Description

Technical Field

[0001] The invention belongs to the technical field of power transmission, and in particular relates to an adjustable device and method for hanging cables of overhead power transmission lines. Background Art

[0002] The laying of overhead transmission line cables is usually done by erection. When the transmission line cables are erected, hanging equipment is used. There are many types of existing hanging equipment. Among them, in the existing public document, CN108199325B-Overhead transmission line multi-split conductor hanging equipment, it is disclosed that a hanging body, a tower hanging mechanism and a plurality of hanging devices are provided; the hanging body is provided with a plurality of hanging surfaces connected end to end in sequence and distributed in a ring shape, and a hanging device is provided corresponding to each hanging surface; the hanging device includes a hanging card, and the hanging card is provided with a hanging A notch and a hanging shaft, the hanging notch includes a plurality of snap-in positions arranged side by side in sequence, each snap-in position includes a central arc surface and isolation protrusions located on both sides of the central arc surface; a hanging space is arranged between the hanging notch and the hanging surface, each hanging surface is provided with a hanging hole that is snap-fitted with the hanging shaft, a first magnet is arranged at the end of the hanging shaft, and a second magnet is arranged at the bottom end of the hanging hole; the pole tower hanging mechanism includes a snap-in seat that can be snap-fitted to the pole tower bar steel, the snap-in seat is provided with a connecting shaft, the pole tower bar steel is provided with a connecting hole, and the connecting shaft and the connecting hole are detachably connected.

[0003] Although the above-mentioned existing hanging equipment can be used for hanging transmission line cables, it is necessary to manually open the opening of the hanging part to hang the cable, which is troublesome to operate, and the cable is directly in contact with the bottom of the hanging part, which can easily wear the contact part between the cable and the hanging part;

[0004] In addition, the existing hanging equipment does not have an adjustment function, but only has a limiting function. In actual outdoor use, when the external ambient temperature rises, the cable will expand due to heat and become longer. In windy weather, the loose cable will shake violently under the action of wind and easily fail. When the external ambient temperature is low, the cable will contract when it is cold and become shorter. The taut cable will be subjected to additional mechanical stress at the connection point, bend or bracket, which may cause the cable to break or break or the connection point to loosen, resulting in electrical accidents or fires. To this end, we provide an adjustable cable hanging device and method for overhead transmission line to solve the above problems. Summary of the invention

[0016] The present invention also relates to an adjustment method for an overhead power transmission line cable hanging adjustable device, which is applied to an overhead power transmission line cable hanging adjustable device, and is specifically as follows:

[0017] S1: Monitor the looseness and tightness of the cable:

[0018] During normal use, the No. 1 pressure sensor monitors the pressure value of the cable colliding with the inner wall of the rack in real time when the cable is shaking, so as to determine the looseness or tightness of the cable.

[0019] S2: Preliminary tightening of the cable:

[0020] When the pressure value detected by the No. 1 pressure sensor exceeds the preset range, the No. 1 pressure plate is driven to move horizontally outward to the outermost side through the driving action of the No. 1 transverse driving assembly, and then the No. 1 longitudinal driving assembly is driven to move the slide in the No. 1 longitudinal driving assembly downward, pressing the cable line downward, so that the cable line is tightened;

[0021] S3: Further tighten the cable:

[0022] During the initial tightening of the cable, when the No. 1 pressure plate moves to the bottom and the No. 2 pressure sensor of the No. 1 pressure plate detects that the pressure value has not reached the preset value range, the No. 2 horizontal drive assembly drives the No. 2 pressure plate to move horizontally outward to the outermost side again, and then the No. 2 vertical drive assembly drives the slide in the No. 2 vertical drive assembly to move downward, thereby pressing down the cable, causing the cable to be further tightened.

[0023] The present invention has the following beneficial effects:

[0024] 1. The present invention can automatically tighten the loose cable to a suitable tightness state, and can also relax the taut cable to a suitable tightness state through the setting of the pressure plate mechanism. It has strong adaptability, can adapt to different environments, and has high safety. In addition, a No. 1 pressure plate and a No. 2 pressure plate are provided in the pressure plate mechanism, which can not only perform preliminary tightening or loosening of the cable, but also further tighten or loosen the cable, further improving the adjustment range.

[0025] 2. The present invention adds a protective component at the bottom of the bracket. During normal use, the hemispherical rubber block is rotated upward. Through the action of a group of hemispherical rubber blocks, the friction force of the contact part with the bottom of the cable can be increased, and the shaking amplitude of the cable in the bracket can be reduced. Moreover, through the action of a group of hemispherical rubber blocks, the bottom of the cable can also be prevented from directly contacting the bottom plate of the bracket, thereby reducing the wear of the cable when the cable shakes in the bracket and extending the service life of the cable. In addition, before the tightness of the cable is required, a group of rolling balls are first rotated upward. When adjusting the cable, the rolling action of the rolling balls can assist the cable to move smoothly in the bracket, and after the tightness of the cable is adjusted.

[0026] 3. The present invention, through the arrangement of the gear driving mechanism and the pressing plate mechanism, can automatically open the opening of the hanger and automatically close the opening of the hanger by driving the pressing plate mechanism to move through the gear driving mechanism, so as to facilitate the hanging of the cable.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The slide seat 304 is provided with threaded holes 3041 and through holes 3042 distributed up and down.

[0061] The operation process of this embodiment is as follows: during installation, the bracket 100 is fixed to the support of the transmission tower or the electric pole through the T-shaped ear seat 120 and the matching bolts, and then the two sides of the cable are placed into the brackets 100 of the two electric towers one by one, so that the cable passes through the brackets 100 of the two electric towers;

[0062] During use, the first pressure sensor 101 monitors in real time the pressure value of the cable colliding with the inner wall of the hanger 100 when the cable is shaking, so as to determine the looseness or tightness of the cable;

[0063] When the external ambient temperature rises, the cable expands and lengthens:

[0064] At this time, after the No. 1 pressure sensor 101 detects that the pressure value exceeds the preset range, it immediately transmits a signal to the controller in the control box 150. Through the controller in the control box 150, the No. 2 motor 5011 of the No. 1 horizontal drive component 510 is first started. Through the action of the No. 2 motor 5011 in the No. 1 horizontal drive component 510, the threaded rod 5013 in the No. 1 horizontal drive component 510 is immediately driven to rotate, so that the No. 1 pressure plate 310 is horizontally moved outward to the outermost side. Then, the No. 1 motor 401 of the No. 1 vertical drive component 410 is started. Through the action of the No. 1 motor 401 in the No. 1 vertical drive component 410, the No. 1 screw rod 402 in the No. 1 vertical drive component 410 is immediately driven to rotate, so that the slide 403 in the No. 1 vertical drive component 410 moves downward, and the No. 1 pressure plate 310 moves downward, thereby pressing the cable line downward, causing the cable line to be tightened.

[0065] When the No. 1 pressing plate 310 moves downward to tighten the cable, when the No. 2 pressure sensor 302 of the No. 1 pressing plate 310 detects that the pressure value reaches the preset value range, the signal is immediately transmitted to the controller in the control box 150, and the No. 1 motor 401 of the No. 1 longitudinal driving assembly 410 is stopped by the controller in the control box 150;

[0066] In the process of the No. 1 pressing plate 310 moving downward to tighten the cable, when the No. 1 pressing plate 310 moves downward to the bottom and the No. 2 pressure sensor 302 of the No. 1 pressing plate 310 detects that the pressure value is still lower than the preset value range, at this time, through the controller in the control box 150, the No. 1 motor 401 of the No. 1 longitudinal drive component 410 is stopped first, and then the No. 2 motor 5011 of the No. 2 transverse drive component 520 is started first, and the threaded rod 5013 in the No. 2 transverse drive component 520 is immediately driven to rotate through the action of the No. 2 motor 5011 in the No. 2 transverse drive component 520, so that the No. 2 pressing plate 320 is horizontally moved outward to the outermost side, and then the No. 1 motor 401 of the No. 2 longitudinal drive component 420 is started, and the No. 1 screw rod 402 in the No. 2 longitudinal drive component 420 is immediately driven to rotate through the action of the No. 1 motor 401 in the No. 2 longitudinal drive component 420, so that the slide 403 in the No. 2 longitudinal drive component 420 moves downward, thereby pressing the cable, causing the cable to be further tightened;

[0067] During the further tightening of the cable, when the second pressure sensor 302 of the second pressure plate 320 detects that the pressure value is within the preset value range, the signal is immediately transmitted to the controller in the control box 150, and the first motor 401 of the second longitudinal drive assembly 420 is stopped by the controller in the control box 150;

[0068] When the external ambient temperature decreases, the cable shrinks:

[0069] If the second pressure sensor 302 on the second pressure plate 320 detects a pressure value lower than the preset value range, and the second pressure sensor 302 on the first pressure plate 310 detects a pressure value exceeding the preset value range, the first pressure plate 310 is in a state of pressing the cable line downward, and the second pressure plate 320 is in the initial position;

[0070] At this time, the signal is immediately transmitted to the controller in the control box 150. The controller in the control box 150 first starts the No. 1 motor 401 of the No. 1 longitudinal drive assembly 410. The No. 1 motor 401 in the No. 1 longitudinal drive assembly 410 immediately drives the No. 1 lead screw 402 in the No. 1 longitudinal drive assembly 410 to rotate in the opposite direction, so that the slide 403 in the No. 1 longitudinal drive assembly 410 moves upward, and drives the No. 1 pressing plate 310 to move upward, thereby loosening the cable line, causing the cable line to relax;

[0071] During the upward movement of the No. 1 pressing plate 310, when the No. 2 pressure sensor 302 of the No. 1 pressing plate 310 detects that the pressure value is within the preset value range, the signal is immediately transmitted to the controller in the control box 150, and the No. 1 motor 401 of the No. 1 longitudinal driving assembly 410 is stopped by the controller in the control box 150;

[0072] If it is necessary to move the No. 1 pressing plate 310 to the top, the No. 2 pressure sensor 302 of the No. 1 pressing plate 310 can monitor the pressure value to be within the preset value range, then after the No. 1 pressing plate 310 moves to the top, the No. 2 motor 5011 of the No. 1 horizontal driving assembly 510 is started by the controller in the control box 150, and the No. 2 motor 5011 in the No. 1 horizontal driving assembly 510 immediately drives the threaded rod 5013 in the No. 1 horizontal driving assembly 510 to rotate in the opposite direction, so that the No. 1 pressing plate 310 is horizontally moved inward to the innermost initial position. At this time, the No. 1 pressing plate 310 is close to the hanger 100 to prevent the cable from being decoupled, and the rack 303 of the No. 1 pressing plate 310 is just in mesh with the driving gear 230 on one side of the gear driving mechanism 200;

[0073] When the external ambient temperature decreases, the cable shrinks:

[0074] If the pressure value detected by the second pressure sensor 302 on the first pressure plate 310 and the pressure value detected by the second pressure sensor 302 on the second pressure plate 320 are both beyond the preset value range, the first pressure plate 310 and the second pressure plate 320 are both in the state of pressing down the cable line;

[0075] At this time, the signal is immediately transmitted to the controller in the control box 150. The controller in the control box 150 first starts the No. 1 motor 401 of the No. 2 longitudinal drive assembly 420. The No. 1 motor 401 in the No. 2 longitudinal drive assembly 420 immediately drives the No. 1 screw rod 402 in the No. 2 longitudinal drive assembly 420 to rotate in the opposite direction, so that the slide 403 in the No. 2 longitudinal drive assembly 420 moves up, and drives the No. 2 pressure plate 320 to move up, thereby loosening the cable line, causing the cable line to relax;

[0076] During the upward movement of the second pressing plate 320, when the second pressure sensor 302 of the second pressing plate 320 detects that the pressure value is within the preset value range, the signal is immediately transmitted to the controller in the control box 150, and the first motor 401 of the second longitudinal driving assembly 420 is stopped by the controller in the control box 150;

[0077] If after the No. 2 pressure plate 320 moves to the top, the No. 2 pressure sensor 302 of the No. 1 pressure plate 310 detects that the pressure value is just within the preset value range, then after the No. 2 pressure plate 320 moves to the top, the No. 2 motor 5011 of the No. 2 horizontal drive assembly 520 is started by the controller in the control box 150, and the No. 2 motor 5011 in the No. 2 horizontal drive assembly 520 immediately drives the threaded rod 5013 in the No. 2 horizontal drive assembly 520 to rotate in the opposite direction, so that the No. 1 pressure plate 310 moves horizontally inward to the innermost initial position. At this time, the No. 2 pressure plate 320 is close to the hanger 100 to prevent the cable from being decoupled, and the rack 303 of the No. 2 pressure plate 320 is just in mesh with the driving gear 230 on the other side of the gear drive mechanism 200;

[0078] If after the No. 2 pressure plate 320 moves to the top, the No. 2 pressure sensor 302 of the No. 1 pressure plate 310 detects that the pressure value still exceeds the preset value range, then after the No. 1 pressure plate 310 moves horizontally inward to the innermost initial position, it is necessary to start the No. 1 motor 401 of the No. 1 longitudinal drive assembly 410 through the controller in the control box 150, and the No. 1 motor 401 in the No. 1 longitudinal drive assembly 410 immediately drives the No. 1 lead screw 402 in the No. 1 longitudinal drive assembly 410 to rotate in the opposite direction, so as to move the slide 403 in the No. 1 longitudinal drive assembly 410 upward, and drive the No. 1 pressure plate 310 upward, thereby loosening the cable and causing the cable to relax;

[0079] During the upward movement of the No. 1 pressing plate 310, when the No. 2 pressure sensor 302 of the No. 1 pressing plate 310 detects that the pressure value is within the preset value range, the signal is immediately transmitted to the controller in the control box 150, and the No. 1 motor 401 of the No. 1 longitudinal driving assembly 410 is stopped by the controller in the control box 150;

[0080] If it is necessary to move the No. 1 pressure plate 310 to the top, the No. 2 pressure sensor 302 of the No. 1 pressure plate 310 must monitor the pressure value to be within the preset value range. Then, after the No. 1 pressure plate 310 is moved to the top, it is necessary to start the No. 2 motor 5011 of the No. 1 horizontal drive assembly 510 through the controller in the control box 150 to prompt the No. 1 pressure plate 310 to move horizontally inward to the innermost initial position. At this time, the No. 1 pressure plate 310 is close to the bracket 100 to prevent the cable from being decoupled.

[0081] Example 2

[0082] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 On the basis of Example 1, a protective component 140 is fixed inside the base 130, and the protective component 140 protrudes from the bottom plate of the U-shaped frame 110. The protective component 140 includes a ball rack 141, a micro motor 142, a rolling ball 143 and a hemispherical rubber block 144. Both ends of the ball rack 141 are fixed with an I-shaped shaft, and the I-shaped shaft at one end of the ball rack 141 is connected to the output shaft of the micro motor 142. The micro motor 142 is electrically connected to the controller in the control box 150. A group of evenly distributed circular grooves 1411 are opened on one side of the ball rack 141, and a group of evenly distributed hemispherical rubber blocks 144 are fixed on the other side of the ball rack 141. The inside of each circular groove 1411 is movably connected with a rolling ball 143;

[0083] Two adjacent circular grooves 1411 are connected via a through hole 1412 , and two adjacent rolling balls 143 are connected via a connecting rod 1431 , which crosses the corresponding through hole 1412 .

[0084] Specifically, a first through slot 102 is provided on the bottom plate of the U-shaped frame 110, and first mounting slots 103 are provided on both sides of the first through slot 102;

[0085] A No. 2 through slot 132 is formed inside the base 130 , and No. 2 mounting slots 133 are formed on both sides of the No. 2 through slot 132 . The corresponding No. 1 mounting slot 103 and No. 2 mounting slot 133 are assembled to form an I-shaped slot.

[0086] Furthermore, the I-shaped shaft at one end of the ball rack 141 is movably installed in the I-shaped groove formed by the combination of the No. 1 mounting groove 103 and the No. 2 mounting groove 133 on one side, and the I-shaped shaft at the other end of the ball rack 141 and the micro motor 142 are movably installed as a whole in the I-shaped groove formed by the combination of the No. 1 mounting groove 103 and the No. 2 mounting groove 133 on the other side, and the micro motor 142 is limited by the U-shaped clamp 131.

[0087] The operation process of this embodiment is as follows: in normal use, the micro motor 142 drives the ball rack 141 to rotate as a whole, so that the hemispherical rubber block 144 faces upward. The hemispherical rubber blocks 144 can increase the friction force of the contact part with the bottom of the cable, so that the cable will not shake significantly in the hanger 100. In addition, the hemispherical rubber blocks 144 can also prevent the bottom of the cable from directly contacting the bottom plate of the hanger 100, thereby reducing the wear of the cable when the cable shakes in the hanger 100.

[0088] Before the tightness of the cable is required, the ball rack 141 is driven to rotate as a whole through the action of the micro motor 142, so that a group of rolling balls 143 face upwards. When the cable is adjusted, the rolling action of the rolling balls 143 can assist the cable to move smoothly in the hanger 100. After the tightness of the cable is adjusted, the ball rack 141 is driven to rotate as a whole again through the action of the micro motor 142, so that the hemispherical rubber block 144 faces upwards. The cable is protected again through the action of the group of hemispherical rubber blocks 144.

[0089] Example 3

[0090] See also Figure 1 , Figure 4 , Figure 5 and Figure 7 On the basis of Embodiment 1 and Embodiment 2, a gear driving mechanism 200 is fixed on the outer side of the rack 100, and the gear driving mechanism 200 includes a gear frame 210, a driving motor 220 and a driving gear 230. The driving motor 220 is fixed on the motor seats on both sides of the gear frame 210, and the output shaft of the driving motor 220 is connected to the driving gear 230;

[0091] The pressing plate mechanism 300 includes a first pressing plate 310 and a second pressing plate 320. The first pressing plate 310 and the second pressing plate 320 are respectively placed on both sides of the rack 100.

[0092] The gear driving mechanism 200 drives the first pressing plate 310 and the second pressing plate 320 to move along a direction parallel to the rack 100 .

[0093] Specifically, racks 303 are fixed to the outer side surfaces of the tops of the first pressing plate 310 and the second pressing plate 320 .

[0094] Furthermore, the rack 303 of the first pressure plate 310 meshes with the driving gear 230 on one side of the gear driving mechanism 200 , and the rack 303 of the second pressure plate 320 meshes with the driving gear 230 on the other side of the gear driving mechanism 200 .

[0095] The operation process of this embodiment is as follows: before the cable is hung, a set of driving motors 220 are synchronously started through the touch screen operation on the control box 150, and a set of driving gears 230 are synchronously driven to rotate through the action of the driving motors 220, so that the first pressing plate 310 and the second pressing plate 320 are synchronously moved outward to open the opening of the hanging rack 100;

[0096] After opening the hanging rack 100, place the cable into the hanging rack 100 so that the cable passes through the hanging rack 100;

[0097] After the cable is connected, a set of drive motors 220 are started synchronously through the touch screen operation on the control box 150. Through the action of the drive motors 220, a set of drive gears 230 are synchronously driven to rotate in the opposite direction, causing the first pressure plate 310 and the second pressure plate 320 to move inward synchronously to close the opening of the bracket 100.

[0099] The present invention also relates to an adjustment method for an overhead power transmission line cable hanging adjustable device, which is applied to an overhead power transmission line cable hanging adjustable device, and is specifically as follows:

[0100] S1: Monitor the looseness and tightness of the cable:

[0101] During normal use, the first pressure sensor 101 monitors the pressure value of the cable colliding with the inner wall of the hanger 100 in real time when the cable is shaking, so as to determine the looseness or tightness of the cable;

[0102] S2: Preliminary tightening of the cable:

[0103] When the pressure value detected by the No. 1 pressure sensor 101 exceeds the preset range, the No. 1 pressure plate 310 is driven to move horizontally outward to the outermost side through the driving action of the No. 1 transverse driving assembly 510, and then the No. 1 longitudinal driving assembly 410 is driven to move the slide 403 in the No. 1 longitudinal driving assembly 410 downward, pressing the cable, so that the cable is tightened;

[0104] S3: Further tighten the cable:

[0105] During the initial tightening of the cable, when the No. 1 pressure plate 310 moves down to the bottom and the No. 2 pressure sensor 302 of the No. 1 pressure plate 310 detects that the pressure value has not yet reached the preset value range, the No. 2 horizontal drive component 520 is driven again to cause the No. 2 pressure plate 320 to move horizontally outward to the outermost side, and then the No. 2 vertical drive component 420 is driven to cause the slide 403 in the No. 2 vertical drive component 420 to move downward, thereby pressing down the cable, causing the cable to be further tightened.
