Description

Technical Field

[0001] This utility model relates to the field of support frame technology, and in particular to a special support frame for defect detection of large reaction pressure vessels. Background Technology

[0002] In the chemical, petroleum, and power industries, reaction pressure vessels are core equipment. In chemical synthesis, pressure vessels provide specific pressure and temperature environments for chemical reactions, facilitating smooth reactions and producing various chemical products. In petroleum refining, they are used in critical processes such as crude oil fractionation and hydrogenation. The safety and stability of their operation directly affect the continuity of the entire production process and product quality. Once a malfunction occurs, it may lead to serious production accidents and cause huge economic losses. The temporary support structures used in the past for testing are usually temporarily built according to the size and shape of specific containers, which is difficult to adapt to different specifications and types of pressure vessels. The support requirements for spherical pressure vessels and cylindrical pressure vessels are quite different, and traditional temporary supports cannot be quickly switched, resulting in low testing efficiency.

[0003] With the continuous advancement of testing technology, the precision requirements for pressure vessel defect detection are becoming increasingly stringent. Advanced non-destructive testing technologies, such as phased array ultrasonic testing and time-of-flight diffraction ultrasonic testing, require the pressure vessel to remain absolutely stable during the testing process. Dedicated support frames can provide a stable support platform for high-precision testing. However, current dedicated support frames for vessels cannot guarantee the stability of the vessel during use, leading to inaccurate test data. Inspectors are forced to repeatedly test the same area to obtain reliable data, requiring readjustment of the testing equipment and vessel position. This significantly extends the testing time, resulting in a substantial increase in the testing cycle and impacting production schedules. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special support frame for defect detection of large reaction pressure vessels. It aims to improve the problem in the existing technology that the stability of the vessel cannot be guaranteed, resulting in inaccurate detection data. As a result, the inspectors have to repeatedly inspect the same part, which leads to a significant extension of the inspection cycle and affects the production schedule.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a special support frame for defect detection of large reaction pressure vessels, including support bars, with L-shaped connecting plates fixedly connected to adjacent sides of two support bars, a U-shaped bracket fixedly connected to the top of the L-shaped connecting plates, an arc-shaped plate fixedly connected to the left and right sides of the inside of the U-shaped bracket, U-shaped plates fixedly connected to the front and rear sides of the U-shaped bracket, telescopic rods fixedly connected to the top left and right sides of the support bars, the output end of the telescopic rods penetrating the bottom of the U-shaped plates and fixedly connected to an arc-shaped rod, an L-shaped connecting plate fixedly connected to the middle of the inner side of the U-shaped bracket, an arc-shaped plate fixedly connected to the top of the L-shaped connecting plate, and an adjustment mechanism provided at the bottom of the support bars for adjusting the height of the support frame.

[0006] As a further description of the above technical solution:

[0007] The adjustment mechanism includes a base plate, the top of which is positioned at the bottom of a support bar. A support plate is fixedly connected to the top left side of the base plate, and a sliding rod is fixedly connected to the upper right side of the support plate. A rotating plate is fixedly connected to the bottom left side of the outer wall of the sliding rod. A cylinder is rotatably connected to the outer wall of the rotating plate. A rotating plate is rotatably connected to the output end of the cylinder. A movable sleeve is fixedly connected to the top of the rotating plate. A rotating inclined plate is rotatably connected to the top of the outer wall of the movable sleeve. A rotating inclined plate is rotatably connected to the other end of the rotating inclined plate. A lifting plate is rotatably connected to the top of the rotating inclined plate. A fixed plate is fixedly connected to the outer wall of each lifting plate.

[0008] As a further description of the above technical solution:

[0009] The top inner side of the arc-shaped rod is fixedly connected with an anti-slip strip 2, and the top of the arc-shaped plate 1 is fixedly connected with an anti-slip strip 1.

[0010] As a further description of the above technical solution:

[0011] Limiting posts are fixedly connected to both the left and right ends of the slide rod, and anti-slip pads are fixedly connected to the bottom of the base plate.

[0012] As a further description of the above technical solution:

[0013] Each of the adjacent base plates is fixedly connected with a reinforcing plate, and multiple reinforcing plates are fixedly connected at the same horizontal height.

[0014] As a further description of the above technical solution:

[0015] The inner side of the movable sleeve is slidably connected to the outer wall of the slide rod, and the top of the fixed plate is fixedly connected to the bottom left and right sides of the support bar.

[0016] As a further description of the above technical solution:

[0017] Protective plates are fixedly connected to the middle of the front and rear sides of the U-shaped bracket, and all of the protective plates adopt a symmetrical design.

[0018] As a further description of the above technical solution:

[0019] A controller is fixedly connected to the center of the top surface of the front support bar, and the controller is electrically connected to the telescopic rod and the cylinder respectively.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the surfaces of the first and second arc-shaped plates, together with the U-shaped bracket and the L-shaped connecting plate, support a pair of containers. A support bar is fixed on the U-shaped bracket. At this time, the telescopic rod fixedly connected to the support bar is activated, passes through the U-shaped plate, and pulls the arc-shaped rod downward. With the cooperation of the second anti-slip strip, it fits against the outer wall of the container for support and limitation. Therefore, it can effectively ensure that the container does not move during the support process and improve the practicality of the support frame.

[0022] 2. In this utility model, by fixing the base plate and the support plate, and opening the cylinder rotatably connected to the rotating plate one, while the rotating plate two moves, it drives the rotating inclined plate one and the rotating inclined plate two to move to the left, so that the rotating inclined plate two slowly comes to a vertical state. Then, the lifting plate and the fixed plate are moved upward, thereby adjusting the height of the container support frame. This makes it easier for operators to use the container and improves the effectiveness of the support frame. Attached Figure Description

[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] Please see the appendix Figure 2 and attached Figure 5 An embodiment of this utility model provides a special support frame for defect detection of large reaction pressure vessels, including support bars 1, L-shaped connecting plates 14 fixedly connected to adjacent sides of the two support bars 1, U-shaped brackets 6 fixedly connected to the top of the L-shaped connecting plates 14, arc plates 10 fixedly connected to the left and right sides of the inside of the U-shaped brackets 6, U-shaped plates 4 fixedly connected to the front and rear sides of the U-shaped brackets 6, telescopic rods 3 fixedly connected to the top left and right sides of the support bars 1, the output end of the telescopic rods 3 passes through the bottom of the U-shaped plates 4 and is fixedly connected to the arc rods 5, L-shaped connecting plates 13 fixedly connected to the middle of the inner side of the U-shaped brackets 6, arc plates 12 fixedly connected to the top of the L-shaped connecting plates 13, an adjustment mechanism 2 is provided at the bottom of the support bars 1, the adjustment mechanism 2 is used to adjust the height of the support frame, anti-slip strips 11 are fixedly connected to the top of the inner side of the arc rods 5, and anti-slip strips 9 are fixedly connected to the top of the arc plates 10.

[0032] Specifically, through the top of the L-shaped connecting plate 214, we can see a U-shaped bracket 6 being securely fixedly connected. This U-shaped bracket 6 serves as a support frame, and on its left and right sides, an arc-shaped plate 10 is fixedly connected. These two arc-shaped plates 10 enhance the structural strength of the U-shaped bracket 6. These two U-shaped plates 4 and the U-shaped bracket 6 form a stable frame structure, providing solid support for the subsequent installation of the telescopic rod 3 and the arc-shaped rod 5. These telescopic rods 3 serve as adjustable support components, with their output ends penetrating through the bottom of the U-shaped plate 4 and securely connected to an arc-shaped rod 5, allowing the arc-shaped rod 5 to be extended and retracted as needed. The addition of the arc-shaped plate 212 not only further enhances the stability of the structure but also increases the load-bearing capacity and protective effect of the entire structure.

[0033] Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 4 The adjustment mechanism 2 includes a base plate 202. The top of the base plate 202 is located at the bottom of the support bar 1. A support plate 205 is fixedly connected to the top left side of the base plate 202. A slide rod 204 is fixedly connected to the upper right side of the support plate 205. A rotating plate 211 is fixedly connected to the bottom left side of the outer wall of the slide rod 204. A cylinder 203 is rotatably connected to the outer wall of the rotating plate 211. A rotating plate 212 is rotatably connected to the output end of the cylinder 203. A movable sleeve 201 is fixedly connected to the top of the rotating plate 212. A rotating inclined plate 213 is rotatably connected to the top of the outer wall of the movable sleeve 201. A rotating inclined plate 214 is rotatably connected to the other end of the rotating inclined plate 213. A lifting plate 210 is rotatably connected to the top of the rotating inclined plate 214. A fixed plate 209 is fixedly connected to the outer wall of the lifting plate 210. Limiting posts 207 are fixedly connected to the left and right ends of the slide rod 204. An anti-slip pad 208 is fixedly connected to the bottom of the base plate 202.

[0034] Specifically, the support plate 205 not only provides support and a reliable connection point, but also has a slide rod 204 firmly fixedly connected to the upper right side of the support plate 205. The sliding component of the slide rod 204 provides guidance and support, and the movable sleeve 201 can slide along the slide rod 204, increasing the flexibility of the entire structure and making subsequent lifting operations smoother and more controllable. It will drive the rotating plate 212 and the movable sleeve 201 to slide along the slide rod 204, and through the transmission of the rotating inclined plate 213 and the rotating inclined plate 214, the lifting plate 210 will move up and down.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3Each adjacent base plate 202 is fixedly connected with a reinforcing plate 206. Multiple reinforcing plates 206 are fixedly connected at the same horizontal height. Protective plates 7 are fixedly connected to the middle of the front and rear sides of the U-shaped bracket 6. Multiple protective plates 7 are symmetrically designed. The inner side of the movable sleeve 201 is slidably connected to the outer wall of the slide rod 204. The top of the fixed plate 209 is fixedly connected to the bottom left and right sides of the support bar 1. A controller 8 is fixedly connected to the middle of the top surface of the front support bar 1. The controller 8 is electrically connected to the telescopic rod 3 and the cylinder 203 respectively.

[0036] Specifically, these protective plates 7 effectively prevent external objects from impacting the U-shaped bracket 6, thereby extending the service life of the entire device. The protective plates 7 are usually made of wear-resistant material to ensure that they can maintain good protective effect for a long time. The controller 8, as the main component of the entire device, is responsible for receiving operating commands and controlling the movement of the telescopic rod 3 and the cylinder 203. The sliding connection between the moving sleeve 201 and the slide rod 204 realizes smooth lifting and lowering operations. The fixed plate 209 provides solid support for the entire structure.

[0037] Working principle: When the container needs to be supported, the container is first moved to the surface of the arc plate 10 and the arc plate 2 12. The container is then supported by the U-shaped bracket 6 and the L-shaped connecting plate 13. The L-shaped connecting plate 2 14 is then fixedly connected to the bottom of the U-shaped bracket 6. The support bar 1 is fixed on the U-shaped bracket 6. At this time, the telescopic rod 3 fixedly connected to the support bar 1 is activated. The arc rod 5 is pulled down through the U-shaped plate 4 and then the anti-slip strip 2 11 fits against the outer wall of the container to provide support and limit the movement. Therefore, it can effectively ensure that the container does not move during the support process and improve the practicality of the support frame.

[0038] After fixing the base plate 202 to the support plate 205, the cylinder 203 rotatably connected to the rotating plate 211 is opened, thereby pulling the movable sleeve 201 connected to the rotating plate 212 to slide along the outer wall of the slide rod 204. As the rotating plate 212 moves, it drives the rotating inclined plate 213 and the rotating inclined plate 214 to move to the left, so that the rotating inclined plate 214 slowly becomes vertical. Then, the lifting plate 210 and the fixed plate 209 are moved upward, thereby adjusting the height of the container support frame. This makes it easier for operators to use the container and improves the effectiveness of the support frame.

[0039] 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.
