Abstract
The utility model relates to an assistant tool used when a power plant guide vane servomotor body is maintained, in particular to a hydraulic power plant guide vane servomotor body maintenance supporting device. The maintenance supporting device is structurally characterized by comprising a supporting base, a supporting frame and rollers, the supporting frame comprises a left supporting frame and a right supporting frame, the left supporting frame and the right supporting frame are vertically mounted on two side edges of the supporting base respectively, the rollers are connected to the top ends of the left supporting frame and the right supporting frame through supporting bearings respectively, and the distance between the two rollers is two-thirds of the diameter of the servomotor body. Besides, a guide vane servomotor is supported by the aid of the supporting base and the supporting frames, and the rollers assist the servomotor body in rolling maintenance. The whole device is simple and light in structure, convenient to move and store, high in safety for equipment and staff in operation and high in structural strength and can be permanently used, maintenance cost is greatly saved, and working efficiency is improved.
Description
Technical field
The aid of using when the utility model relates to the guide vane servomotor body maintenance of a kind of power plant, particularly a kind of hydroelectric power plant's guide vane servomotor body maintenance supporting arrangement.
Background technology
When the guide vane servomotor body is overhauled, workpiece need be put in order in the hydraulic power plant, guide vane servomotor needs upset in maintenance process simultaneously.In the prior art, when overhauling, need some sleepers to be placed into operation site, then servomotor is placed on the sleeper, and relies on the revolving structure of servomotor self to overturn at sleeper.
Yet the weak point of technique scheme is: 1, in the practical operation scene, because the volume requirement of servomotor, need more sleeper, therefore also just need enough staff to cooperate carrying, manpower and materials have been wasted, and too much personnel have also caused on-the-spot confusion in that maintenance is on-the-spot, and all there are potential safety hazard in personnel and equipment; 2, the demand of sleeper is big, therefore also need for sleeper provides enough shallow storage space, and the storage condition of sleeper is higher, otherwise easily because the environment conversion causes damaging, deposits very inconvenience, has improved the cost of overhaul; 3, sleeper can only provide the plane, it is that line contacts with the servomotor body, surface to accurate rod member in operation impacts easily, and during the upset servomotor, owing to effectively do not connect between the sleeper, often take place sleeper crooked, upwarp, problems such as side is fallen, damages that fracture, therefore the servomotor body also can roll easily and land, and causes damage; In addition, firmly bigger during operation, need more operating personnel to operate together, so upkeep operation is very inconvenient, operating efficiency is low, cost of overhaul height (mainly being the amount of expending and a dead lift of sleeper), and operating personnel's personal safety had threat.
The utility model content
The purpose of this utility model is to provide a kind of hydroelectric power plant's guide vane servomotor body safe, that the cost of overhaul is low, overhaul efficiency is high to overhaul supporting arrangement according to the deficiencies in the prior art part.
The purpose of this utility model realizes by following approach:
Hydroelectric power plant's guide vane servomotor body maintenance supporting arrangement, its structural feature is, include support plinth, bearing support and cylinder, bearing support comprises left bearing support and right bearing support, uprightly be installed on the dual-side of support plinth respectively, the top ends of left side bearing support and right bearing support is connected with a cylinder by block bearing respectively, and the distance between two cylinders is 2/3rds servomotor body diameter.
During use, guide vane servomotor directly is placed on the cylinder of bearing support, support plinth and bearing support are used for supporting guide vane servomotor, and cylinder then is for auxiliary receiver body rolling maintenance.Like this, because the integrated structure of whole supporting arrangement, and simple structure, easy to operate, carrying need not to carry a large amount of sleepers easily again, has saved the cost of overhaul greatly; In addition, because the upset maintenance can directly be carried out at the supporting arrangement with cylinder, it is time saving and energy saving therefore to operate, and has also guaranteed the safety of equipment and the person, has improved overhaul efficiency.Selected two roller pitch are unlikely to rolling easily again and land from guaranteeing the booster action of cylinder to the servomotor body.
The utility model can further be specially:
Described block bearing is a kind of ball bearing, and it is positioned at cylinder both end sides place and has dust cap.
Consider that the guide vane servomotor weight that cylinder need support is big, therefore can select ball bearing, can either the big device of taking the weight of, and auxiliary receiver upset preferably.Dust cap is used for preventing that foreign matter from entering ball bearing, causes fault.
Also include a plurality of supports, it is connected between support plinth and the bearing support.
Like this, can reinforce supporting arrangement, enable better to be used for support and the maintenance of guide vane servomotor.
In sum, the utility model provides a kind of hydroelectric power plant guide vane servomotor body maintenance supporting arrangement, adopts support plinth and bearing support to support guide vane servomotor, and adopts then auxiliary receiver body rolling maintenance of cylinder.Single unit system is simple in structure, light and handy, and it is convenient to move and take care of, and in the operation equipment and personnel is all had very high security, and the structural strength height of supporting arrangement can forever use, and has saved the cost of overhaul greatly, has improved operating efficiency.
Description of drawings
Figure 1 shows that the structural representation of hydroelectric power plant described in the utility model guide vane servomotor body maintenance supporting arrangement;
Figure 2 shows that the vertical view of Fig. 1;
Figure 3 shows that the left view of Fig. 1, have partial sectional view.
Be described further below in conjunction with the utility model of embodiment.
The specific embodiment
Most preferred embodiment:
With reference to accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, hydroelectric power plant's guide vane servomotor body maintenance supporting arrangement, include support plinth 1, bearing support 2 and cylinder 3, bearing support 2 comprises left bearing support and right bearing support, uprightly be installed on the dual-side of support plinth 1 respectively, and adopt complex root support 4 to be connected between support plinth and the bearing support, be used for bracing means.The top ends of left side bearing support and right bearing support is connected with a cylinder by block bearing 5 respectively, and the distance that two cylinders are 3 is 2/3rds servomotor body diameter.Described block bearing 5 is a kind of ball bearing, and it is positioned at cylinder both end sides place and has dust cap 6.
It is material that cylinder adopts the A3 steel, and bearing load is 2.5T.
It is same as the prior art that the utility model is not stated part.
