Abstract
Description
Technical Field
[0001] This utility model relates to the field of marking equipment technology, and in particular to a fixing bracket for power tower identification signs. Background Technology
[0002] Power towers are trapezoidal or triangular structures, typically 25-40 meters high, with a steel frame structure. They are mostly built near power plants and substations in the field. They are important facilities for the power sector, providing overhead power lines and serving as protection and support. The design, manufacture, installation, maintenance, and quality inspection of power towers are crucial for the operation and development of modern power systems.
[0003] In recent years, with the rapid growth of the national economy, the power industry has developed rapidly, which has also promoted the rapid development of the power transmission line tower industry. High-voltage power lines are often erected on power towers. In daily life, there have been cases of people being electrocuted and dying while fishing or engaging in other activities. Therefore, warning signs are installed on power towers to serve as a warning. However, the existing methods of installing these signs are simple, mostly using wire or other objects for fixation. Because the signs are exposed to the external environment, they are easily blown away by strong winds in harsh conditions, causing them to loosen and eventually fall off. The fixation of these signs needs further improvement. Utility Model Content
[0004] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a fixed bracket for power tower identification signs.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixing bracket for a power transmission tower sign includes a mounting plate. A limiting cylinder is fixed to the right side of the mounting plate. A connecting column is vertically embedded in the middle of the limiting cylinder. Buffer plates are fixed to the top and bottom of the connecting column. Locking bolts are vertically embedded to the left side of each buffer plate. Guide rods are fixed to the right side of each buffer plate. Buffer springs and adapter plates are nested on the outer sides of each guide rod. An outer frame is fixed to the right side of both adapter plates. An inner rod is horizontally fixed to the lower part of the inner frame. A bidirectional lead screw is horizontally embedded to the upper part of the inner frame. Clamping plates are embedded at both the left and right ends of the inner frame.
[0006] Preferably, the top and bottom of the limiting cylinder are provided with 10-30 limiting holes in an annular shape at equal intervals. The locking bolt in the buffer plate is embedded in the limiting hole, and the cross-sectional area of the locking bolt near the middle of the connecting column is the same as the cross-sectional area of the limiting hole.
[0007] Preferably, the outer wall of the connecting column is in close contact with the inner wall of the limiting cylinder, and the two buffer discs are in close contact with the upper and lower ends of the connecting column near the middle of the connecting column. The limiting cylinder rotates back and forth in the horizontal direction of the connecting column.
[0008] Preferably, buffer springs are nested at both the front and rear ends of the outer side of the guide rod, and the adapter plate is disposed between the two buffer springs.
[0009] Preferably, the two clamping plates are symmetrically arranged at the left and right ends inside the clamping plates, and the bottoms of the two clamping plates are respectively nested at the left and right ends outside the guide rod.
[0010] Preferably, the interior of the clamping plate is provided with limiting grooves of decreasing width at equal intervals from the outside to the inside.
[0011] Preferably, the bidirectional lead screw is embedded above the interior of the two clamping plates, and the outer wall of the bidirectional lead screw is connected to the outer wall of the clamping plates by threads.
[0012] As can be seen from the above technical solution, the beneficial effects of this utility model are: 1. When strong winds blow towards the sign fixed in the outer frame, the sign will rotate clockwise or counterclockwise along the guide rod in the buffer plate via the outer frame, causing the two adapter plates to rotate. By squeezing and pulling the buffer springs on the outside of the guide rods, the force on the sign and the outer frame is buffered, preventing the sign from being blown away or damaged in strong winds. It has good wind resistance and further improves the service life of the sign.
[0013] 2. After the device is fixed on the iron tower, by pushing the buffer plate, the two buffer plates and the connecting column between them rotate clockwise or counterclockwise in the limiting cylinder to adjust the display direction of the sign in the outer frame. It has a high degree of flexibility. When the sign is placed between the outer frames, by turning the double screw, the two clamps move simultaneously to the middle of the outer frame until they are nested at the left and right ends of the sign to limit and fix the sign. It can limit and fix signs of various sizes, with a wider range of applications and more convenient use. Attached Figure Description

[0018] Example 1, refer to Figures 1-5 A fixing bracket for a power tower sign includes a mounting plate 1. The mounting plate 1 has a limiting cylinder 101 fixed to its right side. A connecting column 2 is vertically embedded in the middle of the limiting cylinder 101. A buffer plate 201 is fixed to the top and bottom of the connecting column 2. A locking bolt 202 is vertically embedded to the left side of each buffer plate 201. A guide rod 203 is fixed to the right side of each buffer plate 201. A buffer spring 204 and a transition plate 205 are nested on the outer side of each guide rod 203. An outer frame 3 is fixed to the right side of each transition plate 205. An inner rod 301 is horizontally fixed to the lower part of the inner side of the outer frame 3. A bidirectional screw rod 302 is horizontally embedded to the upper part of the inner side of the outer frame 3. Clamping plates 303 are embedded at both the left and right ends of the inner side of the outer frame 3.
[0019] The top and bottom of the limiting cylinder 101 are both arranged in a circular shape with 10-30 limiting holes at equal intervals. The locking bolt 202 in the buffer plate 201 is embedded in the limiting hole. The cross-sectional area of the locking bolt 202 near the middle of the connecting column 2 is the same as the cross-sectional area of the limiting hole. After the device is fixed on the iron tower, by pushing the buffer plate 201, the two buffer plates 201 and the connecting column 2 between them rotate clockwise or counterclockwise in the limiting cylinder 101, thereby adjusting the display direction of the sign in the outer frame 3, which has a high degree of flexibility. By turning the locking bolt 202 into the limiting hole inside the buffer plate 201, the buffer plate 201 and the connecting post 2 are combined into a whole to prevent the buffer plate 201 from driving the connecting post 2 to rotate in the limiting cylinder 101 when the sign is blown by the wind. The outer wall of the connecting column 2 is in close contact with the inner wall of the limiting cylinder 101, and the two buffer discs 201 are in close contact with the upper and lower ends of the connecting column 2 at the middle part of the connecting column 2. The limiting cylinder 101 rotates back and forth in the horizontal direction of the connecting column 2. The front and rear ends of the guide rod 203 are both nested with buffer springs 204, and the adapter plate 205 is disposed between the two buffer springs 204. When a strong wind blows towards the sign fixed in the outer frame 3, the sign will rotate clockwise or counterclockwise along the guide rod 203 in the buffer plate 201 via the outer frame 3, causing the two adapter plates 205 to rotate. By squeezing and pulling the buffer spring 204 on the outside of the guide rod 203, the force on the sign and the outer frame 3 is buffered, preventing the sign from being blown away or damaged in strong winds. It has good wind resistance and further improves the service life of the sign. When the strong wind stops, the buffer spring 204 pushes and pulls the adapter plate 205 to return to its original shape, thereby causing the adapter plate 205 to pull the outer frame 3 and the sign back to their original positions, without affecting the normal display of the sign in the outer frame 3. Example 2 differs from Example 1 in that, in this example, two clamping plates 303 are symmetrically arranged at the left and right ends inside the clamping plates 303, and the bottoms of the two clamping plates 303 are respectively nested at the left and right ends outside the guide rod 203. The interior of the clamping plate 303 is provided with limiting grooves of progressively decreasing width at equal intervals from the outside to the inside; The progressively decreasing limiting grooves in the clamping plate 303 are used to limit and fix signs of different thicknesses, preventing the signs from becoming loose when they are embedded in the limiting grooves; The double-acting lead screw 302 is embedded in the upper part of the two clamping plates 303, and the outer wall of the double-acting lead screw 302 is connected to the outer wall of the clamping plate 303 by threads; When the sign is placed between the outer frames 3, the two clamps 303 are moved simultaneously to the middle of the outer frame 3 by turning the two-way screw 302 until they are nested at the left and right ends of the sign to limit and fix the sign. This achieves the limitation and fixation of signs of various sizes, making it more applicable and more convenient to use.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
