Embodiment 1

[0040] This embodiment provides a pull rod, such as figure 1 - Figure 5 As shown, it includes: pull claw 1, core rod 2 and adjustment mechanism, pull claw 1 is used to grab fuel rods, pull claw 1 and core rod 2 are connected through an adjustment mechanism, and the adjustment mechanism is suitable for adjusting pull claw 1 and core rod 2 The pull rod also includes a pipe fitting 3, the core rod 2 is set in the pipe fitting 3, one end of the pipe fitting 3 is against the pull claw 1, and the pull claw 1 is suitable for entering or exiting one end of the pipe fitting 3.

[0041] Wherein, the pipe fitting 3 comprises a clamping tube 14 and a sleeve tube 15 clamped with the clamping tube 14, the clamping tube 14 is arranged between the sleeve tube 15 and the pull claw 1, and the adjustment mechanism is located in the clamping tube 14, and the axial dimension of the clamping tube 14 is smaller than the sleeve 15; it should be noted that in this embodiment, the specific structure of...

Embodiment 2

[0060] The rod drawing machine of the present embodiment, as figure 1 As shown, it includes the pull rod described in Embodiment 1, and also includes a slide mechanism 16 and an installation platform 17, and the pull rod 18 is arranged between the slide mechanism and the installation platform 17. Since the pull rod 18 is provided with an adjustment mechanism, the distance between the pull claw 1 and the core rod 2 is shortened or extended by the adjustment mechanism, and then the length of the pull claw 1 extending out of the pipe 3 is adjusted, so that each pull rod can be connected to the end plug of the fuel rod. 19 snap-in, and snap-in at the correct position.

[0061] Compared with the traditional rod pulling machine, which manually moves the fuel rod to connect the fuel rod end plug 19 to the tie rod, the rod pulling machine in this embodiment can greatly save manpower, has low labor intensity, and has higher working efficiency.

Abstract

The invention relates to the technical field of fuel preparation, in particular to a pull rod and a rod pulling machine with the same. The pull rod comprises a pull claw, a core rod and an adjusting mechanism, the pull claw is used for grabbing a fuel rod, the pull claw is connected with the core rod through the adjusting mechanism, and the adjusting mechanism is suitable for adjusting the distance between the pull claw and the core rod; the pull rod further comprises a pipe fitting, the core rod is arranged in the pipe fitting, one end of the pipe fitting abuts against the pull claw, and thepull claw is suitable for entering or disengaging from one end of the pipe fitting. According to the pull rod, the distance between the pull claw and the core rod is shortened or prolonged through theadjusting mechanism, then the length of the pull claw extending out of the pipe fitting is adjusted, all the pull rods can be connected with a fuel rod end plug in a clamped mode and connected to thecorrect positions in a clamped mode, therefore the pull rod greatly saves manpower, and is low in labor intensity and higher in operation efficiency.

Description

technical field [0001] The invention relates to the technical field of fuel preparation, in particular to a pull rod and a rod pull machine with the same. Background technique [0002] Nuclear fuel is a very important clean energy source. The rod pulling process of nuclear fuel rods is generally to pull the fuel rods with a length of about 4m through the grid in the framework layer by layer until all the fuel rods are installed in the grid. This kind of equipment that realizes the rod drawing process is generally called a rod drawing machine. [0003] Existing rod pulling machines generally include an installation platform, and a pull rod, a slide mechanism and a rod selection mechanism located on the installation platform. When working, the rod selection mechanism selects the first pull rod, and the slide mechanism drives the first pull rod to move Reciprocating motion on the installation platform. Specifically, the pull rod passes through the fuel assembly framework inst...
