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

Ship crane remote hydraulic control system
Technical field
The present invention relates to technical field of crane equipment, especially a kind of ship crane remote hydraulic control system.
Background technology
In prior art, in ship hydraulic hoisting crane, each action of hoisting crane adopts mechanical handle directly operation control on multiway valve, although this operation is simple and convenient, cost is low.But the volume due to multiway valve is not suitable for more greatly being arranged in driver's cab, for some hoisting cranes 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 ship crane remote hydraulic control system rational in infrastructure, thus makes it easy to operate, and adopt the safety of Long-distance Control handle high, functional reliability is good.
The technical solution adopted in the present invention is as follows:
A kind of ship 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 to jack up unit, amplitude oil cylinder, telescopic oil cylinder and turning gear; Described proportional multi-way valve is connected with Remote Hydraulic control handle by hydraulic hose.
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, rationally, the remote control operation of each action of hoisting crane is realized by Remote Hydraulic control handle and the mode combined than row multiway valve, 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.
Present invention decreases the installation volume of control handle, proportional multi-way valve can be arranged on outside driver's cab and carry out Long-distance Control, save the space that driver's cab is inner compact.Instead of original high pressure direct control with low pressure control operation, 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.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the ship 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 to jack up unit 5, amplitude oil cylinder 6, telescopic oil cylinder 7 and turning gear 8; Proportional multi-way valve 3 is connected with Remote Hydraulic control handle 4 by hydraulic hose; .
Also comprise manual pump 10, the mouth of manual pump 10 is connected with solenoid directional control valve.Manual pump 10 is when system cut-off, and being used for emergent is use, and what realize hoisting crane puts the work of hanging.
The return opening of jack up unit 5 is connected with air cooler 9 by pipeline.The oil liquid temperature be used in cooling line.
The driver's cab that proportional multi-way valve 3 of the present invention is arranged on deck crane is outside.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, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
