Description

Technical Field

[0001] The present invention relates to the technical field of drilling rig ship equipment, and in particular to a drilling operation device and method for a drilling rig on a drilling rig ship. Background Art

[0002] my country's rapid economic development has brought tremendous development opportunities to the transportation and logistics industry. Compared to rail and road transport, waterway transportation offers advantages such as low investment, greater capacity, lower costs, lower energy consumption, and lower freight rates, and has long been strongly supported by the government. This rapid economic growth has led to a surge in cargo volume, resulting in a demand for larger vessels, which in turn has fueled the growth of the shipping industry and ports. As ships become larger, waterways need to be widened and deepened to accommodate these larger vessels. This work is accomplished by reef blasting vessels and dredgers. Reef blasting vessels drill holes in hard reefs, fill the holes with explosives, and detonate them to shatter the reef. Dredgers remove the rubble and clear the waterway. Due to differences in geotechnical conditions, drilling requires varying technical levels and drilling depths, necessitating frequent replacement of casing and drill pipe.

[0003] Replacing casing and drill pipe is the most tedious and arduous task for drilling rig operators. Currently, it is done with the help of some manual tools such as wrenches, pipe clamps, crowbars, etc. In serious cases, the casing is stuck very tightly and even needs to be heated by fire. This method of replacing casing is not only labor-intensive and inefficient, but also has serious safety hazards. Injuries often occur. If the clamp is not firm, the casing will fall into the water and be lost. Summary of the Invention

[0028] 3. Beneficial effects

[0029] 1. The main tongs and backup tongs work together to lock and rotate the upper and lower sections of the casing, which mechanizes the casing replacement and saves manpower. At the same time, it avoids the risk of the casing falling into the water and greatly improves safety. The front guide rod and the rear guide rod work together to provide support and guidance to prevent the upper and lower casings from lateral movement, and can also adjust the distance between the main tongs and the backup tongs, making it easier to separate and connect the upper and lower casings.

[0030] 2. By setting the first connecting piece, it is convenient to connect the transparent acrylic plate, which not only blocks the through groove on the upper shell to prevent foreign objects from entering and damaging the gears, but also does not affect the observation of the internal structure. Since there are a large number of gears inside the upper shell, when filling the gears with lubricating oil, either the upper shell or the transparent acrylic plate needs to be disassembled, which is very troublesome. Therefore, by setting the second connecting piece, a connecting cover and an oil storage box can be installed on it, which is convenient for directly filling the gears inside the upper shell with lubricating oil, saving the time of disassembly.

[0031] 3. With the help of the threaded ring, quantitative lubricating oil can be added. Subsequently, by using the threaded ring and the oil delivery mechanism in combination, since the threaded ring limits the forward movement of the first screw, the oil delivery mechanism can effectively prevent the first screw and the push rod from moving backward, thereby limiting the first screw to prevent it from moving at will and interfering with the use of the entire device.

[0032] 4. Insert the connecting tube on the mounting base into the first connecting groove on the second connecting piece, and then use the insertion rod in the connecting tube to plug into the second connecting groove on the second connecting piece, so as to directly install the connecting cover on the second connecting piece. Since the rotating rods at the four corners of the connecting box are connected by connecting belts and pulleys, synchronous rotation can be achieved, which is convenient for installation.

The hydraulic motor 75 is arranged at the top of the upper shell 8.

[0055] Gear set 10, the output shaft of the hydraulic motor 75 is connected to the main tongs 71 through the gear set 10;

[0056] The chuck assembly also includes a chuck base 1, a slide 2, a caliper 3, a caliper arm 4, a cylinder 5 and a cylinder piston rod joint 6. The hydraulic power tongs component 7 is fixedly mounted on the top of the chuck base 1, the slide 2 is vertically fixedly mounted on the side of the chuck base 1, the caliper 3 and the caliper arm 4 are both horizontally movably mounted in the chuck base 1, the cylinder 5 is horizontally arranged, and one end is hinged to the chuck base 1, and the other end is connected to the caliper arm 4 through the cylinder piston rod joint 6. The sleeve is composed of the above components combined together to achieve clamping or loosening. This work is achieved by the reversing valve and hydraulic motor on the ship.

[0057] The gear set 10 includes a main gear 101, a driven gear 102, and a reduction gear 103. The main gear 101 is connected to the output shaft of the hydraulic motor 75. The driven gear 102 is fixedly sleeved on the main tongs 71. The reduction gear 103 is rotatably mounted in the upper housing 8 via a rotating shaft 104. The rotating shaft 104 is vertically arranged. A power cylinder is provided in the lower housing 9. The backup tongs 72 are provided with dual gears. A rack is provided in the lower housing 9. The rack is connected to the power cylinder and meshes with the dual gears.

[0058] Slide 2 is composed of slide base plate, slide web, slide panel and nylon lining plate. The slide base plate and the chuck base 1 base plate are drilled and tightly connected by bolts. The nylon lining plate has grooves to match the slide rails on the drill frame.

[0059] The chuck seat 1 is composed of a lifting ear plate, a semicircular protective wall, an extension ear plate, a limit ring, and a chuck base plate. The chuck base plate and the slide base plate are drilled and tightly connected by bolts.

[0060] A drilling operation method of a drilling rig comprises the following steps:

[0061] S1: Fix the casing so that the upper and lower sections of the casing are located in the main clamp 71 and the backup clamp 72 respectively, and the main clamp 71 and the backup clamp 72 clamp the casing;

[0062] S2: Rotation and disassembly: the hydraulic motor 75 drives the main tongs 71 to rotate, and the power cylinder 5 drives the backup tongs 72 to clamp or release the casing;

[0063] S3: lifting and lowering, separation or combination, the front guide rod 73 and the rear guide rod 74 are extended or shortened, and the upper and lower sleeves are separated or connected;

[0064] S4: Add lubricating oil, rotate the threaded ring 18, and use the threaded ring 18 to limit the position. Then directly press the push plate 17, so that the push plate 17 drives the piston plate 39 to spray the lubricating oil through the first delivery pipe 38, the hollow ball 37, and the second delivery pipe 40. The sprayed lubricating oil will be sprayed onto the teeth on the upper and lower sides of the reduction gear 103. As the reduction gear 103 rotates in coordination with other gears, the lubricating oil can be transferred to them.

[0065] S5: By rotating the second screw 21 on the connecting cover 14, the second screw 21 drives the corresponding sealing plug 24 to move out of the vent tube 23, and then pulling the push plate 17 to return the piston plate 39 to its original position, lubricating oil can be added through the vent tube 23. Lubricating oil can also be added by rotating the second screw 21 on the oil storage box 12, so that the second screw 21 drives the sealing plug 24 to move out of the vent tube 23;

[0066] S6: By rotating the rotating plate 26, the rotating plate 26 rotates the multiple forward and reverse screws 31 together through the connecting belt 27 and the pulley 25, and the forward and reverse screws 31 cause the insertion rod 35 to disengage from the first connecting groove 19 and return to the inside of the connecting tube 29, thereby facilitating its removal;

[0067] When using this equipment, the upper and lower sections of the casing are respectively clamped by the main tongs 71 and the backup tongs 72, and then pressure is injected into the hydraulic motor 75 through the hydraulic pump station on the hull. The hydraulic motor 75 runs, driving the main gear 101 on its output shaft to rotate, the main gear 101 drives the reduction gear 103 to rotate, the reduction gear 103 drives the driven gear 102 to rotate, and the driven gear 102 drives the main tongs 71 to rotate. The operation of the backup tongs 72 is driven by the power cylinder, the power cylinder drives the rack to move, and the rack drives the double gears to rotate, thereby realizing the closing and separation of the backup tongs 72. According to the operation requirements of separation and combination, the main tongs 71 can be rotated forward or reversed to realize the tightening and loosening of the upper and lower sleeves, so as to achieve the mechanized operation of replacing casings in reef blasting ship operations, save manpower, and effectively avoid the risk of casing falling into the water.

[0068] When the casing is separated or combined, the front guide rod 73 and the rear guide rod 74 have a supporting and guiding function to prevent the upper and lower casings from moving laterally, and can also adjust the distance between the main clamp 71 and the backup clamp 72 to facilitate the separation and combination of the upper and lower casings.

[0069] Example 2

[0070] like Figure 8 、 Figure 10-12As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: a first connecting member 11 and a second connecting member 13 are respectively fixed on the front and rear sides of the upper shell 8, a transparent acrylic plate is installed on the first connecting member 11, and a plurality of first connecting grooves 19 and second connecting grooves 20 are provided on the second connecting member 13. A connecting mechanism is provided on the second connecting member 13, and the connecting mechanism includes a connecting cover 14. The four corners of the connecting cover 14 are fixed with mounting seats 28, and a connecting pipe 29 is fixedly provided on the mounting seat 28. The connecting pipe 29 is plugged into the first connecting groove 19, and two first through holes 30 are penetrated on both sides of the connecting pipe 29. The diameter of the first through hole 30 is the same as that of the second connecting groove 20. A forward and reverse screw 31 is provided inside the connecting pipe 29, and ball bearings are sleeved on both ends of the forward and reverse screw 31. The ball bearing is fixedly connected to the connecting tube 29, and the positive and negative threads on the forward and reverse screw rods 31 are both threadedly connected with a threaded plate 32, and the threaded plate 32 is slidably connected to the connecting tube 29. The two threaded plates 32 are fixedly provided with an insertion rod 35 on the opposite sides of the two threaded plates 32, and the insertion rod 35 is plugged into the first through hole 30 and the first connecting groove 19. A second bevel gear 34 is fixedly provided on the forward and reverse screw rods 31, and a rotating rod 36 is provided through the connecting tube 29. The rotating rod 36 is rotatably connected to the connecting tube 29, and the first bevel gear 33 is fixed on one end of the rotating rod 36 located inside the connecting tube 29. The first bevel gear 33 meshes with the second bevel gear 34, and a pulley 25 is fixed on one end of the rotating rod 36 located outside the connecting tube 29. The pulleys 25 located at the four corners of the connecting cover 14 are connected by a connecting belt 27, and a rotating plate 26 is fixed on one end of the rotating rod 36 away from the first bevel gear 33;

[0071] By inserting the four connecting tubes 29 on the mounting seat 28 into the second through holes on the second connecting member 13, and then rotating one of the rotating plates 26 at will, the rotating plate 26 will drive the rotating rod 36 to rotate, and the rotating rod 36 will drive the remaining rotating rods 36 to rotate through the connecting belt 27 and the pulley 25, so that multiple rotating rods 36 will rotate synchronously, and the rotation of the rotating rod 36 will drive the forward and reverse screws 31 to rotate through the first bevel gear 33 and the second bevel gear 34, and the forward and reverse screws 31 will drive the two threaded plates 32 to move in directions away from each other, so that the insertion rod 35 on the threaded plate 32 passes through the first through hole 30 and is plugged into the second connecting groove 20 on the second connecting member 13, effectively fixing it on the second connecting member 13, and facilitating installation and disassembly.

[0072] Example 3

[0073] like Figure 8 、 Figure 9 、 Figure 13-16As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that: an oil storage box 12 is fixedly provided on the connecting cover 14, a sliding sleeve 15 is fixedly provided on the front of the oil storage box 12, a first screw 16 is slidably connected inside the sliding sleeve 15, a piston plate 39 is fixedly provided at one end of the first screw 16 located inside the oil storage box 12, the four upper, lower, left and right sides of the piston plate 39 are in contact with the oil storage box 12, a rubber piston is fixedly provided on the surface of the piston plate 39 in contact with the oil storage box 12, the piston plate 39 is slidably connected to the oil storage box 12, a push plate 17 is fixedly provided at one end of the first screw 16 located outside the oil storage box 12, a threaded ring 18 is threadedly connected to the first screw 16, a first delivery pipe 38 is fixedly provided on the back of the oil storage box 12, a hollow ball 37 is connected to the first delivery pipe 38, and two oil delivery mechanisms are provided on the hollow ball 37. The second delivery pipe 40 is included. A fixing ring 45 is fixedly provided inside the second delivery pipe 40. A placement groove is provided on the fixing ring 45. A blocking plate 44 is inserted into the placement groove. A fixing plate 41 is provided above the blocking plate 44. The fixing plate 41 is connected to the blocking plate 44 through a spring 42 and a telescopic rod 43. The telescopic rod 43 is located inside the spring 42. The second delivery pipe 40, the hollow ball 37, and the first delivery pipe 38 are connected. The oil storage box 12 and the connecting cover 14 are all fixedly provided with a mounting bracket 22 on the top. A second screw 21 is provided through the mounting bracket 22. The second screw 21 is threadedly connected to the mounting bracket 22. A second through hole is provided through the top of the connecting cover 14. The second through hole is located just below the second screw 21. A breathable pipe 23 is fixedly provided at both front and rear ends of the top of the oil storage box 12. A sealing plug 24 is inserted into the inside of the breathable pipe 23. The sealing plug 24 is fixedly connected to the second screw 21.

[0074] By rotating the threaded ring 18, the threaded ring 18 is moved to a designated position on the first screw 16. Due to the position limitation of the threaded ring 18, quantitative addition of lubricating oil can be achieved;

[0075] When the threaded ring 18 is adjusted, the push plate 17 is pushed, and the push plate 17 drives the piston plate 39 through the first screw 16 to squeeze the lubricating oil in the oil storage box 12, so that the lubricating oil is transported to the second delivery pipe 40 through the first delivery pipe 38 and the hollow ball 37. The lubricating oil delivered to the second delivery pipe 40 will squeeze the blocking plate 44, so that the blocking plate 44 squeezes the spring 42 and thus disengages from the placement groove in the fixing ring 45. Due to the detachment of the blocking plate 44, the lubricating oil will be ejected along the gap, and finally, it will be sprayed onto the reduction gear 103 through the first oil delivery pipe. Since two second delivery pipes 40 are provided on the hollow ball 37, the upper and lower ends of the reduction gear 103 can be filled with lubricating oil at the same time.

[0076] Since the reduction gear 103 rotates continuously in conjunction with other gears, the lubricating oil added to the reduction gear 103 can be transferred to the other gears;

[0077] By providing the limit block 46, when the piston plate 39 and the limit block 46 cannot move further, it indicates that lubricating oil needs to be added to the oil storage box 12. Due to the action of the spring 42, the blocking plate 44 will block the fixing ring 45, resulting in a sealed state between the piston plate 39 and the fixing ring 45, so that the first screw 16 will not be able to be pulled in the opposite direction. Due to the action of the threaded ring 18, the movement of the first screw 16 can be effectively limited to prevent it from moving at will and affecting the use.

[0078] By rotating the second screw 21 on the connecting box, the second screw 21 drives the sealing plug 24 to move out of the air tube 23, so that the piston plate 39 and the fixing ring 45 will not be sealed. The first screw 16 can be pulled to return the first screw 16 to its original position. Subsequently, lubricating oil can be added with the help of the air tube 23, and by rotating the second screw 21 on the oil storage box 12, the second screw 21 drives the sealing plug 24 to move out of the air tube 23, and lubricating oil can also be added.

[0079] It should be noted that the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0080] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
