Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for textile machinery, and in particular to a simple safety guardrail based on a multi-compartment cotton blending machine. Background Technology

[0002] In yarn spinning, the multi-compartment blending machine is an important piece of equipment in the opening and cleaning process, mainly used for blending and opening fiber raw materials. Due to the large size and height of the multi-compartment blending machine, operators need to frequently climb up and down the equipment to perform safety inspections and maintenance.

[0003] In existing technologies, when the spacing of some guardrails needs to be adjusted, the locking block is pulled out of the slot, the number of locking units is increased or decreased as needed, or the relative position between the units is adjusted, and then the locking block is inserted into the slot to adjust the guardrail spacing.

[0004] However, in actual use, the lack of specialized climbing facilities and safety protection devices usually leads to higher safety risks for operators during work, such as slipping and falling. Therefore, designing a simple safety railing that integrates stairs, platforms and railings is of great significance for improving the safety and ease of operation of multi-bin cotton blending machine maintenance and inspection. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a simple safety guardrail for multi-compartment cotton blending machines, which solves the problem of the lack of safety protection facilities during safety inspections and maintenance of multi-compartment cotton blending machines in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A simple safety railing for a multi-compartment cotton blending machine includes a base, the top of which is fixedly connected to the multi-compartment cotton blending machine body. A platform is fixedly connected to the outside of the multi-compartment cotton blending machine body. A staircase is fixedly connected to the left side of the platform. Handrails are fixedly connected to the front and rear sides of the staircase. A slider is slidably connected inside the platform. A railing is fixedly connected to the top of the slider. An adjustable spacing mechanism is fixedly connected to the outside of the railing. A disassembly mechanism is fixedly connected to each of the four corners of the platform.

[0008] The adjustable spacing mechanism includes a fixed rod, a rotating plate rotatably connected to the outside of the fixed rod, a fixed shaft fixedly connected to the outside of the rotating plate, limit components fixedly connected to the front and rear sides of the fixed shaft, and the outside of the fixed rod fixedly connected to the inside of the railing.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting ring, the limiting ring being fixedly connected to the outside of the rotating plate, and the limiting ring being fixedly connected to the front and rear sides of the fixed shaft.

[0011] As a further description of the above technical solution:

[0012] The disassembly mechanism includes a mounting frame, a connecting shaft is fixedly connected inside the mounting frame, a rotating plate is rotatably connected to the outside of the connecting shaft, a telescopic rod is fixedly connected to the left and right sides of the outside of the rotating plate, a spring is sleeved on the outside of the telescopic rod, a clamping rod is fixedly connected to the other end of the rotating plate, and the mounting frame is fixedly connected to the four corners of the outside of the platform.

[0013] As a further description of the above technical solution:

[0014] A guide post is fixedly connected to the top of the railing, and a telescopic rod is slidably connected to the outside of the guide post.

[0015] As a further description of the above technical solution:

[0016] A limiting block is fixedly connected to the top of the railing, and the outside of the guide post is in contact with the outside of the limiting block;

[0017] As a further description of the above technical solution:

[0018] A pipe is fixedly connected to the bottom left side of the base, and the outside of the pipe is in contact with the outside of the platform;

[0019] As a further description of the above technical solution:

[0020] The platform has a groove at its outer top, and the slider is slidably connected to the inside of the groove.

[0021] As a further description of the above technical solution:

[0022] One end of the spring is fixedly connected to the outer bottom of the rotating plate, and the other end of the spring is fixedly connected to the outside of the platform.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pushing the railing, the railing slides inside the slide groove via a slider, which in turn causes the rotating plate outside the railing to rotate, causing the distance between the two railings to shrink. When the railing shrinks, the telescopic rod can shrink inside the guide post, thereby adjusting the distance between the two railings. When inspecting and maintaining a multi-bin cotton blending machine, railings with adjustable spacing may obstruct maintenance personnel from accessing certain parts of the equipment. Maintenance personnel may need to spend more time and effort to disassemble or bypass the railings, thus reducing maintenance efficiency.

[0025] 2. In this utility model, by pressing the rotating clamping plate, the rotating clamping plate can press the telescopic rod, which in turn causes the spring on the outside of the telescopic rod to deform, allowing the rotating clamping plate to separate from the outside of the railing through the clamping rod, thereby enabling the disassembly of the railing. When the equipment is running normally, the installed guardrail can provide a reliable physical barrier for operators and surrounding personnel, preventing personnel from accidentally touching operating parts and reducing the risk of accidents. In certain specific low-risk maintenance operations or short-term debugging phases, some or all of the guardrails can be removed as needed, which does not affect operation and improves the convenience of personnel movement, making safety protection more targeted and flexible.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a simple safety guardrail based on a multi-compartment cotton blending machine, including a base 1. The base 1 is the basic support structure of the entire simple safety guardrail based on the multi-compartment cotton blending machine, usually made of high-strength concrete or welded and assembled from large I-beams, channel steel, and other steel materials. It has a large volume and weight, the purpose of which is to provide stable support for the multi-compartment cotton blending machine body 2 and the entire guardrail. The multi-compartment cotton blending machine body 2 is fixedly connected to the top of the base 1. The multi-compartment cotton blending machine body 2 is the core component of the entire equipment, used to blend various different cotton raw materials to meet the needs of textile production. It consists of multiple blending compartments, conveying pipes 22, stirring devices, etc., and the various parts work together to achieve efficient cotton blending operations. A platform 5 is fixedly connected to the outside of the multi-compartment cotton blending machine body 2, providing operators with a convenient working area for operating and maintaining the multi-compartment cotton blending machine. Platform 5 is typically made of thick steel plate with a non-slip surface treatment, such as laying non-slip mats or stamping with patterns, to prevent operators from slipping while walking or working on it. A staircase 3 is fixedly connected to the outer left side of platform 5, serving as the passageway for operators to ascend and descend platform 5. Staircase 3 consists of stair treads and handrails 4. The stair treads are made of materials with good non-slip properties, such as steel plates with non-slip textures or non-slip rubber plates. The height and width of each tread are ergonomically designed for easy walking. Handrails 4 are fixedly connected to the outer front and rear sides of staircase 3, and are generally made of metal tubing, such as stainless steel tubing.

[0034] The height of the handrail 4 meets safety standards and is easy for operators to grip. Its surface is polished, smooth, and burr-free to avoid injury to operators. A slider 13 is slidably connected inside the platform 5. The slider 13 is a key component for adjusting the position of the guardrail 14. The slider 13 is made of high-strength metal materials, such as aluminum alloy or alloy steel, and its surface is precision-machined to fit tightly with the internal groove 12 of the platform 5, allowing it to slide smoothly within the groove 12. The top of the slider 13 is fixedly connected to the guardrail 14, which is the main protective structure of the simple safety railing, used to prevent operators from falling from the platform 5. The railing 14 is typically made of metal tubing, such as stainless steel or galvanized steel, and its height and spacing meet safety regulations. An adjustable spacing mechanism is fixedly connected to the outside of the railing 14. Disassembly mechanisms are fixedly connected to the four outer corners of the platform 5. These disassembly mechanisms include mounting frames 6, which are made of high-strength metal materials, such as steel plates, and are fixed to the four outer corners of the platform 5 by welding. A connecting shaft 7 is fixedly connected internally to the mounting frame 6. The connecting shaft 7 is generally made of alloy steel, possessing good strength and wear resistance. Both ends of the connecting shaft 7 are firmly fixed to the side walls of the mounting frame 6 to ensure its stability. A rotating clamping plate 8 is rotatably connected to the outside of the connecting shaft 7. The rotating clamping plate 8 is typically formed by stamping metal sheets and then surface hardening to enhance its wear resistance and strength. One end of the rotating clamping plate 8 is fitted onto the connecting shaft 7, allowing for flexible rotation via bearings. Telescopic rods 9 are fixedly connected to the left and right outer sides of the rotating clamping plate 8. The telescopic rods 9 are typically composed of multiple nested sections of high-strength metal tubing and have extendable characteristics. Its exterior is treated with a special wear-resistant material to reduce friction during the extension and retraction process. A spring 10 is sleeved on the outside of the telescopic rod 9. The spring 10 is the core elastic element of the elastic structure and is made of high-quality spring steel, which has good elasticity and fatigue life. One end of the spring 10 is tightly connected to the telescopic rod 9, and the other end is fixed to a specific position on the rotating plate 8 or the mounting bracket 6. The other end of the rotating plate 8 is fixedly connected to a locking rod 11. The locking rod 11 is made of a high-hardness metal material, such as tool steel, and its surface has undergone special hardening treatment to enhance wear resistance and deformation resistance. The mounting bracket 6 is externally fixedly connected to the four outer corners of the platform 5.

[0035] The adjustable spacing mechanism includes a fixed rod 18, which is made of high-strength alloy steel and undergoes precision forging and machining processes, resulting in excellent strength and stability. Its surface is polished, making it smooth and aesthetically pleasing, and also reducing friction during rotation. A rotating plate 20 is externally connected to the fixed rod 18. The rotating plate 20 is typically formed by stamping metal sheets, followed by heat treatment and surface hardening, significantly enhancing its wear resistance and strength. The shape of the rotating plate 20 is designed according to the adjustable spacing requirements and the overall structural layout. A fixed shaft 19 is externally fixed to the rotating plate 20. The fixed shaft 19 is made of a similar high-strength alloy steel as the fixed rod 18, providing good strength and rigidity.

[0036] Both ends of the fixed shaft 19 are firmly fixed to the outside of the rotating plate 20 by welding or special riveting process, ensuring that the fixed shaft 19 will not loosen or shift during the rotation of the rotating plate 20 and the operation of the limiting components. Limiting components are fixedly connected to the front and rear sides of the fixed shaft 19. The limiting components include limiting rings 21. The limiting rings 21 are made of high-hardness metal materials, such as tool steel, and are surface hardened to further improve their wear resistance and deformation resistance. The inner diameter of the limiting rings 21 is precisely matched with the outer diameter of the fixed shaft 19. They are tightly fixed to the front and rear sides of the fixed shaft 19 by interference fit or welding. The external of the limiting rings 21 is fixedly connected to the outside of the rotating plate 20. The external of the limiting rings 21 is fixedly connected to the front and rear sides of the fixed shaft 19. The external of the fixed rod 18 is fixedly connected to the inside of the railing 14.

[0037] Reference Figures 2 to 4 The top of the railing 14 is fixedly connected to a guide post 16, which is made of high-strength, high-toughness alloy steel, such as chromium-molybdenum alloy steel. This material not only has good mechanical properties, but also maintains structural stability under certain pressure and tension. The guide post 16 is slidably connected to a telescopic rod 17, which is usually composed of multiple nested metal tubes of different diameters. Each metal tube is made of high-quality aluminum alloy and is precision machined to ensure the fit between the sections. The top of the railing 14 is fixedly connected to a limit block 15, which is made of a high-hardness metal material, such as carbon steel, and is quenched to enhance its wear resistance and deformation resistance. The outside of the guide post 16 is in contact with the outside of the limit block 15. The bottom left side of the base 1 is fixedly connected to a pipe 22, which is made of corrosion-resistant and wear-resistant material.

[0038] The specific material of the pipe 22 is selected according to the medium transported in the pipe 22 and the usage environment. The outside of the pipe 22 is in contact with the outside of the platform 5. A groove 12 is provided at the top of the outside of the platform 5. The groove 12 is formed on the top of the platform 5 by precision machining process, such as milling and grinding. The shape of the groove 12 is usually rectangular. Its size is precisely designed according to the shape of the slider 13 to ensure that the slider 13 can slide smoothly in the groove 12 without loosening or shaking. The outside of the slider 13 is slidably connected to the inside of the groove 12. One end of the spring 10 is fixedly connected to the bottom of the rotating plate 8, and the other end of the spring 10 is fixedly connected to the outside of the platform 5.

[0039] Working principle: When adjusting the spacing of the railing 14, by pushing the railing 14, the railing 14 slides inside the slide groove 12 via the slider 13, which in turn causes the rotating plate 20 outside the railing 14 to rotate, causing the spacing between the two railings 14 to shrink. When the railing 14 shrinks, the telescopic rod 17 can retract inside the guide post 16, thereby realizing the adjustment of the spacing between the two railings 14.

[0040] When disassembling the railing 14, the rotating clamping plate 8 is pressed, causing it to press the telescopic rod 9. This causes the spring 10 on the outside of the telescopic rod 9 to deform, allowing the rotating clamping plate 8 to separate from the outside of the railing 14 via the clamping rod 11. This enables the disassembly of the railing 14. When installing the railing 14, it is placed inside the slide groove 12. By releasing the rotating clamping plate 8, the spring 10 rebounds, allowing the rotating clamping plate 8 to clamp the railing 14 via the clamping rod 11. This enables the installation of the railing 14.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
