Abstract
The invention belongs to engineering machinery field more particularly to a kind of power supply systems of cable type electric excavator, including excavator, cable and distribution box, further include the roll type rotary supporting part being located on the ground, install vehicular rotary supporting part on board a dredger.The present invention is separately or cooperatively acted on by two collector rings, makes excavator at work, while keeping the 360 degree of accessible rotations of excavator itself and excavator mass motion route, continued power；Keep cable line length controllable by swinging up and down for cable cross bar, avoids touching with excavator；It is significantly reduced distortion, the abrasion of cable simultaneously, prevents security risk, reduces cost depletions.
Description
Technical field
The invention belongs to engineering machinery field more particularly to a kind of power supply systems of cable type electric excavator.
Background technology
Excavator is one of the important equipment in engineering machinery, is applied in various buildings, water conservancy, electric power, mining.
At present in some special operation occasions, power and pollution to excavator have strict demand, therefore cable type excavator occur,
Distribution is introduced from municipal cable and ensures power, while avoiding the various pollutions of conventional diesel.Cable type excavator is general
In the centrally disposed support tower in operating area, for cable to be led to the top of tower, then cable is led into excavator by tower top,
So that cable is powered above excavator, avoids causing to roll from excavation motor spindle access cable.
This cable type excavator deposits problems in：1, when excavator is close to support tower operation, cable occurs
Relaxation, sagging cable are easy to touch initiation accident with excavator；2, when excavator surrounds 360 circular motion of support tower, cable
Line can twist, and when that cable can be caused to scrap more than cable torsional strength, there are power supplies and movement blind area；3, when excavator from
Body needs actions, the cables being connected on excavator motor such as 360 revolutions, front and back, sidesway that can also twist, and equally exists confession
Electricity and movement blind zone problem；4, due to excavator great work intensity, act it is complicated acutely, working environment it is severe, if cable with
Reversed torsion, easy to wear, there are security risks.
Invention content
To overcome above-mentioned technological deficiency, the present invention to disclose a kind of power supply system of cable type electric excavator, the present invention adopts
Technological means is a kind of power supply system of cable type electric excavator, including excavator, cable and distribution box, further includes
Following two parts：
First part is the roll type rotary supporting part being located on the ground, including first support bar in hollow structure and from rolling up
Formula cable drum, the post upper are equipped with the first collector ring, and first collector ring includes rotor and stator, described turn
Son is in hollow structure, and the conductive rotor slideway in the roads N is arranged along rotor subject, and the stator is equipped with can be along rotor slideway
Movable N number of conductive stator sliding block, the top of rotor are fixedly connected with the holder of self-rolling cable drum, stator bottom end with
First support bar is fixedly connected,
Second part is the vehicular rotary supporting part of installation on board a dredger, including second support bar in hollow structure and position
The second collector ring between second support bar and excavator motor, second collector ring is identical as the first collecting ring,
The stator of second collector ring is mounted on excavator motor, and rotor top and the perforation of second support bar bottom of the second collector ring connect
It connects, the second support bar head installation can be with the rotary head of 360 degree of dress rotations.
The principle and advantageous effect of invention：
Power supply flow：Municipal administration draws first segment cable for being electrically accessed distribution box, from distribution box and passes through first support bar inner hollow
Pipeline is connected on the conductive stator sliding block of the first collector ring；One end of second segment cable is connected to the conductive rotor of rotor
On slideway, the other end bypasses self-rolling cable drum, leads to second support bar hollow pipeline by rotary head, is connected to the second current collection
On the stator sliding block of ring；One end of third section cable is connected on the rotor slideway of the second collector ring, and the other end is connected to excavation
On electromechanical machine.Since multiphase is powered, the individual stator of each phase cable connection and rotor slideway.
Self-rolling cable drum is rolled up purchased from market such as Shandong Long Hui hoisting machineries Co., Ltd JTC type product lines simultaneously
Ruler structure can also be considered as open self-rolling cable drum basic structure, therefore those skilled in the art have the ability to realize coil of cable
From rolling up, this is not repeated cylinder.When excavator is close to roll type rotary supporting part operation, cable bears pulling force reduction, self-rolling electricity
Cable reel automatic winding makes cable be in tight state, does not relax, and not will produce the sagging peace touched with excavator of cable
Full hidden danger；
When excavator does circumferential movement around self-rolling rotary supporting part, the rotor of the first collector ring is moved with excavator to be occurred
Rotation, conductive slider is relative to rotor conduction slideway circular motion, and power supply is not interrupted, while each phase cable is not turned round
Song interlocks or rotation, and there is no power supply blind areas, and 360 degree rotation power supply may be implemented；When excavator itself turns round, the second current collection
The rotor of ring is rotated relative to excavator, and conductive slider is not distorted relative to rotor slideway circular motion, each phase cable
Staggeredly or rotation, power supply are not interrupted；When excavator operation itself turns round simultaneously and does circumferential movement, two collector rings are same
Shi Zuoyong still maintains continued power.
