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 field of mixing equipment, the overall matching installation of large cylinders and shaft-type workpieces (mixing shafts) has always been a difficult point in the assembly process. The reason is that such cylinders and shaft-type workpieces are too long and too heavy. The assembly must build a special mounting bracket and use large lifting equipment to assist in the assembly. However, how to avoid collision and scratching between the shaft-type workpiece and the inner wall of the large cylinder workpiece during the assembly process is still a problem.

[0026] As shown in Figure 1 to Figure 7 As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a large-scale stirring shaft installation protection device, which includes a fixing frame 300 and a plurality of protection member 500 groups, wherein the fixing frame 300 is used to detachably connect the cylinder body 200 and make the cylinder body 200 in a vertical state; the plurality of protection member 500 groups are arranged at intervals in the axial direction of the shaft workpiece 400, and the protection member 500 group includes a plurality of protection members 500, and the plurality of protection members 500 of the same protection member 500 group are arranged at intervals in the circumferential direction of the shaft workpiece 400, and the protection member 500 and the shaft workpiece 400 are detachably connected; wherein, one end of the protection member 500 away from the shaft workpiece 400 protrudes from the outer wall of the shaft workpiece 400, and one end of the protection member 500 away from the shaft workpiece 400 is at least partially set as an elastic structure.

[0027] In these embodiments, the present application is a solution to the problem that collisions and scrapes are easily caused during the assembly process between the large cylinder 200 and the shaft workpiece 400. This large stirring shaft installation protection device is designed with several key components to realize its functions.

[0028] The fixing frame 300 is a structure that can be temporarily installed on the cylinder 200 , and its main function is to keep the cylinder 200 in a vertical position to facilitate the insertion and positioning of the shaft workpiece 400 .

[0029] The protective member 500 group is a group consisting of a plurality of protective members 500, which are distributed along the length direction of the shaft workpiece 400 and are also distributed at intervals in the circumferential direction of the shaft workpiece 400. The protective members 500 are connected to the shaft workpiece 400 in a detachable manner, which means that the protective members 500 can be easily removed after use.

[0030] The side of the protective member 500 away from the shaft workpiece 400 has a protruding portion, and this portion is at least partially made of elastic material. Such a design can provide a buffering effect when the protective member 500 contacts the inner wall of the cylinder 200, reduce the possibility of direct impact, and thus protect the workpiece surface from damage.

[0031] Of course, in other embodiments, the entire protective member 500 is configured as an elastic structure. Alternatively, one end of the protective member 500 abuts against the inner wall of the cylinder 200, and the other end is connected to the shaft workpiece 400, and the middle part of the protective member 500 is configured as an elastic structure, which can also achieve the above effect.

[0032] Obviously, the design of such a protective device not only helps to protect the workpiece surface from damage, but also improves the safety and efficiency of the assembly process. By using such a protective device, damage caused by bumps or scratches can be significantly reduced, thereby reducing maintenance costs and improving product quality. In addition, since the protective members 500 are detachable, they can be adjusted or replaced according to different workpiece sizes, increasing the flexibility and applicability of the device.

[0033] In some embodiments, the protective member 500 includes a balloon 530 , one end of the balloon 530 is connected to the shaft workpiece 400 , and the other end of the balloon 530 protrudes from the outer wall of the shaft workpiece 400 .

[0034] In these embodiments, the protective member 500 is designed to include a balloon 530. As a flexible structure, the balloon 530 can provide a better buffering effect when the shaft workpiece 400 contacts the inner wall of the cylinder 200. The deformability of the balloon 530 enables it to change its shape when squeezed, thereby reducing the damage caused by hard collision.

[0035] Furthermore, the use of the balloon 530 can enable the protective member 500 to automatically adjust its shape and size between the inner walls of the cylinder 200 of different diameters to adapt to different working environments, thereby increasing the versatility and adaptability of the device. At the same time, the surface of the balloon 530 is usually smooth, which helps to reduce the friction between the inner wall of the cylinder 200 and the shaft workpiece 400 during insertion, further protecting the workpiece surface from scratches.

[0036] For example, if the balloon 530 is inflated with air or liquid, it can also be used as a pressure sensing device. When the balloon 530 is over-squeezed, the pressure change can be used to prompt the operator to adjust the operation in time to avoid damage caused by squeezing too tightly. Alternatively, the transparent or translucent balloon 530 can also be used as a visual prompt tool to judge the situation in the assembly process by observing the state of the balloon 530 (such as the degree of deformation), helping the operator to better control the assembly process.

[0037] The balloon 530 can be made of a variety of materials, such as rubber, plastic, etc. The most suitable material can be selected according to specific working conditions to achieve the best protective effect. By using the balloon 530 as a part of the protective member 500, the device can not only more effectively prevent bumps and scratches, but also provide more functions, such as self-adaptation, friction reduction, and pressure sensing, thereby further optimizing the assembly process and improving assembly quality and efficiency.

[0038] Exemplarily, in the expanded state, the balloon 530 is spherical. Of course, in other embodiments, in the expanded state, the balloon 530 may also be elliptical, cylindrical, etc.

[0039] In some embodiments, the protective member 500 further includes an abutment portion 510 , which is connected to an end of the balloon 530 facing away from the shaft-like workpiece 400 , and the abutment portion 510 is used to abut against the inner wall of the cylinder 200 .

[0040] In these embodiments, the protective member 500 includes not only the balloon 530 but also an abutment portion 510. This design further improves the function and performance of the protective device.

[0041] The abutment portion 510 contacts the inner wall of the cylinder 200, providing an additional support point, making the shaft workpiece 400 more stable during the insertion process, reducing the bumps and scratches caused by shaking or offset. In addition, the abutment portion 510 can evenly distribute the pressure from the inner wall of the cylinder 200, preventing the balloon 530 from being deformed or damaged due to excessive local pressure, thereby protecting the balloon 530 and the shaft workpiece 400 inside it. In other words, the expansion and contraction of the balloon 530 can drive the abutment portion 510 away from or close to the inner wall of the cylinder 200, and can adjust the extrusion force of the abutment portion 510 on the inner wall of the cylinder 200. In particular, after the shaft workpiece 400 is installed, the abutment portion 510 can be driven away from the inner wall of the cylinder 200 by contracting the balloon 530, thereby facilitating the removal of the protective member 500.

[0042] The presence of the abutment 510 makes the position of the protective member 500 more fixed, and even in a complex assembly environment, it can ensure that the protective member 500 will not be displaced or fail due to external forces. By contacting the inner wall of the cylinder 200, the abutment 510 can effectively limit the radial movement of the shaft workpiece 400, thereby ensuring that the shaft workpiece 400 always maintains correct alignment during the assembly process, thereby improving assembly accuracy.

[0043] Furthermore, each protective member 500 group includes a plurality of protective members 500, and the abutment portion 510 can form a plurality of contact points, which are distributed around the entire shaft workpiece 400, so that the position of the shaft workpiece 400 in the cylinder 200 is more stable. In some cases, the abutment portion 510 can serve as the first line of defense, bearing the pressure from the inner wall of the cylinder 200, and protecting the balloon 530 from being over-compressed or damaged.

[0044] Exemplarily, the abutment portion 510 is made of a hard material. Optionally, the abutment portion 510 is spherical, rectangular, or the like.

[0045] In some embodiments, the abutting portion 510 is a non-metallic component.

[0046] In these embodiments, the abutment portion 510 is designed as a non-metallic component. Non-metallic materials are usually lighter than metals. Using non-metallic materials can reduce the weight of the abutment portion 510, thereby reducing the total weight of the entire protective device. This is particularly important for occasions that require frequent disassembly and assembly, and can reduce the labor intensity of operators.

[0047] Non-metallic materials often have good corrosion resistance, especially in a humid or chemical-rich environment, non-metallic parts are not easy to rust or corrode, which prolongs the service life of the protective device. In addition, non-metallic materials usually have a lower friction coefficient, which can reduce wear when contacting the inner wall of the cylinder 200, protecting the cylinder 200 and other workpiece surfaces from damage.

[0048] For example, non-metallic materials such as plastic, rubber, etc. are usually easier to process and shape, and the abutment portion 510 of different shapes and sizes can be customized according to specific needs to meet diverse assembly requirements.

[0049] In some embodiments, the abutment portion 510 is configured as a self-lubricating component.

[0050] In these embodiments, the abutment portion 510 is designed as a self-lubricating component. The self-lubricating component can reduce the friction with the inner wall of the cylinder 200 without additional lubricant, thereby reducing friction, making the shaft workpiece 400 smoother during insertion and reducing damage to the workpiece surface.

[0051] The self-lubricating component reduces the dependence on lubricants, avoids the increased wear after the lubricant dries up or fails, and thus prolongs the service life of the protective device. The self-lubricating property enables the abutment portion 510 to maintain stable performance in various working environments, without the need for frequent addition of lubricants, thereby improving the reliability and maintenance cycle of the device. The self-lubricating component can work normally in a variety of harsh environments such as high temperature, low temperature, high humidity, and dust, without worrying about lubricant volatilization or contamination.

[0052] For example, the abutment portion 510 is configured as a nylon block. Of course, in other embodiments, the abutment portion 510 may also be configured as a thermoplastic elastomer, an ultra-high molecular weight polyethylene body, and the like.

[0053] In some embodiments, the end of the abutting portion 510 away from the shaft workpiece 400 is a pointed end.

[0054] In these embodiments, the tip can more easily find and contact the exact position of the inner wall of the barrel 200, which helps to accurately align the shaft workpiece 400 and the barrel 200. The tip reduces the actual contact area with the inner wall of the barrel 200, which means that the friction generated during contact is smaller, thereby reducing the wear on the inner wall of the barrel 200. The tip design can concentrate the pressure at one point, so that even if there is a slight deviation during the assembly process, it can be adjusted through the guiding effect of the tip.

[0055] Since the contact area of ​​the tip is small, deformation caused by extrusion can be reduced, thereby protecting the inner surface of the cylinder 200 from damage.

[0056] Furthermore, the presence of the tip makes it more intuitive to detect whether the assembly process is correctly aligned, and the operator can judge whether adjustment is needed by observing the position of the tip. During the insertion or extraction of the shaft workpiece 400, the tip can reduce resistance and make the operation smoother.

[0057] Exemplary, the tip is set to a spherical tip. Of course, in other embodiments, the tip also can be set to a trapezoidal tip or the like.

[0058] In some embodiments, the protective member 500 also includes a shell 520 and a spring 560, the shell 520 is connected to the shaft workpiece 400, and the end of the shell 520 facing away from the shaft workpiece 400 has a guide hole; wherein the balloon 530 is located in the shell 520, the abutment portion 510 is slidably arranged in the guide hole at one end close to the shaft workpiece 400, and the end face of the abutment portion 510 at one end located in the shell 520 is connected to the end of the balloon 530 facing away from the shaft workpiece 400; one end of the spring 560 is connected to the shell 520, and the other end of the spring 560 is connected to the abutment portion 510.

[0059] In these embodiments, the housing 520 is connected to the shaft workpiece 400 to form a complete protection unit. The use of the housing 520 makes the protection member 500 a more integrated whole, which is convenient for installation and removal. Among them, the housing 520 has a guide hole at one end away from the shaft workpiece 400, and the guide hole is used to guide the abutment portion 510 to slide through, thereby achieving a distance from or proximity to the inner wall of the cylinder 200, ensuring that the abutment portion 510 can move along a predetermined path during the movement to avoid deviation from the track.

[0060] The balloon 530 is located inside the shell 520 and is protected by the shell 520, thereby avoiding direct damage to the balloon 530 by the external environment and improving the service life of the balloon 530. The end of the abutment portion 510 close to the shaft workpiece 400 slides through the guide hole. This design allows the abutment portion 510 to slide freely within a certain range as needed, adapt to changes in different positions, and maintain good contact with the inner wall of the cylinder 200.

[0061] One end of the abutment portion 510 located in the housing 520 is connected to the end of the balloon 530 away from the shaft workpiece 400. This connection method ensures that the abutment portion 510 can still maintain effective contact with the balloon 530 when sliding, and together play a buffering and protective role. The design of the housing 520 increases the stability of the entire protective device, making the position of the shaft workpiece 400 more secure during the assembly process.

[0062] It should be noted that the shell 520 protects the balloon 530 and prevents the balloon 530 from being directly hit or worn by external objects during the assembly process.

[0063] The spring 560 is used to drive the abutment portion 510 to return to its original position after the balloon 530 is deflated, thereby moving the abutment portion 510 away from the inner wall of the cylinder 200 .

[0064] Exemplarily, the housing 520 is a metal housing 520. Of course, in other embodiments, the housing 520 may also be a plastic housing 520.

[0065] In some embodiments, the protective member 500 also includes a mounting seat 540 and a plurality of tightening portions 550, the mounting seat 540 having a first connecting end and a second connecting end relative to each other, the second connecting end being connected to the shell 520; wherein the first connecting end is located between adjacent stirring blades 410 on the shaft workpiece 400; the plurality of tightening portions 550 are distributed on both sides of the first connecting end, one end of the tightening portion 550 is threadedly connected to the first connecting end, and the other end of the tightening portion 550 is abutted against the stirring blade 410 on the corresponding side.

[0066] In these embodiments, the protective member 500 not only includes the aforementioned housing 520, balloon 530 and abutment portion 510, but also further includes a mounting seat 540 and a plurality of tightening portions 550. This design allows the protective member 500 to be easily assembled and disassembled on the shaft workpiece 400.

[0067] The mounting base 540 has a first connecting end and a second connecting end opposite to each other, wherein the second connecting end is connected to the housing 520. This means that the mounting base 540 is responsible for fixing the housing 520 on the shaft workpiece 400. The first connecting end is located between adjacent stirring blades 410 on the shaft workpiece 400, so that the space can be fully utilized to ensure that the mounting base 540 does not interfere with the operation of the stirring blades 410.

[0068] Multiple tightening parts 550 are distributed on both sides of the first connection end to ensure that the mounting base 540 is fixed from multiple directions. One end of the tightening part 550 is connected to the first connection end by a thread, so that the position and tightening degree of the tightening part 550 can be easily adjusted. The other end of the tightening part 550 abuts against the corresponding stirring blade 410, and the mounting base 540 is further fixed by tightening the blade.

[0069] Obviously, the mounting seat 540 can be firmly fixed on the shaft workpiece 400 and is not easy to loosen through the abutment between the pressing part 550 and the stirring blade 410. Multiple pressing parts 550 can be adjusted according to actual conditions, suitable for stirring blades 410 with different spacings and numbers, and enhance the adaptability of the protective device.

[0070] Furthermore, the tightening portion 550 and the mounting seat 540 are connected by threads, which can be easily adjusted to meet different installation requirements and is also convenient for disassembly and maintenance.

[0071] Furthermore, the design of the mounting seat 540 and the tightening portion 550 makes the installation and removal of the protective member 500 easier and faster, thereby reducing the difficulty of operation.

[0072] Exemplarily, the tightening portion 550 is a tightening bolt. Of course, in other embodiments, the tightening portion 550 is a stud or the like.

[0073] For example, two pressing parts 550 are respectively arranged on both sides of the first connection end. Of course, the number of pressing parts 550 respectively arranged on both sides of the first connection end is three, four, five, six, etc.

[0074] In some embodiments, the abutment portion 510 has a large diameter end and a small diameter end, the small diameter end is passed through the guide hole, and the large diameter end is located in the shell 520 and abuts against the balloon 530; wherein the outer diameter of the large diameter end is larger than the aperture of the guide hole.

[0075] In these embodiments, the abutment portion 510 is designed to have a large diameter end and a small diameter end, and this design further enhances the functionality and stability of the protective device. The large diameter end is located in the housing 520 and abuts against the balloon 530 (assuming that it refers to the balloon 530 here), playing a role in supporting the balloon 530. The small diameter end is penetrated through the guide hole on the housing 520, so that the abutment portion 510 can slide along a predetermined path under the guidance of the guide hole. The aperture of the guide hole is smaller than the outer diameter of the large diameter end, so that the abutment portion 510 can only pass through the guide hole through the small diameter end, while the large diameter end is restricted in the housing 520 to prevent the abutment portion 510 from completely detaching from the housing 520.

[0076] That is to say, the outer diameter of the large diameter end is larger than the aperture of the guide hole, so that the abutment part 510 can only pass through the guide hole through the small diameter end, thereby limiting the range of motion of the abutment part 510 and ensuring that it will not separate from the housing 520 during the sliding process. The large diameter end abuts against the balloon 530, which can provide a stable support force, so that the balloon 530 can still maintain its shape when under pressure, and play a good buffering role. The small diameter end passes through the guide hole, so that the abutment part 510 can slide under the guidance of the guide hole, ensuring that the abutment part 510 will not deviate from the predetermined path during the movement, thereby improving the reliability and stability of the device. The large diameter end is located in the housing 520 and abuts against the balloon 530, protecting the balloon 530 from direct damage by the external environment. At the same time, the large diameter end can transmit pressure to the balloon 530, causing it to expand or deform to adapt to different contact surfaces.

[0077] In some embodiments, the protective element 500 further includes an inflation and deflation unit, and each balloon 530 is respectively connected to the inflation and deflation unit, and the inflation and deflation unit is used to adjust the air pressure of the corresponding balloon 530 .

[0078] In these embodiments, the protective member 500 further includes an inflation and deflation portion, and each balloon 530 is connected to an inflation and deflation portion via a trachea, and is used to adjust the air pressure of the corresponding balloon 530 through inflation and deflation.

[0079] Each balloon 530 is connected to an air filling and discharging unit, which can independently adjust the air pressure in the balloon 530. The air filling and discharging unit can be a manual or automatic valve system for controlling the inflow and outflow of gas in the balloon 530. Since each balloon 530 has a separate air filling and discharging unit, the air pressure of each balloon 530 can be independently adjusted according to actual conditions to adapt to different assembly conditions and workpiece surface conditions.

[0080] The design of the inflation and deflation part enables the air pressure of each balloon 530 to be adjusted independently, so that the hardness of the balloon 530 at different positions can be adjusted according to actual needs to meet different assembly requirements.

[0081] Obviously, the air pressure in the balloon 530 can be adjusted in real time through the inflation and deflation part to ensure that the balloon 530 provides appropriate cushioning force when contacting the inner wall of the cylinder 200, which is neither too soft nor too hard, thereby reducing the risk of bumps and scratches.

[0082] Furthermore, during the assembly process, by adjusting the volume of the corresponding balloon 530 and thereby controlling the extended length of the abutment portion 510 , the insertion direction of the shaft workpiece 400 can be controlled and adjusted.

[0083] In some embodiments, the present application further provides a large agitator shaft installation protection method, using a large agitator shaft installation protection device as described in any one of the above embodiments, and the large agitator shaft installation protection method comprises the following steps: The cylinder 200 is detachably mounted on the fixing frame 300 so that the cylinder 200 is in a vertical state; The shaft workpiece 400 is hoisted by using the lifting device 100 so that the shaft workpiece 400 is in a vertical state; A plurality of protective members 500 are arranged in an axial direction of the shaft workpiece 400 at intervals, and a plurality of protective members 500 of the same protective member 500 group are arranged in a circumferential direction of the shaft workpiece 400 at intervals, and the protective member 500 and the shaft workpiece 400 are detachably connected, and one end of the protective member 500 away from the shaft workpiece 400 protrudes from the outer wall of the shaft workpiece 400; The position of the shaft workpiece 400 is adjusted by using the lifting device 100 , so that the shaft workpiece 400 is aligned with the cylinder 200 and then lowered and enters the cylinder 200 until the shaft workpiece 400 moves into position.
