specific Embodiment approach 1
[0023] Specific implementation mode one: refer to Figure 1 to Figure 2 Specifically explain this embodiment, the van elevator based on screw rotation drive described in this embodiment, it includes: a motor 1, a plurality of nuts 2, a transmission rod 3, a control panel 5 and a car 6;
[0024] The inside of the car 6 is provided with a partition, which divides the interior of the car 6 into an equipment chamber and a passenger chamber, the motor 1, a plurality of nuts 2 and the transmission rod 3 are located inside the equipment chamber, and the control panel 5 is located in the passenger chamber Inside, the side facing the equipment cavity and the elevator shaft wall 4 is an open structure;
[0025] A plurality of nuts 2 are arranged coaxially from top to bottom, and the motor 1 simultaneously drives the plurality of nuts 2 to rotate synchronously through the transmission rod 3;
[0026] The surface of the elevator shaft wall 4 is provided with oblique threads, and the exte...
specific Embodiment approach 2
[0032] Specific embodiment 2: This embodiment is a further description of the van elevator based on screw rotation drive described in specific embodiment 1. In this embodiment, the control panel 5 includes the following units:
[0033] Data storage unit: store the height value of each floor and the distance value raised by the nut 2 for one rotation, and send the height value and the distance value to the motor rotation signal acquisition unit;
[0034] Signal acquisition unit: collect the signal of the number of floors on the current floor of the elevator and the number of floors of the elevator target floor, and send them to the motor rotation signal acquisition unit. The number of floors of the stairs is a continuous integer;
[0035] Motor rotation signal acquisition unit: make a difference between the elevator’s current floor number signal and the elevator’s target floor number signal to obtain the floor difference. If the difference is greater than zero, an elevator down ...
specific Embodiment approach 3
[0039] Specific embodiment 3: This embodiment is a further description of the van elevator based on screw rotation drive described in specific embodiment 2. In this embodiment, the number of rotations k of the motor is as follows:
[0040] k = | N - M | × X Y ,
[0041] Among them, N is the number of floors where the elevator is currently located, M is the number of floors of the elevator target floor, X is the height value between each floor, and Y is the distance value that the nut 2 rises after one rotation.
[0042] The formula for the number of revolutions of the motor proposed in this embodiment is simple, and it is easier to realize by programming in the controller, which reduces the manufacturing difficulty.
