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 precious 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 transmitting power to local mobile equipment in a wired mode. Enabling a mobile device to have a larger working area in a single local area.

Disclosure of Invention

The invention is realized by the following steps: the plurality of upright posts are fixed on two sides of a local area where the mobile equipment works. Two longitudinal beams are arranged above the upright post. The two ends of one beam part are respectively provided with a plurality of rollers which can roll on the longitudinal beams after being placed on the longitudinal beams on the two sides. An upper head of a connecting assembly is mounted on the cross member for rolling movement thereon. The lower head is connected with the mobile equipment. When the mobile equipment moves transversely, the connecting assembly is driven to roll on the beam component. When the longitudinal movement is carried out, the cross beam component is driven to move on the longitudinal beam through the connecting component. The movement in both directions can also be performed simultaneously. A cable drag chain group is arranged on the longitudinal beam on one side and can extend and curl along with the cross beam component. A cable drag chain group B is arranged on the beam component and can extend and curl along with the connecting component. The power line passes through the cable drag chain group on the longitudinal beam and then passes through the cable drag chain group B on the cross beam part to be connected with the junction box on the connecting component. A spiral cable and a power socket with a handle are connected to the lower part of the junction box. The power plug can be plugged and electrified with a power plug connected with the interior of the mobile equipment. Since the weight of the cables is borne by the beam members and the stringers through the cable drag chain sets, 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 the invention is particularly suitable for farmlands.

Detailed Description

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

Referring to figures 1 and 2: two rows of upright posts 1 are fixed on two sides of the working area 10. A longitudinal beam 2 is arranged on the top of each row of upright posts. Two ends of the beam part 7 are respectively provided with 4 rollers A7-1, and one end is fixed with a bracket 7-2. One end of the cable drag chain group 3 is fixed on the longitudinal beam 2, and the other end is hinged with the bracket 7-2 and can be extended or curled along with the rolling of the beam component 7. The upper end of the connecting component 5 is a U-shaped component 5-11, and two sides of the inner side of the U-shaped component are respectively provided with 4 rollers B5-9 which can roll on the beam component 7. One end of the cable drag chain group B9 is fixed at the root of the bracket 7-2, and the other end is hinged with the upper part of the U-shaped member 5-11 and can be extended or curled along with the rolling of the connecting component 5. The power cord 6 extends from the ground to one end of the cable drag chain group 3, penetrates into the inner cavity of the cable drag chain group, penetrates out from the other end, enters the inner cavity of one end of the cable drag chain group B9, penetrates out from the other end, and is connected and fixed in the junction box 5-10 on the U-shaped component 5-11. One end of the spiral cable 5-12 is connected in the junction box 5-10, the other end is connected with a three-phase power socket 5-13 with a handle, and after the three-phase power plug 5-15 connected with the inside of the mobile device 8 is inserted, power electricity can be transmitted to the mobile device 8.

Referring to figures 2, 3: the lower part of the U-shaped component 5-11 is welded with a section of round tube A5-8 which is transversely provided with a round hole, the other section of round tube B5-5 which is coaxial with the round tube A5-8 and has the same outer diameter as the round tube A5-8 is also transversely provided with a round hole, and a cross connecting piece 5-7 is sleeved outside the sections of round tube A5-5 and the round tube A5-8. Two groups of holes are arranged on the upper and lower parts of the cross connecting piece 5-7 in the transverse direction, the axes of the two groups of holes intersect at 90 degrees and are hinged with the transverse round holes on the circular tubes A5-8 and the circular tubes B5-5 through 2 pin shafts 5-6. The lower part is also provided with a section of round pipe C5-3 with the same excircle as the round pipes A5-8 and the round pipes B5-5, and the round pipes C5-3 are welded on the bottom plate 5-1. When the axial distance between the circular tubes B5-5 and C5-3 is too large or too small due to different heights of various mobile devices, the circular tubes B5-5 with different lengths can be exchanged for adjustment. The bottom plate 5-1 is fixed on the mobile device 8 through four bolts 4. The outside of the round tube B5-5 and the round tube C5-3 is sleeved with a connecting tube 5-4 with the inner diameter slightly larger than the outer diameter of the round tube B5-5 and the round tube C5-3. The connecting pipe 5-4 can slide up and down under the drive of the handle 5-16. The handle 5-16 is also a U-shaped member, the middle of which is hinged with two small brackets 5-2 welded on the bottom plate 5-1, and can rotate and swing at a certain angle. When one end of the connecting tube is manually rotated to be close to the bottom plate 5-1 (as shown in the state of attached figures 1, 2 and 3), the connecting tube is clamped by the elastic clamping feet 5-14 fixed on the bottom plate 5-1, and the other end of the connecting tube is rotated upwards to support the connecting tube 5-4. The moving device 8 and the connecting assembly 5 are now in a connected state, and the connecting assembly 5 and the beam member 7 can be driven to move along with it. When the elastic clamping feet 5-14 are pushed away, the handles 5-16 rotate reversely (see arrows in figures 1, 2 and 3), the connecting pipe 5-4 slides down to the bottom and is separated from contact with the circular pipe B5-5. At this point, the mobile device 8 can be disengaged from the set of connection assemblies 5. The set of connection assemblies ensures a reliable connection and disconnection of the cross member 7 and the movement device 8 in case of uneven working areas. The spiral cables 5-12 can be normally powered even if the mobile device 8 is rotated 180 degrees.

Referring to fig. 4: this is an example in the field, setting A, B, C, D four working areas 10 of the same size. In order to reduce the number of the upright columns 1, two groups of stay cables 11 are arranged on each middle upright column heightening section 12 to pull and fix the longitudinal beams 2 and keep the horizontal state of the longitudinal beams. Four local installations 4 groups of beam parts 7, cable drag chain groups 3, cable drag chain groups B9, power lines 6 and part of the members of the connection assembly 5. Assuming that the mobile device 8 works in the working area A, after the work is finished, the mobile device 8 is moved to the working area B or the working area C, the elastic clamping feet 5-14 are pushed open, the handles 5-16 rotate reversely, the connecting pipe 5-4 slides down to the bottom, and the connecting pipe 5-4 is separated from the circular pipe B5-5. The connecting members 5 of work area a are then pushed open and connected to the connecting members 5 of work area B or work area C. And then the three-phase power socket 5-13 with the handle of the working area A is pulled down and is inserted into the three-phase power plug 5-15 connected in the working area B or the working area C, so that the mobile equipment 8 can be moved to the working area B or the working area C to normally work. The circulation can be repeated, and the work areas can also work similarly.

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 installed on the mobile equipment, and the common technology can solve the problem.

In this embodiment, each working area 10 is 500 meters by 100 meters in size. The longitudinal beams 2 are 300 × 150 rectangular tubes, and the main body of the cross member 7 is also 300 × 150 rectangular tubes. The longitudinal beam 2 and the cross beam member 7 are connected in the length direction in a conventional and common technology, and therefore, the process is not described in detail. The column heightening section 12 adopts a reinforced concrete pole 10 meters long. The stay cable 11 is made of phi 11 galvanized steel wire rope.
