Description

Technical Field

[0001] This utility model relates to the technical field of power tower cable fixing devices, specifically a power tower cable fixing device that is easy to adjust. Background Technology

[0002] A power tower cable fixing device is a piece of equipment used to fix and support power cables. It is typically installed on power towers, and its main function is to ensure the stable fixation of the cables on the tower, preventing them from loosening or falling due to wind or other external forces, thereby ensuring the stability and safety of power transmission. For example:

[0003] The announcement number CN220527643U discloses a maintenance-friendly cable fixing device for power transmission towers. It includes a base plate, an adjusting rod, clamping plates, and a cover plate. The adjusting rod is non-removably connected to the lower inner side of the base plate. Clamping plates, which fit snugly against the base plate, are threaded to the outer sides of both ends of the adjusting rod. Baffles are provided on the upper outer side of the adjusting rod and the upper side of the worm gear, respectively. These baffles are fixedly connected to the base plate and the cover plate. This facilitates the installation and fixing of the device onto the power transmission tower and allows for the shielding and rust prevention of some parts. The device also includes a cover plate, a movable rod, a spring, and a pressure plate. The cover plate is rotatably connected to the inner side of the upper left end of the base plate. The inner side of the cover plate is fitted with movable rods that pass through the lower fixed pressure plate at equal intervals. The outer side of the movable rods is nested with springs that fit and connect with the cover plate and the pressure plate. A first anti-slip pad is pasted and fixed inside the pressure plate, and a second anti-slip pad that is pasted and fixed to the bottom plate is correspondingly set below the first anti-slip pad. A label that is pasted and fixed to the cover plate is correspondingly set on the rear side of the movable rod. Therefore, it is convenient to quickly clamp, fix and disassemble different cables for maintenance. The cover plate, the limiting rod and the fan blade are provided. Since the upper outer side of the cover plate is fitted with an inclined limiting rod that is not detachably connected, and the upper outer side of the limiting rod is symmetrically fixed with the fan blade, it is convenient to rotate in the wind to drive away birds.

[0004] The existing technical solutions have the following drawbacks:

[0005] 1. Although existing power tower cable fixing devices can drive away birds by rotating in the wind, they are not convenient for increasing the stability of clamping and limiting when limiting the cable.

[0006] 2. At the same time, when reinforcing overhead cables, it is not convenient to install and disassemble them quickly and easily, and the operation is cumbersome. Therefore, this utility model provides an easily adjustable power tower cable fixing device to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide an easily adjustable cable fixing device for power towers. Existing cable reinforcement devices have problems such as not being able to increase the stability of clamping and limiting when limiting the cable, and not being able to install and disassemble more conveniently and quickly when reinforcing aerial cables, resulting in cumbersome operation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an easily adjustable power tower cable fixing device, comprising: a first mounting plate, and a connecting assembly disposed inside the first mounting plate, wherein a second mounting plate is disposed below the connecting assembly, and further comprising:

[0009] The connecting component includes a first reinforcing plate and a second reinforcing plate, and both the first mounting plate and the second mounting plate are connected to the connecting component by reinforcing bolts. The first reinforcing plate and the second reinforcing plate are arranged in an arch bridge configuration, and both the first reinforcing plate and the second reinforcing plate have a first clamping plate on their inner sides.

[0010] Four sets of second clamping plates are provided at equal angles on the inner side of the first clamping plate, and the upper and lower corresponding second clamping plates are connected to the limiting component. The outer end of the second clamping plate is connected to the threaded limiting rod through a bearing.

[0011] As a preferred embodiment of this utility model, the inner ends of the first mounting plate and the second mounting plate are respectively bonded and connected to the outer surfaces of the first reinforcing plate and the second reinforcing plate.

[0012] As a preferred embodiment of this utility model, the reinforcing bolt includes a connecting screw that passes through the inside of the connecting assembly, and the outer surface of the connecting screw is threaded with a connecting nut.

[0013] As a preferred embodiment of this utility model, two sets of connecting screws and connecting nuts are provided correspondingly on the top and bottom.

[0014] As a preferred embodiment of this utility model, the outermost set of the connecting screw and the connecting nut is connected to the first mounting plate and the second mounting plate respectively to serve as a disassembly mechanism.

[0015] As a preferred technical solution of this utility model, both the first clamping plate and the second clamping plate are arc-shaped structures, and the inner wall of the second clamping plate is fitted with a protective pad for protecting the cable.

[0016] As a preferred technical solution of this utility model, the limiting component includes a first support plate and a second support plate fixed in an L-shape on a first clamping plate, and a first limiting rod is passed through the interior of the first support plate, and a spring is nested on the outer surface of the first limiting rod, and an anti-slip sleeve is connected to the top of the first limiting rod, and a second limiting rod is vertically fixed on the upper surface of the second support plate.

[0017] As a preferred embodiment of this utility model, the first limiting rod is connected to the first support plate by a spring in a sliding manner.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the adjustable power tower cable fixing device can adjust and clamp the cable during use, and can protect the cable after clamping to prevent it from being clamped too tightly and causing damage to the cable. In addition, the reinforcement device can be disassembled during high-altitude operations, which is convenient for aerial operations.

[0019] Four sets of second clamping plates are equally spaced on the inner side of the first clamping plate, and the upper and lower corresponding second clamping plates are connected to the limiting component. The outer ends of the second clamping plates are connected to the threaded limiting rods through bearings. By rotating the threaded limiting rods, the threaded limiting rods move inside the first clamping plate, thereby moving the first clamping plate and the second clamping plate. The movement of the second clamping plates limits the two sides of the cable inside the first clamping plate. The four sets of second clamping plates equally spaced on the inner side of the first clamping plate clamp the cable to the inner side of the second clamping plate. Then, the first and second reinforcing plates are horizontally connected to the outer side of the cable. Since both the first mounting plate and the second mounting plate are connected to the connecting component through reinforcing bolts, the reinforcing bolts include connecting screws that pass through the connecting component, and connecting nuts are threaded on the outer surface of the connecting screws. The connecting screws pass through the outer surfaces of the first and second reinforcing plates, and the connecting nuts are rotated to move the connecting nuts on the outer surface of the connecting screws, thereby installing the first and second reinforcing plates.

[0020] The connecting screws and nuts are connected to the first and second mounting plates respectively at their outermost ends. The connecting screws then pass through the interiors of the first and second mounting plates. By rotating the connecting nuts, the first and second mounting plates can be easily installed with the first and second reinforcing plates. When disassembly is required, since the first and second mounting plates are connected to the tower, rotating the outermost connecting screws and nuts on the connecting assembly will disengage the first and second mounting plates from the first and second reinforcing plates, allowing for easy disassembly. This facilitates operation from the air and is convenient.

[0021] When the cable is placed inside the second clamping plate, the second clamping plate at the top of the cable automatically adheres to the surface of the cable under the extension and contraction of the spring. At this time, the extension and contraction of the spring causes the first limiting rod to slide inside the first support plate. After the spring extends and contracts, the top of the first limiting rod is connected to an anti-slip sleeve, which is then snapped onto the outer surface of the first limiting rod, so that the anti-slip sleeve adheres to the upper surface of the first support plate. This facilitates adjustment and limiting, preventing the spring from extending and contracting arbitrarily. At the same time, the spring setting can prevent the cable from being limited too tightly, causing damage to the cable. The second limiting rod is vertically fixed on the upper surface of the second support plate, and the lower end of the cable is supported by the second limiting rod through the second support plate.

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-6This utility model provides a technical solution: an easily adjustable power tower cable fixing device. Specifically, as shown in the figure, when it is necessary to limit the installation of cables on the tower, a connecting component is provided on the inner side of the first mounting plate 1, and a second mounting plate 4 is provided on the lower side of the connecting component. The connecting component includes a first reinforcing plate 2 and a second reinforcing plate 3, and both the first reinforcing plate 2 and the second reinforcing plate 3 have first clamping plates 8 on their inner sides. Four sets of second clamping plates 9 are provided at equal angles on the inner side of the first clamping plate 8. The cable is clamped to the inner side of the second clamping plates 9. Then, the first reinforcing plates 2 and the second reinforcing plates 3 are horizontally connected to the outer side of the cable. Since both the first mounting plate 1 and the second mounting plate 4 are connected to the connecting component by reinforcing bolts, the reinforcing bolts include connecting screws 5 penetrating inside the connecting component, and connecting nuts 6 are threaded on the outer surface of the connecting screws 5. The connecting screws 5 are then inserted through the first reinforcing plate 2. The first reinforcing plate 2 and the second reinforcing plate 3 are installed by rotating the connecting nut 6 on the outer surface of the connecting screw 5. After installation, the first mounting plate 1 and the second mounting plate 4 are hung on the tower at appropriate positions. The outermost set of the connecting screw 5 and the connecting nut 6 are connected to the first mounting plate 1 and the second mounting plate 4 respectively. The connecting screw 5 passes through the interior of the first mounting plate 1 and the second mounting plate 4 respectively. The same operation is performed by rotating the connecting nut 6, which facilitates the installation of the first mounting plate 1 and the second mounting plate 4 with the first reinforcing plate 2 and the second reinforcing plate 3. When disassembly is required, since the first mounting plate 1 and the second mounting plate 4 are connected to the tower, the outermost connecting screw 5 and the connecting nut 6 on the rotating connecting assembly are rotated to detach the first mounting plate 1 and the second mounting plate 4 from the first reinforcing plate 2 and the second reinforcing plate 3, thus facilitating disassembly. This allows for convenient operation by personnel in the air.

[0031] As shown in the diagram, after the cable is clamped inside the second clamping plate 9, the first reinforcing plate 2 and the second reinforcing plate 3 are arranged in an arch-like configuration. The corresponding upper and lower second clamping plates 9 are connected to the limiting assembly, and the outer end of the second clamping plate 9 is connected to the threaded limiting rod 7 via a bearing. By rotating the threaded limiting rod 7, the threaded limiting rod 7 moves inside the first clamping plate 8, thereby moving the first clamping plate 8 and the second clamping plate 9. The movement of the second clamping plate 9 limits the cable on both sides inside the first clamping plate 8, facilitating adjustment and limiting for different types of cables. The inner wall of the second clamping plate 9 is fitted with a protective pad 10 for protecting the cable. When the second clamping plate 9 moves, the protective pad 10 contacts the cable, thus protecting the cable. Since the outer side of the first clamping plate 8 is provided with a limiting assembly, the limiting assembly includes a first support plate 11 and a second support plate 15 fixed in an L-shape on the first clamping plate 8. A first limiting rod 12 runs through the interior of plate 11, and a spring 13 is nested on the outer surface of the first limiting rod 12. When the cable is placed into the inner end of the second clamping plate 9, the second clamping plate 9 at the top of the cable automatically adheres to the surface of the cable under the extension and retraction of the spring 13. At this time, the extension and retraction of the spring 13 causes the first limiting rod 12 to slide inside the first support plate 11. After the spring 13 extends and retracts, an anti-slip sleeve 14 is connected to the top of the first limiting rod 12. The anti-slip sleeve 14 is then snapped onto the outer surface of the first limiting rod 12, so that the anti-slip sleeve 14 adheres to the upper surface of the first support plate 11, which facilitates the adjustment and limiting of the cable, preventing the spring 13 from extending and retracting arbitrarily. At the same time, the spring 13 is designed to prevent the cable from being limited too tightly, which could damage the cable. A second limiting rod 16 is vertically fixed on the upper surface of the second support plate 15. The lower end of the cable is supported by the second limiting rod 16 through the second support plate 15. This is the usage method of this easy-to-adjust power tower cable fixing device.
