Technical Field

[0001] This utility model belongs to the field of nuclear power fuel core inspection tools, specifically relating to a portable, movable long pole tool holder for core inspection. Background Technology

[0002] On the temporary bridge above the reactor core of a nuclear power plant, long pole tools are typically used to connect and operate equipment such as rapid core photography devices. The main function of these long pole tools is to carry cameras to photograph the fuel assemblies in the core to identify the numbers on the assemblies and thus determine if the assemblies are in the correct position. This process is crucial for ensuring the safe operation of the nuclear reactor.

[0003] Due to the complex layout of components in the reactor core, traditional fixed mounting brackets cannot provide sufficient flexibility, limiting operators' ability to adjust tool positions and affecting the accuracy of image recognition. Especially when the camera position cannot be precisely controlled by adjusting the angle, it may lead to unclear identification of the fuel assembly numbers in the core, thus affecting the judgment of whether the assembly position is correct.

[0007] The aforementioned portable, movable long-pole tool holder for reactor core inspection is characterized in that a roller connecting shaft passes through a through hole in the middle of the roller, and a roller nut is connected to the tail of the roller connecting shaft to fix it to the upper part of the holder structure.

[0008] The aforementioned portable movable long rod tool holder for reactor core inspection is characterized in that grooves for installing roller bearings are provided on both sides of the roller, and the roller bushing is installed between the roller bearing on the right side and the holder structure.

[0009] The aforementioned portable, movable long-pole tool rack for reactor core inspection is characterized in that the support wheel mounting base is installed on the lower part of the rack structure by support wheel mounting bolts and support wheel mounting nuts.

[0010] The aforementioned portable, movable long-pole tool holder for reactor core inspection is characterized in that the support wheel is tightened and fixed to the support wheel connecting shaft via a support wheel connecting shaft nut.

[0011] The aforementioned portable, movable long-pole tool rack for reactor core inspection is characterized in that the support wheel has a built-in bearing, allowing the support wheel to roll freely along the railing during the rack's movement. The support wheel bushing is installed on the lower end face of the support wheel, providing a fixing function for the bearing on it.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The portable movable long-pole tool holder provided by this utility model for core inspection, on the one hand, allows the long-pole tool to move freely along the circular railing through a sliding design; on the other hand, the stability and support of the holder during lateral movement are ensured through components such as roller bearings and roller bushings; and on the other hand, the support wheel structure makes the installation and fixing of the holder simple and convenient, ensuring the firmness and safety of the holder during use.
