Description

Technical Field

[0001] This utility model relates to a maintenance device for a food spray drying tower, and more particularly to a modular novel umbrella-shaped tower body maintenance platform. Background Technology

[0002] Food spray drying towers are key pieces of equipment widely used in the food industry. Their tower bodies (including straight and conical sections) require regular inspection, cleaning, and maintenance after long-term operation. Currently, the traditional method commonly used in the industry for maintenance work inside such large towers is to erect temporary scaffolding. This traditional method requires workers to manually build scaffolding members and platforms layer by layer from the bottom of the tower in a high-altitude environment. This process is extremely time-consuming (usually several days) and requires a large number of people working together, resulting in high overall construction costs. Furthermore, during construction and use, workers are exposed to a high-altitude working environment for extended periods, facing a significant risk of fall. The stability of the scaffolding itself is difficult to guarantee in the complex tower environment (especially the conical section), further increasing safety hazards during maintenance work. Blind spots and operational inconvenience also exist; the dense scaffolding members create blind spots, obstructing workers' vision and affecting the comprehensive observation of the tower wall condition and the accuracy of maintenance operations.

[0003] Furthermore, existing food drying towers typically have significant variations in height and diameter (especially the conical section, where the diameter gradually decreases from top to bottom). Traditional scaffolding structures are fixed and cannot flexibly adapt to the diameter variations of different tower height sections, making it particularly difficult to build stable and size-matched working platforms in the conical section. Moreover, to ensure safety, the construction of high-altitude scaffolding usually requires the use of brand-new steel pipes and other materials. Old materials are often discarded due to potential hazards such as rust and deformation, resulting in significant material waste and increased costs, while also making the overall structure bulky. In addition, the scaffolding currently erected is designed for specific locations on specific towers, and after dismantling, it is difficult to quickly and conveniently apply it to other towers or different parts of the same tower, resulting in poor reusability and the inability to form standardized operating tools.

[0028] (6) The modules of the new umbrella-shaped tower maintenance platform are tightly connected.

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0045] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0046] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in order to solve the technical problems of low efficiency, poor safety, inability to flexibly adapt to different tower structures and poor reusability of traditional tower maintenance scaffolding, a new type of modular umbrella-shaped tower maintenance platform that can provide a stable working plane is provided. The maintenance platform mainly includes a support wheel 100, a central tie column 200, several sets of telescopic frames 300, platform treads 400 and side tie columns 500, as well as several support lugs 600 installed on the corresponding platform treads 400. Through these modular structures, the tower maintenance platform can be quickly assembled and adapted to different sizes.

[0047] Specifically, a support wheel 100 is provided on the top of the support wheel 100. The support wheel 100 serves as the central support node, and several retractable frames 300 are arranged at equal intervals on its outer periphery in an umbrella shape to form an umbrella-shaped unfolding mechanism. The length of the frames can be adjusted to adapt to changes in the diameter of the tower.

[0048] Platform treads 400 are laid side-by-side on adjacent retractable frames 300, forming a working plane by arranging the platform treads 400 side-by-side between adjacent retractable frames 300. Each retractable frame 300 has an upward-facing side support column 500 at its outer end, forming an external support point. Together with the platform treads 400, the three form a stable triangular load-bearing system.

[0049] Several support lugs 600 installed on the platform tread 400 provide external hoisting connection points for the maintenance platform, forming a multi-point hoisting system with the central support lugs 202 at the top of the central support column 200, so that the platform as a whole has the characteristic of being liftable.

[0050] In this modular new umbrella-shaped tower maintenance platform, based on the support wheel 100 and the central pull column 200, the modularly designed telescopic frame 300 and the assembled platform pedal 400, together with the corresponding pin connection method, can realize quick disassembly and replacement, and can also adjust the platform unfolding diameter according to the size requirements of different height sections of the tower's conical section.

[0051] In some of these embodiments, such as Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, the supporting wheel 100 consists of two sets of semi-circular supporting wheels 110 and a middle plate 120. By decomposing the supporting wheel 100 into the splicable semi-circular supporting wheels 110 and the middle plate 120, a modular and adjustable umbrella-shaped support structure is constructed. The arc design on the outer side of the semi-circular supporting wheels 110 allows for the even distribution of the retractable frame 300 around its outer perimeter, forming an umbrella-shaped unfolding mechanical support system. This creates a topological structure adaptable to different tower cross-sections for the subsequent laying of the platform treads 400. Preferably, as... Figure 7 As shown, the two intermediate plates 120 and the two semi-circular support wheels 110 at the bottom are arranged in a cross shape and are locked together by bolt assembly, which effectively ensures the structural stability of the support wheel 100.

[0052] Specifically, the two semi-circular support wheels 110 are symmetrically arranged and bolted together to form a circular wheel-like structure. A retractable frame 300 and modular platform treads 400 arranged in a ring can be built on the outer periphery of this circular wheel-like structure, ensuring the platform's structural stability while meeting the technical requirement of rapid assembly. The bolted connection method allows the semi-circular support wheels 110 to be transported separately and easily assembled on-site, overcoming the problems of traditional integral structures being bulky and difficult to disassemble.

[0053] Two symmetrically arranged intermediate plates 120 are laid on top of the two semi-circular support wheels 110, forming a complete circular support surface. It is worth noting that, as... Figure 9 As shown, the semi-circular support wheel 110 adopts a hollow frame structure, which is made of aluminum alloy in one piece. The structure is stable and provides a stable installation foundation for the maintenance platform. In addition, its light weight reduces material costs and facilitates transportation and installation.

[0054] In some of these embodiments, such as Figure 7 , Figure 8 and Figure 9 As shown, to ensure a reliable connection between the supporting wheel 100 and the retractable frame 300, several side plates 111 are sequentially arranged on the outer peripheral wall of the semicircular supporting wheel 110. These side plates 111 form evenly distributed support nodes, providing a precise positioning reference for the subsequent insertion of the retractable frame 300. Furthermore, the arrangement of the side plates 111 along the outer periphery of the supporting wheel 100 effectively disperses external loads and avoids stress concentration.

[0055] Meanwhile, to ensure a reliable connection between the supporting wheel 100 and the central support column 200, a semi-circular first flange 114 is fixedly installed at the dot position of the supporting wheel 100, so as to achieve quick docking between the first flange 114 and the second flange 201 at the bottom of the central support column 200, ensuring the coaxial connection accuracy between the supporting wheel 100 and the central support column 200, thereby forming a stable core support point for the umbrella-shaped unfolding mechanism.

[0056] As one of the preferred embodiments, such as Figure 7 , Figure 8 and Figure 9 As shown, in order to achieve a stable connection between the supporting wheel 100 and each retractable frame 300, a three-point positioning structure with an inverted triangle distribution is used. Three first side shafts 112 arranged in an inverted triangle are set on the side plate 111 to form a stable mechanical support foundation. The inverted triangle layout makes the force distribution more uniform and effectively avoids stress concentration at a single point.

[0057] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, to address the issue of stable connection between the tower maintenance platform and the supporting structure during vertical movement, a second flange 201 is installed at the bottom of the central support column 200, which mates with the two first flanges 114 on the top of the supporting wheel 100. The second flange 201 and the two first flanges 114 on the supporting wheel 100 form a complementary mechanical connection.

[0058] A central lifting lug 202 is installed at the top of the central support column 200. This lug serves as the main load-bearing point and connects directly to external lifting equipment such as an electric hoist, forming the force center for the overall lifting of the platform. The central lifting lug 202, the first flange 114, and the fixing ring 203 are all made of aluminum alloy and are welded integrally to the column body of the central support column 200, ensuring a stable structure and safety during hoisting. In use, the platform can be moved up and down by using the central lifting lug 202 at the top of the central support column 200 in conjunction with the external electric hoist.

[0059] Meanwhile, in order to meet the multi-point safety fixation requirements when the maintenance platform is raised and lowered, a number of fixed rings 203 arranged vertically at intervals can be set at the upper end of the central support column 200 according to actual application requirements. The fixed rings 203 are located below the central lifting lugs 202. The fixed rings 203 can serve as the connection position of the auxiliary lifting point, and can also fix the safety rope or limit device in layers, thereby improving the anti-overturning ability during high-altitude operations by distributing the load at multiple points.

[0060] In some of these embodiments, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, to address the problem of traditional scaffolding structures being fixed and unable to flexibly adapt to changes in the cross-sectional diameter of the tower at different heights, a specific modular, extendable frame structure 300 is adopted. This structure is composed of several triangular supports 310 of varying lengths, sequentially spliced ​​together, with adjacent triangular supports 310 connected by a second pin 311. By using modular splicing of triangular supports 310 of different lengths, the length of the frame is adjustable. Simultaneously, the mechanical connection of adjacent triangular supports 310 via the second pin 311 ensures the structural strength of the splicing nodes while simplifying the assembly process.

[0061] The structure employs a modular design that combines triangular supports of varying lengths (310) to form a retractable frame (300). This allows for flexible assembly of platform support bases of different diameters to match the gradually decreasing diameter of the tower's tapered section. The pin-connection method eliminates the cumbersome processes of welding or bolting, improving assembly and disassembly efficiency. This modular design enables the frame to extend and retract flexibly, quickly adapting to the spatial requirements of different work surfaces while ensuring structural stability in high-altitude working environments.

[0062] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 7As shown, to address the problems of poor adaptability of platform steps, low assembly efficiency, and material waste caused by variations in tower diameter in traditional tower maintenance platforms, the platform step 400 is assembled sequentially from several step blocks 410 of different specifications, with adjacent sets of step blocks 410 of the same specification connected by interlocking mechanisms. By employing a combination design of step blocks 410 with differentiated specifications, the flexible adaptability of the platform step 100 is achieved.

[0063] Specifically, several tread blocks 410 of different specifications are prefabricated into standardized modules of varying sizes to match the gradually changing diameter of the tower's conical section. They are assembled sequentially using a progressive combination method to form a continuous working surface that conforms to the tower's contour. Adjacent tread blocks 410 of the same specification are connected using a snap-fit ​​connection method, utilizing a complementary connection structure to achieve rapid positioning and locking. This ensures the mechanical interlocking strength of adjacent modules while simplifying assembly procedures during high-altitude operations. In particular, the snap-fit ​​connection method eliminates the need for traditional bolt fastening, significantly improving assembly efficiency while ensuring structural stability.

[0064] As one of the preferred embodiments, such as Figure 7 , Figure 8 , Figure 11 and Figure 12 As shown, in order to solve the problem of rapid assembly and stable connection between the pedal blocks 410, the pedal block 410 is designed as an isosceles trapezoidal structure. One side end is provided with a first L-shaped side connecting plate 411 facing upward, and the other side end is provided with a second L-shaped side connecting plate 412 facing downward. The second L-shaped side connecting plate 412 can be designed as two that are arranged at a flexible interval. The asymmetrical first L-shaped side connecting plate 411 and second L-shaped side connecting plate 412 on both sides are used to realize the snap-on connection of adjacent pedal blocks.

[0065] Specifically, the first L-shaped side connecting plate 411 is arranged upwards to form a receiving groove, and the second L-shaped side connecting plate 412 is arranged downwards to form an insertion part. When two adjacent pedal blocks 410 are spliced, the second L-shaped side connecting plate 412 can be embedded into the groove of the first L-shaped side connecting plate 411 on the other pedal block 410, forming a vertical limit and a horizontal constraint. This structural design not only ensures the positioning accuracy during assembly, but also improves the shear resistance of the connection part through interlocking.

[0066] Furthermore, to address the issues of unstable connection between the treadle block 410 and the telescopic frame 300, insufficient platform structural strength, and easy displacement of the treadle block 410 during high-altitude operations when traditional scaffolding is erected on tapered sections, two spaced baffles 414 are installed at the bottom of the folded edges 413 at both the inner and outer ends of the treadle block 410. These baffles 414 are connected to the outer telescopic frame 300 for limiting their position. The spaced baffles 414 form a lateral constraint, which, in conjunction with the physical limiting of the telescopic frame 300, prevents the treadle block 410 from slipping on the inclined surface of the tapered section.

[0067] A through hole 415 for mounting a support lug 600 is provided on the left and right sides of the top of the pedal block 410. The symmetrical arrangement of the through holes 415 allows the support lug 600 to bear the tension of the sling evenly, avoiding stress concentration at a single point. At the same time, parallel reinforcing support plates 416 are provided between the folded edges 413 at the inner and outer ends of the bottom of the pedal block 410. The reinforcing support plates 416 form a truss-like support structure at the bottom of the pedal block 410. By arranging them in parallel, they simultaneously resist vertical loads and lateral torques, improving the platform's resistance to deformation.

[0068] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 13 As shown, in order to further improve the safety of the maintenance platform and avoid the risk of maintenance personnel falling off the platform during maintenance operations, side support columns 500 are set around the four sides of the maintenance platform. The side support columns 500 can be connected by ropes to form a guardrail structure.

[0069] Specifically, an upright plate 501 is provided on the inner side wall of the lower end of the side support column 500. Three second side shafts 502 arranged in an inverted triangle are provided on the upright plate 501. Each second side shaft 502 has a third pin 503 embedded at its outer end, which is inserted into the corresponding telescopic frame 300. The three inverted triangle second side shafts 502 form a three-point stable support surface. With the rigid connection of the third pins 503, the radial stress generated at different heights of the conical section can be effectively distributed when the umbrella-shaped structure is unfolded, ensuring a reliable connection between the end of the frame and the side support column 500.

[0070] In some of these embodiments, such as Figure 1 , Figure 3 , Figure 4 , Figure 14 and Figure 15 As shown, in order to solve the problems of traditional maintenance platform lifting lug structure being non-removable, having poor installation stability, and being unable to meet the needs of modular rapid assembly, the support lifting lug 600 adopts a split design of triangular connector 610 and lifting lug body 620, so as to realize the rapid disassembly and reuse of the lifting lug structure.

[0071] Specifically, the supporting lug 600 includes a triangular connector 610 and a lug body 620 detachably mounted on top of the triangular connector 610. The triangular connector 610 is V-shaped and fitted onto the bottom of the telescopic frame 300, utilizing the adaptability of its geometric shape to enhance the clamping effect on the telescopic frame 300. Furthermore, the left and right ends of the triangular connector 610 are respectively connected to the two ends of the lug body 620 through the through holes 415 on the platform pedal 400 via locking bolts 630, forming a mechanical locking structure. This ensures a rigid connection between the lug body 620 and the telescopic frame 300, while also preventing the locking bolts 630 from loosening due to the limiting effect of the through holes 415 on the platform pedal 400.

[0072] In addition, such as Figure 14 and Figure 15 As shown, a T-shaped upright plate 621 is vertically mounted on the top of the lifting lug body 620, and the inner end of the T-shaped upright plate 621 is set as a lifting lug plate 622. The T-shaped cross-section design of the T-shaped upright plate 621 at the top of the lifting lug body 620 enhances the bending strength of the upright plate, while the lifting lug plate 622 is set on the inner end of the T-shaped upright plate 621 to avoid interference between the lifting cable and the tower structure.

[0073] The modular, new-type umbrella-shaped tower maintenance platform, including its supporting central wheel 100, central tie column 200, several sets of telescopic frames 300, platform treads 400, side tie columns 500, and support lugs 600, is made of high-performance aluminum alloy. Aluminum alloy is resistant to rust and damage, significantly extending the platform's lifespan while greatly reducing its weight. This effectively solves the problem of existing scaffolding requiring brand-new materials and rejecting older ones, while also reducing material waste and achieving excellent cost-saving and weight-reduction effects.

[0074] In terms of safety, the modules of this modular new umbrella-shaped tower maintenance platform are connected and secured in a detachable manner, making installation and disassembly very convenient. Furthermore, the use of slings to tighten the retractable frame 300 and safety ropes for personnel significantly reduces the probability of accidents, ensuring safe and reliable operation.

[0075] Combination Figures 1 to 15As shown, the assembly method of this modular new umbrella-shaped tower maintenance platform is as follows: First, the central support column 200 and the supporting wheel 100 are connected by bolt assemblies, and the supporting wheel 100 is interlocked with each telescopic frame 300 by the first pin 113. The junctions of each triangular support 310 are interlocked by the second pin 311 and secured with R-clips to ensure a tight connection. Second, on the triangular support 310 at the outer end of the telescopic frame 300, the side support columns 500 are connected by the third pin 503. Then, the different sized platform blocks 410 on the platform platform 400 are assembled layer by layer from the inside out. Finally, each support lifting lug 600 is installed at the corresponding position on the platform platform 400. In use, external slings are used to connect the support lifting lug 600 to the central support lifting lug 202 at the top of the central support column 200.

[0076] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
