Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable support technology, specifically an adjustable lightweight partition and protective support for the cross-wrap of power cables. Background Technology
[0002] An adjustable lightweight partition and protective bracket for cross-wrap of power cables is a special device designed to address problems such as entanglement, compression, and abrasion that easily occur when power cables are laid in cross or parallel configurations. Its core function is to ensure the safe operation and convenient maintenance of cables through structured partitioning, adjustable adaptation, and protective functions.
[0003] The existing utility model patent with publication number CN210957649U discloses a support for cross-fixing cables, including a support column, an outer fitting, and a crossarm. The support column has a base at its lower part, which is fixed to the ground. The support column and the outer fitting are threaded together, and the end of the outer fitting has a slot. The crossarm connects to the slot. This utility model allows for detachable installation of the outer fitting and the crossarm, and its height can be adjusted. The crossarm can fix cables in multiple directions, making comprehensive use of space and facilitating the operation and maintenance of cables within the station.
[0004] The aforementioned bracket restricts the relative position between the upper and lower bracket crossarms and the angle of the bracket crossarms through a threaded structure. During use, the cable will sway, and the sway will be transmitted to the bracket, causing the bracket to vibrate. This will cause the angle and relative position of the bracket crossarms to move, resulting in poor limiting effect. At the same time, when the cable sways up and down, the stress is concentrated on both sides of the slot, causing wear between the cable and the two ends of the slot, which will affect the service life of the cable. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable lightweight partition and protective bracket for the cross-wrap of power cables, which solves the problems of easy wear caused by cable swaying and poor limiting effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: An adjustable lightweight partition and protective bracket for the cross-wrap of power cables includes a connecting frame, and a limiting mechanism is provided above the connecting frame to restrict the position of the cable and reduce cable sway. The limiting mechanism includes: The support assembly includes a secondary stud inserted above the connecting frame, a support spring inserted on the outer side of the bottom end of the secondary stud, a protective sleeve fixedly installed on the bottom end of the secondary stud, a support frame movably installed on the outer side of the secondary stud, a synchronizing rod inserted above the support frame, and a limit ring movably installed on the top end of the secondary stud. A buffer assembly, positioned above the support assembly, is used to restrict the position of a single cable.
[0007] Preferably, the buffer assembly has multiple equidistantly installed on both sides of the support frame. The buffer assembly includes a limiting tube inserted through the top of the support frame. A rubber sleeve is fixedly installed inside the limiting tube. A movable column is inserted through the rubber sleeve. A buffer spring is inserted through the outside of the movable column. A support base is fixedly installed at the top of the movable column. A limiting block is provided above the support base. A bolt is inserted through the limiting block.
[0008] Preferably, the bottom end of the secondary stud is provided with a smooth cylindrical structure with protrusions on both sides, and the secondary stud and the connecting frame form a sliding connection. The pitch at the center of the secondary stud is greater than the pitch at the top. The support spring is located inside the protective sleeve, between the bottom end of the secondary stud and the top end of the support frame.
[0009] Preferably, the support frame is movably connected to the secondary stud via a threaded structure, the bottom end of the synchronizing rod is slidably connected to the support frame, the top end of the synchronizing rod is connected to the limiting ring via a threaded structure, and the limiting ring is connected to the secondary stud via a threaded structure at the top end of the secondary stud.
[0010] Preferably, the bottom end of the inner wall of the limiting tube is provided with an annular protrusion that fits into the movable column, the inner wall of the rubber sleeve is in contact with the outer side of the movable column, and the movable column, the rubber sleeve, and the limiting tube form a sliding connection.
[0011] Preferably, the bottom end of the movable column is provided with a disc-shaped protrusion, the buffer spring is located between the support base and the limiting tube, and the limiting block is connected to the support base by bolts.
[0012] Beneficial effects This utility model provides an adjustable lightweight protective bracket for the cross-wound joints of power cables. Compared with the prior art, it has the following advantages: (1) The adjustable lightweight partition protection bracket at the cross-wrap of the power cable first drives the support seat and the limit block to move synchronously when the cable sways, and then pushes the movable column to slide in the limit tube. At this time, the buffer spring extends and retracts between the support seat and the limit tube, which can directly absorb most of the swaying impact force and prevent the cable from colliding hard with the limit block and support seat due to violent swaying. At the same time, the rubber sleeve inside the limit tube is in close contact with the outer side of the movable column, which provides damping for the sliding of the movable column and slows down the swaying speed. On the other hand, the flexible material of the rubber sleeve can avoid the hard metal friction between the movable column and the limit tube, and indirectly reduce the vibration amplitude transmitted from the cable to the movable column. In addition, the support spring on the outside of the secondary stud will deform with the sliding of the secondary stud, further buffering the remaining vibration, reducing the overall swaying amplitude of the cable, and preventing the cable from being worn by other components due to long-term high-frequency friction, thereby extending the service life of the cable.
[0013] (2) The adjustable lightweight partition protection bracket at the cross-wrap of the power cable is connected to the connecting frame by a secondary stud. The protruding structure on both sides of its bottom end not only restricts the sliding stroke of the secondary stud (to prevent slippage), but also restricts the rotation angle of the secondary stud, so as to avoid the secondary stud from shifting due to shaking. The support frame is connected to the secondary stud by a threaded structure. With the help of the synchronous rod, the support frame and the limit ring are linked and constrained, so that the support frame cannot rotate or shift at will when vibrating (the two ends of the synchronous rod are connected to the support frame and the limit ring respectively, and the pitch at the center of the secondary stud is greater than the pitch at the top, so the two form a stable structure that restrains each other). From the perspective of cable fixing, multiple buffer components are installed equidistantly on both sides of the support frame. Each buffer component can fix a cable individually by bolting it to the support base through a limiting block, thus avoiding multiple cables from crossing and tangling. At the same time, the annular protrusion at the bottom of the inner wall of the limiting tube engages with the disc-shaped protrusion at the bottom of the movable column, which can limit the sliding range of the movable column and prevent the movable column from slipping and causing the cable to lose support. The whole system forms a reliable limiting system that is "laterally anti-entanglement, longitudinally anti-deviation, and vibration anti-displacement", which solves the problem of poor limiting effect of traditional brackets.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-4 This utility model provides a technical solution: an adjustable lightweight protective bracket for the cross-wrap of power cables includes a connecting frame 1, and a limiting mechanism 2 is provided above the connecting frame 1 to limit the position of the cable and reduce cable sway. The limiting mechanism 2 includes: The support assembly 21 includes a secondary stud 211 inserted and installed above the connecting frame 1. A support spring 212 is inserted and installed on the outer side of the bottom end of the secondary stud 211. A protective sleeve 213 is fixedly installed on the bottom end of the secondary stud 211. A support frame 214 is movably installed on the outer side of the secondary stud 211. A synchronizing rod 215 is inserted and installed above the support frame 214. A limit ring 216 is movably installed on the top end of the secondary stud 211. The bottom end of the secondary stud 211 is provided with a smooth cylindrical structure with protrusions on both sides. The secondary stud 211 and the connecting frame... A sliding connection is formed between the two parts. The pitch at the center of the secondary stud 211 is greater than the pitch at the top. The support spring 212 is located inside the protective sleeve 213, between the bottom end of the secondary stud 211 and the top end of the support frame 214. The support frame 214 is connected to the secondary stud 211 through a threaded structure. The bottom end of the synchronizing rod 215 is connected to the support frame 214 through a sliding connection. The top end of the synchronizing rod 215 is connected to the limiting ring 216 through a threaded structure. The limiting ring 216 is connected to the secondary stud 211 through the threaded structure at the top end of the secondary stud 211.
[0017] Specifically, the connecting frame 1 can restrict the movement direction of the secondary stud 211. The protruding structures on both sides of the bottom end of the secondary stud 211 can restrict the movement stroke of the secondary stud 211, prevent the secondary stud 211 from slipping, and limit the rotation angle of the secondary stud 211. When the cable shakes and causes the secondary stud 211 to move up and down, the secondary stud 211 will squeeze the support spring 212. The deformation of the support spring 212 absorbs part of the force generated by the vibration. The support frame 214 can restrict the position of the buffer component 22. The threaded connection makes it easy to adjust the orientation of the support frame 214. Since the thread pitch at the installation location of the support frame 214 is greater than the thread pitch at the installation location of the limit ring 216, after the support frame 214 and the limit ring 216 are connected by the synchronizing rod 215, the support frame 214 and the limit ring 216 are restricted by the synchronizing rod 215, forming a linkage structure. This allows the support frame 214 and the limit ring 216 to restrict each other, preventing vibration from causing the rotation angle of the support frame 214 to change.
[0018] A buffer assembly 22, positioned above the support assembly 21, is used to limit the position of a single cable. The buffer assembly 22 has multiple equidistantly installed sections on both sides of the support frame 214. The buffer assembly 22 includes a limiting tube 221 inserted into the support frame 214. A rubber sleeve 222 is fixedly installed inside the limiting tube 221. A movable column 223 is inserted into the rubber sleeve 222. A buffer spring 224 is inserted into the outer side of the movable column 223. A support base 225 is fixedly installed at the top of the movable column 223. A limit block 226 is provided at the top, and a bolt 227 is inserted and installed above the limit block 226. The bottom end of the inner wall of the limit tube 221 is provided with an annular protrusion that fits into the movable column 223. The inner wall of the rubber sleeve 222 contacts the outer side of the movable column 223. The movable column 223, the rubber sleeve 222, and the limit tube 221 form a sliding connection. The bottom end of the movable column 223 is provided with a disc-shaped protrusion. The buffer spring 224 is located between the support base 225 and the limit tube 221. The limit block 226 and the support base 225 are connected by bolts 227.
[0019] Specifically, the rubber sleeve 222 provides a certain resistance to the up-and-down movement of the movable column 223. When the cable sways, it will cause the support base 225 and the limiting block 226 to move up and down synchronously, driving the movable column 223 to move up and down. The upper and lower ends of the buffer spring 224 are fixedly connected to the support base 225 and the limiting tube 221, respectively, so that the buffer spring 224 is stretched or compressed during the up-and-down movement of the movable column 223, thereby reducing the impact of vibration on the connection between the cable and the support base 225 and the limiting tube 221. At the same time, the contents not described in detail in this specification are all prior art known to those skilled in the art.
[0020] During operation, the connecting frame 1 is first fixed in the designated installation position. Then, the position and orientation of the support frame 214 are adjusted according to the cable laying requirements. Since the support frame 214 is movably connected to the secondary stud 211 via a threaded structure, its angle can be adjusted by rotating the support frame 214. At the same time, the bottom end of the synchronizing rod 215 is slidably connected to the support frame 214, and the top end is connected to the limiting ring 216 via a threaded structure. The limiting ring 216 is connected to the secondary stud 211 via the threaded structure at the top end of the secondary stud 211. After adjustment, the limiting ring 216 is tightened, so that the support frame 214 and the limiting ring 216 form a linkage limiting structure through the synchronizing rod 215, preventing the support frame 214 from rotating arbitrarily. Next, a single cable is placed on the support base 225, and the limiting block 226 is fixed above the support base 225 with bolts 227 to achieve initial cable fixation. Multiple buffer components 22 are equidistantly installed on both sides of the support frame 214, which can fix multiple cables separately. When the cable vibrates, the vibration is first transmitted to the support base 225 and the limiting block 226, causing the movable column 223 to slide inside the limiting tube 221 and the rubber sleeve 222 (the annular protrusion at the bottom of the inner wall of the limiting tube 221 engages with the disc-shaped protrusion at the bottom of the movable column 223 to prevent the movable column 223 from slipping out of the limiting tube 221). At this time, the buffer spring 224 located between the support base 225 and the limiting tube 221 expands and contracts with the sliding of the movable column 223, while the rubber sleeve 222 and the outer side of the movable column 223... The side contact provides damping resistance, initially absorbing the impact force generated by the shaking; the remaining shaking will be transmitted to the secondary stud 211, causing the secondary stud 211 to slide on the connecting frame 1 (the smooth cylindrical structure with protrusions on both sides of the bottom end of the secondary stud 211 restricts its sliding direction and stroke to prevent slippage). At this time, the support spring 212 located inside the protective sleeve 213, between the bottom end of the secondary stud 211 and the top end of the support frame 214, is compressed and deformed, further absorbing the shaking energy, and finally achieving stable support and shaking buffering of the cable.
