Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower barrel processing, in particular to a welding support for a wind power tower barrel. Background Technique

[0002] A wind power tower barrel is the tower pole of a wind power generator, which mainly plays a supporting role in a wind power generating set and absorbs the vibration of the set at the same time. When manufacturing the barrel section of a wind power tower barrel, it is usually made by bending a steel plate made of special metal material into a cylindrical shape and then welding the longitudinal connection seams. When welding the longitudinal seams of such a wind power tower barrel section, since the size of the barrel section is generally large, in order to facilitate welding, a welding support is used to assist welding during welding.

[0003] In view of this, Chinese Patent No. CN221231835U proposes a welding support for a wind power tower barrel, which adjusts the positions of a plurality of placing blocks according to the length of the tower barrel so that the plurality of placing blocks are at the equidistant positions of the tower barrel, adjusts the position of the extrusion member to facilitate limiting the tower barrel to prevent it from rolling, evenly shares the weight of the tower barrel through the equidistant positions of the placing blocks, and the adjusting members arranged on both sides drive the pressing member to evenly press the connection part at the top of the tower barrel, increasing the firmness of welding and reducing the probability of fracture;

[0004] However, in the process of using the above technical solution and the existing welding supports for wind power tower barrels, they only have the functions of supporting and position fixing for the barrel section of the wind power tower barrel during welding. During the welding process, since the longitudinal seam of the barrel section is long and the size of the barrel section is large, if the longitudinal seam is not extruded during welding, there will be a phenomenon that the seam is too large to be fully welded, and in serious cases, there may even be a risk of falling off due to the too large area of the later welding area. In view of this, this design scheme proposes a welding support for a wind power tower barrel. Content of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a welding support for a wind power tower barrel to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model proposes a welding support for a wind power tower barrel, which includes a support base and an extrusion mechanism and a welding support mechanism both installed on the top of the support base;

[0007] The extrusion mechanism includes sliders installed on both sides of the top of the bracket base. A connecting frame is connected between the bottoms of the two sliders. Arc-shaped brackets are fixedly provided on the tops of the two sliders. Limiting card slots are opened on the tops of the two arc-shaped brackets. Adjusting plates are inserted through the inner walls of the two limiting card slots. At the middle positions of one ends of the two arc-shaped brackets, first electric telescopic rods are installed, and the output ends of the two first electric telescopic rods are respectively fixedly connected to one side of the two adjusting plates. Extrusion rollers are rotatably provided at one ends of the two adjusting plates. First chutes are opened on both sides of the top of the bracket base, and the outer walls of the two sliders are respectively slidably connected to the inner walls of the two first chutes.

[0008] In one example, a connecting groove is opened in the inner wall of the bracket base, and the inner walls at both ends of the connecting groove are respectively communicated with the inner walls of the two first chutes. The outer wall of the connecting frame is inserted through the inner wall of the connecting groove.

[0009] In one example, a lead screw is rotatably provided in the inner wall of one of the first chutes, and the outer wall of the lead screw is threadedly connected to the inner wall of one of the sliders. A fixed slide bar passes through the inner wall of the other slider in the inner wall of the other first chute. One end of the lead screw passes through the outer wall on one side of the bracket base and is connected to a motor.

A second electric telescopic rod is installed on the top of the support frame. An installation bracket is fixedly provided at the output end of the second electric telescopic rod. A welding torch is installed on one side of the top of the installation bracket.

[0011] In one example, a groove is opened at the middle position of the top of the bracket base. A second chute is opened at the bottom of the inner wall of the groove. Limit blocks are slidably provided at both ends of the inner wall of the second chute. Fixing bolts are threadedly connected to the tops of the two limit blocks, and the outer walls of one ends of the two fixing bolts respectively pass through the inner walls of the two limit blocks and contact the bottom of the inner wall of the second chute.

[0013] The wind power tower welding bracket proposed by the present utility model can bring the following beneficial effects:

[0014] The wind power tower barrel welding bracket, by setting an extrusion mechanism, while the extrusion mechanism moves through the rotation of the lead screw, the electric welding gun above also moves together to weld the barrel section. And during welding, the extrusion roller moves along and squeezes and rolls the welding area, so that the longitudinal gaps of the barrel section are closely fitted together. At this time, welding with the electric welding gun can reduce the welding area, prevent the welding area from cracking and falling off due to too large a welding surface in the later stage, and the whole process is squeezed and fitted along with the movement of the extrusion roller, without manual pressing, improving the welding quality and the convenience of using the device at the same time.

Detailed Embodiment

[0022] In order to more clearly illustrate the overall concept of the present invention, the following is a detailed description by way of example in conjunction with the drawings in the specification.

[0023] The embodiments are as follows:

[0024] The present invention provides as Figures 1-5A wind power tower welding bracket shown in the figure includes a bracket base 1, a pressing mechanism 2 and a welding support mechanism 3 both installed on the top of the bracket base 1;

[0025] The pressing mechanism 2 includes sliders 201 installed on both sides of the top of the bracket base 1. A connecting frame 202 is connected between the bottoms of the two sliders 201. Arc-shaped brackets 203 are fixedly provided on the tops of the two sliders 201. Limiting card slots 204 are opened on the tops of the two arc-shaped brackets 203. Adjusting plates 205 are inserted through the inner walls of the two limiting card slots 204. First electric telescopic rods 206 are installed at the middle positions of one ends of the two arc-shaped brackets 203. The output ends of the two first electric telescopic rods 206 are respectively fixedly connected to one side of the two adjusting plates 205. Pressing rollers 207 are rotatably provided at one ends of the two adjusting plates 205. First chutes 208 are opened on both sides of the top of the bracket base 1. The outer walls of the two sliders 201 are respectively slidably connected to the inner walls of the two first chutes 208. And while the adjusting plate 205 slides in the limiting card slot 204, it is also limited by the limiting card slot 204, making it not easy to fall off the limiting card slot 204. And while the pressing roller 207 slides with the slider 201 and the like, it moves together and rolls on the two side surfaces of the cylinder section. While rolling, due to the pressure applied by the first electric telescopic rod 206, it has a pressing effect on the two sides of the cylinder section, so that the longitudinal gaps of the cylinder section in the rolling area are squeezed together, facilitating welding.

[0026] A connecting groove 209 is opened in the inner wall of the bracket base 1. The inner walls at both ends of the connecting groove 209 are respectively communicated with the inner walls of the two first chutes 208. The outer wall of the connecting frame 202 is inserted through the inner wall of the connecting groove 209. And the outer wall of the connecting frame 202 slides in the connecting groove 209. The outer walls at both ends of it respectively pass through the inner walls at both ends of the connecting groove 209 and are fixedly connected to the bottoms of the two sliders 201;

[0027] Further, a lead screw 210 is rotatably provided on the inner wall of one of the first chutes 208. The outer wall of the lead screw 210 is threadedly connected to the inner wall of one of the sliders 201. A slide bar 211 is fixedly passed through the inner wall of the other slider 201 on the inner wall of the other first chute 208. One end of the lead screw 210 passes through the outer wall on one side of the bracket base 1 and is connected to a motor 212. And while the lead screw 210 rotates to drive the slider 201, the connecting frame 202 and the like to move, the other slider 201 slides on the surface of the slide bar 211, making its overall movement smoother and not easy to deviate and tilt;

[0028] Furthermore, the welding support mechanism 3 includes a support frame 301 fixed to the top of one of the arc-shaped brackets 203. A second electric telescopic rod 302 is installed on the top of the support frame 301. An installation bracket 303 is fixedly provided at the output end of the second electric telescopic rod 302. A welding torch 304 is installed on one side of the top of the installation bracket 303. Before welding, it is necessary to start the second electric telescopic rod 302 to adjust the height of the welding torch 304 to make it contact the gap before welding can be carried out;

[0029] Furthermore, a groove is provided at the middle position of the top of the bracket base 1. A second sliding groove 4 is provided at the bottom of the inner wall of the groove. Two limiting blocks 5 are slidably provided at both ends of the inner wall of the second sliding groove 4. Threaded connections of fixing bolts 6 are provided at the tops of the two limiting blocks 5. And the outer walls of one ends of the two fixing bolts 6 respectively pass through the inner walls of the two limiting blocks 5 and contact the bottom of the inner wall of the second sliding groove 4. Slide the limiting blocks 5 in the second sliding groove 4 according to the length of the cylinder section of the wind power tower barrel so that they abut against the lower edges on both sides of the cylinder section, and fix them with the fixing bolts 6 when in use, so that when the pressing rollers 207 roll and press on its surface, the cylinder section will not shift in position.

[0030] Working principle: When using the wind power tower barrel welding bracket in this design scheme, first, it is necessary to place the cylinder section of the wind power tower barrel formed by extrusion and bending on the top of the bracket base 1. Then slide the limiting blocks 5 at both ends of the second sliding groove 4 so that they are pressed against both sides of the cylinder section and fix them in this position with the fixing bolts 6, thereby fixing the cylinder section. At the same time, the longitudinal gap faces upward. Then start the motor 212 to rotate the lead screw 210. Driven by the lead screw 210 and the slide rod 211 and supported by them, the two sliders 201 slide together in the first sliding grooves 208 on both sides through the connection of the connecting frame 202. Then start the first electric telescopic rod 206 to pull the adjusting plates 205 to move closer to each other until the pressing rollers 207 press against both sides of the outer wall of the cylinder section. Start the second electric telescopic rod 302 to adjust the height of the installation bracket 303 so that the welding torch 304 contacts the gap area of the cylinder section for welding. During this process, the welding torch 304 welds while moving. At the same time, the welding area is pressed by the pressing rollers 207 on both sides to make it fit together fully. After extrusion and fitting, welding is carried out again to reduce the area of the welding gap and make the welding more firm. It is not easy to cause the welding surface to fall off in the later stage, improving the welding quality. And this operation can move and press the cylinder section by the pressing rollers 207 following the movement of the welding torch 304, without the need for manual pressing by the staff, improving the welding quality and the convenience of using the device at the same time.
