For the two pole towers after alignment, it can ensure that the welding part is welded evenly and reduce defects.

[0024] Next, the present application will be described in detail in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0025] As Figures 1 - 6As shown in the figure, an alignment device for tower pole welding, including a welding table 1, support plates 101 arranged on both sides of the top of the welding table 1, support rods 102 installed on the top of the support plates 101, a support block 103 installed on the top of the support rods 102, alignment components arranged on both sides of the support plates 101, and the alignment components include: a fixed block 2, an adjustment groove 201, an alignment plate 203, and an alignment scale 204; a welding component arranged on the top of the welding table 1, and the welding component includes: a support frame 3, a welding machine 301, an electric push rod 302, and a welding head 303.

[0026] Among them, lower clamping plates 104 are installed on both outer sides of the outer end of the support block 103, a clamping block 105 is arranged on the top of the support block 103, upper clamping plates 106 are installed on both outer sides of the outer end of the clamping block 105, fixing screw holes a107 are opened at the tops of the upper clamping plates 106 and the lower clamping plates 104, and fixing screw a108 is threadedly connected inside the fixing screw holes a107.

[0027] When welding tower poles, the clamping block 105 on the top of the support block 103 is removed, and the tower poles are respectively placed on the support blocks 103 on both sides of the top of the welding table 1, so that the two tower poles can be butt-welded. The butt joint of the two tower poles is placed on the support plate 304 outside the support frame 3 to ensure stable support placement of the tower poles. Then, the clamping block 105 is placed on the top of the support block 103 and aligned with it, so that the fixing screw holes a107 of the lower clamping plate 104 and the upper clamping plate 106 are aligned together. At this time, the fixing screw a108 is tightened inside the fixing screw holes a107, and thus the tower poles can be clamped and placed.

[0028] Both the support block 103 and the clamping block 105 are arranged in a semi-circular arc structure. When the tower poles are placed, aligned, and clamped, they can fit with the tower poles, avoiding gaps between the support block 103 and the clamping block 105 and the tower poles, and increasing the stability of the placement of the tower poles.

[0029] Among them, a connecting rod 109 is installed at the bottom of the support block 103, a plug rod 110 is installed at the bottom of the connecting rod 109, a socket 111 is opened at the top of the support rod 102, and fixing screw holes b112 are opened on the outer sides of the support rod 102 and the plug rod 110, and fixing screw b113 is threadedly connected inside the fixing screw holes b112.

[0030] When the supporting block 103 is in use, the insertion rod 110 at the bottom of the connecting rod 109 is inserted into the socket 111 at the top of the supporting rod 102, so that the connecting rod 109 and the supporting rod 102 are butted together. At this time, the fixing screw hole b112 outside the insertion rod 110 is aligned with the fixing screw hole b112 outside the supporting rod 102. The fixing screw b113 is tightened inside the fixing screw hole b112, so that the connecting rod 109 and the supporting rod 102 are stably placed. When it is necessary to replace the supporting block 103 of different sizes, loosen the fixing screw b113 and disassemble the connecting rod 109 and the supporting block 103, and the supporting block 103 and the clamping block 105 with sizes adapted to the pole tower can be replaced, and then the pole towers of different sizes can be clamped and welded.

[0031] Among them, four fixing blocks 2 are installed on both sides of the top of the welding table 1. An adjusting groove 201 is opened inside the fixing block 2. An aligning plate 203 is installed at the outer end of the supporting rod 102. An aligning scale 204 is installed at the outer end of the fixing block 2. Sliders 202 are installed on both sides of the outer end of the supporting plate 101. The sliders 202 are slidably connected with the adjusting groove 201. The aligning plate 203 is located on top of the aligning scale 204.

[0032] After the supporting plate 101, the supporting rod 102 and the supporting block 103 are damaged and need to be replaced, move the supporting plate 101 out from between the two fixing blocks 2, and then replace the new supporting plate 101, supporting rod 102 and supporting block 103 to their original positions. Since the position of the supporting plate 101 on both sides of the top of the welding table 1 will change after the supporting plate 101 is replaced, the supporting rod 102 and the supporting block 103 will also change accordingly. When it is necessary to align and adjust the supporting plate 101, the supporting rod 102 and the supporting block 103 on both sides of the top of the welding table 1, push the supporting plate 101 to move between the two fixing blocks 2, and the sliders 202 on both sides of the outer end of the supporting plate 101 slide inside the adjusting groove 201, thereby driving the supporting rod 102 to move, so that the aligning plate 203 outside the supporting rod 102 can move on top of the aligning scale 204. The scale on the aligning scale 204 is used to assist in moving and adjusting the positions of the supporting plate 101, the supporting rod 102 and the supporting block 103 to ensure that the pole towers are aligned and placed flat after butt joint. This kind of adjustment and alignment method is fast and convenient, and can also reduce the error of the pole tower butt joint, thereby improving the welding quality of the pole tower.

[0033] Among them, a plurality of pin holes 205 are opened on both sides of the top of the four fixing blocks 2, fixing holes 206 are opened on both sides of the top of the slider 202, and a pin rod 207 is fixedly inserted inside the pin hole 205.

[0034] After the support plate 101, the support rod 102, and the support block 103 are moved, adjusted, and aligned, since a plurality of pin holes 205 are provided on both sides of the top of the four fixing blocks 2, the support plate 101 drives the slider 202 to slide inside the adjustment groove 201, so that the slider 202 can be aligned with different positions of the plurality of pin holes 205. At this time, the pin rod 207 is inserted into the pin hole 205 and penetrates into the fixing hole 206. Since the sizes of the pin rod 207, the pin hole 205, and the fixing hole 206 are the same, that is, the pin rod 207 is inserted and fixed with the pin hole 205 and the fixing hole 206, the slider 202 can be locked inside the adjustment groove 201 to prevent the support plate 101, the support rod 102, and the support block 103 from moving positions, ensuring that the pole tower is aligned and welded. When adjustment is required, the pin rod 207 can be directly pulled out from the pin hole 205 and the fixing hole 206.

[0035] Among them, an installation block 208 is installed at the bottom of the alignment scale 204. Limiting holes are provided on both the installation block 208 and the outer side of the fixing block 2. A limiting screw 209 is threadedly connected inside the limiting holes. When the alignment scale 204 is used, the alignment scale 204 is installed on the outer side of the fixing block 2 through the installation block 208. The alignment scale 204 is flush with the fixing block 2. The installation block 208 is close to the outer side of the fixing block 2, so that the limiting holes on the outer sides of the installation block 208 and the fixing block 2 are opposite to each other. At this time, the limiting screw 209 is tightened inside the limiting hole, and then the alignment scale 204 is fixed. When the alignment scale 204 is damaged during use, the limiting screw 209 is directly loosened and taken out, the damaged alignment scale 204 is removed, and after replacing it with a new one, the above installation operation is repeated.

[0036] Among them, a support frame 3 is installed on the top of the welding table 1. A welding machine 301 is installed on the back of the support frame 3. An electric push rod 302 is installed on the top of the support frame 3. A welding head 303 is installed at the bottom of the electric push rod 302. A support plate 304 is installed on the outer side of the support frame 3 facing the welding table 1. The welding head 303 is connected to the welding machine 301 through an electric wire.

[0037] After the support plate 101, the support rod 102, and the support block 103 on both sides of the top of the welding table 1 are adjusted and aligned, the butt joint of the two pole towers can be placed opposite to the welding head 303. At this time, the electric push rod 302 is started to push the welding head 303 to move downward close to the pole tower, that is, the welding head 303 moves down to the butt joint of the two pole towers, and then the welding machine 301 is started to work. Since the welding head 303 is electrically connected to the welding machine 301 through an electric wire, after the welding head 303 is powered on, electrical energy is converted into heat energy, so that the butt joint of the two pole towers is quickly melted by the high heat. After the welding head 303 is removed, the welded part is quickly solidified, and then the two pole towers are welded and fixed together. For the two pole towers after alignment, it can ensure that the welded part is welded evenly and reduce defects.

[0038] The wire connecting the welding head 303 and the welding machine 301 is reserved with sufficient length, facilitating the pulling of the position when the welding head 303 moves up and down without pulling and breaking the wire.

[0039] Among them, a control panel is fixedly installed on one side of the outer end of the welding table 1. A plurality of control buttons are installed on the top of the control panel, and a power cord is installed on the back of the control panel. The welding machine 301 and the electric push rod 302 are connected to the control panel through wires. The length of the power cord is 3 meters, and a plug is installed at the other end of the power cord. The plug can be inserted into the socket in the room to connect to the power supply, enabling the control panel, the welding machine 301, and the electric push rod 302 to be normally powered on and used. The start and stop of the welding machine 301 and the electric push rod 302 can be controlled through the control panel. And for the control program involved in the present utility model, those skilled in the art can all implement it according to the same or similar principles in the prior art. This part is not the innovation of the present utility model.
