Problems solved by technology

There are many kinds of grabs on the market for loading and unloading goods on the ground, but this type of grab is generally not suitable for underwater operations, and it cannot be used for those with high requirements for liquid environments.
The other is the underwater grip often used in seawater. The grip is large in size. Although it is suitable for underwater operations, it has high requirements for the liquid environment in the reactor and is afraid of being polluted. This device is also not applicable. Moreover, the existing grabbers generally cannot perform operations such as flipping during the grabbing process.

Embodiment Construction

[0010] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0011] The device is installed on the crane by the long rod 5 in the device, and the device is sent to the underwater designated position by the crane. The long rod 5 is fixedly connected with the sealed gearbox 2 through the flange 6, and the sealed gearbox 2 is connected with the horizontal rotating frame 3 through the shaft, the bearing and the gear pair 7 in the gearbox, and is supported on the horizontal rotating frame 3. On the sealed gearbox 2, the horizontal rotation drive motor 1 fixed on the gearbox 2 is brought to the horizontal rotation frame 3 to rotate through the gear pair 7 in the transmission gearbox 2, so as to realize the rotation of the gripper in the horizontal plane.

[0012] The vertical rotation drive motor 4 is supported on the horizontal rotation frame 3, and is connected with the vertical rotation frame 11 through bear...

Abstract

The invention discloses a subsurface electric gripper comprising a motor, a gear box (2), a screw mandrel, a fixture (13), a frame, and a pole (5). The motor is divided into a horizontal rotation drive motor (1), a vertical rotation drive motor (4) and a clamping motor (12). The pole (5) is fixedly connected on the gear box (2). The horizontal rotation drive motor (1) is connected with a horizontal rotation frame (3) by the gear box (2), and the vertical rotation drive motor (4) is connected with a vertical rotation frame (11). The vertical rotation frame (11) is installed on the horizontal rotation frame (3) by a shaft. The fixture (13) is installed on the vertical rotation frame (11). The clamping motor (12) is connected with the fixture (13) by the screw mandrel. The horizontal rotationframe (3) is equipped with a camera device (9). The invention is smaller in volume, free from pollution, and suitable for subsurface operation.

Description

technical field [0001] The invention relates to the technical field of reactor engineering, in particular to an electric underwater gripper. Background technique [0002] At present, grabs can be divided into two types: grabs for loading and unloading goods on the ground and grabs for grabbing items underwater. There are many kinds of grabs on the market for loading and unloading goods on the ground, but this type of grab is generally not suitable for underwater operations, and it cannot be used for those with high requirements for liquid environments. The other is the underwater grip often used in seawater. The grip is relatively large. Although it is suitable for underwater operations, it has high requirements for the liquid environment in the reactor and is afraid of being polluted. This device is also not applicable. Moreover, the existing grippers generally cannot perform operations such as turning over during the grabbing process. Contents of the invention [0003]...
