Description
Technical Field
The utility model belongs to the technical field of mechanical assembly, concretely relates to electric actuator straight stroke dismouting device.
Background
In a certain nuclear power station, two WWER-1000 type units in a first stage of engineering are provided with 34M ЗП -63000/25-100-00A-M З ", M ЗП -63000/40-160-00A-M З" and M ЗП -25000/25-100-00A-M З "type adjusting valve electric actuators which are all matched with an" 304521.006 "type straight stroke, the disassembly overhaul period of the straight stroke matched with the electric actuators is consistent with that of the electric actuators, and in each unit material change overhaul, at least 8 electric actuators in the straight stroke are subjected to comprehensive disassembly overhaul.
The linear stroke structure of the electric actuator is complex, the size is heavy, and the disassembly and the assembly are time-consuming and labor-consuming. The straight-stroke upper and lower gland is connected with the straight-stroke shell through threads and used for limiting axial displacement of the ball screw nut in the straight stroke, and in order to improve the straight-stroke sealing property, sealant is required to be coated on the threads when the upper and lower gland are installed. Because most of the electric actuators are installed on the valve of the high-temperature system in the straight stroke, after a major repair period of operation, lubricating grease in the straight stroke is dried up, threads are thermally bonded, and thread sealant is dried up and cured, so that the upper gland and the lower gland in the straight stroke are difficult to disassemble, the gland can be screwed out only by knocking a screwdriver and knocking at the same time, and the gland and the straight stroke threads are easily damaged in the mode, and the disassembly inspection work of the straight stroke is influenced; in addition, when the adjustable vertical hole hook wrench is used for unlocking the lower gland on a straight stroke, the adjustable vertical hole hook wrench is not strong enough to unscrew the gland, the adjustable vertical hole hook wrench can be damaged by forced operation, the adjustable vertical hole hook wrench can be separated from the vertical hole in the gland in the rotating process, and personnel operation injury can be caused under severe conditions.
Therefore, the straight stroke dismounting device is designed and manufactured independently according to the structural characteristics of the straight stroke, two self-reserved holes are formed in the straight stroke bottom pressing cover, the two self-reserved holes are used as the acting points of a special spanner, the special spanner is designed according to the structure of the straight stroke output threaded sleeve, the problem that the straight stroke bottom pressing cover cannot be dismounted is solved, the problem of dismounting the straight stroke output threaded sleeve is solved, the working time of dismounting and mounting of the electric actuator is shortened, the straight stroke dismounting efficiency of the electric actuator is greatly improved, and mechanical injury of personnel in the operation process can be avoided.
Disclosure of Invention
The utility model provides a technical problem:
aiming at the problems that the linear stroke of the electric actuator is heavy and cannot be normally disassembled and inspected due to the fact that the components are thermally bonded when the linear stroke assembly of the electric actuator runs in a high-temperature environment for a long time, and meanwhile, when the adjustable vertical hole hook wrench is used for disassembling the linear stroke gland of the electric actuator, the adjustable vertical hole hook wrench can be damaged, and personnel operation injury can be caused under serious conditions; the utility model provides an electric actuator craspedodrome journey dismouting device, stable in structure is reliable, and application method is simple, colludes the quick accurate dismouting electric actuator craspedodrome journey of spanner when using than general adjustable perpendicular hole, and according to the structural feature of electric actuator craspedodrome journey, the dismouting device intensity of design is suitable simultaneously, the one-man operation of being convenient for, and can not cause personnel's operation injury.
The utility model adopts the technical proposal that:
the utility model provides an electric actuator straight stroke dismouting device, includes handle, ring, round convex pin, square piece, and handle, round convex pin, square piece welding are on the ring.
The handles are welded to both axial sides of the ring.
Two round convex pins are welded on the section of the ring.
The position of the round convex pin corresponds to the position of the self-remaining hole of the straight-stroke bottom gland.
And two square blocks are welded on the section of the other side of the ring.
The distance between the square blocks is determined according to the size of the flat end face of the straight stroke output threaded sleeve.
The utility model has the advantages that:
aiming at the problems that the electric actuator straight stroke assembly is heavy in weight, runs in a high-temperature environment for a long time and is not normally disassembled and inspected due to hot adhesion of parts, the utility model provides an electric actuator straight stroke disassembling and assembling device which is stable and reliable in structure, simple in use method and capable of quickly and accurately disassembling the electric actuator straight stroke; meanwhile, the device can greatly reduce the disassembly and assembly time, improve the working efficiency and avoid the mechanical injury of personnel in the operation process.
