Description

Technical Field

[0001] This utility model relates to the field of lifting forklift technology, and in particular to a lifting lug for a lifting forklift and a lifting device for a lifting forklift. Background Technology

[0002] In port ship loading and unloading operations, loaders such as forklifts and bulldozers are among the main equipment used. However, their operating range is limited, requiring them to be lowered into the ship's hold by gantry cranes for auxiliary operations. Loaders can be lowered into the ship's hold or storage yard to work in conjunction with gantry cranes, transferring goods from under the gantry crane to a designated location, or moving goods from a designated location to under the gantry crane for loading or unloading operations.

[0003] To facilitate forklift lifting, patent CN115285824A discloses a lifting device for port forklifts, relating to the field of port forklift lifting technology. It includes a lifting chain assembly, a main frame, and a wire rope assembly. The lifting chain assembly is connected to the main frame; the wire rope assembly is also connected to the main frame; the lifting chain assembly, main frame, and wire rope assembly are sequentially arranged and connected. Four lifting chains are provided, each with a buckle at one end. Two lifting chains located on one side of the main frame are connected by buckles. Four wire ropes are located on the bottom side of the main frame, fixed to the four corners of the bottom side of the main frame by wire rope fixing seats and wire rope bolts. Depending on the different lifting points at the front and rear of the forklift, the two wire ropes at the front end of the main frame are shorter than the two wire ropes at the rear end of the main frame.

[0004] In the above solution, the two steel cables at the rear end of the main frame are quite long, which makes the forklift prone to significant swaying during lifting under the influence of external impacts or wind, affecting the efficiency of landing; and existing forklifts, such as Figure 1 and Figure 2 As shown, the forklift has a lifting buckle on the rear thread, which is easy to connect to the wire rope; however, the fixed plate 10 at the upper end of the forklift's front frame 12 has a through hole 11, which is vertically oriented and located at the connection between the front frame 12 and the fixed plate 10. Currently, in most operations, the wire rope is bypassed through the through hole 11, and the end of the wire rope is fixed with a U-bolt, which makes the lifting operation cumbersome and affects efficiency. Utility Model Content

[0005] To address the problem of cumbersome and inefficient operation of connecting and fixing the forklift front frame to the wire rope, this utility model provides a lifting lug for lifting forklifts.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A lifting lug for a forklift includes a limiting plate. A cylinder is fixedly mounted on the center of the top surface of the limiting plate. A lifting hole is provided at the end of the cylinder away from the limiting plate. A notch is provided on one side of the limiting plate. The notch facilitates the connection between the lifting lug and the forklift front frame, increases the contact area between the limiting plate and the forklift front frame, and improves efficiency.

[0008] Preferably, the edge of the notch is tangent to the outer wall of the cylinder.

[0009] On the other hand, this utility model also provides a lifting device for forklifts, including the aforementioned lifting lugs and a rectangular frame; hooks are connected to the bottom corners of the frame via wire ropes; lifting rings are connected to the top corners of the frame via lifting chains; the hook at the front end of the frame is connected to a lifting hole; and the hook at the rear end of the frame is connected to a lifting buckle. This facilitates the connection of the lifting lugs and lifting buckles using the hooks, making it easier to connect the lifting device to the forklift and ensuring work efficiency.

[0010] Preferably, the frame is telescopically adjustable along its length; the frame includes a middle frame; a front frame is slidably mounted on the front end of the middle frame; a rear frame is slidably mounted on the rear end of the middle frame; the front frame and the middle frame, as well as the rear frame and the middle frame, are fixed together by pins. This telescopic design allows for easy adjustment of the frame length according to different forklift models, improving stability during lifting.

[0011] Preferably, the front frame includes two side bars; two connecting rods are arranged between the two side bars; the side bars are inserted into the middle frame; the side bars and the middle frame are fixed together by pins; the rear frame includes two L-shaped bars; four connecting rods are fixed between the two L-shaped bars; one end of the L-shaped bar is inserted into the middle frame; the L-shaped bar and the middle frame are fixed together by pins. The L-shaped bar design reduces the length of the wire rope connection to the rear end of the forklift, improves the rigidity of the connection, reduces swaying, and ensures efficiency when the forklift is lowered to the ground. Furthermore, the telescopic design of the frame facilitates the connection between the L-shaped bar and the lifting hook.

[0012] Preferably, the middle frame includes a U-shaped frame; a connecting plate is provided in the middle of the U-shaped frame; rubber pads are provided on both the front and rear sides of the bottom of the connecting plate; the side bars and L-shaped bars are inserted into the U-shaped frame. The rubber pads reduce friction between the frame and the top surface of the forklift, making it easier to reduce the distance between the frame and the forklift, ensuring stability during lifting, and reducing swaying.

[0013] As can be seen from the above technical solutions, the advantages of this utility model are:

[0014] 1. This solution provides a lifting lug for a forklift. The notch design facilitates the connection between the lifting lug and the forklift front frame, increases the contact area between the limit plate and the forklift front frame, and improves efficiency.

[0015] 2. This utility model also provides a lifting device for lifting forklifts. By setting an L-shaped bar, the length of the wire rope connected to the rear end of the forklift is reduced, the rigidity of the connection is improved, the swaying is reduced, and the efficiency of lifting the forklift when it is landed is ensured.
