The invention discloses a semi-chute type connector for an F-shaped steel rail.The connector comprises a lower connecting plate and a limiting boss.The limiting boss is arranged on one side face of the lower connecting plate.The surface of the protruding end of the limiting boss is a plane.Wing plates of the F-shaped steel rail are each correspondingly provided with a vertical-through groove matched with one end of the limiting boss.A long-strip-shaped gap formed by the through grooves of the two opposite wing plates and the gap between the two through grooves is used for allowing the limiting boss on the lower connecting plate to be inserted therein.Connecting pieces penetrate through connecting holes to fixedly connect the lower connecting piece with the wing plates, so that the limiting boss penetrates through the long-strip-shaped gap, the surface of the protruding end of the limiting boss is flush with the upper surfaces of the wing plates, the side face of the limiting boss makes complete contact with the inner walls of the through grooves in the wing plates, and then F-shaped steel rail connection is achieved.According to the connector, it can be ensured that a wheel is not disengaged from the wing plates all the time, impact of the rail gap on the walking wheel can be completely avoided, and meanwhile additional high-difficulty machining and strength or performance weakening do not need to be carried out on the structure of the F-shaped steel wing plates.
