Description
Technical Field
The invention relates to the technical field of ship construction, in particular to a method for positioning a stern ramp rubber groove bracket of a stern ramp of a large ship.
Background
The stern passage system of large ship consists of stern door and stern springboard, is used for the large hovercraft to enter and exit from the dock cabin, and is the key of the whole passage system. The stern springboard is fixed at the dock cabin deck through a hinge, the stern door is hung upside down on the stern sealing plate through the hinge, and when the stern door and the stern springboard are closed together, the stern door and the stern springboard are locked into a whole through the hydraulic bolt and pressed on the rubber positioned on the door frame, so that the stern part of the ship is closed, the outer side of the ship body and the dock cabin are effectively separated, and the watertight bulkhead is played. The stern door and the stern ramp are complex in design, so that the installation is very complicated, the invention patent with the application number of 200810041802.1 discloses an installation method of a stern door transmission system of a large ship, the installation of the stern door transmission system can be referred to the patent, and the installation of a stern ramp rubber groove bracket at the bottom of the stern ramp is more important.
Rubber grooves are arranged around the stern sealing plate door frame along the contour of the stern sealing plate door frame, and rubber is arranged in the rubber grooves. The rubber groove at the bottom of the stern springboard can not be directly arranged on the doorframe of the stern springboard due to the reason that the bottom of the springboard is provided with the hinge, and the rubber groove needs to be extended outwards by means of a bracket of the stern springboard rubber groove. Because the structural dimensions of the stern transom and the stern transom of each ship have certain errors, and the transverse width of the stern transom door frame is about 20 meters, certain deformation exists in the span range, and the factors can cause the gap between the stern transom and the stern transom door frame at the rubber groove to be inconsistent, so that the compression amount of rubber in the sealing groove is inconsistent, the tightness of a stern channel is influenced, and the phenomenon of water leakage caused by untight sealing in the future use process is easily caused.
Disclosure of Invention
In order to solve the technical problem, the invention provides a method for positioning a rubber trough bracket of a stern ramp of a large ship, which is realized by the following technical scheme;
a method for positioning a stern ramp rubber groove bracket of a stern ramp of a large ship comprises the following steps:
step 1, preassembling a stern door and a stern springboard to an installation position;
and 5, installing rubber in the rubber groove of the stern springboard.
Further, in step 1, the stern door and the stern ramp are temporarily fixed according to the up-down, left-right positions of the stern door and the stern ramp relative to the frame of the stern seal plate and the compression amount of the rubber.
Furthermore, the positioning model of the stern springboard rubber groove bracket is a plate with the same cross section size and shape as the cross section of the stern springboard rubber groove bracket, and the stern springboard rubber groove bracket is temporarily replaced by the positioning model of the stern springboard rubber groove bracket, so that the position of the scribed positioning reference line of the stern springboard rubber groove bracket can be ensured to be more accurate.
Further, in the step 2, the stern ramp rubber groove bracket model is vertically attached to a stern seal plate bottom door frame and a stern ramp at the same time, lines are drawn along the lower end of the attachment of the stern ramp rubber groove bracket model and the stern seal plate bottom door frame, lines are drawn along the stern seal plate bottom door frame at intervals of 0.5-1m in the transverse direction, and then the drawn lines are sequentially connected through straight lines to obtain a stern ramp rubber groove bracket positioning datum line.
Further, in step 3, the transom is opened, and the transom rubber groove bracket is installed along the positioning datum line of the transom rubber groove bracket.
Further, before the rubber is installed in the rubber groove of the stern ramp, the rubber groove of the stern ramp and the bracket of the rubber groove of the stern ramp are polished and coated, and then the rubber is installed in the rubber groove of the stern ramp.
The invention has the beneficial effects that:
1. the method can ensure the installation size of the rubber groove bracket of the stern ramp, improve the installation precision of the stern door and the stern ramp, avoid the influence on the sealing performance of a dock cabin due to the installation deviation of the rubber groove bracket of the stern ramp, and shorten the installation period of a channel system while ensuring the installation quality of a ship channel system from the source.
2. The method can also quickly position the installation position of the rubber groove, and is convenient for field construction, thereby reducing the labor intensity of workers, improving the operation efficiency, further shortening the installation period of the channel system, and creating favorable conditions for shortening the ship construction period.
3. The requirement on the labor skill of workers is not high, the labor intensity of the workers can be reduced, and the effect of knowing and releasing the production force is achieved.
