AI Technical Summary

Technical Problem

The existing rail web grinding machine has a cumbersome clamping method that can easily damage the rails, and the electrical control box needs to be moved frequently, which makes it inconvenient to operate.

Method used

The design incorporates a tool-feeding clamping mechanism and left and right clamping hook assemblies, combined with an electric push rod and control box, to achieve rapid clamping and release. The grinding wheel makes elastic contact with the rail web, and the control box is fixed by a specially designed push rod clamp, thus optimizing the track structure.

Benefits of technology

The clamping and releasing mechanism is quick and convenient, reducing damage to the rails, preventing the machine from tilting and causing accidents, and simplifying the handling of the electrical control box.

Abstract

The utility model discloses a novel rail web polisher which comprises a bottom frame, walking wheels, an electric push rod, a polishing mechanism, a feed clamping mechanism, a control box, a left clamping claw assembly and a right clamping claw assembly, the walking wheels used for walking are installed at the bottom of the bottom frame, the walking wheels are erected on a steel rail, the electric push rod is installed on the bottom frame, and the polishing mechanism is installed on the electric push rod. A push rod part of the electric push rod is fixed to a steel rail through a clamp, the push rod of the electric push rod extends out to drive the bottom frame to walk, grinding mechanisms used for grinding rail webs are installed on the two sides of the bottom frame, a feed clamping mechanism used for driving the grinding mechanisms on the two sides to rapidly clamp the rail webs or open the rail webs is installed on the bottom frame, and a follow-up control box is installed on the electric push rod. Left and right clamping claw assemblies for preventing the whole machine from inclining are further installed on the two sides of the bottom frame. By means of the mode, the structure is stable, the clamping and loosening modes are rapid and convenient, the grinding wheel makes elastic contact with the rail web, damage to the steel rail is reduced, and the whole machine is prevented from inclining and accidents are avoided.
