Gyrating centre current-collector central water device for gantry crane

Abstract

The invention discloses a gyrating centre current-collector central water device for a gantry crane. The gyrating centre current-collector central water device is characterized in that an upright water supply pipe is arranged at the centre of the space between an upper apparatus and a lower apparatus of the gantry crane, a sealing gyrating device is arranged in the middle part of the water supplypipe, and a sealing waterproof layer is arranged outside the water supply pipe and the sealing gyrating device, the water supply pipe at the upper part of the sealing gyrating device is provided with a centre current-collector bracket on which the centre current-collector is arranged, and multiple power supply circuits are mounted on the centre current-collector. The technology provides a solution to a problem of supplying water for apparatus above the gyrating mechanism of the gantry crane; meanwhile, the technology reliably isolates a water route from the electric circuits of the centre current-collector through a waterproof protection measure on the basis of preventing an original centre current-collector electric structure from being affected so as to realize the coexistence of the water supply and power supply of the upper apparatus of a gantry crane rotating column and provide the technical assurance for improving the environmental protection and dust suppression capability in the work process of the gantry crane in a harbor.

Description

Technical field:

[0001] The invention belongs to the water supply technology for port loading and unloading equipment, in particular to a central water passing device for a slewing center receiver of a gantry crane. Background technique:

[0002] Because of its versatility and high flexibility, gantry cranes are widely used in port cargo handling. When using gantry cranes to carry out coal, mineral powder, sand and gravel and other bulk cargo operations, in order to ensure that the operation process does not pollute the environment, it is necessary to carry out watering and dust suppression operations while loading and unloading the cargo. At present, bulk cargo loading and unloading terminals in ports mostly install spray guns on the storage yard and the ground of the terminal to suppress dust by spraying water on the cargo stacks. Although this method can achieve a certain effect of dust suppression, it is not capable of suppressing dust in the process of picking up and d...
