[0036] Embodiment 1

[0037] In this embodiment, by providing a matching lead screw ball nut and a threaded lead screw, and driving the rotation of the lead screw through a driving component, the fork arm assembly connected to the lead screw nut is further guided to move axially along the lead screw. The distance between the fork arm assemblies is adjusted, thereby realizing the adjustability of the distance of the goods fork platform. This design enables the goods fork platform to adapt to goods of different sizes and distances, greatly improving the flexibility and practicality of the goods fork platform.

[0038] A goods fork platform with adjustable spacing, as shown in the attached Figure 1 figure, includes: a mounting mechanism 1, at least two groups of fork arm assemblies 2, a lead screw nut 3, a lead screw 4, and a driving component 5;

[0039] At least one fork arm assembly 2 is connected with a screw nut 3; both ends of the screw rod 4 after passing through all the screw nuts 3 are movably connected to the mounting mechanism 1; the screw rod 4 is threadedly connected to the screw nut 3; the screw rod 4 is movably connected to the fork arm assembly 2 not provided with the screw nut 3;

[0040] The driving assembly 5 is arranged on the mounting mechanism 1, and the driving assembly 5 drives the connecting screw rod 4 to rotate the screw rod 4, thereby adjusting the distance between the fork arm assembly 2 connected with the screw rod nut 3 and other fork arm assemblies 2.

[0041] This embodiment provides a forklift platform with adjustable spacing, which is exquisitely designed and highly practical, and includes a mounting mechanism 1, at least two sets of fork arm assemblies 2, a screw nut 3, a screw 4 and a drive assembly 5.

[0042] The mounting mechanism 1 is the cornerstone of the entire forklift platform, providing a solid support and installation foundation for other components. The fork arm assembly 2 is the key part for forking and carrying goods, and the number of these components can be adjusted according to actual needs. At least one of the fork arm assemblies 2 is connected to the lead screw nut 3. The lead screw nut 3 is a component that can move along the threaded trajectory of the lead screw 4. The thread inside it cooperates with the thread of the lead screw 4 to achieve linear motion of the lead screw nut 3 on the lead screw 4. The lead screw 4 runs through all the lead screw nuts 3, and both ends of them are movably connected to the mounting mechanism 1 to ensure that the lead screw 4 can rotate freely without affecting the stability of the mounting mechanism 1.

[0043] For those fork arm assemblies 2 that are not directly connected to the screw nut 3, a movable connection is also adopted between the screw 4 to ensure that these fork arm assemblies 2 can remain relatively still when the screw 4 rotates and do not participate in the adjustment of the spacing. In this embodiment, the screw nut fixing seat 23 on the left fork arm assembly 6 is fixedly connected to the screw nut 3, so that the left fork arm assembly 6 approaches or moves away from the right fork arm assembly 7 along the screw 4 under the drive of the driving assembly 5. If in actual application, the left fork arm assembly 6 and the right fork arm assembly 7 are both provided with a screw nut fixing seat 23 fixedly connected to the screw nut 3, the spacing between the left fork arm assembly 6 and the right fork arm assembly 7 can be adjusted by setting different pitches for the screw nuts 3 of the two.

[0044] The driving assembly 5 is mounted on the mounting mechanism 1 and is directly connected to the screw 4, responsible for driving the screw 4 to rotate. When the driving assembly 5 is started, it will drive the screw 4 to rotate, and then the fork arm assembly 2 connected to the screw nut 3 will move along its axial direction under the guidance of the screw 4. The spacing between the fork arm assembly 2 connected to the screw nut 3 and other fork arm assemblies 2 is adjusted, thereby realizing the adjustability of the spacing of the forklift platform. This design enables the forklift platform to adapt to goods of different sizes and spacings, greatly improving the flexibility and practicality of the forklift platform.

[0045] In a specific embodiment, the fork arm assembly 2 provided with the lead screw nut 3 includes a fork arm 21, a moving arm 22, and a lead screw nut fixing seat 23. The lead screw nut fixing seat 23 is arranged on the moving arm 22, and the moving arm 22 of the fork arm assembly 2 is fixedly connected to the lead screw nut 3 through the lead screw nut fixing seat 23;

[0046] The fork arm 21 is fixedly connected to the side of the moving arm 22 away from the mounting mechanism 1.

[0047] In this embodiment, the fork arm assembly 2 mainly consists of three parts: the fork arm 21, the moving arm 22, and the lead screw nut fixing seat 23. These three work together to enable the fork arm assembly 2 to flexibly adjust its position as needed. The lead screw nut fixing seat 23 is ingeniously installed on the moving arm 22, playing a key connecting role to ensure that the moving arm 22 can be firmly fixed to the lead screw nut 3 and move along with the movement of the lead screw nut 3. In this way, the moving arm 22 can follow the lead screw nut 3 and perform precise linear motion under the drive of the lead screw 4.

[0048] The fork arm 21 is fixed to the side of the moving arm 22 away from the mounting mechanism 1. This design enables the fork arm 21 to move along with the movement of the moving arm 22, thereby achieving precise adjustment of the distance between goods. The fork arm 21 is the part of the goods fork platform that directly contacts and bears the goods, so its stability and precision are crucial for the performance of the entire goods fork platform.

[0049] In a specific embodiment, the fork arm assembly 2 includes a left fork arm assembly 6 and a right fork arm assembly 7, and the length direction of the moving arm 22 of the left fork arm assembly 6 is parallel to the length direction of the moving arm 22 of the right fork arm assembly 7.

[0050] In this embodiment, as shown in the appendix Figure 3 The fork arm assembly 2 includes a left fork arm assembly 6 and a right fork arm assembly 7. The design of these two assemblies is aimed at ensuring that they can work together to efficiently and stably carry and move goods. Each of the left fork arm assembly 6 and the right fork arm assembly 7 includes a moving arm 22, and the length directions of these two moving arms are parallel, which not only ensures the stability of the fork arm assembly during movement but also enables the left and right fork arms to remain synchronized, avoiding unnecessary misalignment or distortion when adjusting the distance.

[0051] This design not only enhances the overall structural strength of the goods fork platform but also improves its operation precision and reliability. By keeping the length directions of the moving arms 22 of the left fork arm assembly 6 and the right fork arm assembly 7 parallel, the goods fork platform can more flexibly cope with various challenges in various working environments, ensuring the safety and stability of the goods during transportation.

[0052] In a specific embodiment, a first lead screw support assembly 11, a first lead screw fixing seat 12, a second lead screw fixing seat 13, and a second lead screw support assembly 14 are sequentially arranged on the mounting mechanism 1; through holes matching the lead screw are respectively arranged on the first lead screw support assembly 11, the second lead screw support assembly 14, the first lead screw fixing seat 12, and the second lead screw fixing seat 13; the lead screw 4 sequentially passes through the first lead screw support assembly 11, the first lead screw fixing seat 12, the second lead screw fixing seat 13, and the second lead screw support assembly 14.

[0053] In this embodiment, multiple components closely related to the lead screw 4 are ingeniously configured on the mounting mechanism 1 to ensure the stability and smooth rotation of the lead screw 4. These components include the first lead screw support assembly 11, the first lead screw fixing seat 12, the second lead screw fixing seat 13, and the second lead screw support assembly 14 which are sequentially installed.

[0054] Through this design, the lead screw 4 can sequentially pass through the first lead screw support assembly 11, the first lead screw fixing seat 12, the second lead screw fixing seat 13, and the second lead screw support assembly 14 to form a stable support structure. This structure not only enhances the fixing and stability of the lead screw 4 but also ensures the smoothness and accuracy of the lead screw 4 during rotation, providing a strong guarantee for the normal operation of the goods fork platform.

[0055] In a specific embodiment, the drive assembly 5 includes a drive part 51, a reduction device 52, a first transmission wheel 53, a second transmission wheel 54, and a transmission chain 55; the drive part 51 is drivingly connected to the reduction device 52, the output end of the reduction device 52 is drivingly connected to the first transmission wheel 53, the second transmission wheel 54 is sleeved on the lead screw 4, and the transmission chain 55 is respectively sleeved on the first transmission wheel 53 and the second transmission wheel 54.

[0056] In this embodiment, as shown in the appendix Figure 2 The drive assembly 5 mainly consists of a drive part 51, a reduction device 52, a first transmission wheel 53, a second transmission wheel 54, and a transmission chain 55. These components cooperate together to ensure that the lead screw 4 can rotate stably and efficiently.

[0057] The driving unit 51 serves as the power source of the entire driving assembly and generates a rotational torque through a certain driving method (such as motor driving). This torque is then transmitted to the reduction gear 52. The main function of the reduction gear 52 is to reduce the rotational speed and increase the torque to ensure that the first driving wheel 53 can obtain sufficient driving force. The output end of the reduction gear 52 is tightly connected to the first driving wheel 53 to ensure that the rotational torque generated by the driving unit 51 can be smoothly transmitted to the first driving wheel 53. As one of the key components of the transmission system, the rotation of the first driving wheel 53 will drive the movement of the transmission chain 55. At the same time, the second driving wheel 54 is sleeved on the lead screw 4, which means that when the second driving wheel 54 rotates, the lead screw 4 will also rotate accordingly. To achieve the linkage between the first driving wheel 53 and the second driving wheel 54, the transmission chain 55 is sleeved on the two driving wheels respectively. When the driving unit 51 is started, through the transmission of the reduction gear 52, the first driving wheel 53 and the transmission chain 55, the second driving wheel 54 starts to rotate, and then drives the rotation of the lead screw 4.

[0058] In a specific embodiment, it further includes a main control unit 8 and a distance measuring sensor 9 for measuring the distance of at least one fork arm assembly 2 connected with a lead screw nut 3. The main control unit 8 is arranged on the mounting mechanism 1, and the distance measuring sensor 9 is arranged on the fork arm assembly 2. The main control unit 8 is electrically connected to the distance measuring sensor 9 and the driving assembly 5 respectively.

[0059] In this embodiment, in order to further improve the intelligence and automation level of the goods fork platform, two key components, namely the main control unit 8 and the distance measuring sensor 9, are also introduced. The main control unit 8 is arranged on the mounting mechanism 1 for centralized control and management of the entire system. The distance measuring sensor 9 is a key component for accurately measuring the distance of the fork arm assembly 2. It is installed on the fork arm assembly 2 and can measure the distance between the fork arm assemblies 2 in real time and feedback the measurement data to the main control unit 8. The introduction of the distance measuring sensor 9 enables the goods fork platform to more accurately judge the position and size of the goods, so as to perform more precise fork-taking and moving operations.

[0060] In order to achieve information interaction and instruction transmission between the main control unit 8, the distance measuring sensor 9 and the driving assembly 5, the main control unit 8 is electrically connected to the distance measuring sensor 9 and the driving assembly 5 respectively. This connection method ensures the rapid and accurate transmission of data, enabling the main control unit 8 to receive the measurement data from the distance measuring sensor 9 in real time and precisely control the driving assembly 5 according to the data.

[0061] In a specific embodiment, it further includes an upper guide shaft 15 and a lower guide shaft 16; both ends of the upper guide shaft 15 and the lower guide shaft 16 are fixedly connected to the mounting mechanism 1;

[0062] Each fork arm assembly 2 is provided with an upper guide shaft fixing seat 17 matching the upper guide shaft 15 and a lower guide shaft fixing seat 18 matching the lower guide shaft 16;

[0063] The upper guide shaft 15 passes through each upper guide shaft fixing seat 17 and is slidably connected to the upper guide shaft fixing seat 17; the lower guide shaft 16 passes through each lower guide shaft fixing seat 18 and is slidably connected to the lower guide shaft fixing seat 18 to maintain stability when adjusting the distance between the fork arm assemblies 2.

[0064] In this embodiment, in order to ensure that the fork arm assembly can maintain stability and reduce shaking when adjusting the distance, two auxiliary components, the upper guide shaft 15 and the lower guide shaft 16, are particularly introduced. Both ends of these two guide shafts are firmly fixed and connected to the mounting mechanism 1, forming a stable guiding system.

[0065] To cooperate with this guiding system, each fork arm assembly 2 is particularly provided with an upper guide shaft fixing seat 17 matching the upper guide shaft 15 and a lower guide shaft fixing seat 18 matching the lower guide shaft 16. These fixing seats not only provide an accurate guiding path for the guide shafts, but also ensure the stability and accuracy of the fork arm assembly during movement.

[0066] Specifically, the upper guide shaft 15 passes through the upper guide shaft fixing seat 17 of each fork arm assembly 2 and is slidably connected to the fixing seat. This means that when the fork arm assembly 2 moves under the drive of the lead screw, the upper guide shaft 15 slides inside the upper guide shaft fixing seat 17, providing stable upward support for the fork arm assembly 2. Similarly, the lower guide shaft 16 passes through the lower guide shaft fixing seat 18 of each fork arm assembly 2 and is also slidably connected to the fixing seat. This enables the fork cargo platform to maintain stability when adjusting the distance between the fork arm assemblies, thereby greatly improving the accuracy and safety of fork-lifting goods.

[0067] In a specific embodiment, the length directions of the upper guide shaft 15, the lower guide shaft 16, and the lead screw 4 are parallel. To ensure the stability and accuracy of the fork arm assembly during movement, the length directions of the upper guide shaft 15, the lower guide shaft 16, and the lead screw 4 are carefully set to be parallel. This ensures that the fork arm assembly moves in a straight line under the drive of the lead screw 4, thus avoiding possible offsets or twists. The parallel arrangement of the upper guide shaft 15 and the lower guide shaft 16 enables the fork arm assembly to be supported evenly and stably during movement, further enhancing the stability and reliability of the fork cargo platform. At the same time, this parallel design also makes the structure of the entire fork cargo platform more compact and stable, improving the overall load-bearing capacity and service life.

[0068] In a specific embodiment, the lead screw nut 3 includes a lead screw ball nut. A threaded portion matching the lead screw ball nut is provided on the outer surface of the lead screw 4, and the lead screw 4 is rotatably connected to the lead screw ball nut.

[0069] In this embodiment, as shown in the appendix Figure 4 The lead screw nut 3 adopts an efficient and durable component, the lead screw ball nut. As an advanced form of the lead screw nut, multiple balls are integrated inside the lead screw ball nut. These balls form rolling contacts between the lead screw nut and the lead screw, significantly reducing the frictional resistance and making the movement of the lead screw nut on the lead screw smoother and more efficient. In order to achieve precise cooperation with the lead screw ball nut, a threaded portion matching the lead screw ball nut is specially provided on the outer surface of the lead screw 4. The design of these threaded portions is precise, forming a tight rolling contact with the balls inside the lead screw ball nut, ensuring the stability and precision of the rotation of the lead screw ball nut on the lead screw.

[0070] When the lead screw 4 rotates driven by the drive assembly, the lead screw ball nut will rotate on the threaded portion of the lead screw, and then achieve its linear movement on the lead screw. This way of rotational connection not only ensures the stable movement of the lead screw ball nut on the lead screw, but also greatly improves the transmission efficiency and precision of the entire goods fork platform.

[0071] In a specific embodiment, as shown in the appendix Figure 5 It also includes a back plate 10. The back plate 10 is detachably connected to the side of the mounting mechanism 1 away from the fork arm assembly 2, and a connecting piece for connecting an external device is provided on the back plate 10.

[0072] The back plate 10 is arranged on the side of the mounting mechanism 1 away from the fork arm assembly 2 and is fixed by a detachable connection method. This enables the back plate 10 to be conveniently disassembled and installed when needed to meet the requirements of different operations or transports. Further, a connecting piece for connecting an external device is provided on the back plate 10. These connecting pieces may be screw holes, card slots, or other standard interface forms to enable quick and stable connection with other devices or tools. Through the connecting pieces on the back plate 10, the goods fork platform can be easily connected to external devices (such as shelves, conveyor belts, lifting platforms, etc.), thereby expanding its usage functions and scope.

[0073] The utility model adjusts the distance between the fork arm assemblies by setting a matching lead screw ball nut and a threaded lead screw, and driving the rotation of the lead screw through a drive assembly, thereby enabling the fork arm assembly connected to the lead screw nut to move axially along the lead screw. This adjusts the distance between the fork arm assemblies, thus realizing the adjustability of the distance of the goods fork platform. This design enables the goods fork platform to adapt to goods of different sizes and distances, greatly improving the flexibility and practicality of the goods fork platform.

[0074] The above is a specific description of the preferred embodiment of the present utility model. However, the present utility model is not limited to the embodiments. Those skilled in the art can also make various equivalent deformations or substitutions without departing from the spirit of the present utility model. These equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
