Problems solved by technology

[0003] The running speed of the quay crane trolley is affected by many factors. The quay crane trolley itself is heavy and has a large gauge. At the same time, the quay crane is a cantilever structure with both ends extending outward. Vibration occurs due to factors such as take-off and landing, inertial loads, and the external environment. When the quay crane trolley and the quay crane trolley spreader run too fast, the vibration amplitude increases, which cannot guarantee the safety of the quay crane operation.
Excessive vibration of the quay crane trolley will also cause repeated collisions between the quay crane trolley, the quay bridge girder and the quay bridge structure, wear and squeeze the track of the quay crane trolley, seriously affect the service life of the quay bridge, and increase safety hazards
At present, the movement speed of the quay crane trolley along the girder of the quay bridge has been increased to 240m / min, and the hoisting speed of the quay crane trolley spreader in the vertical direction under heavy load conditions has been increased to 75m / min, but in the existing quay bridge structure and Under the working environment, the speed of the quay crane trolley has reached the limit and cannot continue to increase

Abstract

The invention discloses a vibration avoiding system for a high-speed quay crane trolley. The vibration avoiding system comprises a quay crane trolley vehicle frame, a wheel vibration avoiding system, a deflection-preventive wheel vibration avoiding system and a traction wheel vibration avoiding system, wherein the wheel vibration avoiding system comprises trolley wheels and a wheel vibration avoiding device; the deflection-preventive wheel vibration avoiding system comprises deflection-preventive wheels, a deflection-preventive wheel support and a deflection-preventive wheel vibration avoiding device; and the traction wheel vibration avoiding system comprises traction wheels, traction wheel supports and a traction wheel vibration avoiding device. According to the vibration avoiding system disclosed by the invention, the vibration amplitudes of the quay crane moving at high speed in the extending direction of a quay crane large beam, the direction being perpendicular to the extending direction of the quay crane large beam in the horizontal plane and in the vertical direction of the quay crane large beam are weakened, the quay crane trolley can stably run, extrusion and collision between the quay crane trolley and the quay crane large beam can be weakened, and the service life of the quay crane trolley and the quay crane structure is prolonged, so that conditions are created for further increasing the speed of the quay crane trolley, and the loading and unloading efficiency of containers on the quay crane can be improved.

Description

technical field [0001] The invention relates to the technical field of container loading and unloading equipment at ports and wharfs, in particular to a vibration-absorbing system for high-speed quay crane trolleys. Background technique [0002] As the most important container handling equipment in the port terminal, the loading and unloading efficiency of the quay crane directly affects the working efficiency and operating cost of the port terminal. The quay crane uses a trolley that moves along the girder of the quay bridge to complete the lifting, transfer and placement of the container. The running speed of the quay bridge trolley along the girder of the quay bridge and the running speed of the spreader of the quay bridge trolley in the vertical direction are directly related to the loading and unloading efficiency of the quay crane , the shore bridge trolley has also undergone multiple accelerations. [0003] The running speed of the quay crane trolley is affected by m...
