Problems solved by technology
By setting the guide square steel in the piston rod, the piston rod is guided by the guide square steel when moving, which prevents the deflection of the piston rod when it is subjected to radial force. It has the following defects: the hollowing of the piston rod is inevitable Reduce its rigidity, thereby reducing the bearing capacity, and the structure is complex, and the processing cost is high

The invention discloses an embedded pocket-size anti-overturning single-oil-cylinder supporting shoe and belongs to the technical field of tunnel engineering. A problem that when single and double oil cylinders are alternately arranged in the prior art, due to the fact that the distance space of single and double oil cylinder supporting shoes is small, a single oil cylinder supporting shoe interferes with an adjacent double oil cylinder supporting shoe, and a double oil cylinder supporting shoe plate is often dragged out by a single oil cylinder supporting shoe plate is solved. The supporting boot comprises a supporting shoe plate body, wherein the supporting shoe plate body is fixedly installed at an end of a single oil cylinder, the top of the supporting shoe plate body is concaved inwards to form a sinking platform, and an elastic supporting assembly making contact with an inner wall of a tail shield is arranged in the sinking platform; the supporting shoe aims to solve a problem of deflection of a single-oil-cylinder gripper shoe when the distance between the existing single-oil-cylinder gripper shoe and the existing double-oil-cylinder gripper shoe is too small.
Description
technical field [0001] The invention belongs to the technical field of tunnel engineering, and in particular relates to an inlaid pocket anti-turnover single-cylinder support shoe. Background technique [0002] The propulsion system of the shield machine mainly provides the reaction force for the shield to make the shield tunnel forward. The reaction force pushes the cylinder against the segment, and the segment is stationary. By pushing the cylinder top segment, the shield is pushed forward. Adjust the stroke of the oil cylinder in some areas to change the direction of shield tunneling. [0003] In the shield construction process of tunnel engineering, due to the various divisions of segments, the arrangement of propulsion cylinders is also varied, including single-cylinder arrangement, double-cylinder arrangement, and single- and double-cylinder alternate arrangement. [0004] When the single and double cylinders of the oil cylinder are arranged alternately, the two pisto...
