Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to a forklift with a rigid guiding mechanism. Background Technology

[0002] In industrial production, logistics warehousing, and port terminals, cargo handling and loading / unloading operations are key links in ensuring the efficient operation of the supply chain. Forklifts, as important equipment for lifting and transferring cargo, directly affect operational efficiency and safety.

[0003] Currently, traditional forklifts often have limitations in their structural design. Most forklifts lack a stable, rigid guiding mechanism between the frame and the fork assembly. During lifting operations, factors such as uneven cargo weight, fluctuating lifting speed, and external environmental interference (such as wind or uneven ground) can cause the fork assembly to sway laterally or longitudinally. This swaying can not only cause the cargo to shift or tilt during lifting, but may even lead to the risk of cargo falling, seriously threatening the safety of on-site personnel and the integrity of the equipment. Utility Model Content

[0004] To address the aforementioned issues, this utility model provides a rigid fork lifting device. By raising the frame and positioning frame, a rigid guiding mechanism is formed, which enhances the stability of the fork assembly during lifting, reduces swaying, and ensures the stability of cargo lifting and the safety of on-site operations.

[0005] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a rigid forklift, including a bridge and a fork assembly, a traveling trolley is provided on the bridge, a winch is provided on the upper part of the traveling trolley, a chain connected to the fork assembly is provided on the winch, a rigid guide mechanism located outside the chain is provided below the traveling trolley, the rigid guide mechanism includes a positioning frame, a lifting frame is slidably provided within the positioning frame, and a pulley group that cooperates with the chain is provided at the lower part of the lifting frame.

[0006] As a further improvement to the above technical solution:

[0007] The lower part of the positioning frame is provided with a guide frame, the guide frame is provided with a guide slider, and the four corners of the guide frame are provided with guide grooves.

[0008] The outer wall of the lifting frame is provided with a guide rail that mates with the guide groove, and the bottom of the lifting frame is provided with a base for mounting the fork assembly.

[0009] The fork assembly includes a connecting seat, a telescopic rod is provided inside the connecting seat, a mounting plate is provided at the movable end of the telescopic rod, and a fork body is provided on the side wall of the mounting plate.

[0010] A rotary disc is provided between the connecting seat and the base, and a drive source for driving the rotary disc is provided on the base.

[0011] A telescopic frame is provided between the positioning frame and the lifting frame, and a sprocket for use with the chain is provided on the inner side wall of the telescopic frame.

[0012] There are multiple telescopic frames, and each telescopic frame is provided with a guide joint at its bottom.

[0013] The beneficial effects of this utility model embodiment are as follows: The rigid fork lifting device includes a bridge frame and a fork assembly. A traveling trolley is provided on the bridge frame, and a winch is installed on the upper part of the traveling trolley. A chain connected to the fork assembly is provided on the winch, and a rigid guide mechanism located outside the chain is provided below the traveling trolley. The winch and chain serve as the power source for lifting and lowering the fork assembly. During the lifting and lowering process, the positioning frame and the lifting frame form a rigid guide mechanism, which can enhance the stability of lifting and lowering the fork assembly, reduce swaying, and ensure the stability of cargo lifting and the safety of on-site operations.

[0014] Using rigid guiding mechanisms instead of traditional cable and chain guiding methods can reduce equipment wear caused by shaking during use and extend the service life of the equipment. Attached Figure Description

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, the rigid forklift in this embodiment includes a bridge frame 1 and a fork assembly 2. A traveling trolley 3 is mounted on the bridge frame 1, and a winch 4 is mounted on the upper part of the traveling trolley 3. A chain 5 connected to the fork assembly 2 is mounted on the winch 4. The lifting and lowering operation of the fork assembly 2 is driven by the winch 4 and the chain 5. A rigid guide mechanism located outside the chain 5 is provided below the traveling trolley 3. The rigid guide mechanism includes a positioning frame 6 connected to the traveling trolley 3. A lifting frame 7 connected to the fork assembly 2 is slidably mounted inside the positioning frame 6. A pulley block 8 that works with the chain 5 is provided at the lower part of the lifting frame 7. The winch 4 and the chain 5 serve as the power source for lifting and lowering the fork assembly 2. During the lifting and lowering process, the positioning frame 6 and the lifting frame 7 provide guidance, which can enhance the stability of the lifting and lowering of the fork assembly, reduce swaying, and ensure the stability of the cargo lifting and the safety of on-site operations.

[0023] The lower part of the positioning frame 6 is provided with a guide frame 9, and the guide frame 9 is provided with a guide slider 10. There are multiple guide blocks 10. The guide frame 9 adopts a rectangular frame, and there are eight guide blocks 10. Two are installed on each side wall and are symmetrically installed on two opposite side walls. The guide blocks 10 are used to fill the gap between the positioning frame 6 and the lifting frame 7, further reducing the shaking of the fork assembly 2 during the lifting process. The four corners of the guide frame 9 are provided with guide grooves 11.

[0024] The outer wall of the lifting frame 7 is provided with a guide rail 12 that works with the guide groove 11. The bottom of the lifting frame 7 is provided with a base 13 for installing the fork assembly 2. The guide groove 11 and the large cabinet 12 can further improve the lifting stability of the fork assembly 2. Together with the guide block 10, it provides multi-level protection for the lifting of goods.

[0025] The fork assembly 2 includes a connecting seat 14, and a telescopic rod 15 is provided inside the connecting seat 14. The telescopic rod 15 is a hydraulic push rod and there are two of them. They are symmetrically distributed about the center line of the mounting plate 16. The movable end of the telescopic rod 15 is provided with the mounting plate 16. The side wall of the mounting plate 16 is provided with two fork bodies 17, and both of them are L-shaped.

[0026] A rotary disk 18 is provided between the connecting seat 14 and the base 13. The base 13 is provided with a drive source 19 for driving the rotary disk 18. The drive source 19 includes a motor and a reducer. A drive gear is installed at the output end of the reducer. A driven gear is provided on the outside of the rotary disk 18. The rotary disk 18 is driven to rotate by the drive source 19, thereby adjusting the direction of the fork assembly 2 and completing the transfer operation of goods.

[0027] A telescopic frame 20 is provided between the positioning frame 6 and the lifting frame 7. A sprocket 21 is provided on the inner side wall of the telescopic frame 20 to cooperate with the chain 5. After the sprocket 21 cooperates with the chain 5, it can drive the telescopic frame 20 to move synchronously longitudinally with the lifting operation of the lifting frame 7.

[0028] The telescopic frame 20 serves as a supplement to the lifting height of the lifting frame 7. There are multiple telescopic frames 20 with a sliding design between adjacent ones. When the fork assembly 2 is lifted, the telescopic frame forms a multi-section telescopic mechanism, which can guide the operation and increase the lifting distance. Each telescopic frame 20 is provided with a guide section 22 below it. The guide section 22 has the same function and structure as the guide frame 9.
