Combined clamping device

Abstract

The invention discloses a combined clamping device. The combined clamping device comprises a telescopic mechanism, a main shaft sleeve and a grabbing head which are sequentially connected from top to bottom; a connecting rod is arranged in the main shaft sleeve in a penetrating mode, the lower end of the connecting rod is connected with the grabbing head, and the upper end of the connecting rod is connected with the telescopic mechanism. The telescopic mechanism drives the grabbing head to be opened and closed through the connecting rod. According to the mechanical gripper, the connecting rod is driven by the telescopic mechanism to move back and forth, and when the connecting rod stretches out, the gripper is opened; and when the connecting rod retracts, the gripping head is closed to grip the material. Due to the fact that opening and closing of the grabbing head have a large range, clamping operation of various materials can be achieved, different clamps do not need to be replaced for different materials, universality is high, working efficiency can be improved, and labor intensity of operators is relieved.

Description

technical field [0001] The invention relates to a clamping device, in particular to a combined clamping device. Background technique [0002] Spent fuel, also known as irradiated nuclear fuel, is nuclear fuel that has been exposed to radiation and used, usually produced by nuclear reactors in nuclear power plants. The nuclear fuel undergoes a nuclear reaction through neutron bombardment in the reactor, and is discharged from the reactor after a certain period of time. It contains a large amount of unused fertile material uranium-238 or thorium-232, unburned and newly formed fissile material plutonium-239, uranium-235 or uranium-233, and neptunium produced during the irradiation of nuclear fuel , americium, curium and other transuranium elements, in addition to fission elements strontium-90, cesium-137, technetium-99 and so on. The uranium content of this fuel is reduced and the nuclear reaction cannot continue, so it is called spent fuel. Spent nuclear fuel contains large...
