Description

Technical Field

[0001] The present application relates to the technical field of brick moving equipment, and in particular to a pure electric powered grabber. Background Art

[0002] A material grabber is a machine for material transfer, which is generally evolved from a hydraulic excavator. The biggest difference between a material grabber and an ordinary excavator is the difference in the front-end working device, that is, the different working purposes: the large and small arms of an ordinary excavator are generally shorter, with a bucket at the front end, and its main function is to carry out excavation and loading operations; the large and small arms of a material grabber, commonly known as a "material grabber arm", are generally longer, and the shape and structure are also different from those of an ordinary excavator. Its front end is a wood grabber, and its main function is to load, unload and carry wood, timber, reeds, straw and various strip materials. It often uses a pure electric power system, and has broad development prospects in the field of engineering machinery with its advantages of zero emissions, high efficiency and energy saving, convenient operation and easy maintenance.

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

[0004] 1. The existing gripper has too strong rigidity, which can easily damage the material when clamping it, and insufficient clamping force can easily cause the material to fall off. In addition, most materials are irregular in shape. For example, the most transported wood, each piece of wood is usually of different thicknesses, and the thickness of one end and the other end of the same wood is also different. The parallel movement of the gripper will produce uneven force, resulting in unstable material gripping and the risk of falling off.

[0005] 2. The height of the existing grabber cab is mostly fixed, 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. Some grabbers with a cab lifting structure do not have a buffering effect when lifting, and bring a strong sense of vibration when falling, causing great wear and tear on the equipment. At the same time, it is not convenient for short drivers to enter the cab.

[0006] 3. The inertia caused by the start and stop of the existing grabber during the material transfer process will cause the material to deviate greatly. In severe cases, the material will fall off the gripper, seriously affecting the life safety of the construction workers on site. Summary of the invention

[0019] 1. The use of a material grabbing assembly solves the problem that the existing material grabber's jaws are too rigid, which easily damages the materials when clamping them, and insufficient clamping force easily causes the materials to fall off. In addition, most materials are irregular in shape. Taking the most transported wood as an example, each wood is usually of different thicknesses, and the thicknesses of one end and the other end of the same wood are also different, which causes uneven force when the jaws move in parallel, resulting in unstable material gripping and the risk of falling off. The present invention has a flexible clamping effect through the material grabbing assembly, which can fix the materials well and prevent the materials from being damaged due to excessive clamping force. At the same time, the jaws can be adjusted, with an adaptive clamping effect, so that the irregular materials are subjected to more uniform force, thereby making the materials more stable during transportation.

[0020] 2. The use of a lifting assembly solves the problem that the height of the cab of existing grabbers is mostly fixed, which limits the driver's field of vision to a certain extent, resulting in inaccurate handling position, and further affecting the accuracy and safety of the operation. Some grabbers with a cab lifting structure do not have a buffering effect when lifting, and bring a strong vibration feeling when falling, causing great wear and tear on the equipment. At the same time, it is not convenient for drivers with short stature to enter the cab. The present invention can adjust the height of the cab according to needs through the lifting assembly, so as to provide a good field of vision. It has a buffering structure when retracted, which reduces the wear and tear of the equipment and provides a good driving experience, and at the same time facilitates short drivers to enter the cab.

[0021] 3. The use of the correction component solves the problem that the inertia caused by the start and stop of the existing grabber during the material transfer process will cause the material to deviate greatly, and in severe cases, cause the material to fall off the clamp, seriously affecting the life safety of the site construction personnel. The present invention reduces the influence of the inertial force when the grabber component is started or stopped urgently, prevents the material from falling off, and ensures the life safety of the site construction personnel.

[0039] The rigidity of the gripper's jaws is too strong, which may easily damage the materials when clamping them, while insufficient clamping force may easily cause the materials to fall off. The present invention has a flexible clamping effect through the gripping component, which can fix the materials well and prevent the materials from being damaged due to excessive clamping force; the height of the cab is mostly fixed and the field of vision is limited. The present invention can adjust the height of the cab according to needs through the lifting component, so as to provide a good field of vision; the inertia caused by the starting and stopping of the gripper during the material transport process may cause a large deviation of the materials. The present invention reduces the influence of the inertia force through the correction component when the gripping component is started or stopped urgently, so as to prevent the materials from falling off.

The first piston rod 38 is meshed, and a lifting frame 311 is fixedly installed on the top end of the first piston rod 38. The gear rod 310 and the lifting frame 311 are fixedly connected. The operation of the first cylinder 37 drives the first piston rod 38 to move upward. At this time, the first piston rod 38 drives the lifting frame 311 to move. The movement of the lifting frame 311 drives the gear rod 310 to move. The movement of the gear rod 310 drives the gear 35 to rotate. The rotation of the gear 35 drives the first rotating rod 34 to rotate in the inner cavity of the support block 32, keeping the two gear rods 310 moving synchronously in the inner cavity of the limit cylinder 39. Compared with the use of two first cylinders 37 to achieve upgraded synchronization, the lifting frame 311 is more evenly stressed.

At this time, the buffer block 338 moves toward the inner cavity of the buffer seat 334, driving the connecting bar 337 to rotate. The rotation of the connecting bar 337 drives the slider 335 to move to both sides in the inner cavity of the buffer seat 334, so that the slider 335 squeezes the first spring 336. The elastic force of the first spring 336 has a certain buffering effect, reducing the wear of the equipment. At the same time, the first threaded rod 332 is rotated to drive the buffer seat 33 The inner cavity of the adjusting groove 333 moves, so that the position of the buffer seat 334 on the buffer frame 331 changes, so that the contact position of the lifting frame 311 and the buffer plate 339 changes, so as to prevent the lifting frame 311 from colliding at the same position every time, and reduce the probability of deformation of the lifting frame 311, so as to achieve the effect of protecting the equipment. In addition, the handle 362 can be pulled to make the step frame 361 move outward on the slide groove 363, and the driver can enter the cab 4 by stepping on the step frame 361, which is convenient for people with short stature to use.

In case of sudden stopping and braking, the grabbing assembly 7 moves to drive the first connecting block 66 to move, and the movement of the first connecting block 66 drives the correction block 63 to move. The movement of the correction block 63 drives the first connecting rod 64 to move in the inner cavity of the fixed block 62.

When the plug rod 794 is in the appropriate position, the plug rod 794 is released, and the elastic force of the fifth spring 796 drives the fixing ring 795 to move downward, so that the plug rod 794 is engaged with the socket 793 again, so that the distance adjusting rod 792 is fixed in the fixed position of the inner cavity of the rotating frame 78, so that the floating plate 798 can be close to the material, ensuring that the floating plate 798 can clamp the material when the rotating frame 78 moves. When grabbing wood, the thickness of the two ends of the wood is uneven. At this time, the floating plate 798 can be connected The plate 791 rotates, that is, the floating ball 797 rotates in the inner cavity of the floating plate 798, so that the sixth spring 7910 receives different pressures, so that the positions of the second connecting rod 799 at both ends of the connecting plate 791 are different, that is, the floating plate 798 is tilted relative to the connecting plate 791, so that the floating plate 798 as a whole can better contact the wood, and the wood can be more evenly stressed within the clamping range of the floating plate 798. The second connecting rod 799 can move on the connecting plate 791, so that the sixth spring 7910 can provide a certain flexible force to prevent the material from being damaged due to excessive clamping force.

[0048] In summary, the lifting component 3 is used to drive the cab 4 to rise and fall, the correction component 6 is used to prevent sudden stops and rapid rotations to prevent the material from shaking greatly, the grabbing component 7 is used to flexibly clamp the material, and the operation of the first cylinder 37 drives the first rotating rod 34 to rotate in the inner cavity of the support block 32, keeping the two gear rods 310 moving synchronously in the inner cavity of the limit cylinder 39. Relatively speaking, the use of two first cylinders 37 to achieve a better upgrade synchronization effect makes the lifting frame 311 evenly stressed, and the buffer adjustment mechanism 33 is used to reduce equipment wear. When the grabbing component 7 transports materials, sudden stops and sudden brakes will occur. A certain buffer is achieved between the mechanical arm 5 and the grabbing component 7 through the correction component 6. When the grabbing component 7 stops and suddenly brakes, it moves and drives the first connecting rod 64 to the fixed block 62 The inner cavity moves, and the elastic force of the second spring 65 keeps the correction block 63 in its original position, thereby reducing the inertia force generated by the grab assembly 7 during emergency stops and sudden braking. In bumpy sections, the first connecting block 66 moves in the inner cavity of the correction block 63, squeezing the third spring 67. At this time, the elastic force of the third spring 67 plays a buffering effect when the equipment moves on bumpy sections, preventing the material from falling off the grab assembly 7. When grabbing the material, the work of the third cylinder 74 drives the rotating frame 78 to approach each other, so that the grab rod 711 holds the material, so that the material is stored in the inner cavity of the grab rod 711 at both ends. The limiting mechanism 72 is used to limit the material from the upper end, and the clamping mechanism 79 is used to flexibly fix the material from both sides, thereby improving the stability of the material on the grab assembly 7.
