout enables the horizontal sliding structure 13 to directly act on the steel pipe, pushing the steel pipe to approach the rotating seat structure 3, while the radial sliding structure 14 is responsible for providing radial clamping force during the approach of the steel pipe to ensure the stability and accurate positioning of the steel pipe. The double-piston rod cylinder 11 drives the horizontal sliding structure 13 to slide through the piston rod. This sliding action can push the steel pipe from the initial position to the welding position, so that the ends of the two steel pipes are in close contact, creating good conditions for subsequent welding operations. The sliding horizontal sliding The structure 13 pushes the two steel pipes closer to each other. Through this pushing action, the two steel pipes can fit tightly before welding, ensuring the contact area and welding quality during welding, and radially squeezes the radial sliding structure 14. The squeezed radial sliding structure 14 clamps the steel pipe. After being squeezed by the horizontal sliding structure 13, the radial sliding structure 14 will generate a stable clamping force through its internal mechanical structure, firmly clamping the steel pipe in the pipe sleeve 7. This clamping method can not only adapt to steel pipes of different diameters, but also maintain the stability and accurate positioning of the steel pipe during the welding process, thereby ensuring the welding quality.

[0025] In the embodiments of the present invention, please refer to Figure 8 The horizontal sliding structure 13 includes a wedge-shaped seat 131, and two inclined sliding grooves are provided in the wedge-shaped seat 131. The sliding grooves are arranged so that one end close to the rotating seat structure 3 is away from the steel pipe and the other end away from the rotating seat structure 3 is close to the steel pipe. This inclined design enables the wedge-shaped seat 131 to produce a radial extrusion effect on the radial sliding structure 14 through the sliding groove when sliding horizontally, thereby realizing the clamping and pushing function of the steel pipe. The radial sliding structure 14 includes two sliding rods 142 that are clamped in the sliding groove. The two sliding rods 142 are fixedly installed with radial sliding sleeves 141 on one side close to the axis of the steel pipe. This structural design enables the sliding rods 142 to slide in the sliding groove and apply clamping force to the steel pipe through the radial sliding sleeves 141. The design of the radial sliding sleeves 141 can ensure that the clamping force is evenly distributed and adapts to steel pipes of different diameters. The double-piston rod cylinder 11 is connected to the The piston rod drives the two wedge-shaped seats 131 to slide in the direction close to the rotating seat structure 3. This horizontal sliding action is the core of the entire clamping and pushing process. Through the thrust provided by the cylinder double-piston rod cylinder 11, the wedge-shaped seat 131 can push the steel pipe from the initial position to the welding position, ensuring that the ends of the two steel pipes are in close contact. The sliding wedge-shaped seat 131 radially squeezes the slide rod 142 and the radial sleeve 141 through the slide groove. When the wedge-shaped seat 131 slides in the horizontal direction, the inclined slide groove inside it will produce a radial extrusion effect on the slide rod 142 and the radial sleeve 141. This extrusion effect causes the slide rod 142 to slide in the slide groove, and at the same time the radial sleeve 141 applies a clamping force to the steel pipe. This design not only realizes the automatic clamping of the steel pipe, but also can dynamically adjust the clamping force during the approach of the steel pipe, ensuring that the steel pipe remains stable during the welding process.

[0026] In the embodiments of the present invention, please refer to Figure 9 and Figure 10 , a gear rod 144 is provided on the side of the radial sleeve 141 close to the axis of the steel pipe, and a second return spring 146 is provided on the side of the gear rod 144 close to the radial sleeve 141. The second return spring 146 provides redundant sliding space for the gear rod 144 away from the steel pipe direction, and provides return power for the gear rod 144 after the steel pipe is taken out of the pipe sleeve 7. This design allows the gear rod 144 to have a certain sliding range when squeezed by the radial sleeve 141, avoiding excessive stress caused by the rigid connection. At the same time, when the steel pipe is taken out of the pipe sleeve 7, the second return spring 146 can provide return power for the gear rod 144 to return it to its initial position, facilitating the next clamping operation. The squeezed radial sleeve 141 radially squeezes the second return spring 146, and the second return spring 146 is pressed. The second return spring 146 radially squeezes the gear rod 144, causing the gear rod 144 to approach the steel pipe. The gear rod 144 clamps the steel pipe and drives the two steel pipes closer to each other under the push of the piston rod. When the radial sleeve 141 is squeezed by the horizontal sliding structure 13, the radial sleeve 141 will radially squeeze the second return spring 146. The second return spring 146 then transmits force to the gear rod 144, causing the gear rod 144 to approach the steel pipe. The approaching action of the gear rod 144 makes it contact with the steel pipe and exerts a clamping force, thereby firmly clamping the steel pipe. Under the push of the piston rod of the double-piston-rod cylinder 11, the horizontal sliding structure 13 continues to slide, and through the cooperation of the wedge seat 131 and the radial sleeve 141, the two steel pipes are driven closer to each other until the ends of the two steel pipes are in close contact.

[0027] When the two steel pipes contact each other, if the piston rod of the double-piston-rod cylinder 11 continues to push the wedge seat 131 to slide toward the rotating seat structure 3, the wedge seat 131 will continue to apply pressure to the gear rod 144 through the radial sleeve 141. Since the gear rod 144 and the radial sleeve 141 are not rigidly connected, but indirectly connected through the second return spring 146, the second return spring 146 will be further compressed. This compression provides redundancy for the sliding action, allowing the device to absorb excess thrust and prevent the two steel pipes from being deformed due to excessive extrusion. This design not only protects the structural integrity of the steel pipe, but also improves the reliability and durability of the welding device.

[0028] In the embodiments of the present invention, please refer to Figure 6-7The gear rod 144 is hinged to a swing block 145 on the side close to the steel pipe. This hinge design allows the swing block 145 to swing freely within a certain range, and a blocking column is provided on the side of the hinge point close to the rotating seat structure 3. The function of the blocking column is to limit the swing range of the swing block 145 and prevent it from swinging excessively, causing structural instability or damage. The design of the swing block 145 is asymmetric. The side close to the rotating seat structure 3 is longer, while the side away from the rotating seat structure 3 is shorter. This design allows the swing block 145 to naturally form a trumpet-shaped structure under the action of its own gravity. The opening direction of this trumpet-shaped structure Away from the rotating seat structure 3, that is, the opening of the horn is facing the direction of insertion of the steel pipe. This design can effectively guide the steel pipe to be smoothly inserted into the pipe sleeve 7, reduce the resistance and friction during the insertion of the steel pipe, and improve the convenience and efficiency of the device. Several swing blocks 145 guide the steel pipe inserted into the pipe sleeve 7. When the steel pipe is inserted, the long end of the swing block 145 can contact the steel pipe and swing appropriately under the push of the steel pipe, thereby guiding the steel pipe to smoothly enter the interior of the pipe sleeve 7. This guiding function not only improves the accuracy of steel pipe insertion, but also reduces the wear between the steel pipe and the pipe sleeve 7, and extends the service life of the device.

[0029] In the embodiments of the present invention, please refer to Figure 9-14 One end of the gear rod 144 is inserted into the interior of the radial sleeve 141, and the outer sliding sleeve of the radial sleeve 141 is provided with a horizontal sleeve 143, which is arranged to slide in the limiting groove opened in the side wall of the pipe sleeve 7. This design enables the gear rod 144 and the radial sleeve 141 to slide in the horizontal direction. At the same time, the sliding of the horizontal sleeve 143 in the limiting groove limits the movement range of the gear rod 144 and the radial sleeve 141, ensuring the stability and accuracy of its movement. The wedge seat 131 slides horizontally through the radial sleeve 141 to drive the horizontal sleeve 143 to slide horizontally. When the wedge seat 131 slides in the horizontal direction, it drives the horizontal sleeve 143 to slide horizontally in the limiting groove through the radial sleeve 141. This The linkage mechanism enables the movement of the wedge seat 131 to be transmitted to the gear rod 144, thereby realizing the clamping and pushing functions of the steel pipe. The transmission of horizontal sliding is completed through the cooperation of the radial sleeve 141 and the horizontal sleeve 143, ensuring the smoothness and reliability of the movement. A wedge-shaped buckle 135 is provided on the side of the horizontal sleeve 143 away from the rotating seat structure 3, and bevel teeth are provided on the side wall of the gear rod 144. The design of the bevel teeth enables the gear rod 144 to interact with the wedge-shaped buckle 135 when subjected to radial force, thereby realizing the positioning and fixing function of the gear rod 144. At this time, the wedge-shaped buckle 135 prevents the gear rod 144 from continuing to slide away from the steel pipe through the bevel teeth, and cooperates with the gear rod 144 approaching the steel pipe to perform secondary fixation on the steel pipe.

[0030] When the steel pipe is inserted into the pipe sleeve 7, the steel pipe will push the gear rod 144 to slide in the direction away from the steel pipe. The gear rod 144 will squeeze the second return spring 146 during the sliding process, thereby generating a certain clamping force. This preliminary clamping force can temporarily fix the steel pipe in the pipe sleeve 7 to prevent it from moving in subsequent operations. At this time, several gear rods 144 work together to perform preliminary clamping on the steel pipe. When the double-piston-rod cylinder 11 drives the wedge-shaped seat 131 to slide through the piston rod, the wedge-shaped buckle 135 will approach the helical teeth on the gear rod 144. As the wedge seat 131 continues to slide, the wedge-shaped buckle 135 will eventually be clamped on the side of the helical teeth away from the steel pipe. This clamping design makes the gear rod 144 When subjected to radial force, it can be firmly fixed to prevent it from continuing to slide away from the steel pipe. At this time, the wedge-shaped buckle 135 prevents the tooth rod 144 from continuing to slide away from the steel pipe through the bevel teeth, and cooperates with the tooth rod 144 approaching the steel pipe to perform secondary fixation on the steel pipe. When the wedge-shaped buckle 135 is clamped on the side of the bevel teeth away from the steel pipe, it will prevent the tooth rod 144 from continuing to slide away from the steel pipe. At this time, the tooth rod 144 approaches the steel pipe under the action of the second return spring 146, further increasing the clamping force, thereby achieving secondary fixation of the steel pipe. This secondary fixation design can ensure that the steel pipe remains stable during the welding process and prevent it from being displaced or shaken due to external force.

[0031] In the embodiments of the present invention, please refer to Figure 8 The wedge-shaped seat 131 is fixedly connected to a T-shaped plate 132 on the side away from the rotating seat structure 3. The side of the T-shaped plate 132 close to the steel pipe passes through the side wall of the pipe sleeve 7 and is fixedly connected to the first connecting plate 133. This structural design allows the movement of the wedge-shaped seat 131 to be transmitted to the first connecting plate 133 through the T-shaped plate 132, thereby realizing the linkage of the entire horizontal sliding structure 13. The first connecting plate 133 is provided with a second connecting plate 134 on the side close to the rotating seat structure 3. The second connecting plate 134 is set in the limiting groove of the pipe sleeve 7 to slide. The function of the limiting groove is to limit the second connecting plate The movement direction of the connecting plate 134 ensures that it slides smoothly in the horizontal direction. This design further improves the stability and reliability of the entire horizontal sliding structure 13. The first connecting plate 133 is inserted into the interior of the second connecting plate 134, and a first return spring 136 is provided between the second connecting plate 134 and the first connecting plate 133. The function of the first return spring 136 is to provide a certain elastic buffer during the horizontal sliding process to prevent structural damage due to excessive extrusion. This elastic buffer design can effectively absorb the impact force during the movement and protect the various components of the device.

[0032] The elastic force of the first return spring 136 is smaller than the elastic force of the second return spring 146. The elastic force of the first return spring 136 is designed to be smaller than the elastic force of the second return spring 146. This design is to give priority to protecting the horizontal sliding structure 13 during the movement process to prevent damage to the wedge seat 131, the first connecting plate 133 and other components due to excessive extrusion. When the wedge seat 131 and the first connecting plate 133 are subjected to a large horizontal thrust, the first return spring 136 can be deformed before the second return spring 146, thereby playing a buffering role. The wedge buckle 135 is fixedly connected to the second connecting plate 134. After the wedge buckle 135 contacts the gear rod 144, the wedge buckle 135 is deformed. 35 reversely squeezes the first return spring 136 through the second connecting plate 134, causing the first return spring 136 to deform. The wedge-shaped clip 135 is fixedly connected to the second connecting plate 134. When the wedge-shaped clip 135 contacts the gear rod 144, the wedge-shaped clip 135 reversely squeezes the first return spring 136 through the second connecting plate 134, causing the first return spring 136 to deform. This reverse extrusion design can effectively prevent the first connecting plate 133 from continuing to slide, thereby avoiding damage to the wedge-shaped clip 135 and the gear rod 144 due to excessive extrusion. Through the elastic buffering of the first return spring 136, the device can remain stable during complex movements, thereby extending its service life.

[0033] In the embodiments of the present invention, please refer to Figure 10-14 The top of the radial sleeve 141 is provided with a groove, and one end of the piston rod of the double-piston-rod cylinder 11 passes through the groove and is fixedly connected to a wedge seat 131 of the two wedge seats 131 away from the rotating seat structure 3. This design allows the piston rod to slide smoothly in the groove, and at the same time provides a guide for the movement of the piston rod to ensure the accuracy of its movement. The other end of the piston rod is fixedly connected to a T-shaped plate 132 of the two T-shaped plates 132 close to the rotating seat structure 3. This connection method enables the cylinder double-piston-rod cylinder 11 to directly drive the wedge seat 131 to slide horizontally, and the other end of the piston rod is fixedly connected to a T-shaped plate 132 of the two T-shaped plates 132 close to the rotating seat structure 3. This design enables the thrust of the cylinder double-piston-rod cylinder 11 to be transmitted to the entire horizontal sliding structure 13 through the T-shaped plate 132, thereby realizing the pushing and clamping functions of the steel pipe.

[0034] In the embodiments of the present invention, please refer to Figure 2-3The rotating seat structure 3 includes a ring frame 31, and two support seats 32 are symmetrically installed on the ring frame 31. The welding gun 8 is installed in the support seat 32. The welding gun 8 is installed in the support seat 32. This symmetrical installation method enables the two welding guns 8 to synchronously weld the joints of the steel pipes from different positions. This design not only improves the welding efficiency, but also ensures the uniformity and quality of the welding. The swivel structure 2 includes a connecting ring 21 fixedly installed on one side of the ring frame 31, and a collar 22 is fixedly provided on the side of the connecting ring 21 away from the ring frame 31. The connecting ring 21 and the collar 22 are fixedly connected to the side of the rotating seat structure 3 away from the rotating seat structure 3. A blocking ring 24 is fixedly provided between the blocking ring 24 and the collar 22 and the connecting ring 21. A convex ring 23 is rotatably provided. This structure is mutually engaged and the resistance component is shifted, so that the swivel structure 2 can rotate around the ring The frame 31 rotates stably to provide support for the rotation operation during the welding process. The side of the convex ring 23 away from the rotating seat structure 3 is fixedly connected to the pipe sleeve 7, and the steel pipe is fixed inside the pipe sleeve 7. This fixing method ensures that the steel pipe remains stable during the welding process and will not be displaced or shaken due to external forces. The design of the pipe sleeve 7 can adapt to steel pipes of different diameters, improving the versatility and flexibility of the device. The blocking ring 24 drives the ring frame 31 to rotate by driving the connecting ring 21 and the sleeve ring 22, so that the two welding guns 8 on the ring frame 31 are welded around the connection of the steel pipe. This design enables the welding gun 8 to weld the connection of the steel pipe in all directions during the welding process, ensuring the uniformity and quality of the welding. At the same time, the steel pipe remains stationary in the pipe sleeve 7, avoiding the stress concentration problem caused by the rotation of the steel pipe itself.

[0035] In the embodiments of the present invention, please refer to Figure 2-3 A gear ring 4 is fixedly mounted on the outside of a connecting ring 21, and a motor 6 is fixedly mounted on the side wall of a pipe sleeve 7 on the side of the gear ring 4 away from the rotating seat structure 3. A gear 5 is fixedly connected to the rotating shaft of the motor 6, and the gear 5 is meshed with the gear ring 4. The motor 6 drives the gear 5 to rotate through the rotating shaft, and the rotating gear 5 drives the connecting ring 21 and the ring frame 31 to rotate through the gear ring 4. The meshing transmission of the gear 5 and the gear ring 4 driven by the motor 6 can efficiently transmit power to the connecting ring 21 and the ring frame 31, ensuring that the welding gun 8 can smoothly perform welding operations around the connection of the steel pipe. This transmission method not only improves the uniformity and flexibility of welding, but also reduces the energy loss during power transmission.

[0036] Through the cooperation of the wedge-shaped seat 131 and the gear rod 144 in the telescopic clamping structure 1, this device can adapt to steel pipes of different diameters, realize automatic clamping and pushing of the steel pipe, and ensure that the steel pipe remains stable during the welding process; by utilizing the swivel structure 2 and the rotating seat structure 3, in conjunction with the meshing transmission of the motor 6 driving the gear 5 and the gear ring 4, all-round rotation welding of the welding gun 8 is realized, while the steel pipe remains stationary, avoiding the stress concentration problem that may be caused by the steel pipe's own rotation, and improving the uniformity and quality of welding; through the thrust of the double-piston rod cylinder 11, the wedge-shaped seat 131 is driven to slide horizontally, and then the gear rod 144 is pushed to slide in the direction close to the rotating seat structure 3, so that the two steel pipes are automatically approached and in close contact, providing good initial conditions for welding, and preventing the steel pipe from being deformed due to excessive extrusion.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
