[0030] By adopting the above technical solution, when in use, after the maintenance work is completed, the elevator maintenance personnel need to pull the two limit slides 63 synchronously, so as to drive the two limit slides 63 to move backwards, and then drive the two limit plugs 64 to move backwards and stretch the first spring 61. When the limit plugs 64 are completely separated from the corresponding limit countersunk holes 58, the two arc-shaped mounting plates 53 are pulled to move backwards, so that the limit plug rod 62 can be separated from the corresponding limit plug hole 59, and when the limit plug rod 62 is completely separated from the limit plug hole 59, the two worn cleaning groove brushes 54 are removed, and then the two new cleaning groove brushes 54 are reset and fixed according to the above steps.

A third guide rod 76 is fixedly installed on the upper end of the self-checking slide bar 73, and the third guide rod 76 and the second guide rod 75 are staggered, and the second guide rod 75 and the first guide rod 74 are not on the same horizontal line, so as to ensure that the first guide rod 74 and the second guide rod 75 are on the same horizontal line during the start of the detection operation and under normal circumstances when the wire rope has no height difference, and when the third guide rod 76 contacts the first guide rod 74 or the third guide rod 76 contacts the second guide rod 75, the buzzer alarm 71 will be powered on. This is the prior art and will not be described in detail here. A mounting ring 77 is fixedly sleeved on the upper end of the self-checking slide bar 73, and a second spring 78 is fixedly installed on the bottom end of the mounting ring 77, and the bottom end of the second spring 78 is fixedly connected to the lifting bracket 43.

[0032] By adopting the above technical solution, when the elevator is in use, the brake wheel 21 is locked by the brake 3 when the elevator is under maintenance, and then the electric telescopic rod 42 is started, so that the lifting bracket 43 can be driven to move downward, and then the cleaning groove brush 54, the first gear 55, the cleaning ring brush 56, the buzzer alarm 71, the fixed plug rod 72 and the self-checking slide bar 73 can be driven downward, and the first gear 55 can be further separated from the driving gear ring 52, and when the lifting bracket 43 moves down to the lowest point, the electric telescopic rod 42 is closed, at this time the self-checking slide bar 73 will contact the corresponding steel wire rope and put the second spring 78 in a stretched state. If the height difference between the steel wire ropes is within a normal range, the second spring 78 will drive the corresponding self-checking slide bar 73 to move autonomously, but the first guide rod 74 and the corresponding third guide rod 76 and the remaining third guide rods 76 and The corresponding second guide rod 75 will not contact, thereby not triggering the buzzer alarm 71. If the height difference between the steel wire ropes exceeds the normal range, the second spring 78 will drive the self-check slide bar 73 corresponding to the abnormal steel wire rope to continue to move downward, so that the second guide rod 75 or the third guide rod 76 on the corresponding self-check slide bar 73 can contact the adjacent first guide rod 74 or the corresponding third guide rod 76 or the second guide rod 75 on the adjacent self-check slide bar 73, and then the power can be turned on and the buzzer alarm 71 can be triggered, so that the self-check of the height difference of the steel wire rope can be realized and the elevator maintenance personnel can be reminded in time and accurately to inspect the steel wire rope and the traction wheel 22. There is no need for manual inspection by the elevator maintenance personnel, thereby saving manpower and improving the inspection efficiency and accuracy, and further effectively avoiding the phenomenon of safety hazards due to manual missed inspections and wrong inspections.

[0033] Working principle: When in use, the brake wheel 21 will drive the driving gear ring 52 to rotate synchronously, thereby driving the first gear 55 and the second gear 88 to rotate, and then driving the first rotating rod 51 and the second rotating rod 83 to rotate synchronously, and further driving the cleaning ring brush 56 and the two arc-shaped mounting plates 53 to rotate synchronously, thereby driving the two cleaning groove brushes 54 to rotate synchronously, and then the outer wall of the brake wheel 21 and the corresponding part of the brake shoe and the inner wall of the traction groove 23 can be effectively cleaned. At the same time, the second rotating rod 83 will drive the cleaning fan blade 84 to rotate, so that air can be sucked into the cleaning sleeve 81 through the air inlet perforation 85 and quickly introduced into the cleaning duct 87 through the air outlet through hole 86, and then the air will be quickly guided between the brake wheel 21 and the brake shoe, so as to avoid the phenomenon of insufficient braking force of the brake 3 and insufficient traction force of the traction wheel 22, thereby effectively ensuring the braking effect of the brake 3 and the traction effect of the traction wheel 22;

[0034] When the elevator is under maintenance, the brake wheel 21 is locked by the brake 3, and then the electric telescopic rod 42 is started, so that the lifting bracket 43 can be driven to move downward, and then the cleaning groove brush 54, the first gear 55, the cleaning ring brush 56, the buzzer alarm 71, the fixed plug rod 72 and the self-checking slide bar 73 can be driven downward, and the first gear 55 can be further separated from the driving gear ring 52, and when the lifting bracket 43 moves down to the lowest point, the electric telescopic rod 42 is closed, and the self-checking slide bar 73 will contact the corresponding steel wire rope and put the second spring 78 in a stretched state. If the height difference between the steel wire ropes is within the normal range, the second spring 78 will drive the corresponding self-checking slide bar 73 to move autonomously, but the first guide rod 74 and the corresponding third guide rod 76 and the remaining third guide rods 76 and the corresponding second guide rods 75 The second spring 78 will not contact, thus the buzzer alarm 71 will not be triggered. If the height difference between the steel wire ropes exceeds the normal range, the second spring 78 will drive the self-checking slide bar 73 corresponding to the abnormal steel wire rope to continue to move downward, so that the second guide rod 75 or the third guide rod 76 on the corresponding self-checking slide bar 73 can contact the adjacent first guide rod 74 or the corresponding third guide rod 76 or the second guide rod 75 on the adjacent self-checking slide bar 73, and then the power can be turned on and the buzzer alarm 71 can be triggered, so that the self-check of the height difference of the steel wire rope can be realized and the elevator maintenance personnel can be reminded in time and accurately to inspect the steel wire rope and the traction wheel 22, without the need for manual inspection by the elevator maintenance personnel, thereby saving manpower and improving the inspection efficiency and accuracy, and further effectively avoiding the phenomenon of safety hazards due to manual missed inspections and wrong inspections;

[0035] After the maintenance work is completed, the elevator maintenance personnel need to pull the two limit slides 63 synchronously, so as to drive the two limit slides 63 to move backwards, and then drive the two limit plugs 64 to move backwards and stretch the first spring 61. When the limit plugs 64 are completely separated from the corresponding limit countersunk holes 58, pull the two arc-shaped mounting plates 53 to move backwards, so as to separate the limit plug rod 62 from the corresponding limit plug hole 59, and when the limit plug rod 62 is completely separated from the limit plug hole 59, remove the two worn cleaning groove brushes 54, and then reset and fix the two new cleaning groove brushes 54 according to the above steps and start the electric telescopic rod 42 again, so as to drive the lifting bracket 43 to reset and make the first gear 55 mesh with the driving gear ring 52 again.
