The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention.

As shown in fig. 1 to 4, the detection device suitable for pipelines with different diameters comprises a base 1 provided with a clamping mechanism and a detection mechanism, wherein the clamping mechanism comprises a straight rod 2 connected in the base 1 in a sliding manner, the top end of the straight rod 2 is connected with a tray 28 which slides up and down in the base 1 through a spring 27, a pipeline 11 is horizontally placed on the tray 28, a gear 3 driven by a first motor 31 is arranged in the base 1, a rack 35 which moves horizontally in the base 1 is meshed below the gear 3, a rocker 32 which controls the horizontal movement of the detection mechanism is hinged to the side surface of the rack 35, and a control rod 33 which controls the opening and closing of the clamping mechanism is fixed at one end of the rack 35.

Specifically, the detection mechanism comprises a top rod 4 connected in the base 1 in a sliding manner and a piston block 41 matched with the inner wall of the pipeline 11, a connecting block 43 hinged with the rocker 32 is arranged at one end of the top rod 4, and a sliding block 34 hinged on the side surface of the gear 3 is connected on the rocker 32 in a sliding manner; and one end of the pipeline 11, which is far away from the mandril 4, is provided with a sealing ring 12 fixed on the base 1, and an air pump 13 connected with the pipeline 11 is arranged in the sealing ring 12.

Specifically, the base 1 is provided with a painting detection device 14 parallel to the pipeline 11, and the painting detection device 14 detects the movement speed of the piston block 41 in the pipeline 11 through infrared induction and displays the movement speed on a display screen 42; when the speed of the piston block 41 is abnormal, the painting detection device 14 sprays paint on the corresponding position of the pipeline 11.

Specifically, clamping mechanism still includes two

symmetrical grip blocks

25, 2 top both sides of straight-bar are articulated respectively to have first connecting rod 22, articulate second connecting rod 23 one end on base 1 with first connecting rod 22 is articulated, the other end with grip block 25 is articulated, still articulate respectively on base 1 have one end with grip block 25 articulated third connecting rod 24, third connecting rod 24 with second connecting rod 23 is parallel, be fixed with the grip opening 26 that becomes the scissors mouth on the grip block 25.

Specifically, the bottom end of the straight rod 2 is provided with an inclined block 21 of which two sides are inclined surfaces, and the control rod 33 is provided with a first inclined groove 331 and a second inclined groove 332 at intervals, which are matched with the inclined block 21; when the gear 3 drives the rack 35 to move by a distance equal to the distance between the first chute 331 and the second chute 332, the rocker 32 drives the ram 4 to move back and forth in the pipeline 11; when the swash block 21 is located at the first inclined groove 331 or the second inclined groove 332, the jack 4 does not contact the pipe 11.

When the clamping mechanism starts to work, the inclined block 21 on the clamping mechanism is positioned on the first inclined groove 331, and the clamping mechanism is in an unclamped state. When the pipe 11 is horizontally placed on the tray 28, the first motor 31 is started, the gear 3 rotates to drive the rack 35 to move, the inclined block 21 moves upwards under the action of the first inclined groove 331, and when the inclined block 21 is contacted with the top surface of the control rod 33, the clamping block 25 clamps the pipe 11 until the inclined block 21 descends to be matched with the second inclined groove 332.
