Description

Technical Field

[0001] The present invention relates to the technical field of power grid maintenance equipment, and particularly to an orbital suspension assembly. Background Art

[0002] With the continuous growth of residential electricity consumption, especially in autumn and winter, the electricity consumption of residents increases. Once a power outage occurs for maintenance, it will inevitably affect the electricity consumption for residents' production and life. Currently, live bypass working is increasingly applied in daily maintenance work. For sudden power failures, maintenance needs to be carried out when the power cable is completely de-energized, and the time to restore power supply is difficult to control, and the losses caused are also inestimable. In this context, the 10kV live bypass working method is widely used. This method can build a temporary power supply system in a short time under the condition of uninterrupted power supply. After all the load currents on the original line are transferred to the bypass drainage line, the original line is disconnected and switches and other equipment are installed. After the maintenance is completed, the bypass system is removed while energized, and the original operation mode of the line is restored. The entire process supplies power to users without interruption and completes complex maintenance operations such as installing switches on the line without the users' knowledge, so as to minimize the losses.

[0003] The existing methods for laying bypass cables mainly adopt the ground laying method. Generally, if the cable and its connection devices are dragged manually on the ground for a long time during use, these components will directly bear the tension, causing insulation damage to the cable and joints. If the operation line encounters road intersections or main channels, the cable will be run over by vehicles when they pass, causing serious damage to the insulation layer on the surface of the cable. Under normal circumstances, a reliable cable protection trough must be used and a special person must be assigned to watch. In addition, due to factors such as complex road traffic, rugged mountain roads, crossing roads, and construction obstacles, normal cable laying cannot be achieved.

[0004] Therefore, currently in complex areas, brackets are usually built to suspend the cable for laying. However, this laying method is complex, requires additional brackets to be erected, has a high operation difficulty, and also has a high cost. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0029] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "above", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below", and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0031] As Figure 1 shown, an embodiment of the present invention provides a track suspension assembly, which is suspended on a support assembly 200 provided on a utility pole 100. The support assembly 200 is installed at a specified position on the utility pole 100, and the track suspension assembly is spaced from the utility pole 100.

[0032] As Figure 1 and 2As shown in the figure, the track suspension assembly includes a suspension plate 1, a first connecting rod 2, a second connecting rod 3 and a track support mechanism 4. The suspension plate 1 is connected to the support assembly 200 through at least two suspension members 5. The first connecting rod 2 is connected to the lower surface of the suspension plate 1. The second connecting rod 3 is horizontally arranged. One end of the second connecting rod 3 is connected to the first connecting rod 2, and the other end is connected to the track support mechanism 4. The track support mechanism 4 includes a support seat 41 fixed on the second connecting rod 3. At least two support rollers 42 are arranged at intervals along the length direction of the track 300 on the support seat 41. The lower surface of the track 300 abuts against the support rollers 42. The track 300 is a rope structure (such as a steel wire rope, a nylon rope, etc.). A pressing member 43 is arranged between at least two of the support rollers 42. The pressing member 43 is connected to an adjusting member 44. The adjusting member 44 can move in the vertical direction to pull the pressing member 43 to move downward. When the pressing member 43 moves downward, the track 300 can be pressed against the support rollers 42. By setting the track suspension assembly, it can be installed on the electric pole 100 to erect the track 300 for conveying cables, reasonably utilize the structure at the power grid maintenance site, without the need to additionally carry a bracket to suspend the cable in the air. Moreover, after the track 300 is erected by this track suspension assembly, a cable supporting assembly (not shown in the figure) slidably arranged on the track 300 can be used to suspend and support the cable, so that the cable will not be dragged on the ground, ensuring that the insulating layer on the outer surface of the cable is not damaged. In addition, the laying difficulty of the cable can be reduced because the cable supporting assembly sliding on the track 300 can transport the cable to the required position under the action of an external force, without the operator hanging the cable at a high altitude; by setting two suspension members 5, the stability of the whole device during suspension can be enhanced, preventing the track suspension assembly from swinging in the air; by setting the pressing member 43 and the adjusting member 44, it is convenient to press the rope-structured track 300, so that the track 300 is always in a taut state, facilitating the cable supporting assembly to slide smoothly on the track 300.

[0033] Further, at least two of the suspension members 5 are horizontally arranged at intervals on the suspension plate 1, and at least two of the suspension members 5 are arranged along a direction perpendicular to the length direction of the track 300. By arranging the two suspension members 5 along a direction perpendicular to the length direction of the track 300, the stability of the whole track suspension assembly after installation can be enhanced.

[0034] In other embodiments, three suspension members 5 may also be provided on the suspension plate 1. The individual suspension members 5 are arranged in an isosceles triangle on the suspension plate 1, and the center of the isosceles triangle is on the same vertical line as the overall center of gravity of the track support mechanism 4. That is to say, when viewed vertically downward, the projection of the center of the isosceles triangle coincides with the overall center of gravity of the track support mechanism 4. The suspension members 5 arranged in an isosceles triangle, combined with their special installation positions, can greatly improve the stability of the track support mechanism 4, prevent it from swinging, and further prevent the track 300 provided on the track support mechanism 4 from swinging, ensuring the stability of the track 300 and facilitating the cable conveyance. The number of the suspension members 5 is not limited to two or three, and may also be four or more.

[0035] In one embodiment, as Figure 3 shown (and referring to Figure 1 and Figure 2 ), the pressing member 43 includes a pressing plate 431. The upper surface of the pressing plate 431 is an arc surface. The lower surface of the pressing plate 431 abuts against the upper surface of the track 300. The adjusting member 44 includes an adjusting rod 441. One end of the adjusting rod 441 is connected to one end in the width direction of the pressing plate 431, and the other end passes through the first through hole 411 in the support seat 41 and is located below the support seat 41. External threads are provided on the adjusting rod 441, and an adjusting nut 46 is screwed on the adjusting rod 441. By providing the pressing plate 431, with the cooperation of the adjusting rod 441 and the adjusting nut 46, the pressing plate 431 will press the track 300. The upper surface of the pressing plate 431 is an arc, which can reduce the obstruction when the cable supporting assembly moves to this position, ensuring that the cable supporting assembly can smoothly cross the position pressed by this pressing plate 431. Moreover, this pressing plate 431 is arranged in an open structure, so it can be installed after the track 300 is laid, effectively reducing the installation difficulty.

[0036] Furthermore, a pre-tightening spring 45 is sleeved outside the adjusting rod 441. The pre-tightening spring 45 is located in the first through hole 411. One end of the pre-tightening spring 45 abuts against the pressing plate 431, and the other end abuts against the adjusting nut 46. By providing the pre-tightening spring 45, loosening of the pressing member 43 can be completely prevented. Even if the adjusting nut 46 loosens, under the elastic force of the pre-tightening spring 45, the adjusting rod 441 always has a downward movement tendency, that is, the pressing plate 431 always has a downward movement tendency to press the track 300.

[0037] Preferably, the pressing plate 431 includes an arc-shaped pressing body 4311. One end of the pressing body 4311 in the width direction extends vertically with a connecting plate 4312. The adjusting rod 441 is connected to the connecting plate 4312. A through groove 4313 is formed through the connecting plate 4312 along the length direction of the track 300. The cross-section of the through groove 4313 is T-shaped. The through groove 4313 has a first notch 43131 on the lower surface of the connecting plate 4312 and second notches at both ends of the connecting plate 4312 in the length direction. A clamping portion 442 is provided at the end of the adjusting rod 441. The clamping portion 442 is inserted into the through groove 4313 from the second notch. The adjusting rod 441 passes through the first notch 43131. The size of the connecting plate 4312 is larger than the width of the first notch 43131. By providing the through groove 4313 with a T-shaped structure and cooperating with the adjusting rod 441 and the clamping portion 442, quick installation and disassembly of the pressing plate 431 can be achieved, reducing the difficulty of disassembly and assembly. Even if one person installs it on the electric pole 100, it can be quickly installed.

[0038] In other embodiments, such as Figure 1 and 2 shown, the pressing member 43 includes a pressing tube 432. The pressing tube 432 is sleeved on the track 300. One end of the adjusting rod 441 of the adjusting member 44 is connected to the lower end of the pressing tube 432, and the other end passes through the first through hole 411 on the support seat 41 and is located below the support seat 41. Preferably, the pressing tube 432 and the adjusting rod 441 are welded together. By setting the pressing mechanism as the pressing tube 432, the integral structure composed of the pressing tube 432 and the adjusting rod 441 can be first inserted through the track 300 before the track 300 is laid on the support rollers 42 of the track support mechanism 4, and then the track 300 is laid.

[0039] Preferably, a non-slip rubber layer is provided on the side surface of the pressing member 43 that abuts against the track 300. By providing the non-slip rubber layer, the track 300 can be prevented from being worn out by the rigid pressing member 43, and the service life of the track 300 can be extended. The non-slip rubber layer can be fixed on the pressing member 43 by means of bonding or hot melt connection.

[0040] In a specific embodiment of the present invention, the cross-section of the track 300 is circular, and the side surface of the pressing member 43 that abuts against the track 300 is arc-shaped. This structure can further reduce the wear of the pressing member 43 on the track 300.

[0041] In one embodiment, such as Figure 4As shown in the figure, the first connecting rod 2 has a structure with adjustable length. Specifically, the first connecting rod 2 includes a first sleeve 21 and a second sleeve 22. The upper end of the first sleeve 21 is connected to the lower surface of the hanging plate 1. The lower end of the first sleeve 21 is inserted into the second sleeve 22. The lower end of the second sleeve 22 is connected to the second connecting rod 3. A fixing hole 211 is radially penetrated through the first sleeve 21 along its radial direction. An adjusting hole 221 is radially penetrated through the second sleeve 22 along its radial direction. The adjusting hole 221 is an elongated hole, and the length of the adjusting hole 221 extends in the vertical direction. An adjusting bolt (not shown in the figure) passes through the fixing hole 211 and the adjusting hole 221 and is screwed with a nut to fix the first sleeve 21 and the second sleeve 22. The support assembly 200 provided on the electric pole 100 is generally arranged at a height of more than ten meters. When installing the support assembly 200, it may not be possible to install it at the required position. Therefore, adjustment needs to be carried out at a high altitude. However, it is difficult to operate to adjust the height of the entire support assembly 200, and there are potential safety hazards. Therefore, the first connecting rod 2 is set to an adjustable mode, which can reduce the adjustment difficulty.

[0042] In addition, the telescopic adjustment difficulty of the first connecting rod 2 can also be reduced. The first sleeve 21 and the second sleeve 22 can also be screwed together. Specifically, the upper end of the first sleeve 21 is connected to the lower surface of the hanging plate 1. An external thread is provided on the outside of the first sleeve 21, and an internal thread is provided on the inner wall of the second sleeve 22. The first sleeve 21 is screwed into the second sleeve 22. A limiting plate is provided at the lower end of the second sleeve 22. A second through hole is provided on the second connecting rod 3. The lower end of the second sleeve 22 passes through the second through hole and is fixedly connected to the limiting plate. The setting of the second through hole prevents the second connecting rod 3 from rotating together when the second sleeve 22 rotates.

[0043] In an embodiment, two hanging plates 6 are spaced apart on the upper surface of the hanging plate 1. Hanging holes are provided on the hanging plates 6. The hanging member 5 includes a first lock 51 and a second lock 52. The first lock 51 includes a U-shaped first body. Both ends of the first body are fixed to the support assembly 200 through a first locking bolt and a first locking nut. The second lock 52 includes a U-shaped second body. The second body passes through the first body, and both ends of the second body are fixed to the hanging plate 6 through a second locking bolt and a second locking nut.

[0044] Preferably, the centers of the hanging holes of the two hanging plates 6 are concentric, and the central axes of the two hanging plates 6 are horizontally arranged.

[0045] The number and arrangement positions of the hanging plates 6 on the hanging plate 1 are the same as the number and arrangement positions of the hanging members 5.
