Description

Technical Field

[0001] The invention belongs to the technical field of material grabbers, in particular to a material grabber with a dual-power hydraulic drive system. Background Art

[0002] At present, due to the limited space of wood processing enterprises, the extra raw materials collected during the peak season of wood felling need to be stacked and palletized. The general wood grabber grab is connected by a wire rope and hung under the main arm for stacking. There is also a wood grabber that uses an excavator to load and unload materials. The wood grabber uses a diesel engine as power to drive a hydraulic pump to achieve various actions. The above two methods are both commonly used technologies for realizing the transportation and stacking of wood.

[0003] Chinese invention patent application CN116553205A discloses a grabber comprising: a main machine; a hopper having two or more lobes capable of digging and grabbing materials by changing from an open state to a closed state; a hopper drive and holding mechanism, one end of which is connected to the top of the hopper; the grabber has great difficulty in grabbing materials and low grabbing accuracy.

[0004] Chinese invention patent CN108622653B provides a grasping and feeding robot, including a moving unit, a base plate, a rotating lifting unit, a support plate, a slider A, a slide rail A, a rack rod plate, a first motor mounting seat, a grasping unit, a first motor, a gear, a second motor, and a flange adapter plate, characterized in that: the two moving units are respectively installed on both sides of the base plate; the grasping efficiency of the grasping machine is low and the grasping effect is poor.

[0005] Most of the above-mentioned grabbers are single-power hydraulic drive systems. When the hydraulic drive system is damaged, it takes a long time to repair it, thereby reducing the subsequent normal grabbing efficiency.

[0006] When the grabber grabs the wood, a large amount of impurities often adhere to the outer surface of the wood. If the impurities are not cleaned in time, it will not only pollute the inner wall of the grab bucket, but also reduce the quality of the wood accordingly.

[0007] After the wood is grabbed, the wood is unevenly distributed inside the grab bucket. When the wood is subsequently transported and recycled, the wood is prone to shaking and colliding inside the grab bucket, reducing the safety and stability of the wood and the grab bucket.

[0008] At the same time, when the wood rotates with the grab bucket, the wood will collide with the inner wall of the grab bucket under the action of centrifugal force, thereby causing damage to the grab bucket.

[0009] And when the grab bucket transfers the wood to the top of the vehicle for recycling, if the two grab buckets are opened to both sides, the wood inside the grab bucket will fall directly onto the top of the vehicle, which will not only affect the stability and safety of the vehicle, but also cause the risk of impact and cracking of the wood.

When the sealing slider 418 moves up and down inside the connecting hole 416, the sealing slider 418 synchronously drives the follower plate 421 to move up and down, and the follower plate 421 drives the matching hole 422 to move up and down, and the overlapping area between the matching hole 422 and the docking hole 423 changes, thereby correspondingly adjusting the amount of gas discharged from the docking hole 423, and the thrust applied by the docking hole 423 to the moving scraper 425 changes and drives the moving scraper 425 to move back and forth inside the grabbing bucket 401, thereby ensuring the scraping and cleaning effect of the moving scraper 425 on the inner wall of the grabbing bucket 401.

[0042] The side wall of the support plate 414 is evenly provided with a plurality of connecting springs 424, and the other end of the connecting spring 424 is fixedly connected to the side wall of the mobile scraper 425. The setting of the connecting spring 424 further improves the elastic reset effect of the mobile scraper 425. The bottom of the mobile scraper 425 is evenly provided with a plurality of cleaning holes 426. The setting of the cleaning holes 426 facilitates the circulation of impurities inside the grab bucket 401, further improving the scraping and cleaning quality of the mobile scraper 425 on the inner wall of the grab bucket 401. Due to the different sizes of wind forces discharged from the docking hole 423, the moving scraper 425 stretches the connecting spring 424 and moves different distances inside the grab bucket 401. Therefore, the moving scraper 425 will be tilted and offset accordingly, which not only improves the scraping effect of the moving scraper 425 on different positions of the inner wall of the grab bucket 401, but also drives the cleaning hole 426 to change its position and adjusts the flow position of impurities attached to the inner wall of the grab bucket 401, ensuring that the impurities can be discharged continuously and stably along the multiple discharge holes 411.

[0043] Most of the existing grabbers are single-power hydraulic drive systems. When the hydraulic drive system is damaged, it takes a long time to repair, which reduces the subsequent normal grabbing efficiency. After the grabber grabs the wood, a large amount of impurities often adhere to the outer surface of the wood. If the impurities are not cleaned in time, it will not only pollute the inner wall of the grab bucket 401, but also reduce the quality of the wood accordingly. After the wood is grabbed, the position of the wood is unevenly distributed inside the grab bucket 401, and when the wood is subsequently transported and recycled, the wood is easy to be stuck in the grab bucket 401. The wood will shake and collide with the inside of the grab bucket 401, reducing the safety and stability of the wood and the grab bucket 401; at the same time, when the grab bucket 401 rotates, the wood will collide with the inner wall of the grab bucket 401 under the action of centrifugal force, thereby causing damage to the grab bucket 401; and when the grab bucket 401 transfers the wood to the top of the vehicle for recycling, if the two grab buckets 401 are opened to both sides, the wood inside the grab bucket 401 will fall directly onto the top of the vehicle, which will not only affect the stability and safety of the vehicle, but also cause the risk of impact cracking of the wood.

[0044] In order to solve the above problems, when the grabber with dual-power hydraulic drive system is actually used, the control room 105 first controls the drive unit 103 to start and drives the sprocket 102 to rotate through the transmission unit 104. The sprocket 102 drives the upper rotating platform 109 and the frame 101 to move to the appropriate position. The drive unit 103 stops working, and the telescopic support unit starts and stably supports the ground, thereby improving the subsequent grabbing and rotating effect of the grabbing bucket 401 on the wood.

[0045] Afterwards, the control room 105 controls the diesel engine 201 to start and drives the first main pump 204 to start through the elastic coupling 203. The first main pump 204 applies suction force to the oil tank 209 and allows the hydraulic oil inside the oil tank 209 to enter the main valve 208 along the first one-way valve 206. The hydraulic oil reaches the main hydraulic rod 303, the negative hydraulic rod 305 or the hydraulic clamping rod 429 along the main valve 208, and adjusts the position height of the grab bucket 401 accordingly, thereby improving the grabbing quality and grabbing efficiency.

[0046] If the diesel engine 201 is damaged, the control room 105 controls the motor 202 to start and drives the second main pump 205 to start through the elastic coupling 203. The second main pump 205 applies suction force to the oil tank 209 and the hydraulic oil enters the main valve 208 along the second one-way valve 207. The hydraulic oil continues to reach the main hydraulic rod 303, the negative hydraulic rod 305 or the hydraulic clamping rod 429 along the main valve 208, thereby correspondingly improving the output stability and efficiency of the hydraulic oil. The diesel engine 201 and the motor 202 are replaced and used, which further ensures that the grabber can work without stopping and avoids problems such as low grabbing efficiency due to maintenance.

[0047] The main hydraulic rod 303 starts and drives the bending arm 302 to move around the positioning seat 301. The other end of the bending arm 302 drives the gooseneck arms 304 to move synchronously. At the same time, the negative hydraulic rod 305 drives the gooseneck arms 304 to move. The gooseneck arms 304 synchronously drive the connecting seat 428 to move. The connecting seat 428 drives the fixed frame 403 below to move. The fixed frame 403 drives the two grab buckets 401 to move through the rotating rods 402 on both sides, thereby realizing the subsequent adjustment of the position height of the grab bucket 401.

[0048] When the grabbing bucket 401 moves above the wood, the control room 105 controls the hydraulic clamping rod 429 to start and extend the output end, the output end of the hydraulic clamping rod 429 drives the limit rod 413 to rotate around the rotating rod 402, and the limit rod 413 synchronously drives the two grabbing buckets 401 to move around the rotating rod 402 to move closer to each other, and the two grabbing buckets 401 grab the wood on the ground. During the grabbing process, the control room 105 controls multiple electric push rods 417 to start and shorten the output end to the initial value, and the electric push rods 417 drive the sealing slider 418 moves downward along the connecting hole 416 to the initial value, and the top of the sealing slider 418 is at the same horizontal plane as the top of the support plate 414. Therefore, under the grabbing action of the grabbing bucket 401 on the wood, the wood is continuously accumulated on the support plate 414 under the action of the inclined supporting surface 431 at the top of the support plate 414, and the side wall of the wood inside the grabbing bucket 401 is limited by the limit rod 413, and the wood on the top of the grabbing bucket 401 is supported and limited by the elastic support block 430, which further improves the stability and support of the wood inside the grabbing bucket 401.

[0049] After the two grab buckets 401 are closed, the control room 105 controls multiple electric push rods 417 to start and extend the output ends. The top output end of the electric push rod 417 drives the sealing slider 418 to move along the connecting hole 416 toward the end away from the vent hole 415. The arc-shaped support grooves 419 on both sides of the top of the sealing slider 418 are inserted between two adjacent woods and elastically contact with the side walls of the wood. The pressure sensor 420 detects the pressure value. The bottom wood is elastically supported by the arc-shaped support grooves 419 on the side walls of multiple sealing sliders 418, and cooperates with the limiting rods 413 and the elastic blocks 430 on the surrounding sides to achieve all-round elastic clamping and wrapping of the wood in the remaining positions, so as to prevent the subsequent wood from shaking during transportation and unloading and colliding with the inner wall of the grab bucket 401 to cause damage.

[0050] Since impurities are easily attached to the outer surface of the wood, the control room 105 controls the electric push rod 417 to start and the output end to continuously extend and shorten. The electric push rod 417 synchronously drives the sealing slider 418 to continuously move up and down along the connecting hole 416. The arc-shaped support grooves 419 on both sides of the sealing slider 418 continuously exert force on both sides of the bottom wood and drive the wood to vibrate up and down inside the grab bucket 401. With the help of this vibration force, not only the vibration and compaction effect of the wood is improved, and the wood is closely distributed inside the grab bucket 401, the density and space utilization of the subsequent wood unloading and loading are improved, but also the impurities on the outer surface can be detached and cleaned during the up and down vibration of the wood and the collision with the support plate 414, so as to avoid the impurities reducing the grabbing and recycling quality of the wood.

[0051] The impurities dropped from the outer surface of the wood by the vibration cleaning fall into the grab bucket 401, and at the same time, the control room 105 controls the air blower 427 to start and pass gas into the vent 415, and the sealing slider 418 moves up and down along the connecting hole 416, synchronously driving the follower plates 421 on both sides to move up and down, and the follower plates 421 drive the internal matching holes 422 to move up and down, and because the misaligned distribution area of ​​the matching holes 422 and the docking holes 423 is constantly changing, the amount of air discharged from the vent 415 along the overlapping position of the matching holes 422 and the docking holes 423 to both sides is constantly changing, and the changing amount of gas directly acts on the side wall of the moving scraper 425, thereby driving the moving scraper 425 to stretch the connecting spring 424 to move away The moving distance from the end of the support plate 414 changes, and the moving scraper 425 scrapes the inner wall of the grab bucket 401 laterally during the reciprocating movement. The setting of the cleaning hole 426 realizes the dislocation scraping effect of the moving scraper 425 on the inner wall of the grab bucket 401, avoiding that the impurities attached to the inner wall of the grab bucket 401 are too large and affect the stability and efficiency of the reciprocating movement of the moving scraper 425. At the same time, the moving scraper 425 cooperates with the changing gas volume discharged from the docking hole 423 to achieve the wind scraping effect on the impurities attached to the inner wall of the grab bucket 401, so that the impurities can be completely and effectively discharged along the discharge hole 411, avoiding affecting the subsequent grabbing of wood, effectively improving the cleaning scraping effect, and ensuring the cleanliness of the inner wall of the grab bucket 401 and the unblocking of impurities.

[0052] After completing the vibration cleaning of the wood inside the grab bucket 401, the control room 105 controls the electric push rod 417 to start and the output end drives the sealing slider 418 to move outward along the connecting hole 416 to a suitable position. The arc-shaped support grooves 419 on both sides of the sealing slider 418 are elastically supported by the side walls of the wood. The pressure sensor 420 detects the pressure value of the wood above. When the weight of the wood is unevenly distributed above the support plates 414 on both sides, the center of gravity of the wood is not located between the two support plates 414. At this time, problems such as shaking and warping of the wood will occur when the wood is transported and unloaded.

[0053] For example, first, multiple electric push rods 417 all drive the sealing slider 418 to rise to the same height, and the tops of multiple wood pieces inside the grab bucket 401 are not squeezed and contacted with the elastic stop block 430 and the bottom of the limit rod 413, and when the sum of the pressure values ​​detected by the multiple pressure sensors 420 above the support plates 414 on both sides is equal, it means that the wood pieces are in a uniform position above the support plates 414, and the two support plates 414 provide stable support for the wood pieces. When the sum of the pressure values ​​detected by the multiple pressure sensors 420 on one side is greater than that on the other side, it means that the weight of the wood pieces on this side is greater than that on the other side, then the control room 105 controls the multiple electric push rods 417 on this side to start and extend the output end, and the output end of the electric push rod 417 drives the sealing slider 418 to move outward along the connecting hole 416 The sealing slider 418 drives the wood to rise on this side through the arc-shaped support grooves 419 on both sides, and the multiple electric push rods 417 on the other side of the control room 105 are started and the output ends are shortened. The output ends of the electric push rods 417 drive the sealing slider 418 to move inward along the connecting hole 416, and the sealing slider 418 drives the wood to lower on this side through the arc-shaped support grooves 419 on both sides. Then, the wood tilts above the support plates 414 on both sides and slides to the side where the pressure value detected by the pressure sensor 420 decreases, and the center of gravity of the wood synchronously moves between the two support plates 414. After that, the control room 105 controls the multiple electric push rods 417 to restart and restore the initial value, and the sealing slider 418 synchronously drives the wood to be stably located above the support plates 414 for elastic fixed support.

[0054] Afterwards, the electric push rod 417 starts and drives the sealing slider 418 to move upward along the connecting hole 416 to the same height. The arc-shaped support grooves 419 on both sides of the sealing slider 418 apply extrusion force to the bottom of the wood, thereby ensuring that the tops of multiple wood inside the grab bucket 401 are squeezed and contacted with each other with the limit rod 413 and the bottom of the elastic stop block 430. When the volume of wood at a certain position above the support plate 414 on the same side is large, the pressure value detected by the pressure sensor 420 increases and is greater than the set pressure preset value. In order to ensure that the wood can be stably supported above the support plate 414, the control room 105 controls the electric push rod 417 there to start and shorten the output end. The output end of the electric push rod 417 drives the sealing slider 418 to move inward along the connecting hole 416, and the arc-shaped support grooves 419 on this side of the sealing slider 418 reduce the supporting force of the wood to the optimal level. The pressure value detected by the pressure sensor 420 reaches the set pressure value, and the wood can be stably supported and limited.

[0055] And when the sealing slider 418 moves inward along the connecting hole 416, the sealing slider 418 synchronously drives the follower plates 421 on both sides to move, and the follower plates 421 on both sides drive the matching holes 422 to move, and the overlapping area of ​​the matching holes 422 and the docking holes 423 increases. The amount of gas discharged to both sides along the overlapping area of ​​the matching holes 422 and the docking holes 423 in the air vent 415 increases. The increased amount of gas not only exerts wind force on the moving scraper 425 and drives the moving scraper 425 to stretch the connecting spring 424 to move away from the support plate 414, but also the increased amount of gas can perform wind cleaning on the wood on the larger side, thereby improving the scraping and recovery cleaning effect of impurities dropped from the wood, and ensuring the stable cleaning and recovery quality of the wood inside the grab bucket 401.

[0056] After the wood is grabbed and fixed, the control room 105 controls the rotating motor 407 to start and drive the active gear 408 to rotate. The active gear 408 and the rotating gear 405 mesh with each other and drive the fixed frame 403 to rotate. The fixed frame 403 drives the grabbing buckets 401 on both sides to rotate, and the grabbing buckets 401 drive the wood inside to rotate, thereby further realizing the transportation effect of the wood.

[0057] And during the transportation process, due to the centrifugal force exerted on the wood, the wood will move laterally inside the grab bucket 401. Since the outer surface of the wood is not uniform, when the wood moves laterally above the support plate 414, the pressure value detected by the pressure sensor 420 changes. At this time, regardless of whether the pressure value detected by the pressure sensor 420 increases or decreases, the control room 105 controls the electric push rod 417 to start and the output end to extend. The output end of the electric push rod 417 drives the sealing slider 418 to move outward along the connecting hole 416. The arc-shaped support grooves 419 on both sides of the sealing slider 418 drive the wood to move upward. The wood further improves its own clamping stability under the elastic support of the limit rods 413 on both sides and the elastic block 430 on the top, effectively avoiding the centrifugal separation of the grab bucket 401 during the transportation of the wood, and ensuring that the wood can be transported stably and accurately.

[0058] Afterwards, when the grab bucket 401 moves to the top of the vehicle and needs to be unloaded, the control room 105 first controls the air blower 427 to stop working, and the hydraulic clamping rods 429 on both sides are started and the output ends are shortened, and the output ends of the hydraulic clamping rods 429 drive the limit rod 413 to move away from each other around the rotating rod 402, and the limit rod 413 simultaneously drives the grab buckets 401 on both sides to slowly rotate away from each other, and in the rotation process, the wood in the middle position continuously slides down to the top of the vehicle under the action of gravity, and the pressure value detected by the pressure sensor 420 on the side wall of the arc-shaped support groove 419 close to the fixed frame 403 side continues to decrease, and when the pressure value detected by the pressure sensor 420 on the side of the fixed frame 403 is zero, and the pressure on the other side is zero, the pressure on the side wall is zero. When the pressure value detected by the pressure sensor 420 is not zero, it means that the wood on the side close to the fixed frame 403 has been unloaded, and the control room 105 controls the electric push rod 417 on this side to start and the output end is shortened to the initial value. The electric push rod 417 moves downward to a distance and retracts into the connecting hole 416. The arc-shaped support groove 419 on the side wall of the sealing slider 418 is separated from the arc-shaped support for the wood, and under the action of the gravity of the wood, it continuously slides downward along the support plate 414 to the top of the vehicle, thereby completing the unloading process of the sealing slider 418 on this side. The above process is repeated continuously to realize the layer-by-layer unloading of the wood inside the grab bucket 401, thereby ensuring the unloading quality and effectively avoiding the accumulation of wood during the unloading process and reducing the safety and stability of the vehicle.

[0059] After the unloading of the wood is completed, the grab bucket 401 is moved and separated from the top of the vehicle. At this time, the sealing slider 418 drives the follower plates 421 on both sides to move downward to the minimum value, and the overlapping area of ​​the matching hole 422 and the docking hole 423 reaches the maximum value. The control room 105 controls the blower 427 to start and pass gas into the vent hole 415. The gas is discharged to both sides along the vent hole 415, the matching hole 422 and the docking hole 423. The gas not only applies thrust to the side wall of the moving scraper 425 and enables the moving scraper 425 to scrape and clean the inner wall of the grab bucket 401, but also can clean the inner wall of the grab bucket 401 by wind under the action of the wind, so that the impurities attached to the inner wall of the grab bucket 401 are evenly discharged along the opening, and the impurities blocked in the discharge hole 411 can also be discharged downward in the opposite direction, thereby avoiding impurities from contaminating the subsequent grabbing of wood.

[0060] Then, the grab bucket 401 is moved to above the subsequent wood, and the above process is repeated to grab the subsequent wood, rotate it to above the vehicle and recover it.

[0061] The dual-power hydraulic drive system is easy to operate, safe and stable, reduces labor intensity, improves work efficiency, reduces production costs, expands the scope of operation, realizes non-stop maintenance operations, and further improves the efficiency and effect of grabbing wood; and the grab bucket 401 can also realize all-round elastic grabbing of wood during the grabbing process of wood, improve the wrapping and fixing effect of wood, and after the grabbing is completed, it can use the high-frequency vibration of the wood to realize the clean recovery of impurities attached to the outer surface of the wood, and cooperate with the reciprocating high-frequency movement of the moving scraper 425 and the wind force discharged from the docking hole 423 to effectively improve the quality of wood recovery and avoid pollution to the normal grabbing of subsequent wood; and after the grabbing of wood is completed, the wood is adjusted in two The position between the support plates 414 ensures the stability and accuracy of the center of gravity of the wood, avoiding the wood from shaking and lowering and causing damage to the grab bucket 401 when the wood is rotated later; at the same time, during the grabbing and transporting process of the wood, the pressure value change detected by the pressure sensor 420 corresponds to the support force of the arc-shaped support groove 419 on the side wall of the sealing slider 418 on the side wall of the wood, further ensuring the stability and accuracy of the wood above the support plate 414; after the grab bucket 401 transports the wood to the top of the vehicle, multiple sealing sliders 418 move in the opposite direction in turn and realize the uniform discharge of the wood layer by layer, effectively ensuring the uniformity and stability of the wood recovery, avoiding the accumulation of multiple woods and causing damage to the vehicle or wood.
