Abstract

The invention relates to the technical field of pipe piece erectors for tunneling, in particular to a pipe piece erector grabbing device which comprises a grabbing beam, a first driving mechanism for driving a rotating shaft to rotate and a pressing disc located below the grabbing beam. A second driving mechanism for driving the pressure plate to move up and down is connected between the pressure plate and the grabbing beam; the rotating shaft comprises a rotating rod penetrating through the pressing disc, the lower end of the rotating rod is provided with a grabbing head which penetrates through an insertion opening in the duct piece, stretches into a grabbing cavity of the duct piece and rotates, the grabbing head is located below the pressing disc, and the grabbing head is provided with a stopping face which is arranged upwards and matched with the upper cavity wall of the grabbing cavity in a stopping mode. The pressing disc is provided with a pressing face which is arranged downwards and used for pressing the segment surface and is matched with the stopping face to clamp the segment. Automatic operation can be achieved, the duct piece bolt does not need to be screwed into a duct piece bolt hole manually, the duct piece bolt does not need to be hung on a lifting appliance manually, efficiency is higher, and the safety of workers can be guaranteed.

Description

technical field

[0001] The invention relates to the technical field of segment assembling machines for tunnel excavation, in particular to a grabbing device for a segment assembling machine. Background technique

[0002] After the shield machine excavates the tunnel, it is necessary to install the segment in the tunnel to prevent the tunnel from collapsing. The segment is transported into the tunnel through the segment conveying track, and then transported to the back of the cutter head by the segment hanger, and finally the pipe behind the cutter head The segment assembling machine installs the segments in the corresponding positions, that is, the segment assembling machine assembles the segments into a section of pipeline, and the segments need to be picked up before assembling the segments. At present, the grasping device of the assembly machine can be mainly divided into two types: vacuum suction cup type and mechanical type.

[0003] For example, the Chinese invention ...
