Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-4, a positioning device for power engineering includes a mobile table 6, the number of the mobile table 6 is two, and the shape is a rectangle. One end of each of the mobile tables that are close to each other is connected by a connecting device 9, and the connecting device 9 includes a first connecting block 91, a second connecting block 92, a bolt 93, and a nut 94. The first connecting block 91 and the second connecting block 91 The two connecting blocks 92 are connected by bolts 93 and nuts 94 . The installation of the two mobile tables 6 is realized by the first connecting block 91 and the second connecting block 92 being close to each other.

The mobile table 6 is provided with a spirit level 2, the spirit level includes a casing 21 and a container 22, the container contains an air bubble, and the casing 21 is horizontally arranged on the lower side of the container 22. The current level is detected by the displacement of the bubble within the container 22 .

One end of the movable table 6 away from each other is provided with a movable bracket 1. The movable bracket 1 includes a knob 11, a screw 12, a nut 13, a bearing 14, and a base 15. The bottom end of the screw 12 is hinged with the base 15, and the screw 12 extends to move On the upper end of the table 6 , the screw 12 is threadedly connected with the nut 13 , the nut 13 and the movable table 6 are connected in rotation through the bearing 14 , and the knob 11 is connected on the outer surface of the nut 13 . By turning the knob 11 , the screw rod 12 can be driven to move up and down, so that one side of the mobile table 6 is tilted, so as to compensate for the ground with different heights. It is worth mentioning that since the adjustment is that the mobile table 6 will be inclined, the connection method of the nut 13 and the mobile table 6 can be the same as the connection method of the telescopic screw sleeve and the mobile table 6, as follows.

The upper surface of the mobile table 6 is provided with a connecting piece 4 , a threaded sleeve 5 is rotatably connected to the connecting piece 4 , and a telescopic screw 8 is threadedly connected to the threaded sleeve 5 .

The telescopic screw 8 is composed of three parts, the telescopic screw sleeve, the bearing seat and the screw rod, the inner ring of the bearing seat and the telescopic screw sleeve are in an interference fit, and the bearing seat is hinged with the mobile table 6, so that the telescopic screw sleeve can be realized with the mobile table 6. The rotational connection is in turn hinged to it. The telescopic screw sleeve is threadedly connected with the screw, the screw is hinged with the slider, the slider is slidably connected in the second chute, and the second chute is opened on the baffle 7 .

The telescopic screw 8 is slidably connected with a baffle plate 7 , the included angle between the baffle plate 7 and the surface of the mobile table 6 is 90°, and the second chute 71 adopts a rectangular structure. The movable table 6 is provided with a first chute 16 , and the lower end of the baffle is slidably connected in the first chute 16 .

The electric pole is hung on the ground.
