DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Embodiment 1

The horizontal end of the L-shaped rod 4 is provided with a first rack 6, and the L-shaped rod 4 moves freely along the horizontal direction of the slider 3. The slider 3 is provided with a track or a slot, and one end of the L-shaped rod 4 is provided in the track or the slot, and moves freely along the track or the slot. The column 2 is fixedly provided with a first motor 7, and the output shaft of the first motor 7 is fixedly provided with a first gear 8, and the first gear 8 is meshed and connected with the first rack 6; a rack and gear transmission mechanism is provided on the L-shaped rod 4, which is used to control the left and right movement of the L-shaped rod 4, and is used to adjust the distance between the ultrasonic probe 5 and the pressure vessel, so as to meet the requirements of pressure vessel pipeline detection of different sizes. The applicability of the device of the utility model is enhanced, and the pressure vessel pipeline detection efficiency is improved. The base 1 is provided with a rotating mechanism 9, and the rotating mechanism 9 is fixedly provided with a clamping mechanism 10, and the clamping mechanism 10 is provided with a pressure vessel 11. When the pressure vessel 11 is clamped on the clamping mechanism 10, the pressure vessel to be inspected is controlled to rotate along the rotating axis by the rotating mechanism 9, and the ultrasonic probe 5 inspects the outer cylindrical surface of the pressure vessel, thereby achieving full inspection of the outer circumference of the pressure vessel, which is very practical.

[0023] The column 2 is vertically provided with a second rack 12, the slider 3 is provided with a second gear 13, the second gear 13 is meshed and connected with the second rack 12, and the slider 3 is fixedly provided with a second motor 14, the output shaft of the second motor 14 is axially connected with the second gear 13. When the pressure vessel 11 is detected, the second motor 14 drives the second gear 13 to mesh and transmit with the rack, and the slider 3 can be driven to move up and down, so as to perform ultrasonic detection on various positions of the pressure vessel in the vertical direction.

[0024] The rotating mechanism 9 includes a platform 15, a rotating shaft 16, and a driving motor 17. The platform 15 is fixedly connected to the end of the rotating shaft 16. The rotating shaft 16 passes through the base 1. The base 1 is connected to the rotating shaft 16 by a bearing. The driving motor 17 is arranged below the base 1. The other end of the rotating shaft 16 is connected to the driving motor 17 by a coupling. When testing a pressure vessel, by controlling the rotation of the pressure vessel, multiple positions of the pressure vessel can be fully tested.

[0025] The driving motor 17 includes a motor and a reduction mechanism. The driving motor 17 includes a reduction mechanism, which is used to control the pressure vessel to rotate at a low speed, and at the same time has a large torque, thereby improving the safety and reliability of the device of the utility model.

[0026] The clamping mechanism 10 includes an L bracket 18, which is divided into three groups. The three groups of L brackets 18 are evenly distributed on the same arc. A rail platform 19 is arranged below the L bracket 18. A rail groove 20 is arranged on the rotating mechanism 9. The rail platform 19 is slidably connected to the rail groove 20. A push rod 21 is horizontally passed through the upper part of the L bracket 18. The push rod 21 is movably connected to the axial hole of the L bracket 18. A clamp plate 22 is arranged at the end of the push rod 21. A spring 23 is sleeved on the push rod 21. The spring 23 is arranged between the clamp plate 22 and the L bracket 18. A limiting platform is arranged at the end of the push rod 21 opposite to the clamp plate 22. The limiting platform is used to limit the push rod 21 on the L bracket 18, which can move freely. However, due to the action of the limiting platform, the end of the push rod 21 cannot be separated from the bracket 18. In the embodiment of the utility model, the limiting platform can also adopt other similar structures for limiting, such as a cotter pin structure. In the embodiment of the utility model, the clamping mechanism 10 includes three groups of clamping units composed of L brackets 18, which are used to clamp the pressure vessel to be tested. Since the bottom of the pressure vessel is generally an arc structure, when the pressure vessel is placed on the platform, it will cause the pressure vessel to be unstable and easy to tilt, which poses a safety hazard. In the embodiment of the utility model, the pressure vessel 11 is fixedly connected to the platform through the clamping mechanism, which improves the safety and practicality of the utility model. In the embodiment of the utility model, the rail platform 19 can be an inverted V-shaped platform or a T-shaped platform. The rail groove 20 used in conjunction with the rail platform 19 adopts the same structure as the rail platform 19, which is used to limit one end of the L bracket 18 in the rail groove 20 and can slide freely. A spring 23 is provided between the clamping plate 22 and the L bracket 18, which can prevent the pressure plate 22 from damaging the hard connection of the pressure vessel and play a certain buffering and protective role.

[0027] A telescopic mechanism 24 is provided at one end of the rail groove 20, and a free end of the telescopic mechanism 24 is fixedly connected to the end of the L bracket 18. The telescopic mechanism 24 is used to control the forward and backward movement of the L bracket 18. The L bracket 18 moves in the rail groove 20. When the pressure vessel needs to be clamped, the telescopic mechanism 24 is controlled to make the L bracket 18 move toward the pressure vessel. When the pressure vessel does not need to be clamped, the L bracket 18 is controlled to move away from the pressure vessel.

[0028] The clamping plate 22 is an arc-shaped plate, and a rubber pad is arranged on the inner surface of the clamping plate 22 .

[0029] The column 2 is a cylindrical column.

[0030] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
