[0003] In order to solve the above problems, through retrieval, Chinese Patent CN118908112A discloses a forklift for transporting steel coils, including a chassis, a cab, a mast, fork teeth, universal wheels I, mounting sleeves, a lifting device, guide rails I, sliding seats, etc. The cab is installed on the top surface of the chassis, the mast is slidably installed on the chassis, the fork teeth are installed on the side of the mast, the universal wheels I are symmetrically and rotatably installed on both sides of the chassis, the mounting sleeves are slidably installed on the fork teeth, the lifting device is connected to the bottom surface of the mounting sleeve, the guide rails I are symmetrically connected to the inside of the chassis, the sliding seats are slidably connected to the guide rails I, and the top surface of the sliding seat is fixedly connected to the bottom surface of the mast. By detachably installing the mounting sleeve on the fork teeth, the lifting device can be selectively installed or disassembled as needed. When encountering different types of goods or working environments, workers do not need to disassemble the fork teeth to complete the transportation of different types of goods, which is convenient to use.

A bogie wheel set is arranged below each boom frame, and a lifting mechanism for lifting the front part of the vehicle frame is arranged between each bogie wheel set and the corresponding boom frame. A hook device for hooking the inner hole wall surface of the heavy steel coil upward is arranged on each boom frame. The heavy steel coil carrier of the present invention can conveniently load heavy steel coils into containers, and its operation results meet the customary requirements for placing and fixing heavy steel coils in road transportation.

[0006] For another example, Chinese Patent CN212403370U discloses a loading and unloading device suitable for copper and aluminum coil materials. The loading and unloading device includes a string rod, a front plate, and a hanging link plate. Vertically arranged roller mounting plates are respectively provided on the left and right sides of the rear side surface of the front plate. A horizontally arranged hanging link plate is provided between the two roller mounting plates. The hanging link plate is connected to the lifting system of the trolley. Rollers are respectively provided at the upper and lower ends of the outer side surfaces of the two roller mounting plates.

Specifically, the transverse guide rail 11 and the longitudinal guide rail 12 adopt QU80 tracks; the gauge is 1780 mm.

[0074] In this embodiment, the above-mentioned workstation 20 is located at the tail of the transverse guide rail 11, the RGV transporter can run along the longitudinal guide rail 12, and the loading vehicle 30 can run along the transverse guide rail 11.

[0075] Combined with Figure 3 、 Figure 4 、 Figure 5 and Figure 6 shown, this embodiment provides a structure of a loading vehicle 30, the loading vehicle 30 including a vehicle body 31, a traveling mechanism 33 and an actuator 34: the traveling mechanism 33 and the actuator 34 are arranged on the vehicle body 31; the vehicle body 31 includes a base 311, a lifting frame 312, a counterweight 313, a pull rod 314 and a lifting assembly 315: buffer pads and limit switches are arranged at the front and rear ends of the base 311; the counterweight 313 and the lifting frame 312 are respectively arranged on both sides of the base 311; one end of the pull rod 314 is connected to one side of the top of the lifting frame 312, and the other end is connected to the base 311; the lifting frame 312 and the vehicle body 31 adopt a prestressed frame structure design to improve the anti-"tilting head" ability of the cantilever cylinder 3431 when carrying a load.

[0076] In addition, if Figure 7 As shown, the base 311 is designed to be a hollow structure, and concrete or the like can be injected into the hollow part to enhance the supporting strength of the base 311, increase the weight of the base 311, and ensure the stability of loading.

[0086] Furthermore, as Figure 11 shown, the drive assembly 341 includes a bidirectional drive servo motor 3411, a speed reducer 3412, a coupling 3413, a lead screw 3414, and a guide sleeve 3415. The bidirectional drive servo motor 3411, the speed reducer 3412, and the coupling 3413 are fixed on the lifting arm 3151, and the lead screw 3414 cooperates with the guide sleeve 3415; by driving the lead screw 3414 to rotate through the bidirectional drive servo motor 3411, the speed reducer 3412, and the coupling 3413, the lead screw 3414 and the guide sleeve 3415 move relative to each other, and the guide sleeve 3415 drives the support assembly 342 to move in the X direction.

[0087] The cooperation between the above-mentioned lead screw 3414 and the guide sleeve 3415 ensures high precision in the Z direction. At the same time, the cooperation between the double lead screws 3414 and the guide sleeve 3415 makes the movement of the cantilever cylinder 3431 smoother and more accurate.

[0088] In some embodiments of the present invention, the drive assembly 341 can also be driven by an electro-hydraulic cylinder. In comparison, the precision of the electro-hydraulic cylinder is not as good as the cooperation between the lead screw 3414 and the guide sleeve 3415, but it can also meet the usage requirements in some cases, such as an open container 21.

[0089] In addition, as Figure 1 shown, in order to reduce the influence of external dust, etc. on the lead screw 3414 and the guide sleeve 3415, the drive assembly 341 is also externally equipped with a protective cover 3416; the protective cover 3416 is fixed on the lifting arm 3151, and the protective cover 3416 is provided with ventilation holes, which can dissipate the heat generated inside the bidirectional drive servo motor 3411 and prevent the bidirectional drive servo motor 3411 from overheating.

[0090] The loading vehicle 30 of the present invention adopts a rail type, as Figure 6As shown, the traveling mechanism 33 includes a reduction motor 331, a pair of drive wheels 332 connected to the reduction motor 331, and at least a pair of driven wheels 333; the drive wheels 332 and the driven wheels 333 are respectively placed on the guiding unit 10 and can move along the direction of the guiding unit 10. Mechanical limiting plates are provided at both the coil supporting position 14 and the coil loading position 15 of the transverse guide rail 11 to provide further limiting guarantee.

[0091] It should be emphasized that during the process of supporting the steel coil 50, the shaking generated by the loading vehicle 30 is transmitted to the steel coil 50 through the cantilever cylinder 3431. At the same time, relative movement and mutual friction will occur between the inner hole wall of the cantilever cylinder 3431 and the steel coil 50, resulting in damage to the inner hole wall. In this regard, the two pairs of driven wheels 333 of the present invention are arranged in parallel, and the two pairs of driven wheels 333 are specially designed, so that the operation is smoother at the joint of the ground guide rail, effectively solving the above problems and ensuring that the quality of the steel coil 50 meets the requirements as much as possible.

[0092] The loading method for the applicable steel coil 50 of the present invention, using the above-mentioned loading equipment for the applicable steel coil 50, includes the steps: the transportation device 40 transports the steel coil 50 to the coil supporting position 14, and the loading equipment travels to the coil loading position 15; after the loading equipment is matched with the steel coil 50, the steel coil 50 is lifted to a safe height; the loading equipment travels to a position suitable for the inside of the container 21 and unloads the coil; the loading equipment returns to the initial position and waits for the next instruction.

[0093] The present invention and its embodiments are schematically described above. The description is not restrictive, and only one of the embodiments of the present invention is shown in the drawings. The actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative efforts without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
