Trolley device for hydraulic ship unloader

Abstract

The invention provides a trolley device for a hydraulic ship unloader. The trolley device comprises a trolley, a steel wire rope system, a track and a winch, the winch is fixed to the rear end of a boom of the ship unloader, the track is fixed below the front section of the boom, a frame of the trolley can move along the track, the frame is provided with a slurry pump connected to the frame, the steel wire rope system comprises a steel wire rope, a pulley block and a ratchet mechanism, one end of the steel wire rope is wound around the winch after bypassing the pulley block, the other end of the steel wire rope is connected to the ratchet mechanism, the ratchet mechanism is connected to the trolley, and the winch drives the steel wire rope to enable the trolley to move along the track so as to drive the slurry pump to stably move along the boom. Compared with a traditional mobile ship unloader, the trolley device has the advantages that a trolley running mechanism is additionally arranged, the slurry pump moves in the direction of the boom and is matched with the rotary motion of the ship unloader, full-cabin covering of the slurry pump is achieved, the covering area of a material taking point in a cabin is enlarged, the purposes of efficient ship unloading and rapid cabin cleaning are achieved, and the trolley device is a very good choice for the mobile ship unloader.

Description

technical field [0001] The invention relates to the technical field of ship unloaders, in particular to a trolley device for a hydraulic ship unloader. Background technique [0002] Mobile ship unloader is the terminal equipment of large bulk material terminal, which plays an increasingly important role in energy, electric power, metallurgy, port and other industries, and directly determines the production capacity of the terminal. The "Rotary Hydraulic Ship Unloader" with the publication number CN106429532A discloses a new type of ship unloader, which can adapt to the unloading operation of materials with fine particles, high moisture and high density, and solve the problems of poor environmental protection and unloading in the prior art. The problem of long ship cycle. [0003] The trolley device in the above-mentioned ship unloader is the main mechanism of the mobile ship unloader, and performs the function of retrieving and repositioning the mud pump. Its moving functio...

AI Technical Summary

Problems solved by technology

The conventional mobile ship unloader usually adopts an integral arm frame. The arm frame itself does not have telescopic function and there is no trolley device on the arm frame. It can only realize transposition retrieving through the rotary mechanism. The retrieving point cannot cover the entire cabin, resulting in The material cannot be completely cleared, which greatly affects the unloading efficiency
