本发明属于可弯曲式掩护筒掘进机的改进。 以前,在可弯曲式掩护筒掘进机的前壳体和后壳体之间,且沿外壳内每隔一定间隔设置数个弯曲用的油缸。当前壳体对后壳体弯曲时,分别控制各个油缸的伸缩量。 这种可弯曲式掩护筒掘进机外壳内设置油缸存在着以下问题:①有空隙以及构造复杂化;②必须一次控制所有的油缸;③在前壳体和后壳体之间是插销式连接,如果这部分进入砂土,工作效率就会减弱。 本发明就是要解决以上存在的问题。在掩护筒主体的前壳体和后壳体之间,插入绕
The invention pertains to an improvement of a bendable shield tunneling machine. Previously, between the front shell and the rear shell of the bendable shield boring machine, a plurality of cylinders for bending were provided at regular intervals along the shell. When the front shell is bent toward the rear shell, the amount of expansion and contraction of each cylinder is separately controlled. Such a flexible casing TBM housing provided with the cylinder there are the following problems: ① there is a gap and the structure is complicated; ② must control all of the cylinder; ③ between the front and rear housing is a bolt-type connection, If this part into the sand, work efficiency will be weakened. The present invention is to solve the above problems. A winding is inserted between the front case and the rear case of the screen main body
