Opposite sliding occurs when featured oil cylinder stretches with tail shield C；It resets sliding block to design for round end, while can subtract under the action of the spring
Few impact of the shield tail C internal structure to sliding block is resetted in sliding process；When development machine is tunneled, it is located at middle shield and tail shield
The propelling cylinder of the junction C stretches out, and the shield machine support boots D of cylinder piston rod front end needs pushing tow on assembled section of jurisdiction, is
The driving of whole equipment provides thrust, and since the piston rod of oil cylinder itself can relatively rotate, shield machine supports boots D also can be therewith
It rotates, inside is designed using spring, and spring bottom resets sliding block and spring passes through studs connecting rod equipped with sliding block is resetted
It is attached with reset frame, for oil cylinder when stretching out, shield machine supports the reset sliding block at the both ends boots D under the action of the spring according to normal
Operating attitude shield machine support boots D is jacked up, rotary head is bonded with tail shield C inner surface, and when oil cylinder stretches with tail shield C generation phase
To sliding, and under the action of the spring, resetting sliding block can be as run trace of the shield machine support boots D on tail shield be stretched
Contracting.
The structure and working principle of the invention for being characterized by it and use operating method.
Compared with prior art, having can be to avoid the support boots of piston rod front end for a kind of shield machine support boots automatic reset device
Scraped finish phenomenon occurs with tail shield when rotating, reduces the impact to tail shield structure, solves the contact surface of support boots and section of jurisdiction end face
Product reduces, and the advantages that guaranteeing the normal operation of equipment, increase the efficiency of shield-tunneling construction, will be widely used in tunneling boring tunnel digging
Into in machine field of engineering technology.
Detailed description of the invention
