The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0022] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] In the related art, the blade installation part of the large stirring shaft has a barrel length of more than 15,000 mm, a diameter of more than 2,500 mm, and nearly 500 blades. After the blades are installed, the overall straightness of the stirring shaft is less than 0.5 mm, the roundness is less than 0.5 mm, and the total dynamic balance is ≤5,000,000 g.mm. The blades are connected to the main shaft of the stirring shaft with bolts, which need to be installed manually, and the required precision is difficult to achieve. After nearly 500 blades are installed, if the precision after assembly does not meet the requirements, it will be labor-intensive and time-consuming to adjust due to space limitations.

[0026] As shown in Figure 1 to Figure 6 As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a blade installation auxiliary tooling for a large stirring shaft, and the blade installation auxiliary tooling for a large stirring shaft includes a support assembly 1 and a reference assembly, wherein the support assembly 1 is detachably rotatably connected to at least one end of the stirring shaft 6, so that the stirring shaft 6 can rotate around the axis of the stirring shaft 6; the reference assembly includes a reference part, and the surface of the reference part has a reference line, which extends along the axis of the stirring shaft 6, and the distance between the reference line and the axis of the stirring shaft 6 is not less than the maximum outer diameter of the stirring shaft 6.

[0027] In these embodiments, the design of the auxiliary tooling for installing the blades of the large stirring shaft is very ingenious. By introducing the support component 1 and the reference component, the accuracy and low efficiency problems existing in the traditional installation process are effectively solved.

[0028] The detachable rotating connection design between the support assembly 1 and one end of the stirring shaft 6 ensures that the stirring shaft 6 can rotate freely during installation. This feature is essential for evenly distributing the blades 9 and checking the accuracy after installation. Since it is detachable, the blades 9 can be easily removed after installation without affecting subsequent use.

[0029] It should be noted that the reference assembly provides an accurate position reference for the installation of the blade 9 by setting the reference line. This not only helps to ensure the installation accuracy of each blade 9, but also effectively controls the straightness and roundness of the entire stirring shaft 6 to meet strict tolerance requirements. Among them, the reference line is kept at a certain distance from the axis of the stirring shaft 6 (not less than the maximum outer diameter), which means that even on a larger stirring shaft 6, the reference line can be ensured to be clearly visible. The operator measures the distance between the blade 9 rotated to the reference line and the reference line to obtain the installation accuracy, which is easy for the operator to perform calibration work.

[0030] For example, the blade 9 extends along the axis of the stirring shaft 6, and when the blade 9 and the reference line are coplanar, the distance S between the blade 9 and the reference line can be measured to determine whether the distance meets the set standard, thereby serving as a basis for whether to install in place or adjust the position of the blade 9.

[0031] Furthermore, the reference part can be a hard part or a soft part, as long as the reference line on the reference part is parallel to the axis of the stirring shaft 6 and remains unchanged during the measurement process. It should be noted that when the reference part is a soft part, the soft part can be set to be in a taut and non-deformable state.

[0032] Furthermore, the reference line should be located on the surface of the reference part and be easy to observe and operate. For example, the reference part is cylindrical, and the reference line is set at the generatrix of the reference part closest to the axis of the stirring shaft 6. Of course, it can also be set to other generatrixes on the reference part.

[0033] Obviously, with the help of the above design, the operator can complete the installation of the blade 9 more efficiently, reducing the time wasted due to repeated adjustments. In addition, by improving the installation accuracy, the performance of the final product can be significantly improved, such as reducing vibration during operation, extending the service life, etc. Of course, this installation method reduces the manpower burden, which is particularly important when dealing with large equipment. In short, this blade installation auxiliary tooling for large stirring shafts not only solves many problems existing in traditional methods through innovative design, but also greatly improves work efficiency and product quality, which is of great significance to the production and manufacturing of related industries.

[0034] In some embodiments, the support assembly 1 includes a pair of support members 5, the support members 5 have mounting holes 2, the stirring shaft 6 is located between the pair of support members 5, and the ends of the stirring shaft 6 are inserted into the mounting holes 2 of the support members 5 on the corresponding sides, and the ends of the stirring shaft 6 and the corresponding mounting holes 2 are clearance-fitted.

[0035] In these embodiments, the support members 5 appear in pairs, respectively located at the two ends of the stirring shaft 6, to ensure that the stirring shaft 6 can be stably supported during the installation process. Each support member 5 has a mounting hole 2 for accommodating the end of the stirring shaft 6. The size and shape of these mounting holes 2 are precisely designed to ensure clearance fit with the end of the stirring shaft 6. Obviously, a clearance fit is adopted between the end of the stirring shaft 6 and the mounting hole 2, that is, the diameter of the mounting hole 2 is slightly larger than the diameter of the end of the stirring shaft 6, to ensure that the stirring shaft 6 can rotate freely in the mounting hole 2, but will not produce excessive shaking or looseness, so as to ensure the matching accuracy between the reference line and the axis of the stirring shaft 6.

[0036] Obviously, the design of clearance fit allows the stirring shaft 6 to maintain a stable rotation state during installation, avoiding installation errors caused by shaking or loosening, and facilitating the operator to more accurately control the position of the blade 9, ensuring that each blade 9 can be installed at a predetermined position and angle. In addition, the design of the support 5 allows the stirring shaft 6 to be easily placed and fixed, and the operator can complete the initial fixation without additional tools or complex devices. The free rotation feature makes the installation of the blade 9 more flexible and convenient for adjustment and inspection.

[0037] Furthermore, the clearance fit design reduces the need for complex fixing of the stirring shaft 6, speeding up the installation speed. The operator can complete the installation and calibration of the blade 9 more quickly, reducing the time for repeated adjustments and improving the overall work efficiency.

[0038] For example, the length of the large stirring shaft 6 exceeds 15000 mm and the diameter exceeds 2500 mm, and nearly 500 blades 9 need to be installed. Using the design of this support assembly 1, the specific steps are as follows: A pair of support members 5 are placed at both ends of the stirring shaft 6 respectively, ensuring that the mounting holes 2 on the support members 5 are aligned with the ends of the stirring shaft 6 .

[0039] Insert the end of the stirring shaft 6 into the mounting hole 2 of the support member 5 to ensure that the stirring shaft 6 can rotate freely in the mounting hole 2 .

[0040] The support 5 is fixed in place using a simple fixing device such as a clamp, ensuring that the stirring shaft 6 does not slide or tilt during installation.

[0041] The operator can evenly distribute the blades 9 around the stirring shaft 6 and use the reference line provided by the reference assembly for accurate alignment. During installation, the position and angle of the blades 9 can be checked by rotating the stirring shaft 6 to ensure that each blade 9 is installed correctly.

[0042] After installation, check the straightness and roundness of the agitator shaft 6 again to ensure that it meets the design requirements. Through this design, the accuracy and efficiency of the installation of the large agitator shaft 6 blades 9 can be significantly improved, reducing time and labor costs, while improving the stability and reliability of the equipment.

[0043] In some embodiments, the reference member is a wire 8, one end of the wire 8 is connected to one of the support members 5, the other end of the wire 8 is connected to the other support member 5, and the wire 8 is in a taut state.

[0044] In these embodiments, this design further optimizes the blade installation auxiliary tooling of the large stirring shaft, bringing many improvements and benefits. The wire 8 is used as the reference piece. The wire 8 is slender and has good straightness, and can provide a very accurate reference line. The material of the wire 8 can be selected from high-strength materials, such as steel wire or nylon wire, to ensure that it is not easy to break during use.

[0045] One end of the wire 8 is fixed to one support 5, and the other end is fixed to another support 5, ensuring that the wire 8 is tightened along the axis direction of the stirring shaft 6. The fixing point can select a suitable fixing device, such as a screw, a clamp or a special fixing seat, to ensure the stability and straightness of the wire 8. The tightened wire 8 can provide a clear and stable reference line to help the operator to accurately align the blade 9 when installing it. The tightened state can reduce the shaking and shaking of the wire 8 and ensure the stability of the reference line.

[0046] Obviously, the taut wire 8 provides a clear and stable reference line, and the operator can intuitively see the position of the reference line to ensure that each blade 9 can be accurately aligned. The accurate reference line helps to reduce the installation deviation of the blade 9 caused by visual error or measurement error, and improves the overall installation accuracy. Furthermore, using the wire 8 as a reference line can significantly increase the speed of blade 9 installation, reduce the time of repeated adjustments, and improve work efficiency.

[0047] In some embodiments, the reference assembly further includes a tension adjusting member 3 , at least one of a pair of support members 5 is provided with a tension adjusting member 3 , the tension adjusting member 3 is connected to a corresponding end of the wire 8 , and the tension adjusting member 3 is used to adjust the tightness of the wire 8 .

[0048] In these embodiments, the reference assembly not only includes the wire 8 as the reference member, but also adds a tension adjustment member 3. This design further optimizes the blade installation auxiliary tooling for large stirring shafts, bringing more functions and benefits.

[0049] The tension adjusting member 3 is mounted on at least one of the pair of supporting members 5 and connected to the corresponding end of the thread 8. The tension adjusting member 3 is used to adjust the tightness of the thread 8 to ensure that the thread 8 is always in an ideal tension state. One end of the thread 8 is fixed to one supporting member 5, and the other end is fixed to the other supporting member 5 through the tension adjusting member 3. The tension adjusting member 3 can be a threaded adjusting rod, a spring clip or other similar device, and the tension of the thread 8 can be changed by turning a knob or manually adjusting.

[0050] Obviously, by adjusting the tightness of the thread 8 through the tension adjusting member 3, it is possible to ensure that the thread 8 is always kept in a taut state, providing an accurate reference line. An accurate reference line helps to reduce the installation error caused by the looseness of the thread 8 and improve the overall installation accuracy. In addition, the tension adjusting member 3 allows the operator to adjust the tightness of the thread 8 at any time according to the actual situation to ensure the stability of the reference line.

[0051] In some embodiments, a pair of support members 5 are each provided with a tensioning adjustment member 3, the tensioning adjustment member 3 includes a tensioning positioning sleeve 10 and a tensioning bolt 7, the support member 5 also has a positioning hole 11, the axis of the positioning hole 11 is arranged parallel to the axis of the mounting hole 2, the tensioning positioning sleeve 10 is inserted into the positioning hole 11, the tensioning positioning sleeve 10 and the positioning hole 11 are clearance fit or interference fit, and the tensioning bolt 7 has an axial through hole, the tensioning bolt 7 and the inner hole of the tensioning positioning sleeve 10 are threadedly connected at one end away from the stirring shaft 6, and one end of the wire 8 is sequentially inserted into the inner hole of the tensioning positioning sleeve 10, the axial through hole and connected to the support member 5 on the corresponding side.

[0052] In these embodiments, a pair of support members 5 are each provided with a tension adjustment member 3. This design further optimizes the blade installation auxiliary tooling for a large stirring shaft and provides higher precision and flexibility.

[0053] A tension adjusting member 3 is installed on each support member 5 to ensure that the tightness of the thread 8 can be adjusted from both sides. Among them, the tensioning sleeve 10 of the tension adjusting member 3 is installed in the positioning hole 11 of the support member 5 to guide and fix the thread 8. The tensioning bolt 7 has an axial through hole, which is threadedly connected to the end of the inner hole of the tensioning sleeve 10 away from the stirring shaft 6 to adjust the tightness of the thread 8. A positioning hole 11 is provided on the support member 5, and the axis of the positioning hole 11 is arranged parallel to the axis of the mounting hole 2. The tensioning sleeve 10 is inserted into the positioning hole 11, and a clearance fit or an interference fit can be adopted to ensure the stability and flexibility of the tensioning sleeve 10. One end of the thread 8 is successively inserted into the inner hole of the tensioning sleeve 10 and the axial through hole of the tensioning bolt 7, and then connected to the support member 5 on the corresponding side.

[0054] This connection method ensures that the wire 8 can be kept in a taut state under the adjustment of the tension bolt 7. Through the tension adjustment members 3 on both sides, the tightness of the wire 8 can be adjusted more accurately, ensuring that the wire 8 is always kept in a taut state, providing an accurate reference line. The accurate reference line helps to reduce the installation error caused by the loosening of the wire 8 and improve the overall installation accuracy. The tension adjustment members 3 on both sides allow the operator to adjust the tightness of the wire 8 from either side to ensure the stability of the reference line.

[0055] It is easy to understand that the tightness of the thread 8 can be adjusted by rotating the tension bolt 7. For example, the thread 8 can be tightened by rotating the tension bolt 7 forward, and the thread 8 can be loosened by rotating the tension bolt 7 reversely.

[0056] In some embodiments, the tensioning and positioning sleeve 10 and the corresponding supporting member 5 are detachably connected.

[0057] Exemplarily, the tensioning and positioning sleeve 10 and the corresponding support member 5 are connected by fixing bolts. Of course, in other embodiments, the tensioning and positioning sleeve 10 and the corresponding support member 5 are connected by positioning pins.

[0058] In some embodiments, the wire 8 and the inner hole of the tensioning and positioning sleeve 10 are clearance-matched.

[0059] In these embodiments, the wire 8 and the inner hole of the tensioning and positioning sleeve 10 are clearance-fitted, and this design further optimizes the blade installation auxiliary tooling of the large stirring shaft, providing higher precision and flexibility. The clearance fit between the wire 8 and the inner hole of the tensioning and positioning sleeve 10, and the existence of a certain gap between the wire 8 and the inner hole of the tensioning and positioning sleeve 10, ensure that the wire 8 can slide freely in the inner hole without causing excessive shaking or looseness. This clearance fit design makes the wire 8 smoother when adjusting the tightness, reduces friction resistance, and ensures the relative position accuracy between the reference line and the axis of the stirring shaft 6.

[0060] It should be noted that the above arrangement facilitates the installation of the tensioning and positioning sleeve 10 in the positioning hole 11 of the support member 5 , and the two are also clearance-fitted for guiding and fixing the wire 8 .

[0061] In some embodiments, there are multiple reference components, and the multiple reference components are arranged at intervals along the circumference of the stirring shaft 6.

[0062] In these embodiments, there are multiple reference components, and the multiple reference components are arranged at intervals along the circumference of the stirring shaft 6. This design further optimizes the blade installation auxiliary tooling of the large stirring shaft and provides higher precision and flexibility.

[0063] There are multiple reference components, each of which includes a wire 8, a tensioning sleeve 10 and a tensioning bolt 7. Multiple reference components are arranged at intervals along the circumference of the stirring shaft 6 to ensure clear reference lines at different positions.

[0064] Obviously, multiple reference components are arranged at intervals along the circumference of the stirring shaft 6, providing multi-directional reference lines to ensure that each blade 9 can be accurately aligned in different directions. Multi-directional reference lines help reduce installation errors caused by single-line references and improve overall installation accuracy. Multiple reference components ensure that there are clear reference lines throughout the circumference, and operators can easily perform alignment and adjustment.

[0065] Exemplarily, in this embodiment, the number of the reference components is two. Of course, in other embodiments, the number of the reference components is three, four, five, six, etc.

[0066] In some embodiments, the end of the wire 8 is wound around the fastening bolt 4 , the fastening bolt 4 and the corresponding support member 5 are threadedly connected, and the portion of the wire 8 wound around the fastening bolt 4 is clamped between the fastening bolt 4 and the support member 5 .

[0067] Obviously, the threaded connection design of the fastening bolt 4 and the support member 5 allows the wire 8 to be quickly fixed and is easy to operate.

[0068] In some embodiments, the thread of the tensioning bolt 7 is a fine pitch thread.

[0069] In these embodiments, by setting the tensioning bolt 7 as a fine-pitch thread, self-locking of the tensioning bolt 7 can be achieved, that is, thread slippage can be effectively prevented, thereby ensuring that the adjusted wire 8 is tensioned and not loose.
