Problems solved by technology

The traditional pressure pillow adopts the vibrating wire mechanical principle. The stress gauge is not sensitive, the reading value error is large, and it cannot collect and store functions in real time. When the bolt is under heavy force, it cannot alarm and prompt, which cannot meet the safety needs of the mine.

Abstract

The invention discloses an anchor pole cable intelligent early warning stressometer including a sensor body (1) which is arranged at the bottom of an anchor pole (2), the sensor body (1) is vertically provided with two opposite drilling holes, strain gauges (101) matched with the drilling holes are inserted into the two drilling holes, one side of the sensor body (1) is provided with a long rod (102), a sensor circuit board is arranged in the long rod (102), the sensor circuit board is connected with the strain gauges (101) via signal lines, an interface is arranged outside the sensor circuit board and is connected with a modem (4) via a signal line (3), the modem (4) is connected with a collector (5) in a wired or wireless communication manner, the collector (5) is connected with a ground computer (6), and an audible and visual alarm (401) is integrated in the modem (4). The stressometer has the functions of real-time acquisition and storage, the anchor rod can give alarm prompt when being subjected to large force, and the safety need of a mine is met.

Description

technical field [0001] The invention relates to the technical field of force monitoring of bolts and cables in roadways supported by anchor nets, in particular to an intelligent early warning stress gauge for bolts and cables. Background technique [0002] Coal mine anchor net support roadway is widely used. In the process of anchor rod and anchor cable support, the anchoring effect of anchor rod and anchor cable on the surrounding rock makes the surrounding rock of the roadway stable, reduces damage, and ensures safe production in coal mines. Since the force of the bolt and cable cannot be monitored during the anchoring process of the anchor and cable in the surrounding rock, in order to understand the change of the force of the bolt and cable and to grasp the force of the bolt and cable in time, according to the It is an urgent problem for coal mines to take corresponding support measures for the roadway according to the force of the rod and anchor cable to prevent the occ...
