Description
Technical Field
The utility model relates to the field of hydraulic turbine maintenance of hydropower stations, in particular to a special tool for decomposing an oil separator of a swing type servomotor.
Background
In the prior art, the disassembly work of the oil separator of the guide vane servomotor of the hydropower station belongs to one work which is troublesome and easy to damage equipment in the past overhaul work. Because the guide vane servomotor is arranged in the waterwheel chamber, the internal environment is very humid, and the maintenance period is longer, so that the outer sleeve of the oil separator and the piston are severely corroded.
The upper jacket decomposition method comprises the following steps: in the past, the oil separator is decomposed by welding a simple support on an upper jacket of the oil separator, then arranging a jack between a piston in the upper jacket and the simple support, lifting the top edge of the jack, heating the upper jacket of the oil separator by using gas welding, slowly pulling the upper jacket of the oil separator away from the piston of the oil separator in the heating process, then removing the simple support by using gas welding, and polishing the welded part of the upper jacket of the oil separator by using an angle grinder to recover the surface smoothness.
The lower coat decomposition method comprises the following steps: the simple bracket is welded on the lower outer sleeve of the oil separator after being processed, and the lower outer sleeve of the oil separator is decomposed by a decomposition method of pulling the upper outer sleeve.
The two guide vane servomotor oil separators are arranged in each unit, and the oil separators are decomposed and overhauled by the method, so that not only is the manpower, material resources and financial resources wasted, but also the precious overhauling period is wasted, and the problems that the outer jackets of the oil separators are damaged or deformed, the oil separators cannot be used or leak oil and the like are possibly caused. The original technological method and tools are easy to cause equipment damage, low in working efficiency, easy to cause environmental pollution and the like.
Disclosure of Invention
The utility model aims to provide a special tool for decomposing the oil separator of the swing type servomotor, which has reasonable structure, simple and convenient operation, simplified procedure, increased efficiency and good use effect.
The technical scheme of the utility model is as follows: the special tool for decomposing the oil separator of the swing type servomotor is characterized by comprising a tray body with three holes, wherein three claw pull rods which are uniformly distributed are screwed on the tray body, the upper ends of the claw pull rods are provided with threads, the upper ends of the claw pull rods penetrate through the three holes of the tray body and are connected with the tray body through nuts, and the lower ends of the claw pull rods are provided with hooks which are hooked with the outer sleeves of the lower parts of the oil separators of the servomotor. Is provided with a jack.
The utility model has the advantages that: 1. the tool is simple and convenient to operate, the investment of manpower and material resources is greatly reduced, and the overhaul period of the guide vane servomotor oil separator decomposition work is shortened. 2. By adopting the special tool, the damage or deformation of the outer sleeve of the oil separator of the servomotor is avoided, the equipment processing time is saved, the labor cost is saved, the use cost and the electric charge of the generated electric welding equipment and electric tool equipment in the welding and processing process are reduced, the equipment surface treatment, paint supplementing labor cost and material cost are reduced, the equipment acquisition cost is reduced, the sum of the above items is saved by 5 ten thousand yuan, and the economic effect is remarkable. 3. After the special tool is adopted, electric welding equipment and an electric polishing tool are not used, the hazard of fire is avoided, the probability of equipment damage and personnel injury is reduced, and the safety of overhaul work is greatly enhanced. 4. After the special tool is adopted, electric welding equipment and an electric polishing tool are not used, dust and toxic gas which are not generated are discharged, the influence on human bodies and the environment is greatly reduced, and the social value is remarkable.
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 present utility model in use.
Detailed Description
Referring to fig. 1 and 2, the names of the parts are as follows: the hydraulic oil distributor comprises a disc body 1, a claw pull rod 2, a nut 3, a jack 4, an upper outer sleeve 5 of the oil distributor of the servomotor, a lower outer sleeve 6 of the oil distributor of the servomotor, a hook body 7, a piston 8 and an oil distributor 9 of the servomotor.
Referring to fig. 1, the special tool for decomposing the oil separator of the swinging type servomotor comprises a tray body 1 with three holes, wherein three claw pull rods 2 which are uniformly distributed are screwed on the tray body 1, the upper ends of the claw pull rods 2 are provided with threads, the upper ends of the claw pull rods 2 penetrate through the three holes of the tray body 1 and are connected with the tray body 1 through nuts 3, and the lower ends of the claw pull rods 2 are provided with hooks 7 which are hooked with an outer sleeve 6 at the lower part of the oil separator of the servomotor. Is provided with a jack 4.
Manufacturing a disc body 1: the diameter of the disc body 1 is 500mm, three holes with the diameter of 30mm are uniformly formed in the disc body 1 along the circumference in the 120-degree direction, and the thickness of the disc body 1 is 20mm. The special triangular Lama type decomposing tool is formed.
And manufacturing a pull rod 2 with claws: the length of the claw-carrying pull rod 2 is calculated to be 800mm by considering the heights of the lower jacket 6 of the oil separator of the servomotor and the jack 4, and the thickness of the claw-carrying pull rod 2 is calculated to be 30mm. And a right-angle hook body 7 (or called pull claw) with the height of 20mm is integrally manufactured below the pull rod 2 with the claw, and a screw rod of M24 is welded at the other end of the pull rod 2 with the claw and a nut 3 is assembled.
The use method is that referring to fig. 2, three pull rods 2 with claws of the special tool are arranged according to the direction of 120 degrees, after a piston 8 is well protected and cushioned, a 32 ton jack 4 is placed, a tray body 1 is installed, the tray body 1 and the three pull rods 2 with claws are fixed firmly by a nut 3, one person operates the jack 4 to jack up, and the upper outer sleeve 5 of the oil separator of the servomotor and the lower outer sleeve 6 of the oil separator of the servomotor are pulled out together slowly, so that the disassembly is completed.
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.
