The utility model has the characteristics of convenient operation, low cost, function are various.
Description
Technical Field
The utility model relates to a thrust collar appurtenance, especially a multipurpose tool that is used for large-scale generator motor thrust collar.
Background
The thrust head of the generator motor is sleeved on the main shaft and is in interference fit with the main shaft, so that the installation and the disassembly are not convenient. The existing thrust collar hoisting is that a bridge crane is directly adopted to hoist the thrust collar onto a main shaft of a generator motor or to hoist the thrust collar out of the main shaft of the generator motor, so that the operation is very crude and violent, if the heating quantity of the thrust collar is insufficient or the main shaft of the generator is inclined, the main shaft of the generator is extremely easy to scratch in the hoisting process, the safety is low, and the maintenance cost is increased. Therefore, the existing thrust collar hoisting has the problems of easy damage to the main shaft of the generator and low safety.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a multipurpose tool for large-scale generator motor thrust collar. The utility model has the characteristics of difficult damage generator main shaft, security are high, the function is various.
The technical scheme of the utility model: the utility model provides a multi-purpose tool for large-scale generator motor distance head, includes fixed chassis, is equipped with a plurality of screw rods of being connected with the distance head along the circumferencial direction on the fixed chassis, is equipped with straining nut on the screw rod, and the top of fixed chassis is equipped with and is criss-cross reinforcement frame, and the lateral part of reinforcement frame is equipped with the barring sleeve of outside extension.
In the aforementioned multipurpose tool for the thrust collar of the large generator-motor, the reinforcing frame is composed of four fixing plates circumferentially distributed with the center of the fixing chassis as a circle center, and a reinforcing plate is arranged between adjacent fixing plates.
In the multipurpose tool for the large generator motor thrust collar, the top of the reinforcing frame is provided with the hoisting hole, and the hoisting hole is connected with the bridge crane through the hanging strip.
In the aforementioned multipurpose tool for the large generator motor thrust collar, the fixed chassis is further provided with bolts respectively connected with the generator main shaft and the lock ring on the generator main shaft.
Compared with the prior art, the utility model fixes the thrust collar by the screw rod and the tension bolt on the fixed chassis, realizes hoisting through the hoisting hole on the reinforcing frame, the bridge crane is not in direct contact with the thrust collar, is easy to adjust in the hoisting process, is not easy to damage the thrust collar and the main shaft of the generator, and has high safety; the thrust head is further accurately mounted and dismounted on the main shaft by screwing the tensioning bolt;
in addition, can also utilize the barring sleeve on the reinforcing frame to carry out the barring experiment to the unit, convenient operation, laborsaving, work efficiency is high, and firm in connection is stable, and operating safety factor is high.
The whole device has simple integral structure and low cost.
Therefore, the utility model has the characteristics of difficult damage generator main shaft, security are high, the function is various.

Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Example (b):
as shown in fig. 1, the multipurpose tool for the thrust collar of the large generator motor comprises a fixed chassis 1, a plurality of screws 2 connected with the thrust collar 42 are arranged on the fixed chassis 1 along the circumferential direction, tensioning nuts 21 are arranged on the screws 2, a cross-shaped reinforcing frame 3 is arranged above the fixed chassis 1, and a barring sleeve 31 extending outwards is arranged on the side part of the reinforcing frame 3.
The reinforcing frame 3 is composed of four fixing plates 33 which are circumferentially distributed by taking the center of the fixed chassis 1 as a circle center, and a reinforcing plate 34 is arranged between every two adjacent fixing plates 33.
And hoisting holes 32 are formed in the tops of the reinforcing frames 3, and the hoisting holes 32 are connected with a bridge crane through hanging belts.
The fixed chassis 1 is also provided with bolts 22 which are respectively connected with the generator main shaft 4 and a locking ring 41 on the generator main shaft 4.
The working principle is as follows: the fixed chassis 1 is connected with the thrust collar 42 through the screw 2 and the tensioning nut 21, the thrust collar 42 is hoisted onto the main shaft 4 through the reinforcing frame 3, then the fixed chassis 1 is fixed with the main shaft 4 and the locking ring 41 through the bolt 22, after the thrust collar 42 is sleeved in place and placed into the clamping ring 43, the tensioning nut 21 on the surface of the fixed chassis 1 is continuously tightened, and the thrust collar 42 is lifted, so that the upper plane of the thrust collar 42 is attached to the lower plane of the clamping ring 43; after the thrust collar 42 is installed, the long rod is installed on the barring sleeve 31, the long rod is used for pushing the fixed chassis 1 to rotate, so that the unit barring test is carried out, the barring is more convenient and labor-saving, and the working efficiency is improved.
When the thrust collar 42 is detached, a hanging strip is installed on the hoisting hole 32, and the hanging strip is connected with a lifting hook of a bridge crane for hoisting.
The part of the utility model not detailed is prior art.
