Rotating-shaft-free calibration device capable of being quickly disassembled for laser pavement structure depth instrument

Abstract

The invention discloses a rotating-shaft-free calibration device capable of being quickly disassembled for a laser pavement structure depth instrument, and belongs to the field of pavement structure depth tests. A spindle motor and a fixing plate are installed on an equipment shell. The device further comprises two synchronous blocks, a sliding way and two synchronous strips, a spring is arranged in the sliding way and connected with the synchronous blocks to move upwards, the synchronous blocks are connected with the synchronous strips, and the two synchronous strips are connected to a turntable, therefore, the turntable is effectively clamped by a turntable clamping jaw; a rotating wheel at the top of the turntable clamping jaw is in contact with the edge of the turntable through the tightening force of the turntable clamping jaw; the spindle motor is connected with the synchronizing wheel through a belt to rotate, and the synchronizing wheel penetrates through the fixing plate through a bearing to be connected with a movable rubber wheel; a groove is formed in the side surface of the rubber wheel; the turntable is clamped into the groove of the rubber wheel; the spindle motor drives the synchronizing wheel to rotate through a belt, and the synchronizing wheel penetrates through the fixing plate through a bearing to drive the rubber wheel to rotate. The device ensures reliable grasping when the turntable rotates at a high speed. The design that the turntable is driven to move through friction of the rubber wheel reduces the complexity of disassembly of traditional equipment, and the working efficiency is improved.

Description

technical field [0001] The device belongs to the field of pavement structure depth test. Background technique [0002] The pavement structure depth refers to the average depth of the uneven opening pores on a certain area of ​​the road surface. It is mainly used to evaluate the macroscopic roughness, drainage performance and skid resistance of the pavement surface, and is closely related to the durability of the pavement and driving safety. [0003] At present, there are two main methods for pavement structure depth testing: sand laying method and laser structure depth measurement method. [0004] The sand laying method spreads a known volume of standard sand on the measured area of ​​the road surface to be tested, and then divides the volume of the standard sand by the area paved on the test road surface to obtain the average depth as the pavement construction depth . This test method yields an average depth value within the paved area. [0005] The laser structure depth...

Problems solved by technology

[0011] It is inconvenient to disassemble the turntable of the existing equipment. After each measurement, the operator needs to manually remove the turntable. For the scene where the turntable needs to be disassembled many times, the efficiency of the existing equipment is low
