Definitions
- the present invention relates to an elevator control device including a plurality of sheaves and motors that respectively drive these sheaves.
- this type of conventional elevator includes a main rope that couples a counterweight for each force, a plurality of sheaves around which the main rope is wound, A plurality of motors that respectively drive the sheaves and a plurality of speed control devices that control the torques of these motors are provided, and a required operation mode is executed according to the speed command values to these speed control devices.
- Patent Document 1 Japanese Patent Laid-Open No. 55-106971
- the present invention has been made to solve the above-described problems.
- an elevator equipped with a plurality of sheaves and motors that respectively drive these sheaves the sheaves of the sheaves are missing.
- the purpose of this is to increase the safety of the elevator.
- the present invention relates to a main rope that couples a cage and a counterweight, a plurality of sheaves around which the main rope is wound, a plurality of motors that respectively drive these sheaves, and these motors It is equipped with a plurality of speed control devices that control the torque of each of them. Compare the torque command value of each speed control device to the elevator control device that executes the required operation mode according to the command value, and if the difference exceeds the predetermined reference value, V, When one of the sheaves has a traction failure, it is equipped with an abnormality detection device that outputs an abnormality signal. If the abnormality detection device outputs an abnormality signal, each speed control device is selected according to the operation mode at that time. The speed command value with respect to is changed.
- the present invention in an elevator equipped with a plurality of sheaves and motors that respectively drive these sheaves, it is possible to detect idling due to traction of a sheave and according to the traveling state of the elevator. Therefore, if the vehicle is run with reduced acceleration, constant speed, or deceleration, it can return to the normal state where the truncation is lost, or if the abnormal force cannot be recovered, stop suddenly before a secondary failure occurs. Therefore, a safer elevator control device can be provided.
- Embodiment 1 of the present invention will be described below with reference to FIG.
- a car 1 and a counterweight 2 are connected by a main rope 3 and wound around two sheaves 4a and 4b driven by different lifting motors 5a and 5b.
- the elevator car speed command value is given from the speed command generator 7 to the speed controllers 6a and 6b of the lifting motors 5a and 5b, and each speed controller 6a and 6b receives its speed command.
- the torque command value is given to each lifting motor 5a, 5b so as to follow the value to control their output torque, and the main rope 3 is driven to drive the elevator car 1 by driving each sheave 4a, 4b.
- the abnormality detection device 8 compares the torque command values a and b, which are output signals of the speed control devices 6a and 6b, and generates a speed command as a truncation omission error when the difference exceeds a predetermined reference value. An abnormal signal is output to the device 7, and the speed command values a and b for the speed control devices 6a and 6b are changed according to the operation mode of the elevator at that time.
- Fig. 2 shows a specific configuration of the abnormality detection device 8, and Fig. 3 shows signal states at various parts when an abnormality is detected.
- the calculator 81 calculates
- ⁇ a ⁇ b.
- an abnormality determination flag is output (Fig. 3 (b)).
- the latch circuit 83 latches it as an abnormality signal (FIG. 3C). As a result, it is possible to detect the truncation of the sheave 4b.
- the power of the sheaves 4a and 4b being the same diameter. If the diameter of the sheaves 4a and 4b is different from Da and Db, the comparator 82
- FIG. 4 is a flowchart for explaining the operation of the first embodiment of the present invention.
- step 100 it is determined whether or not the vehicle is traveling. If the vehicle is traveling, it is determined in step 200 whether or not an abnormality in truncation is detected. If a truncation omission abnormality is detected, the operation mode is judged next.
- step 300 it is determined whether or not the vehicle is accelerating. If the vehicle is accelerating, the vehicle is driven with a reduced acceleration in step 301. If it is not accelerating, then, at step 310, it is determined whether or not the force is constant. If it is at a constant speed, reduce the speed at 311. If it is not at a constant speed, it means that the vehicle is decelerating. Therefore, determine whether the deceleration distance is sufficient at step 320.
- step 700 stop the elevator suddenly.
- steps 301, 311, and 321 the acceleration, constant speed, and deceleration are decreased, respectively, and in step 400, it is determined whether or not a fixed time t has elapsed after the abnormality is detected.
- FIG. 1 is an explanatory block diagram illustrating an elevator control apparatus according to Embodiment 1 of the present invention.
- FIG. 2 is a block diagram showing an abnormality detection apparatus in the first embodiment.
- FIG. 3 is a diagram showing signal states for explaining the operation of the abnormality detection device in the first embodiment.
- FIG. 4 is a flowchart for explaining the operation of the first embodiment.
