Tension is excessively loose, and especially when turning, venting efficiency is very low, is also easy to cause cable fault.
(2) unwrapping wire arm lengths be generally 3 meters, weight be 1.5 tons or so, pass through height and posture manual adjustment adapt to tunnel
When turn curvature radius, large labor intensity.
It (3) is the driving requirement for meeting drum, structure is complicated and volume is big for respective drive component, so that railcar integrally weighs
Amount is big.
The structure design for advanced optimizing the railcar for cable laying, so that it more can easily apply to
Subway tunnel construction, is those skilled in the art's technical problem urgently to be resolved.
Summary of the invention
For the structure design for advanced optimizing the railcar for cable laying set forth above, so that it can be more
The technical issues of easily to apply to subway tunnel construction, the present invention provides a kind of tracks for Metro Cable laying
Vehicle.The structure design of this railcar facilitates power required for matching cable laying.
In view of the above-mentioned problems, a kind of railcar for Metro Cable laying provided by the invention passes through following technical essential
To solve the problems, such as: a kind of railcar for Metro Cable laying, including railcar ontology are provided on the railcar ontology
Cable disk, drum drive system, unwrapping wire arm and unwrapping wire arm drive system, the drum drive system is for driving cable disk
Rotation, for driving, unwrapping wire arm is gone up and down the unwrapping wire arm drive system and rotation, the drum drive system and unwrapping wire arm drive
System is electro-hydraulic drive system, and accumulator is provided in electro-hydraulic drive system, in the accumulator and electro-hydraulic drive system
The circuit line at hydraulic pump outlet end connects: in hydraulic pump works, the accumulator can store the pressure energy from hydraulic pump,
And accumulator can release energy to the executing agency in electro-hydraulic drive system.
In the prior art, for the railcar laid for Metro Cable, corresponding drum drive system generally uses drum
The drive scheme of motor, since cable disk weight itself is big and quantity is more, therefore required cable power of motor is larger, for matching
Driving torque needed for cable disk, retarder is matched in installation on the output end of online coil motor, but considers the body of drum motor
Product, the power of ordinary circumstance uncoiling plate motor do not have it is more more than needed, i.e., when loading larger, generally by slowing down unwrapping wire speed
The mode of degree completes cable laying.In subway tunnel turning, due in the way of drum motor direct-drive cable disk
Cable disk revolving speed adjustment difficulty is big, therefore is the matching railcar speed of travel and cable drum speed, to maintain the tension of cable,
Cable fault or the bad problem of laying quality easily occur when tunnel is turned.
In the prior art, it for electro-hydraulic drive system, is traditionally arranged to be including oil circuit, fuel tank, motor, hydraulic pump, is liquid
The executing agency of pressure motor or hydraulic cylinder, valve etc., the motor is for driving hydraulic pump works, with hydraulic after being pressurizeed
Oil, the valve include overflow valve, check valve, reversal valve, switch valve etc., and the fuel tank is for storing the hydraulic of oil circuit to be sucked
Oil and storage are by the hydraulic oil released in oil circuit.
In the present solution, setting are as follows: the drum drive system and unwrapping wire arm drive system are electro-hydraulic drive system, and electricity
Accumulator is provided in liquid drive system, the circuit line at hydraulic pump outlet end connects in the accumulator and electro-hydraulic drive system
Connect: in hydraulic pump works, the accumulator can store the pressure energy from hydraulic pump, and accumulator can be to electro-hydraulic drive system
In executing agency release energy.It, can be by not carrying out in smooth cabling process or cable laying in specific use
When, motor drives hydraulic pump works, and accumulator stores the pressure energy exported by hydraulic pump；Speed change is needed in cable disk to adapt to
When the railcar ontology speed of travel, in the case where electric machine operation state can be constant, respective valves in electro-hydraulic drive system are utilized
Electro-hydraulic drive system working condition is adjusted, when needing underdrive such as cable disk, is stored by accumulator and is exported by hydraulic pump
Pressure energy, overflow valve opening adjustment in oil circuit, change etc. as the hydraulic motor displacement of executing agency so that cable disk subtracts
Speed rotation.When cable disk needs to accelerate rotation, stored hydraulic oil exports energy to executing agency by oil circuit in accumulator
