Description

Technical Field

[0001] This utility model relates to the field of anchor technology, and in particular to an anti-detachment anchor. Background Technology

[0002] An anchorage refers to a permanent anchoring device used in prestressed concrete. In post-tensioned structures or components, it is an anchoring tool used to maintain the tension of the prestressing tendons and transfer it into the concrete. It is also called a prestressed anchorage. For example, in publication CN220954216U, "A bidirectional tensioning anti-derailment prestressed anchorage includes an installation plate. Fixing blocks are integrally provided on both sides of the installation plate. A partition is installed in the middle of the installation plate. Connecting blocks are provided on both sides of the partition. A bolt passes through the middle of each connecting block. A guide rod is provided on the outer side of the installation plate, and a limiting plate is installed on the outer side of the guide rod." The limiting plate has evenly spaced connecting holes in its center, and pressure plates are installed inside these connecting holes. By setting up the mounting plate, the steel cable in the center can be clamped and engaged through the partition and the mounting plate, which facilitates the limiting and engagement of the internal steel cable during tensioning, improving the overall stability and strength of the equipment connection. The pressure plates can be clamped and fixed to the steel cable in the center by the restriction of the connecting holes, and the direction of the pressure plates can be flexibly adjusted to meet the adjustment requirements of bidirectional tensioning, further preventing detachment. However, after the steel cable is installed, it is necessary to rotate and adjust the bolts on both sides simultaneously to control the space size of the corresponding slots between the partition and the mounting plate, which is relatively troublesome.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3 As shown, an anti-detachment anchor includes a mounting plate 1, a connecting rod 2 is annularly mounted on the other end surface of the mounting plate 1, a limiting plate 101 is fixedly mounted on the other end surface of the connecting rod 2, a groove 401 is opened on the upper surface of the mounting plate 1, a partition 4 is slidably installed in the groove 401, a connecting hole 3 is opened on the mounting plate 1, the limiting plate 101 and the partition 4, and an installation structure 5 is provided on the front and rear surfaces of the mounting plate 1;

[0020] The mounting structure 5 includes a mounting base 501, a rotating block 502, a first bearing 503, a rotating rod 504, a first bevel gear 505, a second bevel gear 506, a rectangular groove 507, a second bearing 508, a third bearing 509, a rectangular slide 510, a threaded rod 511, a rectangular connecting block 512, and a rectangular slider 513. The mounting base 501 is fixedly mounted on the front and rear surfaces of the mounting plate 1. A rectangular groove 507 is formed inside the mounting base 501. The rectangular groove 507 is located on the front and rear surfaces of the mounting plate 1. A bearing 503 is fixedly installed in the middle of each surface; a rotating rod 504 is installed on the bearing 503, a rotating block 502 is fixedly installed on the front surface of the rotating rod 504, and a bevel gear 505 is fixedly installed on the outer surface of the rotating rod 504 near the front and rear ends; a rectangular groove 510 is opened on the inner front and rear surfaces of the mounting base 501 near the lower end, a bearing 509 is fixedly installed in the middle of the upper and lower surfaces of the rectangular groove 510, and a bearing 509 is fixedly installed on the lower surface of the rectangular groove 507 near the front and rear ends. The system is equipped with a second bearing 508; a threaded rod 511 is installed on the second bearing 508 and the third bearing 509. A rectangular slider 513 is threaded onto the lower end of a rectangular groove 510 on the outer surface of the threaded rod 511. A rectangular connecting block 512 is fixedly installed on the rear surface of the rectangular slider 513. Rectangular connecting blocks 512 are fixedly installed on both the front and rear surfaces of the partition 4. A second bevel gear 506 is fixedly installed on the upper surface of the threaded rod 511. A first bevel gear 505 fixedly installed on the outer surface of the rotating rod 504 near the front and rear ends meshes with the second bevel gear 506 fixedly installed on the upper surface of the threaded rod 511. After the steel cable is installed, the rotating block 502 can be rotated to make the rectangular slider 513 slide upward in the rectangular groove 510, thereby driving the rectangular connecting block 512 fixedly installed on the rear surface of the rectangular slider 513 to move upward. The rectangular connecting block 512 drives the partition 4 to move upward in the first groove 401, thereby controlling the space size of the corresponding slot between the partition 4 and the mounting plate 1.

[0021] It should be noted that this utility model is an anti-detachment anchor. After the steel cable is installed, firstly rotate the rotating block 502, so that the rotating block 502 drives the rotating rod 504 to rotate on the first bearing 503, thereby driving the first bevel gear 505 fixedly installed near both ends of the outer surface of the rotating rod 504 to rotate. Because the first bevel gear 505 fixedly installed near the front and rear ends of the outer surface of the rotating rod 504 meshes with the second bevel gear 506 fixedly installed on the upper surface of the threaded rod 511, the threaded rod 511 is driven to rotate on the third bearing 509, so that the rectangular slider 513 fixedly installed near the lower end of the outer surface of the threaded rod 511 slides in the rectangular slide groove 510, thereby driving the rectangular connecting block 512 fixedly installed on the rear surface of the rectangular slider 513 to move upward, so that the rectangular connecting block 512 drives the partition 4 to move upward in the first groove 401, thereby controlling the space size of the corresponding hole groove between the partition 4 and the mounting plate 1.
