Description

Technical Field

[0001] The present invention relates to the technical field of bucket strength detection, and in particular to a skid loader bucket strength detection device and a detection method thereof. Background Art

[0002] For example, the publication number (CN116359021B) discloses a skid loader bucket strength tester, including a base, the bottom of the base is fixedly connected to the support legs, the base is provided with a mounting side plate, the mounting side plate is provided with a rotating frame mechanism, the rotating frame mechanism is provided with a moving block mechanism, the moving block mechanism is fixedly connected to the first hydraulic push rod, the first hydraulic push rod is fixedly connected to the pressure plate assembly, the pressure plate assembly includes a mounting frame, a fixed pressure plate, a first rotating pressure plate mechanism, a second rotating pressure plate mechanism, a driving mechanism, a first support rod mechanism, a second support rod mechanism and a linkage mechanism, and the mounting side plate is provided with a mounting fixing mechanism. The present invention can adjust the inclination angle of the fixed pressure plate, the first rotating pressure plate mechanism and the second rotating pressure plate mechanism by setting a rotating frame mechanism, so as to perform strength testing on a bucket with an inclination, and can test the strength of different buckets at different positions through the moving block mechanism. However, its structure still needs to be improved, as follows:

[0003] Due to the limitation of bucket product appearance, the bucket needs to shovel sand and gravel in actual use. During the shoveling process, the force points of the bucket change, and the pressure at various points of the bucket itself changes. The bucket may come into contact with the sand and gravel during shoveling, causing wear on the surface. The force inside the bucket is mainly the gravity of the sand and gravel themselves. Directly applying external force to the bucket may generate pressure on the contact surface of the bucket where force is applied. It may not simulate the actual work, where there is pressure between the sand and gravel on the side walls of the bucket. The test results are not close enough to the actual bucket work.

[0004] Therefore, the present application provides a skid loader bucket strength detection device and a detection method thereof to meet the needs. Summary of the invention

Two groups of fixed plates are symmetrically mounted on the top of the sliding frame, and the ends of the two groups of fixed plates are connected to a rotating table. The inner side of the fixed plate is threadedly connected to a screw.

[0009] Optionally, a movable plate is sleeved on the outer side of the screw rod, and the movable plate slides on one side of the corresponding fixed plate. The end of the movable plate is connected to a rotating table 2, and the ends of the rotating table 1 and the rotating table 2 are respectively connected to clamping claws. A crossbeam frame is connected between the two groups of fixed plates, and an arc rack is installed on one side of the crossbeam frame.

[0010] Optionally, the scooping assembly includes a fixing frame, which is installed on the inner side of the cabinet. A driving motor is installed on one side of the fixing frame, and a screw rod is connected to the output end of the driving motor.

[0016] The present application also provides another technical solution: a testing method for a skid loader bucket strength testing device, the testing method comprising the following steps:

[0017] S1. The operator first opens the cabinet door, pulls the sliding frame out of the cabinet, and hoists the bucket between the clamping claws through the hoisting equipment. Then, the operator uses a tool to drive the screw to rotate, so that the clamping claw on the movable plate side moves toward the clamping claw on the fixed plate side, and the bucket is completely clamped.

[0018] S2. Pour the test sand and gravel into the storage bucket. The test sand and gravel are extracted by the circulation pump and sprayed out from the nozzle. The sand and gravel fall onto the surface of the bucket and impact the outer surface of the bucket to test the wear resistance of the surface layer of the bucket material. Then the sand and gravel fall onto the non-porous position of the filter plate to form a sand and gravel pile.

[0019] S3, the slider is driven by the driving motor to slide on the surface of the fixed frame, and the bucket follows the slider to move toward the sand and gravel pile, shoveling the sand and gravel into the bucket.

The gear is driven by bevel gear set 1 and bevel gear set 2 to drive the electric push rod to rotate at the bottom of the mounting block. The electric push rod provides continuous extrusion force to the contact block. The contact block squeezes the sand and gravel in the bucket, so that the bucket receives the extrusion force of the internal sand and gravel, which is convenient for simulating the pressure of the sand and gravel on the bucket in actual use. The pressure value is transmitted to the control module through the pressure sensor to calculate the fatigue strength of the bucket inner wall material.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above scheme, by setting up a detection component, the mounting block is moved to multiple points, and the electric push rod drives the contact block to squeeze the sand and gravel in the bucket, simulating the pressure state in actual work. It can quickly detect the pressure state of sand and gravel on the inner wall of the bucket during the process of the contact block squeezing sand and gravel, which is convenient for operators to detect the safety limit load of the bucket product, make the test results fit the actual situation, and improve the accuracy of the test results.

[0023] By setting up the digging component and simulating the actual action of the bucket shoveling sand and gravel, we can ensure that the stress environment of the test bucket conforms to the actual situation. Through the contact and wear between the sand and gravel and the bucket surface, we can test the wear resistance of the bucket in actual work.

[0024] By setting up the installation assembly and the threaded connection between the screw and the movable plate, the movable plate drives the second rotating platform to move toward the top of the bucket on the outer wall of the fixed plate, and the second rotating platform drives the corresponding clamping claw to contact the top surface of the bucket. When the movable plate moves downward, it drives the second rotating platform to rotate, so that the contact surface of the clamping claw is tightly attached to the top contact surface of the bucket. This can adapt to the testing of buckets of different sizes and is convenient for operators to install. BRIEF DESCRIPTION OF THE DRAWINGS

Detection assembly 8, the detection assembly 8 is installed on the inner side of the cabinet 1, and the detection assembly 8 is used to detect the bucket strength.

[0045] like Figures 1 to 4 and Fig. 9As shown, the mounting assembly 5 includes a sliding frame 51, which is mounted on the inner side of the cabinet 1, and the sliding frame 51 slides on the inner side of the cabinet 1. Two groups of fixed plates 52 are symmetrically mounted on the top of the sliding frame 51, and the ends of the two groups of fixed plates 52 are connected with a rotating table 1 53. The inner side of the fixed plate 52 is threadedly connected with a screw 54, and the outer side of the screw 54 is sleeved with a movable plate 55. The movable plate 55 slides on one side of the corresponding fixed plate 52, and the end of the movable plate 55 is connected with a rotating table 2 56. The ends of the rotating table 1 53 and the rotating table 2 56 are respectively connected with clamping claws 57. A crossbeam frame 58 is connected between the two groups of fixed plates 52, and an arc rack 59 is mounted on one side of the crossbeam frame 58. The operator opens the cabinet door 2, pulls the sliding frame 51 out from the inner side of the cabinet 1, and uses a lifting device to lift the bucket to the vicinity of the sliding frame 51. When the operator Under manual traction by the operator, the bucket is located between the two sets of fixed plates 52. The operator manually rotates the rotating table 1 53 at the end of the fixed plate 52 so that the clamping claw 57 is in contact with the bottom surface of the bucket and is horizontal. Then, the end of the screw 54 is rotated, and the screw 54 is rotated at one end of the fixed plate 52. Through the threaded connection between the screw 54 and the movable plate 55, the movable plate 55 drives the rotating table 2 56 on the outer side wall of the fixed plate 52 to move toward the top of the bucket. The rotating table 2 56 drives the corresponding clamping claw 57 to contact the top surface of the bucket, so that the movable plate 55 drives the rotating table 2 56 to rotate during the downward movement, so that the contact surface of the clamping claw 57 is tightly attached to the top contact surface of the bucket, and then the sliding frame 51 is pushed back to its original position. It can adapt to buckets of different sizes for testing and is convenient for operators to install.

[0046] like Figure 2 , Figure 3 , Figure 5 and Fig. 9As shown, the scooping assembly 6 includes a fixing frame 61, which is installed on the inner side of the cabinet 1, and a driving motor 62 is installed on one side of the fixing frame 61. The output end of the driving motor 62 is connected to a screw rod 63, and the screw rod 63 is nested in the inner side of the fixing frame 61. A slider 64 is sleeved on the outer side of the screw rod 63, and a connecting plate 65 is connected to one side of the slider 64. The end of the connecting plate 65 is connected to the crossbeam frame 58, and one side of the connecting plate 65 rotates on the fixing frame 61. The operator starts the driving motor 62 through the control module 9, and the driving motor 62 drives the screw rod 63 to rotate. The slider 64 is engaged with the screw thread of the screw rod 63 on the fixing frame 6 1, (in the initial state, the shovel teeth of the bucket remain horizontal), the bucket follows the slider 64 to move toward the sand and gravel pile, and shovels the sand and gravel into the bucket. When the slider 64 continues to move toward the direction close to the crossbeam frame 58, it drives the connecting plate 65 to rotate on the fixed frame 61, so that the crossbeam frame 58 connected to the tail end of the connecting plate 65 and the fixed plate 52 rotate on the sliding bracket of the sliding frame 51, so that the loading bucket of the bucket is vertically upward. By simulating the action of shoveling sand and gravel in the actual bucket, it is ensured that the force environment of the test bucket is in line with the actual situation. At the same time, the wear resistance of the bucket in actual work can be tested through the contact and wear between the sand and gravel and the bucket surface.

[0047] like Figure 2 , Figure 3 and 6 As shown, the transmission assembly 7 includes a mounting bracket 71, which is mounted on the inner wall of the cabinet 1, and a transmission shaft 72 is nested on the inner side of the mounting bracket. The bottom of the transmission shaft 72 is connected to a bevel gear set 1 73, and the end of a bevel gear in the bevel gear set 1 73 is connected to a gear 74, and the gear 74 is meshed with the arc rack 59. The top of the transmission shaft 72 is connected to a bevel gear set 2 75, and the output end of a bevel gear in the bevel gear set 2 75 is connected to a telescopic rod 76.

[0048] By setting the transmission component 7, the arc rack 59 installed on one side of the fixed plate 52 meshes with the gear 74 during the rotation process, and the gear 74 drives the bevel gear set 1 73 to rotate. An output end of a bevel gear in the bevel gear set 1 73 transmits the bevel gear set 2 75 through the transmission shaft 72, so that a bevel gear in the bevel gear set 2 75 drives the telescopic rod 76 to rotate. Through the transmission, the telescopic rod 76 can always effectively transmit the rotation shaft 84 to avoid affecting the normal operation of the device.

[0049] like Figure 2 , Figure 3 , 7 and Figure 8As shown, the detection component 8 includes a slide rail frame 81, which is installed on the inner side of the cabinet 1. An adjusting slide rail 82 is mounted on the inner side of the slide rail frame 81. A mounting block 83 is sleeved on the slide rail frame 81. A rotating shaft 84 is connected to the inner side of the mounting block 83. One end of the rotating shaft 84 is connected to the end of a bevel gear in the bevel gear set 75. An electric push rod 85 is sleeved on the outer side of the rotating shaft 84. A contact block 86 is connected to the end of the electric push rod 85. A pressure sensor 87 is arranged on the top of the contact block 86.

[0050] By setting up the detection component 8, the telescopic rod 76 drives the rotating shaft 84 to rotate, so that the electric push rod 85 and the bucket can keep rotating synchronously, and the control module 9 controls the adjustment slide rail 82 to slide inside the slide rail frame 81, and adjusts the position of the mounting block 83 on the adjustment slide rail 82. The telescopic rod 76 provides a conductive force to the rotating shaft 84 through telescoping, and pushes the electric push rod 85 downward to press the contact block 86 toward the bucket filled with sand and gravel. The electric push rod 85 provides a continuous squeezing force to the contact block 86, and the contact block 86 squeezes the sand and gravel in the bucket, so that the bucket is subjected to the squeezing force of the internal sand and gravel, which is convenient for simulating the pressure of the sand and gravel on the bucket in actual use, and the pressure is transmitted to the control module 9 through the pressure sensor 87. The force value is used to calculate the fatigue strength of the bucket inner wall material. At the same time, after the test is completed, the operation is stopped and the above operation is repeated to dump the sand and gravel in the bucket into the cabinet 1. The operator checks whether there are cracks on the bucket surface and whether there is a break. The safe limit bearing strength of the bucket is determined by comparing the SN curve derived from the pressure sensor 87. The mounting block 83 is moved to multiple points, and the electric push rod 85 drives the contact block 86 to squeeze the sand and gravel in the bucket to simulate the pressure state in actual work. The pressure state of the sand and gravel on the inner wall of the bucket during the process of the contact block 86 squeezing the sand and gravel can be quickly detected, which is convenient for the operator to detect the safe limit bearing of the bucket product, so that the test results fit the actual situation and are more convincing.

[0051] The present application also provides another technical solution: a testing method for a skid loader bucket strength testing device, the testing method comprising the following steps:

[0052] S1. The operator first opens the cabinet door 2, pulls the sliding frame 51 out of the cabinet body 1, and hoists the bucket between the clamping claws 57 by hoisting equipment. Then, the operator uses a tool to drive the screw 54 to rotate, so that the clamping claw 57 on one side of the movable plate 55 moves toward the clamping claw 57 on the side of the fixed plate 52, and the bucket is completely clamped.

[0053] S2, pour the test sand and gravel into the storage bucket 3, the test sand and gravel are extracted by the circulation pump 10, and sprayed out from the nozzle 11, the sand and gravel fall on the surface of the bucket, and impact the outer surface of the bucket to test the wear resistance of the surface layer of the bucket material, and then the sand and gravel fall on the non-porous position of the filter plate 4 to form a sand and gravel pile;

[0054] S3, the slider 64 is driven by the driving motor 62 to slide on the surface of the fixed frame 61, and the bucket follows the slider 64 to move toward the sand and stone pile, and the sand and stones are shoveled into the bucket. When the slider 64 continues to move toward the direction close to the crossbeam frame 58, it drives the connecting plate 65 to rotate on the fixed frame 61, so that the crossbeam frame 58 connected to the tail end of the connecting plate 65 rotates together with the fixed plate 52 on the sliding bracket of the sliding frame 51, so that the loading bucket of the bucket is vertically upward;

[0055] S4. The arc rack 59 installed on one side of the fixed plate 52 meshes with the gear 74 during the rotation process. The gear 74 is driven by the bevel gear set 1 73 and the bevel gear set 2 75 to drive the electric push rod 85 to rotate at the bottom of the mounting block 83. The electric push rod 85 provides continuous squeezing force to the contact block 86. The contact block 86 squeezes the sand and gravel in the bucket, so that the bucket is subjected to the squeezing force of the internal sand and gravel, which is convenient for simulating the pressure of the sand and gravel on the bucket in actual use. The pressure value is transmitted to the control module 9 through the pressure sensor 87 to calculate the fatigue strength of the inner wall material of the bucket.

[0056] The working principle of the technical solution provided by the present invention is as follows:

[0057] The operator opens the cabinet door 2, pulls the sliding frame 51 out from the inside of the cabinet 1, and uses the lifting equipment to lift the bucket to the vicinity of the sliding frame 51. Under the manual traction of the operator, the bucket is located between the two sets of fixed plates 52. The operator manually rotates the rotating table 1 53 at the end of the fixed plate 52 so that the clamping claw 57 contacts the bottom surface of the bucket and is horizontal. Then, the end of the screw 54 is rotated. The screw 54 rotates at one end of the fixed plate 52. Through the threaded connection between the screw 54 and the movable plate 55, the movable plate 55 drives the rotating table 2 56 on the outer wall of the fixed plate 52 to move toward the top of the bucket. The rotating table 2 56 drives the corresponding clamping claw 57 to contact the top surface of the bucket, so that the movable plate 55 drives the rotating table 2 56 to rotate during the downward movement, so that the contact surface of the clamping claw 57 is tightly attached to the top contact surface of the bucket, and then the sliding frame 51 is pushed back to its original position.

[0058] The operator pours test sand and gravel into the cabinet 1, and the sand and gravel fall from the holes of the filter plate 4 into the storage bucket 3. The circulation pump 10 is started to draw the test sand and gravel through the pipeline to the top of the cabinet 1, and pour it out from the nozzle 11. The sand and gravel fall onto the surface of the bucket, impacting the outer surface of the bucket to test the wear resistance of the surface layer of the bucket material. Then the sand and gravel fall onto the non-porous position of the filter plate 4 to form a sand and gravel pile.

[0059] The operator starts the drive motor 62 through the control module 9, and the drive motor 62 drives the screw rod 63 to rotate. The slider 64 slides on the surface of the fixed frame 61 by engaging with the thread of the screw rod 63. (In the initial state, the shovel teeth of the bucket remain horizontal.) The bucket follows the slider 64 to move toward the sand and gravel pile, and shovels the sand and gravel into the bucket. When the slider 64 continues to move toward the crossbeam frame 58, it drives the connecting plate 65 to rotate on the fixed frame 61, so that the crossbeam frame 58 connected to the rear end of the connecting plate 65 rotates together with the fixed plate 52 on the sliding bracket of the sliding frame 51, so that the loading bucket of the bucket is vertically upward.

[0060] At the same time, the arc rack 59 installed on one side of the fixed plate 52 meshes with the gear 74 during the rotation process, and the gear 74 drives the bevel gear set 1 73 to rotate. The output end of a bevel gear in the bevel gear set 1 73 transmits the bevel gear set 2 75 through the transmission shaft 72, so that a bevel gear in the bevel gear set 2 75 drives the telescopic rod 76 to rotate.

[0061] The telescopic rod 76 drives the rotating shaft 84 to rotate, so that the electric push rod 85 and the bucket can keep rotating synchronously, and the control module 9 controls the adjustment slide rail 82 to slide inside the slide rail frame 81, and adjusts the position of the mounting block 83 on the adjustment slide rail 82. The telescopic rod 76 provides a conductive force to the rotating shaft 84 through telescoping, and pushes downward through the electric push rod 85, so that the contact block 86 presses down on the bucket filled with sand and gravel, and the electric push rod 85 provides a continuous extrusion force to the contact block 86. The contact block 86 squeezes the sand and gravel in the bucket, so that the bucket is subjected to the extrusion force of the internal sand and gravel, which is convenient for simulating the pressure of the sand and gravel on the bucket in actual use. The pressure value transmitted to the control module 9 through the pressure sensor 87 is used to calculate the fatigue strength of the inner wall material of the bucket. At the same time, after the detection is completed, the operation is stopped, and the above operation is repeated to dump the sand and gravel in the bucket into the cabinet 1.

8. The detection method of the skid loader bucket strength detection device according to claim 7, characterized in that: The steps include: S1. The operator first opens the cabinet door, pulls the sliding frame out of the cabinet, and hoists the bucket between the clamping claws through the hoisting equipment. Then, the operator uses a tool to drive the screw to rotate, so that the clamping claw on the movable plate side moves toward the clamping claw on the fixed plate side, and the bucket is completely clamped. S2. Pour the test sand and gravel into the storage bucket. The test sand and gravel are extracted by the circulation pump and sprayed out from the nozzle. The sand and gravel fall onto the surface of the bucket and impact the outer surface of the bucket to test the wear resistance of the surface layer of the bucket material. Then the sand and gravel fall onto the non-porous position of the filter plate to form a sand and gravel pile. S3, the slider is driven by the driving motor to slide on the surface of the fixed frame, and the bucket follows the slider to move toward the sand and gravel pile, shoveling the sand and gravel into the bucket. When the slider continues to move toward the crossbeam frame, it drives the connecting plate to rotate on the fixed frame, so that the crossbeam frame connected to the tail end of the connecting plate rotates together with the fixed plate on the sliding bracket of the sliding frame, so that the loading bucket of the bucket is vertically upward; S4.

The gear is driven by bevel gear set 1 and bevel gear set 2 to drive the electric push rod to rotate at the bottom of the mounting block. The electric push rod provides continuous extrusion force to the contact block. The contact block squeezes the sand and gravel in the bucket, so that the bucket receives the extrusion force of the internal sand and gravel, which is convenient for simulating the pressure of the sand and gravel on the bucket in actual use. The pressure value is transmitted to the control module through the pressure sensor to calculate the fatigue strength of the bucket inner wall material.
