Description

Technical Field

[0001] The present invention relates to the technical field of production of steel cage for pipe piles, and particularly to a pipe pile rolling machine. Background Art

[0002] As is well known, a pipe pile is a combination of precast concrete material and a steel cage, and is widely used in the construction industry.

[0003] Among them, in the production process of the steel cage, the use of a rolling machine is indispensable. It is an essential equipment for producing the steel cage. For the rolling machine, its wire threading disc plays a role in controlling multiple longitudinal bars constituting the steel cage to be arranged in a circle at intervals in the circumferential direction and preventing the steel cage from being distorted and deformed.

[0004] However, in the pipe pile rolling machine disclosed in Chinese Patent Application No. 202310425800.7, since the conductive disc in its wire threading die is fixedly connected to the conductive shaft, and considering that the inner cavity sizes enclosed by steel cages are different due to different specifications, when facing steel cages of different specifications, the conductive disc in the aforementioned pipe pile rolling machine cannot be applied, and only the corresponding specification conductive disc can be replaced. Moreover, due to the fixed connection between the conductive disc and the conductive shaft, the replacement operation of the conductive disc is very difficult, and the automatic replacement operation of the conductive disc cannot be realized.

[0005] Therefore, there is an urgent need for a pipe pile rolling machine to overcome the above defects. Summary of the Invention

[0006] The purpose of the present invention is to provide a pipe pile rolling machine to achieve the automatic and rapid installation and disassembly of the conductive disc, so as to achieve the purpose of automatic replacement of the conductive disc.

[0007] To achieve the above object, the pipe pile rolling welding machine of the present invention includes a frame, a steel bar threading die, a turntable, a turntable driving motor, a guiding mechanism, a pressing power mechanism, a manipulator, and a controller electrically connected to the turntable driving motor, the pressing power mechanism, and the manipulator respectively. The steel bar threading die includes a steel bar threading die body for multiple steel bars to pass through and arrange the passed steel bars into a ring-shaped steel bar cage, a conductive disc located directly in front of the steel bar threading die body along the steel bar threading direction, a pressing driver located corresponding to the rear of the conductive disc, and a pressing head located corresponding to the front of the conductive disc; the steel bar threading die body is assembled on the frame and passes through the frame; the pressing driver is assembled at the steel bar threading die body, the pressing head is fixedly connected to the output end of the pressing driver, and the pressing head presses the conductive disc onto the steel bar threading die body under the drive of the pressing driver, and a disassembly and assembly passage for the pressing head to pass through is provided on the conductive disc when it is disassembled and assembled. The turntable is rotatably assembled on the frame around the steel bar threading die, and the turntable driving motor is used to drive the turntable to rotate around the steel bar threading die. The guiding mechanism is assembled on the turntable and is used for the welding wire to pass through and be guided, and the welding wire guided by the guiding mechanism can be wound around the ring-shaped steel bar cage during the process of following the turntable to rotate. The pressing power mechanism is assembled on the turntable, and a welding pressing disc is assembled at the output end of the pressing power mechanism, and the welding pressing disc can press the welding wire guided by the guiding mechanism onto the steel bar under the drive of the pressing power mechanism. The manipulator is used for disassembling and assembling the conductive disc, and when the disassembly and assembly passage is aligned with the pressing head, the manipulator makes the grabbed conductive disc slide along the steel bar threading direction over the pressing head and disassemble it from the steel bar threading die body.

[0008] Compared with the prior art, by means of a pressing driver located corresponding to the rear of the conductive disc, a pressing head located corresponding to the front of the conductive disc, and a disassembly and assembly channel opened on the conductive disc for the pressing head to pass through when the conductive disc is disassembled and assembled; therefore, when disassembling the conductive disc, under the grasping of the conductive disc by the manipulator, the pressing head is driven by the pressing driver to move forward to release the pressing on the conductive disc; then, the disassembly and assembly channel of the conductive disc is aligned with the pressing head along the direction of the reinforcing bar. The alignment can be achieved by rotating the conductive disc around its center line by the manipulator to align the disassembly and assembly channel with the pressing head, or the alignment can be achieved by rotating the pressing head. After alignment, the manipulator can slide the grasped conductive disc along the direction of the reinforcing bar over the pressing head and remove it from the main body of the reinforcing bar die, realizing the disassembly operation of the conductive disc. When installing the conductive disc, at this time, the manipulator aligns the disassembly and assembly channel of the grasped conductive disc with the pressing head along the direction of the reinforcing bar; after alignment, the manipulator slides the grasped conductive disc along the direction opposite to the direction of the reinforcing bar over the pressing head and approaches the main body of the reinforcing bar die; then, the disassembly and assembly channel of the conductive disc grasped by the manipulator and the pressing head are misaligned with each other; then, the pressing driver drives the pressing head to move along the direction opposite to the direction of the reinforcing bar, so that the pressing head presses the conductive disc grasped by the manipulator against the main body of the reinforcing bar die, and the pressing head and the main body of the reinforcing bar die jointly clamp the conductive disc, achieving the installation purpose of the conductive disc. Therefore, the pipe pile seam welder of the present invention can realize the automatic and rapid disassembly and assembly of the conductive disc to achieve the purpose of automatic replacement of the conductive disc, completely replacing manual operation and meeting the needs of unmanned operation.

[0031] To explain the technical content and structural features of the present invention in detail, the following further explanations are provided in combination with the implementation modes and accompanied by the drawings.

[0032] Please refer to Figures 1 to 3 , the pipe pile rolling welding machine 100 of the present invention includes a frame 10, a steel bar threading die 20, a turntable 30, a turntable driving motor 40, a guiding mechanism 50, a pressing power mechanism 60, a manipulator 70, and a controller 80 electrically connected to the turntable driving motor 40, the pressing power mechanism 60, and the manipulator 70 respectively. The turntable 30 is rotatably assembled on the frame 10 around the steel bar threading die 20, and the frame 10 provides a supporting function for the rotation of the turntable 30. Optionally, in Figure 2 , as an example, the turntable 30 is assembled at the wall panel 11 of the frame 10, but it is not limited thereto. The turntable driving motor 40 is used to drive the turntable 30 to rotate around the steel bar threading die 20 and provides power for the rotation of the turntable 30. Optionally, in Figure 17 , as an example, the turntable driving motor 40 is installed at the frame 10 and drives the turntable 30 to rotate through chain drive; obviously, in other embodiments, the turntable driving motor 40 can also drive the turntable 30 to rotate through gear drive; in addition, the way the turntable driving motor 40 drives the turntable 30 to rotate and the structure of the turntable 30 are already well known in the art. For details, reference can be made to the pipe pile rolling welding machine disclosed in Chinese Patent Application No. 202310425800.7, so it will not be elaborated here.

[0033] The steel bar threading die 20 includes a steel bar threading die main body 21 for multiple steel bars 211 to pass through and arrange the passed steel bars 211 into a circular steel bar cage 210, a conductive disc 22 located directly in front of the steel bar threading die main body 21 along the steel bar threading direction (as indicated by the arrow A), a pressing driver 23 located behind the conductive disc 22 correspondingly, and a pressing head 24 located in front of the conductive disc 22 correspondingly. The steel bar threading die main body 21 is assembled on the frame 10, and the frame 10 provides a supporting function for the steel bar threading die main body 21; the steel bar threading die main body 21 is also penetrated through the frame 10 to prevent the frame 10 from obstructing the steel bars 211 during the steel bar threading operation on the steel bar threading die main body 21. Optionally, in Figure 2 , as an example, the steel bar threading die main body 21 is assembled on the wall panel 11 of the frame 10 and penetrated through the wall panel 11. Obviously, in other embodiments, the steel bar threading die main body 21 is also assembled at other positions of the frame 10, so it is not Figure 2As shown in the figure. The top pressing driver 23 is assembled at the main body 21 of the steel bar piercing die, and the main body 21 of the steel bar piercing die provides support for the top pressing driver 23. The top pressing head 24 is fixedly connected to the output end 231 of the top pressing driver 23. Driven by the top pressing driver 23, the top pressing head 24 presses the conductive disk 22 against the main body 21 of the steel bar piercing die, providing power for the top pressing head 24 to press the conductive disk 22. In addition, a disassembly and assembly channel 221 is provided on the conductive disk 22 for the top pressing head 24 to pass through when the conductive disk 22 is disassembled and assembled, so as to meet the disassembly requirement of the conductive disk 22.

[0034] The guiding mechanism 40 is assembled on the turntable 30 to meet the requirement that the guiding mechanism 40 rotates with the turntable 30; the guiding mechanism 40 is provided for the welding wire to pass through and be guided, so that the welding wire 220 guided by the guiding mechanism 40 can be wound around the annular steel bar cage 210 during the rotation of the guiding mechanism 40 following the turntable 30; since the guiding mechanism 40 is well-known in the art, it will not be described in detail here.

[0035] The top pressing power mechanism 60 is assembled on the turntable 30 to meet the requirement that the top pressing power mechanism 60 rotates with the turntable 30; a welding pressing disk 60a is assembled at the output end 61 of the top pressing power mechanism 60. Driven by the top pressing power mechanism 60, the welding pressing disk 60a can press the welding wire 220 guided by the guiding mechanism 40 against the steel bar 211 to meet the requirement that the welding wire 220 is in close contact with the steel bar 211 during the seam welding process.

[0036] The manipulator 70 is used for disassembling and assembling the conductive disk 22. When the disassembly and assembly channel 221 is aligned with the top pressing head 24, as shown in Figure 14 shown, the manipulator 70 makes the grabbed conductive disk 22 slide along the steel bar piercing direction over the top pressing head 24, so as to remove it from the main body 21 of the steel bar piercing die, as shown in Figure 15 shown. It can be understood that since the installation process of the conductive disk 22 is exactly opposite to the removal process of the conductive disk 22, the installation process of the conductive disk 22 will not be described here temporarily. For details, please refer to the following. More specifically, as follows:

[0037] As Figure 7 , Figure 10 , Figure 12 and Figure 14 shown, the conductive disk 22 can rotate relative to the main body 21 of the steel bar piercing die around its center line C. The manipulator 70 rotates the conductive disk 22 around the center line C, so that the disassembly and assembly channel 221 is aligned with the top pressing head 24, as shown in Figure 14 shown, or makes the disassembly and assembly channel 221 misaligned with the top pressing head 24, as shown in Figure 12As shown, when the conductive disk 22 is misaligned with the pressing head 24 in the disassembly and assembly channel 221, the conductive disk 22 is pressed against the main body 21 of the rib-piercing die by the pressing head 24, so that under the drive of the pressing actuator 23, the main body 21 of the rib-piercing die and the pressing head 24 clamp the conductive disk 22. Additionally, by means of the manipulator 70, the conductive disk 22 is rotated, which can significantly simplify the structure of the rib-piercing die 10. Obviously, in other embodiments, the pressing head 24 can also be rotated relative to the conductive disk 22, so that the pressing head 24 is aligned or misaligned with the disassembly and assembly channel 221. The implementation method is, for example: adding a rotating mechanism between the pressing actuator 23 and the main body 21 of the rib-piercing die, and the rotating mechanism is responsible for the rotation of the pressing actuator 23 and the pressing head 24; for example, the rotating mechanism can be composed of a rotating motor and a mounting seat fixed on the output shaft of the rotating motor. At this time, the rotating motor is installed on the main body 21 of the rib-piercing die, and the pressing actuator 23 is installed at the mounting seat.

[0038] As Figure 2 , Figure 4 , Figure 9 and Figure 10 As shown, the pressing head 24 includes a base portion 241 fixed to the output end 231 of the pressing actuator 23 and a pressing portion 242 protruding laterally from the base portion 241. The pressing portions 242 are two that are spaced apart from each other and arranged in a ring together, so as to ensure the uniformity of the pressing force applied by the pressing head 24 to the conductive disk 22, thereby ensuring that the conductive disk 22 is more stably and reliably clamped by the pressing head 24 and the main body 21 of the rib-piercing die; obviously, in other embodiments, the number of the pressing portions 242 can also be one, three or four, etc., so it is not limited by Figure 2 , Figure 4 , Figure 9 and Figure 10 shown. Correspondingly, in combination with Figure 7 and Figure 8, the installation and disassembly passage 221 includes a main passage 2211 for the base portion 241 to pass through and a secondary passage 2212 for the pressing portion 242 to pass through. The secondary passage 2212 communicates with the main passage 2211 laterally. More specifically, when there are two pressing portions 242, the central angle between the two pressing portions 242 at this time is 180 degrees. When there are three or more pressing portions 242, the central angle between any two adjacent pressing portions 242 is equal, that is, this central angle is obtained by dividing 360 degrees by the number of pressing portions 242. Additionally, the base portion 241 is an annular body sleeved on the output end 231 of the pressing driver 23, the pressing portion 242 is a sector-shaped annular body, the main passage 2211 is a circular passage, and the secondary passage 2212 is a sector-shaped annular passage; this is to facilitate the manufacturing and processing of the installation and disassembly passage 221 on the conductive disk 22 and the manufacturing of the pressing head 24, and is more conducive to the quick installation and disassembly operation between the pressing head 24 and the conductive disk 22. Among them, regarding the relationship between the installation and disassembly passage 221 and the pressing head 24, it is not required that the shape of the installation and disassembly passage 221 is consistent with the shape of the pressing head 24, as long as the installation and disassembly passage 221 can allow the pressing head 24 to pass through and enable the pressing head 24 to press the conductive disk 22 when it is misaligned with the installation and disassembly passage 221. For example, the installation and disassembly passage 221 in Figure 8 can be deformed into Figure 8 the square passage surrounded by the dashed line.

[0039] As Figures 4 to 6 shown, the rib-piercing die body 21 includes a conductive shaft 211 and rib-piercing disks 212 and fixing plates 213 that each allow a steel bar 211 to pass through and are arranged at intervals along the rib-piercing direction. The rib-piercing disk 212 is located directly behind the conductive disk 22, the fixing plate 213 is located directly behind the rib-piercing disk 212, the conductive shaft 211, the rib-piercing disk 212, and the fixing plate 213 are fixed together, and the conductive shaft 211 also passes through both the fixing plate 213 and the rib-piercing disk 212. The pressing driver 23 is located directly behind the fixing plate 213, and the output end 231 of the pressing driver 23 also passes through the conductive shaft 211, so that the output end 231 of the pressing driver 23 extends from the inside of the conductive shaft 211, effectively preventing the output end 231 of the pressing driver 23 from obstructing the steel bar 211 passing through the rib-piercing disk 212 and the fixing plate 213. Specifically, in combination with Figure 5 and Figure 6 , as an example, the pressing driver 23 is located directly behind the conductive shaft 211. This design arranges the pressing driver 23 at a position aligned with the central position of the rib-piercing die body 21, more effectively avoiding the pressing driver 23 from obstructing the rib-piercing operation of the steel bar 211. Optionally, as an example, the pressing driver 23 can be fixed to the conductive shaft 211. Additionally, the rib-piercing die body 21 is assembled and connected to the frame 10 through its fixing plate 213. For example, the pressing driver 23 is a cylinder, a hydraulic cylinder, or an electric push rod.

[0040] As shown Figure 11 in the figure, the manipulator 70 includes a multi-axis transfer mechanism 71 located beside the frame 10, a grasping mechanism 72 for grasping the conductive disc 22, and a rotating mechanism 73 for driving the grasping mechanism 72 to rotate. The rotating mechanism 73 is assembled between the grasping mechanism 72 and the multi-axis transfer mechanism 71. Here, the multi-axis transfer mechanism 71 refers to a transfer mechanism with two or more axes. Among them, with the help of the grasping mechanism 72, it is used to grasp the conductive disc 22; with the help of the rotating mechanism 73, the conductive disc 22 grasped by the grasping mechanism 72 can rotate around its center line C to meet the need of aligning or misaligning the installation and disassembly channel 221 and the pressing head 24 along the wire-passing direction; with the help of the multi-axis transfer mechanism 71, it is used to drive the rotating mechanism 73 and the grasping mechanism 71 to perform multi-axis movement relative to the frame 10 to meet the movement need of removing or installing the conductive disc 22.

[0041] As shown Figure 2 , Figure 16 and Figure 18 in the figure, the pressing power mechanism 60 includes a power cylinder 62, an electromagnetic control valve 63, and a gas storage container 64 with an inflation nozzle 641. The electromagnetic control valve 63 controls the on-off between the gas storage container 64 and the power cylinder 62, so as to correspondingly control the power cylinder 62 to drive the welding pressing disc 60a to perform the movement of pressing or loosening the welding wire 220. Specifically, in Figure 2 , Figure 16 and Figure 18Among them, as an example, the output end 61 of the top pressing power mechanism 60 is a pivot plate hinged to the turntable 30, and the welding pressing plate 60a is fixed to the pivot plate 61. At this time, the cylinder body and the piston rod in the power cylinder 62 are respectively hinged to the turntable 30, so as to realize that the power cylinder 62 drives the pivot plate 61 together with the welding pressing plate 60a to move in a swinging manner to press or release the pressing of the welding wire 220. Therefore, the space required for the welding pressing plate 60a during movement is smaller. In addition, a pressure sensor 65 for detecting the internal pressure of the gas storage container 64 is provided on the gas storage container 64, and the pressure sensor 65 is electrically connected to the controller 80; by means of the pressure sensor 65, when the pressure in the gas storage container 64 is lower than the preset low pressure value, a signal is fed back to the controller 80, and the controller 80 controls the automatic inflation mechanism 90 described below to inflate the gas storage container 64; and when the inflation pressure of the gas storage container 64 reaches the preset high pressure value, a signal is fed back to the controller 80, and the controller 80 causes the automatic inflation mechanism 90 to stop the inflation operation of the gas storage container 64. That is to say, the controller 80 controls the automatic inflation mechanism 90 to automatically inflate the gas storage container 64 in cooperation with the pressure sensor 65. For example, the electric control valve 63 is a solenoid valve, such as a three-position two-way solenoid valve, to meet the movement requirements of the power cylinder 62 to drive the welding pressing plate 60a to press or release the pressing of the welding wire 220; in addition, for how the electric control valve 63 is energized, reference can be made to the method disclosed in Chinese Patent Application No. 202111166541.8.

[0042] As Figure 2 and Figure 16 shown, when the top pressing power mechanism 60 includes structures such as the power cylinder 62, at this time, the pipe pile rolling machine 100 of the present invention further includes an automatic inflation mechanism 90 electrically connected to the controller 80. The automatic inflation mechanism 90 includes an inflation head 91, a movement driver 92 for driving the inflation head 91 to move, an origin positioning driver 93 assembled on the frame 10, an origin positioning member 94 assembled on the output end 931 of the origin positioning driver 93, and an origin matching member 95 assembled on the turntable 30. The origin matching member 95 protrudes from the outer periphery 31 of the turntable 30, so as to facilitate the abutting and positioning of the origin matching member 95 and the origin positioning member 94; the origin matching member 95 also rotates relative to the frame 10 following the turntable 30. The origin positioning member 94 can be switched at least between the initial position as Figure 21a shown and the positioning position as Figure 21b shown under the drive of the origin positioning driver 93. When the origin positioning member 94 is in the positioning position as Figure 21b shown, it moves to the rotation path 953 (see Figure 21b ) of the origin matching member 95. At this time, the origin positioning member 94 can abut and position with the origin matching member 95 that rotates following the turntable 30. The positioned state is shown in Figure 21cAs shown. After the origin positioning member 94 abuts and positions with the origin matching member 95, the inflation head 91 is configured such that its movement path passes through the inflation nozzle 641, so that after the origin positioning member 94 abuts and positions with the origin matching member 95, the inflation head 91 can move to a position where it is correctly engaged with the inflation nozzle 641, to meet the need for the gas source where the inflation head 91 is located to inflate the gas storage container 64. When the gas storage container 64 is filled to the required capacity, the inflation head 91 is driven by the movement driver 92 to move away from the inflation nozzle 641 and reset, and the origin positioning driver 93 drives the origin positioning member 94 to move away from the origin matching member 95 and switch to the initial position, so as to provide an avoidance function for the rotation of the turntable 30, to meet the need for continuous seam welding. Specifically, in Figure 16 and Figure 17 as an example, the inflation head 91 is fixedly connected to the output end of the movement driver 92, but not limited thereto. Additionally, for a more detailed structure of the automatic inflation mechanism 90, see the following description.

[0043] As Figure 16 and Figures 18 to 20 shown, a matching groove 951 located outside the turntable 30 is provided on the origin matching member 95, and a positioning profile 941 matching the matching groove 951 is provided on the origin positioning member 94. The origin positioning member 94 is positioned with the origin matching member 95 by means of the cooperation of the positioning profile 941 and the matching groove 951; such a design makes the abutting and positioning between the origin positioning member 94 and the origin matching member 95 more reliable. Specifically, in Figure 16 and Figures 18 to 20 as an example, an inclined structure 952 is further provided on the origin matching member 95. The inclined structure 952 is connected to the side of the matching groove 951 away from the outer peripheral edge 31 of the turntable 30. The inclined structure 652 extends obliquely in a direction away from the matching groove 951 and towards the positioning profile 941, so as to use the inclined structure 952 to guide the positioning profile 941 into the matching groove 951, thereby making the abutting and positioning between the origin positioning member 94 and the origin matching member 95 smoother and more reliable. More specifically, in Figure 18 and Figure 20 as an example, the matching groove 951 is an arc groove, and the positioning profile 941 is a circular profile, so as to effectively reduce the frictional resistance when the positioning profile 941 enters the matching groove 951. For example, the origin positioning member 94 is a rolling bearing. Obviously, in other embodiments, the origin positioning member 94 can be a wheel or a round shaft structure; additionally, the origin matching member 95 is a plate structure, but not limited thereto.

[0044] As Figure 16 , Figure 18 , Figure 21a , Figure 21b and Figure 21cAs shown, the origin positioning driver 93 is located above the corresponding turntable 30 so that the origin positioning driver 93 is arranged above the frame 10, thus not increasing the dimensions on both left and right sides of the frame 10. In addition, the origin positioning driver 93 is a cylinder or a hydraulic cylinder with the output end 931 arranged downward, so that the origin positioning member 94 can quickly switch between the initial position and the positioning position. Further, a position sensor 13 electrically connected to the controller 80 is provided beside the origin positioning driver 93, and the position sensor 13 is also arranged opposite to the rotation path 953 of the origin matching member 95; when the origin matching member 95 follows the turntable 30 to the position sensed by the position sensor 13 along the direction indicated by the arrow E, the position sensor 13 feeds back a signal to the controller 80, and the controller 80 controls the turntable drive motor 40 to stop driving the turntable 30, and controls the origin positioning driver 93 to work. The origin positioning driver 93 drives the origin positioning member 94 to move downward to the Figure 21b position shown in the figure, so that the origin positioning member 94 abuts and positions with the origin matching member 95 that rotates along the direction indicated by the arrow E following the turntable 30. The state is shown in Figure 21c and Figure 22 shown in the figure, achieving the purpose of origin positioning of the turntable 30 and the frame 10, and providing accurate positioning for the correct engagement of the inflation head 21 and the inflation nozzle 641. It should be noted that due to inertia, after the turntable drive motor 40 stops driving the turntable 30, the turntable 30 will continue to rotate a certain distance in the original direction at this time, so that the origin matching member 85 on the turntable 30 can correctly abut and position with the origin positioning member 94.

[0045] As Figure 16 and Figure 17 shown in the figure, the motion driver 92 and the gas storage container 64 are separated by the wall panel 11 of the frame 10, so that the motion driver 92 and the gas storage container 64 are arranged on opposite sides with the wall panel 11 as the boundary, making the arrangement of the motion driver 92 and the gas storage container 64 on the frame 10 more reasonable and more compact. It also avoids considering the avoidance of the arrangement position of the motion driver 92 due to the same-side arrangement of the motion driver 92 and the gas storage container 64 on the frame 10, and the increase in the size of the frame 10 due to avoiding the turntable 30. Further, an avoidance channel 111 is opened on the wall panel 11. Optionally, the avoidance channel 111 is a circular channel to facilitate the processing and manufacturing of the avoidance channel 111 on the wall panel 11. Obviously, in other embodiments, the avoidance channel 111 can also be of other shapes, so it is not limited to Figure 16As shown in the figure, when the wall panel 11 is provided with an avoidance channel 111, at this time, the inflation head 91 is placed in the avoidance channel 111, so as to store the inflation head 91 in the avoidance channel 111 when the gas storage container 64 does not need to be inflated. Therefore, the pipe pile rolling machine 100 of the present invention is more concise. For example, the motion driver 92 is a cylinder or a hydraulic cylinder with the output end facing the wall panel 11. On the one hand, it enables the inflation head 91 to quickly move to the position where it engages with the inflation nozzle 641 or the original position away from the inflation nozzle 641. On the other hand, it simplifies the assembly connection structure between the inflation head 91 and the output end.

[0046] As Figure 16 , Figure 18 , Figure 21a , Figure 21b and Figure 21c shown, when the origin positioning driver 93 is located above the turntable 30, at this time, the inflation head 91 and the motion driver 92 are also located above the turntable 30, and the inflation head 91 is also located on the left side of the origin positioning driver 93, so that the space occupied by the origin positioning driver 93 and the inflation head 91 on the wall panel 11 is more reasonable and will not affect the rotation of the turntable 30.

[0047] Among them, in the automatic inflation mechanism 90, by means of the origin positioning driver 93 assembled on the frame 10, the origin positioning member 94 assembled on the output end 931 of the origin positioning driver 93 and the origin matching member 95 assembled on the turntable 30 and protruding from the outer periphery 31 of the turntable 30; therefore, during the origin positioning of the turntable 30 and the frame 10, the origin positioning driver 93 drives the origin positioning member 94 to switch from the initial position as shown in Figure 21a to the positioning position as shown in Figure 21b , so that the origin positioning member 94 in the positioning position moves to the rotation path 953 of the origin matching member 95 and abuts and positions with the origin matching member 95 that follows the turntable 30 and rotates in the direction indicated by the arrow E, as shown in Figure 21c , to realize the origin positioning of the turntable 30 and the frame 10; then, the motion driver 92 drives the inflation head 91 to move towards the inflation nozzle 641 of the gas storage container 64, so that the inflation head 91 is correctly engaged with the inflation nozzle 641; after the engagement, the gas source where the inflation head 91 is located automatically inflates the gas storage container 64. Therefore, the automatic inflation mechanism 90 realizes the automatic inflation of the gas storage container 64, replacing manual inflation to meet the automation requirements of the pipe pile rolling machine 100 of the present invention.

[0048] Compared with the prior art, by means of a pressing driver 23 located at the corresponding rear of the conductive disk 22, a pressing head 24 located at the corresponding front of the conductive disk 22, and a mounting / demounting channel 221 opened on the conductive disk 22 for the pressing head 24 to pass through when the conductive disk 22 is mounted and demounted; therefore, when disassembling the conductive disk 22, under the gripping of the conductive disk 22 by the manipulator 70, the pressing driver 23 drives the pressing head 24 to move forward (i.e., the rib-piercing direction) to release the pressing on the conductive disk 22, and the state is shown in Figure 12 and Figure 13 shown; then, align the mounting / demounting channel 221 of the conductive disk 22 with the pressing head 24 along the rib-piercing direction, and the state is shown in Figure 14 shown. The alignment method can be achieved by rotating the conductive disk 22 by the manipulator 70 around its center line C to align the mounting / demounting channel 221 with the pressing head 24, or by rotating the pressing head 24 to align the mounting / demounting channel 221 with the pressing head 23; after alignment, the manipulator 70 can slide the gripped conductive disk 22 along the rib-piercing direction over the pressing head 24 and remove it from the rib-piercing die body 21, realizing the disassembly operation of the conductive disk 22, and the state is shown in Figure 15 shown. When installing the conductive disk 22, at this time, the manipulator 70 aligns the mounting / demounting channel 221 of the gripped conductive disk 22 with the pressing head 24 along the rib-piercing direction; after alignment, the manipulator 70 slides the gripped conductive disk 22 along the direction opposite to the rib-piercing direction over the pressing head 24 and approaches the rib-piercing die body 21; then, misalign the mounting / demounting channel 221 of the conductive disk 22 gripped by the manipulator 70 with the pressing head 24; then, the pressing driver 23 drives the pressing head 24 to move along the direction opposite to the rib-piercing direction, so that the pressing head 24 presses the conductive disk 22 gripped by the manipulator 70 against the rib-piercing die body 21, and the pressing head 24 and the rib-piercing die body 21 jointly clamp the conductive disk 22 to achieve the installation purpose of the conductive disk 22. Therefore, the pipe pile welding machine 100 of the present invention can realize the automatic and rapid mounting and dismounting of the conductive disk 22 to achieve the purpose of automatic replacement of the conductive disk 22, completely replacing manual operation and meeting the needs of unmanned operation.

[0049] It should be noted that since the manipulator 70 is already well-known in the art, its structure and working principle will not be described in detail here. For the detailed structure of the steel bar piercing die body 111, reference can be made to the pipe pile rolling welder disclosed in Chinese Patent Application No. 202310425800.7. In addition, although the drawings show that the pressing head 24 presses the conductive disk 22 from the central position of the conductive disk 22, and the output end 231 of the pressing driver 23 passes through the central positions of both the conductive shaft 211 and the conductive disk 22; obviously, in other embodiments, the output end 231 of the pressing driver 23 can also pass through other positions of both the steel bar piercing die body 21 and the conductive disk 22. Additionally, the shape of the conductive disk 22 can also be the negative electrode steel bar piercing disk in a new type of multi-specification cage steel bar rapid switching system disclosed in Chinese Patent Application No. 202320504231.0, and the aforementioned installation and disassembly channel 221 can be provided on this negative electrode steel bar piercing disk. Finally, for how the steel bar piercing die 20 and the welding pressing disk 60a are electrified, reference can be made to the method disclosed in Chinese Patent Application No. 202111166541.8; the aforementioned front and back are based on the steel bar piercing direction, the side towards which the steel bar piercing direction faces is the front, and the side opposite to the steel bar piercing direction is the back; and under the control of the controller 80, the pressing driver 23, the turntable driving motor 40, the pressing power mechanism 60, the manipulator 70, and the automatic inflation mechanism 90 work in coordination.

[0050] The above-disclosed are only the preferred examples of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention all fall within the scope covered by the present invention.
