Referring to fig. 2, based on the hardware environment of the foregoing embodiment, an embodiment of the present application provides a method for quickly disassembling an engine thrust pin, including:
S10: obtaining a theoretical tension value of the trolley bracket; when the target engine is not used, the theoretical tension value is horizontally placed on the trolley bracket, so that the trolley bracket receives the tension value; the overhead trolley bracket is used for supporting the target engine.
In particular implementations, the target engine refers to an engine that requires removal of the thrust pin from the engine. The bracket of the trolley is mainly used for supporting the target engine when the target engine is installed or detached; the head of the trolley bracket is provided with two support hinge seats, the two support hinge seats are symmetrically arranged, the tail of the trolley bracket is provided with two rear pull rods which are symmetrically arranged, the upper ends of the rear pull rods are provided with rear pull rod hinge points, and the support hinge seats and the rear pull rod hinge points support the target engine. The target engine is arranged on the trolley bracket horizontally before the installation cabin, and the thrust pin is not stressed by the target engine basically because the target engine is arranged on the trolley bracket horizontally. At this time, as shown in fig. 3, fig. 3 is a schematic diagram illustrating stress analysis when the target engine is in a horizontal state in the embodiment of the present application. In fig. 3, F 1 represents the supporting force applied to the support hinge support when the trolley bracket is positioned in the horizontal direction, F 2 represents the theoretical pulling force applied to the trolley bracket, G 0 represents the weight of the engine, L 0 represents the linear distance from the center of gravity of the engine to the support hinge support on the trolley bracket, L 4 represents the arm of force applied to the support hinge support on the trolley bracket, α represents the angle between the line between the center of gravity of the engine and the support hinge support on the trolley bracket and the horizontal plane, and L 2 represents the distance from the rear pull rod hinge point on the trolley bracket to the support hinge support. According to the geometric relation of the target engine mounted on the trolley bracket, the theoretical tension value of the trolley bracket is obtained through the following relation:
wherein, F' 1 represents the supporting force of the support hinge support when the trolley bracket is located in the horizontal direction (corresponding to F 1),F'2 in fig. 1 represents the theoretical pulling force value of the trolley bracket (corresponding to F 2),G0 in fig. 1, L 0 represents the linear distance from the center of gravity of the engine to the support hinge support on the trolley bracket, L 4 represents the arm of force of the supporting force of the support hinge support on the trolley bracket, α represents the angle between the connecting line of the center of gravity of the engine and the support hinge support on the trolley bracket and the horizontal plane, and L 2 represents the distance from the rear pull rod hinge point on the trolley bracket to the support hinge support).
Because the target engine is a high-quality product, the tension value of the target engine cannot be directly measured on the target engine, the tension value of the bracket of the trolley is converted into the calculated tension value, and the tension value of the target engine can be known according to the force interaction relation, so that the stress of the thrust pin is known.
S11: and controlling the trolley bracket to move to a clearance position between the installation cabin and the target engine so that the trolley bracket supports the target engine.
In the specific implementation process, when the thrust pin arranged on the target engine in the installation cabin is detached, the trolley bracket is controlled to move to a gap between the installation cabin and the target engine in a conventional mode, and then the trolley bracket is controlled to support the target engine, and the target engine is mainly supported through the support hinge seat and the rear pull rod hinge point during support. Thus, the target engine can be conveniently disassembled, and the tension value of the target engine can be obtained indirectly through the trolley bracket.
S12: obtaining an actually measured tension value of the trolley bracket; the actually measured tension value is a tension value received by the trolley bracket after the target engine is used and is placed on the trolley bracket.
In the specific implementation process, two main methods are available for obtaining the measured tension value of the trolley bracket. The first method is to install a tension sensor at the tail of the trolley bracket, and obtain the measured tension value of the trolley bracket through the tension sensor. The pull sensor is a conventional sensor, the model of which can be selected according to actual needs, and the working principle and circuit connection of the pull sensor are also known to those skilled in the art. The tension sensor is used for measuring the tension value received by the trolley bracket in real time, so that the actually measured tension value received by the trolley bracket can be obtained quickly, and the trolley bracket can be adjusted correspondingly more conveniently.
In the second method, as shown in fig. 4 (here, the head position of the engine is lower than the tail position is taken as an example), fig. 4 is a schematic diagram of stress analysis when the head position of the target engine is lower than the tail position in the embodiment of the present application. In fig. 4, F 2y represents the tangential force to which the trolley bracket is subjected, G 0 represents the weight of the engine, L 0 represents the linear distance from the center of gravity of the engine to the support hinge support on the trolley bracket, L 4 represents the arm of force of the support hinge support on the trolley bracket, α represents the angle between the line connecting the center of gravity of the engine and the support hinge support on the trolley bracket and the horizontal plane, β represents the angle between the axis of the engine and the horizontal plane, L 2 represents the distance between the rear tie rod hinge point on the trolley bracket and the support hinge support, L 3 represents the arm of tangential force to which the trolley bracket is subjected, ψ represents the angle between the tension sensor and the horizontal plane, and H represents the initial height of the tension sensor. And obtaining the measured tension value received by the trolley bracket according to the geometric relation of the trolley bracket when supporting the target engine. Specifically, as shown in fig. 5, step S12 includes the steps of:
s121: and obtaining the supporting force born by the supporting hinged support on the trolley bracket.
In the specific implementation process, the supporting force born by the supporting hinged support on the trolley bracket is obtained by the following relational expression:
Wherein, F 1 represents the supporting force on the bracket of the trolley, beta represents the included angle between the axis of the engine and the horizontal plane, and phi represents the included angle between the tension sensor and the horizontal plane.
S122: and obtaining tangential force received by the trolley bracket based on the supporting force received by the support hinged support on the trolley bracket.
In the specific implementation process, the tangential force suffered by the trolley bracket is obtained through the following relation:
Wherein, F 2y represents the tangential force that the overhead traveling crane bracket receives, L 3 represents the arm of force of the tangential force that the overhead traveling crane bracket receives.
S123: based on the tangential force received by the trolley bracket, the actually measured tension value received when the head of the trolley bracket is lower than the tail of the trolley bracket is obtained.
In the specific implementation process, the actually measured tensile force value received when the head part of the trolley bracket is lower than the tail part is obtained through the following relation:
wherein F 2 represents the measured tension value received by the trolley bracket, and H represents the initial height of the tension sensor.
The measured tension value of the trolley bracket, which is obtained through the geometric relationship, is more accurate, and the obtained measured tension can be compared with the measured tension obtained by the tension sensor so as to be used as a reference for the measured tension obtained by the tension sensor.
S13: and comparing the actually measured tension value with the theoretical tension value to obtain a comparison result.
In the specific implementation process, the comparison of the measured tension value and the theoretical tension value can generate the following three conditions: firstly, under the condition that the measured tension value is larger than the theoretical tension value, a first result is obtained; wherein the first result is used to characterize that a head position of the target engine is lower than a tail position. Secondly, under the condition that the measured tension value is equal to the theoretical tension value, a second result is obtained; wherein the first result is used to characterize the target engine as being in a horizontal direction. Thirdly, under the condition that the actual measurement tension value is smaller than the theoretical tension value, a third result is obtained; wherein the third result is used to characterize the target engine with a head position higher than a tail position.
Therefore, the stress condition of the thrust pin is converted into the tension condition of the target engine, the tension condition of the target engine is converted into the tension condition of the trolley bracket, and the stress condition of the thrust pin can be more intuitively reflected by quantifying and comparing the theoretical tension condition and the actually measured tension condition of the trolley bracket, and the thrust pin is detached according to the stress condition of the thrust pin.
S14: and controlling the trolley bracket to adjust based on the comparison result so as to detach the thrust pin on the target engine.
In the specific implementation process, the trolley bracket is adjusted according to the three comparison results in the step S13, and finally the purpose of detaching the thrust pin from the target engine without damage is achieved. Wherein, the mode of adjusting the trolley bracket comprises manual adjustment or program control. Specifically, if the first result is obtained, controlling the head of the trolley bracket to be adjusted up or controlling the tail of the trolley bracket to be adjusted down so that the actually measured tension value is equal to the theoretical tension value; if the third result is obtained, controlling the tail of the trolley bracket to be adjusted up or controlling the head of the trolley bracket to be adjusted down so that the actually measured tension value is equal to the theoretical tension value; and if the second result is obtained, disassembling the thrust pin on the target engine.
In this embodiment, the actually measured tension value and the theoretical tension value are compared, if the actually measured tension value is greater than the theoretical tension value, the head position of the target engine is indicated to be lower than the tail position, the times need to control the head of the trolley bracket to be heightened or control the tail of the trolley bracket to be lowered, and finally the trolley bracket is basically in the horizontal position. If the measured tension value is smaller than the theoretical tension value, the head position of the target engine is higher than the tail position, at the moment, the head of the trolley bracket needs to be controlled to be lowered or the tail of the trolley bracket needs to be controlled to be raised, and finally the trolley bracket is basically in the horizontal position. If the measured tension value is equal to the theoretical tension value, the head position and the tail position of the target engine are basically the same, namely the target engine is in a horizontal position. When the carriage is in the horizontal position, the target engine is also in the horizontal position, and when the target engine is in the horizontal position, the thrust pin is substantially not stressed by the target engine. At this time, the thrust pin is detached from the target engine, and damage to the thrust pin is not easily caused.
Therefore, the application firstly moves the bracket of the mounting vehicle on the gesture adjusting platform to the gap position between the target engine and the engine mounting cabin, so that the interface of the arc-shaped support hinged support on the bracket of the mounting vehicle is fully contacted with the supporting point of the engine, and the tension sensor arranged at the tail end of the bracket of the mounting vehicle can detect the actual weight borne by the bracket in real time through the gesture adjusting of the platform; then, according to the actual measurement value of the tension sensor and the theoretical value in the installation vehicle system, the posture (head-up/head-down) of the current target engine is found, the posture of the target engine is adjusted through the posture adjusting mechanism of the installation vehicle, and when the actual measurement value of the tension sensor is equal to the theoretical value in the installation vehicle system, the engine is in a horizontal position, namely in a stress-free state; and finally, the operator removes the rear end and the front end of the engine to clamp the fixed point, removes the thrust pin of the engine, and orderly withdraws the engine from the installation cabin. Therefore, the quick disassembly of the thrust pin of the engine can be realized, and the scrapping loss caused by the disassembly of the thrust pin of the engine with stress is avoided. The application breaks through the bottleneck that the disassembly of the thrust pin of the current engine depends on the experience of operators, quantifies the stress value of the thrust pin of the engine before the disassembly, eliminates the stress of the thrust pin of the engine and the installation cabin through the posture adjustment of degrees of freedom such as pitching, rolling and lifting of the installation platform, ensures the stress-free disassembly of the thrust pin, and reduces the risk of the surface crush injury of the thrust pin. The state of the target engine can be clearly judged by quantifying the stress value of the engine, the dependence on experience of skilled personnel is reduced, the posture adjustment time for disassembling the thrust pin of the target engine is greatly saved, meanwhile, the target engine can be effectively prevented from being disassembled with stress, the disassembly quality is improved, and the method has a strong practical application value.
In summary, since the actual tension value of the bracket supporting the target engine can reflect the tension of the target engine, the tension of the target engine can reflect the stress condition of the thrust pin. And the theoretical tension value and the actual tension value received by the trolley bracket are quantized, so that the obtained theoretical tension value and actual tension value are accurate. Therefore, the stress condition of the thrust pin on the engine can be accurately judged through the quantized actual tension value of the trolley bracket. Because the stress condition that the thrust pin receives the engine can be judged more accurately, the trolley bracket and the target engine can be regulated more accurately, and the target engine can be regulated to the horizontal position more accurately, so that the stress that the thrust pin receives the target engine is smaller, and the thrust pin is less prone to being damaged when being disassembled.
