Coal mine roadway filling gob-side entry retaining anchor net supporting equipment

Abstract

The invention discloses coal mine roadway filling gob-side entry retaining anchor net supporting equipment. The equipment comprises an execution operation end (1), a connecting mechanism, a telescopicand rotary supporting mechanism (0), a bottom frame (6), an anchor net supporting frame (5), a sliding driving mechanism (7), an anchor net roll supply mechanism and an anchor net fixing mechanism. By arranging the anchor net roll supply mechanism and the anchor net fixing mechanism, an anchor net can be automatically laid on the roadway side wall to be supported through the supporting equipment,the supporting effect of the anchor net is effectively guaranteed, the anchor net can be tightly attached to the roadway side wall, and the supporting effect is guaranteed.

Description

technical field [0001] The invention specifically relates to a coal mine roadway filling gob-side roadway retaining anchor net support device, and relates to the related field of roadway support equipment. Background technique [0002] At present, during coal mining, structures such as bolts and anchor nets are generally used to support the roadway. The anchor rod is generally drilled with drilling equipment to set the anchor rod hole, and the anchor rod can be sent into the anchor rod hole. When the anchor net is supported, the anchor net needs to be evenly spread on the side of the road in order to realize Reliable support for the side of the road, however, because the anchor net is a relatively hard steel mesh structure, it is very inefficient to use manual support and laying during support and laying, and it is easy to scratch the hands of the layer , and ordinary equipment is difficult to be used in the support and laying of the anchor net, which makes the laying more ...

The anchor rod is generally drilled with drilling equipment to set the anchor rod hole, and the anchor rod can be sent into the anchor rod hole. When the anchor net is supported, the anchor net needs to be evenly spread on the side of the road in order to realize Reliable support for the side of the road, however, because the anchor net is a relatively hard steel mesh structure, it is very inefficient to use manual support and laying during support and laying, and it is easy to scratch the hands of the layer , and ordinary equipment is difficult to be used in the support and laying of the anchor net, which makes the laying more troublesome. Moreover, it is difficult to make the anchor net and the side wall of the roadway tightly fit during laying, which affects the support effect and support. ability to protect
