Detailed Description

The embodiments of the present invention will be described in detail with reference to the accompanying drawings:

a lifting type water pump rotor overhauling device is shown in figure 1 and comprises a lifting mechanism, wherein a bearing support is fixedly arranged above the lifting mechanism, two bearings are fixedly arranged on the bearing support in a bilateral symmetry mode, and a gap for supporting and placing a rotor is arranged between the two bearings; the lifting mechanism comprises: a nut, a screw and a handle; the nut is sleeved on the screw rod, the bearing support is fixedly arranged above the screw rod, handles for rotating the nut are symmetrically arranged on two sides of the nut, and the screw rod is driven to move up and down by rotating the nut so as to drive the bearing support to lift.

In this embodiment, the bearing support is rectangular, and the bilateral symmetry is provided with a clamping groove for fixedly mounting the bearing, and the bearing is fixedly mounted in the corresponding clamping groove.

In this embodiment, a first support plate is fixed to the bottom of the bearing support through a bolt, and the first support plate is fixed to the screw.

In this embodiment, the screw rod outside cover is equipped with the screw rod sleeve, adds bearing diagonal structure respectively in the telescopic both sides of screw rod, bearing diagonal structure top and second backup pad bottom are adorned admittedly, and this bearing diagonal structure's bottom is adorned with the base admittedly together.

In this embodiment, a limit bearing is mounted on the second support plate, an outer ring of the limit bearing is fixedly mounted on the second support plate, and an inner ring of the limit bearing is embedded with a nut; the second supporting plate is provided with a through hole for penetrating and installing a screw rod.

The utility model discloses a theory of operation and working process are:

the bearing bracket is manufactured by welding a baffle plate on a steel plate; the height of the screw and the nut can be adjusted according to actual conditions, so that the maintenance requirement is met; considering that the weight of part of the water pump rotor is larger, in order to stabilize the lifting device, inclined support structures are additionally arranged on two sides of the screw rod sleeve, the lower part of each inclined support structure is fixedly installed with the base, and the upper part of each inclined support structure is fixedly installed with the second support plate.
