Problems solved by technology

[0003] However, due to the smoothness of the mushroom head, the power hand or the manipulator clamp cannot directly clamp it. Therefore, it is necessary to design an auxiliary lifting device that is easy to install, safe and stable, and easy to be clamped and operated by the power hand or manipulator clamp.

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as Figure 1-4 A hoisting device for long-distance clamping is shown, which includes an I-shaped tooling (4) and a fixing groove for the I-shaped tooling (4) matched on the mushroom head of the hoisting object (11).

[0033] The I-shaped tooling (4) includes a bottom plate (1), a grabbing handle (2) and an anti-off handle (3).

[0034] The bottom plate (1) is a rectangular flat plate, a grab handle (2) is arranged above the bottom plate (1), and an anti-off handle (3) is arranged above the grab handle (2). A spherical groove is arranged at the center of the lower bottom surface of the bottom plate (1). The base plate (1) and the grasping handle (2) are perpendicular to each other, and the base plate (1) and the anti-off handle (3) are parallel to each other.

[0035] The fixing groove of the I-shaped tooling (4) include...

Abstract

The invention relates to the field of nuclear fuel reprocessing, and particularly discloses a hoisting device used for remote clamping. The hoisting device used for remote clamping comprises an I-shaped tool and an I-shaped tool fixing groove formed in the mushroom-shaped head of a hoisted object in a matched mode. By adoption of the hoisting device, a power manipulator or a manipulator clamp canbe operated remotely to fix the I-shaped tool into the fixing groove in the hoisted object, and the hoisted object is vertically lifted through the I-shaped tool and then transferred onto the ground.The clamping surface of the hoisting device is smooth and thus beneficial to clamping, and the hoisted object can be kept stable and be prevented from shaking and falling in the clamping process.

Description

technical field [0001] The invention belongs to the field of nuclear fuel reprocessing, and in particular relates to a hoisting device for long-distance clamping. Background technique [0002] The radioactivity level in the spent fuel element shear hot cell is very high. In order to meet the exhaust requirements, the pre-exhaust filter element installed in the hot cell needs to be replaced regularly. The filter is installed next to the wall of the thermal chamber. The disassembly and replacement of the filter element must be performed remotely outside the hot chamber, and the environment in the hot chamber is complex. The original design uses the traditional hoisting method, locking the crane hanger with the mushroom head on the top of the filter element and pulling it out vertically , and the crane cannot travel to the vertical direction of the mushroom head of the filter element due to the limitation. If the filter core is clamped by the vertical wall of the power hand o...
