Detailed Description
Referring to fig. 1-3, the air cooler airtightness detection device is provided with an unpowered roller conveyor line A1 and an unpowered roller conveyor line B2 which are oppositely arranged in front and back, a water tank 3 is arranged between the two unpowered roller conveyor lines, and transparent glass 4 is arranged on four tank walls of the water tank 3; a fixed rack 5 is arranged on the upper side of the water tank 3, an air cylinder 6 which is vertically arranged downwards is arranged at the top of the fixed rack 5, and the telescopic end of the air cylinder 6 is connected with the top of a hoisting frame 7; the hoisting frame 7 comprises a rectangular frame 701 and an unpowered conveying roller 702 which are corresponding to each other up and down, and four corners of the rectangular frame 701 and the unpowered conveying roller 702 are correspondingly connected through vertical connecting rods 703; the fixed rack 5 is provided with support columns 8 which are correspondingly arranged with each vertical connecting rod 703, the lower ends of the support columns 8 are provided with guide wheels A9 matched with the vertical connecting rods 703, and the upper ends of the vertical connecting rods 703 are provided with guide wheels B10 matched with the support columns 8.
In this embodiment, the cross sections of the vertical connecting rod 703 and the supporting upright post 8 are both rectangular structures; the guide wheel A9 and the guide wheel B10 both adopt V-shaped nylon track pulleys.
In this embodiment, the front side of the fixed rack 5 is further provided with a vertical pillar 11, the upper end and the lower end of the vertical pillar 11 are respectively provided with a travel switch 12, and each travel switch 12 and the cylinder 6 form an electric linkage; an L-shaped touch bracket 13 is horizontally arranged on the front side of the rectangular frame 701, and a front cross bar of the touch bracket 13 corresponds to a roller at the swing arm end of the travel switch 12.
When the air cooler lifting device works, firstly, the air cylinder 6 is started, the piston rod of the air cylinder 6 retracts to pull the lifting frame 7 to ascend, when the unpowered conveying roller C702 on the lower side of the lifting frame 7 is level with the working surface of the unpowered conveying roller A1, the L-shaped touch bracket 13 on the lifting frame 7 just touches the roller on the travel switch 12 at the upper end of the vertical strut 11, so that the travel switch acts, the air cylinder 6 is controlled to stop running, and at the moment, the air cooler collected on the unpowered conveying roller A1 is manually pushed onto the unpowered conveying roller C702;
then, gas with certain pressure is filled into the air cooler through the inlet/outlet interface of the air cooler, the inlet/outlet interface of the air cooler is sealed, and a certain amount of water is held in the water tank 3 in advance to prepare for the next air tightness detection test;
then, the cylinder 6 is started again, the piston rod of the cylinder 6 is controlled to extend out, and the downward stroke of the cylinder is controlled by a stroke switch 12 arranged at the lower end of the vertical strut 11; when the hoisting frame 7 bears the air cooler and descends to the right position, and the water surface in the water tank 3 is calm, whether bubbles appear in the water tank 3 is observed, and therefore the air tightness of the air cooler is judged.
