Description

Technical Field

[0001] This invention belongs to the field of piling machinery technology, specifically relating to an integrated rotary drilling rig rotary platform capable of installing various winches. Background Technology

[0002] Currently, the rotary drilling rig's slewing platform is a key component that fixes the main winch, slewing bearing, and luffing mechanism, ensuring lifting, rotation, and luffing movements during drilling operations. The main winch is fixed to the slewing platform via a winch bracket. Because the winch bracket is a welded structure, it needs to be replaced when the installation dimensions of the main winch reducer and shaft bearings change, resulting in poor versatility of the winch mechanism. Furthermore, the rotary drilling rig's winch drum is large, and the winch bracket structure is complex, weighing anywhere from several hundred kilograms to several tons, leading to extremely high manufacturing costs and negatively impacting the overall weight and cost of the machine. Summary of the Invention

[0003] This invention provides an integrated rotary drilling rig slewing platform capable of supporting various winch installations. The main body of the slewing platform adopts an integrated large vertical plate structure. The large vertical plate has main winch mounting holes and welded reducer mounting seats and shaft end support mounting seats. The two ends of the main winch are fixed to the large vertical plate of the slewing platform body through reducer transition flanges and shaft end support transition flanges. By changing the size of the transition flanges, various sizes of main winches can be installed, enhancing the versatility between the slewing platform and the main winch. The structure is simple and reliable. At the same time, the main winch is directly mounted on the large vertical plate of the slewing platform, which is much lighter than when using a winch bracket, reducing manufacturing costs and overall machine weight.

[0004] The technical solution adopted by this invention to solve its technical problem is: an integrated rotary drilling rig slewing platform capable of installing various winches, including a slewing platform body, several main winches of different sizes, several shaft end support transition flanges, and several reducer transition flanges, wherein:

[0005] The bottom of the main body of the rotary platform is a mounting plate, on which two large vertical plates are arranged opposite each other. Each of the two vertical plates has a main roll mounting hole, and the two main roll mounting holes are coaxial.

[0006] A shaft end support mounting seat is installed at the main roll mounting hole on one large vertical plate, and a reducer mounting seat is installed at the main roll mounting hole on another large vertical plate. The shaft end support mounting seat and the reducer mounting seat are evenly provided with several first mounting holes along the circumferential direction.

[0007] Each main winch is equipped with a main winch shaft end support on one side, and a main winch reducer is installed on the other side of each main winch. Several second mounting holes are evenly opened on both sides of each main winch along the circumferential direction.

[0008] After the largest size main winch is installed on the two large vertical plates, each second mounting hole on the largest size main winch is aligned with a first mounting hole;

[0009] When installing other main winches besides the largest size main winch, one end of the other main winch is connected to the large vertical plate with the shaft end support mounting seat through the shaft end support transition flange, and the other end is connected to the large vertical plate with the reducer mounting seat through the reducer transition flange.

[0010] The shaft end support transition flange is annular in shape. Several first outer mounting holes are evenly opened along the circumference of the shaft end support transition flange. When the shaft end support transition flange is installed on the outside of the shaft end support mounting seat, each first outer mounting hole corresponds to a first mounting hole on the shaft end support mounting seat. Several first inner mounting holes are evenly opened along the circumference of the inner side of the several first outer mounting holes. The opening position of the first inner mounting hole on each shaft end support transition flange is the same as the opening position of the second mounting hole on the side of the main winch on which the main winch shaft end support is installed.

[0011] The reducer transition flange is annular in shape. Several second outer mounting holes are evenly opened along the circumference of the reducer transition flange. When the reducer transition flange is installed on the outside of the reducer mounting base, each second outer mounting hole corresponds to a first mounting hole on the reducer mounting base. Several second inner mounting holes are evenly opened along the circumference of the inner side of the several second outer mounting holes. The opening position of the second inner mounting hole on each reducer transition flange is the same as the opening position of the second mounting hole on the side of the main winch on which the main winch reducer is installed.

[0012] By replacing the shaft end support transition flange with the corresponding one that has the same position as the second mounting hole on the side of the main winch where the main winch shaft end support is installed, and replacing the gearbox transition flange with the corresponding one that has the same position as the second mounting hole on the side of the main winch where the main winch gearbox is installed, the installation of various sizes of main winches can be achieved.

[0013] As a further preferred embodiment of the present invention, one end of the slewing platform body is a head, and the other end is a tail. The slewing platform body also includes a slewing bearing mounting base, several luffing mechanism mounting holes, a bracket mounting base, and a counterweight mounting base, wherein:

[0014] The slewing bearing mounting base is located at the bottom outer side of the two main vertical plates;

[0015] Each large vertical plate has a slope that gradually descends from the side opposite to the mounting plate towards the tail of the slewing platform body from the main roll mounting hole; each large vertical plate has a wave shape that gradually descends from the side opposite to the mounting plate towards the head of the slewing platform body from the main roll mounting hole, and a luffing mechanism mounting hole is set near each wave crest on the wave-shaped side of each large vertical plate.

[0016] Install bracket mounting base and counterweight mounting base at the rear of the main body of the slewing platform.

[0017] As a further preferred embodiment of the invention, it also includes a slewing bearing for rotating the main body of the rotary drilling rig, the slewing bearing being mounted at the bottom of the slewing bearing mounting base.

[0018] As a further preferred embodiment of the present invention, the main winch includes a drum, a wire rope, a rope connector, a main winch reducer, a spring bracket, and a rope clamp, wherein:

[0019] The drum is placed horizontally between the two first mounting holes. A main shaft end support is installed on one side of the drum, and a main winding reducer is installed on the other side.

[0020] The wire rope is wound around the outer wall of the drum, and the exit end of the wire rope is connected to a rope connector.

[0021] The spring bracket is placed horizontally between the two large vertical plates and is arranged on the side of the drum facing the head of the rotary platform body;

[0022] The rope presser is mounted on the spring bracket and presses the wire rope on the drum.

[0023] As a further preferred embodiment of the present invention, the wire rope is wound around the outer wall of the drum in a single-row rope arrangement.

[0024] As a further preferred embodiment of the present invention, the shaft end support transition flange further includes a plurality of first disassembly holes, which are disposed between two first outer mounting holes.

[0025] As a further preferred embodiment of the present invention, the speed reducer transition flange further includes a plurality of second disassembly holes, which are disposed between two second outer mounting holes.

[0026] As a further preferred embodiment of the present invention, a left frame is provided on one side of the rotary platform body and a right frame is provided on the other side; a footboard is installed on the side of the left and right frames away from the rotary platform body; a mounting bracket is provided on the left or right frame near the tail of the rotary platform body; the left frame, right frame, footboard, and mounting bracket are used to install other functional modules of the rotary drilling rig.

[0027] As a further preferred embodiment of the invention, a mast bracket is also included, which is mounted on a bracket mounting base and is used to place the mast during transportation.

[0028] By employing the above technical solutions, the present invention has the following beneficial effects compared to the prior art:

[0029] The main body of the rotary platform of the present invention adopts an integrated large vertical plate structure, and the main winch is directly installed on the large vertical plate. Compared with the installation method of using winch bracket, it is equivalent to only retaining the vertical plates on both sides of the winch bracket, which greatly reduces the structural weight, reduces the overall manufacturing cost and weight of the machine, and at the same time, the structure is simple and reliable, and the working stability is stronger.

[0030] This invention discloses a modular design, which can be matched with various main winch installation sizes by adding or removing the reducer transition flange and shaft end support transition flange. The transition flange is low in cost and easy to standardize, which enhances the versatility between the rotary drilling rig platform and the main winch. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0048] This embodiment provides a preferred implementation scheme, an integrated rotary drilling rig rotary platform capable of accommodating various winch installations, such as... Figures 1 to 7 As shown, this rotary platform includes a rotary platform body 1, several main winches 2 of different sizes, several shaft end support transition flanges 9, and several reducer transition flanges 3, wherein:

[0049] The bottom of the main body 1 of the aforementioned rotary platform is a mounting plate (not shown in the figure). Two large, oppositely arranged vertical plates 16 are mounted on the mounting plate. Each of the two vertical plates 16 has a main roll mounting hole 11, and the two main roll mounting holes 11 are coaxial. A shaft end support mounting seat 12 is installed at the main roll mounting hole 11 on one of the large vertical plates 16, and a reducer mounting seat 13 is installed at the main roll mounting hole 11 on the other large vertical plate 16. The shaft end support mounting seat 12 and the reducer mounting seat 13 have several first mounting holes evenly spaced along the circumference.

[0050] The slewing platform body 1 has a head at one end and a tail at the other. The slewing platform body 1 also includes a slewing bearing mounting base 17, several luffing mechanism mounting holes 18, a bracket mounting base 14, and a counterweight mounting base 15. The slewing bearing mounting base 17 is located at the bottom outer side of two large vertical plates 16. Each large vertical plate 16 slopes downwards from the main coil mounting hole 11 towards the tail of the slewing platform body 1 on the side opposite to the mounting plate. Each large vertical plate 16 also slopes downwards from the main coil mounting hole 11 towards the head of the slewing platform body 1 on the side opposite to the mounting plate, forming a wave shape. Luffing mechanism mounting holes 18 are located near each wave crest on the wave-shaped side of each large vertical plate 16. The bracket mounting base 14 and the counterweight mounting base 15 are installed at the tail of the slewing platform body 1. A drill mast bracket 4 is mounted on the bracket mounting base 14 for placing the drill mast during transportation.

[0051] This embodiment also includes a slewing bearing 7 for the rotation of the rotary drilling rig host, which is mounted at the bottom of the slewing bearing mounting base 17.

[0052] Each main winch 2 has a main winch shaft end support 27 installed on one side, and a main winch reducer 24 installed on the other side. Several second mounting holes are evenly spaced along the circumference on both sides of each main winch 2. When the largest main winch 2 is installed on the two large vertical plates 16, each second mounting hole on the largest main winch 2 is aligned with a first mounting hole. When installing other main winches 2 besides the largest main winch 2, one end of each other main winch 2 is connected to the large vertical plate 16 with the shaft end support mounting seat 12 via the shaft end support transition flange 9, and the other end is connected to the large vertical plate 16 with the reducer mounting seat 13 via the reducer transition flange 3.

[0053] The aforementioned shaft end support transition flange 9 is annular in shape. A plurality of first outer mounting holes 91 are evenly distributed along the circumference of the shaft end support transition flange 9. When the shaft end support transition flange 9 is installed outside the shaft end support mounting base 12, each first outer mounting hole 91 corresponds to a first mounting hole on the shaft end support mounting base 12. A plurality of first inner mounting holes 92 are evenly distributed along the circumference of the inner side of the plurality of first outer mounting holes 91. The position of the first inner mounting hole 92 on each shaft end support transition flange 9 is the same as the position of the second mounting hole on the side of the main winch 2 where the main winch shaft end support 27 is installed. Specifically, the shaft end support transition flange 9 also includes a plurality of first disassembly holes 93, which are located between two first outer mounting holes 91. The first disassembly holes 93 facilitate the disassembly and assembly of the shaft end support transition flange 9.

[0054] The aforementioned reducer transition flange 3 is annular in shape. A plurality of second outer mounting holes 31 are evenly distributed along the circumference of the reducer transition flange 3. When the reducer transition flange 3 is installed on the outside of the reducer mounting base 13, each second outer mounting hole 31 corresponds to a first mounting hole on the reducer mounting base 13. A plurality of second inner mounting holes 32 are evenly distributed along the circumference of the inner side of the plurality of second outer mounting holes 31. The position of each second inner mounting hole 32 on the reducer transition flange 3 is the same as the position of the second mounting hole on the side of the main winch 2 where the main winch reducer 24 is mounted. Specifically, the reducer transition flange 3 also includes a plurality of second disassembly holes 33, which are located between two second outer mounting holes 31. The second disassembly holes 33 facilitate the disassembly and assembly of the reducer transition flange 3.

[0055] This implementation scheme achieves the installation of main winches 2 of various sizes by replacing the shaft end support transition flange 9 on the side of the main winch 2 where the second mounting hole is located, which is the same as the required size of the main winch 2, and replacing the reducer transition flange 3 on the side of the main winch 2 where the second mounting hole is located, which is the same as the required size of the main winch 2, which is the same as the required size of the main winch 2, to install the main winch 2 of various sizes.

[0056] The aforementioned main winch includes a drum 21, a wire rope 23, a rope connector 22, a main winch reducer 24, a spring bracket 25, and a rope presser 26. The drum 21 is horizontally positioned between two first mounting holes. A main winch shaft end support 27 is mounted on one side of the drum 21, and the main winch reducer 24 is mounted on the other side. The wire rope 23 is wound around the outer wall of the drum 21, and the exit end of the wire rope 23 is connected to the rope connector 22. Preferably, the wire rope 23 is wound around the outer wall of the drum 21 in a single-row arrangement. The spring bracket 25 is horizontally positioned between two large vertical plates 16 and arranged on the side of the drum 21 facing the head of the rotary platform body 1. The rope presser 26 is mounted on the spring bracket 25 and presses the wire rope 23 on the drum 21.

[0057] In this implementation scheme, a left frame 6 is set on one side of the rotary platform body 1, and a right frame 8 is set on the other side; a foot pedal 10 is installed on the side of the left frame 6 and the right frame 8 that is away from the rotary platform body 1; a mounting bracket 5 is set on the left frame 6 or the right frame 8 near the tail of the rotary platform body 1; the left frame 6, the right frame 8, the foot pedal 10, and the mounting bracket 5 are used to install other functional modules of the rotary drilling rig.

[0058] This implementation scheme omits the winch support structure and directly designs the rotary platform to have both rotation and support functions for the main winch 2, thus reducing manufacturing costs. Simultaneously, by setting several shaft end support transition flanges 9 and several reducer transition flanges 3 of different sizes to cooperate with the corresponding sizes of the main winch 2, the unified rotary platform can accommodate the installation of various sizes of main winches 2.

[0059] When assembling a rotary drilling rig, such as Figure 1-2 As shown, if the reducer transition flange 3 and shaft end support transition flange 9 are required, select appropriate reducer transition flange 3 and shaft end support transition flange 9 according to the installation dimensions. First, connect the fixed ends of the main winding reducer 24 and the main winding shaft end support 27 to the reducer transition flange 3 and the shaft end support transition flange 9 respectively. Then, connect the parts of the main winding reducer 24 and the main winding shaft end support 27 that rotate with the drum 21 to both sides of the drum 12. Subsequently, hoist the drum 21 to the inside of the large vertical plate 16 of the rotary platform body 1, and assemble the fixed ends of the main winding reducer 24 and the main winding shaft end support 27 with the rotating parts. Finally, connect the reducer transition flange 3 and the shaft end support transition flange 9 to the reducer mounting seat 13 and the shaft end support mounting seat 12 on the large vertical plate 16 of the rotary platform body 1 respectively. After completing the above assembly, assemble the other functional modules of the rotary drilling rig in an orderly manner. The above is only one assembly process; other assembly processes can also be used.

[0060] When assembling a rotary drilling rig, such as Figure 7 As shown, if the reducer transition flange 3 and shaft end support transition flange 9 are not required, i.e., when the maximum size main winch 2 is used, first connect the main winch reducer 24 and the main winch shaft end support 27, which are parts that rotate with the drum 21, to both sides of the drum 12. Then, hoist the drum 21 to the inside of the large vertical plate 16 of the rotary platform body 1, assemble the fixed end of the main winch reducer 24 and the main winch shaft end support 27 with the rotating part, and then directly connect the fixed end of the main winch reducer 24 and the main winch shaft end support 27 to the reducer mounting seat 13 and the shaft end support mounting seat 12 on the large vertical plate 16 of the rotary platform body 1.
