[0002] In power transmission lines, pin bolts and dowels are widely used as fasteners to ensure the stability of the entire structure. However, due to the complex working environment of transmission lines, they often swing in strong winds. In addition, due to the non-standard production specifications of hardware such as pin bolts and suspension clamps, the pin eye of the pin bolt is too large and the opening curvature of the R-type pin is not in place, which leads to the serious loss of pins on the pin bolts. If not handled in time, the pin bolts may gradually fall off, which is very likely to cause large-scale power transmission line failures and seriously threaten the safety and stability of the power grid.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] For ease of understanding, the specific structure and working mode of the utility model are further described below in conjunction with the accompanying drawings:
[0031] The specific structure of the utility model refers to Figure 1-6 As shown, its main structure includes a working part for reinstalling the R-type pin a on the pin bolt b on the cable and a hand-held part for the staff to hold and adjust the working angle of the working part.
[0032] Among them, Figure 2 As shown, the working part includes a housing 20, and a bolt insertion hole 21 matching the outer diameter of the pin shaft bolt b is arranged on the top of the housing 20. In addition, a camera and acquisition assembly 50 and a positioning push pin assembly 30 for positioning and loading the R-type pin a are respectively arranged on both sides of the bolt insertion hole 21 at the top of the housing 20. After the R-type pin a is loaded onto the positioning push pin assembly 30, the bolt insertion hole 21 of the housing 20 is sleeved on the end of the pin shaft bolt b; thereafter, the camera and acquisition assembly 50 is used to determine whether the movement path of the R-type pin a is coaxially distributed with the pin hole of the pin shaft bolt b. If they are coaxially distributed, the sliding end of the positioning push pin assembly 30 pushes the R-type pin a to slide along the acquisition path of the camera and acquisition assembly 50 and radially plug into the pin hole of the pin shaft bolt b.
[0033] like Figure 6As shown, the hand-held part includes a multi-angle adjustment rod 10 that can be bent and adjusted to an angle, and a shell 20 is connected to the first end of the multi-angle adjustment rod 10. The multi-angle adjustment rod 10 is bent and adjusted to an angle to achieve a rough alignment between the bolt hole 21 and the pin bolt b on the cable, so as to facilitate the subsequent manual control of the position of the multi-angle adjustment rod 10, and finally achieve the precise sleeve of the bolt hole 21 on the end of the pin bolt b.
[0034] In order to facilitate the alignment of the movement path of the R-type pin a with the pin hole axis of the pin bolt b, on the basis of the above, the shell 20 can make a rotational motion around the first end axis of the multi-angle adjustment rod 10, and the first end axis is coaxially distributed with the bolt insertion hole 21. Therefore, when the pin hole axis of the pin bolt b is inconsistent with the movement path of the R-type pin a, the shell 20 rotates around the axis of the bolt insertion hole 21, so as to align the movement path of the R-type pin a with the pin hole of the pin bolt b at the pre-installation station of the cable, thereby realizing the subsequent plug-in operation of the R-type pin a.
[0035] Specifically, Figure 2 and Figure 3 As shown, the positioning push pin assembly 30 includes two sets of clamping guide rollers 33, a push pin member 32 constituting a sliding end, and an electric telescopic rod 31 for pushing the push pin member 32 to perform reciprocating motion.
[0036] Among them, the two sets of clamping guide rollers 33 are arranged near the bolt insertion hole 21 and are spaced apart on both sides of the R-type pin a. During the plugging process, the movement of the open end of the R-type pin a can be guided and the opening degree of the open end of the R-type pin a can be compressed, so that the open end of the R-type pin a can accurately and smoothly pass through the pin hole of the pin shaft bolt b. In addition, due to the compression of the open end of the R-type pin a by the two sets of clamping guide rollers 33, the open end of the R-type pin a has an elastic tension that opens toward the two sets of clamping guide rollers 33, thereby elastically positioning the position of the open end of the R-type pin a.
[0037] The push member 32 includes a push plate 322 that slides on the top of the housing 20 along the sliding direction of the R-type pin a. The forward end of the push plate 322 is provided with a tail groove 3221 that matches the tail of the R-type pin a. The tail groove 3221 locates the tail position of the R-type pin a, and cooperates with the outer edges of the two sets of clamping guide rollers 33 to achieve the positioning of the R-type pin in the front, back, left and right directions. In addition, an upper positioning plate 321 that locates the upper position of the R-type pin a is fixed to the top of the push plate 322. The upper positioning plate 321 and the top of the housing 20 realize the positioning of the upper and lower positions of the R-type pin a. Therefore, the groove wall of the tail groove 3221, the lower plate surface of the upper positioning plate 321, the top surface of the housing 20 and the outer edges of the two sets of clamping guide rollers 33 together form a positioning area for locating the position of the R-type pin a. When the R-type pin a is loaded on the positioning push pin assembly 30 , it is only necessary to insert the R-type pin a from the gap between the two sets of clamping guide rollers 33 until its tail end abuts against the tail groove 3221 .
[0038] On the basis of the above, if Figure 2 As shown, a connecting slide bar 323 penetrating into the interior of the housing 20 is fixed at the bottom of the push plate 322, and a long hole 22 for the connecting slide bar 323 to slide is provided at the top of the housing 20; in addition, the electric telescopic rod 31 is arranged in the inner cavity of the housing 20, and the telescopic end of the electric telescopic rod 31 is fixed to the connecting slide bar 323. By embedding the electric telescopic rod 31 in the housing 20, the interference of the electric telescopic rod 31 on the top area of the housing 20 is effectively reduced, which facilitates better plug-in matching between the pin bolt b and the bolt insertion hole 21.
[0039] In addition, if Figure 4 and Figure 5 As shown, in order to quickly and accurately make the pin hole axis of the pin bolt b and the movement path of the R-type pin a in the same plane, a bolt positioning assembly 40 is provided in the inner end of the bolt insertion hole 21 of the inner cavity of the housing 20 to accurately locate the position where the end of the pin bolt b is inserted into the bolt insertion hole 21, thereby locating the pin hole position of the pin bolt b. In addition, the bolt positioning assembly 40 includes a bearing seat 41 fixed to the housing 20 and a stop pad 42 that rotates around the axis of the bolt insertion hole 21 through a bearing, and the stop pad 42 is abutted against the end of the pin bolt b, so that when the housing 20 rotates, the pin bolt b and the stop pad 42 are abutted, thereby making the pin bolt b and the stop pad 42 rotate synchronously, and the rolling friction of the bearing between the stop pad 42 and the bearing seat 41 is used to reduce the friction resistance between the housing 20 and the pin bolt b during the rotation process.
[0040] On the basis of the above, if Figure 2 As shown, the inner cavity of the housing 20 is fixedly connected with a rotary motor 60, and the output shaft of the rotary motor 60 is coaxially fixedly connected with the first end of the multi-angle adjustment rod 10, and the housing 20 is driven by the rotary motor 60 to rotate around the first end axis of the multi-angle adjustment rod 10, without manually pushing the housing 20 to rotate. In practice, the rotary motor 60 is preferably a servo motor or a stepper motor.
[0041] In addition, if Figure 2 As shown, a power supply 80 for powering the camera acquisition component 50, the electric telescopic rod 31 and the rotating motor 60 is installed in the housing 20, so there is no need to connect wires to an external power source. In addition, a charging port 81 for charging the power supply 80 is provided on the housing 20, which is used to charge the power supply 80, and a power switch 90 for turning on and off the power supply 80 is also provided on the housing 20.
[0042] Specifically, a control module 70 powered by a power supply 80 is installed in the shell 20. The control module 70 is used to receive the acquisition signal of the camera acquisition component 50, and control the electric telescopic rod 31 and the rotating motor 60 to perform corresponding driving operations according to the received acquisition signal, so as to realize the automated pin installation operation.
[0043] On the basis of the above, if Figure 6 As shown, the multi-angle adjustment rod 10 includes a first joint rod 13 coaxially fixed with the output shaft of the rotating motor 60, a second joint rod 12 hinged to the cantilever end of the first joint rod 13 through a first radial hinge seat, a link rod head 11 hinged to the cantilever end of the second joint rod 12 through a second radial hinge seat, and an insulating rod detachably mounted on the cantilever end of the link rod head 11. Specifically, the link rod head 11 and the insulating rod are detachably connected by threaded connection. Among them, the axis of the hinge of the first radial hinge seat is perpendicular to the axis of the second radial hinge seat. The staff holds the insulating rod and bends the second joint rod 12 around the axis of the first radial hinge seat or bends the insulating rod around the second radial hinge seat to achieve angle adjustment in the X-axis and Y-axis directions respectively. In addition, the second joint rod 12 is provided with set screws that respectively prevent the first radial hinge seat and the second radial hinge seat from rotating, and the locking after the above-mentioned angle adjustment is achieved by the set screws.
[0044] Of course, in actual implementation, the multi-angle adjustment rod 10 can also be implemented in other ways, such as setting a first joint rod 13 coaxially fixed with the output shaft of the rotating motor 60, the cantilever end of the first joint rod 13 is directly connected to the link rod head 11 through a universal ball joint, and a locking screw of the anti-rotation universal ball joint is provided.
[0045] Of course, for those skilled in the art, the present invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes that fall within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
[0046] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
