Description

Technical Field

[0001] The utility model relates to the technical field of power line detection, in particular to an online walking mechanism of a four-split conductor X-ray detection robot. 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 spaced a certain distance apart and arranged in a symmetrical polygon, and arranged at the vertices of the regular polygon. The number of split conductors of ordinary split conductors generally does not exceed 4, and it is mainly used in lines with voltages of 220 kV and above. Usually, split conductors are connected to elevated towers through tension clamps, but because the span between elevated towers is too large, the stress on the tension clamps will be very large. At the same time, in the case of long-term outdoor use, the tension clamps may crack, loosen, deform, and other problems. In order to ensure the stability of power transmission, it is necessary to inspect the tension clamps frequently.

[0003] In order to facilitate the rapid and safe detection of tension clamps in the prior art, drones are usually used to perform DR imaging detection on them. However, most of the devices are devices for detecting tension clamps on single-line clamps or multi-line clamps. When detecting split conductor lines, due to the long spacing between each phase of split conductors, the commonly used drone DR imaging detection robot can only detect the tension clamps on some of the split conductors at a time. If all detection is required, it needs to be hung on different conductors for detection multiple times, and the detection efficiency is low. In order to improve the detection efficiency, the applicant proposes a drone-based four-split conductor X-ray detection robot and detection method for improving the detection efficiency. Based on the detection robot, the present application provides an online walking mechanism of a four-split conductor X-ray detection robot. Utility Model Content

[0017] Example 1

[0018] like Figure 1 As shown, this embodiment provides an online walking mechanism of a four-split conductor X-ray inspection robot, which can be walked and hung on multiple groups of branch conductors with different spacings, thereby improving the scope of use of the mechanism. The mobile mechanism provided in this embodiment includes a rectangular hanger 2 and positioning parts arranged at the four corners of the lower end of the rectangular hanger 2, a rotating rod 7 is arranged between the two positioning parts at the front end and the two positioning parts at the rear end, and both ends of the rotating rod 7 rotate and penetrate the corresponding positioning parts, a power source for driving the rotating rod 7 to rotate is arranged on the rectangular hanger 2, and the rotating rod 7 is provided with a walking wheel group capable of hanging two branch conductors at the same horizontal height.

[0019] In this embodiment, the walking wheel group includes a walking wheel 3 sleeved on one end of a rotating rod 7 and a walking roller 8 sleeved on the other end of the rotating rod 7. In order to ensure the horizontal balance of the equipment, the outer circle side of the walking roller 8 is at the same level as the bottom side of the line groove of the walking wheel 3. In this embodiment, the length of the walking roller 8 is 10-30 cm, and the preferred length in this embodiment is 20 cm. The length of the walking roller 8 itself extends the hanging range of the equipment. It cooperates with the walking wheel 3 to make the original fixed hanging point become a variable hanging point at one end. No matter whether the spacing between the split conductors at the same level on the split conductor is large or small, it can be hung up, thereby improving the use range of the equipment.

[0020] When the mobile mechanism is moving, the power source controls the rotation of the rotating rod 7, thereby controlling the rotation of the walking roller 8 and the walking wheel 3. The walking wheel 3 and the walking roller 8 rely on the friction generated by the contact with the branch conductor during the rotation process, so as to drive the entire mechanism to move along the hanging branch conductor. In this embodiment, the power source includes two worm gear reduction motors, which are arranged near the two rotating rods 7, connected to the corresponding rotating rods 7, and fixedly arranged on the rectangular hanger 2. The transmission connection between the worm gear reduction motor and the rotating rod 7 is a prior art means, which will not be described in detail here.

[0021] In order to improve the friction force of the walking roller 8 in this embodiment, a friction pattern is provided on the circumference of the walking roller 8. This embodiment provides two specific shapes of the friction pattern, one of which is a friction pattern of a plurality of long strip grooves arranged in an array along the circumference of the walking roller 8. The other is a friction pattern of raised particles evenly distributed on the circumference of the walking roller 8.

[0022] In this embodiment, a reinforcement beam 6 is provided between the two positioning parts at the front end and the two positioning parts at the rear end. The stability of the positioning part is strengthened by providing the reinforcement beam 6. At the same time, in order to prevent the traveling wheel 3 from falling off the power transmission cable, a transmission rod 5 that can approach the traveling wheel 3 and a power source that drives the transmission rod 5 to rotate are rotatably provided on the reinforcement beam 6. The transmission rod 5 is L-shaped, and one end thereof is rotatably connected to the reinforcement beam 6 through a rotating shaft. A limiting wheel 4 is provided at the end of the transmission rod 5 away from the reinforcement beam 6, and the wire groove of the traveling wheel 3 is located in the rotation path of the limiting wheel 4. After the power transmission cable is located in the wire groove of the traveling wheel 3, the limiting wheel 4 is controlled to rotate by the power source so that the limiting wheel 4 is located below the traveling wheel 3 and moves to the wire groove of the traveling wheel 3 to prevent the traveling wheel 3 from falling off the power transmission cable.

[0023] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various modifications or variations within the scope of the claims, which does not affect the essence of the present invention.
