The sheathing bracket for low temperature liquefied natural gas tank disclosed by the invention has a rotation frame, a side sway frame and a moving roller frame driven by hydraulic pressure; when the cylinder body of an outer tank body is sheathed outside an inner tank body, the rotation frame, the side sway frame and the moving roller frame can move correspondingly under the driving force of the hydraulic pressure, therefore, the axis of the outer tank cylinder and that of the inner tank body is on the same line, and the working efficiency is high, the working quality is good and the labor intensity is low.
Description
Technical field
The present invention relates to a kind of auxiliary device of making low-temperature liquefaction natural gas tank, particularly a kind of low-temperature liquefaction natural gas tank cover is shelved.
Background technique
Rock gas is a kind of energy of good combination property.The natural gas volume of equal in quality is 600 times of LNG Liquefied natural gas volume.For convenient transport and storage, rock gas be made to LNG Liquefied natural gas.
LNG Liquefied natural gas (LNG) is to adopt cryogenics, the liquified natural gas making by natural gas under certain pressure.
During by vehicle transport LNG Liquefied natural gas, be by low-temperature liquefaction natural gas tank splendid attire LNG Liquefied natural gas.Low-temperature liquefaction natural gas tank will ensure that the temperature of LNG Liquefied natural gas in tank is at subzero 162 DEG C ~ subzero 196 DEG C, and pressure is at 0.65Mpa ~ 1.59Mpa.
In order to improve conveying efficiency, reduce cost of transportation, meeting under the prerequisite of communications and transportation specification, low-temperature liquefaction natural gas tank is large as much as possible, and the length of low-temperature liquefaction natural gas tank can reach 12 meters at present, and diameter can reach 2.5 meters, and volume can reach more than 50 cubic metre.
Vehicle transport has the interior tank body and the outer tank body that are nested together with low-temperature liquefaction natural gas tank, interior tank body and outer tank body have cylindrical drum, and there is ellipsoidal head at the two ends of cylindrical shell.Gapped between interior tank body and outer tank body, the outside of interior tank body is coated with flexible aluminium foil thermal insulation quilt, the cylindrical shell inner side of outer tank body is evenly equipped with ring stiffening rib, when low-temperature liquefaction natural gas tank splendid attire LNG Liquefied natural gas, gap between interior tank body and outer tank body will be evacuated, the gap of high vacuum and aluminium foil thermal insulation quilt make LNG Liquefied natural gas in low-temperature liquefaction natural gas tank in adiabatic state, maintain LNG Liquefied natural gas in low-temperature liquefaction natural gas tank in lower temperature.
While making low-temperature liquefaction natural gas tank, first produce the cylindrical shell of interior tank body and outer tank body with steel plate, then at the coated flexible aluminium foil thermal insulation quilt in the outside of interior tank body, the ring of the inner side of tank body cylindrical shell welding outside stiffening rib, again the cylindrical shell of outer tank body is sleeved on to the outside of interior tank body from one end of interior tank body, in suit relief, between tank body and outer tank body, keep certain gap, then end socket is welded at the two ends of tank body cylindrical shell outside.
Because the length of interior tank body and outer tank body is longer, diameter is larger, tank skin is relatively thin, in when making, tank body and outer tank body cylindrical shell axially and radially has certain form and position tolerance, and when suit, outer tank body cylindrical shell has certain distortion, also there is form and position tolerance in the track of track vehicle and inner canister body axis, in order to improve the actual volume of low-temperature liquefaction natural gas tank, the gap between interior tank body and outer tank body is very little, and the inner side of outer tank body cylindrical shell is welded with ring section bar stiffening rib.In suit operation process, the axis of outer tank body cylindrical shell will keep with the axis of interior tank body on same straight line, and the gap in ensureing between tank body and outer tank body is even, and section bar stiffening rib never
Can touch the aluminium foil thermal insulation quilt of the external side flexibility of inner canister.Because above-mentioned reason, outside inner canister extracorporeal set when tank body cylindrical shell, the axis of outer tank body cylindrical shell departs from the axis of interior tank body sometimes, often need to from upper and lower to, left and right sides to axial angle on adjust the orientation of tank body cylindrical shell, avoid the stiffening rib on outer tank body cylindrical shell inner circumference to touch the coated flexible aluminium foil thermal insulation quilt of the external side of inner canister, in the operation of reality suit, it is a very difficult operation that the barrel jacket of outer tank body is contained in to the external side of inner canister.
In prior art, the barrel jacket of outer tank body is not contained in to the special purpose device of the external side of inner canister, in the time of suit operation, be by track vehicle, the assistant tool that crane etc. are general and device, track vehicle has the rectangle frame of level, there is rail wheel vehicle frame below, and there is respectively the carrier roller frame of outer tank body cylindrical shell at front portion, middle part and the rear portion above vehicle frame.When suit operation, outer tank body cylindrical shell is placed on the carrier roller frame at vehicle frame upper forepart, middle part and rear portion, track vehicle is slowly walking vertically, drive outer tank body cylindrical shell to move, from one end of interior tank body tank body cylindrical shell to be sleeved on gradually the inner canister of horizontal positioned external, when suit, should keep the axis of outer tank body cylindrical shell and the axis of interior tank body on same straight line, in the time there is deviation between the axis of outer tank body cylindrical shell and the axis of interior tank body, by the orientation of the outer tank body cylindrical shell of crane adjustment.Outer tank body cylindrical shell and the interior tank body of suit low-temperature liquefaction natural gas tank like this, inefficiency, operation quality is poor, labor intensity is large.
Summary of the invention
The object of the invention is in order to overcome above-mentioned deficiency, propose the low-temperature liquefaction natural gas tank cover that a kind of working efficiency is high, operation quality good, labor intensity is little and shelve.
The present invention is achieved using the following method.
Low-temperature liquefaction natural gas tank cover is shelved rail road car, has the rectangle frame of level in track vehicle, and there is rail wheel vehicle frame below, and vehicle frame top is connected with rotating frame, displaceable frame and mobile carrier roller frame successively,
There is the central shaft hole vertical with vehicle frame plane the centre of vehicle frame, there is the central shaft being inserted in central shaft hole centre below rotating frame, above vehicle frame, be evenly equipped with the fan-shaped slideway taking central shaft hole as the center of circle, below rotating frame, there is the fan-shaped roller group matching with the fan-shaped slideway above vehicle frame, between vehicle frame and rotating frame, be hinged with the rotating liquid cylinder pressure that can drive rotating frame to rotate around central shaft
The side direction slideway of the level that is evenly equipped with above of rotating frame, below displaceable frame, there is the parallel rollers group matching with the side direction slideway above rotating frame, between rotating frame and displaceable frame, be connected with and can drive the sidesway oil hydraulic cylinder of displaceable frame along the lateral movement of side direction slideway
