Self-propulsion type concrete mixing ship

Abstract

The invention relates to a self- propulsion type concrete mixing ship. In the invention, the front part of an inner cabin of a deep-cabin cargo ship is provided with an aggregate bin, and the back side of the aggregate bin is provided with a grappling bucket hanger; the middle part of the inner bin of the deep-cabin cargo ship is provided with a proportioning machine, a water storage tank, a concrete stirrer, a water reducing agent tank and a concrete transportation pump; and the back part of the inner bin of the deep-cabin cargo ship is provided with an integral type steel sealed filler bin, a discharge port at the bottom of the steel sealed filler bin is connected with a feeding mechanism of a first spiral conveyer, a discharge pipe at the back end of the first spiral conveyer is connected with a feed pipe at the front end of a second spiral conveyer, and a discharge pipe at the back end of the second spiral conveyer is positioned above a measuring hopper at the top part of the concrete stirrer. The invention reasonably arranges various kinds of concrete mixing equipment in the deep-cabin cargo ship, is an integrative self-propelled type mixing ship integrating the storage, the metering, the transportation, the stirring and the pumping of raw materials, such as aggregates, powder, water, an admixture and the like, can meet the basic requirement that stock preparation of one time can pour for large square quantity, and has the characteristics of overwater maneuvering flexibility, independent voyage, quick positioning, large production capacity of concrete, good stability, low cost input and the like.

Description

technical field [0001] The invention belongs to the field of ships, in particular to a self-propelled concrete mixing ship. Background technique [0002] In recent years, with the continuous expansion of the national infrastructure project construction scale, the degree of mechanization of construction enterprises has been expanding, and the construction environment faced by construction units has also diversified. By extension, some large-scale construction projects have unavoidable water construction, and the project has a combination of land and water construction, or is completely water (sea) construction. Therefore, there is a demand for a water mixing plant and a concrete mixing vessel with good mobility and low price in the construction engineering market. Chinese patent ZL 200420021650.6 announced on April 13, 2005 a concrete mixing vessel. A hopper bin is arranged on the middle deck of the ship. The hopper bin includes an aggregate weighing device and a mobile open...

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
