[0019] Step S5: transport the switch-sprayer base to the middle of the moon pool, and connect and fix the web plate to the switch-sprayer base by connecting bolts; then, fix the lifting rope of the lifting equipment to the lifting lug, and use the lifting equipment to lift the switch-sprayer base and the web plate together to the vicinity of the corresponding installation position of the drilling platform;

[0020] Step S6: temporarily fix the lifting part and the drilling platform by using a temporary fixing assembly; fine-tune the spatial position of the rotary sprayer base in the horizontal and vertical directions by respectively screwing the lateral adjustment bolts and the vertical adjustment bolts, so that the web corresponds to the web installation positioning point in step S3, and after checking that it is correct through the web positioning inspection lines on both sides, the web is initially fixed at the installation position corresponding to the web of the drilling platform by spot welding;

[0021] Step S7: Remove the connecting bolts between the web and the base of the switch sprayer, and remove the temporary fixing assembly to separate the hoisting parts from the drilling platform, lower the base of the switch sprayer by the hoisting equipment, so that the web has enough welding space, and then weld the web to the installation position corresponding to the web of the drilling platform;

[0022] Step S8: Use the hoisting equipment to hoist the rotary sprayer base to the vicinity of the installation position corresponding to the rotary sprayer base of the drilling platform again, and fine-tune the spatial position of the rotary sprayer base through the lateral adjustment bolts and the vertical adjustment bolts to ensure that the central axis of the cylinder of the rotary sprayer base is aligned with the drilling center line; at the same time, align the rotary sprayer base with the web, check the installation position of the web again through the web positioning inspection line, and then connect and fix the web and the rotary sprayer base through the connecting bolts;

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0040] See also Figures 1 to 3The embodiment of the present invention provides a kind of rotary sprayer base hoisting tool, which includes a hoisting frame 1, a hoisting eye plate 2, a hoisting device and a hoisting piece 4; the hoisting piece 4 includes a lifting ear 41, a cross base 42, a first column 43 and four second columns 44, the height of the second column 44 is less than the height of the first column 43; the first column 43 is arranged vertically, the lower end of the first column 43 is fixedly connected to the center of the cross base 42, and the upper end of the first column 43 is fixedly connected to the lifting ear 41; the four second columns 44 are arranged vertically, and the four second columns 44 are fixedly connected to the center of the cross base 42. The lower end is fixedly connected to the ends of the four sides of the cross base 42, and the upper ends of the four second columns 44 are provided with hanging holes 45 for installing the temporary fixing assembly 11; a placement space 46 for placing the transfer sprayer base 5 is formed between the first column 43 and the four second columns 44; the four sides of the cross base 42 are threadedly connected with vertical adjustment bolts 47, and the vertical adjustment bolts 47 are against the bottom of the transfer sprayer base 5; the four second columns 44 are threadedly connected with lateral adjustment bolts 48, and the lateral adjustment bolts 48 are against the side of the transfer sprayer base 5. It should be noted that in this embodiment, the first column 43 and the second column 44 are preferably channel steel.

[0041] The hoisting frame 1 is fixedly connected to the top surface 61 of the drilling platform 6, the hoisting eye plate 2 is fixedly connected to the middle position of the crossbeam of the hoisting frame 1, and the hoisting eye plate 2 is located on the same straight line as the drilling center line 7; the lifting rope 3 of the hoisting equipment passes through the hoisting eye plate 2 and is fixedly connected to the lifting ear 41, and the hoisting equipment can hoist the rotary sprayer base 5 from the high altitude position of the moon pool 8 from bottom to top to the corresponding installation position of the drilling platform 6.

[0042] According to the rotary sprinkler base hoisting tool of the present invention, when in use, the rotary sprinkler base 5 is placed in the placement space 46 of the hoisting component 4, and the rotary sprinkler base 5 is connected and fixed to the web 51 by connecting bolts, and the rotary sprinkler base 5 and the web 51 can be hoisted together to the corresponding installation position of the drilling platform 6 by lifting the hoisting component 4 with a hoisting device. Since the hoisting eye plate 2 and the drilling center line 7 are located on the same straight line, during the hoisting process, the central axis of the cylinder of the rotary sprinkler base 5 can be more easily aligned with the drilling center line 7, thereby simplifying the installation process and improving work efficiency; at the same time, in the hoisting component 4, the four sides of the cross base 42 are threadedly connected with vertical adjustment bolts 47, and the vertical adjustment bolts 47 are against the bottom of the rotary sprinkler base 5, and the four second columns 44 are threadedly connected with lateral adjustment bolts 48, and the lateral adjustment bolts 48 are against the rotary sprinkler base 5. The sides of the base 5 are abutted against each other, so when the sprinkler base 5 is hoisted to the vicinity of the corresponding installation position of the drilling platform 6, the sprinkler base 5 can be adjusted vertically and horizontally using the vertical adjustment bolts 47 and the lateral adjustment bolts 48 before installation, thereby converting the center axis of the cylinder of the three-dimensional sprinkler base 5 and the drilling center line 7 into a relatively easy in-plane dimensional positioning problem, thus simplifying the problem of installing high-precision equipment in a narrow space at high altitude such as a moon pool 8.

[0043] Exemplarily, in order to improve the structural strength of the hanging component 4 and improve the stability of the hanging component 4 when being hung, the hanging component 4 of this embodiment also includes four diagonal braces 49, and the four diagonal braces 49 are respectively fixedly connected to the upper end of the first column 43 and the middle of the four sides of the cross base 42; the placement space 46 is formed between the four diagonal braces 49 and the four second columns 44; the hanging component 4 of this embodiment also includes four ribs 410, and the four ribs 410 are respectively fixedly connected between the first column 43 and the four sides of the cross base 42.

[0044] Exemplarily, an annular pad 9 is provided between the bottom of the transfer sprayer base and the vertical adjustment bolt 47. It should be noted that the transfer sprayer base 5 is a precision component, and the plane finish and flatness of its bottom are required. The adjustment force is directly supported by the vertical adjustment bolt 47, which is easy to wear. Therefore, the setting of the annular pad 9 can protect the transfer sprayer base 5 on the one hand, and can more conveniently adjust the accuracy of the transfer sprayer base 5 on the other hand.

[0045] Exemplarily, two weighing eye plates 10 for hoisting and balancing the load of the lifting object are welded on the lifting frame 1, and the two weighing eye plates 10 are symmetrically arranged on both sides of the lifting eye plate 2. Such a design can hoist the corresponding load through the weighing eye plates 10 during hoisting, thereby balancing the lifting object, avoiding the tilting and swinging of the sprinkler base 5 and the lifting member 4 during the hoisting process, and ensuring the stability and safety during the hoisting process.

[0046] Exemplarily, the temporary fixing assembly 11 includes a fixing eye plate 112 and a fixing rope 111, wherein the fixing eye plate 112 is fixedly connected to the drilling platform 6, one end of the fixing rope 111 is fixedly connected to the fixing eye plate 112, and the other end of the fixing rope 111 is fixedly connected to the hoisting hole 45. Thus, the provision of the temporary fixing assembly 11 can prevent the hoisting member 4 and the transfer sprayer base 5 from shaking and falling off during the hoisting process, further improve the stability and safety during the hoisting process, and has the advantage of easy installation.

[0047] Also, see Figures 1 to 7 The embodiment of the present invention further provides a method for installing a transfer sprayer base, which uses the transfer sprayer base hoisting tooling described in the above contents, and specifically includes the following steps:

[0048] Step S1: Use an I-beam to erect the hoisting frame 1 on the top surface 61 of the drilling platform 6. Before this step, the construction environment in the cabin needs to be checked to ensure that it meets the installation requirements and avoids affecting other operations.

[0049] Step S2: Use a total station to measure the top surface 61 of the drilling platform 6, determine the position of the drilling center line 7 and mark it, and then weld the lifting eye plate 2 at the middle position of the crossbeam of the lifting frame 1 according to the mark.

[0050] Step S3: Calculate the distance between the web 51 and the drilling center line 7, and use the total station to mark the web installation theoretical line on the drilling platform 6, and then mark the web installation positioning point on the drilling platform 6 according to the web installation theoretical line, and then mark the web positioning inspection lines 12 on both sides of the web installation positioning point in parallel, and mark them.

[0051] Step S4: Place the transfer sprayer base 5 in the placement space 46 of the hanging component 4, and make the vertical adjustment bolt 47 abut against the bottom of the transfer sprayer base 5; then, tighten the lateral adjustment bolt 48 to make the lateral adjustment bolt 48 abut against the side of the transfer sprayer base 5; then, measure the lateral adjustment bolt 48 to make the tightening length of each lateral adjustment bolt 48 the same, so that the position of the transfer sprayer base 5 is close to the middle position of the hanging component 4, and prepare for the positioning of the transfer sprayer base 5 for the centering adjustment after it is hoisted into place.

[0052] Step S5: transport the switch-spout base 5 to the middle of the moon pool 8, and connect and fix the web 51 to the switch-spout base 5 by connecting bolts; then, fix the sling 3 of the lifting equipment to the lifting ear 41, and use the lifting equipment to lift the switch-spout base 5 and the web 51 together to the vicinity of the corresponding installation position of the drilling platform 6.

[0053] Step S6: Use the temporary fixing assembly 11 to temporarily fix the lifting component 4 to the drilling platform 6; by respectively turning the lateral adjustment bolts 48 and the vertical adjustment bolts 47, the spatial position of the rotary sprayer base 5 is fine-tuned in the horizontal and vertical directions, so that the web 51 corresponds to the web installation positioning point in the step S3, and after checking that it is correct through the web positioning inspection lines 12 on both sides, the web 51 is spot welded and initially fixed to the installation position corresponding to the web 51 of the drilling platform 6.

[0054] Step S7: Remove the connecting bolts between the web 51 and the switch base 5, and remove the temporary fixing assembly 11, separate the hoisting member 4 from the drilling platform 6, lower the switch base 5 by the hoisting equipment, so that the web 51 has enough welding space, and then weld the web 51 to the installation position corresponding to the web 51 of the drilling platform 6. It should be noted that the symmetrical welding method is adopted in this step, which can reduce welding deformation.

[0055] Step S8: Use the lifting equipment to lift the rotary sprinkler base 5 to the vicinity of the corresponding installation position of the rotary sprinkler base 5 on the drilling platform 6 again, and fine-tune the spatial position of the rotary sprinkler base 5 by the lateral adjustment bolts 48 and the vertical adjustment bolts 47 to ensure that the central axis of the cylinder of the rotary sprinkler base 5 is aligned with the drilling center line 7; at the same time, align the rotary sprinkler base 5 with the web 51, check the installation position of the web 51 again through the web positioning inspection line 12 to ensure that it is correct, and then connect and fix the web 51 to the rotary sprinkler base 5 by connecting bolts.

[0056] Step S9: loosen the lateral adjustment bolt 48 and the vertical adjustment bolt 47 respectively, lower the hoisting member 4 through the hoisting equipment, withdraw the hoisting member 4, and complete the operation.

[0057] It should be noted that, since the method for installing the rotary sprayer base in this embodiment applies the rotary sprayer base hoisting tooling described in the above contents, it has the same beneficial effects as the rotary sprayer base hoisting tooling, and will not be repeated here.

[0058] Exemplarily, in step S2, after the hoisting frame 1 is built, two weighing eye plates 10 are welded on the hoisting frame 1, and the two weighing eye plates 10 are symmetrically arranged on both sides of the hoisting eye plate 2. Such an operation can hoist the corresponding load through the weighing eye plates 10 during hoisting, thereby balancing the lifting object, avoiding the tilting and swinging of the sprinkler base 5 and the hoisting member 4 during the hoisting process, and ensuring the stability and safety during the hoisting process.

[0059] Exemplarily, in step S4, before placing the cylinder of the transfer sprayer base 5 in the placement space 46 of the hanging member 4, an annular pad 9 is placed on the placement space 46, and the vertical adjustment bolt 47 is abutted against the annular pad 9. Such an operation can protect the transfer sprayer base 5 on the one hand, and can more conveniently adjust the accuracy of the transfer sprayer base 5 on the other hand.

It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
