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

[0029] Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] see in conjunction Figure 1-Figure 2 Shown is Embodiment 1 of the basin rubber bearing of the present invention.

[0031] The pot-type rubber bearing in this embodiment includes: a top support plate 21, a steel basin 23, a steel basin 23, and a rubber plate 12 that can be slidably fastened between the top support plate 21 and the steel basin 23, and the steel basin The side edge of 23 is higher than the top surface 121 of the rubber plate 12; the contact part between the rubber plate 12 and the steel basin 23 is provided with a seal 13.

[0032] A pressure monitoring structure is installed on the side of the steel basin 23 facing the rubber plate 12 . 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...

Abstract

The invention discloses a pot type rubber support. The pot type rubber support comprises a top support plate, a steel pot and a rubber plate, wherein the rubber plate can be fastened between the top support plate and the steel pot; a side edge of the steel pot is higher than the top surface of the rubber plate; a sealing piece is arranged on a portion, which is in contact with the steel pot, of the rubber plate; a stainless steel diaphragm is inserted in one side, which faces the rubber plate, of the steel pot; an alloy resistor is assembled on the stainless steel diaphragm and is integrally connected with the stainless steel diaphragm through molecular bonds, so that an alloy film strain unit, which is used for inducing the vertical pressure of a support, of a Wheatstone bridge is formed; and an external load acts on the pot type rubber support, and the alloy film strain unit deforms and generates a voltage signal for monitoring the vertical pressure of the pot type rubber support. The stress condition of the pot type rubber support can be monitored in real time, so that the health condition of the pot type rubber support can be judged; the pot type rubber support is high in fatigue resistance, high in stability and small in size; and influence on the mechanical property of the pot type rubber support is low.

Description

technical field [0001] The invention relates to the field of bearings, in particular to a pot-type rubber bearing that can monitor health conditions in real time and has 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 basin-type rubber bearing, which can monitor the force of the basin-type r...
