Abstract
Description
Technical Field
[0001] This invention relates to the field of power line installation equipment technology, and in particular to an adjustable, multi-adaptive crossarm cable support. Background Technology
[0002] Four-wire crossarm, also known as four-wire crossarm, is a support component on power poles that simultaneously supports four conductors. Its core feature is that it is designed specifically for "three-phase four-wire" power distribution systems, and can support three live wires and one neutral wire at a time, thus forming a complete power distribution circuit and providing a guarantee for power and lighting in our daily lives. It is the most common and representative type of crossarm in urban and rural power distribution networks.
[0003] Traditional crossarm supports are mostly fixed structures, such as four-wire crossarm supports and L-shaped crossarm supports. Due to limitations in the installation environment and wiring direction, one type of support can usually only be installed in one working environment, which makes the scope of application of the support narrow. Different models of supports will lead to an increase in production and R&D costs. Therefore, the fixed structure of traditional crossarms cannot adapt to multiple environments, resulting in functional shortcomings in actual use. Summary of the Invention
[0004] This invention discloses an adjustable multi-adaptive crossarm cable bracket, which aims to solve the technical problem that existing four-wire brackets cannot be structurally adapted and adjusted according to the actual installation location, resulting in functional shortcomings.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable multi-adaptive crossarm cable support includes several insulators. The bottom of each insulator is provided with a fixing mechanism that provides installation points. The fixing mechanism includes two symmetrically connected crossarms, and a bracket can be detachably installed at the end of each crossarm.
[0007] The fixing mechanism is internally equipped with a connecting mechanism for connecting the insulators. The connecting mechanism includes several main flaps rotatably installed inside the crossbeam. Each main flap has a long slot inside. The insulator is engaged with the side of the main flap through the long slot. The side of the main flap is connected to a secondary flap. The secondary flap has a short slot inside. A bracket is welded and fixed to the top side of the crossbeam. When the fixing mechanism is installed on the wall, the tops of several insulators are sequentially engaged and fixed to the side of the secondary flap through adjacent short slots. At the same time, the end of one insulator located on the side is engaged and fixed inside the bracket.
[0008] The fixing mechanism, in conjunction with the connecting mechanism, is used to adjust the angle of the insulator, thereby adapting it for installation in different usage environments.
[0009] By improving the structure of the basic four-wire crossarm by incorporating a fixing mechanism, which works in conjunction with a connecting mechanism to secure the insulator, the insulator can be adapted for installation in different environments by changing the placement and folding angles of the fixing and connecting mechanisms. Under normal conditions, the fixing and connecting mechanisms drive the insulator to be installed horizontally on the ground. When adapting to narrow terrain such as alleyways, the connecting mechanism folds to work with the fixing mechanism to fix the insulator to the wall. When adapting to corners, the fixing mechanism folds to work with the connecting mechanism to fix the insulator to the corner. This allows a single four-wire crossarm to adapt to different operating environments, significantly improving the functionality and operational reliability of traditional equipment.
[0010] In a preferred embodiment, when the crossbar is folded into a right angle, two threaded rods are added to the side of the crossbar, and the two threaded rods are connected to a vertical frame, which is horizontally fixed to the wall by rivets.
[0011] By setting the integrated support structure of the basic four-wire crossarm as two separate crossarm structures, and additional threaded rods and uprights can be installed on the sides of the crossarms; under normal conditions, the two horizontally distributed crossarms, together with the support and connecting mechanism, drive the insulator to be installed horizontally on the ground; when adapted to the corner, the two crossarms fold up to be distributed at a right angle, together with the additional threaded rods, uprights and connecting mechanism, to fix the insulator in the corner, thereby realizing multiple functions and improving the functionality of traditional equipment.
[0012] In a preferred embodiment, a slide plate is slidably mounted inside the crossbeam, and a pair of buttons are fixed to the top of each slide plate. When the fixing mechanism is installed on the ground, each button slides into the interior of one of the short slots.
[0013] By further incorporating a main flap and a secondary flap structure that are rotatably installed inside the split crossframe, the two horizontally distributed crossframes, along with the support frame and the main flap and secondary flap, which are limited by the button on the top of the sliding plate, drive the insulator to be horizontally installed on the ground under normal conditions. When adapting to narrow terrain such as alleyways, the main flap and secondary flap, which lose their button limit, fold over, causing the insulator to change its angle, and then, together with the crossframe and support frame, fix the insulator to the wall. When adapting to corners, the two crossframes, which fold over and are distributed at right angles, along with the additional threaded rod and upright frame, and the main flap and secondary flap, which are limited by the button, fix the insulator to the corner, thereby achieving multiple functions and improving the functionality of traditional equipment.
[0014] In a preferred embodiment, the top of the insulator is threaded with a nut, which, when the fixing mechanism is installed on the wall, presses against the adjacent short slot and the interior of the retainer.
[0015] By setting a threaded nut structure on the top of the insulator, when adapting to narrow terrain such as tunnels, the main flap and the auxiliary flap, which lose the button limit, fold and drive the insulator to change its angle. By using the nut in conjunction with the short slot and the bracket structure inside the auxiliary flap, several insulators can be fixed in sequence, thereby further improving the functionality and operational completeness of the equipment.
[0016] As can be seen from the above, the present invention has the following technical effects.
[0017] 1. By setting the integrated support structure of the basic four-wire crossarm as two separate crossarm structures, and further setting the main flap and auxiliary flap structures that are rotatably installed inside the crossarm, under normal conditions, the two horizontally distributed crossarms, together with the support and the main flap and auxiliary flap limited by the button on the top of the sliding plate, drive the insulator to be installed horizontally on the ground.
[0018] 2. When adapting to narrow terrains such as alleyways, the main flap and auxiliary flap, which lose their button limit, fold and cause the insulator to change its angle. Then, in conjunction with the cross frame and bracket, the insulator is fixed to the wall. This is suitable for wiring requirements in different usage scenarios.
[0019] 3. When adapting to the corner of the wall, the two crossarms that fold at right angles, together with the additional threaded rods and uprights, as well as the main flap and auxiliary flaps with button-locking limit, fix the insulator in the corner, thereby enabling the four-wire crossarm of this application to adapt to different usage environments and greatly improve the functionality and operational completeness of traditional equipment.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0033] The adjustable multi-adaptive crossarm cable bracket disclosed in this invention is mainly used in various environments for adapting and fixing wires and cables.
[0034] Reference Figures 1 to 11 An adjustable multi-adaptive crossarm cable support includes several insulators 1. The bottom of the insulator 1 is provided with a fixing mechanism 2 that provides installation points. The fixing mechanism 2 includes two crossarms 201 that are symmetrically connected. Each crossarm 201 has a bracket 202 that can be detachably installed at its end.
[0035] The fixing mechanism 2 is equipped with a connecting mechanism 3 for connecting insulators 1. The connecting mechanism 3 includes several main flaps 301 rotatably installed inside the cross frame 201. Each main flap 301 has a long slot 302 inside. The insulator 1 is engaged with the side of the main flap 301 through the long slot 302. The side of the main flap 301 is connected to a secondary flap 303. The secondary flap 303 has a short slot 304 inside. A bracket 307 is welded and fixed to the top side of a cross frame 201. When the fixing mechanism 2 is installed on the wall, the tops of several insulators 1 are engaged and fixed to the side of the secondary flap 303 through adjacent short slots 304. At the same time, the end of an insulator 1 located on the side is engaged and fixed to the inside of the bracket 307.
[0036] The crossbeam 201 can be installed vertically or horizontally with the insulator 1. The fixing mechanism 2 and the connecting mechanism 3 are used to adjust the angle of the insulator 1, so as to adapt to different usage environments.
[0037] In this embodiment: the device has three working modes, specifically: when the device is used in a flat and open environment, the worker installs the fixing mechanism 2, which is in its initial state, on the ground using expansion bolts, and then installs several insulators 1 sequentially into the connecting mechanism 3, and locks the connecting mechanism 3; when the device is used in narrow terrain such as tunnels, the worker first installs several insulators 1 sequentially into the connecting mechanism 3, then flips the connecting mechanism 3 to one side, causing the connecting mechanism 3 to change the orientation of the insulators 1 and lock them in place. Afterwards, the worker lifts the entire fixing mechanism 2 and installs it onto the tunnel wall, as shown in the attached figure. Figure 2 As shown; when this equipment is used in corners or other terrain features, the worker first folds the fixing mechanism 2 so that it forms a right-angle structure. Then, the two insulators 1 are installed into the connecting mechanism 3 at the top of the fixing mechanism 2. After that, the connecting mechanism 3 is locked. The worker then lifts the entire fixing mechanism 2 and installs it onto the connecting frame that has been pre-fixed at the corner. The specific state is shown in the attached figure. Figure 4 As shown.
[0038] Reference Figures 1 to 2 , Figures 4 to 7 In a preferred embodiment, when the crossbar 201 is folded into a right angle, two threaded rods 203 are added to the side of the crossbar 201. The two threaded rods 203 are connected to a vertical frame 204, which is horizontally fixed to the wall by rivets.
[0039] Under normal conditions, the two crossbeams 201 are horizontally distributed. When this equipment is used in a flat and open environment, the worker installs the bracket 202 at the bottom of the crossbeam 201 onto the ground using expansion bolts. At the same time, several insulators 1 are sequentially installed into the connecting mechanism 3, and the connecting mechanism 3 is locked. When this equipment is used in narrow terrain such as tunnels, the worker first installs several insulators 1 into the connecting mechanism 3, then flips the connecting mechanism 3 to one side, causing the connecting mechanism 3 to change the orientation of the insulators 1 and lock them in place. Afterward, the worker lifts the entire crossbeam 201 and installs the bracket 202 onto the tunnel wall using expansion bolts. The specific configuration is shown in the attached figure. Figure 2 As shown; when this equipment is used in corners or other similar terrain, the worker first folds the crossbeam 201 so that it forms a right-angle structure. Then, the two insulators 1 are installed into the connecting mechanism 3 at the top of one crossbeam 201, and the threaded rod 203 is installed into the connecting mechanism 3 inside the other crossbeam 201. After that, the connecting mechanism 3 is locked, and the worker installs the entire unit at the corner of the wall. The specific configuration is shown in the attached figure. Figure 4 As shown.
[0040] Among them, such as Figure 11 As shown, the crossbeam 201 can be folded into a right angle to install the insulator 1. A hinge 205 is rotatably installed between the two crossbeams 201. The hinge 205 includes a hinge shaft 2051 rotatably disposed between the two crossbeams 201. A locking bolt 2052 is provided at the end of the hinge shaft 2051. After the worker completes the folding of the crossbeam 201, he tightens the locking bolt 2052, so that the locking bolt 2052 is tightly attached to the two crossbeams 201, thus completing the fixation of the crossbeam 201. A chamfer 2011 is provided at one end of the two crossbeams 201 near the hinge 205. The chamfer 2011 is used to facilitate the folding and alignment of the two crossbeams 201.
[0041] Reference Figures 1 to 8 In a preferred embodiment, a slide plate 305 is slidably mounted inside the crossbar 201. Each slide plate 305 has a pair of buttons 306 fixed to its top. When the fixing mechanism 2 is installed on the ground, each button 306 is slidably engaged inside a short slot 304.
[0042] Under normal conditions, the two crossbeams 201 are horizontally distributed. When this equipment is used in a flat and open environment, the worker uses expansion bolts to install the bracket 202 located at the bottom of the crossbeam 201 onto the ground. At the same time, the main flip plate 301 is flipped upward to expose the long slot 302. Then, the bottom of the insulator 1 is pressed and installed into the long slot 302. This process is repeated until several insulators 1 are installed into the main flip plate 301. After that, the main flip plates 301 are flipped back to their original positions and the sliding plate 305 is moved, causing the button 306 to slide and engage in the auxiliary flip plate 303. The short slot 304 of the main frame is used to lock the connecting mechanism 3. When this equipment is used in narrow terrain such as tunnels, the process is as described above. In this case, the worker first installs several insulators 1 into the inside of the connecting mechanism 3 in sequence, and then flips the main flap 301 to one side. This causes the main flap 301 to change the orientation of the insulators 1. At the same time, the end of the insulator 1 will be locked into the short slot 304 inside the adjacent secondary flap 303. After that, the worker lifts the entire cross frame 201 and installs the bracket 202 onto the tunnel wall using expansion bolts. The specific state is shown in the attached figure. Figure 2 As shown; when this equipment is used in corners or other terrain features, the worker first folds the crossbeam 201 so that it forms a right-angle structure. Then, the two insulators 1 are installed into the connecting mechanism 3 at the top of one crossbeam 201 according to the above steps. Next, the sliding plate 305 is moved so that the button 306 slides and engages in the short slot 304 inside the auxiliary flip plate 303, thus locking the main flip plate 301 and preventing the insulators 1 from falling off. After that, the threaded rod 203 is slidably installed into the long slot 302 of the main flip plate 301 inside the other crossbeam 201. The worker then installs the entire unit at the corner of the wall using the upright frame 204. The specific configuration is shown in the attached figure. Figure 4 As shown.
[0043] Among them, a number of symmetrically distributed connecting plates 308 are fixedly connected between the main flap 301 and the auxiliary flap 303.
[0044] Specifically, a resistance-increasing component 309 is fixedly installed on the side of the slide plate 305. The resistance-increasing component 309 is distributed on the outside of the cross frame 201. A bolt 310 is threaded on the side of the resistance-increasing component 309. The bolt 310 presses against the outside of the cross frame 201. A sliding groove 311 is opened through the side of the cross frame 201. The slide plate 305 passes through the inside of the sliding groove 311 and is fixedly connected to the resistance-increasing component 309. In summary, the specific locking steps of the connecting mechanism 3 are as follows: The worker moves the resistance-increasing component 309 to drive the slide plate 305 to move along the inside of the sliding groove 311, so that the button 306 slides and engages in the short slot 304 inside the secondary flip plate 303, thus restricting the main flip plate 301. At this time, the main flip plate 301 cannot rotate. Finally, by rotating the bolt 310, the bolt 310 presses against the outside of the cross frame 201, thereby locking the slide plate 305. Thus, the locking work of the connecting mechanism 3 is completed.
[0045] Reference Figures 1 to 5 , Figure 7 In a preferred embodiment, the top of the insulator 1 is threaded with a nut 101. When the fixing mechanism 2 is installed on the wall, the nut 101 on the top of the insulator 1 is pressed and engaged in the adjacent short slot 304, and the end of the insulator 1 closest to the slot 307 will be engaged in the interior of the slot 307. At this time, the worker can tighten each nut 101 in sequence.
[0046] In summary, this equipment has three working modes, as detailed below;
[0047] When this equipment is used in a flat and open environment, the worker uses expansion bolts to install the bracket 202 at the bottom of the crossbeam 201 onto the ground. Simultaneously, the main flip plate 301 is flipped upwards to expose the long slot 302. The bottom of the insulator 1 is then pressed into the long slot 302. This process is repeated until several insulators 1 are installed into the main flip plate 301. Afterwards, the main flip plates 301 are flipped back to their original positions, and the sliding plate 305 is moved, causing the button 306 to slide and engage in the short slot 304 inside the auxiliary flip plate 303. The bolt 310 is then tightened to lock the sliding plate 305 and the main flip plate 301. At this point, the main flip plate 301 cannot rotate around its axis, and the insulator 1 cannot detach from the main flip plate 301. The equipment can then be horizontally installed on a flat surface using the bracket 202. See attached diagram for details. Figure 1 and attached Figure 5 As shown;
[0048] When this equipment is used in narrow terrain such as tunnels, the process is as described above. First, the worker installs several insulators 1 with the main flap 301. Then, the main flap 301 is rotated 90 degrees to one side, causing the main flap 301 to change the orientation of the insulators 1. Simultaneously, the end of the insulator 1 will engage in the short slot 304 inside the adjacent auxiliary flap 303, and the end of the insulator 1 closest to the mounting base 307 will engage inside the mounting base 307. The worker then tightens each nut 101 sequentially to lock it in place. Afterwards, the worker lifts the entire crossbeam 201 and installs the bracket 202 onto the tunnel wall using expansion bolts. The specific details are shown in the attached diagram. Figure 2 and attached Figure 3 As shown;
[0049] When this equipment is used in corners or other similar terrain, the worker first folds the crossbeam 201 so that it forms a right-angle structure and tightens the hinge 205 for fixation. Then, the two insulators 1 are installed on the main flap 301 at the top of one crossbeam 201 according to the above steps. Next, the threaded rod 203 is slidably installed into the long slot 302 of the main flap 301 inside the other crossbeam 201. Then, the threaded rod 203 is locked to the upright 204 using a nut. The worker then installs the entire unit at the corner of the wall via the upright 204. The specific configuration is shown in the attached figure. Figure 4 As shown.
[0050] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
