Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to a spacer for overhead lines. Background Technique

[0002] A spacer refers to a fitting installed on bundled conductors to fix the spacing between each bundled conductor to prevent the conductors from whipping each other, suppressing aeolian vibration and sub-span oscillation. According to the erection of the line, it can be divided into spacers for two-conductor, four-conductor, six-conductor, and eight-conductor bundles. Existing spacers mostly adopt splicing and use bolts to lock and stop for overhead lines;

[0003] The utility model with the publication number CN109904822A discloses a spacer. Its fixing clamp is connected to the base through a double-headed bolt, and can be telescoped according to the distance between different conductors when used in cooperation with an adjusting nut, which is convenient for installation. A washer is installed inside the fastening clamp, which can effectively reduce the damping of the conductor and reduce the wear of the conductor;

[0004] However, the above-mentioned spacer for overhead lines still has the following problems in actual use: Although a length-adjustable spacer clamp is used to lock and position the line, when installing, the clamp needs to be opened to clamp the line. While bearing the weight of the whole spacer, bolts also need to be inserted for locking. There is no anti-detachment mechanism in the whole clamping process, which cannot ensure the safety when inserting bolts for locking. At the same time, the whole spacer has a large volume, and the clamping mechanism protruding from the bracket is prone to bumping when the staff carry it onto the line tower, affecting the stability of the subsequent spacer installation.

[0005] Therefore, we propose a spacer for overhead lines to solve the problems mentioned above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a spacer for overhead lines to solve the problems that a length-adjustable spacer clamp is used to lock and position the line, but when installing, the clamp needs to be opened to clamp the line. While bearing the weight of the whole spacer, bolts also need to be inserted for locking. There is no anti-detachment mechanism in the whole clamping process, which cannot ensure the safety when inserting bolts for locking. At the same time, the whole spacer has a large volume, and the clamping mechanism protruding from the bracket is prone to bumping when the staff carry it onto the line tower, affecting the stability of the subsequent spacer installation.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A spacer for overhead lines, including a spacer bracket body, and weight-reducing slot holes equally angled and opened inside the spacer bracket body;

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 - 6 , the present utility model provides the following technical solutions:

[0031] Embodiment 1: In order to solve the problems existing in the actual use of the existing spacer, therefore, in this embodiment, through the following technical solutions, a spacer for overhead lines includes a spacer bracket body 1 and weight reduction slots 2 equally angled in the spacer bracket body 1; wherein, bearing lining plates 6 are fixedly arranged on both the front and rear sides inside the spacer bracket body 1, monitoring hosts 7 are fixedly arranged at the center positions on the outer sides of the bearing lining plates 6 on both the front and rear sides, and communication modules 8 are fixedly arranged above the outer sides of the bearing lining plates 6 on both the front and rear sides;

[0032] The outer ends of the spacer bracket body 1 are provided with positioning mechanisms at equal angles. The positioning mechanism includes a flipping carrier 3, and the inner ends of the flipping carrier 3 are hinged to the outer ends of the spacer bracket body 1 at equal angles; the positioning mechanism includes a positioning pin 9, and the positioning pins 9 are fixedly arranged inside the spacer bracket body 1 at equal angles. An insertion positioning plate 10 is elastically arranged inside the positioning pins 9 arranged at equal angles. Moreover, the positioning mechanism includes a positioning locking groove 11, and the positioning locking groove 11 is opened in the middle and below the inner end of the flipping carrier 3;

[0033] The flipping carrier 3 is snap-connected to the outer end of the insertion positioning plate 10 through the positioning locking groove 11 opened below the inner end. At this time, both the flipping carrier 3 and the clamping mechanism at the outer end are received inside the spacer bracket body 1. When the positioning locking groove 11 in the middle of the inner end of the flipping carrier 3 is snap-connected to the outer end of the insertion positioning plate 10, it drives the clamping mechanism at the outer end to be in an extended state for positioning the line;

[0034] Such as Figures 1 - 2 、 Figures 4 - 5 As shown, the spacer bracket body 1 is installed with the monitoring host 7 and the communication module 8 through the bearing liners 6 on the front and rear sides inside, so as to monitor the operating conditions of the overhead line and the surrounding environment in real time after installation. At the same time, in the initial state, both the positioning mechanism and the clamping mechanism are received inside the spacer bracket body 1, so as to improve the convenience for the staff during the handling of the spacer bracket body 1 and the transportation on the power tower, and avoid the positioning mechanism and the clamping mechanism protruding outside the spacer bracket body 1 from being collided;

[0035] Furthermore, by manually sliding the insertion positioning plate 10 of the positioning pins 9 arranged at equal angles inside the spacer bracket body 1 inward, the outer end of the elastically connected insertion positioning plate 10 no longer engages with the positioning locking groove 11 below the inner end of the flipping carrier 3. Then, the flipping carrier 3 in the unlocked state drives the clamping mechanism to flip outward. At the same time, when the positioning locking groove 11 in the middle of the inner end of the flipping carrier 3 corresponds to the outer end of the insertion positioning plate 10, it extends outward due to the elastic action and then inserts into the positioning locking groove 11, so as to lock and limit the flipping carrier 3 and the clamping mechanism at its outer end, and thus facilitate the subsequent installation and connection with the overhead line.

[0036] Embodiment 2: To solve the problems existing in the actual use of the existing spacer dampers, the following technical solutions are adopted in this embodiment. The outer ends of the equally-angled flipping carrier frames 3 are each provided with a clamping mechanism. The clamping mechanism includes a main clamping arc plate 4, and the outer end of the main clamping arc plate 4 is hinged to the outer end of the secondary clamping arc plate 5. The positioning mechanism includes a guiding sleeve 12, and the guiding sleeve 12 is rotatably arranged above the flipping carrier frame 3 through a bearing. The inner part of the guiding sleeve 12 is threadedly connected to the outer end of a guiding threaded rod 13, and the guiding threaded rod 13 is fixedly installed on the top surface of the main clamping arc plate 4 included in the clamping mechanism. By rotating the guiding threaded rod 13, the threadedly connected guiding threaded rod 13 and the main clamping arc plate 4 are driven to move in the inner and outer directions.

[0037] The clamping mechanism includes positioning sliders 14, and the positioning sliders 14 are fixedly installed on the front and rear sides of the inner end of the main clamping arc plate 4. The main clamping arc plate 4 is slidably arranged inside the flipping carrier frame 3 included in the positioning mechanism through the positioning sliders 14 on the front and rear sides of its inner end. Moreover, the maximum sliding length of the main clamping arc plate 4 is less than the length of the guiding threaded rod 13 above it. The clamping mechanism includes bolt mounting holes 15, and the bolt mounting holes 15 are respectively opened in the middle parts of the main clamping arc plate 4 and the secondary clamping arc plate 5. The main clamping arc plate 4 and the secondary clamping arc plate 5 are arranged in a one-to-one correspondence. The inner parts of the outer ends of the hinged main clamping arc plate 4 and the secondary clamping arc plate 5 are in a round hole shape to clamp and lock the overhead line.

[0038] The clamping mechanism includes plugging positioning columns 16, and the plugging positioning columns 16 are fixedly installed above the inner end of the secondary clamping arc plate 5. The front and rear sides of the upper end of the plugging positioning column 16 are elastically connected to the inner ends of anti-detachment inclined blocks 17. An insertion locking groove 18 is opened inside the main clamping arc plate 4 included in the clamping mechanism. At the same time, the insertion locking groove 18 is used for the plugging positioning column 16 and the anti-detachment inclined blocks 17 to penetrate and lock.

[0039] As Figures 4 - 6 shown, when it is necessary to lock and position the line through the clamping mechanism, first remove the bolts installed through the bolt mounting holes 15 in the middle of the main clamping arc plate 4 and the secondary clamping arc plate 5. Then, manually press the anti-detachment inclined blocks 17 at the front and rear ends of the plugging positioning column 16 inward, so that the plugging positioning column 16 can be unlocked through the insertion locking groove 18. Then, manually flip the secondary clamping arc plate 5 hinged to the outer end of the main clamping arc plate 4 outward to be able to position and lock the line.

[0040] Further, install the circuit between the main clamping arc plate 4 and the auxiliary clamping arc plate 5, and then reverse the auxiliary clamping arc plate 5 again, so that the plug-in positioning column 16 above the inner end drives through the plug-in locking groove 18 opened inside the main clamping arc plate 4, and after passing through, the anti-drop inclined block 17 connected elastically extends outwards, so that the main clamping arc plate 4 and the auxiliary clamping arc plate 5 can clamp the circuit without installing bolts, and there is no need for operators to manually support to prevent falling off, improving the stability and convenience of the installation of the clamping mechanism;

[0041] Meanwhile, when installing the interval bracket body 1 according to circuits of different specifications, rotate the guide sleeve 12 arranged above the flipping carrier 3 manually. The guide screw rod 13 threadedly connected to the guide sleeve 12 is fixedly installed above the main clamping arc plate 4. At the same time, the main clamping arc plate 4 slides through the inside of the flipping carrier 3 through the positioning sliders 14 on the front and rear sides, so as to drive the guide screw rod 13, the main clamping arc plate 4 and the auxiliary clamping arc plate 5 to move in the inner and outer sides through the rotation of the guide sleeve 12, so as to adapt to circuits with different specification intervals and improve the stability of the overhead line.

[0042] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacement on some of the technical features.
