Boiler water cold wall pipe detection probe clamping device

Abstract

The invention relates to a boiler water cold wall pipe detection probe clamping device. A step type through hole structure which has the communicated upper and lower side and is used for placing a probe is formed in the center of a case; a coupling agent exerting hole is formed in the casing and at one side of the step type through hole structure; one end of the coupling agent exerting hole is positioned in one side surface of the casing, and is connected with an external coupling agent exerting device; the other end of the coupling agent exerting hole is connected with one end of a coupling agent guide pipe positioned in the casing; the other end of the coupling agent guide pipe is positioned in the bottom surface of the casing; a downwards recessed probe wire groove communicated with the step type through hole structure is formed in one side, far away from the coupling agent exerting hole, of the upper end surface of the casing; the bottom surface of the casing is of an inwards recessed arc-shaped surface capable of being anastomotic with a measured pipe; the four end corners of the casing are respectively provided with guide wheels capable of rolling along the tested pipe. The boiler water cold wall pipe detection probe clamping device has the advantages that the coupling agents can be automatically exerted in the field detection process; the probe can be automatically regulated along the radian of the detection surface in the detection process; the tight attachment with the detection surface is ensured all the time; the detection precision and the detection efficiency are greatly improved.

Description

technical field [0001] The invention relates to a clamping device for a wall tube detection probe. In particular, it relates to a clamping device for detecting probes of boiler water-cooled wall tubes used in chemical industry, petrochemical industry, medicine, metallurgy and other industrial fields. Background technique [0002] During the long-term service process of the water-cooled wall tube in the boiler of the power station under the environment of high temperature, high pressure and medium corrosion, it is corroded and scoured by water vapor, flue gas, coal ash and flame medium, and various corrosion defects and cracks will occur on the tube wall and thinning phenomenon. Due to the impact of the on-site testing environment, the current probes for water-cooled wall tube testing are generally small in size, which has caused great difficulties for the testing personnel to carry out testing on the spot, it is difficult to ensure the accuracy of the testing, and it is not...

Problems solved by technology

Due to the impact of the on-site testing environment, the current probes for water-cooled wall tube testing are generally small in size, which has caused great difficulties for the testing personnel to carry out testing on the spot, it is difficult to ensure the accuracy of the testing, and it is not convenient for the testing process. Application of couplant

[0003] At present, in the detection process of boiler water wall tubes, the commonly used probe clamping method is hand-held. This method has the following problems: ①The size of the probe is small, and it is not easy for the detection personnel to ensure the stability of the probe during the detection process; It is tightly attached to the water wall, which causes great inconvenience to the on-site inspection personnel and has a great impact on the detection accuracy; ②Due to the influence of on-site inspection conditions, it is not convenient to apply the coupling agent during the inspection process, which has a relatively large impact on the inspection efficiency Impact
