Operation method for improving sleeper replacement efficiency and reducing personal potential safety hazards

Abstract

The invention discloses an operation method for improving sleeper replacement efficiency and reducing personal potential safety hazards, and relates to the technical field of railway construction. The method comprises the following steps that cooperation personnel quickly loosen about forty cement sleeper binding nuts in the front in advance, remove elastic strips, pinch plates and the like, and then replace the sleeper in a five-in-five-out mode in a rotating mode; the cooperation personnel quickly insert the prepared clamping plates into cement sleeper bolts with nuts on the outer side of a steel rail, tighten screw openings through an electric wrench, continue to loosen twenty-five cement sleeper fastener nuts in front of the sleeper replacing machine and remove and collect the elastic strips, the buckle plates and the like, and the operation is repeated. According to the operation method for improving the pillow replacement efficiency and reducing the personal potential safety hazards, the pillow replacement efficiency can be improved by about 50%, and the square pillow penetrating efficiency can be improved by 90%-130%; due to the fact that only two cooperation persons are needed and do not need to work under the bottom of the end of the sleeper changing machine, the potential safety hazards are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to an operation method for improving the efficiency of pillow replacement and reducing hidden dangers of personal safety. Background technique [0002] At present, the pillow changing mode is basically unified: one operator operates the pillow changing machine equipment, and the following two (or four) cooperate with the personnel to tighten the screws, install fasteners, elastic strips, adjust the position of the cement pillow, etc. A security commander coordinates to ensure the safety of cooperating personnel. This mode of changing pillows has become a common practice (at home and abroad), and the speed of changing pillows is relatively slow, with an average of about 25 pillows per hour-30 pillows per hour. Simultaneously, there is following shortcoming in this pillow-changing mode: 1, " people stop and stop, promptly machine waits for people, and people waits for ma...

Problems solved by technology

This mode of changing pillows has become a common practice (at home and abroad), and the speed of changing pillows is relatively slow, with an average of 25 pillows per hour-30 pillows per hour.

Simultaneously, this mode of changing pillows has the following disadvantages: 1. "People stop and stop, that is, the machine waits for people, and people wait for machines." When changing a pillow, both people and machines must stop and wait for each other.

For example, if you change a cement pillow for two minutes, the pillow changing machine will work for 3 / 5 of the time (on average, about 1.2 minutes for ballast removal, pillow extraction, and pillow replacement) and then stop waiting for manual work; the coordinating personnel will work for 2 / 5 of the time ( On average, the work of tightening screws, installing fasteners, elastic strips, and adjusting the position of cement pillows takes 0.8 minutes), and there is a long waiting time for intermediate mechanical equipment; work under the head of the pillow machine), it must be coordinated by multiple parties, and a slight omission will cause casualties; 3. The physical labor intensity of the coordinating personnel is relatively high and the sensitivity requirements are high
