Description
Technical Field
[0001] This invention relates to the field of pile foundation construction technology, and in particular to a pipe pile butt welding device and a pipe pile butt welding method. Background Technology
[0002] Pipe piles, as a common type of precast concrete pile or prestressed concrete pile, are widely used in pile foundation construction for building engineering, bridge engineering, port and wharf projects. During construction, multiple pipe pile sections are usually connected into an integral structure through a butt joint process. The quality of the butt joint directly affects the bearing capacity and long-term durability of the pile foundation, and is a key factor in determining the quality of the project.
[0003] Traditional construction techniques mainly rely on manual welding to complete the pipe pile connection. This method is not only inefficient, but the welding quality is also greatly affected by the operator's skill level, making it difficult to guarantee stability and consistency. To solve this problem, existing technical solutions generally use pipe pile welding robots. The pipe pile welding robot can achieve automated welding in the circumference of the pipe pile by using a walking track installed on the outer circumference of the pipe pile. However, existing automatic welding solutions generally have the following shortcomings: (1) The length and curvature of the walking track are fixed, which makes it impossible to adjust the walking track according to the specifications of the pipe pile; (2) The distance between the pipe pile welding robot and the walking track is fixed, which makes it impossible to adjust the pipe pile welding robot according to the specifications of the pipe pile, limiting the versatility of the pipe pile welding robot in the construction of pipe piles of different specifications; (3) The pipe pile welding robot does not have the function of detecting welding quality, which requires manual re-inspection of the weld quality after the connection is completed, which significantly increases the construction period and cost.
[0004] Therefore, there is an urgent need for pipe pile welding equipment and pipe pile welding method to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a pipe pile butt welding device and a pipe pile butt welding method, which can be installed on pipe piles of different specifications, expanding the versatility of the pipe pile butt welding device. It also has a weld inspection function, so that no manual re-inspection is required after welding, which significantly reduces the construction period and cost of pipe pile docking.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] On the one hand, a pipe pile butt welding device is provided, comprising:

The traveling component is detachably mounted on the flexible track body and can move along the circumference of the pipe pile. The length of the traveling component along the extension direction of the flexible track body is adjustable. When the extension length of the traveling component changes, the traveling component can drive the linkage component to drive the support to move radially along the pipe pile.
[0010] The walking drive mechanism is mounted on the support frame. The output end of the walking drive mechanism can be connected to the flexible track body to drive the connecting mechanism to move circumferentially along the pipe pile.

[0016] Optionally, the bracket is provided with a waist-shaped hole, and the connecting mechanism also includes a connecting shaft, which passes through the second connector, the first connector and the waist-shaped hole, and is rotatably engaged with the second connector, the first connector and the waist-shaped hole, and the position of the connecting shaft in the waist-shaped hole is adjustable.
[0017] Optionally, the flexible track body is provided with a rack extending along its extension direction, and the walking drive mechanism includes a second rotary drive member and a connecting gear. The connecting gear is rotatably mounted on the bracket and can mesh with the rack. The output end of the second rotary drive member is connected to the connecting gear and is used to drive the connecting gear to rotate.
[0018] Optionally, the track mechanism also includes a plurality of first pushing members disposed on the flexible track body. The plurality of first pushing members are arranged at intervals along the extension direction of the flexible track body, and the first pushing members can abut against the outer wall of the pipe pile.
[0019] And / or, the track mechanism also includes a plurality of second pushing members disposed on the flexible track body, the plurality of second pushing members being arranged at intervals along the extension direction of the flexible track body, the second pushing members being able to abut against the outer wall of the pipe pile, and the extension length of the second pushing members being adjustable.
[0020] Optionally, the flexible track body includes multiple arc-shaped track slabs and multiple connecting plates. The multiple arc-shaped track slabs are continuously arranged along the circumference of the pipe pile, and the ends of any two adjacent arc-shaped track slabs are spliced together. A connecting plate is provided at the splice of any two adjacent arc-shaped track slabs. One end of the connecting plate is detachably connected to one of the two adjacent arc-shaped track slabs, and the other end is detachably connected to the other of the two adjacent arc-shaped track slabs.
[0021] Optionally, the pipe pile welding equipment also includes a working drive mechanism, which includes a first drive component, a second drive component, a third drive component, a first base, and a second base. The first drive component is mounted on a support, the second drive component is mounted on the first base, and the third drive component and the working mechanism are both mounted on the second base.

The output end of the third drive component is connected to the welding torch and is used to drive the welding torch to swing up and down.
[0022] On the other hand, a method for butt welding pipe piles is provided, which uses the aforementioned pipe pile butt welding equipment to weld two sections of pipe piles, including the following steps:
[0023] S1. Install the flexible track body onto the outer periphery of the pipe pile;
[0024] S2. Connect the walking component to the flexible track body and adjust the extension length of the walking component so that the output end of the walking drive mechanism can be connected to the flexible track body.
[0025] S3. Turn on the welding torch and weld the pipe pile. At the same time, control the walking drive mechanism to drive the connecting mechanism to move the welding torch around the circumference of the pipe pile until the welding torch has circled the pipe pile once.
[0026] S4. Open the inspection component. The inspection component inspects the weld quality. At the same time, control the walking drive mechanism to drive the connecting mechanism to move the inspection component along the circumference of the pipe pile.
[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0028] This invention provides a pipe pile welding device and a pipe pile welding method. The flexible track body has a certain degree of flexibility, meaning it can be bent, allowing it to be installed onto the pipe pile through bending. When installing the track mechanism onto the pipe pile, adjusting the extension length of the flexible track body allows it to adapt to pipe piles of different circumferences. Bending the flexible track body allows it to be adapted to pipe piles with different degrees of curvature, ensuring that the flexible track body can be installed onto pipe piles of different specifications, thus improving the versatility of the pipe pile welding device provided by this invention. The walking component and the flexible track body can be detachably connected. When installing the flexible track body onto the pipe pile, the walking component can be separated from the flexible track body first, avoiding interference from the connecting mechanism, improving the convenience of installation, and ensuring the safety of the installation process. When the length of the walking component is changed, the walking component can drive the support to move radially along the pipe pile through the linkage component. The support drives the walking drive mechanism to move together. Thus, when the pipe pile specifications change, the distance between the output end of the walking drive mechanism and the flexible track body can be adaptively adjusted by adjusting the radial movement of the support along the pipe pile. This ensures that the output end of the walking drive mechanism can always be connected to the flexible track body and effectively avoids the connection between the output end of the walking drive mechanism and the flexible track body being too tight, which would affect the driving effect. As a result, the connecting mechanism and the working mechanism can be installed on pipe piles of different specifications, further improving the versatility of the pipe pile welding equipment provided by this invention. The welding torch is turned on, allowing it to weld the joint between two pipe pile sections. Simultaneously, the travel drive mechanism moves the connecting mechanism along the circumference of the pipe pile, and the support moves the welding torch along with it, enabling the welding torch to weld the pipe pile circumferentially. After welding is completed, the inspection piece is activated, allowing it to inspect the weld quality. At the same time, the connecting mechanism is driven to move along the circumference of the pipe pile, and the support moves the inspection piece along with it, enabling the inspection piece to inspect the entire length of the weld. The operation is convenient and quick, eliminating the need for manual re-inspection and significantly reducing the construction period and cost of pipe pile docking. Attached Figure Description

[0051] Example 1
[0052] like Figures 1 to 9 As shown, this embodiment provides a pipe pile butt welding device that can be installed on pipe piles 100 of different specifications, expanding the versatility of the pipe pile butt welding device. It also has a weld inspection function, so that no manual re-inspection is required after welding, which significantly reduces the construction period and cost of pipe pile 100 butt welding.
[0053] See Figure 1 and Figure 2 The pipe pile welding equipment includes a track mechanism 1, a connecting mechanism 2, a traveling drive mechanism 3, and a working mechanism 4. The track mechanism 1 includes a flexible track body 11, which extends circumferentially along the pipe pile 100 and its extension length is adjustable. The connecting mechanism 2 includes a support 21, a linkage component 22, and a traveling component 23. The support 21 is movably disposed on the side of the flexible track body 11 away from the pipe pile 100 and is connected to the traveling component 23 through the linkage component 22. The traveling component 23 is detachably disposed on the flexible track body 11 and can move circumferentially along the pipe pile 100. The length of the flexible track body 11 is adjustable. When the extension length of the walking component 23 changes, the walking component 23 can drive the linkage component 22 to drive the support 21 to move radially along the pipe pile 100. The walking drive mechanism 3 is set on the support 21. The output end of the walking drive mechanism 3 can be connected to the flexible track body 11 to drive the connecting mechanism 2 to move circumferentially along the pipe pile 100. The working mechanism 4 is movably set on the support 21. The working mechanism 4 includes a welding gun 41 and a detection component 42. The welding gun 41 is configured to weld the pipe pile 100, and the detection component 42 is configured to detect the weld quality.
[0054] The pipe pile welding equipment provided in this embodiment features a flexible track body 11 with a certain degree of flexibility, meaning it can be bent, allowing it to be installed onto the pipe pile 100 through bending. When installing the track mechanism 1 onto the pipe pile 100, adjusting the extension length of the flexible track body 11 allows it to adapt to pipe piles 100 of different circumferences. Bending the flexible track body 11 allows it to be adapted to pipe piles 100 with different degrees of bending, ensuring that the flexible track body 11 can be installed onto pipe piles 100 of different specifications, thus improving the versatility of the pipe pile welding equipment provided in this embodiment. The walking component 23 is detachably connected to the flexible track body 11. When installing the flexible track body 11 onto the pipe pile 100, the walking component 23 can be separated from the flexible track body 11 first, preventing the connecting mechanism 2 from affecting the installation of the flexible track body 11, improving the convenience of installation, and ensuring the safety of the installation process. When the extension length of the walking component 23 is changed, the walking component 23 can drive the support 21 to move radially along the pipe pile 100 through the linkage component 22. The support 21 drives the walking drive mechanism 3 to move together. Thus, when the specifications of the pipe pile 100 change, the distance between the output end of the walking drive mechanism 3 and the flexible track body 11 can be adaptively adjusted by adjusting the radial movement of the support 21 along the pipe pile 100. This ensures that the output end of the walking drive mechanism 3 can always be connected to the flexible track body 11, and effectively avoids that the output end of the walking drive mechanism 3 is too tightly connected to the flexible track body 11, which would affect the driving effect. This allows the connecting mechanism 2 and the working mechanism 4 to be installed on pipe piles 100 of different specifications, further improving the versatility of the pipe pile welding equipment provided in this embodiment. When the welding torch 41 is turned on, it can weld the joint of the two pipe piles 100. At the same time, the walking drive mechanism 3 drives the connecting mechanism 2 to move around the pipe pile 100. The bracket 21 can drive the welding torch 41 to move together, so that the welding torch 41 can weld the pipe pile 100 around the circumference. After the welding is completed, the inspection piece 42 is turned on, so that the inspection piece 42 can inspect the weld quality. At the same time, the connecting mechanism 2 is driven to move around the pipe pile 100. The bracket 21 drives the inspection piece 42 to move together, so that the inspection piece 42 can inspect the entire length of the weld. The operation is convenient and quick, and no manual re-inspection is required. This significantly reduces the construction period and cost of the pipe pile 100 docking.
[0055] Optionally, see Figure 1 and Figure 3The working mechanism 4 also includes a mounting base 43 and a protective cover 44. The mounting base 43 is movably mounted on the bracket 21. The welding torch 41 and the inspection piece 42 are both mounted on the mounting base 43. The protective cover 44 is rotatably mounted on the mounting base 43 and has a protective position covering the inspection piece 42 and an inspection position away from the inspection piece 42. When the welding torch 41 welds the pipe pile 100, the protective cover 44 is in the protective position. When the inspection piece 42 inspects the weld quality, the protective cover 44 is in the inspection position. In the protective position, the protective cover 44 can prevent the inspection piece 42 from being damaged by the welding slag, thus improving the service life of the inspection piece 42. During the inspection process, the protective cover 44 is away from the inspection piece 42, so that the protective cover 44 will not affect the inspection of the inspection piece 42, ensuring the smooth progress of the inspection operation.
[0056] For example, see Figure 4 The inspection component 42 includes a laser inspection camera 421 and a vision inspection camera 422. The laser inspection camera 421 uses a laser beam to scan and acquire precise three-dimensional data of the weld surface, enabling high-precision dimensional measurement and defect detection, especially suitable for applications with strict requirements on weld size and shape. The vision inspection camera 422 acquires two-dimensional images of the weld through an image sensor, providing a visual representation of the weld's appearance quality and adaptable to the inspection of welds of different shapes, sizes, and materials.
[0057] In this embodiment, the working mechanism 4 further includes a first rotary drive component disposed on the mounting base 43. The output end of the first rotary drive component is connected to the protective cover 44 for driving the protective cover 44 to rotate, and the first rotary drive component is electrically connected to the detection component 42. When the detection component 42 is opened or closed, the first rotary drive component will drive the protective cover 44 to rotate, so as to realize the automatic switching of the position of the protective cover 44, which is convenient and quick to operate and improves the automation level of the pipe pile 100 docking.
[0058] In this embodiment, the working mechanism 4 also includes an alarm that is electrically connected to the detection component 42. When the detection component 42 detects that the weld quality is unqualified, the alarm can sound an alarm to remind the workers of the location of the unqualified weld quality so that the workers can perform repair welding.
[0059] Optionally, see Figure 1 , Figure 5 and Figure 6The walking component 23 includes two walking wheels 231 spaced apart along the extension direction of the flexible track body 11. The distance between the two walking wheels 231 is adjustable, and the walking wheels 231 can roll in cooperation with the flexible track body 11. The linkage component 22 includes a first connecting member 221 corresponding to each of the two walking wheels 231. One end of the first connecting member 221 is hinged to the corresponding walking wheel 231, and the other end is hinged to the bracket 21. Driving the two walking wheels 231 to roll relative to each other along the flexible track body 11 changes the distance between the two walking wheels 231. The first connecting member 221 rotates, and the distance between the other end of the first connecting member 221 and the walking wheel 231 changes, thereby realizing the radial movement of the bracket 21 along the pipe pile 100. During the process of the walking drive mechanism 3 driving the connecting mechanism 2 to move circumferentially along the pipe pile 100, the distance between the two walking wheels 231 is kept fixed to ensure the stability of the connection between the output end of the walking drive mechanism 3 and the flexible track body 11.
[0060] Specifically, see Figure 2 and Figure 6 The traveling wheel 231 is provided with an annular groove 2311. The flexible track body 11 is made of plate, and the edge of the flexible track body 11 can be inserted into the annular groove 2311 and roll in cooperation with the groove wall, so that the traveling wheel 231 can move along the extension direction of the flexible track body 11. When connecting or separating the traveling component 23 from the flexible track body 11, the edge of the flexible track body 11 can be inserted into or released from the annular groove 2311. The operation is convenient and quick, and it is easy to use on the construction site.
[0061] In this embodiment, see Figure 1 , Figure 5 and Figure 6The linkage component 22 also includes a second connector 222 corresponding to each of the two first connectors 221. One end of the second connector 222 is hinged to the corresponding first connector 221, and the other end is hinged to the other second connector 222. The connection mechanism 2 also includes an operation component 24, which includes a first connecting seat 241, a second connecting seat 242, and an operation component 243. The other ends of the two first connectors 221 are hinged to the first connecting seat 241, and the other ends of the two second connectors 222 are hinged to the second connecting seat 242. The operation component 243 is radially inserted through the first connecting seat 241 and the second connecting seat 242 along the pipe pile 100 and is threadedly connected to both the first connecting seat 241 and the second connecting seat 242. Tightening the operating component 243 causes the first connecting seat 241 and the second connecting seat 242 to move axially. The first connecting seat 241 moves the other end of the first connecting member 221, and the second connecting seat 242 moves the other end of the second connecting member 222. This changes the distance between the other end of the first connecting member 221 and the other end of the second connecting seat 242, causing the first connecting member 221 and the second connecting member 222 to rotate. This changes the distance between the two traveling wheels 231, allowing the support 21 to move radially along the pipe pile 100. Furthermore, when the operating component 243 is not tightened, the threads between the operating component 243 and the first connecting seat 241 and the second connecting seat 242 restrict the movement of the first connecting seat 241 and the second connecting seat 242, thereby limiting the position of the support 21 and ensuring the stability of the connection between the output end of the traveling drive mechanism 3 and the flexible track body 11. In addition, the two second connectors 222 and the two first connectors 221 can form a parallelogram structure, which helps to improve the overall strength of the linkage assembly 22 and prevent the first connectors 221 from being damaged.
[0062] For example, the first connecting seat 241 is provided with a first threaded hole, the second connecting member 222 is provided with a second threaded hole, the operating member 243 is a bolt, and the thread direction of the first threaded hole is opposite to that of the second threaded hole, so that when the operating member 243 is screwed, the moving directions of the first connecting seat 241 and the second connecting seat 242 can be opposite, so that the first connecting member 221 and the second connecting member 222 can rotate when the operating member 243 is screwed.
[0063] Specifically, see Figure 3 and Figure 5The bracket 21 is provided with a waist-shaped hole 2121. The connecting mechanism 2 also includes a connecting shaft (not shown in the figure). The connecting shaft passes through the second connecting member 222, the first connecting member 221, and the waist-shaped hole 2121, and is rotatably engaged with the second connecting member 222, the first connecting member 221, and the waist-shaped hole 2121. The position of the connecting shaft within the waist-shaped hole 2121 is adjustable. When the first connecting member 221 rotates, the second connecting member 222 will rotate relative to the first connecting member 221. At the same time, the connecting shaft can move within the waist-shaped hole 2121 under the drive of the first connecting member 221 and the second connecting member 222 to cooperate with the rotation of the first connecting member 221 and the second connecting member 222, thereby improving the flexibility of the rotation of the first connecting member 221 and the second connecting member 222.
[0064] The waist-shaped hole 2121 can be set with one or two, as long as the two first connectors 221 and the two second connectors 222 can rotate flexibly.
[0065] For example, the connecting shaft is a pin.
[0066] For example, the first connecting seat 241, the other ends of the two first connecting members 221 and the bracket 21 are connected by a pin, the other ends of the two second connecting members 222 are connected to the second connecting seat 242 by a pin, and the first connecting seat 241 is also connected to the traveling wheel 231 by a pin.
[0067] In this embodiment, see Figure 1 and Figure 5 The walking component 23 and the linkage component 22 are each provided in two sets. The two sets of walking components 23 correspond one-to-one with the two sets of linkage components 22. The two sets of linkage components 22 are respectively located on both sides of the support 21 along the axial direction of the pipe pile 100, which helps to improve the connection strength between the connecting mechanism 2 and the track mechanism 1 and improve the stability of the connecting mechanism 2 installed on the track mechanism 1.
[0068] Optionally, see Figure 1 , Figure 7 and Figure 8 The flexible track body 11 is provided with a rack extending along its extension direction. The walking drive mechanism 3 includes a second rotary drive component 31 and a connecting gear 32. The connecting gear 32 is rotatably mounted on the bracket 21 and can mesh with the rack. The output end of the second rotary drive component 31 is connected to the connecting gear 32 to drive the connecting gear 32 to rotate. When the connecting gear 32 rotates, it can drive the bracket 21 to move along the extension direction of the rack, i.e., the circumferential direction of the pipe pile 100. The bracket 21 drives the walking wheel 231 to roll on the flexible track body 11 through the linkage component 22. At the same time, the bracket 21 drives the working mechanism 4 to move together, so that the welding torch 41 and the inspection component 42 can perform operations on the pipe pile 100.
[0069] For example, the second rotary drive 31 is a motor.
[0070] In this embodiment, see Figure 2 and Figure 7 The walking drive mechanism 3 also includes a planetary reducer 33. The output end of the second rotary drive component 31 is connected to the connecting gear 32 through the planetary reducer 33 to reduce the rotation speed of the connecting gear 32 and prevent the working mechanism 4 from moving too fast and affecting the construction quality.
[0071] See Figure 1 and Figure 7 The output end of the second rotary drive 31 extends radially along the pipe pile 100, and the connecting gear 32 rotates axially around the pipe pile 100. The walking drive mechanism 3 also includes a transmission assembly 34 disposed between the planetary reducer 33 and the connecting gear 32. The transmission assembly 34 includes several transmission gears and several transmission shafts so that the second rotary drive 31 can drive the connecting gear 32 to move.
[0072] For example, the transmission assembly 34 employs a transmission gearbox.
[0073] In this embodiment, see Figure 5 and Figure 7 The bracket 21 includes a mounting plate 211 and a mounting box 212. The mounting box 212 has a first opening (not shown in the figure). The second rotary drive component 31 is located inside the mounting box 212. The mounting plate 211 is detachably connected to the mounting box 212 and can seal the first opening to prevent welding slag generated during the welding process from entering the mounting box 212 and affecting the use of the second rotary drive component 31. The mounting plate 211 has a second opening 2111, and the connecting gear 32 is rotatably inserted through the second opening 2111 to mesh with the rack.
[0074] Specifically, see Figure 1 and Figure 7 The mounting plate 211 is provided with a mounting groove 2112 that communicates with the second opening 2111. The transmission component 34 is movably installed in the mounting groove 2112 along the radial direction of the pipe pile 100, driving the transmission component 34 to move. The transmission component 34 can drive the connecting gear 32 to move together, so as to further adjust the distance between the connecting gear 32 and the flexible track body 11, adapt to the flexible track body 11 with different degrees of curvature, and further improve the versatility of the pipe pile welding equipment.
[0075] In this embodiment, see Figure 7 and Figure 8 The flexible track body 11 is provided with multiple square holes 1111. The multiple square holes 1111 are arranged at intervals along the extension direction of the flexible track body 11. The multiple square holes 1111 are the tooth grooves of the rack. The connecting gear 32 meshes with the multiple square holes 1111.
[0076] See Figure 1 , Figure 7 and Figure 8 The flexible track body 11 has square holes 1111 on both the upper and lower sides. When the connecting gear 32 meshes with the multiple square holes 1111 on the upper side, the working mechanism 4 can be located above the flexible track body 11. When the connecting gear 32 meshes with the multiple square holes 1111 on the lower side, the working mechanism 4 can be located below the flexible track body 11. This allows workers to adapt the positions of the flexible track body 11 and the working mechanism 4 according to the specific construction conditions, ensuring that the working mechanism 4 can perform operations at the joint of the two pipe piles 100.
[0077] In an optional embodiment, see [link to relevant documentation] Figure 1 and Figure 8 The track mechanism 1 also includes a plurality of first pushing members 12 disposed on the flexible track body 11. The plurality of first pushing members 12 are arranged at intervals along the extension direction of the flexible track body 11. The first pushing members 12 can abut against the outer wall of the pipe pile 100 to improve the stability of the flexible track body 11 installed on the pipe pile 100.
[0078] In this embodiment, see Figure 1 and Figure 8 The first pushing member 12 includes a pushing rod 121 and a flexible pad 122. One end of the pushing rod 121 is connected to the flexible track body 11, and the other end is connected to the flexible pad 122. The flexible pad 122 can abut against the outer wall of the pipe pile 100. The flexible pad 122 has a certain degree of flexibility, which can prevent damage to the pipe pile 100 when it abuts against the pipe pile 100, thus ensuring the performance of the pipe pile 100.
[0079] For example, the push rod 121 is made of aluminum profile and the flexible pad 122 is made of rubber.
[0080] In another alternative embodiment, see [link to relevant documentation]. Figure 1 and Figure 8 The track mechanism 1 also includes a plurality of second pushing members 13 disposed on the flexible track body 11. The plurality of second pushing members 13 are arranged at intervals along the extension direction of the flexible track body 11. The second pushing members 13 can abut against the outer wall of the pipe pile 100, and the extension length of the second pushing members 13 is adjustable. When the flexible track body 11 is installed on the pipe pile 100, the extension length of the second pushing members 13 is adjusted so that the second pushing members 13 can abut against the outer wall of the pipe pile 100 of different specifications. This ensures the stability of the flexible track body 11 on the pipe pile 100 while also improving the versatility of the flexible track body 11.
[0081] For example, the second pusher 13 is a cylinder.
[0082] In another alternative embodiment, see [link to relevant documentation]. Figure 8 The flexible track body 11 is equipped with multiple first pushing members 12 and multiple second pushing members 13.
[0083] Optionally, see Figure 1 and Figure 8 The flexible track body 11 includes multiple arc-shaped track plates 111 and multiple connecting plates 112. The multiple arc-shaped track plates 111 are continuously arranged along the circumference of the pipe pile 100, and the ends of any two adjacent arc-shaped track plates 111 are spliced together. A connecting plate 112 is provided at the splice point of any two adjacent arc-shaped track plates 111. One end of the connecting plate 112 is detachably connected to one of the two adjacent arc-shaped track plates 111, and the other end is detachably connected to the other of the two adjacent arc-shaped track plates 111. This arrangement allows the flexible track body 11 to adjust its extension length by adjusting the number of arc-shaped track plates 111 to accommodate pipe piles 100 of different specifications. The splicing of the ends of two adjacent arc-shaped track plates 111 ensures that the surface of the flexible track body 11 remains flat, avoiding interference with the meshing of the connecting gear 32 and the square hole 1111.
[0084] For example, the connecting plate 112 is detachably connected to the arc-shaped track plate 111 by bolts.
[0085] For example, both the curved track plate 111 and the connecting plate 112 are made of soft steel plate.
[0086] For example, see Figure 8 There are two curved track plates 111, and their cross-sectional shape is semi-circular.
[0087] Optionally, see Figure 1 and Figure 9The pipe pile welding equipment also includes a working drive mechanism 5, which includes a first drive component 51, a second drive component 52, a third drive component 53, a first base 54, and a second base 55. The first drive component 51 is mounted on the bracket 21, the second drive component 52 is mounted on the first base 54, and the third drive component 53 and the working mechanism 4 are both mounted on the second base 55. The output end of the first drive component 51 is connected to the first base 54 and is used to drive the first base 54 to move the second drive component 52 along the axial direction of the pipe pile 100. The output end of the second drive component 52 is connected to the second base 55 and is used to drive the second base 55 to move the working mechanism 4 along the radial direction of the pipe pile 100. The output end of the third drive component 53 is connected to the welding torch 41 and is used to drive the welding torch 41 to swing up and down. By driving the working mechanism 4 to move axially along the pipe pile 100, the welding torch 41 and the inspection piece 42 can be moved to the connection point of the two pipe pile sections 100 for operation; by driving the working mechanism 4 to move radially along the pipe pile 100, the distance between the welding torch 41 and the inspection piece 42 and the pipe pile 100 can be adjusted to ensure that the welding torch 41 and the inspection piece 42 can be operated on the pipe pile 100; when welding, driving the welding torch 41 to swing up and down helps to optimize the weld formation, control the heat input and ensure the welding quality.
[0088] Specifically, see Figure 1 and Figure 9The first drive assembly 51 includes a third rotary drive member 511, a first guide shaft (not shown in the figure), and a first lead screw 512. Both the first guide shaft and the first lead screw 512 extend along the axial direction of the pipe pile 100. The first base 54 is slidably disposed on the first guide shaft. The first lead screw 512 is threadedly engaged with the first base 54. The third rotary drive member 511 is disposed on the bracket 21. The output end of the third rotary drive member 511 is connected to the first lead screw 512 and is used to drive the first lead screw 512 to rotate. The first lead screw 512 drives the first base 54 to slide along the axial direction of the first guide shaft. The first base 54 drives the second drive assembly 52 and the second base 55 to move along the axial direction of the pipe pile 100. The mounting base 43 of the working mechanism 4 is disposed on the second base 55. The second drive assembly 52 includes a fourth rotary drive member 521, a second guide shaft 522, and a second lead screw 523. Both the second guide shaft 522 and the second lead screw 523 extend radially along the pipe pile 100. The second base 55 is slidably disposed on the second guide shaft 522. The second lead screw 523 is threadedly engaged with the second base 55. The fourth rotary drive member 521 is disposed on the first base 54. The output end of the fourth rotary drive member 521 is connected to the second lead screw 523 and is used to drive the second lead screw 523 to rotate. The second lead screw 523 drives the second base 55 to slide axially along the second guide shaft 522. The second base 55 drives the third drive assembly 53 and the mounting base 43 to move radially along the pipe pile 100. The mounting base 43 drives the welding torch 41 and the detection piece 42 to move. The third drive assembly 53 includes a fifth rotary drive and a swing transmission. The output end of the fifth rotary drive is connected to the welding torch 41 through the swing transmission. The swing transmission adopts a swing gearbox, which can convert the rotational action output by the fifth rotary drive into an up-and-down swinging action and output it to the welding torch 41 to realize the up-and-down swinging of the welding torch 41.
[0089] For example, see Figure 9 The third rotary drive component 511 employs a hexagonal operating head, which is welded to the first lead screw 512. Turning the hexagonal operating head drives the first lead screw 512 to rotate. The mounting box 212 of the bracket 21 has a through hole through which the first lead screw 512 passes, and the hexagonal operating head is located below the bracket 21. In other embodiments, the third rotary drive component 511 is a motor.
[0090] For example, the fourth rotary drive 521 is a motor, which is connected to the second lead screw 523 via a coupling.
[0091] Optionally, the pipe pile welding equipment also includes a control mechanism, which is communicatively connected to the walking drive mechanism 3, the working drive mechanism 5 and the working mechanism 4, and is used to control the opening and closing of the walking drive mechanism 3, the working drive mechanism 5 and the working mechanism 4, thereby improving the automation level of pipe pile 100 docking and improving the efficiency of pipe pile 100 docking.
[0092] Specifically, the control mechanism includes a controller and a remote controller. The controller is communicatively connected to the remote controller, the second rotary drive component 31, the work drive mechanism 5, the welding machine, and the inspection component 42. The operator can control the commands executed by the controller through the remote controller, and the controller can control the opening and closing of the second rotary drive component 31, the work drive mechanism 5, the welding machine, and the inspection component 42.
