The invention provides an advance speed control device for a shield tunneling machine. The device comprises a controller, a three-position four-way valve, a flow distributor and two propulsion jacks,wherein a displacement sensor is mounted on a push rod of each propulsion jack, and the displacement sensor is electrically connected with the controller, so that a displacement signal of each propulsion jack is transmitted to the controller; the flow distributor comprises an inlet and two outlets; the inlet of the flow distributor is connected with a working port of the three-position four-way valve; each outlet of the flow distributor is communicated with a rodless cavity of each propulsion jack, and a rod cavity of each propulsion jack is communicated with another working port of the three-position four-way valve; and the flow distributor is of an integrated structure. The advance speed control device for the shield tunneling machine, provided by the invention, is compact in structure,small in floor space and accurate in flow adjustment.
