The support rods 10 are symmetrically arranged along the central cross-section of the C-shaped structure, and the outer ends of the symmetrically arranged support rods 10 are in contact with the outer walls of the welding section 1 1 and the welding section 2 2.

[0051] The bottom end of the door-shaped bracket 8 is fixedly connected to a vertical hydraulic cylinder 11, the piston rod of the vertical hydraulic cylinder 11 is located at the lower end of the vertical hydraulic cylinder 11, and a plurality of key grooves are provided at the outer end of the piston rod. A direction adjustment ring 20 is magnetically attracted to the bottom end of the vertical hydraulic cylinder 11, and the inner wall of the direction adjustment ring 20 is slidably connected to the key groove on the piston rod of the vertical hydraulic cylinder 11, and the top end of the direction adjustment ring 20 is clamped with the bottom end of the vertical hydraulic cylinder 11 through a clamping block.

[0052] The piston rod of the vertical hydraulic cylinder 11 passes through the direction adjustment ring 20 and extends to its lower side. The extended part is fixedly connected to a caster bracket 21. The caster bracket 21 is a long groove structure. The midpoint of the top of the long groove structure is fixedly connected to the bottom end of the vertical hydraulic cylinder 11. The caster bracket 21 is rotatably connected in the long groove structure at one end away from the vertical hydraulic cylinder 11 and is symmetrically arranged along the cross-section of the caster bracket 21.

[0053] A horizontal hydraulic cylinder 13 is fixedly connected between the top of the gate-type bracket 8 and the horizontal adjustment frame 9 via a fixed block. The horizontal hydraulic cylinder 13 is used to adjust the position of the top of the gate-type bracket 8 and the horizontal adjustment frame 9. Both ends of the horizontal adjustment frame 9 are fixedly connected to the corresponding positions of the support rod 10 with latch blocks. A latch 19 is provided in the latch block, and a plurality of latch holes matching the latch 19 are opened on the support rod 10 for fixing the position of the support rod 10.

[0054] The support rods 10 on all the adjustment frames (adjustment frame 1 3, adjustment frame 2 4, adjustment frame 3 5, adjustment frame 4 6) are fixedly connected with an alignment device 12, and the alignment device 12 is electrically connected to the controller. Under the control of the controller, through the cooperation of the laser transmitter and the receiver, it can instruct the adjustment frame 1 3, adjustment frame 2 4, adjustment frame 3 5 and adjustment frame 4 6 to be aligned to the same straight line so that the axes of the welding section 1 and the welding section 2 2 coincide.

[0055] Working process

[0056] Placement and adjustment of the welding sections: Place welding section 1 1 and welding section 2 2 on the ground, place adjustment frame 1 3 and adjustment frame 2 4 at both ends of welding section 1 respectively, place adjustment frame 3 5 and adjustment frame 4 6 at both ends of welding section 2 2, adjust the support rod 10 so that it contacts the bottom ends of welding section 1 1 and welding section 2 2, and then lock the position of the support rod 10 by the latch 19 to ensure that the welding sections are fixed.

[0057] Welding section lifting and alignment: welding section 1 and welding section 2 are lifted by multiple vertical hydraulic cylinders 11. Under the control of the controller, the laser transmitter and receiver of the alignment device 12 are coordinated, and the vertical hydraulic cylinder 11 and the horizontal hydraulic cylinder 13 are adjusted to align the adjustment frame 1 3, the adjustment frame 2 4, the adjustment frame 3 5 and the adjustment frame 4 6 to the same straight line, so that the axes of welding section 1 and welding section 2 are precisely coincident.

[0058] Movement and adjustment of the welding sections. If it is necessary to move welding section 1 and welding section 2, the adjusting frame 1 3, adjusting frame 2 4, adjusting frame 3 5 and adjusting frame 4 6 can be pushed, and the movement can be achieved by rolling the casters on the caster bracket 21 on the ground. When the direction of travel of the casters needs to be adjusted, slide the direction adjustment ring 20 to release the lock on the piston rod of the vertical hydraulic cylinder 11, and rotate the direction of the caster bracket 21 manually or with the help of a tool. After the direction adjustment is completed, lock the direction adjustment ring 20 and the vertical hydraulic cylinder 11 again.

[0059] After the welding operation is adjusted, the welding device 7 is placed between the adjustment frame 2 4 and the adjustment frame 3 5 , and the connecting plate 14 and the door-shaped bracket 8 are locked by the connecting card 18 , and then the welding operation can be started.

[0060] The welding machine for power construction in this embodiment can realize the precise alignment and fixation of welding section 1 and welding section 2 2 through the design of adjusting frame 1 3, adjusting frame 2 4, adjusting frame 3 5 and adjusting frame 4 6, thereby ensuring the stability of welding quality. The precise positioning of the welding section is achieved through the adjustment of the vertical hydraulic cylinder 11 and the horizontal hydraulic cylinder 13. At the same time, the adjustability of the caster bracket 21 improves the flexibility of the equipment, making the welding machine more adaptable at the construction site and more convenient to operate. The alignment device 12 is used in conjunction with the controller to ensure high-precision alignment of the welding sections, thereby improving welding efficiency and effect.

[0061] Example 2

[0062] like Figures 1 to 13 As shown, based on Example 1, this embodiment further describes in detail the specific structure and function of the welding device 7 and its related components in the welding machine, as well as the details of the alignment device 12.

[0063] The welding device 7 is arranged between the adjusting frame 2 4 and the adjusting frame 3 5, and includes a connecting plate 14 symmetrically arranged along a plane connecting the vertical adjusting frame 1 3, the adjusting frame 2 4, the adjusting frame 3 5 and the adjusting frame 4 6 and located between the adjusting frame 2 4 and the adjusting frame 3 5. Both ends of the connecting plate 14 are provided with rotating grooves, and a welding ring 15 is connected between the rotating grooves by rotation, and the outer end of the welding ring 15 is fixedly connected to a gear 16.

[0064] At the upper end of the connecting plate 14, a gear 2 17 is rotatably connected, and the outer end of the gear 2 17 is meshed with the gear 1 16 to realize the rotational drive of the welding ring 15. A rotating shaft is fixedly connected inside the gear 2 17. Both ends of the rotating shaft pass through the connecting plate 14, and a hand wheel is clamped on the penetrating part. The hand wheel is a circular structure and is arranged between the door-shaped bracket 8 and the connecting plate 14, so that the operator can adjust the position and angle of the welding ring 15 manually.

[0065] The connecting plate 14 is fixedly connected to the door-shaped bracket 8 through the connecting card 18 to ensure that the welding device 7 is stable and reliable during operation. A welding gun is fixedly connected to the inner side of the welding ring 15, and the welding gun is electrically connected to an external welding machine through a wire to realize the welding operation.

[0066] In addition, the specific structure of the alignment device 12 is further described in this embodiment. The alignment device 12 includes a positioning block fixedly connected to the outer end of the support rod 10, and a laser emitter and a laser receiver are fixedly connected to the top of the positioning block. The two are located in the same straight line and are fixedly connected through the same alignment tube. The laser emitter and the laser receiver cooperate with each other to detect and indicate the alignment status of welding section 1 and welding section 2.

[0067] Working process

[0068] Installation and adjustment of the welding device: install the welding device 7 between the adjusting frame 2 4 and the adjusting frame 3 5, fix the connecting plate 14 to the door-shaped bracket 8 through the connecting card 18, manually rotate the hand wheel, and drive the rotation of the gear 1 16 through the gear 2 17, so as to adjust the angle of the welding ring 15 and put the welding gun in a suitable welding position.

[0069] Operation of the welding ring. During the welding process, the operator controls the rotation of the welding ring 15 through a hand wheel to ensure that the welding gun can accurately move around the welding points of welding section 1 1 and welding section 2 2 to achieve uniform welding. The welding gun is electrically connected to an external welding machine through a wire, and the welding machine provides the required current and voltage to ensure the stability of the welding process.

[0070] The use of the alignment system is to accurately align welding section 1 and welding section 2 through the alignment device 12 before the welding operation. The laser transmitter emits a laser, which is received by the laser receiver. When the laser beam passes through the alignment tube and accurately shines on the receiver, it means that welding section 1 and welding section 2 are already in the same straight line. Any slight deviation will be detected and an adjustment instruction will be issued through the controller. The operator can further fine-tune the position of the support rod 10 according to the instruction information to ensure the accurate alignment of the welding section.

[0071] This embodiment makes the welding operation more precise and efficient through the detailed design of the welding device 7. The rotating structure of the welding ring 15 and the gear transmission system ensure the stability and uniformity during the welding process. The design of the handwheel enables the operator to flexibly adjust the angle of the welding ring 15 to adapt to different welding requirements.

[0072] The design of the alignment device 12 further improves the alignment accuracy of welding section 1 and welding section 2. The coordinated use of the laser transmitter and the receiver makes the alignment process simple and efficient, reduces human errors in welding, and improves the overall construction quality. The use of the connecting card 18 ensures the stability of the welding device 7 during the welding process and avoids welding quality problems caused by unstable equipment during the welding process.

[0073] In summary, this embodiment has significant beneficial effects in improving welding accuracy, operating convenience and equipment stability, and is suitable for various complex power construction welding scenarios.

[0074] Example 3

[0075] This embodiment, based on Embodiment 1 and Embodiment 2, describes in detail a method for using a welding machine for electric power construction, including the following steps:

[0076] Step S1: Initial placement and erection of welding segments

[0077] First, place welding section 1 1 and welding section 2 2 flat on the ground, place adjusting frame 1 3 and adjusting frame 2 4 at both ends of welding section 1 1, and place adjusting frame 3 5 and adjusting frame 4 6 at both ends of welding section 2 2. The placement positions of these adjusting frames need to ensure the overall stability of the welding section and provide support for subsequent operations.

[0078] Step S2: Adjust the contact between the support rod and the welding section

[0079] The operator manually adjusts the support rod 10 on each adjustment frame according to the specific dimensions of welding section 1 1 and welding section 2 2 so that the end of the support rod 10 contacts the bottom end of the welding section. At this time, the support rod 10 is locked on the adjustment frame by the latch 19 to ensure that the positions of welding section 1 1 and welding section 2 2 are fixed to prevent displacement in subsequent operations.

[0080] Step S3: Lifting and alignment of welding segments

[0081] Use the vertical hydraulic cylinder 11 to gradually lift the welding section 1 and the welding section 2. During the lifting process, the laser transmitter and receiver of the alignment device 12 are used for real-time detection. When the laser emitted by the laser transmitter of one alignment device 12 is received by the receiver of the adjacent alignment device 12, it indicates that the welding section 1 and the welding section 2 are nearly aligned. Through the control of the hydraulic system by the controller, the vertical hydraulic cylinder 11 and the horizontal hydraulic cylinder 13 will automatically adjust the position of each adjustment frame, so that the adjustment frame 1 3, the adjustment frame 2 4, the adjustment frame 3 5 and the adjustment frame 4 6 are finally aligned on the same straight line, thereby ensuring that the axes of the welding section 1 and the welding section 2 coincide.

[0082] Step S4: Movement and direction adjustment of welding section

[0083] According to construction requirements, the positions of welding section 1 and welding section 2 may need to be moved. The operator can move welding section 1 by pushing adjusting frame 1 3 and adjusting frame 2 4, and move welding section 2 2 by pushing adjusting frame 3 5 and adjusting frame 4 6. During the movement, the casters on the caster bracket 21 will make the adjusting frame roll smoothly on the ground. When the rolling direction of the casters needs to be adjusted, the operator slides the direction adjustment ring 20 downward to release the lock of the piston rod of the vertical hydraulic cylinder 11 by the direction adjustment ring 20, and then manually or using a tool to rotate the caster bracket 21 to the desired direction. After the direction is determined, slide the direction adjustment ring 20 upward again to lock the direction adjustment ring 20 with the vertical hydraulic cylinder 11 again to ensure that the casters remain in the desired direction.

[0084] Step S5: Installation and locking of welding device

[0085] After welding section 1 and welding section 2 have been aligned and fixed, the welding device 7 is placed between the adjusting frame 2 4 and the adjusting frame 3 5, and the connecting plate 14 and the door-shaped bracket 8 are firmly locked using the connecting card 18 to ensure that the welding device 7 will not be displaced during the welding process.

[0086] Step S6: Welding operation

[0087] After all the preparations are completed, the operator can start the welding device 7. The welding gun will be driven by the welding ring 15 to rotate and move around the welding point of the welding section to complete the welding operation. During the welding process, the welding gun is electrically connected to the external welding machine to ensure that the current and voltage during the welding process are stable and the welding quality is guaranteed.

[0088] This embodiment provides a detailed operation procedure to ensure that the use of the welding machine for power construction is efficient and reliable.

[0089] Precise welding segment alignment: Through precise control of the vertical hydraulic cylinder 11 and the horizontal hydraulic cylinder 13, combined with the laser indication of the alignment device 12, the welding segment 1 1 and the welding segment 2 2 can be precisely aligned on the same straight line, thereby ensuring the accuracy of the welding point and improving the welding quality.

[0090] Flexible movement and adjustment: The design of the caster bracket 21 and the direction adjustment ring 20 makes the movement and direction adjustment of the welding section more flexible and can adapt to the needs of different construction sites. At the same time, the locking device can ensure the stability of the position after movement and reduce errors.

[0091] Stable welding operation: The fixing and locking structure of the welding device 7 ensures stability during the welding process and avoids welding defects caused by equipment displacement. The design of the manual adjustment of the welding ring 15 enables the operator to accurately adjust the angle of the welding ring 15 according to specific needs, further improving the welding efficiency and quality.

[0092] In summary, this embodiment has significant beneficial effects in ensuring welding accuracy, operational convenience and equipment stability, and is suitable for various complex power construction welding scenarios.

[0093] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
