Detachable penetration prevention and protection device for heavy-haul freight car based on non-Newtonian fluid

Abstract

The invention discloses a detachable penetration prevention and protection device for a heavy-haul freight car based on non-Newtonian fluid. The detachable penetration prevention and protection deviceincludes anti-collision belts and a plurality of connecting pieces. The anti-collision belts each includes a metal shell, a buffer layer, a rubber bag and non-Newtonian fluid filler; the buffer layers and the rubber bags are arranged in cavities of the metal shells, and the buffer layers are placed between the rubber bags and the metal shells; the rubber bags are closed bags with fluid inlets andfluid outlets separately formed in both ends, the fluid inlets and the fluid outlets lead to the outside of the metal shells, and the rubber bags are filled with the non-Newtonian fluid filler; and the multiple connecting pieces with reserved holes are arranged on two end parts of the anti-collision belts, and the anti-collision belts are fixedly installed on the front side surface and the rear side surface of a truck compartment through high-strength bolts arranged at the reserved holes. The detachable penetration prevention and protection device has the beneficial effects that the non-Newtonian fluid can be replaced at any time as needed, the detachable penetration prevention and protection device is simple and fast, easy to operate and free to install and disassemble, and under the premise of fully guaranteeing penetration prevention and protection functions, the detachable penetration prevention and protection device fully meets a green construction theory of resource conservationand environment friendliness to the greatest extent.

Description

technical field [0001] The invention relates to a detachable anti-stab protection device for heavy-duty trucks based on non-Newtonian fluid, and relates to the technical field of transportation equipment. Background technique [0002] With the continuous development of science and technology and social economy, my country's high-rise buildings, rail transit, deep foundation pit excavation and other infrastructure construction have been vigorously developed. Infrastructure construction inevitably requires a large amount of building materials such as steel bars, steel pipes, and steel bars. These materials are usually processed by factories and then transported to the project site by heavy-duty trucks. Due to the small friction coefficient between steel bars and other building materials, when a heavy-duty truck suddenly brakes or starts, the steel bars and other building materials will move forward or backward relative to the truck, and in severe cases, the cab will be pierced...

AI Technical Summary

Problems solved by technology

Due to the small friction coefficient between steel bars and other building materials, when a heavy-duty truck suddenly brakes or starts, the steel bars and other building materials will move forward or backward relative to the truck, and in severe cases, the cab will be pierced, or the building materials will fall off. The occurrence of dangerous situations, causing serious personal and property safety

[0003] Due to the immaturity of the current transportation protection measures, the transportation of building materials such as steel bars is still a big challenge for drivers
