Description

Technical Field

[0001] This utility model belongs to the field of aluminum processing, and in particular relates to a lifting platform with an automatic lifting guardrail and a slitting machine system. Background Technology

[0002] A slitting machine is an aluminum processing device used for precise longitudinal cutting of double-sided aluminum and aluminum alloy foil of a certain thickness, and for neatly winding the cut strips together with ideal tension. A lifting platform is usually installed on the discharge side of the slitting machine. Its main function is to provide operators with an auxiliary standing platform for working at heights, facilitating operations such as cutter adjustment, coil inspection, and equipment maintenance. Operators can control the platform's height using a foot switch, stopping it at any suitable working height.

[0003] In related technologies, such lifting platforms typically lack safety railings. Their primary purpose is to facilitate the delivery of tools, measuring instruments, or other auxiliary equipment to the operator on the platform while they are working. However, this design also presents significant safety hazards: when the platform is raised to a high position, the operator faces the risk of falling, especially when moving or bending over to operate.

[0004] To balance ease of operation and safety, some existing technologies have developed platform designs with fixed guardrails. However, the fixed guardrails make it difficult for operators to access the lifting platform, reducing their work efficiency. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a lifting platform with an automatic lifting guardrail and a slitting machine system to solve the problem that it is inconvenient for operators to enter the lifting platform when a fixed guardrail is installed on the lifting platform in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides a lifting platform with an automatic lifting guardrail, comprising: a mounting base, an operating platform, a first lifting drive assembly, a guardrail, and a second lifting drive assembly; the fixed end of the first lifting drive assembly is disposed on the mounting base, and its output end is connected to the operating platform for driving the operating platform to move up and down relative to the mounting base; the guardrail is disposed on the operating platform; the fixed end of the second lifting drive assembly is disposed on the operating platform, and its output end is connected to the guardrail for driving the guardrail to move up and down relative to the operating platform.

[0007] Optionally, the first lifting drive assembly includes a first drive member, a plurality of first guide sleeves spaced apart on the mounting base, and a plurality of first guide rods spaced apart below the operating platform; the fixed end of the first drive member is mounted on the mounting base, and its output end is connected to the operating platform; each first guide rod corresponds to a first guide sleeve, and each guide rod is slidably inserted into the corresponding first guide sleeve.

[0008] Optionally, the fixing points of multiple first guide sleeves on the mounting base together define a polygonal region, and the fixing end of the first drive member is located at the geometric center of the polygonal region.

[0009] Optionally, the operating platform is rectangular, and the fixed end of the first driving component is located at the geometric center of the operating platform.

[0010] Optionally, the number of first guide sleeves is four.

[0011] Optionally, the second lifting drive assembly includes at least one second drive member, multiple second guide sleeves disposed on the operating platform, and multiple second guide rods disposed on the guardrail; the fixed end of the second drive member is disposed on the operating platform, and its output end is connected to the guardrail; each second guide rod corresponds to a second guide sleeve, and each second guide rod is slidably inserted into the corresponding second guide sleeve.

[0012] Optionally, the operating platform is rectangular, and the guardrail is a U-shaped structure matching the operating platform, which includes a front guardrail and two side guardrails, and the front guardrail and the two side guardrails are connected; the second lifting drive assembly includes two second drive members, four second guide sleeves and four second guide rods; the two second drive members, four second guide sleeves and four second guide rods are symmetrically divided into two groups, respectively corresponding to the side guardrails; the second drive members are located between the two second guide sleeves in the same group to drive the guardrail to lift and lower.

[0013] On the other hand, a slitting machine system is also provided, including a slitting machine and a lifting platform with an automatic lifting guardrail as described above; a receiving groove for accommodating the lifting platform is provided on the ground where the slitting machine is installed, the receiving groove ensuring that the top of the lifting platform is not higher than the ground when it is lowered to its lowest position.

[0014] Optionally, the receiving groove is provided with two spaced-apart mounting walls; each mounting wall has a gap with the side wall of the receiving groove to accommodate a guardrail, and the gap between the two mounting walls is used to accommodate a first drive assembly; the mounting base is provided on the top of the mounting wall.

[0015] As described above, the lifting platform with automatic lifting guardrail and the slitting machine system of this utility model have at least the following beneficial effects: 1. High safety and convenient operation: By setting up a guardrail that can be raised and lowered independently of the operating platform, it can automatically rise to form a safety enclosure when the platform is raised, effectively preventing operators and tools from falling; when the platform is in a low position, the guardrail can be lowered to be level with or lower than the platform, forming an unobstructed open entrance, which greatly facilitates the entry and exit of operators and the delivery of tools, perfectly balancing safety and efficiency.

[0017] 3. Compact layout and high integration: For slitting machine systems, the main body of the lifting platform, drive components, and guardrails are cleverly housed underground through the design of receiving slots and mounting walls on the ground. This design not only saves ground space and avoids interference between the equipment and the platform during operation, but also ensures that the gaps and intervals between the mounting walls are rationally planned, allowing the guardrails and the first and second drive components to be integrated in an orderly and compact manner, resulting in a neat and aesthetically pleasing overall layout.

Detailed Implementation

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0024] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0025] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0026] Please see Figures 1-4 This utility model provides a lifting platform with an automatic lifting guardrail 4, comprising: a mounting base 1, an operating platform 2, a first lifting drive assembly 3, a guardrail 4, and a second lifting drive assembly 5. The mounting base 1 can be made of materials such as stainless steel and can be mounted on the bottom surface. The fixed end of the first lifting drive assembly 3 is mounted on the mounting base 1, and its output end is connected to the operating platform 2, used to drive the operating platform 2 to move up and down relative to the mounting base 1. The guardrail 4 is mounted on the operating platform 2, and the fixed end of the second lifting drive assembly 5 is mounted on the operating platform 2, and its output end is connected to the guardrail 4, used to drive the guardrail 4 to move up and down relative to the operating platform 2.

[0027] In use, the guardrail 4 of the lifting platform can be raised and lowered relative to the operating platform 2 under the drive of the second lifting component. This allows operators to quickly enter the operating platform 2 and easily transfer tools to it, improving operator efficiency. Then, the first lifting drive component 3 drives the operating platform 2 upward relative to the base, while the second lifting drive component 5 simultaneously drives the guardrail 4 upward to prevent operators or tools placed on the operating platform 2 from falling.

[0028] The first lifting drive assembly 3 includes a first drive component 31, multiple first guide sleeves 32 spaced apart on the mounting base 1, and multiple first guide rods 33 spaced apart below the operating platform 2.

[0029] The first driving component 31 can be a pneumatic cylinder or an electric cylinder. Its fixed end (e.g., cylinder body) can be fixed to the mounting base 1 by bolts or other fixing structures, and its output end (e.g., piston rod or push rod of an electric push rod) can be connected to the operating platform 2 by bolts or other fixing structures, specifically, it can be connected to the lower side of the operating platform 2. The first driving component 31 can be set on the lower side of the mounting base 1, and the mounting base 1 is provided with a first clearance hole for the piston rod or push rod of the first driving component 31 to pass through. The first guide sleeve 32 can also be set on the lower side of the mounting base 1 by bolts or other structures, and the mounting base 1 is provided with a second clearance hole for the first guide rod 33 to pass through. The first guide rod 33 can be fixed to the lower side of the operating platform 2 by bolts or other structures. Each first guide rod 33 corresponds to one first guide sleeve 32, and each guide rod can slide through the corresponding first guide sleeve 32, thereby providing stable guidance during the lifting and lowering of the operating platform 2 and preventing the operating platform 2 from swaying. When the operating platform 2 is raised to the required working height (designated position) under the drive of the first drive member 31, since the first drive member 31 is a cylinder or electric cylinder, it can reliably keep the operating platform 2 at the designated height by utilizing the self-locking effect of its own structure, without the need for additional mechanical locking devices, which simplifies the structure and ensures operational safety.

[0030] The mounting points of multiple first guide sleeves 32 on the mounting base 1 collectively define a polygonal region (e.g., a regular or irregular polygon such as a rectangle or triangle). The fixed end of the first drive member 31 is preferably located at the geometric center of this polygonal region. This centrally symmetrical layout ensures that the lifting drive force output by the first drive member 31 is evenly transmitted to the operating platform 2 through the guide pair formed by the multiple first guide sleeves 32 and the first guide rod 33. This effectively prevents the operating platform 2 from swaying or jamming during lifting, improving the stability and reliability of the movement.

[0031] Furthermore, the operating platform 2 is preferably rectangular. The fixed end of the first driving member 31 is located at the geometric center of the rectangular operating platform 2 (i.e., the intersection of the two diagonals). This arrangement coordinates the point of application of the driving force with the center of mass and the center of force of the operating platform 2, and works in conjunction with the aforementioned polygonal guide layout, further enhancing the overall anti-sway capability and motion stability of the operating platform 2 structurally.

[0032] In a preferred embodiment, there are four first guide sleeves 32. These four first guide sleeves 32 can be arranged at the four corners of the rectangular mounting base 1, and together with the first drive member 31 located in the center, they form a stable and symmetrical "center-driven-corner-guided" lifting support structure.

[0033] The second lifting drive assembly 5 includes at least one second drive component 51, multiple second guide sleeves 52 fixedly mounted on the operating platform 2, and multiple second guide rods 53 fixedly mounted at the bottom of the guardrail 4. The second drive component 51 is also a cylinder or electric cylinder. The fixed end of the second drive component 51 can be installed on the operating platform 2 via bolts or other structures, and its output end is rigidly connected to the guardrail 4 via bolts or other structures. Each second guide rod 53 corresponds to a second guide sleeve 52 and can slide within the second guide sleeve 52, thereby providing precise guidance and stable support for the lifting movement of the guardrail 4.

[0034] Preferably, the operating platform 2 is rectangular, and the guardrail 4 is a U-shaped frame structure matching the operating platform 2, including a front guardrail 41 and two connected side guardrails 42, which together enclose a safe operating space. In this preferred embodiment, the second lifting drive assembly 5 further includes two second drive members 51, four second guide sleeves 52, and four second guide rods 53. These components are symmetrically divided into two groups, each group corresponding to one side guardrail 42. Specifically, each group includes one second drive member 51, two second guide sleeves 52, and two second guide rods 53, and the second drive member 51 is located between the two second guide sleeves 52 in the same group. This "one drive, two guides" layout ensures that the driving force is applied at a reasonable position where the side guardrail 42 is subjected to force, and the synchronous driving on both sides ensures that the U-shaped guardrail 4 is subjected to balanced force and runs smoothly during lifting, effectively preventing asynchronous lifting or structural deformation.

[0035] On the other hand, a slitting machine system is also provided, including a slitting machine and a lifting platform with an automatic lifting guardrail 4 as described above.

[0036] A slitting machine is an aluminum processing device used to precisely longitudinally cut double-layer aluminum and aluminum alloy foil of a certain thickness, and to neatly roll up multiple strips of the cut material with ideal tension. Its specific structure and working principle are existing technologies, and will not be described in detail in this embodiment.

[0037] On the discharge side of the slitting machine, there is a receiving trough 6 on the ground to accommodate the entire lifting platform. The design of the receiving trough 6 allows the top of the lifting platform to be lowered to be level with or below the ground when not in use, thereby avoiding spatial interference with normal material transfer and equipment operation in the slitting machine area.

[0038] The receiving slot 6 is equipped with two parallel mounting walls 7 spaced apart. The mounting base 1 of the lifting platform is fixedly installed on the top of these two mounting walls 7. Sufficient clearance is reserved between each mounting wall 7 and the adjacent side wall of the receiving slot 6. This clearance is specifically designed to accommodate the guardrail 4 and the second lifting drive assembly 5 when the guardrail 4 is lowered, ensuring unobstructed lifting of the guardrail 4. The space between the two mounting walls 7 is used to accommodate and protect the first lifting drive assembly 3 (especially the first drive member 31 located at the center and the first guide sleeve 32 and the first guide rod 33 around it). This arrangement ensures the overall stable support of the lifting platform and achieves a compact and orderly integration of complex drive and protection structures within a limited space, ensuring a neat overall layout and no interference between functions.

[0039] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
