Specific implementation manner

[0019] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1

[0021] As Figures 1 to 3 shown, a clamping device for cutting electric power pipelines. This clamping device is used to replace traditional manual clamping and limiting of electric power pipelines for easy cutting. Structurally, this clamping device includes a stable base 1 with a through-channel opening for the passage of electric power pipelines. One side end of the channel opening is provided with a movable clamping mechanism for clamping and limiting the electric power pipelines. At the same time, this movable clamping mechanism includes a concentrically arranged movable rotating disc 2. The movable rotating disc 2 is coaxially arranged with the channel opening and is rotationally connected to the base 1. On the movable rotating disc 2, there are movably arranged a first limiting rod 3, a second limiting rod 4, and a third limiting rod 5. Driven by the movement of the movable rotating disc 2, the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 are used to clamp and limit the electric power pipelines passing through the channel opening and the movable rotating disc 2 for easy cutting.

[0022] Embodiment 2

[0023] In an embodiment, a limiting disk 21 is provided at one side end of the movable rotating disk 2 away from the base 1, and the limiting disk 21 is connected to the movable rotating disk 2 through a connecting block; specifically, the movable rotating disk 2 is connected to the base 1 through a bearing for rotation. In this way, the movable rotating disk 2 is rotationally connected to the base 1. And in the embodiment, a rotating movable seat 22 is hinged on the movable rotating disk 21. A lead screw 23 is movably disposed through the rotating movable seat 22. One end of the lead screw 23 away from the rotating movable seat 22 can pass through the fixed seat 24 through a bearing for rotation. One end of the lead screw 23 away from the rotating movable seat 22 is connected to a lead screw machine for driving the lead screw 23 to move. The lead screw machine is fixedly installed on the base 1; the fixed seat 24 is connected to the base 1. It should be noted that since the lead screw machine is a prior art, the lead screw machine is not shown and labeled in the drawings. By controlling the lead screw machine to drive the lead screw 23 to rotate, the lead screw 23 rotates through the fixed seat 24 and the lead screw 23 "moves" through the rotating movable seat 22. The rotation of the lead screw 23 drives the rotating movable seat 22 to "move". The rotating movable seat 22 drives the movable rotating disk 2 "hinged thereto" to rotate around the channel opening provided on the base 1. Thus, the movable rotating disk 2 drives the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 movably connected to the movable rotating disk 2 to move. Finally, the relative movement of the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 can be realized to limit and clamp the power pipeline passing through the movable rotating disk 2. It should be noted here that the channel opening, the movable rotating disk 2, and the limiting disk 21 are all coaxially arranged to facilitate the passage of the power pipeline therethrough.

[0024] Embodiment 3

[0025] The first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 of this setting are all movably arranged with the movable rotating disc 2 respectively, that is, the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 can be driven by the movable rotating disc 2 to move, so as to limit and clamp and "release" the power pipeline passing through the movable rotating disc 2. In the embodiment, the first limiting rod 3 of this setting is rotatably connected to one end of the first movable rod 31 through a rotating shaft, and a first limiting seat 32 is rotatably connected between the limiting disc 21 and the movable rotating disc 2 through a rotating shaft. The end of the first movable rod 31 away from the first limiting rod 3 movably passes through the first limiting seat 32, and the end of the first movable rod 31 away from the first limiting rod 3 is rotatably connected to the side wall of the base 1 through a pin shaft. Since the connection structures of the second limiting rod 4 and the third limiting rod 5 with the first limiting rod 3 are similar; therefore, the second limiting rod 4 is rotatably connected to one end of the second movable rod 41 through a rotating shaft, and a second limiting seat 42 is rotatably connected between the limiting disc 21 and the movable rotating disc 2 through a rotating shaft. The end of the second movable rod 41 away from the second limiting rod 4 movably passes through the second limiting seat 42, and the end of the second movable rod 41 away from the second limiting rod 4 is rotatably connected to the side wall of the base 1 through a pin shaft; and, the third limiting rod 5 is rotatably connected to one end of the third movable rod 5 through a rotating shaft, and a third limiting seat 52 is rotatably connected between the limiting disc 21 and the movable rotating disc 2 through a rotating shaft. The end of the third movable rod 51 away from the third limiting rod 5 movably passes through the third limiting seat 52, and the end of the third movable rod 51 away from the third limiting rod 5 is rotatably connected to the side wall of the base 1 through a pin shaft. During design, the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 are evenly arranged at the channel openings formed in the movable rotating disc 2, and the included angle between each limiting rod is 120°. And the first movable rod 31 for connecting the first limiting rod 3, the second movable rod 41 for connecting the second limiting rod 4, and the third movable rod 51 for connecting the third limiting rod 5 are evenly connected to the side wall of the base 1 and the included angles between any two of them are all 120°. In this way, the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 are arranged as movable "claws" at the channel openings formed in the set movable rotating disc 2. When the screw machine drives the movable rotating disc 2 to rotate through the screw rod 23, the movable rotating disc 2 drives the first movable rod 31, the second movable rod 41, and the third movable rod 51 to perform "circular movement" under the action of their respective movable limiting seats respectively. Finally, the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5 are respectively driven to clamp the power pipeline passing between the three of them. After cutting is completed, the rotation of the movable rotating disc 2 is controlled in the reverse direction, and through the movement of the first limiting rod 3, the second limiting rod 4, and the third limiting rod 5, the power pipeline clamped and limited is finally released. From the structure of this clamping device, this clamping device can not only replace manual labor to clamp and limit the power pipeline, but also has a simple structure and convenient operation, and can improve the cutting efficiency of the power pipeline.
