Problems solved by technology

[0003] But for now, there is no equipment that can monitor the health of the bearing, or a bearing with a pressure monitoring function. Some people have tried to use sensors to detect the force of the bearing, but ordinary sensors cannot be placed In the support, even if it can be placed in the support, it will affect the force of the support and cause adverse effects

Embodiment Construction

[0028] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] see in conjunction Figure 1-Figure 2 Shown is Embodiment 1 of the support of the present invention.

[0030] The support in the present embodiment includes: a top support plate 21, a bottom support plate 22, a bottom support plate 22 and a ball-shaped steel plate slidably fastened between the top support plate 21 and the bottom support plate 22. The plate 11 and the bottom support plate 22 are equipped with a pressure monitoring structure on one side facing the spherical rigid plate 11 . The pressure monitoring structure includes a stainless steel diaphragm 31 (such as figure 2 shown), and the alloy resistor 32 installed on the stainless steel diaphragm 31, the alloy resistor 32 is integrated with the stainless steel diaphragm 31 through molecular bonds to form the alloy thin film strain unit 3 for inductive Wheatstone bridge.

Abstract

The invention discloses a pressure monitoring structure for a support. The pressure monitoring structure comprises a stainless steel membrane and an alloy resistor. The stainless steel membrane is embedded in a mount of the support to sense the external load. The alloy resistor is mounted on the stainless steel membrane and integrated with the same through molecular links, and an alloy film strain unit is formed to sense a Wheatstone bridge. To be specific, the external load acts on the support to cause deformation of the alloy film strain unit, and the alloy film strain unit generates a voltage signal monitoring vertical pressure of the support. The invention further discloses the support. The support and the pressure monitoring structure thereof have the advantages that stress on the support is monitored in the real-time manner, and health condition of the support is judged; fatigue-resistant performance is excellent, and stability is high; size is small, and influence to the mechanical property of the support is small.

Description

technical field [0001] The invention relates to the field of supports, in particular to a support capable of monitoring health conditions in real time and having a self-diagnosis function. Background technique [0002] Judging from the damage of bridges in the past, most of the damage occurred at the bridge support. The long-term stability of the bridge is of great significance to the overall safety of the bridge. [0003] But for now, there is no equipment that can monitor the health of the bearing, or a bearing with a pressure monitoring function. Some people have tried to use sensors to detect the force of the bearing, but ordinary sensors cannot be placed In the support, even if it can be placed in the support, it will affect the force of the support and cause adverse effects. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a support that can monitor the force of the support in real time, thereby judging th...
