Description

Technical Field

[0001] The present application relates to the technical field of handling equipment, and in particular to an oil-electric hybrid dual-power grabber. Background Art

[0002] With the rapid development of industrial technology, material grabbers, as important material handling equipment, play an irreplaceable role in various industrial production. Most traditional material grabbers use a single fuel or electricity as a power source, which to a certain extent limits their application scope and efficiency. With the increasing awareness of environmental protection and the optimization and adjustment of energy structure, oil-electric hybrid dual-powered material grabbers have emerged, and the demand for the functions of material grabbers has also increased.

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

[0004] 1. The existing grabbers do not fully consider the stability and reliability of the equipment during the design and manufacturing process. When grabbing materials, the clamping claws cannot rotate according to the needs, and the materials can only be moved by simply moving the clamping arms close. In this way, when grabbing the stacked materials, there are large gaps in the middle of the grabbed materials, which are easy to loosen in the clamping claws, resulting in unstable grabbing, which may cause the materials to fall, etc., increasing the safety hazards of personnel and equipment.

[0005] 2. In the design of traditional grabbers, the position of the cab is mostly fixed and lacks the corresponding lifting structure, which limits the driver's field of vision to a certain extent, resulting in inaccurate handling position, which in turn affects the accuracy and safety of the operation. In addition, the grabber with a cab lifting structure does not have a buffering effect when lifting, and brings a strong sense of vibration when falling, causing great wear and tear on the equipment. At the same time, it is difficult to detect the deviation of the cab in time, so it is impossible to perform maintenance in time.

[0006] 3. The existing gripper will inevitably encounter bumpy roads during the material transfer process, which will cause the jaws to shake to a certain extent, so that the material on the jaws shakes, causing wear on the jaws and the material, reducing the service life of the jaws. At the same time, it is difficult to adjust the angle of the gripping component. Summary of the invention

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

[0019] 1. The use of a grabbing assembly effectively solves the problem that the stability and reliability of the equipment are not fully considered during the design and manufacturing process of the existing grabbing machine. When grabbing materials, the clamping claws cannot be rotated according to the needs, and the clamping arms can only be moved closer to transport the materials. In this way, when the stacked materials are grabbed, there is a large gap in the middle of the grabbed materials, which is easy to loosen in the clamping claws, resulting in unstable grabbing, which may cause the materials to fall, etc., increasing the safety hazards of personnel and equipment. The present invention enables the clamping claws of the grabbing assembly to rotate according to the specifications of the materials, so that the materials are closer together, and at the same time, the upper part of the materials is limited, and the limiting mechanism can be adaptively adjusted according to the specifications of the materials, thereby improving the stability of the materials in the clamping claws and preventing the materials from falling during transportation.

[0020] 2. The use of the lifting component effectively solves the problem that in traditional grabber designs, the position of the cab is mostly fixed and there is a lack of corresponding lifting structure, which limits the driver's field of vision to a certain extent, resulting in inaccurate handling position, which in turn affects the accuracy and safety of operation. In addition, the grabber with a cab lifting structure has no buffering effect when lifting, and it brings a strong sense of vibration when falling, which causes great wear and tear on the equipment. At the same time, it is difficult to detect the displacement of the cab in time, so that maintenance cannot be carried out in time. The present invention can change the height of the cab according to needs through the lifting component, providing the driver with a good field of vision. At the same time, it has a buffering mechanism when falling, which reduces equipment wear and tear, improves the driving experience of the staff, and can detect the displacement of the cab in time, which is convenient for subsequent maintenance.

[0021] 3. The use of the buffer component effectively solves the problem that the existing grabbers will inevitably encounter bumpy sections during the material transfer process, which causes the jaws to shake to a certain extent, thereby causing the material on the jaws to shake, causing wear on the jaws and the material, reducing the service life of the jaws, and making it difficult to adjust the angle of the grabbing component. The present invention can reduce the shaking of the jaws on bumpy sections through the buffer component, reduce the shaking caused by rapid starting and emergency stopping of materials during transfer, improve the stability of material transfer, reduce equipment wear, and increase the service life of the equipment. At the same time, the angle of the grabbing component can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] There are large gaps in the middle of the materials after being grasped, which are easy to loosen in the clamp. The clamp of the grasping assembly of the present invention can be rotated according to the specifications of the materials to make the materials tighter. The position of the cab is mostly fixed and lacks a corresponding lifting structure, which limits the driver's field of vision to a certain extent. The present invention can change the height of the cab according to needs through the lifting assembly to provide the driver with a good field of vision. The clamp causes shaking of the jaws due to bumpy roads. The present invention can reduce the shaking of the clamp on bumpy roads through the buffer assembly.

[0037] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Example

[0039] See also Figure 1As shown, a hybrid oil-electric dual-power grabber includes a grabber body 1. A power mechanism 2 is arranged on the upper surface of the grabber body 1. The power mechanism 2 has two modes, diesel power and electric power. Under normal circumstances, they work independently, but can also be switched or used in combination as needed. Diesel power mode: when there is no external power supply to connect to the site and the electric motor cannot continue to work, the diesel engine will be used as the main power source. The operator can quickly switch to the diesel engine drive to ensure that the grabber can continue to operate. Electric power mode: When there is a stable external power supply at the work site, in order to minimize the operating costs and environmental impact, the grabber operator can switch to an external power supply to drive the motor to drive the whole machine. When working in areas with strict requirements on environmental protection and noise, in order to comply with relevant regulations or reduce the impact on the surrounding environment, it plays a positive role. A lifting component 3 is provided on the upper surface of the grabber body 1, and a cab 4 is fixedly installed on the upper surface of the lifting component 3. A mechanical arm 5 is provided on the upper surface of the grabber body 1, and a second hydraulic cylinder 6 is provided on the outer surface of the mechanical arm 5. A buffer component 7 is provided at the end of the mechanical arm 5 away from the grabber body 1, and a grabbing component 8 is provided at the bottom end of the buffer component 7. The lifting component 3 is used for lifting to change the height of the cab 4, thereby providing the cab 4 with a good field of vision. The work of the second hydraulic cylinder 6 drives the mechanical arm 5 to rotate, which is convenient for transferring materials on the grabbing component 8. The buffer component 7 is used for buffering during transportation to reduce bumps on the road. The grabbing component 8 is used to stably clamp the material.

When the cab 4 is raised and lowered, the operation of the first hydraulic cylinder 32 drives the hydraulic rod 33 to move, and 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 driving rod 35 to move in the inner cavity of the driving 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, so that the cab 4 has a good field of view, and the buffer mechanism 37 is used for buffering when the cab 4 is lowered, so that the staff in the cab 4 can have a good experience and reduce the wear of the equipment. At the same time, the alarm mechanism 38 can sound an alarm when the cab 4 is offset, reminding the staff to perform maintenance.

[0041] See also Figure 2 and Figure 4As shown, the buffer mechanism 37 includes a buffer frame 371, a fixed rod 372 is fixedly installed on the inner wall of the buffer frame 371, a first spring 373 is sleeved on the middle part of the fixed rod 372, a sliding sleeve 374 is slidably connected to the outer surface of the fixed rod 372, the sliding sleeve 374 is located at both ends of the first spring 373, a connecting strip 375 is rotatably connected to the upper surface of the sliding sleeve 374, and a buffer plate 376 is rotatably connected to the upper surface of the connecting strip 375.

Pressing the button 386 drives the alarm 385 to sound an alarm. The outer surface of the distance adjusting block 384 near the button 386 is The surface is inclined and the bottom is narrow, so that when the distance adjusting block 384 is lowered, the displacement of the cab 4 can drive the distance adjusting block 384 to squeeze the button 386. The connecting plate 381 is fixedly connected to the support plate 310, and when the cab 4 is lowered, the support plate 310 is driven to descend. At this time, the connecting plate 381 approaches the buffer plate 376, so that the buffer plate 376 is squeezed. The squeezing of the buffer plate 376 drives the connecting strip 375 to rotate. The rotation of the connecting strip 375 drives the sliding sleeve 374 to move on the fixing rod 372. The movement of the sliding sleeve 374 drives the first spring 37 The first spring 373 is squeezed by the sliding sleeve 374, and the elastic force of the first spring 373 reduces the shaking of the cab 4 when it descends, so that the wear of the equipment is reduced and the service life of the equipment is increased. When the cab 4 deviates, the distance adjusting block 384 contacts the button 386, so that the button 386 is pressed to trigger the alarm 385 to sound an alarm, reminding the staff to perform maintenance. The first threaded rod 382 is used to adjust the position of the distance adjusting block 384 on the connecting plate 381, so as to facilitate the adjustment of the position of the distance adjusting block 384, so that the distance adjusting block 384 and the button 386 do not contact when the cab 4 is not deviated.

The top of the rotating cylinder 76 is rotatably connected to the mechanical arm 5. When the grabber body 1 runs to a bumpy section, the grabbing assembly 8 shakes, and the shaking of the grabbing assembly 8 drives the fixing block 74 to shake. The fixing block 74 drives the first connecting rod 77 to shake in the inner cavity of the rotating cylinder 76. At this time, the connecting ring 78 squeezes the third spring 79. The elastic force of the third spring 79 reduces the shaking of the grabbing assembly 8 on the bumpy section, and when the grabbing assembly 8 is in the direction of the mechanical arm 5, the elastic force of the second spring 73 keeps the buffer block 71 between the fixing blocks 74, reducing the impact of the mechanical arm 5 on the grabbing assembly 8 caused by emergency stops during transportation.

The inner cavity of the third cylinder 872 is slidably connected to a third piston rod 873. The third piston rod 873 and the pressure plate 871 are fixedly connected. The bottom end of the pressure plate 871 is provided with a distance adjustment groove 874. The inner cavity of the pressure plate 871 is rotatably connected to a third threaded rod 875.

The outer surface of the third threaded rod 875 is provided with a protrusion, and the outer surface of the belt 876 is provided with a groove. The protrusion and the groove are engaged, so that it is convenient to rotate one third threaded rod 875 to drive the other two third threaded rods 875 to rotate.

The inner cavity of the limit plate 8776 is provided with a fifth spring. The elastic rod 8777 and the fifth spring are elastically connected. After the clamping claw 88 clamps the material, the work of the third cylinder 872 drives the third piston rod 873 to move, and the movement of the third piston rod 873 drives the pressure plate 871 to move toward the material. At this time, the bottom end of the limiting mechanism 877 fits the material to limit the material and prevent the material from loosening. At the same time, the spacing of the limiting mechanism 877 can be adjusted in advance according to the amount of material clamped each time. The third threaded rod 875 is rotated to drive the belt 876 to rotate, so that the limiting mechanism 877 on the distance adjusting slot 874 moves, thereby limiting the material. Mechanism 877 can be deformed according to the shape of the material.

[0046] In summary, the lifting assembly 3 is used for lifting to change the height of the cab 4, thereby providing the cab 4 with a good field of vision.

The buffer assembly 7 is used for buffering during transportation to reduce bumps on the road. The grabbing assembly 8 is used for stably clamping the materials. When the cab 4 is lifted and lowered, 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 driving rod 35 to move in the inner cavity of the driving 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, so that the cab 4 has a good field of vision, and the buffer mechanism 37 is used when the cab 4 is lowered.

At the same time, the alarm mechanism 38 can sound an alarm when the cab 4 deviates, reminding the staff to perform maintenance. When the grabber body 1 runs to a bumpy section, the grabbing assembly 8 shakes, and the shaking of the grabbing assembly 8 drives the fixing block 74 to shake, and the fixing block 74 drives the first connecting rod 77 to shake in the inner cavity of the rotating cylinder 76. At this time, the connecting ring 78 squeezes the third spring 79, and the elastic force of the third spring 79 reduces the shaking of the grabbing assembly 8 on the bumpy section. The work of the motor 84 drives the clamping jaws 88 to move closer to each other, which is convenient for grabbing materials. The rotating mechanism 86 is used to adjust the angle of the clamping jaw 88, which is convenient for adjusting the angle of the clamping jaw 88 according to needs, so that the grabbed materials are in close contact with each other, and the clamping mechanism 87 is used to limit the material on the clamping jaw 88, so that the material is more stable during transportation.
