Orientation- and pitching-adjustable laser amplitude instrument installation pedestal

Abstract

The invention discloses an orientation- and pitching-adjustable laser amplitude instrument installation pedestal, including a bearing pedestal, a support rod, a lifting adjusting rod and a fixed device. The bearing pedestal is arranged on the ground, one end of the support rod is movably connected with the bearing pedestal, the support rod is vertical to the bearing pedestal, side faces of the support rod are provided with symmetrical sliding grooves along an axis direction, two sides of the sliding grooves are provided with connecting pieces respectively, matched screws are arranged in the connecting pieces, the connecting pieces are connected through bolts, the bottom of the lifting adjusting rod is connected with the support rod through the sliding grooves of the support rod, the top ofthe lifting adjusting rod is connected with the fixed device, one end of the support rod is provided with an angle dial, a pointer is arranged on the angle dial, the tip of the pointer corresponds tothe scale on the angle dial, and the tail of the pointer is connected with the support rod. 360-degree adjustment of the laser amplitude instrument in a horizontal direction is realized through mechanization, and the angle of adjustment of the laser amplitude instrument is clearly and directly obtained according to the scale on the angle dial.

Description

technical field [0001] The invention relates to bridge health monitoring, in particular to a laser amplitude meter installation base with adjustable azimuth and pitch. Background technique [0002] As an integral part of the transportation system, bridges have played an important role in the development and evolution of human civilization. With the development of modern technology and the continuous growth of transportation demand, more and more large bridges (such as sea-crossing bridges, long-span bridges, etc.) appear in people's field of vision. It has important strategic significance in terms of transportation, military and social life. [0003] However, during the construction and use of the bridge, due to the erosion of the environment, harmful substances, vehicles, wind, earthquakes, fatigue, human factors, etc., as well as the continuous degradation of the properties of the materials themselves, the structural parts are far from reaching the design life. Different...

Problems solved by technology

[0009] The invention solves the need to adjust the installation position when changing the monitoring point of the laser amplitude meter in the process of using the bridge health monitoring system in the prior art, which increases the workload of relevant personnel and affects the bridge health monitoring system at the same time. To solve the problem of operation, provide a laser amplitude meter installation base with adjustable azimuth and pitch, which can realize the 360-degree rotation of the laser amplitude meter in the horizontal direction during application, which is convenient for the laser amplitude meter to collect data at different points according to needs, and at the same time can Realize the adjustment of a certain position in the vertical direction, which effectively solves the adjustment of the position and height of the laser amplitude meter in the vertical direction, so that the measurement range of the laser amplitude meter has been expanded to a certain extent
