Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without creative efforts
All other embodiments obtained shall fall within the protection scope of the present invention.
Embodiment：As shown in Fig. 1-7.Derrick crane hoisting operation three-dimensional coordinate real-time measurement apparatus, including main lifting
Disk 1, secondary lifting disk 2, pedestal 3, hook 4 and wire rope roll device 5, the wire rope roll device 5 is by position-arresting disk 6,7 and of rotating bar
Stainless steel wire rope 9 forms；It is characterized in that：The main lifting disk 1 is internally provided with the secondary lifting disk 2 with its concentric, and master hangs
Sabot 1 on secondary lifting disk 2 with being equipped with the location hole 11 of the mutual center of circle point-blank；11 inside of location hole is
Equipped with bearing 8, and wire rope roll is equipped with by bearing 8 and the interference fit of rotating bar 7 between main lifting disk 1 and secondary lifting disk 2
Device 5；One end of rotating bar 7 on the secondary lifting disk 2 extends to the inside of secondary lifting disk 2, and extends in secondary lifting disk 2
One end of the rotating bar 7 in portion is fixed with stay wire displacement sensor 10；Main lift is equipped with pedestal 3 on disk 1, solid on pedestal 3
Surely there is hook 4.
The internal diameter of the main lifting disk 1 is twice of secondary lifting 2 outer diameter of disk.The main lifting disk 1 of the utility model and secondary lifting
What is installed between disk 2 is wire rope roll device 5, forms and is wrapped in the rotating bar 7 of wire rope roll device 5 for hoisting object
Steel wire rope, the pulling force having on steel wire rope is mainly born by rotating bar 7, and the power that rotating bar 7 is born is finally to be transferred to master
On lifting disk 1 and pair lifting disk 2, therefore uniformly shared in order to enable being applied to main lifting disk 1 and the secondary power for lifting disk 2,
The effect that main lifting disk 1 and secondary lifting disk 2 are played is considered simultaneously, therefore it is secondary to require the main internal diameter for lifting disk 1 in design
Lift twice of 2 outer diameter of disk.
The main lifting disk 1 is threadedly coupled with pedestal 3.The utility model is played to hold during entire lifting operation and be opened
Under effect, crane 15 lifted by crane by lifting boom 14, and lifting boom 14 drives main rope 13 to complete lifting operation；Main rope
Power on 13 passes to pedestal 3 by hook, requires pedestal 3 and master in design at this time in order to ensure the continuity of power transmission
Lifting disk 1 should be integral, while it is also contemplated that convenient wire rope roll device 5 and bracing wire displacement in main lifting disk 1 passes
Sensor 10 is replaced or is repaired, therefore main lifting disk 1 is connected through a screw thread with pedestal 3 makes winner's lifting disk 1 be realized with pedestal 3
Free separation and assembling.
The main lifting disk 1 is three, and pore size is consistent with 11 numbers of location hole on secondary lifting disk 2；It is described
Location hole 11 on main lifting disk 1 lifts the center of circle of the location hole 11 on disk 2 with pair point-blank.The utility model is
It is designed to measure by position of the lifting cargo in three-dimensional system of coordinate (space), it is known that being existed by lifting cargo in practice
The position of three-dimensional system of coordinate determines by three points of x, y, z, and can be influenced by various factors in lifting by lifting cargo and
Position is caused to change at any time, real time position just seems highly difficult in space by lifting cargo so to measure.Thus this practicality
It is novel to consider that stay wire displacement sensor 10 has the characteristics that " using winding wheel perimeter metering object length distance " in the design
It is realized with being combined for the wire rope roll device 5 of hoisting object to the steel after being discharged from wire rope roll device 5 again
The length of cord measures.Stay wire displacement sensor 10 is BEN stay wire displacement sensors in the utility model, it is exhausted by BEN
Encoder (not shown) and stainless steel wire rope (not shown) are formed, and one end of the stainless steel wire rope and stainless steel
Cord 9 connects, and the other end is wrapped in threaded wheel hub (not shown), wheel hub connection BEN absolute encoders, and
BEN absolute encoders are made of code-disc and photoelectric detection system；Code-disc (grating disc) be on the plectane of certain diameter partially
Open several slots.Since stay wire displacement sensor 10 is fixedly mounted on the rotating bar 7 of composition wire rope roll device 5
One end, therefore when wire rope roll device 5 rotates, code-disc (grating disc) rotates at the same speed with rotating bar 7, in 7 rotation process of rotating bar
The stainless steel wire rope 9 of winding on it is released, since the inside code value of BEN absolute encoders has been set, therefore rotating bar 7
Drive stay wire displacement sensor 10 represents the code value of the circle output of encoder one once having enclosed multi-turn, passes through changing for code value
The stainless steel wire rope 9 wound on it into 7 rotation process of rotating bar is released length.It is measured by stay wire displacement sensor 10
The obtained length of stainless steel wire rope 9 by the length L1 of steel wire rope A, the length L2 of steel wire rope B and steel wire rope C length L3 groups
Into, the one ends wound of steel wire rope A, steel wire rope B and steel wire rope C in the rotating bar 7 for forming wire rope roll device 5, and they
The other end is separately fixed at by three different locations in hoisting object 12, is obtained in this way in practical hoisting process with regard to measuring
The length L3 of the length L1 of steel wire rope A, the length L2 of steel wire rope B and steel wire rope C.
Mechanical displacement is converted into measurable, linearly by the utility model using stay wire displacement sensor 10
Electric signal.When tested lifting cargo 12 generates displacement, coupled steel wire rope A, steel wire rope B and steel wire rope C are pulled,
Steel wire rope A, steel wire rope B and steel wire rope C drive rotating bar 7 to rotate at this time, and the rotation of rotating bar 7 drives the drawing being connect with rotating bar 7
Linear movement pick-up 10 rotates synchronously；When movement occurs, steel wire rope stretches and stretches, and threaded wheel hub drives BEN absolutely to compile
Code device rotation, exports an electric signal proportional to drawstring displacement distance, is obtained so as to be measured in practical hoisting process
The length L3 of the length L1 of steel wire rope A, the length L2 of steel wire rope B and steel wire rope C.Then coordinate system as shown in Figure 1 is established, wherein
(x, y, z) be the coordinate of object to be measured in a coordinate system, point A (x1,y1,z1)、B(x2,y2,z2), C (x3,y3,z3) be
Fixed point in three reference axis, therefore the coordinate of three points can further be write as：A(0,0,z1)、B(x2,0,0)、C(0,
y3,0).There is distance l of the object under test to three points in this way1、l2、l3Expression formula be respectively：
Substitute into A (0,0, z1)、B(x2,0,0)、C(0,y3, 0) have：
In practical operation, for reduced mechanical model, z is taken1=x2=y3=1, such above formula (2) can using abbreviation as：
It enables
(3)-(4)
(3)-(5)
(6), (7) substitute into (3) and obtain
Expansion arranges above formula：
3z2+2(2a-b-c-1)z+2a2-2a(b+c+1)+b2+c2+ 1=0 (9)
It can be solved by formula (9)：
(10) (6) are substituted into obtain：
