Milling and grinding equipment for railway rail profile

Abstract

A railway rail profile milling and grinding equipment, which includes at least two cars, the car in front according to the working direction is defined as the front car, and the car behind the working direction is defined as the rear car. According to the basic operation sequence of the milling and grinding equipment, the Between the front operation bogie (10) and the rear operation bogie (13) at the lower part of the equipment frame (12) of the front vehicle (A), the milling device (7), the milling function room (6), and the milling device (7) are arranged from front to back. Install the iron chip collecting air compressor (5); on the upper part of the equipment frame of the front car (A), the sequence from front to back is the operating cab (9), and the operating cab (9) also has the function of high-speed operation and the milling device Hydraulic pump station room (8), chip collecting air compressor room for milling device (4), electrical room for milling device (3), screw conveyor for chip collecting (2), chip air compressor air outlet (1), The left and right sides of the iron filings are arranged with belts (15); the rear end of the vehicle frame (12) of the front car (A) is equipped with a wind source system (14) and a coupling traction device (16), and the equipment of the rear car (B) A pneumatic air cylinder system (17) is arranged on the front end of the frame (21) along the working direction, and the diameter of the milling disc of the milling device (7) is not less than 600mm.

Description

technical field [0001] The invention relates to a railway maintenance machine, which is a complete machine layout of rail railway profile milling and repairing equipment. Background technique [0002] The rail reconditioning machine can dynamically mill and grind the rails on the line during operation to eliminate defects such as side grinding, corrugation, rolling layers, cracks, and peeling of the rails, thereby restoring the design shape of the working part of the rail head. The following goals can be achieved: increase the service life of the rail; improve the longitudinal smoothness and cross-sectional profile quality of the rail (reduce rail wear, improve the contact geometry of the wheel and rail, and reduce the relative wear of the wheel and rail); reduce the maintenance cost and reuse cost of the rail; reduce the running Noise improves road network operational safety and operational efficiency. [0003] The traditional rail shaping equipment is mainly a rail grindi...

AI Technical Summary

Problems solved by technology

The rail grinding car has the characteristics of high operating efficiency and flexible grinding in terms of preventive rail shape repair, treatment of lightly diseased rails, line inner rail shape trimming, and special rail profile grinding. The price is high, the amount of maintenance is large, the operation produces more smoke, dust, and sparks, etc., and is not suitable for operation in places with poor environmental conditions such as long tunnels, subways, and light rails; , high-efficiency, high-precision, and environmentally friendly treatment of rail shaping equipment with serious diseases can form a strong complementarity with rail grinding vehicles

[0004] Currently known milling, grinding and shaping equipment adopts two sets of milling devices and one set of milling devices arranged in one car. Due to the limitation of axle load, the diameter structure of the milling disc of the milling device used is small (for example, less than 600mm), so that its inertia is relatively small during milling. Small size, large vertical component force during cutting, unstable operation of the cutter head, short life of the cutter grain, and low operating efficiency
