Description

Technical Field

[0001] This application relates to the field of drilling equipment technology, and in particular to a drilling device for a spherical tank tie rod. Background Technology

[0002] Spherical tank tie rods are quite long and heavy, typically 6 to 8 meters long and weighing over 1 ton, making them difficult to move. Machining threads on spherical tank tie rods requires first machining a center hole, which is currently typically done using a boring machine or other large equipment. However, machining the center hole requires repeatedly lifting and lowering the tie rod, posing significant safety hazards. Furthermore, tie rods are crucial load-bearing components of spherical tanks, with a high degree of standardization and large production volumes, while large equipment like boring machines is inefficient and costly.

[0045] Please see Figure 1 and Figure 2 This application provides a drilling device for a spherical tank tie rod, used for machining the center hole of the spherical tank tie rod.

[0046] The drilling equipment includes a drilling device 2 and a position adjustment device 3. The drilling device 2 is used to drill holes in the spherical tank tie rod 1. The position adjustment device 3 is located on one side of the drilling device 2 and is used to adjust the position of the drilling device 2, so that the drilling device 2 can drill holes in the spherical tank tie rod 1 placed in different positions, thereby improving processing efficiency and saving labor costs.

[0047] Specifically, the position adjustment device 3 includes a base 31, a first position adjustment structure 32, a second position adjustment structure 33, and a third position adjustment structure 34. A mounting plate is formed on the base 31, and the third position adjustment structure 34 is disposed on the mounting plate. The second position adjustment structure 33 is located between the first position adjustment structure 32 and the third position adjustment structure 34, and is connected to both. The first position adjustment structure 32 is connected to the drilling device 2 and is used to move the drilling device 2 along the y-axis. The second position adjustment structure 33 is used to move the first position adjustment structure 32 along the x-axis. The third position adjustment structure 34 is used to move the second position adjustment structure 33 along the z-axis.

[0048] When processing the center hole of a spherical tank tie rod using the aforementioned drilling equipment, the spherical tank tie rods to be processed can be arranged on the work stand 100, and the drilling equipment can be placed at a suitable position in front of the work stand 100. When the center hole of one spherical tank tie rod is processed, the drilling device 2 can be moved to the corresponding position of the next spherical tank tie rod using the position adjustment device 3, and then the processing of the next spherical tank tie rod can be carried out, and so on. The first position adjustment structure 32 can move the drilling device 2 along the height direction, the second position adjustment structure 33 can move the drilling device 2 along the left and right direction, and the third position adjustment structure 34 can move the drilling device 2 along the front and back direction. In this way, the drilling device 2 can move in six dimensions, allowing the drilling device 2 to switch between different spherical tank tie rods 1 without moving the spherical tank tie rods 1, thereby improving the processing efficiency of the spherical tank tie rods, reducing the processing difficulty and labor costs, and avoiding the safety hazards caused by moving the spherical tank tie rods.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the first position adjustment structure 32 includes a support frame 321, a pulley 322, a lifting member 323, and a counterweight 324. The support frame 321 extends in a direction close to or away from the drilling device 2. The pulley 322 is mounted on the support frame 321. The lifting member 323 is slidably connected to the pulley 322, and one end of the lifting member 323 is connected to the drilling device 2, while the other end is connected to the counterweight 324, so that the lifting member 323 can drive the drilling device 2 to move along the y-axis.

[0050] When moving the drilling device 2, the counterweight 324 makes it easier to lift the drilling device 2, reducing labor intensity and making it easier to move the drilling device 2.

[0051] Multiple pulleys 322 can be configured, and the multiple pulleys 322 are distributed at intervals along the extension direction of the support frame 321, which can improve the movement stability of the lifting component 323. For example, two sets of pulleys 322 can be provided, and the pulleys 322 can be fixed pulleys 322, with the two sets of pulleys 322 respectively located at both ends of the extension direction of the support frame 321.

[0052] In some embodiments, two lifting members 323 may be provided, arranged in parallel. In this case, pulleys 322 are arranged in pairs and parallel, respectively slidably connected to the two lifting members 323, so that the drilling device 2 can move up and down under the drive of the lifting members 323. The above structure can improve the connection stability between the lifting members 323 and the counterweight 324 and the drilling device 2, as well as the lifting balance of the drilling device 2. It is understood that in other embodiments, more than two lifting members 323 may also be provided to ensure the movement stability of the counterweight 324 and the drilling device 2.

[0053] For example, the lifting component 323 can be made of steel wire rope. Steel wire rope has high strength, ensuring that the lifting component 323 can lift the drilling device 2 with a certain weight, and has a long service life.

[0054] Understandably, the installation height of the support frame 321 is higher than the height of the drilling device 2, so as to ensure that the first position adjustment structure 32 can lift the drilling device 2 and facilitate the movement of the drilling device 2.

[0055] The second position adjustment structure 33 includes a first slider 331 and a first slide rail 332. The first slide rail 332 extends along the x-axis, and the first slider 331 is connected to the support frame 321 and slidably connected to the first slide rail 332. When the first slider 331 slides along the first slide rail 332, it can drive the support frame 321 to move back and forth to move closer to or further away from the drilling device 2.

[0056] The third position adjustment structure 34 includes a second slider 341 and a second slide rail 342. The second slide rail 342 is mounted on the base 31 and extends along the z-axis. The second slider 341 is connected to the first slide rail 332 and slidably connected to the second slide rail 342. When the second slider 341 slides along the second slide rail 342, it can drive the second position adjustment structure 33 to move left and right, thereby driving the drilling device 2 to move left and right.

[0057] In some embodiments, the third position adjustment structure 34 is disposed on the base 31, the second position adjustment structure 33 is disposed above the third position adjustment structure 34, and the first position adjustment structure 32 is disposed above the second position adjustment structure 33, that is, the first position adjustment structure 32, the second position adjustment structure 33 and the third position adjustment structure 34 are stacked.

[0058] This layered arrangement makes the entire position adjustment device 3 more compact in structure, effectively saving space. At the same time, this design also makes the equipment more flexible in its adjustment; the drilling device 2 can be moved in three-dimensional space through the coordinated action of the three position adjustment structures to accommodate switching between different spherical tank rods. Furthermore, the layered arrangement helps improve the stability and load-bearing capacity of the equipment, ensuring stable operation during the drilling process.

[0059] In some embodiments, the drilling apparatus 2 includes a frame 21, a drilling assembly 22, a fixing assembly 23, and a feed assembly 24. The frame 21 is configured as a support structure for the drilling apparatus 2.

[0060] The frame 21 may include a frame-type mounting section, on which the punching assembly 22 and the feeding assembly 24 are disposed. The frame 21 may also include a support section, which is disposed opposite to the punching assembly 22 and extends in a direction close to or away from the punching assembly 22. A fixing assembly 23 is disposed on the support section to fix the support tank tie rod 1.

[0061] The drilling assembly 22 is used to drill holes in the spherical tank tie rod 1. The drilling assembly 22 includes a motor. The motor can be a servo motor, which offers high precision and allows for accurate control of the drilling depth in the spherical tank tie rod. Furthermore, the servo motor, as a power source, enables adjustable and visually controlled rotation speed, allowing for speed adjustments based on specific processing requirements.

[0062] The punching assembly 22 also includes a drilling component, which is connected to the output shaft of the motor and is driven by the output shaft of the motor.

[0063] like Figures 3 to 5 As shown, the fixing component 23 is located in the moving direction of the drilling component 22 and is used to fix the spherical tank tie rod 1 to ensure the stability of the spherical tank tie rod 1 during drilling and to ensure the drilling accuracy of the spherical tank tie rod.

[0064] In some embodiments, such as Figure 3 As shown, the fixing component 23 includes a first positioning block 231 and a positioning structure 232. The first positioning block 231 and the positioning structure 232 fix the outer periphery of the spherical tank rod 1, thereby achieving rapid positioning of the spherical tank rod 1.

[0065] A first positioning block 231 is disposed on the frame 21. The first positioning block 231 is disposed on the support portion. At least one first positioning block 231 is provided, and at least one first positioning block 231 is sequentially distributed along the length direction of the spherical tank tie rod 1 to ensure that the spherical tank tie rod 1 can be stably fixed. For example, two first positioning blocks 231 are provided, and the two first positioning blocks 231 are respectively disposed at both ends of the support portion along its length direction, so that the spherical tank tie rod 1 is fixed at both the near end and the far end from the drilling assembly, improving the stability of the spherical tank tie rod 1 during drilling.

[0066] The first positioning block 231 has a first positioning groove 2311. The two walls of the first positioning groove 2311 are inclined relative to each other, and the width of the first positioning groove 2311 gradually decreases along the direction from the groove opening to the bottom of the groove. The two walls of the first positioning groove 2311 cooperate with the positioning structure 232 to clamp the spherical tank pull rod 1. The width of the first positioning groove 2311 forms a gradually changing structure, which is not affected by the outer circumferential dimensions and errors of the spherical tank pull rod 1, thus improving the applicability of the fixing component 23.

[0067] In other embodiments, the first positioning groove 2311 may also be configured as an arc-shaped groove that is adapted to the outer peripheral surface of the ball tank pull rod 1.

[0068] like Figure 3 As shown, the positioning structure 232 includes a mounting bracket 2321 and a fixing member 2322. The mounting bracket 2321 is mounted on the frame 21, and a receiving space 23211 is formed between the mounting bracket 2321 and the frame 21. The fixing member 2322 passes through the mounting bracket 2321 and extends into the receiving space 23211. The fixing member 2322 can move in a direction close to or away from the spherical tank pull rod 1. The spherical tank pull rod 1 is fixed between the first positioning block 231 and the fixing member 2322. The mounting bracket 2321 is mounted above the support portion and has a mounting hole. The mounting hole is positioned directly opposite the top of the support portion and has an internal thread. The fixing member 2322 has a screw portion and a rotating portion. The screw portion passes through the mounting hole and is threadedly connected to the mounting hole. The rotating portion is positioned above the mounting bracket 2321. The rotating portion facilitates the fixing member 2322 to be screwed into or out of the mounting bracket 2321. Rotating the rotating wheel allows the screw to be screwed downwards into the receiving space 23211, so that the bottom of the screw abuts against the ball tank lever 1, thereby fixing the ball tank lever 1 between the first positioning block 231 and the fixing member 2322; or, rotating the rotating wheel in the opposite direction allows the screw to be screwed upwards out of the mounting bracket 2321, thereby releasing the clamping of the ball tank lever 1.

[0069] In other embodiments, such as Figure 4 As shown, the positioning structure 232 also includes a second positioning block 2323. The second positioning block 2323 is disposed in the accommodating space 23211 and connected to the fixing member 2322. The second positioning block 2323 has a second positioning groove 23231, which is arranged opposite to the opening of the first positioning groove 2311. The spherical can pull rod 1 is fixed between the first positioning groove 2311 and the second positioning groove 23231. By clamping the spherical can pull rod 1 with the first positioning groove 2311 and the second positioning groove 23231, the contact area between the first positioning block 231 and the positioning structure 232 and the spherical can pull rod 1 can be increased, thereby improving the clamping stability of the spherical can pull rod 1.

[0070] The two walls of the second positioning groove 23231 are inclined relative to each other, and the width of the second positioning groove 23231 gradually decreases along the direction from the opening to the bottom of the groove. The two walls of the second positioning groove 23231 cooperate with the first positioning groove 2311 to clamp the spherical tank pull rod 1. The width of the second positioning groove 23231 forms a gradually changing structure, which is not affected by the outer circumferential dimensions and errors of the spherical tank pull rod 1, thus improving the applicability of the fixing component 23.

[0071] In other embodiments, the second positioning groove 23231 may also be configured as an arc-shaped groove, which is adapted to the outer peripheral surface of the ball tank pull rod 1.

[0072] like Figure 5 and Figure 6 As shown, the feed assembly 24 is located at the bottom of the mounting section. The feed assembly 24 is connected to the drilling assembly 22 and can move the drilling assembly 22 closer to or away from the spherical tank pull rod 1. The feed assembly 24 can control the feed rate and machining depth of the drilling assembly 22 to ensure machining efficiency and adapt to the machining requirements of center holes of different specifications.

[0073] The feed assembly 24 includes a guide 241, a mounting base 242, and a rotation adjustment mechanism 243. The rotation adjustment mechanism 243 drives the mounting base 242 to slide along the guide 241, thereby controlling the drilling depth of the drilling assembly 22 and achieving different processing requirements.

[0074] Specifically, the guide member 241 is mounted on the frame 21 and extends along the moving direction of the punching assembly 22.

[0075] Mounting base 242 is located below and connected to the drilling assembly 22, and is used to support and fix the drilling assembly 22. Mounting base 242 has a through hole, and guide member 241 passes through the through hole, allowing mounting base 242 to slide along guide member 241 to move closer to or further away from the machined surface of the spherical tank tie rod 1. Guide member 241 can be a cylindrical rod, which, in conjunction with the through hole, facilitates the movement of the drilling assembly 22 by mounting base 242.

[0076] In other embodiments, the guide 241 may also be configured as a guide rail, and the bottom of the mounting base 242 may be configured with a guide groove that fits the guide rail.

[0077] Furthermore, two guide members 241 are provided, and the two guide members 241 are arranged in parallel to improve the movement stability of the mounting base 242, thereby improving the drilling accuracy.

[0078] like Figure 5As shown, the mounting base 242 includes a support portion 2421 and a guide portion 2422. The support portion 2421 supports and fixes the drilling assembly 22, and a through hole is provided in the support portion 2421. The guide portion 2422 is located below the support portion 2421 and extends along the moving direction of the drilling assembly 22. The guide portion 2422 is drively connected to the rotation adjustment mechanism 243. The guide portion 2422 increases the contact area with the rotation adjustment mechanism 243, thereby increasing the friction between the guide portion 2422 and the rotation adjustment mechanism 243, ensuring that the mounting base 242 can move when the rotation adjustment structure is rotated.

[0079] like Figure 1 and Figure 4 As shown, the rotation adjustment mechanism 243 includes a handwheel 2431, a connecting shaft 2432, and a roller 2433. The handwheel 2431 is located on one side of the frame 21. The connecting shaft 2432 passes through the frame 21 and is connected to both the handwheel 2431 and the roller 2433. The handwheel 2431 and the roller 2433 rotate coaxially. The roller 2433 is located below the mounting base 242 and is connected to the mounting base 242 for driving the mounting base 242 closer to or away from the spherical tank pull rod 1. The bottom of the mounting part has a through hole, and the roller 2433 is located in the through hole. One end of the connecting shaft 2432 is located on one side of the mounting part and connected to the handwheel 2431. The other end of the connecting shaft 2432 passes through the roller 2433 and is connected to the mounting part. Rotating the handwheel 2431 can drive the roller 2433 to rotate, thereby driving the mounting base 242 to move. The structure is simple and easy to operate.

[0080] Another aspect of this application provides a method for drilling a spherical tank tie rod. This drilling method employs the drilling equipment described above, which includes a drilling device 2 and a position adjustment device 3 connected to each other. The position adjustment device 3 can adjust the position of the drilling device 2 to process the spherical tank tie rod 1 placed in different positions. The drilling method includes the following steps:

[0081] S1. Arrange the drilling device on one side of the spherical tank tie rod 1; specifically, the spherical tank tie rod 1 to be processed can be arranged on the work frame 100 first. Multiple spherical tank tie rods 1 can be arranged radially in sequence on the work frame 100, and the drilling device can be placed near one end of the spherical tank tie rod 1. The drilling device can be placed in front of the work frame 100.

[0082] like Figure 7 As shown, the work frame 100 has a horizontally upward bearing surface 110, on which the spherical tank tie rods 1 are arranged radially. The bearing surface 110 is set to be horizontal, which reduces the restriction on the placement position of the spherical tank tie rods 1.

[0083] like Figure 8As shown, in some embodiments, the work frame 100 is provided with a plurality of limiting protrusions 130 at intervals, and there is a space between two adjacent limiting protrusions 130 suitable for placing the ball tank pull rod 1. In this way, sufficient gap is ensured between two adjacent ball tank pull rods 1, reducing the interference of the ball tank pull rod 1 with the adjacent ball tank pull rod 1 when drilling.

[0084] like Figure 9 As shown, in some embodiments, the work frame 100 is provided with multiple placement areas 140, which are spaced apart along the length of the work frame 100. Each placement area 140 has a downwardly concave arc surface that adapts to the outer surface of the spherical can pull rod 1. The placement areas 140 not only improve the stability of the spherical can pull rod 1 while it rests on the work frame 100, but also ensure sufficient clearance between adjacent spherical can pull rods 1, reducing interference from adjacent spherical can pull rods 1 during drilling.

[0085] In some embodiments, the bearing surface 110 is provided with limiting portions 120 at both ends along the radial direction of the spherical tank tie rod 1. The limiting portions 120 protrude upward from the bearing surface 110, which can prevent the spherical tank tie rod 1 from falling off the bearing surface 110.

[0086] Multiple work frames 100 can be provided, and the multiple work frames 100 are distributed at intervals along the axial direction of the spherical tank tie rod 1. In some embodiments, three work frames 100 can be provided along the axial direction of the spherical tank tie rod 1, and the three work frames 100 are respectively located at both ends and the middle of the spherical tank tie rod 1 to ensure that the spherical tank tie rod 1 can be effectively supported by the work frames 100.

[0087] The drilling device 2 is placed between the position adjustment device 3 and the spherical tank pull rod 1 to be processed, which makes it easier to position the drilling device 2 relative to the spherical tank pull rod 1.

[0088] If the drilling device 2 is used to process the center hole of the spherical tank tie rod 1, then the output end of the drilling device 2 should correspond to the center of the spherical tank tie rod 1 to be processed.

[0089] S2. The drilling device 2 is moved to the position corresponding to one of the spherical tank levers 1 by the position adjustment device 3.

[0090] Specifically, the drilling device 2 can be lifted by the counterweight 324 of the first position adjustment structure 32, and then the front and rear positions can be adjusted by the second position adjustment structure 33, and the left and right positions can be adjusted by the third position adjustment structure 34, so that the drilling device 2 can correspond to the end position of one of the spherical tank pull rods 1.

[0091] S3. Fix the ball tank tie rod 1 to the drilling device 2 and drill a hole. The ball tank tie rod 1 is fixed to the frame 21 by the fixing component 23 on the frame 21. Then, the ball tank tie rod 1 is drilled by the drilling component 22, and the distance between the drilling component 22 and the ball tank tie rod 1 is controlled by the feed component 24, thereby controlling the drilling depth.

[0092] S4. Release the fixation on the spherical tank tie rod 1, and move the drilling device 2 to the position corresponding to the next spherical tank tie rod 1 using the position adjustment device 3. Loosen the restriction of the fixing component 23 on the spherical tank tie rod 1, and then move the second position adjustment structure 33 away from the spherical tank tie rod 1 to disengage the drilling component 22 from the spherical tank tie rod 1. Then, lift the entire drilling device 2 using the first position adjustment structure 32 to remove it from the placement surface for easier movement. Then, through the cooperation of the first position adjustment structure 32, the second position adjustment structure 32, and the third position adjustment structure 34, move the drilling device 2 to the position corresponding to the next spherical tank tie rod 1 to be processed. Repeat the above operation until all spherical tank tie rods 1 have been processed.

[0093] In summary, the drilling equipment provided in this application has a simple structure and can change the working position of the drilling device 2 by means of the position adjustment device 3 when processing the center hole of the spherical tank tie rod, thereby processing different spherical tank tie rods. This drilling equipment improves the processing efficiency of the spherical tank tie rod 1 and shortens the processing cycle of the spherical tank tie rod 1, reducing the production cycle of the spherical tank tie rod 1 to more than 20 pieces per hour. In addition, using this drilling equipment can also reduce the use of large equipment such as boring machines and cranes, reducing the processing cost to one-tenth of the original cost.

[0094] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of this application, and all such substitutions or changes should fall within the protection scope of the appended claims.
