The specific embodiment
Below, the electric power system of the electric excavator of embodiment of the present invention is described with reference to Fig. 1～Fig. 5.
Like Fig. 1～shown in Figure 3, electric excavator mainly has top cycle body 1 and lower running body 2.At the rear portion of lower running body 2, dispose power supply through bindings such as pins 8 and use the cables reel assembly.
(power supply is with the formation of cables reel assembly)
Like Fig. 2, shown in Figure 3, power supply with the cables reel assembly comprise the cables reel 4 of assembly frame 7, rolled power cable 11,11 channeling conducts make it fitly be wound on cable guide device 5 on the cables reel 4, cables reel 4 is rotated the cables reel drive unit 3 of driving and the controller 6 that cables reel drive unit 3 is controlled to power supply cable.What is called is rolled power cable 11 fitly, is meant that the power supply cable that is wound on the cables reel 4 is parallel to each other and not overlapping at same winding layer.
Be provided with chain between cables reel 4 and the cables reel drive unit 3 and between cables reel 4 and the cable guide device 5, will be passed to cables reel 4 and cable guide device 5 from the rotary power of cables reel drive unit 3 through this chain.
(power supply is with the installation constitution of cables reel assembly and lower running body)
Lower running body 2 has running body frame 12, and central authorities are provided with the upwardly extending installing rack 13 in the vehicle body front and back at the rear portion of this running body frame 12, this installing rack 13 than the bogie side frame 12a of running body frame 12 also laterally (vehicle body rear side) outstanding.Outboard end (vehicle body rear end) at this installing rack 13 is provided with the installation portion of power supply with the assembly frame 7 installation usefulness of cables reel assembly.
Like Fig. 4, shown in Figure 5, this installation portion is constituted as to offer to fix with pin inserts general through hole, also has the positioning pin 8c as fastening portion integratedly.In addition, this installation portion also has joint 10.Joint 10 comprises the running body side connector 10a on the power supply cable 11a that is connected the walking side and is connected the assembly side connector 10b on the power supply cable 11b that assembles the side.The power supply cable 11a on walking side is fixed on the inwall of installing rack 13, and the power supply cable 11b on assembling side is fixed on the inwall of assembly frame 7.
Power supply forwards is provided with installation highlightedly with the assembly frame 7 of cables reel assembly and uses board 7a1 in the end of its vehicle body front side; Offer in this installation and fixingly to insert general through hole, below this through hole, be formed with roughly inverted U-shaped fastening recess 7a2 with pin with board 7a1.
In the 13 last times of installing rack that will power supply be installed in the walking side with the cables reel assembly; Clip the installation portion of installing rack 13 from the outside of vehicle body left and right directions with board 7a1 with the installation of assembly frame 7; Under this state, make the fastening recess 7a2 fastening of installing with board on the positioning pin 8c that is arranged on integratedly on the installation portion, and make and install with the through hole of board 7a1 and fixing of installation portion with the slotting general through hole contraposition of pin; Then, will fix to insert and lead in these through holes with pin 8a.Have flange at fixing head with pin 8a, the installation that this flange is fixed on assembly frame 7 through bolt 8b is with on the board 7a1.Then, the joint 10a on walking side is connected with the joint 10b that assembles the side, and the other end that will assemble the power supply cable 11 on side is connected on the external power source, constituted the electric power system of electric excavator thus.
Under the situation about pulling down from the installing rack 13 on walking side of when carrying waits, need will supplying power with the cables reel assembly; Take off the fixing pin 8a that uses as long as unclamp bolt 8b; Then the connection of joint 10 is removed; So that joint 10 is divided into walking side joint 10a and assembly side connector 10b, just can power supply be pulled down from the installing rack 13 on walking side with the cables reel assembly.
Thus; In the electric power system of electric excavator of the present invention; Can walk being connected of assembly frame 7 and being connected and being connected releasing of the power supply cable on dismounting and walking side and the power supply cable of assembling the side on installing rack 13 and assembling side on side with simple mode; Therefore, the assembling of the electric power system of electric excavator and decomposition become easily, just can transport electric power system of the present invention and use the electric excavator of this electric power system through general trailer.
And, since installing rack 13 than the bogie side frame of running body frame 12 also laterally (vehicle body rear side) outstanding, so in the assembling of the electric power system of carrying out electric excavator with when decomposing, the operating space is big, is convenient to operation.
More than, an embodiment of the electric power system of electric excavator of the present invention is illustrated, but the invention is not restricted to above-mentioned embodiment, in the scope that does not break away from the purport of the present invention that claims put down in writing, can carry out various changes.
