Description

Technical Field

[0001] The utility model relates to the technical field of special equipment inspection, in particular to a special equipment inspection and detection device. Background Art

[0002] The special equipment inspection and detection device is used to evaluate the structural strength, durability and safety performance of equipment, such as pressure vessels, boilers, cranes, etc. Through the detection device, potential defects, cracks or wear in the equipment can be found to ensure that no dangerous accidents occur under normal working conditions. The device can conduct various performance tests, such as pressure tests, load tests, working ability tests, etc., to verify the working ability and safety of special equipment under the design load. Regularly using the inspection and detection device to detect and evaluate the equipment can detect potential problems of the equipment in advance and take preventive maintenance measures to extend the service life and reliability of the equipment.

[0003] The clamping device is used to stabilize and fix the equipment or detection tool to be inspected to ensure the stable position of the equipment during the test without movement. Usually, the clamping force is controlled by a mechanical handle or a pneumatic / hydraulic device, so that the equipment to be detected can maintain a fixed position during the test and is not affected by external interference. The support structure provides stable support and fixation for the entire detection device, enabling it to remain stationary during the test. The structural design should be able to withstand the weight of the equipment and the forces generated by the movement to ensure the stability and safety of the device during operation. The guiding mechanism is used to guide and position the moving part of the detection device to ensure its stability and accuracy during movement. By optimizing the design of the guiding structure, the friction and vibration during movement can be reduced, and the positioning accuracy and movement smoothness of the device can be improved.

[0004] The pressure pipeline in special equipment refers to all pipelines that need to bear internal or external pressure. Due to its wide range of applications, after production, professional detection equipment is required to conduct a detailed inspection of the pressure pipeline. However, the current detection devices on the market generally have the limitation that they cannot directly detect the internal situation of the pressure pipeline, which often requires multiple repeated detections to minimize the error range of the detection results, thus leading to a reduction in the overall work efficiency. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a special equipment inspection and detection device, aiming to improve the problem that the traditional device cannot detect deep inside the pressure pipeline, resulting in inaccurate results.

[0006] To achieve the above object, the utility model adopts the following technical solutions: A special equipment inspection and testing device, including a machine body, a first motor is fixedly connected to the top of the machine body, a first bevel gear is fixedly connected to the output end of the first motor, a second bevel gear is rotatably connected to the top of the machine body, the outer walls of the first bevel gear and the second bevel gear are meshed with each other, a driven gear is fixedly connected to the side wall of the second bevel gear, a slider is fixedly connected to the top of the machine body, a connecting block is fixedly connected to the side wall of the slider, a rack is fixedly connected to the inside of the connecting block, the rack is meshed with the outer wall of the driven gear, a plurality of turntables are fixedly connected to the side wall of the first bevel gear, a belt is arranged between two turntables, a moving column is fixedly connected to the inside of the turntable, a sliding column is fixedly connected to one end of the moving column, a sliding groove is formed in the outer wall of the sliding column, a limiting column is fixedly connected to the side wall, and the limiting column is slidably connected to the inside of the sliding groove.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 6 , an embodiment provided by the present invention: A special equipment inspection and testing device, including a body 1, a first motor 2 is fixedly connected to the top of the body 1, a first bevel gear 3 is fixedly connected to the output end of the first motor 2, a second bevel gear 6 is rotatably connected to the top of the body 1, the outer walls of the first bevel gear 3 and the second bevel gear 6 are engaged with each other, a driven gear 11 is fixedly connected to the side wall of the second bevel gear 6, a slide block 8 is fixedly connected to the top of the body 1, a connecting block 13 is fixedly connected to the side wall of the slide block 8, a rack 12 is fixedly connected to the inside of the connecting block 13, the outer walls of the rack 12 and the driven gear 11 are engaged with each other, a plurality of turntables 5 are fixedly connected to the side wall of the first bevel gear 3, a belt 4 is arranged between two turntables 5, a moving column 7 is fixedly connected to the inside of the turntable 5, a slide column 9 is fixedly connected to one end of the moving column 7, a chute 26 is opened on the outer wall of the slide column 9, a positioning column 25 is fixedly connected to the side wall of the 8, and the positioning column 25 is slidably connected to the inside of the chute 26. One end of the slide column 9 is fixedly connected to a test board 10, and a lifting assembly is arranged inside the body 1, and the lifting assembly is used to lift the detection structure.

[0027] Specifically, through the output of the first motor 2, the first bevel gear 3 is driven to rotate. Due to the meshing relationship between the first bevel gear 3 and the second bevel gear 6, the second bevel gear 6 also starts to rotate, thereby driving the rotation of the driven gear 11. In view of the meshing relationship between the driven gear 11 and the rack 12, as the driven gear 11 rotates, the rack 12 starts to move, thereby driving the movement of the slider 8. The movement of the slider 8 is transmitted through the slide post 9 to push the test plate 10 to move. During this process, the two turntables 5 are interconnected through the belt 4. As the first bevel gear 3 rotates, one of the turntables 5 drives the other turntable 5 to rotate through the transmission of the belt 4, thereby further driving the rotation of the connecting rod 7, which in turn drives the rotation of the slide post 9. Since the limit post 25 cooperates with the chute 26 to restrict the movement of the slide post (9), the slide post 9 starts to slide inside the slider 8, thereby pushing the test plate 10 to move, realizing the detection inside the pressure pipeline and improving the accuracy of the detection result.

[0028] Refer to Figure 1 and Figure 4 , the lifting assembly includes a support plate 22, the bottom of the support plate 22 is slidably connected to the top of the machine body 1, a second motor 14 is fixedly connected inside the machine body 1, the output end of the second motor 14 is fixedly connected with a worm 23, a fixed column 21 is fixedly connected inside the support plate 22, the machine body 1 is rotatably connected with a worm gear 24, the worm gear 24 is meshed with the outer wall of the worm 23, a rotating rod 15 is fixedly connected inside the worm gear 24, a plurality of limiting blocks 16 are rotatably connected to the outer wall of the rotating rod 15, a support column 18 is slidably connected inside the fixed column 21, a connecting rod 17 is fixedly connected to the bottom of the support plate 22, one end of the rotating rod 15 is fixedly connected to the connecting rod 17, a limiting column 19 is slidably connected to the outer wall of the support column 18, one end of the connecting rod 17 is rotatably connected inside the limiting block 16, the inner wall of another limiting column 19 is fixedly connected to one end of the support column 18, a spring 20 is sleeved on the outer wall of the support column 18, one end of the spring 20 is fixedly connected to the bottom of one of the limiting columns 19, and the other end of the spring 20 is fixedly connected to one end of the support column 18.

[0029] Specifically, through the output of the second motor 14, the rotating rod 15 is driven to rotate, thereby causing the connecting rod 17 to rotate and adjust its relative position. To ensure the stability of the transformation of the connecting rod 17, due to the existence of the limiting block 16, the transformation process of the connecting rod 17 is effectively stabilized. Subsequently, the rotation of the connecting rod 17 drives the movement of the support plate 22, and the movement of the support plate 22 further causes the fixed column 21 to displace. During this displacement process, the spring 20 and the limiting column 19 work together. The buffering effect of the spring 20 makes the movement of the fixed column 21 smoother, avoiding possible impacts and vibrations, while the other limiting column 19 imposes necessary restrictions on the support plate 22, ensuring the stability and accuracy of the entire lifting process, and the detection device successfully realizes the lifting function.

[0030] Working principle: The output of motor 1 drives bevel gear 1 to rotate. Since bevel gear 1 meshes with bevel gear 2, bevel gear 2 starts to rotate, driving driven gear 11 to rotate. Given that driven gear 11 meshes with rack 12, as driven gear 11 rotates, rack 12 starts to move, driving slider 8 to move, and then driving test plate 10 to move through slide post 9. During this process, the two turntables 5 are connected to each other by belt 4. As bevel gear 1 rotates, one turntable 5 drives the other turntable 5 to rotate through belt 4, driving moving column 7 to rotate. Since limit block 25 cooperates with chute 23, the movement of (9) is restricted, causing slide post 9 to slide inside slider 8, thus pushing test plate 10 to move, realizing the detection inside the pressure pipeline, and improving the accuracy of the detection results. The output of motor 2 drives worm 23 to rotate. Since worm 23 meshes with worm gear 24, worm gear 24 is driven to rotate, and then rotating rod 15 rotates together with worm gear 24, driving connecting rod 17 to rotate and changing the relative position of connecting rod 17. Due to the existence of limit block 16, the transformation of connecting rod 17 is more stable, driving support plate 22 to move, and then driving fixed column 21 to move. During this process, spring 20 cooperates with limit post 19, making the movement of fixed column 21 stable through spring 20, and the other limit post 19 can limit support plate 22, thus completing the lifting of the detection device.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
