A self-propelled concrete mixer ship

Abstract

A self-propelled concrete mixing ship, the front part of the inner warehouse of the deep warehouse cargo ship is an aggregate warehouse, and the rear side of the aggregate warehouse is equipped with a grab crane; a batching machine, a water storage tank, and a concrete Mixer, water reducer tank and concrete delivery pump; an integral steel sealed powder silo is installed at the rear of the inner warehouse of the deep warehouse cargo ship, and the outlet at the bottom of the steel sealed powder silo is connected to the feeding mechanism of the first screw conveyor , the discharge pipe at the rear end of the first screw conveyor is connected to the feed pipe at the front end of the second screw conveyor, and the discharge pipe at the rear end of the second screw conveyor is located above the top measuring hopper of the concrete mixer. The present invention is a self-propelled mixing ship that integrates storage, metering, transportation, mixing and pumping of raw materials such as aggregate, powder, water and admixture by rationally arranging various concrete mixing equipment in the deep warehouse cargo ship. It can meet the basic requirements of pouring a large amount of material at one time, and has the characteristics of water maneuverability, autonomous navigation, fast positioning, large concrete production capacity, good stability, and low-cost investment.

Description

technical field [0001] The invention belongs to the field of ships, and in particular relates to a self-propelled concrete mixing ship. Background technique [0002] In recent years, with the continuous expansion of the scale of national infrastructure projects and the increasing mechanization of construction enterprises, the construction environment faced by construction units is also diversified, such as cross-sea, cross-river, and coastal ports. Extension, some large-scale construction projects are unavoidable for water construction, and the project has both land-water construction, or completely water (sea) construction. Therefore, there is a demand for a water mixing plant and a concrete mixing ship with good mobility and low price in the construction engineering market. Chinese patent ZL 200420021650.6 announced a concrete mixing ship on April 13, 2005. A hopper warehouse is set on the middle deck of the ship. The hopper warehouse includes an aggregate weighing device...

AI Technical Summary

Problems solved by technology

[0003] 1. Poor maneuverability, not self-propelled

Especially in coastal construction waters, daily concrete production requires other auxiliary ships such as large tugboats, anchor ships, material transport ships, etc. to cooperate; mobility is poor, so the transfer cost is high

[0004] 2. The construction cost of large non-self-propelled concrete mixing ships is high. Generally, deck barges are used as the mother ship platform, and the unit price of a single ship is more than 30 million yuan.

At the same time, the construction period is long and the capital investment is large

When using double sets of concrete production design, the cost investment is huge

[0005] 3. Generally, when 1 to 2 (H=50m) hydraulic booms are configured, the actual effective concrete pouring height is limited

It is generally used for pouring offshore low piers, caps, and foundation piles; when the construction pouring height exceeds 50m, it cannot meet the requirements

[0006] 4. Raw materials such as cement, fly ash, gravel, and yellow sand are fed by a belt conveyor with a large inclination angle. The structure of the belt conveyor is complex and difficult to disassemble, which is not conducive to later maintenance and cleaning of powder waste, and the cost High investment, low delivery efficiency
