Embodiment Construction
[0037] The above description is only an overview of the technical solution of the present invention. In order to understand the technical means of the present invention more clearly and implement it according to the description, the preferred embodiments of the present invention will be described in detail below with accompanying drawings.
[0038] like figure 2 As shown, a kind of corridor based on double screw nut mechanism can be used by two people, including: double screw guide rail guide rails 7 and 8 extending along the corridor, power unit stepper motor 9, and carrying platform. When the device is used, the control The controller selects a high-performance, high-stability PLC controller.
[0039] The stepper motor is arranged near the lower end of the guide rail groove, and the speed change mechanism includes the motor's own reducer, the belt transmission reduction ratio and the motor speed governor controlled by PLC. The output shaft of the stepping motor is connecte...

The invention discloses a corridor double-person riding elevator based on a double-screw-rod nut mechanism, and belongs to the technical field of corridor elevator mechanical devices. The invention ismainly used for providing a corridor elevator device which is simple in structure, low in manufacturing cost, convenient to use and stable and safe in operation for a building which is old in facilities and cannot bear a huge expense of modifying a box-type elevator; the double-person riding elevator mainly comprises double screw rod guide rails which are arranged in guide rail grooves along a corridor extension device, nuts for fixing a supporting body are installed on the screw rod guide rails , and a driving device provides torque for the double-screw rod through a two-stage synchronous belt; and the supporting body is connected with a conveying and carrying platform, the conveying and carrying platform comprises two pedals and a handrail, gravity sensors are arranged on the pedals andsense whether a passenger is trampling or not, the conveying and carrying platform can move up and down in the direction of the screw rod guide rails, a PLC controls the sequential action of the whole device, so that the function of stably and safely conveying the passenger to go up stairs and down stairs are completed.
Description
technical field [0001] The invention belongs to the technical field of corridor elevator mechanical devices, and relates to an elevator based on a double-nut mechanism in which two people can ride in a corridor. Background technique [0002] According to the research data of the China Population and Development Research Center in 2015, the average construction time of the houses used by the elderly in China was after the 1980s, and most of the buildings at that time were below six or seven floors. 28.9% of the elderly in the country live in buildings below the seventh floor that do not have auxiliary facilities for going up and down stairs. Elderly users living in these buildings on the third to seventh floors have difficulties in going up and down. Based on the 221 million elderly population, tens of thousands of elderly people in China are "hanging in the air" like tree people. Therefore, going up and down stairs has not only brought huge inconvenience to the elderly, the...
