The application discloses a motor control method and controller of an electric excavator and the electric excavator. The method comprises the following steps: acquiring the state of a pilot safety switch when the electric excavator is powered on; acquiring the state of a seat pressure switch when the state of the pilot safety switch is an off state; and sending a corresponding instruction to a motor controller to control the motor to stop or start according to the state of the seat pressure switch. The application can determine the action tendency of the operator by detecting the states of the pilot safety switch and the seat pressure switch, and can stop the motor in time when the operator leaves the cab or temporarily stops the hydraulic work, thereby effectively reducing the overall energy consumption and not affecting the normal operation of other electrical functions of the excavator.

The invention discloses a steel belt elevator with an anti-slip function and a control system, and relates to the technical field of steel belt elevators. According to the method, the number of impurity image blocks is accurately judged through gray value comparison and abnormal value screening, cleaning is started only when the number of the impurity image blocks is larger than the threshold value, assembly abrasion and energy consumption increase caused by the fact that impurities do not reach the risk value but are frequently cleaned are avoided, and a slipping accident caused by the fact that impurities exceed the standard but are not cleaned is also prevented; aiming at the scene that impurities are suddenly increased, the regulation and control module can immediately execute operations such as speed reduction and temporary stopping after receiving the sudden early warning, so that the friction loss of a steel belt and a traction wheel is reduced, slipping caused by sudden reduction of friction force in a short time is prevented, and the safety of passengers is guaranteed; for the scene of slow deterioration of impurities, accumulative early warning can remind operation and maintenance personnel to check root problems, and part damage caused by long-term neglect of small hidden dangers is avoided. And meanwhile, through advanced intervention, the elevator shutdown time caused by equipment faults is shortened, and the operation reliability of the elevator is improved.

This product is designed to run a vehicle on a rail track formed by connecting multiple rail toys together. The vehicle can travel or temporarily stop on the parallel rail track configuration, and while stopped, it rotates a display panel. A switch lever located between the tracks stops the vehicle when it is in the neutral position, and by swinging the switch lever inverted toward one of the tracks, the vehicle that was stopped on the inverted track can resume its movement. The vehicle is self-propelled, and the driving force of its wheels also operates the rail toys and the moving parts incorporated into this product. When the vehicle reaches a track within this product, its operation activates the display panel operating mechanism within this product, causing the display panel to rotate. When the vehicle resumes its movement by swinging the switch lever inverted, the rotation of the display panel stops. Furthermore, since the vehicle's movement or temporary stopping corresponds to passengers getting on and off at a station, it is primarily used in combination with station building toys.

The invention relates to a stop and release device (1) for temporarily stopping and releasing transport carriages (130, 131, 132) on a profiled rail (5) of a suspended conveying system (505), comprising a bar (20) which can be moved between a release position and a blocking position. According to the invention, - the stop and release device (1) has a main body (10) which is designed as a U-shaped bent sheet metal part having two U-limbs, - the bar (20) is designed as a U-shaped bent sheet metal part and is mounted on the main body (10) to pivot about an axis (60) extending through two U-limbs of the bar (20) and preloaded into the blocking position by means of a spring (100).

To provide a crane stop-time shaking stop control method capable of grasping a shaking state after a target position stop and stopping shaking with the minimum moving distance without veering from a target stop position.SOLUTION: After a target position of a crane has been reached, a shaking period T[s] and a shaking width D[mm] are measured from a rope length L[mm] and a shaking angle θ[°] in a state where the crane is temporarily stopped. On the basis of the shaking period T[s] and the shaking width D[mm] that have been measured, the number of inching times n[times], an inching frequency f[Hz], inching time t[s], an inching moving distance r[mm], and a suppression shaking width d[mm] that an inverter of an inching table prepared in advance gives to a motor are selected and set as parameters. An inching operation is performed with an inching operation based on the selected and set parameters and an inching operation having the same inching frequency f[Hz], the same inching time t[s] and an opposite inching direction as a set.SELECTED DRAWING: Figure 2
