Oil pipe A, and then oil pipe A length is obtained accordingly, it is very convenient, and oil pipe length measuring device does not have any part to be installed on well
Mouth drops in oil well, is not influenceed by well head situation and measures accurate.
In the present embodiment, the value of thrust measured according to pull force calculation part 20 judges whether lifting mechanism 10 hangs load oil pipe A tools
Body is：When the pulling force detected is gradually increased until stable pre set force from 0, illustrate that lifting mechanism 10 starts to hang load oil pipe,
When the pulling force detected gradually decreases to 0 from a stable pre set force, illustrate that lifting mechanism 10 starts to unload oil pipe, by
This judges whether lifting mechanism 10 hangs load oil pipe A.
Specifically, pulling force detector can be pulling force sensor.
In the present embodiment, surveying long part 30 includes angle detector and multiplier, turn of angle detector detection reel 102
Angle, and multiplier is sent to, multiplier obtains steel wire rope 104 according to the corner of reel 102 and the diameter of of reel 102 itself
Rope closing or rope stretching length, and then obtain the displacement of suspension hook.It is appreciated that angle detector can be angular transducer, coding
Device.Angle detector may also comprise proximity switch, angle route marker and the trigger located at reel 102 located at fuselage 100,

And angle route marker is sent to, the signal that angle route marker is sent according to proximity switch obtains the corner of reel 102.For example, volume
Cylinder 102 often sends one-time detection to trigger provided with a trigger, fuselage 100 provided with a proximity switch, proximity switch
Signal instruction reel 102 make a circle, that is, turned 360 degree.
More specifically, surveying the multiple tooth flywheel that long part 30 also includes being coaxially disposed with reel 102, proximity switch correspondence is multiple tooth to fly
Take turns and set.Multiple tooth flywheel has n tooth, and the angle between every two neighboring tooth is 360/n °, when proximity switch successively sends two
Signal, illustrates that reel 102 has turned over 360/n °, the like.More specifically, the quantity of proximity switch is two, so can be with
Differentiate the rotation direction of reel 102.
In the present embodiment, the pulling force that the acquisition steel wire rope 104 of pull force calculation part 20 is born can obtain the bearing capacity of suspension hook.Such as
Shown in Fig. 2, when oil pipe A needs down tube, in the first state, suspension hook is in higher position, and oil pipe A is located above oil well,
Oil pipe A end is hung on suspension hook, at this moment, by the oil pipe B seats of another oil pipe B connection of oil pipe A and lower section, now lower section
At wellhead slip, hoisting mechanism does not stress, and at this moment controller 50 can determine whether that oil pipe A is in the state for beginning preparing for declining；Even
Rear hoisting mechanism work is connected, oil pipe A and another oil pipe of lower section are connected, the bearing capacity of suspension hook is gradually increased until surely from 0
Fixed, the pulling force correspondence that pull force calculation part 20 is measured is gradually increased to a stable value from 0；Then suspension hook is gradually reduced, and is declined
During to the second state, the bearing capacity of suspension hook is gradually reduced until 0 from stable, and the pulling force correspondence that pull force calculation part 20 is measured is from one
Stationary value gradually decreases to 0, and oil pipe A is sitting at wellhead slip, and at this moment controller 50 can determine whether that oil pipe A has dropped to position；Meanwhile,
In this time, the displacement L that long part 30 measures suspension hook is surveyed, this is oil pipe A decentralization apart from L or rises depth.Can be with
Understand, principle is identical when playing pipe.Specifically, the one end of steel wire rope 104 is located at driver's cabin front end, is then set around crane arm top
Wheel is simultaneously connected with suspension hook, then around being set on reel 102.
In the present embodiment, controller 50 also includes adder, and adder is by the decentralization of each oil pipe of acquisition or rises depth
Plus and total decentralization of multiple-tubing string for entirely being linked together or rise depth.It should be noted that due to two neighboring
Needed between oil pipe connect certain distance, that is, oil pipe total decentralization or rise depth and be not equal to the overall length of all oil pipes
, there is error in degree, and easily there is error during due to connection if be directly added each tubing length, subtract even from experience
Fall the length of connection, can also there is error.The decentralization of each oil pipe of the utility model direct measurement rises depth, in the absence of above-mentioned
Error, it is more accurate to measure.

Device 50 is connected, for showing tubing length or manually compensating the man-machine interactions such as input.
The utility model also provides a kind of tubing length that tubing length is measured using above-mentioned oil pipe length measuring device
Measuring method, comprises the following steps：
S12：Oil pipe A is mounted on lifting mechanism 10 and lifted by crane, while detecting the oil pipe A applications that lifting mechanism 10 is carried
Pulling force；
S14：Tension variations situation according to detecting judges whether lifting mechanism 10 hangs load oil pipe A；
S16：Measure the oil pipe A distances that oil pipe A is moved during lifting；
S18：The distance acquisition oil pipe A of the information for carrying oil pipe A and oil pipe A movements decentralization whether is hung according to lifting mechanism 10
Or rise depth.
The value of thrust that this oil pipe length measuring method detection oil pipe applies is that can determine whether whether lifting mechanism 10 hangs load oil pipe,
And then oil pipe A length is obtained accordingly, it is very convenient, and any part need not be installed in well head or dropped in oil well, no
Influenceed by well head situation and measure accurate.
Specifically, step S14 is specially：When the pulling force detected is gradually increased until stable from 0, lifting mechanism 10 is opened
Beginning hangs load oil pipe, when the pulling force detected gradually decreases to 0 from a stationary value, and lifting mechanism 10 starts to unload oil pipe, by
This judges whether lifting mechanism 10 hangs load oil pipe A.
In the present embodiment, oil pipe length measuring method also includes step：
S20：The multiple-tubing string A entirely linked together according to the decentralization of each oil pipe of acquisition or rising depth calculation
Total decentralization or rise depth.
