Beckman beam with automatic reading function for measuring rebound deflection of road surface

A Beckman beam with an automatic reading function for measuring rebound deflection of a road surface comprises a reading device and a Beckman beam body, and the reading device is movably arranged at one end, provided with a measuring table, of the Beckman beam body; the reading device is provided with a laser displacement sensor which is positioned at the upper part of the measuring table; when the Beckman beam with the automatic reading function for measuring the rebound deflection of the road surface works, the height of the laser displacement sensor does not need to be manually adjusted aiming at each measuring point, original data and changed data of the same measuring point do not need to be manually read and recorded, the displacement value of the measuring table only needs to be automatically read and recorded through the laser displacement sensor, and the measurement accuracy is greatly improved. Therefore, an operator does not need to squat on the ground for operation for a long time, the labor inten
