Description

Double-car elevator with adjustable floor spacing

Technical Field

The utility model belongs to the field of elevators, and particularly relates to a double-car elevator with adjustable floor spacing.

Background

An elevator is a permanent transport device that serves a number of specific floors within a building with its car running on at least two rows of rigid guide rails that run perpendicular to the horizontal or at an angle of inclination of less than 15 ° to the plumb line. Traction elevators typically have at least one car and a counterweight for transporting passengers or cargo. A hoistway is a structure that ensures the building space required for safe operation of a car and counterweight, and the hoistway space is generally bounded by a pit floor, hoistway walls, and hoistway tops. The well is divided into a top layer, a middle layer and a pit from top to bottom.

In order to improve the utilization rate of a hoistway, improve the transportation capacity, and relieve the vertical traffic pressure, a double-car elevator is generated. The double-car elevators share a car frame. Later, in order to solve the problem that the floor spacing is not necessarily equal caused by the design and construction of the floor buildings, the elevator with adjustable floor spacing appears along with the elevator with double cabs. Currently, two-car elevators on the market basically realize the adjustment of the inter-car distance by connecting an upper car and a lower car through rigid structures such as a hydraulic cylinder or a scissor structure. Due to the rigid connection, passengers in the elevator car feel poor in comfort, and in addition, the dead weight of the upper elevator car and the weight of the passengers act on the lower elevator car together, so that the mechanical strength requirement on the lower elevator car is greatly increased. Because the dead weight of the upper lift car and the weight of passengers are born in a hydraulic cylinder form or a scissor structure form, the requirements on the hydraulic cylinder and the scissor structure are high, and the distance between the upper lift car and the lower lift car is smaller by adopting the hydraulic cylinder form and the scissor structure form.
