Description

Technical Field

[0001] This invention relates to the field of pallet load dynamic balance control system technology, specifically a pallet load dynamic balance control system. Background Technology

[0002] In industrial handling, due to different stacking methods and types of goods, the center of gravity of the goods may not be on the longitudinal center line of the pallet. It is impossible to adjust according to the real-time stacking situation of the goods, making it difficult for the pallet, which was originally fixed, to maintain its balance and easily tilt, causing the objects to shift or tip over.

[0003] With the development of the logistics industry, the logistics and transportation of high-precision equipment is becoming more and more routine. However, such equipment has very high requirements for vibration coefficient during transportation. The stress state and tilt state will directly affect the vibration index. If the top surface of the pallet is not level, it may cause damage to the precision equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a pallet load dynamic balance control system, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pallet load dynamic balance control system, comprising a cross-shaped base frame and a load pallet, wherein a support frame is fixed at the end of the cross-shaped base frame away from the center, the load pallet is placed on the arc surface of the support frame, a control device is provided above the cross-shaped base frame to facilitate automatic balancing of gravity when the load pallet is subjected to uneven force, and an auxiliary device is provided below the load pallet to assist in resetting the load pallet after balancing gravity. The control device includes a force-bearing block, a push rod, a slide rail, a counterweight, and a rubber ring. The force-bearing block is slidably connected to the side wall of the support frame near the cross base. The push rod is slidably connected to the upper surface of the cross base. The slide rail is fixedly connected to the bottom surface of the cargo tray. When the cargo tray tilts downward, it pushes the force-bearing block downward to slide.

[0006] According to the above technical solution, the counterweight is slidably connected to the bottom surface of the cargo tray, and a protrusion is fixed on the upper surface of the counterweight. The protrusion on the upper surface of the counterweight is slidably connected to the inner wall of the slide rail.

The connecting plate is fixedly connected to the side wall of the force-bearing block, and the push block is fixedly connected to the bottom surface of the connecting plate. When the force-bearing block slides downward, it drives the connecting plate to move downward as well.

[0008] According to the above technical solution, the hollow block is fixedly connected to the side wall of the cross base frame, the outer wall of the push block is in contact with the inner wall of the hollow block, the hollow tube is fixedly connected to the side wall of the hollow block, the hollow tube is connected to the hollow block, the top rod passes through the end of the hollow tube away from the hollow block, and is slidably connected at the penetration point.

[0010] According to the above technical solution, a protrusion is fixed on the upper surface of the extrusion rod, and the outer wall of the protrusion of the extrusion rod is slidably connected to the inner wall of the sliding groove. The support rod passes through the bottom surface of the limiting block and is slidably connected at the penetration point. The blocking plate is fixedly connected to the upper surface of the support rod, and the outer wall of the blocking plate is slidably connected to the inner wall of the limiting block. When the counterweight slides to the extrusion rod, it pushes the extrusion rod to slide.

[0011] According to the above technical solution, the side wall of the cross base frame is provided with a fixing device to prevent the equipment from tipping over. The fixing device includes a pressing block, a pressure plate, a return spring, a sliding plate and a reinforcing rod. The pressing block penetrates the upper surface of the cross base frame and is slidably connected at the penetration point. When the push rod slides to the pressing block, it pushes the pressing block to slide downward.

[0012] According to the above technical solution, the pressure plate is fixedly connected to the bottom surface of the extrusion block, the pressure plate passes through the center of the cross base frame and is slidably connected at the penetration point, one end of the reset spring is fixedly connected to the bottom surface of the pressure plate, and the reset spring is compressed when the pressure plate slides downward.

[0014] This invention provides a dynamic balance control system for pallet load. It has the following beneficial effects: (1) The present invention is equipped with a control device. When the load tray is unevenly stressed and one side tilts downward, the counterweight block is pushed to slide away from the end of the load tray that is stressed more, in conjunction with the force block, push rod and slide rail. This allows the load tray to automatically increase pressure on the tilted end when it is tilted, thereby avoiding the load tray being stressed more on one end and less on the other end, which would cause the load tray to tilt continuously and tip over. This solves the problem that items suddenly placed on the load tray can easily cause uneven stress and tipping of the load tray. A rubber ring is used to pad between the load tray and the support frame, which further increases the friction between the load tray and the support frame. This prevents the load tray from tilting too quickly when stressed, which would cause the device to react too slowly and thus make it difficult to provide effective protection. This solves the problem that the device may react too slowly when the load tray is tilted.

[0015] (2) The present invention is equipped with an auxiliary device. When the weight of the counterweight is insufficient to balance the pallet, the top rod is pushed out in conjunction with the connecting plate, push block, hollow block, hollow tube and sealing plate to provide further support to the pallet on both sides of the downward tilting end. This prevents the pallet from tilting and tipping over due to insufficient weight of the counterweight, and solves the problem that the weight of the counterweight may be too light to balance all the placed items. When the weight of the counterweight is much greater than the weight of the items on the side of the pallet that was originally under greater weight, the support rod is pushed out in conjunction with the limiting block, sliding groove, squeezing rod and blocking plate to add a support point to the pallet on one side of the counterweight, improve the support effect of the pallet, and prevent the pallet from tipping over in the opposite direction due to the weight of the counterweight being much greater than the placed items when balancing the pallet. This solves the problem that the weight of the counterweight may be too heavy and cause the pallet to tip over in the opposite direction.

[0016] (3) The present invention is equipped with a fixing device. When the cargo tray tilts under gravity, the push rod pushes the squeezing block to slide downward, so that the squeezing block slides into the retracted cross base frame, lowering the center of gravity of the cross base frame and further improving the fit between the cross base frame and its placement surface. This reduces the vibration of the cross base frame caused by the movement of the cargo tray, and avoids the displacement of the items on the cargo tray caused by the shaking of the cross base frame, which would affect the balance of the cargo tray again. This solves the problem that the shaking of the cross base frame may cause the items to be displaced. While lowering the center of gravity of the cross base frame, the pressure plate, return spring, sliding plate and reinforcing rod form multiple sets of stable triangles on the side wall of the cross base frame to clamp and fix the cross base frame, and further support it, thereby preventing the cross base frame from tipping over due to the influence of the cargo tray. This solves the problem that the cross base frame may tip over when the cargo tray is under too much gravity. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 One embodiment of the present invention is: a pallet load dynamic balance control system, including a cross base frame 1 and a loading pallet 3. A support frame 2 is fixed at the end of the cross base frame 1 away from the center. The loading pallet 3 is placed on the arc surface of the support frame 2. When the items placed on the loading pallet 3 pile up on one side, causing uneven force on the loading pallet 3, one side of the loading pallet 3 tilts downward. The bottom edge of the downward tilting side of the loading pallet 3 slides downward along the arc surface of the support frame 2. A control device is provided above the cross base frame 1 to facilitate automatic balance of gravity when the loading pallet 3 is subjected to uneven force.

[0021] The control device includes a force-bearing block 41, a push rod 42, a slide rail 43, a counterweight 44, and a rubber ring 45. The force-bearing block 41 is slidably connected to the side wall of the support frame 2 near the cross base frame 1. When the side of the load-bearing tray 3 with greater weight slides down to the force-bearing block 41, the bottom edge of the load-bearing tray 3 pushes the force-bearing block 41 downward. The push rod 42 is slidably connected to the upper surface of the cross base frame 1. When the force-bearing block 41 slides down to the push rod 42, the side of the force-bearing block 41 slides against the inclined surface of the push rod 42, and the force-bearing block 41 pushes the push rod 42 towards the center of the cross base frame 1. The slide rail 43 is fixedly connected to the bottom surface of the carrying tray 3, and the counterweight 44 is slidably connected to the bottom surface of the carrying tray 3. A protrusion is fixed to the upper surface of the counterweight 44, and the protrusion is slidably connected to the inner wall of the slide rail 43. As the carrying tray 3 tilts, the counterweight 44 also tilts. The side wall of the counterweight 44 closer to the heavier end of the carrying tray 3 is lower, and the side wall further away from the heavier end of the carrying tray 3 is higher. When the push rod 42 slides to the counterweight 44, it impacts the side wall of the counterweight 44, pushing the counterweight 44 along... The slide rail 43 slides away from the end of the load-bearing tray 3 where the weight is greater, and the counterweight 44 slides away from the end of the load-bearing tray 3 where the weight is greater to balance the weight of the load-bearing tray 3, thereby preventing the load-bearing tray 3 from tipping over due to excessive weight on one side. The rubber ring 45 is fixedly connected to the connection between the side wall and the bottom surface of the load-bearing tray 3. The outer wall of the rubber ring 45 fits against the arc surface of the support frame 2. The load-bearing tray 3 contacts the support frame 2 through the rubber ring 45. The rubber ring 45 increases the friction between the load-bearing tray 3 and the support frame 2, slowing down the sliding speed of the load-bearing tray 3 on the arc surface of the support frame 2. The control device improves the response speed of the control device relative to the tilt of the carrying tray 3. When the carrying tray 3 is under uneven force and one side tilts downward, the control device works with the force block 41, push rod 42 and slide rail 43 to push the counterweight block 44 to slide away from the end of the carrying tray 3 with greater force. This allows the carrying tray 3 to automatically increase pressure on the tilted end when it is tilted, thereby avoiding the carrying tray 3 from being under greater weight on one end and less weight on the other end, which would cause the carrying tray 3 to continue to tilt and tip over. This solves the problem that items suddenly placed on the carrying tray 3 can easily cause the carrying tray 3 to tip over due to uneven force. A rubber ring 45 is used to pad between the cargo tray 3 and the support frame 2, which further increases the friction between the cargo tray 3 and the support frame 2. This prevents the cargo tray 3 from tilting too quickly when under force, which would cause the device to react too slowly and thus make it difficult to provide effective protection. This solves the problem that the device may react too slowly when the cargo tray 3 is tilted.

[0022] In this embodiment, when items pile up on one side of the pallet 3, causing uneven force on the pallet 3, one side of the pallet 3 tilts downwards. The bottom edge of the tilted side of the pallet 3 slides downwards along the arc surface of the support frame 2. When the side of the pallet 3 with greater weight slides down to the force block 41, the bottom edge of the pallet 3 pushes the force block 41 downwards. When the force block 41 slides down to the push rod 42, the side of the force block 41 slides against the inclined surface of the push rod 42, pushing the push rod 42 towards the center of the cross base 1. Due to the tilt of the pallet 3, the counterweight 44 also tilts, and the counterweight 44 moves closer to the side of the pallet 3 with greater weight. The sidewalls are lower, while the sidewall of the counterweight 44, which is farther from the load-bearing end of the pallet 3, is higher. When the push rod 42 slides to the counterweight 44, it impacts the sidewall of the counterweight 44, pushing the counterweight 44 to slide along the slide rail 43 away from the load-bearing end of the pallet 3. The sliding of the counterweight 44 away from the load-bearing end of the pallet 3 balances the gravity on the pallet 3, thereby preventing the pallet 3 from tipping over due to excessive gravity on one side. The pallet 3 contacts the support frame 2 through the rubber ring 45. The rubber ring 45 increases the friction between the pallet 3 and the support frame 2, slowing down the sliding speed of the pallet 3 on the arc surface of the support frame 2 and improving the response speed of the control device relative to the tilt of the pallet 3.

[0023] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, an auxiliary device is provided below the cargo tray 3 to assist in resetting the cargo tray 3 after balancing gravity. The auxiliary device includes a connecting plate 51, a push block 52, a hollow block 53, a hollow tube 54, a top rod 55, a sealing plate 56, a limiting block 57, a sliding groove 58, a pressing rod 59, a support rod 510, and a blocking plate 511. The connecting plate 51 is fixedly connected to the side wall of the force-bearing block 41. When the force-bearing block 41 slides downward, it drives the connecting plate 51 to slide downward as well. The push block 52 is fixedly connected to the bottom surface of the connecting plate 51. When the connecting plate 51 slides downward, it drives the push block 52 to move downward as well. The hollow block 53 is fixedly connected to the side wall of the cross base frame 1. The outer wall of the push block 52 is in contact with the inner wall of the hollow block 53. When push block 52 moves downward to hollow block 53, it inserts into hollow block 53 through the opening on the upper surface of hollow block 53. Push block 52 continues to slide downward against the inner wall of hollow block 53, compressing the air inside hollow block 53. Hollow tube 54 is fixedly connected to the side wall of hollow block 53. After being compressed, the air flows from hollow block 53 into hollow tube 54. Hollow tube 54 is connected to hollow block 53. Top rod 55 passes through the end of hollow tube 54 away from hollow block 53 and is slidably connected at the penetration point. When top rod 55 extends out of hollow tube 54, it supports the cargo tray 3 on both sides of the cross base 1, providing additional support points for cargo tray 3. Sealing plate 56 is fixedly connected to the bottom surface of top rod 55. When sealing plate 56 slides upward, it drives top rod 55 upward as well. As the sliding mechanism advances, the sealing plate 56 pushes the push rod 55 out of the hollow tube 54. The outer wall of the sealing plate 56 fits against the inner wall of the hollow tube 54. Because the sealing plate 56 fits tightly against the inner wall of the hollow tube 54, it seals the end of the hollow tube 54 away from the hollow block 53. Therefore, when air is forced into the hollow tube 54, it pushes the sealing plate 56 upward to slide. The limiting block 57 is fixedly connected to the bottom surface of the carrying tray 3. The sliding groove 58 is opened on the bottom surface of the carrying tray 3. The pressing rod 59 passes through the side wall of the limiting block 57 and is slidably connected at the penetration point. A protrusion is fixed on the upper surface of the pressing rod 59. The outer wall of the protrusion of the pressing rod 59 is slidably connected to the inner wall of the sliding groove 58. The counterweight block 44 is impacted by the push rod 42 and slides towards the end of the carrying tray 3 away from the end with greater weight, towards the pressing rod. At position 59, the counterweight 44 slides to the pressing rod 59, pushing the pressing rod 59 towards the limiting block 57. When the pressing rod 59 slides to the limiting block 57, it inserts into the opening on the side wall of the limiting block 57 and continues to slide. The support rod 510 passes through the bottom surface of the limiting block 57 and is slidably connected at the penetration point. The blocking plate 511 is fixedly connected to the upper surface of the support rod 510. When the blocking plate 511 slides downward, it drives the support rod 510 to slide downward as well, causing the support rod 510 to extend and contact the placement surface of the cross base frame 1, further supporting the cargo tray 3 and preventing the cargo tray 3 from tipping over in the opposite direction due to excessive weight of the counterweight 44. The outer wall of the blocking plate 511 is slidably connected to the inner wall of the limiting block 57.When the pressing rod 59 slides to the blocking plate 511, the inclined surface of the pressing rod 59 slides against the side of the blocking plate 511, pushing the blocking plate 511 downwards. When the weight of the counterweight 44 is insufficient to balance the pallet 3, this auxiliary device, in conjunction with the connecting plate 51, push block 52, hollow block 53, hollow tube 54, and sealing plate 56, pushes out the top rod 55, providing further support to the pallet 3 on both sides of the downward-sloping end. This prevents the pallet 3 from tipping over due to insufficient weight of the counterweight 44, thus solving the problem that the counterweight 44 may be too light to balance all placed items. When the weight of the counterweight 44 is much greater than the weight of the items on the side of the load-bearing tray 3 that was originally under greater weight, the support rod 510 is pushed out in conjunction with the limiting block 57, the sliding groove 58, the squeezing rod 59 and the blocking plate 511. This adds a support point to the load-bearing tray 3 on one side of the counterweight 44, improves the support effect of the load-bearing tray 3, and prevents the load-bearing tray 3 from tipping over in the opposite direction due to the weight of the counterweight 44 being much greater than the weight of the items placed on it. This solves the problem that the weight of the counterweight 44 may be too heavy and cause the load-bearing tray 3 to tip over in the opposite direction.

[0024] The side wall of the cross-shaped base frame 1 is equipped with a fixing device to prevent the equipment from tipping over. The fixing device includes a pressing block 61, a pressure plate 62, a return spring 63, a sliding plate 64, and a reinforcing rod 65. The pressing block 61 penetrates the upper surface of the cross-shaped base frame 1 and is slidably connected at the penetration point. When the push rod 42 slides to the pressing block 61, the side of the push rod 42 slides against the inclined surface of the pressing block 61, pushing the pressing block 61 downward. The pressure plate 62 is fixedly connected to the bottom surface of the pressing block 61. When the pressing block 61 slides downward, it retracts into the cross-shaped base frame 1, causing the center of gravity of the cross-shaped base frame 1 to shift downward. The pressure plate 62 penetrates the center of the cross-shaped base frame 1 and is slidably connected at the penetration point. When the pressing block 61 slides downward, it pushes the pressure plate 62 downward as well. One end of the return spring 63 is fixedly connected to the bottom surface of the pressure plate 62. When the pressure plate 62 slides downward... When sliding, the return spring 63 is compressed. The other end of the return spring 63 is fixedly connected to the inner wall of the cross base 1. The sliding plate 64 is slidably connected to the side wall of the cross base 1 and fixedly connected to the bottom surface of the pressure plate 62. When the pressure plate 62 slides downward, it also drives the sliding plate 64 to slide downward. The reinforcing rod 65 is hinged to the bottom surface of the sliding plate 64. When the sliding plate 64 slides downward, it also drives the hinge point between the sliding plate 64 and the reinforcing rod 65 to move downward. The end of the reinforcing rod 65 away from the sliding plate 64 is in contact with the placement surface and cannot continue to move downward. Therefore, the end of the reinforcing rod 65 away from the sliding plate 64 can only slide in the horizontal direction. When the hinge point between the sliding plate 64 and the reinforcing rod 65 moves downward, the reinforcing rod 65 itself also rotates. When the reinforcing rod 65 rotates, the reinforcing rod 65... The sliding plate 64 forms a triangle with the placement surface. The triangle has stability. When the cargo tray 3 is tilted by gravity, the fixing device, together with the push rod 42, pushes the squeezing block 61 to slide downward, so that the squeezing block 61 slides into the retracted cross base 1, lowers the center of gravity of the cross base 1, and further improves the fit between the cross base 1 and its placement surface. This reduces the vibration of the cross base 1 caused by the movement of the cargo tray 3, and avoids the displacement of the items on the cargo tray 3 caused by the shaking of the cross base 1, which would affect the balance of the cargo tray 3 again. This solves the problem that the shaking of the cross base 1 may cause the items to be displaced. While lowering the center of gravity of the cross base frame 1, multiple stable triangles are formed on the side wall of the cross base frame 1 in conjunction with the pressure plate 62, the return spring 63, the sliding plate 64 and the reinforcing rod 65 to clamp and fix the cross base frame 1, and further support it, thereby preventing the cross base frame 1 from tipping over due to the influence of the cargo tray 3, and solving the problem that the cross base frame 1 may tip over when the cargo tray 3 is subjected to excessive gravity.

[0025] In this embodiment, when the counterweight 44 is impacted and slides away from the heavier end of the load-bearing tray 3, if the weight of the counterweight 44 is insufficient to balance the load-bearing tray 3, the heavier end of the load-bearing tray 3 continues to tilt downwards, pushing the force-bearing block 41 downwards. As the force-bearing block 41 slides downwards, it also causes the connecting plate 51 to slide downwards. The downward sliding of the connecting plate 51 causes the push block 52 to move downwards as well. When the push block 52 moves downwards to the hollow block 53, it inserts into the hollow block 53 through the opening on its upper surface. The air inside the hollow block 53 continues to slide downwards, compressing the air and pushing it into the hollow tube 54. Since the sealing plate 56 is tightly fitted to the inner wall of the hollow tube 54, sealing the end of the hollow tube 54 away from the hollow block 53, the air pushed into the hollow tube 54 pushes the sealing plate 56 upwards. As the sealing plate 56 slides upwards, it also drives the push rod 55 upwards. The sealing plate 56 pushes the push rod 55 out of the hollow tube 54, causing the push rod 55 to be positioned on both sides of the cross-shaped base frame 1 against the loading tray. 3. Additional support points are provided for the cargo tray 3. When the counterweight 44 is impacted and slides away from the heavier end of the cargo tray 3, if the weight of the counterweight 44 is much greater than the weight of the items on the originally heavier end of the cargo tray 3, the counterweight 44, impacted by the push rod 42, slides away from the heavier end of the cargo tray 3 to the compression rod 59, causing the cargo tray 3 to tilt in the opposite direction. When the counterweight 44 slides to the compression rod 59, it pushes the compression rod 59 towards the limiting block 57, compressing... When rod 59 slides to limit block 57, it is inserted into the opening on the side wall of limit block 57 and continues to slide. When the pressing rod 59 slides to the blocking plate 511, the inclined surface of the pressing rod 59 slides against the side of the blocking plate 511. The pressing rod 59 pushes the blocking plate 511 downward. When the blocking plate 511 slides downward, it drives the support rod 510 to slide downward as well, so that the support rod 510 extends out and contacts the placement surface of the cross base frame 1, further supporting the cargo tray 3 and preventing the cargo tray 3 from tipping over in the opposite direction due to excessive weight of counterweight block 44.

[0026] The force-bearing block 41 slides downward under the push of the load tray 3, pushing the push rod 42 to slide away from the end of the load tray 3 where the weight is greater. When the push rod 42 slides to the pressing block 61, the side of the push rod 42 slides against the inclined surface of the pressing block 61, pushing the pressing block 61 downward. As the pressing block 61 slides downward, it pushes the pressure plate 62 downward as well. When the pressure plate 62 slides downward, it compresses the return spring 63. As the pressing block 61 slides downward, it retracts into the cross base 1, causing the center of gravity of the cross base 1 to shift downward, further improving the cross base 1's alignment with its placement surface. The fit is improved to reduce vibrations caused by the movement of the pallet 3 on the cross base frame 1. When the pressure plate 62 slides downward, it also drives the sliding plate 64 to slide downward. When the sliding plate 64 slides downward, it also drives the hinge between the sliding plate 64 and the reinforcing rod 65 to move downward. The end of the reinforcing rod 65 away from the sliding plate 64 is in contact with the placement surface and cannot move further downward. Therefore, the end of the reinforcing rod 65 away from the sliding plate 64 can only slide in the horizontal direction. When the hinge point between the sliding plate 64 and the reinforcing rod 65 moves downward, the reinforcing rod 65 itself also rotates. When the reinforcing rod 65 rotates, a triangle is formed between the reinforcing rod 65, the sliding plate 64 and the placement surface. The triangle has stability and further supports the cross base frame 1 on the side to prevent the cross base frame 1 from tipping over due to the influence of the pallet 3.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
