DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, purpose and efficacy of the present invention easy to understand, the present invention is further described below in conjunction with specific examples, but the following examples are only preferred embodiments of the present invention, not all. Based on the examples in the embodiments, other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present invention. The experimental methods in the following examples, unless otherwise specified, are conventional methods, and the materials, reagents, etc. used in the following examples, unless otherwise specified, can be obtained from commercial channels. Example

[0024] Please refer to Figure 1 As shown, the present invention provides an automatic welding mobile vehicle for offshore wind power tower production, comprising a support plate 1, with connecting plates 11 fixedly connected to both sides of the support plate 1, and the connecting plates 11 and the bottom surface of the support plate 1 are fixedly connected to limit plates 12, and the bottom surface of the limit plates 12 is provided with walking wheels;

[0025] A first clamping mechanism that moves relatively is provided on both sides of the top surface of the support plate 1, and a second clamping mechanism that moves relatively is provided near the front and back surfaces of the top surface of the support plate 1;

[0026] The top of the connecting plate 11 is fixedly connected to the support column 4, and the top of the support column 4 is fixedly connected to the fixed plate 41. The top surface of the fixed plate 41 is provided with a support mechanism that can be flipped up and down, and the bottom surface of the support mechanism is provided with an adjustment mechanism that can slide left and right. The bottom end of the adjustment mechanism is provided with a limiting mechanism that is telescopically inserted into the tower, and the bottom end of the limiting mechanism is rotatably provided with a welding mechanism for welding the tower.

[0027] In this case, first clamping mechanisms that move relatively are provided on both sides of the top surface of the support plate 1, so that the first clamping mechanism can slide left and right, and second clamping mechanisms are provided on the top surface of the support plate 1 near the front and back, so that the second clamping mechanism can slide back and forth. When in use, the tower can be lifted by a gantry crane, and then the tower is hoisted on the top surface of the support plate 1, so that the tower is located between the first clamping mechanism and the second clamping mechanism. Then, the first clamping mechanism and the second clamping mechanism can be adjusted to clamp the tower at the periphery, and the tower can be moved to ensure the stability of the tower. At this time, the tower is in a vertical state. At this time, the welding mechanism can be flipped to the top of the tower by flipping the support mechanism up and down, and the sliding of the adjustment mechanism can be used. The limiting mechanism can drive the movement of the limiting mechanism, and the limiting mechanism drives the welding mechanism to move, so that the welding mechanism can be located directly above the tower. At this time, the welding mechanism can be inserted into the tower through the driving of the limiting mechanism, and the driving of the welding mechanism by the limiting mechanism can make the welding mechanism slide up and down and resist in the tower to perform vertical welding on the tower. When welding is required at different positions, the position of the welding mechanism can be changed through the rotation of the welding mechanism, so as to facilitate welding at different positions of the tower, improve welding efficiency, and complete automatic welding; at the same time, by arranging walking wheels on the bottom surface of the limiting plate, it is convenient to walk on the road section, so that the tower can be automatically welded during the transportation of the tower, thereby improving work efficiency.

[0028] As a further implementation of this embodiment, Figure 1 and Figure 2 As shown, the first clamping mechanism includes a first screw rod 2, a first slider 21, a first clamping plate 211 and a first servo motor 22. Both sides of the top surface of the support plate 1 are provided with a first sliding groove 13 for the first slider 21 to slide left and right.

[0030] By starting the first servo motor 22, the first screw rod 2 can be driven to rotate, and the first screw rod 2 is threadedly connected to the first slider 21, so that the first slider 21 can drive the first clamping plate 211 to slide, so that the first clamping plate 211 is clamped on both sides of the tower. Then, by starting the driving motor, the second screw rod 3 can be driven to rotate, and the second screw rod 3 is threadedly connected to the second slider 31, so that the second slider 31 can drive the second clamping plate 311 to slide, so that the second clamping plate 311 is clamped on the front and back of the tower. The top surface of the first clamping plate 211 is an arc-shaped structure, so as to horizontally support the tower and act as a mobile cart to transport the tower horizontally.

[0031] As a further implementation of this embodiment, Figure 1 As shown, the supporting mechanism includes a driver 411 and a rotating plate 5. One end of the rotating plate 5 is connected to the top surface of the fixed plate 41 in an upside-down rotating manner. The driver 411 is set on one side of the fixed plate 41 and is used to drive the rotating plate 5 to flip up and down.

[0032] Through the setting of the driver 411, the rotation method of the rotating plate 5 is the same as the method of flipping the upper mold of the mold clamping machine, and the rotating plate 5 can be rotated at an angle of 90 degrees. The rotation of the rotating plate 5 is driven by the driver 411, which is convenient for driving the rotating plate 5 to a vertical state. At this time, it is convenient to hoist the tower between the first clamping plate 211 and the second clamping plate 311 to clamp the tower. Then, the rotating plate 5 can also be driven by the driver 411 to be horizontal, so that the welding mechanism is located above the tower to complete the welding.

The sliding plate 54 drives the support plate 6 to slide, changing the position of the support plate 6 so that the support plate 6 can be adjusted to be directly above the tower.

[0036] As a further implementation of this embodiment, Figure 1 、 Figure 4 and Figure 5 As shown, the limiting mechanism includes a first electric telescopic rod 61, an adjustment plate 7, a second electric telescopic rod 71 and a roller 711.

One end of the second electric telescopic rod 71 is fixedly connected to the roller 711, the roller 711 is rollingly connected to the tower, and the bottom surface of the adjustment plate 7 is rotatably connected to the welding mechanism.
