    摘要： Disclosed are an online monitoring system for a crack on a hoist spindle and an operation method thereof. The system comprises: a rope power part, a crack detection part, a wireless transmission part, and a computer. The rope power part comprises two traction ropes, two guide wheels, two stepper motors, and two stepper motor drivers. The crack detection part comprises a spiral tube guide rail, a sliding body, and an ultrasonic generator. The wireless transmission part comprises three zigbee wireless sensing modules. The zigbee wireless sensing modules receive instructions from the computer and transmit the instructions to the stepper motor drivers to control the motors to rotate. The stepper motors drive the guide wheels to rotate to realize the winding of the ropes, so as to pull the sliding body to slide on the spiral tube guide rail. The ultrasonic generator clamped on the sliding body monitors the rotating spindle along the spiral tube guide rail. The zigbee wireless sensing modules transmit the detected data to the computer in real time. The present invention can effectively monitor a hoist spindle in time before a failure occurs, thereby avoiding safety accidents.

    摘要： A shock-absorbing and energy-collecting roller cage shoe including a base, a main energy-collecting module, two auxiliary energy-collecting modules, and a roller is provided. The base is provided with three containing spaces for containing the main energy-collecting module and the two auxiliary energy-collecting modules. In the three containing spaces, the main energy-collecting module and the two auxiliary energy-collecting modules are respectively connected fixedly to the base through wire rope shock absorbers, the main energy-collecting module and the two auxiliary energy-collecting modules are respectively pressed on the left side, the upper side and the lower side of the roller, and the right side of the roller is pressed on a cage guide. The energy-collecting modules collect vibrational energy generated by vibration in the operation process of a lifting container, and convert the vibrational energy into collectable piezoelectric energy. The piezoelectric energy can be used to supply electric energy to electricity-consuming installations, such as such as the illumination of the lifting container, and thereby the collection and utilization of energy are realized.

    摘要： A hoist main shaft torque monitoring device based on angle measurement, constituted primarily by a first base, a second base, a light generating unit, a shutter, and a light sensing element; the light source, a first lens, and a first optical aperture arranged in the light generating unit, as well as a second optical aperture, second lens, and light sensing element on the shutter, forming a light source generation, propagation, and reception pathway; when the elevator main shaft is subjected to a certain torque, a corresponding displacement is produced between the first optical aperture and the second optical aperture, thus measuring the change in amount of light ultimately reaching the second optical aperture so as to measure the twist angle of the rotary shaft and finally calculate the magnitude of the shaft torque. Without damaging the original equipment and foundation, the device measures the torque of the shaft at different rotational speeds. The device can measure stationary torque and torque at different rotational speeds of the shaft, without the electromagnetic field interfering with wireless transmission; the device is easy to use, maintenance costs are low, and it is of interest for widespread popularization.
