Abstract

The invention discloses a method and a system of detection of a lifting device. The method comprises the following steps that real-time pressure information of a disc spring in a lifting device is acquired; force adjusting information of a force adjusting nut in the lifting device is obtained, and the deformation information of the corresponding disc spring is obtained according to the force adjusting information; and the corresponding target pressure information is calculated according to a preset disc spring variable force curve and the deformation information; the force adjusting nut is adjusted according to the real-time pressure information and the target pressure information until the difference value of the real-time pressure information and the target pressure information is smaller than or equal to a preset error threshold value. The method and the system for detecting the lifting device provided by the embodiment of the invention, a braking force of a buffer is acquired by detecting the real-time pressure information of the disc spring in the lifting device, an unhooking test is avoided, so that the braking force level of the lifting device can be conveniently and rapidlyknown, the lifting device with insufficient braking force can be maintained in time, and the safe and reliable operation of the lifting device can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of lifting devices, in particular to a detection method and system for a lifting device. Background technique [0002] Existing hoisting devices, such as shaft hoisting anti-overwinding (over-discharging) devices, cannot obtain the braking force of the buffer in real time, so that the maintenance of the buffer cannot be carried out in time, thus burying hidden dangers for the safe operation of the hoisting device. [0003] In addition, the existing hoisting device is very cumbersome to obtain relevant data such as buffer braking force, and needs to suspend the equipment, which is inefficient. In the prior art, it is first necessary to obtain the braking force of the buffer at different heights of the cage of the lifting device through multiple experiments; secondly, obtain the degree of tightness of the adjusting nut when the cage is at different heights, and finally according to the degree of tightness of t...
