Description

Product for wired power transmission to local mobile equipment

Technical Field

The utility model relates to a product for wired power transmission to local mobile equipment.

Background

Current mobile equipment, such as forklifts, forklift trucks, shovels and various agricultural machinery, use most of their energy sources in gasoline and diesel. The defects are that: the air is polluted, the use cost is high, and the gasoline and the diesel are valuable non-renewable strategic materials.

Although some newly developed mobile devices are powered by batteries, pollution can be reduced, and use cost is reduced, a group of power batteries are low in cost, so that production cost of the mobile devices is increased. And the service life of the power battery is limited, so that the total cost performance of the mobile equipment is not ideal.

The utility model discloses a scheme for transmitting power to local mobile equipment in a wired mode, which can solve the problem that a part of the power is transmitted to the local mobile equipment in a wired mode. The defects are that: the stretching ratio cannot be made large due to the limitation of the dead weight of the spiral cable, so that the working area of the mobile equipment in a single local area is limited greatly.

The utility model aims to provide another product technical scheme for wired power transmission to local mobile equipment. So that the mobile device can use the power electricity as the energy source in a larger area.

Disclosure of Invention

A linear bearing is respectively arranged at four corners of one sliding block and sleeved on two cables, and the sliding block can slide horizontally along the cables. One end of a sliding rod is welded with a check ring, the other end of the sliding rod is horizontally hinged with a U-shaped component A, an inner hole of a linear bearing B is sleeved on the sliding rod, and an outer ring of the linear bearing B is horizontally hinged with the U-shaped component B to form a sliding rod assembly which can horizontally slide. The U-shaped component A is vertically hinged with the lower part of the center of the sliding block and can vertically rotate around the sliding block. A pair of screw holes are transversely machined below a section of rectangular pipe and welded below the U-shaped component B. The outer diameter of a connecting pipe main body is slightly smaller than the opposite side size of the inner wall of the rectangular pipe, a pair of light holes slightly larger than the screw holes on the rectangular pipe are transversely processed on the upper surface of the connecting pipe main body, and 2 circles of screw holes are uniformly distributed on the lower 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 bottom plate is fixed with the mobile device through a plurality of bolts, a round tube B is welded on the bottom plate, the outer diameter of the round tube B is slightly smaller than the inner diameter of the connecting tube, and a groove is formed in the outer circle of the connecting tube. After the connecting pipe is sleeved outside the circular pipe B, a plurality of branch head bolts are screwed in from a circle of screw holes below the connecting pipe and inserted into grooves on the outer circle of the circular pipe B, so that the connecting pipe is locked in the up-down direction, but can vertically rotate. The other group of a plurality of supporting head bolts are screwed into a circle of screw holes on the connecting pipe and are 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. After the connecting pipe is sleeved on the rectangular pipe, the two knobs are screwed into screw holes on two sides of the rectangular pipe respectively, and then penetrate through the unthreaded holes on the connecting pipe to connect the sliding rod assembly with the mobile equipment. The sliding rod assembly can be pulled to automatically follow the mobile equipment to slide or rotate around the upright post when the mobile equipment moves. The upper surface of the three-phase conductive slip ring B is fixed with the central inner wall of the sliding block, and the lower surface of the three-phase conductive slip ring B is fixed with the center of the U-shaped component A. The power line is connected to the upper surface of the three-phase conductive slip ring B along the upright post, the middle horizontal part is wound into a spiral shape, and the power line is hung on the cable through a plurality of hanging rings. The power line extending out from the lower surface of the three-phase conductive slip ring B is spirally wound outside the sliding rod 8 and then penetrates through the central hole of the U-shaped component B to be connected with a waterproof power socket, and can be plugged and electrified with the power plug fixed on the connecting pipe. The outgoing line on the upper side of the three-phase conductive slip ring A is connected with a power plug, and the outgoing line on the lower side is led into the mobile equipment. Since the weight of the power cord is mainly borne by the cable and the sliding rod assembly, and the length of the cable and the sliding rod can be made long by connection, and the sliding rod assembly can vertically rotate around the sliding block, the working area of a single local area can be larger.

The product of the utility model can make the mobile equipment use power electricity as energy in a larger area, and is particularly suitable for agricultural machinery with larger working area.

Four corners of the sliding block 5 are respectively provided with a linear bearing 5-1 which is sleeved on the two cables 2 and can slide horizontally along the cables 2. One end of the sliding rod 8 is welded with a retainer ring 8-1 to prevent the sliding rod 8 from sliding out of the linear bearing B10. The other end is horizontally hinged with the U-shaped component A6. The linear bearing B10 is sleeved on the sliding rod 8, and the outer ring is horizontally hinged with a U-shaped member B (the linear bearing B10 and the power line 4 are not shown in a sectional state in the drawing for the sake of showing the structure of the same). They constitute a set of sliding rod assembly which can vertically rotate around the sliding block 5 by vertically hinging the U-shaped component A6 with the lower part of the center of the sliding block 5. A pair of screw holes are transversely formed below the rectangular tube 9-1 and welded below the U-shaped member B9. The outer diameter of the connecting pipe 13 is slightly smaller than the opposite side of the inner wall of the rectangular pipe 9-1, a pair of light holes slightly larger than the screw holes on the rectangular pipe 9-1 are transversely processed on the upper surface, and a plurality of screw holes of 2 circles are uniformly processed on the lower surface according to the circumference. The upper surface of the connection pipe 13 is sealed and then is provided with a power plug 12. The base plate 18 is fixed to the mobile device 20 by four bolts 19. The round tube B17 is welded on the connecting tube, the outer diameter of the round tube B is slightly smaller than the inner diameter of the connecting tube 13, and a groove is formed in the outer circle of the round tube B. The connecting pipe 13 is sleeved outside the circular pipe B17, a plurality of branch head bolts 16 are screwed in from a circle of screw holes below the connecting pipe 13 and inserted into grooves on the outer circle of the circular pipe B17 to lock the connecting pipe 13 in the up-down direction, but can vertically rotate. The other group of a plurality of branch bolts 16 are screwed into a circle of screw holes on the round connecting pipe 13, are fixed with the upper surface of the three-phase conductive slip ring A15, and the lower surface of the branch bolts is fixed on the inner wall of the round pipe B17. After the rectangular tube 9-1 is sleeved with the connecting tube 13, the two knobs 14 are screwed into screw holes on two sides of the rectangular tube 9-1 respectively, and then penetrate through the unthreaded holes on the connecting tube 13 to connect the sliding rod assembly with the mobile device 20. The mobile device 20 may be pulled to automatically follow it or slide or rotate about the slide 5 as it moves. The upper surface of the three-phase conductive slip ring B7 is fixed with the central inner wall of the sliding block 5, and the lower surface is fixed with the center of the U-shaped component A6. The power line 4 is connected to the upper surface of the three-phase conductive slip ring B7 along the upright post 1, the middle horizontal part is wound into a spiral shape, and is hung on the cable 2 through a plurality of hanging rings 3 to extend or retract along with the sliding block 5. The power line 4 extending out from the lower surface of the three-phase conductive slip ring B7 is spirally wound outside the sliding rod 8, then penetrates through the central hole of the U-shaped member B9, is connected with the waterproof power socket 11, and can be plugged with the power plug 12 fixed on the connecting pipe 13 to be electrified.

With such a structure, the mobile device 20 is ensured not to be rotated or moved, the power cord 4 is not wound, and the power transmission is safe and reliable. Since the weight of the power cord 4 is mainly borne by the cable 2 and the sliding bar assembly, the length of the cable 2 is increased by increasing the distance between the two uprights 1, the sliding bar 8 can be also connected to be long, and the sliding bar assembly can vertically rotate around the sliding block 5, so that the working area of the single local area 21 can be larger. The linear bearing B10 may be a rolling bearing or a sliding bearing, which is a common technique. The slide rod 8 is generally manufactured in a circular tube so that the linear bearing B10 can be manufactured in a general-purpose product. Of course, other cross-sectional shapes of tubing may be used.
