Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage transmission line maintenance devices, in particular to a line hardware R-pin installation device. Background Art

[0002] High-voltage transmission lines are easily affected by the external environment and climatic conditions such as strong winds during operation. The R pins of line hardware often rust, wear, break, etc., causing the R pins to fall off. The conductors and hardware installed at high altitudes will vibrate and dance due to factors such as strong winds and other severe weather and operating environments. If the R pin of the hardware bolt is missing during vibration or dancing, the nut and bolt will fall off during the vibration. Once the bolt falls off, the conductor will fall off from the tower and cause the line to trip. Some lines often cannot be shut down for processing due to special reasons such as heavy load or single power supply. After the power outage, huge losses will be caused, and frequent operations will reduce the service life of the equipment and increase the workload of operators. Utility Model Content

[0031] like Figures 1-8 The shown device is an R-pin installation device for line hardware, comprising a telescopic insulating rod 1, a connecting rod 2, a hinged rod 4, a rotating rod 6 and an R-pin fixing fixture 7. The connecting rod 2 is detachably fixedly connected to the telescopic end of the telescopic insulating rod 1, the hinged rod 4 is hingedly connected to the end of the connecting rod 2 away from the telescopic insulating rod 1, and the two are tightened by a first fastening bolt 3. The end of the hinged rod 4 away from the connecting rod 2 is coaxially rotatably connected to the rotating rod 6, and the two are tightened and fixed by a second fastening bolt 5. The R-pin fixing fixture 7 is connected to the end of the rotating rod 6 away from the hinged rod 4.

[0032] Specifically, in the embodiment, the telescopic insulating rod 1 adopts a multi-stage telescopic rod structure, such as a multi-stage telescopic rod with a publication number of CN210423300U in the prior art and a waterproof multi-stage telescopic rod with a publication number of CN102494095B, which belongs to the prior art and is therefore not described in detail, and the multi-stage telescopic rod shell is made of an insulating material or an insulating sleeve is provided on the outer surface of the multi-stage telescopic rod to achieve an insulation function, and the outermost movable end of the telescopic insulating rod 1 and the connecting rod 2 are provided with mounting holes distributed in corresponding positions, such as Figure 1 and Figure 2 As shown, the two are detachably fixedly connected by bolts and nuts.

[0033] like Figure 2 、 Figure 3 As shown, the end of the connecting rod 2 away from the telescopic insulating rod 1 is hingedly connected to the hinged rod 4, and a first fastening bolt 3 is connected between the two. Specifically, mounting holes corresponding to the positions are provided on the hinged rod 4 and the connecting rod 2. The screw section of the first fastening bolt 3 passes through the connecting rod 2 and the hinged rod 4 through the mounting hole and is connected to a nut. When the angle between the hinged rod 4 and the connecting rod 2 needs to be adjusted, the nut is loosened. After the adjustment is completed, it is tightened by the nut to fix the position of the hinged rod 4 and the connecting rod 2.

[0034] like Figure 2 and Figure 5 As shown, the end of the hinged rod 4 away from the connecting rod 2 is coaxially connected to the rotating rod 6, and the end of the hinged rod 4 away from the connecting rod 2 is provided with a rotating hole, and one end of the rotating rod 6 can be rotatably connected to the inside of the rotating hole. A threaded hole is provided on the side wall of the rotating hole, and the axis of the threaded hole is distributed perpendicular to the axis of the rotating hole and is connected to the inside of the rotating hole. The threaded hole is also connected to a second fastening bolt 5, and the rotating rod 6 can be tightened by the second fastening bolt 5, thereby limiting the relative rotation between the rotating rod 6 and the hinged rod 4.

[0035] like Figure 1-Figure 4 as well as Figure 6 、 Figure 7 As shown, the end of the rotating rod 6 away from the hinge rod 4 is a plate-like structure parallel to the rotation plane between the hinge rod 4 and the connecting rod 2, and the plate-like structure is connected to an R-pin fixing fixture 7, which includes a fixture body 701. The fixture body 701 is a cylindrical structure as a whole, and its axis is distributed along the plate-like structure perpendicular to the end of the rotating rod 6, that is, perpendicular to the rotation plane between the hinge rod 4 and the connecting rod 2. Figure 6In the viewing direction, four groups of bayonet holes 702 are provided on the left end surface of the clamp body 701 along the circumferential direction. The four groups of bayonet holes 702 are evenly distributed at an angle of 90°, and the size of each group of bayonet holes is different. A circular groove is provided in the middle of the left end surface of the clamp body 701, i.e., at the center of the circle. The circular groove is coaxially distributed with the clamp body 701, and the bayonet holes 702 are connected to the inside of the circular groove from the outside to the inside. A clamping column 703 is also coaxially fixedly connected in the circular groove. The size of the clamping column 703 matches the diameter of the gripping portion of the R pin 10 so as to be used for matching and connecting with the R pin 10, such as Figure 7 As shown, in Figure 7 In the viewing direction, a rotation groove 704 is provided on the right end face of the clamp body 701, that is, the end face close to the rotating rod 6. The left end face of the rotating rod 6 is fixedly connected with a rotating column 601. The rotating column 601 is connected to the rotation groove 704 in coordination with the rotation. In addition, threaded holes corresponding to the coaxial distribution are provided on the rotating rod 6, the rotating column 601 and the clamping column 703. The third fastening bolt 8 passes through the threaded holes on the rotating rod 6 and the rotating column 601 from right to left in turn and is threadedly connected with the threaded hole on the clamping column 703. A fastening nut 9 is also provided, which is threadedly connected to the third fastening bolt 8. When the relative position relationship between the R-pin fixture 7 and the upper part of the rotating rod 6 needs to be adjusted, the fastening nut 9 can be loosened, and the third fastening bolt 8 can be screwed out of the clamping column 703. Then the R-pin fixture 7 is rotated as a whole along the axis of the rotating column 601. After the adjustment is completed, the third fastening bolt 8 is threadedly connected to the clamping column 703, and finally the fastening nut 9 is tightened on the right end face of the rotating rod 6, thereby fixing the third fastening bolt 8 and the R-pin fixing fixture 7.

[0036] like Figure 8 As shown, when using this device to fix the R pin 10, the operator first brings the two legs of the R pin 10 together so that they are located in the bayonet 701 of the corresponding size, and then engages the annular gripping portion of the R pin 10 with the clamping column 703 to complete the fixation of the R pin 10. When installing the R pin 10, the height of the R pin fixing fixture 7 can be adjusted by the telescopic insulating rod 1. The rotational connection relationship between the hinged rod 4, the connecting rod 2 and the telescopic insulating rod 1 can be used to adjust the positional relationship between the R pin fixing fixture 7 and the position to be installed in the left and right directions. The coaxial rotational connection relationship between the rotating rod 6 and the hinged rod 4 can be used to adjust the overall direction of the R pin fixing fixture 7. The rotational connection between the R pin fixing fixture 7 and the rotating rod 6 can be used to adjust the direction of the R pin 10 legs on the R pin fixing fixture 7 so that it corresponds to the mounting hole on the component to be installed.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principles of the present invention. These improvements should also be regarded as within the scope of protection of the present invention.
