Abstract
The utility model relates to a remote hydraulic control system for a ship crane. The remote hydraulic control system comprises a motor, wherein the output end of the motor is connected with an oil pump; the output end of the oil pump is connected with a proportional multi-path valve through an electromagnetic reversing valve; the output end of the proportional multi-path valve is connected with a lifting device, a variable-amplitude oil cylinder, a telescopic oil cylinder and a rotating device respectively; the proportional multi-path valve is connected with a remote hydraulic control handle through a hydraulic hose. The remote hydraulic control system is compact and reasonable in structure; remote control operation on all movements of the crane is realized by a remote hydraulic control handle and proportional multi-path valve combination control mode; the remote hydraulic control handle is small in size, does not occupy a space and is simple and easy to operate; the control pressure of the remote hydraulic control handle is low, so that the safety is reliable.
Description
Technical field
The utility model 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.
Utility model content
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 scheme that the utility model adopts 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.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, 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 utility model 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 utility model.
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 utility model 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 described in the utility model 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 to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
