[0001] This utility model relates to the field of boiler support structure technology, specifically to a support structure and a biomass boiler system. Background Technology

[0002] The existing biomass direct-fired boiler's central platform is a two-span, multi-story steel frame structure with a total height of over twenty meters. The main components of the steel frame include hot-rolled H-beam columns, hot-rolled H-beam beams, and diagonal bracing using channel steel sections. The central platform primarily facilitates workers' observation of equipment such as the flue gas cooler and economizer, allowing them to confirm whether the temperature is within a safe range. It is also used for the maintenance and adjustment of these devices.

[0003] Publication number CN203364119U discloses a novel biomass incineration boiler. The incineration boiler includes a boiler body, a settling chamber, a reciprocating grate, a steel frame, and a secondary air system. The boiler body includes a furnace water-cooled wall and a convective heating surface. The boiler body and the secondary air system are both supported on the steel frame. The tail heating surface includes an economizer and an air preheater. Both the economizer and the air preheater are installed on the steel frame.

[0004] Currently, when assembling steel frames, the general installation method is to hoist the components and weld them on site. However, the welding position of the maintenance platform usually needs to be flexibly adjusted according to the actual situation. But the lack of auxiliary positioning devices for the maintenance platform during welding reduces welding efficiency. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a support structure and biomass boiler system. This solves the technical problem that the existing technology generally adopts the installation scheme of hoisting loose parts and welding on site. However, the welding position of the maintenance platform usually needs to be flexibly adjusted according to the actual situation, but the lack of auxiliary positioning device for the maintenance platform during welding reduces the welding efficiency.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: In a first aspect, this utility model provides a support structure, comprising: A support assembly includes a support frame and a mounting part. The support frame has a maintenance position and a boiler position arranged sequentially along a horizontal direction. The mounting part is installed on the support frame and located at the maintenance position. The platform component includes a maintenance platform and an adjustment unit. The adjustment unit is installed on the maintenance platform and has an adjustment end extending out of the maintenance platform. The adjustment end allows the maintenance platform to be raised or lowered and can be maintained in the adjusted position, and is connected to the mounting unit.

[0007] In some embodiments, the maintenance platform is located above the mounting section and has an adjustment channel along the direction close to the mounting section; The adjustment part includes an adjustment arm and a locking member. The adjustment arm passes through the adjustment channel and can move relative to the maintenance platform in a direction close to and away from the mounting part. The end of the adjustment arm close to the mounting part can press against the mounting part and form the adjustment end. The locking member connects the adjustment arm and the maintenance platform and can lock the adjustment arm to the maintenance platform and unlock the adjustment arm.

[0008] In some embodiments, a plurality of mounting parts are provided, and the plurality of mounting parts are arranged at intervals along the periphery of the maintenance platform; a plurality of adjustment channels are provided, and the plurality of adjustment channels correspond one-to-one with the plurality of mounting parts. Multiple adjusting arms and multiple locking components are provided. The multiple adjusting arms are movably inserted into the multiple adjusting channels. The multiple locking components are connected to the multiple adjusting arms and connected to the maintenance platform.

[0009] In some embodiments, the mounting portion is provided with a limiting channel in a direction away from the maintenance platform, the limiting channel opening on the side near the maintenance platform for the insertion of the adjusting arm.

[0010] In some embodiments, the adjusting arm is provided with external threads, and the locking member includes a locking nut, which is threadedly connected to the adjusting arm and located on the side of the adjusting channel near the mounting portion.

[0011] In some embodiments, a plurality of locking nuts are provided, and each plurality of locking nuts is threadedly connected to the adjusting arm; and / or, The internal thread of the locking nut and the external thread of the adjusting arm are self-locking threads.

[0012] In some embodiments, a plurality of mounting portions are provided, and the plurality of mounting portions are spaced apart from the support frame in a vertical direction; The adjustment unit can be selectively connected to any of the mounting units.

[0013] In some embodiments, the support structure further includes a reinforcing connecting plate, which is used to weld to the maintenance platform and the support frame when the adjustment end is held in the activated position.

[0014] In some embodiments, the support frame includes multiple steel frames arranged sequentially in a horizontal direction, and a connecting beam connects two adjacent steel frames. The maintenance position and the boiler position are formed between the multiple steel frames, and their arrangement directions intersect with the arrangement direction of the multiple steel frames.

[0015] Secondly, this solution also provides a biomass boiler system, which includes the support structure described in any of the above.

[0016] Compared with existing technologies, the support structure provided by this utility model allows for the adjustment of the movable end according to actual needs, thereby adjusting the distance between the adjustment end and the maintenance platform. Since the maintenance platform is connected to the support frame sequentially via the adjustment part and the mounting part, the relative position between the maintenance platform and the support frame is adjusted synchronously when the distance between the adjustment end and the maintenance platform changes, thus meeting actual needs. Furthermore, once the distance between the adjustment end and the maintenance platform is adjusted to a preset value, it can maintain the adjusted position, ensuring that the positions of the maintenance platform and the support frame are relatively fixed, achieving positioning of the maintenance platform. At this point, workers can weld the maintenance platform to the support frame. In this way, the relative position of the maintenance platform can be flexibly adjusted according to actual needs, and it also plays a role in assisting in positioning the maintenance platform, improving welding efficiency.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem that the installation scheme typically involves hoisting individual components and welding on-site, but the welding position of the maintenance platform often needs to be flexibly adjusted according to the actual situation, and the lack of an auxiliary positioning device for the maintenance platform during welding reduces welding efficiency, this utility model provides a support structure that can flexibly adjust the relative position of the maintenance platform according to actual needs, and also play an auxiliary positioning role for the maintenance platform, thereby improving welding efficiency.

[0021] It should be noted that the support structure described in this utility model is used in, but not limited to, biomass boiler systems. For ease of explanation, this utility model only uses the application of the support structure in a biomass boiler system as an example. The principle of the support structure applied to other types of equipment is essentially the same as that applied to a biomass boiler system, and will not be described in detail here.

[0022] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the support structure in one embodiment of the present invention. The support structure includes a support component 1 and a platform component 2. The support component 1 includes a support frame 11 and a mounting part 12. The support frame 11 is provided with a maintenance position 13 and a boiler position 14 in sequence along the horizontal direction. The mounting part 12 is installed on the support frame 11 and located at the maintenance position 13. The platform component 2 includes a maintenance platform 21 and an adjustment part 22. The adjustment part 22 is installed on the maintenance platform 21 and has an adjustment end 221 extending out of the maintenance platform 21. The adjustment end 221 allows the maintenance platform 21 to be raised or lowered and can be maintained in the adjusted position, and is connected to the mounting part 12. Specifically, the adjustment end 221 can move closer to and further away from the maintenance platform 21 and can be maintained in the adjusted position.

[0023] In the support structure provided by this utility model, the adjustable end 221 can be moved according to actual needs, thereby adjusting the distance between the adjustable end 221 and the maintenance platform 21. Since the maintenance platform 21 is connected to the support frame 11 via the adjusting part 22 and the mounting part 12, when the distance between the adjusting end 221 and the maintenance platform 21 changes, the relative position between the maintenance platform 21 and the support frame 11 is adjusted synchronously to meet actual needs. Furthermore, once the distance between the adjusting end 221 and the maintenance platform 21 is adjusted to a preset value, it can be maintained in the adjusted position, thereby ensuring that the positions of the maintenance platform 21 and the support frame 11 are relatively fixed, achieving positioning of the maintenance platform 21. At this point, workers can weld the maintenance platform 21 onto the support frame 11. Thus, the relative position of the maintenance platform 21 can be flexibly adjusted according to actual needs, and it also plays a role in assisting in positioning the maintenance platform 21, improving welding efficiency.

[0024] It should be noted that the adjustment unit 22 can be configured as multiple hydraulic cylinders, air cylinders or other forms that are detachably mounted on the maintenance platform 21.

[0025] In another embodiment, the maintenance platform 21 is located above the mounting portion 12 and has an adjustment channel 21a along the direction close to the mounting portion 12; the adjustment portion 22 includes an adjustment arm 222 and a locking member 223. The adjustment arm 222 passes through the adjustment channel 21a and can move relative to the maintenance platform 21 in the direction close to and away from the mounting portion 12. The end of the adjustment arm 222 close to the mounting portion 12 can press against the mounting portion 12 and form an adjustment end 221. The locking member 223 connects the adjustment arm 222 and the maintenance platform 21 and can lock the adjustment arm 222 to the maintenance platform 21 and can unlock the adjustment arm 222.

[0026] In this embodiment, the relative position of the maintenance platform 21 and the support frame 11 is adjusted by moving the adjusting arm 222 up and down. After the position is adjusted, the adjusting arm 222 is locked to the support frame 11 by the locking member 223, thereby achieving the positioning of the maintenance platform 21.

[0027] In one embodiment, multiple mounting parts 12 are provided, and the multiple mounting parts 12 are arranged at intervals along the periphery of the maintenance platform 21. Multiple adjustment channels 21a are provided, and the multiple adjustment channels 21a correspond one-to-one with the multiple mounting parts 12. Multiple adjustment arms 222 and locking members 223 are provided respectively. The multiple adjustment arms 222 are movably inserted into the multiple adjustment channels 21a, and the multiple locking members 223 are respectively connected to the multiple adjustment arms 222 and connected to the maintenance platform 21.

[0028] In this embodiment, multiple sets of mounting parts 12, adjustment channels 21a and adjustment parts 22 are arranged at intervals along the periphery of the maintenance position 13, so as to improve the support stability of the maintenance platform 21 through the multiple sets of mounting parts 12 and adjustment parts 22, thereby improving safety.

[0029] It should be noted that the mounting part 12 can be configured as a mounting base or a mounting plate to stably support the adjusting arm 222, or the mounting part 12 can be configured in other forms.

[0030] In another embodiment, please refer to Figures 3 to 5 The installation part 12 is provided with a limiting channel 12a in the direction away from the maintenance platform 21. The limiting channel 12a has an opening on the side close to the maintenance platform 21 and is used for the insertion of the adjusting arm 222.

[0031] In this embodiment, the adjusting arm 222 is inserted into the limiting channel 12a of the mounting part 12 to prevent the adjusting arm 222 from accidentally shifting relative to the mounting part 12, thereby ensuring stable support between the maintenance platform 21 and the support frame 11 and further improving safety performance. Specifically, in this solution, the mounting part 12 is a mounting base with a limiting channel 12a, which is welded to the bracket. Furthermore, it should be understood that the lower end of the limiting channel 12a is blocked.

[0032] It should be noted that, in one embodiment, the locking member 223 is configured as a threaded structure between the adjusting arm 222 and the inner wall of the adjusting channel 21a. In another embodiment, the adjusting arm 222 is provided with a plurality of pin holes spaced apart in the vertical direction, and the locking member 223 is a locking pin, which can be selectively inserted into any of the pin holes.

[0033] In another embodiment, the adjusting arm 222 is provided with external threads, and the locking member 223 includes a locking nut 224, which is threadedly connected to the adjusting arm 222 and is located on the side of the adjusting channel 21a near the mounting part 12.

[0034] In this embodiment, the adjusting arm 222 is restricted from moving upward relative to the maintenance platform 21 by the locking nut 224, so that the mounting part 12 stably supports the maintenance platform 21 via the adjusting arm 222. The structure is simple and reliable, and the adjusting arm 222 and the locking nut 224 can be reused, saving costs.

[0035] In one embodiment, multiple locking nuts 224 are provided, and each locking nut 224 is threadedly connected to the adjusting arm 222; and / or, the internal thread of the locking nut 224 and the external thread of the adjusting arm 222 are self-locking threads.

[0036] In this embodiment, multiple locking nuts 224 are provided to improve the locking stability of the locking member 223 on the adjusting arm 222. Furthermore, the threads of both are set as self-locking threads to prevent the gravity of the maintenance platform 21 from driving the locking nuts 224 to rotate, thereby improving locking stability. It should be noted that the specific structure and principle of the self-locking thread are existing technology and will not be described in detail here.

[0037] In one embodiment, multiple mounting portions 12 are provided, and the multiple mounting portions 12 are spaced apart in the vertical direction on the support frame 11; the adjustment portion 22 can be selectively connected to any of the mounting portions 12.

[0038] In this embodiment, multiple mounting parts 12 are arranged at intervals along the vertical direction on the support frame 11 so that the adjustment part 22 can be connected to the mounting part 12 at the corresponding position according to actual needs, thereby further improving the flexibility of the position layout of the maintenance platform 21.

[0039] In one embodiment, the support structure further includes a reinforcing connecting plate 3, which is used to weld to the maintenance platform 21 and the support frame 11 when the adjustment end 221 is held in the activated position.

[0040] In this embodiment, after the position of the maintenance platform 21 is adjusted to the preset position, the adjusting arm 222 plays an auxiliary positioning role for the maintenance platform 21. This allows the welding personnel to weld the maintenance platform 21 onto the support frame 11, and further improve the connection strength of the maintenance platform 21 by simultaneously welding the support frame 11 and the maintenance platform 21 through the reinforcing connecting plate 3. It should be noted that in this solution, the maintenance platform 21 is designed as a grating plate.

[0041] In one embodiment, please refer to Figure 6 The support frame 11 includes multiple steel frames 111, which are arranged sequentially in the horizontal direction. A connecting beam 112 connects two adjacent steel frames 111. The maintenance position 13 and the boiler position 14 are formed between the multiple steel frames 111, and their arrangement directions intersect with the arrangement direction of the multiple steel frames 111.

[0042] In this embodiment, multiple steel frames 111 are connected sequentially via connecting beams 112 to improve the support strength of the support frame 11. Simultaneously, multiple diagonal braces 4 are installed at the boiler position 14 to ensure that the support frame 11 can stably and effectively support the boiler. Furthermore, in one embodiment, connecting holes are provided at both the upper and lower ends of the steel frame 111, allowing the steel frames 111 to be stacked as needed to change the height of the support frame 11.

[0043] Furthermore, this utility model also provides a biomass boiler system, which includes the support structure described in any of the above embodiments. It should be noted that the detailed structure of the support structure of the biomass boiler system can be referred to the embodiments of the above support structures, and will not be repeated here. Since the above support structure is used in the biomass boiler system of this utility model, the embodiments of the biomass boiler system of this utility model include all the technical solutions of all the embodiments of the above support structure, and the achieved technical effects are also completely the same, and will not be repeated here.

[0044] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below: In this design, multiple sets of mounting parts 12 and adjusting parts 22 are spaced around the periphery of the maintenance position 13. This allows the length of the adjusting arm 222 below the adjusting channel 21a to be changed by using the locking nut 224 on the movable adjusting arm 222. This also allows for flexible adjustment of the height of the maintenance platform 21. After adjustment to the preset position, the locking nut 224 stops the maintenance platform 21, at which point the adjusting arm 222 is inserted into the limiting channel 12a of the mounting part 12. Thus, the mounting part 12 and adjusting part 22 provide auxiliary positioning for the maintenance platform 21, which is then welded to the support frame 11, improving welding efficiency.

[0045] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
