Hough hinge capable of adjusting level angle and lateral displacement of trolley

Abstract

The invention discloses a hough hinge capable of adjusting a level angle and a lateral displacement of a trolley. The hough hinge comprises a hinge shaft. Outer parts of two ends of the hinge shaft are respectively provided with an upper hinged support and a lower hinged support. The hinge shaft is arranged in the upper hinged support and the lower hinged support. A lantern ring is sleeved on outer ends of the upper hinged support and the lower hinged support so that the upper hinged support and the lower hinged support are fixed with each other. Covers are fixed to two end surfaces of the hinge shaft respectively by bolts. The hough hinge is characterized in that two sides of the top of the upper hinged support and / or two sides of the bottom of the lower hinged support respectively and radially extend outward to form side plates; each one of the side plates is provided with a through-hole; bolts pass through the through-holes; the through-hole surrounds a bolt track; and positions of the bolts can be adjusted freely. The lower hinged support is fixed to the trolley by a bolt fixing method and thus new homotopic difference and corner difference are not produced by welding thermal deformation. A level angle and a lateral displacement of the trolley can be adjusted by adjusting positions of the bolts in the long through-holes of the lower hinged support so that rail gnawing is prevented.

Description

technical field [0001] The invention relates to a Hough hinge for connecting a trolley and a small balance beam in a crane, in particular to a Hough hinge which can adjust the horizontal rotation angle and lateral displacement of the trolley. Background technique [0002] The cart traveling mechanism of shipbuilding gantry cranes, gantry cranes, large bridge cranes, and shoreside container loading and unloading bridges all need to use multiple groups of trolleys and small balance beams. Adopt conventional Huff hinge connection. The Huff hinge includes an upper hinge seat and a lower hinge seat. The upper hinge seat of the Huff hinge is welded and fixed to the small balance beam, the lower hinge seat is welded and fixed to the trolley, and the hinge shaft is connected in the middle to realize the hinge function to compensate for the level of the cart track. error and distribute the wheel pressure evenly on each wheel. [0003] Since the upper and lower seats of the Huff hin...

AI Technical Summary

Problems solved by technology

[0005] Due to its structural defects, the traditional Huff hinge cannot realize the horizontal angle adjustment and lateral displacement adjustment of the trolley, unless the upper hinge seat or the lower hinge seat of the Huff hinge is cut off, and then the position of the trolley is readjusted to meet the specification requirements

However, after the adjustment, it needs to be fixed by welding, which will cause a new difference in the same position and rotation angle due to the thermal deformation of the welding.

Therefore, the existing technical solutions bring great difficulties to the adjustment, and the cost and rectification period of the adjustment are relatively long
