[0016] The present invention provides a fastening fixture suitable for a tower-type metal pressure vessel through improvement, which has the following improvements and advantages compared with the prior art: First, the present invention provides a fastening mechanism. When the first mounting seat and the second mounting seat are closed, the clamping seat can be moved between the two connecting flanges. Then, the cylinder is started, and the cylinder drives the multiple clamping blocks to move upward or downward, so that the two connecting flanges can be clamped up and down. At the same time, the side wall of the clamping seat is in contact with the connecting flanges, and the two connecting flanges can be clamped horizontally between the multiple clamping seats, thereby achieving the effect of fastening and supporting pressure vessels and connecting flanges of different sizes. Secondly, the present invention is provided with a driving mechanism and a pressurizing mechanism. The oil tank delivers the hydraulic oil into the interior of the oil cylinder body through an oil inlet pipe and a check valve. As the hydraulic oil increases, the sealing plate will drive the force-applying shaft to move inside the oil cylinder body, thereby driving the clamp seat to move in the direction of the pressure vessel and the connecting flange. First, the pressure plate will contact the side wall of the connecting flange, and the pressure plate will be squeezed by the connecting flange and move toward the inside of the placement groove, thereby driving the pressurizing rod to move inside the pressurizing port. Since the pressurizing port is connected to the inside of the oil cylinder body, the pressurizing rod will pressurize the inside of the oil cylinder body again when it moves inside the pressurizing port. The pressure inside the oil cylinder body becomes larger. At this time, the extrusion force of the force-applying shaft and the clamp seat on the pressure vessel and the connecting flange will also be greater, thereby achieving the ability to clamp connecting flanges of different sizes while also making the clamping more secure. Thirdly, the present invention is provided with a locking mechanism. When the pressure port does not correspond to the position of the fixing bolt and the fixing nut, the larger positioning groove allows the fixing bolt and the fixing nut to move to the inside of the positioning groove first. As the locking block moves, the locking block is squeezed between the locking block and the fixing bolt and the fixing nut to rotate. After the locking block rotates, the fixing bolt and the fixing nut can move to the inside of the locking groove. This achieves the effect of automatically aligning the fixing bolt and the fixing nut while preventing them from falling off. Fourthly, the present invention is provided with a connection mechanism. When it is necessary to separate the mounting seat 1 from the mounting seat 2, the knob can be rotated, and the knob drives the rotating shaft and the transmission gear to rotate. The transmission gear meshes with the transmission rack for transmission, and the transmission rack moves inside the rack groove, thereby driving the base 1 to leave the inside of the base 2, and then the mounting seat 1 and the mounting seat 2 can be separated, achieving the effect of facilitating the fixed connection and separation of the mounting seat 1 and the mounting seat 2; Fifth: The present invention starts the hydraulic support rod by setting up the support mechanism, and the hydraulic support rod can drive the mounting base 1 and the mounting base 2 to move up and down, so as to fasten and support the pressure vessels and connecting flanges at different heights, and at the same time move the output end of the hydraulic support rod to the inside of the slot, and then the base 1 and the base 2 can be fixedly connected.

The clamping seat 8 is also provided with a locking mechanism. When the mounting seat 1 and the mounting seat 2 are closed, the clamping seat 8 can be moved between the two connecting flanges 5, and then the cylinder 18 is started. The cylinder 18 drives the multiple clamping blocks 17 to move upward or downward, so that the two connecting flanges 5 can be clamped up and down. At the same time, the side wall of the clamping seat 8 is in contact with the connecting flange 5. The two connecting flanges 5 can be horizontally clamped between the multiple clamping seats 8, thereby achieving the effect of fastening and supporting pressure vessels 4 and connecting flanges 5 of different sizes; The driving mechanism includes an oil tank 11, an oil inlet pipe 12, a check valve 13, an oil inlet pipe 2 14, a sealing plate 15 and a sealing member 16.

The interior of the force shaft 10 is filled with hydraulic oil. The oil inlet pipe 12 is fixedly mounted on the top of the oil tank 11 and is located inside the mounting seat 1 and the mounting seat 2. The check valve 13 is embedded in the cylinder body 9. The oil inlet pipe 12 is connected to the check valve 13. The oil inlet pipe 12 is connected to the interior of the cylinder body 9 through the check valve 13.

Through the arrangement of the driving mechanism, the oil tank 11 delivers the hydraulic oil into the interior of the oil cylinder body 9 through the oil inlet pipe 12 and the check valve 13. With the increase of the hydraulic oil, the sealing plate 15 will drive the force shaft 10 to move inside the oil cylinder body 9, thereby driving the clamp seat 8 to move toward the direction of the pressure vessel 4 and the connecting flange 5; The pressurizing mechanism includes a pressurizing rod 30, a sealing member 31 and a pressure plate 33. A pressurizing port 29 is provided on the force applying shaft 10 and the sealing plate 15. The pressurizing port 29 is a circular groove. The pressurizing rod 30 is a cylindrical structure. The pressurizing rod 30 is movably installed inside the pressurizing port 29. The sealing member 31 is an annular structure. The sealing member 31 is embedded and installed on the side wall of the pressurizing rod 30. A placement groove 32 is provided on the inner wall of the clamp seat 8. The placement groove 32 is a circular groove. One end of the pressurizing rod 30 passes through the side wall of the clamp seat 8 and is located inside the placement groove 32.

[0022] like Figure 2 , Figure 5 as well as Figure 6As shown, the fastening mechanism includes two groups of locking blocks 19, a locking seat 22, a torsion spring shaft 24, a limit block 25, a rotating block 26, an extrusion block 27 and a connecting rod 28. The two groups of fastening mechanisms are respectively arranged inside the two clamping blocks 17. The locking block 19 is a circular structure.

As the locking block 19 moves, the locking block 19 is squeezed between the fixing bolt 6 and the fixing nut 7 to rotate. After the locking block 19 rotates, the fixing bolt 6 and the fixing nut 7 can be moved to the inside of the locking groove 20, so that the fixing bolt 6 and the fixing nut 7 can be fixed to prevent them from falling off, and the effect of automatic alignment can be achieved.

When the fixing bolt 6 and the fixing nut 7 are aligned, the rotating block 26 cannot be driven by the locking block 19 to rotate in the opposite direction inside the locking seat 22, thereby further avoiding the situation where the fixing bolt 6 and the fixing nut 7 fall off after vibration.

At this time, the inclined surface of the connecting block 36 will contact the mounting seat 2, so that the connecting block 36 is squeezed and moved to the inside of the mounting groove 35, and at the same time, the spring on the movable rod 39 is squeezed. Then the spring releases the elastic force, and the connecting block 36 can be moved to the inside of the limiting groove 37.

[0025] Specific implementation steps: when the mounting seat 1 and the mounting seat 2 are closed, the clamping seat 8 can be moved between the two connecting flanges 5, and then the cylinder 18 is started, and the cylinder 18 drives the multiple clamping blocks 17 to move upward or downward, so that the two connecting flanges 5 can be clamped up and down, and at the same time, the side wall of the clamping seat 8 is in contact with the connecting flange 5, and the two connecting flanges 5 can be horizontally clamped between the multiple clamping seats 8, so as to achieve the effect of fastening and supporting pressure vessels 4 and connecting flanges 5 of different sizes; At the same time, a driving mechanism and a pressurizing mechanism are provided. The oil tank 11 sends hydraulic oil into the interior of the cylinder body 9 through the oil inlet pipe 12 and the check valve 13. As the hydraulic oil increases, the sealing plate 15 will drive the force-applying shaft 10 to move inside the cylinder body 9, thereby driving the clamp seat 8 to move toward the direction of the pressure vessel 4 and the connecting flange 5. First, the pressure plate 33 will contact the side wall of the connecting flange 5, and the pressure plate 33 will be squeezed by the connecting flange 5 and move toward the inside of the placement groove 32, thereby driving the pressurizing rod 30 to move inside the pressurizing port 29. Since the pressurizing port 29 is connected to the interior of the cylinder body 9, the pressurizing rod 30 will pressurize the interior of the cylinder body 9 again when it moves inside the pressurizing port 29, and the internal pressure of the cylinder body 9 increases. At this time, the extrusion force of the force-applying shaft 10 and the clamp seat 8 on the pressure vessel 4 and the connecting flange 5 will also be greater, thereby achieving the ability to clamp connecting flanges 5 of different sizes while also making the clamping more secure.
