Description

An elevator structure with integrated car and car frame

technical field

The invention relates to the technical field of elevator structures, in particular to an elevator structure in which a car and a car frame are integrated.

Background technique

Common elevators on the market are generally composed of two parts: a car and a car frame. The car refers to the internal box structure where passengers ride. The main structure of the car is composed of three parts: the car wall, the upper car floor and the car roof; The beam, the lower car bottom and the column are composed of three parts. Since the shock-absorbing structure between the car and the car frame is an elastic structure, a sufficient distance needs to be reserved between the car and the car frame to avoid hitting the car when the car shakes. The car frame produces vibration and noise. This makes the car and the car frame form an inner and outer two-layer structure, resulting in a larger area of the hoistway in the direction of the guide rail gauge, and the double-layer car bottom structure will also require a greater depth of the pit. The requirements are getting higher and higher, but the inner and outer two-layer structure of the original car and car frame limits the size of the hoistway occupied by the elevator, so that the utilization rate of the hoistway occupied by the elevator has not been maximized. In addition, the two-part structure of the car and the car frame has more parts, and the manufacturing and installation time is longer.
