[0001] The present invention relates to the technical field of live working, and in particular to a special tool based on blind installation of a ground potential R pin. Background Art

[0002] Currently, R pins are widely used in power transmission and play a vital role. However, due to vibration of insulators and conductors, as well as aging of the material itself, they can fall off. Reinstalling them at equal potentials is time-consuming and labor-intensive. In particularly complex locations, reinstallation requires power outages, impacting power supply reliability.

[0003] The utility model patent with application number: 201821648496.3 discloses a live reinstallation tool for R-type spring pins, comprising: an adjusting bolt, a shell and an insulating handle; wherein the working end of the shell is a free end, and the other end of the shell is fixedly connected to the insulating handle; a pin accommodating chamber for accommodating R-type spring pins is opened on one side of the free end of the shell along the radial direction of the shell, thereby solving the problem that R-type spring pins cannot be reinstalled live.

[0004] Although the above utility model patent solves the problem that the R-type spring pin cannot be reinstalled under power, the installer needs to push and pull the insulating handle back and forth to complete the installation of the R-type spring pin, which results in low installation efficiency in actual use. Summary of the Invention

[0005] The present invention provides a special tool for blind installation of an R-type spring pin based on ground potential, aiming to solve the problem in related technologies that installers need to push and pull the insulating handle back and forth to complete the installation of the R-type spring pin.

[0006] The special tool for blind installation of ground potential R pins of the present invention includes a shell, one end of the shell is rotatably connected to an R pin placement part, the R pin placement part is provided with an R pin placement groove, the other end is provided with an insulating push rod, and the side wall of the shell is provided with an inclined slide groove. The insulating push rod passes through the end wall of the shell and is slidably connected to the inclined slide groove. During the installation of the R pin, the insulating push rod drives the shell to rotate, the R pin placement part is provided with a fastening part, which is used to apply pressure to the R pin in the R pin placement part to close the open end of the R pin, and the shell is provided with an adjusting part adapted to the fastening part. During the rotation of the shell, the adjusting part controls the fastening part to release the pressure on the open end of the R pin.

[0007] By adopting the above technical solution, the beneficial effects of the present invention are as follows: the closed end of the R pin is facing the insulating push rod and placed in the R pin placement groove, the open end of the R pin is closed by applying pressure through the fastening part, the R pin is aligned with the pin installation point, and the insulating push rod is pushed, so that the R pin can be completely installed into the installation point, and the R pin is automatically disengaged from the R pin placement groove, solving the problem that the installer needs to push and pull the insulating handle back and forth to complete the installation of the R-type spring pin.

[0008] Preferably, the fastening portion is a bolt threadedly connected to the R-pin placement portion.

[0009] Preferably, the adjustment portion is an adjustment groove provided on the housing, which is provided on the side wall of the housing at one end close to the bolt and contacts the bolt. During the rotation of the housing, the adjustment groove squeezes the bolt to rotate back toward the outside of the R-pin placement portion.

[0010] By adopting the above technical solution, the beneficial effect of the present invention is: by pushing the insulating push rod, the rotation of the outer shell can be controlled, and the bolt is squeezed by the adjustment groove and rotates back toward the outside of the placement part, thereby releasing the pressure on the open end of the R pin and breaking away from the contact with the R pin, so that the R pin automatically detaches from the R pin placement groove.

[0011] Preferably, the fastening part also includes a fastening rod connected to the R-pin placement part via an elastic member, the fastening rod having an external part placed outside the R-pin placement part and an internal part, the internal part passes through the side wall of the R-pin placement part and is placed in the R-pin placement groove, the internal part is closed by elastic squeezing of the elastic member through the R-pin open end, and the diameter of the external part of the fastening rod gradually decreases from the top to the bottom of the fastening rod.

[0012] Preferably, the adjustment portion further comprises an adjustment ring arranged on the housing, the adjustment ring being arranged near one end of the fastening rod and in contact with the external portion of the fastening rod, and the diameter of the side of the adjustment ring in contact with the fastening rod increases circumferentially.

[0013] Preferably, the elastic member is a spring, which is sleeved on the built-in portion of the fastening rod, with one end fixedly connected to the inside of the R pin placement slot and the other end fixedly connected to the built-in portion of the fastening rod.

[0014] By adopting the above technical solution, the beneficial effect of the present invention is that the rotation of the outer shell can drive the rotation of the adjustment ring. During the rotation of the adjustment ring, the edge diameter of the contact part between the external part of the fastening rod and the adjustment ring gradually increases, thereby driving the adjustment rod to move away from the R-pin placement part, thereby releasing the pressure on the open end of the R-pin and breaking away from the contact with the R-pin.

[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] like Figure 1 As shown, the special tool for blind installation of ground potential R pin of the present invention comprises a housing 10, one end of the housing 10 is rotatably connected to an R pin placement portion 20, an R pin placement groove 21 is provided on the R pin placement portion 20, and an insulating push rod 40 is provided on the other end. An inclined slide groove 11 (as shown in FIG. Figure 1 As shown), the insulating push rod 40 passes through the end wall of the shell 10 and is slidably connected to the inclined slide groove 11. A slider is slidably connected to the inclined slide groove 11. One end of the slider is fixedly connected to the part of the insulating push rod placed in the shell 10. During the installation of the R pin, the insulating push rod 40 drives the shell 10 to rotate. The R pin placement portion 20 is provided with a fastening portion 30, which is used to apply pressure to the R pin in the R pin placement portion 20 to close the open end of the R pin. The shell 10 is provided with an adjusting portion 12 adapted to the fastening portion 30. During the rotation of the shell 10, the adjusting portion 12 controls the fastening portion 30 to release the pressure on the open end of the R pin.

[0022] In this specific embodiment, the closed end of the R pin is facing the insulating push rod 40 and placed in the R pin placement groove 21. The open end of the R pin is closed by applying pressure through the fastening part 30, the R pin is aligned with the pin installation point, and the insulating push rod 40 is pushed. During the pushing process, the insulating push rod 40 is placed at one end inside the shell 10 and translates toward the direction of the R pin placement part 20. During the translation process, the shell 10 rotates synchronously with the movement of the insulating push rod 40 through the inclined slide groove 11. During the rotation of the shell 10, the adjustment part 12 is driven to apply pressure to the fastening part 30, driving the fastening part 30 to release the pressure on the open end of the R pin and separate from the R pin. The separation process is carried out synchronously with the process of the staff inserting the R pin into the installation point. Therefore, when the R pin is fully installed into the installation point, the R pin is automatically disengaged from the R pin placement groove 21, solving the problem that the installer needs to push and pull the insulating handle back and forth to complete the installation of the R-type spring pin.

[0023] like Figures 2 to 3 As shown, the fastening portion 30 is a bolt 31 threadedly connected to the R-pin placement portion 20, and an anti-slip layer can be provided at one end of the bolt to improve stability during the process of applying pressure to the open end of the R-pin.

[0024] like Figures 2 to 3 As shown, further, the adjustment portion 12 is an adjustment groove 121 provided on the housing 10. The adjustment groove 121 is provided on the side wall of the housing 10 near one end of the bolt 31 and contacts the bolt 31. During the rotation of the housing 10, the adjustment groove 121 squeezes the bolt 31 and rotates back toward the outside of the R-pin placement portion 20. When one end of the insulating push rod 40 moves toward the direction of the R-pin placement portion 20, the adjustment groove 121 squeezes the nut of the bolt 31 to rotate, driving the thread of the bolt 31 to rotate and causing the end of the bolt 31 to gradually move away from the R-pin.

[0025] like Figure 4 As shown, preferably, the fastening portion 30 also includes a fastening rod 33 connected to the R-pin placement portion 20 via an elastic member 32, and the fastening rod 33 has an external portion placed outside the R-pin placement portion 20 and an internal portion, the internal portion passes through the side wall of the R-pin placement portion 20 and is positioned in the R-pin placement groove 21, the internal portion is closed by the elastic squeezing of the elastic member 32 on the open end of the R-pin, and the diameter of the external portion of the fastening rod 33 gradually decreases from the top to the bottom of the fastening rod 33.

[0026] like Figure 4 As shown, specifically, the adjustment portion 12 also includes an adjustment ring 122 arranged on the outer shell 10, and the adjustment ring 122 is arranged at one end close to the fastening rod 33 and contacts the external portion of the fastening rod 33. The side of the adjustment ring 122 that contacts the fastening rod 33 has an edge diameter that increases circumferentially. When the insulating push rod 40 moves in a direction away from the R-pin placement portion 20, the minimum diameter of the edge of the adjustment ring 122 contacts the fastening rod 33. At this time, the fastening rod applies pressure to the R-pin placed inside and closes the open end of the R-pin. Otherwise, the maximum diameter contacts the fastening rod 33. When the maximum diameter contacts the fastening rod 33, the pressure of the fastening rod 33 on the open end of the R-pin is ended, and the fastening rod is separated from the R-pin.

[0027] like Figure 4 As shown, further, the elastic member 32 is a spring 321, and the spring 321 is sleeved on the built-in part of the fastening rod 33, one end of the spring is fixedly connected to the inside of the R-pin placement slot 21, and the other end is fixedly connected to the built-in part of the fastening rod 33. When the spring 321 is stationary, its elastic force drives the fastening rod 33 to extend in the direction of the spring 321 in the direction of the R-pin placement slot 21. The elastic force of the spring 321 is greater than the elastic force of the conventional R-pin open end, so that when the spring 321 drives the fastening rod 33 to move in the direction of the R-pin placement slot 21, it can apply pressure to the R-pin placed inside it to close the R-pin open end.
