Description

Technical Field

[0001] This invention belongs to the field of electromechanical welding technology, specifically relating to an auxiliary welding device for on-site installation of large electromechanical facilities. Background Technology

[0002] The quality of installation and fixing of electromechanical facilities directly determines the stability and safety of the overall project. In the on-site installation of large electromechanical facilities (such as large wind turbines, port machinery, and tunnel boring machines), welding is one of the core processes, directly determining the installation accuracy and structural stability of the facilities. These facilities are large, heavy, and complex in structure. The installation sites are mostly outdoors, with harsh working conditions and limited space, making it impossible to use large welding equipment in workshops. Instead, auxiliary welding equipment suitable for on-site installation is used.

[0003] Many components in large electromechanical facilities require on-site welding. For typical metal pipe fittings (including pressure pipelines, fluid transport pipelines, and ventilation ducts), the pipes need to be pre-positioned and limited before welding, connecting the welding ends of two pipes together for on-site assembly. However, current pipe-connection processes rely on manual measurement and adjustment to bring the two pipes closer together. This process involves significant adjustment errors, making it difficult to guarantee straightness and misalignment, thus affecting welding efficiency and quality. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary welding device for on-site installation of large-scale electromechanical facilities that is simple in structure and reasonably designed in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: An auxiliary welding device for on-site installation of large electromechanical facilities includes: The support mechanism includes a base, a limiting post, an abutment component, a rotation drive component, and a tilt adjustment component. The rotation drive component is mounted on the base, and its output end is connected to the limiting post. The limiting post is used to sequentially mount the first and second pipes to be welded. The abutment component is located on one side of the limiting post and is used to abut and position the first and second pipes on the limiting post. The output end of the tilt adjustment component is hinged to one end of the base, and the other end of the base is movably connected to the tilt adjustment component. The tilt adjustment component is used to adjust the tilt angle of the base to control the limiting post to switch between a loading position, a welding position, and an initial position. Specifically, the limiting post is in a first tilt state when it is in the loading position, in a second tilt state when it is in the welding position, and in a horizontal state when it is in the initial position. A welding robotic arm is mounted on one side of the support mechanism. The welding robotic arm is used to perform welding on the weld seams of the first and second pipes after they have been positioned.

[0006] As a further optimization of the present invention, under the drive of the tilt adjustment component, the first tilt state and the second tilt state of the limiting post are different, and the tilt angle of the limiting post when it is in the feeding position is smaller than the tilt angle of the limiting post when it is in the welding position.

[0007] As a further optimization of the present invention, the indexing drive assembly includes a turntable, a support, a drive gear, a driven gear, and a first motor. The output end of the first motor is connected to the drive gear, which meshes with the driven gear. The driven gear is fixedly mounted on the turntable. The turntable is rotatably mounted on the support. One end of the limiting post is fixedly mounted on the turntable, wherein the axis of the limiting post is eccentrically set with respect to the axis of the turntable.

[0008] As a further optimization of the present invention, the abutting assembly includes an abutting post, a support post, a side rod, and a clamping drive component. The clamping drive component is disposed on the turntable and located on the side of the turntable away from the driven gear. The output end of the clamping drive component is drivenly connected to the support post. The support post is located below the limiting post. A side rod is fixedly disposed on the side of the support post. The side rods are arranged in pairs and are correspondingly fixedly connected to the abutting post. When the limiting post is in the welding position, the abutting post is located inside the first pipe and the second pipe and abuts against the inner wall of the first pipe and the second pipe.

[0009] As a further optimization of the present invention, the base is further provided with an abutting component on the side facing the limiting post. The abutting component is used to sequentially push the first pipe and the second pipe on the limiting post down to the target position along the tilt direction of the limiting post.

[0010] As a further optimization of the present invention, the abutting component includes an abutting block, a first linear drive component, a slide block, and a second linear drive component. The second linear drive component is disposed on the base, and the output end of the second linear drive component is drivenly connected to the slide block. The first linear drive component is disposed on the slide block, and the output end of the first linear drive component is drivenly connected to the abutting block. The second linear drive component is used to drive the slider to move along the axis of the limiting post, and the first linear drive component is used to drive the abutting block to move along the axis perpendicular to the limiting post.

[0011] As a further optimization of the present invention, the first linear drive assembly includes a lifting drive component, which is mounted on a slide block and has an abutment block fixedly connected to its output end. The second linear drive assembly includes a second motor, a lead screw, and a slide rail. The output end of the second motor is connected to the lead screw, which passes through the slide block and is threadedly connected to the slide block. The lead screw is rotatably mounted on the slide rail, the slide rail is fixedly mounted on the base, and the slide block is slidably mounted on the slide rail.

[0012] As a further optimization of the present invention, a groove is provided on the side of the turntable away from the driven gear, and a slide plate is slidably installed in the groove. The sliding direction of the slide plate and the groove is perpendicular to the axis of the limiting shaft, and a spring is fixedly provided at the lower end of the slide plate, and the other end of the spring is fixedly connected to the inner wall of the groove.

[0013] As a further optimization of the present invention, the tilt adjustment assembly includes a movable plate, an adjustment drive component, and a base. One end of the movable plate is rotatably mounted on the base, the adjustment drive component is disposed on the base, and the driving end of the adjustment drive component is rotatably connected to the other end of the movable plate. The base is fixedly disposed on the upper surface of the movable plate.

[0014] As a further optimization of the present invention, a support seat is also provided on the base. The support seat is located on the side of the adjustment drive component away from the rotation connection point between the movable plate and the base. When the movable plate is in the initial position, the lower end surface of the movable plate abuts against the upper end surface of the support seat.

[0015] The present invention has at least the following beneficial effects: The present invention provides an auxiliary welding equipment for on-site installation of large electromechanical facilities, including a support mechanism and a welding robotic arm. The support mechanism includes a base, a limiting post, an abutment component, a rotation drive component, and an tilt adjustment component. The tilt adjustment component adjusts the state of the base so that the limiting post is in an inclined state when the material is loaded. The first pipe and the second pipe to be welded are sequentially fitted onto the limiting post. With the help of the pipe's own gravity, the first pipe and the second pipe are hung on the limiting post, and the facing surfaces of the two pipes abut against each other, thereby achieving the pre-positioning of the first pipe and the second pipe relative to the limiting post. This eliminates the need for multiple manual adjustments to the pipe docking process, reduces adjustment errors, and ensures the welding efficiency and welding quality of the pipes. Moreover, under the drive of the tilt adjustment component, the first tilt state and the second tilt state of the limiting post are different, and the tilt angle of the limiting post when it is in the feeding position is smaller than the tilt angle of the limiting post when it is in the welding position. This increases the tilt angle of the first pipe and the second pipe during welding relative to the feeding position, that is, increases the axial thrust of the second pipe on the first pipe by its own weight, thereby ensuring a tight fit between the end faces of the second pipe and the first pipe, and making the welding more stable. In addition, an abutment component is provided on the base. The abutment component includes an abutment block, a first linear drive component, a slide, and a second linear drive component. The abutment block provides lateral abutment support to the pipe, causing the pipe to tilt relative to the limiting post. This reduces the contact area between the first pipe and the limiting post from line contact to point contact, thereby reducing the frictional resistance between the first pipe and the limiting post and thus improving the efficiency of the first pipe sliding down the limiting post. Furthermore, a sliding plate is installed at the turntable position, and a spring is installed between the lower end of the sliding plate and the chute. When the first pipe slides down at an angle relative to the limiting post, the lower end of the right end face of the first pipe first abuts against the sliding plate. After the abutting block is removed, under the action of the first pipe's own gravity, the first pipe will return to a state where it is not tilted relative to the limiting post. The lower end of the right end face of the first pipe will abut against the sliding plate and cause the sliding plate to slide down and compress the spring, so that the right end face of the first pipe finally fits against the sliding plate. There is no relative sliding friction between the first pipe and the sliding plate. Especially in the case of welding multiple pipes at the installation site of large facilities, it can extend the service life of the welding equipment. Attached Figure Description

[0018] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

They are only used to facilitate the description of this application and to simplify the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0020] like Figure 1 and Figure 2 As shown, the present invention provides an auxiliary welding device for on-site installation of large electromechanical facilities, comprising: The support mechanism 2 includes a base 25, a limiting post 21, an abutment component 22, a rotation drive component 23, and a tilt adjustment component 26. The rotation drive component 23 is mounted on the base 25, and its output end is connected to the limiting post 21. The limiting post 21 is used to sequentially mount the first pipe 31 and the second pipe 3 to be welded. The abutment component 22 is mounted on one side of the limiting post 21 and is used to abut and position the first pipe 31 and the second pipe 3 on the limiting post 21. The output end of the tilt adjustment component 26 is hinged to one end of the base 25, and the other end of the base 25 is movably connected to the tilt adjustment component 26. The tilt adjustment component 26 is used to adjust the tilt angle of the base 25 to control the limiting post 21 to switch between the loading position, the welding position, and the initial position. When the limiting post 21 is in the loading position, it is in the first tilt state; when it is in the welding position, it is in the second tilt state; and when it is in the initial position, it is in the horizontal state. A welding robotic arm 1 is set on one side of the support mechanism 2. The welding robotic arm 1 is used to perform welding treatment on the weld seam of the first pipe 31 and the second pipe 3 after positioning.

[0021] In the above embodiment, the state of the base 25 is adjusted by the tilt adjustment component 26 so that the limiting post 21 is tilted when it is moved to the loading position. At this time, the first pipe 31 and the second pipe 3 are sequentially connected to the tilted limiting post 21. With the help of the gravity of the pipes themselves, the first pipe 31 and the second pipe 3 are hung on the limiting post 21, and the facing surfaces of the two pipes abut against each other, thereby achieving the pre-positioning of the first pipe 31 and the second pipe 3 relative to the limiting post 21. There is no need for manual adjustment of the pipe docking process multiple times. Furthermore, with the clamping and limiting of the abutment component 22, the first pipe 31 and the second pipe 3 are fixed with the limiting post 21 as a unified reference. Under the drive of the rotation drive component 23, the limiting post 21 drives the two pipes to rotate, thereby completely exposing the weld seams of the two pipes for welding processing by the welding robot arm 1, ensuring the welding efficiency and welding quality of the pipes.

[0022] It should be noted that the weld joint of the first pipe 31 and the second pipe 3 is located on the left end face of the first pipe 31 (within...). Figure 2 (taking orientation as an example) and the right end face of the second pipe 3 (taking Figure 2 (Taking orientation as an example) The position of the circumferential gap formed after the contact.

[0023] In other embodiments, the first tilt state and the second tilt state of the limiting post 21 are the same, that is, the feeding position and the welding position of the limiting post 21 are the same position. That is, after the limiting post 21 completes the feeding of the two pipes in the first tilt state, the welding operation of the pipes can be carried out in the tilt state.

[0024] Preferably, under the drive of the tilt adjustment component 26, the first tilt state and the second tilt state of the limiting post 21 are different, that is, the first tilt state and the second tilt state of the limiting post 21 are inconsistent, and the tilt angle of the limiting post 21 when it is in the feeding position is smaller than the tilt angle of the limiting post 21 when it is in the welding position. (Continue reading) Figure 6 and Figure 7 , Figure 6 The diagram simply illustrates the inclination angle α of the limiting post 21 when it is in the feeding position. In this inclined state, the first pipe 31 is first hung on the limiting post 21. After the first pipe 31 slides down the limiting post 21 to its lower end, the feeding of the second pipe 3 is simultaneously operated, causing the second pipe 3 to come into contact with the first pipe 31. Then, refer to... Figure 7 Under the continued drive of the tilt adjustment component 26, the tilt angle of the limiting post 21 when it is in the welding position is α'. It can be seen that α' > α, which increases the tilt angle of the first pipe 31 and the second pipe 3 during welding, that is, increases the axial thrust of the second pipe 3 on the first pipe 31 by its own weight, thereby ensuring the tight fit between the two pipe end faces of the second pipe 3 and the first pipe 31, making the welding more stable.

[0025] For example, see [link to relevant documentation]. Figure 2 The indexing drive assembly 23 includes a turntable 211, a support 234, a drive gear 232, a driven gear 233, and a first motor 231. The output end of the first motor 231 is connected to the drive gear 232, which meshes with the driven gear 233. The driven gear 233 is fixedly mounted on the turntable 211, which is rotatably mounted on the support 234. One end of the limiting post 21 is fixedly mounted on the turntable 211, with the axis of the limiting post 21 being eccentrically set to the axis of the turntable 211. Thus, after the abutment assembly 22 positions and fixes the first pipe 31 and the second pipe 3 to the welding position, the first motor 231 drives the drive gear 232, which in turn drives the driven gear 233, causing the turntable 211 to rotate and the limiting post 21 to rotate with the limiting post 21, allowing the welding robot arm 1 to perform welding on the weld seam.

[0026] For example, see [link to relevant documentation]. Figure 3 and Figure 4The abutment component 22 includes an abutment post 221, a support post 222, a side rod 223, and a clamping drive component 224. The clamping drive component 224 is disposed on the turntable 211 and located on the side of the turntable 211 away from the driven gear 233. The output end of the clamping drive component 224 is connected to the support post 222. The support post 222 is located below the limiting post 21. The side rod 223 is fixedly disposed on the side of the support post 222. The side rods 223 are arranged in pairs and are correspondingly fixedly connected to the abutment post 221. When the limiting post 21 is in the welding position, the abutment post 221 is located inside the first pipe 31 and the second pipe 3 and abuts against the inner walls of the first pipe 31 and the second pipe 3. Before hanging the pipe on the limiting post 21, the clamping drive 224 is used to drive the support post 222 upward to the initial position. After the two pipes are loaded, the clamping drive 224 is driven again, causing the support post 222 to move the abutment post 221 downward through the side rod 223, until the abutment post 221 abuts against the inner wall of the pipe. Figure 5 As shown, the abutment points of the paired abutment posts 221 and the pipes, and the abutment points of the limiting posts 21 and the pipes are triangularly symmetrically supported, ensuring that the first pipe 31 and the second pipe 3 are aligned and fixed, without misalignment.

[0027] The clamping drive component 224 can be a hydraulic telescopic cylinder, an electric telescopic cylinder, or an electrically operated telescopic cylinder; no specific limitation is made here.

[0028] For example, see [link to relevant documentation]. Figure 2 and Figure 8 The tilt adjustment assembly 26 includes a movable plate 261, an adjustment drive component 262, and a base 263. One end of the movable plate 261 is rotatably mounted on the base 263. The adjustment drive component 262 is disposed on the base 263, and the driving end of the adjustment drive component 262 is rotatably connected to the other end of the movable plate 261. The base 25 is fixedly disposed on the upper surface of the movable plate 261.

[0029] It should be noted that the adjusting drive component 262 can be a hydraulic telescopic cylinder, an electric telescopic cylinder, or an electrically operated telescopic cylinder; no specific limitation is made here. By adjusting the drive component 262, the movable plate 261 is driven to rotate around the rotational connection point between the movable plate 261 and the base 263, thereby enabling the movable plate 261 to drive the base 25 to adjust its tilt angle.

[0030] Among them, such as Figure 8 As shown, a support base 264 is also provided on the base 263. The support base 264 is located on the side of the adjusting drive component 262 away from the rotational connection point between the movable plate 261 and the base 263, that is, with Figure 8Taking orientation as an example, the rotation connection point of the movable plate 261 and the base 263 is located on the left side of the adjusting drive component 262, and the support base 264 is located on the right side of the adjusting drive component 262. After welding is completed, the movable plate 261 is adjusted to a horizontal state, that is, the movable plate 261 is in the initial position. At this time, the lower end of the movable plate 261 abuts against the support base 264 to realize the auxiliary support of the support base 264 for the movable plate 261.

[0031] For example, see [link to relevant documentation]. Figure 2 The base 25 is also provided with an abutment component 24 on the side facing the limiting post 21. The abutment component 24 is used to push the first pipe 31 and the second pipe 3 on the limiting post 21 to slide down to the target position along the tilt direction of the limiting post 21 in sequence.

[0032] For example, see [link to relevant documentation]. Figure 3 The abutment component 24 includes an abutment block 241, a first linear drive component, a slide block 243, and a second linear drive component. The second linear drive component is disposed on the base 25, and the output end of the second linear drive component is connected to the slide block 243. The first linear drive component is disposed on the slide block 243, and the output end of the first linear drive component is connected to the abutment block 241. The second linear drive component is used to drive the slider to move along the axis of the limiting post 21, and the first linear drive component is used to drive the abutment block 241 to move along the axis perpendicular to the limiting post 21.

[0033] Continue reading Figure 6 Taking the first pipe 31 as an example, before the first pipe 31 is hung on the limiting post 21, the abutment block 241 is in its initial position. At this time, the process of hanging the first pipe 31 on the limiting post 21 will not scrape the abutment block 241. After the first pipe 31 is hung on the limiting post 21, the abutment block 241 is moved upward by the drive of the first linear drive component, and the slide block 243 is moved to the right by the drive of the second linear drive component. Finally, the abutment block 241 abuts against the left end face of the first pipe 31. Under the continued drive of the second linear drive component, the abutment block 241 is moved to the right, and the first pipe 31 is moved from the left end face of the first pipe 31 to the right end face of the first pipe 31. Figure 6 The position indicated by the dashed line will swing counterclockwise to the position indicated by the solid line. It should be noted that the position of the first pipe 31 indicated by the dashed line represents its natural state when suspended from the limiting post 21. Figure 6To clearly illustrate the positional change of the first pipe 31 before and after contact, the swing amplitude of the first pipe 31 is magnified. Through the lateral contact support of the contact block 241, the contact block 241 provides a lateral support force to the first pipe 31, causing the first pipe 31 to tilt relative to the limiting post 21. This reduces the contact area between the first pipe 31 and the limiting post 21 from line contact to point contact, thereby reducing the frictional resistance between the first pipe 31 and the limiting post 21, thus improving the efficiency of the first pipe 31 sliding down the limiting post 21. The second pipe 3 is operated similarly, and will not be described in detail here.

[0034] Continue to refer to Figure 3 and Figure 4 A groove 237 is provided on the side of the turntable 211 away from the driven gear 233. A slide plate 235 is slidably installed in the groove 237. The sliding direction of the slide plate 235 and the groove 237 is perpendicular to the axis of the limiting shaft. A spring 236 is fixedly installed at the lower end of the slide plate 235. The other end of the spring 236 is fixedly connected to the inner wall of the groove 237. When the first pipe 31 slides down against the abutment block 241, the first pipe 31, which is tilted relative to the limiting post 21, first abuts against the sliding plate 235. At this time, the right end face of the tilted first pipe 31 is not parallel to the sliding plate 235. Instead, the lower end of the right end face of the tilted first pipe 31 abuts against the sliding plate 235 first. After the abutment block 241 is removed, under the action of the first pipe 31's own gravity, the first pipe 31 will return to a state where it is not tilted relative to the limiting post 21. At this time, the lower end of the right end face of the first pipe 31 will abut against the sliding plate 235 and cause the sliding plate 235 to slide down along the slide groove 237 and compress the spring 236, so that the right end face of the first pipe 31 finally fits against the sliding plate 235. That is, there is no relative sliding friction between the first pipe 31 and the sliding plate 235. Especially in the installation site of large facilities, the welding operation of multiple pipes can extend the service life of the welding equipment through the above method. The second pipe 3 is then pushed down by the abutment block 241 to the lower right end of the second pipe 3, first abutting the left end of the first pipe 31. After the abutment block 241 is removed, the second pipe 3 will return to a state where it is not tilted relative to the limit post 21 under its own gravity, that is, the right end of the second pipe 3 is completely abutting the left end of the first pipe 31.

[0035] For example, see [link to relevant documentation]. Figure 3 The first linear drive assembly includes a lifting drive component 242, which is mounted on a slide 243. The output end of the lifting drive component 242 is fixedly connected to an abutment block 241. The lifting drive component 242 can be a hydraulic telescopic cylinder, an electric telescopic cylinder, or an electrical telescopic cylinder, which is not limited here.

[0036] The second linear drive assembly includes a second motor 246, a lead screw 244, and a slide rail 245. The output end of the second motor 246 is connected to the lead screw 244. The lead screw 244 passes through the slide block 243 and is threadedly connected to the slide block 243. The lead screw 244 is rotatably mounted on the slide rail 245. The slide rail 245 is fixedly mounted on the base 25, and the slide block 243 is slidably mounted on the slide rail 245.

[0037] It should be noted that the auxiliary welding equipment used for on-site installation of this large electromechanical facility is tilted at an angle α by adjusting the movable plate 261 through the adjustment of the drive component 262 during use. Figure 6 As shown, at this time, the limiting post 21 is in the feeding position, the abutting post 221 is in the initial position, and the abutting block 241 is also in the initial position; Then, the first pipe 31 is first hung on the limiting post 21. The lifting drive 242 drives the abutment block 241 to move upward. Under the drive of the second motor 246, the lead screw 244 drives the slide block 243 to move to the right, so that the abutment block 241 moves to the right and abuts against the left end face of the first pipe 31, providing lateral abutment support for the first pipe 31. This causes the first pipe 31 to tilt relative to the limiting post 21. Under the continued drive of the second motor 246, the slide block 243 continues to move to the right, causing the first pipe 31 to tilt. The pipe slides down the limiting post 21 at a relatively inclined position until the lower end of the right end face of the first pipe 31 first abuts against the sliding plate 235. After removing the abutment block 241, the first pipe 31 will return to a state where it is not inclined relative to the limiting post 21 under its own gravity. At this time, the lower end of the right end face of the first pipe 31 will abut against the sliding plate 235 and cause the sliding plate 235 to slide down the slide groove 237 and compress the spring 236, so that the right end face of the first pipe 31 finally fits against the sliding plate 235. The second pipe 3 is first hung on the limiting post 21, and the above operation of the abutment block 241 is repeated so that the lower end of the right end face of the second pipe 3 first abuts against the left end face of the first pipe 31. After the abutment block 241 is removed, under the action of the second pipe 3's own gravity, the second pipe 3 will return to a state where it is not tilted relative to the limiting post 21, that is, the right end face of the second pipe 3 is completely abutted against the left end face of the first pipe 31. Next, the clamping drive 224 is activated, causing the support column 222 to move the abutment column 221 downward through the side rod 223, so that the abutment column 221 abuts against the inner wall of the first pipe 31 and the second pipe 3, thereby clamping and fixing the first pipe 31 and the second pipe 3. Furthermore, the abutment block 241 is abutted against the left end face of the second pipe 3 again to further clamp and fix the first pipe 31 and the second pipe 3. Then, continue driving the adjustment drive component 262, causing the movable plate 261 to drive the base 25 to continue tilting, causing the base 25 to tilt at an angle α', as shown. Figure 7As shown, at this time, the first motor 231 is started, causing the driving gear 232 to mesh with the driven gear 233, and the turntable 211 rotates, causing the limiting post 21 to drive the first pipe 31 and the second pipe 3 to rotate, thereby welding the weld seam of the first pipe 31 and the second pipe 3 through the welding robot arm 1.
