[0028] The heat conduction mechanism includes a heat conduction mold 21 disposed on the upper part of the heating cavity 41, and a heating coil 44 is clamped in the groove of the heat conduction mold 21;

[0029] The recovery mechanism includes an oil recovery chamber 51 disposed at the lower portion of the heating chamber 41 . The oil recovery chamber 51 has a plurality of transmission pumps 52 built therein. The liquid inlet end of the transmission pump 52 penetrates into the inner cavity of the heating chamber 41 .

[0030] It should be noted that: when the FRP grating needs to be heated and solidified, the heating mechanism is extended upward close to the mold, and the cylinder 11 drives the output end piston rod 12 to extend and drive the support plate 13 to rise. Slide seats 14 are installed at both ends of the support plate 13, and the slide seat 14 slides relative to the vertical rail 15.
