Abstract: An operation locking device for a climb-free system includes a locking assembly, a fixing block and a triggering assembly. The fixing block is mounted on a climb-free system trolley. The locking assembly is connected to the fixing block by the triggering assembly. The triggering assembly is configured to control the locking assembly to be switchable between a locked state and an unlocked state. When the climb-free system trolley is out-of-control, the triggering assembly triggers the locking assembly to switch to the locked state and to be clamped in a sliding rail, such that the climb-free system trolley stops operating. When the climb-free system trolley needs to adjust a working position by sliding up and down, the triggering assembly triggers the locking assembly to switch to the unlocked state and to be disengaged from the sliding rail.

Abstract: The present application relates to the technical field of lifting equipment, and provides a traction machine and a lifting equipment. The traction machine includes traction pulleys, traction ropes driven by the traction pulleys and fixed pulleys for changing directions of the traction ropes. The fixed pulley is provided with a sensor sensing member rotating with the fixed pulley, a traction machine sensor is arranged beside the fixed pulley; the traction machine sensor is configured to detect a rotation speed of the sensor sensing member, and send the rotation speed to a controller of the traction machine; the controller controls a rotation of the traction pulley according to detected data of the traction machine sensor. Since this kind of traction machine is provided with the sensor sensing member and the traction machine sensor, it is capable of detecting whether the traction machine has an abnormal operation, and stopping the traction machine immediately in an abnormal state.

Abstract: A method and a device for controlling a compressor to stop are disclosed in the present disclosure. The method includes: acquiring a rotor phase corresponding to a minimum load of the compressor; during a shutdown process of the air conditioner, acquiring a current orientation of the rotor of the compressor and determining whether a phase of the rotor is the rotor phase corresponding to the minimum load according to the current orientation of the rotor; and controlling the compressor to stop if determining that the phase of the rotor is the rotor phase corresponding to the minimum load. Therefore, a generated vibration and stress of a piping is smaller than that generated by directly stopping the compressor, to effectively reduce the vibration and stress of the piping at the moment that the compressor is stopped and to avoid a danger of breaking the piping.

Abstract: An air conditioner, a method and a device for controlling a compressor in the same are disclosed in the present disclosure. The method includes: during a shutdown process of the air conditioner, controlling a drive circuit of the compressor to short three phase windings of the compressor if receiving a stop signal for stopping the compressor; and controlling a rotor of the compressor to stop according to a brake torque generated by shorting the three phase windings, to stop the compressor. The method shorts the three phase windings by controlling the drive circuit, thus to generate the brake torque to control the rotor to stop faster. As a result, the method enables the compressor to stop and to stay still rapidly, thereby facilitating to reduce a piping stress in the air conditioner and to prolong a working life of a pipe in the air conditioner.

Abstract: An air absorbing and discharging massager, comprising: a housing, an air pump, a solenoid valve, a PCB board and a silicone massaging case connected to the air pump through a nozzle rack; the air pump connected to the solenoid valve. The air pump and the solenoid valve controls the silicone massaging case to absorb or release air so as to obtain a squeezing and inflating massage effect; the nozzle rack includes a filter screen. A user is covered by the massage cavity and uses an air pump and a solenoid valve to realize an air absorbing and releasing action, so that the massage cavity can be squeezed or inflated, and the user can receive a comfortable massaging and stimulating feeling.
