Razvoj potisnega vozička za velike nagibe v ravnih tunelih

Žarn, Matic (author), Duhovnik, Jožef (mentor)

Za problem potiskanja tovornih vlakov pri velikih naklonih je potrebno razviti potisni/zadrževalni voziček. Uporabimo standardne komponente za železniške vagone, kot jih uporabljajo Slovenske železnice. Predstavljeni so posamezni deli vlečnega mehanizma, ki so določeni glede na izračunano potisno silo. V nalogi je prikazano delovanje sistema in postopek razvoja potisnega vozička s hidravličnim kompenzacijskim modulom, da zagotovimo minimalne naletne kontakte. Izberemo ustrezne komponente hidravličnega akumulatorskega sistema, ki ga prikažemo s shemo. Tehnična rešitev potisnega vozička je prikazana s 3D modelom, na podlagi katerega je izvedena analiza napetostnih in deformacijskih stanj.

• Title: Push cart development for larger slopes in straight tunnels

Abstract

A push/hold cart should be developed for purpose of pushing a freight train at larger slopes. We use the standard components for railway wagons used by Slovenian Railways. The individual parts of the towing mechanism are determined according to the calculated thrust force. This thesis presents the operation of the system and the process of developing the push cart with a hydraulic compensating module to ensure minimal contact force. Components of the hydraulic accumulator system are shown by the scheme. The technical solution of the push cart is presented with a 3D model, based on which the structural tension and deformation analysis is performed.
