DETAILED DESCRIPTION
[0022] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.
[0023] Reference Figure 1 and Figure 2 The embodiment of the present disclosure provides a support device, including an upper support 1 and a lower support 2, wherein the upper support 1 and the lower support 2 are assembled and sleeved together along their own axial direction, and illustratively, the upper support 1 and the lower support 2 are welded and connected, or the upper support 1 and the lower support 2 are integrally formed. In addition, the support device also includes a support seat 3, a first elastic member 5 and a base 4, wherein, considering the assembly position and connection relationship of each structure, the lower support 2 is sleeved under the upper support 1, the support seat 3 is sleeved under the lower support 2, and at least partially extends out of the bottom of the lower support 2, the first elastic member 5 is located in the lower support 2, and is connected between the upper support 1 and the support seat 3, the support seat 3 extends into the base 4, and is sleeved inside the base 4, and a safety height gap 7 is left between the bottom surface of the lower support 2 and the base 4.
[0024] In this way, by using the support device of the embodiment of the present disclosure, in the long axis assembly scenario, it can not only add a fulcrum, but also reduce the long axis disturbance during the rotation of the long axis. The flexible component of the first elastic part 5 is used to reduce the impact force, so that the bottom support has a radial compensation function and protects the long axis. In addition, the application of the first elastic part 5 has a shock-absorbing effect and avoids vibration interference.
[0025] The specific scheme of the supporting device is further described, and the supporting device also includes a connecting chuck 6, which is clamped at the connection between the upper support 1 and the lower support 2. The connecting chuck 6 adopts a standard device, and different types of connecting chucks 6 can be selected according to the radial dimensions of the upper support 1 and the lower support 2. The connecting chuck 6 can provide a clamping force in the radial direction for the connection between the upper support 1 and the lower support 2 and the rotating shaft. At the same time, it is very convenient to disassemble the connecting chuck 6, which is convenient for assembling and disassembling the rotating shaft and the supporting device, and can be extended to the bottom of the rotating tank for assembly and disassembly.
[0026] It should be noted that the use of the connecting chuck 6 in the embodiment of the present disclosure can be understood as the use of a chuck interface between the upper support 1 and the lower support 2, which is convenient for disassembly and assembly operations on the one hand, and simple and practical on the other hand, and can quickly install and replace wearing parts.
[0027] In addition, the upper support 1 is composed of two parts, specifically, the upper support 1 includes a first shaft 11 and a second shaft 12 connected to the lower part of the first shaft 11, the radial dimension of the second shaft 12 is larger than the radial dimension of the first shaft 11, and the connection between the first shaft 11 and the second shaft 12 forms a first step 13; the support device also includes a bearing 8, and the bearing 8 is sleeved on the first step 13. In this way, the upper support 1 and the lower support 2 of the support device can be rotated with the rotating shaft through the bearing 8.
[0028] Exemplarily, the first shaft body 11 and the second shaft body 12 both adopt a hollow shaft structure or a hollow tube structure.
[0029] For example, the bearing 8 is an angular contact ball bearing 8, which can bear not only axial force but also radial force. The shaft of the bearing 8 mounted on the upper support 1, that is, the connection between the first shaft body 11 and the second shaft body 12, is fixed by a shaft shoulder and a bearing 8 ring.
[0030] Specifically, the lower support 2 includes a third shaft body 21 and a fourth shaft body 22 extending from the top surface of the third shaft body 21, and the connection chuck 6 is sleeved at the connection between the fourth shaft body 22 and the second shaft body 12. In this way, it is easy to assemble and disassemble.
[0031] Exemplarily, the outer periphery of the top surface of the fourth shaft body 22 and the outer periphery of the bottom surface of the second shaft body 12 are both extended with edge structures 23, and the connecting chuck 6 is sleeved on the edge structure 23. In this way, with the edge structure 23 and the connecting chuck 6, the assembly and disassembly operations of the upper support 1 and the lower support 2 are more convenient.
[0032] Exemplarily, the side surface of the fourth shaft body 22 has at least one through hole 221 along its radial direction, so that the first elastic member 5 is installed in the lower support 2, and the lower spring seat has an observation hole, so that the force condition of the first elastic member 5 can be observed in real time.
[0033] Specifically, the support seat 3 includes a first body 31 and a second body 32 protruding from the top surface of the first body 31. A mounting hole 33 is provided between the second body 32 and the first body 31 in the axial direction. The lower support 2 is installed on the base 4 through the positioning member and the mounting hole 33. Among them, the first body 31 adopts a flat plate structure, and the second body 32 adopts a columnar structure. In actual assembly, the first body 31 can be inserted into the base 4 for clamping, and the first elastic member 5 is pressed and connected between the bottom surface of the fourth shaft 22 and the top surface of the second body 32. In this way, the support seat 3 and the base 4 are relatively immovable, and the upper support 1 and the lower support 2 can form a buffer force that reciprocates in the vertical direction relative to the support seat 3 under the setting of the first elastic member 5.
[0034] Specifically, the radial dimension of the first body 31 is greater than the radial dimension of the second body 32, and a safety height gap 7 is left between the top surface of the first body 31 and the bottom surface of the third shaft body 21. In this way, when the lower support 2 moves back and forth in its own axial direction relative to the support seat 3, it will not interfere with the support seat 3, which can also be further understood as facilitating the release of stress when the entire body is subjected to radial impact force.
[0035] Considering the actual installation scenario of the support device, a reinforcing rib structure 41 is provided around the base 4 to enhance the support strength of the base 4 .
[0036] In summary, the support device using the disclosed embodiment is suitable for occasions where the long axis moves continuously and has radial impact force; the long axis fulcrum is increased to reduce the disturbance of the long axis movement and protect the long axis; the chuck interface design is adopted to facilitate disassembly and replacement; the flexible design in the axial direction is adopted, and the shock absorption and vibration reduction effect is obvious; the overall structure is compact, material saving, and industrial aesthetic performance is strong; this support device is of universal design, strong interchangeability, low price, and easy to make. In addition, it can not only be used in the field of mixers, but also in related tests such as desulfurization and denitrification, pipelines, wind tunnels, etc., and can be adapted to various assembly scenes with rotating shafts.
[0037] It should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0038] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure.
