Description

Technical Field

[0001] This application relates to the field of material handling equipment technology, and in particular to a hybrid electric dual-power material handling machine. Background Technology

[0002] With the rapid development of industrial technology, material handling machines, as important material handling equipment, play an irreplaceable role in various industrial production processes. Traditional material handling machines mostly use either fuel or electricity as a single power source, which to some extent limits their application range and efficiency. With increasing environmental awareness and the optimization of energy structures, hybrid fuel-electric dual-power material handling machines have emerged, and the demand for their functionality is also growing.

[0003] The existing technology still has the following problems:

[0004] 1. The existing material handling machine did not fully consider the stability and reliability of the equipment during the design and manufacturing process. When handling materials, the gripper cannot rotate according to the needs. It can only simply bring the gripper arm close to the material to be transported. When handling stacked materials, there are large gaps in the middle of the material after it is gripped. It is easy for the material to loosen in the gripper, resulting in unstable gripping and material falling, which increases the safety hazards of personnel and equipment.

[0005] 2. In traditional material handling machine designs, the driver's cab is usually fixed in position and lacks a corresponding lifting structure. This limits the driver's field of vision to a certain extent, leading to inaccurate handling positions and affecting the precision and safety of operation. In addition, material handling machines with a driver's cab lifting structure do not have a buffering effect when lifting, and the drop will bring a strong vibration, causing great wear and tear on the equipment. At the same time, it is difficult to detect the displacement of the driver's cab in time, thus making timely maintenance impossible.

[0006] 3. Existing material handling machines inevitably encounter bumpy road sections during material transfer, which causes the grippers to shake to a certain extent. This shaking of the material on the grippers causes wear on both the grippers and the material, reducing the service life of the grippers. At the same time, it is difficult to adjust the angle of the gripping components. Summary of the Invention

[0018] The technical solution provided in this application has at least the following technical effects or advantages:

[0019] 1. By adopting a gripping component, this invention effectively solves the problem that existing material handling machines, in their design and manufacturing process, did not fully consider the stability and reliability of the equipment. During gripping, the grippers could not rotate according to requirements, and could only simply bring the gripping arms close to move the material. This resulted in large gaps between the gripped materials, making them prone to loosening in the grippers, leading to unstable gripping, material falling, and increased safety hazards for personnel and equipment. This invention, however, allows the grippers of the gripping component to rotate according to the specifications of the material, making the materials more tightly packed. Simultaneously, it limits the top of the material, and the limiting mechanism can adaptively adjust according to the material specifications, thereby improving the stability of the material in the grippers and preventing material from falling during transport.

[0020] 2. By adopting a lifting component, this invention effectively solves the problem of traditional material handling machine designs where the cab position is mostly fixed and lacks a corresponding lifting structure. This limits the driver's field of vision to a certain extent, leading to inaccurate handling positions and affecting the precision and safety of operation. Furthermore, material handling machines with cab lifting structures do not have a buffering effect during lifting, resulting in strong vibrations when falling and causing significant wear and tear on the equipment. At the same time, it is difficult to detect cab misalignment in a timely manner, making timely maintenance impossible. This invention, through the lifting component, can adjust the height of the cab according to needs, providing the driver with a good field of vision. It also has a buffering mechanism during descent, reducing equipment wear and improving the driver's experience. Moreover, it can detect cab misalignment in a timely manner, facilitating subsequent maintenance.

[0021] 3. Due to the adoption of a buffer component, the existing material handling machine inevitably encounters bumpy sections during material transfer, which causes the grippers to shake to a certain extent. This results in material shaking on the grippers, causing wear on both the grippers and the material, reducing the service life of the grippers, and making it difficult to adjust the angle of the gripping component. The present invention reduces the shaking of the grippers on bumpy sections through the buffer component, reduces the shaking of materials caused by rapid start and stop during transfer, improves the stability of material transfer, reduces equipment wear, and extends the service life of the equipment. At the same time, it allows for adjustment of the angle of the gripping component. Attached Figure Description

[0036] For materials with large gaps after being gripped, which can easily loosen in the grippers, this invention allows the grippers of the gripping component to rotate according to the specifications of the materials, making the materials more tightly packed together. For cabs that are often fixed in position and lack corresponding lifting structures, which to some extent limits the driver's visibility, this invention uses a lifting component to adjust the height of the cab as needed, providing the driver with a better field of vision. For grippers that sway on bumpy roads, this invention uses a buffer component to reduce gripper sway on bumpy roads.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] Example

[0039] Please see Figure 1As shown, a hybrid oil-electric dual-power material grabber includes a material grabber body 1. A power mechanism 2 is provided on the upper surface of the material grabber body 1. The power mechanism 2 has two modes: diesel power and electric power. Under normal circumstances, it works independently, but it can also be switched or used in combination as needed. Diesel power mode: When there is no external power supply available to the site to ensure that the electric motor can work continuously, the diesel engine will serve as the main power source. The operator can quickly switch to diesel engine drive to ensure that the material grabber can continue to operate. Electric Power Mode: When there is a stable external power supply at the work site, in order to minimize operating costs and environmental impact, the operator of the grabber can switch to an external power supply to drive the motor to operate the entire machine. When operating in areas with strict requirements for environmental protection and noise, in order to comply with relevant regulations or reduce the impact on the surrounding environment, a lifting component 3 is provided on the upper surface of the grabber body 1. The cab 4 is fixedly installed on the upper surface of the lifting component 3. A robotic arm 5 is provided on the upper surface of the grabber body 1. A second hydraulic cylinder 6 is provided on the outer surface of the robotic arm 5. A buffer component 7 is provided at the end of the robotic arm 5 away from the grabber body 1. A gripping component 8 is provided at the bottom of the buffer component 7. The lifting component 3 is used to lift and lower to change the height of the cab 4, thereby improving the visibility of the cab 4. The operation of the second hydraulic cylinder 6 drives the robotic arm 5 to rotate, which facilitates the transfer of materials on the gripping component 8. The buffer component 7 is used to buffer during transportation and reduce bumps during the journey. The gripping component 8 is used to stably clamp the materials.

[0040] Please see Figure 2 and Figure 3As shown, the lifting assembly 3 includes a base 31, a first hydraulic cylinder 32 fixedly mounted on the upper surface of the base 31, a hydraulic rod 33 slidably connected to the inner cavity of the first hydraulic cylinder 32, a slider 34 slidably connected to the upper surface of the base 31, drive rods 35 fixedly mounted at both ends of the slider 34, limit frames 36 fixedly mounted on both sides of the base 31, a buffer mechanism 37 fixedly mounted on the upper surface of the limit frames 36, an alarm mechanism 38 provided above the limit frames 36, a support plate 310 fixedly connected to the bottom of the cab 4, lifting rods 39 fixedly mounted at the four corners of the support plate 310, a first connecting block 311 fixedly mounted at the bottom of the support plate 310, a drive groove 312 formed on the outer surface of the first connecting block 311, the lifting rod 39 and the limit frame 36 slidably connected, the drive rod 35 and the drive groove 312 slidably connected, and the two ends of the drive groove 312 are horizontally aligned in the middle. There are two tilting and buffering mechanisms 37 and two alarm mechanisms 38, located on both sides of the support plate 310. When adjusting the height of the cab 4, the operation of the first hydraulic cylinder 32 drives the hydraulic rod 33 to move. The movement of the hydraulic rod 33 drives the slider 34 to slide on the base 31. The sliding of the base 31 drives the drive rod 35 to move in the inner cavity of the drive groove 312, thereby driving the first connecting block 311 to move. At this time, the first connecting block 311 drives the support plate 310 to move, and the lifting rod 39 moves in the inner cavity of the limit frame 36, thereby changing the height of the cab 4 and giving the cab 4 a good view. The buffering mechanism 37 is used to buffer when the cab 4 is lowered, so that the staff in the cab 4 can have a good experience and reduce the wear and tear on the equipment. At the same time, the alarm mechanism 38 can sound an alarm when the cab 4 deviates, reminding the staff to perform maintenance.

[0041] Please see Figure 2 and Figure 4As shown, the buffer mechanism 37 includes a buffer frame 371, a fixing rod 372 fixedly installed on the inner wall of the buffer frame 371, a first spring 373 sleeved in the middle of the fixing rod 372, a sliding sleeve 374 slidably connected to the outer surface of the fixing rod 372, the sliding sleeve 374 being located at both ends of the first spring 373, a connecting strip 375 rotatably connected to the upper surface of the sliding sleeve 374, and a buffer plate 376 rotatably connected to the upper surface of the connecting strip 375. The alarm mechanism 38 includes a connecting plate 381, a first threaded rod 382 rotatably connected to the inner cavity of the connecting plate 381. The two ends of the 2 have opposite thread directions. The lower surface of the connecting plate 381 has a groove 383. The inner cavity of the groove 383 is slidably connected to an adjusting block 384. The two ends of the adjusting block 384 and the first threaded rod 382 are connected by threads. The position of the adjusting block 384 can be adjusted as needed. An alarm 385 is provided on the outer surface of the connecting plate 381. Buttons 386 are provided at both ends of the buffer frame 371. Buttons 386 and alarm 385 are electrically connected. Pressing button 386 will cause alarm 385 to sound. The outer side of the adjusting block 384 near button 386... The surface is inclined and the bottom is narrow, so that when the adjusting block 384 descends, the offset of the cab 4 can cause the adjusting block 384 to press against the button 386. The connecting plate 381 and the support plate 310 are fixedly connected. When the cab 4 descends, it causes the support plate 310 to descend as well. At this time, the connecting plate 381 moves closer to the buffer plate 376, causing the buffer plate 376 to be compressed. The compression of the buffer plate 376 causes the connecting bar 375 to rotate. The rotation of the connecting bar 375 causes the sliding sleeve 374 to move on the fixed rod 372. The movement of the sliding sleeve 374 drives the first spring 37 3. When squeezed by the sliding sleeve 374, the elastic force of the first spring 373 reduces the shaking of the cab 4 when it descends, thereby reducing the wear of the equipment and improving its service life. When the cab 4 deviates, the adjusting block 384 and the button 386 come into contact, causing the button 386 to be pressed, which triggers the alarm 385 to sound an alarm and remind the staff to perform maintenance. The first threaded rod 382 is used to adjust the position of the adjusting block 384 on the connecting plate 381, so that the position of the adjusting block 384 can be adjusted so that the adjusting block 384 and the button 386 do not come into contact when the cab 4 is not deviating.

[0042] Please see Figure 5 , Figure 6 and Figure 7As shown, the buffer assembly 7 includes a buffer block 71, with buffer rods 72 fixedly installed at both ends of the buffer block 71. A second spring 73 is sleeved on the outer surface of the buffer rods 72. A fixing block 74 is fixedly installed on the upper surface of the gripper 81. The buffer rods 72 and the fixing block 74 are slidably connected. The second spring 73 is located between the buffer block 71 and the fixing block 74. A steering mechanism 75 is provided at the end of the robotic arm 5 away from the main body 1 of the gripper. A first connecting rod 77 is fixedly installed on the upper surface of the buffer block 71. A rotating cylinder 76 is slidably connected to the outer surface of the first connecting rod 77. A connecting ring 78 is fixedly installed on the upper surface of the first connecting rod 77. The connecting ring 78 fits into the inner cavity of the rotating cylinder 76. The outer surface of the first connecting rod 77 is sleeved with... A third spring 79 is connected, located between the connecting ring 78 and the inner wall of the rotating cylinder 76. A second connecting block 710 is fixedly installed on the outer surface of the rotating cylinder 76, and an insert rod 711 is fixedly installed on the lower surface of the second connecting block 710. The insert rod 711 and the buffer block 71 are slidably connected, and there is a gap between the buffer blocks 71 and the buffer block 71. The steering mechanism 75 includes a first cylinder 751, which is fixedly connected to the robotic arm 5. A first piston rod 752 is slidably connected to the inner cavity of the first cylinder 751. A rack 753 is fixedly installed at the end of the first piston rod 752 away from the first cylinder 751. A limit block 754 is fixedly installed on the lower surface of the robotic arm 5. The rack 753 and the limit block 754 are also fixedly connected. A sliding connection is used, with a gear ring 755 fitted onto the upper surface of the rotating cylinder 76. The gear ring 755 meshes with the rack 753. The top of the rotating cylinder 76 is rotatably connected to the robotic arm 5. When the main body 1 of the material handling machine runs on a bumpy section, the gripping component 8 shakes. The shaking of the gripping component 8 causes the fixed block 74 to shake, which in turn causes the first connecting rod 77 to shake within the rotating cylinder 76. At this time, the connecting ring 78 compresses the third spring 79. The elastic force of the third spring 79 reduces the shaking of the gripping component 8 on bumpy sections. Furthermore, when the gripping component 8 is in the direction of the robotic arm 5, the elastic force of the second spring 73 keeps the buffer block 71 between the fixed blocks 74, reducing the impact of sudden stops or other operations of the robotic arm 5 during transport on the gripping component 8. The inertial force generated by the material provides a certain buffering effect when the robotic arm 5 transfers the material and the main body 1 of the gripper moves. The steering mechanism 75 is used to adjust the angle of the gripper 8 so that the material on the gripper 8 can be smoothly lowered as needed. The operation of the first cylinder 751 drives the first piston rod 752 to move. The movement of the first piston rod 752 drives the rack 753 to move. The movement of the rack 753 drives the gear ring 755 to rotate. The rotation of the gear ring 755 drives the rotating cylinder 76 to rotate. Thus, under the limit of the second connecting block 710 and the insert rod 711, the gripper 8 rotates, thereby adjusting the gripping and unloading direction of the gripper 8.

[0043] Please see Figure 8 and Figure 9As shown, the gripping assembly 8 includes a gripping frame 81. Grip arms 82 are slidably connected to both ends of the inner wall of the gripping frame 81. A second threaded rod 83 is rotatably connected to the inner wall of the gripping frame 81. A motor 84 is mounted on the outer surface of the gripping frame 81. The output end of the motor 84 is sleeved with the second threaded rod 83. Drive sleeves 85 are sleeved on both ends of the second threaded rod 83. The drive sleeves 85 and the gripping arms 82 are fixedly connected. The threads at both ends of the second threaded rod 83 are in opposite directions. A rotating mechanism 86 is mounted on the outer surface of the gripping arms 82. A clamping mechanism 87 is mounted on the top and bottom walls of the gripping frame 81. The bottom end of the rotating mechanism 86 is fixedly connected to... The device has grippers 88. When gripping materials, the operation of the motor 84 drives the second threaded rod 83 to rotate. The rotation of the second threaded rod 83 drives two drive sleeves 85 to move towards each other on the second threaded rod 83. At this time, the drive sleeves 85 drive the gripping arms 82 to move. The movement of the gripping arms 82 causes the grippers 88 to move closer together, which facilitates the gripping of materials. The rotating mechanism 86 is used to adjust the angle of the grippers 88, which can be adjusted according to the needs to make the gripped materials in close contact. The clamping mechanism 87 is used to limit the material on the grippers 88, making the material more stable during the transfer process.

[0044] Please see Figure 10 and Figure 11 As shown, the rotating mechanism 86 includes a second cylinder 861, which is fixedly connected to a clamping arm 82. A second piston rod 862 is slidably connected to the inner cavity of the second cylinder 861. A connecting seat 863 is fixedly installed at the end of the second piston rod 862 away from the second cylinder 861. A rotating bar 864 is provided in the inner cavity of the clamping arm 82. A connecting groove 865 is opened at one end of the rotating bar 864. The connecting seat 863 and the connecting groove 865 are slidably connected. A rotating rod 866 is fixedly sleeved at the end of the rotating bar 864 away from the connecting seat 863. The rotating rod 866 is rotatably connected to the clamping arm 82. Rotating connecting arms 867 are fixedly connected to both ends of the rotating rod 866. The rotating connecting arms 867 are fixedly connected to the grippers 88. The operation of 861 drives the second piston rod 862 to move. The movement of the second piston rod 862 drives the connecting seat 863 to move. The movement of the connecting seat 863 causes the connecting seat 863 to slide in the inner cavity of the connecting groove 865. At the same time, it drives the rotating bar 864 to rotate. That is, the rotation of the rotating bar 864 drives the rotating rod 866 to rotate in the inner cavity of the clamping arm 82. The rotation of the rotating rod 866 drives the rotating connecting arm 867 to rotate. The rotation of the rotating connecting arm 867 drives the gripper 88 to rotate. That is, after the gripper 88 grabs the material, the rotating mechanism 86 drives the gripper 88 to rotate, making the material more compact and the gripping more stable. At the same time, the angle adjustment of the gripper 88 improves the versatility and adaptability of the gripper 88.

[0045] Please see Figure 9 , Figure 12 and Figure 13As shown, the clamping mechanism 87 includes a pressure plate 871. A third cylinder 872 is fixedly installed on the top and bottom walls of the clamping frame 81. A third piston rod 873 is slidably connected to the inner cavity of the third cylinder 872. The third piston rod 873 and the pressure plate 871 are fixedly connected. An adjustment groove 874 is provided at the bottom end of the pressure plate 871. A third threaded rod 875 is rotatably connected to the inner cavity of the pressure plate 871. A belt 876 is sleeved on the outer surface of the third threaded rod 875. A protrusion is provided on the outer surface of the third threaded rod 875, and a groove is provided on the outer surface of the belt 876. The protrusion and the groove engage, facilitating the rotation of one third threaded rod 875 to drive the other two third threaded rods 875 to rotate. A limit mechanism 877 is slidably connected to the inner cavity of the adjustment groove 874. 6. The limiting mechanism 877 is sleeved with the third threaded rod 875. The threads at both ends of the third threaded rod 875 are in opposite directions, and the middle part of the third threaded rod 875 has no threads. The limiting mechanism 877 includes a connecting plate 8771. A floating ball 8772 is movably connected to the bottom end of the connecting plate 8771. A storage rod 8773 is fixedly installed on the lower surface of the connecting plate 8771. A telescopic rod 8774 is slidably connected to the inner cavity of the storage rod 8773. A fourth spring is provided in the inner cavity of the storage rod 8773. The telescopic rod 8774 and the fourth spring are elastically connected. A second connecting rod 8775 is fixedly installed on the outer surface of the floating ball 8772. A limiting plate 8776 is fixedly installed at the end of the second connecting rod 8775 away from the floating ball 8772. The outer surfaces of the telescopic rod 8774 and the limiting plate 8776 are... The surfaces are tightly fitted together. A spring rod 8777 is slidably connected to the outer surface of the limiting disc 8776. A fifth spring is installed inside the limiting disc 8776. The spring rod 8777 and the fifth spring are elastically connected. After the gripper 88 clamps the material, the operation of the third cylinder 872 drives the third piston rod 873 to move. The movement of the third piston rod 873 drives the pressure plate 871 to move towards the material. At this time, the bottom end of the limiting mechanism 877 is in contact with the material, limiting the material and preventing it from loosening. Simultaneously, the spacing of the limiting mechanism 877 can be adjusted in advance according to the amount of material clamped each time. By rotating the third threaded rod 875, the belt 876 rotates, causing the limiting mechanism 877 on the adjusting groove 874 to move, thereby limiting the material. Mechanism 877 can deform according to the shape of the material. For example, when gripping wood, the gripper 88 can rotate according to the specifications of the wood, making the wood gripped more tightly. At the same time, a limiting mechanism 877 is used for limiting, and the wood outer surface bending limiting mechanism 877 can adaptively adjust according to the size and curvature of the wood. That is, when the elastic rod 8777 is under pressure according to the shape of the material, the fifth spring contracts. The elastic rod 8777 is housed in the inner cavity of the limiting plate 8776 under pressure. At the same time, the limiting plate 8776 shifts as the pressure plate 871 moves down and the elastic rod 8777 contacts the material. At this time, the floating ball 8772 rotates in the inner cavity of the connecting plate 8771. The rotation of the floating ball 8772 causes the second connecting rod 8775 to tilt.This allows the limiting disc 8776 to fully conform to the material, and the telescopic rod 8774, under the elastic force of the fourth spring, keeps the limiting disc 8776 stable. Combined with the adjustment of the third threaded rod 875 and the rotation of the gripper 88, it can stably grip the material according to its specifications, improving safety during material transfer.

[0046] In summary, the lifting assembly 3 is used to raise and lower the cab 4, thereby improving the cab 4's visibility. The operation of the second hydraulic cylinder 6 drives the robotic arm 5 to rotate, facilitating the transfer of materials on the gripping assembly 8. The buffer assembly 7 is used to cushion during transportation, reducing bumps along the way. The gripping assembly 8 is used to stably clamp the materials. When adjusting the cab 4's height, the operation of the first hydraulic cylinder 32 drives the hydraulic rod 33 to move. The movement of the hydraulic rod 33 causes the slider 34 to slide on the base 31. The sliding of the base 31 causes the drive rod 35 to move within the drive groove 312, thereby moving the first connecting block 311. At this time, the first connecting block 311 drives the support plate 310 to move, and the lifting rod 39 moves within the limit frame 36, thus changing the height of the cab 4 and providing the cab 4 with a good view. The buffer mechanism 37 is used when the cab 4 lowers. The system provides cushioning to ensure a comfortable experience for the staff in the cab 4, reduces equipment wear, and triggers an alarm 38 when the cab 4 deviates, reminding staff to perform maintenance. When the main body 1 of the material handling machine travels on bumpy sections, the gripping component 8 shakes, causing the fixing block 74 to shake. The fixing block 74 then causes the first connecting rod 77 to shake within the rotating cylinder 76. At this time, the connecting ring 78 compresses the third spring 79, reducing the shaking of the gripping component 8 on bumpy sections. The operation of the motor 84 causes the grippers 88 to move closer together, facilitating material gripping. The rotating mechanism 86 is used to adjust the angle of the grippers 88, allowing for adjustments as needed to ensure close contact between the gripped materials. The clamping mechanism 87 limits the material on the grippers 88, making the material more stable during transport.
