Abstract

The invention provides ceiling protection equipment for a TBM. The ceiling protection equipment comprises a ceiling body, a supporting mechanism and a lifting mechanism, wherein the supporting mechanism comprises a base, a stand column and a mounting column, the stand column and the mounting column are fixed to the base in parallel, a rib plate is arranged between the stand column and the base, the lifting mechanism comprises an oil cylinder fixed to the mounting column, a piston rod of the oil cylinder is fixedly connected with the ceiling body through a bearing ring, the stand column is fixedly connected with the bearing ring through a telescopic assembly, the telescopic assembly comprises a piston barrel and a barrel cover, a circular groove is formed in the upper end face of the standcolumn, the barrel cover is arranged in the groove, and the piston barrel penetrates through an inner hole of the barrel cover to extend into the groove of the stand column.

Description

technical field [0001] The invention relates to a ceiling protection equipment for a TBM roadheader, belonging to the technical field of tunnel excavation equipment. Background technique [0002] The TBM roadheader is a full-face hard rock roadheader used to excavate tunnels or roadways. In the actual roadway excavation process of the traditional TBM roadheader, the top of the tunnel will loosen when the bolter is driving the bolt, which will cause the rock Falling, and because there is no protective device in the working area of ​​the rock bolter, it will cause great harm to the personal safety of the staff, affect safe production, and affect work efficiency to a certain extent. Therefore, it is particularly important to provide an effective method for the roof protection device of the TBM roadheader. The roof protection device is located in the working area of ​​the bolter drilling machine, which ensures the personal safety of the staff and improves the work efficiency. ...
