Short-distance material forking device

The utility model relates to the field of radioactive material transfer equipment, in particular to a short-distance material forking device. The device comprises a two-way telescopic assembly installed in a modularized mode, a lifting platform and a tray support. The two-way telescopic assembly comprises a first motor and a two-way pallet fork which are connected with each other; the lifting platform comprises a bottom plate, a top plate, a fork rod mechanism, a second motor and an upper and lower limiting sensor; sliding grooves are formed in the middle of the bottom plate and the middle of the top plate correspondingly, and the fork rod mechanism drives the rollers to slide in the sliding grooves through push-pull of the horizontal trapezoidal lead screws so that the platform can ascend and descend horizontally and stably. The second motor is connected with the lead screw and provides power for the lead screw. The upper and lower limiting sensors are fixed on the bottom plate; the upper portion of the top
