Problems solved by technology

[0004] Chinese patent CN203452813U discloses a scheme for judging the axial force by observing the displacement of the high-strength spring, but because the displacement is too small, it is very difficult to judge the axial force of the bolt directly by visually observing the amount of deformation

Abstract

The invention discloses a device and method for monitoring unidirectional force and belongs to the field of sensors. The device is constituted by a display device and a load balancing mechanism. The device comprises an upper housing and a lower housing, wherein a space formed by the upper housing and the lower housing in a snap-fit mode is provided with a supporting body and the outside of the supporting body is provided with a display device; uniform pressure produced by the load balancing mechanism is converted to different colors by the display device; the force condition is judged through observing different color of the display device. The device need no maintenance or management or inspection by specially-assigned persons, anyone can be the safety supervisor. The device is of great importance to construction quality management and safety production of anchor rod support engineering. By use of the invention, top plates are effectively prevented from falling down and coal mine safety production is guaranteed.

Description

technical field [0001] The invention relates to a unidirectional force monitoring device and a monitoring method, belonging to the field of sensors. Background technique [0002] There are many occasions in engineering that need to monitor or display unidirectional force, such as bolt fastening force in important occasions, anchor rod or anchor cable axial force in geotechnical engineering. It is very important to display these forces timely and accurately for the safety of engineering facilities. There are two types of traditional unidirectional force monitoring devices. One uses a power source, such as a strain gauge type, which uses the strain of the anchor rod to detect the stress of the anchor rod. However, due to the need for a power source, the safety management is complicated. The other type does not require power supply, there are hydraulic type and pressure sensitive paper type. The hydraulic type is composed of a hydraulic pressure box and a pressure gauge. The l...
