Description

Technical Field

[0001] The utility model relates to a crossbeam structure, in particular to a crossbeam structure of a planetary mixer. Background Art

[0002] The beams of various existing planetary mixers need to be used to install high-speed motors, low-speed motors, and transmission structures including sprockets, bearings, shafts, seals, bolts and other parts. An independent sprocket box for installing the transmission structure needs to be placed inside the beam (such as Figure 1 (As shown), the crossbeam also requires appropriate structural components to meet the required crossbeam strength. These components must be positioned as far as possible to accommodate the sprocket box, placing additional constraints on the placement of these components within the crossbeam. The placement of these components within the crossbeam also limits the installation dimensions of the sprocket box. The limited internal space within the sprocket box prevents large sprockets, significantly limiting the placement of high-torque transmission gear trains. Furthermore, the sprocket box itself is complex, making its manufacture difficult and costly. Summary of the Invention

[0003] The technical problem to be solved by the utility model is: to provide a planetary mixer beam structure, which omits the independent sprocket box and adopts two plates, namely a transmission part installation and positioning bottom plate and a transmission part installation and positioning top plate, to replace the function of the sprocket box, while optimizing the arrangement of the internal structural parts of the beam, thereby increasing the operating space inside the beam, simplifying the structure and reducing costs.

[0004] The technical solution to solve the above technical problems is: a planetary mixer beam structure, including a beam body, the beam body including a beam bottom plate and a beam side plate, two partition plates are arranged in the beam body, the partition plates divide the interior of the beam into the front and rear of the beam, a transmission part mounting hole is opened on the beam bottom plate at the front of the beam, a transmission part mounting positioning bottom plate is installed in the transmission part mounting hole, a transmission part mounting positioning top plate is fixed in the beam body above the transmission part mounting hole by two support plates, and only one power device mounting hole is opened on the beam bottom plate at the rear of the beam.

[0005] Furthermore, a reinforcing connecting plate is fixed between the support plate and the beam side plate.

[0006] Furthermore, transverse reinforcing plates are fixed to the bottom plates of the crossbeam on both sides of the power device mounting hole at the rear of the crossbeam, and longitudinal reinforcing rods are provided between the two ends of the transverse reinforcing plates and the side plates of the crossbeam.

[0007] Furthermore, the crossbeam side panels include a front side panel and a rear side panel for mounting a power unit, and the thickness of the rear side panel is 20-40 mm.

[0008] Due to the adoption of the above technical solution, the present invention has the following beneficial effects:

[0009] 1. A separate, complex sprocket case is no longer required within the crossbeam. The mounting surface and bolt holes for the sprocket case no longer need to be separately machined during crossbeam fabrication. By omitting the sprocket case, two plates—a bottom plate for mounting and positioning transmission components and a top plate for mounting and positioning transmission components—replace the sprocket case. This allows the space within the crossbeam to be directly allocated as a large area for the transmission gear train. By eliminating the complex sprocket case, manufacturing complexity and costs are reduced.

[0010] 2. Using two plates to replace the sprocket box can not only maximize the installation space, but also strengthen the structure at this position through support plates and reinforcing connecting plates, further improving the rigidity of the front part of the beam. It can also be welded in one step, further reducing the cost of the entire beam structure.

[0011] 3. After the rigidity of the front part of the beam is enhanced, the vibration transmitted to the beam by the moving parts installed in the front part of the beam will be reduced, and some structural parts that enhance the suppression of vibration can be reduced in the rear part of the beam, that is, the structural parts in the rear part of the beam can be simplified.

[0012] The technical features of the beam structure of a planetary mixer of the present invention will be further described below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] A planetary mixer beam structure, such as Figure 2-Figure 5 As shown, the crossbeam comprises a main body, comprising a crossbeam base plate 1 and crossbeam side plates 2. Two partition plates 7 are symmetrically arranged on either side of the crossbeam body and fixedly connected to the crossbeam base plate 1 and the crossbeam side plates 2. The partition plates 7 divide the interior of the crossbeam into a front portion and a rear portion. A transmission component mounting hole 101 is formed in the crossbeam base plate 1 at the front of the crossbeam. A transmission component mounting and positioning base plate 3 is mounted within the transmission component mounting hole 101. A transmission component mounting and positioning top plate 5 is fixed to the crossbeam body above the transmission component mounting hole via two support plates 6. A transmission structure mounting space is formed between the transmission component mounting and positioning base plate 3 and the transmission component mounting and positioning top plate 5 for mounting a transmission structure including a sprocket, replacing the function of the original independent sprocket box. This space can be significantly larger than the original sprocket box, which can improve the load-bearing capacity of the transmission structure design. Furthermore, the structural components forming this space can further strengthen the internal structure of the crossbeam, thereby improving the load-bearing capacity of the crossbeam. The crossbeam bottom plate 1 at the rear of the crossbeam has only one power unit mounting hole 102 for mounting a low-speed motor and reducer. The crossbeam side panels 2 include a front panel 21 and a rear panel 22 for mounting the power unit. The rear panel has a thickness of 20-40 mm. This embodiment only has one power unit mounting hole 102. Compared to existing crossbeam structures that have two power unit mounting holes, this embodiment saves one hole drilling operation. The saved drilling cost can be used to thicken the rear panel 22 for mounting a high-speed motor.

[0021] In this embodiment, the support plate 6 is fixedly connected to the crossbeam bottom plate 1, the partition plate 7 and the front side plate 21 of the crossbeam side plate.

[0022] In this embodiment, a reinforcing connecting plate 4 is fixed between the support plate 6 and the crossbeam side plate 2. The reinforcing connecting plate 4 is fixedly connected to the crossbeam bottom plate 1, the support plate 6, and the crossbeam side plate 2. Transverse reinforcing plates 9 are fixedly connected to the crossbeam bottom plate 1 on both sides of the power unit mounting hole 102 at the rear of the crossbeam. The transverse reinforcing plates 9 are fixedly connected to the crossbeam bottom plate 1, the partition plate 7, and the rear side plate 22 of the crossbeam side plate. A low-speed motor and reducer mounting plate 10 is provided on one of the transverse reinforcing plates 9. Longitudinal reinforcing rods 8 are also provided between the ends of the transverse reinforcing plates 9 and the crossbeam side plates 2. The longitudinal reinforcing rods 8 are fixedly connected to the crossbeam bottom plate 1 and the crossbeam side plates 2.

[0023] In this embodiment, the structural parts inside the beam can be welded and processed together when the beam is manufactured, which improves the structural strength of the beam while further ensuring the strength of the transmission gear train installation space and a larger installation space.

[0024] Usage status:

[0025] The transmission components such as sprockets, bearings, shafts, seals, etc. are installed on the transmission parts installation and positioning base plate 3 and the transmission parts installation and positioning top plate 5, the low-speed motor and reducer are installed in the power unit installation hole 102, and the high-speed motor is installed on the rear side plate 22.
