Description
Technical field
The utility model belongs to petroleum drilling technology field, and in particular to a kind of slush pump belt guard stoppage protection dress
It sets.
Background technology
Accidentally dismounting protective device is to prevent mud in oil drilling industry to the running belt guard of oil-well rig slush pump
Pump belt guard dismantles the safety convenience instrument for causing the accident or hurting sb.'s feelings.In oil drilling construction operation, since slush pump is transported
Belt guard in row accidentally dismounting and caused by accident or hurt sb.'s feelings happen occasionally.How the peace of oil-well rig mud pump operation is improved
Full property is always each oil field and drilling machine manufacturer focus of attention.
Currently, be provided to oil-well rig slush pump belt guard accidentally dismounting protection equipment usually will appear in operation with
Lower problem：It is severe due to environment, cause function simply to be protected and is easy failure.Even if effective in protection, because of it
Protective levels are few and cause reliability not high, also it occur frequently that belt guard accidentally make by dismounting in oil-well rig slush pump operational process
At equipment damage and personal injury situation.
Utility model content
The purpose of this utility model is to provide a kind of slush pump belt guard shutdown protector, is stopped with solving existing shield
Machine protective device is vulnerable, and the problem that reliability is not high.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of slush pump belt guard shutdown protector, including shield and shield bottom is fixed at by screw
Holder III is arranged on the side wall of shield in shield pedestal, setting holder I and holder II on shield pedestal；The top setting pressure of holder I
Force snesor, pressure sensor are equipped with compression rod；Obliquity sensor, the bottom surface of holder III and compression are horizontally disposed on holder III
Bar contacts；Range sensor is arranged in the top of holder II, and range sensor is set in the orthographic projection of holder III；The pressure sensing
Device, obliquity sensor and range sensor are connected by circuit with the PLC being set on shield pedestal respectively, PLC and setting
Audible-visual annunciator outside shield is connected.
The audible-visual annunciator is set on holder III.
The output signal of the pressure sensor, obliquity sensor and range sensor is 4-20mA.
The range sensor is ligh-ranging sensor.
The utility model having the beneficial effect that compared to the prior art：
The utility model forms three-level detection using multiple sensors, pre- under shield difference disassembly status to realize
Alert and protection, flexible given threshold provide best alarm and safeguard measure；The device can work independently, also can be with other prisons
System synergistic working is controlled, realizes belt guard accidentally dismounting three-level stoppage protection automation in oil-well rig mud pump operation.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Reference numeral meaning is as follows：1, shield pedestal；2, holder I；3, holder II；4, shield；5, holder III；6, pressure passes
Sensor；7, compression rod；8, obliquity sensor；9, range sensor；10、PLC；11, audible-visual annunciator.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of slush pump belt guard shutdown protector, including shield and it is fixed at by screw
Holder III 5 is arranged on the side wall of shield 4 in the shield pedestal of shield bottom, setting holder I 2 and holder II 3 on shield pedestal 1；Branch
Pressure sensor 6 is arranged in the top of frame I 2, and pressure sensor 6 is equipped with compression rod 7；Inclination angle sensing is horizontally disposed on holder III 5
The bottom surface of device 8, holder III 5 is contacted with compression rod 7；Range sensor 9 is arranged in the top of holder II 3, and range sensor 9 is flash ranging
Away from sensor.Range sensor 9 is set in the orthographic projection of holder III 5；Pressure sensor 6, obliquity sensor 8 and range sensor
9 are connected by circuit with the PLC10 being set on shield pedestal 1 respectively, and PLC10 is connected with audible-visual annunciator 11.
The audible-visual annunciator 11 can be set on holder III.
The output signal of the pressure sensor 6, obliquity sensor 8 and range sensor 9 is 4-20mA.
When the utility model operation, 6 output signal of pressure sensor is that 4mA is zero pressure, i.e. compression rod 7 and holder III
5 is contactless, indicates that the nut of 4 fixing screws of shield is separated, the pressure between shield 4 and shield pedestal 1 is zero；Work as output signal
To be normal pressure when 20mA, i.e., compression rod 7 is compressed by holder III 5, indicates shield 4 and the installation fastening of shield pedestal 1, fixed spiral shell
Non-loosening is followed closely, centre is linear correspondence, and pressure signal is transmitted to PLC10, can drive audible-visual annunciator 11 after processing
Low frequency and low decibel sound-light alarm are done, warning protective cover 4, which is fixed, loosens or have dismounting.
Indicate that the angle between shield 4 and holder III 5 is -30 degree when 8 output signal of obliquity sensor is 4mA；When 20mA
Indicate that the angle between shield 4 and holder III 5 is 30 degree；Indicate that the angle between shield 4 and holder III 5 is 0 degree when 12mA, this
When shield 4 be in without the normal condition of shifting is torn open, dip angle signal is transmitted to PLC10, after processing can given threshold, it is out-of-limit, drive
Audible-visual annunciator 11 does intermediate frequency and compared with high-decibel sound-light alarm, and warning protective cover 4, which tears shifting open, to be started, while PLC10 output signals
Belt is set to reduce speed now.
9 ligh-ranging sensor of range sensor, the bottom surface back reflection of transmitting light source to holder III 5 returns Distance-sensing when operation
Device 9 completes range measurement, when the output signal of range sensor 9 is 4mA, the displacement setting between shield 4 and shield pedestal 1
It is zero, when output signal is 20mA in dismounting, shield 4 is 300mm with 1 split displacement of shield pedestal, i.e., shield 4 is from shield
It is separated on pedestal 1, distance signal transmission to PLC, output signal makes relevant device implementation belt shut down after processing, simultaneously
Audible-visual annunciator 11 is driven to alarm.
