Description
Technical Field
[0001] This utility model relates to the field of forklifts, and more specifically, to a large tilting forklift for tipping containers. Background Technology
[0002] In container handling and tipping operations, the forks, as the core load-bearing components, need to be securely connected to the hydraulic rotator to ensure efficient torque transmission during tipping and to guarantee smooth and controllable container tipping. However, the existing connection structure design between the forks and the hydraulic rotator has many shortcomings: 1. The connection between the two is generally fixed by a single point or a few connection points, which is not stable enough. In frequent container turning operations, the connection is prone to loosening. Not only can it not effectively transmit torque, causing shaking and loss of control during the turning process, but it may also cause safety hazards due to connection failure. 2. The forks' limiting design for the container is unreasonable, which can easily cause interference when inserting and withdrawing from the bottom holes of the container, and makes installation and maintenance inconvenient, thus reducing operational efficiency. Utility Model Content
[0003] The purpose of this invention is to solve the problems mentioned in the background art and to propose a large tipping fork for tilting containers.
[0004] The technical solution adopted by this utility model to solve its technical problem is: A large tipping fork for tipping containers includes a fork body, a limit plate, and a multi-point connection assembly. The limiting plates are symmetrically welded to the end of the bearing surface of the fork, and the limiting plates have notches. The multi-point connection assembly is welded to the top area of the mounting surface of the fork, and several threaded holes are provided on the multi-point connection assembly. The mounting plate of the hydraulic rotator is firmly locked to the multi-point connection assembly by multiple fixing bolts that mate with the threaded holes one by one.
[0005] Furthermore, the multi-point connection assembly includes a U-shaped upper plate, a U-shaped lower plate, and a reinforcing rod. Both the upper U-shaped plate and the lower U-shaped plate are welded to the top area of the mounting surface of the fork body; Two reinforcing rods are symmetrically distributed about the fork body, and the two ends of the reinforcing rods are welded to the upper U-shaped plate and the lower U-shaped plate, respectively.
[0006] Furthermore, the upper U-shaped plate is symmetrically welded with limiting blocks that are L-shaped in shape and fit against the upper edge of the mounting plate of the hydraulic rotator.
[0007] Furthermore, the fork body is welded with a support plate that is L-shaped and matches the limiting block and is attached to the lower edge of the mounting plate of the hydraulic rotator. The length of the support plate is adapted to the length of the U-shaped lower plate and is located at the lower part of the U-shaped lower plate. The limiting block is symmetrically threaded with fastening screws that match the mounting plate of the hydraulic rotator.
[0008] Furthermore, the main shape of the notch is rectangular, and the side of the limiting plate away from the container has rounded corners.
[0009] Furthermore, triangular reinforcing ribs are added at the welding points of the U-shaped upper plate and lower plate to the fork.
[0010] Furthermore, a wear-resistant layer is provided on the bearing surface of the fork, and a rubber layer is provided on the limiting plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are: Compared to existing technologies, this design achieves efficient and reliable container forklift turning operations through a triple advantage of welding reinforcement, quick-installation locking, and structural optimization: First, the limiting plate, U-shaped upper plate, and U-shaped lower plate are welded to the fork body, and then the support strength is reinforced with reinforcing rods and triangular reinforcing ribs; the hydraulic rotator mounting plate is quickly positioned by aligning the two corners with the limiting block and locked with multiple fixing bolts to ensure a stable connection without loosening during turning. Then, when the forks are inserted into the bottom holes of the container, the notch of the limiting plate can avoid movement interference and ensure smooth operation, demonstrating outstanding performance in structural reliability and operational efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments: like Figures 1 to 4 As shown, a large tipping fork for tipping containers includes a fork body 1, a limiting plate 2, and a multi-point connection assembly. The limiting plate 2 is symmetrically welded to the end of the bearing surface of the fork body 1, and the limiting plate 2 has a notch 21. The multi-point connection assembly is welded to the top area of the mounting surface of the fork 1, and the multi-point connection assembly has several threaded holes 6. The mounting plate of the hydraulic rotator is firmly locked to the multi-point connection assembly by multiple fixing bolts that mate with the threaded holes 6 one by one (the fixing bolts and the hydraulic rotator are not shown in the figure, and the hydraulic rotator is the prior art and will not be improved).
[0014] The structure and working principle of the hydraulic rotator are as follows: Structural composition Blade type: mainly composed of stator block, cylinder block, swing shaft, blades, left and right support plates and left and right cover plates. The stator block is fixed to the cylinder block, and the blades are fixed together with the swing shaft.
[0015] Helical type: The core is the helical pair, which consists of the helical teeth of the piston and the helical teeth of the output shaft, and also includes components such as the cylinder, piston, and bearings.
[0016] Common components: all include a cylinder body (to house hydraulic oil and internal parts), seals (to prevent hydraulic oil leakage), bearings (to ensure smooth shaft rotation), and inlet / outlet ports (to control the flow of hydraulic oil).
[0017] Working principle: Vane type: When hydraulic oil enters from one port, it pushes the vanes to oscillate, which in turn drives the oscillating shaft fixed to the vanes to rotate, achieving rotary motion. By switching the direction of hydraulic oil flow in and out of the ports, the forward and reverse rotation of the oscillating shaft can be controlled. Its rotation angle is usually no more than 280°, providing stable torque for fork tipping.
[0018] Helical type: Hydraulic oil drives the piston in a linear motion. Due to the meshing of the helical teeth between the piston and the output shaft, the linear motion of the piston is converted into the rotational motion of the output shaft, thereby driving the forks to tilt. This structure can achieve 360° rotation and generate high torque in a small space, making it suitable for the heavy-duty tilting requirements of forks.
[0019] Specific implementation of this utility model solution, such as Figures 1 to 4 As shown, the multi-point connection assembly includes a U-shaped upper plate 3, a U-shaped lower plate 4, and a reinforcing rod 5. Both the U-shaped upper plate 3 and the U-shaped lower plate 4 are welded to the top area of the mounting surface of the fork body 1; Two reinforcing rods 5 are symmetrically distributed about the fork body 1, and the two ends of the reinforcing rods 5 are welded to the upper U-shaped plate 3 and the lower U-shaped plate 4, respectively.
[0020] To improve the accuracy of the alignment between the hydraulic rotator mounting plate and the multi-point connection assembly and avoid repeated adjustments, further optimizations to the above-described embodiments are made, such as... Figure 4 As shown, the upper U-shaped plate 3 has symmetrically welded limit blocks 7 on both sides, which are L-shaped in shape and fit against the upper edge of the mounting plate of the hydraulic rotator.
[0021] To further reduce the operational difficulty for workers installing and fixing the hydraulic rotator, the above-described embodiments are further optimized, such as... Figure 5 As shown, a support plate 8 with an L-shaped main body is welded onto the fork body 1. This support plate 8 matches the limiting block 7 and is attached to the lower edge of the mounting plate of the hydraulic rotator. The length of the support plate 8 is adapted to the length of the U-shaped lower plate 4 and is located at the lower part of the U-shaped lower plate 4. The limiting block 7 is symmetrically threaded with fastening screws 9 that match the mounting plate of the hydraulic rotator. In this embodiment, when the upper edge of the mounting plate of the hydraulic rotator contacts the inner wall of the two limiting blocks 7, the support plate 8 will contact the lower edge of the mounting plate of the hydraulic rotator to achieve support. Then, by rotating the fastening screws 9 on both sides of the limiting block 7 in sequence, the position of the mounting plate of the hydraulic rotator can be limited. Subsequently, when installing and fixing the bolts at multiple points, it is not necessary to hold the mounting plate of the hydraulic rotator with your hand at all times. You only need to install the bolts into the multiple threaded holes in sequence, thereby reducing the difficulty of operation and ensuring accurate installation.
[0022] To effectively distribute stress and avoid safety hazards such as scratches that may be caused by sharp edges and corners, further optimizations to the above-described embodiments are made, such as... Figure 1 As shown, the main shape of the notch 21 is rectangular and the side of the limiting plate 2 away from the container has a rounded corner 22.
[0023] In order to distribute the force from the welded part to a larger area of the fork body 1 and reduce local stress, the above embodiment is further optimized by adding triangular reinforcing ribs at the welded joints of the U-shaped upper plate 3 and the U-shaped lower plate 4 with the fork body 1. The triangular reinforcing ribs are not shown in the figure.
[0024] In order to improve the service life of the fork body 1 and avoid hard collisions when the limiting plate 2 and the container come into contact, the above embodiment is further optimized by providing a wear-resistant layer on the bearing surface of the fork body 1 and a rubber layer on the limiting plate 2.
[0025] The working process of this utility model: First, the limiting plate 2, the upper U-shaped plate 3, and the lower U-shaped plate 4 are welded to the fork body 1 respectively. Then, the supporting connection strength is further improved by the reinforcing rod 5 and the triangular reinforcing rib. Next, the upper two corners of the hydraulic rotator mounting plate are aligned with the two limiting blocks 7 and inserted. At this time, the positional relationship between the mounting plate and the upper U-shaped plate 3 and the lower U-shaped plate 4 can be quickly defined. Then, the fixing bolts are used to achieve a multi-point firm lock between the hydraulic rotator mounting plate and the upper U-shaped plate 3 and the lower U-shaped plate 4, so that the connection is less likely to loosen when the container is turned over. Then the forks are driven to extend into the insertion holes at the bottom of the container. At this time, due to the presence of the notch 21, the forks can avoid interference between the limiting plate 2 and other parts on the forks or the container being transported during the movement, especially when performing some complex actions or movements at a certain angle, thus ensuring the normal operation and smooth running of the forks. In summary, this application, through the rational design of multi-point connection components (consisting of U-shaped upper plate 3, U-shaped lower plate 4 and reinforcing rod 5), makes the connection between the hydraulic rotator and the forks more stable and reliable, can efficiently transmit torque, and ensures that the container tilting process is smooth and controllable; In addition, the notch 21 on the limiting plate 2 effectively solves the problem of interference between the forks entering and exiting, while also facilitating installation and maintenance. The welded fit between the U-shaped upper and lower plates and the forks, along with the reinforcing rod 5 and triangular reinforcing ribs, significantly improves the structural strength of the forks, enabling them to withstand the stress impact of frequent tipping operations and extending the service life of the equipment. This design has significant advantages in terms of structural reliability, operational efficiency, and equipment durability, effectively compensating for the shortcomings of existing technologies and meeting the requirements of high efficiency, stability, and low cost for container tipping operations.
