Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel coil technology, and in particular to a long-distance forklift for transporting steel coils. Background Technology

[0002] Cold-rolled stainless steel is a type of stainless steel material produced through a cold rolling process. It features high strength, good work hardening properties, high surface quality requirements, and a wide variety of varieties and specifications; it is widely used in multiple fields. In cold-rolled stainless steel and silicon steel production lines, since both incoming materials and finished products are in coil form, steel coils completed on one production line in the production workshop need to be transferred to the finished product warehouse area or the uncoiling position of another production line, which requires hoisting the steel coils.

[0003] Currently, for short-distance transportation of stainless steel coils, unloading trolleys are generally used for transfer; for long-distance transportation, overhead cranes are used for hoisting or truck transport. This ensures the stainless steel coils are transported to the required location for convenient subsequent processing.

[0004] However, existing stainless steel coil hoisting requires a large number of operators to work together, resulting in high labor intensity, frequent lifting, high safety risks, and high energy consumption. In particular, for existing steel strip processing workshops, the large space occupied by pipes and platforms is not conducive to lifting and operation, affecting transfer efficiency. Therefore, a long-distance transfer forklift for steel coils is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a long-distance forklift for transporting steel coils, aiming to improve the problems of complex structure, high labor intensity for workers, and low equipment efficiency in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A long-distance forklift for transporting steel coils includes a track, a base, and a placement platform. An adjustment mechanism is installed on the top of the base, and a forklift mast is installed on the top of the adjustment mechanism. A lifting assembly is installed inside the forklift mast. Multiple movable wheels are rotatably connected to the bottom of the base. The multiple movable wheels are located on the top of the track. A driven wheel set is installed on one side of each movable wheel, and a motor is installed on one side of the driven wheel set.

[0008] The adjustment mechanism includes a drive component and a sliding component. The sliding component includes multiple guide rails, which are fixedly connected to the top of the vehicle base. Each of the multiple guide rails has a slider slidably connected to its top. The forklift mast is fixedly connected to the top of the multiple sliders.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes two racks, which are fixedly connected to the top of the vehicle base. Two motors are installed on the upper part of the forklift mast. Gears are fixedly connected to the output ends of the two motors, and the two gears mesh with the two racks respectively.

[0011] As a further description of the above technical solution:

[0012] The lifting assembly includes a fork carriage, which is slidably connected to the inside of the forklift mast. A fork rod is fixedly connected to one side of the fork carriage, and multiple composite guide wheels are rotatably connected to both sides of the fork carriage. Two guide grooves are opened on the inside of the forklift mast, and the multiple composite guide wheels are rotatably connected inside the guide grooves. A hydraulic cylinder is installed on the inside of the forklift mast, and a lifting block is fixedly connected inside the fork carriage. The moving end of the hydraulic cylinder abuts against the lifting block, and a hydraulic actuator is installed on the top of the vehicle base.

[0013] As a further description of the above technical solution:

[0014] Multiple positioning blocks are fixedly connected to the top of the vehicle base, and the multiple positioning blocks are located between the rack and the guide rail;

[0015] As a further description of the above technical solution:

[0016] Multiple rail clamps are fixedly connected to both ends of the vehicle base, and the rail clamps are slidably connected to both sides of the rail.

[0017] As a further description of the above technical solution:

[0018] Limit blocks are fixedly connected to both ends of the track, and anti-collision seats are fixedly connected to both sides of the vehicle base.

[0019] As a further description of the above technical solution:

[0020] A cable chain is installed on the top of the vehicle base, and the cable chain is located on one side of the forklift mast.

[0021] As a further description of the above technical solution:

[0022] The fork is externally connected to a cold-rolled steel coil.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, a sliding assembly consisting of guide rails and sliders is installed on the top of the chassis base, and a drive assembly consisting of rack and pinion is used in conjunction with this assembly to achieve smooth and precise sliding adjustment of the forklift mast on the chassis base. This structural design allows the forklift mast to flexibly adjust its position according to actual working conditions, effectively adapting to the loading and unloading needs of steel coils of different specifications, and improving the versatility and operational adaptability of the equipment. At the same time, the fixing blocks installed on the chassis base can limit the movement range of the forklift mast, preventing excessive movement of the forklift mast.

[0025] 2. In this utility model, the lifting assembly installed inside the forklift mast uses a hydraulic cylinder to drive the lifting block, which in turn pushes the forklift along the guide groove to lift and lower the steel coil smoothly. This not only ensures the guiding accuracy during the lifting process of the forklift and reduces running resistance, but also effectively avoids jamming and improves the smoothness of operation. The moving wheels at the bottom of the chassis run along a fixed track and are equipped with motor-driven driven wheel sets, ensuring the smooth and efficient operation of the forklift during long-distance transport. The cooperation between the rail clamp and both sides of the track effectively prevents the forklift from deviating or derailing during operation. The limit blocks at both ends of the track cooperate with the anti-collision seats on both sides of the chassis to provide double protection when the forklift reaches its travel limit, effectively avoiding equipment collision damage and extending the service life of the equipment. The cable chain design effectively manages and protects the cables or hydraulic lines moving with the mast, preventing them from wearing or getting tangled during operation, improving the reliability and maintenance convenience of the system.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 This utility model provides an embodiment of a long-distance steel coil transport forklift, comprising a track 1, a base 2, and a placement platform 11. The track 1 is laid on the ground, serving as the basic path for the transport forklift's operation. An adjustment mechanism is installed on the top of the base 2, and a forklift mast 3 is installed on top of the adjustment mechanism. A lifting assembly is installed inside the forklift mast 3. Multiple movable wheels 23 are rotatably connected to the bottom of the base 2, located on top of the track 1. A driven wheel set 16 is installed on one side of each movable wheel 23, and a second motor 15 is installed on one side of each driven wheel set 16. The transport forklift consists of the base 2 and multiple movable wheels 23. The movable wheels 23 are installed at the bottom of the base 2 and operate in conjunction with the track 1. The driven wheel set 16 on one side of the movable wheels 23 is driven by the second motor 15, enabling the automatic operation of the transport forklift along the track 1. This method is suitable for long-distance, high-frequency steel coil transfer tasks.

[0036] The adjustment mechanism includes a drive assembly and a sliding assembly. The sliding assembly includes multiple guide rails 6, which are fixedly connected to the top of the base 2. Each guide rail 6 has a slider 22 slidably connected to its top. The guide rails 6 are fixed to the top of the base 2, allowing the sliders 22 to slide on them. The forklift mast 3 is fixedly connected to the top of the sliders 22, enabling it to move. The drive assembly includes two racks 18, which are fixedly connected to the top of the base 2 on both sides. Two motors 5 are mounted on the upper part of the forklift mast 3, on both sides. Gears 21 are fixedly connected to the output ends of each motor 5, and these gears 21 mesh with the two racks 18. The motors 5 drive the gears 21 to rotate, achieving automatic adjustment of the forklift mast 3's position through meshing with the racks 18. Multiple positioning blocks 24 are fixedly connected to the top of the base 2. The multiple positioning blocks 24 are located between the rack 18 and the guide rail 6. The positioning blocks 24 assist in positioning and improve the adjustment accuracy.

[0037] Reference Figures 2-6 The lifting assembly includes a fork carriage 4, which is slidably connected to the inside of the forklift mast 3. The fork carriage 4 moves and adjusts its position inside the forklift mast 3. A fork lever 19 is fixedly connected to one side of the fork carriage 4, and the fork lever 19 is used to lift the cold-rolled steel coil 12. Multiple composite guide wheels 20 are rotatably connected to both sides of the fork carriage 4. Two guide grooves 17 are opened on the inside of the forklift mast 3, and the multiple composite guide wheels 20 are rotatably connected inside the guide grooves 17. The composite guide wheels 20 and the guide grooves 17 cooperate with each other to make the fork carriage 4 move smoothly. A hydraulic cylinder 9 is installed inside the forklift mast 3, and the fork carriage 4 is fixed inside. A lifting block 25 is connected, and the moving end of the hydraulic cylinder 9 abuts against the lifting block 25. When the hydraulic cylinder 9 extends or retracts, it pushes the lifting block 25 to move, thereby moving the fork carriage 4. A hydraulic actuator 7 is installed on the top of the base 2. The cold-rolled steel coil 12 is externally connected to the fork 19. The hydraulic actuator 7 controls the hydraulic cylinder 9, which pushes the lifting block 25 to move the fork carriage 4. The fork carriage 4 slides on the guide groove 17 on the inner side of the forklift mast 3 through the composite guide wheels 20 on both sides, thereby driving the fork carriage 4 to rise or fall, thus realizing the lifting and lowering operation of the cold-rolled steel coil 12.

[0038] Reference Figure 1 and Figure 2Multiple rail clamps 13 are fixedly connected to both ends of the chassis 2. The rail clamps 13 are slidably connected to both sides of the rail 1. The cooperation between the rail 1 and the forklift is achieved through the rail clamps 13, enhancing the guidance and stability during operation. Limit blocks 10 are fixedly connected to both ends of the rail 1. The limit blocks 10 are used to limit the extreme positions of the forklift's operation and prevent derailment. Anti-collision seats 14 are fixedly connected to both sides of the chassis 2. The anti-collision seats 14 prevent the chassis 2 from hitting the limit blocks 10 and are used to buffer collisions and protect the forklift. A cable chain 8 is installed on the top of the chassis 2. The cable chain 8 is located on one side of the forklift mast 3. The cable chain 8 is arranged on one side of the forklift mast 3 to protect cables or hydraulic lines from tangling or wear.

[0039] Working principle: First, during use, drive motor 215 drives the moving wheels 23 at the bottom of the base 2 to rotate via motor 215 and driven wheel set 16, allowing the moving wheels 23 to move on track 1, thereby moving the entire transfer forklift to the side of the cold-rolled steel coil 12 that needs to be moved. Then, hydraulic actuator 7 controls the lifting and lowering of hydraulic cylinder 9, which drives fork carriage 4 to descend, moving the fork 19 on one side of fork carriage 4 to be flush with the center hole of cold-rolled steel coil 12. Drive motor 5, via... When the output end of motor 5 rotates, it drives gear 21 to rotate. When gear 21 rotates, it drives the forklift mast 3 to move on the guide rail 6 via the slider 22 through the meshing rack 18 on one side. This moves the forklift mast 3 to one side, allowing the fork 19 to be inserted into the center hole of the cold-rolled steel coil 12. Then, the hydraulic actuator 7 moves the fork 4 upward to lift the cold-rolled steel coil 12. The forklift mast 3 is then moved inward. Finally, the cold-rolled steel coil 12 is moved to the required position and lowered by a transfer forklift.

[0040] Secondly, when the forklift moves, the rail clips 13 on both sides of the base 2 are engaged with the outside of the track 1 to prevent the forklift from derailing and ensure stability during movement. The anti-collision seats 14 on both sides of the base 2 can offset the impact force when the base 2 moves to the limit block 10 at both ends of the track 1, preventing the base 2 from hitting the limit block 10 and avoiding equipment collision damage.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
