Crane monitoring system verification device

Abstract

The invention discloses a crane monitoring system verification device, which includes a crane moving mechanism for simulating crane movement and braking, a simulated heavy object mechanism for simulating crane lifting heavy objects, and a lateral simulated wind force mechanism for simulated lateral wind force. The simulated heavy object mechanism is installed on the crane moving mechanism, and the lateral simulated wind mechanism is arranged on one side of the crane moving mechanism, the lateral simulated wind mechanism is connected to the simulated wind direction mechanism, and the simulated wind direction The front end of the mechanism is provided with a control panel, and the rear end of the moving mechanism of the crane is provided with a detection displacement mechanism for detecting displacement. The invention has a reasonable structure, and can use the lateral simulated wind force mechanism and the simulated wind direction mechanism to simulate the lateral wind direction force in various directions, thereby improving the reliability of detection and verification, and can observe the displacement of the crane moving mechanism more accurately and intuitively by using the displacement detection mechanism The effect and displacement are poor, 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
