Abstract
Description
Technical Field
[0001] The utility model relates to a supporting device for a liquefied natural gas filling hose of a car roll-on / roll-off ship. Background Art
[0002] With the improvement of global environmental protection requirements, in order to control ship exhaust emissions, ships have begun to widely use clean fuels to cope with increasingly stringent emission control requirements, especially the use of liquefied natural gas (LNG) and liquefied ethane (LEG) fuels. Due to the structural characteristics of the car ro-ro ship itself, the distance from the cargo hold wall plate to the side outer plate is usually small, in order to maximize the loading of vehicles and expand the cargo hold volume. When this type of ship uses LNG or LEG as a power fuel, its LNG filling station is arranged between the cargo hold wall plate and the side outer plate. The layout of the LNG filling station is due to the large number of valves on the filling pipeline of the gas supply system, and the pipeline has low-temperature insulation. At the same time, the layout of the filling pipeline also needs to meet the internationally accepted unified requirements for the layout of the filling pipeline (usually referring to the International Gas Fuel Ship Association-SGMF) to meet the compatibility of fuel filling in the later stage, so that the layout of the LNG filling pipeline requires sufficient space. However, the small distance from the cargo hold wall plate to the side outer plate of the car ro-ro ship makes it difficult to arrange the LNG filling pipeline as a whole. The traditional hose saddle (see Chinese patent ZL202223138598.X) has a large structural size and cannot meet the layout requirements of the liquefied natural gas filling pipeline of the car roll-on / roll-off ship.

[0021] The present utility model will be further described below in conjunction with the accompanying drawings.
[0022] Please refer to Figures 1 to 8 , the support device for the natural gas filling hose of the car ro-ro ship of the present utility model includes a support frame, three hose saddles 3 and three saddle vertical adjustment mechanisms.
[0023] The support frame 1 includes four support legs 11 fixed on the hull deck 80 of the natural gas filling station, three rows of crossbars 12 connected between several support legs 11, and saddle guide grooves 2 fixed on several support legs 11. The saddle guide grooves 2 include a guide groove bottom plate 21 fixed on the four support legs 11, two guide groove side plates 22 fixed on both sides of the guide groove bottom plate 21 in a one-to-one correspondence, two guide groove end plates 23 fixed on both ends of the guide groove bottom plate 21 in a one-to-one correspondence, and a reinforcing rib 24 connected between the middle of the guide groove bottom plate 21 and the support leg 11; the bottom of each support leg 11 is welded and fixed on the hull deck of the liquefied natural gas filling station through a backing plate 10, and the backing plate 10 is made of carbon steel of the same material as the hull structure; the guide groove bottom plate 21 is provided with three pairs of perforations at intervals, and a threaded seat 210 is fixed in each perforation; the height of the guide groove end plate 23 is greater than that of the guide groove side plate 22, and the top of the guide groove end plate 23 is an arc top, and a lifting hole 230 is opened in the upper part of the guide groove end plate 23 to facilitate the lifting of the support device onto the ship after it is manufactured.
[0024] Three hose saddles 3 are installed at intervals in the saddle guide groove 2 of the support frame 1. Each hose saddle 3 includes a saddle fixing groove provided in the saddle guide groove 2 and a saddle block 4 installed in the saddle fixing groove. The saddle fixing groove includes two fixing groove side plates 31, a fixing groove bottom plate 32 connected between the lower parts of the two fixing groove side plates 31, and two hose baffles 33 connected to both ends of the fixing groove bottom plate 32 in a one-to-one correspondence. The height of the hose baffle 33 is greater than the height of the fixing groove side plate 31, and the top of the hose baffle 33 is a semi-circular arc top. The material of the saddle block 4 is made of Teflon or hardwood, and the height of the saddle block 4 is greater than the height of the fixing groove side plate 31 but less than the height of the hose baffle 33. The two sides of the top of the saddle block 4 are chamfered with arcs.
[0025] Three saddle vertical adjustment mechanisms are installed on the saddle guide groove 2 in a one-to-one correspondence with several hose saddles 3. Each saddle vertical adjustment mechanism includes two jacking screws 5 and a guiding mechanism. Among them, the two jacking screws 5 are installed from bottom to top and in a one-to-one correspondence in each pair of threaded seats 210 on the bottom surface of the guide groove bottom plate 21 and pass through the guide groove bottom plate 21. The guiding mechanism includes two vertical waist-shaped holes 220 opened at intervals on the guide groove side plate 22 and two fixing bolts 6 that are correspondingly inserted into the two vertical waist-shaped holes 220 of the two guide groove side plates 22, pass through the two mounting holes on the two fixing groove side plates 31 and the two mounting holes on the saddle block 4, and then use two nuts 60 to fix the saddle fixing groove and the saddle block 4 in the saddle guide groove.
[0026] The support device for the natural gas filling hose of the vehicle roll-on / roll-off ship of the present utility model is installed on the hull deck 80 of the liquefied natural gas filling station of the vehicle roll-on / roll-off ship. The liquefied natural gas filling station is located between the outer wall 81 of the cargo hold and the side shell plate 82. Therefore, the side of each support leg 11 is in an S shape, so that the saddle guide groove 2 installed on the top of the support leg 11 is basically in the same vertical plane as the side shell plate 82. During the filling operation, the support frame 1 bears the weight of the filling hose 7 and the cryogenic liquid inside it. By adjusting the jacking screw 5, the height position of the hose saddle 3 can be adjusted, which is especially suitable for the liquid-phase filling hose and the gas-phase filling hose with different pipe diameters in the filling station, and it is convenient to adjust the centers of the filling hoses 7 to the same height. The material of the saddle block 4 is made of Teflon or hardwood, which can prevent the cryogenic conduction of the filling hose 7 and generate static electricity due to friction with the saddle block 4. The vertical waist-shaped holes 220 opened on the guide groove side plate 22 play a guiding role when the jacking screw 5 adjusts the height of the hose saddle 3. The hose baffle 33 is used to limit the excessive deviation of the filling hose 7. The arc angles on both sides of the top of the saddle block 4 can prevent the filling hose 7 from being bent excessively and damaged.
[0027] The support device for the natural gas filling hose of the automotive ro-ro ship of the present utility model. The number of hose saddles 3 installed in the saddle guide groove 2 can be increased or decreased according to the project. When the hose saddles 3 support the gas-phase filling hose and the liquid-phase filling hose, the gas-phase filling hose and the liquid-phase filling hose can share one hose saddle 3. At this time, the length of the hose soft seat 3 should be correspondingly lengthened.
[0028] The above embodiments are only for illustrating the present utility model, rather than limiting the present utility model. Those skilled in the relevant technical fields can also make various changes or modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions should also belong to the scope of the present utility model and should be defined by each claim.
