Description

Technical Field

[0001] The utility model relates to the technical field of prestressed anchors, in particular to a steel strand anti-loosening anchor. Background Art

[0002] Solar energy is an important new energy source, and photovoltaic brackets are structures used to support solar panels in solar photovoltaic power generation systems. With the further development of solar photovoltaic power generation technology, photovoltaic power generation projects in complex environments such as mountains, water surfaces, Gobi, deserts, and bays have gradually been carried out. In terms of the selection of photovoltaic brackets, rigid brackets are difficult to apply to complex geographical conditions due to their limitations such as non-adjustability after fixation, poor wind resistance, and weak corrosion resistance. However, the flexible prestressed bracket using steel strand cables has been increasingly used in projects in complex terrain areas because it can better improve the support method of photovoltaic power generation systems with larger spans, has high environmental space utilization, and has low cost.

[0003] The existing strand anti-loosening anchor is composed of a cone surface of an impact-resistant anchor ring and a cone surface at the outer end of a splitter. The strand is squeezed under the dual effects of the axial tension of the strand and the clamping of the cone surface structure, providing prestress for the strand. However, in this method, the strand and the splitter are often not fully in contact with each other due to misalignment during assembly, causing the splitter that is in excessive contact to wear excessively and eventually fail.

[0004] Therefore, there is an urgent need for a steel strand anti-loosening anchor to solve the above-mentioned problem. Utility Model Content

It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It should also be noted that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components.

[0032] like Figures 1 to 3 As shown, the steel strand anti-loosening anchor of this embodiment includes an anti-loosening anchor body 1 and a first extrusion bolt 2. The anti-loosening anchor body 1 is provided with a penetration channel 11, a first threaded hole 12 and a first extrusion space 13. The penetration channel 11 can allow the steel strand 100 to penetrate the anti-loosening anchor body 1, the first threaded hole 12 is connected to one side of the penetration channel 11 along the radial direction of the penetration channel 11, the first extrusion space 13 is connected to the other side of the penetration channel 11 in the radial direction, and the first extrusion space 13 is arranged corresponding to the first threaded hole 12. In this embodiment, the anti-loosening anchor body 1 is a cylindrical structure, and the penetration channel 11 is arranged axially along the anti-loosening anchor body 1; in some other embodiments, the anti-loosening anchor body 1 can also be a polygonal columnar structure, etc. The first extrusion bolt 2 is penetrated in the first threaded hole 12 and can extrude the steel strand 100.

[0033] The utility model provides a steel strand anti-loosening anchor, in which the steel strand 100 passes through the anti-loosening anchor body 1 through the penetration channel 11, and the first extrusion bolt 2 can be penetrated in the first threaded hole 12 until the first extrusion bolt 2 can abut against the steel strand 100. At this time, the first extrusion bolt 2 is continued to be inserted into the first threaded hole 12, so that the first extrusion bolt 2 squeezes the steel strand 100 to cause tensile deformation, and the tensile deformed part of the steel strand 100 is squeezed into the first extrusion space 13, so that the steel strand 100 is stretched to generate prestress. The steel strand anti-loosening anchor has a simple structure and can be quickly installed. It does not need to use other devices to apply prestress to the steel strand 100. It is firm and durable, and the deformation degree of the steel strand 100 can be changed by adjusting the length of the first extrusion bolt 2 inserted into the first threaded hole 12, thereby adjusting the prestress of the steel strand 100, thereby expanding the applicable scenarios of the steel strand anti-loosening anchor.

[0034] Continue to refer to Figure 1 The anti-loosening anchor body 1 includes two main body units 16, which respectively form two sides of the penetration channel 11. The two main body units 16 can be directly buckled on the steel strand 100, making the installation of the anti-loosening anchor body 1 more convenient. Preferably, the first threaded hole 12 and the first extrusion space 13 are arranged on different main body units 16 to ensure the integrity of the first threaded hole 12 and the first extrusion space 13, which is convenient for processing.

[0035] Furthermore, the ends of the two main units 16 are provided with connecting threads 161, and the stranded wire anti-loosening anchor further includes a connecting nut 4, which is connected to the connecting thread 161, so that the two main units 16 can be connected through the connecting nut 4. In this embodiment, both ends of the main unit 16 are provided with connecting threads 161, and two connecting nuts 4 are provided, which are respectively connected to the two ends of the two main units 16, so as to ensure the structural stability of the anti-loosening anchor body 1.

[0036] Furthermore, the connection nut 4 is provided with an anti-loosening structure. In the present embodiment, the anti-loosening structure comprises an anti-loosening hole 41 and an anti-loosening screw 42. The anti-loosening hole 41 penetrates the side wall of the connection nut 4 along the radial direction of the connection nut 4. When the connection nut 4 is connected to the connection thread 161, the anti-loosening screw 42 is passed through the anti-loosening hole 41 and abuts against the anti-loosening anchor body 1 to prevent the connection nut 4 from loosening. In some other embodiments, the anti-loosening structure may also adopt other types of anti-loosening structures, such as adopting a self-locking nut, using an anti-loosening washer, etc.

[0037] In order to prevent the first extrusion bolt 2 from loosening, when the first extrusion bolt 2 reaches a suitable position, the connecting nut 4 and the connecting thread 161 can be tightened so that the connecting nut 4 is close to the head of the first extrusion bolt 2. When the first extrusion bolt 2 rotates, the connecting nut 4 can abut against the head of the first extrusion bolt 2 in the radial direction of the first extrusion bolt 2, thereby preventing the first extrusion bolt 2 from rotating.

[0038] like Figure 2 As shown, the anti-loosening anchor body 1 is also provided with a second threaded hole 14 and a second extrusion space 15, the second threaded hole 14 is arranged at intervals from the first threaded hole 12 in the extension direction of the penetration channel 11, the second threaded hole 14 is connected to one side of the penetration channel 11 along the radial direction of the penetration channel 11, and the second extrusion space 15 is connected to the other side of the penetration channel 11 in the radial direction and is arranged corresponding to the first threaded hole 12. Further, the steel strand anti-loosening anchor also includes a second extrusion bolt 3, which is passed through the second threaded hole 14 and can extrude the steel strand 100. Such an arrangement can further expand the tensile deformation degree of the steel strand 100, thereby expanding the scope of application of the steel strand anti-loosening anchor.

[0039] Preferably, the first threaded hole 12 and the second extrusion space 15 are located on the same side of the penetration channel 11 and on one main body unit 16, and the second threaded hole 14 and the first extrusion space 13 are located on the same side of the penetration channel 11 and on the other main body unit 16. Such an arrangement enables the first extrusion bolt 2 and the second extrusion bolt 3 to extrude the steel strand 100 in different directions, thereby preventing fatigue damage to the steel strand 100 after long-term use. In addition, such an arrangement enables the two main body units 16 to have the same structure, and the above functions can be achieved by simply installing the two main body units 16 in different directions, thereby reducing the production cost increased by producing main body units 16 with different structures.

[0040] Furthermore, the anti-loosening anchor body 1 is further provided with a fixing groove 17 , and the head of the first extrusion bolt 2 can abut against the bottom surface of the fixing groove 17 , so that the connection between the first extrusion bolt 2 and the first threaded hole 12 is more stable.

[0041] The steel strand anti-loosening anchor provided by the utility model firstly fastens the two main body units 16 on the steel strand 100, and respectively connects the connecting threads 161 at both ends of the two main body units 16 by using two connecting nuts 4, at this time, it is only necessary to ensure that the two main body units 16 can not be separated; then, the first extrusion bolt 2 is inserted into the first threaded hole 12 until part of the steel strand 100 is squeezed into the first extrusion space 13, and the second extrusion bolt 3 is inserted into the second threaded hole 14 until part of the steel strand 100 is squeezed into the second extrusion space 15; the two connecting nuts 4 are continuously tightened so that the two connecting nuts 4 are respectively close to the first extrusion bolt 2 and the second extrusion bolt 3 to prevent the first extrusion bolt 2 and the second extrusion bolt 3 from rotating; finally, the anti-loosening screw 42 is screwed into the anti-loosening hole 41 and abuts against the main body unit 16 to realize the anti-loosening of the connecting nut 4.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
