Problems solved by technology

[0002] In order to meet the calculation requirements of the traction force of the elevator, the conventional methods in the design of the elevator are: 1) aggravate the compensation chain, and use the compensation method to meet the calculation requirements of the traction force; 2) through the car (especially the car frame) profile or plate parts Thickened to achieve the purpose of weighting the car; 3) By means of the balance iron to adjust the force balance of the elevator, but due to the eccentric suspension, it needs to be symmetrically arranged, and the on-site installation and adjustment are more troublesome
In addition, the above three solutions also have one thing in common: the production cost is relatively high

Abstract

The invention relates to an elevator car frame structure. The elevator car frame structure comprises a car frame upper beam assembly, counterweight assemblies, guide shoes, oil cups, a car frame lower beam assembly, car frame vertical beam assemblies used for connecting the car frame upper beam assembly and the car frame lower beam assembly and safety tongs; and the counterweight assemblies are arranged in an inner cavity of the car frame upper beam assembly or an inner cavity of the car frame lower beam assembly, the plane where the lowest ends of the counterweight assemblies are located is higher than the plane where the lowest ends of the car frame upper beam assembly and the car frame lower beam assembly are located, and the plane where the highest ends of the counterweight assemblies are located is higher than the plane where the highest ends of the car frame upper beam assembly and the car frame lower beam assembly are located. According to the elevator car frame structure, a plurality of counterweight iron assemblies can be placed according to the requirement of a weighted car, the unbalance loading influence on the car is avoided, the price is low while the dead weight of the car is increased, and the device can be widely applied to various elevator products with insufficient dead weight of the cars.

Description

technical field [0001] The invention relates to an elevator structure, in particular to a car frame structure of an elevator car. Background technique [0002] In order to meet the calculation requirements of the traction force of the elevator, the conventional methods in the design of the elevator are: 1) aggravate the compensation chain, and use the compensation method to meet the calculation requirements of the traction force; 2) through the car (especially the car frame) profile or plate parts Thickened to achieve the purpose of increasing the weight of the car; 3) by means of the balance iron to adjust the force balance of the elevator, but due to the use of eccentric suspension, it needs to be symmetrically arranged, and the on-site installation and adjustment are more troublesome. In addition, the above three solutions also have one thing in common: the production cost is relatively high. Contents of the invention [0003] In order to solve the deficiencies in the ...
