Device for roadbed strength reinforcement and ramp collision prevention

Abstract

The invention relates to a device for roadbed strength reinforcement and ramp collision prevention. A supporting frame is hinged to the bottom end of the surface of a protection rod, the bottom end of the protection rod is located in the supporting frame, a connecting frame is hinged to the bottom end of a T-shaped rod at the right end of a connecting rod on the right side of the protection rod, a hinge rod is hinged to the bottom of the connecting frame, and the rear side, slidably connected with a sliding sleeve, of the surface of the hinge rod is rotationally sleeved with a left pulley; the inner part of a bolted support at the right side in the supporting frame is sleeved with a right pulley in a rotating mode, the left half part of a left bolted steel wire rope of the support is of a C-shaped structure and is in sliding connection with the left side of the left pulley, the right half part of the steel wire rope is of a U-shaped structure and is in sliding connection with the right side of the right pulley, one end of the steel wire rope far from the support is bolted with a buffer mechanism at the bottom of the transmission mechanism, and the bottom end of the surface of the protection rod is hinged with an auxiliary mechanism. The device solves the problems that an existing ramp reinforcement and collision prevention device for road administration is small in buffering range and poor in collision prevention effect, a guardrail is prone to shaking, stability is poor, and a roadbed is prone to being damaged.

Description

technical field [0001] The invention belongs to the technical field of engineering, and relates to a device for roadbed strength reinforcement and ramp anti-collision. Background technique [0002] In the process of road construction, it is often necessary to set up reinforcement and placement structures. For example, the invention patent with the application number CN202011151423.5 discloses a ramp reinforcement anti-collision device for road administration. Compression resistance can effectively reduce the road subsidence caused by heavy loads and avoid vehicle rollover caused by road subsidence; the embedded cross bar suppresses the insertion rod, and the main frame rod is positioned through the insertion rod. When the guardrail structure is impacted, the main The frame rod can rotate along the pin shaft, overcome the elastic force of the first spring while rotating, use the first spring to increase the impact resistance of the main frame rod, and compress the first sprin...
