force transmission device

Abstract

The force transmission device of the present invention is composed of two semi-disc-shaped members having a predetermined thickness and capable of being combined to form a cylinder, and a semi-circular plate penetrating through the thickness direction is formed on the joint surfaces of the two semi-disc-shaped members. The groove of the disc-shaped component, after the combination of the two semi-disc-shaped components, the two grooves are combined into a combination hole with a smooth transition, the combination hole can be fastened to the installation hole of the tension sensor, and the combination hole is located at the installation The side wall of the part in the hole is closely matched with the inner wall of the mounting hole in a surface contact manner, and an external groove is formed on the respective outer arc parts of the two semi-disc-shaped members in a manner along the outer circumference. When two semi-disc-shaped components are combined to form a cylinder, the external grooves on the two semi-disc-shaped components in the outer circumferential direction of the cylinder transition smoothly, and the section of the external groove is arc-shaped. When installing the wire rope , the wire rope is placed in the external groove in a manner that cooperates with the external groove.

Description

technical field [0001] The invention relates to a force transmission device, in particular to a force transmission device which can be used between a protective net wire rope and a tension sensor. Background technique [0002] In the protection of dangerous rocks and falling rocks, flexible passive protective nets have begun to be widely used. If the flexible protective net is impacted by falling rocks exceeding its protection energy level, various forms of failure such as the failure of the protective net or the destruction of the support column of the protective net will often occur. . Therefore, the failure monitoring of the protective net is particularly important. At present, the commonly used monitoring method is to install force sensors on the lower support rope or the anchor rope. [0003] The connection between the tension sensor and the wire rope of the protective net has two connection modes: attachment type and string-in type. The serial connection method has ...

AI Technical Summary

Problems solved by technology

[0004] (1) The processing precision of the shackle is not high, and the connection with the sensor is not tight, and the force transmission is the coexistence of tension and bending;

[0005] (2) The wire rope is subjected to torsional load during construction, and the shackle cannot offset it

[0006] To sum up, the force sensor cannot truly reflect the force of the wire rope of the protective net, which will cause false alarms or missed alarms.
