Embodiment
The present embodiment selection three-phase alternating current mode is illustrated, and direct current supply mode can also be used in concrete application.
As Figure 1-Figure 4, the power supply system of electronic construction machinery includes power supply mechanism and by motor structure in the hole；It is described
Power supply mechanism includes the power supply coil holder 1 being erected in hole and is disposed there above at least along electronic 2 direction of travel of construction machinery
One power supply line 3, the power supply line 3 are set on the power supply coil holder 1 by suspention line 4, it is described by motor structure including setting
It is used to lead with what the power supply line 3 contacted in the lifting assembly at electronic 2 top of construction machinery and at the top of lifting assembly
It is in electrical contact band 5, the bidirectional cambered surface structure to raise upward centered on the conductive contact band 5, and works as 5 top of conductive contact band
When power supply line 3 is a plurality of, the height of each setting in a plurality of power supply line 3 is and on the conductive contact band 5
The globoidal structure on surface matches.
Power supply line 3 is erected at the supply lines above electronic 2 travel line of construction machinery by suspending line 4 in midair by power supply mechanism
On frame 1, independent power supply line 3 can be respectively set into and out of both direction by electronic construction machinery 2, a side can also be only set
To power supply line 3.Power supply line 3 can be attached on rigidity metallic matrix (conducting wire and rigidity metal using by flexible cable
Supplemental dielectric layer between matrix, avoid rigidity metal-based layer charge) etc. modes be powered.Lifting by controlling lifting assembly can
Contact conductive contact band 5 with power supply line 3, the surface of conductive contact band 5 is using the easy conductives substances such as carbon sliding block, center
The bidirectional cambered surface structure that place raises upward, i.e., in three top that power supply line 3 contacts with conductive contact band 5, front side, rear side portions
There is carbon sliding block in position, it is ensured that reasonable, reliable contacts in the different tightness of power supply line 3, in structure carbon sliding block with lead
It is arranged to detachable structure between electrical contact band 5, is conveniently replaceable.Different, 5 table of conductive contact band according to the number of phases of power supply line 3
The carbon sliding block in face is combined by different quantity.The present embodiment is three-dimensional power supply line 3, and the carbon on 5 surface of conductive contact band is sliding
Block is combined into an entirety by three pieces.
Its specific working principle are as follows: because conductive contact band 5 need to keep well contacting with three-phase power line 3, and it is each
3 tightness of power supply line is different, and conductive contact band 5 and three-phase power line 3 are face contact (3 points at face), ensures difficulty very
Greatly.However, conductive contact band 5 be bidirectional cambered surface structure, and in a plurality of power supply line 3 each setting height with conduction
The globoidal structure of contact 5 upper surface of band matches, in this way, three-phase power line 3 is in that an intermediate phase power supply line 3 is high, both sides two
The low domes of phase power supply line 3 are advantageous to power supply line 3 and contact with the effective of conductive contact band 5.When an intermediate phase

Block contact, the carbon shoe contact at 5 top of both sides two-phase power supply line 3 and conductive contact band；So electronic construction machinery 2 retreats
When, power supply line 3 and the 5 rear side carbon shoe contact of conductive contact band of pine are compared in centre one, and tight power supply line 3 is compared on both sides two
With 5 top carbon shoe contact of conductive contact band.When an intermediate phase power supply line 3 is relatively tight, when both sides two-phase power supply line 3 is more loose
It is intermediate when (as shown in Figure 6), conductive contact band 5 and three-phase power line 3 contact, and when electronic construction machinery 2 advance at this time
One compares tight power supply line 3 and 5 top carbon shoe contact of conductive contact band, both sides two-phase power supply line 3 and conductive contact band 5
Front side carbon shoe contact；When such electronic construction machinery 2 retreats, centre one is compared tight power supply line 3 and conductive contact band 5 and is pushed up
Portion's carbon shoe contact, the more loose two-phase power supply line 3 in both sides and 5 rear side carbon shoe contact of conductive contact band.
In the present embodiment, as shown in Fig. 3, Fig. 4 and Fig. 7, the top of the conductive contact band 5 is equipped with to be supplied for separating three-phase

The high pressure gas holder 12 that cylinder 11 connects.
Lifting assembly working principle: high pressure gas holder 12 discharges high pressure gas into driving cylinder 11 by air valve 13, driving
11 quick acting of cylinder, driving scissor-type lifting platform 8 is steady, fast lifting, until three-phase power line 3 and conductive contact band
Stop rising after 5 whole contacts, vice versa；Select scissor-type lifting platform 8 as the core component of lifting assembly, and scissor
The lifting pattern of formula hoistable platform 8 is vertical lift, and having the advantage that relative to lift forward or backward lift can
It avoids being occurred dry by components (such as rear carriage of dump truck body, backhoe armed lever) collision on motor structure and electronic construction machinery 2
It disturbs；Road surface is more jolted in hole, can avoid lifting assembly deformed damaged, from prolonging its service life.
A pair of of stabilizing spring 14, the drive are equipped in the present embodiment, between the both ends of the connecting rod 10 and the top of pedestal 7
It takes offence and is connected by spherical joint 15 between the telescopic rod and the connecting rod 10 of cylinder 11.
Stabilizing spring 14 and the support rod 9 of scissor-type lifting platform 8 act synergistically, and guarantee the stabilization by motor structure, make to supply
Electric line 3 is continuously electronic construction machinery 2 and powers.Electronic construction machinery 2 is larger in Fast marching process vibrations, and road surface is run in addition
Winnow with a dustpan, conductive contact band 5 and the frictional force of power supply line 3 are larger, have curved effect to lifting assembly, although this flecition compared with
The lifting assembly of lift forward mentioned above or backward lift is smaller, but in order to avoid long term leads to lifting assembly
Deformation, therefore it is additionally arranged stabilizing spring 14.The concrete operating principle of stabilizing spring 14 are as follows: when lifting assembly is bent to a direction,
14 stress of stabilizing spring of other side stretches, and the amount of bow of lifting assembly is on the one hand reduced, on the other hand in conductive contact band 5
Lifting assembly rapid return is helped when disengaging with power supply line 3, in addition also by the spherical shape with driving 11 telescopic rod of cylinder
(when lifting assembly bending, only rotate at spherical joint 15 15 collective effect of joint deformation, and driving cylinder 11 is not sent out
Change shape), it avoids being deformed influence to driving cylinder 11.
