Embodiment 1

[0027] This embodiment provides a pressure head structure of an overpressure machine, including a pressure head 1 arranged in a hot chamber, such as figure 1 As shown, it also includes a pull rod 3. Specifically, a threaded hole is provided inside the pressure head 1, one end of the pull rod 3 is screwed with the threaded hole inside the pressure head 1, and the other end of the pull rod 3 is fixed in the hot room; this embodiment The indenter structure of the overcompressor in the heat chamber can realize the rapid disassembly of the indenter 1 by rotating the pull rod 3 at one end of the hot chamber outside the hot chamber.

[0028] In this embodiment, the pressure head structure of the overcompressor further includes a hydraulic cylinder, wherein the lower end face of the cylinder body 2 of the hydraulic cylinder is in contact with the pressure head 1, and the pull rod 3 penetrates the interior of the cylinder body 2 of the hydraulic cylinder; The hydraulic cylinder is the ...

Embodiment 2

[0036] This embodiment discloses an overpressure machine used in a radioactive environment, including the pressure head structure of the overpressure machine in Example 1.

[0037] The overpressure machine used in the radioactive environment of this embodiment can realize the remote and rapid disassembly of the pressure head outside the hot room, so as to ensure the normal operation of the overpressure machine.

Abstract

The invention discloses a pressure head structure of an overpressure machine, which includes a pressure head arranged in a hot chamber and a pull rod, wherein a threaded hole is arranged inside the pressure head, and one end of the pull rod is connected with a thread inside the pressure head. The holes are screwed together, and the other end of the tie rod is fixed outside the heat chamber. The invention also discloses an overpressure machine used in a radioactive environment, including the above-mentioned pressure head structure of the overpressure machine. The pressure head structure of the overpressure machine of the present invention can realize the long-distance quick disassembly of the pressure head outside the hot room.

Description

technical field [0001] The invention specifically relates to a pressure head structure of an overpressure machine and an overpressure machine used in a radioactive environment. Background technique [0002] The rays are shielded by thick shielding partitions inside and outside the hot chamber. The overcompressor is generally used to compress compressible radioactive solid waste. Then it moves on both sides of the shielding partition. When the pressure head of the ordinary overpressure machine is repaired and replaced, it needs to be disassembled directly by the staff, and the radioactive environment in the hot room makes it impossible for the staff to enter the hot room for disassembly and replacement. Difficulties. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide an indenter structure of an overpressure machine and an overpressure machine used in a radioactive environment for the above-mentioned deficiencies in ...
