Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Example 1:

referring to fig. 2, the embodiment discloses a lifting device for a copper bar 22 without a cross arm, which includes a copper bar 22, an electrode and a driving device, which are fixedly connected. The electrode is specifically a carbon electrode. The copper bar 22 is connected to a power supply module, not shown in the drawings, by a wire 29.

The driving device comprises a connecting component and a driver which are arranged in an insulating mode. The connecting assembly is connected with the copper bar 22 and the driver; the driver is used for driving the copper bar 22 to move up and down through the connecting assembly, and the driver is not shown in the drawing.

The connection assembly includes a flexible cord 24 and an insulator 25. The flexible cord 24 is embodied as a steel cord, whereas the insulator 25 is preferably an insulator. One end of the insulator is hinged with the copper bar 22, and the other end of the insulator is fixedly connected with the flexible rope 24. The other end of the flexible cord 24 is connected to the driver. The driver preferably adopts the scheme that a speed reducing motor 21 is combined with a wheel disc, and a flexible rope 24 is fixedly connected with the wheel disc. The reduction motor 21 drives the wheel disc to rotate, and then the flexible rope 24 is wound on the wheel disc, so that the copper bar 22 is driven to move up and down. The number of the connecting components can be adjusted adaptively according to the weight of the copper bar 22. However, the reduction motor 21 may be replaced with a combination of the motor 21 and a reduction gear.

Alternatively, the driving device may also use a combination of a chain, a sprocket, an insulator, and a driver. The two ends of the insulator are respectively connected with a chain and a copper bar 22, the other end of the chain is connected with a chain wheel, and the chain wheel is driven by a driver to rotate so as to wind the chain.

Compared with the prior art, the improvement of the embodiment is mainly realized by that the insulating plate 26 and the guiding device are also included in the embodiment. The guide mechanism serves to restrict the moving direction of the copper bar 22 to a vertical direction, and the insulating plate 26 is provided between the guide and the copper bar 22 for insulation.

The guide means comprise a guide post 23, a bracket 27 and a plurality of guide wheels 28 mounted on the bracket 27. The bracket 27 is provided with clamping grooves in the horizontal front, back, left and right directions of the copper bar 22, and the copper bar 22 is clamped in the clamping grooves. The insulating plate 26 is provided at a contact portion of the copper bar 22 and the bracket 27 for insulation. The insulating plate 26 may be a mica plate or an bakelite plate. The guide wheel 28 is used for rolling on the orientation post 23; the guide wheels 28 are distributed on different sides of the orientation post 23 to constrain the direction of movement of the copper bar 22 to a vertical direction. The body of the guide wheel 28 is made of insulating material. In the present embodiment, the orientation column 23 preferably adopts a rectangular square tube structure, and the guide wheels 28 are distributed on four planes of the side wall of the orientation column 23. When the driving device drives the copper bar 22 to move up and down, the copper bar 22 moves up and down together with the insulating plate 26, the bracket 27 and the guide wheel 28, and the interaction between the guide wheel 28 and the orientation column 23 restricts the moving direction of the copper bar 22 to be a vertical direction.
