The invention discloses a spreader for an underground excavation trolley. The spreader comprises lifting plates, front connecting pieces, rear connecting pieces, first connecting rods and second connecting rods. When the spreader needs to work, the two second connecting rods are arranged in parallel in the width direction of the underground excavation trolley, and the two first connecting rods respectively sleeve two ends of the second connecting rods to form a quadrilateral above the underground excavation trolley; the front connecting pieces and the rear connecting pieces are arranged on twosides of the underground excavation trolley; upper ends of the front connecting pieces sleeve the second connecting rods, and lower ends are fixedly connected with front ends of crawler beams; upperends of the rear connecting pieces sleeve the second connecting rods, and lower ends are fixedly connected with rear ends of the crawler beams; four lifting plates sleeve ends of the second connectingrods and are fixed by nuts and gaskets; and steel wire ropes penetrate the lifting plates to be connected with the spreader. The spreader can improve efficiency of transporting the underground excavation trolley to a tunnel working face, and has good safety.
