Description

Villa elevator car frame

Technical Field

The utility model relates to a villa elevator sedan-chair frame belongs to elevator technical field.

Background

The villa elevator is a special elevator and has the characteristics of small car area, light load, generally no more than 400kg of load, low running speed, generally less than 0.4m/s of running speed and the like. In order to ensure the running safety of the elevator, when the descending speed of the elevator car exceeds a set value, the elevator must be stopped in time, after the speed limiter is installed, the descending speed of the car is detected in a mechanical mode, when the elevator descends and exceeds the speed limit, a braking device of the car controls the emergency braking of the elevator, the speed limiter controls a steel wire rope of the speed limiter to be fixed, and if the elevator continues to move, the safety tongs are driven to brake. For example, chinese patent publication No. CN108328460A discloses an integrated villa elevator car frame, which includes vertical side beams disposed at both sides of an elevator and a lower car bottom below the elevator, the vertical side beams are fixedly connected to the lower car bottom, grooves are formed along both side walls of the lower car bottom, return rope wheels are disposed in the grooves of the lower car bottom at both sides of the vertical side beams, the axes of the return rope wheels are parallel to the length direction of the grooves, first support frames parallel to the width direction of the elevator are fixedly connected to the upper ends of the vertical side beams, a through shaft is disposed between the first support frames of the two vertical side beams, the through shaft penetrates through the first support frames and is rotatably connected with the two first support frames, and safety tongs are disposed at the upper ends of the outer surfaces of the vertical side beams. The belt return rope wheel system is arranged in the lower car bottom, so that the height space is saved, the safety gear linkage mechanism and the lifting mechanism are arranged at the upper end of the vertical side beam, the replacement of a steel wire rope by workers is facilitated, and the problem that the height of a top layer is too low is solved. However, in this car frame, the diversion sheave is mounted on the bottom of the car bottom, which increases the height of the car frame, and accordingly, the depth of the elevator pit must be increased, which increases the construction cost of the elevator pit.
