Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a magnetic suction type picking mechanism. Background Art

[0002] Underground mining in metal mines uses traditional rock drilling and blasting technology. The drilling rig drills holes in the excavation face and uses emulsion explosives for blasting. The rock structure will inevitably change after blasting. In order to avoid roof caving accidents and improve construction safety, pipe-seam anchor rods are used to fix the anchor net to the roof and side walls of the tunnel after blasting to complete the support of the roof and side walls of the tunnel.

[0003] In actual production, anchor support trolleys are often used to assist in the fixing process of the anchor net. The anchor support trolley picks up the anchor net by means of a mechanical arm and a clamp, and then spreads the anchor net to the area to be supported. A rock drill is used to drill the pipe-seam anchor eye. After the drilling is completed, a hammer is used to insert the anchor into the eye to fix the anchor net to the area to be supported.

[0004] Due to the limited space underground, the number of anchor support trolleys that can be used is limited, resulting in a limited number of clamps that can be used. In addition, the anchor net is a sheet-type mesh structure. When the clamp picks up the anchor net and lays it on the area to be supported, there is a problem of less support area, which makes the anchor net unable to be completely attached to the wall or difficult to lay, and requires manual assistance. Therefore, this application proposes a magnetic suction pickup mechanism that can increase the support area of ​​the anchor net. Utility Model Content

[0005] The main purpose of the utility model is to provide a magnetic suction type picking mechanism, aiming to solve the technical problem of less supporting area during the anchor net picking process.
