Description

Technical Field

[0001] This utility model relates to the field of transfer tooling technology, specifically a forklift trolley for picking up PAN raw yarn rolls after they have been laid to the ground. Background Technology

[0002] PAN precursor fibers are formed from PAN solution through spinning. PAN solution is currently the raw material for preparing high-performance PAN-based carbon fiber precursor fibers. The PAN precursor fiber solution is obtained through homogeneous solution polymerization or heterogeneous precipitation polymerization. After preparation, the PAN precursor fibers are wound onto a cylindrical tooling using a winding device to collect them and form PAN precursor fiber rolls. These rolls can be transferred and stored using various tooling. However, during the transfer process, limitations of storage locations, tooling, and the transport environment inevitably cause some rolls to fall to the ground. Due to their weight, these rolls cannot be moved manually; mechanical force is required. Typically, the fallen rolls are manually transferred from the ground to the center of the two forks of a stacker truck, and then the forks are lifted for transport. This process causes secondary damage to the quality of the PAN precursor fibers, resulting in an increase in fuzz on the outer layer of the roll. To address this issue, we have proposed a PAN raw yarn forklift trolley that can directly pick up raw yarn rolls that have been dropped, thus avoiding secondary damage to the raw yarn rolls, especially large-diameter raw yarn rolls, during the handling process. Utility Model Content

[0003] The purpose of this invention is to provide a PAN raw yarn forklift trolley to solve the problem mentioned in the background art, where the surface of the PAN raw yarn roll is scratched during the secondary handling process after the roll is placed on the ground, resulting in increased fuzz and reduced quality.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A forklift trolley for handling PAN raw yarn rolls after they are laid to the ground includes a frame, a sliding compartment, a carrying platform, and a lifting mechanism. The frame has directional wheels at the front of the bottom crossbeam and omnidirectional wheels at the rear, allowing the trolley to move and rotate. A top connecting plate and a frame pin are welded to the top of the frame's pulley grooves, and a frame connecting plate is also welded to the lower middle section for positioning and fixing the frame. The bottom crossbeam is connected to a hydraulic mechanism via a hydraulic cylinder base connecting plate to provide lifting power. The bottom of the hydraulic mechanism is connected to a hydraulic cylinder base connecting plate, and reinforcing ribs are welded between the hydraulic cylinder base connecting plate and the bottom crossbeam to secure the hydraulic cylinder base connecting plate and the hydraulic mechanism. A hydraulic cylinder connecting block is connected to the top of the hydraulic mechanism, and the hydraulic cylinder connecting block is assembled with a sprocket shaft and sprockets. There are two hydraulic cylinder connecting blocks, symmetrically distributed along the center of the hydraulic cylinder. The top of the connecting blocks is connected to a sprocket shaft through mounting holes. Sprockets are connected to both ends of the sprocket shaft, symmetrically distributed along the center of the hydraulic cylinder. The sprockets rotate with the sprocket shaft through keyways and keys for fixation. The sprocket is equipped with a rolling chain, and the two ends of the rolling chain are connected to the frame connecting plate and the sliding chamber respectively through chain connecting blocks. The sliding chamber is made of a bent plate, shaped like a C. A first material plate fixing rod and a second material plate fixing rod are connected to the two wings of the bent plate, respectively. A coiled material plate is connected between the sliding chamber and the first and second material plate fixing rods. A sliding chamber connecting plate is located on the back of the sliding chamber, used to connect the sliding chamber and the chain connecting block to realize the lifting function of the sliding chamber. The sliding chamber and the frame have pulley grooves, and a pulley assembly is located on the back of the trolley's sliding chamber. The pulley assembly cooperates with the frame pulley grooves; when the sliding chamber is raised or lowered, the cooperation of the pulley assembly reduces friction during sliding and also positions the sliding chamber to achieve vertical lifting. The wire roll carrier plate is connected to the first and second carrier plate fixing rods via a sleeve. The wire roll carrier plate is also kept vertically fixed by the first and second carrier plate fixing rods. The wire roll carrier plate and the sliding chamber are kept horizontally fixed by the first and second positioning sleeves on the first and second carrier plate fixing rods. The wire roll carrier plate is L-shaped overall, with a reinforcing rib around its edge to enhance its strength. The sleeve connection connects the wire roll carrier plate to the sliding chamber, which can be raised and lowered via a hydraulic cylinder mechanism.

[0006] By combining the above equipment components and methods, the PAN raw yarn rolls can be forked after landing, and then the PAN raw yarn rolls can be transferred, thus solving the problem of the raw yarn being damaged again during the subsequent transportation process after the PAN raw yarn rolls have landed.

[0010] The hydraulic cylinder connecting block consists of two pieces, symmetrically distributed along the center of the hydraulic cylinder. A sprocket shaft is connected to the top of the connecting block through a mounting hole. Sprockets are connected to both ends of the sprocket shaft, and the sprockets are symmetrically distributed along the center of the hydraulic cylinder. The sprockets rotate with the sprocket shaft due to the fixing effect of keyways and keys.

The sliding compartment and the frame have pulley grooves, and a pulley assembly is located on the back of the sliding compartment. The pulley assembly works in conjunction with the frame pulley grooves. When the sliding compartment is raised or lowered, the pulley assembly reduces friction during sliding and also positions the sliding compartment to achieve vertical lifting.

[0013] The wire roll carrier plate is connected by a first carrier plate fixing rod and a second carrier plate fixing rod. The wire roll carrier plate is also kept vertical by the first carrier plate fixing rod and the second carrier plate fixing rod.

The assembly connects the yarn roll carrier plate in the middle, and the sliding compartment can be raised and lowered via a hydraulic cylinder mechanism. This ensures smooth operation of the forklift trolley and enables the PAN raw yarn to be picked up from the ground. Attached Figure Description
