AI Technical Summary
The centralized control system of traditional ring coolers cannot detect when the ring cooler trolley wheels stop or become intermittently jammed, or when the drive friction wheel and rotating frame slip, resulting in serious material accumulation in the equipment, affecting production and increasing maintenance costs.
The slippage detection device, which uses a fixed bracket and a non-contact detection switch, identifies slippage by detecting the interval between the bolts at both ends of the synchronously rotating wheel, combined with real-time monitoring by the controller, and alerts staff to check.
It enables timely identification of slippage on the ring cooling trolley, reduces material accumulation on the equipment, lowers maintenance costs, reduces the labor intensity of workers, and avoids equipment damage.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of ring cooling machine fault detection, especially relates to a skid detection device of ring cooling trolley in ring cooling machine. BACKGROUND
[0002] The sintering ring cooling machine is mainly composed of a ring cooling trolley, a rotary frame, upper and lower seals and a ring track. The rotary frame is driven by a driving device, a main friction wheel and a passive friction wheel to rotate the ring cooling trolley through a clamping frame and a friction disc. When a trolley wheel falls off, the faulty wheel causes the trolley to stop or to be intermittently blocked, but the centralized control system still shows that the sintering ring cooling machine variable frequency drive system is operating normally. The sintering machine and the power system cannot receive the trolley fault signal and remain normal operation, which causes serious equipment accumulation. In addition, the friction wheel and the rotary frame are prone to skidding in rainy and snowy weather, which reduces the transmission efficiency and damages the equipment. Long-term accumulation of materials will cause serious blockage of the feed inlet, discharge outlet and connecting pipeline, resulting in equipment failure or damage, increased labor intensity of workers in cleaning the accumulated materials, increased maintenance cost of the ring cooling machine and affected normal production.
