[0021] A method for detecting defects in oiled wood poles, the specific steps are as follows:

[0022] Step 1: Pass the wood through the top machine plate, which uses a log clamp to fix the end of the wood;

[0023] Step 2: Start the second motor and control the notch ring plate to rotate, and control all the crack detection components and scab detection components to move toward the wood together until the bottom surface of the arc hook plate and the bottom end of the detection feeler rod are in contact with the surface of the wood;

[0024] Step 3: Restart the motor three and control the notch ring plate three to rotate, so as to adjust the angles of all the connecting frames one and two, pull out the card wheel shaft and release the restriction of the winding wheel, so that the needle bar can move adaptively when encountering a crack;

[0025] Step 4: The detection frame is driven to move linearly by the track machine, and the drive track is driven by the motor 1 at the same time. The notch ring then carries the distance adjustment ring group, the crack detection component and the scab detection component to move in a circular motion around the surface of the wood at the same time, so as to detect the surface quality of the wood;

[0026] Step 5: Collect test results and address wood defects.

[0027] The technical effects achieved by the present invention are:

[0028] The present invention provides a device specially used for detecting the surface quality of oiled wood poles. All crack detection components and scab detection components move along the wood surface in a spiral manner for detection. This spiral path detection method greatly improves the range of wood surface inspection. In addition, by controlling the moving speed of the track machine and the rotation speed of the notch ring, the pitch of the spiral path can also be changed, and the detection area can be flexibly adjusted according to the actual size of the wood.

[0029] In the present invention, all the crack detection components and scab detection components can be controlled to move towards or away from the wood together, so as to detect woods with different diameter sizes, thereby expanding the application range of the detection device. Additionally, when adjusting the pitch of the spiral movement path of the detection components according to the actual size of the wood, the detection angles of the crack detection components and the scab detection components can be adjusted accordingly, and the detection range suitable for woods with different diameter sizes can be modified.

[0030] In the present invention, the crack detection components can accurately detect the cracks on the wood surface. The arc-shaped hook plate can prevent the protrusion from blocking the movement of the blocker, and the inclined needle rod can automatically move out of the crack when it detects a crack as the component moves. Additionally, the settings of the liquid storage tank, the injector, and the nozzle can automatically mark the crack when it is detected, and the marking process does not require any electronic component control, with sensitive triggering and a compact structure.

[0031] In the present invention, the scab detection components can accurately and sensitively detect the protrusions on the wood surface. Since most of the protrusions on the wood surface are the positions of diseased scabs, the scabs on the wood surface can be detected, endowing the detection device with the function of detecting other defects and further expanding the application range of the device.

[0032] In the present invention, the elastic telescopic rod III can ensure that the hard brush is closely attached to the wood surface. When the notch ring moves, the hard brush can brush off the debris attached to the wood surface in a spiral path, thereby avoiding the influence of surface foreign objects on the detection work and ensuring the authenticity and accuracy of the detection results.

Specific embodiments

[0046] In order to make the objectives and advantages of the present invention clearer, the present invention will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present invention, and does not strictly limit the scope of protection specifically claimed by the present invention.

[0047] As Figures 1 - 10As shown in the figure, an oilwood pole defect detection device includes: a ground rail 1, a round wood clamp 2, a detection frame 3, and a piece of wood 9. Two round wood clamps 2 are fixedly arranged at both ends of the ground rail 1 and are used to clamp both ends of the wood 9. The detection frame 3 is slidably assembled on the surface of the ground rail 1, and a top machine disc 301 is fixedly installed on the top of the detection frame 3. A notch ring 305 is rotatably assembled on the front of the top machine disc 301, and an adjustable distance ring group 4 is fixedly assembled on the side surface of the notch ring 305. A crack detection component 5 and a scab detection component 6 are arrayed on the inner edge of the adjustable distance ring group 4, and the crack detection component 5 and the scab detection component 6 are arranged alternately.

[0048] Embodiment 1:

[0049] Referring to the attached Figures 2 - 4 , auxiliary wheels 304 are rotatably assembled in a circular array on the front of the top machine disc 301, and the notch ring 305 is rotatably assembled on the front of the top machine disc 301 through the auxiliary wheels 304. A driving track 303 is assembled on the top of the front of the top machine disc 301 through a crawler wheel. The driving track 303 is attached to the edge surface of the notch ring 305 and is used to drive the notch ring 305 to rotate. A motor 1 302 for driving the driving track 303 is fixedly installed on the top of the back of the top machine disc 301. Screw mounting plates 306 are fixedly installed in a circular array on the front of the notch ring 305.

[0050] The working principle of the present invention is as follows: The detection frame 3 is pulled by a track machine to move along the ground rail 1. After the motor 1 302 is started, it directly drives the driving track 303 to operate, and the notch ring 305 in contact with the driving track 303 will then rotate around the wood 9. At this time, all the crack detection components 5 and the scab detection components 6 will move along the surface of the wood 9 in a spiral contact for detection. This detection method of the spiral path greatly improves the inspection range of the surface of the wood 9. Moreover, by controlling the moving speed of the track machine and the rotating speed of the notch ring 305, the pitch of the spiral path can also be changed, and the detection range can be flexibly adjusted according to the actual size of the wood 9.

[0051] Embodiment 2:

[0052] Referring to the attached Figure 5 , the adjustable distance ring group 4 is composed of a notch ring plate 1 401, a notch ring plate 2 402, and a notch ring plate 3 403. Screw hole plates 404 are integrally arranged on the back of the notch ring plate 1 401 corresponding to the positions of the screw mounting plates 306, and the screw mounting plates 306 and the corresponding screw hole plates 404 are fixedly assembled through screws 307. Straight grooves 407 are integrally arranged in a circular array on the inner side of the notch ring plate 1 401. Arc grooves 1 405 for installing the notch ring plate 2 402 and arc grooves 2 406 for installing the notch ring plate 3 403 are opened in a circular array on the front of the notch ring plate 1 401.

[0053] Referring to the attached Figures 2 - 5, on the inner side of the second notched ring plate 402, a curved groove 408 is integrally arranged in an annular array, and on one side of the outer edge of the second notched ring plate 402, a first side ring tooth 409 is integrally arranged in an array. On one side of the first motor 302, a second motor 7 is fixedly installed, and on the output shaft of the second motor 7, a first gear 701 is fixedly installed. The first gear 701 meshes with the first side ring tooth 409.

[0054] Refer to the appendix Figures 2 - 5 , on the back of the third notched ring plate 403, a second arm ring tooth 410 is arranged in an annular array, and on one side of the outer edge of the third notched ring plate 403, a second side ring tooth 411 is integrally arranged in an array. On the other side of the first motor 302, a third motor 8 is fixedly installed, and on the output shaft of the third motor 8, a second gear 801 is fixedly installed. The second gear 801 meshes with the second side ring tooth 411.

[0055] Refer to the appendix Figure 6 , the crack detection component 5 includes a first rotating mounting frame 501. One end of the first rotating mounting frame 501 is fixedly connected with a first through rod 502, and in the middle of the first through rod 502, a first rotation limiting slider 503 is integrally arranged. The first through rod 502 movably penetrates through the corresponding curved groove 408, and the first rotation limiting slider 503 is slidably assembled inside the corresponding straight groove 407. The other end of the first rotating mounting frame 501 is rotatably assembled with a first connecting frame 504. At the top of the central axis of the first connecting frame 504, a first long gear 505 is fixedly installed. The first long gear 505 meshes with the corresponding second arm ring tooth 410.

[0056] Refer to the appendix Figure 11 , the scab detection component 6 includes a second rotating mounting frame 601. One end of the second rotating mounting frame 601 is fixedly connected with a second through rod 602, and at the end of the second through rod 602, a second rotation limiting slider 603 is integrally arranged. The second through rod 602 movably penetrates through the corresponding curved groove 408, and the second rotation limiting slider 603 is slidably assembled inside the corresponding straight groove 407. The other end of the second rotating mounting frame 601 is rotatably assembled with a second connecting frame 604. At the top of the central axis of the second connecting frame 604, a second long gear 605 is fixedly installed. The second long gear 605 meshes with the corresponding second arm ring tooth 410.

[0057] According to the above structure, when it is necessary to detect woods 9 with different diameter sizes, start the second motor 7 and control the rotation of the first gear 701. Through the meshing of the first gear 701 and the first side ring tooth 409, the second notched ring plate 402 is rotated. Since both the first through rod 502 and the second through rod 602 penetrate through the corresponding curved groove 408, when the second notched ring plate 402 rotates, the distances of the first through rod 502 and the second through rod 602 from the center of the circle can be changed, and the first rotation limiting slider 503 and the second rotation limiting slider 603 will simultaneously move along the corresponding straight groove 407. During the above process, all the crack detection components 5 and scab detection components 6 can be controlled to move towards or away from the wood 9 together, thereby realizing the detection of woods 9 with different diameter sizes and expanding the application range of the detection device;

[0058] When the pitch of the detection spiral path changes, the crack detection component 5 and the scab detection component 6 also need to be adjusted, that is, the angles of the first connecting frame 504 and the second connecting frame 604 are changed. At this time, the third motor 8 needs to be started and the second gear 801 is controlled to rotate. By the meshing of the second gear 801 and the second side ring tooth 411, the third notched ring plate 403 is rotated. Since the first long gear 505 and the second long gear 605 are respectively meshed with the corresponding second arm ring teeth 410, when the third notched ring plate 403 rotates, the angles of the first connecting frame 504 and the second connecting frame 604 can be changed simultaneously. In the above process, when the pitch of the detection component's spiral movement path is adjusted according to the actual size of the wood 9, the detection angles of the crack detection component 5 and the scab detection component 6 can be adjusted accordingly, and the detection range adapted to the wood 9 with different diameter sizes can be modified.

[0059] The working principle of the present invention is as follows: When it is necessary to detect woods 9 with different diameter sizes, the second motor 7 is started and the first gear 701 is controlled to rotate. By the meshing of the first gear 701 and the first side ring tooth 409, the second notched ring plate 402 is rotated. Since the first through rod 502 and the second through rod 602 both penetrate the corresponding curved grooves 408, when the second notched ring plate 402 rotates, the distances of the first through rod 502 and the second through rod 602 from the center of the circle can be changed, and the first rotation-limiting slider 503 and the second rotation-limiting slider 603 will move along the corresponding straight grooves 407 simultaneously; when the pitch of the detection spiral path changes, the crack detection component 5 and the scab detection component 6 also need to be adjusted, that is, the angles of the first connecting frame 504 and the second connecting frame 604 are changed. At this time, the third motor 8 needs to be started and the second gear 801 is controlled to rotate. By the meshing of the second gear 801 and the second side ring tooth 411, the third notched ring plate 403 is rotated. Since the first long gear 505 and the second long gear 605 are respectively meshed with the corresponding second arm ring teeth 410, when the third notched ring plate 403 rotates, the angles of the first connecting frame 504 and the second connecting frame 604 can be changed simultaneously.

[0064] See attached Figures 6 - 10 A connecting rope 530 is connected to the side wall in the middle of the needle rod 508, and a winding wheel 531 for winding up the connecting rope 530 is rotatably installed on one side of the top of the hook frame 507, a clamping wheel shaft 532 is movably inserted at the axis of the center of the winding wheel 531, and a clamping plate 533 for clamping the clamping wheel shaft 532 is provided on the outer wall of the top of the hook frame 507.

[0065] According to the above structure, when the crack detection assembly 5 moves along the surface of the wood 9, the arc hook plate 510 has an arc-shaped bottom surface that fits the surface of the wood 9, and the spherical end of the needle rod 508 fits the surface of the wood 9 at the same time, and the fitting points of the arc hook plate 510, the needle rod 508 and the surface of the wood 9 are at the same point. When encountering a crack on the surface of the wood 9, please refer to Figure 10, the needle rod 508 will move relative to the arc hook plate 510 linearly, and the end of the needle rod 508 will quickly penetrate into the crack under the elastic force of the curved spring I 513 in the compressed state. During this process, relative movement occurs between the curved piercing rod 514 and the first curved pipe 509, and the first electrical contact body 516 will separate from the second electrical contact body 518. When the total control device detects the separation of the first electrical contact body 516 from the second electrical contact body 518, it can be known that there is a crack on the surface of the wood 9 here;

[0066] When the needle rod 508 detects a crack, the movement of the curved piercing rod 514 will simultaneously cause the pry bar 519 to rotate, and the end of the pry bar 519 will drive the push plug column 527 to extend partially from the inside of the injector 525, so that the injector 525 is unblocked. At this time, the ink inside the liquid storage tank 520 will be pushed by the push plug 523 and extruded into the injector 525 by the elastic force of the spring 524, and then sprayed onto the surface of the wood 9 where the crack is located through the ink pipe 528 and the nozzle 529 to achieve the marking work;

[0067] In the above process, the setting of the crack detection assembly 5 can accurately detect the cracks on the surface of the wood 9. The arc hook plate 510 with an arc surface can prevent the protrusion from blocking the movement of the device. The inclined needle rod 508 can also automatically move out of the crack as the assembly moves when it detects a crack. In addition, the settings of the liquid storage tank 520, the injector 525, and the nozzle 529 can automatically mark the crack when it is detected. The marking process does not require any electronic component control, and it has sensitive triggering and a compact structure.

[0068] The working principle of the present invention is: when encountering a crack on the surface of the wood 9, please refer to Figure 10 , the needle rod 508 will move relative to the arc hook plate 510 linearly, and the end of the needle rod 508 will quickly penetrate into the crack under the elastic force of the curved spring I 513 in the compressed state. During this process, relative movement occurs between the curved piercing rod 514 and the first curved pipe 509, and the first electrical contact body 516 will separate from the second electrical contact body 518. When the total control device detects the separation of the first electrical contact body 516 from the second electrical contact body 518, it can be known that there is a crack on the surface of the wood 9 here; when the needle rod 508 detects a crack, the movement of the curved piercing rod 514 will simultaneously cause the pry bar 519 to rotate, and the end of the pry bar 519 will drive the push plug column 527 to extend partially from the inside of the injector 525, so that the injector 525 is unblocked. At this time, the ink inside the liquid storage tank 520 will be pushed by the push plug 523 and extruded into the injector 525 by the elastic force of the spring 524, and then sprayed onto the surface of the wood 9 where the crack is located through the ink pipe 528 and the nozzle 529 to achieve the marking work.

[0069] Embodiment 4:

[0070] Refer to the appendix Figure 11, elastic telescopic rods two 606 are fixedly connected to the bottom ends on both sides of the connecting rod two 604, and a detection frame 607 is fixedly connected to the ends of adjacent two elastic telescopic rods two 606.

[0071] Refer to the appendix Figure 11 , detection touch rods 608 are rotationally connected to the surface of the detection frame 607 in an array manner, and distance-limiting plates 609 for limiting the extreme positions of the corresponding detection touch rods 608 are integrally arranged on the side wall of the detection frame 607 in an array manner. Conductive rods one 610 are fixedly arranged on the side walls of the detection touch rods 608 close to the transfer end. A housing 611 is integrally arranged on one side of the detection frame 607. Curved tubes two 612 are fixedly arranged on the surface of the housing 611 close to the detection touch rods 608 in an array manner. A conductive rod two 613 is elastically telescopically assembled in the interior of the curved tube two 612 through a curved spring two 614 arranged therein. A detection board 615 is fixedly installed inside the housing 611, and the conductive rods one 610 and the curved tubes two 612 are both connected to the detection board 615 through wires.

[0072] According to the above structure, when the scab detection assembly 6 moves along the surface of the wood 9, the bottom ends of the detection touch rods 608 are all in contact with the surface of the wood 9, and the conductive rods one 610 are in contact with the corresponding conductive rods two 613. The curved spring two 614 is used to ensure that the two are in close contact. After the position and angle of the scab detection assembly 6 are successfully set initially, the detection board 615 records the initial current magnitude flowing through the conductive rod two 613 and the conductive rod one 610 at this time. The current is guided to the conductive rod two 613 through the curved tube two 612, then to the conductive rod one 610, and finally back to the detection board 615. The amount of the part of the conductive rod two 613 extending out of the interior of the curved tube two 612, that is, the resistance magnitude encountered by the current when flowing through the conductive rod two 613, directly affects the magnitude of the current returning to the detection board 615. Therefore, when the detection touch rod 608 contacts the raised scab on the surface of the wood 9 during the movement of the scab detection assembly 6, the corresponding conductive rod two 613 will retract into the corresponding curved tube two 612, and a change in the current magnitude will be measured at the current measurement point of the detection touch rod 608 at this position on the detection board 615, and it can be determined that the raised scab is detected by the detection touch rod 608 at this place. In the above process, the setting of the scab detection assembly 6 can accurately and sensitively detect the raised parts on the surface of the wood 9. Since most of the raised parts on the surface of the wood 9 are the positions of diseased scabs, the scabs on the surface of the wood 9 can be detected, endowing the detection device with the function of detecting other defects and further expanding the use range of the device.

[0073] The working principle of the present invention is as follows: when the scab detection component 6 moves along the surface of the wood 9, the bottom ends of the detection touch rods 608 are all in contact with the surface of the wood 9, and each first conductive rod 610 is in contact with the corresponding second conductive rod 613. The curved spring two 614 is used to ensure that the two are closely attached. After the position and angle of the scab detection component 6 are successfully set initially, the detection board 615 records the initial current magnitude flowing through the second conductive rod 613 and the first conductive rod 610 at this time. The current is guided to the second conductive rod 613 through the curved tube two 612, then to the first conductive rod 610, and finally back to the detection board 615. The amount of the part of the second conductive rod 613 extending from the inside of the curved tube two 612 (i.e., the resistance magnitude encountered by the current when flowing through the second conductive rod 613) directly affects the magnitude of the current returning to the detection board 615. Therefore, when the detection touch rod 608 contacts the raised scab on the surface of the wood 9 during the movement of the scab detection component 6, the corresponding second conductive rod 613 will retract into the corresponding curved tube two 612, and a change in the current magnitude will be measured at the current measurement point of the detection touch rod 608 at this position on the detection board 615, and it can be determined that the raised scab is detected by the detection touch rod 608 at this place.

[0076] The working principle of the present invention is as follows: when the notch ring 305 moves around the surface of the wood 9, the setting of the third elastic telescopic rod 10 can ensure that the hard row brush 1001 is closely attached to the surface of the wood 9. When the notch ring 305 moves, the hard row brush 1001 can brush off the sundries attached to the surface of the wood 9 in a spiral path manner, thereby avoiding the influence of surface foreign matters on the detection work and ensuring the authenticity and accuracy of the detection results.

[0078] Step 1: Pass the wood 9 through the top machine plate 301, and use the round wood clamp 2 to fix the end of the wood 9;

[0079] Step 2: First start the second motor 7 and control the rotation of the notch ring plate two 402, and control all the crack detection components 5 and scab detection components 6 to move together towards the wood 9 until the bottom surface of the arc hook plate 510 and the bottom ends of the detection touch rods 608 are in contact with the surface of the wood 9;

[0080] Step 3: Then start the third motor 8 and control the rotation of the notch ring plate three 403 to adjust the angles of all the first connecting frames 504 and the second connecting frames 604;

[0081] Step 4: Drive the detection rack 3 to move linearly through the orbiting machine, and at the same time drive the driving crawler 303 through the first motor 302. Then, the notch ring 305 will carry the distance adjustment ring group 4, the crack detection assembly 5, and the scab detection assembly 6 to simultaneously perform a circular motion around the surface of the wood 9, so as to realize the detection of the surface quality of the wood 9;

[0082] Step 5: Collect the detection results and process the defective parts of the wood 9.
