Embodiment Construction
[0009] An anchor net connection hook, according to the distance between the two anchor nets, the anchor net connection hooks of different lengths are inserted between the steel wire mesh between the two anchor nets, and the inner curved hook 1 at the tail is hooked Steel wire; when the roof is suddenly pressed or deformed, it will destroy the anchor net support. The wave structure can enhance the support strength generated by the two anchor nets. The deformation process of the wave section 3 after compression can delay the deformation process of the roof , the roof finally changes from a load to a structure, and at the same time it can continue to play the supporting role of the anchor net, providing time for subsequent repair work.

Abstract
The invention discloses a connecting hook for anchor webs, relates to an anchor web connecting hook used in underground coal mines, and belongs to the field of mining machinery. A reinforcing steel bar with the diameter being 0.5 cm is bent into a wave shape through a machine tool. The arc lengths of wave sections are as all equal to 5 cm. The radian of each wave section is 2 / 3 pi. The connecting hook for the anchor webs is simple and convenient to install, and not limited to work environments; the manufacturing process is simple and has high promotion value; the supporting effect is good after the connecting hook is used; and the safety is remarkably improved.
Description
technical field [0001] The invention relates to an anchor-net connection hook used underground in coal mines, belonging to the field of mining machinery. Background technique [0002] In coal mines, when connecting two adjacent anchor nets, the current method is to use iron wires to connect and then tighten and fix. This connection method has poor safety effect, and it is very inconvenient when working on the top. It is time-consuming and laborious, and needs to be improved. Contents of the invention [0003] The purpose of the present invention is to provide a kind of anchor net connecting hook which can be directly inserted between two anchor nets and can connect and fix two anchor nets without twisting. [0004] The technical solution adopted by the present invention to solve its technical problems is: a kind of anchor net connection hook, which is characterized in that a steel bar with a diameter of 0.5cm is bent into a wave shape by a machine tool, and the arc length ...
