Tensile damping supporting rod

Abstract

The invention discloses a tensile damping supporting rod. The tensile damping supporting rod comprises a first pipe fitting, a second pipe fitting and damping rod pieces; one end of the first pipe fitting is axially and slidably inserted into a pipe cavity in one end of the second pipe fitting; hinge bodies are arranged at the other ends of the first pipe fitting and the second pipe fitting correspondingly; the damping rod pieces are arranged in the pipe cavity of the first pipe fitting and a pipe cavity of the second pipe fitting, and the two ends of damping rod pieces are fixedly connected with one hinge body. The tensile damping supporting rod improves the anti-collision protection capacity of a height limiting frame while supporting the height limiting frame, and is simple and compactin structure and convenient for construction.

Description

technical field [0001] The invention relates to the technical field of support for traffic height-limiting facilities, in particular to a tensile damping support rod. Background technique [0002] With the continuous development of bridge technology and the transportation industry, bridges have been erected above many waterways. When ships pass through bridge openings, due to uncertain factors such as tides and waves, it is inevitable that the top of the ship will be higher than the bridge opening. This in turn caused the ship to collide with the bridge. At present, the anti-collision protection of bridges in various countries is mostly concentrated on the anti-collision of bridge pier and fender technology, and the anti-collision protection of bridge frame is rarely involved. Some bridges have protected the bridge frame, but it is basically based on the height limit of vehicles on land. As a measure, a height-limiting device such as a vehicle height limiter is installed un...

Problems solved by technology

Tracing it to its cause, mainly because the tonnage of freight ships is generally larger, similar devices that can play a better effect of limiting height and anti-collision on vehicles with smaller tonnages cannot also play a better role on ships; at the same time, because The environment is more complicated than that on land, and the adaptability of direct transplantation of land-based height-limiting devices is poor, and installation and maintenance are also inconvenient, so it is impossible to truly effectively limit the height of ships and avoid collisions
