Description

Technical Field

[0001] This utility model relates to the technical field of pressure vessel inspection equipment, specifically a support device for pressure vessel inspection that is easy to assemble and disassemble. Background Technology

[0002] Pressure vessel inspection can be divided into external inspection and internal inspection. External inspection mainly focuses on checking for abnormal phenomena such as cracks, deformation, and leakage on the outer surface of the pressure vessel. Internal inspection mostly uses pressure measuring instruments to verify the strength of the pressure vessel. During pressure vessel inspection, the pressure vessel needs to be stably supported to ensure the smooth progress of the inspection operation.

[0003] Existing pressure vessel inspection methods often employ complex connection structures such as bolt fixing, which require significant time and manpower for disassembly and assembly, severely impacting inspection efficiency. Furthermore, the support stability is insufficient, and some connected devices are prone to loosening and shaking, posing safety hazards to inspection operations. Therefore, it is necessary to design a support device for pressure vessel inspection that is easy to disassemble and assemble to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a support device for pressure vessel inspection that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a support device for pressure vessel inspection that is easy to disassemble and assemble, comprising a telescopic sleeve plate and a container body, wherein a quick-release connector is fixedly installed at the top middle of the telescopic sleeve plate, the quick-release connector has a groove inside, and two ends of the groove are slidably connected to locking blocks, a support plate is provided at the middle of the groove, and a first spring is fixedly connected between the support plate and the locking blocks. A positioning tube is installed at the bottom center of the container body, and slots are opened on both sides of the positioning tube. A stabilizing component is provided between the telescopic sleeve and the container body. A lifting component is installed at the bottom of the telescopic sleeve to push the telescopic sleeve to expand or retract.

[0006] Preferably, the stabilizing component includes support columns, sleeves, and springs. The three sets of support columns are respectively annularly installed on the top of the telescopic sleeve plate, and the three sets of sleeves are respectively annularly installed on the bottom of the container body with the support columns and sleeves corresponding to each other. One end of each of the three sets of springs is fixedly connected to the top of the inside of each set of sleeves.

[0007] Preferably, a compression plate is fixedly connected to one end of the bottom of each set of springs, and the compression plate slides along the inner wall of the sleeve.

[0008] Preferably, the lifting assembly includes a positive and negative lead screw, a movable seat, and a connecting member. The positive and negative lead screw is connected to the bottom of the telescopic sleeve through a coupling. The two sets of movable seats are respectively threaded to the two outer ends of the positive and negative lead screw. The connecting member is connected to the outer side of the two sets of movable seats and the top of the telescopic sleeve through a bearing.

[0009] Preferably, the connector includes a support block and a connecting plate. Two sets of support blocks are fixedly installed on the inner top of the telescopic sleeve plate, and four sets of connecting plates are respectively supported by bearings between the two sets of movable seats and the outer sides of the support blocks.

[0010] Preferably, a handle is installed on the outer side of the telescopic sleeve at the bottom, and rotating the handle drives the forward and reverse lead screws to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By inserting the positioning tube at the bottom of the container body into the groove of the quick-release connector at the top of the telescopic sleeve, the positioning tube squeezes the locking block during insertion, compressing the first spring. When the slot on the positioning tube aligns with the locking block, the first spring rebounds, pushing the locking block into the slot, thus completing the quick installation of the container body. At the same time, a stabilizing component is provided between the telescopic sleeve and the container body to enhance the stability of the connection. When disassembling, the container body can be removed by releasing the locking block from the top of the positioning tube, achieving quick disassembly and assembly. A lifting component is installed at the bottom inside the telescopic sleeve to push the telescopic sleeve to expand or retract, increasing the height of the container body.

[0012] 2. The support column at the top of the telescopic sleeve is inserted into the sleeve at the bottom of the container body, and the spring inside the sleeve is squeezed. The spring force is used to further enhance the stability of the connection and prevent the container body from shaking during inspection. The positive and negative screws rotate. Since the two sets of moving seats are threaded to the two ends of the positive and negative screws respectively, and the threads at the two ends of the screws turn in opposite directions, the rotation of the positive and negative screws will drive the two sets of moving seats to move closer or further apart. The moving seats push the support block through the connecting plate, thereby expanding or retracting the telescopic sleeve and adjusting the height of the telescopic sleeve.

[0015] 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.

[0016] Example 1 Please refer to Figure 1-6 As shown, this utility model provides a support device for pressure vessel inspection that is easy to disassemble and assemble, including a telescopic sleeve plate 1 and a container body 2. A quick-release connector 3 is fixedly installed at the top middle of the telescopic sleeve plate 1. A groove 4 is opened inside the quick-release connector 3. The two ends of the groove 4 are respectively slidably connected to the locking blocks 5. A support plate 6 is provided at the middle of the groove 4. A first spring 7 is fixedly connected between the support plate 6 and the locking blocks 5. A positioning tube 8 is installed at the bottom center of the container body 2. The positioning tube 8 has slots 9 on both sides. A stabilizing component is provided between the telescopic sleeve 1 and the container body 2. A lifting component is installed at the bottom of the telescopic sleeve 1 to push the telescopic sleeve 1 to expand or retract.

[0017] Specifically, by inserting the positioning tube 8 at the bottom of the container body 2 into the groove 4 of the quick-release connector 3 at the top of the telescopic sleeve 1, the positioning tube 8 presses against the locking block 5 during the insertion process, causing the first spring 7 to compress. When the locking groove 9 on the positioning tube 8 aligns with the locking block 5, the first spring 7 rebounds, pushing the locking block 5 into the locking groove 9, thus completing the quick installation of the container body 2. At the same time, a stabilizing component is provided between the telescopic sleeve 1 and the container body 2 to enhance the stability of the connection. When disassembling, the container body 2 can be removed by releasing the locking block 5 from the top of the positioning tube 8, achieving quick disassembly and assembly. A lifting component is installed at the bottom of the telescopic sleeve 1 to push the telescopic sleeve 1 to expand or retract, increasing the height of the container body 2.

[0018] The stabilizing components include support columns 10, sleeves 11, and springs 12. Three sets of support columns 10 are respectively annularly installed on the top of the telescopic sleeve plate 1, and three sets of sleeves 11 are respectively annularly installed on the bottom of the container body 2 with the support columns 10 and sleeves 11 corresponding to each other. One end of each set of springs 12 is fixedly connected to the top of the inside of each set of sleeves 11. The support columns 10 at the top of the telescopic sleeve plate 1 are inserted into the sleeves 11 at the bottom of the container body 2 and squeeze the springs 12 inside the sleeves 11. The elastic force of the springs 12 is used to further enhance the stability of the connection and prevent the container body 2 from shaking during the inspection process.

[0019] Wherein: Each set of springs 12 has a compression plate 13 fixedly connected to one end of its bottom. The compression plate 13 slides along the inner wall of the sleeve 11. Through the compression plate 13 connected to one end of the spring 12, the support column 10 abuts against the compression plate 13, so that the compression plate 13 moves in the sleeve 11 and compresses the spring 12.

[0020] The lifting assembly includes a positive and negative lead screw 14, a movable seat 15, and a connecting member. The positive and negative lead screw 14 is connected to the bottom of the telescopic sleeve 1 via a coupling. The two movable seats 15 are respectively threaded to the two outer ends of the positive and negative lead screw 14. The connecting member is connected to the outer side of the two movable seats 15 and the top of the telescopic sleeve 1 via a bearing. When the positive and negative lead screw 14 rotates, the two movable seats 15 will move closer or further away from each other because the two movable seats 15 are respectively threaded to the two ends of the positive and negative lead screw 14. The threads at the two ends of the lead screw rotate in opposite directions. This rotation will cause the two movable seats 15 to move closer or further away from each other. In turn, the movable seats 15 push the connecting member, which in turn pushes the telescopic sleeve 1 to expand or retract.

[0021] The connector includes a support block 16 and a connecting plate 17. Two sets of support blocks 16 are fixedly installed on the inner top of the telescopic sleeve 1. Four sets of connecting plates 17 are respectively supported by bearings between the two sets of movable seats 15 and the outer side of the support block 16. When the positive and negative screws 14 are rotated, the two sets of movable seats 15 will move closer or further away from each other. The movable seats 15 push the support blocks 16 through the connecting plates 17, thereby expanding or retracting the telescopic sleeve 1 and adjusting the height of the telescopic sleeve 1.

[0022] Among them, a handle 18 is installed on the outer side of the lowest telescopic sleeve plate 1. Rotating the handle 18 drives the positive and negative lead screws 14 to rotate. By rotating the handle 18, the positive and negative lead screws 14 are rotated, so that the two sets of moving seats 15 move outside the positive and negative lead screws 14.

[0023] Working Principle: This utility model provides a support device for pressure vessel inspection that is easy to assemble and disassemble. During use, the positioning tube 8 at the bottom of the container body 2 is inserted into the groove 4 of the quick-release connector 3 at the top of the telescopic sleeve 1. During insertion, the positioning tube 8 presses against the locking block 5, compressing the first spring 7. When the locking groove 9 on the positioning tube 8 aligns with the locking block 5, the first spring 7 rebounds, pushing the locking block 5 into the locking groove 9, completing the quick installation of the container body 2. Simultaneously, the support column 10 at the top of the telescopic sleeve 1 is inserted into the sleeve 11 at the bottom of the container body 2, compressing the spring 12 inside the sleeve 11. The elastic force of the spring 12 further enhances the stability of the connection, preventing… During the inspection process, the container body 2 shakes. Rotating the handle 18 causes the positive and negative lead screws 14 to rotate. Since the two sets of moving seats 15 are threaded to the two ends of the positive and negative lead screws 14 respectively, and the threads at both ends of the lead screws rotate in opposite directions, the rotation of the positive and negative lead screws 14 will cause the two sets of moving seats 15 to move closer or further apart. The moving seats 15 push the support block 16 through the connecting plate 17, thereby causing the telescopic sleeve 1 to expand or retract. The height of the telescopic sleeve 1 can be adjusted according to practical needs. When disassembling, the container body 2 can be removed by releasing the locking block 5 from the top of the positioning tube 8, thus achieving quick disassembly and assembly. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0024] Although the present invention 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 invention should be included within the protection scope of the present invention.
