In summary, when the apparatus uses the richter scale to detect the hardness of the pipeline, the first clamping plate 10 and the second clamping plate 11 are firstly placed on two sides of the pipeline, the first nut pair 8 and the second nut pair 9 are driven to move oppositely by rotating the two-way screw 7 until the first clamping plate 10 and the second clamping plate 11 clamp the pipeline, during the process, the first nut pair 8 drives the first hinge arm 12 to move, the second nut pair 9 drives the second hinge arm 13 to move, the first hinge arm 12 and the second hinge arm 13 drive the fixed shaft 6 and the guide plate 5 to move together, and the guide plate 5 moves linearly and stably under the guiding action of the first guide sleeve 4; during the process, the center of the fixed shaft 6 is always positioned on the symmetrical reference surfaces of the first nut pair 8 and the second nut pair 9, namely the symmetrical reference surfaces of the first clamping plate 10 and the second clamping plate 11, after the pipeline is clamped by the first clamping plate 10 and the second clamping plate 11, the centers of the first guide sleeve 4, the guide plate 5, the fixed shaft 6 and the Richter hardness tester body 2 are all positioned on the reference surface where the center of the pipeline is positioned, and the detection end of the Richter hardness tester body 2 is perpendicular to the end surface of the pipeline; through adjusting the position of first guide bar 15 in second uide bushing 14 for the sense terminal and the contact of pipeline top of the richter durometer body 2, but this moment operation richter durometer body 2 makes its sense terminal strike the surface that awaits measuring with the vertical direction, guarantees the straightness that hangs down of richter durometer, improves and measures the precision.

In a specific embodiment, in order to adjust the position of the first guide rod 15 in the second guide sleeve 14, so that the detection end of the richter hardness tester 2 is stably contacted with the top end of the pipeline, and the hardness of the pipeline can be detected through subsequent operation, a tightening handle 16 for pressing the first guide rod 15 is screwed on the second guide sleeve 14. Second uide bushing 14 radially is equipped with the tight screw hole of deciding handle 16 of installation, through operation adjustment handle, can compress tightly first guide bar 15 regulation in second uide bushing 14 for 15 rigidity of first guide bar, thereby make 2 rigidity of richter scale sclerometer body, rock from top to bottom when avoiding detecting, improve the detection precision.

In a specific embodiment, in order to facilitate the driving of the bidirectional screw 7 in rotation and thus the clamping of the pipe, an adjustment knob 17 is mounted at one end of the bidirectional screw 7. The bidirectional screw 7 can be driven to rotate by rotating the adjusting rotary handle 17.

In a specific embodiment, to prevent the first guide rod 15 from being separated from the second guide sleeve 14, a stopper 18 is fixed on the top of the first guide rod 15, and the stopper 18 restricts the first guide rod 15 from being separated from the second guide sleeve 14. The size of the stopper 18 is larger than the inner diameter of the second guide sleeve 14, so that the first guide rod 15 is prevented from falling from the second guide sleeve 14.

In a specific embodiment, in order to improve the clamping stability, anti-slip teeth 19 are provided on the facing end surfaces of the first clamping plate 10 and the second clamping plate 11. The anti-skidding teeth 19 can increase the contact surface with the pipeline when the first clamping plate 10 and the second clamping plate 11 clamp the pipeline, so that the anti-skidding effect is achieved, the clamping force is improved, the clamping effect is improved, and the stable clamping of the pipeline by the first clamping plate 10 and the second clamping plate 11 is ensured.

In a specific embodiment, in order to enable the bidirectional screw 7 to drive the first nut pair 8 and the second nut pair 9 to stably move in a straight line, a second guide rod 20 is fixed on the frame 3, the second guide rod 20 penetrates through the first nut pair 8 and the second nut pair 9, and the second guide rod 20 is connected with the first nut pair 8 and the second nut pair 9 in a sliding mode. The second guide rod 20 plays a role in guiding, and can prevent the first nut pair 8 and the second nut pair 9 from rotating along with the bidirectional screw 7, so that the first nut pair 8 and the second nut pair 9 can stably convert the rotary motion of the bidirectional screw 7 into linear motion and stably move.

In a specific embodiment, in order to prevent the mounting base 1 from rotating relative to the guide plate 5 and prevent the richter durometer body 2 from deviating from the center of the end face of the pipeline to be detected, the cross section of the first guide rod 15 is rectangular, and the cross section of the inner cavity of the second guide sleeve 14 is matched with the cross section of the first guide rod 15. Thus, the first guide rod 15 does not rotate in the second guide sleeve 14, but moves linearly only under the guiding action of the second guide sleeve 14.

In a specific embodiment, the first guide sleeve 4, the guide plate 5, the fixed shaft 6 and the center of the richter hardness tester body 2 are all arranged on a central reference plane, and the first nut pair 8 and the second nut pair 9 are symmetrically arranged on two sides of the central reference plane. So, after first grip block 10 and the 11 centre gripping pipelines of second grip block, the pipeline center is located this central reference plane promptly, but the measuring end of the Leeb hardness tester body 2 strikes the pipeline top perpendicularly, keeps detecting the precision.
