[0002] The floating roof of a double-dish floating roof tank is composed of a bottom plate, baffles, trusses, top plate, supports, vent valves, emergency drainage devices, etc., and mainly serves to reduce oil evaporation and seal. In particular, the structure of large double-dish floating roof tanks is complex. A single 100,000 cubic meter tank floating roof weighs 565 tons and has a diameter of 80 meters. The construction period is long and the amount of welding work is large. Moreover, the assembly of the floating roof must be carried out on a special support jig. In view of the characteristics of the floating roof, this invention develops a floating roof support jig and adjustment device that can be quickly assembled, disassembled and adjusted, so as to save construction time and improve construction efficiency.

[0003] Steel floating roofs have installation height requirements when fabricated and installed on-site. They need to be fabricated at a specific height above the bottom plate of the storage tank. Therefore, a jig is needed to support the floating roof. Currently, the main types of floating roof jigs are full-span steel supports, threaded adjustment jigs, and welded jigs. Fabrication on-site inside the storage tank has disadvantages such as complex manufacturing process and slow adjustment speed. Summary of the Invention

The length of the lever arm is not less than 1.8 meters. The fixing ring is welded to the surface of the vertical tube. Each fixing ring has three side plates welded at equal intervals on its sides. The length of the side plates is not less than 15 centimeters.

[0015] Compared with the prior art, the present invention provides a steel floating roof support jig and adjustment device, which has the following advantages:

[0016] 1. The steel floating roof support jig and adjustment device, outer rod, inner rod, top plate, locking device, and diagonal bracing device are all designed as separate structures before being assembled into a single support unit. During assembly, the inner rod is first inserted from the bottom of the outer rod, and then a circular limiting plate is welded to the bottom of the inner rod. Next, the top plate is welded to the top of the inner rod. Then, an adjustment hole is selected on the inner rod as the initial position, and the locking device is inserted into the inner rod. Subsequently, the outer rod is inserted into the ground insertion rod and welded to the welding plate, thus completing the assembly of a single support unit. The support unit is then moved from the center of the storage tank outwards along a 90° angle from the center of the storage tank. 270° direction and 90° The support jigs are arranged in a 270° parallel line, and then connected in an equilateral triangle by connecting beams and connecting pins. This completes the construction of the entire support jig. Compared with traditional support jigs, the construction process not only greatly reduces the welding steps, but also simplifies the overall structure and effectively improves the efficiency of jig manufacturing.

[0017] 2. The steel floating roof support fixture and adjustment device, when adjusting the height, place the triangular base frame next to the support unit, then select a suitable side plate on the vertical pipe and place the selected side plate under the top plate. Then, insert the bottom end of the vertical pipe into the connecting rod. The worker then holds the other end of the lever arm and presses down to lift the vertical pipe, thereby moving the inner rod upward. After adjusting the height, pull out the locking device, and then insert the locking device into the adjustment hole closest to the top of the outer rod. This releases the pressure on the lever arm, completing the height adjustment of the support fixture. If you want to lower it, simply lift the inner rod using the lever arm beforehand, then pull out the locking device, and then slowly lower the inner rod. After the inner rod descends to the appropriate height, insert the locking device back into the inner rod. The entire height adjustment process is simple and quick. Compared with traditional support fixtures, it can achieve the purpose of rapid height adjustment, thereby ultimately saving construction time and improving construction efficiency.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-4 A steel floating roof support fixture includes an outer rod 1a disposed on a mounting surface 1, and an inner rod 3a is slidably installed inside the outer rod 1a.

[0028] The inner diameter of the outer rod 1a is 0.2-0.3 cm larger than that of the inner rod 3a, which facilitates the sliding of the inner rod 3a up and down inside the outer rod 1a.

[0029] A circular limiting plate extending to the side wall of the outer rod 1a is fixedly installed at the bottom of the inner rod 3a. A height limiting groove adapted to the limiting plate is provided on the side wall of the outer rod 1a. The height of the height limiting groove is five-sevenths of the height of the outer rod 1a. The height limiting groove extends downward to the bottom of the outer rod 1a.

[0030] When installing the inner rod 3a, insert the inner rod 3a into the bottom of the outer rod 1a, and then weld the circular limiting plate to the bottom of the inner rod 3a.

[0031] A circular welding plate 2a is welded to the bottom of the outer rod 1a. The diameter of the welding plate 2a is larger than that of the outer rod 1a. The welding plate 2a is welded to the mounting surface 1. A ground insertion rod 21 extending into the outer rod 1a is fixedly installed at the center of the top of the welding plate 2a. The diameter of the ground insertion rod 21 is equal to that of the circular limiting plate.

[0032] The stability of the installation of the outer rod 1a is strengthened by welding the plate 2a and the ground plug rod 21.

[0033] Please refer to Figure 2-3 , on the surface of the inner rod 3a, a number of "convex" - shaped adjustment holes 4a are evenly arranged at equal intervals. The number of adjustment holes 4a is distributed along a vertical line. And on the surface of the inner rod 3a, a clamping device 7a in contact with the outer rod 1a is provided, and the clamping device 7a is inserted into the adjustment hole 4a.

[0034] The clamping device 7a includes a clamping rod 71a slidably installed on the side wall of the inner rod 3a. At the bottom of the clamping rod 71a and inside the inner rod 3a, a limiting block 72a is fixedly installed. And at one end of the clamping rod 71a away from the limiting block 72a, a sheath 73a made of rubber is fixedly installed, and anti - slip lines are provided on the surface of the sheath 73a.

[0035] Among them, the height of the adjustment hole 4a is greater than the height of the clamping device 7a. And the adjustment hole 4a is composed of a vertical groove and a horizontal groove. The width of the vertical groove is 0.2 - 0.4 cm larger than the thickness of the clamping rod 71a, which is convenient for the clamping rod 71a to be inserted. The width of the horizontal groove is more than 1 cm larger than the width of the vertical groove. The limiting block 72a is "convex" - shaped, and the width of the limiting block 72a is greater than the width of the vertical groove and less than the width of the horizontal groove.

[0036] When the clamping device 7a is inserted, under the action of gravity, the inner rod 3a drops downward and presses on the clamping rod 71a, so that the inner rod 3a stays at the corresponding height. And due to the limitation of the limiting block 72a, the clamping device 7a will not fall automatically, thus ensuring the stability of the inner rod 3a.

[0037] On the surface of the outer rod 1a, a diagonal brace device 8a fixedly connected to the installation surface 1 is provided to enhance the stability of the outer rod 1a after installation.

At the side of the sleeve 81a, three diagonal brace arms 82a are evenly and fixedly installed at equal intervals. At the bottom of the diagonal brace arm 82a, a grounding plate 83a is fixedly installed.

[0039] And on the surface of the outer rod 1a, a limiting collar 9a adapted to the sleeve 81a is fixedly installed, and the position of the sleeve 81a is determined by the limiting collar 9a.

[0040] Among them, the diagonal brace arm 82a forms an angle of 40 degrees with the horizontal plane. The grounding plate 83a is welded to the installation surface 1. The sleeve 81a is located at the bottom of the limiting collar 9a, and the sleeve 81a is welded to the outer rod 1a. The included angle between two adjacent diagonal brace arms 82a is 60 degrees.

A top insertion rod 51a extending into the inner rod 3a is fixedly installed at the center of the bottom wall of the top plate 5a to enhance the stability of the top plate 5a. The diameter of the top insertion rod 51a is 0.2-0.3 cm smaller than the inner diameter of the inner rod 3a to facilitate the insertion of the top insertion rod 51a.

[0042] A top seat 52a is fixedly installed at the center of the top wall of the top plate 5a. At the same time, six connecting holes 53a are evenly spaced on the surface of the top plate 5a and are distributed in a ring around the top seat 52a.

[0043] Among them, the top of the top plate 5a is movably installed with a connecting beam 10a through a connecting pin 6a. The connecting beam 10a is a C-shaped steel material. The surfaces at both ends of the connecting beam 10a are provided with mounting holes that are adapted to the connecting pin 6a. The connecting pin 6a passes through the connecting hole 53a. Each top plate 5a is movably connected to 6 connecting beams 10a through the connecting pin 6a.

[0044] Finally, the outer rod 1a, inner rod 3a, top plate 5a, locking device 7a, and diagonal bracing device 8a together form a support unit. There are several support units, spaced 2.2 meters apart. These support units extend outwards from the center of mounting surface 1 along a 190°-270° direction and a 90° angle. The supporting units are arranged in a straight line in a 270° parallel direction, and then connected to each other in an equilateral triangle shape by connecting beam 10a.
