Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a convenient machine for machining large structural flanges. Background Technology

[0002] The processing of large component flanges currently relies mainly on fixed gantry milling machines and mobile equipment. To ensure the flatness requirements of the processing, the gantry milling machine or mobile processing equipment needs to have sufficient rigidity. The gantry and slewing mechanism of large stacker-reclaimers are often ten meters or even larger in size. The resources of fixed equipment that can process them are often scarce, and the requirements for infrastructure are high. The equipment investment is large and the maintenance costs are high. Due to the influence of the foundation, the guide rail foundation may have varying degrees of settlement, which often requires regular inspection and maintenance of the slide rail.

[0003] However, the flange moving processing equipment has a large self-weight. The equipment that can process a 6-meter diameter flange weighs more than ten tons. It has high requirements for the strength of temporary support fixtures, and the adjustment is difficult and time-consuming. Due to the movement of the machine head and the influence of cutting force, the center of gravity of the structure may not be in the center of the structure, resulting in uneven load on the slewing bearing. Wear of the slewing bearing will lead to a decrease in processing accuracy, a shortened maintenance cycle, and unstable processing accuracy. As the processing diameter changes, equipment improvement becomes a necessity. Utility Model Content

[0004] To address the challenge of adjusting flange moving processing equipment, this application provides a convenient machining device for large structural flanges.

[0005] The technical solution adopted in this application for a convenient machining equipment for large structural flanges is as follows:

[0006] A convenient machining device for large structural flanges includes a cantilever arm and an extension base. The cantilever arm is arranged above the extension base and has a rotating platform for driving its rotation. A central column is arranged on the extension base and is rotatably connected to the center of the rotating platform. A rotary fine-tuning mechanism is provided on the extension base. The rotary fine-tuning mechanism includes several set screw blocks and several adjusting bolts. The set screw blocks are arranged in a circumferential array along the outer wall of the central column. Each adjusting bolt corresponds to one of the set screw blocks and is arranged on the set screw blocks, with the head of the adjusting bolt abutting against the outer wall of the central column. A base fine-tuning mechanism is provided on the outer side of the extension base.

[0007] Due to the movement of the machine head and the influence of cutting force, the center of gravity of the structure may not be in the center of the structure, resulting in uneven load on the slewing bearing. Wear of the slewing bearing will lead to a decrease in machining accuracy, a shortened maintenance cycle, and unstable machining accuracy as the machining diameter changes. By adopting the above technical solution, including a cantilever arm and an extension base, the cantilever arm is driven to rotate by the rotating platform, the central column supports the rotating platform, the slewing fine adjustment structure is installed on the extension base, and the base fine adjustment mechanism is installed on the outside of the extension base.

[0008] When adjusting the equipment's center of gravity, based on abnormal phenomena observed during equipment operation, such as increased vibration or unstable operation, a preliminary judgment is made regarding the possible direction of the center of gravity shift. Simultaneously, professional measuring tools are used to further determine the specific direction and extent of the shift. Based on the direction of the shift, the position of the rotary fine-tuning mechanism needs adjustment. If the center of gravity shifts in a certain direction, the adjusting screw and adjusting bolt on the opposite side are adjusted (e.g., if the center of gravity shifts to the left, the adjusting screw and adjusting bolt on the right side are adjusted). Before adjustment, the adjusting bolt on the offset side should be loosened slightly to create a gap between the adjusting screw and the outer wall of the central column (while maintaining the connection between the bolt and the adjusting screw), providing space for subsequent adjustments. Based on the direction of the deviation, the adjusting bolt on the non-offset side (opposite direction of the deviation) is adjusted... Tighten the bolts (to push the center column towards the target direction), and simultaneously loosen the remaining adjusting bolts on the offset side appropriately (to release the reverse pressure), forming a combined force to push the center column. During the adjustment process, closely observe the changes in the equipment's posture. Real-time monitoring can be performed using measuring tools to ensure the accuracy and effectiveness of the adjustment. When the equipment's posture is adjusted to near the ideal state, use a wrench to tighten the adjusting bolts, making the set screw block in close contact with the outer wall of the center column to fix the position of the center column. Based on the equipment's posture and center of gravity offset after adjustment by the rotary fine-tuning mechanism, analyze whether further adjustment through the base fine-tuning mechanism is needed. If the equipment still has a certain degree of center of gravity offset or unstable posture, supplementary adjustment using the base fine-tuning mechanism is required until the equipment's posture is adjusted to the ideal state.

[0009] With the addition of rotary fine-tuning mechanisms and base fine-tuning mechanisms, the center of gravity of the equipment can be precisely adjusted, ensuring a uniform distribution of the slewing bearing load. This significantly reduces vibration and instability caused by center of gravity shift, improves processing accuracy and stability, extends equipment lifespan, reduces wear-related failures and downtime, lowers maintenance frequency and costs, and guarantees the overall economic efficiency of the equipment. Furthermore, it is highly adaptable, meeting diverse processing needs. The range of flange diameters it can process can be infinitely expanded, satisfying the processing requirements of flanges of different sizes. It possesses extremely high versatility and flexibility, is easy to operate, and improves work efficiency.

[0010] Optionally, the rotary fine-tuning mechanism has four sets of set screw blocks and adjusting bolts. The four sets of set screw blocks are arranged in an array along the circumferential direction of the outer wall of the central column, and the two sets of set screw blocks are symmetrically arranged on both sides of the central column.

[0011] By adopting the above technical solution, the rotary fine-tuning mechanism has four sets of set screws and adjusting bolts, with two sets of set screws symmetrically arranged on both sides of the central column. By setting the number and position of the set screws and adjusting bolts, the four sets of set screws are symmetrically arranged on both sides of the central column (such as front and back, left and right), forming a stable four-way support structure. The structural symmetry improves stability and enhances the resistance to eccentric loads. The stress can be dispersed through the coordinated adjustment of the set screws, avoiding local overload.

[0012] Optionally, the base fine-tuning mechanism includes four tooling back plates and four nut base plates. The four nut base plates are arranged in an array along the circumferential direction of the outer wall of the heightening base. The four tooling back plates correspond one-to-one with the four nut base plates. The tooling back plates are arranged on the foundation. Long bolts for adjustment are provided between the tooling back plates and the corresponding nut base plates.

[0013] By adopting the above technical solution, the base fine-tuning mechanism includes four tooling plates and four nut base plates. When the equipment posture and center of gravity shift after adjustment by the rotary fine-tuning mechanism, further adjustment is needed through the base fine-tuning mechanism. If the equipment tilts in a certain direction (such as sinking to the left), the base fine-tuning mechanism on the target side needs to be adjusted to raise the height of the target side. Use a wrench to loosen all the long bolts on the target side appropriately (retain 1-2 turns of thread connection to prevent them from falling off). Select two diagonal long bolts on the target side and tighten them gradually (rotate 1 / 8-1 / 4 turn each time). When tightening, observe the changes in the equipment posture simultaneously to avoid over-adjustment at a single point. If the equipment posture is not fully restored, continue to tighten the other two diagonal long bolts (rotate 1 / 8-1 / 4 turn each time). At the same time, loosen the long bolts on the opposite side (such as the right side) appropriately to release the reverse pressure and form a "push-pull" combined force. During the adjustment process, continuously use measuring tools to monitor the equipment posture and rotary bearing load until the equipment posture reaches the design requirements.

[0014] By setting up a base fine-tuning mechanism, the equipment can quickly adapt to the posture adjustment requirements under different working conditions, reduce modification costs, further realize the fine-tuning of the equipment, and maintain the long-term stable operation of the equipment.

[0015] Optionally, the heightening base is provided with a reference ring for use as a reference for detection and processing, and the reference ring is arranged horizontally on the heightening base.

[0016] By adopting the above technical solution, the reference ring is installed on the raised base. With the setting of the reference ring, the reference ring serves as a reference for testing and processing, ensuring that the installation, debugging and processing of all parts of the equipment are based on the same horizontal plane, eliminating the accumulation of errors caused by inconsistent references, and allowing the testing equipment to be directly aligned with the reference ring for measurement without the need for repeated adjustment of the measurement reference, thus shortening the testing time and improving efficiency.

[0017] Optionally, the heightening base is provided with a plurality of adjusting shims for adjusting the flatness of the reference ring. The plurality of adjusting shims are arranged at the bottom of the reference ring and are arranged in an array along the circumference of the reference ring.

[0018] By adopting the above technical solution, several adjusting shims are installed at the bottom of the reference ring. By adjusting the shims, the flatness of each area of ​​the reference ring can be adjusted independently. By increasing or decreasing the thickness of the shims or adjusting their position, local height differences can be quickly eliminated, ensuring its reliability as a reference for testing and processing.

[0019] Optionally, the cantilever arm is equipped with a laser detection probe for detection, and there may be multiple sets of laser detection probes.

[0020] By adopting the above technical solution, the laser detection probe is installed on the cantilever arm. With the setting of the laser detection probe, the laser detection probe can measure the size, position or surface morphology of the target object without physical contact by emitting a laser beam and receiving the reflected signal. This avoids measurement errors or workpiece damage caused by contact. At the same time, the laser detection probe can monitor the equipment operating status in real time, detect abnormalities in time and issue early warnings, and ensure the stability of equipment operation.

[0021] Optionally, the cantilever arm is equipped with a hydraulic pump station for providing power support.

[0022] By adopting the above technical solution, the hydraulic pump station is installed on the cantilever arm; the setting of the hydraulic pump station realizes efficient power output, meets the needs of complex working conditions, can adapt to harsh working conditions, and improves equipment reliability.

[0023] Optionally, the cantilever arm is provided with a connecting H-beam for installing a hydraulic pump station, the bottom of the connecting H-beam is connected to the cantilever arm, and the hydraulic pump station is connected to the top of the connecting H-beam.

[0024] By adopting the above technical solution, the hydraulic pump station is installed with the cantilever arm by connecting H-beams. The H-beams have an I-shaped cross-section, which has excellent bending and torsional resistance and can withstand the weight of the hydraulic pump station and the vibration load during operation. This avoids local stress concentration in the cantilever arm, ensures long-term operation without loosening, and improves the installation stability of the hydraulic pump station.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. Through the slewing fine-adjustment mechanism and the base fine-adjustment mechanism, the center of gravity of the equipment can be precisely adjusted, so that the load of the slewing bearing is evenly distributed, significantly reducing vibration and instability caused by center of gravity offset, improving processing accuracy and stability, extending the service life of the equipment, reducing failures and downtime caused by wear, reducing maintenance frequency and cost, ensuring the overall economy of the equipment, while being highly adaptable to meet diverse processing needs. The range of flange diameters that can be processed can be infinitely expanded, meeting the processing needs of flanges of different sizes. It has extremely high versatility and flexibility, is easy to operate, and improves work efficiency.

[0027] 2. By setting the number and position of the set screw blocks and adjusting bolts, four sets of set screw blocks are symmetrically arranged in pairs on both sides of the central column (such as front and back, left and right), forming a stable four-way support structure. The structural symmetry improves stability and enhances the resistance to eccentric loads. The stress can be dispersed through the coordinated adjustment of the set screw blocks to avoid local overload.

[0028] 3. By setting a reference ring, the reference ring serves as a reference standard for testing and processing, ensuring that the installation, debugging, and processing of all components of the equipment are based on the same horizontal plane. This eliminates the accumulation of errors caused by inconsistent reference standards, allowing the testing equipment to be directly aligned with the reference ring for measurement without repeatedly adjusting the measurement reference, thus shortening the testing time and improving efficiency.

[0032] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0033] This application discloses a convenient machining device for large structural flanges. (Refer to...) Figure 1The large structural component flange machining equipment includes a cantilever arm 1 and an extension base 2. In this embodiment, the extension base 2 is cylindrical and is arranged on the foundation. The cantilever arm 1 is arranged above the extension base 2. The design of the cantilever arm 1 is due to the variation in the diameter of the structure to be processed. The distance from the processing mechanism to the reassembly center is uncertain, and the specifications of the cantilever arm 1 need to be adjusted according to the size of the structural component.

[0034] Reference Figure 1 A rotating platform 3 is installed on the cantilever arm 1, and a central column 4 is installed on the heightening base 2. The central column 4 is vertically fixed on the heightening base 2, and the top of the central column 4 is rotatably installed at the center of the rotating platform 3. In this embodiment, the cantilever arm 1 is driven to rotate by the rotating platform 3, and the central column 4 plays the role of supporting the rotating platform 3.

[0035] Reference Figure 1 A hydraulic pump station 11 is installed on the cantilever arm 1. In this embodiment, the hydraulic pump station 11 can be selected with a total power of 37Kw, a voltage level of 380V, an oil pump of the Japanese Yuken brand (PV2R3-60), an oil tank volume of 220L, using N46 hydraulic oil, and a flow rate of 75L / min. The pump station has external dimensions of 1200mm*900mm*1420mm and a weight of about 1000 kg (including hydraulic oil).

[0036] Reference Figure 1 A connecting H-beam 12 is installed on the cantilever arm 1, and the connecting H-beam 12 is fixed to the cantilever arm 1 with bolts. At the same time, the hydraulic pump station 11 is fixed to the top of the connecting H-beam 12 with bolts. In this embodiment, the cantilever arm 1 can be equipped with a traveling mechanism and a processing mechanism. The traveling mechanism is fixed to the connecting beam with bolts and can run along the circular track with stepless speed change. The running speed is adjustable and the height can be automatically raised and lowered to ensure smooth operation. The processing mechanism is fixed to the structure with a slide rail and can be driven to slide by a lead screw to meet the requirements of milling flange surfaces. Its hydraulically driven cyclone cutter head is adapted to outdoor environments of -20℃ to 60℃, has multiple clamping methods and cutting depth adjustment functions, and is equipped with a digital depth gauge and remote control operation.

[0037] Reference Figure 1 and Figure 2 A reference ring 8 is installed on the raising base 2. In this embodiment, the reference ring 8 is used as a reference for inspection and processing. The reference ring 8 adopts a chain design, and different numbers of sections can be selected and adjusted to different diameters as needed. The reference ring 8 is horizontally arranged on the raising base 2. At the same time, several adjusting shims 9 are installed on the raising base 2. The adjusting shims 9 are all arranged at the bottom of the reference ring 8, and the adjusting shims 9 are arranged in a sequential array along the circumference of the reference ring 8. The adjusting shims 9 can independently adjust the flatness of each area of ​​the reference ring 8. By increasing or decreasing the thickness of the shims or adjusting their positions, local height differences can be quickly eliminated to ensure its reliability as a reference for inspection and processing.

[0038] Reference Figure 1 A laser detection probe 10 is installed on the cantilever arm 1. In this embodiment, there are multiple laser detection probes 10. The laser detection probes 10 can be installed at the tail end and the end end of the cantilever arm 1. The working principle is that the cantilever arm 1 rotates around the flange surface to be processed for one revolution. The flatness of the entire plane will be fed back by the electronic control system. The electronic control system compares this data with the data of the rotating mechanism and the reference ring 8. Finally, the comparison of this data guides the machine operator to adjust the perpendicularity of the rotating structure to the flange surface to be processed and the parallelism of the reference ring 8 to the flange surface to be processed, so as to ensure that the entire flange surface to be processed can be machined in the future.

[0039] Reference Figure 1 and Figure 2 The heightening base 2 is equipped with a rotary fine-tuning mechanism 5, which includes several set screw blocks 51 and several adjusting bolts 52. The set screw blocks 51 are arranged in a circumferential array along the outer wall of the central column 4, and the adjusting bolts 52 correspond one-to-one with the set screw blocks 51. Preferably, the rotary fine-tuning mechanism 5 has four sets of set screw blocks 51 and adjusting bolts 52. The set screw blocks 51 are symmetrically arranged on both sides of the central column 4 in pairs. The set screw blocks 51 are welded and fixed to the heightening base 2. The adjusting bolts 52 pass through the set screw blocks 51 and are threadedly connected to the set screw blocks 51. The head of the adjusting bolts 52 abuts against the outer wall of the central column 4. The four sets of set screw blocks 51 are symmetrically arranged on both sides of the central column 4 in pairs (such as front and back, left and right), forming a stable four-way support structure. The structural symmetry improves stability and enhances the resistance to eccentric loads. The stress can be dispersed through the coordinated adjustment of the set screw blocks 51 to avoid local overload.

[0040] Reference Figure 1 and Figure 2 Meanwhile, a base fine-tuning mechanism 6 is installed on the outside of the heightening base 2. The base fine-tuning mechanism 6 includes four tooling plates 61 and four nut base plates 62. The four nut base plates 62 are arranged in an array along the circumferential direction of the outer wall of the heightening base 2. The nut base plates 62 are welded and fixed to the heightening base 2. The four tooling plates 61 correspond one-to-one with the four nut base plates 62. The tooling plates 61 are installed on the foundation. At the same time, adjustable long bolts 7 are installed between the tooling plates 61 and the corresponding nut base plates 62. Preferably, there are four long bolts 7, which are distributed at the four corners of the nut base plates 62. This allows the equipment to quickly adapt to the posture adjustment requirements under different working conditions, reduces the modification cost, further realizes the fine-tuning of the equipment, and maintains the long-term stable operation of the equipment.

[0041] The implementation principle of the large structural flange machining convenience equipment in this application embodiment is as follows: When it is necessary to adjust the center of gravity of the equipment, based on the abnormal phenomena that occur during the operation of the equipment, such as increased equipment vibration and unstable operation, the possible direction of the center of gravity shift is initially determined. At the same time, professional measuring tools are used to further determine the specific direction and degree of the center of gravity shift. Based on the direction of the center of gravity shift, the position of the rotary fine adjustment mechanism 5 that needs to be adjusted is determined. If the center of gravity shifts in a certain direction, the set screw block 51 and adjusting bolt 52 on the opposite side of that direction are adjusted (for example, if the center of gravity shifts to the left, the set screw block 51 and adjusting bolt 52 on the right side are adjusted). Before adjustment, the adjusting bolt 52 on the offset side needs to be loosened appropriately to create a gap between the set screw block 51 and the outer wall of the central column 4 (but the connection between the bolt and the set screw block 51 is maintained), providing space for subsequent adjustment. According to the direction of deviation, tighten the adjusting bolt 52 on the non-offset side (opposite direction of deviation) (so that the set screw block 51 pushes the central column 4 to move in the target direction), and at the same time loosen the remaining adjusting bolt 52 on the offset side appropriately (to release the reverse pressure), so as to form a combined force to push the central column 4. During the adjustment process, the posture changes of the equipment should be closely observed. Real-time monitoring can be carried out in conjunction with measuring tools to ensure the accuracy and effectiveness of the adjustment. When the posture of the equipment is adjusted to be close to the ideal state, use a wrench to lock the adjusting bolt 52 so that the set screw block 51 is in close contact with the outer wall of the central column 4, and fix the position of the central column 4. According to the posture of the equipment and the center of gravity offset after the adjustment by the rotary fine adjustment mechanism 5, analyze whether further adjustment is needed through the base fine adjustment mechanism 6. If the equipment still has a certain degree of center of gravity offset or unstable posture, the base fine adjustment mechanism 6 needs to be used for supplementary adjustment.

[0042] If the equipment tilts in a certain direction (e.g., sinks to the left), the base fine-tuning mechanism 6 on the target side needs to be adjusted to raise the height of the target side. Use a wrench to loosen all the long bolts 7 on the target side appropriately (leaving 1-2 turns of thread connection to prevent them from falling off). Select two diagonally opposite long bolts 7 on the target side and tighten them gradually (rotate 1 / 8-1 / 4 turn each time). While tightening, observe the changes in the equipment posture simultaneously to avoid over-adjustment at a single point. If the equipment posture is not fully restored, continue to tighten the other two diagonally opposite long bolts 7 (rotate 1 / 8-1 / 4 turn each time). At the same time, loosen the long bolts 7 on the opposite side (e.g., the right side) appropriately to release the reverse pressure and form a "push-pull" combined force. During the adjustment process, continuously use measuring tools to monitor the equipment posture and slewing bearing load until the equipment posture reaches the design requirements.

[0043] With the addition of rotary fine-tuning mechanism 5 and base fine-tuning mechanism 6, the center of gravity of the equipment can be precisely adjusted, ensuring a uniform distribution of the slewing bearing load. This significantly reduces vibration and instability caused by center of gravity shift, improves processing accuracy and stability, extends equipment lifespan, reduces wear-related failures and downtime, lowers maintenance frequency and costs, and guarantees the overall economic efficiency of the equipment. Furthermore, it is highly adaptable, meeting diverse processing needs. The range of flange diameters it can process can be infinitely expanded, satisfying the processing requirements of flanges of different sizes. It possesses extremely high versatility and flexibility, is easy to operate, and improves work efficiency.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
