Description

Scheme for wired power transmission to mobile equipment in local area

Technical Field

The invention relates to a seventh scheme for wired power transmission to mobile equipment in a local area.

Background

My invention technology, a scheme for wired power transmission to local mobile equipment, can solve a part of problems of wired power transmission to the local mobile equipment. The disadvantages are that: due to the self-weight limitation of the spiral cable, the stretching ratio cannot be made large, so that the working area of the mobile equipment in a single local area is greatly limited.

The invention aims to provide a seventh scheme for transmitting power to the mobile equipment in the local area in a wired mode. So that the mobile device can use the power electricity as the energy source in a larger local area.

Disclosure of Invention

The invention is realized by the following steps: one column is fixed in the area where the mobile device is operating. A plurality of cable drag chains are vertically hinged with each other to form a cable drag chain group. One end of the connecting rod A is fixed with one end of the cable drag chain group, and the other end of the connecting rod A is horizontally hinged with a U-shaped component A. One end of the connecting rod B is fixed with the other end of the cable drag chain group. The other end is horizontally hinged with the U-shaped component B to form a set of bending arm components which can be horizontally bent and extended. The U-shaped member A is vertically hinged with the upper part of the upright post and can rotate around the upright post randomly and vertically. A screw hole is transversely processed on the lower side surface of the section of circular tube A and is welded below the U-shaped component B. The inner diameter and the outer diameter of a connecting pipe main body are the same as those of the round pipe A, a screw hole which is the same as that of the round pipe A is transversely processed on the upper side surface of the connecting pipe main body, and 2 circles of a plurality of screw holes are uniformly processed on the lower side surface of the connecting pipe main body according to the circumference. The upper surface of the connecting pipe is sealed and then is provided with a power socket. A base plate is secured to the mobile device by a plurality of bolts. A circular tube B is welded on the connecting pipe, the outer diameter of the circular tube B is slightly smaller than the inner diameter of the connecting pipe, and a groove is machined on the outer circle. After the connecting pipe is sleeved outside the round pipe B, a plurality of support bolts are screwed in from a circle of screw holes below the connecting pipe and inserted into the grooves in the outer circle of the round pipe B, so that the connecting pipe is locked in the vertical direction and can rotate vertically. The other group of a plurality of support head bolts are screwed into a circle of screw holes on the connecting pipe and fixed with the upper surface of a three-phase conductive slip ring A. The lower surface of the three-phase conductive slip ring A is fixed on the inner wall of the circular tube B. An upper head of the spring flexible shaft is sleeved with an upper round pipe A, and a lower head is sleeved with a connecting pipe. The two knobs are screwed into the screw holes in the side faces of the circular tube A and the connecting tube respectively, the spring flexible shaft is pressed, and the bending arm assembly is connected with the mobile equipment. When the mobile device moves, the bending arm assembly can be pulled to automatically follow the mobile device, and the mobile device bends or extends or rotates around the upright post. A three-phase conductive slip ring B is arranged between the upright post and the U-shaped component A. The lower outlet wire of the bending arm component is communicated with a power supply, and the upper extended power wire penetrates through the inner cavity of the bending arm component and is connected with a waterproof power socket which can be plugged and electrified with a power plug fixed on the connecting pipe. An outgoing line on the three-phase conductive slip ring A is connected with a power plug, and an outgoing line on the lower side of the three-phase conductive slip ring A leads to the inside of the mobile equipment. Since the weight of the power cord is mainly borne by the bending arm assembly, the cable drag chain assembly can be connected in a plurality of sections and is long after being stretched, and the bending arm assembly can vertically rotate around the upright post, the working area of a single local area can be larger.

By adopting the technical scheme of the invention, the mobile equipment can use the power electricity as the energy source in a larger local area, and the mobile equipment is particularly suitable for engineering machinery which needs to frequently move a working local area.

The U-shaped component A3 is vertically hinged above the upright post 2 and can rotate vertically around the upright post 2. A screw hole is transversely processed on the lower side surface of the circular tube A10-1 and is welded below the U-shaped component B10. The main body of the connecting pipe 14 has the same inner and outer diameters as the round pipe A10-1, the upper side surface of the connecting pipe is also transversely provided with a screw hole which is the same as the side surface of the round pipe A10-1, and the lower side surface of the connecting pipe is uniformly provided with a plurality of screw holes of 2 circles at the upper part and the lower part according to the circumference. The connecting pipe 14 is sealed and provided with a power socket 13. The base plate 18 is fixed to the mobile device 20 by 4 bolts 19. A round tube B17 is welded on the upper surface of the connecting pipe, the outer diameter of the round tube B is slightly smaller than the inner diameter of the connecting pipe 14, and a groove is processed on the outer circle of the round tube B. The connecting pipe 14 is sleeved outside the round pipe B17, and a plurality of supporting bolts 16 are screwed in from a screw hole of a circle below the connecting pipe 14 and inserted into a groove on the excircle of the round pipe B17 to lock the connecting pipe 14 in the vertical direction but can rotate vertically. The other group of a plurality of supporting head bolts 16 are screwed into a circle of screw holes on the upper surface of the connecting pipe 14 and fixed with the upper surface of a three-phase conductive slip ring A15, and the lower surface of the three-phase conductive slip ring is fixed on the inner wall of a circular pipe B17.
