Background technology
At present, braking equipment is widely used in the industries such as colliery, lifting, metallurgy, engineering machinery, and braking is set
The standby throat link as operation system, plays vital effect.It is special that brake force is referred to as braking with the change of braking time
Linearity curve, characteristic quality is weighs the important indicator of braking stationarity, and braking is unstable to cause device damage, influence
Personal safety.Current existing disc brake apparatus is typically configured with hydraulic system, and hydraulic system is by multiple overflow valves and choke valve
Use cooperatively, form ladder pressure, brake relatively steady.But this mode is not appropriate for length away from belt from conveyer braking time
The operating mode that band-type brake is slowly opened when longer and lower fortune is started, lower fortune band-type brake is too fast to be opened, and is likely to result in car slipping, is damaged starting and is set
It is standby.
As can be seen here, prior art awaits further improving.
Utility model content
The utility model is the weak point that avoids above-mentioned prior art from existing there is provided a kind of braking characteristic curve is good,
Braking, switching-off time adjustable range are wide, it is adaptable to the disc brake apparatus of multi-state VFC hydraulic system.
The technical scheme that the utility model is used for：A kind of disc brake apparatus VFC hydraulic system, including
Fuel tank, fuel tank, which is connected with oil feeding line and brake circuit, oil feeding line, sequentially to be concatenated oil absorption filter, gear pump, height and presses through
Filter, check valve and oil cylinder；Choke valve, flame proof reversing globe valve and accumulator are concatenated on brake circuit；The oil feeding line and system
The end of dynamic oil circuit forms the connected state mutually crossed by connecting oil circuit, the end concatenation pressure gauge of the connection oil circuit with
Pressure sensor；It is also associated with manual pump on the oil feeding line, the manual pump and gear pump phase simultaneously connect；The oil feeding line
On also branch out to have on overflow oil circuit, the overflow oil circuit and concatenate overflow valve in two parallel branches, a parallel branch, it is another
Concatenation cut-off ball valve in bar parallel branch, the end connection fuel tank of the overflow oil circuit；The gear pump is by Frequency Converter Control electricity
Machine drives.
The motor is common electric machine or variable-frequency motor.
By adopting the above-described technical solution, the utility model achieves beneficial effect.
1st, the utility model braking, switching-off time adjustable range are wide, and linear brake can be achieved, and brake very steady.
2nd, using variable frequency adjustment, multiple hydraulic valves are eliminated, maintaining is convenient, reduces fault rate, added reliable
Property.

Embodiment
This practicality is newly described in further detail with specific embodiment below in conjunction with the accompanying drawings, but the utility model is simultaneously
It is not limited to these embodiments.
As shown in figure 1, a kind of disc brake apparatus VFC hydraulic system, including fuel tank 1, fuel tank 1 is connected with confession
Oil absorption filter 4, gear pump 5, high pressure filter 7, check valve 8 are sequentially concatenated on oil circuit 2 and brake circuit 3, oil feeding line 2
And oil cylinder 15；Choke valve 13, flame proof reversing globe valve 12 and accumulator 14 are concatenated on brake circuit 3；The oil feeding line 2 and braking
The end of oil circuit 3 forms the connected state mutually crossed, the end concatenation pressure gauge 16 of the connection oil circuit by connecting oil circuit
With pressure sensor 17；Manual pump 9 is also associated with the oil feeding line 2, the manual pump 9 mutually and connects with gear pump 5；It is described
Also branch out to have to concatenate in two parallel branches, a parallel branch on overflow oil circuit, the overflow oil circuit on oil feeding line 2 and overflow
Flow concatenation cut-off ball valve 11 in valve 10, another parallel branch, the end connection fuel tank of the overflow oil circuit；The gear pump 5
Driven by Frequency Converter Control motor 6.
The motor 6 is common electric machine or variable-frequency motor.
Operation principle of the present utility model can be briefly described below.
When opening a sluice gate, flame proof reversing globe valve 12 obtains electric so that brake circuit 3 is closed, by Frequency Converter Control motor 6 with moving gear
The rotating speed of pump 5 is incrementally increased, and hydraulic oil sequentially passes through oil absorption filter 4, gear pump 5, high pressure filter 7, check valve 8 and overflow valve
10, default pressure is reached, oil cylinder 15 and accumulator 14 is finally reached, and pressure is shown by pressure gauge 16, oil cylinder 15 is transported
It is dynamic, promote the brake of disc type to declutch；Detect, reached after operating pressure through pressure sensor 17, the frequency converter manipulation low frequency of motor 6
Operating, the compensation conduit pressure loss coordinates holding to open a sluice gate state with accumulator 15；Whole process, the speed that oil pressure rises is by electricity
The rotating speed of machine 6 is controlled, and switching-off time is adjustable.
During braking brake, the dead electricity of flame proof reversing globe valve 12 causes brake circuit to open, and hydraulic oil is flowed back to by choke valve 13
Fuel tank 1, now motor 6 can be as needed with the small rotation speed operation of low frequency, the cooperation control band-type brake time of choke valve 13, if choke valve
13 unloadings are too fast, then the rotating speed of motor 6 somewhat increases, if choke valve 14 was unloaded slowly, and the rotating speed of motor 6 reduces or stalled.
When oil circuit breaks down, it can be suppressed by manual pump or end ball valve opening, realization is promptly opened a sluice gate or promptly embraced
Lock.
The part do not addressed in the utility model uses or used for reference prior art and can be achieved.
In description of the present utility model, it is to be understood that term " on ", " under ", "front", "rear", " horizontal stroke ", " vertical ",
The orientation or position relationship of the instruction such as " top ", " bottom " " interior ", " outer " be based on orientation shown in the drawings or position relationship, be only for
It is easy to description the utility model and simplifies describe, rather than to indicate or imply that signified device or element must have specific
Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.
Although more herein used the terms such as fuel tank 1, oil feeding line 2, brake circuit 3, it is not precluded from
