Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of large machinery support bases, and particularly relates to a cast steel support base for large machinery. Background Technology
[0002] In the industrial production field, large machinery such as mining machinery, metallurgical equipment, and heavy machine tools have extremely high requirements for the stability, load-bearing capacity, and durability of their support structures due to their large weight, high loads during operation, and complex working conditions. As a key load-bearing component of such machinery, the support base directly bears the weight of the main body of the equipment as well as the impact loads and vibration loads generated during operation. Its performance directly affects the operational safety and service life of the entire mechanical system. Currently, the support bases used in large machinery are mostly cast steel parts. This is because cast steel has high strength, toughness, and wear resistance, and can achieve complex structural shapes through casting processes, meeting the basic requirements of the support base for structural integrity and mechanical performance.
[0003] Existing cast steel support components also have certain limitations in their connection and fit with other mechanical parts. For example, during the connection process, the connecting parts on the support are difficult to align with large machinery, making it difficult to guarantee assembly accuracy. At the same time, additional vibrations are generated during operation, which aggravates the wear and fatigue of the support. Some support components have insufficient buffering and shock absorption performance and cannot effectively absorb the vibration energy generated during the operation of the machinery. This not only affects the operating accuracy of the equipment but also shortens the service life of the support and related components. In addition, in order to facilitate storage, general support components have a small bottom area and a small contact area with the ground, resulting in low support performance. In view of this, we propose a cast steel support component for large machinery. Utility Model Content
[0004] The purpose of this utility model is to provide a cast steel support for large machinery to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a cast steel support for large machinery, comprising:
[0006] The base has a support seat fixedly installed on its top. A sliding groove is provided in the support seat. A sliding column is slidably installed in the sliding groove. An installation block, an installation ring, and several bolts are fixedly installed on the top of the sliding column. A movable plate is slidably installed in the sliding groove and at the bottom of the sliding column. Four damping rods are fixedly installed at the bottom of the sliding groove. The tops of the four damping rods are fixed to the movable plate. A spring is fitted on each of the four damping rods. A collision protection frame is fixedly installed at the bottom of the sliding groove. A rubber pad is fixedly installed on the top of the support seat.
[0007] Four storage slots are provided, all of which are located on the periphery of the base. Extended legs are symmetrically and rotatably installed in the storage slots. Grooves are provided in the base and on the periphery of the eight extended leg pivots. Torsion springs are fitted on the pivots of the extended legs and in the grooves.
[0008] A limiting component, located within the base, is used to limit the movement of the eight extended legs.
[0009] In this technical solution, during installation, personnel can first directly put the support legs of the large machinery onto the mounting block and mounting ring. When the mounting block and mounting ring are inside the support legs of the large machinery, the mounting block and mounting ring can position the sliding column, ensuring that the sliding column will not move when it is fixed, thereby improving assembly accuracy and stability, enhancing the strength of the connection parts, and reducing assembly difficulty.
[0010] During the operation of large machinery, vibrations will occur. At this time, the sliding column will press the moving plate downward. The downward movement of the moving plate will compress the four damping rods and four springs, causing them to contract. Under the damping action of the four damping rods and the rebound force of the four springs, the sliding column can play a good buffering role, reducing the impact of vibration on the support base and related components, ensuring that the support base can play a buffering role, reducing the wear and fatigue of the support base, and thus extending the service life of the support base.
[0011] Meanwhile, before use, the eight extension legs can be released by the limiting components. At this time, under the action of the torsion spring, the torsion spring will drive the extension legs to rotate outward until the extension legs are fully extended. The full extension of the eight extension legs can increase the force-bearing area of the base, thereby making the base more supportive and ensuring that large machinery can be more stable when working.
[0012] In the above technical solution, the limiting component further includes:
[0013] Four rectangular slots are provided, each located within the base and above a separate storage slot. A sliding plate is slidably installed within each rectangular slot. Two limiting blocks are fixedly installed at the bottom of each sliding plate. A limiting slot is provided at the top of the extension leg. The bottom end of each limiting block passes through the bottom of the rectangular slot and extends into the corresponding limiting slot. A pull rod is fixedly installed at the top of the sliding plate. The top end of the pull rod passes through the top of the rectangular slot and is fixedly fitted with a pull ring. Several limiting posts are fixedly installed at the top of the rectangular slot, and springs are fitted onto each limiting post.
[0014] In this technical solution, before use, four pull rings can be pulled in sequence. The pull rings moving upward will drive the pull rod upward, which in turn will drive the sliding plate upward. The upward movement of the sliding plate will compress several springs, causing them to contract. At the same time, the upward movement of the sliding plate will also drive two limit blocks upward until the bottom of the limit blocks moves out of the limit groove. At this point, the limit blocks can release the extension legs from their restraints. Under the torsional force of the torsion spring, the torsion spring will drive the extension legs to rotate outward until the extension legs are fully extended. The full extension of all eight extension legs can increase the force-bearing area of the base, thereby improving the base's support and ensuring greater stability of large machinery during operation.
[0015] In the above technical solution, the bottom end of the limiting block is inclined, the bottom end of the limiting block is inserted into the limiting groove, the pull rod is slidably connected to the rectangular groove and the base, and the two ends of the second spring are tightly welded to the sliding plate and the top of the rectangular groove, respectively.
[0016] In this technical solution, it is ensured that when the extension leg is retracted, the extension leg can press the bottom end of the limiting block, causing the limiting block to move upward, ensuring that the bottom end of the limiting block can be inserted into the limiting groove, ensuring that the pull rod can slide normally in the rectangular groove and the base, and ensuring the structural stability of the second spring.
[0017] In the above technical solution, the mounting ring is further located on the periphery of the mounting block, and a plurality of the bolts are located on the periphery of the mounting ring.
[0018] In this technical solution, the structural stability of the mounting ring, mounting block, and several bolts is ensured.
[0019] In the above technical solution, further, the two ends of the spring are respectively tightly welded to the bottom of the sliding groove and the moving plate, and the two ends of the torsion spring are respectively tightly welded to the extension leg and the inner wall of the groove.
[0020] In this technical solution, the structural stability of spring one is ensured, and the structural stability of the torsion spring is guaranteed.
[0021] In the above technical solution, further, the bottom of the extended leg is flush with the bottom of the base.
[0022] In this technical solution, it is ensured that the extended legs can provide support for the base.
[0023] The beneficial effects of this utility model are:
[0024] 1. The cast steel support for this large machinery, through the installation block, installation ring and sliding column, ensures that the sliding column will not move when it is fixed, thus improving assembly accuracy and stability, enhancing the strength of the connection parts and reducing assembly difficulty.
[0025] 2. The cast steel support for this large machinery, through the installation of a sliding column, and the cooperation of the sliding column, moving plate, damping rod, spring, and support, ensures that the support can play a buffering role, reduce the wear and fatigue of the support, and thus extend the service life of the support.
[0026] 3. The cast steel support for this large machinery, through the setting of limiting components, and the cooperation of the limiting components, extension legs, torsion springs and base, ensures that the bearing area of the base can be increased, thereby making the base more supportive and ensuring that the large machinery can be more stable during operation.

[0042] Example 1:
[0043] Please see Figure 1 - Figure 8 As shown, this embodiment provides a cast steel support for large machinery, comprising:
[0044] A base 1 has a support seat 2 fixedly installed on its top. A sliding groove 3 is provided in the support seat 2. A sliding column 4 is slidably installed in the sliding groove 3. An installation block 5, an installation ring 6, and several bolts 7 are fixedly installed on the top of the sliding column 4. A movable plate 9 is slidably installed in the sliding groove 3 and at the bottom of the sliding column 4. Four damping rods 10 are fixedly installed at the bottom of the sliding groove 3. The tops of the four damping rods 10 are all fixed to the movable plate 9. A spring 11 is sleeved on each of the four damping rods 10. A collision protection frame 12 is fixedly installed at the bottom of the sliding groove 3. A rubber pad 8 is fixedly installed on the top of the support seat 2.
[0045] Four storage slots 13 are provided on the periphery of the base 1. Extended legs 14 are symmetrically and rotatably installed in the storage slots 13. Grooves 15 are provided in the base 1 on the periphery of the pivots of the eight extended legs 14 respectively. Torsion springs 16 are fitted on the pivots of the extended legs 14 and in the grooves 15.
[0046] A limiting component is located within the base 1 and is used to limit the eight extension legs 14.
[0047] During installation, personnel can first directly place the support legs of the large machinery onto the mounting block 5 and mounting ring 6. When the mounting block 5 and mounting ring 6 are placed inside the support legs of the large machinery, the mounting block 5 and mounting ring 6 can position the sliding column 4, ensuring that the sliding column 4 will not move when it is fixed, thus improving assembly accuracy and stability, enhancing the strength of the connection parts, and reducing assembly difficulty.
[0048] During the operation of large machinery, vibrations will occur. At this time, the sliding column 4 will press the moving plate 9 downward. The downward movement of the moving plate 9 will press the four damping rods 10 and the four springs 11 to contract. Under the damping action of the four damping rods 10 and the rebound force of the four springs 11, the sliding column 4 can play a good buffering role, reducing the impact of vibration on the support seat 2 and related components, ensuring that the support seat 2 can play a buffering role, reducing the wear and fatigue of the support seat 2, thereby extending the service life of the support seat 2.
[0049] Meanwhile, before use, the eight extension legs 14 can be released from their limits by the limiting components. At this time, under the torsional force of the torsion spring 16, the torsion spring 16 will drive the extension legs 14 to rotate outward until the extension legs 14 are fully extended. The full extension of the eight extension legs 14 can increase the force-bearing area of the base 1, thereby making the base 1 more supportive and ensuring that the large machinery can be more stable when working.
[0050] Example 2:
[0051] This embodiment provides a cast steel support for large machinery. In addition to the technical solutions described in the above embodiments, it also has the following technical features: the limiting component includes:
[0052] Four rectangular slots 17 are formed inside the base 1 and are located above the four storage slots 13. A sliding plate 18 is slidably installed inside the rectangular slot 17. Two limiting blocks 19 are fixedly installed at the bottom of the sliding plate 18. A limiting groove 20 is formed at the top of the extension leg 14. The bottom end of the limiting block 19 passes through the bottom of the rectangular slot 17 and extends into the corresponding limiting groove 20. A pull rod 21 is fixedly installed at the top of the sliding plate 18. The top end of the pull rod 21 passes through the top of the rectangular slot 17 and is fixedly installed with a pull ring 22. Several limiting posts 23 are fixedly installed at the top of the rectangular slot 17. Springs 24 are sleeved on the limiting posts 23.
[0053] Before use, four pull rings 22 can be pulled in sequence. The pull rings 22 moving upward will drive the pull rod 21 to move upward, and the pull rod 21 moving upward will drive the sliding plate 18 to move upward. The sliding plate 18 moving upward will compress several springs 24 to retract. At the same time, the upward movement of the sliding plate 18 will also drive two limit blocks 19 to move upward until the bottom end of the limit block 19 moves out of the limit groove 20. At this time, the limit block 19 can release the limit on the extension leg 14. At this time, under the torsional force of the torsion spring 16, the torsion spring 16 will drive the extension leg 14 to rotate outward until the extension leg 14 is fully extended. The full extension of all eight extension legs 14 can increase the force-bearing area of the base 1, thereby making the base 1 more supportive and ensuring that the large machinery can be more stable during operation.
[0054] Example 3:
[0055] This embodiment provides a cast steel support for large machinery. In addition to the technical solutions of the above embodiments, it also has the following technical features: the bottom end of the limiting block 19 is inclined, the bottom end of the limiting block 19 is inserted into the limiting groove 20, the pull rod 21 is slidably connected to the rectangular groove 17 and the base 1, and the two ends of the spring 24 are tightly welded to the sliding plate 18 and the top of the rectangular groove 17, respectively.
[0056] Specifically, when the extension leg 14 is retracted, it is ensured that the extension leg 14 can press the bottom end of the limiting block 19, causing the limiting block 19 to move upward, ensuring that the bottom end of the limiting block 19 can be inserted into the limiting groove 20, ensuring that the pull rod 21 can slide normally in the rectangular groove 17 and the base 1, and ensuring the structural stability of the second spring 24.
[0057] Example 4:
[0058] This embodiment provides a cast steel support for large machinery. In addition to the technical solution of the above embodiment, it also has the following technical features: the mounting ring 6 is located on the periphery of the mounting block 5, and several bolts 7 are located on the periphery of the mounting ring 6.
[0059] This ensures the structural stability of the mounting ring 6, the mounting block 5, and several bolts 7.
[0060] Example 5:
[0061] This embodiment provides a cast steel support for large machinery. In addition to the technical solution of the above embodiment, it also has the following technical features: the two ends of the spring 11 are tightly welded to the bottom of the sliding groove 3 and the moving plate 9, respectively; the two ends of the torsion spring 16 are tightly welded to the extension leg 14 and the inner wall of the groove 15, respectively.
[0062] Among these measures, ensuring the structural stability of spring 11 and guaranteeing the structural stability of torsion spring 16 are crucial.
[0063] Example 6:
[0064] This embodiment provides a cast steel support for large machinery. In addition to the technical solutions of the above embodiments, it also has the following technical features: the bottom of the extension leg 14 is flush with the bottom of the base 1.
[0065] Among them, it is ensured that the extension leg 14 can provide support for the base 1.
[0066] Working principle: During installation, personnel can first put the support legs of the large machinery directly onto the mounting block 5 and mounting ring 6. When the mounting block 5 and mounting ring 6 are inside the support legs of the large machinery, the mounting block 5 and mounting ring 6 can position the sliding column 4, ensuring that the sliding column 4 will not move when it is fixed, thus improving assembly accuracy and stability, enhancing the strength of the connection parts, and reducing assembly difficulty.
[0067] During the operation of large machinery, vibrations will occur. At this time, the sliding column 4 will press the moving plate 9 downward. The downward movement of the moving plate 9 will press the four damping rods 10 and the four springs 11 to contract. Under the damping action of the four damping rods 10 and the rebound force of the four springs 11, the sliding column 4 can play a good buffering role, reducing the impact of vibration on the support seat 2 and related components, ensuring that the support seat 2 can play a buffering role, reducing the wear and fatigue of the support seat 2, thereby extending the service life of the support seat 2.
[0068] Meanwhile, before use, the four pull rings 22 can be pulled in sequence. The pull rings 22 moving upward will drive the pull rod 21 to move upward, and the pull rod 21 moving upward will drive the sliding plate 18 to move upward. The sliding plate 18 moving upward will compress several springs 24 to retract. At the same time, the sliding plate 18 moving upward will also drive the two limit blocks 19 to move upward until the bottom end of the limit block 19 moves out of the limit groove 20. At this time, the limit block 19 can release the limit on the extension leg 14. At this time, under the action of the torsion force of the torsion spring 16, the torsion spring 16 will drive the extension leg 14 to rotate outward until the extension leg 14 is fully extended. The full extension of all eight extension legs 14 can increase the force-bearing area of the base 1, thereby making the base 1 more supportive and ensuring that the large machinery can be more stable when working.
[0069] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
