In the research and development process of the anchor cable, it is necessary to study the mechanical properties, deformation properties, failure conditions and other properties of the anchor cable, but it is difficult to measure the movement process of the constant resistance body because the constant resistance body is inside the sleeve.

The power part includes a transmission shaft 4 rotatably connected to the mounting plate 1, a geared disc 5 fixed at both ends of the transmission shaft 4, and a transmission motor 23 mounted on the mounting plate 1 for driving the transmission shaft 4 to rotate. The output shaft of the transmission motor 23 is in transmission connection with the transmission shaft 4. The detection part includes a material fixing mechanism, a transmission mechanism, and a measuring mechanism mounted on the mounting plate 1.

[0048] The material solidifying mechanism includes a mounting plate 1 and a stretching assembly mounted on the outer walls of both sides of the mounting plate 1. The stretching assembly includes a fixed fixture, a movable fixture, and a driving member for driving the movable fixture to move. The fixed fixture includes a fixed cylinder 14 fixed to the mounting plate 1 by a fixed plate, a pressure block 14 arranged in the fixed cylinder 14, a third screw sleeve 30 rotatably connected to the outer periphery of the fixed cylinder 14, and a third screw 36 threadedly sleeved in the third screw sleeve 30. The other end of the third screw 36 extends into the fixed cylinder 14. The locking mechanism 35 is fixed to the locking mechanism 34 by a third screw 36, and the locking mechanism 35 is fixed to the locking mechanism 34 by a third screw 36. The locking mechanism 35 is fixed to the locking mechanism 34 by a third screw 36. The locking mechanism 35 is fixed to the locking mechanism 34 by a third screw 36. The locking mechanism 35 is fixed to the locking mechanism 34 by a third screw 36. The locking mechanism 35 is fixed to the locking mechanism 34 by a third screw 36. A screw sleeve 9, a first screw rod 7 threadedly sleeved on the inside of the first screw sleeve 9 and a fixed sleeve 8 fixedly sleeved on the outer periphery of the first screw sleeve 9, one end of the first screw sleeve 7 extends to the outside of the first screw sleeve 9 and is fixed with a fixed gear 6 meshing with the toothed disc 5, the fixed sleeve 8 is fixed to the mounting plate 1 through a fixed rod 3, and the fixed cylinder 14 of the movable fixture is fixedly connected to the outer periphery of the first screw sleeve 9 through a plurality of connecting rods 10. When measuring, the two ends of the anchor sleeve are respectively inserted into the fixed cylinder 14 of the fixed fixture and the fixed cylinder 14 of the movable fixture, and the third screw sleeve 30 is rotated forward, so that the third screw rod 36 moves toward the inside of the fixed cylinder 14, and then the anchor sleeve can be clamped by the pressure block 34. When measuring, the transmission motor 23 is started to rotate forward, thereby driving the first screw rod 7 to rotate forward. Under the restriction of the fixed sleeve 8, the first screw 7 rotates forward and drives the first screw sleeve 9 to move to the side away from the fixed fixture, thereby gradually applying tension on the anchor sleeve. When the power unit is running, it can drive the driving parts in the two detection units to run simultaneously.

[0049] The transmission mechanism includes a telescopic shaft rotatably connected to a fixed plate, a turntable 16 fixed to a fixed end of the telescopic shaft, and a blanking assembly for driving the telescopic shaft to rotate in one direction. The turntable 16 is rotatably connected to a handle 26 at a position deviating from the center of a circular surface on one side of the telescopic shaft. The telescopic rod is transmission-connected to the third screw sleeve 30 on the fixed clamp and the movable clamp, and the movable end of the telescopic rod is connected to the fixed cylinder 14 of the movable clamp through a connecting piece. The telescopic shaft includes a movable rod 25 and a sleeve 22 movably sleeved on the outside of one end of the movable rod 25. A sliding groove 32 arranged along its axial direction is provided on the inner wall of the sleeve 22. A slider 33 is fixed to the outer periphery of the movable rod 25, and one end of the slider 33 extends into the sliding groove 32 and slides therewith. The number of the sliding groove 32 and the slider 33 is at least two. The sleeve 22 is rotatably connected to the fixed plate. The connecting piece It includes a connecting sleeve 29 rotatably connected to the outer periphery of the movable rod 25 and a connecting rod fixed to the outer periphery of the connecting sleeve 29, the other end of the connecting rod is fixedly connected to the outer periphery of the fixed tube 14 of the movable clamp. When fixing the anchor cable sleeve, hold the handle 26, and then rotate the turntable 16 clockwise, thereby driving the telescopic shaft to rotate synchronously. After the telescopic shaft rotates, it drives the fixed clamp and the third screw sleeve 30 on the movable clamp to rotate forward synchronously, and then the anchor cable sleeve in the fixed tube 14 can be clamped. Conversely, when the telescopic shaft is rotated counterclockwise, the third screw sleeve 30 can be driven to flip, thereby loosening the anchor cable sleeve clamped in the fixed tube 14. The setting of the turntable 16 and the handle makes it convenient and labor-saving to rotate the telescopic shaft, and the setting of the telescopic shaft will not be affected by the movement of the movable clamp, and the third screw sleeve 30 on the movable clamp can still be driven.

[0050] The blanking assembly includes a transmission gear 19 rotatably sleeved on the outer periphery of the sleeve 22 and an adjusting rack 21 movably mounted on the mounting plate 1. A telescopic member 31 is installed on the mounting plate 1 for driving the adjusting rack 21 to move. The transmission gear 19 cooperates with the adjusting rack 21, and a limiting member is installed between the sleeve 22 and the transmission gear 19 to limit the unidirectional rotation of the sleeve 22 driven by the adjusting rack 21. The inner ring of the transmission gear 19 is provided with a plurality of slots 41, and the outer periphery of the sleeve 22 is provided with a plurality of receiving holes 40 for installing the limiting member. The limiting member includes a first spring installed in the receiving hole 40 and a block 42 movably arranged in the receiving hole. One end of the block is a right-angled triangle structure and is engaged in the slot 41. The other end of the block 42 is fixedly connected to one end of the first spring. The setting of the limiting member makes it possible to move the adjusting rack 21 only when the transmission gear 19 is clockwise. When the telescopic member 31 is retracted, the adjusting rack 21 is driven to move right synchronously. At this time, the adjusting rack 21 drives the transmission gear 19 to rotate clockwise, and the sleeve 22 does not rotate with the transmission gear 19.

[0051] The measuring mechanism includes a fixing ring 2 fixed on the outer wall of the mounting plate 1 and a plurality of detection components mounted on the inner ring of the fixing ring 2 through an elastic member. The axis of the fixing ring 2 is the same as the axis of the fixing cylinder 14. The detection component includes a mounting frame mounted on the elastic member, a roller 12 rotatably mounted on the mounting frame, an angular velocity sensor 11 and a displacement sensor 24. The input end of the angular velocity sensor 11 is connected to the roller 12. The elastic member includes a mounting rod 13 movably inserted into the fixing ring 2, a spring block sleeved on the outer periphery of the mounting rod 13 and a second spring movably sleeved on the outer periphery of the mounting rod 13. One end of the second spring is fixedly connected to the spring block, and the other end of the second spring is fixedly connected to the inner ring of the fixing ring 2. The anchor cable is fixed When the sleeve is in engagement with the roller 12, the roller 12 is pushed toward the side close to the fixing ring 2. At this time, the second spring will be compressed. After the anchor sleeve is fixed, the roller 12 is released. At this time, the roller 12 will be pressed against the outer periphery of the anchor sleeve 12. When the anchor sleeve is subjected to force, the constant resistance body moves in the anchor sleeve. The position of the constant resistance body after movement will cause the sleeve to expand, and the expansion node will drive the roller 12 back to move toward the outside, and then the movement data of the constant resistance body can be obtained in real time through the measurement data of the displacement sensor 24. At the same time, when the constant resistance body moves inside the sleeve, the roller 12 pressed against the outer periphery of the sleeve will rotate accordingly. At this time, the rotation speed of the roller 12 measured by the angular velocity sensor 11 can be used to obtain the movement speed of the constant resistance body.

[0052] In this embodiment, the telescopic member 31 is a hydraulic cylinder.

[0053] The implementation principle of this embodiment is as follows: when measuring, the anchor cable sleeve to be tested is first fixed on the two detection parts respectively. When fixing the anchor cable sleeve, the two ends of the anchor cable sleeve are first inserted into the fixed tube 14 of the fixing fixture and the fixed tube 14 of the movable fixture respectively. Then, the handle 26 is held and the turntable 16 is rotated clockwise until the end of the anchor cable sleeve located in the fixed tube 14 is pressed tightly, thereby completing the fixing of the anchor cable sleeve. Then, the measuring mechanism is adjusted so that the roller 12 in the detection assembly abuts against the outer periphery of the anchor cable sleeve. Then, the transmission motor 23 is started to perform the test.

[0054] When the transmission motor 23 rotates forward, it drives the transmission shaft 4 to rotate forward, and the transmission shaft 4 then drives the gear plate 5 to rotate forward. After the gear plate 5 rotates, it drives the first screw 7 to rotate forward. Under the restriction of the fixed sleeve 8, the first screw 7 drives the first screw sleeve 9 to move to the side away from the fixed fixture after rotating forward, thereby gradually applying tension to the anchor sleeve, making the anchor sleeve tight. As the tension applied to the anchor sleeve gradually increases, the constant resistance body will move in the anchor sleeve. The position of the constant resistance body after movement will cause the sleeve to expand, and the expansion node will drive the roller 12 to move toward the outside, and then the constant resistance body can be obtained in real time through the measurement data of the displacement sensor 24. At the same time, when the constant resistance body moves inside the sleeve, the roller 12 pressed on the outer periphery of the sleeve will rotate accordingly. At this time, the angular velocity sensor 11 measures the rotation speed of the roller 12 to obtain the movement speed of the constant resistance body. After the measurement is completed, the transmission motor is stopped, and then the telescopic member 31 is started to extend. When the adjustment rack 21 is engaged with the transmission gear 19, the transmission gear 19 can be driven to rotate counterclockwise. At this time, the sleeve 22 also rotates counterclockwise with the transmission gear 19 under the action of the limit member, and then the telescopic shaft can be driven to reverse through the telescopic member, thereby loosening the anchor sleeve in the fixed tube 14.

[0055] Example 2:

[0056] Combine Figure 1 - Figure 4 、 Figure 6 and Figure 8 - Figure 9, based on Example 1, this embodiment is further improved in that: a pushing mechanism is installed on both the movable clamp and the fixed clamp, the pushing mechanism includes an air cylinder 15 fixed at the tail of the fixed cylinder 14, a first piston plate 39 installed in the air cylinder 15, a piston column 38 fixed on the outer wall of the first piston plate 39 close to the air cylinder 15, and an air supply assembly installed on the mounting plate 1 for supplying air to the air cylinder 15, one end of the piston column 38 extends into the fixed cylinder 14 and is fixed with a pushing plate 37, the air supply assembly includes a piston cylinder 20 fixed on the mounting plate 1, a second nut 27 rotatably connected to the fixed plate and a second screw 28 threadedly sleeved in the second nut 27, a second piston plate is provided in the piston cylinder 20, one end of the second screw 28 extends into the piston cylinder 20 and is fixed to the outer wall of one side of the second piston plate One end of the second screw sleeve 27 is fixed with a linkage gear 18 that meshes with the adjusting rack 21. An air pipe 17 and a hose 43 are installed on the piston cylinder 20, wherein the other end of the air pipe 17 is connected to the air cylinder 15 on the fixed cylinder 14 in the fixing fixture, and the other end of the hose 43 is connected to the air cylinder 15 on the fixed cylinder 14 in the movable fixture. The movement of the adjusting rack 21 is used to drive the linkage gear 18 and the second screw sleeve 27 to rotate. When the second screw sleeve 27 rotates, it will drive the second screw 28 to move accordingly. After the second screw 28 moves, it drives the second piston plate to move synchronously, so that the air in the piston cylinder 20 can be pressed into the inside of the air cylinder 15, so that the first piston plate 39 moves to the side close to the fixed cylinder 14, and then the push plate 37 can be used to push the anchor sleeve in the fixed cylinder 14 out.

[0057] When the second screw sleeve 27 rotates forward, the second screw rod 28 is driven to move toward the outside of the second screw sleeve 27, so that the air in the piston cylinder 20 can be pressed into the air cylinder 15 on the fixed fixture and the air cylinder 15 on the movable fixture respectively. After the air in the air cylinder 15 increases, it will force the first piston plate 39 to move toward the side close to the fixed cylinder 14, and then drive the piston column 38 and the push plate 37 to move synchronously, so that the anchor cable sleeve released in the fixed cylinder 14 can be pushed out of the fixed cylinder 14. On the contrary, after the telescopic member 31 contracts, it drives the adjusting rack 21 to move right, so that the air in the air cylinder 15 can be sucked back into the interior of the piston cylinder 20 again, and the push plate 37 will also move toward the side close to the air cylinder 15 and finally return to its original position.

Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
