Abstract
The invention relates to a ship crane remote hydraulic control system. The system comprises a motor, the output terminal of the motor is connected to an oil pump, the output end of the oil pump is connected to a proportional multi-way valve through an electromagnetic reversing valve, the output terminals of the proportional multi-way valve are connected to a lifting device, a luffing oil cylinder, a telescopic oil cylinder, and a slewer; and the proportional multi-way valve is connected to a remote hydraulic control handle through a hydraulic soft pipe. The ship crane remote hydraulic control system has a compact and reasonable structure, and remotely controls the crane's motions through combining a remote hydraulic control handle and a proportional multi-way valve. The remote hydraulic control handle has a small volume, and does not occupy much space; furthermore, the operation of the handle is convenient, the control pressure of the remote control handle is low, and thus the handle is safer.
Description
Technical field
The present invention relates to weight-lifting equipment technical field, especially a kind of deck crane Remote Hydraulic control system.
Background technology
In prior art, in ship hydraulic hoisting crane, each action of hoisting crane adopts directly operation control on multiway valve of mechanical handle, although this operation is simple and convenient, cost is low.But because the volume of multiway valve is not suitable for being more greatly arranged in driver's cab, the hoisting crane for some with driver's cab, this operating mode just can not meet operating needs.Affect the normal work of hydraulic lift.
Summary of the invention
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of deck crane Remote Hydraulic control system rational in infrastructure, thereby makes it easy to operate, adopts Long-distance Control handle safe, and functional reliability is good.
The technical solution adopted in the present invention is as follows:
A kind of deck crane Remote Hydraulic control system, comprise electrical motor, the mouth of described electrical motor connects oil pump, described oily delivery side of pump is connected with proportional multi-way valve by solenoid directional control valve, and the mouth of described proportional multi-way valve is connected with respectively jack up unit, amplitude oil cylinder, telescopic oil cylinder and turning gear; On described proportional multi-way valve, by hydraulic hose, be connected with Remote Hydraulic control handle.
Further improvement as technique scheme:
Also comprise manual pump, described manual delivery side of pump is connected with solenoid directional control valve;
The return opening of described jack up unit is connected with air cooler by pipeline.
Beneficial effect of the present invention is as follows:
Compact conformation of the present invention, reasonable, by Remote Hydraulic control handle and the mode combining than row multiway valve, realize remote control operation of each action of hoisting crane, Remote Hydraulic control handle volume is little does not take up room for this, easy and simple to handle, the control presssure low-security of this Long-distance Control handle is more reliable.
The present invention has reduced the installation volume of control handle, proportional multi-way valve can be arranged on to driver's cab and carry out Long-distance Control outward, has saved the inner compact space of driver's cab.With low pressure control operation, substituted original high pressure direct control, safety improves.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1, electrical motor; 2, oil pump; 3, proportional multi-way valve; 4, Remote Hydraulic control handle; 5, jack up unit; 6, amplitude oil cylinder; 7, telescopic oil cylinder; 8, turning gear; 9, air cooler; 10, manual pump.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the deck crane Remote Hydraulic control system of the present embodiment, comprise electrical motor 1, the mouth of electrical motor 1 connects oil pump 2, the mouth of oil pump 2 is connected with proportional multi-way valve 3 by solenoid directional control valve, and the mouth of proportional multi-way valve 3 is connected with respectively jack up unit 5, amplitude oil cylinder 6, telescopic oil cylinder 7 and turning gear 8; On proportional multi-way valve 3, by hydraulic hose, be connected with Remote Hydraulic control handle 4; .
Also comprise manual pump 10, the mouth of manual pump 10 is connected with solenoid directional control valve.Manual pump 10 is the in the situation that of system cut-off, and being used for emergent is to use, and realizes the work of hanging of putting of hoisting crane.
The return opening of jack up unit 5 is connected with air cooler 9 by pipeline.The oil liquid temperature being used in cooling line.
Proportional multi-way valve 3 of the present invention is arranged on the driver's cab outside of deck crane.Do not account for the space of driver's cab.Good operating stability, good reliability, easy to use, safe.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
