The overall design concept of the wheelchair lift for the villa:
(1) In terms of civil construction, in order to meet the needs of family use, the top station and bottom pit of the elevator need to match the civil construction size of the civil residence as much as possible, and the top station of the household elevator needs to be less than or equal to 3300mm, or even below 3000mm;
The pit size should be within 350mm, or even zero. The width and depth of the elevator shaft are related to occupying the effective area of the house, and it is a relatively realistic problem to reduce the size of the shaft as much as possible. At the same time, inside the car, it is advisable to configure buttons with Braille, control panels for the disabled, and handrails to facilitate the use of the disabled.
(2) From the configuration point of view, in order to meet the strong demand for quiet products and low noise in the family, the wheelchair lift needs to be equipped with a permanent magnet series traction machine. This is mainly because the permanent magnet traction machine is not like the turbine worm traction machine. No lubricating oil is required for operation, and the overall energy consumption is reduced by about 30% compared with other traction machines due to the reduction of the energy consumption of the excitation current. It can be said to be a green and environmentally friendly drive system with low noise; 90~100 rpm, the torsional vibration is small, the noise is low; the power consumption is small, and the average power consumption is sometimes lower than that of a refrigerator in one day of operation; and long-life self-lubricating bearings can be used. The purpose of "maintenance-free"; in addition, the floor spacing of residential buildings is generally about 2700-3300mm, and there is no condition for building a machine room on the roof. form. For household wheelchair lifts, under the operating conditions of the elevator at the user's home, it is impossible for maintenance personnel to enter the user's home to refuel the guide rails. . At the same time, the model of the guide rail should be as small and light as possible under the condition that the operation meets the conditions. The purpose is to be suitable for family use and easy to install.
