Description

Technical Field

[0001] The invention relates to the technical field of hanging point hardware, and in particular to a tower hanging point hardware and a use method thereof. Background Art

[0002] The hanging point hardware is a key component used to fix the high-voltage transmission cable on the aerial cable chain. Especially in the mountains with different heights, the height of the tower is a fixed value, so the connection points at both ends of the cable connected between two adjacent towers will be located on different horizontal planes, which will lead to the following problems: First, the height difference will cause the loads at the connection points at both ends of the cable to be different. Therefore, the cable at the lower connection point will bear a larger load on the hanging point hardware connected to the tower. However, the existing hanging point hardware is not adjusted according to the load size, which will cause overload problems during the hanging process. Secondly, natural disasters such as strong winds and hail during the hanging process will cause the cable to be disturbed by external forces, which will increase the load borne by the hanging point hardware and cause the cable to have a tendency to deviate on the tower with the hanging point hardware. The existing hanging point hardware itself is fixed. If this part of the deviation trend is not offset and eliminated in time, the hanging point hardware will cause structural damage.

[0003] Therefore, we designed a tower hanging point hardware and its use method. Summary of the invention

[0006] Preferably, the transverse slider slides on the hanging point hardware through a transverse slide groove, a buffer groove is opened in the transverse slide groove, a fixed block is fixed in the buffer groove, the side wall of the transverse slider is provided with a side plate, and the two ends of the first buffer spring are respectively connected to the fixed block and the side plate, and the outer side wall of the first buffer spring is provided with a buffer part for assisting buffering of the first buffer spring.

[0007] Preferably, the buffer portion comprises: A sleeve, the sleeve is coaxially sleeved on the outer side wall of the first buffer spring, the sleeve is provided with an inner cavity, and the inner cavity is provided with a lifting groove connected with the sleeve; The rubber block is provided in multiple configurations, and the rubber block is lifted and lowered through the lifting slot and is buckled on the first buffer spring.

[0008] Preferably, the cross section of the rubber block is an isosceles trapezoid, and the inclined edges on both sides of the rubber block abut against the first buffer spring. The rubber block slides between two adjacent circles of the first buffer spring, and an annular piston slides in the inner cavity.

[0009] Preferably, the insulator string rotates on the longitudinal slider through a rotating ball and a ball groove, and a plurality of first pressing plates and a plurality of second pressing plates are arranged on the longitudinal slider, and two of the first pressing plates and the second pressing plates are arranged, and the two first pressing plates and the two second pressing plates are symmetrically arranged on both sides of the rotating ball.

[0010] Preferably, a plurality of pressing strips are fixed in a circle around the rotating sphere, and there are four pressing strips, and the plurality of pressing strips are respectively connected to the top of the first pressing plate and the second pressing plate, and the first pressing plate and the second pressing plate both telescopically slide on the longitudinal slider through the pressing groove.

[0011] Preferably, the pressing groove where the second pressing plate is located is connected to the inner cavity via a connecting hose, and the connecting hose is fixed on the sleeve via a connecting port.

[0012] Preferably, a spring cavity is opened on the pressing groove where the first pressing plate is located, a limiting plate is arranged in the spring cavity, a resistance rod is provided in the limiting plate for lifting and sliding, one end of the second buffer spring is fixed with a connecting base, and the other end of the second buffer spring is connected to the resistance rod.

[0013] Preferably, the first pressing plate is provided with a chamfer on one side facing the push rod, and the push rod abuts against the chamfer on the first pressing plate.

[0014] A method for using a tower hanging point hardware, the specific operation is as follows: S1: First, when the high-voltage cable suspended between two hanging point fittings encounters different horizontal planes, this will cause the insulator string on the hanging point fitting to swing at different amplitudes on the longitudinal slider. Secondly, when encountering strong winds, the transverse slider will slide horizontally on the hanging point fitting, that is, the swinging direction of the rotating ball on the longitudinal slider will also change; S2: The insulator string presses the first pressing plate with the pressing strip, which will push the first pressing plate down against the push rod and move toward the second buffer spring and press the second buffer spring. At this time, the second buffer spring is compressed, so that the swing of the insulator string in the vertical direction is buffered by the spring; S3: When the insulator string carries the pressing bar to press the second pressing plate down, the hydraulic oil will be squeezed into the inner cavity of the sleeve through the connecting hose, and the rubber block in the sleeve will be pushed to extend between the two adjacent circles of the first buffer spring. When the first buffer spring is subjected to swinging compression, the rubber block will be squeezed to complete the buffering of the first buffer spring.

[0015] The beneficial effects of the present invention are: In the present invention, the longitudinal slider moves in the longitudinal slide groove toward the corresponding pressed second buffer spring. At this time, the downward pressure of the longitudinal slider will be reduced. Compared with the second buffer spring that is not pressed, under the action of the same force, the buffer distance caused by the pressed second buffer spring is shorter than the buffer distance caused by the unpressed second buffer spring. Therefore, the swing amplitude of the longitudinal slider can be effectively reduced, so that the swing amplitude is reduced under the action of external force in the longitudinal direction, and the high-voltage cable can be better stabilized.

[0016] If the wind is stronger, the swing amplitude of the high-voltage cable will be greater, and the sliding distance of the horizontal slider will be longer. At the same time, the distance that the rubber block extends will be longer. Therefore, the extrusion deformation amplitude of the first buffer spring will be smaller. This can also reduce the swing amplitude of the horizontal slider, thereby reducing the swing amplitude under the action of external force in the lateral direction, and better stabilizing the high-voltage cable.

DETAILED DESCRIPTION

[0019] Reference Figure 1-Figure 7 A tower hanging point hardware, comprising a plurality of iron tower bodies 1, and a plurality of hanging point hardware 2 arranged on the iron tower bodies 1, a high voltage cable 3 is set between two adjacent iron tower bodies 1, an insulator string 4 is arranged between the hanging point hardware 2 and the high voltage cable 3, one end of the insulator string 4 is connected to the high voltage cable 3 through a connecting bracket 5, and the other end of the insulator string 4 is connected to a longitudinal slider 7, referring to Figure 2 State, the device is used to connect the high-voltage cable 3 to the hanging point hardware 2 on the iron tower body 1. Since the two adjacent iron tower bodies 1 are at different horizontal planes, the bearing capacity of the high-voltage cable 3 connected to the hanging point hardware 2 on the iron tower body 1 will also be different. Therefore, it is necessary to make corresponding adjustments according to the change of the connection point position of the high-voltage cable 3 on the hanging point hardware 2 to ensure that the high-voltage cable 3 hanging point position will have external support assistance, thereby ensuring that the high position of the end of the high-voltage cable 3 has bearing capacity assistance to avoid accidental falling off.

[0020] The hanging point fitting 2 is provided with a transverse slider 6 for transverse sliding, which is reset and buffered by a first buffer spring 11 , and a longitudinal slider 7 slides longitudinally on the transverse slider 6 through a longitudinal slide groove 14 , which is reset and buffered by a second buffer spring 16 .

[0021] When the high-voltage cable 3 suspended between the two hanging point fittings 2 encounters different horizontal planes, this will cause the insulator string 4 on the hanging point fittings 2 to swing at different amplitudes on the longitudinal slider 7. Secondly, when encountering strong winds, the transverse slider 6 will slide transversely on the hanging point fittings 2, that is, the swinging direction of the rotating ball 20 on the longitudinal slider 7 will also change.

[0022] It should be noted that the lateral sliding block 6 slides horizontally on the hanging point fitting 2 to buffer the lateral force of the airflow on the high-voltage cable 3 in windy weather, so as to avoid the rigid damage caused by the fixed point connection method in the prior art, that is, the fixed connection method in the prior art is replaced by the sliding connection method, which can effectively avoid the damage to the connection point of the high-voltage cable 3 caused by the lateral blowing of the wind; At the same time, the longitudinal slider 7 slides longitudinally on the transverse slider 6 through the longitudinal slide groove 14 to ensure that the iron tower body 1 is located in different terrains, and has a vertical buffering effect at both ends of the high-voltage cable 3, that is, using a sliding connection instead of a fixed connection, which can better protect the connection between the hanging point hardware 2 and the high-voltage cable 3 and avoid the high-voltage cable 3 from falling off.

[0023] Reference Figure 3 and Figure 4 In this state, the insulator string 4 presses the first pressing plate 18 with the pressing strip 21, and the first pressing plate 18 is pressed down against the push rod 29 to move toward the second buffer spring 16 and press the second buffer spring 16. At this time, the second buffer spring 16 is compressed, so that the vertical swing of the insulator string 4 has the buffering of the spring.

[0024] The insulator string 4 rotates on the longitudinal slider 7 by rotating the ball 20 and the ball groove. The longitudinal slider 7 is provided with a plurality of first pressing plates 18 and a plurality of second pressing plates 19. The first pressing plates 18 and the second pressing plates 19 are both provided in twos, and the two first pressing plates 18 and the two second pressing plates 19 are symmetrically provided on both sides of the rotating ball 20. Such a setting ensures that when the insulator string 4 rotates on the longitudinal slider 7 by rotating the ball 20 and the ball groove, the corresponding rotation amplitude can be transmitted to the first pressing plates 18 and the second pressing plates 19 around the rotating ball 20. Since a plurality of pressing strips 21 are fixed circumferentially around the rotating ball 20, and the pressing strips 21 are provided in a circular manner, the first pressing plates 18 and the second pressing plates 19 are provided in a circular manner. There are four pressing strips 21, and multiple pressing strips 21 are respectively connected to the top of the first pressing plate 18 and the second pressing plate 19, so that when the rotating ball 20 rotates in the ball groove, the pressing strips 21 can press the first pressing plate 18 or the second pressing plate 19 in the rotation direction of the rotating ball 20. If it rotates horizontally, it will press the second pressing plates 19 on both sides. If it rotates longitudinally, it will press the first pressing plates 18 on both sides. The first pressing plate 18 and the second pressing plate 19 can both telescope and slide on the longitudinal slider 7 through the pressing groove. The greater the rotation range, the greater the degree of downward pressure on the first pressing plate 18 and the second pressing plate 19 in the pressing groove on the longitudinal slider 7.

[0025] Reference Figure 7In the state, the first pressing plate 18 is provided with a spring cavity 15 on the pressing groove, a limiting plate 28 is arranged in the spring cavity 15, a push rod 29 is provided in the limiting plate 28 for lifting and sliding, a connecting base 30 is fixed to one end of the second buffer spring 16, and the other end of the second buffer spring 16 is connected to the push rod 29. This arrangement can ensure that the first pressing plate 18 is pressed to slide when the rotating ball 20 rotates longitudinally in the ball groove. Since the first pressing plate 18 is provided with a chamfer 27 on the side facing the push rod 29, and the push rod 29 is against the chamfer 27 on the first pressing plate 18, the push rod 29 is pushed down, and then the second buffer spring 16 is pressed. It should be noted that as the rotating ball 20 rotates longitudinally in the ball groove, the corresponding first pressing plate 18 is pressed. The plate 18 will also slide the longitudinal slider 7 on the longitudinal slide groove 14 toward the corresponding direction. The greater the rotation amplitude of the rotating ball 20, the greater the pressing degree of the second buffer spring 16. At this time, the longitudinal slider 7 moves in the longitudinal slide groove 14 toward the corresponding pressed second buffer spring 16. At this time, the downward pressing amplitude of the longitudinal slider 7 will be reduced. Compared with the second buffer spring 16 that is not pressed, under the action of the same force, the buffering distance caused by the pressed second buffer spring 16 is shorter than the buffering distance caused by the unpressed second buffer spring 16. Therefore, the swing amplitude of the longitudinal slider 7 can be effectively reduced, so that the swing amplitude is reduced under the action of external force in the longitudinal direction, and the high-voltage cable 3 can be better stabilized.

[0026] The second pressing plate 19 is connected between the pressing groove and the inner cavity 22 through a connecting hose 17, and the connecting hose 17 is fixed on the sleeve 12 through a connecting port 24. In this way, the deeper the second pressing plate 19 is pressed by the pressing strip 21, the hydraulic oil in the pressing groove of the second pressing plate 19 will be squeezed into the sleeve 12.

[0027] The transverse slider 6 slides on the hanging point hardware 2 through the transverse slide groove 8, a buffer groove 9 is opened in the transverse slide groove 8, a fixed block 10 is fixed in the buffer groove 9, the side wall of the transverse slider 6 is provided with a side plate 13, and the two ends of the first buffer spring 11 are respectively connected to the fixed block 10 and the side plate 13. It should be noted that the transverse slider 6 slides in the transverse slide groove 8 through the buffer groove 9, which is convenient for the airflow to buffer the lateral force of the high-voltage cable 3, and provide a buffer space for the movement of the transverse slider 6.

[0028] The outer side wall of the first buffer spring 11 is sleeved with a buffer part for assisting the buffering of the first buffer spring 11, and the buffer part includes a sleeve 12, and the sleeve 12 is coaxially sleeved on the outer side wall of the first buffer spring 11, and an inner cavity 22 is opened in the sleeve 12, and a lifting groove 25 connected with the inner tube of the sleeve 12 is opened on the inner cavity 22, wherein the inner cavity 22 is filled with hydraulic oil, and an annular piston 23 slides in the inner cavity 22, so that the hydraulic oil entering the inner cavity 22 of the sleeve 12 from the connecting hose 17 will push the annular piston 23 to move, and push the hydraulic oil into multiple lifting grooves 25.

[0029] The buffering part also includes a rubber block 26, which is provided in multiple arrangements. The rubber block 26 is lifted and lowered through the lifting groove 25 and buckled on the first buffer spring 11, that is, the hydraulic oil entering the lifting groove 25 pushes the rubber block 26 to extend out of the lifting groove 25. When the insulator string 4 with the pressing strip 21 presses the second pressing plate 19 to descend, the hydraulic oil will be squeezed into the inner cavity 22 of the sleeve 12 through the connecting hose 17, and the rubber block 26 in the sleeve 12 will be pushed to extend between the two adjacent circles of the first buffer spring 11. When the first buffer spring 11 is subjected to swinging compression, the rubber block 26 will be squeezed to complete the buffering of the first buffer spring 11.

[0030] It should be noted that the cross section of the rubber stopper 26 is an isosceles trapezoid, and the inclined edges on both sides of the rubber stopper 26 are against the first buffer spring 11, and the rubber stopper 26 slides between two adjacent circles of the first buffer spring 11. This arrangement ensures that when encountering strong winds, the horizontal slider 6 will be blown to slide horizontally on the hanging point hardware 2, and the rotating ball 20 will be driven to rotate horizontally in the ball groove and squeeze the second pressing plate 19, and then the rubber stopper 26 extends into the gap between the first buffer springs 11. Therefore, if the first buffer spring 11 is squeezed at this time, it can only shorten the screw thread. However, a rubber stopper 26 is inserted between two adjacent circles of the first buffer spring 11, so the degree of compression of the first buffer spring 11 will be affected. If the wind is stronger, the swing amplitude of the high-voltage cable 3 will be greater, and the sliding distance of the transverse slider 6 will be longer. At the same time, the distance that the rubber stopper 26 is inserted is longer, so the extrusion deformation amplitude of the first buffer spring 11 will be smaller, which can also reduce the swing amplitude of the transverse slider 6, thereby reducing the swing amplitude under the action of external force in the transverse direction, and better stabilizing the high-voltage cable 3.

[0031] A method for using a tower hanging point hardware, the specific operation is as follows: S1: First, when the high-voltage cable 3 suspended between the two hanging point fittings 2 encounters different horizontal planes, this will cause the insulator string 4 on the hanging point fittings 2 to swing on the longitudinal slider 7 at different amplitudes. Secondly, when encountering strong winds, the transverse slider 6 will slide horizontally on the hanging point fittings 2, that is, the swinging direction of the rotating ball 20 on the longitudinal slider 7 will also change; S2: The insulator string 4 presses the first pressing plate 18 with the pressing strip 21, and the first pressing plate 18 is pressed down against the push rod 29 to move toward the second buffer spring 16 and press the second buffer spring 16. At this time, the second buffer spring 16 is compressed, so that the vertical swing of the insulator string 4 is buffered by the spring; S3: When the insulator string 4 carries the pressing strip 21 to press the second pressing plate 19 downward, the hydraulic oil will be squeezed into the inner cavity 22 of the sleeve 12 through the connecting hose 17, and the rubber stopper 26 in the sleeve 12 will be pushed to extend into between the two adjacent circles of the first buffer spring 11. When the first buffer spring 11 is subjected to swinging and squeezing, the rubber stopper 26 will be squeezed, and then the rubber stopper 26 will extend into the gap between the first buffer spring 11. Therefore, if the first buffer spring 11 is squeezed at this time, the pitch can only be shortened. However, the rubber stopper 26 extends between the two adjacent circles of the first buffer spring 11, so the degree of compression of the first buffer spring 11 will be affected. If the wind is stronger, the swing amplitude of the high-voltage cable 3 will be greater, the sliding distance of the horizontal slider 6 will be longer, and the distance the rubber stopper 26 extends will be longer. Therefore, the extrusion deformation amplitude of the first buffer spring 11 will be smaller. In this way, the swing amplitude of the horizontal slider 6 can be reduced, so that the swing amplitude is reduced under the action of external force in the lateral direction, and the high-voltage cable 3 can be better stabilized.
