Description
Technical field
The utility model relates to braking device technical field, the independent hydraulically controlled braking system of especially a kind of electronic crane.
Background technique
Crane, claims again loop wheel machine peculiar to vessel, ship's crane, is the large deck machinery of one on ship, and it is a kind of equipment of ship loading and unloading goods, and hydraulic pressure crane is a kind of cargo handling appliance generally using on boats and ships.
The electronic crane of prior art, the action of hoisting in its working procedure, revolution, luffing all has variable-frequency motor to drive, and reductor braking device is motor braking, its complex structure, cost is higher.
Model utility content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of independent hydraulically controlled braking system of electronic crane rational in infrastructure, thereby adopts independent hydraulic power unit, and simple in structure, cost is low.
The technological scheme that the utility model adopts is as follows:
The independent hydraulically controlled braking system of a kind of electronic crane, comprise the pump being connected with fuel tank, described pump drives by motor, described delivery side of pump connects one-way valve, reduction valve and solenoid directional control valve successively by in-line, described solenoid directional control valve is by return line oil sump tank, the output terminal connecting brake of described solenoid directional control valve, described break connects speed reducer; The oil inlet pipe in described one-way valve outlet port is provided with accumulator by the first pipeline, and antidetonation pressure gauge with electric contact is installed in described the first pipeline end, is also separately installed with hand pump and the second relief valve on described the first pipeline; Between the in-line at pump discharge place and return line, the first relief valve is installed.
Further improvement as technique scheme:
On the in-line of installation reduction valve, pressure gauge is also installed.
The beneficial effects of the utility model are as follows:
The utility model compact structure, reasonable, easy to operate, operational safety is high, and Security is good, adopts independently hydraulic pump station structure, takes up room little, and cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, break; 2, speed reducer; 3, solenoid directional control valve; 4, pressure gauge; 5, reduction valve; 6, one-way valve; 7, accumulator; 8, antidetonation pressure gauge with electric contact; 9, the second relief valve; 10, the first relief valve; 11, hand pump; 12, motor; 13, fuel tank; 14, pump.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the independent hydraulically controlled braking system of electronic crane of the present embodiment, comprise the pump 14 being connected with fuel tank 13, pump 14 drives by motor 12, the output terminal of pump 14 connects one-way valve 6, reduction valve 5 and solenoid directional control valve 3 successively by in-line, solenoid directional control valve 3 passes through return line oil sump tank 13, the output terminal connecting brake 1 of solenoid directional control valve 3, and break 1 connects speed reducer 2; The oil inlet pipe in one-way valve 6 outlet ports is provided with on accumulator 7, the first pipeline ends installation antidetonation pressure gauge with electric contact 8, the first pipelines and is also separately installed with hand pump 11 and the second relief valve 9 by the first pipeline; Between the in-line in pump 14 outlet ports and return line, the first relief valve 10 is installed.
On the in-line of installation reduction valve 5, pressure gauge 4 is also installed.
In actual using process, worked by motor 12 driven pumps 14, hydraulic oil is transported in accumulator 7 from fuel tank 13, carry out accumulation of energy.In the time that speed reducer 2 is worked, solenoid directional control valve 3 is opened, and hydraulic oil is from accumulator 7 process solenoid directional control valves 3 to normally closed brake 1, and normally engaged brake 1 unclamps.On the contrary, in the time that speed reducer 2 quits work, solenoid directional control valve 3 cuts out, hydraulic oil oil sump tank 13, and break 1 closure, plays braking action.
Accumulator 7 is set upper downforce by antidetonation pressure gauge with electric contact 8, and when pressure is during higher than upper pressure, motor 12 quits work, and plays a protective role.The design of one-way valve 6, can prevent that hydraulic oil from refluxing.When pressure is when pressing down, motor 12 is started working.Avoid motor 12 and pump 14 to work long hours, improved its utilization efficiency, extended its working life.
Reduction valve 5 controls to the pressure on break 1 by pressure gauge 4, ensures that the pressure on arrival break 1 is suitable.
The effect of the first relief valve 10 and the second relief valve 9 is in the time of overpressure, plays decompression.
When there is urgency, motor 12 is not worked, and can give accumulator 7 oilings by hand pump 11, and pressure rise, can carry out the operation of next step action.It is easy to use, simple in structure, and cost is low.
More than describing is to explanation of the present utility model, is not the restriction to model utility, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
