Problems solved by technology

[0002] At present, mine disasters occur frequently in our country, so various armors are indispensable safety equipment for mining, and the mine protection net is the foundation of safety facilities. However, there are some problems with mine protection nets in our country. The material of some mine protection nets is Steel wire has toughness but insufficient rigidity, and there are hidden dangers in the protection of some large-volume falling objects, while other protective nets are made of steel bars, which can meet the requirements in toughness and rigidity, but the cost of use has increased significantly

Abstract

The invention belongs to a protective net, and particularly relates to a mine protective net. The mine protective net comprises a device body which is mainly composed of steel wires and steel bars. The mine protective net is characterized in that a framework of the mine protective net is rectangular, the overall structure of the mine protective net includes square grids, the mine protective net is of a two-layer structure, the upper-layer structure is made of steel bars, the lower-layer structure is made of steel wires, and the two layers are combined together through a point welding process. The mine protective net is simple and reasonable in structure and low in cost. Compared with a mine protective net purely made of steel wires, the rigidity is increased, and the protective level is increased. Compared with a mine protective net purely made of steel bars, the rigidity and tenacity are guaranteed, and the production cost is reduced.

Description

technical field [0001] The invention belongs to protective nets, in particular to a mine protective net. Background technique [0002] At present, mine disasters occur frequently in our country, so various armors are indispensable safety equipment for mining, and the mine protection net is the foundation of safety facilities. However, there are some problems with mine protection nets in our country. The material of some mine protection nets is Steel wire has toughness but insufficient rigidity, and there are hidden dangers in the protection of some large-scale falling objects, while other protective nets are made of steel bars, which can meet the requirements in toughness and rigidity, but the cost of use has increased significantly. Contents of the invention [0003] The purpose of the present invention is to provide a mine protection net to overcome the deficiencies in the prior art. [0004] The present invention is achieved in the following way: a mine protection net,...
