A main drive sealing runway automatic adjustment device

Abstract

The present invention proposes an automatic adjustment device for a main drive sealed raceway, which includes a sealed raceway, the sealed raceway is axially movably connected to a drive disc, and an axial adjustment unit is arranged between the sealed raceway and the drive disc. Positive and beneficial effects of the present invention: the present invention establishes a real-time monitoring system for the temperature and wear of the sealed runway to monitor the temperature of the sealed runway in real time. When the temperature is too high and exceeds the alarm value, an alarm signal is triggered to prompt the staff to overhaul the sealing system. When the wear of the sealed runway exceeds a certain value, the upper computer generates an alarm, triggers the runway movement signal, activates the oil pressure system, and the runway can automatically move about 5-10mm to the side of the soil bin. The sealed runway avoids serious wear and tear, and a new matching size between the seal and the runway can be re-established to achieve a good sealing effect, providing a strong safety guarantee for shield construction.

Description

technical field [0001] The invention relates to the technical field of excavation and construction of a tunnel shield machine, in particular to an automatic adjustment device for a main drive sealed runway. Background technique [0002] With the rapid development of urban infrastructure, building groups and underground pipe networks are becoming increasingly dense, shield machines are playing an increasingly important role as the main equipment for current tunnel construction. The main drive main bearing is the core component of the shield machine, and its normal operation is a prerequisite and an important guarantee for tunnel construction. The main drive seal acts as a barrier between the main bearing and the outside world, and plays a vital role in the normal operation of the equipment. Since there is currently no monitoring method for the sealed runway of the main drive, if the sealing temperature is too high or the runway is excessively worn during the operation of the...

Problems solved by technology

[0004] The present invention proposes an automatic adjustment device for the main drive sealed runway, which solves the current situation that the sealing temperature and wear cannot be monitored in real time, and workers need to enter the warehouse to adjust the sealed runway. The operation of adjusting the sealed runway is complex, dangerous and subject to soil pressure. The problem of restrictive conditions
