Description
Technical field
The utility model relates to excavation, dredging technology field, especially relates to the steering propulsion unit of suction head of suction dredger.
Background technology
Soil-suction head on the hydraulic suction dredge moves to another place finishing need turn after mud is inhaled at a place, so soil-suction head need constantly turn to displacement in the course of the work, like this along with hull moves, the suction mud task in whole zone could be finished; The displacement that turns to of soil-suction head spurs by haulage gear on the present domestic hydraulic suction dredge, spur soil-suction head and make it to turn to displacement, must be equipped with hoist engine on the ship, and wire rope is fixed on the soil-suction head; Simultaneously, need first riding at anchor when turning to displacement, frequent casting anchor, weigh anchor need expend a large amount of time at every turn; And, the displacement range that turns to of soil-suction head is restricted because the anchor position can influence the rotational angle of soil-suction head.
Summary of the invention
The purpose of this utility model is for overcoming the deficiency of prior art, a kind of steering propulsion unit of suction head of suction dredger is provided, do not need haulage gear, also needn't riding at anchor, soil-suction head turn to displacement range big, rotate flexibly high efficiency.
For achieving the above object, the technical solution of the utility model is such: a kind of steering propulsion unit of suction head of suction dredger, be installed on the connection crane span structure of suction nozzle, and comprise and the propeller that is provided with in suction nozzle connects stream guiding barrel that crane span structure welds mutually, stream guiding barrel; Said propeller is made up of impeller and impeller shaft; The wherein vertical vertical setting of impeller shaft and crane span structure; The bearing support at these impeller shaft two ends fixes by support and stream guiding barrel inwall; Impeller shaft connects hydraulic motor.
The course of work of the present utility model is such: during work, hydraulic suction dredge is by off-position stake control and adjusting accommodation, and suction nozzle is behind operation certain angle under the propeller effect, and the manipulation propeller drives and reverses, and stake is changed in the off-position stake synchronously, finishes displacement at any time; Because propeller is by fluid motor-driven, the forwards that can fall advances, and handiness when meeting that the silt bedding is uneven under water, can advance suction nozzle by neutral gear fast, can not occur moving complicated, stiff like that by the hoist engine traction; When meeting the variation of cement mortar bulk concentration, can regulate the propeller dynamics at any time neatly, thereby reach best job state.
Owing to adopted technique scheme, the steering propulsion unit of a kind of suction head of suction dredger of the present utility model, do not need haulage gear, also needn't riding at anchor, the displacement range that turns to of suction nozzle can reach arbitrarily angled, hydraulic suction dredge has enlarged more than three times than the cast anchor working range of operation of former use under same guide pile positioning states, and rotates flexibly, and operating efficiency improves greatly.
