Windproof sliding simulation system for crane under circumstance of deviation of center of gravity

Abstract

The invention relates to a windproof sliding simulation system for a crane under a circumstance of a deviation of the center of gravity. The system includes two parallel tracks and a test trolley, two of four rollers that the test trolley is provided with are arranged on one of the two tracks, the other two rollers are arranged on the other track, the system also includes an elastic traction device, an interval of the two tracks is adjustable, a carrying platform arranged at the upper part of the test trolley is provided with a telescopic structure in a width direction, a plurality of balancing weight fixing seats are arranged on the carrying platform, and braking devices are arranged on the rollers. Weight is added to a vertical direction of the test trolley by adoption of the balancing weights, and a load of the crane is simulated, compared with adoption of an oil cylinder in the vertical direction to perform pressurization, the structure is simplified, and movement of the test trolley is not excessively restricted; flexible tractive force is applied to the test trolley by adoption of traction chains; and the structure of the guide rails with an adjustable relative interval and the telescopic carrying platform enables the test trolley to simulate brake performance, overturn tendency and the like of portal cranes of different widths.

Description

technical field [0001] The invention relates to a wind resistance simulation test device, in particular to a wind resistance sliding simulation system when the center of gravity of a crane deviates. Background technique [0002] With the vigorous development of port loading and unloading transportation industry, large port machinery equipment is playing an increasingly important role in the modern production of ports. However, due to its tall structure and large windward area, it is easy to be attacked by wind force when a typhoon or sudden gust occurs. Therefore, the windproof work of large-scale machinery at seaport terminals plays a very important role in production safety. Large-scale logistics equipment-hoisting machinery working in the open air are required to be equipped with suitable wind-resistant and anti-skid devices to avoid major personal injuries and property loss accidents when hit by typhoons and sudden gusts of wind. The wind resistance and anti-skid abilit...

[0005] The patent name is: Invention patent of indoor test and detection device for wind-resistant and anti-skid brakes of port cranes, ZL201210104398.4, which discloses that the technical solution adopts vertical loading cylinders, which limits the detection movement and makes the structure extremely complicated. The push force, length, and duration of the platform are limited, and it is not possible to do complex detection, especially high-speed operation detection
