Description
Technical field
The utility model belongs to a kind of petrol storage tank, is specifically related to a kind of novel group of 150,000 vertical petrol storage tanks that jig is connected.
Background technology
China builds large-scale storage tank and starts from 1986, because many factors can body material was once once depending on the SPV490 high tensile steel plate that nippon and JFE provide.Over more than 20 year, the economic develop rapidly of China, energy strategy plan has obtained abundant attention and the support of country, and more than 300 100,000 m3 tanks have been built in successively investment, and the units such as design, manufacture, construction participate in many ways, solidarity and cooperation make large-scale storage tank construction comprehensive strength obtain fast lifting.Large-scale storage tank is the difficult point during storage tank is built with design, manufacture, the construction of high strength steel plate always, wherein the highest with the technical requirements of bottom ring wall plate again, because this position stressing conditions of storage tank is the most complicated, is the relative thin weakness that causes tank body to destroy.For guarantee storage tank be constructed and put into operation after safe operation, the high strength of petrol storage tank work, high tenacity, good welding performance, four subject matters that are applicable to Large Heat Input Welding must draw attention.
The stressed static pressure that is mainly derived from storage medium of storage tank shell.Hydrostatic column pressure increases distribution triangular in shape from top to bottom gradually, and at when design wallboard progressive additive from top to bottom, thickness and width increase due to 150,000 m3 storage tank bottom ring wall plates, caused certain difficulty to construction.Individual bottom ring wall plate weight reaches 12t, during installation, require whole circle levelness to be no more than 6mm, longitudinal joint group is 4～5mm to clearance control, that construction technology or Lifting Capacity are all higher than 100,000 m3 storage tank requirements, 150000 m3 storage tank foundation ring perforated wall plates are because thickness of slab increases welding capacity than 100,000 m3 storage tanks many 1/4th, simultaneously in conjunction with production operation condition of service, heat treatment technics condition has been made to necessary adjustment, 150000 m3 storage tank bottom ring wall plate thickness have reached 40mm, single-sided welding fusion penetration is 23mm left and right, multiple welding test figures proof single-sided welding one-shot forming technique thickness of slab should be less than 25mm, otherwise joint dynamic ductility is poor, heat affected zone absorbed-in-fracture energy reduces very fast, conventionally only has 20J left and right.In order to meet weld heat input, be not more than the technical requirements of 100kJ/cm, during installation, group is very harsh to quality, group to gap by 100,000 m3 storage tank longitudinal joint groups to gap 4～6mm, be adjusted into 4～5mm, by the minimizing of loading, control the object that time that wire feed stops reaches control line energy.But group should not be less than 4mm to gap, otherwise easily form narrow and dark groove, wire feed is difficult to put in place and causes occurring dead angle, will produce the defects such as lack of penetration, slag inclusion after welding.Particularly important to methods such as size, transformation tooling fixture, Optimizing construction programs by accurate Calculation group during construction, the transformation outbalance of heat treatment mold must be considered the distortion and the displacement problem that in transportation, handling and heat treatment process, occur, but for the problem of the existence of above construction technology at present all less than not only economical and practical but also succinct failure-free treatment measures.

As shown in Figure 1, a kind of novel group of 150,000 vertical petrol storage tanks that jig is connected, it is characterized in that: comprise tank bottom 3, first lap tank shell 4, back of the body thick stick 5, tank deck 9 floats, gantry clamp 12, described first lap tank shell 4 lower edges are with back of the body thick stick 5, the first back of the body thick stick 5 is fixed on first lap wallboard 4 by gantry clamp 12, first lap wallboard 4 top angles connect and weld, the second circle wallboard 13 is placed on the outside of first lap wallboard 4, described first lap wallboard 4 is connected jig with the circumferential weld group of passing through of the second circle wallboard 13, the second back of the body thick stick 5 is fixed on the second circle wallboard 13 by gantry clamp 12, each encloses peripheral wallboard and is arranged on by the way successively outside the second circle wallboard 13, between described tank bottom 3 each layers, with above-mentioned same way, by vertical seam group, jig is connected adjusting screw with group, on described tank bottom 3, fix a lift columns 2, described lift columns 2 both sides, top are symmetrically arranged with two the first hangers 8, center position at tank bottom 3 arranges lift columns 2, between one side of described lift columns 2 and tank bottom 3, be connected with cable-stayed support 1, on described back of the body thick stick 5, be provided with the second hanger 6, described the second hanger 6 is connected with the first hanger 8 by jack bont 7, described lift columns 2 is provided with capital cover plate 10, described unsteady tank deck 9 covers respectively enclosing on tank shell of being installed together, in described tank body, being provided with liquid level detects and telltale 11, described tank wall has oil outlet 14, described tank body oil inlet 15 is opened on the tank bottom 3 of tank body, described oil outlet 14, oil inlet 15 front ends are provided with oil-flow control apparatus 16.
In the present embodiment, described vertical seam group to jig and square, square cotter, the sub-cooperation of round pin to be connected tank bottom 3 each layer of steel plate.
In the present embodiment, described circumferential weld group coordinates be connected first lap wallboard 4, the second circle wallboard 13 and respectively enclose peripheral wallboard to jig and square, square cotter.
In the present embodiment, described wallboard group is circular nut to adjusting screw matching nut.
In the present embodiment, described base plate group is square nut to adjusting screw matching nut.
In the present embodiment, it is thickness 16mm, Q235-A steel plate that described vertical seam group is all selected specification and material to jig, gantry clamp 12.
In the present embodiment, it is thickness 32mm, Q235-A steel plate that described square, square cotter are selected specification and material.
In the present embodiment, it is diameter 80mm, Q235-A round steel that described leading screw is selected specification and material, and screw thread is buttress thread.
In the present embodiment, it is diameter 32mm, Q235-A round steel that described round pin is selected specification and material.
