Device is helped to design, in particular to one kind is fixedly mounted on electric excavator, service cable when as electric excavator operation
The device of swinging support.
Background technique
Currently, the conventional hydraulic excavator using internal combustion engine as a power, has and relies on petroleum resources, noise and row
The shortcomings that putting serious pollution environment.Motorized has gradually become an important development direction of excavator.In addition, China certain
A little special regions, electric power resource is very rich, and electricity price is very cheap, is not only facilitated using electric excavator, but also can be big
Amplitude reduction energy consumption cost.
So far, no matter electric excavator itself or its power supply system, it there is no mature engineering product, technically still need to
Solve key technology problems.In the power supply power supply of electric excavator is imagined, at this stage, based on the towed electricity for changing electric thought
Source vehicle is one of the feasible program of electric excavator power supply, and basic ideas are that dragging one is equipped with electricity behind electric excavator
The towed vehicle of source device provides power supply for electric excavator.Secondly, also there is part electric excavator can be in fixed yard
Operation is carried out, scope of activities is little, therefore can use AC380V external power supply nearby.
Under both of these case, the power supply power supply of electric excavator requires the towed supply vehicle or external by being located at ground
Power supply is transmitted through the cable on the vehicle of excavator.Since excavator is frequently moved and turned to when operation, getting on the bus for excavator is
The opposite system of getting off of system is frequently turned round, and the impact of towed supply vehicle, the winding of cable, bending and mechanical interference, friction are caused
The problems such as.It is in the prior art the service cable " retinue " for solving the problems, such as electric excavator, it has to use a series of complex
Mechanism, increase operation cost, reduce the reliability and economy of excavator.
Currently, connecing the cable on motor in addition to folding and unfolding needs coil of cable to install around in electric excavator work operations
Set realization；And with the movement of electric excavator or upper-part rotation, service cable again with the job run direction of excavator with
Row is consistent, cable usually occurs in underground and pulls bending or extrusion abrasion at abrasion or drawing cable mouth, the time occurs not long
Electric leakage and power-off, influence operation safety, jeopardize equipment and personal safety.
Summary of the invention
Deficiency discloses a kind of electric excavator cable swinging rod device to the utility model according to prior art.This is practical new
Type scheme is intended to reduce impact of the cable flexing to supply vehicle, and the constraint of cable, efficiently avoids cable when getting rid of operation
Winding, bending and mechanical interference, friction the problems such as.Structure is simplified, operating efficiency, the safety of electric excavator are improved
Property and economy.
The utility model is achieved through the following technical solutions:
Electric excavator cable swinging rod device excavates the bracket of railcar body including being fixedly installed on, it is characterised in that: described
Cantilever tip has pedestal, and pedestal rotatably couples with the swing rod of lateral arrangement column structure, and swing rod can be around pedestal along plane 180 degree
Rotation.
There is the shaft being vertically arranged in the base center portion, and shaft is coupled by bearing with base rotation, swing rod and shaft
It is connected and fixed and is rotated with shaft.
Cloth is provided with card line folder and is used to support suspended cables in the swing rod transverse direction.
The annulus that the swing rod lateral end is provided with suspension is used to support suspended cables.
There are oil sealing and backpack cover to be environmentally isolated on the outside of the shaft and bearing, backpack cover is provided with the oil for filling lubricating oil
Mouth.
The utility model proposes a kind of electric excavator cable swinging rod device, be made of bracket, pedestal and swing rod, prop up
Frame is fixedly mounted on electric excavator car body upper end, and bracket supports firm banking, and pedestal inner hole both ends are separately installed with sliding axle
It holds, plain bearing bore is provided with shaft, and sliding bearing outer ring fixing assembling has swing rod, and the swing rod can turn around fixed rotating shaft
It is dynamic, card line folder and garden ring are installed, for fixing cable on the swing rod.Swing rod drives cable, can freely exist around fixed rotating shaft
Rotary oscillation in the range of 180 degree, thus realize service cable with electric excavator rotary table job run direction with
Row is swung.
The utility model electric excavator cable swinging rod device realizes service cable and swings and electric excavator operation fortune
The retinue of line direction is consistent, guarantees the synchronism in the job run direction of connecting cable and electric excavator, improves electronic excavation
Reliability, safety and the operating efficiency and economic benefit of machine.
Compared with prior art, the utility model effect of electric excavator cable swinging rod device is: avoiding cable and fixes
Connection unfavorable constraint, so as to avoid cable the towing abrasion of excavator junction or extrusion abrasion and caused by electric leakage or
Power-off.The utility model has substantially met cable flexing with the rotary freedom of the 180 degree of cable swinging rod and excavator operation is transported
The retinue of line direction is consistent, it is ensured that greatly improves service life, the reliability and safety of cable.
