Forklifts, as an important handling tool, play a crucial role in this process. Forklifts are handling vehicles used for loading, unloading, and short-distance transportation of goods, providing convenience and efficiency for warehousing and logistics operations. Currently, most forklift loading and unloading operations rely on forward, backward, and steering control, typically requiring ample space for vehicle movement. Furthermore, precision control is difficult, and work efficiency needs improvement.

[0003] Based on the above problems, there is an urgent need to provide a forklift handling structure and a three-way forklift to improve the work efficiency of forklift handling. Utility Model Content

[0004] The purpose of this invention is to solve all or part of the aforementioned problems by providing a forklift handling structure and a three-way forklift. A fork assembly is mounted on the cantilever, and the fork assembly includes a scissor lift assembly capable of moving the fork assembly. Simultaneously, a rotary drive device drives the scissor lift assembly to rotate, causing the fork assembly to rotate 180°. The rotary drive device and hydraulic cylinders are controlled by a control valve group, eliminating the need for vehicle body movement and enabling precise control even in confined spaces. This improves the operational flexibility and work efficiency of the equipment while enhancing safety.

[0005] This utility model provides a forklift handling structure and a three-way forklift, including a cantilever and a fork assembly, the fork assembly being mounted on the cantilever. The fork assembly includes a scissor lift assembly, a fork assembly, and a rotary drive device. The scissor lift assembly is mounted on the rotating end of the rotary drive device, and the fork assembly is mounted on one end of the scissor lift assembly. The rotary drive device drives the scissor lift assembly to rotate, enabling multi-angle operation. Simultaneously, the extension and retraction of the scissor lift assembly drives the fork assembly to move back and forth, improving the operational flexibility and work efficiency of the equipment, and enhancing safety.

[0006] The cantilever frame has a first mounting hole on its upper part. The cantilever frame includes a bottom support platform, and a second mounting hole is provided on the bottom support platform. The rotary drive device is fixedly installed in the first mounting hole, and the scissor lift assembly is rotatably installed on the bottom support platform through the second mounting hole. The rotary drive device drives the scissor lift assembly to rotate 180°, enabling precise positioning of the target location and flexible angle adjustment according to handling requirements.

[0007] The first mounting hole and the second mounting hole are coaxially arranged to ensure that the rotary drive mechanism can drive the scissor assembly to rotate, thereby reducing equipment wear.

[0008] The rotary drive device is equipped with a mounting plate, which has a first fixing hole. The cantilever frame has a corresponding second fixing hole, and the first fixing hole and the second fixing hole are connected by bolts. The rotary drive device is fixedly installed on the cantilever frame, which enhances the overall structural stability and ensures the safety of the equipment during operation.

[0009] The rotary drive device uses a swing cylinder to provide precise angle control and improve the overall operating accuracy of the equipment.

[0010] The scissor lift assembly includes a scissor lift carriage, a scissor lift assembly, and a hydraulic cylinder. The hydraulic cylinder is mounted on the scissor lift carriage and drives the scissor lift assembly to move the fork assembly. By driving the scissor lift assembly with the hydraulic cylinder, the fork assembly can be controlled to accurately reach the required position for transport.

[0011] The scissor lift assembly includes a first link and a second link, which are hinged at the midpoint to form an X-shaped structure. The scissor lift assembly maintains high structural stability during extension and retraction.

[0012] The upper end of the first connecting rod is hinged to the fork assembly, and the lower end is hinged to the output end of the hydraulic cylinder; the upper end of the second connecting rod is hinged to the scissor lift, and the lower end is hinged to the fork assembly. The hydraulic cylinder controls the smooth extension and retraction of the scissor lift assembly.
