Portable detection device for flatness of asphalt pavement
The invention belongs to the technical field of road construction detection, and discloses a portable detection device for the flatness of an asphalt pavement. The device comprises a device main body, supporting columns are fixedly arranged at the four corners of the bottom end of the device main body, a plurality of through grooves are formed in the middle of the device main body, a movable rod is movably arranged in each through groove, movable cavities are formed in the two sides of each through groove, limiting rings located in the movable cavities are integrally arranged on the movable rods, reset springs located in the movable cavities are fixedly arranged at the top ends of the limiting rings, fixing frames are fixedly arranged on the two sides of the top end of each through groove, a movable rope is connected between the fixing frames on the two sides, and a cavity is formed in the fixing frame on one side, a torsion spring rotating shaft is installed at the middle of the cavity,one end of each movable rope is fixedly connected with the torsion spring rotating shaft, a through hole is formed in one side of the cavity, a rotating wheel is fixedly installed at the end, extending out of the through hole, of the torsion spring rotating shaft, and a recording pen is fixedly arranged on the rotating wheel. The device can improve the detection efficiency, does not need manual recording, and is more convenient to use.
本发明涉及道路施工检测技术领域，且公开了一种沥青路面平整度便携式检测装置，包括装置主体，装置主体的底端四角处均固定设置有支撑柱，装置主体的中部开设有若干个通槽，每个通槽内均活动设置有活动杆，每个通槽的两侧均开设有活动腔，活动杆上一体设置有位于活动腔内的限位环，限位环的顶端固定设置有位于活动腔内的回复弹簧，每个通槽顶端的两侧均固定设置有固定架，两侧固定架之间连接有活动绳，一侧固定架的内部开设有腔室，腔室的中部安装扭簧转轴，活动绳的一端与扭簧转轴固定连接，腔室的一侧开设有通孔，扭簧转轴伸出通孔的一端固定安装转轮，转轮上固定设置记录笔。该发明能够提高检测的效率，无需人工进行记录，使用更加方便。
