A tram rail side concrete cutting equipment

Abstract

The invention relates to a concrete cutting equipment on the rail side of a tram, which includes a frame and a cutter shaft. A fixed ring is fixedly arranged on the frame. A water inlet hole is provided, a drainage channel is coaxially provided in the cutter shaft, and a communication groove connecting the drainage channel and the water inlet ring groove is provided on the cutter shaft, a fixed disc and an extrusion disc are coaxially arranged on the cutter shaft, and the cutter shaft The saw blade is coaxially arranged on the shaft and squeezed and fixed between the fixed disc and the extruded disc. Water outlet holes connected with the drainage channel are arranged at intervals in the circumferential direction of the cutter shaft. The drainage groove connected to the water outlet, the drainage groove is set along the radial extension of the fixed plate; the water flow sequentially passes through the drainage channel, the water outlet, and the drainage groove, and finally the water flow flows out along the surface of the saw blade, and the knife is moved when the water flows through the drainage channel. The heat on the shaft is taken away, realizing synchronous cooling of the saw blade and the cutter shaft, and improving the service life of the equipment.

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.
