[0035] The working principle and beneficial effects of the above technical solution are as follows:
[0036] This utility model discloses a combined telescopic lifting platform for an electrophoretic coating line. The adjusting component 12 drives two sets of lifting components 13 to move laterally towards or away from each other, thereby completing the installation of lifting platforms 11 of different specifications.

[0043] The dual-head motor 21 located on the adjusting seat 20 works, thereby driving the transverse threaded rods 22 mounted on the two output shafts of the dual-head motor 21 to rotate. Since the threads of the two sets of transverse threaded rods 22 are opposite, the transverse threaded rods 22 drive the two sets of transverse blocks 23 to move towards or away from each other respectively. The two sets of lifting components 13 move laterally towards or away from each other, thereby completing the installation of lifting platforms 11 of different specifications.
[0044] In this embodiment, the power assembly 19 includes:

[0057] The working principle and beneficial effects of the above technical solution are as follows:
[0058] In the initial state, the electromagnet device 33 operates, generating magnetism and attracting the magnetic block 32 mounted on the actuating block 30. The spring rod 37 is stretched, and the drainage channel 35 and drainage hole 34 are staggered, with the actuating block 30 blocking the drainage hole 34. Once leakage is detected in the fixed rod 15, the electromagnet device 33 stops operating. With the spring rod 37 resetting, the drainage hole 34 and drainage channel 35 connect, and the leakage flows into the storage chamber 36. The micro diaphragm pump 31 then operates to extract the leakage from the storage chamber 36.
[0059] In this embodiment, a one-way valve is installed at the outlet end of the micro diaphragm pump 31.
[0060] In this embodiment, a humidity sensor is installed on the wall of the drain hole 34.
[0061] The working principle and beneficial effects of the above technical solution are as follows:
