Description

Technical Field

[0001] This invention relates to the field of oxidant storage technology. More specifically, this invention relates to a field-mixed emulsion matrix storage and pumping device. Background Technology

[0002] The emulsified matrix mixed on-site, acting as an oxidant, is highly corrosive. Currently, most mine surface stations use stainless steel storage tanks for this purpose. While stainless steel is corrosion-resistant, its high manufacturing cost significantly increases investment in surface station facilities. The matrix's initial viscosity ranges from 30,000 to 120,000 centipoise, and during storage, aging and crystallization cause the viscosity to rise continuously, leading to a sharp increase in pumping system pressure. When the pumping pressure exceeds the equipment's pressure limit, it can easily cause pipeline rupture or pump damage, posing a safety and environmental hazard.

[0003] Furthermore, storage tank outlet pipelines typically only have a single valve. If this valve leaks or fails, the high-viscosity matrix is ​​difficult to seal quickly, easily causing continuous environmental pollution. Due to the high corrosiveness and time-varying viscosity of the matrix, achieving safe storage and reliable pumping while controlling costs presents a technical contradiction: reducing equipment costs while meeting overpressure protection and multiple leak prevention requirements poses a dual challenge to material selection and system design. Utility Model Content

[0004] One objective of this invention is to provide a field-mixed emulsified matrix storage and pumping device, comprising:

[0005] The plastic cone-shaped container has a breather valve at the top and a flange fixedly connected to the bottom. The outside of the plastic cone-shaped container is equipped with a liquid level measuring structure.

[0006] The bracket, which provides fixed support for the plastic cone-shaped barrel, is equipped with a protective cage ladder;

[0007] The outlet vertical pipe is vertically connected to a flange at one end, and horizontally connected to an outlet horizontal pipe at the other end. The outlet horizontal pipe is equipped with a ball valve at the other end, and the outlet vertical pipe is equipped with a butterfly valve.

[0008] The gear pump has its inlet end connected to the outlet of a ball valve via a pipe, and its outlet end is connected to a rubber hose.

[0009] A safety valve is located at the pressure relief port of the gear pump body.

[0010] Preferably, the distance between the butterfly valve and the flange is 30~50cm.

[0011] Preferably, the opening pressure range of the safety valve is 0.9~1.0MPa.

[0012] Preferably, the pressure relief outlet of the safety valve is connected to a return pipe, and the other end of the return pipe extends to a range of 10-20cm to the side of the breather valve at the top of the plastic cone.

[0013] Preferably, the side wall of the plastic cone is provided with annular reinforcing ribs, with the spacing between the reinforcing ribs being 50~80cm.

[0014] Preferably, the annular reinforcing rib extends to the flange connection at the bottom of the plastic cone barrel, forming a conical transition section with an inclination angle of 15~30°.

[0015] Preferably, the valve seat sealing surface of the butterfly valve and ball valve is covered with a polytetrafluoroethylene (PTFE) layer with a thickness of 1-2 mm.

[0016] Preferably, the liquid level measuring structure is a magnetic float level gauge, and the float density of the magnetic float level gauge is less than the density of the emulsion matrix.

[0017] Preferably, the step spacing of the cage ladder is 250~300mm, and the surface of the steps of the cage ladder is provided with anti-slip texture, the depth of the anti-slip texture is 1.5~2.5mm, and the texture spacing is 10~15mm.

[0018] This utility model has at least the following beneficial effects:

[0019] First, this utility model addresses the issue of high cost of stainless steel storage tanks by using plastic conical tanks as the main storage unit. The cost of plastic conical tanks made of polyethylene or polypropylene is significantly lower than that of stainless steel, and they are also corrosion-resistant. While meeting storage requirements, this effectively reduces the equipment investment cost of mine surface stations.

[0020] Secondly, this utility model addresses the risk of overpressure during the pumping of high-viscosity emulsion matrices by installing a safety valve with an opening pressure of 0.9~1.0MPa at the pressure relief port of the gear pump. When the pumping pressure exceeds the threshold, the valve automatically releases pressure, preventing damage to the pump body and pipelines due to overpressure, reducing the possibility of safety and environmental accidents, and ensuring the stability of the pumping process.

[0021] Third, this utility model addresses the leakage risks of traditional single-valve structures by installing butterfly valves and ball valves in the vertical and horizontal outlet pipes respectively, forming a double shut-off structure. The distance between the butterfly valve and the flange is controlled at 30~50cm, which facilitates operation. The dual-valve design can avoid media leakage caused by the failure of a single valve. Combined with the polytetrafluoroethylene layer on the valve seat sealing surface, the sealing performance is further improved, and the risk of environmental pollution is reduced.

[0028] like Figure 1 As shown, this utility model provides a field-mixed emulsion matrix storage and pumping device, comprising:

[0029] The plastic cone tank 1 has a breather valve 14 at the top and a flange 2 fixedly connected to the bottom. The outside of the plastic cone tank 1 is equipped with a liquid level measuring structure 13. Specifically, the plastic cone tank 1 can be made of corrosion-resistant plastic materials such as polyethylene or polypropylene, which can withstand the corrosiveness of the mixed emulsion matrix on site. The breather valve 14 is installed at the center of the top of the plastic cone tank 1 to balance the air pressure inside the tank. The flange 2 is fixed to the center of the bottom of the plastic cone tank 1 and is bolted to ensure a seal. The liquid level measuring structure 13 can be a magnetic float liquid level gauge or an ultrasonic liquid level gauge, which is installed on the outer wall of the plastic cone tank 1 to facilitate real-time observation of the internal liquid level. The mixed emulsion matrix on site is stored in the plastic cone tank 1. The breather valve 14 automatically adjusts the air pressure inside the tank to prevent pressure changes from affecting storage safety. The liquid level measuring structure 13 continuously monitors the liquid level. When pumping is required, the matrix enters the outlet pipeline system through the bottom flange 2. The corrosion resistance of the plastic material replaces the traditional stainless steel storage tank, reducing equipment costs. At the same time, the lightweight structure facilitates installation and movement.

[0030] The support frame 11 provides a fixed support for the plastic cone 1 and is equipped with a protective cage ladder 12. Specifically, the support frame 11 can be welded from Q235 carbon steel and fixed to the ground at the bottom with anchor bolts to ensure stable support. The protective cage ladder 12 is installed on the side of the support frame 11, and the ladder steps are made of anti-slip steel plates. The height of the protective cage railings meets safety standards to ensure the safety of personnel climbing. The assembly position of the support frame 11 needs to be designed according to the size of the plastic cone 1 to ensure that the center of gravity of the plastic cone 1 is vertically aligned with the support point of the support frame 11 to avoid uneven force. When it is necessary to inspect or repair the plastic cone 1, personnel can climb to the top of the plastic cone 1 through the protective cage ladder 12 to observe the status of components such as the breather valve 14 through the liquid level measuring structure 13 or directly. The support frame 11 provides stable support for the plastic cone 1, and the protective cage ladder 12 meets the safety maintenance requirements and facilitates daily inspection and maintenance work by operators.

[0031] The outlet vertical pipe 4 is vertically connected to the flange 2 at one end, and horizontally connected to the outlet horizontal pipe 5 at the other end. The outlet horizontal pipe 5 is equipped with a ball valve 6 at the other end, and the outlet vertical pipe 4 is equipped with a butterfly valve 3. Specifically, the distance between the outlet vertical pipe 4 and the flange 2 is controlled within the range of 30cm to 50cm to ensure that the butterfly valve 3 is easy to operate. The pipe material can be stainless steel or fluoroplastic lined pipe to resist the corrosion of the emulsion matrix. Both butterfly valve 3 and ball valve 6 are corrosion-resistant valves, such as PTFE-lined butterfly valve 3 and all-plastic ball valve 6, to ensure sealing performance. The outlet vertical pipe 4 is vertically welded above flange 2. Butterfly valve 3 is installed in the middle of the vertical pipe, 230-50cm away from the flange. The outlet horizontal pipe 5 is horizontally connected to the vertical pipe through an elbow. Ball valve 6 is installed at the end of the horizontal pipe. When butterfly valve 3 and ball valve 6 are opened, the emulsion matrix in the plastic cone 1 can fill the outlet vertical pipe 4 and outlet horizontal pipe 5 by gravity in the initial low viscosity state. When the viscosity of the medium increases or it needs to be transported to the mixing truck 10, the gear pump 8 is started to provide the conveying power. After pumping is completed, ball valve 6 is closed first, and then butterfly valve 3 is closed to form a double shut-off. This avoids matrix leakage due to the failure of a single valve. This double valve design improves the reliability of pipeline shut-off, reduces the risk of leakage, and ensures the safety of storage and pumping processes.

[0032] The gear pump 8 has its inlet end connected to the outlet of the ball valve 6 via a pipe, and the outlet end of the gear pump 8 is connected to a rubber hose 7.

[0033] Safety valve 9 is located at the pressure relief port of gear pump 8. Specifically, the opening pressure range of safety valve 9 is 0.9 MPa to 1.0 MPa, which can be adjusted according to the actual pumping pressure requirements. Stainless steel gear pump 8 can be selected to adapt to the high viscosity of the emulsion matrix. Rubber hose 7 is made of oil- and corrosion-resistant nitrile rubber or fluororubber to ensure no leakage during transportation. Safety valve 9 is installed at the pressure relief port of gear pump 8 and fixed by threaded connection. Both ends of rubber hose 7 are connected to the outlet of gear pump 8 and the inlet of mixing truck 10 respectively through flange 2. During operation, the emulsified matrix is ​​first filled into the inlet of gear pump 8 under gravity. After gear pump 8 starts, it actively pressurizes to overcome the high viscosity resistance (up to 120,000 centipoise) and delivers the matrix to the mixing truck 10 through rubber hose 7. When the pumping pressure exceeds the opening pressure of safety valve 9 (0.9-1.0 MPa), safety valve 9 automatically opens to release pressure, protecting gear pump 8 and pipeline from overpressure damage. Through the pressure relief protection of safety valve 9, the occurrence of overpressure is reduced, the safety of the pumping process is improved, and the possibility of equipment damage and safety and environmental accidents is reduced.

[0034] In another technical solution, the distance between butterfly valve 3 and flange 2 is 30~50cm. Specifically, butterfly valve 3 can be a fluoropolymer-lined butterfly valve, whose sealing surface is lined with fluoroplastic, which can withstand the corrosiveness of the mixed emulsion matrix on site. Flange 2 can be a necked weld neck flange 2, made of stainless steel 304 or 316, to ensure the connection strength and sealing performance with the bottom of the plastic cone 1. The two are fixed by bolts, and the bolt material can be 304 stainless steel to prevent rust from affecting disassembly. Controlling the distance between butterfly valve 3 and flange 2 at 30cm to 50cm ensures that the installation position of butterfly valve 3 is convenient for operators to operate directly without the need for climbing tools, which improves the convenience of daily operation. At the same time, the reasonable distance avoids stress concentration caused by excessively long or short pipelines, ensures the stability of the sealing performance of butterfly valve 3, thereby improving the reliability of the outlet vertical pipeline 4 cutoff, reducing the risk of emulsion matrix leakage caused by improper valve installation position, and enhancing the safety of the entire storage and pumping device.

[0035] In another technical solution, the opening pressure range of safety valve 9 is 0.9~1.0 MPa; specifically, the opening pressure range of safety valve 9 is set to 0.9 MPa to 1.0 MPa. This value range is selected based on the characteristics of the mixed emulsion matrix on site. Since the viscosity of the emulsion matrix is ​​usually between 30,000 and 120,000 livots, and the viscosity further increases after storage and aging, the pressure will increase significantly during pumping. Therefore, setting the opening pressure of safety valve 9 at 0.9~1.0 MPa can meet the pressure required for normal pumping and also provide timely pressure relief in case of overpressure. Safety valve 9 can be a spring-loaded safety valve. This type of valve controls the opening pressure through spring preload, has a simple structure, is easy to adjust on site, and can adapt to the pumping environment of the emulsion matrix. In this system, when gear pump 8 pumps the emulsified matrix, if the pressure in the pipeline exceeds the 0.9~1.0MPa range set by safety valve 9 due to factors such as increased matrix viscosity or valve closure, the valve core of safety valve 9 will automatically open to overcome the spring preload, returning excess medium to the pump inlet or safety container, thereby reducing system pressure. When the pressure drops below the set value, the valve core will automatically close under spring force, restoring normal pumping. By precisely controlling the opening pressure of safety valve 9, problems such as damage to gear pump 8 and pipeline rupture caused by excessive pressure during pumping are effectively avoided, reducing the possibility of safety and environmental accidents. At the same time, it ensures stable delivery of the emulsified matrix within the normal pressure range, improving the safety and reliability of the storage and pumping devices.

[0036] In another technical solution, the pressure relief outlet of safety valve 9 is connected to a return pipe, and the other end of the return pipe extends to a range of 10-20cm to the side of the breather valve 14 at the top of the plastic cone 1. Specifically, the length of the return pipe can be adjusted according to actual installation requirements. For example, when the horizontal distance between the breather valve 14 at the top of the plastic cone 1 and safety valve 9 is 1.5m, the pipe length can be designed to be 1.6-1.7m to ensure that the end is within the specified range. The return pipe can be made of seamless steel pipe of 304 stainless steel or corrosion-resistant PVC plastic pipe, which can withstand the corrosion of the emulsion matrix and has sufficient strength to withstand pumping pressure. One end is fixedly connected to the pressure relief outlet of safety valve 9 through flange 2 or thread, and the other end extends to the top of plastic cone 1, with its end opening located within a range of 10-20cm to the side of breather valve 14. During installation, first measure the specific position of breather valve 14 at the top of plastic cone 1, and take the center of breather valve 14 as a reference, within a radius of 10-20cm... Within a circular area of ​​cm, the end position of the return pipe is determined to ensure that the outlet does not directly face the inlet of the breather valve 14, thus preventing the medium from impacting the internal structure of the breather valve 14 during depressurization. The pipe route must be fixed along the outside of the support 11 or the wall of the plastic cone 1 to avoid vibration caused by suspension. When the pumping pressure of the gear pump 8 exceeds the opening pressure of the safety valve 9, the safety valve 9 opens to depressurize, and the emulsified matrix flows back into the plastic cone 1 through the return pipe. Since the end of the return pipe is located 10-20cm to the side of the breather valve 14, the medium will flow down along the inner wall of the plastic cone 1 during return, avoiding direct impact on the breather valve 14 and causing damage to the valve body. At the same time, the breather valve 14 balances the air pressure inside the plastic cone 1, allowing the depressurized medium to be safely recovered into the storage container, reducing medium waste and environmental pollution risks. It also avoids pressure fluctuations caused by improper pipe connections during depressurization, further improving the safety and stability of the pumping system and ensuring that the device can effectively protect the equipment and maintain normal system operation under overpressure conditions.

[0037] In another technical solution, the sidewall of the plastic cone 1 is provided with annular reinforcing ribs, with a spacing of 50-80cm. Specifically, the spacing range is set based on the height and stress distribution of the plastic cone 1. For example, when the height of the plastic cone 1 is 3m, 4-6 reinforcing ribs can be set, with a spacing of 55cm, 60cm, or 70cm, etc., to evenly distribute the internal pressure and external load borne by the sidewall. The annular reinforcing ribs can be made of polyethylene or polypropylene profiles of the same material as the plastic cone 1 to ensure material compatibility and facilitate fixing to the sidewall of the plastic cone 1 by hot-melt welding or bolt connection. The assembly position of the annular reinforcing ribs needs to be evenly distributed along the circumference of the sidewall of the plastic cone 1, with the center line of each reinforcing rib perpendicular to the axis of the plastic cone 1, forming a complete annular structure. During installation, first mark horizontal lines with a spacing of 50-80cm on the sidewall of the plastic cone 1, and then fix the reinforcing ribs along the marked lines to ensure that the reinforcing ribs are tightly fitted to the wall of the plastic cone 1. The plastic cone tank 1 can have support blocks added inside the reinforcing ribs to enhance the connection strength. The cross-sectional shape of the reinforcing ribs can be rectangular or semi-circular, and the cross-sectional dimensions are determined according to the diameter of the plastic cone tank 1 and the weight of the stored medium. When the plastic cone tank 1 stores mixed emulsion matrix on site, the weight and static pressure of the internal medium will exert outward pressure on the sidewall. The annular reinforcing ribs constrain the deformation of the sidewall through their own structural strength, distributing the pressure throughout the entire structure of the plastic cone tank 1. Since the spacing of the reinforcing ribs is controlled at 50~80cm, it can effectively prevent the sidewall from bulging or cracking due to local stress concentration. During the pumping process, when the internal pressure of the plastic cone tank 1 fluctuates, the reinforcing ribs can also maintain the stability of the sidewall, avoiding the impact of structural deformation on the accuracy of the liquid level measuring device. Through the supporting effect of the annular reinforcing ribs, the overall structural strength of the plastic cone tank 1 is enhanced, making it stable when storing and pumping emulsion matrix, extending the service life of the device, and reducing the risk of medium leakage due to deformation of the plastic cone tank 1.

[0038] In another technical solution, the annular reinforcing rib extends to the flange 2 connection at the bottom of the plastic cone 1, forming a conical transition section with an inclination angle of 15~30°. Specifically, the 15~30° angle range is set based on the stress distribution characteristics at the flange 2 connection. For example, when the inclination angle is less than 15°, the support effect of the transition section is not obvious; if it exceeds 30°, it may affect the flow of the medium at the bottom of the plastic cone 1. In practical applications, the angle can be precisely adjusted according to the diameter of the plastic cone 1 and the size of the flange 2 to balance the structural strength and the flow of the medium. The annular reinforcing rib and the conical transition section can be made of the same polyethylene or polypropylene material as the plastic cone 1, and formed into an integrated structure through hot-melt welding to ensure material compatibility and connection strength. The assembly position of the conical transition section needs to extend downward from the annular reinforcing rib on the side wall of the plastic cone 1 to the edge of the bottom flange 2, forming a smooth transition from the body to the flange 2. During installation, the start and end positions of the transition section are marked at the connection between the side wall of the plastic cone 1 and the flange 2, and then the prefabricated conical... The transition section plate is fixed along the marked line, ensuring that the inclination angle of the transition section is within the range of 15° to 30°. The inner surface of the transition section needs to be polished smooth to avoid deposition due to obstruction of medium flow. For plastic cone 1 with a larger diameter, triangular support ribs can be added inside the transition section to further enhance the structural rigidity of the flange 2 connection. When the plastic cone 1 is used to store mixed emulsion matrix at the site, the weight and static pressure of the medium will generate concentrated stress at the flange 2 connection. The conical transition section, with its 15-30° inclination structure, evenly distributes the pressure borne by the side wall to the flange 2 area, avoiding connection failure caused by excessive local stress. During pumping, the impact force generated by the matrix flow is buffered by the conical structure of the transition section, reducing the impact on the sealing surface of the flange 2. This allows the annular reinforcing ribs and flange 2 to form a continuous support system, enhancing the structural strength of the bottom of the plastic cone 1 and effectively preventing cracks or leaks at the flange 2 connection due to stress concentration. At the same time, it ensures the smooth flow of the emulsion matrix in the plastic cone 1, improving the overall reliability and service life of the storage and pumping device.

[0039] In another technical solution, the valve seat sealing surfaces of butterfly valve 3 and ball valve 6 are covered with a polytetrafluoroethylene (PTFE) layer with a thickness of 1-2 mm. Specifically, the thickness range is set based on the balance between sealing performance and material durability. In practical applications, the thickness can be precisely adjusted according to the valve specifications to adapt to valves with different flow diameters. The PTFE layer can be attached to the valve seat sealing surface through molding or spraying. This material has excellent corrosion resistance and can resist the erosion of mixed emulsions in the field. The PTFE layer on the valve seat sealing surface covers the sealing contact area of ​​butterfly valve 3 and ball valve 6, that is, the annular surface where the valve disc and valve seat fit when the valve is closed. During assembly, the metal substrate of the valve seat is first sandblasted to enhance adhesion, and then the PTFE layer is fixed by hot melt sintering or bonding process to ensure uniform layer thickness and no air bubbles. For butterfly valve 3, the PTFE layer usually covers the circumferential sealing surface of the valve seat. For ball valve 6, it covers the contact ring between the ball and the valve seat, so that the sealing surface can withstand the scouring and friction of the medium during the opening and closing of the valve, while maintaining good sealing performance. When butterfly valve 3 or ball valve 6 is closed, the valve disc or ball squeezes the PTFE layer, causing it to elastically deform and fill the sealing gap, preventing leakage of mixed emulsions in the field. Because the thickness of the PTFE layer is controlled at 1~2mm, it can ensure sufficient elastic compensation capacity without causing excessive valve opening and closing resistance due to excessive thickness. In long-term use, the corrosion resistance of PTFE can prevent the sealing surface from being corroded by the emulsion matrix, thus extending the service life of the valve. Through the sealing and corrosion resistance characteristics of the PTFE layer, the sealing reliability of the valve is improved, reducing the risk of media waste and environmental pollution caused by valve leakage, and further enhancing the safety and stability of storage and pumping devices.

[0040] In another technical solution, the liquid level measuring structure 13 is a magnetic float level gauge, and the float density of the magnetic float level gauge is less than the density of the emulsion matrix. Specifically, the liquid level measuring structure 13 adopts a magnetic float level gauge, which can be an integrated structure with remote transmission function, consisting of a measuring cylinder, a float, and a magnetic float indicator. The measuring cylinder of the magnetic float level gauge can be made of stainless steel 304 or polyvinyl chloride to ensure resistance to the corrosiveness of the mixed emulsion matrix on site. The float density needs to be less than the density of the emulsion matrix, since the density of the emulsion matrix is ​​usually around 1. The float, with a density of approximately 0.3~1.5 g / cm³, can be made of engineering plastics (such as polypropylene) or stainless steel with a hollow structure. The density is controlled to 1.0~1.2 g / cm³ by filling with low-density materials (such as foam), ensuring the float can stably float on the medium surface. The magnetic level gauge is assembled on the outer wall of the plastic cone 1. The measuring cylinder is perpendicularly connected to the side wall of the plastic cone 1 via flange 2 or clamps, ensuring that the axis of the measuring cylinder is parallel to the axis of the plastic cone 1. During installation, the bottom of the measuring cylinder should maintain a 5-degree angle with the bottom flange 2 of the plastic cone 1. A distance of approximately 10cm is maintained to prevent bottom-deposited crystals from affecting the float's movement. The magnetic float indicator is installed on the outside of the measuring cylinder and, through magnetic coupling, rises and falls with the float to display the liquid level. The top of the level gauge maintains a safe distance from the breather valve 14 at the top of the plastic cone 1 to prevent interference with the top structure. When the plastic cone 1 stores mixed emulsion matrix, the float floats on the liquid surface because its density is less than that of the medium. It moves up and down within the measuring cylinder with the rise and fall of the liquid level. The permanent magnet inside the float drives the magnetic float outside the measuring cylinder to flip through magnetic field coupling, turning the white float red (or other contrasting color) to visually display the liquid level position. Because the float density is precisely controlled within a range less than that of the emulsion matrix, even if the medium viscosity rises to 120,000 livres or aging and crystallizing occurs, the float can still overcome the viscous resistance and float normally, ensuring the accuracy of the liquid level measurement. Utilizing the intuitive display and corrosion resistance of the magnetic float level gauge, reliable monitoring of the emulsion matrix liquid level is achieved, avoiding pumping abnormalities caused by misjudgment of the liquid level, and providing stable liquid level data support for the storage and pumping process.

[0041] In another technical solution, the step spacing of the cage ladder 12 is 250-300mm. The surface of the steps of the cage ladder 12 is provided with anti-slip texture, the depth of which is 1.5-2.5mm and the spacing between the textures is 10-15mm. Specifically, the step spacing of the cage ladder 12 is 250mm to 300mm. This spacing range conforms to ergonomic design, facilitating comfortable strides for operators during climbing and accommodating the climbing habits of people of different heights. The step plates can be made of 4-5mm thick Q235 carbon steel anti-slip steel plates with galvanized surface treatment to enhance corrosion resistance, or aluminum alloy step plates can be selected to reduce the overall weight. The surface of the steps of the cage ladder 12 is provided with anti-slip texture, the depth of which is 1.5mm to 2.5mm and the spacing between the textures is 10mm to 15mm. The anti-slip texture can be formed by stamping the surface of the step plate with raised and recessed strips, or by attaching rubber anti-slip strips or spraying anti-slip coating. The coating has a textured surface perpendicular to the length of the steps to enhance friction during stepping and ensure effective anti-slip performance even in wet conditions or with residual media. In addition to carbon steel, the step plates can be made of cast iron or stainless steel with natural anti-slip textures to further improve wear resistance. The cage ladder 12 is installed on the side of the support 11, arranged vertically along its height. The step spacing is evenly distributed from bottom to top, ensuring that the levelness error of each step does not exceed 5mm. During installation, the support frame of the cage ladder 12 is first fixed to the uprights of the support 11, and then the step plates are installed one by one, secured with bolts or welding to ensure a tight connection between the step plates and the support frame. When operators climb the cage ladder 12, the anti-slip texture on the step plates creates frictional resistance against the soles of their shoes, preventing slipping. The 250-300mm step spacing keeps the climber's leg joints naturally bent, reducing climbing fatigue.
