Honesty management of mining anchor cable tensioning machine tools

Anchor cable tensioning equipment usage

Anchor cable tensioning equipment consists of prestressed tensioning jacks, quick connectors with one-way valves, high-pressure oil pipes, manual oil pumps (pneumatic oil pumps, electric oil pumps), etc. It is mainly used to tension anchor cables and install anchors when supporting anchor cables in coal mine tunnels. It can also be used to tension prestressed steel strands in bridges, tunnels, highways, etc.

Introduction to anchor cable tensioning equipment

When the hydraulic pump station starts working, the oil is sucked into the high and low pressure oil suction check valves by the plunger, and pressed into the working tensioning jack through the high and low pressure oil discharge check valves. When the pressure rises to 1.5MPa, the low pressure relief valve opens and the low pressure oil overflows back to the tank; on the above basis, the high pressure plunger continues to work and the pressure gradually increases.Promote the tensioning jack to tension the anchor cable.Then, turn the reversing valve to realize the reverse movement of the piston and withdraw the anchor.When the pressure exceeds 63MPa, the high-pressure valve opens, and the high-pressure oil overflows from the high-pressure valve back to the tank, and the pressure is always maintained at 63MPa.

Characteristics of anchor cable tensioning equipment

1. The tensioning jack has a built-in tool anchor, which not only realizes automatic anchoring and automatic anchor withdrawal, but also ensures operational safety and improves work efficiency.

2. The overall structure is reasonable, the performance is superior, the operation is simple, and it is safe to use.
