Description

Winch interlock valve inhibiting device
Technical field
The utility model relates to a kind of mining device, relates in particular to a kind of winch interlock valve inhibiting device.
Background technology
Interlocked valve is an important component part of the quick adjusting rope device of double drum hoist oil pressure gear type, is to prevent the external gear mechanical locking device that outwards engagement mobile and disengagement inner gear causes the accident when normal operation.
It is fatal that the inside and outside gear of operating double drum hoist adjusting rope device is surprisingly thrown off security threat.After disengaging in service, the heavy lack of equilibrium effect immediately of extension of two reels of equidirectional operation, one of them reel therefore extension on reel limit heavily impels and rotates backward, another reel therefore extension on limit weighs and accelerates forward to rotate, even if now pinpoint the problems, system is taked promptly to execute lock measure, also be that It dones't help the situation, because it is excessive that the extension of each monolateral reel remakes into monotubular Tension Difference, in addition be again in dynamic operation, even if the drg on each reel limit is normally executed lock also because of lock torque wretched insufficiency, cause each reel driving in the same way, cause a serious accident.
Summary of the invention
The purpose of this utility model is to provide a kind of safe winch interlock valve inhibiting device that uses.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of winch interlock valve inhibiting device, comprise valve body, in valve body, have oil pocket, oil pocket one end is with installing port, the oil pocket other end has telescopic mouth, the internal diameter of telescopic mouth is less than the internal diameter of installing port, in valve body, also have the first oil circuit and the second oil circuit, the first oil circuit and the second oil circuit communicate with oil pocket is airtight respectively, it is characterized in that: in oil pocket, slidably connect piston pin, piston pin wherein one end inwardly offers pit, the piston pin other end is fixedly connected with ejector pin, ejector pin and piston pin are structure as a whole, the ejector pin other end extend out in wheel hub from telescopic mouth, ejector pin and telescopic mouth are sliding block joint, the installing port place plug screw that has been threaded, plug screw negative thread is connected with jackscrew, and jackscrew inner end apical grafting is in pit.
According to described winch interlock valve inhibiting device, it is characterized in that: airtight the 2nd O type circle that is fixedly connected with of described oil pocket inwall, the airtight O type circle that is fixedly connected with of described telescopic mouth inwall.
According to described winch interlock valve inhibiting device, it is characterized in that: the described jackscrew between described plug screw and described piston pin is set with spring outward.
According to described winch interlock valve inhibiting device, it is characterized in that: described valve body is fixedly connected with reaction plate, on reaction plate, offer fixed orifice.
The utility model increases plug screw length, makes plug screw screw in part and lengthens, and the predetermincd tension of Compress Spring is reliably absorbed in the wheel hub of cylinder piston pin, therefore can prevent that interlocked valve fault interlock pin unlatching in service from causing the accident, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing:
1, plug screw; 2, jackscrew; 3, pit; 4, spring; 5, piston pin; 6, the first oil circuit; 7, the second oil circuit; 8, valve body; 9, oil pocket; 10, ejector pin; 11, wheel hub; 12, an O type circle; 13, reaction plate; 14, fixed orifice; 15, the 2nd O type circle.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of winch interlock valve inhibiting device, as shown in Figure 1, comprise valve body 8, in valve body 8, have oil pocket 9, oil pocket 9 one end are with installing port, oil pocket 9 other ends have telescopic mouth, the internal diameter of telescopic mouth is less than the internal diameter of installing port, in valve body 8, also have the first oil circuit 6 and the second oil circuit 7, the first oil circuit 6 and the second oil circuit 7 communicate with oil pocket 9 is airtight respectively, in oil pocket 9, slidably connect piston pin 5, piston pin 5 wherein one end inwardly offers pit 3, piston pin 5 other ends are fixedly connected with ejector pin 10, ejector pin 10 is structure as a whole with piston pin 5, ejector pin 10 other ends extend out in wheel hub 11 from telescopic mouth, ejector pin 10 is sliding block joint with telescopic mouth, the installing port place plug screw 1 that has been threaded, plug screw 1 negative thread is connected with jackscrew 2, and jackscrew 2 inner end apical graftings are in pit 3.
In the present embodiment, airtight the 2nd O type circle 15 that is fixedly connected with of described oil pocket 9 inwalls, the airtight O type circle 12 that is fixedly connected with of described telescopic mouth inwall.The outer spring 4 that is set with of described jackscrew 2 between described plug screw 1 and described piston pin 5.Described valve body 8 is fixedly connected with reaction plate 13, offers fixed orifice 14 on reaction plate 13.
