Highway bridge guardrail capable of achieving rapid butt joint
The invention relates to the technical field of guardrails, and discloses a highway bridge guardrail capable of achieving rapid butt joint, the highway bridge guardrail comprises a first guardrail and a second guardrail, the first guardrail comprises two sets of supporting frames, the side walls of the two sets of supporting frames are fixedly connected with a connecting frame, a plurality of sets of supports are arranged in the connecting frame, and a fixing device is arranged in the first guardrail; the fixing device comprises a connecting block, a connecting groove, a device groove, a supporting spring, a sliding plate, a first limiting block, a first limiting groove, an extrusion spring, a moving rod and a limiting plate, the first limiting block can be pressed inwards to enter the device groove, and then the connecting block is connected with the interior of the connecting groove; at the moment, the first limiting block is extruded by the inner wall of the connecting groove so as to be in an extruded state all the time, and after the first limiting block moves to the first limiting groove, the first limiting block is not extruded any more and restores under the elastic force of the supporting spring so as to clamp the first limiting groove, so that the first limiting groove and the first limiting block are fixedly connected.
本发明涉及护栏技术领域，且公开了一种可快速对接的公路桥梁用护栏，包括第一护栏和第二护栏，第一护栏包括两组支撑架，两组支撑架侧壁固定连接有连接架，连接架内部设置有若干组支架，第一护栏内部设置有固定装置，固定装置包括：连接块、连接槽、装置槽、支撑弹簧、滑动板、第一限位块、第一限位槽、挤压弹簧、移动杆、限位板，可以向内按压第一限位块使其进入装置槽内部，然后将连接块和连接槽内部进行连接，此时第一限位块受到连接槽内壁的挤压从而一直处于被挤压状态，当第一限位块移动至第一限位槽后，第一限位块不再受到挤压并且在支撑弹簧的弹性力下进行复原从而卡住第一限位槽，使二者进行固定连接。
