Description

Technical Field

[0001] The utility model relates to the technical field of mining equipment, in particular to a mining anchor cable dynamometer. Background Art

[0002] The anchor tension meter is a testing tool for measuring the anchoring force of anchor rods on site. It has the function of loading anchor rods, steel bars and other anchor bodies to achieve the anchoring force. The anchor tension meter is suitable for on-site testing of the anchoring force of anchor rods, steel bars and other anchor bodies. It is an on-site testing instrument for various quality inspection units. The anchor tension meter has the characteristics of small size, light weight, easy to carry, simple operation and safety. It is widely used in various tunnel operations such as coal, national defense, slope, and transportation.

[0003] When the existing anchor cable dynamometer is used in coal mines, it is particularly important to detect the stability of the anchor rod in such a dangerous environment as coal mines, which is related to the safety of workers and the quality of construction. After being fixed, many existing mining anchor rods are set on inclined or straight surfaces. When the mining anchor cable dynamometer is used for testing, the gravity of the pull rod part itself is borne on the anchor rod and other tools, so that the anchor rod is not only affected by the force from the dynamometer, but also by gravity. It is not stable enough and has defects that affect the detection effect. In this regard, we design a mining anchor cable dynamometer. Utility Model Content
