Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention; based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in figure 1, the special jig frame for the floating roof extraction support of the large-scale oil tank comprises a plurality of floating roof supports C arranged on a tank bottom plate E, wherein floating roofs B are arranged on the tops of the floating roof supports C, and door-shaped jig frames A capable of walking along the tops of the floating roof supports B are arranged on the floating roofs B.

As shown in fig. 2-4, the door-shaped jig frame a includes a lower half column and a support 1 respectively disposed at two sides, universal wheels 7 are installed at the bottom of the lower half column and the support 1, a horizontal pull support 6 is connected between the lower half column and the support 1 at two sides, the top of the lower half column and the support 1 is fixed with an upper half column 3 through a threaded screw rod 2, a horizontal support beam 4 is connected between the upper half column 3 at two sides, and an electric hoist 8 is disposed in the middle of the horizontal support beam 4.

The lower half part upright post and the support 1 comprise base channel steel 1-1, the upper part of the base channel steel 1-1 is fixed with a lower half part steel pipe upright post 1-2, a base inclined strut 1-3 is arranged between the lower half part steel pipe upright post 1-2 and the base channel steel 1-1, and the middle part of the lower half part steel pipe upright post 1-2 is fixed with a horizontal support connecting plate 1-4 for installing a horizontal pull support 6.

The horizontal support beam 4 comprises a horizontal beam steel pipe 4-1, steel pipes 4-3 which can be inserted into the upright columns 3 on the upper half part are welded at two ends of the horizontal beam steel pipe 4-1, and two groups of inclined support connecting plates II4-2 are arranged at the bottom of the horizontal beam steel pipe 4-1; the upper half upright post 3 comprises a steel pipe upright post 3-1, an inclined strut connecting plate I3-2 is welded on the inner side of the steel pipe upright post 3-1, and an inclined strut 5 is connected between the inclined strut connecting plate I3-2 and the inclined strut connecting plate II 4-2.

As shown in figure 5, a screw hole is formed in a base channel steel 1-1, a screw rod 1-5 penetrates through the screw hole, and a supporting block 1-6 is arranged at the lower end of the screw rod 1-5. The door-shaped jig frame is used for being installed on the floating roof B, the fixing effect of the common brake universal wheel 7 is weak, and the support blocks 1-6 at the lower ends of the screws 1-5 and the brake universal wheel 7 jointly play a supporting and fixing effect through the arrangement of the screws 1-5 capable of being adjusted up and down.

The utility model discloses a concrete method for construction as follows:

s100, lofting each node of the portal jig frame A by using CAD according to the height of the support column, blanking lofted dimension data by using a cutting machine, and carrying out component assembly and welding in a prefabrication yard.

S200, assembling and assembling each component while welding the components in a prefabricated yard in a group, so that each component can be smoothly installed on site, and during preassembly, in order to save time, preassembly of each component is carried out in a bolt manner. Because drawing pillar size height is inconsistent, plays to rise when taking out the pillar highly inconsistent, and the bed-jig stand need install the regulation lead screw additional and adjust the bed-jig stand height, for easy to operate at the bed-jig stand 1.2 meters welding the lead screw, guaranteed that the bed-jig height can be adjusted at any time.

S300, transporting each prefabricated part to the site, transferring the prefabricated part into a storage tank floating roof by using a crane, formally assembling each small part, formally fixing and assembling after checking and correcting errors, and fixing by using bolts during assembly. The door style of calligraphy bed-jig self dead weight is about 100Kg, and it takes time and labours to have taken out to lift the support by the manpower for every pillar, has installed the brake universal wheel on the bed-jig supports the channel-section steel through field study, as long as two people just can easily pass the bed-jig and construct, pulls down the brake of brake universal wheel when the bed-jig shifts to the construction position in order to guarantee the stability when taking out the pillar.

S400, conducting power-on debugging on the lifting device of the assembled door-shaped jig frame, debugging the height of the door-shaped jig frame after proper debugging to enable the height of the door-shaped jig frame to reach the height when the upright post is pulled out, ensuring the level of the door-shaped jig frame during adjustment, and pulling out the floating roof support post after the adjustment is completed. Because the common fixed pulley adopted in the previous construction lifts the pillar, an operator needs to do strenuous operation, and finally, a 0.5-ton electric hoist is arranged on the I-shaped steel of the portal beam of the jig frame, and the pillar can be drawn out as long as the operator hangs the lifting button of the lifting hook to lift.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
