Problems solved by technology

The hoisting and laying of sleepers is an important process in the construction of ballastless track, but there is no special device for hoisting and laying of sleepers. Therefore, the construction efficiency is low and the safety is poor, which is difficult to meet the construction of modern double-block ballastless track system. Require

Abstract

The invention relates to a sleeper hoisting layout device meeting the construction of a dual block-typed ballastless track system. The sleeper hoisting layout device comprises a middle beam, a driving rotary connection device connected with the middle part of the middle beam, a middle clipping sleeper beam connected with the lower part of the middle beam, a front stretching and sliding frame bearing device and a rear stretching and sliding frame bearing device arranged on the two sides of the middle beam, two clipping sleeper beams arranged parallelly to the middle clipping sleeper beam and respectively arranged below the front, and rear stretching and sliding frame bearing devices, and five clipping sleeper beams composed of the above components and a spacing limit adjusting mechanism arranged among each clipping sleeper beam. The invention has the advantages that: firstly, the invention can be matched with prior equipment for usage, and has simple structure, compact and rational arrangement, and high automation; secondly, the invention can complete the series processes of sleeper clipping, sleeper dispersing and sleeper dropping of a plurality of sleepers once, not only the operation is convenient, the construction efficiency is high and the safety and reliability are strong, but also the positioning is accurate, and the precision of sleeper layout is high; thirdly, the invention can realize the assembling and disassembling, the transporting and the stacking of the dual block type sleeper.

Description

technical field [0001] The invention relates to a device capable of satisfying the requirements for the construction of a double-block ballastless track system, in particular to the hoisting and laying of a double-block sleeper for grasping, loosening, aligning and laying out the double-block sleeper to complete a series of procedures for laying the track device. Background technique [0002] Ballastless track is a track structure with high track stability, good rigidity uniformity, strong structural durability, significantly reduced maintenance workload and relatively mature technology. It uses formed composite materials instead of ballast to distribute wheel-rail force And pass it to the subgrade foundation to improve the stability, safety and comfort of passenger-dedicated train operation, and become the preferred track type for passenger-dedicated lines. The hoisting and laying of sleepers is an important process in the construction of ballastless track, but there is no...
