Technical Field

[0001] The utility model relates to the technical field of head iron bolt installation, in particular to an operating tool for reinstalling and tightening head iron bolts of power distribution lines. Background Art

[0002] The head iron is installed vertically on the cross arm and fixed to the upper side of the pole through the head iron clamp. It is used to support the insulator and the conductor, so as to ensure sufficient insulation between the conductor and the cross arm and the pole. The head iron should be able to withstand the vertical load of the conductor and the lateral tension of the conductor during operation. It must also withstand wind load, snow load, conductor dancing and other loads in severe weather conditions. Therefore, the screw sleeve must be tightened or reinstalled during the installation process. The head iron is usually installed on the pole with bolts.

[0028] Reference Figure 1 As shown, the utility model provides a technical solution: a tool for repairing and tightening iron bolts at the head of a distribution line, comprising an insulating rod 1, an insulating handle 3 is fixedly installed on the side wall of the insulating rod 1, a bolt sleeve 2 is fixedly installed on the upper end of the insulating rod 1, a collecting structure 4 is provided on the side wall of the insulating rod 1, and an adjustment structure 5 is provided on the surface of the bolt sleeve 2.

[0029] The specific settings and functions of the collection structure 4 and the adjustment structure 5 are described in detail below.

[0030] Reference Figure 1-Figure 2 and Figure 4 As shown, in this embodiment: the collection structure 4 includes a black plastic sheet 41 fixedly connected to the side wall of the insulating rod 1, an elastic rope 42 is fixedly installed on the upper end of the black plastic sheet 41, and a push rod 48 is slidably connected to the inside of the insulating rod 1 and the bolt sleeve 2. The fallen nuts will fall into the inner side of the stretched black plastic sheet 41, which facilitates the collection of nuts during the process of refitting or locking the nuts. The side wall of the insulating rod 1 is fixedly connected with six limit blocks 44 in groups of two, and the side of the two limit blocks 44 close to each other is rotatably connected with a support bar 43, and the lower sides of the three support bars 43 are fixedly connected to the side wall of the elastic rope 42. The three support bars 43 will be completely stretched out, and the black plastic sheet 41 will unfold to form a storage structure, thereby avoiding the situation where the bolt falls and directly hits the staff during the process of refitting or locking the nuts on the head iron bolts.

[0031] The lower side of the support bar 43 is a bent structure, and the side wall of the insulating rod 1 is slidably sleeved with a driving block 47. When the driving block 47 moves to a position against the surface of the limit block 44, the three support bars 43 will be fully opened, and the black plastic cloth 41 will unfold to form a storage structure. The side wall of the insulating rod 1 is fixedly connected with a positioning block 45, and the internal thread of the positioning block 45 is connected with a screw rod 46. The screw rod 46 and the internal rotation connection of the driving block 47 are fixedly installed with a rotating block 49 on the upper end of the screw rod 46. Rotating the rotating block 49 will drive the screw rod 46 to rotate, and the driving work of the driving block 47 on the insulating rod 1 can be realized at this time. The driving block 47 can realize the simultaneous opening of the three support bars 43 during the upward movement.

[0032] Reference Figure 1 and Figure 3 As shown, specifically, the adjustment structure 5 includes three limit frames 51 slidably connected to the inside of the bolt sleeve 2. The limit frames 51 are of a "U"-shaped structure. The limit frames 51 are slidably connected to the inside of the bolt sleeve 2. The bolt sleeve 2 is internally threaded with a screw rod 52, and the screw rod 52 is internally rotatably connected to the limit frames 51. When the screw rod 52 is rotated, the screw rod 52 will push the limit frames 51 to move.

[0033] The side wall of the limit frame 51 is provided with an inclined surface 53. The inclined surface 53 is provided to facilitate the insertion of the bolt or nut. The inner side of the bolt sleeve 2 is provided with three receiving grooves 54. The limit frame 51 can be retracted by rotating it back to the inner side of the receiving groove 54 to realize the retraction of the limit frame 51.

[0034] Working principle: when it is necessary to refit or lock the nut on the head iron bolt, first place the nut on the inner side of the bolt sleeve 2 and rotate the rotating block 49. The rotating block 49 will drive the screw rod 46 to rotate. At this time, the driving work of the driving block 47 on the insulating rod 1 can be realized. The driving block 47 can realize the simultaneous expansion of the three support bars 43 during the upward movement. When the driving block 47 moves to a position close to the surface of the limit block 44, the three support bars 43 will be completely expanded. At this time, the black plastic cloth 41 will unfold to form a storage structure, thereby avoiding the situation in which the bolt falls and directly injures the staff during the process of refitting or locking the nut on the head iron bolt. The fallen nut will fall into the inside of the expanded black plastic cloth 41, which is convenient for refitting or locking the nut. During the process, the nuts are collected. At the same time, the staff can observe the bolt position with the help of the black plastic sheet 41, which facilitates the installation of nuts on bolts under strong sunlight or rainy weather. By pushing the push rod 48, the nut located inside the bolt sleeve 2 can be pushed out after disassembly. The nut after being pushed out will fall into the black plastic sheet 41 for collection. The rotating block 49 is rotated in the opposite direction. When the driving block 47 moves out of the position abutting against the support bar 43, the black plastic sheet 41 will shrink due to the tension of the elastic rope 42, thereby realizing the collection of the collection structure 4. By setting the collection structure 4, the collection of nuts during the process of supplementing or locking the nuts on the bolts with the head iron is facilitated, the situation where the nuts hit the staff is avoided, and the safety of the use of the working tools is improved.

[0035] By rotating the screw rod 52, the screw rod 52 will push the limit frame 51 to move. At this time, the distance between the three limit frames 51 can be adjusted, which is convenient for the disassembly and assembly of nuts or bolts of different sizes. The inclined surface 53 is provided to facilitate the insertion of the bolts or nuts. The limit frame 51 is rotated and retracted to the inner side of the receiving groove 54, so that the limit frame 51 can be retracted. By providing the adjustment structure 5, the disassembly and assembly of bolts or nuts of different sizes are facilitated, and the use range of the working tool is further improved.
