Hoisting vehicle for replacing long and heavy parts of high-speed railway turnout and its replacement method

Abstract

The invention discloses a hoisting vehicle and method for replacing of long and heavy parts of a high-speed railway turnout. The hoisting vehicle comprises a rail vehicle body, a fixed portal frame flat vehicle body and a moveable portal frame flat vehicle body which are connected end to end through hooks. The method for replacing of the long and heavy parts of the high-speed railway turnout comprises the following steps that 1, the new long and heavy parts of the high-speed railway turnout are hoisted and fixed; 2, the fixed portal frame flat vehicle body and the moveable portal frame flat vehicle body are unfolded and fixed; 3, the used long and heavy parts of the high-speed railway turnout are hoisted and fixed; 4, the new long and heavy parts of the high-speed railway turnout replace the used long and heavy parts of the high-speed railway turnout; and 5, the fixed portal frame flat vehicle body and the moveable portal frame flat vehicle body are folded. The hoisting vehicle and method have the advantages that according to the mechanical device designed special for the long and heavy parts of the high-speed railway turnout, the current defect of secondary hoisting of the new and used long and heavy parts of the high-speed railway turnout is overcome, and thus the site operation time is saved greatly. In the safety aspect, the operation range of the equipment is below that of a lifting beam, so that the hidden danger that the equipment collides a contact net is avoided. In the aspect of comparing the equipment cost, the equipment investment of the newly-proposed method is quite low, and thus popularization is easy.

Description

Technical field: [0001] The invention relates to railway maintenance equipment, in particular to a hoisting vehicle for replacing long and heavy parts of a high-speed railway turnout and a method for replacing long and heavy parts of a high-speed railway turnout. Background technique: [0002] In recent years, with the development of high-speed railways and the increase in passenger traffic, more and more long and heavy parts such as movable frogs, point rails, and basic rails have been repaired and replaced in turnouts of high-speed railway lines. Complex, limited by catenary interference, the long and heavy parts of high-speed rail turnouts are long and heavy, which leads to the fact that large-scale lifting equipment cannot be used when the long and heavy parts of high-speed rail turnouts are safely placed on both sides of the line and replaced safely. Currently, rail cranes are used Hoisting has the disadvantages of secondary hoisting of long and heavy parts of high-spee...

Problems solved by technology

[0002] In recent years, with the development of high-speed railways and the increase in passenger traffic, more and more long and heavy parts such as movable frogs, point rails, and basic rails have been repaired and replaced in turnouts of high-speed railway lines. Complex, limited by catenary interference, the long and heavy parts of high-speed rail turnouts are long and heavy, which leads to the fact that large-scale lifting equipment cannot be used when the long and heavy parts of high-speed rail turnouts are safely placed on both sides of the line and replaced safely. Currently, rail cranes are used Hoisting, there are disadvantages such as secondary hoisting of long and heavy parts of high-speed railway turnouts, high equipment costs, long time consumption, and potential safety hazards
