Hydraulic shield machine segment assembly device

Abstract

The invention provides a segment assembling device for a hydraulic shield tunneling machine. The segment assembling device comprises a translation system, a rotary system, a lifting system, a fine-tuning system and a grasping system, wherein the translation system is in transition connection with the rotary system through a movable disc body; the rotary system is in transition connection with the lifting system through a rotary disc body; the lifting system is in transition connection with the fine-tuning system through a center joint ball bearing; the fine-tuning system is in transition connection with the grasping system through a fine-tuning shaft. The segment assembling device has the advantages that various actions do not interfere with each other when rolling, pitching and deflection are carried out, so that the stability of the system is improved; the rotary system is connected with the translation system through a single-row four-point-contact ball type slewing bearing, so that vibration of the rotary system is reduced; a simple automatic grasping system is designed, so that grasping is relatively convenient.

Description

technical field [0001] The invention relates to a tunnel engineering construction machine, in particular to a hydraulic shield machine segment assembling device. Background technique [0002] The segment assembly device is one of the important components that need to be used in tunnel construction. After the shield tunneling machine advances forward, it must be spliced ​​with prefabricated segments to form a tunnel lining to protect the excavated tunnel surface. Therefore The function of the segment assembly device will also directly affect the quality of assembly and the progress of construction. [0003] The segment assembling device is mainly composed of a translation system, a rotary system, a lifting system, a fine-tuning system and a gripping system. After searching the existing documents, it was found that the publication date is September 27, 2006, and the publication number is CN1837578A. The patent discloses a six-degree-of-freedom shield segment assembly machine....

AI Technical Summary

Problems solved by technology

The six-degree-of-freedom operation realized by the above-mentioned method mainly has the following disadvantages: 1. The force of the entire segment counterweight is carried by four moving pairs, so high-power and high-precision moving pairs must be used during use, which leads to cost 2. In addition to the axial force, the mobile pair also has to bear the bending torque force, which can easily lead to problems such as the piston of the mobile pair being stuck or the piston rod broken, which is not conducive to the smooth progress of the project, and will Bring certain safety problems; 3. The slewing system will vibrate when it is subjected to radial force and overturning force, which will reduce the stability of the system

The fine-tuning system of the above invention has the following disadvantages: 1. Only one segment tilting oil cylinder and one segment rotating oil cylinder are used to realize the rotation of the segment, so that the load on the segment tilting oil cylinder and the segment rotating oil cylinder is relatively large, which will reduce the overall tube load. The load capacity of the segment assembly machine; 2. When the segment tilting cylinder is working, the rotating platform is not fixed, and it may shake, causing the segment to be dislocated. Of course, when the segment rotating cylinder is working, it may also bring redundant 3. The rotary system will vibrate when it is subjected to radial force and overturning force, which also reduces the stability
