Description

Technical Field

[0001] The present invention relates to the technical field of cable positioning, and particularly relates to a cable positioning device and a positioning method for the construction of a distribution power grid. Background Art

[0002] When constructing a distribution power grid, according to the design requirements, the electric power of the power plant needs to be laid through cables in the designated power consumption area. When laying the cables over a long distance, in order to avoid situations such as the cables being pulled out of position or intertwined, it is often necessary to use a special positioning device to tightly fix the laid cables.

[0003] For this reason, the patent specification with the publication number CN117833110A discloses a cable positioning device for the construction of a distribution power grid, including a support part. One side of the support part is fixedly connected with a detection component, the top of the detection component is fixedly connected with a cleaning component, one side of the top of the detection component is fixedly connected with a lifting part, the inside of the detection component is fixedly connected with a guiding component, and a protection component is arranged on one side of the guiding component. The detection component includes a detection base, detection cameras are arranged on both sides of the front of the detection base, a servo motor is arranged at the bottom of the detection base, and a control module is arranged inside the detection base. By setting the protection component and the cleaning component, on the one hand, the protection component can scrape the surface of the cable to remove the obstacles on its surface. On the other hand, the cleaning component can clean the protection component, realizing automatic and continuous cleaning of the cable surface and protecting the safety of the cable during the laying process. The above cable positioning device has a good positioning and fastening effect when in use, but there are still some problems:

[0004] When the above cable positioning device is in use, since the cables are mostly laid at high positions such as utility poles and transmission towers, the cumbersome operation of relatively heavy or large-sized positioning devices is not convenient for high-altitude operations. Summary of the Invention

[0005] The purpose of the present invention is to provide a cable positioning device and a positioning method for the construction of a distribution power grid, so as to solve the defect that the existing cable positioning device for the construction of a distribution power grid has cumbersome operation and is not convenient for high-altitude operations.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A cable positioning device for the construction of a distribution power grid, including a mounting frame and a top cover. One side of the top of the mounting frame is provided with a base, and one side of the mounting frame is fixedly connected with an auxiliary structure. The top cover is rotatably connected to the top of the base. One side of both ends of the base and the top cover is fixedly connected with a guiding slide bar. A fastening and positioning structure is arranged on the top of the top cover. The fastening and positioning structure includes a first sliding frame, a threaded sleeve, a fastening screw, a second sliding frame, an arc-shaped pressing plate, a hinge rod, a connecting rod, a lower hanging buckle, a threaded seat, an upper hanging buckle, an adjusting screw, a guiding groove and a scissors frame. The first sliding frame is arranged on one side of the top cover.

[0007] During use, the mounting frame is pre-installed at a specified position on a utility pole or a transmission tower. The cable passes through the inside of the device by flipping the top cover and the first sliding frame. Subsequently, the fastening screw is tightened so that a plurality of arc-shaped pressing plates press and fasten the outer side of the cable.

[0008] Preferably, the guiding slide bars are symmetrically distributed about the vertical center line of the top cover.

[0009] Preferably, the auxiliary structure includes a support arm, a flipping frame, a high-pressure spring, a limiting frame and a roller. The support arm is fixedly connected to one side of the mounting frame. One side of the support arm is rotatably connected with a flipping frame. A fastening screw is installed on one side of the flipping frame. The top of the flipping frame is fixedly connected with a limiting frame. A roller is rotatably connected to the lower part inside the limiting frame.

[0010] Preferably, the support arms are equidistantly distributed on one side of the mounting frame, and the support arm and the flipping frame are in a flipping structure, so as to buffer the shaking of the cable.

[0011] Preferably, the top of the first sliding frame is fixedly connected with a threaded sleeve. The fastening screw is threadedly connected to the inside of the threaded sleeve. The bottom of the first sliding frame is rotatably connected with a second sliding frame. An arc-shaped pressing plate is arranged below the fastening screw. Hinge rods are hinged on both sides of the arc-shaped pressing plate. One side of the hinge rod is hinged with a connecting rod. A lower hanging buckle is installed on the outer side of the guiding slide bar. The top of one end of the lower hanging buckle is fixedly connected with a threaded seat. An upper hanging buckle is arranged above the lower hanging buckle. One end of the upper hanging buckle is rotatably connected with an adjusting screw. Guiding grooves are opened inside the other ends of the lower hanging buckle and the upper hanging buckle. A scissors frame is arranged at one end of the guiding groove.

[0012] Preferably, the first sliding frame and the guiding slide bar are in a sliding structure, and the fastening screw and the top cover are in a rotating structure.

[0013] Preferably, the second sliding frame and the guiding slide bar are in a sliding structure, and the threaded seat and the adjusting screw are in a threaded connection structure.

[0014] Preferably, the cross-sectional area of the inner diameter of the arc-shaped pressing plate is smaller than the cross-sectional area of the inner diameters of the top cover and the first sliding frame, so that the cable can be laid.

[0015] Preferably, the guiding groove and the scissor frame are in a sliding structure, and the lower hanging buckle and the guiding sliding rod are in a clamping structure, so that the two groups of guiding sliding rods on the same side can be pulled and tightened. The center lines of the hinge rods and the top cover are in the same vertical plane, so that the arc-shaped pressing plate can symmetrically press and fasten the cable.

[0016] A cable positioning method for the construction of a distribution power grid includes the following steps:

[0017] S1. Installation: Use fasteners such as bolts to install the mounting frame at a specified position such as a utility pole or a transmission tower.

[0018] S2. Cable laying: When laying the cable, place it on the top of the base, and then flip the top cover to cover the cable.

[0019] S3. Tightening and positioning: Rotate the tightening screw to drive the threaded sleeve to drive the first sliding frame to slide along the guiding sliding rod towards the top cover. Under the hinge of the hinge rods, the upper and lower groups of arc-shaped pressing plates are pushed to press and fasten the outside of the electric connection.

[0020] S4. Locking: Use fasteners such as bolts to tighten the base, the top cover, the first sliding frame and the second sliding frame. Then, the lower hanging buckle and the upper hanging buckle are clamped on the two groups of guiding sliding rods on the same side. Then, tighten the adjusting screw to pull the lower hanging buckle and the upper hanging buckle closer to the two groups of guiding sliding rods on the same side.

[0021] S5. Cable adjustment: Pass the cable passing through the inside of the tightening and positioning structure through the inside of the limiting frame and the top of the roller.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows: By rotating the tightening screw, several arc-shaped pressing plates press the cable at multiple points for fastening, without the need to use many other parts. At the same time, the cable passes through the inside of the limiting frame and the rollers. When the cable shakes under the influence of wind force, the flip frame pulled by the elastic force of the high-pressure spring will buffer the pull.

[0023] 1. Rotate the tightening screw to make the first sliding frame and the second sliding frame slide towards the top cover. As they slide, several hinge rods and connecting rods are stressed and hinged and folded, and thus several arc-shaped pressing plates press and fasten the outside of the cable.

[0024] Furthermore, the lower hanging buckle and the upper hanging buckle are installed on the outer sides of the two groups of guiding sliding rods on the same side for clamping. Then, manually tighten the adjusting screw to pull the lower hanging buckle closer to the upper hanging buckle, so as to keep the two groups of guiding sliding rods on the same side stable.

[0025] 2. When the cable sways under the blowing of strong wind, at this time, under the elastic pull of the high-pressure spring, the flipping frame can be flipped to a certain extent, and the swaying of the cable is buffered thereby, thus avoiding excessive swaying amplitude of the cable and causing damage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-8, a cable positioning device for distribution power grid construction provided by the present invention includes a mounting frame 1 and a top cover 3. One side of the top of the mounting frame 1 is provided with a base 2, and the top cover 3 is rotatably connected to the top of the base 2. One side of each of the two ends of the base 2 and the top cover 3 is fixedly connected with a guiding slide bar 5, and the guiding slide bars 5 are symmetrically distributed about the vertical center line of the top cover 3. One side of the mounting frame 1 is fixedly connected with an auxiliary structure 4. The auxiliary structure 4 includes a support arm 401, a turning frame 402, a high-pressure spring 403, a limiting frame 404 and a roller 405. The support arm 401 is fixedly connected to one side of the mounting frame 1. One side of the support arm 401 is rotatably connected with a turning frame 402. One side of the turning frame 402 is provided with a fastening screw 603. The top of the turning frame 402 is fixedly connected with a limiting frame 404. A roller 405 is rotatably connected to the lower part inside the limiting frame 404. The support arms 401 are equidistantly distributed on one side of the mounting frame 1, and the support arm 401 and the turning frame 402 are in a turning structure.

[0037] Refer to the attached Figure 1 and Figure 8 , since most cables are laid at a relatively high position outside, when there is a strong wind, the cables will swing under the influence of the wind force. If the cable positioning points are too tight and the swing amplitude is large, the cable positioning part is likely to be pulled and deformed or even damaged. Therefore, the support arm 401 is fixedly supported on one side of the base 2, and the cable passes through the gap between the limiting frame 404 and the roller 405, and is partially lifted under the support of the turning frame 402. When the cable swings under the blowing of the strong wind, at this time, under the elastic pulling of the high-pressure spring 403, the turning frame 402 can be turned to a certain extent, and the cable swing is buffered thereby, so as to avoid damage caused by too large a swing amplitude of the cable.

[0038] The top end of the top cover 3 is provided with a fastening and positioning structure 6. The fastening and positioning structure 6 includes a first sliding frame 601, a threaded sleeve 602, a fastening screw rod 603, a second sliding frame 604, an arc-shaped pressing plate 605, a hinge rod 606, a connecting rod 607, a lower hanging buckle 608, a threaded seat 609, an upper hanging buckle 610, an adjusting screw rod 611, a guide groove 612 and a scissors frame 613. The first sliding frame 601 is arranged on one side of the top cover 3. The top end of the first sliding frame 601 is fixedly connected with the threaded sleeve 602. The threaded sleeve 602 is internally threaded with the fastening screw rod 603. The bottom end of the first sliding frame 601 is reversibly connected with the second sliding frame 604. The arc-shaped pressing plate 605 is arranged below the fastening screw rod 603. Both sides of the arc-shaped pressing plate 605 are hinged with the hinge rod 606. One side of the hinge rod 606 is hinged with the connecting rod 607. The lower hanging buckle 608 is installed on the outer side of the guide slide bar 5. The top of one end of the lower hanging buckle 608 is fixedly connected with the threaded seat 609. The upper hanging buckle 610 is arranged above the lower hanging buckle 608. One end of the upper hanging buckle 610 is rotatably connected with the adjusting screw rod 611. Guide grooves 612 are respectively opened inside the other ends of the lower hanging buckle 608 and the upper hanging buckle 610. The scissors frame 613 is arranged at one end of the guide groove 612. The first sliding frame 601 and the guide slide bar 5 are in a sliding structure. The fastening screw rod 603 and the top cover 3 are in a rotating structure. The second sliding frame 604 and the guide slide bar 5 are in a sliding structure. The threaded seat 609 and the adjusting screw rod 611 are in a threaded connection structure. The cross-sectional area of the inner diameter of the arc-shaped pressing plate 605 is smaller than the cross-sectional area of the inner diameters of the top cover 3 and the first sliding frame 601. The guide groove 612 and the scissors frame 613 are in a sliding structure. The lower hanging buckle 608 and the guide slide bar 5 are in a clamping structure. The hinge rod 606 and the center line of the top cover 3 are in the same vertical plane.

[0039] Refer to the attached Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7, when tightly fixing and positioning the cable, lay the laid cable on the top of the base 2, then flip the top cover 3 and the first sliding frame 601 to cover it above the cable, and then rotate the fastening screw 603 to drive the threaded sleeve 602 threadedly connected thereto to drive the first sliding frame 601 and the second sliding frame 604 to slide along the outer side of the guiding slide bar 5 towards the direction of the top cover 3. As the first sliding frame 601 and the second sliding frame 604 slide, a number of hinge rods 606 and connecting rods 607 are stressed and hinged and folded in half, and thereby a number of arc-shaped pressing plates 605 press and fasten the outer side of the cable. After the cable is tightly fixed and positioned, when using traditional fasteners such as bolts to tighten the base 2, the top cover 3, the first sliding frame 601, and the second sliding frame 604, since they are exposed to the outside for a long time, the installation of a single fastener such as a bolt is likely to become loose. At the same time, it is inconvenient to carry multiple sets of fasteners such as bolts and components such as wrenches during high-altitude operations. For this reason, a lower hanging buckle 608 and an upper hanging buckle 610 are installed on the outer sides of two sets of guiding slide bars 5 on the same side for clamping, and then manually tighten the adjusting screw 611 to pull the lower hanging buckle 608 closer to the upper hanging buckle 610, thereby making the two sets of guiding slide bars 5 on the same side stable, and making the closing of the base 2 and the top cover 3 more stable and not easy to loosen during multiple installations.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
