Description

Technical Field

[0001] The invention belongs to the technical field of anchor cable testing, and in particular relates to an anchor cable testing device for a low-tower cable-stayed bridge. Background Art

[0002] Anchor cables refer to the process of anchoring the main cable in the side holes of a suspension bridge. The main cable is divided into many steel bundles and anchored in anchor ingots respectively. These steel bundles are called anchor cables. The anchor cable is fixed to the slope surface at the outer end and anchored in the stable rock mass within the sliding surface at the other end. The prestressed steel strands pass through the sliding surface of the slope. Anchor cables and anchor rods are often used in bridges.

[0003] For example, a bridge tension anchor dynamometer disclosed in national patent publication number CN217980618U includes a measuring table holder that can be carried by staff through a binding device. Specifically, the fixing bar is inserted into the clothes or waist, and the measuring table holder can be placed on the waist through the reserved groove of the fixing bar to avoid loss of the measuring table holder. It can also be tied to the hand through a connecting belt to avoid frequent taking or loss.

[0004] However, the conventional device still has the following problems when used: Since there will be a certain gap between the clothes, waist and body by simply inserting the fixing strip into the clothes and waist, it cannot be ensured that the fixing strip will not fall off the clothes or waist. In addition, the length of the connecting belt is fixed, so the length of the connecting belt during bundling is also limited, which reduces the practicality of the bundling device and increases the possibility of the anchor test device falling.

The two groups of guide rods 21 are respectively located on both sides of the card slot 20. The two groups of guide rods 21 play a limiting role on the fixing belt 13 and the fixed teeth 14, so that the fixing belt 13 can fit with the bottom of the accommodating cavity 7. The fixed teeth 14 are equidistant and equal in size and are fixed on the top surface of the fixing belt 13. The mounting assembly includes a positioning ball 15 and a connecting plate 16. The connecting plate 16 is a square plate. Structure, there are three groups of positioning balls 15 fixed, and the three groups of positioning balls 15 are fixed on the surface of the connecting plate 16 at equal distances and sizes. A limiting groove 17 is provided on one side of the connecting plate 16, and the limiting groove 17 is an "L"-shaped plate groove, and the end of the strap 18 is integrally formed with a limiting block 19, which is an "L"-shaped plate. The limiting block 19 passes through the extension groove 36 and is movably inserted into the limiting groove 17. The extension groove 36 is provided on the side of the integral block 6, and the side of the integral block 6 is provided with a side groove 22. The side groove 22 is connected with the accommodating cavity 7 and the extension groove 36.

The baffle 24 is in active contact with the outer annular surface of the positioning ball 15 and the connecting plate 16.

[0032] In the present invention, the starting motor 8 drives the linkage rod 9 to rotate, and the linkage rod 9 rotates to drive the installation belt 12 and the fixed belt 13 to start winding and moving. Since the bottom of the auxiliary plate 29 is between the two sets of guide rods 21, that is, the matching teeth 30 are no longer engaged with the fixed teeth 14, it is ensured that when the fixed belt 13 moves, the matching teeth 30 will not hinder the movement of the fixed belt 13, that is, the fixed teeth 14 as a whole. The two sets of guide rods 21 play a guiding role on the fixed belt 13 and the fixed teeth 14, ensuring that the fixed belt 13 and the fixed teeth 14 as a whole can always fit and move with the bottom of the accommodating cavity 7 until the positioning ball 15 is aligned with a set of guide rods. 21 active contact, the motor 8 stops rotating and rotates; then the auxiliary rod 28 is rotated to drive the extension frame 31 to rotate, so that the positioning frame 32 no longer contacts the top of the positioning frame 32, and the auxiliary rod 28 is adjusted to the state of the extension frame 31 to rotate back into the limiting slot 37. At this time, the matching teeth 30 are re-engaged with the fixed teeth 14 to complete the limiting of the fixing belt 13 and the fixed teeth 14 as a whole, that is, to complete the fixation of the positioning ball 15. Since the positioning ball 15 is now inside the accommodating chamber 7, the strap 18 is in a closed state as a whole, which is convenient for the staff to wear the strap 18 on the arm.

[0033] Adjust the auxiliary rod 28 so that the matching tooth 30 is no longer engaged with the fixed tooth 14. At this time, the fixing belt 13 and the fixed tooth 14 lose their limit as a whole. Pull the strap 18 to drive the fixing belt 13 and the fixed tooth 14 to move as a whole until the positioning ball 15 is located in the side groove 22. Please refer to Figure 3 and Figure 4 As shown, the positioning ball 15 will be in active contact with the surface of the protrusion 26, and the baffle 24 and the protrusion 26 will limit the positioning ball 15. Under the action of the damping protrusion fixed on the surface of the positioning ball 15 in active contact with the protrusion 26, and when the staff pulls the strap 18 with external force, the positioning ball 15 will not easily fall out of the side groove 22. Then the strap 18 is pulled out from the extension groove 36, and the limit block 19 will slide out along the limit groove 17, which is convenient for the staff to wrap the strap 18 around the waist and other places where it needs to be placed. After wrapping, the limit block 19 can be slid back into the limit groove 17 along the extension groove 36. The whole is convenient for carrying the test device, and it is convenient to carry the test device in two forms at different positions on the body, and it will not fall easily.

[0034] The third embodiment, on the basis of the second embodiment, the limiting component includes an auxiliary rod 28, an auxiliary plate 29, and a matching tooth 30. The auxiliary rod 28 is a "T"-shaped column structure. The auxiliary rod 28 is movably plugged into the top of the integrated block 6. The bottom end of the auxiliary rod 28 is located in the accommodating cavity 7. The auxiliary plate 29 is rotatably connected to the bottom of the auxiliary rod 28. The auxiliary plate 29 is a square plate. The auxiliary plate 29 is located in the accommodating cavity 7. The matching tooth 30 is fixed to the bottom of the auxiliary plate 29. There are multiple groups of matching teeth 30 fixed, and the multiple groups of matching teeth 30 are distributed at equal distances and sizes. The top of the auxiliary plate 29 is located in the card slot 20. The matching teeth 30 are meshed with the fixed teeth 14. The two groups of guide rods 21 are respectively located on both sides of the auxiliary plate 29. A circular groove is provided on the top of the integrated block 6. The auxiliary rod 28 is movably plugged into the top of the integrated block 6. The bottom end of the auxiliary rod 28 is located in the accommodating cavity 7. The auxiliary plate 29 is rotatably connected to the bottom of the auxiliary rod 28. The auxiliary plate 29 is a square plate. The auxiliary plate 29 is located in the accommodating cavity 7. The matching tooth 30 is fixed to the bottom of the auxiliary plate 29. The cam 33 is a ring-shaped plate, and the spring 35 is fixed to the bottom of the top plate of the auxiliary rod 28. The cam 33 is a ring-shaped plate, and the spring 35 is fixed to the bottom of the top plate of the auxiliary rod 28. The cam 33 is a ring-shaped plate, and the spring 35 is fixed to the bottom of the top plate of the auxiliary rod 28. The cam 33 is a ring-shaped plate, and the spring 35 is fixed to the top of the auxiliary rod 28.

[0035] In the present invention, please refer to Figure 2 When the auxiliary rod 28 is rotated, the rotating ring 33 rotates in the rotating groove 34 to prevent the spring 35 from twisting when the auxiliary rod 28 is rotated.

[0036] The working principle and use process of this invention: please refer to Figure 2The auxiliary rod 28 is rotated to disengage the extension frame 31 from the extension slot 36, and the top of the auxiliary rod 28 is pulled to drive the auxiliary rod 28 and the auxiliary plate 29 to move synchronously toward the top of the integrated block 6 until the extension frame 31 is higher than the top of the positioning frame 32. The auxiliary rod 28 is rotated again to drive the extension frame 31 so that the extension frame 31 overlaps the top of the positioning frame 32. At this time, the bottom of the auxiliary plate 29 is between the two sets of guide rods 21, and the motor 8 is started to drive the linkage rod 9 to rotate. The linkage rod 9 rotates to drive the installation belt 12 and the fixing belt 13 to start winding and moving. Since the bottom of the auxiliary plate 29 is between the two sets of guide rods 21, the matching teeth 30 are no longer engaged with the fixing teeth 14 to ensure that the matching teeth 30 will not hinder the movement of the fixing belt 13, that is, the fixing teeth 14 as a whole when the fixing belt 13 moves. The two sets of guide rods 21 play a guiding role for the fixing belt 13 and the fixing teeth 14 to ensure that the fixing belt 13 and the fixing teeth 14 as a whole can always be aligned with the bottom of the accommodating cavity 7. When the cam 15 is in the closed position, the motor 8 stops rotating and the auxiliary rod 28 is turned to rotate. The auxiliary rod 28 drives the extension frame 31 to rotate so that the positioning frame 32 is no longer in contact with the top of the positioning frame 32, and the auxiliary rod 28 is adjusted to the state of the extension frame 31 to rotate back into the extension groove 36. At this time, the matching teeth 30 are meshed with the fixing teeth 14 again, completing the limiting of the fixing belt 13 and the fixing teeth 14 as a whole, that is, completing the fixing of the positioning ball 15. Since the positioning ball 15 is now in the accommodating cavity 7, the strap 18 is in a closed state as a whole, which is convenient for the staff to wear the strap 18 on the arm.
