Abstract

The invention relates to a novel hydraulic rotation mechanism of a segment erector. The novel hydraulic rotation mechanism comprises a filter, a plunger pump, a check valve, an electric-hydraulic proportional direction valve, an overflow valve, a first pressure reduction valve, a second pressure reduction valve, a pressure gauge, a pressure sensor, a shuttle valve, a balance valve, a three-position ball valve, a two-way overflow valve, an energy accumulator, two hydraulic motors, a brake and a rotary encoder. A balance control module of the hydraulic motors is composed of the balance valve and the two-way overflow valve, and two-way safety protection can be provided; the pressure compensation type electric-hydraulic proportional direction valve with loads is selected for use, and precision and stability of the splicing position are ensured; the hydraulic motors with mechanical braking are adopted, and reliability of rotation movement is ensured; and the hydraulic impact generated in the start, stop and reversing processes of the segment erector is eliminated, the device damage situation such as the situation that the novel hydraulic rotation mechanism gets stuck is effectively prevented in the movement process, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to an underground shield construction equipment, in particular to a hydraulic rotary mechanism of an earth pressure balance shield machine segment assembling machine. Background technique [0002] The segment assembly machine system of the shield machine is a large-scale electromechanical-hydraulic integrated construction machinery system with high power, high control precision requirements, and variable load. The hydraulic system is one of the important indicators for evaluating the segment assembly system of the shield machine. The rotation time of the piece assembly machine accounts for 50-60% of the entire segment installation cycle time, and the energy consumption accounts for 30-50%. Therefore, it is necessary to reasonably determine the hydraulic oil circuit scheme of the slewing mechanism and correctly select many parameters of the slewing mechanism. It is of great significance to improve productivity and power utilization...
