Embodiment 1

[0037] Such as figure 1 and Figure 6 As shown, the present embodiment provides a portable rail corrugation grinding machine for corrugating and grinding the rail 7, including a support beam 14, one end of the support beam 14 is provided with a support device, and the other end is provided with a grinding device. It includes a grinding mechanism frame 4, a clamping guide assembly for clamping and guiding the rail and a grinding assembly for moving relative to the rail and grinding the rail. There are two clamping guide assemblies, which are respectively located on the grinding mechanism frame 4. At the end, there are multiple grinding components connected to the bottom of the grinding machine frame 4, and sequentially arranged between two clamping guide components. The support beam 14 is vertically arranged with the grinding machine frame 4 .

[0038] The grinding mechanism frame 4 is kept parallel with the standard rail surface, and all devices of the whole grinding machine...

Embodiment 2

[0046] Such as Figure 4 and Figure 5 As shown, in the present embodiment, the transmission wheel 2 of the adjacent grinding assembly is located on the same side of the transmission wheel shaft 5, and the grinding wheel support 3 is fixedly connected to the grinding mechanism frame 4, between the transmission wheel shaft 5 and the bearing 10, between the transmission wheel shaft 5 and the Transmission wheel 2 is all provided with a guide mechanism for guiding the lateral movement of grinding wheel 9, so that the grinding wheel grinding head in the middle has transverse momentum, which is suitable for grinding of a single rail wave-type wear in a curved section with small radius. All the other are with embodiment 1.

Abstract

The invention relates to a light-weight and convenient type steel rail corrugation grinding machine, which is used for performing corrugation grinding on a steel rail. The light-weight and convenient type steel rail corrugation grinding machine comprises a support transverse beam, wherein a support device is arranged at one end of the support transverse beam, a grinding device is arranged at the other end of the support transverse beam, the grinding device comprises a grinding mechanism frame, two clamping and guiding assemblies and a plurality of grinding assemblies, the clamping and guiding assemblies are used for clamping and guiding the steel rail, each grinding assembly is moved relative to the steel rail and is used for grinding the steel rail, the clamping and guiding assemblies are respectively arranged at the two ends of the grinding mechanism frame, and the grinding assemblies are connected with the bottom part of the grinding mechanism frame, and are sequentially arranged between the two clamping and guiding assemblies. Compared with the prior art, the light-weight and convenient type steel rail corrugation grinding machine has the advantages that the cost is low, the grinding efficiency is high, the control is simple and reliable, the structure is compact, the stability is good, the firmness and durability are realized, and the like.

Description

technical field [0001] The invention relates to the field of wavy abrasion grinding of rail rail surfaces of rail transportation, in particular to a portable rail wavy grinding machine for grinding curved monorails of subways. Background technique [0002] With the rapid development of my country's underground railways, rail and train vibrations caused by rail corrugation on small-radius curves have a prominent impact on train driving safety, stability, and ride comfort. Borrowing rail grinding vehicles on main lines to carry out a short-length metro curve Grinding is not only expensive, but also does not match the technical parameters. Chinese patent CN103911926A discloses a rail grinding vehicle, which includes a frame body, a grinding unit is arranged on the frame body, a running wheel is provided at the bottom of the frame body, the frame body is suspended on the grinding train, and the distance between the frame body and the grinding train is There is a lifting hydrauli...
