Description

Motor end cover hoisting device

Technical Field

The utility model belongs to the technical field of electrical equipment, concretely relates to motor end cover hoist device.

Background

The medium-large motor inevitably breaks down in the operation process, partial faults can be eliminated only by disassembling and assembling the end cover, hoisting equipment such as a bridge crane is lacked in field maintenance, and equipment such as a steam crane cannot be used in part of maintenance fields due to space limitation. At present, when the motor maintenance operation is carried out on site and the end cover needs to be disassembled and assembled, the end cover is lifted by manpower or hoisted by using a cooler lifting lug, an L-shaped hoisting beam and a hoist; the labor intensity is high, the safety risk exists and the end cover is not suitable for hoisting the end cover with large mass by depending on manpower for disassembling and assembling the end cover.

If a hoisting mode of a cooler lifting lug 9, an L-shaped lifting beam 10 and a hoist crane 11 is adopted, only one L-shaped lifting beam of the existing end cover hoisting device is connected with the cooler lifting lug, the connection cannot independently bear the rotation moment formed by bearing the load of the tail end of a cantilever beam, so that the contact part of the L-shaped lifting beam and the cooler forms an acting force, the acting force is the largest when the end cover is retracted to the tail end of the L-shaped lifting beam, and the acting force is in direct proportion to the length of the L-shaped lifting beam in the horizontal direction and is generally multiple times of the gravity of the end cover; the cooler is a thin-wall welding part, has low structural strength and is likely to deform or damage; 2 hoist cranes need to be continuously adjusted in the movement of the end cover, and the operation is complex; the device is not suitable for hoisting the generator end cover of other cooling structures. The L-shaped hanging beam has large pressure on the cooler, the cooler is easy to deform or damage, 2 hoist cranes are required to be continuously adjusted to move the end cover, and the operation is complex.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses a motor end cover hoist device solves and lifts the poor, high scheduling problem of intensity of labour of end cover security with the manpower, solves and utilizes cooler lug, L type hanging beam and calabash to lift by crane the problem that the end cover easily harmed cooler, operation complicacy.

In order to achieve the above purpose, the technical scheme of the utility model is as follows:

a motor end cover hoisting device comprises upright posts positioned on two sides, wherein a guide rail cantilever is arranged at the top of each upright post, a rolling hoisting wheel is arranged in each guide rail cantilever, a cross beam is arranged between the rolling hoisting wheels of the two guide rail cantilevers, and a hoisting ring is arranged on the cross beam; every the centre of stand is provided with the bolt that is used for fixed motor end cover top rings, every the bottom of stand is provided with the bolt that is used for fixed motor end plate below through wires hole.

Furthermore, the upright post adopts two sections, and the two sections of the upright post are connected through a flange.

Furthermore, the tail end of the guide rail cantilever is provided with a limiting baffle.

Further, the rolling hanging wheel is arranged in a sliding groove of the guide rail cantilever.

The utility model has the advantages that:

1. the utility model discloses an unique structure can be the interface with top lug, the below through wires hole of motor frame end plate, realizes the hoist and mount of motor big quality end cover.

2. The utility model discloses a stand adopts components of a whole that can function independently structure, and is fixed through flange joint.

3. The utility model discloses the axial displacement of well hoisting point is realized through guide rail cantilever, rolling pulley.

4. The utility model has the overall structure of a 'door' shape.
