Elastic bar mounting method and elastic bar mounter

Abstract

The invention relates to an elastic bar mounting method and an elastic bar mounter. The method includes the steps of: adopting an elastic bar mounter that is connected with a mounting bracket elastically on a walking bracket capable of walking on a steel rail; arranging two mounting arms on the mounting bracket by hinge joint; and connecting the upper parts of the mounting arms by a drive mechanism in a driving manner to lead a latch hook device which is used for mounting the elastic bar and arranged at the lower parts of the two mounting arms to expand and contract corresponding to the side surface of the steel rail and complete the mounting of the elastic bar. The elastic bar mounting method adopts mechanical power to generate the holding force of the elastic bar fastener and mounting acting force, thus effectively improving mounting construction efficiency, reducing the labor intensity of the elastic bar mounting construction and ensuring mounting quality. The elastic mounter adopts a hydraulic element to supply a power source, realizes quick and highly efficient mounting of the elastic bar fastener, is reasonable in structural design and simple in operation, does not need to consume large amount of human power, can guarantee mounting quality and is suitable for the continuous walking type operation environment of the steel rail.

Description

technical field [0001] The invention belongs to the spring clip installation technology of railway ballastless track, and in particular relates to a spring clip installation method and a clip installer of a fast clip fastener with a single-layer bottom plate. Background technique [0002] The fast clip fastener SFC with a single-layer bottom plate is suitable for ballastless tracks. This fastening system not only meets the various performance requirements of the fastening system for high-speed railways, but also has its significant advantages: fast installation speed, The amount of maintenance is small, which can greatly save installation and construction costs and operation and maintenance costs. At present, the construction of the Shitai Passenger Railway Dedicated Line in my country has adopted this elastic fastener.

AI Technical Summary

Problems solved by technology

[0003] Although the manufacturer of this type of elastic fastener provided a manual spring installation wrench, during the on-site training, it was found that using a fastener wrench required a lot of manpower for construction. One wrench required 4 people, and one hour of continuous work required a rest. , the manpower consumption is relatively large, the manpower is large at the beginning, and the fasteners can generally be put in place. After a period of operation, due to the lack of physical strength of the personnel, more and more work positions are not in place on the fasteners, and the quality assurance is more difficult.

For a large-scale fastener work area, generally four wrenches and 16 people are required, plus 18 people are needed for the quality inspection team. Only 3 kilometers can be constructed in 8 hours, and the construction efficiency is low.
