Force transmission device

Abstract

The invention provides a force transmission device which is formed by two semi-disc-shaped components. The two semi-disc-shaped components have the predetermined thickness, and can be combined together to form a cylinder. Grooves penetrating through the semi-disc-shaped components in the thickness direction are formed in the respective combination faces of the two semi-disc-shaped components. After the two semi-disc-shaped components are combined, the two grooves are combined to form a combination hole in smooth transition. The combination hole can be buckled to an installing hole of a tension sensor. In the installing process, the side wall, located in the installing hole, of the combination hole and the inner wall of the installing hole are closely matched in a face contacting mode. External grooves are formed in the respective outer arc parts of the two semi-disc-shaped components in the outer circumferential direction. When the two semi-disc-shaped components are combined to form the cylinder, the external grooves in the two semi-disc-shaped components are in smooth transition in the outer circumferential direction of the cylinder, the sections of the external grooves are of arc shapes, and when installed, steel wire ropes are installed in the external grooves in the mode of being matched with the external grooves.

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.
