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 area 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 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 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. The telescopic rods with the section sizes gradually increased are mutually sleeved. One end of the tail section telescopic rod is horizontally hinged with a U-shaped component A. One end of the head section telescopic rod is horizontally hinged with the U-shaped component B to form a set of telescopic rod assembly which can horizontally stretch. 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 circular tube B is welded on the bottom plate, the outer diameter of the circular tube B is slightly smaller than the inner diameter of the connecting circular tube, 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 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 screw holes in the rectangular pipe respectively and then penetrate through the unthreaded holes in the connecting circular pipe to connect the telescopic rod assembly with the mobile equipment. When the mobile equipment moves, the telescopic rod component can be pulled to automatically follow the mobile equipment, and the mobile equipment can extend or retract 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 power socket is connected to a power supply, and the upper extending power line passes through the telescopic rod component and the cavity of the U-shaped component B to be connected with a waterproof power socket and can be spliced and electrified with a power plug fixed on the connecting circular tube. The part of the power cord in the telescopic rod component is processed into a spiral shape. 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 is communicated with the inside of the mobile equipment. Because the weight of the power cord is mainly born by the telescopic rod assembly, the telescopic rod can be connected into a plurality of sections and is long after being extended, and the telescopic rod assembly can vertically rotate around the upright post, the working area of a single local area can be larger.

The product of the invention can enable the mobile equipment to use the power electricity as the energy source in a larger local area, and is particularly suitable for engineering machinery which needs to move a working local area 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 the post plate 2-2, and four groups of wheels 2-1 are arranged under 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 weight iron 1 is removed, and the column 2 can also move. A plurality of sections of first-section telescopic rods 5-4, second-section telescopic rods 5-3, three-section telescopic rods 5-2 and last-section telescopic rods 5-1 with gradually increased cross-sectional sizes are mutually sleeved, linear bearings 7 are arranged between adjacent telescopic rods, and the linear bearings 7 can adopt rolling bearings or sliding bearings, and the common technology. One end of the tail section telescopic rod 5-1 is horizontally hinged with a U-shaped component A4. One end of the head section telescopic rod 5-4 is horizontally hinged with the U-shaped component B9 to form a set of telescopic rod assembly which can horizontally stretch. The telescopic rod is generally processed by a round tube, so that the linear bearing can be a universal product. Of course, other cross-sectional shapes of tubing may be used. The U-shaped member 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 16 is fixed to the moving device 18 by 4 bolts 17. A circular tube B15 is welded on the upper surface of the connecting circular tube, the outer diameter of the circular tube B 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 a plurality of supporting bolts 14 are screwed in from a screw hole of one circle below the connecting circular tube 12 and inserted into a groove on the excircle 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 upper surface of the round tube 12 and fixed with the upper surface of a three-phase conductive slip ring A13, and the lower surface of the three-phase conductive slip ring A is fixed on the inner wall of a 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 telescopic rod assembly with the mobile equipment 18. When the moving device 18 moves, the telescopic rod assembly can be dragged to automatically follow the moving device, and the telescopic rod assembly can extend or retract or rotate around the upright post. A three-phase conductive slip ring B6 is mounted between the mast 2 and the U-shaped member A4. The lower outlet of the power supply is communicated with a power supply (not shown in the figure), and the power supply wire 3 extending out of the upper part passes through the telescopic rod component and the inner cavity of the U-shaped component B9 to be connected with a waterproof power socket 10 and can be plugged and electrified with a power plug 11 fixed on a connecting circular tube 12. The part of the power cord 3 in the telescopic rod is processed into a spiral shape. 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 configuration, the power cord 3 is prevented from being wound and the power transmission is safe and reliable regardless of the rotation and movement of the mobile device 18. Because the weight of the power line 3 is mainly born by the telescopic rod components, the middle telescopic rods 5-3 and 5-2 can be connected into a plurality of sections, and are very long after being extended. Furthermore, the telescopic pole assembly can be vertically rotated around the upright 2, so that the working area of a single local area 19 can be larger. The structure of the three-phase slip ring a 13 and the three-phase slip ring B6 and the mounting structure between the U-shaped member A4 and the column 2 are common technologies and will not be described in detail herein.

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 telescopic rod component is a circle, after the two sets of components 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 components, 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 telescopic rod component. The telescopic rod assembly in the new working area is pulled over, the waterproof power socket 10 of the telescopic rod assembly is inserted into the power plug 11 on the mobile device B21, the rectangular pipe 9-1 on the telescopic rod assembly in the new working area is moved downwards, the connecting circular pipe 12 is sleeved on the telescopic 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. Of course, a small power battery can be mounted on the mobile equipment to move for a short distance. 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 head section telescopic rod 5-4 adopts a 100 multiplied by 5 circular tube. The cross-sectional dimension of the rest telescopic rods is 20 larger than that of the previous section one by one. The remaining general components, processes, structures are conventional and common technology and will not be described in detail herein.
