Description
Technical Field
The utility model relates to an alarm device, especially a conical motor braking ring wearing and tearing alarm device.
Background
The conical rotor motor is a motor with a conical stator inner cavity and a conical rotor shape, has the capability of power failure self-braking, is widely applied to hoisting equipment such as an electric hoist, a winch and the like, and a braking device of the conical rotor motor consists of a braking spring sleeved on a motor rotor, a fan braking wheel and a braking ring on an end cover. When the motor runs, the air gap magnetic field of the conical rotor motor generates axial magnetic pulling force to compress the brake spring, so that the fan brake wheel is separated from the brake ring on the motor end cover, and the motor can rotate freely. When the power is cut off, the axial magnetic pull force disappears, the rotor generates axial movement under the thrust of the brake spring, so that the fan brake wheel tightly presses the brake ring to generate friction force to force the motor to stop rapidly and bind the rotor, thereby preventing the lifted heavy object from falling and ensuring the safety;
however, in the process of braking experiments on 7.5kw and 13kw motors, it is found that after frequent braking, the braking ring is inevitably worn, so that the braking effect is affected, but after the wear, the wearing cannot be found timely, so that the potential safety hazard in the production process is often caused by the fact that the braking cannot be rapidly realized.
Therefore, a brake ring abrasion alarm device of a conical motor, which has a simple structure and is convenient to install and can find the abrasion of the brake ring in time, is urgently needed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a conical motor brake ring wearing and tearing alarm device, simple structure, simple to operate, and can in time discover brake ring wearing and tearing.
The utility model provides a following technical scheme:
the utility model provides a conical motor brake ring wearing and tearing alarm device, including fan brake wheel and with the brake ring on the motor end cover that fan brake wheel formed the braking still includes insulating cover, screw rod and siren, insulating cover is fixed on the motor end cover of brake ring one side, screw rod threaded connection be in the insulating cover centre bore, screw rod one end is passed insulating cover and with one side of fan brake wheel forms the clearance, and links to each other through the one end of wire with the siren, the other end of siren pass through the wire with the motor end cover is connected, and be close to the screw rod tip of fan brake wheel with form between the fan brake wheel the circular circuit that switches on of siren opens circuit.
Preferably, the screw rod is further in threaded connection with a locking nut fixed on the insulating sleeve.
Preferably, the insulating sleeve is a nylon insulating sleeve.
The utility model has the advantages that: when the brake ring is worn to a certain degree, the fan brake wheel can contact the end part of the screw rod in the device, and the screw rod, the fan brake wheel, the machine shaft, the bearing and the motor end cover are all made of conductive materials, so that the alarm, the screw rod, the fan brake wheel, the machine shaft, the bearing and the motor end cover can form a direct current electrified loop, and the alarm is triggered to sound quickly.
