Description

[0002] The basic performance requirements for rubber tracks are: physical properties, chemical properties, mechanical properties, environmental adaptability, size and appearance, dynamic performance, durability, safety and biocompatibility; durability is reflected in fatigue life testing of rubber tracks to evaluate the durability of rubber tracks when subjected to repeated loading and unloading, to ensure that they can maintain good performance after long-term use.

[0003] In the prior art, due to the lack of specific rubber track testing equipment, the rubber track can only be installed on a special track testing vehicle, and then the special track testing vehicle is used to perform fatigue life tests on the rubber track. This requires manual work to continuously follow the special track testing vehicle to record the test data and results of the rubber track, which not only takes a lot of time but also requires a larger activity area. In addition, the special track testing vehicle cannot continuously and uninterruptedly test the rubber track, which further prolongs the test time of the rubber track, thereby increasing the test cost of the rubber track.

[0043] The tensioning mechanism includes an L-shaped plate 101, a traveling frame 102, a driving wheel 103, a guide wheel 104, a supporting roller 105, an electric push rod 106 and a tensioning wheel 107; the lower part of the connecting shaft 8 is fixedly connected to the L-shaped plate 101; the lower part of the L-shaped plate 101 is fixedly connected to the traveling frame 102; the left part of the traveling frame 102 is rotatably connected to the driving wheel 103, and the driving wheel 103 is rotatably connected to the L-shaped plate 101; the right part of the traveling frame 102 is rotatably connected to the guide wheel 104; the lower part of the traveling frame 102 is rotatably connected to a plurality of supporting rollers 105; the rear side surface of the L-shaped plate 101 is bolted with an electric push rod 106; a slide groove 10101 is opened on the L-shaped plate 101; the tensioning wheel 107 is slidably connected to the slide groove 10101; the telescopic part of the electric push rod 106 is fixedly connected to the tensioning wheel 107.

[0044] The power mechanism includes a stepper motor 201, a transmission wheel 1 202 and a transmission wheel 2 203; the stepper motor 201 is bolted to the left of the L-shaped plate 101; the output shaft of the stepper motor 201 passes through the L-shaped plate 101, and the transmission wheel 1 202 is fixedly connected to the output shaft of the stepper motor 201; the transmission wheel 2 203 is fixedly connected to the rotating shaft of the driving wheel 103; the outer ring surface of the transmission wheel 1 202 is connected to the transmission wheel 2 203 through a belt.

[0045] The load-bearing mechanism includes a hydraulic cylinder 301 and a circular pressing block 302 ; the hydraulic cylinder 301 is bolted to the lower surface of the connecting plate 4 ; and the circular pressing block 302 is fixed to the telescopic portion of the hydraulic cylinder 301 .

[0046] The circular pressing block 302 is made of metal, and the lower surface of the circular pressing block 302 is a smooth layer.

[0047] The working steps of this embodiment are:

[0048] The following rotations are from front to back, from top to bottom, and from right to left.

[0049] The first step is to place the performance detection device for the rubber track 12 at a desired position when in use;

[0050] In the second step, the operator connects an external power supply to all components that need to be driven by electricity, puts the rubber track 12 on the driving wheel 103, the guide wheel 104, the supporting wheel 105 and the tensioning wheel 107, and then controls the telescopic part of the electric push rod 106 to push out, and the tensioning wheel 107 moves upward in the slide groove 10101, driving the rubber track 12 to extend upward, forcing the rubber track 12 to be tightened. Figure 7 As shown, the electric slider 3 is then controlled to move backward on the electric slide rail 2, and the two electric sliders 3 drive the connecting plate 4, the slide bar 5, the shock absorbing spring 6, the fixing plate 7, the connecting shaft 8, the tensioning mechanism, the power mechanism, the load-bearing mechanism and the rubber crawler 12 to move backward together. After the electric slider 3 moves to the middle of the electric slide rail 2, the two electric sliders 3 are controlled to stop moving, and at this time, the rubber crawler 12 is located in the middle of the conveyor belt 11;

[0051] In the third step, due to the lack of a specific test device for the rubber track 12, the rubber track 12 can only be installed on a special track test vehicle, and then the special track test vehicle is used to perform a fatigue life test on the rubber track 12. It is necessary to manually follow the special track test vehicle to record the test data and results of the rubber track 12, which not only takes a lot of time and manpower, but also requires a larger activity area. Therefore, when the rubber track 12 moves to the middle of the conveyor belt 11, the telescopic part of the hydraulic cylinder 301 is controlled to be pushed out, driving the circular pressing block 302 to move downward. The circular pressure block 302 is moved to contact the connecting shaft 8. After the circular pressure block 302 contacts the connecting shaft 8, it will push the slide bar 5, the fixing plate 7, the connecting shaft 8, the tensioning mechanism, the power mechanism and the rubber crawler 12 to move downward together, forcing the two shock-absorbing springs 6 to be compressed. After the rubber crawler 12 contacts the conveyor belt 11, the telescopic part of the hydraulic cylinder 301 is controlled to stop moving. At this time, the inner annular surface of the conveyor belt 11 is fitted with the bracket 9, and the conveyor belt 11 is supported by the bracket 9 to avoid the load applied downward by the rubber crawler 12, which causes the conveyor belt 11 to deform.

[0052] When the rubber crawler 12 contacts the conveyor belt 11, the output shaft of the stepper motor 201 is controlled to drive the transmission wheel 1 202 to rotate clockwise, and the transmission wheel 1 202 drives the transmission wheel 2 203 to rotate clockwise through the belt, and the transmission wheel 2 203 drives the driving wheel 103 to rotate clockwise, and the driving wheel 103 drives the rubber crawler 12 to be transported clockwise on the transmission mechanism. As the rubber crawler 12 runs clockwise, it will drive the conveyor belt 11 and the two conveyor rollers 10 to rotate counterclockwise, so that the conveyor belt 11 continues to run counterclockwise;

[0053] At the same time, fatigue life test of the rubber track 12 requires repeated loading and unloading of the rubber track 12 to evaluate the life of the rubber track 12 under fatigue conditions, and the loading of the rubber track 12 can be achieved by controlling the telescopic portion of the hydraulic cylinder 301 to push out, and applying a certain load to the rubber track 12 during operation (the load applied to the rubber track 12 is set according to the load limit of the rubber track 12 actually used), simulating the pressure on the rubber track 12 during operation, and unloading of the rubber track 12, after the loading of the rubber track 12 is completed, by controlling the telescopic portion of the hydraulic cylinder 301 to contract, the applied load will be gradually reduced until it disappears, simulating the process of the rubber track 12 transitioning from a load-bearing state to a non-load-bearing state in actual use, in this way. The loading and unloading process will be repeated continuously to form a complete stress cycle. Each cycle represents a load change process experienced by the track in actual use, until the operator observes any phenomenon such as cracks, fractures, degumming and deformation of the rubber track 12, indicating that the performance of the rubber track 12 has obviously degraded or is damaged, and then the test of the rubber track 12 is stopped. During the test, the number of cycles that the rubber track 12 can withstand will be recorded, and the life of the rubber track 12 under fatigue conditions will be obtained. In this way, the rubber track 12 can be tested continuously, and the test data and results of the rubber track 12 can be obtained in a short time, which not only saves a lot of time and manpower, but also does not need to find a larger activity venue, further reducing the testing cost of the rubber track 12.

[0054] The fourth step, when the test is completed, the output shaft of the stepper motor 201 is controlled to stop rotating, the rubber track 12 and the conveyor belt 11 stop running, the telescopic part of the hydraulic cylinder 301 contracts, and the connected parts are driven to reset upwards, and the connecting shaft 8 is no longer squeezed. Under the action of the two shock-absorbing springs 6, the slide bar 5, the fixed plate 7, the connecting shaft 8, the tensioning mechanism, the power mechanism and the rubber track 12 automatically move upwards, and the rubber track 12 does not contact the conveyor belt 11. Then the two electric sliders 3 are controlled to drive the connected parts to move forward, and the electric slider 3 is moved to the front. The telescopic part of the electric push rod 106 is controlled to contract, and the connected parts are driven to move downward, and the rubber track 12 is no longer restricted. The operator removes the tested rubber track 12 from the driving wheel 103, the guide wheel 104, the supporting wheel 105 and the tensioning wheel 107.

[0055] Example 2

[0056] On the basis of Example 1, Figure 1-Figure 5 As shown, it also includes a laying mechanism, and the right part of the support frame 1 is connected to the laying mechanism; the laying mechanism includes a mounting frame 401, a collection box 402, a partition 403, a cross plate 1 404, a servo motor 1 405, a cross plate 2 406 and a servo motor 2 407; the right middle part of the support frame 1 is fixedly connected to the mounting frame 401; the collection box 402 is fixedly connected to the mounting frame 401; the partition 403 is fixedly connected to the collection box 402, and the space of the collection box 402 is separated by the partition 403 It is composed of a storage slot 1 40201 and a storage slot 2 40202; a cross plate 1 404 is rotatably connected in the storage slot 1 40201; a servo motor 1 405 is bolted to the front side of the partition 403; the output shaft of the servo motor 1 405 is fixedly connected to the cross plate 1 404; a cross plate 2 406 is rotatably connected in the storage slot 2 40202; a servo motor 2 407 is bolted to the front side of the partition 403; the output shaft of the servo motor 2 407 is fixedly connected to the cross plate 2 406.

[0057] The laying mechanism also includes a guide plate 408 and a conveyor 409; the guide plate 408 is fixedly connected to the lower left part of the support frame 1, and the guide plate 408 is located on the left side of the conveyor belt 11; the conveyor 409 is arranged on the inner side of the bracket 9, and the conveyor 409 is located below the guide plate 408.

[0058] The working principle of this embodiment is:

[0059] The operator connects an external power supply to all parts that need to be driven by electricity, places gravel in storage tank 1 40201, places nails or sharp metal objects in storage tank 2 40202, and places a storage box at the right end of the conveyor 409. Since the rubber track 12 is widely used in muddy and mountainous areas, and both muddy and mountainous areas contain a large number of sharp stones and a small number of nails or sharp metal objects, it is easy to cause puncture to the rubber track 12, resulting in damage to the rubber track 12. Therefore, it is necessary to test the rubber track 12 for resistance to puncture by sharp objects. Therefore, during the continuous operation of the rubber track 12, the telescopic part of the hydraulic cylinder 301 is controlled to be pushed out, driving the connected parts to move downward, and applying pressure to the rubber track 12. Load the rubber crawler 12, put it in working state, and then control the output shaft of the servo motor 405 to rotate counterclockwise, drive the cross plate 404 to rotate counterclockwise, and gradually place the gravel in the storage tank 40201 on the conveyor belt 11 through the cross plate 404, and move to the left by the continuously running conveyor belt 11, and then the continuously running rubber crawler 12 will roll on the gravel on the conveyor belt 11 to test the anti-sharp object puncture performance of the rubber crawler 12 running on the gravel road surface. After the rubber crawler 12 runs for a period of time, control all parts to reset, and the operator removes the rubber crawler 12, observes and detects the rubber crawler 12, and obtains the test data and results of the rubber crawler 12;

[0060] When the rubber track 12 is continuously running and the cross plate 1 404 is continuously placing gravel on the conveyor belt 11, the output shaft of the servo motor 2 407 is controlled to rotate counterclockwise, driving the cross plate 2 406 to rotate counterclockwise, and intermittently placing nails or sharp metal objects on the conveyor belt 11, so that the nails or sharp metal objects are mixed with the gravel and conveyed to the left under the continuous action of the conveyor belt 11, and then the rubber track 12 will roll over the nails or sharp metal objects and gravel on the conveyor belt 11 to test the rubber track 12's anti-sharp object puncture performance when running on a road surface mixed with gravel and nails or sharp metal objects. After the rubber track 12 has been running for a period of time, all components are controlled to reset, and the operator removes the rubber track 12, observes and inspects the rubber track 12, and obtains the test data and results of the rubber track 12.

[0061] It should be noted that as the rubber track 12 continues to run, the gravel, nails or sharp metal objects crushed by the rubber track 12 will fall from the left part of the conveyor belt 11 onto the guide plate 408 under the drive of the conveyor belt 11, and then fall onto the conveyor 409 along the guidance of the guide plate 408. The conveyor 409 is controlled to run, and the gravel, nails or sharp metal objects that fall on the conveyor 409 are transported to the right and enter the storage box at the right end of the conveyor 409. Then the operator needs to regularly pour the gravel, nails or sharp metal objects in the storage box into the storage slot 1 40201 and the storage slot 2 40202 to ensure that the gravel, nails or sharp metal objects in the storage slot 1 40201 and the storage slot 2 40202 can be continuously placed on the conveyor belt 11.

[0062] It should be noted that storage tank 1 40201 and storage tank 2 40202 can contain not only gravel but also sand, soil, branches, etc., which can be matched with each other when needed to simulate the environment of sand, mud and mountains, so as to facilitate various performance tests of the rubber track 12.

[0063] Example 3

[0064] On the basis of Example 2, Figure 3 As shown, it also includes a rotating mechanism, which is connected to the fixed plate 17 and the connecting shaft 8; the rotating mechanism includes a servo motor 3 501, a spur gear 1 502 and a spur gear 2 503; the upper surface of the fixed plate 17 is bolted with the servo motor 3 501; the output shaft of the servo motor 3 501 is fixedly connected with the spur gear 1 502; the lower part of the connecting shaft 8 is fixedly connected with the spur gear 2 503, and the spur gear 2 503 is located between the fixed plate 17 and the L-shaped plate 101; the fixed plate 17 is rotatably connected to the connecting shaft 8.

[0065] The working principle of this embodiment is:

[0066] The operator connects an external power supply to all parts that need to be powered by electricity. In the prior art, since the rubber track 12 can not only move forward and backward but also rotate during use, and the friction of the rubber track 12 on the road surface during rotation is more serious than the friction on the road surface during normal walking, it is even more necessary to test the anti-sharp object puncture effect of the rubber track 12 rotating on gravel (or a mixture of gravel and nails). Therefore, during the test of the rubber track 12 for anti-sharp object puncture, when the rubber track 12 is rolled on the gravel (or a mixture of gravel and nails), the output shaft of the stepper motor 201 is controlled to stop rotating, and then the output shaft of the servo motor 3501 is controlled to stop rotating. The output shaft drives the spur gear 1 502 to rotate, and the spur gear 1 502 drives the spur gear 2 503, the connecting shaft 8, the tensioning mechanism, the power mechanism and the rubber track 12 to rotate together. The rubber track 12 will drive the pressed gravel (or a mixture of gravel and nails) to rotate together, and the rubber track 12 is subjected to a self-rotation anti-sharp object puncture test on the gravel (or a mixture of gravel and nails) road surface. After the rubber track 12 rotates for many times, all parts are controlled to reset, and the operator removes the rubber track 12, observes and detects the rubber track 12, and obtains the test data and results of the rubber track 12. At the same time, the wear resistance test of the rubber track 12 during the self-rotation process can also be performed.

[0067] Example 4

[0068] On the basis of Example 3, Figure 6-Figure 7 As shown, it also includes a detection mechanism, which is connected to the L-shaped plate 101; the detection mechanism includes a fixed plate 2 601, a camera 602, a servo motor 4 603 and a brush roller 604; the fixed plate 2 601 is fixedly connected to the middle and upper part of the L-shaped plate 101; the camera 602 is bolted to the fixed plate 2 601; the servo motor 4 603 is bolted to the rear side of the L-shaped plate 101; the right part of the L-shaped plate 101 is rotatably connected to the brush roller 604; a plurality of bristles are arranged on the outer surface of the brush roller 604; the output shaft of the servo motor 4 603 is fixedly connected to the brush roller 604.

[0069] Furthermore, in order to sweep away the gravel attached to the surface of the rubber track 12, the bristles of the brush roller 604 are distributed in a spiral shape.

[0070] The working principle of this embodiment is:

[0071] The operator connects an external power supply to all parts that need to be driven by electricity. In the prior art, after the rubber track 12 is tested for resistance to puncture by sharp objects, various scratches of varying depths will appear on the rubber track 12, and some gravel will adhere to the rubber track 12. Manual detection of the scratches on the rubber track 12 takes a long time and has low detection efficiency. Therefore, when the resistance to puncture by sharp objects of the rubber track 12 is completed and the rubber track 12 is separated from the conveyor belt 11, the camera 602 is controlled to be turned on to detect the outer surface of the rubber track 12, and then the output shaft of the stepper motor 201 is controlled to rotate clockwise to drive the connected The components and the rubber track 12 run clockwise, and at the same time, the output shaft of the servo motor 603 is controlled to rotate counterclockwise, driving the brush roller 604 to rotate together, and the bristles on the brush roller 604 clean the gravel attached to the outer surface of the rubber track 12 forward, so that it falls onto the conveyor belt 11, and the gravel on the surface of the rubber track 12 is removed, so that the camera 602 can detect the scratches on the outer surface of the rubber track 12, and then determine the puncture effect of the gravel and nails or metal sharp objects on the rubber track 12. In this way, there is no need to manually detect the scratches on the outer surface of the rubber track 12, which saves a lot of manpower and time and improves the detection efficiency.
