The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0053] The following describes the method, device, electronic device and storage medium for calculating the cylinder diameter of an articulated jack according to an embodiment of the present invention with reference to the accompanying drawings.

[0054] Figure 1 4 is a flow chart of a method for calculating the cylinder diameter of an articulated jack according to an embodiment of the present invention.

[0055] like Figure 1 As shown, the method for calculating the cylinder diameter of the articulated jack according to the embodiment of the present invention comprises the following steps:

[0056] S1, determine the supporting force F of the top beam, the first horizontal distance l1 from the position of the supporting force F to the origin of the coordinate system, and the initial top beam load distribution curve containing unknown parameters; wherein the X-axis of the coordinate system is along the horizontal direction where the hinged beam and the top beam are located, the Y-axis of the coordinate system is perpendicular to the horizontal direction where the hinged beam and the top beam are located, and the origin of the coordinate system is the end of the hinged beam away from the top beam.

[0057] It should be noted that the coordinate system of the present invention is established with reference to Figure 2 In this step, for the articulated top beam, the size of the support force F of the top beam and the position point where the force acts on the top beam can be determined according to the frame structure of the hydraulic support.

[0058] S2, obtain the vertical distance h from the hinge point E to the center line of the hinge jack, and the second horizontal distance L from the origin of the coordinate system to the hinge point E J , the third horizontal distance L from the origin of the coordinate system to the end of the top beam away from the origin of the coordinate system, the fourth horizontal distance l2 from the point of action of the support force F to the end of the top beam away from the origin of the coordinate system, the fifth horizontal distance Δl from the origin of the coordinate system to the coal wall along the X-axis direction of the coordinate system and the opening pressure P of the articulated jack safety valve; among which, the hinge point E is the connection point between the articulated beam and the top beam.

[0059] In this step, if the supporting force of the top beam is F, the top beam exterior is regarded as a continuously distributed load with a degree q, where the initial top beam load distribution curve F(x) represents the strength of the load at x, then based on the static equilibrium condition, the following formulas (1) and (2) can be obtained:

[0060]

[0061] Based on the initial top beam load distribution curve F(x) as ax nBased on the exponential function distribution characteristics, the initial top beam load distribution curve F(x) is expanded into a quadratic polynomial according to the Taylor formula, and the following formula (3) is obtained:

[0062] q=F(x)=a+bx+cx 2 (3)

[0063] If the fifth horizontal distance from the origin of the coordinate system to the coal wall along the X-axis direction of the coordinate system is Δl, for the coordinate system xoy, the coordinate of point D is (-Δl, 0). If the load concentration of point D is q=d, substitute the coordinate of point D into formula (3), and we have F(-Δl)=d, and get the following formula (4):

[0064] ab·Δl+c·(Δl) 2 =d (4)

[0065] Combining the above formulas (1) to (4), the following equation group (5) is established:

[0066]

[0071]

[0072] S4, updating the initial top beam load distribution curve according to the calculated parameter values ​​of the unknown parameters to obtain a target top beam load distribution curve.

[0073] In this step, the obtained values ​​of a, b, and c are substituted into the initial top beam load distribution curve F(x)=a+bx+cx 2 The target top beam load distribution curve can be obtained.

[0074] S5, according to the target top beam load distribution curve, the vertical distance h and the second horizontal distance L J , calculate the thrust T of the articulated jack.

[0075] According to one embodiment of the present invention, according to the target top beam load distribution curve, the vertical distance h and the second horizontal distance L J , calculate the thrust T of the articulated jack, including:

[0076] The difference between the target top beam load distribution curve and each point (L J -x) to obtain the first product value;

[0077] In the interval [0, L J ] to integrate the first product value to obtain an integral value;

[0078] The first quotient obtained by dividing the integrated value by the vertical distance h is taken as the thrust T.

[0079] Since the ideal working state of the articulated jack is that the load curve on the articulated beam should be exactly the same as the load curve on the top beam, the moment of the hinge point E between the top beam and the articulated beam is taken to obtain the following formula (8):

[0080]

[0081] Substituting the formula of the target top beam load distribution curve into the above formula (8), the following formula (9) is obtained:

[0082]

[0083] The thrust T required by the articulated jack can be solved by formula (9).

[0084] S6. Calculate the cylinder diameter D required for the articulated jack based on the thrust T and opening pressure P.

[0085] According to one embodiment of the present invention, the cylinder diameter D required for the articulated jack is calculated according to the thrust T and the opening pressure P, including:

[0086] Take 4 times the thrust as the second product value;

[0087] Multiply the opening pressure P by the circumference ratio π to obtain the third product value;

[0088] Dividing the second product value by the third product value to obtain a second quotient value;

[0089] The value obtained by taking the square root of the second quotient is used as the cylinder diameter D.

[0090] According to the above description, the formula of the cylinder diameter D can be described as the following formula (10):

[0091]

[0092] In summary, according to the method for calculating the cylinder diameter of the articulated jack according to the embodiment of the present invention, the support force F of the top beam, the first horizontal distance l1 from the position point of the support force F to the origin of the coordinate system, and the initial top beam load distribution curve containing unknown parameters are first determined, and the vertical distance h from the hinge point to the center line of the articulated jack and the second horizontal distance L from the origin of the coordinate system to the hinge point are obtained.
