Description

Technical Field

[0001] This application belongs to the field of power fittings technology, and more specifically, relates to a pull rod for pull wire connections. Background Technology

[0002] In fields such as power engineering, communication engineering, and civil engineering, guy poles serve as core auxiliary components to ensure the stability of tall structures. Through their synergistic action with guy wires such as steel strands and steel wire ropes, they transfer the horizontal tension and overturning forces on structures such as power poles, communication towers, and construction supports to the underground fixed end, thereby effectively suppressing the risk of structural tilting and collapse. They are an indispensable key facility in outdoor engineering.

[0003] Currently, in use, one end of the guy pole is buried underground and fixed by backfilling and compaction. While this method can meet the foundation fixing requirements, in complex working conditions and harsh environments, the buried end of the guy pole is prone to settlement and pull-out, causing the guy pole to completely fail. Utility Model Content

[0004] The purpose of this application is to provide a guy rod for guy wire connection, so as to solve the technical problem that the buried end of the guy rod is prone to settlement and pull-out, which leads to the complete failure of the guy rod.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a pull bar for pull cable connection, comprising: A fixing block is used to be buried underground; the fixing block is provided with a mounting cavity, and the fixing block is provided with a first through hole located at the bottom of the mounting cavity; A support plate is horizontally positioned and fixedly installed on the fixing block; the support plate is located above the mounting cavity, and a second through hole is provided on the support plate; The connecting post has a connecting hole that extends through the axis, and the connecting hole is arranged coaxially with the second through hole; An anchor is inserted into the mounting cavity, with its lower end passing through the first through hole, for anchoring the fixing block to the ground; The upper end of the pull rod body is used to connect with the pull wire, and the lower end passes through the connecting hole and the second through hole, and is used to fix it to the connecting post.

[0006] In one possible implementation, the fixing block includes a base plate and two side plates respectively fixedly installed on both sides of the base plate, the base plate and the two side plates forming the mounting cavity; the first through hole is opened on the base plate, and the two ends of the bearing plate are respectively fixedly connected to the two side plates.

[0007] In one possible implementation, support blocks are fixed on the inner walls of both side plates, and the two ends of the bearing plate are respectively supported and fixed on the two support blocks.

[0008] In one possible implementation, the support block has a through T-slot, and the lower end of the bearing plate has a T-block that cooperates with the slider of the T-slot.

[0009] In one possible implementation, the two side plates are symmetrically arranged on both sides of the base plate, and the included angle between the side plates and the base plate is an obtuse angle.

[0010] In one possible implementation, the support plate is located in the middle of the mounting cavity, and there are two of each of the first through holes and the anchors, which are symmetrically arranged on both sides of the support plate.

[0011] In one possible implementation, the outer surface of the anchor has an external threaded section and a threaded locking nut, the locking nut being used to fix the anchor to the fixed block.

[0012] In one possible implementation, the outer side of the pull rod body is provided with an external thread section and two threaded locking nuts, the two locking nuts being located at the upper end of the connecting column and the lower end of the bearing plate, respectively; the two locking nuts are used to fix the pull rod body, the connecting column and the bearing plate.

[0013] In one possible implementation, the outer surface of the fixed block is provided with multiple extension ribs.

[0014] In one possible implementation, the outer wall of the fixing block is provided with a flow guiding through hole that communicates with the plurality of mounting cavities.

[0015] The beneficial effects of the guy rod for guy wire connection provided in this application are as follows: Compared with the prior art, the guy rod for guy wire connection in this application utilizes a fixed block and anchors to construct a solid underground bearing foundation, and combines a bearing plate and connecting column to achieve a stable connection between the guy rod body and the fixed block, ultimately ensuring the effective transmission of guy wire tension. The fixed block in this guy rod, as the core bearing component, is buried underground. Its internal installation cavity provides space for the installation of anchors and also provides space for backfill soil. The first through hole at the bottom provides a channel for the lower end extension of the anchor, ensuring that the anchor can penetrate deep underground for anchoring. The horizontally positioned bearing plate is fixed to the fixed block and located above the installation cavity. Its second through hole is coaxial with the axial connection hole of the connecting column, providing precise positioning for the installation of the guy rod body and avoiding uneven stress caused by installation deviations. The anchors bear the primary responsibility for resisting pull-out and lateral displacement. Through a structure that penetrates the installation cavity and extends deep into the ground, they firmly anchor the fixed block to the ground. The guy wire acts as the direct component for transmitting tensile force; its upper end connects to the guy wire, and its lower end, through a fixed connection with the connecting column, sequentially transmits the tensile force to the bearing plate, the fixed block, and the anchors, forming a complete force transmission chain. After installation, backfill soil is placed over the fixed block and the installation cavity, and the soil is compacted to ensure a tight bond between the fixed block and the surrounding soil. This combined structure of the fixed block and anchors significantly enhances the pull-out and lateral displacement resistance of the underground foundation. Furthermore, the backfill soil filling the installation cavity and covering the fixed block improves its resistance to overturning under harsh conditions such as strong winds and heavy rains, effectively avoiding the risks of settlement and pull-out failures.

[0023] Please see Figures 1 to 5The present application will now describe the guy bar used for guy wire connection. A guy bar for guy wire connection includes a fixing block 10, a bearing plate 20, a connecting post 30, an anchor 40, and a guy bar body 50. The fixing block 10 is buried underground. The fixing block 10 has an installation cavity 11 and a first through hole 12 at the bottom of the installation cavity 11. The bearing plate 20 is horizontally arranged and fixedly installed on the fixing block 10. The bearing plate 20 is located above the installation cavity 11 and has a second through hole 21. The connecting post 30 has a connecting hole 31 that extends axially and is coaxial with the second through hole 21. The anchor 40 passes through the installation cavity 11 and its lower end passes through the first through hole 12 to anchor the fixing block 10 to the ground. The upper end of the guy bar body 50 is used to connect with a guy wire, and the lower end passes through the connecting hole 31 and the second through hole 21 and is used to fix it to the connecting post 30.

[0024] The guy rod provided in this application, compared with the prior art, utilizes a fixed block 10 and anchor 40 to construct a solid underground bearing foundation. Combined with a bearing plate 20 and connecting column 30, it achieves a stable connection between the guy rod body 50 and the fixed block 10, ultimately ensuring the effective transmission of guy wire tension. The fixed block 10, as the core bearing component, is buried underground. Its internal installation cavity 11 provides space for the installation of the anchor 40 and also provides space for backfill soil. The first through hole 12 at the bottom provides a channel for the lower end extension of the anchor 40, ensuring that the anchor 40 can penetrate deep underground for anchoring. The horizontally positioned bearing plate 20 is fixed to the fixed block 10 and located above the installation cavity 11. Its second through hole 21 is coaxial with the axial connection hole 31 of the connecting column 30, providing precise positioning for the installation of the guy rod body 50 and avoiding uneven stress caused by installation deviations. Anchor 40 bears the main responsibility for resisting pull-out and lateral displacement. Through its structure penetrating the installation cavity 11 and extending deep into the ground, it firmly anchors the fixed block 10 to the ground. The guy rod body 50 serves as the direct component for transmitting tensile force; its upper end connects to the guy wire, and its lower end, through a fixed connection with the connecting column 30, sequentially transmits the tensile force to the bearing plate 20, the fixed block 10, and the anchor 40, forming a complete force transmission chain. After installation, backfill soil is placed over the fixed block 10 and the installation cavity 11, and the soil is compacted to ensure a tight bond between the fixed block 10 and the surrounding soil. In this way, the combined structure of the fixed block 10 and the anchor 40 significantly improves the pull-out and lateral displacement resistance of the underground fixed foundation. Furthermore, the backfill soil filling the installation cavity 11 and covering the fixed block 10 enhances its resistance to overturning under harsh environments such as strong winds and heavy rains, effectively avoiding the risks of settlement, pull-out, and other failures.

[0025] Finally, the pull wire is connected to the upper end of the pull rod body 50 using UT wire clamps and other hardware. The tension of the pull wire is adjusted to the design value using a tensioner and then locked. The upper end of the pull rod body 50 is provided with a connecting ring 51, and one end of the pull wire is connected to the connecting ring 51.

[0026] Please see Figures 1 to 5 As a specific embodiment of the pull rod for pull wire connection provided in this application, the fixing block 10 includes a base plate 13 and two side plates 14 respectively fixedly installed on both sides of the base plate 13, forming an installation cavity 11; a first through hole 12 is opened on the base plate 13, and the two ends of the bearing plate 20 are respectively fixedly connected to the two side plates 14; the base plate 13 and the two side plates 14 enclose an open installation cavity 11, preserving the installation space for the anchor 40. The first through hole 12 in the base plate 13 ensures that the anchor 40 is vertically stressed, and the fixing of the two ends of the bearing plate 20 to the side plates 14 forms a stable lateral support structure, preventing the bearing plate 20 from shifting under stress. The open installation cavity 11 facilitates the installation and position adjustment of the anchor 40, and is more suitable for complex foundation pit environments than a closed block; the rigid connection between the base plate 13 and the side plates 14 improves the overall deformation resistance of the fixing block 10, and the stable connection between the bearing plate 20 and the side plates 14 ensures that the tensile force is evenly transmitted to both sides.

[0027] Please see Figure 1 , Figure 3 and Figure 5 As a specific embodiment of the pull rod for pull wire connection provided in this application, support blocks 22 are fixed on the inner walls of both side plates 14, and the two ends of the bearing plate 20 are respectively supported and fixed on the two support blocks 22. By fixing the support blocks 22 on the inner walls of the side plates 14, precise support and installation benchmarks are provided for the bearing plate 20. The two ends of the bearing plate 20 are placed on the support blocks 22 for fixation, ensuring the installation level. The setting of the support blocks 22 eliminates the need for positioning and calibration steps of the bearing plate 20, improves installation efficiency, and at the same time disperses the force of the bearing plate 20 to the side plates 14, avoiding local stress concentration and further enhancing the overall load-bearing stability of the fixed block 10.

[0028] Please see Figure 1 , Figure 3 and Figure 5As a specific embodiment of the pull rod for pull cable connection provided in this application, the support block 22 has a through T-slot 23, and the lower end of the bearing plate 20 has a T-block 24 that slides into the T-slot 23. The T-slot 23 on the support block 22 and the T-block 24 at the lower end of the bearing plate 20 form a sliding fit, utilizing the anti-detachment characteristics of the T-shaped structure to achieve precise positioning and stable connection between the two, preventing the bearing plate 20 from shifting under force. During operation, the T-block 24 of the bearing plate 20 is aligned with the T-slot 23 of the support block 22 and pushed horizontally into place. After positioning, it is fixed with bolts or by welding. This method eliminates the need for repeated calibration during the installation of the bearing plate 20, significantly improving assembly efficiency. The T-shaped fit structure disperses vertical pressure and horizontal tension, preventing the bearing plate 20 from loosening or deforming.

[0029] Please see Figures 1 to 5 As a specific embodiment of the guy bar for guy wire connection provided in this application, two side plates 14 are symmetrically arranged on both sides of the base plate 13, and the included angle between the side plates 14 and the base plate 13 is an obtuse angle. This increases the contact area between the fixing block 10 and the surrounding soil, disperses the force, and enhances the resistance to lateral displacement. The symmetrical arrangement makes the fixing block 10 bear the force evenly, and the obtuse angle structure enhances the resistance of the side plates 14 to extrusion deformation compared to a right angle, improves the embedding effect with the soil, and significantly improves the pull-out resistance compared to traditional structures.

[0030] Please see Figure 1 , Figure 2 , Figure 4 As a specific embodiment of the guy rod for guy wire connection provided in this application, the bearing plate 20 is located in the middle of the mounting cavity 11. There are two first through holes 12 and two anchors 40, symmetrically arranged on both sides of the bearing plate 20. By placing the bearing plate 20 in the middle of the mounting cavity 11, and with the two first through holes 12 and anchors 40 symmetrically distributed on both sides, the force on the bearing plate 20 is evenly transmitted to the ground through the anchors 40, avoiding unilateral imbalance. The bearing plate 20 is installed in the middle of the mounting cavity 11 and aligned. Then, the two anchors 40 are inserted into the first through holes 12 on both sides, ensuring symmetry and penetration into the bearing layer. After backfilling and compaction, the connecting column 30 and the guy rod body 50 are installed sequentially. The centrally located bearing plate 20 ensures balanced force distribution, and the symmetrical arrangement of the two anchors 40 enhances pull-out resistance and lateral displacement resistance.

[0031] Please see Figure 1 and Figure 2As a specific embodiment of the pull rod for pull wire connection provided in this application, the outer surface of the anchor 40 is provided with an external thread section 41 and a threaded locking nut 42. The locking nut 42 is used to fix the anchor 40 to the fixing block 10. Through the cooperation of the external thread section 41 on the outer surface of the anchor 40 and the locking nut 42, a detachable and stable connection between the anchor 40 and the fixing block 10 is achieved, preventing the anchor 40 from loosening. During operation, the anchor 40 is first inserted into the mounting cavity 11 of the fixing block 10 and the first through hole 12 of the bottom plate 13, so that it penetrates deep into the underground bearing layer. Then, the locking nut 42 is screwed into the external thread section 41 until it is tightly attached to the bottom of the fixing block 10 and locked. The threaded engagement makes the anchor 40 more reliably fixed, facilitates installation, adjustment and subsequent disassembly and replacement. The locking nut 42 can counteract the loosening tendency of the anchor 40 under tension and improve pull-out stability.

[0032] Please see Figure 1 and Figure 2 As a specific embodiment of the pull rod for connecting pull wires provided in this application, the outer surface of the pull rod body 50 is provided with an external thread section 41 and two threaded locking nuts 42. The two locking nuts 42 are respectively located at the upper end of the connecting post 30 and the lower end of the bearing plate 20. The two locking nuts 42 are used to fix the pull rod body 50, the connecting post 30 and the bearing plate 20. Through the cooperation of the external thread section 41 of the pull rod body 50 and the two locking nuts 42, the pull rod body 50 is rigidly fixed to the connecting post 30 and the bearing plate 20 in a bidirectional clamping manner. The two nuts are respectively attached to the upper end of the connecting post 30 and the lower end of the bearing plate 20 to form a stable sandwich connection structure. During operation, first install the bearing plate 20 and connecting post 30 coaxially onto the fixed block 10. Then, insert the lower end of the pull rod body 50 into the connecting hole 31 of the connecting post 30 and the second through hole 21 of the bearing plate 20. Screw the first locking nut 42 into the lower end of the bearing plate 20 until it is tightly against the bearing plate 20. Next, screw the second locking nut 42 into the upper end of the connecting post 30. Tighten both nuts in both directions with a wrench to ensure that there is no relative looseness among the three. The double nut cooperation can counteract the loosening tendency caused by the force on the pull line, improving the pull resistance stability; the threaded connection facilitates precise adjustment of the height of the pull rod body 50 to adapt to different pull line angle requirements.

[0033] Please see Figure 5 As a specific embodiment of the guy bar for guy wire connection provided in this application, a plurality of extended stiffening plates 15 are provided on the outer side of the fixed block 10. The extended stiffening plates 15 increase the contact area and frictional resistance with the surrounding soil, and strengthen the embedding effect of the fixed block 10, so that the extended stiffening plates 15 can distribute the force of the fixed block 10 to a larger area of ​​soil, improve the pull-out resistance, and effectively suppress lateral displacement; and the extended stiffening plates 15 can enhance the rigidity of the fixed block 10 itself.

[0034] Please see Figure 3 As a specific embodiment of the guy bar for guy wire connection provided in this application, the outer wall of the fixing block 10 is provided with a flow guiding through hole 16 that communicates with multiple mounting cavities 11. The flow guiding through hole 16 connects the mounting cavities 11 to the external environment, providing a channel for concrete pouring. The concrete inside and outside the mounting cavities 11 forms a continuous whole, strengthening the load-bearing foundation of the fixing block 10. Concrete is poured into the pit until it fills the mounting cavities 11 through the flow guiding through hole 16. The integral structure formed by the concrete through the flow guiding through hole 16 enhances the bonding force between the fixing block 10 and the foundation, prevents voids in the mounting cavities 11, and ensures uniform force transmission.

[0035] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
