DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0037] See also Figure 1-Figure 11 In an embodiment of the present invention, a device for detecting deformation of an excavator boom includes a detection platform 1 and a detection mechanism 2 disposed on the detection platform 1, wherein the detection mechanism 2 is used to fix one end of the boom and twist the other end of the boom to detect deformation of the boom, and further includes:

[0038] A horizontal platform 4 is slidably connected to two upright posts 5 fixed on the detection platform 1, and an upright board 3 is fixed on the detection platform 1. The horizontal platform 4 is connected to a lifting drive mechanism installed on the upright board 3, and the lifting drive mechanism is connected to a Maltese cross movement mechanism installed on the upright board 3;

[0039] A movable plate 6 is slidably disposed on the horizontal platform 4 and is movable along the length direction of the horizontal platform 4. The movable plate 6 is connected to a horizontal driving mechanism installed on the vertical plate 3, and the horizontal driving mechanism is connected to the Maltese cross movement mechanism;

[0040] A rotating roller 23 and a fastener 24, wherein two rotating rollers 23 are provided on the horizontal platform 4, and two fasteners 24 are provided on the movable plate 6, and each of the two rotating rollers 23 and the two fasteners 24 is connected with a set of linkage mechanisms, and the linkage mechanisms are connected with an elastic driving mechanism provided on the horizontal platform 4;

[0041] Among them, the elastic driving mechanism can cause the two rotating rollers 23 to approach or move away from each other, and cause the two fasteners 24 to approach or move away from each other through the linkage mechanism, so as to perform a clamping or releasing action on the boom to be tested, and the horizontal driving mechanism can drive the movable plate 6 to move along the length direction of the horizontal platform 4, so as to cause the boom to transition to the detection mechanism 2.

[0042] Furthermore, the detection mechanism 2 is an application of the prior art, which is not elaborated in this application. It includes a guide plate 201 and a receiving plate 202 slidably connected to the guide plate 201, a tooth plate 203 is fixed to one side of the receiving plate 202, and the tooth plate 203 is equipped with two sets of driving gears 205, and is also provided with a hydraulic clamp 208 for fixing one end of the boom and a hydraulic turntable 209 for twisting the other end of the boom.

[0043] In a specific implementation, the device is placed at the tail end of the boom transmission line, and the transmission line transmits the boom to be tested. When a part of the boom is separated from the transmission belt (that is, the end of the boom separated from the transmission belt passes over the fastener 24 in the horizontal direction), the Maltese cross movement mechanism works;

[0044] Initially, the Maltese cross movement mechanism drives the lifting drive mechanism to move, and the lifting drive mechanism drives the horizontal platform 4 to slide upward on the two uprights 5 until the rotating roller 23 and the fastener 24 are flush with the boom, and after the rotating roller 23 and the fastener 24 reach the end of the rise, the elastic drive mechanism is triggered, and the two rotating rollers 23 and the two fasteners 24 are driven to approach each other through the linkage mechanism, and then the boom is clamped and fixed;

[0045] Subsequently, the Maltese cross movement mechanism drives the horizontal driving mechanism to move, and the horizontal driving mechanism drives the movable plate 6 to move along the length direction of the horizontal platform 4, and the fastener 24 moves away from the rotating roller 23, so that the boom is pulled out of the transmission line, and the Maltese cross movement mechanism drives the lifting driving mechanism to move again, and the lifting driving mechanism drives the horizontal platform 4 to descend. When the horizontal platform 4 is about to reach the end of the descent, the driving gear 205 rotates, and it can drive the receiving plate 202 to move to the top of the horizontal platform 4 through the tooth plate 203. When the horizontal platform 4 reaches the end of the descent, the elastic driving mechanism is triggered, so that the two rotating rollers 23 move away from each other, and the two fasteners 24 move away from each other, and the boom is released and placed on the receiving plate 202;

[0046] Then, the Maltese cross movement mechanism drives the horizontal driving mechanism to move, and the horizontal driving mechanism drives the movable plate 6 to slide back on the horizontal platform 4 to reset, and the fastener 24 moves close to the rotating roller 23. At the same time, the driving gear 205 changes the direction and drives the receiving plate 202 to slide on the guide plate 201 until the boom reaches the bottom of the hydraulic clamp 208. Then, the detection process can begin, and the hydraulic cylinder 206 drives the assembly plate 207 to descend, and the hydraulic clamp 208 The boom is clamped, and the assembly plate 207 rises again, so that the end of the boom corresponds to the hydraulic turntable 209. The clamping claws 204 on the hydraulic turntable 209 clamp the end of the boom, so that one end of the boom is fixed and the other end is twisted. The deformation of the boom is observed by the detection probe, and the observation results are converted into specific data and transmitted to the computer for analysis. After the detection is completed, the boom is placed on the receiving plate 202, and the receiving plate 202 continues to slide, and the boom that has completed the detection is transferred by an external transfer robot.

[0047] In summary, in a specific implementation, the Maltese cross movement mechanism can drive the lifting drive mechanism and the horizontal drive mechanism to move alternately, and at the end of the movement stroke of the lifting drive mechanism, the elastic drive mechanism can be triggered, and the boom is fixed or released through the linkage mechanism. With the coordinated cooperation of lifting, fixing and releasing, the boom to be tested on the transmission line can be transferred to the detection mechanism 2 in turn for deformation detection. Through the mutual cooperation of various mechanisms and components, the continuity detection function of the boom is realized, which can effectively improve the degree of automation of boom detection, speed up the progress of detection work, and is suitable for popularization and use.

[0048] Please refer again Figure 4 and Figure 5The Maltese cross movement mechanism includes a driving motor 8 installed on the vertical plate 3, a driving wheel 13 fixed on the output shaft of the driving motor 8, and a first driven wheel 9 and a second driven wheel 10 rotatably installed on the vertical plate 3, wherein the rotating shaft of the first driven wheel 9 is connected to the lifting drive mechanism, and the rotating shaft of the second driven wheel 10 is connected to the horizontal drive mechanism.

[0049] Please refer again Figure 5 and Figure 6 The lifting drive mechanism includes a disc 14 rotatably mounted on the vertical plate 3 and a first column 15 fixed at an eccentric position of the disc 14. A first driven rod 7 is also fixed on the movable plate 6. The first driven rod 7 is provided with a first slide groove 701 adapted to the first column 15. The first column 15 extends into the first slide groove 701 and is slidably connected to the first driven rod 7. A first transmission belt 11 is connected between the disc 14 and the rotating shaft of the first driven wheel 9.

[0050] Whenever the driving motor 8 drives the driving wheel 13 to drive the first driven wheel 9 to rotate, the rotating shaft of the first driven wheel 9 will drive the disc 14 to rotate half a circle through the first transmission belt 11, so that the first column 15 makes a circular motion and slides with the first driven rod 7 through the first slide groove 701, so that the first driven rod 7 drives the horizontal platform 4 to move upward on the two columns 5, so that the two rotating rollers 23 and the two fasteners 24 are flush with the boom, which is convenient for the subsequent clamping and fixing of the boom;

[0051] After the boom is clamped and fixed, and the fastener 24 is away from the rotating roller 23, the driving wheel 13 drives the first driven wheel 9 to rotate again, so that the disc 14 continues to rotate half a circle, and the first column 15 slides with the first driven rod 7 again, and the horizontal platform 4 descends and resets to facilitate the transfer of the boom to the detection mechanism 2.

[0052] The two groups of linkage mechanisms are the same, one group is installed on the horizontal platform 4 and connected to the two rotating rollers 23, and the other group is installed on the moving plate 6 and connected to the two fasteners 24. In this regard, the following takes a group of linkage mechanisms connected to the rotating rollers 23 as an example for a specific description:

[0053] Please refer again Figure 6 , Figure 7 as well as Figure 8The linkage mechanism includes two guide posts 20 fixedly mounted on the bottom of the horizontal platform 4 and two link plates 21 slidably connected to the two guide posts 20 and arranged opposite to each other. Two rotating rollers 23 are respectively arranged on the two link plates 21. An inclined plate 22 is respectively fixed at the bottom of the two link plates 21. The inclined plate 22 cooperates with a transmission structure arranged on the horizontal platform 4, and the transmission structure is connected to the elastic driving mechanism.

[0054] The horizontal platform 4 is provided with a first guide groove 401 and a second guide groove 402, and the first slider 25 and the second slider 26 are slidably engaged in the first guide groove 401 and the second guide groove 402 respectively. The transmission structure includes a follower rod 27 fixed to the second slider 26, a first cross arm 28 fixed to the follower rod 27, and a second cross arm 29 slidably arranged on the follower rod 27. Two driving rods 30 are fixed to the first cross arm 28 and the second cross arm 29. The inclined plate 22 is provided with a through groove 2201 adapted to the driving rod 30. The driving rod 30 penetrates the through groove 2201 and is slidably connected to the inclined plate 22. A driven plate 31 is also fixed to the end of the second slider 26 away from the follower rod 27, and the driven plate 31 cooperates with the elastic driving mechanism.

[0055] Whenever the driving motor 8 drives the driving wheel 13 to drive the second driven wheel 10 to rotate, so that the second driven wheel 10 drives the horizontal driving mechanism to move, and the movable plate 6 moves along the length direction of the horizontal platform 4, the second cross arm 29 will slide along the follower rod 27, and whenever the elastic driving mechanism is triggered, it can cooperate with the follower plate 31, so that the follower plate 31 drives the second slider 26 to slide in the second guide groove 402, so that the second slider 26 can drive the follower rod 27, the first cross arm 28, the second cross arm 29 and the four driving rods 30 to move upward or downward, and make the driving rod 30 slide and cooperate with the inclined plate 22 through the through groove 2201;

[0056] When the driving rod 30 moves upward, the two connecting plates 21 are urged to move toward each other on the two guide columns 20, the two rotating rollers 23 move toward each other, and the two fasteners 24 also move toward each other to clamp the boom. Conversely, when the driving rod 30 moves downward, the two connecting plates 21 move away from each other, the two rotating rollers 23 move away from each other, and the two fasteners 24 also move away from each other to release the boom.

[0057] Please refer again Figure 8 , Fig. 9 as well as Fig.10The elastic driving mechanism includes two cylinders 33 fixedly connected to the first slider 25 and two cross bars 34 slidably fitted with the two cylinders 33 respectively. A ring body 35 fixed to the cross bar 34 is slidably provided in the cylinder 33, and a first cylindrical spring 36 and a second cylindrical spring 37 are sleeved on the outer periphery of the cross bar 34. The head ends of the first cylindrical spring 36 and the second cylindrical spring 37 are connected to the ring body 35, and the tail ends are in contact with the inner wall of the cylinder 33. The first slider 25 is also connected to a fourth column 39, one end of the two cross bars 34 is fixedly connected to a fifth column 40, the fourth column 39 and the fifth column 40 cooperate with a limiting structure provided on the detection platform 1, the other end of the two cross bars 34 is fixedly connected to a third column 38, and the driven plate 31 is provided with an inclined groove 3101 adapted to the third column 38, the third column 38 extends into the inclined groove 3101 and is slidably connected to the driven plate 31.

[0058] The limiting structure includes a vertical plate 32 fixedly mounted on the detection platform 1, and the vertical plate 32 is provided with an inclined groove body 3205 adapted to the fourth column 39 and a rectangular groove body adapted to the fifth column 40, and the rectangular groove body includes a first groove section 3201, a second groove section 3202, a third groove section 3203 and a fourth groove section 3204 connected to each other.

[0059] At first, the fifth column 40 is located at the intersection of the first slot section 3201 and the fourth slot section 3204. When the horizontal platform 4 is rising, the fourth column 39 slides along the inclined slot 3205. At this time, the fifth column 40 slides upward along the first slot section 3201, so that the fourth column 39 slides with the vertical plate 32 through the inclined slot 3205, and the cylinder 33 gives way, so that the first slider 25 slides to one side in the first guide slot 401, and the first column spring 36 is compressed. When the horizontal platform 4 rises to the end of the stroke, the fifth column 40 moves to the intersection of the first slot section 3201 and the second slot section 3202, so that the first The cylindrical spring 36 rebounds, so that the cross bar 34 slides on the cylinder 33, and the fifth column 40 moves along the second slot section 3202 to the intersection of the second slot section 3202 and the third slot section 3203. Specifically, the cross bar 34 drives the third column 38 to slide in the inclined groove 3101, and the third column 38 and the driven plate 31 are slidably matched, so that the driven plate 31 drives the second slider 26 to slide upward in the second guide groove 402, and then, the driving rod 30 can slide with the inclined plate 22 through the through groove 2201, so that the two rotating rollers 23 are close to each other, and the two fasteners 24 are close to each other, so as to fix the bucket arm to be detected;

[0060] When the horizontal platform 4 is descending, the fifth column 40 moves downward along the third slot section 3203, and the fourth column 39 slides with the vertical plate 32 again through the inclined slot body 3205, so that the cylinder 33 gives way and the second column spring 37 is compressed. After the descending process of the horizontal platform 4 is completed, the fifth column 40 moves to the intersection of the third slot section 3203 and the fourth slot section 3204, and the second column spring 37 rebounds. The fifth column 40 is transferred along the fourth slot section 3204 to the intersection of the fourth slot section 3204 and the first slot section 3201. At the same time, the cross bar 34 drives the third column 38 to slide with the driven plate 31 again, so that the driven plate 31 moves downward, the two rotating rollers 23 move away from each other, and the two fasteners 24 move away from each other, and the boom is released to the receiving plate 202.

[0061] It should be emphasized that in order to ensure that the coordinated action of the two rotating rollers 23 and the two fasteners 24 can reliably fix the boom and ensure the regularity of the position of the boom after the boom is transferred, the rotating rollers 23 and the fasteners 24 are provided with anti-slip elastic materials. When the boom is fixed, the elastic material is deformed. In addition, the elastic potential energy of the first columnar spring 36 and the second columnar spring 37 is large enough.

[0062] Please refer again Figure 5 and Figure 6 The horizontal driving mechanism includes two driving wheels 17 rotatably mounted on the vertical plate 3, a connecting member 18 connecting the two driving wheels 17, and a second column 19 provided on the connecting member 18. The connecting member 18 is in rolling cooperation with the two driving wheels 17, and a second transmission belt 12 is connected between the rotating shaft of one of the driving wheels 17 and the second driven wheel 10. A second driven rod 16 is also fixed to the side of the moving plate 6. A second slide groove 1601 adapted to the second column 19 is provided on the second driven rod 16. The second column 19 extends into the second slide groove 1601 and is slidably connected to the second driven rod 16.

[0063] Furthermore, the connecting member 18 forms a closed interval, which includes two relative straight line segments and two relative semi-arcs. Whenever the driving motor 8 drives the active wheel 13 to drive the second driven wheel 10 to rotate, the rotating shaft of the second driven wheel 10 will drive the driving wheel 17 to rotate through the second transmission belt 12, so that the connecting member 18 drives the second column 19 to move. The movement trajectory of the second column 19 is consistent with the closed figure formed by the connecting member 18. Each time the second driven wheel 10 rotates, the second column 19 is transferred from the midpoint of one semi-arc to the midpoint of another semi-arc, and during the movement, it will slide and cooperate with the second driven rod 16 through the second slide groove 1601, prompting the second driven rod 16 to drive the movable plate 6 to slide along the length direction of the horizontal platform 4.
