Description

Maintenance support device for guide vane servomotor body of hydropower plant

technical field

The utility model relates to an auxiliary tool for overhauling the main body of a guide vane servomotor in a power plant, in particular to a support device for overhauling the main body of a guide vane servomotor in a hydropower plant.

Background technique

When the body of the guide vane servomotor is overhauled in a hydropower plant, the workpieces need to be placed in an orderly manner, and the guide vane servomotor needs to be turned over during the maintenance process. In the prior art, when performing maintenance, a number of sleepers need to be placed on the operation site, and then the servomotor is placed on the sleepers, and the servomotor is turned over on the sleepers by its own rotary structure.

Yet the weak point of above-mentioned technical scheme is: 1, in actual operation site, because the volume requirement of servomotor, needs more crossties, therefore also just needs enough staff to cooperate with carrying, wasted manpower and material resources, and too much 2. The demand for sleepers is large, so it is necessary to provide enough storage space for sleepers, and the storage conditions of sleepers are high, otherwise It is easy to be damaged due to environmental changes, and storage is extremely inconvenient, which increases the maintenance cost; 3. The sleeper can only provide a plane, which is in line contact with the servomotor body, which is easy to affect the surface of the precision rod during operation, and the servomotor is turned over Because there is no effective connection between the sleepers, the sleepers often have problems such as skewing, upturning, sideways falling, broken damage, etc., and the servomotor body will easily roll over and fall to the ground, causing damage; in addition, the operation requires a lot of force. Therefore, the maintenance operation is very inconvenient, the work efficiency is low, the maintenance cost is high (mainly the consumption of sleepers and manual handling), and it is a threat to the personal safety of the operators.

Utility model content

The purpose of the utility model is to provide a hydropower plant guide vane servomotor body maintenance support device with high safety, low maintenance cost and high maintenance efficiency according to the deficiencies of the prior art.

The purpose of this utility model is achieved by the following approach:

The key point of the structure of the maintenance support device for the guide vane servomotor body of a hydropower plant is that it includes a support base, a support frame and a roller. The support frame includes a left support frame and a right support frame, which are installed upright on both sides of the support base. The top ends of the support frame and the right support frame are respectively connected with a roller through support bearings, and the distance between the two rollers is two-thirds of the diameter of the servomotor body.

When in use, the guide vane servomotor is placed directly on the roller of the support frame, the support base and the support frame are used to support the guide vane servomotor, and the roller is used to assist the overhaul of the servomotor body. In this way, since the whole supporting device is an integrated structure, and the structure is simple, the operation is convenient, the handling is easy, and there is no need to carry a large number of sleepers, which greatly saves the maintenance cost; in addition, because the overturning maintenance can be carried out directly on the supporting device with rollers, so The operation saves time and labor, and also ensures the safety of equipment and personal, and improves the maintenance efficiency. The selected distance between the two rollers can ensure the auxiliary effect of the rollers on the servomotor body, and it will not be easy to roll and fall to the ground.

The utility model can be further specifically described as:

The supporting bearing is a kind of ball bearing, which is provided with dust-proof covers at both ends of the drum.

Considering the heavy weight of the guide vane servomotor that the drum needs to support, ball bearings can be selected, which can not only support heavy components, but also better assist the servomotor to turn over. The dust cover is used to prevent foreign matter from entering the ball bearing and causing malfunction.

It also includes a plurality of brackets, which are connected between the support base and the support frame.

In this way, the support device can be reinforced so that it can be better used for the support and maintenance of the guide vane servomotor.

To sum up, the utility model provides a supporting device for overhauling the servomotor body of a hydropower plant, which uses a support base and a support frame to support the servomotor, and uses a roller to assist the overhaul of the servomotor body. The overall device is simple and light in structure, easy to move and store, and has high safety for equipment and personnel during operation. The support device has high structural strength and can be used permanently, which greatly saves maintenance costs and improves work efficiency.
