[0002] With the increasing popularity of electric forklifts, the intelligent control components installed on them are also becoming increasingly diverse. This requires multiple sets of wires to be arranged on forklifts to meet functional requirements. Traditional wiring arrangements require each wire pulley to accommodate only one wire. If multiple wires are required, installing multiple pulleys is complex and has poor durability. Furthermore, damaged wires are difficult to replace and disassemble, resulting in a shorter wire lifespan. Utility Model Content

[0020] Reference Figure 1-5, multiple sets of wire forklift door frames, including an outer door frame 1, an inner door frame 2 is embedded in the outer door frame 1, the outer door frame 1 is fixed to the forklift frame to provide support for the inner door frame 2, the lower front end of the inner door frame 2 is threadedly connected with a fork frame 3, the inner door frame 2 is the core part of the door frame, and can slide up and down in the outer door frame 1, the fork frame 3 on the inner door frame 2 is used to directly carry and lift goods, the inner upper end of the inner door frame 2 is threadedly connected to the upper mounting bracket 8, the support plate of the outer door frame 1 is threadedly connected to the fixing plate 9, the rear side of the fork frame 3 is threadedly connected to the lower mounting bracket 15, the outer surfaces of the fixing plate 9 and the lower mounting bracket 15 are threaded with wire clamps 14, the fixing plate 9 and the lower The surfaces of the mounting brackets 15 are fixed with both ends of the electric wires 17 by wire clamps 14. A detachable fixed shaft 10 is inserted through one end of the upper mounting bracket 8. A pulley 12 movably connected to the outer surface of the fixing plate 9 is sleeved with a pulley 12. A drag chain 13 is wrapped around the outer surface of the pulley 12. One end of the drag chain 13 is threadedly connected to the surface of the fixing plate 9, and the other end of the drag chain 13 is threadedly connected to the surface of the lower mounting bracket 15. When the gantry is raised and lowered normally, the drag chain 13 will rise and fall synchronously with the gantry. At this time, the electric wire 17 moves synchronously inside the drag chain 13. When the electric wire 17 is damaged, the drag chain 13 can be directly disassembled and replaced, which is convenient for disassembly and assembly.

[0021] The outer surface of the fixed shaft 10 is provided with a spacer 11 located between the inner wall of the upper mounting bracket 8 and the pulley 12. When the number of wires 17 increases, it can be achieved by replacing the specifications of the drag chain 13, reducing the size of the spacer 11, and adjusting the installation space.

[0022] The front surface of the fork frame 3 is respectively threadedly connected with a shelf 4 and a fork 16. The fork 16 is installed on the fork frame 3. The shelf 4 is used to insert a pallet or other support at the bottom of the goods, and the fork 16 is used to block the goods to prevent them from falling.

[0023] A pair of oil cylinders 5 are threadedly connected to the bottom of the outer mast 1, and the telescopic ends of the oil cylinders 5 are fixed to the top of the inner mast 2. The oil cylinders 5 are installed between the outer mast 1 and the inner mast 2. The oil cylinders 5 are used to push the inner mast 2 up and down, thereby realizing the lifting of goods.

[0024] A chain 6 is connected between the fork frame 3 and the chain seat on the inner mast 2 to increase the lifting height of the inner mast 2.

[0025] The wires 17 pass through the interior of the drag chain 13 . The wires 17 inside the drag chain 13 can effectively avoid direct contact between the wires 17 and the external environment, play a certain protective role, and increase the service life of the wires 17 .

[0026] The surface of the oil cylinder 5 is threadedly connected to a hose 7, and the other end of the hose 7 is threadedly connected to a hydraulic system. The hose 7 transmits hydraulic oil in the hydraulic system, and the lifting and lowering functions of the forklift are realized by controlling the movement of the oil cylinder 5.

[0027] When the device is in use, when the operator starts the forklift lifting function, the hydraulic system will inject liquid into the oil cylinder 5 through the hose 7, pushing the piston rod of the oil cylinder 5 to rise. The movement of the piston rod of the oil cylinder 5 is transmitted to the sprocket through the chain 6, thereby pulling the fork frame 3 up along the guide rail of the outer mast 1, and at the same time driving the fork 16 and the cargo on it to rise, while the inner mast 2 rises and falls normally, and the drag chain 13 will rise and fall synchronously with the inner mast 2. At this time, the wires 17 move synchronously inside the drag chain 13. At the same time, the wires 17 are inside the drag chain 13, which can effectively prevent the wires 17 from direct contact with the external environment, play a certain protective role, and increase the service life of the wires 17. When the number of wires 17 increases, it can be achieved by replacing the specifications of the drag chain 13, replacing the size of the spacer 11, and adjusting the installation space. When the wires 17 are damaged, they can be directly replaced after disassembling the drag chain 13, which is convenient for disassembly and assembly.
