Abstract
Description
Technical Field
[0001] This invention belongs to the field of towing tooling technology, specifically relating to a forklift chassis towing tooling and its usage method. Background Technology
[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.
[0003] In modern vehicle production and warehousing, the efficiency of chassis transfer directly affects the overall production line's throughput. Currently, short-distance transport of chassis within warehouses, inter-process transfers, or inbound / outbound handling typically rely on specialized trailers and matching positioning fixtures. However, existing chassis transport fixture solutions have significant limitations.
[0004] Existing tooling has a complex structure and is mostly dedicated brackets or supports, resulting in extremely poor versatility. With the continuous expansion and upgrading of product models, warehouses often need to store a large number of different types of dedicated tooling. This "one size, one tooling" model directly leads to redundant tooling on-site, causing a surge in management costs. When changing products, operators need to spend a significant amount of time finding and replacing the corresponding tooling, severely reducing the production line's flexible manufacturing capabilities and logistics response speed. Summary of the Invention
[0005] To address the aforementioned problems, this invention provides a forklift chassis towing fixture and its usage method, which solves the problems of existing fixtures having complex structures and being mostly dedicated brackets or support fixtures, resulting in poor versatility and low replacement efficiency.
[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a forklift chassis towing fixture, comprising: a fixture base for fixing to a forklift, wherein the fixture base is provided with a rotating connecting seat and an anti-detachment hook, the rotating connecting seat and the anti-detachment hook being respectively disposed at both ends of the fixture base; a rotating connecting shaft is mounted on the rotating connecting seat, a chassis connecting seat is disposed at the top end of the rotating connecting shaft, the rotating connecting shaft is composed of a rotating shaft and a rotating limiting plate, the rotating shaft is rotatably mounted in a first rotating hole and a second rotating hole on the rotating connecting seat, and the axial direction of the rotating shaft is perpendicular to the surface of the fixture base, the rotating limiting plate is fixedly disposed at the end of the rotating shaft away from the chassis connecting seat, and the thickness of the rotating limiting plate is less than the gap width formed between the second horizontal fixing plate of the rotating connecting seat and the fixture base; a first locking mechanism is disposed on the side of the chassis connecting seat, and a second locking mechanism is also disposed on the fixture base.
[0007] As a further implementation, the tooling base is a wedge-shaped cavity structure with one end open, and the wedge-shaped cavity structure is adapted to the shape of the forklift forks; the anti-detachment hook is set at the end of the tooling base near the opening.
[0008] As a further implementation, the rotary connecting seat includes two vertical fixing plates, and a first horizontal fixing plate and a second horizontal fixing plate are arranged between the two vertical fixing plates. The first horizontal fixing plate and the second horizontal fixing plate are arranged close to the tooling base in sequence, and the first horizontal fixing plate and the second horizontal fixing plate are arranged in parallel and maintain a set distance. The second horizontal fixing plate is arranged close to the tooling base, and the gap formed between the second horizontal fixing plate and the tooling base is a set size.
[0009] As a further implementation, the first rotating hole is disposed on the first horizontal fixed plate, the second rotating hole is disposed on the second horizontal fixed plate, and the first rotating hole and the second rotating hole are arranged concentrically.
[0010] As a further implementation, the end of the rotating shaft near the chassis connecting seat is also provided with two first reinforcing plates and a second reinforcing plate.
[0011] As a further implementation, both the first reinforcing plate and the second reinforcing plate are triangular steel plates. The two right-angled sides of the first reinforcing plate and the second reinforcing plate are fixedly connected to the bottom surface of the rotating shaft and the chassis connecting seat, respectively. One right-angled side of the first reinforcing plate and the second reinforcing plate are of equal length, and the length of the other right-angled side of the first reinforcing plate is greater than the length of the other right-angled side of the second reinforcing plate.
[0012] As a further implementation, the chassis connecting seat is made of channel steel, and multiple first locking mechanisms are provided on the two side walls of the chassis connecting seat. Each first locking mechanism includes a first locking hole and a first locking element. Each first locking hole is threaded with a first locking element for fixing the chassis to the chassis connecting seat.
[0013] As a further implementation, the second locking mechanism includes a second locking hole and a second locking element. Each second locking hole is threaded with a second locking element for fixing the tooling base to the forklift forks.
[0014] As a further implementation, the anti-detachment hook is an L-shaped plate, one end of which is fixedly connected to the tooling base to form a groove with an opening facing the rotating connecting seat, and a reinforcing rib is provided on the side of the anti-detachment hook away from the rotating connecting seat.
[0015] Secondly, the present invention also provides a method for using a forklift chassis to tow tooling, comprising: Step 1: Install the tooling base onto the forklift forks through the open end. After installation, fix the tooling base onto the forks using the second locking device. Connect the forklift lifting frame to the anti-detachment hook using a chain. Step 2: Use the forks to raise and lower the tooling base to the set height so that the chassis can fall into the chassis mounting base. Use the first locking component to fix the chassis to the chassis mounting base. Use the rotating connecting shaft to realize the steering function when the chassis is transported, and use the rotating connecting shaft to realize the transition of the height difference between the chassis and the tooling base.
[0016] Compared with the prior art, the advantages and positive effects of this invention are: The tooling base of this invention is provided with a rotating connecting seat and an anti-detachment hook, respectively located at both ends of the tooling base; a rotating connecting shaft is mounted on the rotating connecting seat, and a chassis connecting seat is provided at the top of the rotating connecting shaft for connecting the vehicle chassis to be transported. The rotating connecting shaft consists of a rotating shaft and a rotating limiting plate. The rotating shaft is rotatably installed in a first rotating hole and a second rotating hole on the rotating connecting seat, and the axial direction of the rotating shaft is perpendicular to the surface of the tooling base, giving the chassis a certain degree of rotational freedom relative to the forklift forks, ensuring that the vehicle chassis can turn flexibly, and enabling the tooling to adapt. To accommodate different road conditions, the chassis can turn flexibly during transport, avoiding rigid impacts. The thickness of the rotating limit plate is less than the gap width formed between the second horizontal fixed plate of the rotating connecting seat and the tooling base, allowing for vertical movement between the chassis connecting seat and the tooling base. This ensures that the rotating connecting shaft can float within the rotating connecting seat, effectively compensating for bumps and impacts caused by uneven ground or height differences during forklift operation, and preventing chassis twisting or deformation caused by rigid connections. The chassis and forks are connected through the first and second locking mechanisms. Attached Figure Description

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment provides a forklift chassis towing fixture, such as... Figures 1-3As shown, the fixture includes: a tooling base 1 for fixing to a forklift, wherein the tooling base 1 is provided with a rotating connecting seat 3 and an anti-detachment hook 5, the rotating connecting seat 3 and the anti-detachment hook 5 being respectively disposed at both ends of the tooling base 1; a rotating connecting shaft 4 is mounted on the rotating connecting seat 3, and a chassis connecting seat is provided at the top end of the rotating connecting shaft 4; the rotating connecting shaft 4 is composed of a rotating shaft 41 and a rotating limiting plate 42, the rotating shaft 41 being rotatably mounted in a first rotating hole 34 and a second rotating hole 35 on the rotating connecting seat 3, and the axial direction of the rotating shaft 41 being perpendicular to the surface of the tooling base 1. This design allows the chassis to have a certain degree of rotational freedom relative to the forklift forks, enabling the fixture to adapt to different road conditions and maintain the chassis's flexibility during transportation. The rotating limit plate 42 is fixedly installed at the end of the rotating shaft 41 away from the chassis connecting seat, and the thickness of the rotating limit plate 42 is less than the gap width formed between the second horizontal fixing plate 33 of the rotating connecting seat 3 and the tooling base 1. This allows for vertical movement between the chassis connecting seat and the tooling base 1, ensuring that the rotating connecting shaft 4 can float within the rotating connecting seat 3. This effectively compensates for bumps and impacts caused by uneven ground or height differences during forklift operation, and avoids chassis twisting or deformation caused by rigid connections. A first locking mechanism is provided on the side of the chassis connecting seat, and a second locking mechanism is provided on the tooling base 1. The chassis and forks are connected through the first and second locking mechanisms.
[0024] As a further implementation, the tooling base 1 is a wedge-shaped cavity structure with one open end, and the wedge-shaped cavity structure is adapted to the shape of the forklift forks to ensure that there is no violent shaking between the tooling base 1 and the forks, and to ensure the installation stability of the tooling base 1; the anti-detachment hook 5 is set at the end of the tooling base 1 near the opening, so as to facilitate the connection of the tooling base 1 to the forklift through the anti-detachment hook 5 and the iron chain, and to prevent the tooling base 1 from separating from the forks when the second locking mechanism fails.
[0025] As a further implementation, the rotating connecting seat 3 includes two vertical fixing plates 31, with a first horizontal fixing plate 32 and a second horizontal fixing plate 33 disposed between the two vertical fixing plates 31. The first horizontal fixing plate 32 and the second horizontal fixing plate 33 are arranged sequentially close to the tooling base 1, and are arranged parallel to each other and maintain a set distance. The second horizontal fixing plate 33 is disposed close to the tooling base 1, and the gap formed between the second horizontal fixing plate 33 and the tooling base 1 is a set size. This allows for vertical movement between the chassis connecting seat and the tooling base 1, avoiding bumps and impacts caused by uneven ground or height differences during forklift operation, and preventing chassis twisting or deformation caused by rigid connections.
[0026] As a further implementation, the first rotating hole 34 is disposed on the first horizontal fixed plate 32, and the second rotating hole 35 is disposed on the second horizontal fixed plate 33. The first rotating hole 34 and the second rotating hole 35 are arranged concentrically, so that the axial direction of the rotating shaft 41 is always perpendicular to the surface of the tooling base 1, avoiding the rotating shaft 41 from tilting and causing the chassis to become less flexible when turning.
[0027] As a further implementation, two first reinforcing plates 8 and a second reinforcing plate 9 are also provided at the end of the rotating shaft 41 near the chassis connecting seat. The junction of the rotating shaft 41 and the chassis connecting seat is a stress concentration area. Adding the first reinforcing plate 8 and the second reinforcing plate 9 can effectively prevent the rotating shaft 41 from breaking due to excessive torque or bending moment.
[0028] As a further implementation, both the first reinforcing plate 8 and the second reinforcing plate 9 are triangular steel plates, which effectively prevents the chassis connecting seat from tilting or shaking relative to the rotating shaft 41 when under force. The two right-angled sides of the first reinforcing plate 8 and the second reinforcing plate 9 are fixedly connected to the bottom surface of the rotating shaft 41 and the chassis connecting seat, respectively. One right-angled side of the first reinforcing plate 8 and the second reinforcing plate 9 are of equal length, and the length of the other right-angled side of the first reinforcing plate 8 is greater than the length of the other right-angled side of the second reinforcing plate 9, so that the first reinforcing plate 8 can withstand greater bending moment or shear force.
[0029] As a further implementation, the chassis connecting seat is made of channel steel, and multiple first locking mechanisms are provided on the two side walls of the chassis connecting seat. The first locking mechanism includes a first locking hole 6 and a first locking element 7. Each first locking hole 6 is threaded with a first locking element 7 for fixing the chassis to the chassis connecting seat.
[0030] As a further implementation, the second locking mechanism includes a second locking hole 10 and a second locking member 11. Each second locking hole 10 is threaded with a second locking member 11 for fixing the tooling base 1 to the forklift forks.
[0031] As a further implementation, the anti-detachment hook 5 is an L-shaped plate, one end of which is fixedly connected to the tooling base 1 to form a groove with an opening facing the rotating connecting seat 3. The anti-detachment hook 5 is provided with a reinforcing rib on the side away from the rotating connecting seat 3. Since the anti-detachment hook 5 is subjected to a large force at the moment the second locking mechanism fails, the reinforcing rib can effectively prevent the anti-detachment hook 5 from deforming and failing or directly separating from the tooling base 1.
[0032] Example 2 This embodiment provides a method for using a forklift chassis to tow tooling, including: Step 1: Install the tooling base 1 onto the forklift forks through the open end. No complicated lifting equipment is required. The operation can be completed using the existing forklift on site. After installation, fix the tooling base 1 onto the forks with the second locking part 11. Connect the forklift lifting frame and the anti-detachment hook 5 with an iron chain to form secondary protection and effectively prevent the tooling from falling off the forks or tipping over. Step 2: Use the forks to raise and lower the tooling base 1 to a set height so that the chassis can fall into the chassis fixing seat 2. Use the first locking member 7 to fix the chassis to the chassis fixing seat 2. Use the rotating connecting shaft 4 to realize the steering function when the chassis is transported. Use the rotating connecting shaft 4 to realize the transition of the height difference between the chassis and the tooling base 1.
[0033] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
