Abstract
The invention discloses a method for launching an inland-river chemical carrier through an airbag, comprising the following steps: clearing sundries on a chemical carrier table; placing the chemical carrier on a bed-jig of the chemical carrier table; placing a plurality of airbags in the middle of the bed-jig; aerating 0.4Kg of air into the airbags; controlling the pressure in the airbags by observing a piezometer; heaving tightly by a steel wire rope; aerating air from the last airbag of the chemical carrier body while aerating the airbags; taking out of the bed-jig from bottom to top after the chemical carrier body leaves up while aerating; deflating the frontal airbags in sequence after all the bed-jigs are cleared out of the chemical carrier body to lead the chemical carrier body to decrease gradient; controlling the pressure of the airbag through observing the piezometer so as to control the height between the bottom of the chemical carrier and the ground; keeping that the chemical carrier body does not strand; connecting the head of the chemical carrier with a hoist; connecting the tail thereof with a tug used for dragging the chemical carrier body; dragging the chemical carrier body by the hoist through the steel wire rope to lead the chemical carrier to enter into water slowly; and recovering the airbags all of which float out of water surface after the chemical carrier body launches completely. The method of the invention has the advantages of convenient operation, time and labor saving, safety and reliability.
Description
Technical field:
The present invention relates to a kind of by air bag with the launched method of inland river chemical.
Background technology:
Nowadays, maritime works's product needed of building on horizontal slideway is loaded onto ship by slip mode, build the existing precedent of boats and ships and shipment on the horizontal slideway, but the mode that the shipment mode adopts mostly has: the one, and water under the trolley type, this method is more to the weight and the shape limitation of shipment product, so and a large amount of dollies shipment of needs costs are big, are not suitable for large-scale maritime works's product shipment; The 2nd, skid shoe type, piston shoes weight is big, is about 30 tons, and because the slippage medium of skid shoe type is wooden, friction coefficient is bigger, between 0.15～0.2, and the not reproducible use of piston shoes slippage, construction and operating cost increased, last piston shoes adopt the welding manner connection to be inconvenient to install, and cause that easily uncontrollable distortion skid shoe type is generally disposable use, and can not recycle, the shipment cost is higher relatively.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide that a kind of safety performance is good, reusable, low cost of manufacture pass through air bag with the launched method of inland river chemical.
Purpose of the present invention is achieved through the following technical solutions: a kind of by air bag with the launched method of inland river chemical, may further comprise the steps:
A, cleaning are used for placing the foreign material on the building berth of inland river chemical carrier, the inland river chemical carrier are placed on the moulding bed of building berth;
B, the air bag of a plurality of unaerateds laterally is placed in the middle of the moulding bed equably, lays by the horizontal rib backguy of the hull of inland river chemical carrier when air bag is installed, air bag quantity is 20-30;
0.4Kg gas fills in C, elder generation in air bag, control pressure in the air bag by observing compression indicator, and, begin inflation from the last air bag of hull during airbag aeration with the air bag after the tight inflation of steel rope strand, intact when whole airbag aerations, hull rises and begins to take out from bottom to top moulding bed after one's death;
After D, all moulding beds cleaned out hull, the air bag that is positioned at the hull anterior locations was exitted successively, made hull reduce the gradient;
E, control the pressure of all air bags, control hull bottom and ground-surface height, keep hull not stranded with this by the observed pressure table;
F, bow is connected with winch, stern is connected with tugboat, and tugboat drags hull, and winch holds hull by steel rope, makes hull slowly descend water;
After G, hull descended water fully, air bag all emerged, and regained all air bags.
The present invention compared with prior art has the following advantages: the weight of air bag is little, be beneficial to and move and install, the sliding friction coefficient is little, and air bag can carry out repeated usage, and can carry out pressure in the air bag according to the weight of different maritime works's products and oad, as the quantity of air bag and position etc., air bag launching scheme cost is low, and risk is little, and is easy to make, operating cost reduces relatively, the safety factor height.
The specific embodiment:
In order to deepen the understanding of the present invention, the invention will be further described below in conjunction with embodiment, and this embodiment only is used to explain the present invention, do not constitute the qualification to protection domain of the present invention.
The present invention may further comprise the steps by a kind of specific embodiment of air bag with the launched method of inland river chemical:
A, cleaning are used for placing the foreign material on the building berth of inland river chemical carrier, the inland river chemical carrier are placed on the moulding bed of building berth;
B, the air bag of a plurality of unaerateds laterally is placed in the middle of the moulding bed equably, lays by the horizontal rib backguy of the hull of inland river chemical carrier when air bag is installed, air bag quantity is 20-30, guarantees launched straightness accuracy;
0.4Kg gas fills in C, elder generation in air bag, control pressure in the air bag by observing compression indicator, and, begin inflation from the last air bag of hull during airbag aeration with the air bag after the tight inflation of steel rope strand, intact when whole airbag aerations, hull rises and begins to take out from bottom to top moulding bed after one's death;
After D, all moulding beds cleaned out hull, the air bag that is positioned at the hull anterior locations was exitted successively, made hull reduce the gradient, prevented that hull from pouring in the water fast;
E, control the pressure of all air bags, control hull bottom and ground-surface height, keep hull not stranded with this by the observed pressure table;
F, bow are connected with winch, and stern is connected with tugboat, and tugboat drags hull, and winch holds hull by steel rope, prevent that the following water speed of hull is very fast, make hull slowly descend water, avoid down water danger;
After G, hull descended water fully, air bag all emerged, and regained all air bags, so that recycling.
This launching method cost is low, and risk is little, the safety factor height, and also air bag can repeated usage, and operating cost has reduced relatively.
