[0030] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments.
[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention is further described in detail below with reference to the accompanying drawings.
[0032] A double-support impeller adjustable transfer rack, such as Figures 1-10As shown, it includes a width adjustment bracket 1, an impeller shaft adjustment fixing block 2 and a side ear 3. The impeller shaft adjustment fixing block 2 is installed on the top of the width adjustment bracket 1, and the side ears 3 are installed on both sides of the width adjustment bracket 1. The width adjustment bracket 1 includes a left bracket 11, a right bracket 12, a first adjustment arm 4 and a second adjustment arm 5. The left bracket 11 is equipped with a symmetrically arranged first adjustment arm 4, and the right bracket 12 is equipped with a symmetrically arranged second adjustment arm 5. The left bracket 11 and the right bracket 12 are arranged opposite to each other. The length of the bottom cross beam of the right bracket 12 is greater than the length of the bottom cross beam of the left bracket 11. The second adjustment arm 5 is movably installed on the first adjustment arm 4. The width adjustment bracket 1 is composed of multiple C-shaped steels welded together, and the first adjustment arm 4 and the second adjustment arm 5 are arranged back to back oppositely. Due to the length of the bottom cross beam of the right bracket 12, the width adjustment bracket 1 is provided with a plurality of C-shaped steels welded together. The first adjustment arm 4 and the second adjustment arm 5 are arranged back to back oppositely. At the bottom crossbeam of the left bracket 11, its first adjusting arm 4 can be easily incorporated into the second adjusting arm 5 for back-to-back abutment. The components are highly versatile, easily mass-produced, and have low production costs, which can effectively improve delivery time. It allows users to easily adjust the distance between the two brackets according to the actual width of the impeller. Without complex tools or professional knowledge, adaptation can be quickly completed, thereby improving work efficiency. The gantry lifting rope is passed through the side ear 3 to be hoisted to the transfer vehicle for transportation. The protruding shafts on both sides of the impeller are firmly supported by the impeller shaft adjustment fixing block 2 to ensure stability during transportation. In the case of urgent delivery or mass production, the transfer frame can be quickly adjusted to adapt to different impellers without replacing the entire transfer equipment, thereby simplifying the transfer process, shortening preparation time, and improving overall work efficiency.
[0033] Symmetrically arranged side ears 3 are installed on both sides of the left bracket 11 and the right bracket 12. Impeller shaft adjustment fixing blocks 2 are installed on the top of the left bracket 11 and the top of the right bracket 12. The left bracket 11 as a whole and the right bracket 12 as a whole are isosceles trapezoidal, which effectively enhances the stability of the bracket. The first adjustment arm 4 is symmetrically installed at both ends of the bottom beam of the left bracket 11, and the second adjustment arm 5 is symmetrically installed at both ends of the bottom beam of the right bracket 12. The top beams of the left bracket 11 and the right bracket 12 are the same size. Because the bottom beam of the right bracket 12 is slightly longer, the inclination angle of the two waist beams of the right bracket 12 is greater than that of the left bracket 11, ensuring that the two An adjusting arm 4 can be perfectly incorporated into the space formed by the two second adjusting arms 5, which not only saves space but also improves the overall aesthetics and practicality of the transfer rack. The two first adjusting arms 4 and the corresponding waist beam corners are installed with matching reinforcements 6, which further enhance the connection strength between the adjusting arms and the waist beam corners and improve the stability and safety of the overall structure. The structure of the right bracket 12 and the second adjusting arm 5 is consistent with that of the left bracket 11. The side ear 3 openings on the two waist beams of the left bracket 11 and the side ear 3 openings on the two waist beams of the right bracket 12 are at the same height and the same horizontal line to ensure the stability of subsequent lifting.
[0034] The impeller shaft support fixing block includes a V-shaped support block 21 and a pressure plate 22. The pressure plate 22 is movably installed at the large open end of the V-shaped support block 21. V-shaped support blocks 21 are installed on the top of the left bracket 11 and the right bracket 12. The pressure plate 22 is connected to the V-shaped support block 21 by bolts to ensure that the impeller shaft is in the V-shaped support block 21 to prevent it from being displaced and falling out during transportation. The V-shaped support blocks 21 of the two brackets are relatively arranged, and auxiliary reinforcements 6 are installed on the sides to further enhance the overall stability and prevent it from being deformed or damaged when bearing the weight of the impeller shaft and transportation stress. The V-shaped support block 21 can adapt well to the circular or approximately circular cross-section of the impeller shaft to provide stable support. The design of its large open end facilitates the placement and positioning of the impeller shaft, and also helps to disperse the stress and vibration generated by the impeller shaft during transportation.
[0035] The first adjusting arm 4 and the second adjusting arm 5 are provided with matching through holes, and the second adjusting arm 5 is adjustably mounted on the first adjusting arm 4 by bolts. The through holes include round holes and oblong holes, which are arranged in a linear array. The distance between the two adjusting arms is adjusted according to the width of the impeller, and the bolts are tightened according to the relative through holes to complete the stability. The design of the oblong holes allows a certain amount of fault tolerance during the adjustment process, making it easier and more accurate to fine-tune the position of the adjusting arms, reducing the tediousness and inconvenience during installation, while the round holes provide a precise position for the final locking, ensuring that the impeller position after adjustment is accurate and the operation is stable and reliable. The ends of the two first adjusting arms 4 away from the left bracket 11 are connected by an auxiliary fixing beam. Because the first adjusting arm 4 is inserted between the second adjusting arm 5, in order to maintain stability, an auxiliary fixing beam is welded between the ends of the two first adjusting arms 4 for reinforcement, thereby enhancing the stability and reliability of the entire structure. The addition of the auxiliary fixing beam effectively disperses possible stress and deformation, and improves the overall rigidity and durability.
[0036] Working principle: The staff adjusts the transfer frame as a whole according to the width of the impeller, pulls the right bracket 12 to make the second adjustment arm 5 and the first adjustment arm 4 of the left bracket 11 slide back to back until they are in the appropriate position, and locks them through the relative oblong holes and round holes. The impeller shaft of the impeller is further placed in the V-shaped support block 21, and is stabilized by locking the pressure plate 22 to complete the loading of the impeller. It is further lifted into the transport vehicle through the gantry crane and connected to the side ear 3 to complete the subsequent transfer and transportation.
