detailed description

The implementation of the present utility model is illustrated by specific specific examples below, and those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

As shown in Figure 1, a lifting device for electric equipment includes a beam 2 and a suspension rope 3 suspended on the beam 2, and includes two lifting frames on the left and right sides; The transmission box 102 of the transmission box 102, the optical axis section of the bottom end of the screw rod 103 that is vertically arranged extends into the transmission box, and the bottom end of the base 101 is fixed with a channel-shaped claw 116, and the opening of the claw 116 can be covered on the pole. Bear (shown in dotted line among the figure), and adopt the bolt 117 that runs through the opening two sides walls of claw hand 116 to fix claw hand 116 on the cross arm. The bottom end of the optical axis section is provided with a driven bevel gear 104, and the driven bevel gear 104 meshes with the first driving bevel gear 106 fixed on the main shaft of the motor 105; There is a Γ-shaped support 107, the vertical part of the support 107 stands on the transmission case 102, the horizontal part is embedded with a bearing 108, and the smooth section at the top of the screw 103 is located in the bearing 108; a nut 109 on the screw 103 One side is provided with slide block 110, and the other side is connected with an end of crossbeam 2, and described slide block 110 can vertically slide in the chute on the vertical part of support 107, so that when two motors 105 rotate simultaneously The connected beams 2 can vertically reciprocate. In order to facilitate the movement, the bottom end of the lifting tool is also equipped with lockable universal casters.
