Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and more specifically to an overhead cable support. Background Technology

[0002] Overhead cables refer to a method of transmitting power, communication, or other types of cables by suspending them in the air and using supporting structures. Compared to buried cables, overhead cables have advantages such as simpler installation and easier maintenance. Overhead cables can be installed in various ways, such as using utility poles, steel towers, and brackets as supporting structures.

[0003] In some cases, utility poles need to be extended to adjust cable height. The reasons for this extension are twofold: first, when roads are widened or traffic facilities such as traffic lights are added, utility poles need to be extended upwards to avoid interference between the cables on the poles and vehicles or pedestrians; second, for utility poles used in the communications field, such as telephone, internet, and television signal transmission, extending the poles can improve signal transmission quality, and increasing the pole height can reduce the possibility of signal interference from ground obstacles.

[0004] Currently, the main method for extending utility poles is to replace them. This is not only time-consuming and labor-intensive, but also wastes materials and increases costs because the height of the cable cannot be adjusted at any time. Furthermore, the angle of the brackets on the utility poles used to support the cables is fixed. If it is found that the angle of the brackets needs to be adjusted after the brackets are installed, the brackets need to be disassembled and reassembled, which wastes manpower and resources. Summary of the Invention

[0005] This invention addresses the problems of time-consuming, labor-intensive, material-wasting, and cost-increasing methods for extending cable poles when adjusting cable height, as well as the inability to freely adjust the angle of the cable support on the pole. It provides an overhead cable support that can conveniently increase cable height and flexibly adjust the angle of the cable support.

[0006] To solve the above problems, the technical solution of the present invention is: An overhead cable support includes a pole, a support cylinder that is height-adjustable and installed on the top of the pole, a support member that slides along the axial direction of the support cylinder, a drive member for driving the support member to slide, and a support for carrying cables. The bearing cylinder is fixedly sleeved outside the line rod, and the side wall of the bearing cylinder is symmetrically provided with sliding holes, which provide guidance for the sliding of the bearing component; The support member is a cylindrical frame structure, which includes two sliding rods and two retaining rings. The two retaining rings are sleeved on the outside of the support cylinder at an interval. The two sliding rods are vertically arranged between the two retaining rings. The two sliding rods are respectively placed in the sliding holes and slide up and down along the sliding holes. The driving component includes two screws, a driving ring, and two limiting rings. The screws are rotatably mounted on both sides of the bearing cylinder. Each screw vertically passes through a sliding hole and is threadedly connected to a sliding rod within the hole. A gear is fixedly sleeved on the outside of each screw, driving the screw to rotate. The gear is located at the lower part of the sliding hole. The two limiting rings are fixedly sleeved at intervals on the outside of the bearing cylinder and located below the bearing component. The driving ring is rotatably mounted on the outside of the bearing cylinder between the two limiting rings. The inner wall of the driving ring is an internal gear ring that meshes with the gear, facilitating the rotation of the screws. The bracket includes a rotating cylinder and a crossbar. The rotating cylinder is rotatably mounted outside the bearing cylinder between two retaining rings. Each of the two retaining rings is provided with a limiting bolt to restrict the rotation of the rotating cylinder, which facilitates the fixing of the rotating cylinder. Horizontal crossbars are symmetrically arranged on the left and right sides of the outer wall of the rotating cylinder.

[0007] Furthermore, a plurality of limiting bolts are threaded onto the bearing cylinder below the sliding hole. These limiting bolts are evenly distributed circumferentially along the bearing cylinder, with the head of each limiting bolt passing through the bearing cylinder and abutting against the side wall of the line pole. The limiting bolts facilitate the fixing of the bearing cylinder.

[0008] Furthermore, the rod is a hollow cylindrical body with openings at both ends, and the bearing cylinder is a cylindrical body with an opening at the bottom and a closed top, with the inner diameter of the bearing cylinder being the same as the outer diameter of the rod; The lower part of the bearing cylinder is fixedly sleeved outside the upper part of the line rod. The upper part of the bearing cylinder extends upward and is higher than the line rod. The center of the closed end of the bearing cylinder is rotatably connected to a screw rod two. The length of the screw rod two is greater than the length of the bearing cylinder. The lower end of the screw rod two extends vertically into the bearing cylinder and into the line rod. The upper end of the screw rod two extends out of the bearing cylinder and is connected to a rotating plate. The rotating plate facilitates the rotation of the screw rod two. A clamping plate is horizontally arranged inside the bearing cylinder. The clamping plate slides up and down along the inner wall of the bearing cylinder. The screw rod passes through the clamping plate and is threadedly connected to the clamping plate. The clamping plate abuts against the top of the rod. The closed end of the bearing cylinder is provided with a limiting rod. The limiting rod and the second screw are arranged parallel to each other in the bearing cylinder at intervals. The length of the limiting rod is the same as that of the second screw. The lower end of the limiting rod extends downward and passes through the clamping plate. The clamping plate is provided with a through hole for the limiting rod to pass through.

[0009] Furthermore, the upper and lower ends of the screw extend out of the bearing cylinder end face and are connected to limit plates. The limit plates are rotatably arranged on the bearing cylinder end face, and the limit plates help to prevent the screw from moving axially.

[0010] Furthermore, the inner wall of the drive ring has a circumferential array of several teeth, and the gear is placed in the sliding hole. The teeth of the gear extend out of the sliding hole and mesh with the teeth to realize the transmission between the drive ring and the gear.

[0011] Furthermore, the upper and lower end faces of the rotating drum are in contact with the retaining rings respectively. Each retaining ring is provided with a plurality of limiting bolts in the circumferential direction. The limiting bolts are threadedly connected to the retaining rings, and the heads of the limiting bolts pass through the retaining rings and are tightly pressed against the end face of the rotating drum.

[0012] Furthermore, the outer wall of the drive ring is provided with multiple grips in the circumferential direction. The grips are cylindrical rods that extend radially outward along the drive ring, making it easy to operate the drive ring to rotate.

[0013] Furthermore, each of the crossbars is provided with multiple insulating porcelain bottles at intervals. A connecting rod one is provided between the lower left end of one crossbar and the lower end of the rotating drum, and a connecting rod two is provided between the lower right end of another crossbar and the lower end of the rotating drum. The connecting rod one and the connecting rod two are arranged in an inverted "V" shape. The strength of the crossbar is increased by the connecting rod one and the connecting rod two, thereby improving the support force of the crossbar for carrying the cable.

[0014] The beneficial effects of the present invention through the above technical solution are as follows: This invention allows for easy adjustment of the height of the support pole by simply rotating the drive ring. In other words, rotating the drive ring drives the carrier to slide, which in turn moves the support up or down along the carrier cylinder, thereby adjusting the height of the support on the carrier cylinder and facilitating the adjustment of the cable installation height.

[0015] This invention utilizes a rotating plate to rotate the screw, which, in conjunction with a limiting rod, facilitates the movement of the clamping plate. This allows for adjustment of the clamping plate's position within the support cylinder. The clamping plate rests against the upper end of the line pole, thus enabling easy adjustment of the support cylinder's height and facilitating convenient extension of the line pole. It also prevents the support cylinder from slipping off the line pole, improving the connection strength between the support cylinder and the line pole. The support cylinder is fitted onto the upper end of the line pole and is easily secured using the limiting bolt.

[0016] The present invention allows for convenient adjustment of the bracket angle. The bracket is rotatably mounted on the bearing cylinder, and the bracket is easily fixed by the limiting bolts. This allows for convenient adjustment of the bracket angle. Loosening each limiting bolt allows the rotating cylinder to rotate, which can adjust the angle at which the rotating cylinder drives the crossbar to support the cable. Tightening the limiting bolts fixes the angle of the rotating cylinder. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-7 As shown, an overhead cable support includes a pole 1, which is a hollow cylindrical body open at both the top and bottom. It also includes a height-adjustable support cylinder 2 mounted on the top of the pole 1, a support member that slides axially along the support cylinder 2, a drive member for driving the support member to slide, and a support for carrying cables. Figure 1 and Figure 2 As shown.

[0026] The bearing cylinder 2 is a cylindrical body that is open at the bottom and closed at the top. The inner diameter of the bearing cylinder 2 is the same as the outer diameter of the pole 1. The bearing cylinder 2 is fixedly sleeved on the outside of the pole 1; specifically, the lower part of the bearing cylinder 2 is fixedly sleeved on the upper part of the pole 1. This fixed sleeve installation method does not mean that the bearing cylinder 2 is non-rotatable; the bearing cylinder 2 can rotate, and after rotation, it is fixed by a certain means.

[0027] In this embodiment, the support cylinder is fixed by threading multiple limiting bolts 18 to the lower end of the side wall of the support cylinder 2. These limiting bolts 18 are evenly distributed around the circumference of the support cylinder 2, with the head of each bolt passing through the support cylinder 2 and abutting against the side wall of the line rod 1. Essentially, the multiple limiting bolts 18 work together to clamp the line rod 1, thus fixing the support cylinder 2 and preventing it from rotating. When the support cylinder 2 needs to rotate, simply loosen the limiting bolts 18. At this point, the multiple limiting bolts 18 no longer clamp the line rod 1, and the support cylinder 2 can rotate.

[0028] Two sliding holes 3 are symmetrically formed on the left and right sides of the side wall of the bearing cylinder 2. The sliding holes 3 penetrate the inner and outer walls of the bearing cylinder 2. The sliding holes 3 are rectangular holes formed along the height direction of the bearing cylinder 2. Therefore, the sliding holes 3 have a certain length, but their length is less than the length of the bearing cylinder 2.

[0029] The load-bearing component is a cylindrical frame structure, comprising two sliding rods 5 and two retaining rings 6. The two retaining rings 6 are spaced apart vertically on the outside of the load-bearing cylinder 2. Each retaining ring 6 is annular. Two sliding rods 5 are vertically positioned between the two retaining rings 6, connecting and fixing the two retaining rings 6 together, thus ensuring the robustness of the load-bearing component structure. Figure 3 As shown; the carrier can also slide on the carrier cylinder 2.

[0030] It should be noted that during installation, the two slide rods 5 are symmetrically arranged between the two retaining rings 6. The upper ends of the opposite sides of the two slide rods 5 are fixedly connected to the inner wall of the upper retaining ring 6, and the lower ends of the opposite sides of the two slide rods 5 are fixedly connected to the inner wall of the lower retaining ring 6. Figure 3 As shown. The purpose of this is to allow the slide rod 5 to cooperate with the slide hole 3, that is, the two slide rods 5 are respectively placed in the slide hole 3 and slide up and down along the slide hole 3. Therefore, the slide rod 5 is a rectangular rod with its side wall sliding contacting the slide hole 3. With the cooperation of the slide rod 5 and the slide hole 3, it can provide guidance for the sliding of the bearing component on the bearing cylinder 2.

[0031] Since the upper and lower ends of the sliding hole 3 do not penetrate the bearing cylinder 2, and the sliding rod 5 and the retaining ring 6 are fixedly connected, and the sliding rod 5 needs to be placed inside the sliding hole 3, in order to facilitate the installation of the bearing component and the bearing cylinder 2, the top of the bearing cylinder 2 needs to be set as a detachable structure, that is, the closed end of the bearing cylinder 2 is detachable. Therefore, the bearing cylinder 2 includes a cylinder body 201 and a cylinder cover 202. The cylinder cover 202 is a circular cover, and the cylinder cover 202 is connected to the cylinder body 201 through a flange connection. The cylinder cover 202 is equivalent to the closed end of the bearing cylinder 2, thereby facilitating the sliding of the bearing component up and down along the sliding hole 3, such as... Figure 7 As shown.

[0032] To enable the sliding of the load-bearing component, the driving component includes two screws 7, a driving ring 8, and two limiting rings 9. Screws 7 are rotatably arranged on both sides of the load-bearing cylinder 2, and each screw 7 vertically penetrates the sliding hole 3, that is, the screws 7 are rotatably arranged in the sliding hole 3.

[0033] To limit the movement of screw 7, which means restricting its axial movement, the upper and lower ends of screw 7 extend out of the end face of bearing cylinder 2 and are connected to limit plates 25. The limit plates 25 are rotatably arranged on the end face of bearing cylinder 2. With the limit plates 25 at the end of screw 7, screw 7 can only rotate and cannot move axially.

[0034] Since the screw 7 passes through the sliding hole 3, and the slide rod 5 is also placed inside the sliding hole 3, the screw 7 and the slide rod 5 inside the sliding hole 3 are threadedly connected. Specifically, each slide rod 5 has a threaded hole 26 that passes through both ends of the slide rod 5. The screw 7 passes through the threaded hole 26 and is threadedly connected to the slide rod 5. Thus, when the screw 7 rotates, under the action of the threaded connection, the screw 7 can drive the entire bearing component to move relative to the bearing cylinder 2.

[0035] Each screw 7 is externally fixed with a gear 10, such as Figure 4 As shown, gear 10 is located at the lower part of sliding hole 3. During installation, gear 10 is first fitted onto screw 7. After gear 10 moves to the corresponding position, it needs to be fixed. This fixing is achieved using set screw 12, which is inserted radially through the tooth root between two teeth. Set screw 12 can be radially inserted between gear 10 and screw 7. The length of set screw 12 is less than the tooth root circle diameter of gear 10, effectively concealing the set screw 12 and not affecting the meshing of gear 10 with other parts. Figure 6 As shown.

[0036] Two limiting rings 9 are fixedly sleeved on the outside of the bearing cylinder 2 at intervals and located below the bearing component. The limiting rings 9 are circular rings. A driving ring 8 is rotatably installed on the outside of the bearing cylinder 2 between the two limiting rings 9. The driving ring 8 is also a circular ring and can rotate relative to the bearing cylinder 2.

[0037] To facilitate the rotation of the drive ring 8, multiple levers 27 are provided circumferentially on the outer wall of the drive ring 8. Each lever 27 is a cylindrical rod that extends radially outward along the drive ring 8. These levers facilitate the manipulation of the drive ring 8 to rotate it. Figure 5 As shown.

[0038] The rotation of the drive ring 8 drives the screw 7 to rotate; that is, the inner wall of the drive ring 8 is an internal gear ring that meshes with the gear 10. Specifically, the inner wall of the drive ring 8 has a circumferential array of teeth 13, thus forming an internal gear ring structure. The gear 10 is placed in the sliding hole 3, and the teeth of the gear 10 extend out of the sliding hole 3 and mesh with the teeth 13, such as... Figure 6As shown. The drive ring 8 rotates, and under the meshing action of the gear 10 and the teeth 13, it can drive the screw 7 to rotate, thereby moving the carrier component.

[0039] The support includes a rotating cylinder 14 and a crossbar 15. The rotating cylinder 14 is a cylindrical body with open top and bottom ends. The rotating cylinder 14 is rotatably disposed outside the bearing cylinder 2 between two retaining rings 6. The inner wall of the rotating cylinder 14 slides in contact with the outer wall of the bearing cylinder 2. The upper and lower end faces of the rotating cylinder 14 are in contact with the retaining rings 6 respectively. The upper and lower ends of the rotating cylinder 14 slide in contact with the opposite faces of the two retaining rings 6 respectively.

[0040] Both retaining rings 6 are provided with limiting bolts 16 for restricting the rotation of the rotating drum 14. Specifically, each retaining ring 6 is provided with multiple limiting bolts 16 in the circumferential direction. The limiting bolts 16 are threadedly connected to the retaining ring 6. The head of the limiting bolt 16 passes through the retaining ring 6 and abuts against the end face of the rotating drum 14. Thus, under the clamping action of the limiting bolts 16 on the two retaining rings 6, the rotating drum 14 can be fixed.

[0041] Two rectangular horizontal bars 15 are symmetrically arranged on the outer wall of the rotating drum 14. Each horizontal bar 15 has multiple insulating porcelain insulators 28 spaced apart. Since the horizontal bars 15 need to support cables, to improve their load-bearing capacity, a connecting rod 29 is installed between the lower left end of one horizontal bar 15 and the lower end of the rotating drum 14, and a connecting rod 30 is installed between the lower right end of the other horizontal bar 15 and the lower end of the rotating drum 14. Both connecting rods 29 and 30 are rectangular bars, arranged in an inverted "V" shape. Under the action of these connecting rods, the horizontal bars 15 are supported, and the entire support structure is essentially a triangular frame, thus improving its strength.

[0042] To adjust the height of the bearing cylinder 2, the upper part of the bearing cylinder 2 extends upwards above the pole 1, meaning the upper end of the bearing cylinder 2 is higher than the pole 1. For example... Figure 2 and Figure 7 As shown, a screw 19 is rotatably connected to the center of the closed end of the bearing cylinder 2. Specifically, a circular hole is provided at the center of the top surface of the bearing cylinder 2, and the screw 19 is rotatably connected to the circular hole via a bearing 20. The length of the screw 19 is greater than the length of the bearing cylinder 2. The lower end of the screw 19 extends vertically into the bearing cylinder 2 and also into the wire rod 1. The lower end of the screw 19 is lower than the lower end of the bearing cylinder 2. The upper end of the screw 19 extends out of the bearing cylinder 2 and is connected to a rotating plate 21. By operating the rotating plate 21, the screw 19 can be rotated.

[0043] A clamping plate 22 is horizontally arranged inside the bearing cylinder 2. The clamping plate 22 is a circular plate that slides up and down along the inner wall of the bearing cylinder 2. The outer wall of the clamping plate 22 is in sliding contact with the inner wall of the bearing cylinder 2. The screw 19 passes through the clamping plate 22 and is threadedly connected to the clamping plate 22. The clamping plate 22 abuts against the top of the rod 1.

[0044] The closed end of the bearing cylinder 2 is also equipped with a limiting rod 23. The limiting rod 23 is a circular rod, and it and the screw 19 are arranged parallel to each other at intervals inside the bearing cylinder 2. The length of the limiting rod 23 is the same as that of the screw 19, and the lower ends of both the screw 19 and the limiting rod 23 are located inside the rod 1. The lower end of the limiting rod 23 extends downward through the clamping plate 22, which has a through hole 24 for the limiting rod 23 to pass through. Thus, when the screw 19 rotates, the clamping plate 22 does not rotate under the restriction of the limiting rod 23, but moves up and down, thereby changing the installation height of the bearing cylinder 2.

[0045] When it is necessary to extend the length of the line rod 1, the present invention can achieve the purpose of changing the length of the line rod 1 by adjusting the position of the clamping plate 22 in the bearing cylinder 2 according to the length that the line rod 1 needs to be extended.

[0046] The adjustment method for the position of the clamping plate 22 is as follows: Rotate the rotating plate 21, causing the rotating plate 21 to drive the screw 19 to rotate. When the screw 19 rotates, the rotation of the clamping plate 22 is restricted by the limiting rod 23. When the screw 19 rotates, it can only drive the clamping plate 22 to move upward or downward, thereby changing the height of the bearing cylinder 2. The distance from the bottom surface of the clamping plate 22 to the top of the bearing cylinder 2 is the length that the line rod 1 needs to be extended. After adjusting the height of the bearing cylinder 2, tighten each limiting bolt 18 at the bottom of the bearing cylinder 2, so that the head of each limiting bolt 18 presses against the line rod 1, thereby fixing the bearing cylinder 2 and fixing the bearing cylinder 2 and the line rod 1 together, thus realizing the adjustment of the length of the line rod 1.

[0047] When adjusting the height of the bracket on the bearing cylinder 2, grip either lever 27 and rotate the drive ring 8 clockwise. As the drive ring 8 rotates, the two screws 7 rotate in the same direction and synchronously under the meshing transmission of the teeth 13 and gear 10. When the two screws 7 rotate, each screw 7 is threadedly connected to a sliding rod 5, which is guided by the sliding hole 3, causing the two sliding rods 5 to move upwards. This drives the two connected retaining rings 6 to move upwards, thereby moving the entire bearing component upwards. When the two retaining rings 6 move upwards, they drive the rotating cylinder 14 between them to move upwards, which also drives the bracket on the bearing component to move upwards along the height direction of the bearing cylinder 2, thus adjusting the upward height of the bracket. Conversely, rotating the drive ring 8 counterclockwise drives the bracket downwards.

[0048] In this invention, after the rotating drive ring 8 adjusts the bracket to the required height, when it is necessary to adjust the angle of the bracket for cable mounting, each limit bolt 16 is loosened, and the rotating cylinder 14 can be rotated, so that the rotating cylinder 14, along with the two crossbars 15, rotates circumferentially along the outer wall of the bearing cylinder 2. When the rotating cylinder 14 is adjusted to the appropriate angle, each limit bolt 16 is tightened, so that the head of each limit bolt 16 presses against the rotating cylinder 14, and the rotating cylinder 14 is fixed.

[0049] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Any equivalent or similar modifications or substitutions to the technical solutions of the invention without departing from the spirit of the invention or the scope of disclosure shall fall within the protection scope of the present invention.
