[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] Example 1: A heat exchanger auxiliary installation device includes a mounting shell 1, a screw 6 rotatably connected inside the mounting shell 1, a moving block 7 threadedly connected to the outside of the screw 6, a clamping structure 3 connected to the front side of the moving block 7 through a connecting hole 5 and a screw, a lifting structure 2 connected to the bottom of the outside of the mounting shell 1, a first guide tube 8 connected to the left end of the outside of the mounting shell 1 through a plate and a screw, a push rod 9 slidably connected inside the first guide tube 8, a pushing structure 4 installed at the bottom of the first guide tube 8, and a second guide tube 10 connected to the right end of the outside of the mounting shell 1 through a plate and a screw.

[0031] like Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, the clamping structure 3 includes a connecting frame 301, a connecting plate 302, a bidirectional lead screw 303, an auxiliary rod 304, a clamping plate 305, and a motor 306. The controller (not shown) simultaneously drives the motors 306 on both sides, making the motors 306 on both sides run at the same speed and in the same direction. The output end of the motor 306 is fixedly connected to the bidirectional lead screw 303. The motor 306 drives the bidirectional lead screw 303 to rotate. The two ends of the outer side of the bidirectional lead screw 303 are threadedly connected to the clamping plates 305. The bidirectional lead screw 303 drives the clamping plates 305 on both sides to move closer to each other, thereby clamping and fixing the heat exchange tubes on the inner side of the two clamping plates 305. The motor 306 is driven in the opposite direction, causing the bidirectional lead screw 303 to rotate in the opposite direction, thereby causing the two clamping plates 305 to move away from each other, thereby releasing the heat exchange tubes.

[0032] Connecting plates 302 are fixedly connected to both the left and right ends of the connecting frame 301. Bidirectional screws 303 are rotatably connected inside the connecting plates 302 on both sides, so that the heat exchanger auxiliary installation device has two pairs of clamping plates 305, which can clamp and fix the heat exchange tube at two positions, thereby improving the clamping stability. An auxiliary rod 304 is fixedly connected inside the connecting plate 302. The clamping plate 305 is slidably connected to the outside of the auxiliary rod 304. The auxiliary rod 304 can prevent the clamping plate 305 from rotating with the bidirectional screw 303, and at the same time improve the stability of the clamping plate 305.

[0033] like Figures 1-5As shown, the lifting structure 2 includes a cylinder 201, a fixed plate 202, an outer rod 203, an inner rod 204, and a base plate 205. The outer rod 203 and the cylinder 201 are fixedly installed on the top of the base plate 205. The output end of the cylinder 201 and the top of the inner rod 204 are both fixedly connected to the fixed plate 202. The controller drives the cylinder 201, which in turn drives the fixed plate 202 to move up and down. The top of the fixed plate 202 is connected to the mounting shell 1, which in turn drives the mounting shell 1 to move up and down. The outer side of the mounting shell 1 is connected to a first guide tube 8, a second guide tube 10, and a clamping structure 3, which allows the mounting shell 1 to drive the first guide tube 8, the second guide tube 10, and the clamping structure 3 to move up and down. This makes it easy for the heat exchanger auxiliary installation device to be used for heat exchangers of different heights. The bottom of the outer side of the mounting shell 1 is fixedly connected to the fixed plate 202 by screws, which makes the lifting structure 2 easy to disassemble and assemble, further improving the practicality of the heat exchanger auxiliary installation device.

[0034] like Figure 5 As shown, the movable block 7 has connecting holes 5 spaced at equal intervals. The connecting frame 301 moves back and forth, and the connecting holes 5 are selected at appropriate positions. Screws are used for fixing, thus facilitating fine-tuning of the front and rear positions of the clamping structure 3. Figure 3 and Figure 4 As shown, the mounting shell 1 has connection holes 5 at equal intervals on the left and right side walls. According to the position adjusted by the clamping structure 3, the first guide tube 8 and the second guide tube 10 select the appropriate position of the connection hole 5 and fix it with screws, so as to facilitate the adjustment of the front and rear positions of the first guide tube 8 and the second guide tube 10, and further improve the practicality of the heat exchanger auxiliary installation device.

[0035] Example 2: Figure 1 and Figure 4 As shown, the pushing structure 4 includes an automatic telescopic rod 401 and a push plate 402. The controller drives the automatic telescopic rod 401. The push plate 402 is fixedly connected to the output end of the automatic telescopic rod 401. The automatic telescopic rod 401 drives the push plate 402 to move towards the mounting shell 1. The top of the push plate 402 on the same side as the automatic telescopic rod 401 is fixedly connected to a push rod 9. The push plate 402 drives the push rod 9 to move towards the mounting shell 1. The push rod 9 is slidably connected inside the first guide tube 8, so that the push rod 9 pushes the heat exchange tube inside the first guide tube 8 towards the second guide tube 10, and drives the automatic telescopic rod 401 in the opposite direction. The automatic telescopic rod 401 drives the push plate 402 to move towards the mounting shell 1, so that the push plate 402 pulls the push rod 9 to the leftmost side of the first guide tube 8.

[0036] Working principle: After adjusting the height of the heat exchanger auxiliary installation device and the position of each part as described above, insert the heat exchange tube from the right side of the second guide tube 10 so that one end of the heat exchange tube is inside the first guide tube 8. At this time, the heat exchanger part is located inside the upper and lower clamping plates 305. Use the clamping structure 3 to clamp and fix the heat exchange tube. Place the heat exchanger body on the right side of the second guide tube 10 and align the second guide tube 10 with the hole in the heat exchanger body where the heat exchange tube needs to be inserted.

[0037] The automatic telescopic rod 401 is driven by a screw 6 rotatably connected inside the housing 1. A moving block 7 is threadedly connected to the outside of the screw 6, and a clamping structure 3 is connected to the outside of the moving block 7. The power device that drives the screw 6 rotates the screw 6, causing the moving block 7 to move to the right. The moving block 7 then causes the clamping structure 3 to move to the right. In conjunction with the push of the automatic telescopic rod 401, the heat exchange tube moves towards the heat exchanger body. Driven by the controller, the push rod 9 and the moving block 7 move at the same speed, which facilitates the accurate insertion of the heat exchange tube into the heat exchanger body. It also facilitates the workers to perform welding and other connection work between the heat exchange tube and the heat exchanger body.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
