Description

Technical Field

[0001] This utility model relates to the field of forklift fork plate technology, specifically a reinforced forklift fork plate mounting structure. Background Technology

[0002] As a crucial piece of equipment in modern logistics handling, the stability and adjustability of the fork structure of forklifts directly affect operational efficiency and safety. Current forklift fork mounting structures generally suffer from the following technical problems:

[0003] First, traditional fork spacing adjustment mechanisms often employ simple sliding structures, which are prone to skewing and jamming under heavy loads. Due to the lack of an effective multi-guided mechanism, the forks are prone to wobbling during movement, affecting operational accuracy, accelerating component wear, and shortening equipment lifespan.

[0004] Secondly, the transmission systems of existing fork spacing adjustment mechanisms generally suffer from low efficiency. Common gear and rack or chain drives are prone to developing backlash after prolonged use, leading to a decrease in adjustment accuracy. Especially under frequent adjustment conditions, the wear of transmission components will be further accelerated, affecting the stable operation of the equipment.

[0005] Furthermore, the traditional forklift tilting mechanism lacks structural rigidity. When handling heavy objects, the single support structure is prone to deformation, affecting the stability of the goods. At the same time, the smoothness of the tilting mechanism's movement needs improvement to prevent accidental slippage of goods during lifting.

[0006] Furthermore, the frictional resistance in existing sliding friction structures increases significantly after long-term use, which not only increases motor energy consumption but may also lead to difficulties in adjustment. Especially under harsh operating conditions, the intrusion of dust and debris will further aggravate frictional losses and affect the normal operation of the equipment.

[0007] To address the aforementioned technical problems, there is an urgent need to develop a new forklift fork mounting structure to solve the problems of insufficient guiding stability, low transmission efficiency, lack of structural rigidity, and severe friction loss in existing technologies. Utility Model Content

[0008] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a reinforced forklift fork plate mounting structure that is structurally stable, precisely adjustable, and has a strong load-bearing capacity.

[0009] The technical solution adopted by this utility model to achieve the above objectives is as follows: a reinforced forklift fork plate mounting structure, including a slot box, U-shaped sliders, a translation rod, forks, and a bidirectional threaded rod. The slot box is the core support structure of the device. Two sets of symmetrical U-shaped sliders are slidably connected inside the slot box. The U-shaped sliders are slidably connected to guide rods to realize the horizontal movement of the translation rods and forks, thereby adjusting the fork spacing. The two ends of the guide rods are respectively fixedly connected to the inner wall of the slot box. The lower end of the U-shaped sliders is fixedly connected to the translation rod. A drive block is fixedly connected to the middle of the translation rod. A threaded hole is passed through the drive block. A bidirectional threaded rod is rotatably connected inside the slot box. The drive blocks are respectively threadedly connected to the bidirectional threaded rod. By rotating the drive blocks at both ends, the U-shaped sliders move synchronously in opposite directions. The system enables electric adjustment of the fork spacing. First sliding guide blocks are fixedly connected to both sides of the translation rod located above the drive block. These first sliding guide blocks are slidably connected to first sliding rails, which are fixedly connected to the inner walls of both sides of the slot box. Second sliding guide blocks are fixedly connected to both sides of the translation rod below the drive block. These second sliding guide blocks are slidably connected to second sliding rails, which are also fixedly connected to the inner walls of both sides of the slot box. The cooperation between the first sliding guide blocks and the first sliding rails, and between the second sliding guide blocks and the second sliding rails, ensures that the translation rod remains horizontal during movement, preventing tilting or jamming and improving the stability of the translation rod's movement. A slot is provided at the lower end of the slot, through which the lower end of the translation rod passes and is fixedly connected to a mounting block. The lower end of the mounting block is fixedly connected to one end of the fork.

[0010] In the above technical solution, a guide roller is rotatably connected inside the U-shaped slider, and the lower end of the guide roller is rolledly connected to the guide rod. Two sets of sliding guide wheels are rotatably connected inside the U-shaped slider below the guide roller, and the upper ends of the sliding guide wheels are rolledly connected to the guide rod.

[0011] In the above technical solution, a worm gear is fixedly connected to the middle of the bidirectional threaded rod, a worm is meshed with one side of the worm gear, both ends of the worm are rotatably connected to the inner wall of the trough, one end of the worm passes through the trough and is fixedly connected to the first bevel gear, the first bevel gear is meshed with the second bevel gear, the second bevel gear is fixedly connected to the end of the shaft of the drive motor, and the drive motor is fixedly connected to one side of the outer wall of the trough.

[0012] In the above technical solution, two sets of symmetrical mounting plates are fixedly connected to the outer wall of one side of the tank. A fixing rod is fixedly connected to one side of the mounting plate. A rotating shaft block is fixedly connected to the lower end of the fixing rod. The rotating shaft block is rotatably connected to the lower end of the forklift frame.

[0013] In the above technical solution, a rotating groove is provided on one side of the fixed rod, and a hydraulic cylinder is rotatably connected in the rotating groove. The other end of the hydraulic cylinder is rotatably connected to the forklift frame.

[0014] The beneficial effects of this utility model are:

[0015] 1. By employing a three-point guiding structure consisting of guide rollers and two sets of sliding guide wheels, the U-shaped slider achieves smooth rolling motion on the guide rod. This unique design transforms traditional sliding friction into rolling friction, effectively reducing motion resistance and making fork spacing adjustment smoother. Simultaneously, the three-point contact layout significantly improves resistance to off-center loads, maintaining stable guiding performance even under heavy load conditions and avoiding the jamming problems common in traditional single-rail structures.

[0016] 2. The innovative bidirectional threaded rod combined with the worm gear transmission system ensures high precision and reliability in fork spacing adjustment. The worm gear mechanism has a self-locking characteristic, which effectively prevents accidental displacement of the forks after adjustment stops, improving operational safety. This transmission system, through a multi-stage reduction design, achieves smooth and precise spacing adjustment while ensuring sufficient driving force, solving the problems of backlash and decreased accuracy that are common in traditional transmission methods.

[0017] 3. The design employs a combination of upper and lower double sliding guide blocks and a sliding rail, providing comprehensive motion constraints for the translation rod. The first and second sliding guide blocks form a double guide above and below the drive block, effectively preventing tilting and swaying of the translation rod during movement. This design significantly enhances the rigidity of the overall structure, making it particularly suitable for heavy-duty handling operations and significantly improving the stability and service life of the equipment.

[0018] 4. The optimized hydraulic tilting mechanism provides a stable pivot point for the forks through a rigid connection between the pivot block and the fixed rod. The hydraulic cylinder's connection via a rotating slot ensures both sufficient driving force and smooth angle adjustment. This structure overcomes the shortcomings of insufficient rigidity in traditional tilting mechanisms, maintaining stable tilting performance even under heavy loads and effectively preventing cargo slippage.

[0019] 5. The overall structure adopts a modular design, allowing for independent maintenance and replacement of major components such as the U-shaped slider, guide rod, and transmission system. This design significantly reduces the difficulty and cost of equipment maintenance, improving its economic efficiency. Simultaneously, the rational and compact structural layout achieves a comprehensive performance improvement without increasing the overall size, demonstrating excellent practicality and widespread applicability.
