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.
Conventional excavators product is using fuel engines as power source, the disadvantage is that engine consumption is big, operating cost is high, discharge and noise are dirty
Dye is serious, therefore occurs electric hydraulic excavating machine at present and substitute traditional equipment.Due to the electric excavator of current storage battery, battery
There are no extensive uses for technology, and there are the excessively high high-power operation uses with the limited not competent excavator of storage capacity of cost, need
The cable type electric excavator of municipal cable distribution is introduced, such case is generally in the centrally disposed tower crane knot in operating area
Cable is led to the structural top, then draws and be connected on excavator by structure, is kept cable to power above excavator, is avoided from bottom
Access cable causes to roll.This cable type excavator deposits problems in：1, excavator is needed in a certain range of work
Irregular line-of-road movement in industry region, but cable line length, which is the zone of action maximum radius length, to immobilize, therefore work as
For excavator when close to tower crane operation, cable slack is larger, is easy to touch initiation accident with excavator；2, excavator moving region
It is generally fan-shaped or round, while excavator itself needs the actions such as revolution, front and back, sidesway, and cable type excavator multiphase is electric
Cable can not rotate holding continued power repeatedly therewith, reduce operating efficiency；3, it due to excavator great work intensity, acts complicated acute
It is strong, working environment is severe, cable is easily damaged, and 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：It is located the vehicular rotation branch of sliding weight of steelyard formula rotatable support structure and installation on board a dredger on the ground
Support structure cooperates continuously powers for the excavator of operating：
First part is the sliding weight of steelyard formula rotatable support structure being located on the ground, including first support bar in hollow structure and electricity
Cable cross bar, the first support bar upper end 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 installation can be along rotor slideway on the stator
Movable N number of conductive stator sliding block, the top of rotor are connect by articulated form with cable cross bar, stator bottom end and first
Supporting rod is fixedly connected, and one end of the cable cross bar is equipped with counterweight,
Second part is installation vehicular rotatable support structure on board a dredger, including second support bar in hollow structure and
The second collector ring between second support bar and excavator motor, second collector ring and the first collecting ring phase
Together, the stator of the second collector ring is mounted on excavator motor, and rotor top and the second support bar bottom of the second collector ring are passed through
Logical, the second support bar head installation can be with the rotary head of 360 degree rotation.
Further, the power supply system of cable type electric excavator of the present invention, the cable cross bar middle part, which has, to be added
Gu bar, reinforcing bar top and cable cross bar both ends steel wire rope reinforcement by connection.
The principle and advantageous effect of invention：
Power supply flow：By municipal administration for being electrically accessed distribution box, draws first segment cable from distribution box and pass through in first support bar inside
Vacant duct is connected on the conductive stator sliding block of the first collector ring；One end of second segment cable is connected to conductive turn of rotor
On sub- slideway, the other end passes through cable cross bar, leads to second support bar hollow pipeline by rotary head, is connected to the second collector ring
On stator sliding block；One end of third section cable is connected on the rotor slideway of the second collector ring, and it is electromechanical that the other end is connected to excavation
On the input terminal of machine, complete a whole set of power supply system is constituted.
Collector ring principle：When excavator needs to do circumferential movement around sliding weight of steelyard formula rotatable support structure, the first collector ring
Rotor rotate therewith, conductive slider relative to rotor slideway circular motion, each phase cable be not distorted staggeredly or rotation,
Power supply is not interrupted；When excavator itself turns round, the rotor of the second collector ring is rotated relative to excavator, and conductive slider is opposite
In rotor slideway circular motion, each phase cable is not distorted staggeredly or rotation, power supply are not interrupted；Work as excavator operation
When itself turning round simultaneously and do circumferential movement, two collector rings act on simultaneously.
Counterweight principle：When excavator is close to sliding weight of steelyard formula rotatable support structure, second segment cable tension reduces, balance
Counterweight is sunk under the effect of gravity, and second segment cable is made to keep tight state, will not be contacted with excavator because of cable slack.
The beneficial effects of the invention are as follows：By two collector ring collective effects, make excavator at work, keeps excavator
Itself and the 360 degree of accessible rotations of excavator mass motion route, continued power；Make cable by swinging up and down for cable cross bar
Straight condition is tightened in line holding, avoids touching with excavator；It is significantly reduced distortion, the abrasion of cable simultaneously, prevents safety
Hidden danger reduces cost depletions.
