Description
Technical Field
The utility model relates to a colliery is the detection area of anchor rope anchor power in the pit, specifically is an anchor rope anchor power detection device.
Background
With the continuous improvement of the supporting technology of the coal mine roadway roof, supporting materials are continuously updated. At present, the materials such as anchor cables, anchor rods and the like are widely applied to the coal mine roadway support, and the support technology of the anchor cables matched with the anchor rods and hung with steel beams and metal nets is better applied to the coal mine production. The method is characterized in that an anchor cable and an anchor rod are used for supporting in time in a tunneling and stoping crossheading, the using amount of anchor cable supporting materials is continuously increased, due to the lack of effective anchor cable anchoring quality detection and monitoring means and devices, the anchoring quality of an anchor cable supporting roadway is often not over-limited, phenomena of insufficient anchoring strength and the like sometimes occur, the annual repair amount of the roadway is more than 15%, the roadway needing to be repaired is about thousands of meters due to the fact that the anchor cable supporting fails every year, and the supporting cost is increased. Therefore, the anchoring quality detection is necessary to detect the construction quality of the anchor cable. Aiming at the condition that the number of anchor cable supports is increased, and the using amounts of the anchor cables, the lock and the steel base plate are also increased continuously, how to reduce the consumption cost of anchor cable materials is realized, how to timely detect the full utilization of the lock and the steel base plate of the anchor cables and the anchoring force of the construction quality of the anchor cables in a time-saving and labor-saving manner becomes a big problem facing people, and if the anchoring force of the anchor cables can be timely detected, the construction quality of the anchor cables can be greatly improved. Therefore, the anchoring force of the anchor cable is tested by adopting a pneumatic anchor cable tensioning device. However, in production practice, such a device has been found to suffer from a number of disadvantages: the pressure of the anchor rod can not meet the requirement of an anchoring force test, and the anchor rod is slow in speed, insufficient in wind pressure, inconvenient to operate, time-consuming, labor-consuming, incapable of exerting due efficiency and convenient to eliminate.
Because of lacking effective anchor rope anchoring quality detection, means and device of monitoring, anchor rope supports the tunnel and often appears the anchoring quality and does not pass, can appear sometimes that anchoring strength is not enough phenomenons such as, has not used the use tool of inspection anchor rope anchoring power for a long time, use pneumatics or manual tensioning machine utensil jack to extrude experimental anchor rope anchoring power by force always, sometimes damage its tool to lock, still must mend again and beat the anchor rope, extravagant supporting material, and speed is slow, also can not reach the requirement of inspection anchor rope anchoring power, and the operating rate is very low. Therefore, it is necessary and significant to research a tool for checking the anchorage force of the anchor cable.
Disclosure of Invention
The utility model discloses a solve the above-mentioned multiple problem that current anchor rope anchor power detected the existence, provide an anchor rope anchor power detection device.
