Description
Technical field
The utility model relates to straight-cylinder piston type servomotor overhaul field, power station, particularly a kind of piston type servomotor moving-out device.
Background technology
The power part of Adaptive System of Water-Turbine Engine and control normally adopts hydraulic relay device, due to the difference of structural shape, as the servomotor of Hydraulic Elements, can be divided into piston type servomotor and scraper-type servomotor two kinds, piston type servomotor is divided into again straight-cylinder piston type and ring piston type.The servomotor of these different structure type, again with straight-cylinder piston type servomotor be used in turbine gate mechanism operation control the most extensive.
In maintenance, mainly there is following problem, 1 in straight-cylinder piston type servomotor), labour intensity, security risk be large.The straight-cylinder piston type servomotor in most of power station all level is arranged in water machine layer servomotor lining hole on soleplate, and maintenance tunnel is not designed in rear end, for servomotor front end leakage of oil situation, does not need whole servomotor body to shift out, now can process.If there is leakage of oil situation in servomotor rear end, as hydraulic generator machine overhauling classification is repaiied following at B, generator upper spider will not be removed, overhead traveling crane equipment cannot in placely lift, and just needs 6 technical staff spend 3 day time, manually by being arranged on water wheel chamber small space, the servomotor body of nearly 1.5 tons of weights shifts out, also need artificial by servomotor installation in position after maintenance, not only labour intensity is very large, has a strong impact on unit maintenance duration progress, also easily ruins thing casualty accident.2), servomotor burst leakage of oil event, power generation loss is larger.Process is traditionally overhauled servomotor and is needed 72 hours consuming time, in wet season unit oepration at full load situation, as servomotor occurs that leakage of oil need be carried out shutting down, abandoning water repairing, not only affects economic benefit, also reduce equipment reliability, year utilization rate.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of straight-cylinder piston type servomotor moving-out device, and make the repair time of servomotor short, security risk is low, and not easily people occurring is security incident, and this moving-out device can use for a long time.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of piston type servomotor moving-out device, comprise servomotor leading-out portion and servomotor tractive unit, described servomotor leading-out portion contains three screw rods and a ring flange bracing frame, described ring flange bracing frame is evenly distributed with three for being inserted in the disk hole of screw rod; Described servomotor tractive unit structure is: i-beam track is provided with pulley, is connected with electric block under described pulley.
Further, angle bar is fixed with below described i-beam track two ends.
Further, one end that described screw rod is inserted in ring flange bracing frame has pin hole.
Compared with prior art, the beneficial effects of the utility model are: the first, save time, and increase economic efficiency.The servomotor overhaul of traditional approach and pressure testing need 72 hours consuming time, and adopt the utility model device consuming time less than 7 hours, can shift to an earlier date 65 hours and complete service work.The second, labour intensity is reduced.Traditional servomotor overhaul needs 6 skilled workers, and 72 hours consuming time, only need 4 people now, 7 hours consuming time, also substantially increase overhaul of the equipments progress.
