Problems solved by technology

This operation method requires a lot of labor and takes a long time. A single sleeper is 2.5m long and weighs about 400kg. The length and weight of the sleepers in the fork area are larger than the line sleepers.
Therefore, removing ballast and replacing sleepers is a combination of relatively heavy manual labor and precision technology in the current line maintenance method, and the throat area is densely covered with lines, and the working space is limited. In addition, the number of operators is concentrated. The operating time is strictly limited, and there are potential hidden dangers to the personal safety of the operators.
[0004] So far, there is no effective method of replacing the railway line sleepers, based on this, we have invented a method for efficiently replacing the railway line sleepers

Embodiment Construction

[0042] The present invention will be further described below in conjunction with the specific embodiments and the accompanying drawings.

[0043] see figure 1 and Figure 4-Figure 7 , the method for efficiently replacing railway track sleepers among the present invention, comprises the following steps:

[0044] S1 Ballast removal and recovery: fix the ballast recovery and backfill mechanism on the basic rail 8, and the electric shovel 2 moves forward along the guide rail 1 under the drive of the stepping device to shovel out the ballast, and the shoveled out ballast passes through the horizontal conveyor belt 4 and the upper The conveyor belt 5 is transported into the ballast storage frame 6; before the ballast is transported into the ballast storage frame 6, the cleaning operation is carried out to remove fine particles and dust, which can increase the porosity between adjacent ballasts after the ballast is backfilled, Prevent fine particles from filling the gaps between ba...

Abstract

The invention relates to the technical field of railway line maintenance, and in particular relates to a method and device for efficiently replacing a railway line sleeper. The method comprises the steps that S1 ballast is taken recovered; S2 the sleeper is extracted; S3 the sleeper is hoisted to an installation position, specifically, a sling of a winch below a rotating suspension arm is connected with the sleeper needing to be installed, and under driving of a first motor, the rotating suspension arm rotates around a first rotating shaft to convey the sleeper needing to be installed to the installation position; S4 the sleeper penetrates through the lower portion of a stock rail, and replacement of the sleeper is completed; and S5 stone ballast backfilling is conducted, specifically, a horizontal conveying belt and an upper conveying belt reversely convey the stone ballast for stone ballast backfilling. The method for efficiently replacing the railway line sleeper has the advantages that the operation labor intensity is low, and people do not need to lift and carry the sleeper on shoulders, in the operation process, only one person is needed to operate equipment, two persons cooperate for operation, and compared with traditional operation, the consumed time is shortened by more than one half; and the time for replacing one wooden sleeper can be controlled within 30 minutes (excluding the material conveying time).

Description

technical field [0001] The invention relates to the technical field of railway line maintenance, in particular to a method and device for efficiently replacing railway track sleepers. Background technique [0002] Railway is the main artery of the national economy, key infrastructure and major livelihood projects. It is the backbone of the comprehensive transportation system and one of the main modes of transportation. Its position and role in economic and social development are crucial. [0003] Replacing sleepers damaged by vehicle rolling or stone ballast friction (including turnout sleepers in the throat area of ​​the station) is a common task in the daily maintenance of railway lines. Now the common operation method is to manually take ballast, take out damaged sleepers, put into new sleepers, fill ballast, and tamp. This method of operation requires a lot of labor and takes a long time. A single sleeper is 2.5m long and weighs about 400kg. Therefore, removing ballast...
