[0001] The utility model belongs to the technical field of compression detection, and in particular relates to a compression detection device for a seamless steel pipe. Background Art
[0002] Seamless steel pipe is made by perforating a whole round steel. There is no weld on the surface of the steel pipe, which is called seamless steel pipe. According to the production method, seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-rolled seamless steel pipe, cold-drawn seamless steel pipe, extruded seamless steel pipe, jacking pipe, etc. Seamless steel pipe has a wide range of uses, mainly used as pipes or structural parts for conveying fluids.
[0003] However, the conventional device still has the following problems when used:
[0004] In order to detect the compressive quality of seamless steel pipes during the production process, a pressure testing device for seamless steel pipes is needed. During the testing process, the seamless steel pipes need to be fixed to avoid movement during the pressure test.
[0005] However, when the fixing structure in the prior art is used to fix seamless steel pipes of different specifications, the fixing structure is adjusted according to the size of the seamless steel pipe. Since the size of the fixing plate cannot be adjusted, the fixing plate cannot be completely fitted with the seamless steel pipe when fixed to the seamless steel pipe, thereby reducing the stability effect when fixing the seamless steel pipe.
[0006] Therefore, we need a seamless steel pipe compression testing device to solve the problem that the fixed plate can be adjusted, and the fixed plate can be adjusted. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0026] Embodiment 1
[0027] See also Figures 1 to 5 The utility model provides a technical solution: it includes an operating table 1, a mounting frame 2 is fixedly connected to the top of the operating table 1, a cylinder 3 is fixedly connected to the middle position of the top of the mounting frame 2, the output end of the cylinder 3 passes through the top of the mounting frame 2, an upper pressure block 4 is fixedly connected to the output end of the cylinder 3, a lower pressure block 11 is fixedly connected to the lower part of the mounting frame 2, an arc groove 12 is opened on the opposite side of the lower pressure block 11 and the upper pressure block 4, and a seamless steel pipe is overlapped inside the arc groove 12.
[0028] After placing the seamless steel pipe on the arc groove 12 on the lower pressing block 11, when the radius of the seamless steel pipe is smaller than the radius of the arc groove 12, the fixation of the arc groove 12 to the seamless steel pipe can be weakened. At this time, the height of the fixing groove 5 is adjusted according to the size of the seamless steel pipe. By increasing the height of the fixing groove 5, the contact area between the fixing groove 5 and the seamless steel pipe can be increased, thereby increasing the fixation of the seamless steel pipe. When the seamless steel pipe is fixed, the cylinder 3 on the mounting frame 2 can be started, and then the movement of the cylinder 3 can drive the upper pressing block 4 to press down, thereby testing the pressure resistance of the seamless steel pipe. This equipment not only increases the flexibility of the fixing plate 53, but also improves the fixation effect on the seamless steel pipe.
[0029] Embodiment 2
[0030] A cavity 13 is provided on both sides of the top of the lower pressing block 11 near the arc groove 12, and a fixed groove 5 is slidably connected inside the cavity 13, and a mounting plate 7 is fixedly connected to one side of the fixed groove 5. Strip holes 6 are provided on both sides of the lower pressing block 11, and limiting grooves 9 are provided on both sides of the lower pressing block 11 near the side of the strip hole 6, one side of the limiting groove 9 is connected through one side of the strip hole 6, and a moving rod 8 is slidably connected inside the mounting plate 7, and the outer wall of the moving rod 8 is slidably connected to the inside of the strip hole 6, and the outer wall of the moving rod 8 is movably plugged into the inside of the limiting groove 9, and a handle 10 is fixedly connected to one end of the moving rod 8.
[0031] By moving the handle 10, the movable rod 8 can be moved upward inside the strip hole 6, and then the upward movement of the movable rod 8 can be used to drive the mounting plate 7 to move upward inside the fixed groove 5, so that the fixed groove 5 is moved out from the cavity 13, and one side of the fixed groove 5 can be fixedly connected to the outer wall of the seamless steel pipe, thereby avoiding the movement of the seamless steel pipe in the arc groove 12, and correspondingly increasing the stability of the seamless steel pipe, thereby avoiding the movement of the seamless steel pipe during the compression test, and correspondingly increasing the detection effect of the seamless steel pipe.
[0032] Embodiment 3
[0033] The fixing groove 5 is provided with a cavity 2 51, and a plurality of rubber rings 52 are fixedly connected inside the cavity 2 51, a fixing plate 53 is fixedly connected to one side of the rubber ring 52, and a non-slip elastic pad 54 is fixedly connected to one side of the fixing plate 53, and an outer wall of the fixing plate 53 is slidably connected to the inside of the fixing groove 5, and the fixing plate 53 is divided into a plurality of parts, and one side of the non-slip elastic pad 54 overlaps with one side of the seamless steel pipe.
[0034] After the fixing groove 5 is moved out from the cavity 13, the fixing plate 53 can be driven to move upward. When the fixing plate 53 is completely moved out of the cavity 13, there will be no obstruction on one side of the fixing plate 53, avoiding the cavity 13 to limit the fixing plate 53, and correspondingly increasing the movement effect of the fixing plate 53. At this time, under the action of the rubber ring 52, the fixing plate 53 can be pushed to move, so that one side of the fixing plate 53 is fixed to the outer wall of the seamless steel pipe, avoiding the fixing groove 5 to leave a gap when fixing the seamless steel pipe, thereby weakening the fixing effect of the fixing groove 5, and correspondingly increasing the fixing effect of the fixing groove 5 on the seamless steel pipe, thereby further increasing the stability of the seamless steel pipe.
[0035] The working principle and use process of the utility model are as follows: when in use, firstly, after placing the seamless steel pipe on the arc groove 12 on the lower pressing block 11, when the radius of the seamless steel pipe is smaller than the radius of the arc groove 12, the fixation of the arc groove 12 to the seamless steel pipe can be weakened. At this time, the height of the fixing groove 5 is adjusted according to the size of the seamless steel pipe. By increasing the height of the fixing groove 5, the contact area between the fixing groove 5 and the seamless steel pipe can be increased, thereby increasing the fixation of the seamless steel pipe. At this time, by pulling the handle 10, when the handle 10 is forced to move, the moving rod 8 can be driven to slide to the left inside the mounting plate 7, and then the moving rod 8 can be made to slide out from the limiting groove 9 by the movement of the moving rod 8 to the left, so that the limiting groove 9 on the moving rod 8 can be released. The movable rod 8 is in the position, which prevents the movable rod 8 from moving when it is not working, and correspondingly increases the stability of the movable rod 8. After the movable rod 8 moves from the inside of the limit groove 9 to the inside of the strip hole 6, the handle 10 can be pulled upward, and then the movable rod 8 can be moved upward in the strip hole 6 through the movement of the handle 10. The upward movement of the movable rod 8 can then drive the mounting plate 7 to move upward in the fixed groove 5, so that the fixed groove 5 is moved out of the cavity 13, so that one side of the fixed groove 5 can be fixedly connected to the outer wall of the seamless steel pipe, which prevents the seamless steel pipe from moving in the arc groove 12, and correspondingly increases the stability of the seamless steel pipe, thereby preventing the seamless steel pipe from moving during the compression test, and correspondingly increases the detection effect of the seamless steel pipe.
[0036] After the fixing groove 5 is moved out of the cavity 13, the fixing plate 53 can be driven to move upward. When the fixing plate 53 is completely moved out of the cavity 13, there will be no obstruction on one side of the fixing plate 53, avoiding the cavity 13 to limit the fixing plate 53, and correspondingly increasing the movement effect of the fixing plate 53. At this time, under the action of the rubber ring 52, the fixing plate 53 can be pushed to move, so that one side of the fixing plate 53 is fixed to the outer wall of the seamless steel pipe, avoiding that the fixing groove 5 leaves a gap when fixing the seamless steel pipe, thereby weakening the fixing effect of the fixing groove 5, and correspondingly increasing the fixing effect of the fixing groove 5 on the seamless steel pipe, further increasing the stability of the seamless steel pipe, and then through the provision of the anti-slip elastic pad 54, the poor fixing effect of the fixing plate 53 is avoided, and the fixing effect of the fixing plate 53 is correspondingly improved, and the stability of the seamless steel pipe is further increased.
[0037] When the seamless steel pipe is fixed, the cylinder 3 on the mounting frame 2 can be started, and the movement of the cylinder 3 can drive the upper pressure block 4 to press down, so that the pressure resistance of the seamless steel pipe can be tested. This equipment not only increases the flexibility of the fixing plate 53, but also improves the fixing effect of the seamless steel pipe.
[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
