It includes two semi-circular rings, with a rotating device mounted outside each semi-circular ring. A detection device is fixedly connected to the rotating device. An opening and closing device is installed at the contact surface of the two semi-circular rings, and a fixing device is fixedly connected to the lower part of each semi-circular ring. In this utility model, a roller drives a moving plate to rotate circumferentially along the semi-circular rings, allowing a probe mounted on the moving plate to perform detection along the circumference of the gas cylinder. After the current area is detected, a second motor is started, driving a reciprocating screw to rotate.

Description

Technical Field

[0001] This utility model belongs to the field of defect detection technology, and in particular relates to a defect scanning device for high-pressure gas cylinders. Background Technology

[0002] Currently, the external wall inspection of high-pressure gas cylinders mostly adopts a manual, handheld probe scanning method. This method has problems such as low efficiency, difficulty in controlling the detection path, and uneven coverage. Especially when the cylinder body is cylindrical and curved, manual operation often makes it difficult to maintain a constant fit between the probe and the outer wall of the cylinder, which can easily lead to missed scans or repeated scans, thus affecting the reliability of the test results. At the same time, when changing the test cylinder, most existing detection devices require disassembly or readjustment of the probe position, which is a cumbersome operation process and the fixing method is not convenient enough, affecting the overall detection efficiency.

[0003] Based on this, the present invention designs a defect scanning device for high-pressure gas storage cylinders to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the current problem that the external wall inspection of high-pressure gas cylinders is mostly carried out by manually scanning point by point with a handheld probe. This method has problems such as low efficiency, difficulty in controlling the detection path, and uneven coverage. Therefore, this invention proposes a high-pressure gas cylinder defect scanning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A defect scanning device for high-pressure gas storage cylinders includes two semicircular rings, a rotating device is installed outside the semicircular rings, a detection device is fixedly connected to the rotating device, an opening and closing device is installed on the contact surface of the two semicircular rings, and a fixing device is fixedly connected to the lower part of the semicircular rings.

[0007] The rotating device includes a movable plate and a first motor. The first motor is fixedly connected to the upper surface of the movable plate. Four rotating shafts are rotatably connected inside the movable plate. Rollers are sleeved on the rotating shafts. The four rollers are locked outside the semi-circular ring. The output end of the first motor is fixedly connected to one of the rotating shafts.

[0008] The detection device includes a second motor, and a reciprocating lead screw is installed at the output end of the second motor. A threaded cap is provided on the outer sleeve of the reciprocating lead screw. An electric push rod is fixedly connected to one side of the threaded cap. A mounting rod is fixedly connected to one side of the electric push rod. A probe is fixedly connected to the lower part of the mounting rod.

[0010] The detection device also includes a frame, which is fixedly connected to one side of the moving plate. The second motor is fixedly connected to the upper surface of the frame, and the reciprocating lead screw is rotatably connected inside the frame.

[0011] As a further description of the above technical solution:

[0012] The cross-section of the threaded cap is rectangular, and one side of the rectangle overlaps the frame.

[0013] As a further description of the above technical solution:

[0014] The opening and closing device includes four connecting plates, which are symmetrically installed outside two semicircular plates. Locking plates are installed on the opposite faces of two corresponding connecting plates, and their positions are staggered. Locking rods are provided in the two locking plates.

[0015] As a further description of the above technical solution:

[0016] The fixing device includes two vertical plates, which are respectively connected to the lower surface of the corresponding semicircular rings. Each vertical plate has a threaded rod inside it. One end of the threaded rod is fixedly connected to a handle, and the other end of the threaded rod is rotatably connected to a clamping plate.

[0019] As a further description of the above technical solution:

[0020] The clamping plate is configured as an arc-shaped plate, and an anti-slip pad is provided inside the arc-shaped plate.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0022] 1. In this utility model, by setting up a first motor and a moving plate in cooperation, the first motor drives one of the rotating shafts to rotate, thereby driving the roller to roll outside the semi-circular ring. The roller drives the moving plate to rotate circumferentially along the semi-circular ring, so that the probe mounted on the moving plate can detect along the circumference of the gas storage bottle. After the current area is detected, only the second motor needs to be started. The second motor drives the reciprocating screw to rotate. When the reciprocating screw rotates, it pushes the threaded cap to move axially, thereby moving the probe along the axial direction of the bottle body and changing the detection area. At the same time, the probe can also be adjusted to be near or far by an electric push rod to adapt to different surface conditions of the bottle body, realizing bidirectional scanning of the probe in both the circumferential and axial directions, ensuring complete detection coverage, and making the operation relatively convenient.

[0023] 2. In this utility model, by setting an opening and closing device at the semi-circular ring joint, when the inspection is completed or the gas cylinder needs to be replaced, simply remove the corresponding locking rod to unlock the two locking plates, and the two semi-circular rings can then unfold, facilitating quick and easy release of the fixation. At the same time, the fixing device adopts a cooperative structure of threaded rod and clamping plate. By turning the handle, the threaded rod and the arc-shaped clamping plate can be moved synchronously, thereby achieving clamping or loosening of the outer wall of the gas cylinder. The clamping plate is also equipped with an anti-slip pad, which further improves the stability of the cylinder fixation. Through the above structural design, the operator can complete the clamping and replacement of the cylinder without complicated disassembly, significantly improving the flexibility and work efficiency of the inspection operation.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4 ,

[0032] First embodiment:

[0033] This utility model provides a technical solution: a high-pressure gas cylinder defect scanning device, including two semicircular rings 1, a rotating device 2 installed outside the semicircular rings 1, a detection device 3 fixedly connected outside the rotating device 2, an opening and closing device 4 installed on the contact surface of the two semicircular rings 1, and a fixing device 5 fixedly connected below the semicircular rings 1.

[0034] The rotating device 2 includes a movable plate 201 and a first motor 204. The first motor 204 is fixedly connected to the upper surface of the movable plate 201. Four rotating shafts 202 are rotatably connected inside the movable plate 201. Rollers 203 are sleeved on the rotating shafts 202. The four rollers 203 are locked on the outside of the semi-circular ring 1. The output end of the first motor 204 is fixedly connected to one of the rotating shafts 202. The rollers 203 are sleeved on the rotating shafts 202 and roll on the outer surface of the semi-circular ring 1. The contact between the rollers 203 and the semi-circular ring 1 reduces frictional resistance, making the movable plate 201 rotate more smoothly. This combination can not only achieve stable guidance, but also ensure that the probe 307 has a precise path during circumferential movement and will not deviate.

[0035] The detection device 3 includes a second motor 302. A reciprocating lead screw 303 is installed at the output end of the second motor 302. A threaded cap 304 is sleeved on the reciprocating lead screw 303. An electric push rod 305 is fixedly connected to one side of the threaded cap 304. An installation rod 306 is fixedly connected to one side of the electric push rod 305. A probe 307 is fixedly connected to the lower part of the installation rod 306. One end of the electric push rod 305 is connected to the installation rod 306. When the push rod extends or retracts, it can drive the installation rod 306 and the probe 307 to adjust up and down. Through this cooperation, the probe 307 can be finely adjusted according to the curvature of the outer wall of the bottle or different diameter positions to ensure a higher fit during detection and avoid distortion of the probe 307 due to improper distance.

[0036] Specifically, such as Figures 2-3 As shown, the detection device 3 also includes a frame 301, which is fixedly connected to one side of the moving plate 201. The second motor 302 is fixedly connected to the upper surface of the frame 301. The reciprocating screw 303 is rotatably connected inside the frame 301. The cross-section of the threaded cap 304 is set to be rectangular, and one side of the rectangle overlaps the outside of the frame 301.

[0037] During operation, by cooperating with the first motor 204 and the moving plate 201, the first motor 204 drives one of the rotating shafts 202 to rotate, thereby driving the roller 203 to roll outside the semi-circular ring 1. The roller 203 drives the moving plate 201 to rotate circumferentially along the semi-circular ring 1, so that the probe 307 mounted on the moving plate 201 can perform detection along the circumference of the gas storage bottle. After the current area is detected, the second motor 302 is started. The second motor 302 drives the reciprocating screw 303 to rotate. When the reciprocating screw 303 rotates, it pushes the threaded cap 304 to move axially, thereby moving the probe 307 along the axial direction of the bottle body and changing the detection area. At the same time, the probe 307 can also be adjusted in distance by the electric push rod 305 to adapt to different surface conditions of the bottle body, realizing bidirectional scanning of the probe 307 in both the circumferential and axial directions, ensuring complete detection coverage, and making the operation relatively convenient.

[0038] Second embodiment:

[0039] Specifically, such as Figure 4 As shown, the opening and closing device 4 includes four connecting plates 401, which are symmetrically installed outside the two semicircular plates. Locking plates 402 are installed on the opposite faces of two corresponding connecting plates 401, and their positions are staggered. Locking rods 403 are provided within the two locking plates 402. The fixing device 5 includes two vertical plates 501, which are respectively connected to the lower surface of the corresponding semicircular ring 1. Threaded rods 502 are provided within the vertical plates 501, and a handle 503 is fixedly connected to one end of each threaded rod 502. The other end of 502 is rotatably connected to a clamping plate 504. The vertical plate 501 has an internal thread, and the vertical plate 501 and the threaded rod 502 form a threaded connection. The clamping plate 504 is set as an arc plate, and the arc plate has an anti-slip pad inside. The clamping plate 504 is an arc plate that fits against the outer wall of the gas storage bottle, and the anti-slip pad is set on its inner side, which can effectively increase the friction and prevent the bottle from sliding or shifting during the test. Through the cooperation between these small structures, the bottle is guaranteed to maintain a stable position during the test, and the reliability of the test is improved.

[0040] During operation, by setting an opening and closing device 4 at the joint of the semicircular ring 1, when the inspection is completed or the gas cylinder needs to be replaced, simply remove the corresponding locking rod 403 to unlock the two locking plates 402, and the two semicircular rings 1 can then unfold, making it convenient and quick to release the fixation. At the same time, the fixing device 5 adopts a cooperative structure of threaded rod 502 and clamping plate 504. By turning the handle 503, the threaded rod 502 and the arc-shaped clamping plate 504 can be moved synchronously, thereby achieving the clamping or loosening of the outer wall of the gas cylinder. The clamping plate 504 is also equipped with an anti-slip pad, which further improves the stability of the cylinder fixation. Through the above structural design, the operator can complete the clamping and replacement of the cylinder without complicated disassembly, which significantly improves the flexibility and work efficiency of the inspection operation.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
