Exemplary method
The embodiment provides an automatic grinding method of a steel rail grinding wagon, and the method can be applied to the technical field of steel rail grinding. As shown in fig. 1 in detail, the method includes:
s100, acquiring form detection data of the steel rail through a preset steel rail detection device, and automatically generating a polishing scheme according to the form detection data.
In consideration of the fact that in the prior art, a steel rail grinding control system does not have an automatic grinding function related to the conditions of main lines, turnouts and the like in a steel rail line, generally, in the condition, the state of a steel rail needs to be detected in advance, an operator manually sets grinding pressure and angle according to experience, and after the steel rail reaches a grinding area, the grinding head is manually lowered. The mode of action is easy to damage the steel rail due to misoperation, and the grinding operation can be completed only by an operator with abundant field experience. The steel rail grinding control system is provided with a preset steel rail detection device, the steel rail detection device can acquire form detection data of a steel rail, and then the system compares the form detection data with a set standard profile, analyzes and calculates to automatically generate a set of grinding scheme matched with the form detection data. The polishing scheme specifically comprises the following steps: 1. automatically adjusting the grinding wagon to the optimal operation speed; 2. automatically adjusting the current and the angle of a polishing motor; 3. automatically calculating the number of times of polishing required between polishing operation sections: if the profile and the wave-shaped abrasion damage of the steel rail are serious, the system automatically controls the grinding wagon to carry out reciprocating grinding; 4. automatically detecting the quality requirements of the grinding operation on reaching the standard steel rail profile state, eliminating the wave-shaped abrasion, surface roughness less than or equal to Ra10 mu m and the like. According to the embodiment of the invention, the polishing current and angle do not need to be manually set, and the lifting polishing device does not need to be manually operated, so that the possibility of damage to the steel rail caused by manual misoperation is avoided.
In order to make the grinding scheme more accurate, the form detection data detected by the steel rail detection device needs to be very detailed and accurate. In an embodiment, the step of acquiring form detection data of a steel rail by using a preset steel rail detection device, and automatically generating a grinding scheme according to the form detection data includes the following steps:
s101, acquiring form detection data of the steel rail through the steel rail detection device, wherein the form detection data comprises: rail profile, wavy wear, surface roughness;
step S102, comparing and matching the form detection data with preset standard data to obtain a matching result;
and S103, automatically generating a polishing scheme according to the matching result.
In practice, the steel rail can be used only after meeting the form indexes of the standard, when the steel rail is used for a period of time, the steel rail is worn and possibly causes faults, so the steel rail needs to be overhauled, when some forms of the steel rail are deformed after being overhauled, the steel rail needs to be polished, and all the form indexes of the polished steel rail meet the form indexes of the standard. It is considered that the rail shape data is required to be obtained before rail grinding is carried out, and the more the rail shape data is, the more detailed the rail shape data is, the higher the grinding precision is. Therefore, a rail detection device is required to be provided in the system, and the rail detection device acquires the form detection data of the rail. Specifically, the form detection data comprises the profile of the steel rail, the wave-shaped abrasion and the surface roughness. After the steel rail detection device acquires the form detection data, the form detection data is compared with preset standard data, the preset standard data is the standard form data of the steel rail, and through comparison of the data, the deviation of the form detection data and the preset standard data can be obtained, for example, when the profile of the steel rail is seriously deformed, the grinding strength is increased; when the wavy abrasion is large, the polishing angle needs to be adjusted correspondingly; when the surface roughness of the rail is high, the number of times and time of the repeated grinding are increased accordingly. The matching result is obtained through the deviation of the form detection data and the preset standard data, and the system can automatically adjust the polishing device according to the matching result to generate a corresponding polishing scheme, so that a real-time and accurate polishing effect is realized.
Considering that the automatically generated grinding plan provides a grinding reference for the subsequent grinding operation, the following step S200 is executed to control the grinding device to grind the rail according to the automatically generated grinding plan. Specifically, when the profile of the rail is severely deformed or the rail is severely damaged by wave-shaped abrasion, the system adjusts the grinding device to continuously perform reciprocating grinding. When the surface roughness of the steel rail is very high, the system can control the grinding device to improve the grinding depth, change the grinding angle and increase the grinding times, so that the steel rail can be accurately ground. The automatic polishing function in the embodiment of the invention is convenient and simple to operate, the system automatically detects, calculates and formulates a polishing scheme, and the polishing device is automatically controlled, so that the polishing operation is easier, more accurate and more efficient.
In order to precisely polish a worn steel rail, the system needs to control the polishing device to perform polishing operations according to an automatically generated polishing scheme, and therefore, in this embodiment, the step of controlling the polishing device to polish the steel rail according to the automatically generated polishing scheme includes the following steps:
step S201, starting the polishing device, and controlling the polishing device to be in an operation mode.
And S202, adjusting the motor current and the polishing angle of the polishing device according to the polishing scheme, and automatically polishing the steel rail.
Specifically, when a steel rail needs to be polished, the polishing device is placed on the steel rail, the polishing device is started, the polishing device is controlled to be in an operation mode, an operator can set an initial operation speed, then, according to the polishing scheme, for example, when the profile of the steel rail is seriously deformed, the polishing strength is increased, at the moment, the speed of a polishing vehicle is automatically adjusted to be matched with the polishing speed, the motor current of the polishing device is automatically increased, the polishing angle is automatically increased, and the steel rail is automatically polished; when the wavy abrasion is large, the speed of the grinding wagon is automatically adjusted to be matched with the speed, the motor current of the grinding device is automatically increased, and the grinding angle is automatically adjusted in real time; when the surface roughness of the steel rail is very high, the speed of the grinding wagon is automatically adjusted to be matched with the speed, the motor current of the grinding device is automatically increased, the times and time for repeatedly grinding are increased, and the automatic grinding of the steel rail is realized by adjusting the motor current and the grinding angle of the grinding device through the grinding scheme.
In practical use, grinding device need realize automatic control through the electric energy, still need realize the function of rail of polishing, consequently, this embodiment grinding device includes grinding motor and grindstone, grinding device sets up inside a dolly of polishing, the dolly of polishing is followed rail grinding wagon automatic movement.

The grinding motor and the grinding stone are used for removing the steel rail outline and surface metal. Considering that the grinding device needs to continuously maintain and grind the steel rails of other sections after grinding a certain section of steel rail and realize continuous automatic maintenance and automatic grinding, the grinding device needs to have mobility, so the grinding device is arranged in a grinding trolley, and when the steel rail grinding trolley moves automatically, the grinding trolley can move along with the steel rail grinding trolley. For example, after a preset steel rail detection device on the steel rail grinding wagon acquires form detection data of a steel rail, a corresponding grinding scheme can be automatically generated, the steel rail grinding wagon controls the grinding trolley to grind the steel rail according to the grinding scheme, after the grinding trolley finishes the grinding task of the section of the steel rail, the steel rail grinding wagon can continuously move forwards to realize detection and grinding of other sections of the steel rail, the grinding trolley moves along the moving direction of the steel rail grinding wagon at the moment, and grinding operation is performed on the next section of the steel rail to be ground.
In practice, not all the steel rails are damaged and need to be ground, and only the steel rails influencing the train operation, namely when the steel rail profile and the wave-shaped abrasion damage degree in the form detection data of the steel rails reach the threshold value, the section of the steel rail needs to be ground. Therefore, in this embodiment, according to the automatically generated grinding scheme, the method for controlling the grinding device to grind the steel rail further includes the following steps:
and step 211, when the steel rail profile and the wave-shaped abrasion damage degree in the steel rail form detection data reach a threshold value, automatically controlling the grinding device to repeatedly grind the steel rail.
In an embodiment, when the steel rail profile and the wavy abrasion damage degree in the steel rail form detection data reach threshold values, that is, the steel rail abrasion conditions affect the normal operation of the train and reach the grinding standard of the steel rail, the system may select an appropriate grinding scheme according to the detected steel rail form detection data, repeatedly grind the steel rail according to the grinding scheme until the steel rail form detection data match with preset standard data, which indicates that the steel rail returns to a normal form, and may stop the grinding operation of the steel rail.

step S303, when the polishing angle is adjusted and an obstacle cannot be avoided, lifting the polishing trolley or the polishing head of the polishing device;
and S304, controlling the polishing device to recover the polishing state after the polishing angle is adjusted and the obstacle is avoided. When the polishing device is used for polishing, in order to avoid collision of the polishing device with an obstacle, the obstacle detection device is started, and the obstacle detection device detects a polishing line in real time. Once the obstacle detects that there is an obstacle on the polishing line, adjusting the polishing device, for example, adjusting the polishing angle of the polishing device, avoiding the polishing device from colliding with the obstacle, avoiding damage to track equipment and machines, and when the polishing angle is adjusted and the obstacle cannot be avoided, lifting the polishing trolley or the polishing head of the polishing device, wherein the specific lifting height can be calculated according to the size of the obstacle, the size of the polishing device, the installation position of the polishing device and other data.
