[0016] 2. The welding and fixing device for splicing protective fences used in the civil construction of this wind power project has a base that can be moved quickly via casters, making it easy to move to different positions to fix multiple fences, thus improving the working efficiency of the device. The support plate is in close contact with the ground to support the device, increasing the support area of ​​the device and strengthening the fixing force of the device to the fence, making the welding more stable.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-7One embodiment of the present invention is: a welding and fixing device for splicing protective fences in civil construction of wind power generation projects, comprising a base 1, a linear motor 2 fixedly connected to the bottom inner wall of the base 1, a transmission plate 3 fixedly connected to the moving end of the linear motor 2, a rubber pad 4 fixedly connected to the upper surface of the base 1, a clamping seat 5 fixedly connected to both ends of the transmission plate 3, a clamping seat 6 provided on the upper surface of the rubber pad 4, a gripping device 7 provided on the front and rear sides of the base 1, the gripping device 7 is used to enhance the support of the device and make the welding more stable, a protective device 8 is provided on the front side of the base 1, the protective device 8 is used to reduce the danger generated during welding and improve welding safety, the clamping seats 6 are close to each other and clamp the front and rear sides of the fence to fix the fence and facilitate the welding of the fence by the workers, the fence and the rubber pad 4 abut against each other to enhance the friction between the device and the fence and make the fence more stable during welding, the base 1 includes an adjusting plate 9, the bottom end of the adjusting plate 9 is hinged to the upper surface of the clamping seat 5, and a T-shaped groove 10 is formed in the clamping seat 5. The T-shaped slider 11 is slidably connected to the inner surface of the T-shaped groove 10 on the inner surface of the base 6. The base 1 also includes an insert plate 12, which is fixedly connected to the end of the T-shaped slider 11 away from the adjusting plate 9. The insert plate 12 is used to fix the clamp 6. The clamp frame 13 is fixedly connected to the side of the clamp 5 away from the adjusting plate 9. The clamp frame 13 is used to connect the insert plate 12 and the clamp 5. The clamp groove 14 is opened on the front and rear sides of the base 1. The transmission plate 3 is slidably connected to the inner wall of the base 1. The clamp 5 is slidably connected to the inner wall of the base 1. The clamp 6 and The inner surface of the top of the base 1 is slidably connected, and the top of the clamp 6 and the top of the adjusting plate 9 are hinged. The clamp 6 is placed on the front and rear sides of the base 1, and the clamp 6 then drives the adjusting plate 9 to rotate back and forth and fit against the base 1. At this time, the fence is not blocked by the clamp 6 and the adjusting plate 9, so it is easy to pull the base 1 out from the bottom of the fence, which improves the ease of use of the device. The insert plate 12 is inserted into the card frame 13 to connect and fix the card seat 5 and the clamp 6, which facilitates the clamping of the fence and further improves the ease of use of the device.

[0024] Working principle: Push the base 1 into the bottom of the fence to be welded, start the linear motor 2, the linear motor 2 drives the front and rear transmission plates 3 to move closer together, the transmission plates 3 drive the clamp 5 to slide on the base 1 and move closer together, the clamp 5 then drives the clamp 6 to move closer together and clamp the front and rear sides of the fence, fixing the fence and facilitating welding. After the base 1 is pushed to the bottom of the fence, the fence and the rubber pad 4 abut against each other, increasing the friction between the device and the fence, making the fence more stable during welding. After welding is completed, the linear motor 2 drives the clamp 5 and clamp 6 to move away from each other through the transmission plates 3. At this time, rotate the adjusting plate 9 to make the adjusting plate 9 lie flat on the base 1. At this time, the adjusting plate 9 drives the clamp 6 to lie down. Then, pull the two clamps 6 to the front and rear sides of the base 1 respectively, and place the clamps 6 to the front and rear sides of the base 1. The clamps 6 then drive the adjusting plate 9 to rotate back and forth and fit against the base 1. At this time, the fence is not blocked by the clamps 6 and the adjusting plate 9, so it is easy to pull the base 1 out from the bottom of the fence, which improves the ease of use of the device. When it is necessary to clamp the fence, place the clamps 6 and the adjusting plate 9 back vertically on the card seat 5, and then push the insert plate 12 down. The insert plate 12 drives the T-shaped slider 11 to slide down in the T-shaped slide groove 10, so that the insert plate 12 is finally inserted into the card frame 13, thereby connecting and fixing the card seat 5 and the clamps 6, which facilitates the clamping of the fence and further improves the ease of use of the device.

[0025] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the gripping device 7 includes a caster wheel 71, which is fixedly connected to the lower surface of the base 1. The caster wheel 71 is used to drive the base 1 to move. A support plate 72 is hinged to the front and rear sides of the base 1, and the support plate 72 supports the base 1. A nut 73 is fixedly connected to the upper bottom surface of the support plate 72, and a screw 74 is threaded onto the inner surface of the nut 73. The screw 74 is used to insert into the soil to increase the supporting force of the support plate 72. The base 1 can move quickly through the caster wheel 71, thereby facilitating movement to different positions to fix multiple fences, improving the working efficiency of the device. The ground contact provides support for the device, increasing its support area and strengthening its fixation to the fence, making the welding more stable. The screw 74, through its threaded connection with the nut 73, rotates downwards and inserts into the soil, connecting the entire device to the ground and further enhancing its fixation. The gripping device 7 also includes a locking shaft 75, which is fixedly connected to a short insert rod 76 on the lower inclined surface of the support plate 72. The short insert rod 76 is fixedly connected to the side of the card seat 5 near the inner wall of the base 1. The short insert rod 76 is used to insert the locking shaft 75 and fix the support plate 72. The positioning shaft 77 is fixedly connected to the upper inclined surface of the support plate 72. The rear connecting plate 78 is fixedly connected... A long insert rod 79 is fixedly connected to the side surface of the retaining seat 5 located inside the rear side of the base 1. A long insert rod 711 is fixedly connected to the front side of the rear connecting plate 78. A locking shaft 75 abuts against the front and rear sides of the base 1. A positioning shaft 77 abuts against the front and rear sides of the base 1. A short insert rod 76 slides through the inner wall of the base 1 and extends out of the front and rear sides of the base 1. A long insert rod 79 slides through the rear side of the front connecting plate 710 and extends out of the front side of the front connecting plate 710. A long insert rod 711 slides through the front side of the rear connecting plate 78 and extends out of the rear side of the rear connecting plate 78. Insert rod 79 slides through the inner wall of base 1 and extends out of the front side of base 1, while long insert rod 711 slides through the inner wall of base 1 and extends out of the rear side of base 1. A torsion spring is provided at the hinge of support plate 72 and base 1. Short insert rod 76 is pulled out from locking shaft 75 and retracted into base 1. When locking shaft 75 loses the locking of short insert rod 76, support plate 72 loses its limit. At this time, the torque of torsion spring drives support plate 72 to rotate rapidly and fit against the ground, lifting support plate 72 upward. When the card holders 5 move away from each other, they drive short insert rod 76 to approach and insert into locking shaft 75, fixing support plate 72 away from the ground. This facilitates moving the device and improves the ease of use of the device.

[0026] Working Principle: The base 1 is pushed, and the base 1 moves quickly via casters 71, facilitating its movement to different positions for fixing multiple fences, thus improving the device's efficiency. When fixing a fence, the casters 71 are locked, and then the support plate 72 is rotated to bring it into contact with the ground, providing support and increasing the support area, thereby enhancing the device's fixing force on the fence and making the welding more stable. After the support plate 72 is in contact with the ground, the screw 74 is rotated. The screw 74, through its threaded connection with the nut 73, rotates downwards and inserts into the soil, connecting the entire device to the ground, further enhancing the device's fixing force. When the linear motor 2 drives the transmission plate 3 and the clamping seat 5 to approach each other, the clamping seat 5 drives the short insertion rod 76 to be pulled out from the locking shaft 75 and retracted into the base 1. The locking shaft 75 loses the locking of the short insertion rod 76, allowing the support plate 72 to... When the limit is lost, the torque of the torsion spring causes the support plate 72 to rotate rapidly and come into contact with the ground. When the card holders 5 approach each other, they cause the rear connecting plate 78 and the front connecting plate 710 to approach each other. The rear connecting plate 78 and the front connecting plate 710 then cause the long insert rod 1 79 and the long insert rod 2 711 to slide inside each other and finally extend out of the front and rear sides of the base 1 and insert into the positioning shaft 77 to fix the support plate 72 to the base 1. After welding is completed, the linear motor 2 drives the transmission plate 3 and the card holder 5 to move away from each other. The card holder 5 causes the rear connecting plate 78 and the front connecting plate 710 to move away from each other. The rear connecting plate 78 and the front connecting plate 710 then cause the long insert rod 1 79 and the long insert rod 2 711 to be pulled out of the positioning shaft 77 and retracted into the base 1. At this time, the support plate 72 is lifted upward. When the card holders 5 continue to move away from each other, they cause the short insert rod 76 to approach and insert into the locking shaft 75, so that the support plate 72 is fixed in a state away from the ground, which facilitates the movement of the device and improves the ease of use of the device.

[0027] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the protective device 8 includes an H-shaped bracket 81, which is fixedly connected to the front side of the base 1. A U-shaped lifting frame 82 is slidably connected to the inner surface of the H-shaped bracket 81. A mounting plate 83 is fixedly connected to the upper surface of the U-shaped lifting frame 82. The mounting plate 83 is used to mount the welding torch. A protective plate frame 84 is fixedly connected to the upper surface of the mounting plate 83. The protective plate frame 84 is used to block the electric arc sparks generated during welding. The mounting plate 83 drives the welding torch to move up and down. The movement of the welding torch is restricted by the H-shaped bracket 81 and the U-shaped lifting frame 82, thereby maintaining stability and improving the accuracy of the overall welding of the fence. It avoids the danger of the welding torch falling due to operational errors when manually holding the welding torch in the air. In addition, during the welding process, the protective plate frame 84 and the side inclined plate 85 can prevent the sparks, arcs and slag spatter generated during welding from causing harm, thus improving the safety of the device. The protective device 8 also includes a side inclined plate 85, which is fixedly connected to the protective plate frame 84. On both sides, a conductive wire 86 is fixedly connected to the front inclined surface of the side inclined plate 85. The side inclined plate 85 is used to block and absorb the electric arc generated during welding. The conductive wire 86 is used to conduct the current formed after the electric arc accumulates. The wire harness 87 is fixedly connected to the upper front surface of the base 1. The wire harness 87 is used to limit the conductive wire 86. The grounding nail 88 is snapped into the inner surface of the screw 74. The grounding nail 88 is used to conduct the current into the ground. An electric cylinder is fixedly connected to the upper middle surface of the H-shaped bracket 81. The free end of the electric cylinder is fixedly connected to the lower top surface of the U-shaped lifting frame 82. The wire harness 87 is snapped into the inner surface of the wire harness 87. The top end of the grounding nail 88 is fixedly connected to the bottom end of the conductive wire 86. The screw 74 drives the grounding nail 88 to insert into the soil, thereby quickly releasing the current into the soil and preventing the current from accumulating around the protective plate frame 84 and causing harm to the workers. This further improves the safety of the device. In addition, the wire harness 87 can bind the conductive wire 86 to the base 1 to prevent the conductive wire 86 from swinging when conducting current.

[0028] Working principle: After the welding gun is installed on the mounting plate 83, the electric cylinder is activated. The electric cylinder drives the U-shaped lifting frame 82 to slide and rise within the H-shaped bracket 81. The H-shaped bracket 81, in turn, drives the welding gun to move up and down via the mounting plate 83, making the welding process more stable. Even though the movement of the welding gun is restricted by the H-shaped bracket 81 and the U-shaped lifting frame 82, it remains stable, improving the accuracy of the overall welding of the fence. This avoids the danger of the welding gun falling due to operational errors when manually holding it in mid-air. Furthermore, during the welding process, the protective plate frame 84 and the side inclined plate 85 can prevent the sparks, arcs, and slag spatter generated during welding from causing harm, thus improving safety. The device is designed for safe use. When the electric arc generated during welding jumps, it is absorbed by the inclined plate 85. The current is then conducted from the inclined plate 85 to the conductive wire 86, and then from the conductive wire 86 to the grounding nail 88. When the support plate 72 rotates and contacts the ground, it drives the screw 74 to rotate circumferentially and insert into the soil. The screw 74 then drives the grounding nail 88 to insert into the soil, thereby quickly releasing the current into the soil and preventing the current from accumulating around the protective plate frame 84 and causing harm to the workers. This further improves the safety of the device. In addition, the wire harness 87 can bind the conductive wire 86 to the base 1 to prevent the conductive wire 86 from swinging when conducting current.
