Technical Field

[0001] The utility model relates to the technical field of rotor bearing installation, in particular to a rotor bearing installation auxiliary structure. Background Art

[0002] In modern mechanical equipment, bearings are a key component. They mainly support the rotation of large-load shafts and reduce the friction coefficient between the shaft and the mechanical structure during rotational motion. For long shafts, bearings can ensure the rotation accuracy during rotational motion. The rotor is a rotating shaft supported by bearings. It is generally used as the main rotating component in power machinery. Since rotating disk-like parts do not have a rotating shaft themselves, rigid connections or additional shafts are usually used. The disk-like parts and shafts can be regarded as rotors.

[0003] Most of the existing installation methods for rotor bearings are for workers to lift the rotor bearings and install them in alignment with the shaft. When the rotor bearings are large and heavy, it is more laborious and unstable for workers to lift the rotor bearings, which affects the efficiency of the alignment installation of the rotor bearings and the shaft.

[0008] In order to facilitate the clamping of the rotor bearing, as a preferred rotor bearing installation auxiliary structure of the utility model, the front side of the movable plate is fixedly connected to a support plate, the rear side of the support plate is fixedly connected to a second electric telescopic rod, and the rear side of the telescopic end of the second electric telescopic rod is fixedly connected to a clamping block.

By stably lifting the rotor bearing by the support plate 3, it is possible to avoid the problem that most of the existing installation methods of the rotor bearing are to lift the rotor bearing and align it with the rotating shaft. When the rotor bearing is large and heavy, it is more laborious for the staff to lift the rotor bearing and it is not stable enough, which affects the efficiency of aligning the rotor bearing with the rotating shaft.

[0026] As a technical optimization solution of the utility model, both sides of the top of the support plate 3 are fixedly connected with fixed blocks 10, the opposite sides of the two fixed blocks 10 are fixedly connected with the first electric telescopic rod 12, the surface of the telescopic end of the first electric telescopic rod 12 is fixedly connected with a push plate 15, and the side of the push plate 15 close to the movable plate 403 is fixedly connected to the movable plate 403.

[0027] In this embodiment, by controlling the telescopic end of the first electric telescopic rod 12 to extend, the push plate 15 can push the movable plate 403 and the support block 402, thereby achieving the effect of facilitating the movement of the support block 402.

[0028] As a technical optimization solution of the utility model, the front side of the movable plate 403 is fixedly connected to the support plate 11, the rear side of the support plate 11 is fixedly connected to the second electric telescopic rod 13, and the rear side of the telescopic end of the second electric telescopic rod 13 is fixedly connected to the clamping block 14.

[0029] In this embodiment: by controlling the extension of the telescopic end of the second electric telescopic rod 13, the clamping block 14 can be moved to push the rotor bearing backward until it contacts the clamping plate 401. At this time, the clamping block 14 and the clamping plate 401 will stably clamp the rotor bearing, thereby achieving the effect of conveniently clamping the rotor bearing.

[0030] As a technical optimization solution of the present invention, push rods 7 are provided on both sides of the rear side of the fixing plate 5 , and the front side of the push rods 7 penetrates the fixing plate 5 and is movably connected with the interior of the fixing plate 5 .

[0031] In this embodiment, the push rod 7 can be easily moved by being movably connected to the inside of the fixed plate 5, thereby achieving the effect of facilitating the movement of the push rod 7.

[0032] As a technical optimization solution of the present utility model, a handle 9 is fixedly connected between the rear sides of the two push rods 7 .

[0033] In this embodiment, the push rod 7 can be easily pushed by holding the handle 9, so that the support plate 3 and the rotor bearing on the top of the support plate 3 can be moved, achieving the effect of facilitating the movement of the support plate 3.

[0034] As a technical optimization solution of the utility model, third electric telescopic rods 8 are fixedly connected to both sides of the top of the base plate 1 , and the top of the telescopic end of the third electric telescopic rod 8 is fixedly connected to the bottom of the fixed plate 5 .

[0035] In this embodiment: by controlling the telescopic end of the third electric telescopic rod 8 to extend and retract, the height of the fixed plate 5 can be adjusted, so that the height of the push rod 7, the support plate 3 and the rotor bearing on the top of the support plate 3 can be adjusted, thereby achieving the effect of facilitating the adjustment of the height of the fixed plate 5.

[0036] As a technical optimization solution of the utility model, a push handle 6 is fixedly connected to the rear side of the fixed plate 5, and a universal wheel 2 is rotatably connected to the bottom of the base plate 1. There are four universal wheels 2 that are evenly distributed on the bottom of the base plate 1.

[0037] In this embodiment, by pushing the push handle 6, the universal wheel 2 at the bottom of the base plate 1 rotates, so that the base plate 1 and the rotor bearing on the top of the support plate 3 can be easily moved, thereby achieving the effect of facilitating the movement of the base plate 1.

[0038] Working principle: First, move the rotor bearing to be installed to the top of the support plate 3 so that the rotor bearing contacts the top of the support block 402. At this time, the telescopic ends of the two first electric telescopic rods 12 are controlled to extend at the same time, so that the telescopic ends of the electric telescopic rods push the push plate 15 and the moving plate 403 to move the two support blocks 402 to the opposite side, and lift the rotor bearing until the bottom of the center hole of the rotor bearing is at the top of the support plate 3, so that the rotating shaft can smoothly pass through the center hole of the rotor bearing. Then control the telescopic end of the second electric telescopic rod 13 to extend, so that the clamping block 14 can move to push the rotor bearing backward until it contacts with the clamping plate 401. At this time, the clamping block 14 and the clamping plate 401 will stably clamp the rotor bearing, and then push the push handle 6. At this time, the universal wheel 2 at the bottom of the base plate 1 rotates, so that the base plate 1 and the rotor bearing on the top of the support plate 3 can be conveniently moved to the vicinity of the required installation position, and then control the third electric telescopic rod 13 to extend. The telescopic end of the retractable rod 8 is extended and retracted to adjust the height of the fixed plate 5, so that the height of the rotor bearing on the top of the support plate 3 can be adjusted to the same horizontal position as the installation height of the rotating shaft, and then the push handle 6 is pushed again to move the bottom plate 1 to align the rotor bearing with the rotating shaft, and then the handle 9 is held and the push rod 7 is pushed. At this time, the support plate 3 and the rotor bearing on the top of the support plate 3 can be moved, so as to facilitate the insertion of the rotating shaft into the rotor bearing, and then the rotor bearing is knocked to make the rotor bearing and the rotating shaft tightly connected to complete the installation. By stably lifting the rotor bearing through the support plate 3, most of the existing installation methods for the rotor bearing can be avoided, that is, the staff lifts the rotor bearing and installs it in alignment with the rotating shaft. When the rotor bearing is large and heavy, it is more laborious for the staff to lift the rotor bearing, and it is not stable enough, which affects the efficiency of the alignment installation of the rotor bearing and the rotating shaft.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
