Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, specifically relating to a rotor support frame with a turning function. Background Technology

[0002] Rotor supports are widely used for the inspection and maintenance of rotor components in the mechanical field. During inspection, the rotor is lifted out and placed horizontally on the rotor support. Most supports use wooden sleepers as linings that directly contact the rotor spindle. When the inspection time is long, to prevent the spindle from bending or when the rotor needs on-site inspection and maintenance, the rotor needs to be manually rotated. At this time, the spindle part rubs hard against the sleepers. Due to the weight of the rotor, the sleepers are prone to breakage and shaking, causing wear to the spindle and posing certain safety risks.

[0003] Chinese patent document CN207691562U provides a tooling structure for integrating a single-bearing motor support and turning gear, solving the problem that a separate design of the single-bearing motor support and turning gear cannot achieve the integrated function of rotor fixed support and turning gear. However, this patent is only applicable to single-bearing motors and cannot be applied to different types of rotors, requiring different types of rotor support frames, resulting in idle waste.

[0008] Preferably, a bushing is fitted around the outside of the roller shaft, and the roller is connected to the bushing-fitted roller shaft via a bearing. A gap is left between the two rollers to support the rotor main shaft. The distance between the two rollers is adjustable.

By selecting different base bolt positioning holes, the base and the roller seat can be connected, and the distance between the two roller seats can be adjusted to achieve the purpose of being suitable for different models of rotors.

[0010] Preferably, the roller seat is connected and fixed to the base by bolts and washers.

[0011] Preferably, the base has a trapezoidal structure to stably support the rotor.

[0012] Preferably, the roller surface has a rubber coating, which is in direct contact with the rotor spindle to buffer the impact force of the rotor falling and increase the friction force during the turning process, thereby preventing rotor damage.

[0013] Preferably, the bearing is provided with end caps at both ends, which are fixed to the rollers to prevent foreign objects from entering the bearing and to keep the bearing rolling smoothly.

Detailed Implementation

[0018] This utility model provides a rotor support frame with a turning function, including a chassis 16 and a set (two) of support components mounted on the chassis 16, such as... Figure 1As shown, the bearings of rotor 17 are mounted on two support assemblies. The distance between the two support assemblies is adjustable to accommodate different rotor models. The chassis 16 has multiple chassis bolt positioning holes 14, and the support assemblies have support assembly bolt holes 13 that mate with the chassis bolt positioning holes 14. The support assemblies and chassis 16 are fixedly connected via the chassis bolt positioning holes 14, the support assembly bolt holes 13, and fixing bolts. By selecting the matching chassis bolt positioning holes 14 according to the distance between the two support assemblies, the distance between the support assemblies is adjusted to achieve centering of the rotor's center of gravity, thus accommodating different rotor models.

[0019] The support assembly includes a base 1, two roller seats 6 mounted on the base 1, and roller shafts 5 mounted on the roller seats 6. The roller shafts 5 are mounted to both ends of the roller seats 6 by positioning bolts 12. A bushing 4 is fitted over the outside of the roller shaft 5. Rollers 2 are connected to the roller shaft 5 with the bushing 4 via bearings 7. A gap is left between the two rollers 2 to support the main shaft of the rotor 17. The distance between the two rollers 2 is adjustable. Several base bolt positioning holes 15 are provided on the upper crossbeam of the base 1, corresponding to the bolt holes on the roller seats 6. The roller seats 6 and the base 1 are fixedly connected by the base bolt positioning holes 15, the bolt holes on the roller seats 6, and the fixing bolts. By selecting appropriate base bolt positioning holes 15 according to the bearing diameter and adjusting the distance between the two roller seats 6, the assembly can be adapted to different models of rotors 17.

[0020] The two ends of the main shaft of the rotor 17 are placed between the two rollers 2 of the two sets of support components to achieve the support function; the rollers 2 rotate with the rotor 17 to achieve the turning function.

[0021] The bearing 7 can significantly reduce stress during the turning process and reduce damage to the rotor 17 blades.

[0022] Specifically, the roller seat 6 is connected and fixed to the base 1 by bolts 9 and washers 10. During installation, it is first positioned by locating pins 11.

[0023] Specifically, the base 1 adopts a trapezoidal structure to stably support the rotor 17.

[0024] Specifically, the roller 2 has a rubber coating on its surface. The rubber coating of the roller 2 is in direct contact with the main shaft of the rotor 17, which is used to buffer the impact force of the rotor 17 falling and increase the friction force during the turning process, so as to avoid damage to the rotor 17.

[0025] Specifically, the bearing 7 has end caps 3 at both ends, which are fixed to the roller 2 by screws 8 to prevent foreign objects from entering the bearing 7 and keep the bearing 7 rolling smoothly.

[0026] The operation method of the rotor 17 support frame with the above-mentioned turning function is as follows: According to the model of rotor 17, adjust the distance between the rollers 2 and the two support components to meet the usage requirements, lift out rotor 17, and slowly lower the main shaft of rotor 17 to the middle of the two rollers 2. When turning is required, rotate rotor 17, and the two rollers 2 and rotor 17 drive each other to complete the rotation of rotor 17.
