A safety elevator car

Abstract

The invention discloses a safety elevator car. An elevator control cabinet is arranged inside the elevator car. An elevator lower beam is arranged at the bottom of the elevator car. A counterweight mechanism is connected to the elevator car; the counterweight mechanism includes a counterweight block. The counterweight is connected to the elevator car through steel cables, the counterweight is connected to the counterweight guide rail through the counterweight guide shoe, and the counterweight guide rail is fixed to the elevator shaft through the counterweight bracket. The elevator control cabinet includes a bottom box and a cabinet door. The bottom box includes a bottom plate, one side of the bottom plate is bent forward to form a first plate, and the other side of the bottom plate is first bent forward and then inward to form a second plate; the cabinet door includes a panel, one of which is The side is bent backwards to form a third plate, and the other side of the panel is bent backwards to form a fourth plate, a notch is arranged along the fourth plate, and a hinge is arranged in the notch. The present invention simultaneously improves the structures of the elevator control cabinet, the elevator lower beam and the counterweight bracket, so that the elevator car has the advantages of easy maintenance, high safety, high manufacturing efficiency and low cost.

Description

technical field [0001] The invention belongs to the field of elevator cars, in particular to a safe elevator car. Background technique [0002] An elevator control cabinet is arranged in the elevator car, an elevator lower beam is arranged at the bottom of the elevator car, and a counterweight mechanism is connected on the elevator car. The counterweight mechanism includes a counterweight block, which is connected with the elevator car through a steel cable, the counterweight block is connected with the counterweight guide rail through the counterweight guide shoe, and the counterweight guide rail is fixed with the elevator shaft through the counterweight bracket. [0003] The elevator control cabinet is used for installing control elements, and the user can control the elevator car to reach a designated floor through the control elements installed in the elevator control cabinet. The structure of the elevator control cabinet includes a bottom box and a cabinet door. Floor ...

AI Technical Summary

Problems solved by technology

Due to the high position of the counterweight bracket and poor welding working conditions, it is difficult to install the counterweight bracket; because the counterweight bracket is formed by welding and the working conditions during welding are poor, and the welding skills of the workers are uneven, resulting in guide rails The welding quality between the mounting plate and the bottom plate is difficult to guarantee, and the welding strength may not be enough

In addition, when the guide rail mounting plate is welded to the bottom plate, the metal surface coating will be damaged, making the counterweight bracket easy to rust, especially in a relatively dark and humid elevator shaft, which will easily reduce the strength of the counterweight bracket and cause fracture. The guide rail cannot be fixed, causing the elevator car to shake, and the safety of the elevator car is reduced

[0006] In summary, due to certain defects in the structure of the existing elevator control cabinet, elevator lower beam and counterweight support, the existing elevator car has defects such as difficult maintenance, low safety, low production efficiency and high cost
