[0023] Reference Figure 1-Figure 2 The utility model provides an embodiment: an automatic positioning take-over device for a plate heat exchanger, comprising an operating table 1, the four corners of the bottom end of the operating table 1 are fixedly connected with support legs, the bottom of the support legs are fixedly connected with anti-skid pads, firstly, the operating table 1 is placed in a suitable position, the support legs and the anti-skid pads cooperate with each other to increase the stability of the operating table 1, the right side of the operating table 1 is fixedly connected with a support plate, the top of the support plate is equipped with a motor 2, the motor 2 is fixedly installed, the motor 2 is started, the driving end of the motor 2 is fixedly connected with a bidirectional threaded rod 3, the bidirectional threaded rod 3 rotates under the drive of the motor 2, and the other end of the bidirectional threaded rod 3 is rotatably connected to the inner left side of the operating table 1.
[0024] The external threads of the two-way threaded rod 3 are connected to two sliding blocks 4.

The top of the sliding block 4 is rotatably connected to a connecting shaft 5, and the other end of the connecting shaft 5 is rotatably connected to a bottom plate 6. Then the pipe port of the heat exchanger is placed on the top of the bottom plate 6. Square slide grooves 7 are provided on the left and right sides of the top of the operating table 1. The external sliding connection of the connecting shaft 5 is connected to the inner wall of the square slide groove 7. At the same time, the connecting shaft 5 will rotate on the inner wall of the square slide groove 7. Since the limiting sliding blocks 4 of the connecting shaft 5 and the square slide groove 7 will move along the trajectory of the square slide groove 7, when the two connecting shafts 5 move towards each other, the connecting shaft 5 can lift the bottom plate 6 upward, and when the two connecting shafts 5 move away from each other, the bottom plate 6 will reset downward. A placement groove 8 is provided on the top of the operating table 1, which returns to the inner wall of the placement groove 8 and is adjusted according to the required height.
[0025] Reference Figure 1 and Figure 3 , two fixed bins 9 are fixedly connected to the left and right sides of the top of the bottom plate 6, and a buffer assembly is arranged inside the fixed bin 9, which includes a plurality of dampers 18, a plurality of springs 19, a plurality of springs 20 and a plurality of square grooves 21. The top of the damper 18 is fixedly connected to the bottom of the bearing plate 10, one end of the spring 19 is fixedly connected to the bottom of the bearing plate 10, and the other end of the spring 19 is fixedly connected to the bottom of the damper 18. The spring 19 will also be compressed by force, and absorbs external force due to its own elastic characteristics, so as to reduce the shaking of the bearing plate 10 and prevent The diaphragm 18 is in contact with the bottom plate 6, which can reduce the vibration of the bearing plate 10. The spring three 20 is fixedly connected to the inner bottom wall of the fixed bin 9. At this time, the spring three 20 inside the fixed bin 9 will be compressed. The other end of the spring three 20 is fixedly connected to the bottom of the bearing plate 10. A plurality of square grooves 21 are respectively opened on the adjacent side of the fixed bin 9. The bearing plate 10 is forced to slide downward on the inner wall of the square groove 21, thereby realizing the height adjustment of the fixed bin 9. It can flexibly adapt to heat exchangers of different heights and can buffer the fixing ring 11 at the same time to ensure stability during docking.
[0026] A supporting plate 10 is fixedly connected to the adjacent side of the two fixed bins 9, and the front and rear sides of the supporting plate 10 are externally slidably connected to the inner wall of the fixed bin 9. The outside of the supporting plate 10 is externally slidably connected to the inner wall of the square groove 21. A fixing ring 11 is fixedly connected to the top of the supporting plate 10, and then the pipeline is placed into the interior of the fixing ring 11. After the pipeline enters the interior of the fixing ring 11, the fixing ring 11 will be forced to squeeze the supporting plate 10 downward. A plurality of adjustment components are arranged on the top of the fixing ring 11, and the adjustment components include a limit groove 12, a spring 13, a limit plate 14, a connecting column 15 and a rotating shaft 17. The interior of the fixing ring 11 is rotatably connected to a plurality of rotating shafts 17, and the other end of the rotating shaft 17 is rotatably connected to a rubber plate 16. When the pipeline enters the interior of the fixing ring 11, it will first contact the rubber plate 16.
[0027] One side of the rotating shaft 17 is fixedly connected to the other side of the connecting column 15. At this time, the rubber plate 16 will squeeze the connecting column 15 and the rotating shaft 17 inwardly. The limiting groove 12 is opened inside the fixing ring 11, and the spring 13 is arranged inside the limiting groove 12. One end of the spring 13 is fixedly connected to one side of the inner wall of the limiting groove 12. At this time, the spring 13 is compressed inside the limiting groove 12, and the outer side of the limiting plate 14 is slidably connected to the inner wall of the limiting groove 12, so that the limiting plate 14 slides inside the limiting groove 12. One side of the connecting column 15 is fixedly connected to one side of the limiting plate 14, and the other side of the spring 13 is fixedly connected to the side of the limiting plate 14 away from the connecting column 15.

[0028] Working principle: first place the operating table 1 to a suitable position, then place the pipe port of the heat exchanger on the top of the bottom plate 6, then start the motor 2, and the bidirectional threaded rod 3 rotates under the drive of the motor 2. As the bidirectional threaded rod 3 rotates, the sliding block 4 will move outside the bidirectional threaded rod 3, and at the same time, the connecting shaft 5 will rotate on the inner wall of the square slide 7. Since the limiting sliding block 4 of the connecting shaft 5 and the square slide 7 will move along the trajectory of the square slide 7, when the two connecting shafts 5 move towards each other, the connecting shaft 5 can lift the bottom plate 6 upward, and when the two connecting shafts 5 move away from each other, the bottom plate 6 will reset downward. Adjust according to the required height, and then put the pipe into the inside of the fixing ring 11. After the pipe enters the inside of the fixing ring 11, the fixing ring 11 will be forced to squeeze the bearing downward. The carrier plate 10 is forced to slide downward on the inner wall of the square groove 21. At this time, the spring three 20 inside the fixed chamber 9 will be compressed. At the same time, the damper 18 contacts with the bottom plate 6, which can reduce the vibration of the carrier plate 10. The spring two 19 will also be compressed. Due to its own elastic characteristics, it absorbs external forces and can reduce the shaking of the carrier plate 10. When the pipeline enters the interior of the fixed ring 11, it will first contact with the rubber plate 16. At this time, the rubber plate 16 will squeeze the connecting column 15 and the rotating shaft 17 inward, so that the limit plate 14 slides inside the limit groove 12. At this time, the spring one 13 is compressed inside the limit groove 12. When compressed, the spring one 13 will absorb external forces and generate a reaction force on the limit plate 14, so that the rubber plate 16 is in closer contact with the pipeline, making the docking position more accurate.
