High-speed train ballastless track bed concrete construction surface line-to-line transport device and method

Abstract

The invention discloses a high-speed train ballastless track bed concrete construction surface line-to-line transport device and method. The device comprises two walking rails, a concrete stirring transport cart and a concrete belt conveyor; the two walking rails are symmetrically installed between a left ballastless track bed and a right ballastless track bed, the concrete stirring transport cart is arranged on the walking rails through first idler wheels, one end of the concrete stirring transport cart is connected with the concrete belt conveyor, the concrete belt conveyor is arranged on the walking rails through a second idler wheel, and a concrete conveying outlet of the concrete belt conveyor right faces a feeding opening of the concrete stirring transport cart. Through the walking rails, concrete is conveyed in an oriented walking manner, the problems that a ballastless track bed pouring working face construction site is narrow, and concrete transport interferes with other working procedures are effectively solved, concrete line-to-line transport can be rapid, convenient and smooth, the concrete is conveyed to the pouring face and directly unloaded into a die, and construction is safe, convenient and fast; and compared with hoisting of concrete blocks with a gantry crane, ballastless track bed pouring is continuous and rapid, pouring quality is guaranteed, and pouring efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, and in particular relates to a rail transportation device and method between the concrete construction surface lines of a ballastless ballast bed of a high-speed railway. Background technique [0002] In order to prevent cracking, the slump of the concrete of the double-block ballastless track bed is controlled at 140-150 mm, and it is poured into the mold by buckets or directly into the mold; the logistics organization during the simultaneous pouring construction is a difficult problem. [0003] At present, rail-mounted gantry cranes are mostly used on the working face to vertically lift the concrete to the pouring face and put it into the mold; due to space constraints, and each process operation shares a single channel, the construction space is narrow, and there is a lot of mutual influence and interference. Faced with the large variety and quantity of construction machinery, m...
