A trailer-mounted corridor elevator ladder frame

Abstract

The invention relates to a trailer-type corridor elevator ladder frame, which belongs to the technical field of general equipment-elevators. The invention includes upper and lower guide wheel assemblies, a frame and a trailer frame. The upper guide wheel assembly is composed of a swing mechanism and a guide wheel. The swing frame is fixedly connected with the swing shaft. The swing shaft is installed in the bearing. The bearing seat is fixed on the vertical plate on the frame. Vertical guide wheels. The lower guide wheel assembly is also composed of a swing mechanism and a guide wheel, the frame includes a vertical plate and a six-sided cubic frame, and the power assembly includes a reduction motor and gears. The reduction motor is installed on the vertical plate, and its output shaft is equipped with a gear, which meshes with the rack below the lower guide rail. The trailer and the rack are connected flexibly, and load-bearing wheels are provided at the bottom. The main feature of the present invention is that the guide and load-bearing can be separated, and can also be stacked, which basically has no influence on the normal passage of the corridor. The elevator has a heavy load and a strong carrying capacity. In addition, the rack is located under the guide rail, so the rack is not easy to drop debris, and it can also reduce the phenomenon of unbalanced load crawling.

Description

technical field [0001] The invention belongs to the technical field of general equipment-elevators Background technique [0002] In recent years, in order to help the elderly go up and down the stairs, a new type of stair-climbing tool-corridor elevator came into being. Existing corridor elevator can be divided into linear type and curved type two classes according to running trajectory. The advantage of the straight type is that it takes up less space in the corridor, but the disadvantage is that because the track cannot be turned, an elevator can usually only climb half a floor. Like this, just need many relays if use linear elevator for the building more than two floors. The advantage of the curved shape is that the elevator can run uninterruptedly between floors, so the buildings used are theoretically not limited by floors. But this kind of elevator also has an obvious disadvantage, that is, the curved guide rail takes up a lot of space, which affects the normal pass...

Problems solved by technology

However, this kind of elevator also has an obvious disadvantage, that is, the curved guide rail takes up a lot of space, which affects the normal passage of the corridor.

Due to the above reasons, existing corridor elevators are mostly used in buildings or private residences below three floors, and are difficult to popularize in multi-storey residences that urgently need to solve the difficulty of climbing stairs.
