Description

Movable ballastless track bed concrete crushing device

Technical Field

The utility model relates to the technical field of railway maintenance engineering, in particular to a movable ballastless track bed concrete crushing device.

Background

The ballastless track in China has more structural forms, the service environments of the ballastless track have larger difference, and the condition that the track structural parts need to be replaced is unavoidable in the operation process. The replacement of the structural components of the ballastless track of the high-speed railway needs to dismantle the original structure for re-construction, in principle, the construction process is basically consistent with the construction period process, but because the high-speed railway is in the operation period, the line needs to be opened as soon as possible in order to reduce the influence on the running, the existing concrete crushing equipment has low breaking efficiency, occupies large skylight, and can not meet the requirement of replacing the structural components of the ballastless track.

In the replacement operation of structural components of ballastless tracks of high-speed railways, ballast bed concrete breaking is an important link affecting the operation efficiency and the occupation of skylights. At present, the ballast bed concrete breaking mode mainly comprises mechanical chiseling, hydraulic breaking, rope saw cutting and the like. The mechanical chiseling equipment is mainly used for two types of electric hammers and air picks at present. The electric hammer is driven by electric power and can be used by being provided with a generator, so that the electric hammer is the most commonly used concrete breaking equipment at present. The weight of the hammer is used for hammering the real objects on the ground surface by the external force so as to achieve the purpose of crushing. The pneumatic pick uses compressed air as power, and needs to be provided with a generator and an air compressor for use, so that the pneumatic pick is a handheld construction tool for crushing hard objects by utilizing impact, and has a compact structure and is portable for use.

The field test shows that the high-pressure water jet can effectively protect the steel bars in the ballast bed, but the breaking efficiency is lower, and the ballast bed concrete needs to be broken layer by layer. The concrete chain saw does not have installation conditions in the construction of the concrete of the branch area road bed, and the chain saw cuts at a high speed at the rail bottom, so that the risk of damaging the steel rail is caused. In contrast, the traditional mechanical breaking mode is more suitable for breaking ballast bed concrete. The pneumatic pick needs to be equipped with a large-scale air compressor for construction in a road, and is inconvenient to carry. And the electric pick is low in breaking efficiency.

The ballast bed concrete chiseling workload is large and time-consuming, and is the most important link in the whole ballastless track structural part replacement process. Therefore, the rapid chiseling of the ballast bed concrete can save more early preparation time for replacing structural parts.

However, in the process of replacing structural components by adopting the two conventional breaking devices, the concrete chiseling time of the track bed around the single-position double-block sleeper or the single-fork sleeper is at least 8 hours, and the rapid replacement requirement of the damaged structural components in the 4-hour skylight time cannot be met. The hydraulic breaker is favored by the majority of users by virtue of lower working noise and high-efficiency working efficiency. Meanwhile, the hydraulic breaker can work under continuous extreme conditions, including underwater operation at a certain depth, cities, mountainous areas, elevations and the like, which are not achieved by the two broken tools of the electric pick and the pneumatic pick. The research result shows that the hydraulic breaker has higher working efficiency than the blasting construction under the condition of a certain hardness rock according to the rock breaking mechanism, and can replace the blasting construction.

Therefore, in order to meet the requirements of track bed concrete on-site breaking construction, it is highly desirable to design a movable ballastless track bed concrete breaking device based on a hydraulic breaker, which is used for chiseling track bed concrete on site, and further improves the efficiency of track bed chiseling.
