A connecting bridge arranged on a sucker is provided with a guide cylinder body welded with the connecting bridge of the sucker; the guide cylinder body is provided with holes on front and rear side; the insides of a front opening and a rear opening of the guide cylinder body are provided with a propeller; the propeller consists of an impeller and an impeller shaft, wherein the impeller shaft and the lengthwise direction of the bridge are in vertical arrangement; two ends of impeller shaft are fixed with the inner wall of the guide cylinder body respectively through a front bracket and a rear bracket by a front bearing seat and a rear bearing seat; and the impeller shaft is connected with a hydraulic motor. The steering propulsion device does not need a traction mechanism or does not need to anchor; the range of the steering displacement of the sucker can reach any angle; and in the positioning state of the same positioning pile, the mud suction boat enlarges the working range by more than three times compared with the prior mud suction boat using the anchoring operation, has flexible rotation and greatly improves the working efficiency.
Description
Technical field
The present invention relates to excavation, dredging technology field, especially relate 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 objective of the invention is provides a kind of steering propulsion unit of suction head of suction dredger for overcoming the deficiency of prior art, does 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, technical scheme of the present invention 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 invention 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 invention, 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.
