Abstract

The invention discloses a verification device for a crane monitoring system. The verification device comprises a crane moving mechanism for simulating crane movement and braking, a simulated heavy object mechanism for simulating crane lifting loads, and a lateral simulated wind mechanism for simulating lateral wind force, wherein the simulated heavy object mechanism is installed on crane moving mechanism, one side of the crane moving mechanism is provided with the lateral simulated wind mechanism, the lateral simulated wind mechanism is connected to a simulated wind direction mechanism, the front end of the simulated wind direction mechanism is provided with a control panel, and the rear end of the crane moving mechanism is provided with a detection displacement mechanism for detecting displacement. The verification device has a reasonable structure, can improve the credibility of detection and verification by using the lateral simulated wind mechanism and the simulated wind directionmechanism to simulate the lateral wind force in various directions, the displacement effect and displacement difference of the crane moving mechanism can be accurately and directly observed by using the detection displacement mechanism, and the detection and verification effect is improved

Description

technical field [0001] The invention relates to the field of crane monitoring, in particular to a crane monitoring system verification device. Background technique [0002] Gantry crane (also known as gantry crane) is a bridge type crane whose bridge frame is supported on the ground track by the outriggers on both sides. Structurally, it consists of a mast, a cart running mechanism, a lifting trolley and electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported to run on the factory building or trestle, called semi-gantry cranes. The gantry crane's upper bridge frame (including the main girder and end girder), outriggers, and lower beams are composed of parts. In order to expand the working range of the crane, the main girder can extend out of the outriggers to one or both sides to form a cantilever. A trolley with a jib can also be used to expand the working range of the crane through the pitch and rotation of the jib. [000...

Problems solved by technology

However, there is currently a lack of effective verification methods for the crane monitoring system. For example, the brakes of the gantry crane can avoid the effect of lateral sliding. However, due to the uncertain factors of the external environment, it is necessary to perform anti-skid detection and verification on the braking performance of the crane. In order to avoid accidents in practical applications, the general verification device uses an ordinary horizontal thrust device to simulate the wind direction, which cannot effectively simulate the lateral wind force and the displacement effect is observed by human eyes, and the test data is inaccurate
