Description

Technical Field

[0001] The utility model relates to the technical field of turnout grinding instruments, and particularly to a turnout grinding machine. Background Art

[0002] A turnout is an important line connection device that enables locomotives and rolling stock to transfer from one track to another, and is usually laid in large quantities at stations and marshalling yards. With turnouts, the passing capacity of the line can be fully utilized. Even on a single-track railway, by laying turnouts and building a turnout track section longer than the train length, trains can run in opposite directions. Subject to long-term high-load rolling of locomotive wheelsets, turnouts are prone to various damages such as corrugation, burrs, cracks, and spalling, which seriously affect the safe operation of locomotives. The structure of railway turnouts is complex, with many restrictions and constraints, making maintenance difficult.

[0046] Embodiment

[0047] This embodiment provides a turnout grinding machine, which belongs to a small steel track turnout grinding machine and is used for grinding turnouts.

[0048] See Figure 1 and Figure 2 As shown, the switch grinder provided in this embodiment includes a power supply device 10, an electric drive device 40, a grinding device 60, an electric control device 80, and a frame 90; the power supply device 10, the electric drive device 40, the grinding device 60, and the electric control device 80 are respectively connected to the frame 90.

[0049] The electric control device 80 includes a controller 81, an alarm 82, and a discharge current sensor 83 for detecting the discharge current; the alarm 82 and the discharge current sensor 83 are respectively electrically connected to the controller 81; for example, an integrated circuit board is provided in the electric control device 80, and the controller 81, the alarm 82, and the discharge current sensor 83 are integrated on the integrated circuit board. Optionally, the alarm 82 includes a buzzer and / or a warning light, or other alarm structures.

[0050] The electric drive device 40 is drivingly connected to the grinding device 60; that is, the grinding device 60 is installed at the output end of the electric drive device 40. Among them, the grinding device 60 can be the same as the existing steel rail switch grinding mechanism.

[0051] The power supply device 10 and the electric drive device 40 are electrically connected to the controller 81 respectively; the controller 81 is used to control the power supply device 10 to supply power to the electric drive device 40, so that the electric drive device 40 drives the grinding device 60 to work. For example, the electric drive device 40 drives the grinding device 60 to grind the turnout. The controller 81 is also used to receive the discharge information of the power supply device 10 monitored by the discharge current sensor 83, and correspondingly control the alarm 82 and the electric drive device 40. For example, the controller 81 correspondingly controls the alarm 82 to send out corresponding warning information, and correspondingly controls the on-off of the circuit of the electric drive device 40. In this embodiment, the turnout grinder realizes the monitoring of the discharge information of the power supply device 10 through the discharge current sensor 83. Specifically, it mainly monitors the current output to the electric drive device 40. According to the different magnitudes of the monitored current, the controller 81 can correspondingly control the alarm 82 to send out different warning information to achieve the prompt of overload protection. For example, when the current is less than 72A, the load rate of the electric drive device 40 is less than 80%, which is a normal working state, and the controller 81 controls the alarm 82 to send out the first warning information; when the current is between 72A and 90A, the load rate of the electric drive device 40 is 80%-120%, which is a slightly overloaded working state, and the controller 81 controls the alarm 82 to send out the second warning information. This state allows short-term use but not long-term use; when the current exceeds 90A, the load rate of the electric drive device 40 exceeds 120%, which is a severely overloaded state, and the controller 81 controls the alarm 82 to send out the third warning information. This state cannot be used. If it lasts for more than 3 seconds, the controller 81 controls the electric drive device 40 to automatically cut off the power. Wherein, when the alarm 82 includes a buzzer, the buzzer sends out different warning information through the ringing frequency. For example, the first warning information is, for example, that the buzzer rings at long intervals, the second warning information is, for example, that the buzzer rings rapidly, and the third warning information is, for example, that the buzzer rings continuously.

[0052] In this embodiment, the turnout grinder includes a power supply device 10, an electric drive device 40, a grinding device 60, an electric control device 80 and a frame 90. The electric control device 80 includes a controller 81, an alarm 82 and a discharge current sensor 83. The controller 81 is used to control the power supply device 10 to supply power to the electric drive device 40, so that the electric drive device 40 drives the grinding device 60 to work; the controller 81 is also used to receive the discharge information of the power supply device 10 monitored by the discharge current sensor 83, and correspondingly control the alarm 82 and the electric drive device 40. This turnout grinder uses the power supply device 10 and the electric drive device 40 to replace the internal combustion engine as the supporting power device. During operation, the overall vibration and noise are small, and it has the advantages of zero emission, no pollution, convenient carrying, simple operation, etc. Moreover, it is convenient and fast to get on and off the track, which can greatly improve the working environment and is beneficial to the physical and mental health of the operators.

[0053] In view of the fact that the existing small steel track switches grinding machines mainly use internal combustion engines as supporting power devices, the internal combustion engines are not only inconvenient to operate, but also have large overall vibration and noise. At the same time, there are also noise and exhaust gas emissions, which to a certain extent deteriorate the construction environment and increase the labor intensity of the laborers. The exhaust gas emissions not only directly deteriorate the air quality, but also have an adverse impact on the physical and mental health of the construction workers. Therefore, a lithium battery-powered switch grinding machine using a new energy lithium battery as a supporting power device is proposed. The switch grinding machine described in this embodiment uses the power supply device 10 as the power source and the electric drive device 40 to provide power, effectively solving the technical problems brought by using the internal combustion engine as the supporting power device; compared with traditional internal combustion equipment, the power supply device 10 can be applied in some places with poor ventilation such as tunnels and subways or plateau areas. With the steady development of the technology of the power supply device 10, the intelligent degree of the power supply device 10 such as lithium battery equipment will be higher and higher, and the functions will be more and more perfect. In the future, it will surely play a great role in the daily maintenance and emergency repair of railway lines and switch areas.

[0081] 1. The turnout grinder described in this embodiment uses a power supply device 10 as a power source and an electric drive device 40 to provide power, which can reduce the adverse factors such as exhaust gas and noise generated by the traditional internal combustion engine during use.
