Problems solved by technology

[0005] (1) Due to the different needs of customers, the elevator components are very different, and the calculation of each project is very heavy for the design workload
[0006] (2) The proportion of customer customization demand in the market has increased, and the proportion of secondary decoration in the later stage has increased. The design stage cannot fully consider the balance of the customer's secondary decoration components in the later stage, resulting in poor balance of the actual project
[0007] (3) In order to avoid the problems caused by the defect (2), the design margin and safety factor of the components need to be enlarged, resulting in an increase in the manufacturing cost of the components

Abstract

The invention discloses an auxiliary tool for balance adjustment of a lift car. The auxiliary tool comprises a base and an adjustment assembly. A Y-direction adjustment assembly is assembled on the transverse face of the base, and an X-negative-direction adjustment assembly and an X-positive-direction adjustment assembly are installed on the two vertical faces of the base respectively. The adjustment assembly is provided with an elastic component and an elastic force indication component. The elastic component of the Y-direction adjustment assembly deforms when stressed in the Y direction, and the elastic force indication component of the Y-direction adjustment assembly reflects the deformation force of the elastic component of the Y-direction adjustment assembly. The elastic component of the X-negative-direction adjustment assembly and the elastic component of the X-positive-direction adjustment assembly deform when stressed in the X direction, and the elastic force indication component of the X-negative-direction adjustment assembly reflects the deformation force of the corresponding elastic component. According to the auxiliary tool, balance adjustment of the lift car can be conveniently conducted after an elevator is installed, and the cost is low.

Description

technical field [0001] The invention relates to an elevator installation auxiliary tool, in particular to an auxiliary car balance adjustment tool. Background technique [0002] In order to improve the comfort of the elevator and reduce the cost of components, the elevator needs to be balanced in the design of the elevator. [0003] At present, the mainstream method is to calculate the weight of each part of the elevator in the middle of the hoistway and the distance between the part and the hoisting center in the design stage, and after obtaining the overall eccentric moment of the car, offset the moment by adding a counterweight at the opposite position of the positive moment. To achieve the overall balance of the elevator car. [0004] The flaws in this method are: [0005] (1) Due to the different needs of customers, the elevator components are very different, and the calculation of each project is very heavy for the design workload. [0006] (2) The proportion of cus...
