an elevator shaft

Abstract

The invention relates to an elevator shaft, which includes polygonal columns, a bottom plate, a top plate, a car frame and a counterweight frame. The car frame includes an upper beam, a car column and a bottom beam. Boots, the counterweight frame includes counterweight beams and counterweight columns, at least four hollow polygonal columns are arranged in the well, and column piles are also provided in the well, and the column piles are screwed to the polygonal columns On both ends, the bottom plate and the top plate are respectively placed at the two ends of the multi-edge column and are threadedly connected with the column piles. The multi-edge column is used to cooperate with the guide shoes on the car through the rectangular protrusions on the multi-edge column. In addition, the four-track structure is adopted, and the polygonal columns cooperate with the guide shoes at the top corners of the car, which eliminates the phenomenon of aggravated wear of the guide shoes when the car is unbalanced, thereby increasing the operating efficiency of the elevator. Stability, reduce installation cost, improve installation accuracy, and save the space occupied by the elevator at the same time.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator shaft. Background technique [0002] With the improvement of people's living standards, the demand for elevators in people's daily life continues to increase. In view of the lack of supporting facilities in the early apartment buildings, elevators cannot be directly installed inside the apartment. When in use, the elevator needs to be installed outdoors through civil engineering or existing steel parts to build the shaft. At the same time, car guide rails and counterweights need to be installed in the shaft. guide rails, so a large hoistway area is required; and the installation process of the existing elevator shaft is cumbersome, a large number of processes need to be completed on site, the construction period is long, the installation cost is high, and the overall accuracy of welding is not high, which affects Effect of use; In addition, the existing car frames ...

Problems solved by technology

In view of the lack of supporting facilities in the early apartment buildings, elevators cannot be directly installed inside the apartment. When in use, the elevator needs to be installed outdoors through civil engineering or existing steel parts to build the shaft. At the same time, car guide rails and counterweights need to be installed in the shaft. guide rails, so a large hoistway area is required; and the installation process of the existing elevator shaft is cumbersome, a large number of processes need to be completed on site, the construction period is long, the installation cost is high, and the overall accuracy of welding is not high, which affects Effect of use; In addition, the existing car frames are equipped with uprights on both sides near the middle, and the guide shoes on the uprights are used in conjunction with the car guide rails. When the car is unbalanced, the force on one side of the guide shoes will be increased. The wear of the guide shoes increases and generates noise, which affects the smoothness of the elevator operation and increases energy consumption
