Description

Technical Field

[0001] The invention relates to the technical field of telescopic booms, and in particular to a telescopic boom for a tire-type stacker and a use method thereof. Background Art

[0002] When a tire stacker is performing stacking operations, its telescopic boom needs to be frequently extended and moved to stack materials in different locations. When a stacker is working in a complex environment, obstacles in the environment will limit the telescopic range of the stacker's boom. If the movement of the boom exceeds the predetermined safety range, it may cause the boom to collide with obstacles.

[0003] Traditional stacker booms are usually set with a fixed safety range, which cannot adapt to the changing working environment. At the same time, when the stacker is working, the boom may exceed the safety range due to operator errors or failure of the drive device. Since the stacker boom lacks an effective alarm mechanism, the operator cannot receive a warning in time, thereby increasing the risk of safety accidents. Therefore, a telescopic boom for a tire stacker and a method of using the same are extremely important.

The above patent realizes changing the height of the laser scanner by telescopic bracket to meet the scanning requirements of coal piles of different heights. However, the above patent cannot realize the alarm function when the stacker arm is about to exceed the safety range.

The above patent realizes the separate and simultaneous operations of material stacking in two material yards, but the above patent cannot realize the detection function of the telescopic range of the stacking machine arm.

[0006] 3. Patent document CN114275547B discloses a pitch fixing tool and a stacker-reclaimer boom. The above patent realizes that there is no need for welding during maintenance, the boom can be quickly fixed, and disassembly and assembly are convenient, which greatly reduces the maintenance time of the stacker-reclaimer pitch cylinder. However, the above patent cannot realize the locking function when the stacker boom is about to exceed the specified range.

[0007] 4. Patent document CN110834966B discloses a stacker-reclaimer cantilever anti-collision detection device and a stacker-reclaimer cantilever having the same. The above patent realizes timely stopping when a collision occurs during the cantilever rotation process to avoid accidents, but the above patent cannot realize the collision buffering function when the stacker boom is extended or retracted.

[0008] In summary, the above patents cannot realize the alarm function when the stacker boom is about to exceed the safety range, cannot realize the detection function of the telescopic range of the stacker boom, cannot realize the locking function when the stacker boom is about to exceed the safety range, and cannot realize the collision buffer function when the stacker boom is telescopic, resulting in the stacker boom telescoping beyond the specified range, causing the boom to collide with obstacles, the stacking position to deviate, and the boom to be damaged;

[0009] To this end, the present application proposes a telescopic arm for a tire-type stacker, which has an alarm function when the stacker arm is about to exceed a safety range, a detection function for the telescopic range of the stacker arm, a locking function when the stacker arm is about to exceed the safety range, and a collision buffer function when the stacker arm is telescoped.

[0052] Example 1, please refer to Figure 1 , Figure 2 and Figure 3 A telescopic boom for a tire-type stacker, comprising a mounting frame 1 and a telescopic warning module, wherein the mounting frame 1 is provided with a telescopic warning module, and the telescopic warning module is used to adjust the telescopic range of the equipment and to send out an alarm when the equipment telescopes beyond a limited range;

[0053] The telescopic warning module includes: an audible and visual alarm 5, a first motor 6, a limit block 11, a first distance sensor 12 and a first pressure sensor 19;

[0054] The outer wall of the installation frame 1 is symmetrically installed with a plurality of sound and light alarms 5, the installation frame 1 is movably sleeved on the outer wall of the telescopic plate 2, the outer wall of the installation frame 1 is symmetrically fixed with a hydraulic rod 3, the side wall of the hydraulic rod 3 is fixedly connected with a connecting block 13, the side wall of the connecting block 13 is fixedly connected with the telescopic plate 2, a movable groove 4 is opened on the inner wall of the installation frame 1, a first motor 6 is fixedly installed in the installation frame 1, a first rotating shaft 7 is movably installed on the side wall of the first motor 6, the first rotating shaft 7 is movably installed in the movable groove 4, the outer wall of the first rotating shaft 7 is movably sleeved with a first movable block 9, the outer wall of the first movable block 9 is movably sleeved with a movable groove 4, and the side wall of the first movable block 9 The wall is fixedly connected with a second moving block 10, and a first distance sensor 12 is fixedly installed on the side wall of the second moving block 10, and the first distance sensor 12 is connected to a first motor 6 via Bluetooth. The side wall of the second moving block 10 is fixedly connected to a limiting block 11, and a limiting groove 8 is provided on the side wall of the telescopic plate 2, and the limiting groove 8 is movably sleeved on the outer wall of the limiting block 11, and the outer wall of the limiting block 11 is symmetrically fixedly connected with a first pressure sensor 19, and the first pressure sensor 19 is connected to an audible and visual alarm 5 via Bluetooth, and the outer wall of the first pressure sensor 19 is symmetrically fixedly connected with a buffer pad 20, and the first pressure sensor 19 is connected to a hydraulic rod 3 via Bluetooth;

[0055] The first motor 6 is connected to a limit position analysis module via Bluetooth. The limit position analysis module is installed on the installation frame 1. The limit position analysis module is used to analyze the safe range of the equipment extension and retraction. The limit position analysis module includes: an intelligent analyzer 14, a core controller 15 and a high-definition camera 18;

[0056] An intelligent analyzer 14 is fixedly installed on the side wall of the installation frame 1, and the intelligent analyzer 14 is connected to a core controller 15 via Bluetooth. The side wall of the core controller 15 is fixedly connected to the installation frame 1, and the core controller 15 is connected to a first motor 6, a first pressure sensor 19 and a first distance sensor 12 via Bluetooth. A second motor 16 is fixedly installed on the top of the outer wall of the installation frame 1, and the second motor 16 is connected to the core controller 15 via Bluetooth. A second rotating shaft 17 is movably installed on the top of the outer wall of the second motor 16, and a rotating block 60 is fixedly mounted on the outer wall of the second rotating shaft 17. A high-definition camera 18 is fixedly installed on the outer wall of the rotating block 60 at equal intervals, and the intelligent analyzer 14 is connected to the high-definition camera 18 via Bluetooth;

[0057] Further, the operator uploads the stacking position of the stacker to the intelligent analyzer 14. The intelligent analyzer 14 uses the real-time image captured by the high-definition camera 18 to judge and analyze the distance between the installation frame 1 and the obstacle. When the intelligent analyzer 14 detects that the image of a certain high-definition camera 18 is unclear or incomplete, the intelligent analyzer 14 judges that there is a problem with the high-definition camera 18. The intelligent analyzer 14 controls the second motor 16 to start through the core controller 15. The second motor 16 drives the second rotating shaft 17 to rotate. The second rotating shaft 17 drives the rotating block 60 to rotate. The rotating block 60 drives the high-definition camera 18 to rotate, thereby moving the high-definition camera 18 without fault to the original position of the high-definition camera 18 with fault, so that the intelligent analyzer 14 can analyze the complete image data around the installation frame 1, thereby obtaining accurate results.

[0058] The intelligent analyzer 14 determines the safe range of movement of the telescopic plate 2 according to the image data of the obstacle, and the intelligent analyzer 14 generates a distance threshold. The core controller 15 receives the distance threshold set by the intelligent analyzer 14 and transmits the distance threshold to the first distance sensor 12. After the core controller 15 transmits the threshold, it starts the first motor 6, and the first motor 6 drives the first rotating shaft 7 to rotate, and the first rotating shaft 7 drives the first moving block 9 to move in the moving groove 4, and the first moving block 9 drives the second moving block 10 to move, and the second moving block 10 drives the limit block 11 to move in the limit groove 8, and the second moving block 10 drives the first distance sensor 12 to move. When the first distance sensor 12 detects that the distance between itself and the installation frame 1 reaches the threshold, the first distance sensor 12 turns off the first motor 6, thereby adjusting the position of the limit block 11 in the installation frame 1, and then adjusting the contact position of the limit block 11 and the telescopic plate 2.

[0059] After the first distance sensor 12 transmits the signal of adjustment completion to the intelligent analyzer 14, the intelligent analyzer 14 starts the hydraulic rod 3 through the core controller 15, and the hydraulic rod 3 drives the connecting block 13 and the telescopic plate 2 to move. When the extension distance of the telescopic plate 2 is about to exceed the safe range, one side of the limit groove 8 in the telescopic plate 2 contacts the buffer pad 20 around the limit block 11, so that the telescopic plate 2 squeezes the buffer pad 20, and the buffer pad 20 squeezes the first pressure sensor 19. After the first pressure sensor 19 detects the pressure, the hydraulic rod 3 is closed to prevent the telescopic plate 2 from continuing to extend. When the hydraulic rod 3 does not stop or the operator makes a mistake in manually adjusting the telescopic boom of the stacker so that the hydraulic rod 3 extends, the first pressure sensor 1 9 detects that the pressure continues to increase. When the first pressure sensor 19 detects that the pressure reaches the threshold value, the first pressure sensor 19 will activate the sound and light alarm 5 to remind the operator to pay attention. By adjusting the contact position of the limit block 11 and the telescopic plate 2, the telescopic range of the telescopic plate 2 is limited, so that the extension distance of the telescopic plate 2 is kept within a safe range, and the telescopic plate 2 is prevented from further extension and collision with obstacles. Through the sound and light warning of the sound and light alarm 5, when the telescopic plate 2 reaches the boundary of the safe extension distance, it is avoided that the hydraulic rod 3 fails and cannot be discovered in time, and the operator's erroneous operation causes the telescopic plate 2 to continue to extend, causing the telescopic plate 2 to collide with obstacles, thereby damaging the telescopic boom.

[0062] A second hollow groove 30 is provided in the limit block 11, and a rotating shaft 31 is symmetrically and movably installed in the second hollow groove 30, and a first gear 32 is fixedly connected to the outer wall of the rotating shaft 31, and a motor bracket 34 is fixedly installed on the outer wall of the second hollow groove 30, and a third motor 36 is fixedly installed on the side wall of the motor bracket 34, and the third motor 36 is connected to the first pressure sensor 19 via Bluetooth, and a third rotating shaft 35 is movably installed on the side wall of the third motor 36, and a second gear 33 is fixedly connected to the outer wall of the third rotating shaft 35, and the first gear 32 is meshed with the second gear 33, and a third movable block 37 is symmetrically and movably sleeved on the outer wall of the rotating shaft 31, and the third movable block 37 is installed on both sides of the first gear 32, and the threads of the rotating shaft 31 on both sides of the second gear 33 are opposite, and the threads of the rotating shaft 31 match the threads of the third movable block 37, and a second spring 38 is fixedly connected to the side wall of the third movable block 37, and the side wall of the second spring 38 is fixedly connected to one side of the brake pad 39, and the other side of the brake pad 39 faces the telescopic plate 2;

[0063] Further, the telescopic plate 2 moves. When the extension distance of the telescopic plate 2 is about to exceed the safe range, the telescopic plate 2 contacts the buffer pad 20 around the limit block 11, so that the telescopic plate 2 squeezes the buffer pad 20, and the buffer pad 20 squeezes the first pressure sensor 19. When the first pressure sensor 19 detects that the pressure data reaches the threshold, the first pressure sensor 19 starts the sound and light alarm 5.

The third motor 36 drives the third shaft 35 to rotate, the third shaft 35 drives the second gear 33 to rotate, the second gear 33 drives the first gear 32 to rotate, the first gear 32 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the third moving block 37 to move, so that the third shaft 35 on both sides of the first gear 32 is rotated. The moving block 37 gradually moves away, and the third moving block 37 drives the second spring 38 to move, and the second spring 38 drives the brake pad 39 to move, so that the brake pad 39 gradually approaches the telescopic plate 2. The second spring 38 prevents the brake pad 39 from being too tight with the telescopic plate 2, which causes the telescopic plate 2 to be deformed, or too loose, which causes the limit block 11 to fix the telescopic plate 2 poorly. Under the action of the brake pad 39, the limit block 11 fixes the telescopic plate 2 to prevent the telescopic plate 2 from moving further, thereby preventing the telescopic plate 2 from driving the limit block 11, the second moving block 10 and the first moving block 9 to move, preventing the first moving block 9 from moving on the first rotating shaft 7, and preventing damage to the threads of the first rotating shaft 7 and the first moving block 9, thereby solving the problem that the telescopic arm frame is damaged due to the further movement of the telescopic plate 2 and colliding with an obstacle.

[0064] Example 3, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 8A telescopic boom for a tire-type stacker, comprising a mounting frame 1 and a telescopic warning module, wherein the mounting frame 1 is provided with a telescopic warning module, wherein the telescopic warning module is used to adjust the telescopic range of the equipment and to send out an alarm when the equipment telescopes beyond a limited range; the telescopic warning module comprises: an audible and visual alarm 5, a first motor 6, a limit block 11, a first distance sensor 12 and a first pressure sensor 19;

[0065] The first motor 6 is connected to a limit position analysis module via Bluetooth. The limit position analysis module is installed on the installation frame 1. The limit position analysis module is used to analyze the safe range of equipment extension and retraction. The limit position analysis module includes: an intelligent analyzer 14, a core controller 15 and a high-definition camera 18;

[0066] The limit block 11 is provided with a limit protection module, which is used to prevent the telescopic plate 2 from moving out of the safe telescopic range of the device; the limit protection module uses a braking mechanism and a locking mechanism; the locking mechanism in the limit protection module includes: a first spring 22, a locking block 23, a roller 25, a push rod 26 and an electric push rod 27;

[0067] A first hollow groove 21 is symmetrically provided in the limit block 11, a locking block 23 is movably installed in the first hollow groove 21, a first spring 22 is fixedly connected to the side wall of the locking block 23, and a side wall of the first spring 22 is fixedly connected to the limit block 11, a plurality of locking grooves 29 are provided on the telescopic plate 2, the locking groove 29 is communicated with the limit groove 8, the size of the locking groove 29 is slightly larger than the outer diameter of the locking block 23, an oblique groove 24 is provided on the side wall of the locking block 23, a mounting groove 28 is symmetrically provided in the locking block 23, the mounting groove 28 is communicated with the first hollow groove 21, an electric push rod 27 is fixedly installed in the mounting groove 28, a locking block 23 is fixedly connected to one side of the electric push rod 27, a push rod 26 is fixedly connected to the other side of the electric push rod 27, a roller 25 is connected to the push rod rotating shaft of the push rod 26, the roller 25 is in contact with the oblique groove 24, and the electric push rod 27 is connected to the first pressure sensor 19 and the core controller 15 via Bluetooth;

[0068] Further, the telescopic plate 2 moves. When the extension distance of the telescopic plate 2 is about to exceed the safety range, the telescopic plate 2 contacts the buffer pad 20, so that the telescopic plate 2 squeezes the buffer pad 20, and the buffer pad 20 squeezes the first pressure sensor 19. When the first pressure sensor 19 detects that the pressure data reaches the threshold, the first pressure sensor 19 activates the sound and light alarm 5. At the same time, the first pressure sensor 19 activates the electric push rod 27, and the electric push rod 27 drives the push rod 26 to move right, so that the push rod 26 is completely moved into the installation groove 28. The roller 25 on the push rod 26 no longer contacts the inclined groove 24 on the locking block 23, and the first spring 22 recovers from the compressed state to the original state. The first spring 22 elastically pushes the locking block 23, so that the locking block 23 in the first hollow groove 21 pops out, so that the locking block 23 enters the locking groove 29 on the telescopic plate 2, and under the action of the locking block 23, the limit block 11 fixes the telescopic plate 2 to prevent the telescopic plate 2 from moving further.

[0069] After receiving the alarm signal from the sound and light alarm 5, the operator checks the telescopic arm of the stacker, and retracts the telescopic plate 2 of the stacker through the intelligent analyzer 14. The intelligent analyzer 14 starts the electric push rod 27 through the core controller 15. The core controller 15 controls the electric push rod 27 to drive the push rod 26 to move to the left, so that the roller 25 on the push rod 26 contacts the inclined groove 24 on the locking block 23. Under the action of the electric push rod 27 and the push rod 26, the roller 25 rolls on the surface of the inclined groove 24 on the locking block 23, so that the roller 25 drives the locking block 23 to move, and the locking block 23 compresses the first spring 22, so that the locking block 23 returns to its original position, so that the limit block 11 no longer fixes the telescopic plate 2, so that the telescopic plate 2 can be smoothly retracted. Compared with the braking mechanism, the locking mechanism fixes the limit block 11 by locking the locking block 23 into the locking groove 29, and the wear of the locking block 23 and the locking groove 29 is small. The braking mechanism will cause aggravated wear when used multiple times, reducing the service life.

[0070] Example 4, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 A telescopic boom for a tire-type stacker, comprising a mounting frame 1 and a telescopic warning module, wherein the mounting frame 1 is provided with a telescopic warning module, wherein the telescopic warning module is used to adjust the telescopic range of the equipment and to send out an alarm when the equipment telescopes beyond a limited range; the telescopic warning module comprises: an audible and visual alarm 5, a first motor 6, a limit block 11, a first distance sensor 12 and a first pressure sensor 19; a plurality of audible and visual alarms 5 are symmetrically mounted on the outer wall of the mounting frame 1, the mounting frame 1 is movably mounted on the outer wall of the telescopic plate 2, a hydraulic rod 3 is symmetrically fixedly mounted on the outer wall of the mounting frame 1, a connecting block 13 is fixedly connected to the side wall of the hydraulic rod 3, and a telescopic plate 2 is fixedly connected to the side wall of the connecting block 13;

[0071] The first motor 6 is connected to a limit position analysis module via Bluetooth. The limit position analysis module is installed on the installation frame 1. The limit position analysis module is used to analyze the safe range of equipment extension and retraction. The limit position analysis module includes: an intelligent analyzer 14, a core controller 15 and a high-definition camera 18;

[0072] The connection block 13 is provided with a collision buffer module, which is used for buffering when the device moves and extends and collides with the device; the collision buffer module includes: a moving shaft 41, a rubber block 42, a second pressure sensor 43, a buffer spring 44 and a buffer block 45;

[0073] The side wall of the connecting block 13 is fixedly connected with a connecting shaft 40, a moving shaft 41 is installed in the connecting shaft 40, the connecting block 13 is movably mounted on the outer wall of the moving shaft 41, a buffer spring 44 is movably mounted on the outer wall of the moving shaft 41, a buffer block 45 and the connecting block 13 are fixedly connected to the outer wall of the buffer spring 44, a buffer block 45 is fixedly connected to one side of the moving shaft 41, a rubber block 42 is fixedly connected to the other side of the moving shaft 41, a buffer groove 67 is opened in the connecting block 13, the rubber block 42 is installed in the buffer groove 67, a second pressure sensor 43 is fixedly installed on the side wall of the buffer groove 67, and the second pressure sensor 43 is connected to the hydraulic rod 3 via Bluetooth;

[0074] Further, under the action of the intelligent analyzer 14, the core controller 15 and the high-definition camera 18, the threshold value of the safe range of movement of the telescopic plate 2 is transmitted to the first distance sensor 12, and under the action of the first motor 6 and the first distance sensor 12, the limit block 11 moves to the specified position to limit the movement range of the telescopic plate 2, and the hydraulic rod 3 is started, and the hydraulic rod 3 drives the connecting block 13 to move, and the connecting block 13 drives the telescopic plate 2 to move, and the telescopic plate 2 moves to the specified position. When an obstacle around the installation frame 1 suddenly appears within the safe range of movement of the telescopic plate 2, the intelligent analyzer 14 fails to re-determine the new safe range of the telescopic plate 2, so that the telescopic plate 2 fails to stop moving in time, causing the telescopic plate 2 to collide with the obstacle. At this time, the buffer block 45 at the front end of the telescopic plate 2 will first contact the obstacle, causing the buffer block 4 5 drives the moving shaft 41 to move in the connecting shaft 40, so that the buffer block 45 compresses the buffer spring 44 to prevent the obstacle from directly contacting the telescopic plate 2, thereby reducing the impact on the stacker boom. The telescopic plate 2 continues to extend, and the obstacle squeezes the buffer block 45, so that the buffer block 45 drives the moving shaft 41, and the moving shaft 41 drives the rubber block 42 to move in the buffer groove 67. When the rubber block 42 contacts the second pressure sensor 43, the second pressure sensor 43 detects the pressure, and the second pressure sensor 43 immediately closes the hydraulic rod 3 to stop the telescopic plate 2 from continuing to extend. When the buffer spring 44 reaches the compression limit, the telescopic plate 2 is stopped from continuing to move in time to prevent the telescopic plate 2 from being damaged. Under the protection and buffering effect of the buffer block 45 and the buffer spring 44, the impact of the stacker boom colliding with the sudden obstacle is reduced.

[0075] Example 5, please refer to Figure 1 , Figure 2 and Figure 7 A telescopic boom for a tire-type stacker, comprising a mounting frame 1 and a telescopic warning module, wherein the mounting frame 1 is provided with a telescopic warning module, wherein the telescopic warning module is used to adjust the telescopic range of the equipment and to send out an alarm when the equipment telescopes beyond a limited range; the telescopic warning module comprises: an audible and visual alarm 5, a first motor 6, a limit block 11, a first distance sensor 12 and a first pressure sensor 19; a plurality of audible and visual alarms 5 are symmetrically mounted on the outer wall of the mounting frame 1, the mounting frame 1 is movably mounted on the outer wall of the telescopic plate 2, a hydraulic rod 3 is symmetrically fixedly mounted on the outer wall of the mounting frame 1, a connecting block 13 is fixedly connected to the side wall of the hydraulic rod 3, and a telescopic plate 2 is fixedly connected to the side wall of the connecting block 13;

[0078] Further, under the action of the hydraulic rod 3, the core controller 15 and the first pressure sensor 19, the hydraulic rod 3 drives the connecting block 13 and the telescopic plate 2 to move, so that the telescopic plate 2 moves to the specified position, and the operator uploads the data of the type of materials to be stacked to the intelligent analyzer 14. The intelligent analyzer 14 determines the carrying range of the first conveyor belt 58 in the installation frame 1 and the second conveyor belt 59 on the telescopic plate 2 according to the material type and the parameter data of the telescopic arm itself, and judges the optimal quantity of each transportation of the first conveyor belt 58 and the second conveyor belt 59, thereby analyzing the optimal height of the materials stacked on the first conveyor belt 58 and the second conveyor belt 59. The intelligent analyzer 14 sets a corresponding distance threshold to avoid excessive accumulation of materials on the first conveyor belt 58 and the second conveyor belt 59, resulting in the inability to support the installation frame 1, the connecting plate 68 and the telescopic plate 2, thereby causing damage to the stacker arm, and to avoid too little material being transported on the first conveyor belt 58 and the second conveyor belt 59, affecting efficiency;

[0079] The fourth motor 46 is started, the fourth motor 46 drives the fourth rotating shaft 47 to rotate, the fourth rotating shaft 47 drives the lifting block 48 to move, the lifting block 48 drives the lifting plate 49 to move on the moving rod 50, the lifting plates 49 and the moving rod 50 on both sides of the lifting block 48 prevent the lifting block 48 from being unevenly stressed, resulting in misalignment of the lifting block 48 when moving, the lifting block 48 drives the mounting plate 52, the fifth motor 54, the fifth rotating shaft 55, the mounting block 53, and the material-digging plate 56 to move, the material-digging plate 56 drives the second distance sensor 57 to move, the second distance sensor 57 transmits the distance data to the intelligent analyzer 14 in real time, and when the intelligent analyzer 14 detects that the distance data reaches the threshold value, the intelligent analyzer 14 The instrument 14 turns off the fourth motor 46 through the core controller 15 to stop running, moves the material plate 56 to a suitable height, starts the fifth motor 54, drives the fifth rotating shaft 55 to rotate, and the fifth rotating shaft 55 drives the mounting block 53 and the material plate 56 to rotate. The material plate 56 rotates to above the first conveyor belt 58, and the operator pours the material onto the first conveyor belt 58. The material is gradually transferred to the installation frame 1 under the action of the first conveyor belt 58. The material plate 56 disperses the material so that the material is dispersed on the first conveyor belt 58. The first conveyor belt 58 transfers the material to the second conveyor belt 59, and the second conveyor belt 59 transfers the material to the designated position for stacking.

[0080] Example 6, please refer to Figure 1 , Figure 2 and Figure 6 A telescopic boom for a tire-type stacker, comprising a mounting frame 1 and a telescopic warning module, wherein the mounting frame 1 is provided with a telescopic warning module, wherein the telescopic warning module is used to adjust the telescopic range of the equipment and to send out an alarm when the equipment telescopes beyond a limited range; the telescopic warning module comprises: an audible and visual alarm 5, a first motor 6, a limit block 11, a first distance sensor 12 and a first pressure sensor 19; a plurality of audible and visual alarms 5 are symmetrically mounted on the outer wall of the mounting frame 1, the mounting frame 1 is movably mounted on the outer wall of the telescopic plate 2, a hydraulic rod 3 is symmetrically fixedly mounted on the outer wall of the mounting frame 1, a connecting block 13 is fixedly connected to the side wall of the hydraulic rod 3, and a telescopic plate 2 is fixedly connected to the side wall of the connecting block 13;

[0081] The connecting block 13 is provided with a collision buffer module, which is used for buffering when the device moves and telescopes and collides with the device; the collision buffer module comprises: a moving shaft 41, a rubber block 42, a second pressure sensor 43, a buffer spring 44 and a buffer block 45; the connecting block 13 is fixedly connected to the side wall with the connecting shaft 40, the moving shaft 41 is installed in the connecting shaft 40, the connecting block 13 is movably sleeved on the outer wall of the moving shaft 41, the outer wall of the moving shaft 41 is movably sleeved with a buffer spring 44, the outer wall of the buffer spring 44 is fixedly connected with a buffer block 45 and the connecting block 13, one side of the moving shaft 41 is fixedly connected with the buffer block 45, the other side of the moving shaft 41 is fixedly connected with the rubber block 42, a buffer groove 67 is provided in the connecting block 13, the rubber block 42 is installed in the buffer groove 67, the side wall of the buffer groove 67 is fixedly installed with a second pressure sensor 43, and the second pressure sensor 43 is connected to the intelligent analyzer 14 via Bluetooth;

[0082] The outer wall of the connecting shaft 40 is fixedly sleeved with a fixing block 61, the side wall of the fixing block 61 is fixedly connected with a placing plate 62, the outer top of the placing plate 62 is fixedly connected with a sixth motor 63, the outer top of the sixth motor 63 is movably mounted with a sixth rotating shaft 64, the outer top of the sixth rotating shaft 64 is fixedly connected with an arc wheel 65, the outer bottom of the buffer block 45 is fixedly connected with a rubber plate 66, and the rubber plate 66 is in contact with the arc wheel 65;

[0083] Further, the telescopic plate 2 moves to the specified position, and the material is transferred from the first conveyor belt 58 to the second conveyor belt 59. The second conveyor belt 59 transfers the material to the specified position for stacking. When too much material is transferred, the material will accumulate between the second conveyor belt 59 and the buffer block 45, thereby affecting the transmission of the material. At this time, the operator starts the sixth motor 63, and the sixth motor 63 drives the sixth rotating shaft 64. The sixth rotating shaft 64 drives the arc wheel 65, so that the longer end and the shorter end of the arc wheel 65 alternately face the rubber plate 66. When the longer end of the arc wheel 65 faces the rubber plate 66, the arc wheel 65 drives the rubber plate 66 and the buffer block 45, and the buffer block 45 stretches the buffer spring 44. When the shorter end of the arc wheel 65 faces the rubber plate 66, the buffer spring 44 drives the buffer block 45 to restore the original position, so that the buffer block 45 vibrates continuously, and then shakes off the material to avoid excessive accumulation of material that may cause the telescopic plate 2 and the second conveyor belt 59 to be unable to support, thereby preventing damage to the arm.

[0084] Working principle: the intelligent analyzer 14 determines the safe range of movement of the telescopic plate 2 through the real-time image captured by the high-definition camera 18, the core controller 15 sets the distance threshold of the intelligent analyzer 14 and transmits the distance threshold to the first distance sensor 12, the core controller 15 starts the first motor 6, and when the limit block 11 moves to the specified position, the first distance sensor 12 turns off the first motor 6;

[0085] The hydraulic rod 3 drives the connecting block 13 and the telescopic plate 2 to move. The first pressure sensor 19 detects the pressure and then shuts down the hydraulic rod 3. The operator mistakenly starts the hydraulic rod 3 or the hydraulic rod 3 fails and continues to drive the telescopic plate 2 to move. The pressure detected by the first pressure sensor 19 gradually reaches the threshold. The first pressure sensor 19 will start the sound and light alarm 5 to remind the operator to pay attention. At the same time, the first pressure sensor 19 starts the third motor 36 or the electric push rod 27 to lock the limit block 11.

[0086] When the telescopic plate 2 moves within the safe range, an obstacle suddenly appears within the safe range. The obstacle collides with the buffer block 45 at the front end of the telescopic plate 2. The buffer block 45 and the buffer spring 44 provide protection and vibration reduction. The second pressure sensor 43 detects the pressure. The second pressure sensor 43 immediately closes the hydraulic rod 3 and stops the telescopic plate 2 from moving further.

[0087] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
