Elevator lifting rope detection device and tension detection method

Abstract

The invention aims to provide a rope detection device for elevator lifting, which can effectively avoid the influence of human factors and judge and detect the working state of an elevator rope, and a detection method for further measuring and calculating the tensile force on the rope by using the device. The rope detection device for elevator lifting comprises an acting force applying mechanism which is used for applying an acting force to a local position point of the rope for elevator lifting to enable the stress position point of the rope for elevator lifting to displace when a detection person operates the rope detection device. The variable detection system is used for detecting related numerical values capable of reflecting the internal tension condition of the rope for elevator lifting in the moving process of the position point, and the variable detection system comprises an acting force magnitude detection unit, an acting force direction detection unit and a force bearing point displacement detection unit.

Description

technical field [0001] The invention relates to the field of vertical lifting elevator equipment, in particular to a rope detection device and a tension detection method for elevator lifting. Background technique [0002] Vertical lift elevator equipment has been widely used in various high-rise buildings as an indispensable equipment due to its advantages such as high carrying capacity, space saving and cost controllable. Because in this type of elevator equipment, the main body of the elevator car is mostly connected to the upper traction sheave by a cable braided by steel wires, and realizes the function of lifting and moving under the drive of the traction sheave. During use, the steel rope bears the entire weight of the elevator car, especially the section between the elevator car and the traction sheave, which will be in a tense state for a long time. Therefore, it is necessary to regularly detect the mechanical properties of the rope to prevent it from breaking and r...

Problems solved by technology

However, during the detection process using the above-mentioned rope detection device for elevators, due to the influence of factors such as the unstable pulling direction of the user or the shaking of the rope itself, it will result in the force applied to the elevator rope when obtaining the corresponding lateral pulling force and displacement. The direction of the force on the cable cannot be guaranteed to be along the horizontal direction, that is, a part of the force recorded as the lateral pull force actually becomes the pull force in the vertical direction of the rope, which leads to inaccurate data calculation.

In addition, when testing different ropes, due to the different degrees of deviation of the lateral tension relative to the horizontal direction, the error of the obtained data will be further amplified, which will seriously affect the accuracy of the testing results.
