Fence type drum shore bridge pitching mechanism

Abstract

The invention relates to a fence type drum shore bridge pitching mechanism. The shore bridge pitching mechanism is provided with a fence type drum, a planetary reducer and a motor, wherein the fence type drum is provided with a double-folding line rope groove and a radial plate; the radial plate is provided with a carving table; the double-folding line rope groove encircles the fence type drum; a low-speed grade brake is additionally arranged at the end, far from the motor, of the fence type drum; the planetary reducer is connected with a low-speed shaft and a high-speed shaft; the low-speed shaft and the high-speed shaft are coaxial; a high-speed grade brake is arranged beside the high-speed shaft; the high-speed shaft is connected with an output shaft of the motor through a motor coupling; the low-speed shaft is connected with an outlet shaft at one end of the fence type drum through a drum coupling; the outlet shaft is positioned in the center of the end surface of the fence type drum; a bearing base is arranged on the end surface of the fence type drum; and the outlet shaft is positioned in the bearing base. The fence type drum shore bridge pitching mechanism has the advantages of obvious increment of rope volume of the drum, effective reduction of space volume, long service life, light weight and compact structure.

Description

technical field [0001] The invention relates to the field of crane machinery, in particular to a pitching mechanism of a fence-type reel-to-quay bridge. Background technique [0002] Regarding the crane for hoisting containers on the shore, the mechanism responsible for lifting and lowering the front girder around the hinge point of the girder is called the quay crane pitching mechanism, which is driven by a motor, through a coupling, and through a transmission device such as a reducer to drive the wire rope drum to roll. Rotate motion to achieve pitch motion. [0003] In the prior art, the usual layout of the pitching mechanism of the quay crane is a base-fixed reducer 84, the high-speed shaft 81 of which is connected to the motor 8, and the low-speed shaft 82 is connected to a common reel 83 wound in a single layer (see figure 1 and figure 2 ). However, the quay crane pitching mechanism in the prior art has the following disadvantages: first, because the ordinary reel ...

AI Technical Summary

Problems solved by technology

However, the quay crane pitching mechanism in the prior art has the following disadvantages: first, because the ordinary reel 83 is wound in a single layer, the rope capacity is limited, and in order to ensure that the deflection angle of the steel wire rope leaving the ordinary reel 83 rope groove meets the requirements, Therefore, the diameter of the ordinary reel 83 is relatively large, generally more than one meter; secondly, the motor 8 and the ordinary reel 83 are respectively connected to the high-speed shaft 81 and the low-speed shaft 82 of the reducer 84, and are not on the same straight line, and the reducer 84 is relatively large in volume. , the volume of the entire quay crane pitching mechanism is relatively large, resulting in a corresponding increase in the volume of the quay crane pitching mechanism base and the machine room

There is no report about the pitching mechanism of the quay crane that can solve the above technical problems
