Abstract

The invention provides a quick soil pressure sensor replacing device which comprises a sleeve, a sensor installation seat, a sluice gate installation seat, a sluice gate, a closing oil cylinder and atelescopic oil cylinder, wherein the inside of the sleeve is hollow, the sensor installation seat shares the same central axis with the sleeve and is detachably arranged in an inner cavity of the sleeve, the sluice gate installation seat is arranged on the sleeve in the radial direction of the sleeve, the sluice gate is arranged on the sluice gate installation seat and can seal the inner cavity ofthe sleeve in the radial direction, the closing oil cylinder is used for controlling the sluice gate to be opened and closed, and the telescopic oil cylinder is connected with the sensor installationseat and can control the sensor installation seat to move in the axial direction of the sleeve. The quick soil pressure sensor replacing device disclosed by the invention has the advantages of high automation degree, simple structure, convenience in control, ability in quickly and safely replacing a soil pressure sensor under the situation that a soil warehouse is under pressure, good sealing effect, high safety and ability in improving soil pressure sensor replacing efficiency.

Description

technical field [0001] The invention belongs to the field of shield machinery for tunnel construction, and in particular relates to a quick replacement device for an earth pressure sensor. Background technique [0002] In the process of excavating tunnels with earth pressure balance shield machines or mud-water balance shield machines, in order to control surface settlement, the pressure in the soil chamber of the shield machine must be reliably detected, and earth pressure sensors are usually used to detect the pressure of the soil chamber in real time , the PLC program controls parameters such as the propulsion speed of the shield machine and the unearthed volume of the screw machine according to the pressure collected by the earth pressure sensor. Therefore, the pressure in the soil bin has a great influence on the parameters and efficiency of the shield machine's excavation. [0003] In the construction of underground tunnels, the medium in contact with the earth pressur...
