Specific embodiment
The utility model is described in detail in each embodiment shown in reference to the accompanying drawing, but it should be stated that,
These embodiments are not limitation of the utility model, those of ordinary skill in the art according to these embodiments made by function
Energy, method or equivalent transformation or substitution in structure, belong within the protection scope of the utility model.
As shown in Figure 1, a kind of positioning device being installed on hull, including the first (top GPS being installed at the top of loop wheel machine
GPS), being extended at the top of the loop wheel machine has hoist cable, the scanner and dipmeter being installed on hull, further includes being located at hull
On the 2nd GPS and the 3rd GPS；2nd GPS and the 3rd GPS is used to measure the position of current hull, and described first
GPS is for measuring hoist cable top position；The scanner is installed on the edge of the central area of hull, and the scanner is swept
Retouch the working region of hoist cable described in range face.
From diagram as can be seen that above-mentioned scanner uses noctovisor scan instrument, noctovisor scan instrument is the pass in this system
Key instrument, the data accuracy obtained can be the key techniques of this system.In idealized model, noctovisor scan instrument is logical
Over-angle and distance parameter obtain all objects coordinate in range, and taking its average is the space coordinate B of wire sling.
Angular range: with scanner central axes for 0 degree, being up to the right 95 degree, minimum to -95 degree to the left.It please input and sweep
It surveys target place substantially angular range and quickly identifies target so that software screens out other objects.
Distance range: the approximate distance at input target range scanner center is quickly known so that software screens out other objects
Other target.
Sweep survey precision: sweeping and surveying target is wirerope (hoist cable has more wirerope), and has more, sweeps survey so to input
Precision, so that software calculates the center of more wirerope.
Specifically the signal datas such as 3 GPS, dipmeter, noctovisor scan instruments are transmitted to control room terminal by data line
Computer.Various winding displacements and serial ports construct communication system, and communication signal quality is more preferable, in the construction environment of waters stability compared with
It is good.
Referring to shown in Fig. 2, special gravity bob 900, top are welded in the 3rd GPS 1000 (top GPS) installation, loop wheel machine top
The installation exquisiteness screw thread of reserved GPS receiver guarantees that GPS receiver is in plummet state always, and the coordinate A of acquisition is more smart
Really.
Referring to described in Fig. 3, exposed throughout type hexahedron passes through hoist cable and lifts into water, measures the hoist cable top by positioning system
The GPS coordinate in portion is set as A (X1, Y1, Z1).
After being put under water by the exposed throughout type hexahedron that hoist cable lifts, due to the flow effect of water flow, exposed throughout type hexahedron
Position be continually changing, therefore need further a variety of instruments accordingly measured, specifically: noctovisor scan instrument itself
Coordinate determines its coordinate (X2, Y2, Z2) by dipmeter by the positional relationship corresponding thereto of two GPS1, GPS2 on ship；
Scanner sweep survey front horizontal direction hoist cable, by setting sweep survey range in hoist cable wirerope coordinate relative position (l1, α 1~
Ln, α n) whole incoming computers, be ultimately converted to multiple plane coordinates, take its average value, obtain hoist cable B point coordinate (X3, Y3,
Z3)。
Then the extended line of coordinate A and coordinate B and the tie point of exposed throughout type hexahedron central point are that exposed throughout type is hexahedral
Coordinate C, therefore need to only know installation site elevation Z4, computer can pass through coordinate A (X1, Y1, Z1) and coordinate B (X3, Y3, Z3)
Extrapolate the plane coordinates (X4, Y4) of C.
Referring to described in Fig. 4, for 900 fixing assembling of gravity bob in mounting base, the gravity bob includes gravity bob ontology 910,
The installation part 911 of 910 affixed first GPS in top of gravity bob ontology, the gravity bob body lower part 914 are fixed in the peace
It fills on seat 912, further includes the fixing axle 913 for running through gravity bob ontology and being welded in mounting base.
Mounting base 912 includes mounting seat body 9121, and the fixed plate 9122 extended to form by the mounting seat body is described
The top of fixed plate is symmetrically arranged with guard bar 9123, and the two sides of the fixing axle 913 are fixed in the fixed plate 9122.
One end of the installation part 911 is anchored on the gravity bob ontology 910, and the other end is arranged screw thread 913, and described the
One GPS is assemblied on the gravity bob ontology by screw thread rotation.
Further, dipmeter is close to the 2nd GPS, and dipmeter mainly measures the integral inclined degree of hull, therefore close to
2nd GPS, so that the coordinate instantly of hull and the tilt coordinates of hull, two measurement of coordinates whens, locating environment was identical
's.
And the first GPS is located at stern, the 2nd GPS and the 3rd GPS are located at fore.Wherein the first GPS is mainly used for surveying
Position fixing A, the 2nd GPS and the 3rd GPS close on, the main coordinate instantly for measuring hull, by the first GPS and the 2nd GPS, third
GPS is separate, and anti-stop signal is interfered, and causes the deviation of coordinate parameters.
In addition hanger is connected with by hoist cable below loop wheel machine, the hanger is for clamping exposed throughout type hexahedron, inoperative shape
The suspender and the first GPS are located on same axis when state.
Referring to Figure 5, a kind of for lifting the hexahedral hanger of exposed throughout type, including symmetrically arranged fixture 700, it is described
Fixture 700 includes chuck body 710, and the chuck body includes upper linking arm 7101 and lower clamping limb 7102, the upper company
