Description

Technical Field

[0001] This utility model belongs to the field of pressure vessel technology, and specifically relates to a fixing device for pressure vessel testing. Background Technology

[0002] A pressure vessel is a closed device that can withstand a certain internal or external pressure (usually a gauge pressure greater than or equal to 0.1 MPa). Its internal pressure is significantly different from the external atmospheric pressure. Pressure vessel inspection fixing devices are auxiliary tools specifically used to securely, stably, and accurately fix pressure vessels during non-destructive testing (NDT) or other inspection processes.

[0003] Existing pressure vessel testing fixtures involve placing the pressure vessel to be tested on a platform and then controlling an electric push rod to move a clamping block close to the pressure vessel for stable clamping and fixing. This ensures that the pressure vessel can be stably clamped and fixed during testing. However, in actual use, the clamping direction of the pressure vessel is relatively unidirectional, which may cause the pressure vessel to move under the action of the testing instrument during subsequent testing, potentially affecting the accuracy of the testing. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a fixing device for pressure vessel testing, which can quickly and stably fix the pressure vessel by coordinating the horizontal and vertical directions to prevent the pressure vessel from moving during testing.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a fixing device for pressure vessel testing, including a workbench, a guide rail symmetrically distributed on the upper surface of the workbench, a slide table symmetrically distributed between the guide rails, a lifting seat slidably disposed on each slide table, a clamping seat disposed on each lifting seat via a support rod, a rubber clamping block disposed on the opposite inner side of the clamping seat, and a placement seat symmetrically distributed on the upper surface of the workbench.

[0006] As a further improvement of this utility model, rotating arms are rotatably mounted on the outer side of the clamping base via rotating shafts, and clamping rollers are fixedly mounted in the middle of the rotating arms; rotating rods are rotatably mounted inside the clamping base, and the rotating rods are fixed to adjacent rotating shafts via couplings; worm gears are fixedly sleeved on the outer arc surface of the rotating rods; a worm is rotatably mounted in the middle of the clamping base, and the worm meshes with the worm gear; a servo motor is mounted on the upper surface of the clamping base, and the output shaft of the servo motor is fixed to the adjacent worm via a coupling.

[0007] As a further improvement of this utility model, each slide table is equipped with an electric push rod II, the telescopic ends of which are respectively connected and fixed to the adjacent lifting seats; the upper surface of the worktable is provided with symmetrically distributed electric push rods I, the telescopic ends of which are connected and fixed to the adjacent lifting seats.

[0008] As a further improvement of this utility model, the lower surface of the workbench is provided with multiple support legs, and the front side of the workbench is provided with symmetrically distributed door panels.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the extension and retraction ends of the electric push rod 2 are controlled to drive the sliding between the lifting seat and the slide table connected to it, thereby controlling the operation of the electric push rod 1. This causes the extension and retraction ends of the electric push rod 1 to drive the slide table to slide between the guide rails, so that the rubber clamps on the left and right sides clamp and fix the pressure vessel in the horizontal direction.

[0011] Secondly, the servo motor is controlled to rotate, causing the output shaft of the servo motor to rotate with the adjacent worm gear, which in turn causes the rotating arm to drive the clamping roller to rotate towards the side closer to the pressure vessel. This allows the clamping roller to approach the pressure vessel to be tested and clamp and fix it vertically in a stable manner.

[0012] Thirdly, the cooperation of electric push rod one and electric push rod two allows the rubber clamp to clamp the pressure vessel horizontally at a suitable position, and the servo motor allows the clamping roller to clamp the pressure vessel vertically. The cooperation of the horizontal and vertical directions can quickly and stably fix the pressure vessel and prevent it from moving during testing. Attached Figure Description

Detailed Implementation

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 2 , 4 As shown, the worktable includes a workbench 101. Symmetrically distributed guide rails 104 are provided on the upper surface of the workbench 101. Symmetrically distributed slides 105 are slidably arranged between the guide rails 104. Each slide 105 has a slidably mounted lifting seat 106. Each lifting seat 106 has a clamping seat 108 mounted on a support rod 107. Rubber clamps 109 are provided on the opposite inner surfaces of the clamping seats 108. Symmetrically distributed placement seats 112 are provided on the upper surface of the workbench 101. Each slide 105 has a second electric push rod 202 inside, the telescopic ends of which are connected and fixed to adjacent lifting seats 106. Symmetrically distributed first electric push rods 201 are also provided on the upper surface of the workbench 101, the telescopic ends of which are connected and fixed to adjacent lifting seats 106.

[0021] like Figure 2 , 3 As shown, rotating arms 110 are rotatably mounted on the outer side of the clamping base 108 via rotating shafts, and clamping rollers 111 are fixedly mounted in the middle of the rotating arms 110. Rotating rods 203 are rotatably mounted inside the clamping base 108. The rotating rods 203 are fixed to adjacent rotating shafts via couplings. Worm wheels 204 are fixedly sleeved on the outer arc surface of the rotating rods 203. Worms 205 are rotatably mounted in the middle of the clamping base 108, and the worms 205 are meshed with the worm wheels 204. Servo motors 206 are mounted on the upper surface of the clamping base 108. The output shaft of the servo motors 206 is fixed to the adjacent worms 205 via couplings.

[0022] like Figure 1 , 2As shown, the lower surface of the workbench 101 is provided with multiple support legs 102, and the front side of the workbench 101 is provided with symmetrically distributed door panels 103.

[0023] When in use, the pressure vessel to be tested is placed between the placement seats 112. The extension and retraction ends of the electric push rod 202 are controlled to drive the lifting seat 106 and the slide table 105 connected to it to slide, thereby causing the lifting seat 106 to drive the clamping seat 108 to rise or fall, so that the transverse axis of the clamping seat 108 and the transverse axis of the pressure vessel to be tested are on the same transverse plane.

[0024] Then control the electric push rod 201 to run, so that the telescopic end of the electric push rod 201 drives the slide table 105 to slide between the guide rails 104, so that the slide tables 105 on the left and right sides move closer to each other, and then drive the clamping seats 108 on the left and right sides to move closer to each other, so that the rubber clamping blocks 109 on the left and right sides clamp and fix the pressure vessel in the horizontal direction.

[0025] The servo motor 206 is controlled to run, causing the output shaft of the servo motor 206 to rotate with the adjacent worm 205. Through the meshing relationship between the worm 205 and the worm wheel 204, the rotating rod 203 where the worm wheel 204 is located is driven to rotate, which in turn causes the rotating rod 203 to drive the rotating arm 110 to rotate. The rotating arm 110 then drives the clamping roller 111 to rotate towards the side closer to the pressure vessel, thereby causing the clamping roller 111 to approach the pressure vessel to be tested and clamp and fix it vertically in a stable manner.

[0026] The cooperation of electric push rod 1 201 and electric push rod 202 allows the rubber clamp 109 to clamp the pressure vessel horizontally at a suitable position. The servo motor 206 enables the clamping roller 111 to clamp the pressure vessel vertically. The cooperation of the horizontal and vertical directions can quickly and stably fix the pressure vessel and prevent it from moving during testing.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
