Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 6 As shown, a stress detection device for steel strand detection comprises a base 1, two movable plates 2 are movably arranged on the upper surface of the base 1, a movable rotating column 3 is movably arranged on the upper ends of the two movable plates 2, and a mounting groove 4 is opened through the surface of the rotating column 3;

[0027] A first motor 5 is fixedly mounted on one side of the inner wall of the two mounting grooves 4. The two first motors 5 are fixedly mounted on one side of the inner wall of the corresponding mounting grooves 4. A first bidirectional screw rod 501 is fixedly mounted on the output shaft end of the two first motors 5. One end of the two first bidirectional screw rods 501 is rotatably connected to the other side of the inner wall of the mounting groove 4. Slide plates 502 are threadedly arranged on both sides of the rod body of the two first bidirectional screw rods 501. Clamp plates 503 are fixedly mounted on the opposite sides of the two slide plates 502.

[0028] A slide bar 504 is fixedly installed between the two inner walls of the two installation grooves 4, and two slide plates 502 are slidably arranged on the two sides of the corresponding slide bar 504.

[0029] A slide groove 6 is provided on the upper surface of the base 1, and two sliders 601 are slidably arranged in the slide groove 6. The two movable plates 2 are respectively fixedly mounted on the upper surfaces of the corresponding sliders 601. A second bidirectional screw rod 602 is rotatably mounted between the two sides of the inner wall of the slide groove 6. The two sliders 601 are respectively threadedly arranged on the two sides of the corresponding second bidirectional screw rod 602.

[0030] A second motor 7 is fixedly mounted on one side of the base 1 , and one end of the second bidirectional screw rod 602 passes through the base 1 and is fixedly connected to the output shaft end of the second motor 7 .

[0031] The staff passes the two ends of the steel strand through the installation groove 4, and then starts the first motor 5, so that its output shaft end drives the first bidirectional screw rod 501 to rotate. The rotating first bidirectional screw rod 501 drives the adjacent slide plate 502 to move relative to each other by screwing in the thread, so that the clamping plate 503 clamps the end of the strand. Then the staff controls the rotation of the rotating column 3 to make a part of the steel strand wrapped around the column body of the rotating column 3. After the strand is wrapped around the column body of the rotating column 3, the contact area between the strand and the rotating column 3 increases, which increases the friction force and makes it difficult for the strand to slip off the rotating column 3, which greatly enhances the fixing effect of the steel strand and avoids the displacement of the steel strand after being pressed by the pressure block during the detection process, thereby ensuring the accuracy of the detection data of the steel strand and avoiding affecting the subsequent use of the steel strand.

[0032] In another embodiment of the utility model, a rotating shaft 8 is rotatably mounted in the middle of the upper surfaces of the two movable plates 2 , and the upper ends of the two rotating shafts 8 are fixedly connected to the corresponding rotating columns 3 .

[0033] The two moving plates 2 are both installed with electric guide rails 9 on the side away from each other, the moving ends of the two electric guide rails 9 are arranged opposite to each other, and the moving ends of the two electric guide rails 9 are both fixedly installed with racks 901;

[0034] One side of the two rotating shafts 8 is sleeved with a gear 10 , and the two racks 901 are respectively meshed with the corresponding gears 10 .

[0035] The staff starts the electric guide rail 9 to drive the rack 901 to move. Under the meshing action of the rack 901 and the gear 10, the gear 10 drives the rotating shaft 8 to rotate, so that the rotating column 3 rotates.

[0036] In another embodiment of the utility model, the two rotating columns 3 are both provided with two retaining rings 11;

[0037] The two rotating columns 3 are each provided with a connecting groove 12, and a third bidirectional screw rod 1201 is rotatably installed between the two inner walls of the two connecting grooves 12, and two connecting blocks 1202 are slidably arranged in the two connecting grooves 12, and the adjacent connecting blocks 1202 are respectively threadedly arranged on both sides of the corresponding third bidirectional screw rod 1201 rod body, and the upper ends of the two third bidirectional screw rods 1201 respectively pass through the corresponding connecting grooves 12 and are fixedly installed with a rotating wheel 1203.

[0038] The staff rotates the rotating wheel 1203 so that the third bidirectional screw rod 1201 drives the adjacent retaining ring 11 to move by screwing in the thread, so that the retaining ring 11 can clamp the wound stranded wire, further improving the clamping effect.

[0039] The working principle of the stress detection device for steel strand detection:

[0040] During use, the staff passes the two ends of the steel strand through the installation groove 4, and then the staff starts the first motor 5, so that its output shaft end drives the first bidirectional screw rod 501 to rotate, and the rotating first bidirectional screw rod 501 drives the adjacent slide plate 502 to move relative to each other by screwing in, so that the clamping plate 503 clamps the end of the strand, and then the staff controls the rotation column 3 to rotate, so that a part of the steel strand is wound around the column body of the rotating column 3. After the strand is wound around the column body of the rotating column 3, the contact area between the strand and the rotating column 3 increases, so that the friction force increases, and it is difficult for the strand to slip off the rotating column 3, which greatly enhances the fixing effect of the steel strand and avoids the displacement of the steel strand after being pressed by the pressure block during the detection process, thereby ensuring the accuracy of the detection data of the steel strand and avoiding affecting the subsequent use of the steel strand.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
