Tramcar rail side concrete cutting equipment

Abstract

The invention relates to tramcar rail side concrete cutting equipment. The device comprises a rack and a cutter shaft, a fixing ring is fixedly arranged on the rack; the fixing ring and the cutter shaft are in rotary sealing connection to form a water inlet ring groove; a water inlet hole is formed in the fixing hole; a drainage channel is coaxially formed in the cutter shaft; a communicating groove for communicating the drainage channel with the water inlet ring groove is formed in the cutter shaft; a fixed disc and an extrusion disc are coaxially arranged on the cutter shaft; saw blades fixed between the fixed disc and the extrusion disc in an extrusion mode are coaxially arranged on the cutter shaft, water outlet holes communicating with the drainage channel are formed in the cutter shaft in the circumferential direction at intervals, liquid discharging grooves communicating with the water outlet holes are formed in the fixed disc in the circumferential direction facing the saw blades at intervals, and the liquid discharging grooves extend in the radial direction of the fixed disc; water flow sequentially passes through the drainage channel, the water outlet groove and the liquid discharging groove and finally flows out along the surface of the saw blade, heat on the cutter shaft is taken away while the water flow passes through the drainage channel, synchronous cooling of the saw blade and the cutter shaft is achieved, and the service life of equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of cutting equipment, in particular to a concrete cutting equipment on the track side of a tram. Background technique [0002] At present, the so-called tram level crossing refers to the level crossing of the railway and the road corresponding to the tram. The level crossing is the main throat in the railway transportation and road transportation. There are two forms of greening section and hardening section, because the significance of the tram is that it can share the right of way with the urban green belt (lawn) or asphalt pavement, and the hardening section embeds the track in asphalt concrete. Since the asphalt concrete is close to the rigid structure, Collision with rails is prone to fatigue and cracking, and the interface adhesion is poor, and water can easily seep into the interface, causing freeze-thaw or corrosion of the lower structure. The rail top sealing layer also plays the role of flexible c...

Problems solved by technology

[0007] When the saw blade cuts the ground, the saw blade is easily damaged by heat and aging. Usually, a water spray pipe is installed on the road cutting machine base. There will be water splashing when it is sprayed on the saw blade. Moreover, because the saw blade rotates at a high speed when the road cutting machine is working, the residence time of the cooling water on the surface of the saw blade is very short, and the cooling water has not been completely absorbed into the saw blade. The heat on the saw blade is splashed, and the cooling effect is not fully played. The use efficiency of cooling water is very low. In order to strengthen the cooling effect of the saw blade, it is necessary to increase the amount of cooling water sprayed, resulting in a waste of water resources.
