DETAILED DESCRIPTION
[0030] 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. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0032] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.
[0033] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

The pin nut 400 is threadedly connected to the pin 300. The end of the pin 300 is provided with a pin hole, and a pin 700 is installed in the pin hole. If the pin 700 is missing, a re-pinning operation is required. The re-pinning device 100 of the embodiment of the present invention is suitable for a re-pinning robot, and the re-pinning robot realizes the re-pinning operation by carrying a live-line operation lifting platform for transmission lines. The live-line operation lifting platform for transmission lines provides power for the re-pinning robot, and drives the re-pinning robot to move along the upper conductor 500. The re-pinning robot performs re-pinning operations after arriving at the fault location. The live-line operation lifting platform for transmission lines can adopt existing equipment, as long as it can provide power for the re-pinning robot and drive the re-pinning robot to move along the upper conductor 500.

The front end of the positioning seat 11 is provided with a first clamping groove 111 adapted to the pin shaft 300 and / or a second clamping groove 112 matched with the pin shaft nut 400. The positioning seat 11 is radially provided with a pin inlet hole 113 and a pin outlet hole 114. The pin inlet hole 113 and the pin outlet hole 114 are symmetrically arranged about the axis of the positioning seat 11. The pin inlet hole 113 is connected with the first clamping groove 111 and / or the second clamping groove 112, and the pin outlet hole 114 is connected with the first clamping groove 111 and / or the second clamping groove 112. The forming mechanism 30 includes a first forming block 31, a second forming block 32 and a horizontal driving assembly 33. The first forming block 31 is installed in the pin inlet hole 113.

The horizontal driving component 33 is installed on the mounting seat component 40. The horizontal driving component 33 is used to drive the positioning seat 11 to move in a direction away from the pin shaft 300, so that the first forming block 31 and the second forming block 32 move with the positioning seat 11 in a direction away from the pin shaft 300, thereby bending the two ends of the pin 700. The pin delivery mechanism 20 is installed on the first forming block 31, and the outlet end of the pin delivery mechanism 20 is connected to the first forming hole 311.
[0036] Optionally, when the length of the pin shaft 300 is longer, the positioning seat 11 can cooperate with the pin shaft 300, and only the first slot 111 is set on the positioning seat 11; when the length of the pin shaft 300 is shorter and there is no position on the pin shaft 300 to cooperate with the positioning seat 11, only the second slot 112 can be set on the positioning seat 11, or the first slot 111 and the second slot 112 can be set on the positioning seat 11 at the same time. At this time, the first slot 111 cooperates with the pin shaft 300, and the second slot 112 cooperates with the pin shaft nut 400.
[0037] It can be understood that the position of the locating seat 11 on the pin shaft 300 and the pin shaft nut 400 is pre-set, that is, the position and depth of the first slot 111 and the position and depth of the second slot 112 are set according to the distance between the pin hole and the end face of the pin shaft 300 or the distance between the pin hole and the pin shaft nut 400. As long as the locating seat 11 is mounted on the pin shaft 300 and the pin shaft nut 400, the rotating locating seat 11 can align the pin hole 113 with the pin hole of the pin shaft 300.
[0038] Please refer to the figure. In this embodiment, a connecting plate 50 is provided on the pin-replenishing device 100, and the mounting seat assembly 40 is installed on the mechanical arm through the connecting plate 50. The connecting plate 50 is slidably connected to the mounting seat assembly 40, and the connecting plate 50 is connected to the mounting seat assembly 40 through a first elastic member (not shown in the figure), that is, when the horizontal driving assembly 33 drives the positioning seat 11 to move in a direction away from the pin shaft 300, the mounting seat assembly 40 slides relative to the connecting plate 50, the first elastic member is stretched, and the pin-replenishing device 100 is adaptively adjusted relative to the mechanical arm.
[0039] Specifically, the first elastic member is a tension spring.
[0040] The pin replenishing device 100 of the embodiment of the present invention is provided with a positioning mechanism 10, a pin feeding mechanism 20 and a forming mechanism 30. The forming mechanism 30 includes a first forming block 31 and a second forming block 32. When replenishing the pin, the pin inlet hole 113 and the pin outlet hole 114 of the positioning mechanism 10 are aligned with the pin hole of the pin shaft 300, and then the pin 700 is inserted into the pin hole through the pin feeding mechanism 20. Since the outlet end of the pin feeding mechanism 20 is connected with the first forming hole 311 of the forming mechanism 30, after the pin 700 is inserted into the pin hole, the two ends of the pin 700 are respectively located in the first forming hole 311 of the first forming block 31 and the second forming hole 321 of the second forming block 32. The horizontal driving assembly 33 drives the positioning seat 11 to move in a direction away from the pin shaft 300, and the first forming block 31 and the second forming block 32 can bend the two ends of the pin 700, so that the pin 700 can be firmly installed in the pin hole, thereby reducing the risk of falling off.

[0054] It should be noted that, when used, the pin replenishing device 100 is installed on a robotic arm (not shown), and the robotic arm drives the pin replenishing device 100 to perform lifting and translational movements relative to the pin shaft 300 so that the front end of the positioning seat 11 is sleeved on the pin shaft 300 or the pin shaft nut 400, and the rotation drive component 13 drives the positioning seat 11 to rotate. During the rotation of the positioning seat 11, the detection sensor 12 detects the position of the pin hole. After detecting the pin hole, the rotation drive component 13 drives the positioning seat 11 to rotate a preset angle (for example, 90 degrees) to align the pin delivery hole on the positioning seat 11 with the pin hole, and then the pin delivery mechanism 20 inserts the pin 700 into the pin hole of the pin shaft 300, and finally the forming mechanism 30 bends the two ends of the pin 700 to complete the pin replenishing operation.
[0055] See also Figure 5As shown, exemplarily, in some embodiments, the detection sensor 12 is a through-beam photoelectric sensor, and the detection sensor 12 includes a transmitter 121 and a receiver 122. The positioning seat 11 is provided with a first through-hole 115 and a second through-hole 116, and the first through-hole 115 and the second through-hole 116 are symmetrically arranged about the axis of the positioning seat 11. The transmitter 121 is installed in the first through-hole 115, and the receiver 122 is installed in the second through-hole 116. When the positioning seat 11 is rotated to align the first through-hole 115 with the pin hole, the laser emitted by the transmitter 121 can be received by the receiver 122, and at this time, the position of the pin hole can be determined.
[0056] It can be understood that the preset angle of rotation of the rotation drive component 13 to drive the positioning seat 11 is related to the positional relationship between the detection sensor 12 and the pin entry hole 113. For example, if the detection sensor 12 and the pin entry hole 113 differ by 90 degrees, then the preset angle of rotation is 90 degrees.
