Description

Cart running gear and torsion-resistant assembly thereof

Technical Field

The utility model relates to the field of shore bridges and ship unloaders, in particular to a cart traveling device and an anti-torsion assembly thereof.

Background

Along with the strong increase of global freight demand, container ro-ro ships and bulk carriers are also developed in large scale, and in order to meet the demand of wharf cargo throughput, the specifications of shore bridges and ship unloaders are required to be increased continuously. However, due to limited bearing capacity of the user dock, such as increased specifications of the quay crane and the ship unloader, the conventional symmetrical eight-wheel cart travelling mechanism often exceeds the permission of dock wheel pressure.

When a larger-specification shore bridge and a ship unloader are designed, in order to meet the wheel pressure permission of a user wharf, the conventional cart running mechanism is often designed into an asymmetric ten-wheel mechanism to reduce the wheel pressure. The asymmetric travelling mechanism is arranged in a non-central symmetry manner along the length direction of the travelling mechanism, and the travelling wheel layout below the travelling mechanism is arranged in a non-central symmetry manner.

However, when the asymmetric ten-wheel mechanism walks and the wharf is over-connected and towed after the shore bridge and the ship unloader are assembled together, the towing support is installed to be biased to the inner side due to the asymmetry of the travelling mechanism, and larger torsion is generated when the whole is over-connected and tensioned, so that the bolts, the large balance beam shaft and the travelling connecting support on the travelling flange are damaged.
