Abstract

The invention discloses a mobile support bracket of a tunneling machine, which comprises two bracket units that are arranged side by side front and back; each bracket unit comprises two bases respectively arranged at the two sides of the tunneling machine, and a top beam arranged above the tunneling machine, wherein a lifting mechanism used for supporting the top beam is connected between the bases and the top beam; the front end of the top beam is provided with a telescopic beam driven by a telescopic beam straight line driving mechanism; the front end of the telescopic beam is provided with shovel teeth; two side protecting plates driven by a side protecting plate straight line driving mechanism are respectively arranged at the two sides of the top beam in a sliding way; and a pushing device used for driving the bracket units to move is connected between the two bracket units. After the structure is adopted, the tunneling machine can be supported by the mobile support bracket, and the mobile support bracket can move along with the tunneling machine, so that the newly tunneled space is supported in time.

Description

technical field [0001] The invention relates to the technical field of coal mining, in particular to a mobile support bracket for a roadway boring machine. Background technique [0002] At present, in the process of coal mining, the roadway excavation is the first problem to be solved. The distance of the roadway after the roadway is excavated and before the bolt is very dangerous. If the conditions are good, the roadheader with supporting equipment is used. The unit is temporarily supported, so that it is easy to injure people when the roof falls, resulting in unsafe working conditions and relatively slow excavation speed. Contents of the invention [0003] The technical problem to be solved by the present invention is: to provide a roadway boring machine mobile support bracket for supporting the roadheading machine during the tunneling process. [0004] In order to solve the above technical problems, the technical solution of the present invention is: a roadway boring m...
