Description

Technical Field

[0001] The invention relates to the technical field of power towers, in particular to a linear tower hanging point combined hanging bracket. Background Art

[0002] In the power system, the straight tower is an important supporting structure for the transmission line. Its hanging point installation and cable fixing method are directly related to the safe and stable operation of the power grid. Traditional hanging point systems mostly use a single material or a simple structure connection method, such as direct welding or bolt fixing. It is difficult to withstand the external force under extreme weather conditions such as strong winds, and it is easy to cause structural deformation or damage, which not only increases maintenance costs and safety hazards, but also affects power transmission safety. It cannot be quickly disassembled and installed. Once a failure occurs or maintenance is required, a large number of parts often need to be disassembled, which increases the difficulty and cost of maintenance. Traditional brackets usually use simple card slots to limit the cable. Under the influence of external forces such as strong winds, the cable cannot be effectively fixed, which increases the risk of the cable getting stuck in the gap between the rotating frame and the support wheel, affecting the normal operation of the power system. Summary of the invention

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1-3 As shown, an embodiment of the present invention provides a straight tower hanging point combination hanging bracket, including a fixed frame 1 fixed on two load-bearing steel beams of the straight tower, a support plate 2 is fixed on the fixed frame 1, the support plates 2 are connected with supporting diagonal rods 4, the ends of the supporting diagonal rods 4 are connected through a hanging plate 5, the support plates 2 are connected to each other through a supporting cross bar 6, the two supporting diagonal rods 4 and the supporting cross bar 6 form a triangular structure, the supporting diagonal rods 4 and the supporting cross bar 6 include two angle steels, the angle steels are respectively arranged on both sides of the supporting plate 2 and the hanging plate 5 and form a T shape, the bottom end of the hanging plate 5 is fixed with an upper hanging piece 7, the upper hanging piece 7 is connected to an insulator 9 through a lower hanging piece 8, the insulator 9 is connected to a supporting wheel 11 through a rotating frame 10, and the supporting wheel 11 is provided with a groove 12 for the cable to slide.

[0029] During use, the fixing frame 1 and the hanging wire plate 5 are spliced ​​into a hanging frame through the supporting diagonal rod 4 and the supporting cross bar 6. The supporting diagonal rod 4 and the supporting cross bar 6 are formed into a T-shape by the angle steel to increase the bearing capacity of the structure, and the triangular structure is used as the basic frame of the hanging frame, so that the entire hanging frame can withstand greater external forces without being easily deformed or damaged. The hanging wire plate 5 and the fixing frame 1 are fixed to the straight tower in advance by bolts, and the hanging wire plate 5 is fixedly connected with the upper hanging member 7, and then the upper hanging member 7 is connected with the lower connecting member to facilitate the installation of the insulator 9. The rotating frame 10 and the supporting wheel 11 can support the cable through the groove 12, and the cable can be easily adjusted in distance. The fixing frame 1, the hanging wire plate 5, the supporting diagonal rod 4 and the supporting cross bar 6 can be quickly assembled by standard parts such as bolts, which greatly simplifies the installation process and improves the construction efficiency. At the same time, the modular combination method is also convenient for subsequent maintenance and replacement work, reducing maintenance costs.

[0030] like Figure 2 , 3 As shown in Figure 5, the upper hanging member 7 and the lower hanging member 8 both include a hanging frame 13, a hook-shaped member 14 is hinged in the hanging frame 13, a side wall of the upper hanging member 7 is provided with a plurality of slide grooves 15, and the upper hanging member 7 is slidably connected with a sleeve 16 through the slide grooves 15, and the sleeve 16 can be placed between the hanging frames 13 of the upper hanging member 7 and the lower hanging member 8. The sleeve 16 can protect the hook-shaped member 14 of the upper hanging member 7 and the lower hanging member 8, reduce the rust of the hook-shaped member 14, and improve the service life.

[0031] When the upper hanging member 7 and the lower hanging member 8 are clamped and fixed, the hook-shaped member 14 is hung together, and then the sleeve 16 hangs the member 8 downward along the slide groove 15 under the action of gravity, so that the sleeve 16 is sleeved on the upper hanging member 7 and the lower hanging member 8, and the hook-shaped member 14 is limited by the inner side wall of the sleeve 16 to prevent the hook-shaped member 14 from rotating and falling off. When the insulator 9 needs to be removed, the sleeve 16 is moved upward along the slide groove 15 to expose the hook-shaped member 14, and the insulator 9 can be quickly removed by rotating the hook-shaped member 14 in the opposite direction. By hanging the hook-shaped parts 14 together, a firm connection between the upper hanging part 7 and the lower hanging part 8 is ensured, thereby ensuring the stability of the installation of the insulator 9, and the design of the sleeve 16 further enhances the reliability of the connection. By being sleeved on the hook-shaped part 14 to limit it, the hook-shaped part 14 is effectively prevented from rotating or falling off due to external force, thereby improving the safety and reliability of the entire connection structure, reducing failures and maintenance costs caused by unstable connections, and realizing rapid clamping and fixing of the upper hanging part 7 and the lower hanging part 8, thereby improving work efficiency.

[0032] like Figure 4-9As shown in Figures 12 and 13, the hook-shaped member 14 of the lower hanging member 8 is provided with a traction groove 17, the traction groove 17 includes an oblong groove 18, the end of the oblong groove 18 away from the insulator 9 is connected to the limit groove 19, a pin shaft 20 slides in the traction groove 17, the pin shaft 20 is connected to a traction rope 21, and a locking bin 22 is provided on the rotating frame 10, and a locking structure corresponding to the groove 12 is provided in the locking bin 22, and the locking structure includes a guide hole 23, a guide shaft 24 slides in the guide hole 23, and a limitable end of the guide shaft 24 is provided. The limiting part 25 that prevents the cable from sliding out of the groove 12, one end of the limiting part 25 is against the locking chamber 22 through a spring, the end of the traction rope 21 is reversed by a plurality of guide wheels 26 to coincide with the axis of the guide hole 23, the traction rope 21 is fixedly connected to the guide shaft 24, and the side wall of the sleeve 16 is provided with a movable groove 27 for the traction rope 21 to move, when the upper hanging part 7 and the lower hanging part 8 are in the disconnected state, the pin 20 is placed in the limiting groove 19, and the traction rope 21 compresses the spring of the limiting part 25 through the guide shaft 24. The insulator 9 is installed by hoisting. The end of the traction rope 21 can be divided into multiple traction ropes 21, so as to achieve the effect of driving multiple locking structures at the same time.

[0033] In order to prevent the cable from sliding out of the groove 12 under the influence of strong winds and getting stuck in the gap between the rotating frame 10 and the supporting wheel 11 to cause harm, the cable is first placed in the groove 12. During the process of the upper hanging member 7 and the lower hanging member 8 being clamped and fixed, the hook-shaped member 14 rotates and approaches each other, and the oblong groove 18 of the lower hanging member 8 changes from an inclined state to a vertical state, so that the pin shaft 20 slides from the limiting groove 19 into the oblong groove 18 near one end of the insulator 9. At the same time, since the pin shaft 20 drives the traction rope 21 to move downward, the pulling force of the traction rope 21 on the guide shaft 24 is reduced. After the pulling force is reduced, the pressure of the guide shaft 24 on the compression spring through the limiting portion 25 is relatively reduced, so that the compression spring can push the limiting portion 25 to close the groove 12, thereby achieving the effect of fixing the insulator 9 and the cable at the same time. When the rotating frame 10 needs to be disassembled, the pin 20 is manually placed in the limiting groove 19, and the locking structure can be pulled simultaneously by the traction rope 21, so that the cable can freely enter and exit the groove 12. The direction of the locking structure is not restricted. For example, the rotating frame 10 above the groove 12 can be set to make the limiting part 25 slide up and down, and the bottom surface of the limiting part 25 can close the groove 12 and fix the cable. The parts connected to the cable can be provided with an insulating layer or an insulating material. The upper hanging member 7 and the lower hanging member 8 can be connected to the hook-shaped member 14 through a torsion spring. By setting the torsion spring, the position of the hook-shaped member 14 can be relatively determined to prevent the hook-shaped member 14 from swinging arbitrarily and causing inconvenience in clamping and installation. It can also apply a certain torque to the hook-shaped member 14 when the hook-shaped members 14 are clamped and close to each other, ensuring that the hook-shaped members 14 are stably clamped. The locking structure can prevent the cable from sliding out of the groove 12 through the cooperation of the compression spring and the limit part 25, thereby increasing the safety of the cable use, and the cable can be fixed and released while replacing the insulator 9 through the traction rope 21 and the pin 20, thereby simplifying the installation process, improving work efficiency, and reducing the workload of maintenance personnel. In the entire design process, the stability and safety of the cable during the fixing and unlocking process are ensured through the mutual cooperation of multiple mechanical structures.

[0034] like Figure 10-11As shown, the side wall of the upper hanging member 7 is provided with a locking groove 28, and the bottom end of the locking groove 28 is hinged with an upper ratchet bar 29 with a tooth tip facing upward, and the side wall of the sleeve 16 is provided with a lower ratchet bar 30 with a tooth tip facing downward, and the upper ratchet bar 29 and the lower ratchet bar 30 can mesh, and the top of the upper ratchet bar 29 is fixed with an unlocking plate 31 protruding from the locking groove 28, and the unlocking plate 31 is against the locking groove 28 through a locking spring 32, and the side wall of the upper hanging member 7 is provided with a push groove 33, and the push groove 33 is against the top of the sleeve 16 through a thrust spring 34. The lower ratchet bar 30 can make the upper ratchet bar 29 compress the locking spring 32, so that the sleeve 16 can move upward, and when the sleeve 16 is not subjected to external force, the lower ratchet bar 30 is meshed and clamped with the upper ratchet bar 29 to fix the sleeve 16, thereby ensuring the stability of the sleeve 16 during use and reducing the effect of reduced work efficiency caused by the movement of the sleeve 16 hindering installation. When the sleeve 16 needs to be moved downward, the unlocking plate 31 is pressed, and the unlocking plate 31 compresses the locking spring 32, so that the engagement between the lower ratchet bar 30 and the upper ratchet bar 29 is disconnected. At this time, the sleeve 16 moves downward along the slide groove 15 under the action of the thrust spring 34. By setting the upper ratchet bar 29 and the lower ratchet bar 30 that can engage with each other, the sleeve 16 can be quickly fixed, avoiding the need to use other tools or parts to fix the sleeve 16, thereby improving work efficiency. The thrust spring 34 can provide a certain thrust for the sleeve 16 to ensure a stable connection between the sleeve 16 and the upper hanging member 7.

[0035] like Figure 4-5 As shown, the side wall of the lower hanging member 8 is provided with a supporting groove 35 corresponding to the sliding groove 15. The supporting groove 35 can provide accurate guidance for the lower hanging member 8, so that the upper hanging member 7 and the lower hanging member 8 can correspond more accurately when they are clamped, reducing the skewness or instability of the structure caused by the inability to accurately align, and can also prevent the sleeve 16 from accidentally moving during use, ensuring that the sleeve 16 can still maintain a fixed position when subjected to external force, thereby enhancing the stability and reliability of the entire structure.

[0036] like Figure 8 As shown, the inner side of the sleeve 16 is provided with a guide groove 36 that abuts against the hook-shaped member 14. The guide groove 36 can ensure that the hook-shaped member 14 can smoothly enter the correct position when abutting against the sleeve 16, reducing the time required for multiple adjustments due to the collision of the sleeve 16 with the hook-shaped member 14, thereby improving the overall installation efficiency. The guide groove 36 improves the accuracy and reliability of the clamping, simplifies the clamping process of the hook-shaped member 14, and reduces the difficulty of operation. When the hook-shaped member 14 accurately enters the guide groove 36, a more stable connection can be achieved, reducing loosening or falling off caused by unstable connection, and enhancing the stability and reliability of the entire structure.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
