Description

Technical Field

[0001] This invention relates to the field of cable and wire accessories technology, and more particularly to a roller-type fixing bracket for power equipment conductors. Background Technology

[0002] Fittings, a term widely used in the power industry, refers to accessories made of metals such as iron or aluminum. In high-voltage power transmission, the performance and stability of fittings directly affect the safety and efficiency of the entire system. In current power equipment configurations, the fixing fittings on conductor support insulators typically use aluminum caps. These caps firmly secure the conductors to the 35kV busbar support insulators, effectively ensuring the stability and continuity of power transmission. However, this design has significant drawbacks in practical applications, especially in northern regions. The climate in northern regions is characterized by large temperature differences between winter and summer, causing thermal expansion and contraction in metal and insulator materials. For conductors, due to their material properties and the effects of thermal expansion and contraction, their sag changes with temperature. This change in sag not only affects the stability of the conductor but also generates additional stress on the support insulator. When the conductor sag changes significantly, the stress on the support insulator also increases accordingly. This continuous stress accumulation may lead to insulator breakage. Once the insulator breaks, serious faults such as single-phase grounding and phase-to-phase short circuits may occur. This would not only disrupt power transmission and potentially damage surrounding equipment and buildings, but more importantly, it would affect the production of vital resources such as oil and gas, resulting in huge economic losses. Summary of the Invention

[0003] (a) Technical problems to be solved This invention provides a roller-type fixing bracket for power equipment conductors to overcome the problem in the prior art where the temperature difference between summer and winter in northern regions causes changes in the sag of power equipment conductors, resulting in the breakage of the conductor support porcelain insulator due to stress.

[0004] (II) Technical Solution To achieve the above objectives, the present invention provides a roller-type fixing bracket for power equipment conductors, comprising: a base, two pulleys, and two brackets; The two supports include: a first support and a second support, the two supports are symmetrically arranged on the base, and the first support is located to the left of the second support; The bracket is a rectangular structure, with longitudinal adjustment bolt mounting holes and bolt mounting holes on the outer wall of the bracket, and reinforcing ribs on both sides of the bracket. The adjusting bolt mounting hole is located directly above the bolt mounting hole, and the adjusting bolt mounting hole is a rounded rectangular through hole; The base is a circular structure and has several outwardly extending mounting holes. The two pulleys include a first pulley and a second pulley, which are respectively disposed between two supports. The first pulley is located directly above the second pulley, and rolling bearings are embedded on both sides of the pulleys.

[0012] (III) Beneficial Effects This invention provides a power equipment conductor roller fixing bracket, which allows for convenient installation in the desired position via mounting holes on the base.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] like Figure 1-3 As shown, the present invention provides a roller-type fixing bracket for power equipment conductors, comprising: a base 3, two pulleys 2 and two brackets 1; The bracket 1 has a rectangular structure with rounded corners at the top to reduce the risk of accidental bumps and injuries to the user during operation. The two brackets include a first bracket and a second bracket, symmetrically positioned on the base 3. The first bracket is located to the left of the second bracket. The bracket 1 has longitudinally arranged adjusting bolt mounting holes 8 and 9. Reinforcing ribs are provided on both sides of the bracket 1, effectively improving its bending and torsional resistance, thus extending its service life. The adjusting bolt mounting hole 8 is located directly above the bolt mounting hole 9. The adjusting bolt mounting hole 8 is a rounded rectangular through hole, and the bolt mounting hole 9 is a circular through hole. The adjusting bolt mounting hole 8 is used to adjust the distance between the centers of the two pulleys 2. The power equipment conductor roller type fixing bracket also includes two fixing bolts 5 and two locking nuts 4. The two fixing bolts 5 include a first fixing bolt and a second fixing bolt. The two locking nuts 4 include a first locking nut and a second locking nut. The first fixing bolt is located in the adjusting bolt mounting hole 8, and the second fixing bolt is located in the bolt mounting hole 9. The first fixing bolt passes through the second bracket, the first pulley and the first bracket in sequence and is positioned by the first locking nut. The second fixing bolt passes through the second bracket, the second pulley and the first bracket in sequence and is positioned by the second locking nut.

[0018] The base 3 has a circular structure and is provided with several outwardly extending base mounting holes 7. The base mounting holes 7 are used to install the fixing bracket for the wire roller of the power equipment. The two pulleys 2 include a first pulley and a second pulley. The two pulleys 2 are located between two supports 1. The first pulley is located directly above the second pulley. Rolling bearings 6 are respectively provided on both sides of the pulleys 2. The outer wall of the rolling bearing 6 is fixedly embedded in the pulley 2, and the inner wall of the rolling bearing 6 is tightly attached to the fixing bolt 5. The rolling bearing 6 enables the pulley 2 to maintain balance when rotating on the fixing bolt 5. The function of the rolling bearing 6 is to reduce the friction between the pulley 2 and the fixing bolt 5, so that the pulley 2 rotates more smoothly. The rolling bearing 6 improves the operating efficiency of the entire device. The pulley 2 is made of high-quality aluminum alloy, ensuring its lightweight, sturdiness, and durability. The outer wall of the pulley 2 is equipped with a U-shaped track, which effectively limits the movement of the power equipment wires. The shape of the U-shaped track effectively guides and constrains the wire's direction, preventing entanglement, derailment, or wear during sliding. When the power equipment wire passes through the pulley 2, it is placed within the U-shaped track. Because the two side walls of the U-shaped track are in close contact with the outer wall of the pulley 2, the wire is restricted by the side walls of the U-shaped track as it passes through, allowing it to slide only along a predetermined path. This ensures the stability of the wire during transmission and reduces the risk of the wire deviating from its normal trajectory. The U-shaped track design also helps reduce the contact area between the wire and the pulley 2, thereby reducing the heat that may be generated during the wire's sliding and improving the overall safety performance of the device.

[0019] The following is a detailed description of the actual working scenario of the roller-type fixing bracket for power equipment conductors.

[0020] In practical work, the original pressure cap type wire fixing hardware is replaced with roller type fixing bracket for power equipment wires. During installation, the power equipment wire passes through the U-shaped track on the outer wall of the two rollers. When the sag of the power equipment wire changes, the power equipment wire moves freely between the two U-shaped tracks. This not only fixes the power equipment wire, but also ensures that the supporting porcelain insulator is not affected by the tension of the wire, thereby avoiding the breaking of the supporting porcelain insulator due to excessive tension, which would cause power system failure.

[0021] The conductor roller-type fixing bracket for power equipment has been installed and used in 20 substations. Even with foundation deformation, no damage was observed to the conductor support insulators, and the busbars were unaffected. The use of this new fixing bracket has achieved excellent results, effectively reducing accidental power outages and unplanned shutdowns caused by the aforementioned faults. Due to the application of the conductor roller-type fixing bracket, we successfully avoided significant direct power loss and indirect economic losses related to crude oil production, reducing accidental power outages and unplanned shutdowns caused by the aforementioned faults, thereby reducing direct power loss and indirect economic losses related to crude oil production by approximately 2.7 million yuan.

[0022] It is understood that the various embodiments mentioned above in this invention can be combined with each other to form combined embodiments without violating the principle and logic. Due to space limitations, this invention will not elaborate further.

[0023] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0024] The power equipment conductor roller fixing bracket provided by this invention allows for convenient installation in the required position via the base mounting hole 7 provided in the base 3. The power equipment conductor roller fixing bracket is equipped with two pulleys 2, namely a first pulley and a second pulley. The function of the two pulleys 2 is to allow the power equipment conductor to move freely when the sag of the power equipment conductor changes, so as to avoid the pulling force on the porcelain insulator of the supporting conductor and thus prevent the porcelain insulator of the supporting conductor from breaking. Rolling bearings 6 are respectively provided on both sides of the first pulley and the second pulley, so that the pulley 2 can maintain good balance when rotating. The use of rolling bearings 6 reduces the frictional resistance when the pulley 2 rotates, making the power equipment conductor pass through the pulley 2 more smoothly, thereby reducing unplanned outages of substations and reducing production damage caused by faults.
