Technical Field
The utility model relates to a nuclear power equipment field, concretely relates to device is put in inspection of big specification axle type part.
Background
At present, large-size shaft parts such as a main bolt of a nuclear reactor pressure vessel, a CRDM tube seat and the like are inspected by adopting a rolling mode on a platform, the labor intensity of an operator is high, the inspection efficiency is low, a phosphorization layer on the surface of the main bolt is easy to damage, and the main bolt is easy to collide and scratch. To overcome the defects in the prior art, a device for checking and placing large-specification shaft parts is needed.
Disclosure of Invention
The utility model provides a device is put in inspection of big specification axle type part overcomes the not enough of prior art.
The technical scheme adopted by the utility model is a large-specification shaft part checking and placing device, which comprises a base, a movable beam and a nylon roller carrier; the movable cross beam is transversely arranged on the base, a longitudinal waist-shaped hole is formed in the base and used for the movable cross beam to longitudinally move along the base, the nylon roller carrier is arranged on the movable cross beam, and a transverse waist-shaped hole is formed in the movable cross beam and used for the nylon roller carrier to transversely move along the movable cross beam; the nylon roller carrier comprises a bracket, a nylon roller, a shaft, a bearing and a puller bolt; the puller bolt penetrates through the bracket to abut against the nylon roller and is used for limiting the rotation of the nylon roller.
The movable cross beams are 2 groups and are arranged on the base at intervals, and the longitudinal distance of the 2 groups of movable cross beams is adjusted to be used for matching the placement of the shaft parts to be inspected.
The nylon gyro wheel frame be 4 at least, accessible adjustment nylon gyro wheel frame lateral distance for the cooperation is waited to inspect putting of axle type part.
The utility model has the advantages that: by adopting the placing device, the labor intensity of an operator can be reduced, the efficiency is improved, the phosphate coating can be prevented from being damaged and the part can be prevented from being collided and scratched in the process of rotating the part, and the placing device has high universality.
Drawings

Detailed Description
The utility model will be further explained with reference to the accompanying drawings 1-3, as shown in fig. 1, a large-size shaft part checking and placing device comprises a base 3, a movable beam 2 and a nylon roller frame 1; the base 3 is formed by welding channel steel and other section steels, the movable cross beams 2 are transversely installed on the base 3 at intervals, and longitudinal waist-shaped holes are formed above the base 3; the movable cross beam 2 longitudinally moves along the waist-shaped hole on the base 3; the opening range of the waist-shaped hole is suitable for the longitudinal movement of the movable cross beam 2, and the movable cross beam 2 is provided with a transverse waist-shaped hole; the nylon roller carrier 1 is arranged on the movable cross beam 2 and can transversely move along a waist-shaped hole on the movable cross beam 2; the opening range of the waist-shaped hole is suitable for the transverse movement of the nylon roller frame 1. The nylon roller carrier 1 comprises a nylon roller 5, a bracket 4, a bearing 7, a shaft 6 and the like, and the nylon roller 5 has small rotation resistance; referring to fig. 3, in the structure diagram of the nylon roller frame 1, a nylon roller 5 is sleeved on a shaft 6 and fixed on a bracket through a bearing 7, the nylon roller frame 1 is provided with a puller bolt 8, and the puller bolt 8 passes through the bracket 4 and abuts against the nylon roller 5 to limit the rotation of the nylon roller 5.
When large-specification shaft parts such as a main bolt of a nuclear reactor pressure vessel, a CRDM pipe seat and the like are inspected, the large-specification shaft parts can be easily rotated to be inspected by horizontally placing the large-specification shaft parts on 4 nylon roller frames; when the main bolt is checked by the go-no go gauge, the jacking bolt can be screwed down to limit the rotation of the nylon idler wheel; by adjusting the longitudinal distance of the movable cross beam and the transverse distance of the movable roller carrier, the device is suitable for placing the stack type main bolts such as CPR1000, AP1000, ACP1000, CAP1400 and the like and CRDM tube seats, and has higher universality.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be within the technical scope of the present invention, and the technical solutions and the inventive concepts of the present invention are equivalent to or changed according to the present invention, and all those are included in the scope of the present invention.
