Description

Technical Field

[0001] The utility model relates to the technical field of woven cloth, in particular to a polyester fiber flexible net amplification connection structure. Background Art

[0002] The roof management of the last mining face of the fully-mechanized mining face in a coal mine and the roof management during the withdrawal period are important links in the safety work of coal mines. The traditional withdrawal method adopts the laying of metal mesh. During the expansion of the withdrawal channel, each cycle requires operators to manually transport, hang and connect the mesh. Operators frequently enter the coal wall side conveyor, which has high labor intensity and poses certain safety hazards.

[0003] The high-strength polyester fiber flexible net adopts a one-time hanging net roof laying process instead of the metal mesh laying and networking process, which simplifies the finishing process, effectively reduces the risk, and eliminates the dangerous source of frequent hanging nets and networking. However, the maximum width of the high-strength polyester fiber flexible net is 6 meters. The working environment of the comprehensive mining face of the coal mine is complex and changeable. The conditions of the roof at the end of the comprehensive mining face and the roof during the withdrawal period are different, and the strength, length and width of the flexible net are different. In order to meet the needs of the project, it is often necessary to connect 2, 3 or more pieces of high-strength polyester fiber flexible nets on the ground before use. Generally, the edges of two adjacent flexible nets are overlapped and connected with ropes at about 50 cm. The maximum strength of the connection is only 20% of the strength of the body.

[0004] Therefore, the strength of the connection between the two high-strength polyester fiber flexible nets is a weak link, which is difficult to reach 50% of the main body strength. During use, it is easy to cause problems such as pulling of the net, tearing, and leakage of gangue from the roof, and the safety of coal miners cannot be guaranteed. Utility Model Content
