Abstract
The utility model discloses a ship end launching auxiliary device in a dry season, which comprises two sets of combination devices. The two sets of combination devices are symmetrically arranged on two sides of the tail of a ship (4), each set of combination device comprises an air sac (1), a fixing grillage (2) and a connecting truss (3), the upper portion and a side surface of each connecting truss (3) are connected with the tail of the ship (4), the fixing grillage (2) is disposed on the other side of the corresponding connecting truss (3), a cavity is arranged on each fixing grillage (2), and each air sac (1) is located in the corresponding cavity. The ship end launching auxiliary device in a dry season not only can effectively avoid tail drop accidents when in end launching of the ship, realizes safe ship launching in the dry season, further reduces cost due to other newly-built launching facility, and increases economic benefits of enterprises.
Description
Technical field
The utility model relates to a kind of boats and ships end launching in low water season auxiliary device.
Background technology
Because seasonal variation takes place in water level of yangtze river, add the influence of composite factors such as alluvial, the terminal water level of dry season slideway is lower, the tail accident that falls very easily takes place during boats and ships end launching, it is a kind of extremely dangerous accident that tail falls, in boats and ships end launching process, do not allow to occur, this can cause, and boats and ships can't normally descend water between low water season, way end will have a very big counter-force to act on bottom of ship to make the bottom damage water inlet when tail taking place falling accident, even can make lives and properties suffer heavy losses.Normally descending the time of water at some shipbuilding enterprise boats and ships of the Changjiang river middle and upper reaches area is that annual May is to September, it only is 5 months, and the time that can satisfy the requirement of ton launching water level only has 2 months, boats and ships can not normally descend water, the shipbuilding period that has a strong impact on, the a large amount of segmentations that cause are overstock in the stockyard, have occupied the shipbuilding place.When normal water down, the plenty of time is used for water under the lift-launch of segmentation, and the duration is tighter, and this has seriously hindered the development of shipyard.For fear of this stubborn problem, some descends water by other modes in these boats and ships enterprises, as digs the deep water dock or build the floating drydock and descend water, and still the facility of newly-built these two kinds of following water is all up to hundred million yuan, centering craft enterprise, this will be a white elephant.
Summary of the invention
The utility model provides a kind of boats and ships end launching in low water season auxiliary device, the tail generation of accident that falls when it not only can avoid boats and ships end launching effectively, water under the safety of realization boats and ships in low water season, and reduced newly-built other and descended the cost of water mode facilities, increased economic benefit of enterprises.
The utility model has adopted following technical scheme: a kind of auxiliary device of boats and ships end launching in low water season, it comprises two groups of composite sets, two groups of composite sets are symmetricly set on the both sides of boats and ships afterbody, every group of composite set comprises air bag, fixing frame plate and is connected truss, the top that connects truss is connected with the afterbody of boats and ships with a side, be provided with fixing frame plate at the opposite side that connects truss, fixing frame plate is provided with cavity, and air bag is positioned at cavity.
Described fixing frame plate is that steel plate is welded.Described connection truss is welded by steel pipe, and the cross section that connects truss top is a triangle, and the cross section of bottom is a square.
The utlity model has following beneficial effect: the utility model is provided with air bag, air bag can improve buoyancy and moment of buoyancy, when boats and ships end launching enters subordinate phase, when center of gravity skids off way end, make buoyancy to the moment of way end greater than the moment of gravity to way end, avoid down the fall generation of accident of water boats and ships tail, guarantee simultaneously when gravity equals buoyancy to the moment of front frame to the moment of front frame, it is floating that following water boats and ships begin tail, and the safety of raising launching in low water season, it is in good order to guarantee that boats and ships enterprise produces, smoothly deliver the vessel, reduce simultaneously the cost of newly-built other following water mode facilities again, increased economic benefit of enterprises.Connection truss and fixing frame plate that the utility model is provided with can be guaranteed the intensity of structure under the synergy of the impulsive force of water and buoyancy like this.

The specific embodiment
At Fig. 1, among Fig. 2 and Fig. 3, the utility model is a kind of auxiliary device of boats and ships end launching in low water season, it comprises two groups of composite sets, two groups of composite sets are symmetricly set on the both sides of boats and ships 4 afterbodys, every group of composite set comprises air bag 1, fixing frame plate 2 be connected truss 3, fixing frame plate 2 is welded for steel plate, the top that connects truss 3 is connected with the afterbody of a side with boats and ships 4, be provided with fixing frame plate 2 at the opposite side that connects truss 3, fixing frame plate 2 is provided with cavity, and air bag 1 is positioned at cavity, connects truss 3 and is welded by steel pipe, the cross section that connects truss 3 tops is a triangle, and the cross section of bottom is a square.The utility model discloses a kind of method for making of boats and ships end launching in low water season accessory appliances, it may further comprise the steps: step 1, size according to Ship Statics groundwork design air bag 1, air bag 1 is used to improve buoyancy and moment of buoyancy, length and diameter by design air bag 1, when boats and ships end launching enters subordinate phase, when center of gravity skids off way end, make buoyancy to the moment of way end greater than the moment of gravity to way end, guarantee that simultaneously it is floating that following water boats and ships begin tail when gravity equals buoyancy to the moment of front frame to the moment of front frame; Fixing frame plate be connected truss; Step 2, according to structural mechanics of the ship groundwork designs fix grillage 2 and the size that is connected truss 3, fixing frame plate 2 is welded for steel plate, connecting truss 3 is welded by steel pipe, the cross section that connects truss 3 tops is a triangle, the cross section of bottom is a square, air bag 1 is fixed in the cavity of fixing frame plate 2, connect truss 3 and be used to be connected and fixed grillage 2 and boats and ships 4, when air bag 1 during with certain initial velocity entry, to be subjected to the impact force action of very big water, be subjected to the buoyancy of water effect simultaneously again; By finite element software designs fix grillage 2 and the size that is connected truss 3, guarantee the intensity of auxiliary mould structure under the synergy of the impulsive force of water and buoyancy.
