A pulling rope is wound around the wire winding roller 5, and the pulling rope is connected to the outer frame 19 to realize the angle adjustment of the outer frame 19. A protective wheel is arranged on the bottom side of the pulling rope, and the protective wheel is installed on the top plate. A lifting motor is installed in one of the frame blocks 4, one end of the output shaft is connected to the output end of the lifting motor, and a controller is arranged outside the installation base 1.

[0024] Furthermore, the installation base 1 is provided with a sunken groove, and a rotating roller is installed between the inner walls of the groove. The rotating bar 12 is connected to the outside of the rotating roller to limit the rotation of the outer frame 19, so as to achieve the switching between the horizontal and vertical states. A plurality of limiting rods 16 are provided and are fixedly installed on the top surface of the rotating bar 12.

[0025] In this embodiment, a plurality of support rods 11 are arranged inside the outer frame 19. The support rods 11 and the limiting rods 16 correspond to each other. The top end of the limiting rod 16 penetrates through the outer frame 19 and is connected to the bottom end of the support rod 11, so as to realize the lifting adjustment of the outer frame 19. And they are connected by a spring to achieve a shock-absorbing effect during the lifting process. A clamping block 13 is movably connected between the outer frame 19 and the rotating bar 12 to support the outer frame 19 to prevent the outer frame 19 from moving during angle adjustment. An arc-shaped groove is provided on the clamping block 13, and the arc-shaped groove and the limiting rod 16 are adapted to each other. Corresponding limiting holes are provided among the outer frame 19, the clamping block 13 and the rotating bar 12. An insertion rod 14 is inserted into the limiting hole to position the clamping block 13 and facilitate disassembly. A protective strip 18 is arranged on the outer surface of one side of the support rod 11. The heat exchanger body 2 is placed on the protective strip 18 to prevent the equipment from being knocked. Card slots are symmetrically provided on both sides of the outer frame 19. A plurality of limiting blocks 7 are fixedly installed on both sides of the heat exchanger body 2.

Then, the lifting motor is controlled to rotate, and the wire winding roller 5 will start to rotate. The pulling rope will lift one end of the outer frame 19 upward. When the outer frame 19 moves to the vertical state, the lifting motor stops. At this time, the insertion rod 14 is pulled out and the clamping block 13 is disassembled. If the disassembly is difficult, the lifting motor can be controlled to rotate a certain distance again. After disassembly, the lifting motor is controlled to rotate in reverse to support the outer frame 19 to prevent it from tipping over. At this time, the outer frame 19 will move downward. The bottom surface of the outer frame 19 will contact with the rotating bar 12. At the same time, the bottom block 9 will be connected to the limiting groove 17. Finally, the bolt is inserted. During disassembly, the above operations are reversed.
