Problems solved by technology
[0008] The purpose of the present invention is to provide a small-radius shield operation propulsion compensation device to solve the first problem mentioned in the above background technology. The current compensation device mainly realizes compensation through the cam when feeding, and the stability is general, so it cannot The adjustment angle is precisely adjusted, and the control accuracy is insufficient; secondly, there is no auxiliary stabilizing member, and it is impossible to provide a stable guiding reinforcement for the feed assembly

The invention discloses a shield small-radius operation propulsion compensation device, relates to the technical field of engineering construction, and solves the problems that a compensation device used at present mainly realizes compensation through a cam during feeding, the adjustment angle cannot be accurately adjusted, and the control precision is insufficient. The shield small-radius operation propulsion compensation device comprises a main control disc seat, wherein a main body of the main control disc seat is of a triple flange structure; the main control disc seat is sequentially provided with bearing holes, assembly holes and pipe penetrating holes from outside to inside; the number of the bearing holes, the number of the assembly holes and the number of the pipe penetrating holes are all eight groups, and the bearing holes, the assembly holes and the pipe penetrating holes are arranged in a staggered mode; and a hydraulic control assembly is arranged in the middle of the top of the main control disc seat. According to the shield small-radius operation propulsion compensation device, an adjusting hydraulic cylinder is arranged, so that a compensation function is provided, compared with a cam compensation mode, the compensation function is more stable, the angle adjustment is more accurate, the angle deviation between the hydraulic cylinders can be avoided, the hydraulic cylinders can be prevented from being influenced by a parallel mechanism to deviate towards one side when the hydraulic cylinders are parallel, the stability degree is high, and high-precision control is facilitated.
Description
technical field [0001] The invention relates to the technical field of engineering construction, in particular to a propulsion compensation device for small-radius shield tunneling operations. Background technique [0002] The basic working principle of the shield machine is that a cylindrical steel component is pushed forward along the tunnel axis to excavate the soil. The shell of the cylinder assembly is the shield, which acts as a temporary support for the excavated unlined tunnel section, bears the pressure of the surrounding soil layer, and sometimes bears the pressure of the groundwater and keeps the groundwater out. Curved digging requires adjustment of the feed direction. [0003] After searching, for example, the patent No. CN211524824U discloses a non-damage automatic compensation device for shield small-radius operation propulsion protection segments, including hydraulic propulsion cylinders, support shoes, segments, and also includes connecting plates, push pla...
