Embodiment

[0022] An adjustable clamping tool designed by the present invention. The realization of the clamping function of the tool is similar to the principle of brake line braking. The main structure includes an operating handle, a long rod (a combination of multiple aluminum alloy tubes), a brake line, a clamp, and a fixing folder. Use the operating handle and the brake cable to control the opening and closing of the clamp, select the appropriate length by adding or subtracting the aluminum alloy tube (connected by spring buckle), change the fixing clip according to the different clamping objects, and adjust the brake cable tension control clamp at the operating handle Sustain strength.

[0023] The working principle of the present invention is: the replaceable fixing clip 6 is fixed with a screw and the clamp 5, and a suitable replaceable fixing clip 6 is replaced according to the clamped object; the hollow aluminum alloy tube 2 uses a reducing diameter and a spring clip 3 to realize ...

Abstract

The invention belongs to the technical maintenance field of nuclear power plants, and particularly relates to an adjustable clamping tool. The tool comprises an operating handle, a plurality of hollowaluminum alloy tubes, a connecting spring clamping sleeve, a plurality of steel wire brake wires, a clamp and a plurality of replaceable fixing clamps, the operating handle is connected with one endof the hollow aluminum alloy tube through a connecting spring clamping sleeve, the other end of the hollow aluminum alloy tube is connected with the variable diameter of the connecting spring clampingsleeve, the steel wire brake cable is arranged in the hollow aluminum alloy pipe, one end of the steel wire brake cable is fixedly connected with one end of the clamp, and the replaceable fixing clamp is fixedly connected with the other end of the clamp. The adjustable clamping tool is designed, the electrode core of the electric contact type liquid level meter can be clamped at a long distance,so that the device can be inserted into a designated hole to be fixed, the clamping length can be adjusted through modular design, the characteristics of different fixing clamps can be replaced according to different clamping objects, and the universality of the tool is improved.

Description

Technical field [0001] The invention belongs to the technical maintenance field of nuclear power plants, and particularly relates to an adjustable clamping tool. Background technique [0002] An electric contact type liquid level gauge was used in the sewage drainage pump room of a nuclear power plant for liquid level monitoring and the drainage pump was linked for drainage. The electrode core of the level gauge is longer, so the electrode core is fixed by the channel steel with openings in the pit to avoid the bending of the electrode core and affect the normal drainage function of the pit. This type of level gauge needs to extract the entire electrode core during inspection and regular maintenance, and reinstall it after the inspection or maintenance is completed. The channel steel opening of the fixed electrode core is small, only slightly larger than the diameter of the electrode core, so it cannot be directly aligned and inserted and fixed. Due to the design of the plant, ...
