Description

Technical Field

[0001] This utility model relates to the field of railway maintenance equipment technology, specifically a rail profile grinding machine. Background Technology

[0002] In the railway transportation system, rails are a crucial basic component ensuring the normal operation of the railway. During their service life, rails can develop various surface damages (or "defects"), such as wavy wear, rail surface abrasion, rail surface peeling, severe railside wear, cracks, and rail head crushing. These surface damages develop rapidly, affecting the railway's transport capacity, safety, and economic efficiency.

[0003] Re-welding is a common process for repairing these surface damages. However, due to the presence of the weld (weld seam), existing grinding machines are prone to guide wheel vibration when moving over the weld and its vicinity (due to the unevenness of the weld), resulting in an uneven grinding surface and making the grinding wheel more susceptible to damage, and also affecting operator safety. Therefore, we propose a rail profile grinding machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a rail profile grinding machine. The grinding equipment works by transverse grinding, which can not only grind the side surface of the rail simultaneously, but also effectively avoid jumping and damage to the sanding belt during the grinding process, thus effectively solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rail profile grinding machine, comprising a shell, the lower end of which is an open structure, and a profile groove corresponding to the external rail is provided in the middle of the shell. Fixing frames are fixedly connected to the middle of the left and right sides of the shell, and an electric push rod is fixedly connected to the middle of the outer surface of the fixing frame. A connecting frame is fixedly connected to the telescopic end of the electric push rod, and a side top plate is fixedly connected to the inner end of the connecting frame. A motor is fixedly connected to the middle of the upper part of the front surface of the shell, and a drive wheel is fixedly connected to the end of the motor's output shaft. A control switch assembly is fixedly connected to the upper left side of the front surface of the shell. Driven wheels are rotatably connected to the left and right sides of the upper interior of the shell, and connecting rods are fixedly connected to the left and right sides of the lower interior of the shell. Telescopic rods are fixedly connected to the front and rear ends of the lower surface of the connecting rods, and tensioning wheels are fixedly connected to the telescopic ends of the telescopic rods. The drive wheel, driven wheel, and tensioning wheel are connected by a sanding belt drive, and the inner surface of the side top plate is slidably connected to the inner surface of the sanding belt.

[0006] Wherein: the input terminal of the control switch group is electrically connected to the output terminal of the external power supply, and the output terminal of the control switch group is electrically connected to the input terminals of the electric push rod and the motor respectively.

[0007] Furthermore, it also includes a connecting plate and an auxiliary wheel. A through groove is provided in the middle of the upper surface of the housing. Connecting plates are fixedly connected to the front and rear sides of the upper surface of the housing, and an auxiliary wheel is rotatably connected between the connecting plates. The surface of the auxiliary wheel is in contact with the surface of the sanding belt. The auxiliary wheel can press the sanding belt tightly to prevent the sanding belt from slipping or slipping between the sanding belt and the drive wheel, thereby making the use of the equipment safer.

[0008] Furthermore, the surface of the housing is electroplated with a nickel-based alloy corrosion-resistant layer, and the connecting frame is a detachable structure; the detachable connecting frame makes it convenient for workers to replace the sanding belt, and the electroplating layer on the surface of the housing can extend the service life of the equipment, thereby making the equipment more convenient to use.

[0009] Furthermore, the surface of the side top plate is coated with a silicon carbide wear-resistant coating, and the side top plate is made of polytetrafluoroethylene (PTFE). The silicon carbide wear-resistant coating on the surface of the PTFE side top plate can delay the wear of the side top plate, thereby extending the service life of the equipment.

[0010] Furthermore, both the drive wheel and the auxiliary wheel are rubber-coated wheels, and the surfaces of the drive wheel and the auxiliary wheel are provided with anti-slip grooves in a linear array. The rubber-coated wheels can slow down the wear rate of the equipment, and the anti-slip grooves can prevent the sanding belt from slipping, thereby making the use of the equipment safer and more convenient.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This rail profile grinding machine has the following advantages:

[0012] 1. This grinding equipment operates in a transverse grinding mode, which can not only grind the side surface of the rail simultaneously, but also effectively avoid the occurrence of jumping or damage to the sanding belt during the grinding process.

[0013] 2. The auxiliary wheel can press the sanding belt tightly to prevent it from slipping or slipping between the sanding belt and the drive wheel, thus making the use of the equipment safer.
