Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessels, in particular to an auxiliary fixing structure for pressure vessel inspection. Background Art

[0002] A pressure vessel refers to equipment in industrial production that has specific process functions and withstands a certain pressure. Storage and transportation containers, reaction vessels, heat exchange containers and separation containers are all pressure vessels. The stability of existing auxiliary devices for pressure vessel inspection is poor. During the inspection process, the auxiliary device may move on the top of the pressure vessel, causing damage to the top of the pressure vessel, which is not conducive to the implementation of the pressure detection process.

[0003] After searching, the Chinese patent document application number: 202320338106.7 discloses an anti-tilting auxiliary fixing structure for pressure vessel inspection, including a pressure vessel inspection frame, an instrument block is fixedly connected to the surface of the pressure vessel inspection frame, and an inspection mechanism is arranged on the surface of the pressure vessel inspection frame. The instrument block is arranged on the surface of the instrument block, and an instrument for measuring the working pressure is fixed on the surface of the instrument block. The instrument block is small in size, which is convenient for being placed inside the pressure vessel to measure the working pressure of the vessel. A detachable and adjustable support rod is arranged on the surface of the pressure vessel inspection frame. When in use, it can be assembled and started to be used. After use, it is simple and convenient to disassemble and store it, which is convenient for transportation and reuse. At the same time, the adjustable support rod can be adjusted to be suitable for pressure vessels of various sizes, and has a wider range of use.

[0004] However, the above-mentioned auxiliary fixing structure for anti-tilting pressure vessel inspection still has the following defects:

The instrument block is small in size and is convenient for being placed inside the pressure vessel to measure the working pressure of the vessel. A detachable and adjustable support rod is set on the surface of the pressure vessel inspection frame, which can be assembled and used when in use. However, when the device is in use, the pressure vessel can only be inspected vertically. In the case of some pressure vessels that require horizontal inspection, the device may need to be replaced to meet the requirements. Therefore, we need an auxiliary fixing structure for pressure vessel inspection to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: an auxiliary fixing structure for pressure vessel inspection, comprising a base 1, fixed seats 6 are installed on both side surfaces of the base 1, a mounting groove 601 is provided on the top of the fixed seat 6, a lifting plate 7 is installed above the mounting groove 601 through a lifting assembly, a clamping assembly is installed on the upper end of the lifting plate 7, a fixing assembly is arranged below the clamping assembly, a rotating assembly is arranged inside the clamping assembly, a moving groove 4 for pressure vessel inspection movement is opened on the surface of the base 1, the fixing assembly is arranged above the moving groove 4, the clamping assembly comprises a second driving motor 8, a telescopic rod 10 and a clamping block 11, the output shaft of the second driving motor 8 is connected to a turntable through a coupling, the turntable is embedded in the lifting plate 7, one end of the telescopic rod 10 is fixedly installed on the surface center of the turntable, and the other end of the telescopic rod 10 is fixedly connected to one end of the clamping block 11;

[0023] When in use, the height of the lifting plate 7 is adjusted to make the clamping block 11 adapt to the top or side of the pressure vessel, and then the telescopic rod 10 is extended and retracted to make the clamping block 11 fit tightly against the surface of the pressure vessel, thereby achieving a stable fixation of the pressure vessel. Moreover, since the clamping block 11 can move with the extension and retraction of the telescopic rod 10, the pressure vessel can be effectively fixed even if it is in a horizontal position. The clamping direction of the clamping block 11 can be changed by rotating the second drive motor 8, so that a horizontal pressure vessel can also be clamped and fixed.

[0024] The two opposite sides of the two clamping blocks 11 are each provided with an arc-shaped surface, and the clamping surface of the clamping block 11 is fitted with a second anti-slip pad 12. The fitting installation of the second anti-slip pad 12 can increase the friction between the clamping block 11 and the pressure vessel, effectively preventing slippage due to vibration or external force during the inspection process. Especially when dealing with pressure vessels with relatively smooth surfaces, the role of the anti-slip pad is more significant, ensuring the stability and safety of clamping.

[0025] The fixing assembly includes a first drive motor 2, a bidirectional threaded rod 3 and a moving block 5. The base of the first drive motor 2 is fixedly installed on one side of the base 1. The output shaft of the first drive motor 2 is fixedly connected to one end of the bidirectional threaded rod 3. The other end of the bidirectional threaded rod 3 passes through the moving groove 4 and is fixedly installed on the inner wall of one side of the moving groove 4 through a bearing. The two moving blocks 5 move relative to each other on the bidirectional threaded rod 3. By driving the bidirectional threaded rod 3 to rotate by the first drive motor 2, the two moving blocks 5 can move relative to or away from each other in the moving groove 4, so that the auxiliary fixing structure can be quickly adjusted according to different pressure vessel sizes and inspection requirements, thereby realizing effective fixation of pressure vessels of different specifications.

[0026] A threaded hole 502 is provided at the bottom end of the moving block 5, and the bidirectional threaded rod 3 passes through the threaded hole 502 and is threadedly connected to the moving block 5. The surface of the moving block 5 is fitted with a first anti-slip pad 501. Through the threaded connection, the moving block 5 can fit tightly on the bidirectional threaded rod 3 to ensure that it is not prone to shaking or falling off during movement. The presence of the first anti-slip pad 501 can also reduce the direct friction between the moving block 5 and the base 1, thereby reducing wear and extending the service life of the entire auxiliary fixing structure.

[0027] First through grooves 603 are provided on both sides of the interior of the mounting groove 601, and second through grooves 702 are provided on both sides of the bottom end of the lifting plate 7. The first through groove 603 and the second through groove 702 are arranged opposite to each other, and round rods 602 are movably installed in the first through groove 603 and the second through groove 702. Through the movably installed round rods 602 in the first through groove 603 and the second through groove 702, a stable connection structure is formed between the lifting plate 7 and the mounting groove 601, which can effectively prevent the lifting plate 7 from shaking or deflecting during the lifting process, thereby enhancing the stability of the entire auxiliary fixing structure.

[0028] A third drive motor slot 606 is provided at the center of the surface of the mounting slot 601, a third drive motor 604 is fixedly installed inside the third drive motor slot 606, a screw 605 is fixedly installed on the output shaft of the third drive motor 604, a screw hole 701 is provided at the center of the bottom end of the lifting plate 7, one end of the screw 605 is threadedly rotatably installed in the screw hole 701, the screw 605 is driven to rotate by the third drive motor 604, and since the screw 605 is threadedly connected to the screw hole 701 at the bottom end of the lifting plate 7, precise control of the lifting and lowering movement of the lifting plate 7 can be achieved, so that the operator can accurately adjust the height of the lifting plate 7 as needed, thereby adapting to pressure vessels of different heights or sizes.

[0029] The rotating assembly includes an electric push rod 9, a piston rod end of the electric push rod 9 is fixedly connected to one end of a clamping block 11, a base of the electric push rod 9 is fixedly connected to one side of the surface of the turntable, and the electric push rod 9 is arranged at the upper end of the telescopic rod 10. The piston rod end of the electric push rod 9 is fixedly connected to one end of the clamping block 11, so that the clamping block 11 can move with the extension and retraction of the electric push rod 9, and the second drive motor 8 drives the turntable to rotate so that the electric push rod 9 can flexibly adjust its working angle and direction.
