Description

Self-adaptive hinge point support and ship unloader

Technical Field

The utility model relates to the technical field of port loading and unloading equipment, in particular to a self-adaptive hinge point support and a ship unloader.

Background

In order to meet the requirements of ship landing and departure, the front cantilever of the port ship unloader needs to be provided with a pitching device so as to realize lifting or falling of the front cantilever. The pitching device is provided with a hinge point support at the junction of the front girder and the rear girder, so that the front cantilever rotates around a hinge shaft in the hinge point support under the drive of the driving mechanism, and the rotation of the front cantilever is realized.

In the prior art, as shown in fig. 1 and 2 of the specification, a front girder 01 and a rear girder 03 are rotatably connected through a hinge point support 02. The front large Liang Erban in the hinge point support 02 and the shaft sleeve 05 are welded into a whole, the hinge shaft 06 is arranged on the inner wall of the bearing 07, and the front girder 01 rotates by taking the hinge shaft 06 as the center, so that the pitching function of the front girder 01 is realized. When the front girder is in a flat arm state, the arc surface supporting blocks 08 on the front girder 01 and the plane supporting blocks 09 on the rear girder 03 are contacted with each other so as to bear positive pressure generated at the hinge joint of the front girder 01 and the rear girder 03 in the operation process of the hoisting operation mechanism. However, when the hoisting operation mechanism is operated to the overhanging portions of the front girder 01 and the rear girder 03, the relative rotation cannot be formed between the arc surface supporting block 08 and the plane supporting block 09 at the lower portion of the hinge point support 02 and the hinge point support 02, so that the supporting blocks need to bear large additional pressure. When the hoisting operation mechanism runs near the hinge point support 02, the stress at the joint of the front girder 01 and the rear girder 03 can be changed, so that the gap at the joint is changed greatly, the hoisting operation mechanism is easy to impact, and the support block is enabled to bear periodic alternating stress in a circulating way along with the circulating operation of the hoisting operation mechanism, and finally, the welding seam of the box Liang Zhijiao at the bottom of the support block is easy to form stress concentration, so that the welding seam is fatigued and damaged.

The bearing 07 usually adopts copper-based graphite bearing, and the texture is softer, and hoist and mount running gear is when the far away of hinge point support 02, near the operation of between the point, the atress of bearing 07 is inhomogeneous for bearing 07 warp easily, produces unusual sound, and the roundness error of bearing 07 is great, can't be at freely rotating along articulated shaft 06 center, causes to bite, articulated shaft 06 follow the rotation, leads to easily to fixing articulated shaft 06 axle head baffle 010's bolt torsion to cut, increases hinge point support 02's maintenance volume. In addition, since the pivot point support 02 is always subjected to the pivot point pressure, the hinge shaft 06 and the bearing 07 cannot be directly disassembled and overhauled, and the front cantilever must be lifted by a crane or a floating crane, so that the hinge shaft 06 is in a free state and overhauled, and the maintenance cost and workload are increased.

In summary, how to provide a hinge point support and a ship unloader capable of realizing adaptive adjustment is a problem to be solved by those skilled in the art.
