Description

Technical Field

[0001] This utility model relates to the technical field of anti-galling counterweight devices, and in particular to an anti-galling counterweight device for overhead power lines. Background Technology

[0002] Overhead lines are very common in the construction of high-voltage lines. The cables of overhead lines are relatively long and the distance between two base stations is relatively large, which makes it very easy for the overhead lines to sway in windy weather. Therefore, counterweight devices are often installed on overhead lines to increase the weight of the cables and reduce the amplitude of swaying.

[0003] In practical applications, existing anti-galloping counterweight devices have relatively complete structures and functions, and can meet basic usage requirements. However, the following problems still exist:

[0004] In actual use, overhead lines usually have multiple cables, and the existing counterweights are installed separately. This means that two adjacent cables are very likely to collide due to shaking and become entangled. The counterweights are also very likely to be damaged by collisions, which is very inconvenient.

[0005] Therefore, this utility model provides an anti-galling counterweight device for overhead power lines. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an anti-galling counterweight device for overhead power lines.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an anti-galling counterweight device for overhead lines, comprising three mounting blocks and cables, wherein an adjustment buffer structure is provided between every two mounting blocks, the adjustment buffer structure comprising a wire insertion slot, the wire insertion slot being opened on one side of the mounting block, the inside of the wire insertion slot being provided with a rubber ring frame, and the cables being inserted into the inner wall of the rubber ring frame; a disassembly and assembly counterweight structure is provided at the bottom of the mounting blocks, the disassembly and assembly counterweight structure comprising a rectangular clamping frame, the top of the rectangular clamping frame being fixedly connected to the bottom of the mounting blocks.

[0008] In a preferred embodiment, fixing rods are symmetrically fixedly connected to both sides of the mounting block located in the middle position. A sliding cylinder is slidably connected to one end of each fixing rod. Two first rectangular plates are symmetrically fixedly connected to the outer surface of the sliding cylinder. Two second rectangular plates are symmetrically fixedly connected to the top and bottom of the mounting blocks located on both sides. A threaded rod is fixedly connected to one side of one of the first rectangular plates. A threaded cylinder is threaded to one end of the threaded rod. The threaded cylinder is rotatably connected to the inner wall of one of the second rectangular plates. An operating block is fixedly connected to one side of the threaded cylinder. A fixing round rod is fixedly connected to one side of the other second rectangular plate. A sliding cylinder is slidably connected to one end of the fixing round rod. One side of the sliding cylinder is fixedly connected to the other second rectangular plate.

[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded rod and the screw hole cylinder, the mounting blocks on both sides can be driven to move, thereby adjusting the distance between them and the screw hole cylinder, so that the positional distance between the mounting blocks on both sides and the mounting block in the middle position is adjustable. This can be adjusted according to the distance between the cables in the actual overhead line. Moreover, the mounting blocks are connected and cooperate with each other, so that the cables on adjacent overhead lines will not collide or entangle with each other.

[0010] In a preferred embodiment, a buffer spring is fitted on the outer surface of the fixing rod, and the two ends of the buffer spring are fixedly connected to the mounting block and the sliding cylinder, respectively.

[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the buffer spring, when the positions of the mounting blocks on both sides and the mounting block in the middle change, the sliding cylinder can be pulled to slide on the fixed rod, thereby causing the buffer spring to stretch or compress, thus providing buffering.

[0012] In a preferred embodiment, a rectangular card block is snapped into the inner wall of the rectangular card frame, and a counterweight is fixedly connected to the bottom of the rectangular card block. A first insertion hole is opened on one side of the rectangular card frame, and a second insertion hole is opened on one side of the rectangular card block. A threaded insertion rod is inserted into the inner wall of the first insertion hole and the second insertion hole, and a fixing nut is threaded to one end of the threaded insertion rod.

[0013] The technical effect of adopting the above-mentioned further solution is that: by setting rectangular card blocks and rectangular card frames, counterweights can be installed, thereby increasing the weight of the cable. Different weights of counterweights can be installed according to the actual situation, thereby improving the stability of the cable.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] By setting up an adjustable buffer structure, the distance between the mounting blocks on both sides and the mounting block in the middle can be adjusted under the action of the threaded rod and the threaded cylinder. This allows for installation adjustments based on the actual distance between the cables. Adjacent cables are connected by components such as sliding cylinders and fixed rods, preventing them from colliding or tangling during movement. Furthermore, the sliding cylinders and fixed rods, in conjunction with buffer springs, allow the buffer springs to stretch and compress when the mounting blocks on both sides are pulled or squeezed, thus providing cushioning. By setting up a disassembly and assembly counterweight structure, the counterweight blocks can be disassembled and assembled using rectangular clips and rectangular clip frames, along with threaded inserts and other components, thereby increasing the counterweight and stability of the cables.

[0024] 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.

[0025] like Figures 1-4 As shown, this embodiment provides a technical solution: an anti-galling counterweight device for overhead lines, comprising three mounting blocks 1 and cables 2. An adjusting buffer structure 3 is provided between every two mounting blocks 1. The adjusting buffer structure 3 includes a cable insertion slot 31, which is located on one side of the mounting block 1. A rubber ring frame 32 is provided inside the cable insertion slot 31, and the cables 2 are inserted into the inner wall of the rubber ring frame 32. A disassembly and assembly counterweight structure 4 is provided at the bottom of the mounting blocks 1. The disassembly and assembly counterweight structure 4 includes a rectangular clamping frame 41, the top of which is fixedly connected to the bottom of the mounting block 1. By providing the adjusting buffer structure 3, under the action of the threaded rod 37 and the screw hole cylinder 38, the mounting blocks 1 on both sides and the middle position can be adjusted. The distance between the mounting blocks 1 can be adjusted according to the actual distance between the cables 2. Adjacent cables 2 are connected by components such as sliding cylinders 34 and fixing rods 33, preventing them from colliding and tangling during movement. Under the action of sliding cylinders 34 and fixing rods 33, in conjunction with buffer springs 35, when the mounting blocks 1 on both sides are pulled and squeezed, the buffer springs 35 can be stretched and squeezed, thus providing cushioning. By setting up a disassembly and assembly counterweight structure 4, under the action of rectangular clips 42 and rectangular clip frames 41, in conjunction with components such as threaded rods 46, the counterweight block 43 can be disassembled and assembled, thereby increasing the counterweight and stability of the cables 2.

[0026] Going a step further, such as Figure 2As shown: Mounting block 1 in the middle position has symmetrically fixed rods 33 on both sides. One end of each fixed rod 33 is slidably connected to a sliding cylinder 34. Two first rectangular plates 36 are symmetrically fixed to the outer surface of the sliding cylinder 34. Two second rectangular plates 39 are symmetrically fixed to the top and bottom of the mounting blocks 1 on both sides. One side of one of the first rectangular plates 36 is fixedly connected to a threaded rod 37. One end of the threaded rod 37 is threadedly connected to a threaded cylinder 38. The threaded cylinder 38 is rotatably connected to the inner wall of one of the second rectangular plates 39. One side of the threaded cylinder 38 is fixedly connected to an operating block 310. The other second rectangular plate 39... A fixed round rod 311 is fixedly connected to one side of the plate, and a sliding cylinder 312 is slidably connected to one end of the fixed round rod 311. One side of the sliding cylinder 312 is fixedly connected to another second rectangular plate 39. Under the action of the threaded rod 37 and the screw hole cylinder 38, the mounting blocks 1 on both sides can be moved, thereby adjusting the distance between them and the screw hole cylinder 38. This makes the positional distance between the mounting blocks 1 on both sides and the mounting block 1 in the middle adjustable, so that it can be adjusted according to the distance between the cables 2 in the actual overhead line. The mounting blocks 1 are connected and cooperate with each other, so that the cables 2 on adjacent overhead lines will not collide or entangle with each other.

[0027] The above solution also has the problem that when the mounting block 1 moves, it will pull on the fixing rod 33 and the sliding cylinder 34, which may easily lead to excessive force and damage. Figure 2 As shown: In this scheme, a buffer spring 35 is sleeved on the outer surface of the fixed rod 33. The two ends of the buffer spring 35 are fixedly connected to the mounting block 1 and the sliding cylinder 34 respectively. Under the action of the buffer spring 35, when the positions of the mounting blocks 1 on both sides and the mounting block 1 in the middle change, the sliding cylinder 34 can be pulled to slide on the fixed rod 33, thereby stretching or compressing the buffer spring 35, thus providing buffering.

[0028] The above solution also has the problem that the counterweight 43 is usually welded and fixed to the mounting block 1, which makes it impossible to replace different counterweights 43 in the future. Figure 3 and Figure 4 As shown, a rectangular block 42 is snapped into the inner wall of the rectangular frame 41, and a counterweight 43 is fixedly connected to the bottom of the rectangular block 42. A first insertion hole 44 is opened on one side of the rectangular frame 41, and a second insertion hole 45 is opened on one side of the rectangular block 42. A threaded rod 46 is inserted into the inner wall of the first insertion hole 44 and the second insertion hole 45. A fixing nut 47 is threaded to one end of the threaded rod 46. By setting the rectangular block 42 and the rectangular frame 41, the counterweight 43 can be installed, thereby increasing the weight of the cable 2. Different weights of counterweights 43 can be installed according to the actual situation, thereby improving the stability of the cable 2.

[0029] Working principle:

[0030] like Figures 1-4 As shown:

[0031] In use: Insert the rubber ring frame 32 into the inner wall of the insertion slot 31 and then snap the cable 2 into the rubber ring frame 32 to fix it in place.

[0032] Rotating the screw-hole cylinder 38 allows it to move on the outer surface of the threaded rod 37, thereby adjusting the distance between the mounting block 1 and the screw-hole cylinder 38. During the movement of the screw-hole cylinder 38, the fixed round rod 311 can slide on the inner wall of the sliding cylinder 312. When subjected to force, it can drive the sliding cylinder 34 to slide on the outer surface of the fixed rod 33, which can then work with the buffer spring 35 to deform, thereby achieving a buffering effect.

[0033] When it is necessary to replace the counterweight 43, the rectangular clip 42 is engaged with the rectangular clip frame 41, and then the threaded rod 46 is inserted into the inner wall of the first insertion hole 44 and the second insertion hole 45, and then the fixing nut 47 is fixed to the threaded rod 46.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
