Description

Technical Field

[0001] The present invention relates to the technical field of power tools, and particularly relates to a cable support bracket structure for a power transmission tower with anti-dropping function. Background Art

[0002] In power transmission towers, cable support brackets are widely used to support and fix various power cables, including high-voltage transmission lines, low-voltage distribution lines, etc. Through reasonable layout and design, the support brackets can ensure the stability and safety of the cables during transmission, and at the same time reduce the risk of failures caused by cable loosening or dropping. The cable support brackets for power transmission towers usually consist of multiple components, including a bottom plate, brackets, clamping rods, fixing rings, etc. These components are combined together through specific connection methods (such as bolt connection, welding, etc.) to form a stable support structure.

[0003] During the use of traditional cable support brackets for power transmission towers, due to the action of wind, the tower will be subjected to dynamic loads, resulting in vibrations. At the same time, the power transmission line will also generate certain vibrations during the power-on process. These vibrations will be transmitted to the cable support brackets, causing the support brackets to vibrate as well. The vibrations will cause the fixing bolts to loosen, reducing the structural stability of the cable support brackets, resulting in poor contact between the tower and the cables, increasing the resistance, causing power loss, reducing the power transmission efficiency, and further affecting the stability of power supply. Summary of the Invention

[0004] The purpose of the present invention is to provide a cable support bracket structure for a power transmission tower with anti-dropping function to solve the defect of poor anti-dropping effect of the existing cable support bracket structure for power transmission towers.

[0005] To solve the above technical problems, the present invention provides the following technical solution: A cable support bracket structure for a power transmission tower with anti-dropping function, including a bottom plate and brackets installed on both sides of the top end; one end of the top of the bottom plate is connected with a connecting rod, and fixing plates are installed at the ends of both the connecting rod and the brackets. A reinforcing shaft is installed between the bottom plates. One end of the bottom of the bottom plate is installed with a fixing structure, and an anti-dropping structure is arranged on one side of the fixing structure; the anti-dropping structure includes a lower fixing ring, an upper fixing ring, a connecting plate, a pulling plate, a movable plate, a connecting shaft, a hanging ring and a fixing ring; the upper fixing ring is installed at the bottom of the connecting piece. The lower fixing ring is arranged at the bottom of the upper fixing ring. Movable plates are installed at both ends of the lower fixing ring and the upper fixing ring. Connecting plates are installed on one side of each movable plate. Pulling plates are installed at the opposite ends of the connecting plates and the movable plates. Connecting shafts are arranged between the pulling plates. Hanging rings are installed on one side of each pulling plate, and fixing rings are fixed at one end of the bottom plate at the top of the hanging rings.

[0006] Preferably, connecting pieces are arranged on both sides of the bottom end of the bottom plate, and the connecting pieces are installed with the anti-dropping structure and the fixing structure through bolts.

[0007] Preferably, the fixing structure includes an upper hoop, a lower hoop, fixing blocks, screws and movable grooves. The upper hoop is installed at the bottom of the connecting piece, the lower hoop is installed at the bottom of the upper hoop, and screws are arranged on both sides of the upper hoop and the fixing blocks.

[0008] Preferably, fixing blocks are arranged inside both the upper hoop and the lower hoop, and movable grooves are arranged inside both the upper hoop and the lower hoop.

[0009] Preferably, rubber pads are arranged on the inner walls of the fixing blocks, locking grooves are arranged at one ends of the fixing blocks, and contraction springs are installed between the locking grooves and the movable grooves.

[0010] Preferably, locking columns are installed inside the locking grooves and are threadedly connected to the locking grooves, and limiting pieces are arranged at one ends of the locking columns.

[0011] Preferably, limiting grooves are arranged inside the movable grooves outside the limiting pieces, and the inner diameter of the limiting grooves is larger than the outer diameter of the limiting pieces. The cooperation between the limiting grooves and the limiting pieces can prevent the locking columns from disengaging from the locking grooves.

[0012] Preferably, fixing holes are arranged on both sides of the upper hoop and the lower hoop outside the screws, and the screws penetrate through the fixing holes. Through the cooperation between the fixing holes and the screws, the upper hoop and the lower hoop are fixed together.

[0013] Preferably, spring pieces are arranged outside the screws, and nuts are installed at the tops of the spring pieces. The nuts are threadedly connected to the screws. When the spring pieces are under pressure, they will generate elastic force, and the elastic force can keep the nuts and the screws in close fit, effectively preventing loosening caused by vibration or temperature change and increasing the stability of the structure.

[0014] Preferably, rubber pads are arranged on the inner walls of the lower fixing ring and the upper fixing ring. The width of the lower fixing ring is greater than that of the upper fixing ring, and both the movable plate and the pulling plate are triangular. When pulling to one side, the lower fixing ring can move up more symmetrically, avoiding a large misalignment phenomenon when the lower fixing ring and the upper fixing ring are combined.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: in the process of using this cable support bracket structure of the power transmission tower, when it shakes due to strong wind, the greater the pulling force at the pulling ring, the greater the locking force between the fixing rings, thereby achieving the effect of preventing the cable from falling off. Moreover, through the fixing blocks arranged inside the hoop, cables with various diameters can be fixed. At the same time, springs are arranged at the joints, which can effectively prevent loosening and increase the stability of the structure;

[0016] By setting an anti - detachment structure, the cable passes through the inside of the lower fixing ring and the upper fixing ring. Through the pulling force generated by pulling the hanging ring, the lower fixing ring is driven to continuously approach the upper fixing ring, squeezing the cable at the middle position. In strong wind weather, there will be shaking, and the greater the shaking, the greater the pulling force generated at the hanging ring, and the greater the force for the lower fixing ring to approach the upper fixing ring. Thus, the cable support structure of the power transmission tower has an effect of self - locking, realizing the function of anti - detachment and ensuring the stability of the structure;

[0017] By setting a fixing structure, the cable passes through the inside of the upper hoop and the lower hoop, and they are locked and combined through screws. There are spring washers on the screws, which will generate elastic force when under pressure. This elastic force can keep the connection in close fit, preventing loosening caused by vibration or temperature change. At the same time, when the vibration of the transmission line is transmitted to the support bracket, the spring washers can absorb part of the vibration energy and enhance the stability of the connection;

[0018] Furthermore, fixing blocks are arranged inside the upper hoop and the lower hoop. The fixing blocks can be pushed to approach inward by rotating the locking column, fixing and limiting the cable in the middle, so as to realize the clamping and fixing of cables with different sizes and increase the applicability of the support bracket.

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1 - 10, a cable support bracket structure for preventing the shedding of a power transmission tower provided by the present invention includes a bottom plate 1 and brackets 2 installed on both sides of the top end; one end of the top of the bottom plate 1 is connected to a connecting rod 3, and fixing pieces 6 are installed at the ends of both the connecting rod 3 and the brackets 2. A reinforcing shaft 5 is installed between the bottom plates 1. A fixing structure 4 is installed at one end of the bottom of the bottom plate 1. Connecting pieces 8 are provided on both sides of the bottom end of the bottom plate 1, and the connecting pieces 8 are installed with the anti-shedding structure 7 and the fixing structure 4 through bolts respectively. The fixing structure 4 includes an upper hoop 41, a lower hoop 42, a fixing block 43, a screw 44 and a movable groove 45. The upper hoop 41 is installed at the bottom of the connecting piece 8, and the lower hoop 42 is installed at the bottom of the upper hoop 41. Screws 44 are provided on both sides of the upper hoop 41 and the fixing block 43. Fixing blocks 43 are provided inside both the upper hoop 41 and the lower hoop 42. Movable grooves 45 are provided inside both the upper hoop 41 and the lower hoop 42. Rubber pads are provided on the inner walls of the fixing blocks 43. Locking grooves 432 are provided at one ends of the fixing blocks 43, and compression springs 433 are installed between the locking grooves 432 and the movable grooves 45. Locking columns 431 are installed inside the locking grooves 432, and the locking columns 431 are threadedly connected with the locking grooves 432. Limiting pieces 434 are provided at one ends of the locking columns 431. Limiting grooves 435 are provided inside the movable grooves 45 outside the limiting pieces 434, and the inner diameter of the limiting grooves 435 is larger than the outer diameter of the limiting pieces 434. Fixing holes 442 are provided on both sides of the upper hoop 41 and the lower hoop 42 outside the screws 44, and the screws 44 penetrate through the inside of the fixing holes 442. Spring pieces 443 are provided outside the screws 44, and nuts 441 are installed at the tops of the spring pieces 443. The nuts 441 are threadedly connected with the screws 44;

[0032] Refer to Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, when the device is in use, after installing the bottom plate 1 on the iron tower, the upper clamp 41 is fixed to the connecting piece 8 through bolts. There are multiple groups of connecting pieces 8, and multiple groups of cables can be installed simultaneously. Then, the lower clamp 42 is placed at the bottom of the upper clamp 41. The screw 44 passes through the fixing holes 442 on both sides of it, and then the spring piece 443 and the nut 441 are sleeved in sequence. Rotate the nut 441 to continuously move downward on the screw 44. Before locking, pass the cable through the space between the lower clamp 42 and the upper clamp 41, and then continue to rotate the nut 441 to lock. At the same time, there is a spring piece 443 between the nut 441 and the upper clamp 41. In the locked state, the spring piece 443 generates a certain elastic force under pressure, effectively preventing loosening caused by vibration or temperature changes. If the diameter of the cable is too small, the locking column 431 can be rotated to push the fixing block 43 to squeeze inwards. The locking column 431 is threadedly connected to the locking groove 432, so as to realize the movement of the fixing block 43. At the same time, the contraction spring 433 arranged between the locking groove 432 and the movable groove 45 can generate a pre-tightening force between the fixing block 43 and the limiting piece 434 through elasticity after pushing the fixing block 43 to move. The surface of the limiting piece 434 is made of rubber anti-slip material, which can prevent the locking column 431 from loosening and causing connection failure;

[0033] On one side of the fixing structure 4, there is an anti-detachment structure 7; the anti-detachment structure 7 includes a lower fixing ring 71, an upper fixing ring 72, a connecting plate 73, a pulling plate 74, a movable plate 75, a connecting shaft 76, a hanging ring 77 and a fixing ring 78; the upper fixing ring 72 is installed at the bottom of the connecting piece 8. The lower fixing ring 71 is arranged at the bottom of the upper fixing ring 72. At both ends of the lower fixing ring 71 and the upper fixing ring 72, movable plates 75 are installed. On one side of each movable plate 75, a connecting plate 73 is installed. At the opposite ends of the connecting plate 73 and the movable plate 75, pulling plates 74 are installed. A connecting shaft 76 is arranged between the pulling plates 74. On one side of each pulling plate 74, a hanging ring 77 is installed. At one end of the bottom plate 1 at the top of the hanging ring 77, a fixing ring 78 is fixed. Rubber pads are arranged on the inner walls of the lower fixing ring 71 and the upper fixing ring 72. The width of the lower fixing ring 71 is greater than that of the upper fixing ring 72. The movable plates 75 and the pulling plates 74 are both triangular in shape;

[0034] Refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 10As shown, when the device is in use, after the cable is installed between the fixed structure 4, the cable is passed through the lower fixing ring 71 and the upper fixing ring 72, and then the hanging ring 77 is pulled upward to the top. The hanging ring 77 is engaged and fixed with the fixing ring 78, so that the pulling plate 74 moves to one side. The bottom of the movable plate 75 is driven by the connecting shaft 76 connected thereto to incline to one side. Since the movable plate 75 is triangular, when it inclines, the lower fixing ring 71 is driven to approach the upper fixing ring 72, and the cable between the lower fixing ring 71 and the upper fixing ring 72 is clamped. When there is a strong wind, the greater the shaking generated, the greater the tension at the hanging ring 77, so that the pulling plate 74 drives the movable plate 75 to have a greater inclination angle, and thus the locking force of the lower fixing ring 71 approaching the upper fixing ring 72 is greater, achieving the effect of preventing the cable from falling off.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
