Core anti-corrosion anchor cable anchorage for mining

Abstract

The invention discloses a core anti-corrosion anchor cable anchorage for mining, belongs to the technical field of anchor cable anchorages, and is applied to the anti-corrosion of the inner part and steel strand of the anchorage at the installation position of the anchor cable anchorage; the anchorage comprises a clamping piece clamping on the outer wall of the steel strand and an anchor ring sleeving on the clamping piece; the device is characterized in that the upper end face and / or lower end face of the anchor ring are provided with a sealing element for preventing corrosion materials fromentering the gap between the outer wall of the steel strand and the inner wall of the anchor ring. By using the technical scheme, the core anti-corrosion anchor cable anchorage device utilizes the sealing element to prevent the corrosion materials from entering the gap between the outer wall of the steel strand and the inner wall of the anchor ring, thereby avoiding the defect that the connectingpart of the anchorage is rusted; meanwhile, because the sealing element comprises a sealing brush, anti-corrosion grease and a protective sleeve, which are a triple sealing structure, the sealing effect is further ensured. Experiments show that no rust condition is discovered when the device is placed in a salt fog test environment for 100 hours.

Description

technical field [0001] The invention belongs to the technical field of anchor cables and anchors, and in particular relates to an anti-corrosion anchor cable and anchor for mining cores. Background technique [0002] At present, cable anchors are commonly used in coal mine support. The disadvantage of traditional cable anchors is that due to the relatively humid environment of coal mine roadways, when cable anchors are used in coal mine roadways in humid and corrosive environments, due to air or A large amount of corrosive substances and water contained in the rock strata enter the interior of the anchorage, which leads to serious corrosion inside the anchorage, failure of the anchorage, and serious hidden dangers to the roadway support. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a mining core anti-corrosion anchor cable anchorage, which can isolate the anchorage from the outside world and prevent external corr...
