Shock absorption and noise reduction device for highway bridge
The invention discloses a shock absorption and noise reduction device for a highway bridge in the technical field of highway bridge equipment. The device comprises a cross beam body, a rack, a supporting rod and an expanding mechanism. The racks are installed on the outer wall of the cross beam body, and the racks on the left side and the right side are arranged in a staggered mode. An expanding mechanism is mounted between the bottoms of the inner cavities of the two groups of cross beam bodies; a protection assembly is installed between the top end of the supporting rod and the outer wall of the bottom of the rack. Through cooperation of a sliding block, a sliding groove and a rotating shaft of the protection assembly, the supporting rod can rotate and slide below the rack, and the rack cannot provide leftward pushing force for the supporting rod in the process that the rack is pressed to move downwards. Therefore, the supporting rod is prevented from being bent easily due to fixed connection of the supporting rod and the rack, normal use of the opening mechanism is guaranteed, and the damping and noise reduction effects of the device are guaranteed.
本发明公开了公路桥梁设备技术领域的一种公路桥梁减震降噪装置，包括横梁本体、齿条、支撑杆与撑开机构，所述齿条安装在横梁本体的外壁上，且左右两侧齿条相互交错设置，两组横梁本体内腔底部之间安装有撑开机构，所述支撑杆顶端与齿条底部外壁之间安装有保护组件，装置中通过保护组件的滑块、滑槽与转轴配合，使支撑杆可以在齿条下方转动和滑动，使齿条在受压下移的过程中不会对支撑杆提供向左推力，避免支撑杆与齿条固定连接而导致支撑杆容易发生弯曲，保证撑开机构正常使用，保证装置的减震降噪效果。
