Description

Technical Field

[0001] This utility model relates to the field of street code technology, and in particular to a high-toughness support insulator street code. Background Technology

[0002] In the construction and operation of power transmission and distribution lines, insulators are often used as isolation and fixing components between conductors and supporting structures. The term "street bracing" typically refers to an installation structure used to support insulators and related cables. Its main function is to form reliable support and buffer between the cable and supporting components, thereby ensuring the stable operation of the line. Street bracing generally consists of a mounting plate, rotating frame, support rod, and pulleys. By installing pulleys on it, the cable can be fixed and guided with minimal friction. Furthermore, considering that the line is in an outdoor environment for extended periods, street bracing not only needs a certain level of mechanical strength but also high toughness to withstand stresses from external wind, impacts, or changes in cable tension, thus preventing damage to supporting components or insulator failure.

[0003] However, existing support insulator brackets still have some problems that need to be solved during use. First, after installation, the position of the pulleys in contact with the cable is usually fixed, lacking adaptive adjustment. When the bracket is impacted by external force, the pulleys cannot adaptively adjust their angle according to the cable stress, which easily causes damage to the pulleys and reduces the service life of the overall device. Second, the installation angle of the pulleys is also usually fixed during installation. When the mounting surface of the bracket is tilted, the pulleys are also tilted and cannot be corrected, resulting in poor applicability in different installation environments and seriously affecting the cable stress balance and operational safety.

[0004] Furthermore, we disclose a high-toughness support insulator street code to meet the practical needs of insufficient applicability caused by the lack of adaptive adjustment of pulleys and fixed installation angles in existing technologies. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a high-toughness support insulator street code to solve the problem of insufficient applicability caused by the lack of adaptive adjustment of pulleys and fixed installation angle in the existing technology.

[0006] To achieve the above objectives, this utility model provides a high-toughness support insulator street code, comprising a mounting plate, a rotating frame rotatably connected to one side of the upper end of the mounting plate, a plurality of support seats fixedly connected at even intervals to the upper end of the rotating frame, a sliding seat slidably connected inside each of the plurality of support seats, a telescopic spring fixedly connected to the lower end of each sliding seat, the lower end of the telescopic spring being fixedly connected to the mounting plate, a support rod fixedly connected to the upper end of each of the plurality of sliding seats, a pulley sleeved on the outside of each support rod between two adjacent sliding seats, an adjustment component provided on the mounting plate, the adjustment component being used to adjust the rotation angle of the rotating frame on the mounting plate, and an adaptive module provided at the connection between the pulley and the support rod, the adaptive module being used to cause the pulley to rotate on the support rod.

[0007] Preferably, the adjustment assembly includes a rotating seat fixedly connected to one side of the upper surface of the mounting plate, the lower end of the rotating frame being rotatably connected to the rotating seat, and a support being fixedly connected to the upper surface of the mounting plate away from the rotating seat.

[0008] Preferably, a transmission rod is rotatably connected to the middle of the support, the transmission rod has a spiral groove in the middle and is connected to a transmission plate, the lower end of the transmission plate is slidably connected to the upper end of the mounting plate, and connecting seats are fixedly connected to both sides of the upper end surface of the transmission plate, and rollers are rotatably connected to the upper ends of the two connecting seats.

[0009] Preferably, a top plate is fixedly connected to both sides of the upper end of the inner top surface of the rotating frame, and the lower end surface of the top plate is inclined and in contact with the outer wall of the roller.

[0010] Preferably, the end of the transmission rod away from the support is rotatably connected to the rotating seat, and the end of the transmission rod away from the rotating seat is provided with a turntable and a crank.

[0011] Preferably, the pulley is hollow and has an anti-slip groove in the middle. Multiple reinforcing rods are fixedly connected at even intervals inside the pulley, and the reinforcing rods are arc-shaped.

[0012] Preferably, the adaptive module includes a ball sleeve located in the middle of the pulley, a ball head located at the connection point on the support rod corresponding to the pulley, the ball sleeve being fitted onto the ball head, and a reset module located on both sides of the inner wall of the ball sleeve. The reset module is used to keep the axis of the pulley coincident with the axis of the support rod.

[0013] Preferably, the reset module includes a plurality of reset springs fixedly connected to both sides of the inner wall of the ball sleeve at uniform angular intervals. One end of each reset spring is fixedly connected to an abutment plate. A ball joint is provided at the end of the abutment plate away from the reset spring. A support plate is provided on the side of the ball joint away from the abutment plate. The support plate is arc-shaped and fits against the outer wall of the support rod.

[0014] The beneficial effects of this utility model are: This high-toughness support insulator street code utilizes a ball-head-ball-sleeve adaptive module at the connection between the support rod and the pulley, combined with a return spring and support plate, to allow the pulley to fine-tune and rotate when subjected to external impact or load shift, preventing the roller from being directly damaged by impact. Compared to existing designs where the roller is fixed and cannot be adjusted, this effectively absorbs external impact, improving the durability and safety of the roller and the overall street code.

[0015] This high-toughness support insulator street code, through the adjustment components including the rotating seat, transmission rod, transmission plate, and the cooperation of rollers and inclined top plate, can precisely adjust the angle of the rotating frame on the mounting plate, so that the pulley always remains parallel to the cable or in optimal contact. Compared with the existing technology where the roller installation angle is fixed and the roller tilt cannot be adjusted when the mounting surface is tilted, this can adapt to different tilt angle installation environments and ensure that the street code can operate stably under various working conditions.

[0016] This high-toughness support insulator street block uses a sliding seat and telescopic spring design to achieve elastic displacement and buffering function of the support rod under external force. At the same time, the hollow design of the pulley and the internal arc-shaped reinforcing rod improve the overall compressive and torsional strength of the roller and support structure. This design effectively solves the problem of stress concentration and easy damage caused by excessive rigidity of the fixed structure in the existing technology, giving the entire street block high toughness, long service life and stable operation capability.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1 to 6 As shown, a high-toughness support insulator street code includes a mounting plate 1. A rotating frame 2 is rotatably connected to one side of the upper end of the mounting plate 1. Multiple support seats 3 are fixedly connected at even intervals to the upper end of the rotating frame 2. Sliding seats 4 are slidably connected inside the multiple support seats 3. A telescopic spring 9 is fixedly connected to the lower end of the sliding seat 4. The lower end of the telescopic spring 9 is fixedly connected to the mounting plate 1. A support rod 6 is fixedly connected to the upper end of the multiple sliding seats 4. A pulley 5 is sleeved on the outside of the support rod 6 between two adjacent sliding seats 4. An adjustment component is provided on the mounting plate 1 to adjust the rotation angle of the rotating frame 2 on the mounting plate 1. An adaptive module is provided at the connection between the pulley 5 and the support rod 6 to make the pulley 5 rotate on the support rod 6. The adjustment component is used to adjust the rotation angle of the rotating frame 2 on the mounting plate 1. By setting this adjustment component, the angle of the rotating frame 2 can be changed under different installation environments or stress conditions, ensuring a reasonable relationship between the pulley 5 and the cable guide or support, thereby improving the overall applicability of the machine. Furthermore, an adaptive module is provided at the connection between the pulley 5 and the support rod 6, specifically a ball joint 12-ball sleeve 11 structure, combined with components such as a return spring 17, allowing the pulley 5 to rotate flexibly on the support rod 6. When external loads or angular deviations cause deflection between the pulley 5 and the support rod 6, the module automatically... The adaptive module allows pulley 5 to rotate within a certain range to reduce local stress concentration. When the external force is released, the reset module can automatically restore pulley 5 to its initial state, thereby ensuring that the axis of pulley 5 is consistent with the axis of support rod 6. This achieves the dual effects of high toughness and self-adaptation. Through the synergistic effect of the above-mentioned overall structure, the modified high-toughness support insulator not only has good load-bearing and buffering performance, but also improves installation flexibility and operational stability through the adjustment components and adaptive module. It is especially suitable for long-term use in variable environments and has significant practical value.

[0023] Furthermore, such as Figures 1 to 6 As shown, the adjustment assembly includes a rotating seat 10 fixedly connected to one side of the upper surface of the mounting plate 1. The lower end of the rotating frame 2 is rotatably connected to the rotating seat 10, allowing the rotating frame 2 to change angle relative to the mounting plate 1 around the rotating seat 10, facilitating subsequent adjustment. A support 7 is fixedly connected to the side of the upper surface of the mounting plate 1 away from the rotating seat 10. A transmission rod 8 is rotatably connected to the middle of the support 7. The transmission rod 8 can rotate stably at the support 7, and a spiral groove is provided in the middle of its outer wall. A transmission plate 19 is engaged within the spiral groove. When the transmission rod 8 rotates, it can drive the transmission plate 19 to slide linearly back and forth along the length of the mounting plate 1. The lower end of the transmission plate 19 is slidably connected to the upper end of the mounting plate 1 to ensure that the transmission plate 19 can maintain guiding stability during linear movement. Both sides of the upper end of the transmission plate 19 are fixedly connected to the connecting seats 20. The upper ends of the two connecting seats 20 are engaged and rotatably connected to the rollers 21. When the rollers 21 rotate, they can reduce the frictional resistance with the top plate 18. The upper sides of the inner top surface of the rotating frame 2 are fixedly connected to the top plate 18. The lower end of the top plate 18 is machined into an inclined surface, and the inclined surface contacts the outer wall of the rollers 21. When the transmission rod 8 rotates and drives the transmission plate 19 to move, the rollers 21 generate a force reaction along the inclined surface, thereby pushing the rotating frame 2 to adjust the angle. In use, the operator only needs to rotate the turntable and crank at the end of the transmission rod 8 away from the support 7 to drive the transmission rod 8 to rotate continuously. This causes the transmission plate 19 to produce linear displacement under the guidance of the spiral groove, and drives the roller 21 to roll along the inclined surface of the top plate 18 through the connecting seat 20. As the roller 21 continuously presses against the lower end surface of the top plate 18, the rotating frame 2 gradually rotates around the rotating seat 10. The roller 21 is in surface contact with the inclined top plate 18. The transmission rod 8 drives the roller 21 to roll along the inclined surface, realizing the conversion of the linear displacement of the transmission plate 19 into the angular displacement of the rotating frame 2 around the rotating seat 10. Through this mechanism, when there is a horizontal deviation or inclination on the mounting surface of the street code, the angle of the rotating frame 2 can be corrected in time to make it form a suitable relative posture with the mounting plate 1, ensuring that the pulley 5 supported on it keeps parallel and in uniform contact with the cable. Therefore, the design of this adjustment component can solve the defects of the existing technology where the roller 21 has a fixed installation angle and cannot be adjusted for different installation environments, significantly improving the installation adaptability and versatility of the street code. At the same time, since the transmission rod 8 transmits force through the cooperation between the spiral groove and the transmission plate 19, the adjustment process is relatively easy and labor-saving. The operator can flexibly control the rotation angle with a crank handle, reducing the need for extensive manual disassembly and assembly, and improving adjustment efficiency. In addition, the roller 21 cooperates with the inclined surface of the top plate 18 to effectively convert the linear motion of the transmission plate 19 into the angle adjustment action of the rotating frame 2. The transmission process is smooth and reliable, avoiding structural jamming or uneven force, thereby improving the service life and operational safety of the overall device.

[0024] Furthermore, such as Figure 3 As shown, the pulley 5 adopts a hollow design, and an annular anti-slip groove is formed on the circumference of its outer wall. This anti-slip groove can increase friction, thereby effectively preventing slippage and ensuring the stability and reliability of the transmission process. In order to further enhance the structural strength of the pulley 5, multiple reinforcing rods 13 are fixedly connected at uniform intervals in the radial direction inside. The reinforcing rods 13 are arc-shaped and can fit with the inner wall of the pulley 5. Without significantly increasing the weight of the pulley 5, the overall compressive and torsional resistance is improved. The arc-shaped reinforcing rods 13 can also form circumferential support for the inner wall of the pulley 5, making the pulley 5 less prone to deformation or cracking during long-term force transmission, thus extending the service life of the whole machine. At the same time, the combination design of the hollow structure and the arc-shaped reinforcing rods 13 not only ensures the stability of the transmission process, but also takes into account the need to reduce weight and energy consumption, and has a good comprehensive effect.

[0025] Furthermore, such as Figures 4 to 5As shown, the adaptive module is located in the middle of the support rod 6. Its core structure is the cooperation between the ball sleeve 11 and the ball head 12. The support rod 6 has a ball head 12 machined at the connection position corresponding to the pulley 5. The outer surface of the ball head 12 is smoothly formed to realize multi-directional rotation. The ball sleeve 11 is fitted on the ball head 12. The two form a universal connection structure of ball head 12-ball sleeve 11. In order to prevent excessive deflection or instability between the ball head 12 and the ball sleeve 11, reset modules are arranged on both sides of the inner wall of the ball sleeve 11 to automatically keep the axis of the pulley 5 and the axis of the support rod 6 in a coincident state. The reset module specifically includes multiple reset springs 17 evenly spaced along the circumference. One end of each reset spring 17 is fixedly connected to the inner wall of the ball sleeve 11, and the other end is fixedly connected to the abutment plate 16. The abutment plate 16 has an arc surface structure, and a ball hinge 15 is installed on the side away from the reset spring 17. The ball hinge 15 is connected to the support plate 14. The support plate 14 is processed into an arc surface and fits against the outer wall of the support rod 6. Through the above structure, when the pulley 5 is subjected to external force, causing the support rod 6 and the ball head 12 to deflect relative to each other, the reset spring 17 will be compressed and deformed, causing the abutment plate 16, the ball hinge 15 and the support plate 14 to move accordingly, thereby realizing the flexible swing of the pulley 5 in multiple angular directions. The reset module undergoes symmetrical compression under external force. After the external force is released, the spring force of the reset spring 17 acts on the support rod 6 through the contact plate 16, ball joint 15, and arc support plate 14, causing the axis of the pulley 5 to automatically return to the center and coincide with the axis of the support rod 6. Through the design of this adaptive module, not only can the swaying problem caused by installation error or uneven load be alleviated, but the running stability of the pulley 5 under complex working conditions can also be improved, effectively reducing wear and jamming risks and extending the service life of the overall mechanism.
