Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0053] As Figure 1 and Figure 2As shown, the present application provides a kind of intelligent vehicle drum steel wire rope tension control test device, including rear support plate 1 and vertical line storage component 2 being installed on rear support plate 1, and horizontal line storage component 3 being installed in vertical line storage component 2, and the two ends of vertical line storage component 2 and horizontal line storage component 3 are respectively equipped with wire rope tension roller 4, steel wire rope is sequentially passed through the two wire rope tension rollers 4 of vertical line storage component 2 and the two wire rope tension rollers 4 of horizontal line storage component 3.

[0054] Each wire rope tension roller 4 is equipped with clamping assembly 6, and clamping assembly 6 is used to fix steel wire rope on the contact point of wire rope tension roller 4, and clamping assembly 6 is used to fix the steel wire rope of wire rope tension roller 4 on vertical line storage component 2 and the steel wire rope of wire rope tension roller 4 on horizontal line storage component 3, and rear support plate 1 is equipped with tension measuring instrument 5 at the position of steel wire rope between every two wire rope tension rollers 4.

[0055] After the two ends of steel wire rope on wire rope tension roller 4 of vertical line storage component 2 and horizontal line storage component 3 are fixed, the distance between the two wire rope tension rollers 4 on vertical line storage component 2 and the distance between the two wire rope tension rollers 4 on horizontal line storage component 3 are adjusted to control the tension of steel wire rope between the two wire rope tension rollers 4 on horizontal line storage component 3 and vertical line storage component 2 and the tension of steel wire rope between the adjacent two wire rope tension rollers 4 on vertical line storage component 2 and horizontal line storage component 3.

[0056] In the embodiment, the vertical line storage component 2 and horizontal line storage component 3 of cross intersection are arranged, the steel wire rope is sequentially passed through the two wire rope tension rollers 4 of vertical line storage component 2 and the two wire rope tension rollers 4 of horizontal line storage component 3, and after the clamping assembly 6 on the two wire rope tension rollers 4 of vertical line storage component 2 fixes the steel wire rope, a vertical direction to be detected steel wire rope section is formed, after the clamping assembly 6 on the two wire rope tension rollers 4 of horizontal line storage component 3 fixes the steel wire rope, a horizontal direction to be detected steel wire rope section is formed, and an inclined direction to be detected steel wire rope section is formed between the adjacent two wire rope tension rollers 4 on vertical line storage component 2 and horizontal line storage component 3.

[0057] When the distance between the two wire rope tension rollers 4 on vertical line storage component 2 is adjusted, the stretching amount change of vertical direction to be detected steel wire rope section in the process of continuous pressure can be changed, similarly, when the distance between the two wire rope tension rollers 4 on horizontal line storage component 3 is adjusted, the stretching amount change of horizontal direction to be detected steel wire rope section in the process of continuous pressure can be changed, and when the distance between the two wire rope tension rollers 4 on vertical line storage component 2 and the distance between the two wire rope tension rollers 4 on horizontal line storage component 3 are adjusted simultaneously, the stretching amount change of inclined direction to be detected steel wire rope section in the process of continuous pressure can be changed.

[0058] The tensile transient tension and the tensile critical tension corresponding to the steel wire rope segment to be detected in the vertical direction, the steel wire rope segment to be detected in the horizontal direction and the steel wire rope segment to be detected in the inclined direction are combined, the tensile change relationship between the pressurized load and the tensile tension of the steel wire rope to be detected is analyzed, the dynamic deformation degree of the steel wire rope to be detected is analyzed according to the tensile change relationship, the static deformation degree under the constant pressure is combined, the rope tension control model for analyzing the tensile tension of the steel wire rope to be detected is constructed, and then the tension of the steel wire rope segment to be detected in the current horizontal direction, the steel wire rope segment to be detected in the vertical direction and the steel wire rope segment to be detected in the inclined direction at this moment is determined in combination with the rope tension control model, the distance change between the two wire tension rollers 4 on the current vertical wire storage assembly 2 and the distance change between the two wire tension rollers 4 on the current horizontal wire storage assembly 3.

[0059] Therefore, in the single test process, the test data between the linear tensile amount and the tensile tension of two groups of linear state steel wire rope segments to be detected and the test data between the inclined tensile amount and the tensile tension of one group of inclined state steel wire rope segments to be detected can be obtained at the same time, and the implementation is simple.

[0060] As shown in the figure, Figure 3 The vertical wire storage assembly 2 includes a first limiting mounting plate 21 movably mounted on the rear supporting plate 1, and a first sliding base 22 mounted at both ends of the first limiting mounting plate 21, and the wire tension roller 4 is mounted on the first sliding base 22, and the first sliding base 22 moves vertically along the first limiting mounting plate 21 under the limiting action of the first limiting mounting plate 21.

[0061] The inner side of the first sliding base 22 is provided with a vibration driving assembly 7, which is used to drive the two wire tension rollers 4 to approach or move away from each other, so as to adjust the tension of the steel wire rope between the two wire tension rollers 4 on the vertical wire storage assembly 2.

[0062] The horizontal wire storage assembly 3 includes a second limiting mounting plate 31 arranged on both sides of the first limiting mounting plate 21, and a second sliding base 32 mounted at both ends of the second limiting mounting plate 31, and the second sliding base 32 moves horizontally along the second limiting mounting plate 31 under the limiting action of the second limiting mounting plate 31.

[0063] The inner side of the second sliding base 32 is also provided with a vibration driving assembly 7, which is used to drive the two wire tension rollers 4 to approach or move away from each other, so as to adjust the tension of the steel wire rope between the two wire tension rollers 4 on the horizontal wire storage assembly 3.

[0064] The vibration driving assembly 7 includes a driving motor 71 arranged on the inner side of the wire tension roller 4, and an eccentric wheel 72 connected with the output shaft of the driving motor 71, and the other end of the eccentric wheel 72 is connected with the first sliding base 22 and the second sliding base 32 respectively.

[0065] The driving motor 71 rotates to drive the first sliding base 22 to move along the first limiting installation plate 21 through the eccentric wheel 72, so as to drive the two wire rope tension rollers 4 on the first limiting installation plate 21 to move close to or away from each other. The driving motor 71 rotates to drive the second sliding base 32 to move along the second limiting installation plate 31 through the eccentric wheel 72, so as to drive the two wire rope tension rollers 4 on the second limiting installation plate 31 to move close to or away from each other.

[0066] In order to obtain the test data between the linear stretching amount and the stretching tension of the steel wire rope segment to be detected, the two wire rope tension rollers 4 on the vertical wire storage assembly 2 are adjusted to the closest state, the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 are adjusted to the closest state, and then the steel wire rope is wound around the two wire rope tension rollers 4 on the vertical wire storage assembly 2 and the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 in sequence. After the steel wire rope is fixed, three steel wire rope segments to be detected are formed. After adjusting the two wire rope tension rollers 4 on the vertical wire storage assembly 2 and the two wire rope tension rollers 4 on the horizontal wire storage assembly 3 to move away from each other, the test data between the linear stretching amount and the stretching tension of the steel wire rope segment to be detected, and the test data between the oblique stretching amount and the stretching tension of the steel wire rope segment to be detected can be obtained.

[0067] The wire rope tension rollers 4 on the vertical wire storage assembly 2 and the wire rope tension rollers 4 on the horizontal wire storage assembly 3 are in the same vertical plane. The wire rope tension rollers 4 are provided with annular grooves 41 in a circular distribution on the side curved surface. The steel wire rope is wound around the annular grooves 41 of the wire rope tension rollers 4 on the vertical wire storage assembly 2 and the wire rope tension rollers 4 on the horizontal wire storage assembly 3 in sequence.

[0068] The side edge of the wire rope tension roller 4 is provided with a sunken groove 42. The clamping assembly 6 is installed in the sunken groove 42. The steel wire rope passes through the clamping assembly 6 and is clamped and fixed.

[0069] As shown in Figures 4 to 7 It needs to be particularly pointed out that when determining the relationship between the stretching amount and the stretching tension of the steel wire rope, the embodiment specifically divides the steel wire rope wound on the tension control test device into three segments by using the clamping assembly 6. The stretching load received by the horizontal steel wire rope segment and the vertical steel wire rope segment does not affect each other. Therefore, when obtaining the test data between the linear stretching amount and the stretching tension of the two groups of straight line state steel wire rope segments to be detected at the same time, the test data between the linear stretching amount and the stretching tension of the two groups of straight line state steel wire rope segments to be detected does not affect each other, and the accuracy of the measurement data is improved.

[0070] In addition, two wire tension rollers of the vertical wire storage assembly and two wire tension rollers of the horizontal wire storage assembly naturally cause the stretching work on the obliquely distributed steel wire rope segment to be detected during the movement, and can verify whether the stretching change relationship between the oblique stretching amount and the stretching tension of the obliquely distributed steel wire rope segment to be detected is the same as the stretching change relationship between the straight line stretching amount and the stretching tension.

[0071] The clamping assembly 6 includes an outer through sleeve 61 mounted in the sunken groove 42, and an inner rotating block 62 arranged in the inner cavity of the outer through sleeve 61, the inner rotating block 62 rotates forward and reversely under the rotation driving assembly 68, the central positions of the outer through sleeve 61 and the inner rotating block 62 are provided with through holes 63, the clamping assembly 6 is mounted in the sunken groove 42, and the hole grooves of the through holes 63 coincide with the hole grooves of the annular rope groove 41.

[0072] The side surface of the inner rotating block 62 is provided with a plurality of inner tangent grooves 64 which are uniformly distributed and in an inclined state, a fixed clamping angle is formed between the outer end of each inner tangent groove 64 and the outer tangent line of the inner rotating block 62, and the same side surface of the outer through sleeve 61 is provided with a limiting groove 65, the clamping rod 66 is mounted in the limiting groove 65, and the lower surface of the clamping rod 66 is provided with a clamping seat 67 in the inner tangent groove 64, and the inner rotating block 62 drives the clamping rod 66 to move synchronously in and out when rotating forward and reversely.

[0073] The rotation driving assembly 68 includes a cylindrical curved surface plate 681 arranged on the other side surface of the inner rotating block 62, and an oblique tooth groove 682 arranged on the side curved surface of the cylindrical curved surface plate 681.

[0074] The same side surface of the outer through sleeve 61 is provided with an oblique gear 683 engaged with the oblique tooth groove 682, and the side curved surface of the outer through sleeve 61 is provided with a servo motor 684 connected with the oblique gear 683.

[0075] The servo motor 684 drives the inner rotating block 62 to rotate forward and reversely through the engagement of the oblique gear 683 and the oblique tooth groove 682, and the inner rotating block 62 drives the clamping rod 66 to move in and out when rotating forward and reversely, so as to clamp and fix the steel wire rope in the through hole 63 or release the steel wire rope.

[0076] In the embodiment, the clamping rod 66 is mounted in the inner tangent groove 64 of the inner rotating block 62 through the clamping seat 67, and can move along the inner tangent groove 64, therefore, when the servo motor 684 drives the inner rotating block 62 to rotate forward through the engagement of the oblique gear 683 and the oblique tooth groove 682, the clamping rod 66 moves towards the through hole 63 under the driving of the inner tangent groove 64, so as to clamp and fix the steel wire rope in the through hole 63.

[0077] When the servo motor 684 drives the inner rotating block 62 to rotate reversely through the engagement of the oblique gear 683 and the oblique tooth groove 682, the clamping rod 66 moves outward under the driving of the inner tangent groove 64, so as to release the steel wire rope in the through hole 63.

[0078] In the embodiment, when the number of clamping rods 66 is sufficient, multi-point clamping and fixing of the steel wire rope can be achieved, and the clamping stability of the steel wire rope is ensured.

[0081] In step 200, the clamping assembly on the wire rope tension roller at both ends of the vertical wire storage assembly and the horizontal wire storage assembly is controlled to work, so as to clamp and fix the steel wire rope between every two wire rope tension rollers.

[0082] In step 300, the vibration driving assembly on the vertical wire storage assembly and the vibration driving assembly on the horizontal wire storage assembly are simultaneously driven to work, and the steel wire rope between the two wire rope tension rollers on the vertical wire storage assembly and the steel wire rope between the two wire rope tension rollers on the horizontal wire storage assembly are simultaneously stretched.

[0083] In step 400, the linear stretching amount of the steel wire rope between the two wire rope tension rollers on the vertical wire storage assembly and the linear stretching amount of the steel wire rope between the two wire rope tension rollers on the horizontal wire storage assembly are calculated based on the driving angle of the vibration driving assembly, and the stretching transient tension and the stretching critical tension of the to-be-tested rope are obtained by the tension measuring instrument.

[0084] In step 500, the oblique stretching amount of the steel wire rope between one wire rope tension roller of the vertical wire storage assembly and one wire rope tension roller of the horizontal wire storage assembly is calculated based on the driving angle of the vibration driving assembly, and the stretching transient tension and the stretching critical tension of the to-be-tested rope are obtained by the tension measuring instrument.

[0085] In step 600, a new steel wire rope section is replaced, and the above steps 100-500 are repeated to analyze the stretching change relationship between the linear stretching amount and the stretching tension of the to-be-tested steel wire rope, analyze the stretching change relationship between the oblique stretching amount and the stretching tension of the to-be-tested steel wire rope, construct a rope tension control model, and automatically control the tension of the steel wire rope by adjusting the driving angle of the vibration driving assembly.

[0086] In step 100, the length of the steel wire rope between the two wire rope tension rollers of the vertical wire storage assembly is the same as the length of the steel wire rope between the two wire rope tension rollers of the horizontal wire storage assembly, so that the influencing factors of the test data between the linear stretching amount and the stretching tension of the to-be-tested steel wire rope section in the two groups of linear states are the same, and the accuracy of the test data is improved.

[0087] In step 200, after the clamping assembly clamps the steel wire rope between every two wire rope tension rollers, the whole steel wire rope is divided into a to-be-tested steel wire rope segment between the two wire rope tension rollers of the vertical wire storage assembly, a to-be-tested steel wire rope segment between the two wire rope tension rollers of the horizontal wire storage assembly, and a to-be-tested steel wire rope segment between the two wire rope tension rollers on the vertical wire storage assembly and the horizontal wire storage assembly;

[0088] Wherein, when the stretching amount and the stretching tension of the to-be-tested steel wire rope segment between the two wire rope tension rollers of the vertical wire storage assembly and the to-be-tested steel wire rope segment between the two wire rope tension rollers of the horizontal wire storage assembly are calculated, each to-be-tested steel wire rope segment is independent and does not affect each other, so as to improve the accuracy of the test data between the linear stretching amount and the stretching tension of the two groups of to-be-tested steel wire rope segments in the linear state.
