Detailed Description

Hereinafter, a transfer device for a water turbine bearing according to the present invention will be described in detail with reference to the accompanying drawings and exemplary embodiments.

The utility model provides a transfer device for hydraulic turbine bearing. In an exemplary embodiment of the transfer device for a water turbine bearing of the present invention, as shown in fig. 1, the transfer device may include a plurality of sets of universal wheels 1, a bracket 2, a connection sleeve 3, a transfer rod 4, and a movable suspension ring 5. Wherein the content of the first and second substances,

the shown sets of casters 1 are arranged at the ends of the shown support 2. The shown sets of universal wheels 1 are used to move the transfer device. Further, as shown in fig. 1, two sets of universal wheels are provided at two ends of the support 2. Each group of universal wheels consists of a plurality of universal wheels.

The support 2 is arranged vertically and can be vertically arranged on the ground. The cross section of the bracket 2 along the first plane (paper surface) is in an inverted U-shaped structure, as shown in fig. 2. The holder 2 has a predetermined thickness along a second plane (perpendicular to the paper). The first plane and the second plane are arranged perpendicular to each other.

The connection sleeve 3 is arranged inside the bracket 2 at the position of the arc-shaped top of the bracket 2, as shown in fig. 2. The connecting sleeve 3 can be detachably connected with the bracket 2 or fixedly connected with the bracket. For example, the connection sleeve 3 may be welded to the bracket 2, or the connection sleeve 3 may be snap-fitted to the bracket 2. An opening is arranged at one end of the connecting sleeve 3, and a hollow structure communicated with the opening is arranged in the middle of the connecting sleeve.

One end of the transfer rod 4 may pass through the opening and be placed inside the hollow structure. In order to facilitate the removal of the transfer rod 4, the transfer rod 4 can be screwed to the adapter sleeve 3. In order to enable a better movement of the transfer device, the axial direction of the adapter sleeve 3 is arranged perpendicular to the first plane, i.e. the adapter sleeve 3 is perpendicular to the inverted U-profile of the holder 2. Because the transfer rod 4 is in straight line connection with the connecting sleeve 3, the transfer rod 4 is also perpendicular to the inverted U-shaped surface of the bracket 2.

The movable lifting ring 5 can be sleeved on the transfer rod 4. The mobile lifting ring 5 can be moved back and forth in the axial direction of the transfer bar 4, as shown in fig. 1.

When the bearing needs to be transported, the bearing needing to be transported is hoisted on the movable hoisting ring 5, and one end, far away from the connecting sleeve, of the transporting rod 4 is lifted manually so that the bearing is transported after being suspended. Because the indoor space of water machine is narrow and small, the transport rod 4 that sets up can be easier get into the water machine indoor, conveniently hoist and mount the bearing on removing rings 5.

In this embodiment, the transfer device may further comprise a bail 6. As shown in fig. 1, the bail 6 may be disposed at an end of the transfer rod 4 remote from the adapter sleeve. The lifting ring 6 can be fixedly connected with the transfer rod 4. The lifting ring 6 may be of an arc-shaped configuration. The two ends of the lifting ring 6 are arranged on the transfer rod 4. Because the lifting ring 6 is of an arc-shaped structure, a certain space is formed between the lifting ring 6 and the transfer rod 4. When the user needs to lift the transfer lever, the hand can be placed in the space for operation. In addition, the lifting ring 6 can prevent the movable lifting ring 5 from sliding out of the transfer rod 4.

In this embodiment, as shown in fig. 2, the stent 2 may include a first sub-stent 2a, a second sub-stent 2b, and a third sub-stent 2c connected to each other.
