Comprehensive laboratory examination device for anti-wind brake product of crane

Abstract

The invention relates to a comprehensive laboratory examination device for an anti-wind brake product of a crane. The comprehensive laboratory examination device for the anti-wind brake product of the crane comprises a base, a roller way is fixed on the base, a roller way sliding plate is movably arranged on the roller way, and the roller way is fixedly connected with the roller way sliding plate through a pressure plate; an experiment trolley composed of a trolley frame and wheel parts is mounted on the roller way, the bottom of a sliding type pressing rack is hinged to the trolley frame, a pair of wheel-pressure simulation oil cylinders are fixed at the top of the sliding type pressing rack, the tops of the wheel-pressure simulation oil cylinders are connected with a pulley in a butting manner, and the pulley is connected in a sliding manner with the lower end surface of the top of a test bench frame through two sets of double carrier rollers. The comprehensive laboratory examination device provided by the invention has a simple structure, is convenient to use, can simulate the wheel pressure of a walking wheel and the wind load of an outdoor crane inside a laboratory, and also can detect dynamic and static windproof resistance and friction performance of the anti-wind brake product (such as a wheel brake, a rail clamping device and a rail brake) of the crane on a normal rail surface or a rail surface with water, oil, sand and the like.

Description

technical field [0001] The invention relates to a crane windproof brake product detection device, in particular to a comprehensive crane windproof brake product laboratory detection device. Background technique [0002] Lifting and unloading machinery working outdoors (especially large-scale professional lifting and unloading machinery used in the open air such as large ports and wharfs with a large structural volume and large windward area) often encounter sudden strong winds when working in the work area , so these lifting and handling machinery generally need to be equipped with windproof devices under working conditions. The reliability and windproof effect of the windproof device directly affect the operation safety of the lifting and unloading machinery. If the reliability of the windproof device and the windproof braking effect cannot meet the requirements, when the lifting and unloading machinery encounters sudden strong winds during work, The lifting and unloading ...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic windproof brake device manufacturers lack special devices for testing the performance of windproof brake device products, and can only conduct some on-site tests, that is, use large tractor vehicles to tow the entire crane (the windproof brake device is in the braking state), Until the crane cart moves, and then detect and calculate the size of the wind resistance of the crane through the tension sensor, the test device is complex, the cost is very high, and the stability of the test effect is poor
