Description
Technical Field
The utility model relates to the technical field of storage tank floating roofs, in particular to a novel height-adjustable support leg for an inner floating roof storage tank.
Background
The inner floating roof storage tank is an oil tank with a floating roof arranged above the liquid level in the vault oil tank, and the loss of light oil stored in the inner floating roof storage tank can be reduced by 95-97 percent compared with the vault tank. For the internal floating roof storage tank, the floating disc in the oil storage tank is a floating roof floating on the liquid level of the oil tank and ascending and descending along with the oil, so that the volatilization loss of the medium can be reduced, the medium is effectively isolated from the stored material and the air in the tank, the danger level of fire explosion is reduced to a certain extent, the vault outside the oil storage tank can prevent rainwater, snow, dust and the like from entering the tank, and the cleanness of the medium in the tank is ensured.
However, with the gradual development of the storage tank technology, for the inner floating roof storage tank, no matter the open bay type inner floating roof or the single-disc type inner floating roof, the double-disc type inner floating roof and the floating-cylinder type inner floating roof are good, the structure, the material and the accessories of the floating disc are innovated along with the development of the technology, for example, the development of new technologies such as a large amount of application of a novel composite floating disc and full compensation efficient sealing, but the technical development of the supporting legs of the inner floating roof floating disc is not taken into consideration, and the new technical innovation is provided.
Therefore, it is necessary to develop a new type of leg with adjustable height which can meet the operation and maintenance requirements of the inner floating roof tank.
In the application of the existing strut to the inner floating roof storage tank, GB 50341-2014 has a definite technical specification for the inner attached roof strut: the inner floating roof should be provided with fixed or adjustable floating roof struts. When the inner floating roof is at the lowest supporting height, the floating roof and accessories below the floating roof cannot collide with each other; the struts should not collide with the fixed roof when the floating roof is at the maximum design liquid level. When no drainage device or other measures for preventing the accumulation of stored liquid are arranged on the inner floating roof, the inner floating roof strut can support the self weight of the floating roof and uniformly distribute additional load of 0.6 kPa. The upper end of the pillar is sealed and the lower end is blind or provided with a liquid outlet. A base plate with the thickness not less than 5mm and the diameter not less than 500mm is arranged at the position of the tank bottom plate contacted with the support, and a continuous fillet weld is adopted between the periphery of the base plate and the tank bottom plate.
The floating plate of the inner floating roof oil tank is supported by a plurality of supporting columns when falling to the bottom of the tank. The supporting height is two: one is the lowest position of the float and the other is the float height at the time of servicing.
The existing supporting legs generally have two modes, one mode is that the supporting legs are fixed at the bottom of a tank and have fixed height and cannot be adjusted; the other type can be lifted along with the floating plate, and the height of the supporting leg can be adjusted. The existing support has the disadvantage that the support is 1000m3An internal floating roof tank, 1000m3The design height of the inner floating roof storage tank is 12.69m, the designed highest liquid level of the inner floating roof storage tank is 80% of the height of the tank body, namely 10.152m, in order to facilitate the future inspection and maintenance of the storage tank, the fixed height of the supporting legs of the conventional floating plate is 1.8m, namely the effective height of the floating plate in operation is only 8.352m and 1000m3The actual storage amount of (8.352/12.69) × 1000m3＝658m3The actual utilization rate of the storage tank is only 65.8 percent. If the supporting legs are adjustable, the actual utilization rate of the storage tank can be increased.
The storage tank can involve the anticorrosive of jar wall examining the maintenance in-process, but at anticorrosive in-process, always can have the dead angle, sealed and jar wall laminating position behind the floating plate bottoming promptly, need to carry out anticorrosive just can only demolish current sealing device to the whole jar wall, resumes sealed again after anticorrosive work is accomplished. The service life of the conventional bag type seal is about 8 years, and the fully-compensated efficient seal is up to 20 years. There are a number of operational risks during the removal process and the sealing device is very vulnerable. Therefore, the anticorrosion work can be only abandoned if not necessary, and if the floating plate can freely lift in the anticorrosion process, the anticorrosion operation can be carried out on the wall of the whole tank, so that the use safety and the service life of the storage tank are improved.
Also at 1000m3For example, an internal floating roof tank has the following working modes: after the floating disc falls to the ground, water is filled in the tank, the supporting legs are adjusted after the floating disc rises along with the liquid level and are fixed by the bolts, and after the supporting legs are completely adjusted, water is discharged to enable the floating disc to fall to the ground, so that the purpose of adjusting the supporting legs is achieved. Although the adjusting mode of the supporting leg can realize the adjustment of the supporting leg according to the construction requirement on site, the method has the following great disadvantages: first, charge and dischargeWater requires a large amount of time and cost, and the construction period is increased; second, economic cost, assuming the adjustable legs are to raise the floating plate to 2.4m height, then (2.4/12.69) × 1000m is needed3＝189m3Water, the price of water is according to 8 yuan/m3I.e. 1512 yuan of water is needed for adjusting the supporting legs of the floating plate once, and the economic cost is increased.
Therefore, in summary, the existing inner floating roof floating plate supporting legs have certain problems to be solved urgently.

The novel height-adjustable support leg for the internal floating roof storage tank is characterized in that the T-shaped lead screw (2) is fixed and does not rotate, the nut rotates to drive the support leg inner tube (9) and the bearing seat (13) to synchronously rotate, the T-shaped lead screw (2) moves up and down, the cap seat (15) synchronously rises and falls along with the bearing seat (13), the bearing seat (13) is connected with the cap seat (15) through a thrust bearing (14) and rotates relatively, and the cap seat (15) is kept stationary.
6. The novel height-adjustable leg for the internal floating roof tank is characterized in that the pitch between the pin insertion holes (91) is set to be integral multiple of the thread of the T-shaped lead screw (2), and after the T-shaped lead screw (2) rotates an integral number of turns, the pin insertion holes (91) correspond to the pin limiting through holes (10); the pin limiting through hole (10) is transversely formed into an oval long hole, and the pin inserting hole (91) is formed into a round hole.
