Description

Product for wired power transmission of mobile equipment in local area

Technical Field

The invention relates to a product for transmitting power to a local mobile device in a wired mode.

Background

At present, most of mobile equipment such as forklifts, excavators and various agricultural machines use gasoline and diesel oil as energy sources. The disadvantages are that: the air is polluted, the use cost is high, and gasoline and diesel oil are non-renewable valuable strategic materials and can be easily pinched by enemies in a very period.

Although some newly developed mobile devices are powered by batteries, which can reduce pollution and use cost, a group of power batteries has low cost, so that the production cost of the mobile devices is increased. The total cost performance of the mobile equipment is not ideal due to the service life limitation of the power battery.

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 rate 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 another technical scheme of a product for wired power transmission to mobile equipment in a local area. 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. One end of a sliding rod is inserted into a linear bearing, and the linear bearing is horizontally hinged with a U-shaped component A. The other end is horizontally hinged with the U-shaped component B to form a set of sliding rod assembly which can horizontally slide. The U-shaped member A is vertically hinged above the upright post and can vertically rotate around the upright post. And a pair of screw holes are transversely processed below one section of rectangular pipe and welded below the U-shaped component B. The outer diameter of a connecting circular tube main body is slightly smaller than the opposite side of the inner wall of the rectangular tube, a pair of unthreaded holes slightly larger than the screw holes on the rectangular tube are transversely processed on the connecting circular tube main body, and 2 circles of a plurality of screw holes are uniformly processed on the lower surface of the connecting circular tube main body according to the circumference. The upper surface of the connecting circular tube 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 pipe B is welded on the bottom plate, the outer diameter of the round pipe B is slightly smaller than the inner diameter of the connecting round pipe, and a groove is machined in the outer circle. After the connecting circular tube is sleeved outside the circular tube B, a plurality of support head bolts are screwed in from a circle of screw holes below the connecting circular tube and inserted into the grooves in the outer circle of the circular tube B, so that the connecting circular tube 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. After the rectangular pipe sleeve is connected with the circular pipe, the two knobs are screwed into the 2 screw holes in the rectangular pipe respectively, then the knobs penetrate through the unthreaded holes in the connected circular pipe, and the sliding rod assembly is connected with the mobile equipment. When the mobile device moves, the sliding rod assembly can be pulled to automatically follow the mobile device to slide or rotate 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 U-shaped member is communicated with a power supply, the upper extended power wire is spirally wound outside the sliding rod and then passes through the inner cavity of the U-shaped member B to be connected with a waterproof power socket, and the waterproof power socket can be plugged and electrified with a power plug fixed on the connecting circular tube. 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 sliding bar assembly, which can be made long and vertically rotatable about the upright, the working area of a single 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 is particularly suitable for engineering machinery and agricultural machinery which need to move working local areas frequently.

Detailed Description

The present invention will be described in further detail with reference to examples.

Referring to figures 1 and 2: the upright post 2 is welded on a post plate 2-2, and four groups of wheels 2-1 are arranged below the post plate 2-2. A plurality of balance weights 1 are pressed on the column plates 2-2 to fix the upright column 2 in the working area 19. The column 2 can also move when the counterweight iron 1 is removed. One end of the slide bar 3 is inserted into a linear bearing 6, and the linear bearing 6 is horizontally hinged with a U-shaped member A4. (the linear bearings 6 in the drawings are not shown in section for clarity of their construction). The other end is horizontally hinged with the U-shaped component B9 to form a set of sliding rod assembly which can horizontally slide. One end of the sliding rod 3 is welded with a retainer ring 3-1 to prevent the sliding rod 3 from sliding out of the linear bearing 6. The linear bearing 6 can adopt a rolling bearing and can also adopt a sliding bearing, and the common technology is adopted. The slide rod 3 is generally manufactured by a circular tube so that the linear bearing can be a general-purpose product. Of course, other cross-sectional shapes of tubing may be used. The U-shaped component A4 is vertically hinged above the upright post 2 and can vertically rotate around the upright post 2. A pair of screw holes are transversely processed below the rectangular pipe 9-1 and are welded below the U-shaped component B9. The outer diameter of the main body of the connecting circular tube 12 is slightly smaller than the opposite side size of the inner wall of the rectangular tube 9-1, a pair of unthreaded holes slightly larger than the screw holes on the rectangular tube 9-1 are transversely processed on the main body, 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 connecting circular tube 12 is sealed and then is provided with a power plug 11. The base plate 17 is fixed to the moving device 18 by 4 bolts 16. A circular tube B15 is welded on the upper surface of the connecting circular tube, the outer diameter of the connecting circular tube is slightly smaller than the inner diameter of the connecting circular tube 12, and a groove is processed on the outer circle. The connecting circular tube 12 is sleeved outside the circular tube B15, and the plurality of support bolts 14 are screwed in from a circle of screw holes below the connecting circular tube 12 and inserted into the grooves on the outer circle of the circular tube B15 to lock the connecting circular tube 12 in the vertical direction, but can rotate vertically. The other group of a plurality of branch head bolts 14 are screwed into a circle of screw holes on the round tube 12 and fixed with the upper part of the three-phase conductive slip ring A13, and the lower part of the three-phase conductive slip ring A is fixed on the inner wall of the round tube B15. After the rectangular tube 9-1 is sleeved with the connecting circular tube 12, the two knobs 8 are respectively screwed into screw holes on two surfaces of the rectangular tube 9-1 and then penetrate through unthreaded holes on the connecting circular tube 12 to connect the sliding rod assembly with the mobile equipment 18. The movement device 18, when moved, may drag the sliding bar assembly to automatically follow it, either sliding or rotating about the upright. And a three-phase conductive slip ring B5 is arranged between the stand column and the U-shaped component A4. The lower outlet of the water-proof power socket is communicated with a power supply (not shown in the figure), the upper extended power cord 7 is spirally wound outside the sliding rod 3 and then passes through the inner cavity of the U-shaped component B9 to be connected with a water-proof power socket 10, and the water-proof power socket can be plugged and electrified with a power plug 11 fixed on a connecting circular tube 12. The upper outgoing line of the three-phase conductive slip ring A13 is connected with the power plug 11, and the lower outgoing line leads to the inside of the mobile device 18. With such a structure, the power cord 7 is prevented from being wound and the power transmission is safe and reliable no matter how the mobile device 18 rotates or moves. Since the weight of the power supply line 7 is mainly borne by the sliding bar assembly, the sliding bar 3 can be made long and the sliding bar assembly can be vertically rotated around the upright 2, the working area of the single area 19 can be larger. The structure of the three-phase conductive slip ring a 13 and the three-phase conductive slip ring B5 and the mounting structure between the U-shaped member A4 and the vertical column are common technologies, and will not be described in detail here.

Referring to FIG. 3: this is an example in an agricultural field, with the post B20 fixed in the work area 19. The moving device B21 in the figure is an agricultural machine. Because the vertical projection of the working area of the sliding rod assembly is a circle, after the two sets of assemblies are installed in the area in a crossed manner, as long as part of the two circles are overlapped, the mobile equipment B21 can move to the projection overlapping area after completing the work in the working area of one set of assemblies, the two knobs 8 are screwed out, the rectangular pipe 9-1 is moved upwards to be separated from the connecting circular pipe 12, and then the waterproof power socket 10 is pulled out from the power plug 11 to push away the original sliding rod assembly. The sliding rod assembly in the new working area is pulled over, the waterproof power socket 10 of the sliding rod assembly is inserted into the power plug 11 on the mobile device B21, the rectangular pipe 9-1 on the sliding rod assembly in the new working area is moved downwards, the connecting circular pipe 12 is sleeved on the sliding rod assembly, and the two knobs 8 are screwed to perform work in the new working area.

The mobile device using the energy conduction scheme can be hauled by other common vehicles from the storeroom to the working area. It is of course also possible to mount a small power battery on the mobile device for short-distance movement. The common technology can solve the problem.

In this embodiment, the column B20 is fixed to the ground in the work area using a reinforced concrete round bar. The slide bar 3 is a 100 × 5 circular tube. The remaining general components, processes, structures are conventional and common technology and will not be described in detail herein.
