Steel belt traction household elevator with ultra-shallow bottom pit and short top layer

Abstract

The invention discloses an ultra-shallow pit and short top layer steel belt traction household elevator, and relates to the technical field of household elevators. The ultra-shallow bottom pit and short top layer steel belt traction household elevator comprises a hoistway and a bottom pit formed in the bottom of the hoistway. Lift car guide rail supports are fixedly arranged on the two sides of the hoistway correspondingly, lift car guide rails are arranged on the two lift car guide rail supports correspondingly, and the lift car guide rails are fixedly arranged on the two sides of the lift car frame correspondingly; a car top wheel is arranged at the top of the car frame, a car transition wheel beam and a car rope head fixing frame are arranged at the tops of the two rows of car guide rails, and a car rope head combination is arranged on the car transition wheel beam and the car rope head fixing frame. The elevator further comprises a lift car transition wheel and a wheel beam. The problems that in the prior art, a home elevator is dragged through a steel wire rope, and when the pit depth and the top layer height do not meet the standard requirement, due to the fact that a car bottom wheel or a car top wheel occupies a large space, and the selected steel wire rope is not suitable are solved.

Description

technical field [0001] The invention relates to the technical field of home elevators, in particular to an ultra-shallow pit and low top steel belt traction home elevator. Background technique [0002] The 3rd and 4th floor villas and townhouses in the city are generally equipped with home elevator shafts. Due to the limitation of civil structure, the bottom pit of home elevators is generally shallow. In our rural areas, with the change of local policies, the opening of rural house renovation and the increasing demand for elevators for home villas, the renovation of rural houses is subject to government policy regulations, and there are restrictions on building area and building height, so rural Villa home elevators are generally not high on the top floor. [0003] Conventional household elevators use wire rope traction to drive the elevator, that is, the elevator in which the wire hoisting rope is driven by the friction force of the driving wheel rope groove of the main en...

AI Technical Summary

Problems solved by technology

When the height of the top floor of the hoistway and the depth of the pit are not sufficient, it is more difficult to use the wire rope traction drive, and it may not be established.

[0004] The prior art home elevator adopts steel wire rope traction, and the minimum wire rope is φ6, so the minimum diameter of the guide wheel is 150mm. At this time, if the car bottom wheel is used, the depth of the pit is at least 350mm; Feel comfortable, the clear height of the car is at least 2100mm, and the clear height of the hall car door is 2000mm. 2900mm, so when the depth of the pit and the height of the top floor are not enough to meet the standard requirements, it is not appropriate to choose the steel wire rope because the car bottom wheel or car top wheel takes up a lot of space

For the above-mentioned problems, no effective solutions have been proposed so far
