[0028] 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 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.

[0029] The utility model embodiment provides a device for shortening the working time of replacing overhead ground wire clamps on concrete poles of power transmission lines, comprising: a wing-shaped frame 10; see Figure 1 and Figure 2 , Figure 1 This is a front structural schematic diagram of a device for shortening the working time of replacing overhead ground wire clamps on concrete poles of power transmission lines according to a preferred embodiment of the utility model. Figure 2The back structure diagram of the device for shortening the working time of replacing the overhead ground wire clamp of the concrete pole of the power transmission line according to a preferred embodiment of the utility model. The wing-shaped frame 10 comprises: a crossbeam (not shown in the figure), a first retractable mechanism 107 and a second retractable mechanism 108 symmetrically arranged on both sides of the crossbeam, and a first bolt assembly 104 connected to the first retractable mechanism 107 and a second bolt assembly 105 connected to the second retractable mechanism 108; a groove 101 for accommodating the overhead ground wire clamp is arranged on the crossbeam of the wing-shaped frame 10, see Figure 4 , Figure 4 It is a partial enlarged bottom view of a groove in a device for shortening the working time of replacing an overhead ground wire clamp on a concrete pole of a transmission line according to a preferred embodiment of the utility model. The top of the two side walls of the groove 101 are provided with a first clamping end 102 and a second clamping end 103 for clamping the overhead ground wire clamp. It should be noted that the thickness of the first clamping end 102 and the second clamping end 103 is greater than the thickness of the two side walls of the groove 10, in order to improve the lateral stress bearing capacity of the wing-shaped frame 10 and avoid being bent and unable to clamp the overhead ground wire clamp.

[0030] In the present application, the first telescopic mechanism 107 and the second telescopic mechanism 108 cooperate to adjust the width of the wing-shaped frame 10 to adapt to concrete poles of different diameters. When specifically adapting to different concrete poles, it can be achieved by the first telescopic mechanism 107 and the second telescopic mechanism 108. The first telescopic mechanism 107 and the second telescopic mechanism 108 are also symmetrically provided with a plurality of fixing holes 106, and the fixing holes 106 are used to fix the wing-shaped frame 10 on the concrete pole through nuts.

[0031] In specific implementation, according to the different diameters of the concrete rods, the first retractable mechanism 107 and the second retractable mechanism 108 can adjust the width of the wing-shaped frame 10 by adjusting the corresponding positions of the fixing holes 106. For details, see Figure 3a , Figure 3b , Figure 3c For example, for a concrete pole with a relatively large diameter, the states of the first telescopic mechanism 107 and the second telescopic mechanism 108 can be set to Figure 3a For a relatively small diameter concrete rod, the state of the first retractable mechanism 107 and the second retractable mechanism 108 can be set to Figure 3c Of course, according to the actual diameter of the concrete rod state, the state of the first retractable mechanism 107 and the second retractable mechanism 108 can also be set to Figure 3b It should be noted that the state change of the first telescopic mechanism 107 and the second telescopic mechanism 108 can be realized by a sliding telescopic member. For example, one of the two is used as a slider and the other is used as a slide groove.

[0032] It should be noted that when the wing-shaped frame 10 is fixed on the concrete pole, the steel bar can be wrapped around the concrete pole and then passed through the fixing hole 106 for fixing. After the fixing hole 106 is aligned, it is fixed by a nut. In addition, by providing the first telescopic mechanism 107 and the second telescopic mechanism 108, the wing-shaped frame 10 can be adapted to concrete poles of different sizes, thereby expanding the scope of use of the wing-shaped frame 10.

[0033] In the present application, the first bolt assembly 104 and the second bolt assembly 105 are symmetrically arranged on both sides of the wing-shaped frame 10, and the first bolt assembly 104 and the second bolt assembly 105 are used to connect the transmission line; the groove 101 cooperates with the first bolt assembly 104 and the second bolt assembly 105 to adjust the distance between the overhead ground wire clamp and the top of the concrete pole. It should be noted that the reason why the present application sets up a lifting tool that can adjust the distance between the overhead ground wire clamp and the top of the concrete pole is mainly because when the staff of the power transmission operation and inspection center replace the overhead ground wire clamp, the ground wire clamp is at a small distance from the top of the pole, and there is no suitable lifting tool bearing point, resulting in a long average time for replacing a single overhead ground wire clamp, which affects the efficiency of maintenance and troubleshooting. Based on this, the wing-shaped frame 10 described in the present application can adjust the distance between the overhead ground wire clamp and the top of the concrete pole, shortening the time for replacing the overhead ground wire clamp on the concrete pole of the transmission line, and improving the maintenance efficiency.

[0034] Among them, the first bolt assembly 104 includes: a first nut 104-1, a first threaded column 104-2 matched with the first nut 104-1, a first buckle 104-3 and a first wrench 104-4 located on the first threaded column 104-2; the second bolt assembly 105 includes: a second nut 105-1, a second threaded column 105-2 matched with the second nut 105-1, a second buckle 105-3 and a second wrench 105-4 located on the second threaded column 105-2.

[0035] Specifically, the first nut 104-1 and the second nut 105-1 are connected to the crossbeam; the first clip 104-3 is located at the bottom of the first threaded column 104-2, and the second clip 105-3 is located at the bottom of the second threaded column 105-2. The first clip 104-3 and the second clip 105-3 are used to fix the wing-shaped frame 10 on the transmission line, wherein the first clip 104-3 and the second clip 105-3 each include a U-shaped part and a fixing bolt. When the first clip 104-3 and the second clip 105-3 are used to fix the wing-shaped frame 10 on the transmission line, the fixing bolt is first removed, the transmission line is placed in the U-shaped part, and then the fixing bolt is used to fix the transmission line in the U-shaped part.

[0036] In the present application, the first wrench 104-4 includes a first handle 104-4-1 and a first spiral hole 104-4-2, and the first spiral hole 104-4-2 is sleeved on the first spiral column 104-2; the inner side of the first spiral hole 104-4-2 is provided with a thread matching the first threaded column 104-2, and by rotating the first handle 104-4-1, the height of the first bolt assembly 104 is controlled to adapt to the installation position of the overhead ground wire clamp; the second wrench 105-4 includes a second handle 105-4-1 and a second spiral hole 105-4-2, and the second spiral hole 105-4-2 is sleeved on the second spiral column 105-2; the inner side of the second spiral hole 105-4-2 is provided with a thread matching the second threaded column 105-2, and by rotating the second handle 105-4-1, the height of the second bolt assembly 105 is controlled to adapt to the installation position of the overhead ground wire clamp.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
