Transportation and overhauling device for nuclear industry

Abstract

The invention relates to a transportation and overhauling device for a nuclear industry. The transportation and overhauling device structurally comprises a transferring trolley and a conveying platform, and the transferring trolley is arranged on the conveying platform and can move relative to the conveying platform; the transferring trolley comprises a trolley body, a stop pin driving part and atrolley body driving part; and the trolley body comprises a trolley main body, a first stop pin shaft, a second stop pin shaft, a connecting rod mechanism and a driven gear, the stop pin driving partcomprises a first motor, a rotating shaft and a rotating piece, and the trolley body driving part comprises a second motor, a lead-screw screw rod and a lead-screw nut. According to the technical scheme, two-section conveying of a front stop pin, a rear stop pin and a nuclear equipment supporting piece is achieved, and the nuclear equipment supporting piece can be accurately conveyed into the preset position in a non-power section; in the whole transferring process, the gravity of the nuclear equipment supporting piece is always borne by the platform, the transferring device no longer has thesuspended position to bear force, and pressing and folding are prevented; and the other technical effects that the motors in the technical scheme can be externally arranged, and the number of the motors can be decreased are achieved.

Problems solved by technology

[0002] At present, most of the traditional equipment transfers are carried by hand, but for some heavy and large mechanical equipment, it will become difficult to use manual transfer, especially for those that need to be transferred from one work area that can be manually operated to another. Work areas where manual operations are performed, such as the handling of nuclear facilities

[0003] Chinese patent application publication CN106219137A discloses a movable transition device in a nuclear equipment transfer device and its method. The transfer device passes through the first wall through the movement of the input mobile trolley and cooperates with the unpowered roller support frame, but This technical solution has the following problems: 1. Due to the large mass of the object to be transferred, the precise positioning of the object to be transferred on the unpowered roller support frame requires high coordination between the moving speed of the moving trolley and the rotation speed of the powered roller

2. Also due to the large mass of the object to be transferred, the input moving trolley will be in a suspended state when it is matched with the unpowered roller support frame, and the suspended part needs to bear the gravity of the object to be transferred. Bending, so multiple support wheels are added to the technical solution of the public document, thereby increasing the complexity and difficulty of matching of each device

[0004] In addition to the above-mentioned difficulty in handling, another problem applied in nuclear facilities is the replacement of damaged equipment. Due to the reasons and limitations of the working environment, the motor in the nuclear equipment transfer device is prone to need to be replaced, so the nuclear equipment transfer The number of motors in the installation should be kept to a minimum and be easily replaceable
