Principle of operation
When the elevator buffer detection system based on the internet of things starts to be started from a static state, the signal emitter 28 emits and receives a terminal signal of the internet of things, the fixed hydraulic cylinders 22 on the two sides move towards the buffer cylinder body 26 to drive the fixed rubber block 24 to fix the buffer cylinder body 26, the pressure detection hydraulic piston 38 moves downwards to drive the force measurement jacking block 30 to contact with the buffer, the pressure detection sliding block 33 moves under pressure, and if the first stroke contact 31 and the second stroke contact 36 are not in contact yet and the first pressure contact 32 is in contact with the second pressure contact 35, the terminal of the internet of things judges that the buffer is rusted, so that the normal buffering working effect is influenced.
At the moment, the internet of things terminal sends an instruction, the ash removal air pump 66 is started to blow in external air through the spray nozzle 16, meanwhile, the lifting motor 12 is started to drive the lifting nut 13 to rotate, and the lifting screw 11 moves up and down in a reciprocating mode to drive the lifting block 15 to perform ash removal operation on the buffer. After the ash removal is finished, the rust remover pump 64 is started, the rust remover is sprayed out from the spray head 16, and meanwhile, the lifting screw 11 moves up and down in a reciprocating manner to drive the lifting block 15 to remove rust for the buffer. When the spraying of the rust remover is finished, the wiping electromagnetic block 17 is started, the wiping rod 19 moves to a position close to the surface of the buffer cylinder 26, the wiping motor 18 is started to drive the wiping rod 19 to rotate, and the wiping rod 19 drives the wiping cloth strip 20 to wipe the surface of the buffer for cleaning.
If the first stroke contact 31 is in contact with the second stroke contact 36, but the first pressure contact 32 is not in contact with the second pressure contact 35, the terminal of the internet of things judges that the buffer is lack of oil and the buffering effect is insufficient. The internet of things terminal sends an instruction, the oiling body electromagnetic block 39 starts to drive the oiling body 40 to move to the upper side of the oiling port cover 50, the screwing cover lifting electromagnetic block 46 starts to drive the screwing cover lifting block 47 to move downwards, the screwing cover 49 is in nested contact with the oiling port cover 50, the screwing cover motor 48 starts to screw the oiling port cover 50 from the oiling port 51, the screwing cover lifting electromagnetic block 46 drives the screwing cover lifting block 47 to move upwards, and the screwing cover electromagnetic block 43 drives the screwing cover body 45 to move towards the direction far away from the buffer cylinder body 26 to give way of space for the oiling rod. The oil filling rod electromagnetic block 42 is started to drive the oil filling rod 62 to extend into the oil filling port 51, and the oil filling port sealing ring 44 seals a gap between the oil filling port 51 and the oil filling rod 62. Meanwhile, the oil filling rod electromagnetic block 42 pushes the oil filling rod 52 to move, the oil filling valve head 56 moves towards the direction of the oil filling rod 62, the oil tank 41 is communicated with the oil filling hose 61, and oil enters the oil filling opening 51 to perform oil filling operation.
