Description

Technical Field

[0001] This utility model relates to the field of layered adjustable support technology, and in particular to a layered adjustable support frame for boiler water-cooled wall tube assembly maintenance. Background Technology

[0002] Boiler water-cooled wall tube assemblies are important heat-receiving surface components of boilers. They are arranged around the inner wall of the boiler furnace and consist of multiple seamless steel tubes connected to each other via headers. During boiler operation, treated water or a steam-water mixture flows inside the tubes. The high-temperature flames and flue gas generated by fuel combustion in the furnace transfer heat to the tube walls through radiation heat exchange, causing the medium inside the tubes to heat up and vaporize, thereby absorbing a large amount of heat, reducing the furnace temperature, protecting the furnace walls, and effectively cooling the high-temperature flue gas. This improves the boiler's thermal efficiency and ensures the safe and stable operation of the boiler, playing a crucial role in the entire thermal cycle system.

[0003] Traditional maintenance often relies on scaffolding and simple supports, which suffer from time-consuming setup, poor support stability, and inconvenient adjustment, resulting in low maintenance efficiency and high safety risks. Layered adjustable support frames offer significant improvements. They can be adjusted according to maintenance needs, saving installation time. The layered structure provides stable support, distributes the weight of pipe assemblies, and reduces the risk of single-point stress. The modular design facilitates disassembly and transportation, reducing manpower input. Adjustable components enable precise adjustment, ensuring the accuracy of maintenance operations. This effectively compensates for the shortcomings of traditional methods, provides reliable support for maintenance work, and improves maintenance quality and safety.

[0004] Traditional support structures lack precise positioning and fixing devices, making it difficult to place and arrange pipes stably and neatly during maintenance. This can lead to pipe shifting and tipping, affecting maintenance efficiency and quality. When not in use, the lack of reliable fixing measures can cause pipes to slip, posing a safety hazard. After maintenance, due to the unreasonable design of the support structure, removing the pipes requires a lot of manpower and time, is cumbersome, and causes scratches and collision damage to the pipe surface. In addition, the existing support structures have limited functionality and cannot meet the requirements of efficient, safe, and convenient modern maintenance. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a layered adjustable support frame for boiler water-cooled wall tube assembly maintenance. It aims to improve the existing technology, which lacks precise positioning and fixing devices, making it difficult to place the tubes stably during maintenance, affecting maintenance efficiency and quality. When idle, the lack of reliable fixing measures poses a safety hazard. Furthermore, after maintenance, pulling out the tubes requires a lot of manpower and time, which cannot meet the requirements of efficient, safe and convenient modern maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a layered adjustable support frame for boiler water-cooled wall tube assembly maintenance, comprising two bearing plates, multiple connecting rods fixedly connected between the two bearing plates, a common mounting block fixedly connected to the top of each of the multiple connecting rods, two telescopic rods fixedly connected to the rear inner side of each of the two bearing plates, a common stop block fixedly connected to the output end of each of the two telescopic rods, slide rail 1 provided at the upper left and right ends of the inner side of each of the two bearing plates, the bottom of each of the two stop blocks sliding within the multiple slide rail 1, a placement box slidably connected to the middle inner side of each of the bearing plates, sliders fixedly connected to the left and right sides of the bottom of each of the two placement boxes, a pressure sensor fixedly connected to the bottom inner side of each of the two bearing plates, slide rail 2 provided at the middle left and right ends of the inner side of each of the two bearing plates, and multiple buffer mechanisms provided at the top of each of the two placement boxes.

[0007] As a further description of the above technical solution:

[0008] The plurality of buffer mechanisms include a plurality of grooves, which are respectively formed on the top of the two placement boxes. A spring is fixedly connected inside the plurality of grooves. A rubber locking block is fixedly connected to the top of the plurality of springs. A plurality of sponge pads are fixedly connected to the top of the plurality of rubber locking blocks. A fan is fixedly connected inside the mounting block.

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

[0010] The top left and right sides of the mounting block are threaded with buckles, and the front and rear sides of the two buckles are threaded with two threaded pins.

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

[0012] Two power blocks are fixedly connected to the top left side of the top support plate, and power indicator lights are fixedly connected to the outside of each of the two power blocks.

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

[0014] The bottom support plate is fixedly connected to the top left and right sides with concave bases, and a storage box is fixedly connected between the two adjacent concave bases.

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

[0016] Mounting plates are fixedly connected to the rear outer sides of both bearing plates, and multiple heat dissipation fins are fixedly connected to the exterior of both mounting plates.

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

[0018] Power strips are fixedly connected to the front and rear sides of the bottom of the mounting block, and light strips are fixedly connected to the bottom of the two power strips.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the placement box can slide by the cooperation of the slide rail and the slider, which makes it easy to adjust the spacing and achieve neat arrangement of the pipe group. The placement box provides a stable support surface. When not under maintenance, the telescopic rod pushes the stop block to slide to the appropriate position to prevent the pipe from shifting and effectively prevent it from slipping. After maintenance, the slide rail provides a guide for the placement box to be pulled out along with the pipe. The operation is convenient and efficient, ensuring that the structure can be effectively and accurately positioned and fixed, meeting the requirements of efficient, safe and convenient modern maintenance.

[0023] 2. In this utility model, when the tube assembly is placed on the placement box, the spring in the groove is compressed and contracts, absorbing the impact force of the tube assembly falling through elastic deformation, thus avoiding damage to the tube assembly from rigid collision. The rubber locking block is soft and has a rough surface, which increases the frictional resistance when in contact with the tube assembly, preventing the tube assembly from sliding. The sponge pad further adheres to the surface of the tube assembly, increasing the contact area while providing buffer protection, further enhancing the friction force, ensuring the tube assembly is placed stably, and comprehensively protecting the safety and stability of the tube assembly placement.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides a layered adjustable support frame for boiler water-cooled wall tube assembly maintenance, comprising two bearing plates 1, multiple connecting rods 3 fixedly connected between the two bearing plates 1, the top of the multiple connecting rods 3 being fixedly connected to the same mounting block 4, two telescopic rods 5 being fixedly connected to the inner rear side of the two bearing plates 1, the output end of the two telescopic rods 5 being fixedly connected to the same stop block 7, slide rails 6 being provided at the upper left and right ends of the inner side of the two bearing plates 1, the bottom of the two stop blocks 7 sliding inside the multiple slide rails 6, a placement box 8 being slidably connected to the middle of the inner side of the bearing plates 1, sliders 9 being fixedly connected to the bottom left and right sides of the two placement boxes 8, the placement boxes 8 being slidable by the cooperation of the slide rails 6 and the sliders 9, facilitating the adjustment of the spacing, pressure sensors 10 being fixedly connected to the bottom of the inner side of the two bearing plates 1, slide rails 11 being provided at the middle left and right ends of the inner side of the two bearing plates 1, and multiple buffer mechanisms 2 being provided at the top of the two placement boxes 8;

[0034] Specifically, the two support plates 1 provide a stable base for the entire support frame. The connecting rod 3 at the top is connected to the mounting block 4, enhancing the overall strength of the support frame. The telescopic rod 5 and the stop block 7 ensure the stable placement of the tube assembly. After the water-cooled wall tube assembly is placed on the placement box 8, the telescopic rod 5 can push the stop block 7 to slide along the slide rail 6 until the tube assembly is firmly fixed, preventing the tube assembly from slipping when not being repaired and ensuring safe storage. The placement box 8 and the support plate 1 cooperate through the slide rail 6 and the slider 9. Maintenance personnel can adjust the spacing between the placement boxes 8 according to the size of the tube assembly, so that the tube assembly can be placed in an orderly manner. The tubes are neatly arranged and securely placed, facilitating subsequent inspection and maintenance. The pressure sensor 10, installed on the bottom inner side of the support plate 1, can monitor the weight of the tube assembly on the placement box 8 in real time. Once the preset safety value is exceeded, an alarm will be issued to prevent the support frame from causing safety hazards due to overload. The slide rail 2 11 provides a longitudinal sliding track for the placement box 8. After maintenance is completed, maintenance personnel can easily pull out the placement box 8 along the slide rail 2 11 to quickly remove the tube assembly, greatly improving work efficiency. The top of both placement boxes 8 is equipped with multiple buffer mechanisms 2 to buffer the tube assembly.

[0035] Reference Figure 4 , Figure 5 and Figure 6 The multiple buffer mechanisms 2 include multiple grooves 201, which are respectively opened on the top of the two placement boxes 8. Springs 202 are fixedly connected inside the multiple grooves 201 for buffering the tube assembly. Rubber locking blocks 203 are fixedly connected to the top of the multiple springs 202. Multiple sponge pads 204 are fixedly connected to the top of the multiple rubber locking blocks 203. A fan 205 is fixedly connected inside the mounting block 4.

[0036] Specifically, the spring 202 inside the groove 201 absorbs the impact force with its elastic deformation at the moment the tube assembly is placed, slowing down the falling speed of the tube assembly and avoiding rigid collisions. The rubber locking block 203 is flexible and has a rough surface, which increases the friction when in contact with the tube assembly to prevent slippage. The sponge pad 204 further fits the surface of the tube assembly, which can not only buffer minor vibrations, but also increase the contact area and enhance the friction, ensuring that the tube assembly is placed stably. Meanwhile, the fan 205 inside the mounting block 4 runs continuously to accelerate air circulation and dissipate the heat generated by the placement and movement of the tube assembly in a timely manner, preventing local overheating from damaging the tube assembly and support frame components, thus ensuring the safety and stability of the tube assembly in all aspects of maintenance.

[0037] Reference Figure 1 , Figure 2 and Figure 3The top left and right sides of the mounting block 4 are threaded with buckles 12 for easy installation and disassembly. The front and rear sides of the two buckles 12 are threaded with two threaded nails 13. The top left side of the top support plate 1 is fixedly connected with two power blocks 14. The exterior of the two power blocks 14 is fixedly connected with power indicator lights 15. The top left and right sides of the bottom support plate 1 are fixedly connected with concave bases 16. The adjacent concave bases 16 are fixedly connected with storage boxes 17.

[0038] Specifically, the buckle 12 on the top of the mounting block 4 is easily installed and removed via a threaded connection, and further reinforced with threaded nails 13, which can quickly fix various auxiliary equipment or protective devices, improving the functional expandability and flexibility of the support frame. The power block 14 is installed on the outside of the top support plate 1 to provide power to the power indicator light 15, which can intuitively display the power supply status, making it easy for maintenance personnel to keep track of the equipment's power consumption. The bottom support plate 1 has a concave base 16 and a storage box 17 at the bottom. The concave base 16 enhances the contact stability between the support frame and the ground, and the storage box 17 can be used to store maintenance tools and parts, making it more convenient to access tools on site, optimizing the maintenance operation process, and improving overall work efficiency.

[0039] Reference Figure 1 , Figure 2 and Figure 3 Mounting plates 18 are fixedly connected to the rear sides of the two bearing plates 1. Multiple heat dissipation fins 19 are fixedly connected to the exterior of the two mounting plates 18 for heat dissipation. Power strips 20 are fixedly connected to the front and rear sides of the bottom of the mounting block 4. Light strips 21 are fixedly connected to the bottom of the two power strips 20. Mounting boxes 22 are fixedly connected to the left and right ends of the bottom of the mounting block 4. Multiple desiccants 23 are fixedly connected inside the two mounting boxes 22.

[0040] Specifically, the heat dissipation fins 19 on the mounting plate 18 can effectively increase the heat dissipation area, dissipate the heat generated by the electric components during the operation of the support frame in a timely manner, ensure stable operation of the equipment, and extend its service life. The power strip 20 and the light strip 21 provide sufficient lighting for maintenance work, making it convenient for maintenance personnel to clearly see the details of the water-cooled wall tube assembly, improving the accuracy and efficiency of maintenance. The desiccant 23 in the mounting box 22 can absorb moisture from the surrounding environment, prevent humid air from corroding the tube assembly and the metal parts of the support frame, ensure that the tube assembly is stored and maintained in a dry environment, reduce the risk of rust caused by moisture, comprehensively protect the performance and safety of the equipment, and optimize the maintenance working environment.

[0041] Working principle: The top connecting rod 3 of the bearing plate 1 and the mounting block 4 ensure that the support frame has sufficient strength to bear the weight of the pipe assembly. During the placement and fixing of the pipe assembly, the placement box 8 and the bearing plate 1 are neatly arranged through the sliding cooperation of the slide rail 1 6 and the slider 9. After the pipe assembly is placed in place, the telescopic rod 5 pushes the stop block 7 to slide along the slide rail 1 6 to form a tight fixation on the pipe assembly, preventing it from slipping when idle and ensuring safe storage. In terms of operation monitoring, the pressure sensor 10 at the bottom of the inner side of the bearing plate 1 continuously monitors the weight of the pipe assembly on the placement box 8. Once the weight exceeds the preset safety threshold, an alarm mechanism is triggered to remind the staff to deal with it in time, effectively avoiding safety hazards caused by overload. After maintenance, the slide rail 2 11 provides a longitudinal sliding track for the placement box 8. Maintenance personnel can easily pull out the placement box 8 along this track to quickly remove the pipe assembly, simplifying the disassembly process and significantly improving the efficiency of maintenance work. All components work together to form a complete and efficient work loop from pipe assembly placement and operation monitoring to final disassembly.

[0042] Furthermore, when the tube assembly is placed on the placement box 8, the spring 202 in the groove 201 absorbs the impact force generated by the falling tube assembly through elastic deformation, converting kinetic energy into elastic potential energy of the spring 202, slowing down the falling speed of the tube assembly, avoiding rigid collision between the tube assembly and the placement box 8, and protecting the surface of the tube assembly from damage. The rubber locking block 203, with its flexible texture and rough surface, makes close contact with the tube assembly, significantly increasing the friction between the two and preventing the tube assembly from sliding on the placement box 8. The sponge pad 204 further adheres to the surface of the tube assembly, buffering minor vibrations while further strengthening the friction by increasing the contact area, providing double protection for the stable placement of the tube assembly. Meanwhile, the fan 205 in the mounting block 4 runs continuously, forcing airflow and accelerating the dissipation of heat generated by the friction of the tube assembly placement and movement, avoiding heat accumulation that could lead to local overheating, and preventing high temperatures from damaging the material properties of the tube assembly and the support frame components. From buffering and fixing to heat dissipation, the safety and stability of the tube assembly are fully guaranteed during the maintenance process.

[0043] 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.
