Detailed Description
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention.
The embodiment provides a method for launching a longitudinal beef tallow slipway 5 of a ship, which comprises the following steps:
step one, building a ship on an inclined slipway, placing the ship on the stupefied wood of the slipway, sequentially arranging a left stupefied 2, a middle stupefied 1 and a right stupefied 3 along the width direction of the slipway, and arranging a sand box 4 below the left stupefied 2, the middle stupefied 1 and the right stupefied 3. The ship is built on a slipway with an inclination of 1/18 or 1/20, and the weight of the ship presses on the slipway. The structure is shown in fig. 1. The force relationship of the ship on the inclined plane is as follows:
weight Q of ship and gliding component force
Positive pressure
The reason why the ship does not slide down on the slipway is that the weight of the ship generates a sliding-down component force F smaller than the frictional resistance force F between the ship and the slipway woods. The friction force f is reduced under the action of coating grease on the slideway 5, and the ship can slide into water under the action of gravity.
Step two, coating grease on the upper surface of the slide way 5, placing the slide way 5 below the ship body, knocking the skid 7 above the sliding plate 6 to enable the sliding plate 6 to be completely contacted with the slide way 5, and transferring the ship from the slipway to the slide way 5, as shown in fig. 2. The slideways 5 are arranged into two groups and respectively positioned between the left edge 2 and the middle edge 1 and between the right edge 3 and the middle edge 1. When the paddings 7 are knocked, the lower wedge-shaped paddings 7 and the upper wedge-shaped paddings 7 are knocked at the same time on two sides of each slideway 5, and the knocking direction is from the stern of the ship to the bow of the ship. Six persons, three hammers and one person are respectively arranged inside, outside, left and right of each slideway 5, and the wood wedge is tightly pressed by force synchronously inside and outside. The tapping point is shown in fig. 3.
Step three, discharging sand in a sand box 4 below the middle ridge 1 to separate the sand box 4 from the middle ridge 1; when the sand in the sand box 4 below the middle ridge 1 is discharged, the sand is discharged from two sides of the middle ridge 1 at the same time, the port side of the middle ridge 1 is from the stern to the midship, and the starboard side of the middle ridge 1 is from the midship to the bow.
And step four, starting the sliding plate 6 booster, discharging sand in the sand box 4 below the left edge 2 and the right edge 3 after the ship is allowed to launch, separating the ship body from the support of the left edge 2 and the right edge 3, and sliding the ship body into the water from the slide way 5. The ship launching comprises four stages, namely, the ship slides to the stern to be in water contact, the stern is in water contact to the stern to float, the stern floats to the ship full float, and the ship floats to the ship full float to stop sliding. The important characteristics of stern buoyancy are: the tail end of the ship slides out of the tail end of the slide way 5 by about 1m, the bow support generates a concentrated support reaction force at the same time, and the bow support is separated from the slide way 5 after sliding on the slide way 5 for a certain distance, so that full floating is realized.
In this embodiment, the sandbox 4 comprises a supporting body 11, a baffle 12 is arranged on one side in the supporting body 11, and the baffle 12 is arranged in a downward inclination manner. One side shaft of the baffle plate 12 is connected with a locking plate 13, the other side inside the supporting body 11 is provided with a limiting plate 14, the locking plate 13 is arranged above the limiting plate 14, a sand leakage opening is formed between the baffle plate 12 and the supporting body 11, the locking plate 13 and the limiting plate 14 are used for closing or opening the sand leakage opening, and sand is stored in the upper area of the baffle plate 12. One end of the limiting plate 14 is disposed inside the supporting body 11, the other end of the limiting plate passes through the supporting body 11 and is disposed outside the supporting body 11, the other end of the limiting plate 14 is fixedly connected with a rotating shaft 15, and the rotating shaft 15 is connected with a locking mechanism for controlling the rotating shaft 15 to rotate. Locking mechanical system strikes handle 16 and support subject 11's outside axle installation including striking handle 16, locking arm 18 and spacing ring 17, strikes handle 16, and the upper end of striking handle 16 sets up in spacing ring 17, and the lower extreme of striking handle 16 is provided with locking groove 19, and the one end and the 15 fixed connection of pivot of locking arm 18, the other end lock or the unblock through locking groove 19. The use principle of the sandbox 4 in the present embodiment is as follows: strike towards the direction of supporting subject 11 during the use and strike handle 16, strike handle 16 and rotate round the pivot point, strike locking groove 19 of handle 16 bottom and outwards rotate and open, locking arm 18 breaks away from locking groove 19, locking arm 18 rotates downwards under the effect of gravity, thereby drive pivot 15 and rotate, pivot 15 rotates and drives limiting plate 14 and rotates, limiting plate 14 is opened with lockplate 13, the mouth that leaks is opened, sand spills the back height and descends, thereby stupefied 1 in the drive, stupefied 2 in a left side, the whole height of stupefied 3 in the right side descends. When the sand box 4 is disassembled, the limiting ring 17 is firstly knocked, and then the knocking handle 16, the locking arm 18 and the support main body 11 are sequentially knocked, so that sand falls down quickly.
Although the present invention has been described in detail with respect to the above embodiments, it will be understood by those skilled in the art that modifications or improvements based on the disclosure of the present invention may be made without departing from the spirit and scope of the invention, and these modifications and improvements are within the spirit and scope of the invention.
