and S1, placing the net cage frame on a plurality of moulding beds.
Specifically, each bottom beam 12 of the net cage frame is provided with a plurality of jig frames at intervals along the length direction thereof. The bed frame supports the bottom beam 12, so that the deflection change of the bottom beam 12 is reduced, and the precision control difficulty of the netting tool is reduced.

In the present embodiment, referring to fig. 4, the horizontal presetting point on the top support beam 21 is the center point of the bell mouth 211 on the top support beam 21. Referring to fig. 3, the vertical pre-set point on the top support beam 21 is the upper surface of the upper horizontal section of the top support beam 21.

Specifically in this embodiment, the first longitudinal spacing deviation is ± 5mm, the first longitudinal length deviation is ± 5mm, the first lateral deviation is ± 5mm, and the first vertical deviation is ± 3 mm.
Specifically, the top beam 11 is a rolled pipe, and due to a problem of machining accuracy, it is difficult to ensure ovality, coaxiality, and the like, so that the cross section of the top beam 11 is not a perfect circle, and the roundness of each section of the top beam 11 is also different, and therefore when each top support beam 21 is sleeved, a phenomenon that the first deviation requirement cannot be met between the top support beam 21 and the top beam 11 exists. At this time, the precision is controlled by grinding the sidewalls of the vias of the top support beam 21.
During polishing, two symmetrical points on the peripheral wall of the via hole are selected for polishing, so that the precision of the top support beam 21 is controlled within a first deviation range. For example, points a and B in fig. 3. The maximum depth and length of sanding is determined by the specific dimensions of the top support beam 21.

S6, pre-attaching a plurality of bottom support beams 22 to the bottom beams 12 of the cage frame with the deviation between the actual pre-attachment position of the bottom support beams 22 and the second pre-set position being within a first deviation range.
When the bottom support beams 22 on each bottom beam 12 are installed, the longitudinal direction of the bottom beam 12 is taken as the longitudinal direction, the width direction is taken as the transverse width, and the height direction is taken as the vertical direction.
Specifically, in the present embodiment, the pre-connection is achieved by spot welding.
Wherein the second preset position satisfies the following condition:
the bottom support beams 22 are installed from the center of the bottom beam 12 in the length direction to both ends, and the distance between two adjacent bottom support beams 22 is a second preset longitudinal interval. The distance between the bottom support beam 22 at one end of the bottom beam 12 and the upright 13 at the other end of the bottom beam 12 is a second predetermined longitudinal length. The distance between the predetermined lateral distance on the bottom support beam 22 and the central lateral point of the bottom beam 12 is a second predetermined lateral distance. The distance between the vertical preset point on the bottom support beam 22 and the caisson deck baseline of the deepwater net cage is a second preset vertical distance.
In the present embodiment, the horizontal preset point and the vertical preset point on the bottom support beam 22 are determined according to actual situations.
The second preset longitudinal interval, the second preset longitudinal length, the second preset transverse distance and the second preset vertical distance are specifically designed according to actual conditions such as the weight of the netting 3.

Specifically in this embodiment, the first longitudinal spacing deviation is ± 5mm, the first longitudinal length deviation is ± 5mm, the first lateral deviation is ± 5mm, and the first vertical deviation is ± 3 mm.
Specifically, during the pre-connection process, due to the machining accuracy of the bottom beam 12, the bottom support beam 22 may not meet the first deviation requirement during the pre-connection process with the bottom beam 12, and at this time, the end surface of the bottom support beam 22 connected with the bottom beam 12 is polished.
During polishing, two symmetrical points on the end surface of the bottom support beam 22 are selected for polishing, so that the precision of the bottom support beam 22 is controlled within a first deviation range.
And S7, welding and fixing the bottom support beam 22 on the bottom beam 12, and controlling the deviation between the actual fixing position of the bottom support beam 22 and the second preset position within the second deviation range, and the position deviation between the bottom support beam 22 and the top support beam 21 corresponding to the bottom support beam within the preset deviation range.
The second preset position and the second deviation can be referred to the above, and are not described in detail herein.
The bottom support beam 22 is controlled to have a twist deformation of less than 10mm in the longitudinal direction and a twist deformation of less than 10mm in the transverse direction when welded and fixed.
Wherein the preset deviation range meets the following conditions:
and (3) taking the closing precision of the bottom tool and the top tool into consideration, and measuring and checking by a total station in the same coordinate system according to a ground sample line:

Specifically, there is a deviation between the top beam 11 and the corresponding bottom beam 12 of the top frame of the net cage frame, that is, there is a deviation in the longitudinal direction, the transverse direction and the vertical direction, so that the top support beam 21 is fixedly connected to the top beam 11, and the bottom support beam 22 is fixedly connected to the bottom beam 12, so as to allow the top support beam 21 and the bottom support beam 22 to be within the preset deviation range.
The predetermined deviation range further includes an angular twist deformation of the top support beam 21 and the bottom support beam 22 corresponding thereto of less than 50mm in the longitudinal direction and an angular twist deformation of the top support beam 21 and the bottom support beam 22 corresponding thereto of less than 50mm in the lateral direction.
Further, before step S6, the method further includes:
providing a plurality of connecting pipes 23 and sleeves 24, sleeving the sleeves 24 on the connecting pipes 23, dividing two adjacent bottom supporting beams 22 into a group by taking the longitudinal central point of the bottom beam 12 as a starting point, and connecting and fixing the bottom supporting beams 22 in the same group through the connecting pipes 23. In this embodiment, the length of the connecting pipe 23 is a predetermined longitudinal distance between the two bottom support beams 22.
Specifically, the sleeve 24 is firstly sleeved on the connecting pipe 23, then the two ends of the connecting pipe 23 are respectively welded with the two bottom support beams 22, and then the bottom support beams 22 are pre-connected with the bottom beam 12 and controlled within a first deviation range.
Referring to fig. 5 again, after the bottom support beam 22 and the connecting tube 23 are connected and fixed, the positions thereof are as follows in this embodiment: at the longitudinal center point of the bottom beam 12, a bottom support beam 22 is provided, the bottom support beam 22 is labeled 0, and the directions along which the bottom support beam 22 extends toward the two ends are sequentially labeled 1, 2, 3 … …, n, i.e., the bottom support beam 22 on the bottom beam 12 is n, … …, 3, 2, 1, 0, 1, 2, 3 … …, n. The connection tubes 23 are connected between the bottom support beams 22, labeled 0 and 1, 2 and 3, 4 and 5, … …, n-1 and n.
Further included after step S7 is:
the position of the sleeve 24 on the connecting pipe 23 is determined by taking the longitudinal center point between the two top support beams 21 corresponding to the bottom support beams 22 at the two ends of the connecting pipe 23 as a reference, and the sleeve 24 is limited and fixed at the position.
The function of the sleeve 24 is to reduce wear between the rope and the connecting tube 23. The position of the sleeve 24 prevents the sleeve 24 from sliding in the length direction of the connection tube 23, and thus prevents the rope from shifting on the sleeve 24 when moving.
Referring to fig. 7, in the present embodiment, the sleeve 24 is limited by a limiting member 25. The two ends of the limiting piece 25 are abutted to the periphery of the sleeve 24, and the limiting piece 25 is connected with the connecting pipe 23 in a welding manner, so that the sleeve 24 is limited.
Further, the four top beams 11 of the top frame can be simultaneously installed on the top support beams 21, and then the four bottom support beams 22 on the four bottom beams 12 of the top frame installation underframe can be simultaneously installed on the bottom support beams 22 on the four bottom beams 12, so that the time is saved, and the construction period is shortened.
According to the technical scheme, the invention has the advantages and positive effects that:
the installation method of the netting tool comprises the steps of installing the top support beam, then installing the bottom support beam and then controlling the position deviation between the bottom support beam and the top support beam corresponding to the bottom support beam.
