Deflection-preventive vibration avoiding system for high-speed quay crane trolley

Abstract

The invention discloses a deflection-preventive vibration avoiding system for a high-speed quay crane trolley. The deflection-preventive vibration avoiding system comprises a plurality of vibration avoiding devices, wherein the each vibration avoiding device comprises a connecting base and an oil-gas damper; the corresponding connecting base is fixedly arranged on a framework of the quay crane trolley; the corresponding oil-gas damper is horizontally arranged between the framework of the quay crane trolley and a support of a deflection-preventive wheel; and the corresponding connecting base is hinged to one end of the oil-gas damper, and the support of the deflection-preventive wheel is fixedly connected to the other end of the corresponding oil-gas damper. According to the deflection-preventive vibration avoiding system disclosed by the invention, transverse vibration of the deflection-preventive wheel of the quay crane trolley is reduced, collision and extrusion between the deflection-preventive wheel and rails which are arranged on a quay crane large beam can be prevented, steady operation of the quay crane trolley is ensured, and the quay crane trolley and the quay crane structure can be protected, so that the operation speed of the quay crane trolley is further improved, and the loading and unloading efficiency of the quay crane is improved. Meanwhile, by utilizing common effect of the oil-gas damper and a rubber damper, the working performance cannot be prevented even if the oil-gas damper is too heat, and the problems of less rigidity and large deformation of rubber springs also can be overcome.

Description

technical field [0001] The invention relates to the technical field of container loading and unloading equipment in port terminals, in particular to a high-speed quay crane trolley anti-deviation wheel vibration-isolating system. Background technique [0002] Ocean transportation is the most important mode of transportation in international logistics. Large ships are used to transport goods between ports. The cost of ocean transportation is low and the volume of transportation is huge. Two-thirds of the transportation volume in international logistics is completed by ocean transportation. About 90% of the total import and export freight depends on ocean transportation. The port terminal is a transfer station for ocean transportation and land transportation, and container ships need to complete loading and unloading at the port. The rapid development of the world economy has driven the development of international logistics, and the total amount of freight has also increased...

AI Technical Summary

Problems solved by technology

When the horizontal fine-tuning position of the container is lifted and placed or when it is affected by external factors, the quay crane trolley may experience lateral vibration. It is more serious when the trolley runs at high speed, which limits the speed-up of the quay crane trolley. Therefore, it is necessary to develop a vibration-absorbing system that can reduce the collision between the anti-deflection wheel of the quay crane trolley and the track.
