Weight loading device for lift security element detection

Abstract

The invention discloses a weight loading device for lift security element detection. The weight loading device comprises a hook lifting mechanism, a lateral movable rack, a longitudinal movable rack and a bottom frame, wherein the hook lifting mechanism is connected with the bottom of the lateral movable rack in a sliding manner; the top of the lateral movable rack is connected with the longitudinal movable rack in a sliding manner; the bottom of the longitudinal movable rack is connected with the bottom frame in a sliding manner; the hook lifting mechanism moves longitudinally along the lateral movable rack; the lateral movable rack moves laterally along the longitudinal movable rack; the longitudinal movable rack moves longitudinally along the bottom frame. When the weight loading device is used on lift security element detection equipment, the weight loading device can totally replace the traditional manual handling and realizes mechanized loading and unloading of weights, so that the loading and unloading efficiency is effectively improved, manual operations are reduced, and the safety of operators is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of detection equipment for elevator safety components, in particular to a weight loading device for detection of elevator safety components. Background technique [0002] In the testing process of elevator safety components, weights are often placed in the test frame to simulate a fully loaded elevator car for testing. In traditional detection devices, the weights are put in by manual handling. For some large-scale safety components (such as safety gear), the maximum test load needs to be more than ten tons or even tens of tons. Manual handling is not only cumbersome , The loading efficiency is low, and the safety of the operators is difficult to be better guaranteed. For the manual handling method, considering the limited human strength, the mass of a single weight cannot be made relatively large. In large-mass tests, the number of weights required is large and it is difficult to fix. If the fixation is unstable, it...

In traditional detection devices, the weights are put in by manual handling. For some large-scale safety components (such as safety gear), the maximum test load needs to be more than ten tons or even tens of tons. Manual handling is not only cumbersome , Loading efficiency is low, and it is difficult to ensure the safety of operators at the same time

For the manual handling method, considering the limited human strength, the mass of a single weight cannot be made relatively large. In large-mass tests, the number of weights required is large and it is difficult to fix. If the fixation is unstable, it will affect test results
