Description

Portable etching equipment for track plate of plate-type ballastless track structure

Technical Field

The utility model relates to a portable board-like ballastless track structure track board etching equipment belongs to the technical field of high-speed railway line maintenance.

Background

In the routine operation and maintenance process of the high-speed railway, in order to conveniently find a fault site, the reference of a mark on a field structure is usually needed for accurate positioning. However, at present, the marks on the on-site structures are mostly painted with paint made of organic materials, and the organic materials are easy to age and fall off due to corrosion of long-term environment, especially ultraviolet rays in sunlight, so that difficulty is increased for determining the positions of the high-speed railways during daily maintenance. Therefore, there is a need for a technique for permanent numbering marks on high speed railway structures that is aesthetically pleasing, low cost, stable in performance, and easy to implement.

To accomplish permanent marking on the track plate, such as etching, the extremely high hardness of the surface of the track plate needs to be overcome. A track slab engraving device is designed in a 'high-speed railway concrete track slab engraving machine (CN 210500873U)', and comprises a rack, a wheel set, a three-axis linkage mechanism, an engraving mechanism, a cooling system and a control system, wherein the device moves on a track through the wheel set, and the engraving of the surface of the track slab is completed through the control system. However, the equipment is bulky, and needs a crane to hoist the equipment to the steel rail, so that the etching process and the cost are increased undoubtedly; in addition, continuous cooling water needs to be provided during the working process, and the use in a dry or water-deficient road section is limited. A track slab engraving device is designed in a laser engraving machine (CN 210498815U) for high-speed railway line concrete, and the device consists of an engraving frame, a laser device, a vertical adjusting device and an electric control cabinet and finishes engraving work in a laser engraving mode. However, the equipment moves on the rail through the wheel set, is large in size and is not easy to carry; in addition, the cost of the laser engraving device is far higher than that of the traditional engraving device, the maintenance cost of the device is higher, and the economy of engraving work completed by using the device is poor. The research shows that the marking machine has simple structure, convenient operation and low cost, such as a hand-held pneumatic marking machine (CN 211165962U) which is convenient to adjust, a mobile hand-held electric marking machine (CN 207955034U) and a portable pneumatic marking machine (CN 211000508U) for plane marking objects, can act on a firing pin through high-pressure gas on the surface of the material so as to finish the etching by high-frequency impact. However, the above devices usually complete etching on materials with soft texture and low strength, and the etched writing on the concrete surface of the high-strength track slab is not clear, the edge is damaged, and the appearance is not beautiful; in addition, the high-pressure gas is used for acting on the firing pin, and a high-power air pump is also needed in the equipment structure, so that the equipment structure is more complicated.

The portable equipment suitable for etching the track slab with the slab ballastless track structure is designed and developed, acts on the surface of the track slab in an electromagnetic transmission mode, can avoid the phenomena of edge damage and peeling, and has attractive etching effect; the device is simple to operate, convenient to carry, stable in performance and low in cost, and can be used for permanently marking the surface of the track slab.
