[0025] The driving motor 4 is used to drive the first lead screw 5 to rotate, so that the first lead screw 5 drives the first slider 6 to move upward in a lead screw transmission manner. The first slider 6 drives the U-shaped plate 8 to move upward accordingly, which can pull the cylindrical gear 13 into engagement with the rack 7, thereby driving the cylindrical gear 13 to rotate. The cylindrical gear 13 drives the second bevel gear 14 to rotate. By means of the meshing of the second bevel gear 14 and the first bevel gear 11, the second lead screw 10 can be driven to rotate, so that the second lead screw 10 drives the fin heat exchanger clamped by the clamping assembly to move upward in a lead screw transmission manner.

The operation of the driving motor 4, the first electric push rod 27 and the second electric push rod 32 can rely on the battery pack installed on this device to provide power;
[0031] The two first electric push rods 27 can be used to pull the two clamping plates 28 closer to each other, so that the two clamping plates 28 firmly clamp the fin heat exchanger. The use of the second reinforcing rod 29 can improve the stability when the clamping plate 28 moves and disperse the load-bearing pressure of the first electric push rod 27. Enabling the second electric push rod 32 can drive the clamped fin heat exchanger to rotate around the first carrier tube 23, thereby adjusting the angle of the fin heat exchanger.
[0032] The working principle of the present utility model:
[0033] During use, first place the fin heat exchanger to be hoisted at the position where multiple auxiliary rollers 18 are located on the base 1. Enable the two first electric push rods 27 to contract, driving the two clamping plates 28 closer to each other, so that the two clamping plates 28 clamp the fin heat exchanger. Then, use multiple universal casters 19 to transfer the position of this device and the fin heat exchanger until it reaches the designated position and stop the continued movement of this device. During the hoisting operation, enable the driving motor 4 to drive the first lead screw 5 to rotate. The first lead screw 5 drives the first slider 6 to move upward in a lead screw drive manner, so that the first slider 6 initially lifts the fin heat exchanger. At the same time, the moving cylindrical gear 13 will mesh with the rack 7, causing the cylindrical gear 13 to rotate around the carrier rod 12. The carrier rod 12 drives the second bevel gear 14 to rotate, so that the second bevel gear 14 drives the first bevel gear 11 to rotate, completing the commutation operation and driving the second lead screw 10 to rotate. The second lead screw 10 drives the second slider 15 to move in a lead screw drive manner, synchronously lifting the fin heat exchanger, so that the upward movement speed of the fin heat exchanger is accelerated and the upward movement range of the fin heat exchanger is increased until the fin heat exchanger is lifted to the designated height;
[0034] If the installation or parking angle of the fin heat exchanger needs to be adjusted, the second electric push rod 32 can be controlled to operate, so that the second electric push rod 32 drives the clamped fin heat exchanger to rotate around the first carrier tube 23 until the fin heat exchanger rotates to the designated angle, and then the fin heat exchanger can be installed or placed at the designated position.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.
