Description

Technical Field

[0001] The invention belongs to the technical field of high-voltage line maintenance, and in particular relates to a mounting frame for X-ray flaw detection of a four-split conductor tension clamp. Background Art

[0002] Split conductor refers to a conductor installation method adopted by ultra-high voltage transmission lines to suppress corona discharge and reduce line reactance, that is, each phase conductor is composed of several branch conductors with smaller diameters, and each branch conductor is arranged at a certain distance and in a symmetrical polygon, and arranged at the vertices of a regular polygon. Split conductors distribute the charge of each phase on each branch conductor, which is equivalent to increasing the radius of the phase conductor and reducing the charge density on the conductor surface, thereby reducing the electric field intensity on the conductor surface and suppressing corona discharge; in addition, split conductors can reduce the inductance of the transmission line, increase the capacitance, reduce the wave impedance to AC power, and improve the transmission capacity of the line.

[0003] The tension clamp can firmly fix each sub-conductor of the split conductor on the tension insulator string of the non-linear tower, so that the conductor maintains a stable tension and position between the towers, and prevents the conductor from being displaced or falling off due to various external forces. As a key hardware connecting the split conductor and the insulator string and other components, the tension clamp is subjected to various mechanical forces such as the tension of the conductor, wind load, ice load, etc. Long-term mechanical stress may cause the crimping part of the conductor inside the tension clamp to loosen, fatigue crack, and even cause serious problems such as steel core fracture. If these internal defects are not discovered in time, they may cause line failures, such as conductor shedding and short circuit, which pose a huge threat to the safe and stable operation of the power system.

[0004] At present, most of the detection of tension clamps uses drone X-ray flaw detection technology, because X-ray flaw detection technology can penetrate the metal shell of the tension clamp and image its internal structure. It can clearly show the crimping condition of the wire inside the tension clamp, the state of the steel core, whether there are internal defects such as voids and slag inclusions. Application publication number CN115494090A discloses "a drone mounting device for X-ray flaw detection of power transmission lines and its mounting platform", in which the drone mounting platform includes a mounting part, the mounting part includes an X-ray machine, a protective mechanism, a bracket and an imaging acquisition mechanism, both sides of the imaging acquisition mechanism are connected to a wire clamping plate, and the side of the wire clamping plate close to the X-ray machine is provided with a guide hanging groove for locating the transmission line; both sides of the top of the imaging acquisition mechanism are provided with front suspension ropes, the protective mechanism is connected to an electric winch for winding the rear suspension rope, and the tops of the front suspension rope and the rear suspension rope are connected to hooks for mounting drones. In the above technical solution, the mounting platform is lifted above the split conductor by a drone, and is hung on the conductor through the guide hanging groove of the wire clamping plate. During operation, the drone must first be vertically lowered to the position where the hanging groove is aligned with the conductor, and then the drone is operated to make the hanging groove bayonet clamp on the conductor. The operation is difficult and it is neither convenient to hang on the conductor nor to detach from the conductor. Summary of the invention

[0021] 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. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0022] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0023] Embodiment 1 of the mounting frame for X-ray flaw detection of the four-split conductor tension clamp provided by the present invention: like Figure 1 As shown, the mounting frame for X-ray flaw detection of the four-split conductor tension clamp includes a frame 1, an imaging plate 2 mounted on the frame 1, four moving cylinders 5 mounted on the frame 1 and distributed in a rectangular shape, a rotary drive mechanism connected to the four moving cylinders 5, and a lifting drive mechanism arranged between the imaging plate 2 and the frame 1.

[0024] The frame 1 is made of carbon fiber tubes, which is light and strong. The frame 1 includes a top rectangular frame 9 and four vertical poles 10 respectively connected to the four corners of the top rectangular frame 9. The four vertical poles 10 are respectively arranged on the periphery of the four split conductors.

[0025] The top rectangular frame 9 includes two transverse tubes and three longitudinal tubes, each of which is provided with two first supports 26 and two second supports 27. Among the four moving cylinders 5, two coaxially arranged moving cylinders 5 are respectively rotatably assembled on the corresponding first supports 26 through the axles 25. The two second supports 27 are located between the two first supports 26. The rotary drive mechanism includes four independent wireless remote control motors 24, each of which is fixed on the corresponding second support 27, and the output shaft of the wireless remote control motor 24 is connected to the axle 25 of the corresponding moving cylinder 5. The four wireless remote control motors 24 are remotely controlled by ground personnel and act synchronously to realize the synchronous rotation of the four moving cylinders 5. The moving cylinder 5 is provided with a plurality of laps of limiting ring grooves 28 in the axial direction thereof, and the limiting ring grooves 28 are used to be stuck on the corresponding wires so that the four moving cylinders 5 can be guided and moved on the two wires located above the four split wires.

[0026] A hanging part 3 and a power source 4 are installed between the two longitudinal tubes close to the imaging plate 2. The power source 4 is electrically connected to each wireless remote-controlled motor 24. The hanging part 3 is used to hook with the mechanical arm of the drone.

[0027] The imaging plate 2 is arranged on the side of the frame 1 and outside the four-branch wire, and the imaging plate 2 will not interfere with the frame 1 when it is raised or lowered. Figure 2 and Figure 3 As shown, the lifting drive mechanism includes a lifting motor 6, a driving gear 7 connected to the output shaft of the lifting motor 6, and a vertical rack 11 connected to the imaging board 2. The driving gear 7 is meshed with the vertical rack 11, and the output shaft of the lifting motor 6 is connected to an electromagnetic brake; a support frame 12 is provided outside the imaging board 2, and the vertical rack 11 is connected to the support frame 12. Two vertical poles 10 close to the imaging board 2 are provided with T-shaped guide grooves 14 extending in the up-down direction, and the support frame 12 is connected with a T-shaped guide rod 13 that cooperates with the T-shaped guide groove 14. The use of the T-shaped guide rod 13 and the T-shaped guide groove 14 can prevent the imaging board 2 from detaching from the frame 1. A support plate 8 is connected to the vertical pole 10 close to the vertical rack 11, and the lifting motor 6 is fixed to the support plate 8.

[0028] The working principle of the mounting frame for X-ray flaw detection of four-split conductor tension clamp of the present invention is as follows: first, the mechanical arm of the drone is used to hook the hooking part 3 on the frame body 1, and the entire mounting frame is lifted to the position of the four-split conductor by the drone, so that the four moving cylinders 5 are respectively in contact with the two wires at the top, and the ground personnel remotely control the mounting frame to move to the tension clamp detection position by themselves; during the movement, when the limiting ring groove 28 is stuck on the wire, the entire mounting frame will gradually correct automatically under the limiting action of the limiting ring groove 28 when continuing to move, so that the mounting frame does not deflect. That is, when the drone lowers the mounting frame, the moving cylinder 4 only needs to contact the wire, and there is no need to lower the limiting ring groove 28 directly against the wire, which makes the operation simpler. The drone mounted with an X-ray flaw detector flies to one side of the four-split conductor to detect the tension clamp, and another drone mounted with a camera flies to the imaging board 2, facing the imaging board 2 to shoot, and the remote control lifting motor 6 makes the imaging board 2 move up and down, and cooperates with the camera hovering position to complete the full-range shooting of the four wires.

[0029] Embodiment 2 of a mounting frame for X-ray flaw detection of a four-split conductor tension clamp provided by the present invention: The difference between this embodiment and the first embodiment is only the structure of the rotary drive mechanism and the installation method of the moving cylinder 5. In the first embodiment, the rotary drive mechanism uses four wireless remote control motors 24 to drive the four moving cylinders 5 to rotate respectively, and the moving cylinders 5 and the frame 1 are in a rotationally assembled relationship.

[0030] In this embodiment, the rotary drive mechanism includes a rotary motor 23, a first transmission shaft 15, a second transmission shaft 16, a bevel gear assembly and a synchronous transmission structure. The two ends of the first transmission shaft 15 are respectively connected to the wheel shafts 25 of two coaxially arranged moving cylinders 5, the two ends of the second transmission shaft 16 are transmission-connected to the wheel shafts 25 of the other two coaxially arranged moving cylinders 5, and the first transmission shaft 15 and the second transmission shaft 16 are arranged in parallel and spaced apart. A support is provided on the top rectangular frame 9, which is arranged close to the first transmission shaft 15, and the rotary motor 23 is fixed on the support and electrically connected to the power supply 4. The synchronous transmission structure is a belt transmission structure, which is arranged between the first transmission shaft 15 and the second transmission shaft 16. The synchronous transmission structure includes a main pulley 18, a secondary pulley 19 and a transmission belt 20, the main pulley 18 and the secondary pulley 19 are coaxially fixed on the first transmission shaft 15 and the second transmission shaft 16, respectively, and the transmission belt 20 is connected between the main pulley 18 and the secondary pulley 19. The bevel gear assembly includes a main bevel gear 21 fixed to the output shaft of the rotary motor 23 and a secondary bevel gear 22 meshing with the main bevel gear 21, and the secondary bevel gear 22 is coaxially fixed to the first transmission shaft 15. Of course, when the installation position of the rotary motor 23 is close to the second transmission shaft 16, the secondary bevel gear 22 is coaxially fixed to the second transmission shaft 16.

[0031] Each moving cylinder 5 has no assembly relationship with the top rectangular frame 9, but is connected to the first transmission shaft 15 and the second transmission shaft 16, and realizes its own rotation by the rotation of the first transmission shaft 15 and the second transmission shaft 16. In this embodiment, four moving cylinders 5 are driven to rotate simultaneously by a rotary motor 23, which is more cost-effective.

[0032] Embodiment 3 of a mounting frame for X-ray flaw detection of a four-split conductor tension clamp provided by the present invention: The difference between this embodiment and the first embodiment is that the structure of the rotary drive mechanism and the installation method of the moving cylinder 5 are different. In this embodiment, the structure of the rotary drive mechanism is the same as that of the rotary drive mechanism in the above-mentioned second embodiment, and will not be described in detail here, while the installation method of the moving cylinder 5 is different from that in the above-mentioned second embodiment.

[0033] In this embodiment, the distance between the two coaxially arranged moving cylinders 5 is adjustable, specifically: the two ends of the first transmission shaft 15 and the second transmission shaft 16 are respectively plugged with the corresponding side axle 25, and the plugging depth of the first transmission shaft 15 and the axle 25, and the second transmission shaft 16 and the corresponding axle 25 are adjustable. The first transmission shaft 15 is provided with a plurality of first plug holes arranged at intervals at the plugging position with the corresponding axle 25, and the second transmission shaft 16 is provided with a plurality of second plug holes at the plugging position with the corresponding axle 25, and each axle 25 is provided with a second plug hole, and a plug pin 17 is detachably plugged in the second plug hole and the corresponding first plug hole, and the plug pin 17 is used to make the two ends of the first transmission shaft 15 and the axle 25 stop rotating, and make the two ends of the second transmission shaft 16 and the axle 25 stop rotating.

[0034] In this embodiment, the distance between the two coaxially arranged moving cylinders 5 is adjusted by adjusting the insertion depth between the wheel axle 25 and the first transmission shaft 15 and the second transmission shaft 16, so that the entire mounting frame can be used for four-split conductors with different spacings.

[0035] Of course, in other embodiments, based on the above-mentioned embodiment 3, the frame 1 can also be made into a telescopic frame to realize the adjustment of the distance between the two coaxially arranged movable cylinders 5. At this time, the top rectangular frame 9 is a telescopic frame, and the first transmission shaft 15 and the second transmission shaft 16 are both telescopic shafts.

[0036] In the description of the present specification, “plurality” means at least two, for example, two, three or more, etc., unless otherwise clearly and specifically defined.

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