Description

Technical Field

[0001] This utility model belongs to the field of pressure vessel testing technology, specifically relating to an anti-tilting pressure vessel testing fixing device. Background Technology

[0002] A pressure vessel is a sealed container capable of withstanding pressure. Pressure vessels have a wide range of applications, playing a vital role in many sectors, including industry, civil use, military, and scientific research. They are most commonly used in the chemical and petrochemical industries. In these fields, pressure vessels are primarily used for heat transfer, mass transfer, and reaction processes, as well as for storing and transporting pressurized or liquefied gases. During pressure vessel manufacturing, the cylinder is a common structure, formed by bending and welding sheet metal. However, due to the thickness and weight of the sheet metal, as well as the stress generated during welding, the surface of the welded cylinder is often not perfectly smooth, making it difficult to connect to the curved base. Therefore, the surface smoothness of the welded cylinder needs to be checked using inspection tools.

[0003] The prior art patent publication number CN222371382U describes a fixing device for pressure vessel testing. This patent features a fixing mechanism that stably clamps and fixes the pressure vessel, while also facilitating adjustment for pressure vessels of different heights and sizes. This improves the stability of the pressure vessel during fixing and enhances the accuracy of the testing results. A dust removal mechanism is also included to facilitate cleaning dust from the pressure vessel surface, making testing easier and subsequent storage more convenient. However, in practical use, the following shortcomings remain: Practically speaking, this device relies on clamping mechanisms on both sides to fix the pressure vessel and lacks a specific anti-tilting limiting mechanism. When the center of gravity of the pressure vessel shifts, such as due to uneven loading, it is prone to tipping over.

[0004] Therefore, a pressure vessel detection and fixing device that prevents tilting is needed to solve the problem of easy tipping caused by the lack of a targeted anti-tilting limit mechanism in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide an anti-tilting pressure vessel detection and fixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure vessel detection and fixing device for preventing tilting, comprising a fixing frame, a mounting plate, a clamping mechanism and an anti-tilting mechanism, wherein supporting legs are symmetrically fixedly connected around the bottom surface of the fixing frame, the mounting plate is symmetrically fixedly connected inside the fixing frame, the clamping mechanism is disposed above the inside of the fixing frame via the mounting plate, and the anti-tilting mechanism is disposed below the clamping mechanism.

[0007] It should be noted that the clamping mechanism consists of a first fixed ring, a lead screw, a threaded block, a connecting shaft, a connecting block, a rotating ring, a connecting plate, a second fixed ring, a fixed shaft, a connecting rod, a fixed plate, a limiting frame, and a rotating shaft. The first fixed ring is fixedly connected between two mounting plates. The lead screw is rotatably connected to the upper front side of the first fixed ring. A handle is fixedly connected to the left end of the lead screw. The threaded block is threadedly connected to the outside of the lead screw. The connecting shaft is rotatably connected to the lower part of the threaded block, and the connecting block is rotatably connected to the lower part of the connecting shaft.

[0008] It is further worth noting that the rotating ring is rotatably connected to the inside of the first fixed ring, the connecting block is fixedly connected to the front side of the rotating ring, there are three connecting plates, which are symmetrically fixedly connected to the top of the rotating ring, and the second fixed ring is fixedly connected to the top of the connecting plates.

[0009] Furthermore, it should be noted that the fixed shaft is symmetrically fixedly connected above the first fixed ring, one end of the connecting rod is rotatably connected to the outside of the fixed shaft, the fixed disk is rotatably connected to the other end of the fixed shaft, and an anti-slip layer is fixedly installed on the outside of the fixed disk.

[0010] In a preferred embodiment, the limiting frame is disposed between the second fixed ring and the rotating ring, and is rotatably connected to the second fixed ring and the rotating ring respectively via a rotating shaft, and the connecting rod is slidably connected inside the limiting frame.

[0011] In a preferred embodiment, the anti-tilt mechanism consists of a third fixing ring, connecting columns, a baffle, an arc plate, and a spring. The third fixing ring is fixedly connected between two mounting plates, and there are three connecting columns that are symmetrically slidably connected inside the third fixing ring.

[0012] In a preferred embodiment, the baffle is fixedly connected to the end of the connecting column away from the center of the third fixing ring, the arc-shaped plate is fixedly connected to the other end of the connecting column, and the spring is symmetrically fixedly connected between the arc-shaped plate and the inner wall of the third fixing ring.

[0013] In a preferred embodiment, an anti-slip pad is provided on the inner side of the arc-shaped plate.

[0014] Compared with the prior art, the anti-tilting pressure vessel detection and fixing device provided by this utility model has at least the following beneficial effects:

[0015] (1) The clamping mechanism is designed with a three-point clamping design. The three fixed plates are evenly distributed and can apply clamping force to the pressure vessel from different directions, so that the pressure vessel is subjected to balanced force and avoids excessive local force that may cause the vessel to deform or be damaged. The anti-slip layer on the outside of the fixed plate can significantly increase the friction between the plate and the outer wall of the pressure vessel, effectively preventing the pressure vessel from sliding during the inspection process, further improving the stability of clamping and fixing, and ensuring the smooth progress of the inspection work.

[0016] (2) The anti-tilting mechanism is set up to provide elastic support and limit the bottom of the pressure vessel through the cooperation of three sets of springs and arc plates. Moreover, the elasticity of the springs can automatically adjust the position of the arc plates according to the diameter of the pressure vessel, so as to always maintain stable support for the pressure vessel, effectively preventing the pressure vessel from tilting or falling over due to the shift of the center of gravity or external interference during the testing process, and ensuring testing safety.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a pressure vessel detection and fixing device for preventing tilting, including a fixing frame 1, a mounting plate 2, a clamping mechanism 3 and an anti-tilting mechanism 4. Support legs are symmetrically fixedly connected around the bottom surface of the fixing frame 1. The mounting plate 2 is symmetrically fixedly connected inside the fixing frame 1. The clamping mechanism 3 is set inside the fixing frame 1 through the mounting plate 2. The anti-tilting mechanism 4 is set below the clamping mechanism 3.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the clamping mechanism 3 consists of a first fixed ring 301, a lead screw 302, a threaded block 303, a connecting shaft 304, a connecting block 305, a rotating ring 306, a connecting plate 307, a second fixed ring 308, a fixed shaft 309, a connecting rod 310, a fixed plate 311, a limiting frame 312, and a rotating shaft 313. The first fixed ring 301 is fixedly connected between the two mounting plates 2. The lead screw 302 is rotatably connected to the upper front side of the first fixed ring 301. A handle is fixedly connected to the left end of the lead screw 302. The threaded block 303 is threadedly connected to the outside of the lead screw 302. The connecting shaft 304 is rotatably connected to the lower part of the threaded block 303. The connecting block 305 is rotatably connected to the lower part of the connecting shaft 304.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the rotating ring 306 is rotatably connected to the inside of the first fixed ring 301, the connecting block 305 is fixedly connected to the front side of the rotating ring 306, there are three connecting plates 307, which are symmetrically fixedly connected to the top of the rotating ring 306, and the second fixed ring 308 is fixedly connected to the top of the connecting plates 307.

[0026] The connecting plate 307 drives the second fixed ring 308 to rotate synchronously. Since the limiting frame 312 is rotatably connected between the rotating ring 306 and the second fixed ring 308 through the rotating shaft 313, the rotation of the limiting frame 312 drives the internal connecting rod 310 to slide, which in turn drives the fixed plate 311 at the end to move, thus controlling the position of the three fixed plates 311.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the fixed shaft 309 is symmetrically fixedly connected above the first fixed ring 301, one end of the connecting rod 310 is rotatably connected to the outside of the fixed shaft 309, the fixed disk 311 is rotatably connected to the other end of the fixed shaft 309, and an anti-slip layer is fixedly installed on the outside of the fixed disk 311.

[0028] The anti-slip layer increases the friction between the fixed plate 311 and the outer wall of the pressure vessel, thereby improving the stability of the fixation.

[0029] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the limiting frame 312 is located between the second fixed ring 308 and the rotating ring 306, and is rotatably connected to the second fixed ring 308 and the rotating ring 306 respectively through the rotating shaft 313, and the connecting rod 310 is slidably connected inside the limiting frame 312.

[0030] The rotation of the limiting frame 312 causes the internal connecting rod 310 to slide, which in turn moves the fixed plate 311 at the end. This allows for control of the position of the fixed plate 311 to accommodate pressure vessels of different diameters.

[0031] As can be seen from the above working process: the clamping mechanism 3 adopts a three-point clamping design, with three fixed disks 311 evenly distributed, which can apply clamping force to the pressure vessel from different directions, so that the pressure vessel is subjected to balanced force and avoids excessive local force that may cause deformation or damage to the vessel; the anti-slip layer on the outside of the fixed disk 311 can significantly increase the friction between it and the outer wall of the pressure vessel, effectively preventing the pressure vessel from sliding during the testing process, further improving the stability of clamping and fixing, and ensuring the smooth progress of the testing work.

[0032] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the anti-tilt mechanism 4 consists of a third fixed ring 401, a connecting column 402, a baffle 403, an arc plate 404, and a spring 405. The third fixed ring 401 is fixedly connected between the two mounting plates 2, and there are three connecting columns 402, which are symmetrically slidably connected inside the third fixed ring 401.

[0033] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the baffle 403 is fixedly connected to the end of the connecting column 402 away from the center of the third fixing ring 401, the arc plate 404 is fixedly connected to the other end of the connecting column 402, and the spring 405 is symmetrically fixedly connected between the arc plate 404 and the inner wall of the third fixing ring 401.

[0034] The arc-shaped plate 404 can better contact and connect with the outer wall of the pressure vessel, improving the stability of the pressure vessel; the elastic action between the three sets of springs 405 can generate pressure on the pressure vessel, improving the stability of the pressure vessel.

[0035] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth noting that the inner side of the curved plate 404 is provided with an anti-slip pad.

[0036] This solution has the following working process: During use, the operator places the pressure vessel to be tested into the device from above the fixed frame 1, so that the bottom of the pressure vessel first contacts the arc plate 404 in the anti-tilt mechanism 4. Since the connecting column 402 is symmetrically slidably connected to the inside of the third fixed ring 401, and the spring 405 is fixedly connected between the arc plate 404 and the inner wall of the third fixed ring 401, the weight of the pressure vessel will push the arc plate 404 to move away from the center of the third fixed ring 401, and the connecting column 402 will slide accordingly. The spring 405 will be compressed and generate a reverse elastic force. Under the action of the spring 405, the three arc plates 404 will tightly fit against the outer wall of the bottom of the pressure vessel, initially supporting and anti-tilt limiting the pressure vessel.

[0037] After the initial placement of the pressure vessel is completed, the handle at the left end of the lead screw 302 in the clamping mechanism 3 is rotated. The lead screw 302 is rotatably connected to the front side above the first fixed ring 301. The threaded block 303 connected externally will move along the lead screw axis as the lead screw rotates. The connecting shaft 304 rotatably connected below the threaded block 303 drives the connecting block 305 to move. The connecting block 305 is fixedly connected to the front side of the rotating ring 306 inside the first fixed ring 301. Therefore, the movement of the connecting block 305 will drive the rotating ring 306 to rotate inside the first fixed ring 301. The three connecting plates 307 symmetrically fixed above the rotating ring 306 will drive the second fixed ring 308 to rotate synchronously. Due to the limiting frame 312 The connecting rod 310 is rotatably connected to the second fixed ring 308 and the rotating ring 306 via the rotating shaft 313, and is slidably connected inside the limiting frame 312. At the same time, one end of the connecting rod 310 is rotatably connected to the outside of the fixed shaft 309 above the first fixed ring 301. The rotation of the rotating ring 306 and the second fixed ring 308 will drive the limiting frame 312 to rotate, thereby causing the connecting rod 310 to slide inside the limiting frame 312 and rotate around the fixed shaft 309. The fixed plate 311 rotatably connected to the other end of the connecting rod 310 will move towards the pressure vessel until the anti-slip layer on the outside of the three fixed plates 311 is tightly attached to the outer wall of the middle part of the pressure vessel, thereby achieving a firm clamping and fixing of the pressure vessel.

[0038] In summary: The clamping mechanism 3, employing a three-point clamping design with three evenly distributed fixing discs 311, applies clamping force to the pressure vessel from different directions, ensuring balanced force distribution and preventing excessive localized stress that could lead to deformation or damage. The anti-slip layer on the outside of the fixing discs 311 significantly increases friction with the outer wall of the pressure vessel, effectively preventing slippage during testing and further enhancing clamping stability to ensure smooth testing. The anti-tilting mechanism 4, through the cooperation of three sets of springs 405 and an arc-shaped plate 404, provides elastic support and limit to the bottom of the pressure vessel. Furthermore, the elasticity of the springs 405 automatically adjusts the position of the arc-shaped plate 404 according to the diameter of the pressure vessel, maintaining stable support and effectively preventing tilting or tipping due to center of gravity shift or external interference during testing, thus ensuring testing safety.
