Description

Technical Field

[0001] The utility model belongs to the technical field of gas cylinder detection, and in particular relates to a gas cylinder bracket suitable for gas cylinder detection. Background Art

[0002] Gas cylinders are generally used to store compressed gas. In order to ensure that there is no leakage and that the cylinders are safe to use, they need to be tested for air tightness and flaw detection before they are officially put into use. When performing flaw detection on gas cylinders, the cylinders need to be rotated continuously so that the detection probe can fully perform flaw detection on the cylinders.

[0003] The existing gas cylinder bracket for gas cylinder inspection cannot conveniently rotate the gas cylinder, and the inspector needs to hold the probe and rotate it along the circumferential direction of the gas cylinder. The inspector also needs to rotate it along the circumferential direction of the gas cylinder, which makes it very inconvenient to perform flaw detection on the gas cylinder. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN212005176U, which limits the position of the gas cylinder from the bottom of the gas cylinder through a cylindrical groove when in use, so that the gas cylinder may tilt when placed and when the gas cylinder is rotated, and then the rotation axis of the gas cylinder does not coincide with its own axis. At this time, the gas cylinder will shake when it rotates, resulting in a continuous change in the distance between the flaw detection equipment and the gas cylinder, making the flaw detection result inaccurate. Utility Model Content

[0004] The utility model aims to provide a gas cylinder bracket suitable for gas cylinder detection, aiming to solve the technical problem in the prior art that the rotation axis of the gas cylinder cannot be guaranteed to coincide with its own axis, resulting in shaking of the gas cylinder during detection.

[0005] The utility model is implemented as follows: a gas cylinder bracket suitable for gas cylinder detection includes a shell, a lifting plate is arranged in the shell, and a first telescopic member for driving the lifting plate to move is fixedly installed in the shell, a supporting roller for supporting the gas cylinder is arranged on the lifting plate, and the shell is provided with limit components located at both ends of the supporting roller for limiting the position of the gas cylinder.

[0006] Further technical solution: the support rollers are provided in multiple groups and distributed in two rows, the two rows of support rollers are symmetrically distributed and a rotating power part is provided on the shell to drive one group of support rollers to rotate.

[0007] Further technical solution: The limiting assembly includes a mounting frame, which is an L-shaped structure and is fixedly installed on the lifting plate. The vertical section of the mounting frame is slidably installed with a first slide, and the end of the first slide is rotatably installed with a top plate, and the rotation axis of the top plate is located in the symmetry plane of the two rows of support rollers.

[0008] Further technical solution: A second slide with a U-shaped structure is slidably installed on the first slide, the opening of the second slide faces the top plate and positioning rollers are rotatably installed at both ends of the second slide, and the rotation axis of the positioning rollers is perpendicular to the symmetry plane of the two rows of supporting rollers.

[0009] Further technical solution: The limit assembly also includes a guide frame, which is fixedly mounted on the lifting plate and a limit plate is slidably mounted on the guide frame. Balls are rotatably mounted on one end of the limit plate away from the lifting plate, and the balls are symmetrical about the symmetrical planes of the two rows of supporting rollers.

[0010] Further technical solution: A third slide plate is slidably mounted on the horizontal section of the mounting frame, a second telescopic member pointing to the lifting plate is fixedly mounted on the surface of the third slide plate close to the lifting plate, and the second telescopic member drives the main body of the flaw detection equipment to move.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. Since the gas cylinder is in a horizontal position and supported by multiple points, the center of gravity of the gas cylinder is in a stable state, so the gas cylinder can rotate stably, avoiding the gas cylinder shaking when rotating due to the misalignment of the rotation axis of the gas cylinder and its own axis. At this time, the flaw detection equipment can move horizontally along the gas cylinder to perform a comprehensive flaw detection on the gas cylinder. The flaw detection equipment can move stably along a straight line, reducing the shaking or rotation of the flaw detection equipment, and improving the stability of the flaw detection and the accuracy of the flaw detection results.

[0013] 2. The gas cylinder can be fully immersed in water to achieve a comprehensive test of the gas tightness of the gas cylinder. The location of the leak can be determined by rotating the gas cylinder and observing the location where the bubbles emerge. This makes it possible to quickly and conveniently determine the location of the gas cylinder leak, making it convenient for subsequent inspection of the gas cylinder. While testing the gas tightness of the gas cylinder, auxiliary wound detection can be performed on the gas cylinder to ensure the accuracy of the gas cylinder detection.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 3 As shown, a gas cylinder holder suitable for gas cylinder detection provided by the utility model includes a shell 1, a lifting plate 3 is arranged in the shell 1, and a first telescopic member 2 is fixedly installed in the shell 1 for driving the lifting plate 3 to move, and a supporting roller 4 for supporting the gas cylinder is arranged on the lifting plate 3. The supporting rollers 4 are provided with multiple groups and are distributed in two rows. The two rows of supporting rollers 4 are symmetrically distributed and a rotating power member 5 for driving one group of supporting rollers 4 to rotate is arranged on the shell 1. The shell 1 is provided with a limit assembly 17 located at both ends of the supporting rollers 4 for limiting the position of the gas cylinder.

[0021] In actual application of this embodiment, the gas cylinder is placed horizontally on the support roller 4 for support, and the gas cylinder is limited from both ends by the limit assembly 17, so as to avoid axial movement of the gas cylinder when it rotates, and ensure the stability of the gas cylinder during flaw detection. After the gas cylinder is placed, one group of support rollers 4 is driven to rotate by the rotating power member 5. At this time, the gas cylinder can be driven to rotate by the support roller 4. At this time, the gas cylinder can be fully flaw-detected by the flaw detection equipment. Since the gas cylinder is in a horizontal position and is supported by multiple points, the center of gravity of the gas cylinder is in a stable state, and then the gas cylinder can rotate stably, avoiding the gas cylinder shaking when it rotates due to the misalignment of the rotation axis of the gas cylinder and its own axis. At this time, the flaw detection equipment can move horizontally along the gas cylinder to perform a comprehensive flaw detection on the gas cylinder. During flaw detection, the flaw detection equipment can move stably along a straight line, reducing the shaking or rotation of the flaw detection equipment, improving the stability during flaw detection and the accuracy of the flaw detection results. After the flaw detection is completed, add an appropriate amount of clean water to a certain depth into the shell 1. At this time, the first telescopic member 2 drives the lifting plate 3 to move downward so that the gas cylinder is immersed in the clean water as a whole. At this time, observe whether there are bubbles in the water. If no bubbles emerge, it means that the air tightness of the gas cylinder is good. At this time, the first telescopic member 2 is reset and the gas cylinder is replaced to continue flaw detection and air tightness detection. If bubbles are generated in the water, the location of the leak can be determined by rotating the gas cylinder and observing the location where the bubbles emerge, so that the location of the leak in the gas cylinder can be determined quickly and conveniently, realizing auxiliary detection of gas cylinder wounds and ensuring the accuracy of gas cylinder detection.

[0022] In an example of this embodiment, the first telescopic member 2 is a first electric telescopic rod, and of course it can also be other components such as a hydraulic cylinder that can actively change the length. The first electric telescopic rod drives the lifting plate 3 to move, thereby realizing the air tightness detection of the gas cylinder.

[0023] like Figure 1-Figure 3 As shown, a gas cylinder bracket suitable for gas cylinder detection provided by the utility model, the limiting assembly 17 includes a mounting frame 6, the mounting frame 6 is an L-shaped structure and is fixedly installed on the lifting plate 3, the vertical section of the mounting frame 6 is slidably installed with a first slide plate 7, the end of the first slide plate 7 is rotatably installed with a top plate 8, and the rotation axis of the top plate 8 is located in the symmetric plane of the two rows of support rollers 4.

[0024] Specifically, a second slide plate 9 with a U-shaped structure is slidably installed on the first slide plate 7. The second slide plate 9 opens toward the top plate 8 and positioning rollers 10 are rotatably installed at both ends of the second slide plate 9. The rotation axis of the positioning rollers 10 is perpendicular to the symmetry planes of the two rows of supporting rollers 4.

[0025] Specifically, the limiting assembly 17 also includes a guide frame 11, which is fixedly mounted on the lifting plate 3 and on which a limiting plate 12 is slidably mounted. A ball 13 is rotatably mounted on one end of the limiting plate 12 away from the lifting plate 3, and the ball 13 is symmetrical about the symmetric planes of the two rows of supporting rollers 4.

[0026] In actual application of this embodiment, the gas cylinder is placed on the supporting roller 4 for support so that the bottom of the gas cylinder contacts the top plate 8, the height of the first slide plate 7 is adjusted and the second slide plate 9 is pushed to move, so that the upper and lower groups of positioning rollers 10 contact the bottom of the gas cylinder at the same time. At this time, the rotation axis of the top plate 8 and the axis of the gas cylinder are located on the same straight line, the position of the first slide plate 7 is fixed by fixing screws and the second slide plate 9 is moved away from the gas cylinder, and then the position of the limiting plate 12 is adjusted so that the ball 13 contacts the arc structure at the top of the gas cylinder, and then the position of the limiting plate 12 is fixed by fixing screws. At this time, the gas cylinder can be restricted from both ends of the gas cylinder by the top plate 8 and the ball 13, so as to avoid axial movement of the gas cylinder during rotation, thereby ensuring the stability of the gas cylinder during flaw detection.

[0027] like Figure 1 , Figure 2 As shown, a gas cylinder bracket suitable for gas cylinder detection provided by the utility model, a third slide plate 14 is slidably installed on the horizontal section of the mounting frame 6, and a second telescopic member 15 pointing to the lifting plate 3 is fixedly installed on the surface of the third slide plate 14 close to the lifting plate 3, and the second telescopic member 15 drives the flaw detection equipment body 16 to move.

[0028] In actual application of this embodiment, the second telescopic member 15 drives the flaw detection device body 16 to move and bring it close to the gas cylinder, and then rotates the gas cylinder. At the same time, the third slide plate 14 is pushed to drive the flaw detection device body 16 to move horizontally along the gas cylinder to perform a comprehensive flaw detection on the gas cylinder. The flaw detection device body 16 can move stably along a straight line, reducing the shaking or rotation of the flaw detection device body 16, thereby improving the stability during flaw detection and the accuracy of the flaw detection results.

[0029] In an example of this embodiment, the second telescopic member 15 is a second electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The second electric telescopic rod drives the flaw detection equipment body 16 to move up and down.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
