[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 and Figure 2This utility model provides an embodiment of an anti-tilting pressure vessel inspection auxiliary fixing structure, comprising an auxiliary platform 1. The auxiliary platform 1 is the basic support component of the entire pressure vessel inspection auxiliary fixing structure, providing a stable base and ensuring the overall stability of the equipment. The auxiliary platform 1 has an internal chamber 2 for accommodating and installing other mechanical components. A motor 3 is fixedly connected to the bottom inner wall of the chamber 2. The motor 3 is the power source of the entire structure, responsible for converting electrical energy into mechanical energy. A rotating shaft 4 is fixedly connected to the drive end of the motor 3. A rotating plate 5 is fixedly connected to the outside of the rotating shaft 4. The rotating shaft 4 connects the motor 3 and the rotating plate 5, ensuring that the rotational power output by the motor 3 can be effectively transmitted to the rotating plate 5. Transmission plates 6 are rotatably connected to the left and right sides of the bottom of the rotating plate 5. Sliding blocks 7 are rotatably connected to the outer sides of the two transmission plates 6. The transmission plates 6 are an intermediary structure connecting multiple moving parts, responsible for transmitting the rotational motion of the rotating plate 5 to the sliding blocks 7. Two I-shaped groove blocks 8 are fixedly connected to the bottom inner wall of chamber 2. The outer wall of sliding block 7 is slidably connected to the inner wall of I-shaped groove blocks 8, and sliding block 7 moves smoothly left and right under the guidance of I-shaped groove blocks 8. A transmission column 9 is fixedly connected to the top of sliding block 7, and an L-shaped plate 10 is fixedly connected to the top of each of the two transmission columns 9. The transmission column 9 is the component connecting sliding block 7 and L-shaped plate 10, and is responsible for converting the movement of sliding block 7 into the movement of L-shaped plate 10. Two cylinders 11 are fixedly connected to the adjacent sides of the two L-shaped plates 10, and an arc-shaped plate 12 is fixedly connected to the driving end of cylinder 11. The arc-shaped plate 12 is used to clamp pressure vessels of different sizes and can move inward and outward according to the action of cylinder 11, thereby realizing the clamping and release of pressure vessels so that various positions of pressure vessels can be inspected.

[0032] The top of the auxiliary platform 1 is slidably connected to an auxiliary component to reduce the risk of tilting and wear of the pressure vessel during inspection. The top of the auxiliary platform 1 has an elongated groove 13, and the outer walls of the two drive columns 9 are slidably connected to the inner wall of the elongated groove 13. The elongated groove 13 provides guidance for the drive columns 9, further increasing the stability when clamping the pressure vessel. The bottom sides of the two L-shaped plates 10 are in contact with the top side of the auxiliary platform 1. The inner, opposite sides of the two drive plates 6 are rotatably connected to the outer walls of the two drive columns 9, and the top side of the rotating plate 5 is in contact with the top inner wall of the chamber 2.

[0033] Reference Figure 1 , Figure 3 and Figure 4The elongated groove 13 has sliding grooves 14 on both its front and rear inner walls. The auxiliary components include two sliding rods 15, whose outer walls are slidably connected to the inner walls of the two sliding grooves 14. The sliding grooves 14 serve as guide structures between the placement plate 17 and the sliding rods 15, and have internal channels to facilitate the movement of the sliding rods 15. Support rods 16 are fixedly connected to the top of the middle section of each sliding rod 15, and the tops of the two support rods 16 are fixedly connected to the placement plate 17. The sliding rods 15 connect the placement plate 17 and the support rods 16, transmitting the movement of the placement plate 17 to the support rods 16. The placement plate 17 is the basic component used to support the pressure vessel.

[0034] The opposite sides of the two sliding rods 15 contact the inner walls of the left and right sides of the two sliding grooves 14, and the outer sides of the two support rods 16 contact the inner side of the elongated groove 13. The bottom side of the placement plate 17 contacts the top side of the auxiliary platform 1, and a support frame 18 is fixedly connected to the front end of the placement plate 17. A horizontal warning device 19 is rotatably connected to the top inner wall of the support frame 18. When the pressure vessel is tilted or unevenly placed, it will deviate from the horizontal warning device 19, thereby reminding the operator to level the pressure vessel. Telescopic columns 20 are fixedly connected to the four corners of the bottom of the auxiliary platform 1. The telescopic columns 20 can adjust the height of the platform as needed to accommodate pressure vessels of different heights.

[0035] Working principle: By turning on the motor 3, power is generated to drive the rotating shaft 4, which in turn drives the rotating plate 5 to rotate. The rotation of the rotating plate 5 drives the transmission plate 6 to rotate. With the guidance of the I-shaped groove block 8, the rotation of the transmission plate 6 is converted into the left and right movement of the sliding block 7. The left and right movement of the sliding block 7 drives the left and right movement of the transmission column 9. The left and right movement of the transmission column 9 drives the left and right movement of the L-shaped plate 10. The left and right movement of the L-shaped plate 10 drives the left and right movement of the cylinder 11. The left and right movement of the cylinder 11 drives the arc plate 12 to move inward and outward, thereby achieving the clamping of pressure vessels of different sizes. When inspecting the pressure vessel, by controlling the cylinder 11 to generate power to drive the arc plate 12 to move left and right, the clamping and release of the arc plate 12 can be controlled when inspecting the upper and lower parts of the pressure vessel, so as to carry out a comprehensive inspection of the pressure vessel and avoid the omission of inspection of the clamped parts.

[0036] By placing the pressure vessel on the placement plate 17, when the arc plate 12 clamps the pressure vessel, the pressure vessel is subjected to pressure, which causes the placement plate 17 to shift. The sliding groove 14 allows the sliding rod 15 to slide smoothly, and the connection between the placement plate 17 and the sliding rod 15 by the support rod 16 allows the movement of the placement plate 17 to proceed smoothly. This avoids the risk of the pressure vessel tilting or bottom wear due to excessive friction between the pressure vessel and the placement part during clamping.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
