Description

Technical Field

[0001] This application relates to the field of hoisting technology, and in particular to a high-speed hoisting machine. Background Technology

[0002] A hoist is a conveying device that primarily uses a power machine to drive a flexible component and the material being transported to move up and down, thereby achieving the vertical transport of materials. A hoist includes a support frame, a lifting platform, a chain, and a drive motor. The drive motor is mounted on the support frame, and the chain is connected to the lifting platform; the chain descends under the drive motor's influence, causing the lifting platform to rise or fall.

[0003] The production of wheel hubs requires multiple processes. Typically, wheel hub blanks are placed on a conveyor belt for transport, and the blanks are processed step by step during the transport process.

[0004] In related technologies, the production line for processing wheel hubs is limited by the length of the factory building, so part of the production line is set up on the second or even third floor of the factory building. In order to facilitate the transportation of wheel hubs from the first floor to the production line upstairs, a hoist is usually installed on one side of the production line. After the wheel hubs are conveyed and processed by the production line downstairs, they are conveyed to the lifting platform. Then, the drive motor drives the chain to move to transport the wheel hubs located on the lifting platform to the production line upstairs for further processing.

[0005] Regarding the aforementioned technologies, when the factory building has a high ceiling, the distance between the lifting platform and the upper production line is also long, and the chain length is also long. Consequently, the chain is more prone to swaying during the process of lifting the platform, resulting in poor stability. Summary of the Invention

[0006] To improve the stability of the hoist during the conveying process, this application provides a high-speed hoist, employing the following technical solution: A high-speed hoist includes: a frame extending in a vertical direction; The lifting platform is slidably installed on the frame in a vertical direction; A drive assembly, mounted on the frame, is used to drive the lifting platform to move up and down; The guide assembly includes a guide rail connected to the frame and a slider connected to the lifting platform and slidably mounted on the guide rail; An adjustment component, mounted on the frame, is used to adjust the verticality of the guide rail; The adjustment components are provided in multiple sets, and the multiple sets of adjustment components are arranged at intervals along the vertical direction on the frame.

[0007] To ensure the verticality of the guide rail on the frame, the guide assembly also includes a profile with a nut groove for mounting a T-nut. The nut groove extends through the profile along its extension direction and is spaced out in multiple circumferentially on the profile. The guide rail is mounted at one of the nut grooves.

[0008] To facilitate the adjustment of the profile's verticality, the adjustment component is located on the side of the profile away from the guide rail; The adjustment assembly includes a vertical adjustment plate for adjusting the verticality of the profile and a horizontal adjustment plate for adjusting the horizontal alignment of the profile. One side of the horizontal adjustment plate is connected to the profile, and the other side is connected to the vertical adjustment plate. The horizontal adjustment plate and the vertical adjustment plate move synchronously. The vertical adjustment plate is connected to the frame.

[0009] To facilitate adjustment of the horizontal alignment of the profile, a horizontal adjustment hole is provided on the horizontal adjustment plate. The horizontal adjustment hole extends horizontally and is connected to one of the nut grooves on the side of the profile away from the guide rail.

[0010] In order to adjust the height of both sides of the profile, the adjustment assembly also includes an adjusting threaded sleeve and a clamping nut, wherein the clamping nut is sleeved and threadedly installed on the adjusting threaded sleeve; The outer wall of the frame opposite to the vertical adjustment plate has a nut hole for the adjusting threaded sleeve to pass through. The diameter of the nut hole is larger than the outer diameter of the adjusting threaded sleeve. The vertical adjustment plate has an insertion hole that communicates with the nut hole for the adjusting threaded sleeve to be inserted and threadedly connected. The clamping nut and the vertical adjustment plate clamp the frame. Two adjusting threaded sleeves are arranged at intervals along the horizontal direction, and two clamping nuts are also provided. The two clamping nuts are respectively installed on the two adjusting threaded sleeves. There are two nut holes and two insertion holes. The two nut holes correspond one-to-one with the two adjusting threaded sleeves, and the two insertion holes correspond one-to-one with the two nut holes.

[0011] To facilitate adjustment of the profile in another horizontal direction, the adjustment assembly also includes a tension bolt that is inserted into and threadedly connected to the adjustment threaded sleeve. The horizontal adjustment plate has a connection hole for the tension bolt to be inserted and threadedly connected.

[0012] To ensure the stability of the frame and the ease of installation of the drive components, the frame includes a welding frame and a top connecting frame. The welding frame is a square column-shaped frame. The lifting platform slides inside the welding frame. The top connecting frame is installed on the top of the welding frame, and the drive components are installed on the top connecting frame. The top connecting frame is equipped with a height adjustment component for adjusting the flatness between the top connecting frame and the welding frame.

[0013] To ensure the flatness between the welding frame and the top connecting frame after connection, four sets of height adjustment components are provided. The four sets of height adjustment components are located at the four right angles of the top of the welding frame. Each height adjustment component includes an adjusting sleeve installed at the bottom of the top connecting frame and an adjusting bolt inserted and threaded into the adjusting sleeve. The top of the welding frame has bolt holes for the adjusting bolt to be inserted and threaded.

[0014] To enable automatic loading and unloading of wheel hub blanks, the lifting platform includes a lifting frame, a conveyor roller rotatably mounted on the lifting frame, and a drive motor that drives the conveyor roller to rotate.

[0015] The frame is equipped with a limiting baffle to limit the movement of the wheel hub blank.

[0016] In summary, this application includes at least one of the following beneficial technical effects: When the lifting platform is raised or lowered, the guide component not only guides the lifting platform but also limits its movement in other directions, making it less prone to large-scale shaking during lifting and lowering, thus making the lifting platform more stable during lifting and transportation. During installation, since the nut groove is integrally formed on the profile before it leaves the factory, the verticality accuracy of the nut groove extension is relatively high. The verticality of the guide rail after it is installed on the profile is also relatively high. In addition, after the profile is installed on the frame, the horizontal position can be adjusted by adjusting the adjustment holes on the horizontal adjustment plate, and the gap between the profile and the frame can be adjusted by adjusting the threaded sleeve. This improves the verticality of the profile after it is installed on the frame, making the lifting platform more stable and smooth during transportation and less prone to jamming. Because the diameter of the nut hole is larger than the outer diameter of the adjusting threaded sleeve, the adjusting threaded sleeve can make multi-directional micro-adjustments within the nut hole, further improving the accuracy of adjusting the verticality of the profile.

[0031] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0032] Example 1: This application discloses a high-speed hoist. (Refer to...) Figure 1 and Figure 2 The high-speed hoist includes a frame 1, a lifting platform 2, a drive assembly 3, a guide assembly 4, and an adjustment assembly 5. The frame 1 extends vertically. The drive assembly 3 is mounted on the top of the frame 1 to drive the lifting platform 2 to rise and fall. The guide assembly 4 is mounted on the frame 1 and connected to the lifting platform 2, thereby improving the stability of the lifting platform 2 during lifting. The adjustment assembly 5 is mounted on the frame 1 to adjust the verticality of the guide assembly 4, further improving the stability of the lifting platform 2 during lifting. Multiple sets of adjustment assemblies 5 are provided, and these sets are arranged at intervals along the extension direction of the frame 1.

[0033] In addition, in this embodiment, the height of the frame 1 is preferably ten meters, and the lifting platform 2 reaches a rising speed of two meters per second under the action of the drive component 3. The frame 1 extends from the first floor to the second floor of the factory. The conveyor belt on the production line on the first floor transports the products to the lifting platform 2. After the lifting platform 2 rises to the second floor, it unloads the products onto the conveyor belt on the production line on the second floor for transmission.

[0034] Reference Figure 2 and Figure 3 The frame 1 includes a welding frame 11 and a top connecting frame 12. The top connecting frame 12 is mounted on top of the welding frame 11, and the drive assembly 3 is mounted on the top connecting frame 12. The welding frame 11 is a square column-shaped frame, and the lifting platform 2 slides inside the welding frame 11.

[0035] The welding frame 11 includes vertical square tubes 13 and horizontal square tubes 14. Each vertical square tube 13 is a single, integrally formed square tube. In this embodiment, four vertical square tubes 13 are preferably arranged in a right-angled square configuration. The horizontal square tubes 14 are located between two adjacent vertical square tubes 13, with both ends welded to the two vertical square tubes 13. Multiple horizontal square tubes 14 are provided, spaced apart along the extension direction of the vertical square tubes 13, with multiple horizontal square tubes 14 between every two adjacent vertical square tubes 13. This design ensures that even if materials fall from the lifting platform 2 during material transport, they will fall into the interior of the welding frame 11, preventing them from hitting personnel or equipment outside the welding frame 11.

[0036] Reference Figure 3 and Figure 4 Each of the four vertical square tubes 13 has a top plate 15 welded to its top, and the bottom of the top connecting frame 12 has four base plates 16 corresponding to the top plates 15 welded to their bottoms. Both the top plates 15 and the base plates 16 are square plates. Each base plate 16 is equipped with four sets of height adjustment components 17, which are located at the four right angles of the base plate 16. These components are used to adjust the flatness between the top connecting frame 12 and the welding frame 11, making the fit between the drive component 3 and the guide component 4 more precise. The following explanation uses one set of height adjustment components 17 as an example.

[0037] Reference Figure 4 and Figure 5 The height adjustment assembly 17 includes an adjusting sleeve 171 and an adjusting bolt 172. A threaded hole is formed in the top of the base plate 16, and the adjusting sleeve 171 is inserted into the threaded hole and threaded onto the base plate 16. The side of the adjusting sleeve 171 closest to the top plate 15 can pass through the threaded hole and abut against the top plate 15, thereby adjusting the gap between the top plate 15 and the base plate 16. The adjusting bolt 172 is inserted into the adjusting sleeve 171 and threadedly connected to it. The end of the adjusting bolt 172 closest to the top plate 15 protrudes from the adjusting sleeve 171. A threaded groove is formed in the top of the top plate 15 for the adjusting bolt 172 to be inserted and threadedly connected, thus connecting the welding frame 11 and the top connecting frame 12.

[0038] Reference Figure 3 and Figure 6The lifting platform 2 includes a lifting frame 21, conveyor rollers 22, and a drive motor 23. The conveyor rollers 22 are rotatably mounted on the top of the lifting frame 21 for loading and unloading products. Multiple conveyor rollers 22 are arranged at intervals along a horizontal direction. The drive motor 23 is mounted on the lifting frame 21 and located below the conveyor rollers 22. A drive gear is mounted on the motor shaft of the drive motor 23, and a drive chain 32 is fitted onto the drive gear. The drive chain 32 is fitted onto the multiple conveyor rollers 22. Thus, the drive motor 23, mounted in both forward and reverse directions, drives the conveyor rollers 22 to rotate in both directions, thereby achieving the loading and unloading of materials.

[0039] A limit baffle 24 is bolted to the lifting frame 21. When the material is loaded, it will be transported to the conveyor roller 22. The conveyor roller 22 will drive the material to move inward. When the material moves to the position of the limit baffle 24, the limit baffle 24 will limit the movement of the material, so that the material will completely detach from the previous conveyor belt.

[0040] Reference Figure 2 and Figure 6 The drive assembly 3 includes a geared motor 31, a chain 32, and a driven sprocket 33. The geared motor 31 is mounted on the top of the top connecting frame 12, and the chain 32 is located inside the welding frame 11 and on one side perpendicular to the horizontal conveying direction of the lifting platform 2. A drive sprocket 34 is mounted on the geared motor 31, and the driven sprocket 33 is located below inside the welding frame 11 and is rotatably mounted on the welding frame 11. The lifting platform 2 is located between the drive sprocket 34 and the driven sprocket 33. The chain 32 is sleeved on the drive sprocket 34 and the driven sprocket 33, and both the drive sprocket 34 and the driven sprocket 33 are engaged with the chain 32. The lifting frame 21 is connected to the chain 32 by screws, thereby realizing lifting.

[0041] The system includes two chains 32, located on opposite sides of the vertical lifting platform 2 in the loading and unloading direction. Because there are two chains 32, two drive sprockets 34 and two driven sprockets 33 are also provided. This ensures the synchronization of the lifting platform 2 during lifting.

[0042] Reference Figure 3 and Figure 7 There are two sets of guide components 4, located on either side of the two chains 32. The two sets of guide components 4 have the same structure; the following explanation uses one set of guide components 4 as an example.

[0043] The guide assembly 4 includes a guide rail 41, a slider 42, and a profile 43. The profile 43 is located inside the welding frame 11 and is mounted on multiple horizontal square tubes 14 on the same side via an adjustment assembly 5. The guide rail 41 is mounted on the profile 43, the slider 42 is slidably mounted on the guide rail 41, and the lifting frame 21 is bolted to the sliding block. Since a ten-meter profile 43 and guide rail 41 are difficult to process, in this embodiment, to ensure verticality, two profiles 43 are spliced ​​together vertically; similarly, two guide rails 41 are also spliced ​​together vertically, and the two guide rails 41 are respectively mounted on two profiles 43. Fixing plates are bolted to the two side walls of the two profiles 43, perpendicular to the guide rails 41, thus connecting the two profiles 43 together via the fixing plates.

[0044] Reference Figure 7 The profile 43 has nut grooves 431 on its sidewalls for placing T-nuts. The nut grooves 431 are integrally machined during the production of the profile 43 and extend along the extension direction of the profile 43 (this is prior art, and is the case for every model of profile 43). Multiple nut grooves 431 are spaced apart on each sidewall of the profile 43. The guide rail 41 is fixed to the profile 43 by bolts and T-nuts installed in the nut grooves 431.

[0045] Combination Figure 2 Reference Figure 8 and Figure 9 In this preferred embodiment, an adjustment component 5 is installed on each horizontal square tube 14 on the side where the profile 43 is located. The adjustment component 5 is located on the side of the profile 43 away from the guide rail 41. Multiple sets of adjustment components 5 have the same structure. The following description uses one set of adjustment components 5 as an example.

[0046] The adjusting assembly 5 includes a vertical adjusting plate 51, a horizontal adjusting plate 52, an adjusting threaded sleeve 53, a clamping nut 54, and a tensioning bolt 55. The horizontal adjusting plate 52 is connected to the profile 43 for adjusting its horizontal position; the vertical adjusting plate 51, in conjunction with the adjusting threaded sleeve 53, adjusts the height of the profile 43. The adjusting threaded sleeve 53 is threaded onto the vertical adjusting plate 51, and the clamping nut 54, in conjunction with the vertical adjusting plate 51, clamps it onto the horizontal square tube 14. The tensioning bolt 55 is inserted into the adjusting threaded sleeve 53 and threadedly connected to it. The connecting bolt is connected to the horizontal adjusting plate 52, thus connecting the vertical adjusting plate 51, the horizontal adjusting plate 52, and the adjusting threaded sleeve 53 together.

[0047] Combination Figure 8 Reference Figure 9 and Figure 10In this embodiment, two adjusting threaded sleeves 53 are preferably arranged at intervals along the extension direction of the transverse square tube 14, and two clamping nuts 54 and two tensioning bolts 55 are also provided; the two clamping nuts 54 are respectively installed on the two adjusting threaded sleeves 53; the two tensioning bolts 55 are respectively installed inside the two adjusting threaded sleeves 53.

[0048] The outer wall of the horizontal square tube 14 has a nut hole 141 for the adjusting threaded sleeve 53 to pass through. Since there are two adjusting threaded sleeves 53, there are also two nut holes 141. The vertical adjusting plate 51 is located inside the welding frame 11 and fits against the horizontal square tube 14. The diameter of the nut hole 141 on the side away from the vertical adjusting plate 51 is larger than the outer diameter of the clamping nut 54, and the diameter of the nut hole 141 on the side closer to the vertical adjusting plate 51 is smaller than the outer diameter of the clamping nut 54 but larger than the outer diameter of the adjusting threaded sleeve 53. Thus, the adjusting threaded sleeve 53 can be slightly moved and adjusted at multiple angles within the nut hole 141. The clamping nut 54 can be hidden inside the horizontal square tube 14 and is not easily rotated to avoid loosening. The clamping nut 54 and the vertical adjusting plate 51 are clamped onto the horizontal square tube 14.

[0049] Combination Figure 8 Reference Figure 9 and Figure 10 In this embodiment, the clamping nut 54 is preferably an external hexagonal nut. In order to facilitate rotation when the clamping nut 54 is located inside the horizontal square tube 14, the end of the clamping nut 54 away from the vertical adjustment plate 51 is provided with two circumferentially spaced drive grooves 541. Then, the matching tool can be inserted into the two drive grooves 541 to apply force to rotate the clamping nut 54.

[0050] The vertical adjustment plate 51 has a socket 511 for the threaded sleeve 53 to pass through and be threadedly connected. The socket 511 is connected to the nut hole 141. The end of the threaded sleeve 53 near the horizontal adjustment plate 52 passes through the vertical adjustment plate 51 and abuts against the horizontal adjustment plate 52, thereby adjusting the gap between the vertical adjustment plate 51 and the horizontal adjustment plate 52, and thus adjusting the gap between the profile 43 and the corresponding horizontal square tube 14.

[0051] The horizontal adjustment plate 52 has an adjustment hole 521 that communicates with the nut groove 431 on the side of the profile 43 facing away from the guide rail 41. The adjustment hole 521 extends horizontally. After the bolt passes through the adjustment hole 521, it will cooperate with the T-nut to connect the horizontal adjustment plate 52 to the profile 43. The verticality of the profile 43 in the horizontal direction can be adjusted through the adjustment hole 521.

[0052] The horizontal adjustment plate 52 has a connecting hole 522 that communicates with the insertion hole 511. The end of the tension bolt 55 near the horizontal adjustment plate 52 protrudes out of the adjusting threaded sleeve 53, is inserted into the connecting hole 522, and is threadedly connected to the horizontal adjustment plate 52.

[0053] The implementation principle of a high-speed lifting machine in this application embodiment is as follows: Since the lifting platform 2 lifts at a relatively fast speed and at a relatively high height, when the driving component 3 drives the lifting platform 2 to lift, the guide rail 41 and the slider 42 play a guiding role for the lifting platform 2 and limit its swaying in other directions.

[0054] In addition, due to the height of the frame 1, both the accuracy and verticality of the guide rail 41 must be ensured during installation. This prevents the lifting platform 2 from jamming during lifting and makes the conveying more stable. Specifically, the horizontal alignment at different positions can be adjusted using the adjustment hole 521 on the horizontal adjustment plate 52. Rotating the adjusting threaded sleeve 53 can change the gap between the horizontal adjustment plate 52 and the vertical adjustment plate 51, thereby adjusting the distance between the profile 43 and the transverse square tube 14 at different positions. Since the welding of the transverse square tube 14 is usually done manually, there will inevitably be slight height differences at both ends of the transverse square tube 14. However, the diameter of the nut hole 141 is larger than the outer diameter of the adjustable threaded sleeve, allowing the adjusting threaded sleeve 53 to make multi-directional micro-adjustments within the nut hole 141, further improving the accuracy of adjusting the verticality of the profile 43.

[0055] Secondly, since the top connecting frame 12 and the welding frame 11 are not integrally welded but spliced ​​together, and the geared motor 31 is installed on the top connecting frame 12, multiple sets of height adjustment components 17 are provided at the connection between each vertical square tube 13 and the top connecting frame 12. This allows for adjustment of the flatness of the connection between the top connecting frame 12 and the four vertical square tubes 13, making the connection between the top connecting frame 12 and the welding frame 11 more flat. Consequently, the geared motor 31 is less likely to deviate, and the drive is smoother.

[0056] Example 2: Refer to Figure 11 The difference between this embodiment and Embodiment 1 is that a groove 432 is provided on one side of the guide rail 41 mounted on the profile 43. The groove 432 communicates with one of the nut grooves 431, and the guide rail 41 is partially installed in the groove 432 to form a preliminary positioning. The groove 432 is integrally formed before the profile 43 leaves the factory, so the extension direction of the groove 432 is relatively straight and the precision is high. Consequently, the guide rail 41 will also be relatively straight after it is installed on the profile 43.

[0057] The guide rail 41 has an integrally formed positioning groove on the side near the profile 43, and the bottom of the groove has an integrally formed positioning strip that can be inserted into the positioning groove.

[0058] Reference Figure 12 In the two guide rails 41, the lower guide rail 41 has a positioning groove 411 at the top, and the upper guide rail 41 has a positioning post 412 integrally formed at the bottom that inserts into the positioning groove 411. This makes the splicing of the two guide rails 41 more precise, thereby improving the flatness of the spliced ​​two guide rails 41 and allowing the slider 42 to move smoothly from one guide rail 41 to the other guide rail 41.

[0059] Reference Figure 13 On one side where the vertical square tube 13 connects to the horizontal square tube 14, a positioning groove 131 is machined on a non-standard lathe for the end of the horizontal square tube 14 to be inserted. The positioning groove 131 is not connected to the interior of the horizontal square tube 14. The two ends of the horizontal square tube 14 are respectively inserted into the corresponding positioning grooves 131 on the two vertical square tubes 13 before welding, thereby improving the levelness of the horizontal square tube 14 after installation.

[0060] 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.
