Abstract

The invention relates to a multidirectional restraint device for a ballasted track bed, which belongs to the field of ballasted track transportation. The invention includes a reinforced concrete block on the left side of the line, a reinforced concrete block on the right side of the line, a screw rod I, a screw rod II, an internal thread fastening sleeve I, an internal thread fastening sleeve II, an internal thread fastening sleeve III, an internal thread tightening sleeve Locking sleeve Ⅳ, lock nut Ⅰ, lock nut Ⅱ, lock nut Ⅲ, lock nut Ⅳ, stop bolt Ⅰ, stop bolt Ⅱ, stop bolt Ⅲ, stop bolt Ⅳ, nut Ⅰ, nut Ⅱ , Nut III, Nut IV, Sleeper. The invention increases the contact area and depth of the sleeper as a whole and the ballast, increases the horizontal and vertical displacement constraints, and significantly improves the vertical and horizontal resistance and bearing capacity of the sleeper and ballast bed; at the same time, it improves the average force of the ballast , which reduces the maximum force of ballast particles, which is beneficial to reduce the probability of ballast particle breakage, reduce maintenance times, and reduce maintenance; transportation, installation, and disassembly are simple and convenient, and can be reused.

Description

Technical field [0001] The invention relates to a multidirectional restraint device for a ballasted track bed, belonging to the field of ballasted track transportation. Background technique [0002] Ballasted track bed is an important part of rail transit. The parameters of track bed's elasticity, impact resistance, vibration resistance, and movement resistance directly affect the running speed and driving safety of the line. [0003] With the development of modern railway construction with high-speed passenger transportation and heavy freight transportation as the development trend, the impact of vehicles on the track structure has increased exponentially. The defects of insufficient restraint of the existing track bed and insufficient longitudinal and lateral resistance have become increasingly prominent. It causes the ballast to be broken, fluidized or powdered, and the vehicle is unstable. In severe cases, it endangers driving safety and greatly restricts the process of high sp...
