Description

Technical Field

[0001] The invention relates to a track for detecting a high-pressure gas cylinder and a high-pressure gas cylinder detection device, belonging to the technical field of high-pressure gas cylinder detection. Background Art

[0002] Over the past two or three decades, with the rapid development of my country's national economy, the demand for energy resources has been growing, and at the same time, a large number of petrochemical companies have been developed. These petrochemical industries need a large number of high-pressure gas cylinders for the storage and transportation of raw materials. The safety of these high-pressure gas cylinders is of vital importance. In particular, high-pressure gas cylinders are prone to metal fatigue during the long-term process of pressurizing and transmitting gas and unloading gas, and many high-pressure gas cylinders are placed on the ground, and there are no protective facilities such as underground facilities around them. If there are small cracks or corrosion inside the high-pressure gas cylinder, stress concentration will occur during the pressurization and depressurization process, which will further expand the cracks and may eventually cause an accident.

[0003] In order to avoid cracks in high-pressure gas cylinders that may cause accidents during their use, it is necessary to frequently inspect the high-pressure gas cylinders. For example, the Chinese invention patent application publication document with application publication number CN112014465A discloses an ultrasonic detection device and detection method for in-service pipelines or pressure vessels, which includes a track assembly, a detection trolley, a longitudinal drive assembly and a detection controller, the track assembly includes a flexible track and an auxiliary positioning member for positioning the flexible track on the wall to be detected; the detection trolley includes a trolley body, a transverse drive assembly and a phased array detection probe assembly, the phased array detection probe assembly is fixed to the trolley body, the trolley body is placed on the flexible track, and moves along the flexible track under the drive of the transverse drive assembly; the longitudinal drive assembly is connected to the flexible track to drive the flexible track to move along the wall to be detected; the detection controller includes a probe excitation unit connected to the phased array probe in the phased array detection probe assembly, and a movement control unit connected to the longitudinal drive assembly and the transverse drive assembly. The length of the track assembly of the detection device of this structure is specific. When testing the high-pressure gas cylinder, the track assembly is fixed on the high-pressure gas cylinder to be tested. The track assembly cannot surround the high-pressure gas cylinder. Therefore, each time the track assembly is fixed, only half a circle or even less of the high-pressure gas cylinder can be tested. Therefore, it is necessary to frequently move and fix the track assembly, which makes its detection efficiency relatively low, and it is also more laborious to move and fix the track assembly. Summary of the invention

[0004] The purpose of the present invention is to provide a track for high-pressure gas cylinder detection, so as to solve the technical defect of low detection efficiency of high-pressure gas cylinder detection in the prior art because only half a circle can be detected each time.

[0005] In order to solve the above problems, the technical solution adopted by the present invention is: a track for high-pressure gas cylinder detection is used to cooperate with the first roller on the detection device when detecting the high-pressure gas cylinder to make the detection device move one circle along the high-pressure gas cylinder to be detected. The track for high-pressure gas cylinder detection includes more than two arc-shaped track units, and the track units are connected end to end to form a circular ring, which is used to be mounted on the high-pressure gas cylinder to be detected when in use. Two adjacent track units are detachably provided with connecting parts for connecting the two track units. The track units are provided with track groove units, and the track groove units on all the track units are connected to form a circular track groove, which is used to cooperate with the first roller on the detection device when detecting the high-pressure gas cylinder to make the first roller on the detection device roll in the track groove. The track in the present invention circles around the high-pressure gas cylinder to be tested. When in use, the detection device can move around the track on the high-pressure gas cylinder to be tested. The track is installed on the high-pressure gas cylinder once, and the detection device can detect the high-pressure gas cylinder for one circle. Compared with the prior art, each time the track is installed, only half a circle of the high-pressure gas cylinder can be detected. The present invention reduces the time for installing the track on the high-pressure gas cylinder to be tested, improves the detection efficiency of the high-pressure gas cylinder, and the installation of the present invention on the high-pressure gas cylinder is more convenient than the prior art. The present invention can select an appropriate number of track units according to the diameter of the high-pressure gas cylinder to be tested, so that the present invention is suitable for the detection of high-pressure gas cylinders with different diameters, thereby improving the versatility of the present invention.

[0006] As a further improvement of the present invention, the track unit includes an inner track unit and an outer track unit, the inner track unit is used to be sleeved on the high-pressure gas storage cylinder when in use, a track slot unit is provided on one side or both sides of the inner track unit and / or the outer track unit, the outer track unit is detachably mounted on the inner track unit, and the connector is detachably connected to the outer track unit. The track unit in the present invention is composed of a partially detachable installation, which facilitates the manufacture of the track slot unit, thereby facilitating the manufacture of the track unit as a whole, and the connector is only connected to the outer track unit, which facilitates the connection of the entire track.

[0007] As a further improvement of the present invention, slide rails are provided on both sides of the outer rail unit away from the inner rail unit, and slide grooves matching the slide rails are provided on both sides of the connecting piece. A limiting member is provided on the outer rail unit to prevent the connecting piece from continuing to slide relative to the outer rail unit when one end of the slide rail slides from one end of the slide groove into the slide groove. The present invention facilitates the connection of the connecting piece to the outer rail unit by matching the slide rail with the slide groove, and the setting of the limiting member facilitates the relative fixation of the connecting piece and the outer rail unit after connection.

[0008] As a further improvement of the present invention, a limit cavity is provided on the outer track unit, and the limit piece includes a limit piece body and a limit spring. The limit piece body is arranged in the limit cavity and can slide radially along the track in the limit cavity. A pressing protrusion and two limit protrusions are provided on the side of the limit piece body away from the inner track unit, and the two limit protrusions are respectively located on both sides of the pressing protrusion. The two ends of the limit spring respectively abut against the inner track unit and the limit piece body, and extend or contract as the limit piece body slides in the limit cavity. In the use state, the two ends of the connecting piece are respectively provided with a groove matching with the limit protrusion on the side facing the inner track unit. When the limit piece body slides into the limit cavity, the limit protrusion is driven to disengage from the groove, and the connecting piece can slide relative to the outer track unit. The limit spring extends to push the limit piece body to slide in the direction away from the inner track unit so that the limit protrusion matches with the groove, thereby preventing the connecting piece from sliding relative to the outer track unit. The limit spring in the present invention contracts as the limit piece moves into the limit cavity, which is convenient for the limit piece to be reset in the limit cavity after the limit piece is released. The pressing protrusion is convenient for the connection piece to be limited when sliding on the outer track unit. When the end of the connection piece abuts against the pressing protrusion, the connection piece slides to a desired position relative to the outer track unit. The limit protrusion cooperates with the groove to be fixed to the outer track unit when the connection piece slides to an appropriate position. The present invention realizes the fixing and separation of the connection piece and the outer track unit by sliding the limit piece in the limit groove.

[0009] As a further improvement of the present invention, at least one guide groove is provided on each side of the limit cavity, and guide blocks matching the guide groove are provided on both sides of the limit member body, and when the limit member moves in the limit cavity, the guide blocks slide in the guide groove along the length direction of the guide groove. The present invention limits the movement of the limit member body in the limit cavity by matching the guide groove with the guide block, ensuring that the limit member body slides radially along the track and does not swing in the limit groove.

[0010] As a further improvement of the present invention, a through groove is provided on one side of the middle of the connector away from the inner track unit, and a plurality of reinforcing ribs are provided at intervals in the through groove, and the height of the reinforcing ribs is less than the depth of the through groove. The present invention provides the through groove to enhance the flexibility of the connector, and when the diameter of the high-pressure gas cylinder to be detected is large, the connector can be slightly deformed to make the track unit contact with the surface of the high-pressure gas cylinder.

[0011] As a further improvement of the present invention, a distance adjustment structure is further included, which is used to connect any two track units and adjust the distance between the two track units according to the diameter of the high-pressure gas cylinder to be detected. The present invention is provided with a distance adjustment structure to achieve connection between the track units when the diameter of the high-pressure gas cylinder to be detected is not enough to add another track unit.

[0012] As a further improvement of the present invention, a second roller is rotatably provided on one side of the inner track unit close to the high-pressure gas cylinder. The second roller abuts against the outer surface of the high-pressure gas cylinder when in use. When the track unit moves along the axial direction of the high-pressure gas cylinder on the high-pressure gas cylinder, the second roller rolls on the outer surface of the high-pressure gas cylinder to be detected. In the present invention, a second roller is provided on the inner track unit, which is used to cooperate with the outer surface of the high-pressure gas cylinder to be detected when in use, so that the track can move on the high-pressure gas cylinder to be detected. After the detection device detects one circle, the detection device can be moved to the undetected part by moving the track on the high-pressure gas cylinder to be detected. The detection of the entire high-pressure gas cylinder to be detected can be completed by installing the track once, further improving the detection efficiency of the high-pressure gas cylinder.

[0013] As a further improvement of the present invention, a track drive motor is provided on part or all of the inner track units, and the track drive motor is connected to the rotating shaft of the second roller to drive the second roller to rotate relative to the inner track unit. The present invention is provided with a track drive motor, and the track drive motor drives the second roller to rotate, so that the track moves on the high-pressure gas storage cylinder to be inspected, thereby reducing the manpower input in the track movement.

[0014] Another object of the present invention is to provide a high-pressure gas cylinder detection device, comprising a detection bracket, a detection mechanism, a detection drive motor, a bracket drive motor and two tracks for high-pressure gas cylinder detection, the two tracks for high-pressure gas cylinder detection are used to be set on the high-pressure gas cylinder to be detected, both ends of the detection bracket are provided with a first roller, the first rollers at both ends of the detection bracket are respectively matched with the two track grooves for high-pressure gas cylinder detection, the bracket drive motor drives the first roller to roll in the track groove, the detection mechanism is arranged on the detection bracket and forms a moving pair with the detection bracket, the detection drive motor is used to drive the detection mechanism to reciprocate along the length direction of the detection bracket on the detection bracket, and is used to detect the surface of the high-pressure gas cylinder. In the present invention, the detection drive motor drives the detection mechanism to move between the two tracks to detect the surface of the high-pressure gas cylinder to be detected between the two tracks, the bracket drive motor drives the detection bracket to rotate on the track, and is used to detect different parts of the high-pressure gas cylinder to be detected between the tracks, and through the movement of the track, the detection mechanism completes the overall detection of the high-pressure gas cylinder to be detected.

[0015] The beneficial effects of the present invention are as follows: the detection device in the present invention can move one circle along the track, and detect the high-pressure gas cylinder to be detected for one circle. Compared with the prior art that can only detect half a circle each time, the detection efficiency of the high-pressure gas cylinder is improved, and the track itself in the present invention is movable, and its position on the high-pressure gas cylinder to be detected is adjusted by moving the track. The detection of the high-pressure gas cylinder can be completed by installing the track once, avoiding multiple installations of the track. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] As Fig. 9 shown, the detection bracket in this embodiment includes two mounting blocks 25, two guide rods 26, a connecting rod 27, and a rack 28. The two guide rods 26 and the connecting rod 27 are arranged in parallel. The two guide rods 26 are respectively located on both sides of the connecting rod 27 and in the use state, the two guide rods 26 are closer to the high-pressure gas cylinder to be detected than the connecting rod 27. The two mounting blocks 25 are respectively arranged at both ends of the guide rods 26. The mounting blocks 25 are in a "冂" shape. When in use, the mounting blocks 25 are arranged on the track, and the outer track unit 6 extends into the mounting blocks 25. Both ends of the connecting rod 27 are respectively connected to the two mounting blocks 25. Two first rollers 4 are rotatably mounted on each mounting block 25. The two first rollers 4 face each other. The two first rollers 4 on each mounting block 25 are respectively located in the track grooves on both sides of the track and can roll in the track grooves.

[0045] The number of the bracket drive motors 24 in this embodiment is two. One bracket drive motor 24 is mounted on each mounting block 25, which are respectively used to drive the first rollers 4 on the mounting block 25 where they are located to roll in the track grooves. For the two first rollers 4 on each mounting block 25 in this embodiment, only one of them needs to be driven by the bracket drive motor 24 to rotate.

[0046] The detection mechanism 22 in this embodiment is arranged on the detection bracket 21 and forms a moving pair with the detection bracket 21. The detection drive motor 23 is used to drive the detection mechanism 22 to move back and forth on the detection bracket 21 along the length direction of the detection bracket 21, so as to detect the surface of the high-pressure gas storage cylinder. The rack 28 in this embodiment is detachably mounted on the connecting rod 27 by a plurality of bolts. The detection drive motor 23 is mounted on the detection mechanism 22. A gear 43 is mounted on the output shaft of the detection drive motor 23. The gear 43 is meshed with the rack 28. The detection drive motor 23 drives the gear 43 to rotate. Since the gear 43 is meshed with the rack 28, the detection mechanism 22 is driven to move along the length direction of the rack 28 on the detection bracket 21. In this embodiment, two sliding through holes (not shown in the figure) are preferably provided on the detection mechanism 22, which penetrate the two ends thereof. Two guide rods 26 pass through the two sliding through holes respectively, and the two guide rods 26 guide the sliding of the detection mechanism 22.

[0047] When this embodiment is in use, two tracks are set on the high-pressure gas cylinder to be tested, and the detection drive motor 23 drives the detection mechanism 22 to move from one of the tracks to the other track, and the place where it moves is detected, and then the bracket drive motor 24 drives the mounting block 25 to move on the track, so that the detection mechanism 22 rotates an angle on the high-pressure gas cylinder to be tested, and the detection drive motor 23 drives the detection mechanism 22 to move from one end of the connecting rod 27 to the other end, and the place where the detection mechanism 22 passes is detected. In this way, the mounting block 25 moves around the track once, and the detection of the high-pressure gas cylinder to be tested between the two tracks is completed; the track drive motor 19 drives the second roller 49 to rotate, so that the track moves to an undetected place on the high-pressure gas cylinder to be tested, and the above-mentioned detection action is repeated to complete the detection work of the high-pressure gas cylinder.
