The invention is mainly used for underground coal mine roadway support.

Description

technical field [0001] The invention relates to an airborne hydraulic multifunctional temporary support machine. Background technique [0002] At present, when the coal mine roadway is developed, after the roadheader develops the roadway section, before the roadway is permanently supported, it is necessary to temporarily support the newly exposed roadway. There are two types of support used, one is artificial Support, the other is airborne support. The support machine is installed on the roadheader, and it works with the help of the hydraulic system on the roadheader. concerns about insecurity. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an airborne hydraulic multifunctional temporary support machine which can increase the support area and is suitable for construction under the conditions of front, rear, left and right slopes at the top of the roadway, and provides safe support. [0004] In order to solve t...
