[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figures 1 - 3, an embodiment provided by the present utility model: an air cooler tube box welding device, including a fixed rod 1. The fixed rod 1 can support and limit that the tube plate welder 2 can only slide vertically relative to the fixed rod 1. A chute 6 is opened at the side end of the fixed rod 1. The chute 6 is T-shaped, which can limit the tube plate welder 2 to only slide vertically, and the chute 6 can be clamped with a pull rod 7 to make the tube plate welder 2 relatively fixed, facilitating movement and welding. In this way, it is not necessary to hold it all the time, increasing the simplicity of operation. A T-shaped block 9 is slidably connected inside the chute 6. The T-shaped block 9 is restricted by the chute 6 so that the tube plate welder 2 can only slide vertically relative to it. A pull rod 7 is elastically connected inside the T-shaped block 9 through a first spring 10. The pull rod 7 is Z-shaped and can slide towards the middle to release the limit of the tube plate welder 2, and can slide up and down to weld and fix the pipes installed on the air cooler tube box. The outside of the pull rod 7 is slidably connected inside the chute 6. One end of the first spring 10 is fixedly connected to the middle inside of the T-shaped block 9. When the first spring 10 is compressed, the rear part of the pull rod 7 can be fixed inside the chute 6. The other end of the first spring 10 is fixedly connected to the rear side of the pull rod 7.

[0034] Referring to Figure 1 , Figure 3 and Figure 4 , a fixed column 8 is slidably connected to the rear part of the pull rod 7. The fixed column 8 restricts the pull rod 7 to only slide horizontally in a straight line within a fixed distance. Both ends of the fixed column 8 are fixedly connected to the middle inside of the T-shaped block 9. A tube plate welder 2 is fixedly connected to the side end of the T-shaped block 9. The tube plate welder 2 can slide into the inside of the pipe to weld and fix the air cooler tube box. Both ends of the tube plate welder 2 are in contact with the side end of the fixed rod 1. An connecting rod 3 is fixedly connected to the upper part of the fixed rod 1. The connecting rod 3 can drive the fixed rod 1 to slide horizontally back and forth so that the tube plate welder 2 can slide into or out of the pipe, and there is no need for repeated positioning. The outside of the connecting rod 3 is slidably connected inside the positioning groove 4. A positioning block 14 is fixedly connected to the right part of the connecting rod 3. The positioning block 14 restricts the connecting rod 3 to only slide horizontally in a straight line within a fixed distance relative to the positioning groove 4, and can keep the fixed rod 1 in a vertical state. The outside of the positioning block 14 is slidably connected to the positioning groove 4. A clamping assembly is fixedly connected to the lower part of the positioning groove 4.

[0035] Referring to Figures 4 - 6, the clamping assembly includes a U-shaped groove 5. The U-shaped groove 5 can restrict the clamping rod 11 to slide only horizontally and linearly within a fixed distance. The upper part of the U-shaped groove 5 is fixedly connected to the lower part of the positioning groove 4. The U-shaped groove 5 can keep the positioning groove 4 relatively fixed, and can keep the positions of the two end fixing rods 1 fixed. A clamping rod 11 is slidably connected inside the U-shaped groove 5. The horizontal and linear sliding of the clamping rod 11 can clamp the upper ends of air-cooled condenser tube boxes of different sizes. A cylinder 13 is fixedly connected inside the lower end of the clamping rod 11. The cylinder 13 restricts the rotation column 12 to rotate only on the side of the lower end of the clamping rod 11. The outside of the cylinder 13 is rotatably connected to a rotation column 12. The outside of the rotation column 12 is rotatably connected inside the lower end of the clamping rod 11. Through the rotation column 12, the whole device can slide horizontally and linearly, so that the whole device can be driven to slide to weld pipes at different positions, and the movement and positioning are quick and convenient.

[0036] Working principle: Sliding the clamping rod 11 towards both ends can enable the clamping rod 11 to fixedly install the whole device on the upper ends of air-cooled condenser tube boxes of different sizes. At this time, the side end of the rotation column 12 is in contact with the outer wall of the air-cooled condenser tube box. Slide the pull rod 7 towards the middle. The pull rod 7 slides out of the inside of the chute 6 and compresses the first spring 10. Subsequently, the fixing rod 1 can be slid horizontally. The fixing rod 1 drives the T-shaped block 9 to slide. The sliding of the T-shaped block 9 drives the pull rod 7 and the tube sheet welding machine 2 to slide, so that the side end of the tube sheet welding machine 2 slides into the inside of the pipe, enabling the tube sheet welding machine 2 to weld and fix the pipe. Then slide the fixing rod 1 and the tube sheet welding machine 2 horizontally back to their original positions, and the tube sheet welding machine 2 can be slid up and down to slide the tube sheet welding machine 2 to different heights to weld and fix pipes at different heights. After a group of vertical pipes are welded and fixed, the whole device can be slid horizontally. The rotation of the rotation column 12 can enable the whole device to slide horizontally, so that the tube sheet welding machine 2 slides to different positions to weld and fix the pipes. When moving or no longer welding, the pull rod 7 can be released to slide into the inside of the chute 6 under the pulling of the first spring 10 to keep the tube sheet welding machine 2 fixed relative to the fixing rod 1.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
