Description
Technical Field
The utility model belongs to the technical field of coal mine production, concretely relates to entry driving machine carries supporting device.
Background
In the daily underground production process of a coal mine, the process cycle of the fully mechanized excavation operation is as follows: cutting → withdrawing → top of the upper-part of the shoes → temporary support → permanent support → recutting. When supporting temporarily, the current method is that many people cooperate manual operation: firstly installing two sets of top-picking frames and top-picking rings, then penetrating the top-picking rods, manually picking up the metal anchor nets and the steel bar beams through the top-picking rods to contact with the top plate, realizing temporary support in advance by not using top, then using an anchor rod machine to knock the top, assisting the anchor rods, installing anchor rod trays, and completing temporary support of the top plate. This kind of mode needs many people to cooperate, wastes time and energy, has reduced work efficiency, and workman's safety can not obtain the guarantee in the installation simultaneously, and is very dangerous to greatly increased manufacturing cost.
Disclosure of Invention
