Technical Field
[0001] This invention relates to the field of crossarm technology, and more particularly to an assembled crossarm structure. Background Technology
[0002] Crossarms are a crucial component of power towers, serving not only to install insulators and fittings but also to support conductors. Existing technologies employ assembly-type crossarm structures, which reduce the volume of the entire crossarm during transport to heights and lower the difficulty of handling for workers. However, this assembly process is extremely complex, often requiring workers to use various tools such as wrenches to reach the heights. Working at heights requires not only avoiding cumbersome procedures but also minimizing the use of excessive tools to prevent safety hazards such as tools falling. Therefore, ensuring rapid and stable installation of crossarm structures at heights without the need for auxiliary tools, while minimizing safety risks for workers, is a problem that needs to be solved by those in the field. Summary of the Invention

[0036] Crossarms are a crucial component of power towers, serving not only to install insulators and fittings but also to support conductors. Existing technologies employ assembly-type crossarm structures, which reduce the volume of the entire crossarm during transport to heights and lower the difficulty of handling for workers. However, this assembly process is extremely complex, often requiring workers to use various tools such as wrenches to reach the heights. Working at heights requires not only avoiding cumbersome procedures but also minimizing the use of excessive tools to prevent safety hazards such as tools falling. Therefore, ensuring rapid and stable installation of crossarm structures at heights without the need for auxiliary tools, while minimizing safety risks for workers, is a problem that needs to be solved by those in the field.
[0037] Example 1
[0038] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.
[0039] like Figures 1-7 As shown, this embodiment provides an assembled crossarm structure that can be clamped to the outside of a utility pole. The assembled crossarm structure includes two parallel crossarm bodies 100, a plurality of insulators 200 disposed on the crossarm bodies 100, a connecting ring 20, a connecting device 30, a folding plate 40, and a locking device 50. The connecting ring 20 is vertically inserted through the two crossarm bodies 100. One end of the connecting ring 20 is connected to the connecting device 30, which is disposed on the outside of one crossarm body 100. The other end of the connecting ring 20 is connected to the folding plate 40, which is disposed on the outside of the other crossarm body 100. The distance between the two crossarm bodies 100 can be adjusted by the folding plate 40. The locking device 50 is used to lock the folding plate 40 onto the crossarm body 100.
[0040] Specifically, in this embodiment, the arrangement of two crossarm bodies 100 ensures the stable installation of the insulator 200 and improves the wind resistance of the entire structure in strong winds, preventing damage from strong winds. Simultaneously, the connecting ring 20, connecting device 30, folding plate 40, and locking device 50 can be assembled onto the crossarm body 100, effectively reducing the difficulty of transporting the entire structure at heights and decreasing its transport volume. Furthermore, the connecting ring 20 is connected to the connecting device 30 and the folding plate 40 respectively, and the connecting device 30 and the folding plate 40 are located on the two crossarm bodies 100, thereby achieving a stable connection between the two crossarm bodies 100 and ensuring the stable installation of the entire structure on the utility pole. Specifically, the distance between the two crossarm bodies 100 can be adjusted by the folding plate 40, thus adapting to utility poles of different sizes and expanding the applicability of the entire structure. Furthermore, the locking device 50 can lock the folding plate 40 onto the crossarm body 100. After the distance between the two crossarm bodies 100 is adjusted, the locking device 50 can lock the folding plate 40 to fix the distance between the two crossarm bodies 100, thereby ensuring the stable installation of the crossarm body 100 on the utility pole. In addition, in this embodiment, the crossarm body 100 can be installed on the utility pole by the cooperation of the connecting ring 20, connecting device 30, folding plate 40, and locking device 50, eliminating the need for auxiliary tools. This not only improves the installation efficiency of the entire structure but also reduces the difficulty of working at heights and minimizes safety risks for workers during the operation.
[0041] The specific structure of the assembled crossarm structure in this embodiment will be described below.
[0042] like Figures 1-4As shown, the assembled crossarm structure in this embodiment includes a crossarm body 100, insulators 200, a plug-in assembly 10, a connecting ring 20, a connecting device 30, a folding plate 40, a locking device 50, and a supporting arc plate 60. Optionally, in this embodiment, two crossarm bodies 100 are provided, both of which are concave structures, and several insulators 200 are spaced apart on the upper and lower sides of each crossarm body 100. In this embodiment, the two crossarm bodies 100 are placed parallel and spaced apart. In actual use, the utility pole is located between the two crossarm bodies 100 to facilitate the clamping of the utility pole. For example, the insulators 200 are porcelain insulators. Further, the plug-in assembly 10 is disposed on the inner side of the crossarm body 100 to achieve stable installation of the two crossarm bodies 100 and ensure their parallel placement. Optionally, the connecting ring 20 is disposed perpendicular to the two crossarm bodies 100, and can pass through both crossarm bodies 100 simultaneously and extend out of both crossarm bodies 100. Specifically, the connecting device 30 is connected to one end of the connecting ring 20 and is disposed on the outside of one crossarm body 100. The folding plate 40 is connected to the other end of the connecting ring 20, and the other end of the folding plate 40 is connected to the locking device 50. Both the folding plate 40 and the locking device 50 are disposed on the outside of the other crossarm body 100. Optionally, in this embodiment, the distance between the two crossarm bodies 100 can be adjusted by the folding plate 40 to ensure that the two crossarm bodies 100 are clamped on the outside of the utility pole, and it is applicable to utility poles of different diameters, thus expanding its applicability. Further, in this embodiment, the locking device 50 can lock the folding plate 40 onto the crossarm body 100 to ensure that the position of the folding plate 40 does not change, thereby keeping the distance between the two crossarm bodies 100 constant and ensuring the stable installation of the entire structure on the outside of the utility pole. Further, the supporting arc plate 60 is disposed on the inside of the crossarm body 100 for clamping the utility pole.
[0043] Combination Figures 1-5 and Figure 7 As shown, specifically, in this embodiment, a reinforcing strip 101 is provided on the inner side of the crossbeam body 100, and a through groove 102 is provided through the crossbeam body 100. Figure 4 As shown, optionally, each crossbeam body 100 has symmetrically arranged reinforcing strips 101 on its inner upper and lower sides to ensure the mechanical strength of the crossbeam body 100 and prevent deformation during installation and use. Furthermore, each of the two crossbeam bodies 100 has a through groove 102, and when the two crossbeam bodies 100 are placed parallel, the through groove 102 is also correspondingly provided, so that the connecting ring 20 can simultaneously pass through the through grooves 102 on both crossbeam bodies 100, achieving a stable connection with the connecting device 30 and the folding plate 40.
[0044] like Figure 4As shown, optionally, the plug-in assembly 10 includes a plug-in cylinder 11 and a plug-in rod 12 that can be plugged into each other. Specifically, one of the two crossarm bodies 100 is provided with a plug-in rod 12, and the other is provided with a plug-in cylinder 11. Thus, the plug-in rod 12 and the plug-in cylinder 11 can be plugged into each other to achieve a detachable connection between the two crossarm bodies 100. Optionally, the plug-in assembly 10 is disposed on the inner side of the crossarm body 100, and both the plug-in rod 12 and the plug-in cylinder 11 are perpendicular to the crossarm body 100. This ensures the parallelism between the two crossarm bodies 100 after they are plugged in, restricts the movement direction and position of the two crossarm bodies 100, and effectively improves the wind resistance of the entire structure in strong wind conditions. Exemplarily, in this embodiment, four sets of plug-in assemblies 10 are provided, and the four sets of plug-in assemblies 10 are installed parallel and spaced apart. In other embodiments, different numbers and different spacings of plug-in assemblies 10 can be provided as needed, which will not be elaborated here.
[0045] Furthermore, in this embodiment, two connecting rings 20 are provided. The two connecting rings 20 are parallel and spaced apart, and both are perpendicular to the crossarm body 100. Correspondingly, each crossarm body 100 is provided with two through slots 102, and the two connecting rings 20 respectively pass through the corresponding through slots 102 on the two crossarm bodies 100 and extend out of the outer side of the crossarm body 100. Specifically, in this embodiment, one connecting device 30 is provided, and the two connecting rings 20 are detachably connected to the connecting device 30. Two folding plates 40 and two locking devices 50 are provided. The other end of each connecting ring 20 is connected to a folding plate 40, and the end of each folding plate 40 away from the connecting ring 20 can be locked to the crossarm body 100 by the locking device 50. Exemplarily, the two connecting rings 20, the two folding plates 40, and the two locking devices 50 are all symmetrically arranged. Optionally, in this embodiment, the connecting ring 20 is rotatably connected to the folding plate 40. Thus, during installation, the folding plate 40 can be placed on the outside of one crossbeam body 100, and then the connecting ring 20 is sequentially passed through the through slots 102 of two crossbeam bodies 100 to extend out of the outside of another crossbeam body 100 and engage with the connecting device 30. By adjusting the folding plate 40, the rotation angle between the folding plate 40 and the connecting ring 20 can be changed to adjust the distance between the two crossbeam bodies 100.
[0046] Combination Figure 5 and Figure 7 As shown, the connecting device 30 includes a connecting plate 31, an adjusting assembly 32, and a guiding assembly 33. The connecting plate 31 has a slot 311. The adjusting assembly 32 includes a threaded cylinder 321, a screw 322, and a rotating handle 323. The guiding assembly 33 includes a sleeve 331 and a guide rod 332. Figure 7As shown, the connecting plate 31 is a square plate, and slots 311 are symmetrically arranged on both sides of the connecting plate 31. In this embodiment, the slots 311 are V-shaped slots, and the connecting ring 20 can be fitted into the slots 311, thereby limiting the connecting ring 20 to the connecting plate 31, realizing quick assembly and disassembly between the connecting ring 20 and the connecting device 30, ensuring the stability of the connection between the two, and preventing the connecting ring 20 from falling off the connecting plate 31.
[0047] Optionally, the connecting plate 31 is tunably connected to the crossarm body 100 via the adjusting component 32, thereby allowing adjustment of the distance between the connecting plate 31 and the crossarm body 100, and consequently, the position of the connecting ring 20. By combining the adjustment of the connecting ring 20 and the folding plate 40, the adjustment range of the distance between the two crossarm bodies 100 can be expanded or reduced, making it suitable for the installation of utility poles of more sizes.
[0048] Combination Figure 5 and Figure 7 As shown, specifically, in this embodiment, one end of the screw 322 in the adjusting assembly 32 is located on the outside of the crossarm body 100. In this embodiment, the screw 322 is rotatably connected to the crossarm body 100, and the crossarm body 100 does not rotate synchronously with the screw 322. Further, the other end of the screw 322 is connected to the rotating handle 323, and the threaded cylinder 321 is screwed to the outside of the screw 322 and fixed to the connecting plate 31. Thus, by rotating the handle 323, the position of the threaded cylinder 321 on the screw 322 can be adjusted, thereby changing the specific distance between the connecting plate 31 and the crossarm body 100. Exemplarily, the rotating handle 323 includes a fixed block and several short rods, which are evenly arranged around the axis of the fixed block in the circumference of the fixed block. Optionally, in this embodiment, three short rods are provided, which are evenly arranged around the circumference of the fixed block, thereby facilitating operation by the operator and improving the disassembly and assembly efficiency of the entire structure.
[0049] Furthermore, in this embodiment, the guide rod 332 in the guide assembly 33 passes through the connecting plate 31 and is fixed to the outside of the crossbeam body 100. The sleeve 331 is sleeved on the outside of the guide rod 332 and fixed to the connecting plate 31. Thus, the sleeve 331 is slidably disposed on the outside of the guide rod 332. During the adjustment process of the adjustment assembly 32, the connecting plate 31 moves up and down relative to the screw 322 under the drive of the threaded sleeve 321, and at the same time drives the sleeve 331 to move up and down on the outside of the guide rod 332, thereby realizing the guiding effect of the guide assembly 33 and ensuring the stability of the connecting plate 31 during movement. Specifically, the guide rod 332 and the screw 322 are arranged parallel to each other, and both are arranged perpendicular to the connecting plate 31, thereby ensuring smooth and uninterrupted movement of the connecting plate 31 when it moves up and down. Optionally, a limiting block is provided on the end of the guide rod 332 away from the connecting plate 31. The outer diameter of the limiting block is larger than the outer diameter of the sleeve 331, thereby limiting the movement of the connecting plate 31 and preventing the connecting plate 31 from causing the sleeve 331 to detach from the guide rod 332. In this embodiment, two sets of guide components 33 are provided, and the two sets of guide components 33 are symmetrically arranged on both sides of the adjusting component 32. This allows the two ends of the connecting plate 31 to be guided when the connecting plate 31 moves up and down, ensuring its movement stability. In other embodiments, the number of guide components 33 can be set as needed.
[0050] Combination Figure 1 and Figure 7 As shown, in this embodiment, the folding plate 40 includes a sliding portion and a bending portion. Optionally, the sliding portion is slidably disposed on the outside of the crossbeam body 100, and the bending portion is disposed at an angle to the sliding portion. One end of the bending portion is connected to the sliding portion, and the other end is connected to the connecting ring 20, thereby realizing the connection between the folding plate 40 and the connecting ring 20. Optionally, the bending portion and the sliding portion are configured to be rotatably connected, thereby realizing multi-angle settings between the bending portion and the sliding portion. Specifically, the connecting ring 20 is rotatably connected to the bending portion, so that when the sliding portion slides on the crossbeam body 100, the connecting ring 20 can adapt its angle to the bending portion accordingly.
[0051] Combination Figure 6 As shown, the sliding part is provided with a limiting groove 401 and anti-slip strips 402. Specifically, the limiting groove 401 is provided through the side facing the locking device 50, so that the locking device 50 can press against the bottom of the limiting groove 401 to lock the sliding part onto the crossarm body 100. Furthermore, a number of anti-slip strips 402 are provided parallel and at equal intervals on the sliding part, so that the operator can better slide the folding plate 40 on the crossarm body 100 through the anti-slip strips 402, thereby pushing the crossarm body 100 under the action of the connecting ring 20 to change the relative distance between the two crossarm bodies 100, and thus better clamping it to the outside of the utility pole.
[0052] Combination Figure 1 and Figure 6 As shown, in this embodiment, the locking device 50 includes a locking component 51, an adjusting block 52, and a locking block 53. The locking component 51 includes an elastic piece 511 and a fixing plate 512. The adjusting block 52 is provided with an adjusting lever 521 and a positioning groove 522. Optionally, the locking component 51 is disposed on the crossarm body 100 and is used to limit the adjusting block 52. Specifically, the fixing plate 512 in the locking component 51 is fixedly connected to the crossarm body 100 by screws. Further, one end of the fixing plate 512 is connected to the elastic piece 511. The elastic piece 511 is perpendicular to the fixing plate 512, and the side of the elastic piece 511 facing the adjusting block 52 is provided with a limiting protrusion, thereby limiting and fixing the position of the adjusting block 52 and locking the position of the adjusting block 52. Exemplarily, the elastic piece 511 has a certain elasticity to avoid interference with the adjustment process of the adjusting block 52, while being able to be tightly locked to the outside of the adjusting block 52.
[0053] Optionally, the adjusting block 52 is rotatably mounted on the crossarm body 100, and the adjusting block 52 is provided with an adjusting lever 521, which allows the operator to quickly rotate the adjusting block 52 by moving the adjusting lever 521. Further, a plurality of positioning grooves 522 are provided on the circumferential outer side of the adjusting block 52, and the limiting protrusion on the elastic piece 511 in the locking assembly 51 can engage with the positioning grooves 522 on the outer side of the adjusting block 52, thereby locking the position of the adjusting block 52. Further, a locking block 53 is connected to the adjusting block 52, and the locking block 53 can press against the bottom of the limiting groove 401 to lock the position of the folding plate 40 on the crossarm body 100. Similarly, the locking block 53 is connected to the adjusting block 52 and rotates together with it on the crossarm body 100. Thus, during the rotation of the adjusting block 52, the locking block 53 can move synchronously with it to press against the limiting plate 40 at the bottom of the limiting groove 401, or move away from the limiting groove 401 to facilitate position adjustment of the plate 40 on the crossarm body 100. Furthermore, after the position of the plate 40 is determined, the locking block 53 is rotated into the limiting groove 401 by the adjusting block 52, and then the locking assembly 51 engages with the outside of the adjusting block 52 to lock the positions of the adjusting block 52 and the locking block 53, thereby fixing the plate 40 and ensuring the stability of the entire device connection.
[0054] like Figure 7 As shown, in this embodiment, two supporting arc plates 60 are provided, and one supporting arc plate 60 is provided on each crossarm body 100. Specifically, the supporting arc plates 60 are located on the inner side of the crossarm body 100, and the two supporting arc plates 60 are arranged facing each other. Optionally, the supporting arc plates 60 are provided with arc-shaped surfaces, so that they can abut against the outer side of the utility pole, ensuring the stable installation of the entire structure on the utility pole. For example, an elastic pad 601 is installed on the arc-shaped surface, thereby increasing the friction between the entire structure and the utility pole, reducing slippage, and improving installation stability.
[0055] Working principle: First, several insulators 200 are installed on the corresponding crossarm bodies 100, and the two crossarm bodies 100 are placed parallel and symmetrically, with the utility pole positioned between the two crossarm bodies 100. Then, the other end of the connecting ring 20 connected by the folding plate 40 is sequentially inserted through the through slots 102 of the two crossarm bodies 100 and extends to the outside of the crossarm bodies 100, with the utility pole positioned between the two connecting rings 20. Then, the distance between the connecting plate 31 and the crossarm body 100 is adjusted by rotating the handle 323 to accommodate the extended position of the connecting ring 20. Finally, the two connecting rings 20 are respectively secured. The connecting ring 20 is stably installed on the crossarm body 100 by means of two slots 311 on the connecting plate 31; then, the folding plate 40 is pushed to slide on the crossarm body 100 by the anti-slip strip 402 until the supporting arc plate 60 is tightly fitted on the outside of the utility pole; finally, the adjusting block 52 is rotated by the adjusting lever 521 until the locking block 53 presses against the limiting groove 401 of the folding plate 40 to lock the position of the folding plate 40, and the position of the adjusting block 52 is finely adjusted so that the limiting protrusion of the elastic piece 511 is engaged in the positioning groove 522, thereby locking the position of the adjusting block 52 and thus locking the position of the folding plate 40. Therefore, the entire operation process is simple and quick, and no additional tools are required, making it convenient for operators to assemble and install.
[0056] Example 2
[0057] This embodiment provides an assembled crossbeam structure, wherein the same or corresponding components as in Embodiment 1 are represented by the corresponding reference numerals in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The difference is that in this embodiment, the connecting ring 20 is detachably connected to the folding plate 40. Specifically, the connecting ring 20 is provided with a closed end and an open end. The closed end can be snapped into the slot 311, and the open end can be inserted into the end of the bent portion of the folding plate 40 away from the sliding portion. For example, the end of the bent portion away from the sliding portion is provided with an installation port, and installation cylinders are provided on both sides of the installation port. Optionally, the connecting ring 20 is configured as a U-shaped structure, with short insertion rods extending backwards on both sides of its open end. The short insertion rods can be inserted into the installation cylinders, thereby realizing the detachable connection between the connecting ring 20 and the sliding portion, and ensuring the rotational connection between the connecting ring 20 and the folding plate 40, thus facilitating the storage, maintenance, and quick installation of the entire structure.
