Description

Technical Field

[0001] This invention belongs to the field of civil engineering technology, specifically relating to a steel tie rod structure that can be quickly tensioned and locked. Background Technology

[0002] Steel tie rods are widely used in buildings requiring large-span floor or roof structures, bridges, crane rails, curtain wall structures, etc., to connect various components, providing greater coverage area and load-bearing capacity while maintaining structural stability and safety. Steel tie rods are typically connected to the main structure via pins and require a certain preload according to design requirements.

[0003] Because the tensioning of steel tie rods requires high torque, traditional tensioning operations involve frequent manual rotation of the adjusting sleeve using an adjusting wrench to lock the rod due to the connecting parts in the radial direction. This results in low construction efficiency. Therefore, it is necessary to propose a steel tie rod that can be locked after being tensioned in one go, eliminating the need for frequent rotation of the adjusting sleeve during the tensioning process. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a steel tie rod structure that can be quickly tensioned and locked, and to provide a steel tie rod that can be locked after being tensioned in one go, without the need for frequent rotation of the adjusting sleeve for locking during the tensioning process.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention provides a steel tie rod structure capable of rapid tensioning and locking, comprising: two coaxially arranged steel tie rods and an adjusting sleeve threadedly connected to both steel tie rods. Each adjusting sleeve includes a fixed sleeve, within which an adjusting sleeve threadedly connected to each of the two steel tie rods is rotatably mounted. The two adjusting sleeves are symmetrically arranged. Two sets of gears are rotatably mounted on the fixed sleeve between the two adjusting sleeves. The two sets of gears are symmetrically arranged, each gear set including multiple gears circumferentially arranged around the center of the fixed sleeve. The shafts of the multiple gears in the same set are located on the same plane, and the gears in the first gear set mesh with adjacent gears in the second gear set. A gear ring is provided on the adjusting sleeve near the gears, meshing with the multiple gears in the same set. Rotating the gears causes the adjusting sleeve to rotate.

[0007] Furthermore, the fixed cylinder is provided with a sliding groove corresponding to a plurality of gears, and a sliding rod is slidably installed in the sliding groove, and the gear is rotatably installed on the sliding rod.

[0008] Furthermore, an adjusting ring is rotatably mounted on the fixed cylinder. The adjusting ring has multiple arc-shaped grooves that correspond one-to-one with the slide rods. The slide rods have connecting rods that extend into the arc-shaped grooves. Rotating the adjusting ring allows the connecting rods to slide along the arc-shaped grooves, thereby allowing the slide rods to slide along the grooves.

[0009] Furthermore, the adjusting cylinder is rotatably mounted inside the fixed cylinder via a bearing.

[0010] Furthermore, the fixed cylinder includes an outer cylinder and an inner cylinder connected to the inner side of the outer cylinder. The adjusting cylinder is slidably installed inside the outer cylinder. The inner cylinder is disposed between the two adjusting cylinders. The inner diameter of the inner cylinder is consistent with the outer diameter of the steel tie rod. An operating rod is connected to the adjusting ring. The outer cylinder is provided with a limiting groove that cooperates with the operating rod. The operating rod is slidably installed in the limiting groove.

[0011] The beneficial effects of this invention are as follows:

[0012] This invention avoids the influence of the connecting parts in the radial direction of the steel tie rod, which would otherwise require frequent use of an adjusting wrench to rotate a certain angle, realign, and then rotate again to lock it.

[0013] Other advantages, objectives, and features of the invention will be set forth in the following description and will be apparent to those skilled in the art in some respects, or may be learned by practice of the invention. The objectives and other advantages of the invention can be realized and obtained through the following description. Attached Figure Description

[0019] The following components are marked in the attached diagram: steel tie rod 1, adjusting sleeve 2, fixed cylinder 201, outer cylinder 2011, inner cylinder 2012, limiting groove 2013, adjusting cylinder 202, gear 203, gear ring 204, sliding groove 205, sliding rod 206, connecting rod 207, adjusting ring 3, arc groove 301, and operating rod 302. Detailed Implementation

[0020] like Figures 1-4 As shown, this invention provides a steel tie rod structure capable of rapid tensioning and locking, comprising: two coaxially arranged steel tie rods 1 and an adjusting sleeve 2 threadedly connected to both steel tie rods 1. The adjusting sleeve 2 includes a fixed sleeve 201, within which an adjusting sleeve 202, threadedly connected to each of the two steel tie rods 1, is rotatably mounted. The two adjusting sleeves 202 are symmetrically arranged; rotating the two adjusting sleeves 202 allows the two steel tie rods 1 to move and lock. Two sets of [unclear text - possibly related to a specific type of steel tie rod structure] are rotatably mounted on the fixed sleeve 201 between the two adjusting sleeves 202. Two sets of gears 203 are symmetrically arranged. Each set of gears 203 includes multiple gears 203 arranged circumferentially around the center of the fixed cylinder 201. The axes of the multiple gears 203 in the same set are located on the same plane, and the gears 203 in the first set of gears 203 mesh with the adjacent gears 203 in the second set of gears 203. The adjusting cylinder 202 is provided with a gear ring 204 near the gears 203, which meshes with the multiple gears 203 in the same set. Rotating the gears 203 can make the adjusting cylinder 202 rotate.

[0021] In this solution, after the steel tie rod 1 is tensioned into place, when locking the two steel tie rods 1, a tool can be used to drive the gear 203 to rotate. This tool can be a socket wrench for manual driving or a drive motor output shaft connected to one of the gears 203 for electric driving. When one gear 203 rotates, it can drive the other gear 203 meshing with it to rotate, thereby driving the corresponding gear rings 204 on the two adjusting cylinders 202 to rotate, so that the two adjusting cylinders 202 rotate simultaneously in the same direction. This avoids the influence of the connecting parts in the radial direction of the steel tie rod, which would otherwise require frequent use of the adjusting wrench to rotate a certain angle and then realign and rotate again to lock.

[0022] In one embodiment of the present invention, the fixed cylinder 201 is provided with a sliding groove 205 corresponding to a plurality of gears 203. A sliding rod 206 is slidably installed in the sliding groove 205. The gears 203 are rotatably installed on the sliding rod 206. An adjusting ring 3 is rotatably installed on the fixed cylinder 201. The adjusting ring 3 is provided with a plurality of arc-shaped grooves 301 corresponding to a plurality of sliding rods 206. A connecting rod 207 extending into the arc-shaped groove 301 is provided on the sliding rod 206. Rotating the adjusting ring 3 can cause the connecting rod 207 to slide along the arc-shaped groove 301 so that the sliding rod 206 slides along the sliding groove 205.

[0023] In this plan, such as Figure 3Both sets of gears 203 have adjusting rings 3 rotatably mounted on one side. When the adjusting rings 3 are rotated, the connecting rods 207 connected to the gears 203 in the same set of gears 203 slide along the arc-shaped grooves 301, thereby driving the sliding rods 206 to slide along the sliding grooves 205. This allows the gears 203 in this set of gears 203 to mesh or disengage with the adjacent gear rings 204 and the gears 203 in the adjacent sets of gears 203. When a gear 203 in the same set disengages from the gear rings 204, it also disengages from the gears 203 in the other set. At this time, rotating the other set of gears 203 can only drive the meshing gear ring 204 to rotate, that is, only one adjusting cylinder 202 rotates, thereby adjusting the position of one of the steel tie rods 1 for tensioning operation. Compared with the prior art in which rotating the adjusting sleeve 2 drives the two steel tie rods 1 to move closer synchronously for tensioning, this solution can adjust the displacement of one of the steel tie rods 1 when it is tensioned, which increases the scope of application and facilitates the connection between the adjusting cylinder 2 and the steel tie rod 1 during installation; and the setting of the adjusting ring 3 makes the adjustment convenient.

[0024] In one embodiment of the present invention, the adjusting cylinder 202 is rotatably mounted inside the fixed cylinder 201 via a bearing.

[0025] In this solution, bearings are used to reduce friction between the fixed cylinder 201 and the adjusting cylinder 202, thereby ensuring the smooth rotation of the adjusting cylinder 202 and reducing the torque required when rotating the gear 203.

[0026] In one embodiment of the present invention, the fixed cylinder 201 includes an outer cylinder 2011 and an inner cylinder 2012 connected to the outer cylinder 2011. The adjusting cylinder 202 is slidably installed inside the outer cylinder 2011. The inner cylinder 2012 is disposed between the two adjusting cylinders 202. The inner diameter of the inner cylinder 2012 is consistent with the outer diameter of the steel tie rod 1. An operating rod 302 is connected to the adjusting ring 3. The outer cylinder 2011 is provided with a limiting groove 2013 that cooperates with the operating rod 302. The operating rod 302 is slidably installed in the limiting groove 2013.

[0027] In this plan, such as Figure 3 The operating lever 302 extends from the limiting groove 2013 to the outside of the outer cylinder 2011, so that the operator can rotate the adjusting ring 3 by operating the operating lever 302, making the operation convenient. When the operating lever 302 slides from the first end to the second end of the limiting groove 2013, it can make the corresponding gear 203 and the gear ring 204 go from meshing to disengaging, making it easy for the operator to distinguish the meshing state of the gear 203.

[0028] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
