PLANE SLIDING ADVANCING DEVICE FOR SHIELD MACHINE

The present invention is directed to overcoming at least one of the deficiencies of the prior art, providing a plane sliding advancing device for a shield machine, wherein the advancing device comprises a supporting frame, a base plate provided on an upper side of the supporting frame and configured to support the shield machine, a plurality of sliding components and a plurality of resistance-increasing components provided on a lower side of the supporting frame, and a counterforce device provided at the tail end of the supporting frame, wherein the shield machine is provided with a telescopic device at one end. When a telescopic device is extended and advanced, the resistance-increasing component is activated to increase the resistance, so that the acceleration of the shield machine relative to a base plate is greater than the acceleration of a supporting frame relative to the ground; when the telescopic device contracts, the resistance-increasing component is activated to reduce the resistance, so that the acceleration of the shield machine relative to the base plate is less than the acceleration of the supporting frame relative to the ground. The advancing device of the present invention changes the friction between the advancing device and the ground according to different advancing processes, and is capable of realizing the continuous advancement, further saving energy consumption and reducing the construction cost.
