[0023] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present application.

[0024] Embodiment 1:

[0025] The current leveling method is still to add pads at the bottom of the tire frame, but the tire frame is very heavy, and it is not only very difficult to lift the tire frame, but also requires the use of tools or equipment, and requires the cooperation of multiple people. In addition, the action of lifting the tire frame and inserting the pads at the bottom is dangerous and can easily hurt people. This leveling method with pads cannot be finely adjusted due to the thickness of the pads themselves, and can only be roughly leveled. It is difficult and time-consuming, and it brings hidden dangers to the alignment, leveling, and installation of subsequent equipment.

[0026] After our improvement, the platform system includes multiple sets of tire frame modules, each set of tire frame modules includes: a frame body, an adjustable gasket 3, a pad 9, and a flexible gasket 12;

[0027] The pad 9 is used to be laid on the ground of the site to provide a rigid support surface for the frame body and the reactor to avoid settlement and other problems that may occur due to direct contact with the ground.

[0028] The pads 9 are arranged on the site at equal intervals along the length direction of the preset reactor according to the placement area planned for the site.

[0029] The frame body is placed in the play. The overall length of the frame body is 10m*1m*1.5m (length*width*height), including a support frame 1 located on the upper layer. The support frame 1 is welded into a rectangular frame using HM400*400 steel. A support pipe 2 is welded and fixed to the support frame 1 on the bottom surface. The support pipe 2 is 6 and uses DN400*18mm steel pipes. The 6 support pipes 2 are respectively located at the corner ends (4) and the middle (2) of the support frame 1. After the overall frame is welded, the support strength is very high. Reinforcement ribs are welded between the support pipes 2 to improve the strength.

[0030] When placing on site, the top surface of the support frame 1 needs to be leveled so that the upper plane elevations of all the molds are consistent. Therefore, an adjustable gasket 3 is placed at the bottom end of the support tube 2. The adjustable gasket 3 is cross-shaped as a whole, and its bottom surface is a plane, so that it can be placed flat on the pad 9. The adjustable gasket 3 includes four wedge-shaped pads 4 that are cross-jointed. The wedge-shaped pads 4 are long strips, and one end of the four wedge-shaped pads 4 is fixedly connected to form a cross-shaped structure. The bottom surfaces of the wedge-shaped pads 4 are coplanar and flat, and the top surfaces of the wedge-shaped pads 4 are inclined surfaces 6 that rise from the inside to the outside. The outer ends of the wedge-shaped pads 4 are provided with vertical plates 5. The vertical plates 5 are provided to facilitate the adjustment of the position of the adjustable gasket 3 by tapping on the outside, and also to prevent excessive adjustment so that the outer ends of the wedge-shaped pads 4 are immersed in the support tube 2, so that the adjustable gasket 3 is always limited below the corresponding support tube 2.

[0031] Based on the above structure, when it is used, after laying the pad 9 on the site, place 6 adjustable pads 3 at the positions below the corresponding support columns. When placing the support frame 1, make sure that the bottom of the support column falls on each adjustable pad 3. Level the support frame 1 according to the level meter. Adjust the position of the adjustable pad 3 according to the data of the level meter. When adjusting, there is no need to hoist or lift the pad 9. Use a hammer to knock on the vertical plate 5 on the lower side to move it a little to the opposite side, and the height in that direction can be adjusted. Since the adjustable pad 3 has two directions and four branches distributed in a cross, it is possible to adjust the inclination in both the horizontal and vertical directions, thereby quickly and labor-savingly adjusting the inclination in two directions. This adjustment structure and method has the following two main advantages:

[0032] Firstly, there is no need to hoist or lift the support frame 1, and the adjustment can be performed labor-savingly, quickly and safely by tapping the outer side surface of the vertical plate 5.

[0033] Secondly, the bottom end of the support tube 2 falls on the adjustable gasket 3, and the height is fine-tuned based on the inclined surface 6 of the wedge-shaped pad 4, which can achieve small and precise height adjustment, and the quality of top surface alignment is better.

[0034] The flexible gasket 12 is a rubber pad, which is laid on the top surface of the support frame 1 according to the placement position of the single cylinder of the hoisted large annular tube reactor, so as to set a flexible contact at the contact part of the reactor cylinder to prevent damage to the anti-corrosion coating when the cylinder position is adjusted.

[0035] The tire frame device is padded at the bottom of the frame body by an adjustable gasket 3. The adjustable gasket 3 based on the cross-shaped structure can adjust the inclination of the frame body in the width direction and the length direction. The adjustment does not require moving the frame body, which is simpler, more labor-saving, more efficient and safer, and has a better alignment and leveling effect, and can complete the installation and alignment of the tire frame efficiently and with high quality.

[0036] Embodiment 2:

[0037] The adjustable gasket 3 includes 4 first pads and 2 second pads. The second pads are located below the two central support tubes 2 for support, which is consistent with the structure of the adjustable gasket 3 in Example 1. The first pads are located at the four corners of the support frame. The first pads are based on the structure of the adjustable gasket 3 in Example 1. The outer ends of two relatively collinear wedge-shaped pads 4 are provided with edge plates 7. The edge plates 7 are horizontally extending metal plates. The edge plates 7 are penetrated by mounting holes 8. The mounting holes 8 are equipped with positioning rods. The positioning rods can be expansion bolts. If the bottom surface of the site is relatively easy to transport, anchor rods can also be used and directly driven into the ground to ensure that they will not move.

[0038] The top surface of the pad 9 is provided with three shallow grooves 10 at both ends and the center of the corresponding frame body, respectively. The shallow grooves 10 are used to place the adjustable gaskets 3. The shallow grooves 10 at both ends are provided with two groups of clearance holes 11, each group of clearance holes 11 has two, and the positions of the two groups of clearance holes 11 correspond to the positions of the edge plate 7, respectively, and can cover the possible positions of the mounting holes 8 during the adjustment process, so as to facilitate the downward insertion of the positioning rod into the ground of the site. After the fine-tuning is completed and the top surface of the supporting frame 1 is leveled, the adjustable frame is fixed to assist the frame body to remain in this state.

[0039] The support frame 1 is provided with a plurality of hook rods 13 on both sides along its length direction, and the bottom ends of the hook rods 13 extend downward and outward at an angle. The flexible gasket 12 is a rubber pad, and a plurality of hanging holes are provided at the edge of the flexible gasket 12. By hooking the hanging holes on both sides on the hook rods 13, the flexible gasket 12 can be limited relative to the top of the frame body, and the movement and falling of the flexible gasket 12 during adjustment can be avoided when the monotube is hoisted and placed.
