When to be often hard to tell let out in balanced valve failure or oil cylinder on earth, once get wrong, or without finding to let out in oil cylinder in time,
It is light then delay the duration, it is heavy then cause serious accident.Therefore, it is proposed that letting out online inspection in a kind of rotary drilling rig hydraulic jack
Survey device.
Utility model content
The purpose of this utility model, which is to provide in a kind of rotary drilling rig hydraulic jack, lets out on-line measuring device, with solution
State proposed in background technology because seal is inside oil cylinder, do not see, can not touch, failure is not easy to discover, and hydraulic oil
After cylinder driving pinned by balanced valve, and the phenomenon of the failure let out in the phenomenon of the failure of balanced valve and oil cylinder is with greatly similar
Property, being often hard to tell when failure is investigated is let out in balanced valve failure or oil cylinder on earth, once get wrong, or without timely
It was found that being let out in oil cylinder, gently then delay the duration, it is heavy then the problem of cause serious accident.
To achieve the above object, the utility model provides following technical scheme：Let out in a kind of rotary drilling rig hydraulic jack
Line detector, including balanced valve and hydraulic jack, the top left and right sides of the balanced valve are connected to by petroleum pipeline
Small chamber flow sensor and big chamber flow sensor, the top of the small chamber flow sensor are connected to the liquid by petroleum pipeline
The left side top of compressing cylinder, the top of the big chamber flow sensor is connected to the right side bottom of the hydraulic jack by petroleum pipeline
Portion.
It is preferred that, the balanced valve is Bidirectional balanced valve.
It is preferred that, the bottom left and right sides of the balanced valve is respectively arranged with the first oil inlet and the second oil inlet.
It is preferred that, the big chamber flow sensor and small chamber flow sensor are turbine type flow sensor.
Compared with prior art, the beneficial effects of the utility model are：The utility model works as hydraulic oil cylinder driving system drive liquid
When pressing oil cylinder working, if oil cylinder is let out without interior, the flow on flow and the small chamber passage of oil cylinder on the big chamber driving passage of oil cylinder
The ratio between should be certain value under certain pressure difference, once oil cylinder occur in let out, this ratio will change, and due to flow
Sensor is located between balanced valve and oil cylinder, eliminates the interference of balanced valve failure, therefore, logical by comparing the big chamber driving of oil cylinder
On road on flow and the small chamber passage of oil cylinder flow ratio, it is possible to it is accurate to judge whether hydraulic jack occurs interior let out；This practicality
It is new by setting flow sensor between balanced valve and hydraulic jack, realize to being let out in rotary drilling rig hydraulic jack
Line is monitored, and improves the security of rotary drilling rig construction.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
In figure：1 balanced valve, 2 big chamber flow sensors, 3 small chamber flow sensors, 4 hydraulic jacks.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：On-line checking is let out in a kind of rotary drilling rig hydraulic jack
Device, including balanced valve 1 and hydraulic jack 4, the top left and right sides of the balanced valve 1 is connected to small chamber by petroleum pipeline
Flow sensor 3 and big chamber flow sensor 2, the top of the small chamber flow sensor 3 are connected to the liquid by petroleum pipeline
The left side top of compressing cylinder 4, the top of the big chamber flow sensor 2 is connected to the right side of the hydraulic jack 4 by petroleum pipeline
Side bottom.
Wherein, the balanced valve 1 is Bidirectional balanced valve, and Bidirectional balanced valve can be easy to control oil supply loop, the balance
The bottom left and right sides of valve 1 is respectively arranged with the first oil inlet and the second oil inlet, when rotary drilling rig hydraulic system is from balanced valve 1
The first oil inlet or the second oil inlet fuel feeding when, you can driving hydraulic jack 4 act, the first oil inlet oil-feed, the second oil-feed
Mouth is oil return, otherwise the second oil inlet oil-feed then the first oil inlet oil return, forms loop, the big chamber flow sensor 2 and small
Chamber flow sensor 3 is turbine type flow sensor, and turbine type flow sensor is a kind of delicate flow measuring instrumentss, with phase
The supporting flow and total amount that can be used for measuring liquid of flow totalizer meter answered.
Operation principle：On-line measuring device is let out in a kind of rotary drilling rig hydraulic jack, including balanced valve 1, big chamber flow are passed
Sensor 2, small chamber flow sensor 3 and hydraulic jack 4, set flow sensor, big chamber between balanced valve 1 and hydraulic jack 4
Flow sensor 2 is arranged on the big chamber of hydraulic jack 4 driving passage, and small chamber flow sensor 3 is arranged on the small of hydraulic jack 4
On chamber driving passage, let out in rotary drilling rig hydraulic jack in on-line measuring device, when rotary drilling rig hydraulic system is from balanced valve 1
The first oil inlet or the second oil inlet fuel feeding when, you can driving hydraulic jack 4 act, the first oil inlet oil-feed, the second oil-feed
Mouth is oil return, otherwise the second oil inlet oil-feed then the first oil inlet oil return, forms loop, is at this moment arranged on the big chamber of hydraulic jack 4
Big chamber flow sensor 2 and 3 pairs of small chamber flow sensor being arranged on the small chamber of hydraulic jack 4 driving passage on driving passage
The fact that on loop, flow was counted, if oil cylinder is let out without interior, large and small chamber drives the flow available hydraulic oil cylinder on passage
The volume of the unit interval of 4 large and small chambers changes to represent, i.e., the flow Q1=S1L of big chamber flow sensor 2, and low discharge is passed
The flow Q2=S2L of sensor 3, wherein S1 are the big chamber active area of hydraulic jack 4, and S2 acts on for the small chamber of hydraulic jack 4
Area, L is the stroke of the hydraulic jack 4 in the unit time, so, flow Q1 and the low discharge sensing of big chamber flow sensor 2
The ratio between flow Q2 of device 3：Q1/Q2=S1/S2, i.e., be directly proportional to the large and small chamber active area of hydraulic jack 4, and large and small chamber is acted on
Area is definite value, i.e., the ratio is also definite value, is let out when in oil cylinder generation, the flow of the flow sensor on drainback passage is not only
It is the volume change in the unit interval, should also adds leakage rate, ratio will changes, and therefore, pass through electrical system control device
The large and small chamber section ratio of the ratio between reading of big chamber flow sensor 2 and rill quantity sensor 3 and hydraulic jack 4 is entered in real time
Row compares, and can monitor whether hydraulic jack 4 is interior to be let out in real time, and flow sensor is located between balanced valve 1 and hydraulic jack 4,
What the reading of flow sensor reflected is the flow on the large and small chamber of hydraulic jack 4 driving passage, unrelated with balanced valve 1, is eliminated
The interference of the failure of balanced valve 1.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
