Force bearing monitoring device for sandy cobble stratum shield hob

Abstract

The invention discloses a force bearing monitoring device for a sandy cobble stratum shield hob. The device comprises a transverse pressing block and a longitudinal pressing block. The longitudinal pressing block is fixedly connected on one side of the transverse pressing block. The top end of the transverse pressing block is provided with a transverse slide groove. A transverse slide block is slidably connected on the inner side of the transverse slide groove. A longitudinal slide groove is arranged at the top end of the longitudinal pressing block. A longitudinal slide block is slidably connected on the inner side of the longitudinal slide groove. A planar bearing pressing block is connected on the top ends of the longitudinal slide block and the transverse slide block. A first fastening screw rod is screwed on the top end of the transverse pressing block. A first fixing side plate is screwed on the outer side of the first fastening screw rod through threads. The planar bearing pressing block and the slope compressing block are arranged so that the problem that the force bearing monitoring device for the shield hob is not convenient to firmly fix the rotating shaft of the hob with different sizes when the force bearing monitoring device for the shield hob is used and the use effect of the force bearing monitoring device for the shield hob is affected can be avoided.

Description

technical field [0001] The invention belongs to the technical field of force monitoring devices, and in particular relates to a device for force monitoring of a hob of a shield machine in a sandy pebble formation. Background technique [0002] Fine sand and large pebbles can be mixed together. During the formation of the alluvial fan, because the energy of the water is released quickly at the moment of exiting the mountain mouth, the sediment transported by the water body accumulates rapidly, which is not as good as in a normal river. sorting. Rock stratification is a sandy pebble formation formed in a certain pressure and time geological environment; the hob is affected by forces in three directions during actual work, based on the contact point between the hob and the rock, including The normal force in the radial direction of the hob, the rolling force in the vertical radial direction, and the lateral force in the axial direction. Too much force on the hob is prone to t...
