Description

Technical Field

[0001] This utility model relates to the field of sign bracket technology, specifically a fixed bracket for overhead line signs that is easy to install. Background Technology

[0002] Overhead lines, as crucial infrastructure for power transmission and communication, require signage to convey line attributes, safety warnings, and management information to ensure safe operation and standardized management. These signs must be installed at high locations such as poles and crossarms using fixed supports. Existing overhead line signage supports have significant technical shortcomings: traditional supports are mostly simple, one-piece long poles or simple welded frames with limited functionality, only providing basic load-bearing capacity. In daily maintenance, signs require regular inspection and replacement due to environmental erosion, external impacts, or information updates. However, traditional supports lack convenient operating mechanisms, requiring maintenance personnel to climb to reach the signs and perform disassembly, replacement, and re-tightening, resulting in complex and time-consuming procedures and significantly reduced maintenance efficiency. More importantly, climbing significantly increases the safety risks of falls and electric shocks, especially in mountainous areas, complex terrain, or sections with live power lines. Furthermore, traditional supports lack versatility, requiring customization for different specifications, further increasing the cost and difficulty of line signage management.

[0003] Therefore, this utility model provides a fixing bracket for overhead line signs that is easy to install. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5 An easy-to-install overhead line sign fixing bracket includes a supporting hollow main pole 1, a base 11 and a sign 2. A collar 3 is sleeved on the outside of the supporting hollow main pole 1, and an annular traction belt 4 is provided inside the supporting hollow main pole 1 to adjust the height of the collar 3.

[0022] The inner wall of the collar 3 is equipped with a central limiting slide plate 31, and the hollow main rod 1 is provided with a strip-shaped perforation 12. The central limiting slide plate 31 is slidably connected to the inner wall of the strip-shaped perforation 12, and the sign 2 is located on one side of the collar 3.

[0023] It should be noted that the strip-shaped perforation 12 described in this embodiment limits the angle of the centrally positioned limiting slide plate 31 to prevent it from swinging arbitrarily.

[0024] Two pulleys 41 are provided on the inner side of the annular traction belt 4. Both pulleys 41 are rotatably connected to the inner wall of the supporting hollow main rod 1. The two pulleys 41 are distributed in a vertical direction. The annular traction belt 4 passes through the central limiting slide plate 31. Two clamping blocks 42 are installed on the side wall of the annular traction belt 4. The central limiting slide plate 31 is clamped between the two clamping blocks 42.

[0025] It should be noted that the two through holes on the central limiting slide plate 31 described in this embodiment are larger than the diameter of the annular traction belt 4, so that the annular traction belt 4 does not directly contact the central limiting slide plate 31, and the sidewalls of the annular traction belt 4 and the pulley 41 are provided with anti-slip texture.

[0026] Specifically, in use, by rotating the lower pulley 41, the pulley 41 drives the annular traction belt 4 to circulate. The two clamping blocks 42 on the side wall of the annular traction belt 4 move accordingly. Since the central limiting slide plate 31 is clamped between the two clamping blocks 42, and the central limiting slide plate 31 is slidably connected to the inner wall of the strip-shaped perforation 12 on the supporting hollow main rod 1, the strip-shaped perforation 12 limits the angle of the central limiting slide plate 31 to prevent it from swinging arbitrarily. When the annular traction belt 4 moves, it will drive the central limiting slide plate 31 to slide up and down along the strip-shaped perforation 12, thereby making the sleeve... The collar 3 located on the outside of the supporting hollow main rod 1 allows for height adjustment, and the sign 2 on one side of the collar 3 also rises and falls accordingly. This fixed bracket, through the cooperation of components such as the pulley 41 and the annular traction belt 4, can conveniently adjust the height of the collar 3 and the sign 2. Maintenance personnel can complete the maintenance and replacement of the sign 2 from the ground without having to climb up, simplifying the work process, improving maintenance efficiency, and reducing safety risks. At the same time, the structural design of this bracket makes it more versatile, reducing the cost and difficulty of customizing brackets for different specifications.

[0027] In one embodiment of this utility model, such as Figures 1-5 As shown, two drainage holes 13 are provided at the bottom of the hollow main rod 1, and both drainage holes 13 correspond to the positions of the base 11.

[0028] Specifically, the two drainage holes 13 at the bottom of the supporting hollow main rod 1 correspond to the position of the base 11. When water accumulates inside the supporting hollow main rod 1 due to rain, dew or a humid environment, the water can be naturally discharged to the base 11 through these two drainage holes 13, thus preventing water from lingering inside the main rod for a long time.

[0029] In one embodiment of this utility model, such as Figures 1-5 As shown, a folding rocker arm 6 is installed on one side of the lower annular traction belt 4, and the folding rocker arm 6 is rotatably connected to one side of the supporting hollow main rod 1.

[0030] It should be noted that one end of the folding rocker 6 described in this embodiment can be bent away from the supporting hollow main rod 1, making it easier for people to hold.

[0031] Specifically, when the height of the sign 2 needs to be adjusted, the folding rocker arm 6 is bent away from the supporting hollow main rod 1 to make it easier for personnel to grip. Then, the folding rocker arm 6 is rotated. Since the folding rocker arm 6 is connected to the lower annular traction belt 4, rotating the folding rocker arm 6 will drive the corresponding pulley 41 to rotate, thereby driving the annular traction belt 4 to circulate. The annular traction belt 4, through the clamping block 42, drives the centrally positioned limiting slide plate 31 to slide along the strip-shaped perforation 12, ultimately achieving the height adjustment of the collar 3 and the sign 2. The bendable design of the folding rocker arm 6 not only facilitates gripping during operation but also allows it to be folded up when not in use, saving space and making it easy to carry and store.

[0032] In one embodiment of this utility model, such as Figures 1-5 As shown, the inner wall of the folding rocker 6 is threaded with a fixing bolt 61, and a docking port 14 is provided on one side of the supporting hollow main rod 1. The fixing bolt 61 is inserted into the inner wall of the docking port 14.

[0033] Specifically, after the folding rocker 6 is finished using, it is rotated towards the hollow supporting rod 1 to fold it up. Then, the fixing bolt 61 on the inner wall of the folding rocker 6 is rotated to move the fixing bolt 61 towards the hollow supporting rod 1 until the fixing bolt 61 is inserted into the inner wall of the docking socket 14 on the side of the hollow supporting rod 1. This fixes the folding rocker 6 on the hollow supporting rod 1, preventing it from shaking freely when not in use. This achieves the storage and fixation of the folding rocker 6, which saves space and prevents the rocker from being damaged by shaking or causing interference to people.

[0034] In one embodiment of this utility model, such as Figures 1-5 As shown, a mounting bracket 32 ​​is installed on one side of the collar 3, and the sign 2 is detachably connected to one side of the mounting bracket 32.

[0035] Specifically, the mounting bracket 32 ​​installed on one side of the collar 3 provides a mounting carrier for the sign 2, and the sign 2 is detachably connected to one side of the mounting bracket 32. When the sign 2 needs to be inspected, replaced, or its information updated, the sign 2 can be easily removed from the mounting bracket 32. After completing the relevant operations, the sign 2 can be reinstalled on the mounting bracket 32 ​​without the need for complex disassembly and assembly of the entire bracket, which greatly simplifies the maintenance process of the sign 2 and improves the efficiency of operation and maintenance.

[0036] In one embodiment of this utility model, such as Figures 1-5 As shown, a first magnetic plate 33 is installed at the top of the central limiting slide plate 31, and a top plate 5 is installed on the inner wall of the supporting hollow main rod 1. The top plate 5 is located at the bottom of the upper pulley 41. A slot 51 is opened at the bottom of the top plate 5. The first magnetic plate 33 is inserted into the inner wall of the slot 51. A second magnetic plate 52 is installed in the slot 51. The first magnetic plate 33 and the second magnetic plate 52 are magnetically attracted to each other.

[0037] It should be noted that when the collar 3 described in this embodiment drives the sign 2 to rise, the adsorption and docking of the first magnetic plate 33 and the second magnetic plate 52 achieves preliminary positioning, which facilitates the subsequent fixing of the folding rocker 6.

[0038] Specifically, when the collar 3 lifts the sign 2 to the preset height, the central limiting slide plate 31 moves upward synchronously with the collar 3. The first magnetic plate 33 installed at its top gradually approaches the slot 51 at the bottom of the inner wall top plate 5 of the supporting hollow main rod 1, and finally the first magnetic plate 33 is inserted into the inner wall of the slot 51. At this time, the second magnetic plate 52 in the slot 51 and the first magnetic plate 33 are tightly connected through magnetic adsorption, forming a preliminary positioning of the central limiting slide plate 31 and the collar 3, preventing them from sliding down under gravity. This magnetic adsorption positioning method can quickly fix the position of the sign 2 after it is adjusted to the target height, avoiding positional displacement caused by external force or operation pauses during the adjustment process. It provides a stable foundation for the subsequent fixing operation of the folding rocker 6, ensuring that the sign 2 remains highly stable during use and improving the overall reliability of the bracket.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] Working principle: The hollow main rod 1 is fixed by the base 11. The central limiting slide plate 31 on the inner wall of the outer collar 3 is slidably connected to the strip-shaped through hole 12 of the main rod, which restricts its swing. The vertically distributed pulleys 41 inside the main rod support the annular traction belt 4, and the clamping block 42 on the side wall of the traction belt clamps the central limiting slide plate 31. When adjusting the height of the sign 2, the folding rocker 6 is bent and held. Rotating the rocker drives the pulleys 41 and the traction belt to move in a cycle, which drives the central limiting slide plate 31 through the clamping block 42. 1. The lifting mechanism moves synchronously along the perforation, with the collar 3 and the side sign 2 moving in sync. After the sign reaches the preset height, the first magnetic plate 33 at the top of the central limiting slide plate 31 is inserted into the slot 51 of the top plate 5 and magnetically attracted and positioned with the second magnetic plate 52. After use, the rocker arm is retracted and fixed by inserting the fixing bolt 61 into the docking socket 14. The sign 2 is detachably connected via the mounting bracket 32, and the drainage hole 13 at the bottom of the main pole drains accumulated water. This structure enables ground adjustment and maintenance, improves efficiency, reduces safety risks, and enhances versatility and reliability.
