Detailed Description
For the purpose of further illustrating the principles and structure of the present invention, preferred embodiments of the invention will now be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 3, fig. 1 is a schematic top view illustrating a mounting device of a horn latch hook of an offshore floating type oil storage platform according to an embodiment of the present disclosure, fig. 2 is a cross-sectional view of A-A in fig. 1, and fig. 3 is a cross-sectional view of B-B in fig. 1. The mounting device 10 includes an indexing disk 11, the indexing disk 11 having a central bore 111.
Referring to fig. 4, which is a schematic structural diagram of a lock hook support plate and a flare in an embodiment of the disclosure, the flare 20 includes a flare 21 and a vertical barrel 22, the flare 21 is connected with the vertical barrel 22, and the flare 21 and the vertical barrel 22 form an included angle, which is a flare as a whole. The central hole 111 of the index plate 11 has a bore size in conformity with the outer diameter of the vertical tube portion 22 so that the central hole 111 can be inserted by the vertical tube portion 22.
The indexing disk 11 may be machined from 40mm thick steel plate. A plurality of groups of sliding grooves 112 are arranged on the dividing plate 11 at intervals, and the distribution position of each group of sliding grooves 112 on the dividing plate 11 is determined according to the distribution position of the locking hook supporting plate on the bell mouth. Each set of slide grooves 112 extends in the radial direction of the index plate 11. In a specific embodiment, the plurality of sets of sliding grooves 112 are equally spaced along the circumferential direction of the indexing disk 11. As shown in fig. 1, 10 groups of sliding grooves are distributed in the circumferential direction of the dividing plate 11, and the radian alpha of the interval between two adjacent groups of sliding grooves is 36 degrees. It will be appreciated that the number of sets of runners provided in the circumferential direction of the indexing disk 11 and the spacing distance between sets of runners may vary depending on the weight and size of the flare.
Referring to fig. 3 and 5, fig. 5 is a schematic perspective view of an index plate in an embodiment of the disclosure, each set of sliding grooves 112 includes two spaced sliding grooves 112, a boss 113 is disposed between the two sliding grooves 112, and each sliding groove 112 is correspondingly matched with a latch hook support plate 40. Each chute 112 includes a first slot 112a and a second slot 112b. The depth of the first clamping groove 112a is greater than the depth of the second clamping groove 112b. The first slot 112a has a smaller slot width than the second slot 112b. The sliding groove 112 is designed according to the structural design of the latch hook supporting plate 40, so that different latch slot positions can avoid interference of the latch hook supporting plate in the moving process.
Each set of runners 112 can position two shackle support plates 40. Referring to fig. 6 and 7, fig. 6 is a front view of a latch hook support plate according to an embodiment of the present disclosure, and fig. 7 is a top view of the latch hook support plate according to an embodiment of the present disclosure, a notch 41 is formed in the latch hook support plate 40, and a first mating portion 42 and a second mating portion 43 are disposed on two sides of the notch 41, respectively.

The first engaging portion 42 engages with the first engaging portion 112a, and the first engaging portion 42 engages with the first engaging portion 112a because the depth of the first engaging portion 112a is greater than the depth of the second engaging portion 112b, and is restricted to the first engaging portion 112a, and cannot move forward (i.e., move in the direction of the center hole of the index plate 11). As shown in fig. 7, the first engaging portion 42 and the second engaging portion 43 have a width difference d1, that is, the width of the first engaging portion 42 is smaller than the width of the second engaging portion 43, and correspondingly, the width of the first clamping groove 112a is smaller than the width of the second clamping groove 112b, and the groove width of the clamping groove limits the movement of the corresponding engaging portion in the left-right direction (i.e., the circumferential direction of the index plate).

The support edge 132 is formed in a ring shape, and is formed by protruding the bottom surface of the base 13 toward the hole axis direction of the mounting hole 131.
The base 13 is manufactured by machining a steel plate with the thickness of 45 mm. The wall of the mounting hole 131 of the base 13 is inclined so that the overall contour of the wall is tapered to facilitate insertion of the flare 20. In one embodiment, the inclination angle β of the hole wall is 6 degrees. It will be appreciated that in other embodiments, the angle of inclination of the aperture wall may be other angles to facilitate insertion of the flare 20.
In another embodiment, the mounting device 10 may omit the stiffener plate and base, in which case the indexing disk may rest directly on the support table with the circular recess. When the horn mouth is positioned, the horn mouth is inserted into the central hole of the index plate and the circular groove of the supporting table top, the horn mouth is supported by the supporting table top, and the depth of the circular groove is determined according to the specific position of the lock hook supporting plate at the horn mouth.

The mating plate 143 is located on the same side of the base 141 and the intermediate riser 142, and connects the base 141 and the intermediate riser 142 on the same side.
The two sides of the bottom surface of the base 141 are respectively provided with steps 1411, and the two steps 1411 are respectively matched with the two sliding grooves 112 of the same group and can move along the corresponding sliding grooves 112.
The middle riser 142 has a through hole 1421 in the middle to reduce the overall weight of the scribing tool 14.
The mating plate 143 includes a first mating surface 1431, a second mating surface 1433, and a connecting surface 1432 connecting the first mating surface 1431 and the second mating surface 1433. The first mating surface 1431, the second mating surface 1433 and the connecting surface 1432 form an included angle, so that the projection of the first mating surface 1431 on the bell mouth 20 coincides with the welding line of the locking hook support plate, and the projection of the second mating surface 1433 on the bell mouth 20 coincides with the contour of the mating groove 201.
Referring to fig. 11, which is a schematic diagram illustrating the matching between the scribing tool and the bell mouth in an embodiment of the disclosure, the scribing tool 14 slides along the chute 112 until the first matching surface 1431 and the second matching surface 1433 of the matching plate 143 contact the surface of the bell mouth 20, and the welding line of the latch hook support plate and the outline line of the matching groove 201 can be drawn along the outline scribing of the first matching surface 1431 and the second matching surface 1433. The welding line of the lock hook support plate is drawn on the horn mouth 20 in advance through the scribing tool 14, so that the subsequent lock hook support plates 40 are welded in place, the accuracy of the welding position of each lock hook support plate 40 is improved, the interference between the lock hook and the horn mouth 20 caused by the rotation and locking process of the lock hook is avoided, and the locking function of the lock hook 50 is influenced or the structure of the horn mouth 20 is damaged.
In addition, the horn mouth is scored through the scribing tool 14, so that the scribing precision and the scribing efficiency are improved, and the assembly efficiency of the lock hook support plate is improved.
