Abstract
Description
Technical Field
[0001] This utility model relates to the field of non-destructive testing technology for power transmission lines, specifically an adjustable support component and a six-eight split conductor flaw detection robot. Background Technology
[0002] In power transmission lines, splicing tubes and tension clamps are key fittings requiring crimping, and conductor crimping is a core aspect of line construction. Tension clamps, in particular, must withstand the full tension of the conductor while also providing conductivity; therefore, a combination structure of steel anchors and aluminum tubes is used. The main methods for crimping these fittings are hydraulic and burst crimping. While burst crimping is fast and requires no specialized equipment, the quality is difficult to control and poses safety risks, leading to its gradual phasing out in the industry. Hydraulic crimping, due to its higher safety, is more widely used in engineering. Faults in crimping fittings (such as broken steel cores or missing anti-slip grooves) are often not directly identifiable by appearance, easily leading to the use of defective fittings and creating hidden dangers for line operation. This is especially true under extreme conditions such as icing and galloping, where the stress on crimping fittings increases, making defective fittings highly susceptible to failure and threatening power grid safety.
[0003] With technological advancements, X-ray inspection technology is increasingly being used for quality inspection of crimped fittings. It can effectively examine the internal condition of the fittings, providing support for hazard identification. For example, Chinese patent CN115656229A provides a drone-based X-ray inspection device for tension clamps. This device can be lifted and transported to the tension clamp location by a drone, and the inspection equipment on the device can be remotely activated to obtain the inspection results. After inspection, the entire device is hoisted back to the ground. This inspection device can replace traditional high-altitude operations, reducing safety risks. However, this inspection device requires drone hoisting and movement, resulting in relatively low efficiency.
[0004] Therefore, the applicant developed a multi-split wire crawling flaw detection robot, which automatically crawls along the wire using wheels, significantly improving detection efficiency. However, in practical applications, especially in the detection of six-split wires, when the wheels are suspended above the outermost sub-wire, the robot tilts due to the lack of wire support below, making it impossible to detect the two outermost sub-wires. Utility Model Content
[0005] The purpose of this invention is to provide an adjustable support assembly and a six-eight split wire flaw detection robot. The assembly is installed on the side wall of the flaw detection robot and provides stable support for the robot through the telescopic rod on the assembly, ensuring that the robot can successfully detect the two outermost sub-wires.
[0006] To achieve the above objectives, the specific solution adopted by this utility model is as follows: an adjustable support assembly includes a base and a frustum. The frustum is rotatably connected to the base on the same axis and can be locked by a locking unit. The locking unit includes a locking member. The base is provided with a plurality of circumferentially distributed adjustment holes. A locking hole is opened on the frustum. The locking member passes through the locking hole and any one of the adjustment holes in sequence to lock the position of the frustum. A support unit is provided on the frustum. The support unit includes a mounting cylinder fixedly connected to the frustum. A telescopic rod coaxial with the mounting cylinder and driven by a drive source is slidably provided on the mounting cylinder.
[0007] As an optimized solution for the aforementioned adjustable support component: at least one rotating sleeve is rotatably sleeved on the telescopic rod.
[0008] As another optimization of the aforementioned adjustable support component: the number of rotating sleeves is multiple and they are distributed along the length of the telescopic rod. The telescopic rod has multiple annular grooves that correspond one-to-one with the rotating sleeves, and the rotating sleeves are located in the annular grooves.
[0009] As another optimization of the aforementioned adjustable support component: the outer wall of the rotating sleeve is wrapped with a rubber ring.
[0010] As another optimized solution for the aforementioned adjustable support component: a blind hole is provided at the center of the frustum, and a central shaft is coaxially fixed at the center of the base, with the central shaft extending into the blind hole and connected by a bearing.
[0011] As another optimized solution for the aforementioned adjustable support component: the locking element is a bolt, and the adjusting hole has an internal thread that matches the external thread of the bolt.
[0012] To achieve the above objectives, this utility model also adopts a specific solution as follows: a six-eight split wire flaw detection robot, including a chassis, a hoisting mechanism, a walking mechanism and a flaw detection mechanism, wherein the chassis is provided with an adjustable support component as described in any of the above solutions.
[0013] As an optimized solution for the aforementioned six-eight split wire flaw detection robot: the hoisting mechanism includes two parallel vertical rods, with a horizontal rod erected between the two vertical rods.
[0014] As another optimized solution for the aforementioned six-eight split wire flaw detection robot: the walking mechanism includes two walking wheels and a power component for driving the walking wheels.
[0015] As another optimized solution for the aforementioned six-eight split wire flaw detection robot: the flaw detection mechanism includes a support frame, an X-ray machine, and an imaging plate.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] 1. This utility model provides an adjustable support component and a six-eight split wire flaw detection robot. Before detecting the two side sub-wires, a locking member is used to pass through the locking hole and fix it to an adjustment hole on the base, thereby fixing the position of the truncated cone. When detecting the two side sub-wires, the telescopic rod can extend from the mounting cylinder to provide stable support for the robot. When detecting the middle wire or not detecting it, the telescopic rod is retracted into the mounting cylinder without affecting the operation of the robot.
[0018] 2. Since the entire device will move along the conductor, a rotating sleeve is provided on the telescopic rod to reduce the friction between the telescopic rod and the conductor. Attached Figure Description

[0028] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as how the drive source drives the reciprocating motion of the telescopic rod, the structure of the flaw detection robot, etc.
[0029] Example 1
[0030] Please see Figures 1-6 An adjustable support assembly includes a circular disc-shaped base 2 and a frustum 5. The frustum 5 and the base 2 are coaxially rotatably connected by a rotating assembly. In this embodiment, the rotating assembly includes a central shaft 3 located at the center of the base 2 and a blind hole 12 located at the center of the frustum 5, as well as a bearing 4 connecting the central shaft 3 and the blind hole 12. The bearing 4 is located inside the blind hole 12, and the outer ring of the bearing 4 is fixedly connected to the outer wall of the blind hole 12. The connection between the two is an interference fit. The end of the central shaft 3 away from the base 2 extends into the inner ring of the bearing 4 and is fixedly connected to the inner ring of the bearing 4, thereby realizing the rotatable connection between the base 2 and the frustum 5.
[0031] The base 2 and the frustum 5 can be locked by a locking unit, which includes a locking element 13. Specifically, the base 2 is provided with a plurality of circumferentially distributed adjustment holes 1. In this embodiment, the number of adjustment holes 1 is 5. The frustum 5 is provided with a locking hole 6. In this embodiment, the locking element 13 is a bolt. The adjustment hole 1 is provided with an internal thread that matches the external thread of the bolt. The locking element 13 can pass through the locking hole 6 and any one of the adjustment holes 1 on the base 2 in sequence to lock the position of the frustum 5.
[0032] A support unit is provided on the frustum 5. The support unit can be an electric push rod or other telescopic structure. In this embodiment, the support unit includes a mounting cylinder 7 fixedly connected to the frustum 5. A telescopic rod 8, coaxial with the mounting cylinder 7 and driven by a drive source 14, is slidably mounted on the mounting cylinder 7. The drive source 14 is fixedly connected to the side wall of the mounting cylinder 7. The drive source 14 can be a motor or a cylinder. The drive source 14 drives the telescopic rod 8 to perform linear telescopic movement along its length. In the retracted state, the telescopic rod 8 is fully extended into the mounting cylinder 7. How the drive source 14 drives the telescopic rod 8 to reciprocate is prior art and is well known to those skilled in the art; therefore, its driving principle will not be described again here.
[0033] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:
[0034] Example 2
[0035] This embodiment is an improvement on Embodiment 1. Its main structure is the same as Embodiment 1, but the improvement lies in that at least one rotating sleeve 11 is rotatably fitted onto the telescopic rod 8. In this embodiment, there are four rotating sleeves 11, and four annular grooves 9 corresponding one-to-one with the rotating sleeves 11 are formed on the telescopic rod 8. The rotating sleeves 11 are located within the annular grooves 9. During the movement of the traveling wheel 18 along the guide wire, the telescopic rod 8 moves along the guide wire it contacts. The rotating sleeves 11 effectively reduce friction between the telescopic rod 8 and the guide wire, preventing wear on the guide wire.
[0036] The outer wall of the rotating sleeve 11 is wrapped with a rubber ring 10, which facilitates the rotation of the rotating sleeve 11 along the wire, and the telescopic rod 8 makes flexible contact with the wire to further protect the wire and prevent damage to the wire.
[0037] Example 3
[0038] Please see Figure 7 and Figure 8 A six-eight split wire flaw detection robot includes a chassis 15, a hoisting mechanism, a walking mechanism, and a flaw detection mechanism. The chassis 15 is fixedly connected to an adjustable support assembly as described in Embodiment 1 or Embodiment 2. The hoisting mechanism includes two parallel vertical rods 16, and a horizontal rod 17 is erected between the two vertical rods 16. The horizontal rod 17 is a V-shaped rod, and its two ends are welded to the upper ends of the two vertical rods 16. The connection is an arc structure. The plane of the V-shaped rod forms an angle of 45-65° with the plane of the two vertical rods. This angle setting facilitates the entry of the drone's boom into the V-shaped rod for hoisting.
[0039] The walking mechanism includes two walking wheels 18 and a power component 19 that drives the walking wheels 18. The walking wheels 18 are V-grooved wheels. During testing, the walking wheels 18 remain on the guide wire. The power component 19 is a drive motor. When the robot needs to be moved, the drive motor starts to rotate, driving the walking wheels 18 to rotate synchronously and move forward or backward along the guide wire.
[0040] The flaw detection mechanism includes a support frame 20, an X-ray camera 21, and an imaging plate 22. The imaging plate 22 and the X-ray machine 21 are respectively set at the upper and lower parts of the support frame 20. The imaging plate 22 can be flipped on the support frame 20 through a flipping assembly. During the inspection, the wire is placed between the imaging plate 22 and the X-ray camera 21, and the flaw detection operation of the wire can be performed.
[0041] The wire inspection robot described above (including its overall structure, basic motion mode and conventional control logic) is existing technology, so the specific structure and basic functions of the wire inspection robot will not be described in further detail here.
[0042] Six-split conductor detection method
[0043] Please see Figure 8 The support assembly is installed on the side wall of the six-split wire flaw detection robot. Before operation, the truncated cone is locked by using locking parts to pass through the locking hole and adjustment hole in sequence, according to the direction of the telescopic rod to be set.
[0044] When starting work, the flaw detection robot is hoisted above the side guide wire, so that the robot's wheels are mounted on the guide wire. At this time, the telescopic rod is remotely controlled to extend from the mounting cylinder and extend to the bottom of the upper guide wire. Due to the obstruction of the telescopic rod, the entire device will not flip. After the device is stable, the imaging plate is controlled to flip and finally reach a horizontal state, so that the guide wire is between the X-ray machine and the imaging plate, and the flaw detection operation of the guide wire can be carried out.
[0045] When the robot needs to walk on the guide wire, the telescopic rod moves synchronously with the robot to provide stable support. The rotating sleeve on the telescopic rod rotates along the guide wire, which can reduce the friction between the telescopic rod and the guide wire.
[0046] After the inspection is completed, the telescopic pole is retracted via remote control, and then a drone is used to lift the flaw detection robot to the ground.
[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
