Problems solved by technology

[0004] The invention effectively solves the situation that the exposed steel strands are relatively long and the coal mine roadway is relatively low, and it can also effectively solve the situation that the anchorage slips due to the small initial anchoring force of the anchorage, and has a secondary effect on the anchorage. The role of pulling

Abstract

The invention relates to a mining anchor cable end shaping device. The mining anchor cable end shaping device is characterized in that a base (6) is arranged on a headstock (10); a strand-breaking press head is arranged on the base (6), and is composed of an installation body (5), a clamping sleeve (4), a pressing sleeve (3), an elastic ring (2) and a fixing pin (12); the installation body (5) is fixedly arranged on the base (6); the clamping sleeve (4) is arranged in the installation body (5); the pressing sleeve (3) is arranged on the clamping sleeve (4); the elastic ring (2) is arranged on the pressing sleeve (3); a fixing pin groove (13) is formed in the clamping sleeve (4); the clamping sleeve (4) and the installation body (5) are fixed together through the fixing pin (12); an arc-shaped groove (15) is formed in an inner ring (14) of the clamping sleeve (4). By adopting the mining anchor cable end shaping device, the problem of the relatively long exposed steel strand is solved, the condition that the primary anchorage force of an anchor is small, thus the anchor slides downwards is avoided, and the roof caving accidents are reduced.

Description

technical field [0001] The invention belongs to the technical field of mining machinery equipment, in particular to a mine anchor cable end shaping device. Background technique [0002] Mine cable anchors have been widely used in coal mine roadways in recent years, and are now gradually developing in the direction of large specifications. The anchor cables are composed of anchor cable trays and steel strands, so the steel strands are getting thicker and thicker. In the limited space in the coal mine roadway, the exposed steel strands are very long, which is easy to scratch and bruise people, posing safety hazards, so the exposed steel strands that are too long must be cut off. Hydraulic shears can effectively cut exposed steel strands that are too long, but with the increase of specifications, the weight of hydraulic shears is getting heavier and heavier. Hydraulic shears that cut Φ28.6 steel strands require at least two people to lift them , The labor intensity of workers ...
