Description

Technical Field

[0001] The present invention belongs to the technical field of power grid operation and maintenance, and in particular relates to a supporting device for an insulating operating rod of a high-voltage transmission line. Background Art

[0002] Insulated operating rods are commonly used tools in power grid operation and maintenance. When workers use insulated operating rods for live operations, they need to keep lifting or even holding them horizontally for a long time. However, due to the heavy weight of the insulated operating rods, it is physically demanding to lift or hold them horizontally for a long time, which is not conducive to the accuracy of live operations.

[0003] In the prior art, in order to achieve labor-saving operation of the insulating operating rod, the rod body of the insulating operating rod is usually placed directly on the pole tower angle iron, and the pole tower angle iron is used as a fulcrum to save physical effort when operating the insulating operating rod. However, the existing insulating operating rods are mostly made of synthetic materials. When the pole tower angle iron is used to provide support for the insulating operating rod, the pole tower angle iron will generate greater friction on the insulating operating rod, which can easily cause damage to the surface of the insulating operating rod, thereby affecting the insulation performance of the insulating operating rod, and thus posing a great threat to the safety of the workers. Summary of the Invention

[0010] One end of the pressure-bearing component extends to the inside of the slot, and the other end extends to the inside of the chamber. When the pressure-bearing component is under pressure, it can drive the limiting component to move upward compared to the support to release the limiting state of the support, so that the support can rotate compared to the hinged component.

[0014] One end of the support rod is fixedly connected to the support plate, and the other end is fixedly connected to the sphere. A spherical groove adapted to the sphere is provided at the bottom of the support, wherein three-quarters of the sphere is movably embedded in the spherical groove.

[0015] As a further improvement of the present invention: the limiting assembly includes a limiting rod,

[0016] The limiting rods are provided in a plurality of groups, and the limiting rods are distributed in an annular manner at intervals outside the sphere. One end of the limiting rods abuts against the support plate, and the other end passes through the support and extends to the inside of the chamber. The limiting rods are movably matched with the support, and a second rack is fixedly provided on the side wall of the rod body of the limiting rod located inside the chamber.

[0017] The pressure component includes an arc-shaped pressure plate and a pressure rod.

[0018] The arc-shaped pressure plate is movably arranged inside the slot, one end of the pressure rod is fixedly connected to the bottom of the arc-shaped pressure plate, and the other end passes through the support and extends to the inside of the chamber, the pressure rod is arranged at the center position of several limit rods, the pressure rod is movably cooperated with the support, and several first racks are provided on the side wall of the rod body of the pressure rod located inside the chamber, and a group of transmission gears are meshed on one side of each group of the first racks, and each group of the transmission gears is meshed with the second racks on a group of the limit rods on the side away from the corresponding first racks.

[0019] As a further improvement of the present invention: one end of the pressure rod located inside the chamber is further connected to the inner wall of the chamber through an elastic member, and the elastic member is used to provide elastic support for the pressure rod.

[0020] As a further improvement of the present invention: a bracket plate is fixedly provided on the inner wall of the chamber, and the transmission gear is rotatably mounted on one side of the bracket plate.

[0021] As a further improvement of the present invention: the elastic member is a spring or a metal spring.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] In an embodiment of the present invention, when live work is required, the clamping assembly can be clamped on the pole tower angle iron, thereby limiting the support plate and the support to one side of the pole tower angle iron. At this time, the limit assembly limits the support to an upright state, and then the staff inserts the insulating operating rod body into the groove on the upper part of the support. When the insulating operating rod body is inserted into the groove, the pressure-bearing assembly can be driven to be compressed, thereby causing the limit assembly to move up compared to the support to release the limited state of the support. At this time, the support can be flexibly rotated compared to the hinge assembly, thereby providing rotational support for the insulating operating rod, so that the staff can operate the insulating operating rod flexibly and labor-savingly, thereby improving the convenience of live work. Compared with the existing technology, when using the insulating operating rod for live work, there is no need to use the pole tower angle iron to provide support for the insulating operating rod, which avoids wear of the insulating operating rod and extends the service life of the insulating operating rod.

DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0030] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0031] See also Figure 1 、 Figure 2 as well as Figure 3 The present embodiment provides a support device for an insulating operating rod of a high-voltage transmission line, comprising a support plate 10, a clamping assembly 20, a support 30, a pressure-bearing assembly 40, a limiting assembly 50, and a hinge assembly 60. The clamping assembly 20 is provided at one end of the support plate 10 for clamping the support plate 10 and the support 30 on the angle iron of the tower. The support 30 is mounted on the upper part of the support plate 10 through the hinge assembly 60. A notch 301 is provided on the upper end of the support 30 for inserting the insulating operating rod. A chamber 302 is opened inside 30, and the positioning component 50 is installed on the bottom wall of the support 30, and is used to limit the support 30 so that the support 30 remains in an upright state. One end of the pressure component 40 extends to the inside of the slot 301, and the other end extends to the inside of the chamber 302. When the pressure component 40 is pressurized, it can drive the limiting component 50 to move upward compared to the support 30 to release the limiting state of the support 30, so that the support 30 can rotate compared to the hinge component 60.

[0032] When live work is required, the clamping assembly 20 can be clamped on the pole tower angle iron, thereby confining the support plate 10 and the support 30 to one side of the pole tower angle iron. At this time, the limit assembly 50 limits the support 30 to an upright state, and then the staff inserts the insulating operating rod body into the groove 301 on the upper part of the support 30. When the insulating operating rod body is inserted into the groove 301, the pressure assembly 40 can be driven to be compressed, thereby causing the limit assembly 50 to move up compared to the support 30 to release the confined state of the support 30. At this time, the support 30 can be flexibly rotated compared to the hinge assembly 60, thereby providing rotational support for the insulating operating rod, so that the staff can operate the insulating operating rod flexibly and labor-savingly, thereby improving the convenience of live work.

[0033] See also Figure 1 、 Figure 2 as well as Figure 3 In one embodiment, the clamping assembly 20 includes a U-shaped clamp 201 and a locking bolt 202. The U-shaped clamp 201 is fixedly arranged at one end of the support plate 10, and the locking bolt 202 is installed on the side wall of the U-shaped clamp 201 and is threadedly engaged with the U-shaped clamp 201.

[0034] When live work is required, the U-shaped clamp 201 can be clamped on the outside of the pole tower angle iron, and then the locking bolt 202 can be screwed so that the locking bolt 202 is screwed into the inside of the U-shaped clamp 201, thereby supporting it against the side wall of the pole tower angle iron, thereby realizing the limitation of the support plate 10 and the support 30.

[0035] See also Figure 2 In one embodiment, the hinge assembly 60 includes a sphere 601 and a support rod 602, one end of the support rod 602 is fixedly connected to the support plate 10, and the other end is fixedly connected to the sphere 601, and a spherical groove (not shown in the figure) adapted for the sphere 601 is provided at the bottom of the support 30, wherein three-quarters of the sphere 601 is movably embedded in the spherical groove.

[0036] After the locking bolt 202 is supported on the side wall of the tower angle iron to complete the limitation of the support plate 10 and the support 30, the support 30 remains in an upright state under the limitation of the limit component 50. At this time, the support 30 cannot rotate relative to the sphere 601. Then the staff embeds the rod body of the insulating operating rod into the groove 301 on the upper part of the support 30, so that the pressure component 40 is pressurized to drive the limit component 50 to move up relative to the support 30, thereby releasing the limitation state of the support 30. At this time, when the staff operates the insulating operating rod to perform live work, the support 30 can be adaptively rotated relative to the sphere 601 under the influence of the movement of the insulating operating rod. The support 30 provides flexible support for the insulating operating rod, thereby reducing the operating force of the insulating operating rod.

[0037] See also Figure 1 、 Figure 2 as well as Figure 4In one embodiment, the limiting assembly 50 includes a limiting rod 501, and the limiting rod 501 is provided with several groups. Several of the limiting rods 501 are distributed in an annular manner on the outside of the sphere 601. One end of several of the limiting rods 501 abuts against the support plate 10, and the other end passes through the support 30 and extends into the interior of the chamber 302. Several of the limiting rods 501 are movably matched with the support 30. The limiting rod 501 is located on the side wall of the rod body inside the chamber 302 and is fixed with a second rack 502. The pressure assembly 40 includes an arc-shaped pressure plate 401 and a pressure rod 402. The arc-shaped pressure plate 401 is movably arranged in the slot. Inside 301, one end of the pressure rod 402 is fixedly connected to the bottom of the arc-shaped pressure plate 402, and the other end passes through the support 30 and extends to the inside of the chamber 302. The pressure rod 402 is arranged at the center position of several of the limit rods 501, and the pressure rod 402 is movably matched with the support 30. The pressure rod 402 is located on the side wall of the rod body inside the chamber 302. A group of first racks 403 are meshed with a group of transmission gears 405 on one side of each group of the first racks 403, and each group of the transmission gears 405 is meshed with the second racks 502 on a group of the limit rods 501 on the side away from the corresponding first racks 403.

[0038] After the locking bolts 202 are supported on the side wall of the angle iron of the tower and the support plate 10 and the support 30 are limited, one end of the plurality of limiting rods 501 abuts against one side of the support plate 10, thereby limiting the support 30, so that the support 30 remains in an upright state, so that the staff can stably embed the insulating operating rod body into the groove 301 on the upper part of the support 30; when the insulating operating rod body is embedded in the groove 301, the insulating operating rod can drive the arc pressure plate 401 along the groove 301. 01 moves downward inside, thereby driving the pressure rod 402 to move into the chamber 302. When the pressure rod 402 moves, it drives several first racks 403 to move synchronously. The meshing transmission effect of several first racks 403, several transmission gears 405 and several second racks 502 can drive several limit rods 501 to move synchronously into the chamber 302, that is, several limit rods 501 move up compared to the support 30, so that one end of several limit rods 501 is separated from the support plate 10, thereby releasing the limit on the support 30. At this time, when the staff operates the insulating operating rod to perform live work, the insulating operating rod can drive the support 30 so that the support 30 rotates adaptively compared to the ball 601. The support 30 provides flexible support for the insulating operating rod, making the operation of the insulating operating rod labor-saving and convenient. When the insulating operating rod is moved out of the slot 301, the support 30 may be in a tilted state, thereby causing the pressure rod 402 and several limit rods 501 to be in a tilted state, and the elastic member 405 pushes The dynamic pressure rod 402 causes several limit rods 501 to move downward compared to the support 30, and a group of inclined limit rods 501 will be in advance in contact with the support plate 10. This group of limit rods 501 can push the support 30 so that the support 30 deflects in the opposite direction of the tilt until the support 30 deflects to an upright state. Several limit rods 501 are in contact with the support plate 10 synchronously, thereby correcting the posture of the support 30 so that the subsequent insulating operating rod can be easily embedded in the slot 301 again.

[0039] See also Figure 4 In one embodiment, one end of the pressure rod 402 located inside the chamber 302 is also connected to the inner wall of the chamber 302 through an elastic member 404 , and the elastic member 404 is used to provide elastic support for the pressure rod 402 .

[0040] When the insulating operating rod is embedded in the slot 301 and drives the arc pressure plate 401 and the pressure rod 402 to move, the elastic member 404 is compressed; when the live operation is completed, the staff moves the insulating operating rod body out of the slot 301. At this time, the elastic member 404 pushes the pressure rod 402 so that the pressure rod 402 moves toward the inside of the slot 301, thereby driving the arc pressure plate 401 to move upward along the inside of the slot 301. During the movement of the pressure rod 402 toward the inside of the slot 301, the reverse meshing transmission action of the first racks 403, the transmission gears 405 and the second racks 502 can drive the limiting rods 501 to move downward compared to the support 30. When the limiting rods 501 move downward, they re-contact the side of the support plate 10, thereby re-limiting the support 30, so that the support 30 remains in an upright state again.

[0041] See also Figure 4 In one embodiment, a support plate 303 is fixedly installed on the inner wall of the chamber 302 , and the transmission gear 405 is rotatably installed on one side of the support plate 303 .

[0042] In one embodiment, the elastic member 405 may be a spring or a metal spring, which is not limited here.

[0043] In an embodiment of the present invention, when live work is required, the clamping assembly 20 can be clamped on the pole tower angle iron, thereby limiting the support plate 10 and the support 30 to one side of the pole tower angle iron. At this time, the limit assembly 50 limits the support 30 to an upright state, and then the staff inserts the insulating operating rod body into the groove 301 on the upper part of the support 30. When the insulating operating rod body is inserted into the groove 301, the pressure-bearing assembly 40 can be driven to be compressed, thereby causing the limit assembly 50 to move up compared to the support 30 to release the limited state of the support 30. At this time, the support 30 can be flexibly rotated compared to the hinge assembly 60, thereby providing rotational support for the insulating operating rod, so that the staff can operate the insulating operating rod flexibly and labor-savingly, thereby improving the convenience of live work. Compared with the prior art, when using the insulating operating rod for live work, there is no need to use the pole tower angle iron to provide support for the insulating operating rod, which avoids wear of the insulating operating rod and extends the service life of the insulating operating rod.

[0044] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
