Description
Technical Field
The utility model relates to a radial reaming platform of a hydroelectric generating set.
Background
In the prior art, in the reforming process of the hydro-generator set, the elevation of a large-sized fixing part (a generator stator) needs to be adjusted on a maintenance site to carry out radial drilling or reaming. Because the shape of the stator leads to that the magnetic drill base cannot be adsorbed on the surface of a workpiece, finished products meeting the function cannot be purchased in the market, and drilling or reaming under special conditions cannot be completed. The radial reaming platform of the stator of the unit is researched and manufactured by combining with the actual condition of the site, the position of the radial reaming platform can be adjusted according to the actual condition of the site, and the drilling or reaming under the special condition is completed.
Disclosure of Invention
The utility model aims to overcome the defects, and provides a radial reaming platform for a hydroelectric generating set, which is simple in structure and practical, and solves the problem of machining radial pin holes for stator positioning of the generating set.
The technical scheme of the utility model is as follows: the radial reaming platform of the hydroelectric generating set is characterized by comprising a base plate connected with an outer frame of a stator, wherein two screws are welded on the base plate; the adjustable magnetic drill adsorption platform is an iron plate, two key grooves connected with two screws are formed in parallel on the adjustable magnetic drill adsorption platform, and the adjustable magnetic drill adsorption platform is connected by nuts.
The key slot is 31mm wide and 1600mm long. The screw diameter M30 is 120mm long.
The utility model has the advantages that: 1. the device can not be completely adsorbed on the surface of a workpiece aiming at the situation that the contact area between the surface of the workpiece and the magnetic drill base is small, and reaming and drilling can be effectively carried out. 2. Reasonable in design, easy operation, with low costs, strong adaptability, convenient and fast, safe and reliable reduces intensity of labour, improves work efficiency.
Embodiments of the present utility model will be described in further detail below with reference to the accompanying drawings.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic view of the use state of the present utility model.
Detailed Description
Referring to fig. 1 and 2, the names of the parts are as follows: the magnetic drill comprises a base plate 1, an adjustable magnetic drill adsorption platform 2, a key groove 3, a screw 4, a nut 5, a stator outer frame 6 and a magnetic drill 7.
Referring to fig. 1, the radial reaming platform of the hydroelectric generating set comprises a base plate 1 connected with a stator outer frame 6, and four sections of channel steel 15cm multiplied by 1m can be buckled in a butt joint mode and horizontally placed and welded to form the base plate 1 because the shape of the stator of the set cannot meet radial reaming. Two screws 4 are welded on the base plate 1, the screws 4 are of a diameter M30 and a length of 120mm, and the adjustable magnetic drill adsorption platform 2 is connected by using an M30 nut 5. The adjustable magnetic drill adsorption platform 2 is an iron plate, and two key grooves 3 with the length of 31mm are formed in the iron plate with the thickness of 20mm and 2100mm multiplied by 2700mm and the parallel distance of 1600mm and are used as the adjustable magnetic drill adsorption platform 2. Two key grooves 3 connected with two screws 4 are formed in parallel on the adjustable magnetic drill adsorption platform 2, the width of each key groove 3 is 31mm, the length of each key groove is 1600mm, and the adjustable magnetic drill adsorption platform 2 is connected by a nut 5. Through welding the foundation plate 1 on the outer frame 6 of stator, the magnetic drill 7 base adsorbs on adjustable magnetic drill adsorption platform 2, satisfies radial drilling and reaming processing. The device is adjusted to finish drilling or reaming under special conditions. The labor intensity can be effectively reduced, and the working efficiency is improved.
When the magnetic drill base cannot be adsorbed on the surface of a workpiece completely in site, and the contact area between the surface of the workpiece and the magnetic drill base is small, the device can be adjusted to drill or ream under special conditions.
In the whole transformation process of the hydroelectric generating set of the power station, the device has excellent functions and is convenient for field application. The installation and the overhaul of the unit can meet a plurality of similar problems, and the problems of drilling, reaming and the like are solved. The device has the advantages of simple structure, convenient processing, small volume and low cost, can effectively shorten the operation time, reduce the labor intensity and improve the working efficiency. The device has great help to the installation and maintenance of the unit, has great popularization prospect, and is suitable for comprehensive popularization in industry.
The above description is only of specific embodiments of the present utility model, and the various illustrations do not limit the essential content of the present utility model.
