Laminated rubber bearing void pre-warning device

Abstract

The invention relates to a laminated rubber bearing void pre-warning device. In the past, a detector needs to reach a pier top through large equipment to perform naked-eye observation when detecting laminated rubber bearing void, and bearing void cannot be comprehensively discovered or pre-warned. A pressure sensor is arranged between the top surface of a laminated rubber bearing and an upper beam and serially connected with a warning light, the warning light is arranged on a pre-warning display, the pre-warning display is hung on the side of the beam, and the pressure sensor is a flaky pressure sensor. According to the laminated rubber bearing void pre-warning device, the detector can observe the force distribution state of the bearing and comprehensively discover bearing void without directly reaching the pier top for high-altitude operation or being affected by a bearing void position, possibility and development trend of bearing void can be pre-judged by daily and simply observing a pre-warning display system, a pre-warning function is achieved, accordingly, structural safety is ensured, and preventive measures are taken.

Description

technical field [0001] The invention relates to the maintenance and detection of bridge engineering, in particular to a pre-emption early warning device for plate rubber bearings. Background technique [0002] Plate-type rubber bearings are the main bearing form used in small and medium-span bridges in China. They are widely used in China and are used in a huge amount. With the operation of the bridge, the most typical disease of the plate rubber bearing is the hollow phenomenon of the bearing. At present, the maintenance and inspection methods for such supports require inspectors to use large-scale equipment to reach the top of the pier for visual observation, and the recent method of using outrigger rods with cameras and cameras to take pictures is also affected by the supports themselves and the supports. Due to the influence of block occlusion and other influences, the void phenomenon of the support cannot be found comprehensively. Neither the traditional method nor t...

Problems solved by technology

At present, the maintenance and inspection methods for such supports require inspectors to use large-scale equipment to reach the top of the pier for visual observation, and the recent method of using outrigger rods with cameras and cameras to take pictures is also affected by the supports themselves and the supports. block occlusion and other influences, it is impossible to fully discover the void phenomenon of the support

Neither the traditional method nor the existing equipment can directly detect the force state of the support, let alone give an early warning of the support being empty

[0003] The shortcomings of traditional detection methods and existing equipment are obvious: 1. It is impossible to judge the real force state of the support; 2. It is impossible to make predictions and early warnings for the support's void; 3. Large-scale hoisting equipment is required for on-site hoisting or erection 4. Inspection personnel need to work at heights, which is difficult and risky; 5. The efficiency of the entire inspection process is very low due to the need for large-scale hoisting equipment to hoist personnel to high altitudes to erect scaffolds; 6. Equipment rental The use of personnel and personnel makes the detection cost high; 7. The detection is easily blocked and there are missed detections
