Description

Technical Field

[0001] The utility model belongs to the technical field of new energy battery pack handling equipment, in particular to a new energy heavy truck battery pack side-changing forklift arm device. Background Art

[0002] The existing top-mounted battery packs on heavy trucks are huge (greater than 2 meters in height) and very heavy (2000-3500 kg). The lifting point is at the top, and it must be lifted and moved with the help of related mechanical equipment. Therefore, the existing heavy truck battery replacement needs to be carried out at a professional heavy truck battery replacement station. For many locations where professional battery replacement stations cannot be built, but there are trucks that need to be replaced, the battery replacement operation is relatively difficult. Although a forklift is a commonly used industrial handling vehicle, it is widely used in cargo loading and unloading, movement, and short-distance transportation operations, and has the possibility of being realized. However, the existing forklift arm is horizontally facing upward, that is, when lifting, the cargo is on the forklift arm. For cargo with a high lifting point and heavy weight, it is extremely unsafe to fork the cargo from the bottom, lift or lower the cargo vertically, and then move the vehicle for transportation. Therefore, how to develop a device that does not require professional lifting machinery to achieve safe lifting and moving of battery packs is one of the technical problems that need to be solved. Summary of the invention

It specifically includes a battery pack, a double fork arm, a hydraulic fine-tuning cylinder, a single fork arm adjustment cylinder, and a gripper; the double fork arm is two side-by-side L-shaped fork arm structures, one end of the fork arm structure is placed on the upper end surface of the battery pack, and the other end is movably mounted on the vertical door frame of the forklift; the hydraulic fine-tuning cylinder is connected to the double fork arm to adjust the vertical distance between the double fork arm and the battery pack; the single fork arm adjustment cylinder is provided with two groups, each group is independently connected to the fork arm of a double fork arm, and is used to adjust the relative distance between the forks in the horizontal direction; the gripper is an L-shaped structure, and is provided with a plurality of them, and the top end points are evenly fixedly installed on the double fork arm at intervals, for plugging the battery pack and the double fork arm.

[0004] As an improvement, the battery box also includes square tubes, which are installed in multiple pieces and are symmetrically installed on the top of the battery pack and perpendicular to the insertion direction of the double fork arms.

[0005] As an improvement, it also includes a camera device, which is fixedly installed on the top of the door frame in the vertical direction of the forklift.

[0006] As an improvement, six grippers are installed, two in a group, and symmetrically spaced on both sides along the square tube direction of the battery box.

[0007] As an improvement, six grippers are installed, with two in a group. Each group of grippers is in an L-shaped opening facing away from each other and is evenly distributed on the double fork arms.

[0008] Beneficial effects: The device proposed by the present utility model is convenient for processing, easy to operate, and can efficiently lift and move goods. It is convenient to use, has strong practicability, and high operation efficiency, effectively solving the problem that the existing battery pack requires a dedicated robot for lifting.

[0018] In the figure: battery pack 1, double fork arm 2, hydraulic fine-tuning oil cylinder 3, single fork arm adjustment oil cylinder 4, gripper 5, battery box square tube 6, gantry 7, camera device 8. Specific embodiments

[0019] The following combines embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0020] See Figure 1As shown, the new energy heavy truck battery pack side-changing forklift arm device includes a battery pack 1, a double fork arm 2, a hydraulic fine-tuning oil cylinder 3, a single fork arm adjustment oil cylinder 4, and a gripper 5. The double fork arm 2 is a structure of two L-shaped fork arms arranged side by side. One end of the fork arm structure is placed on the upper end face of the battery pack, and the other end is movably installed on the forklift vertical mast 7. The hydraulic fine-tuning oil cylinder 3 is connected to the double fork arm 2 and is used to adjust the vertical distance between the double fork arm 2 and the battery pack 1. There are two groups of single fork arm adjustment oil cylinders 4, and each group is independently connected to the fork arm of a double fork arm 2 and is used to adjust the relative distance between the fork arms in the horizontal direction. The gripper 5 is an L-shaped structure, and there are multiple grippers. The top endpoints are evenly and fixedly installed on the double fork arm 2 at intervals and are used to plug the battery pack 1 and the double fork arm 2.

[0021] It also includes a battery box square tube 6, and multiple battery box square tubes are installed symmetrically on the top of the battery pack 1 and are perpendicular to the insertion direction of the double fork arm 2.

[0022] It also includes a camera device 8, such as a camera, which is fixedly installed on the top of the forklift vertical mast 7. Six grippers 5 are installed, with two as a group. Each group of grippers 5 is arranged in a way that the L-shaped openings face away from each other and are evenly distributed on the double fork arm 2.

[0023] See Figures 1-9 As shown, invert the double fork arm. The double fork arm travels with the forklift to the side of the battery pack, and the double fork arm is above the battery box and higher than the top of the battery box.

[0024] Using the double fork arm hydraulic fine-tuning oil cylinder, through the high camera, the driver can adjust the position of the double fork arm and the battery box so that the center of the double fork arm is basically coincident with the center of the side of the battery pack. The double fork arm moves symmetrically towards the middle by the adjustment oil cylinders on their respective single fork arms, and the two arms contract the minimum distance to ensure that the battery box gripper can smoothly extend into the inner side of the battery box square tube at the top of the battery box. Subsequently, the double fork arm is lowered to the top of the battery box, and the adjustment oil cylinders on their respective single fork arms adjust the position of the double fork arm through the high camera, causing the single fork arms to move towards both sides, so that the battery pack grippers on the fork arms move below the battery box square tube. At this time, the forklift can slowly lift the battery box to complete the hoisting of the battery box.

[0025] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
