Description

Technical Field

[0001] The utility model belongs to the technical field of boiler fixing, and in particular relates to a steel structure used for fixing a horizontal boiler in a power station. Background Art

[0002] In power plant operation, the stability and safety of the horizontal boiler are crucial to ensure the continuity and safety of power supply. Although the traditional boiler fixing method mainly relies on static steel structure brackets to provide basic support functions for the boiler, these traditional methods are often inadequate in dealing with dynamic factors such as vibration, impact and temperature changes generated during boiler operation.

[0003] The Chinese utility model patent document with the publication number CN 216244223U records a steel structure for fixing the horizontal boiler of a power station, which improves the traditional fixing method to a certain extent and attempts to control the spacing of the support mechanism through the transmission method of gear toothed belt to adapt to the needs of boilers of different sizes. However, this design still has significant defects and problems.

[0004] First, the gear belt transmission method used makes the structural design not compact enough, which not only increases the complexity of the overall structure and manufacturing cost, but also may lead to reduced transmission effect and accuracy. In power plant operation, the accuracy and stability of the boiler fixing structure are extremely high. Therefore, the shortcomings of this design cannot meet the current demand for precise boiler fixing structure.

[0005] Secondly, the support structure in this design lacks sufficient anti-interference function. In a power plant environment, the boiler may be disturbed by various external factors, such as vibration, impact, etc. If the support structure cannot effectively resist these interferences, it may fall off or fail to accurately build an efficient limit function with the limit block, thus posing a threat to the stability and safety of the boiler.

[0006] Therefore, it is very necessary to invent a steel structure for fixing the horizontal boiler of a power station. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a steel structure for fixing a horizontal boiler in a power station, comprising a boiler fixing base, a mobile platform mechanism, a positioning seat and a side seat, wherein the mobile platform mechanism is installed on the boiler fixing base, and the positioning seat is fixedly installed thereon, the positioning seat is located between the two side seats and the mobile platform mechanism, and the side seat is fixedly installed on the mobile platform mechanism;

[0008] The boiler fixed base comprises a base, a slide rail protrusion, a rack and ratchet teeth. The positioning seat is fixedly mounted on the base. The slide rail protrusions are mirror-imaged on the inner and outer surfaces of the base. The rack is arranged between the inner slide rail protrusions, and the ratchet teeth are arranged between the outer slide rail protrusions. The rack and the ratchet teeth are engaged or meshed with the mobile platform mechanism; the mobile platform mechanism is rollingly connected with the slide rail protrusions.

[0009] The mobile platform mechanism includes a platform seat, a worm, a driving component, a worm wheel, a driving gear, a mounting shaft, a torque spring, a ratchet plate, a twist handle and a roller, and the side seat is fixedly mounted on the platform seat; the worm is rotatably mounted inside the platform seat, and either end of the worm rotates through the platform seat and is fixed to the output end of the driving component fixedly mounted outside it; the worm is meshingly connected with the worm wheel, and the worm wheel and the driving gear are both rotatably mounted in the platform seat through the same rotating shaft; the driving gear is meshingly connected with the rack; the roller is fixedly mounted on the mounting shaft rotatably mounted on the platform seat, and the roller is rollingly assembled on the slide rail protrusion; four of the mounting shafts are elastically connected to the ratchet plate through the torque spring, and the twist handle is fixedly mounted on the ratchet plate, and the ratchet plate is meshingly connected with the ratchet teeth.

[0010] Preferably, the positioning seat and the side seat are provided with arc surfaces that fit with the outer surface of the boiler and are fixedly connected thereto, and elastic shock-absorbing pad structures are provided on the positioning seat and the side seat.

[0011] Preferably, a total of four groups of the slide rail protrusions are arranged on the inner and outer surfaces of the base, a group of the racks are arranged on the inner surface, and a group of the ratchet teeth are arranged on the outer surface, two in a group.

[0012] Preferably, the platform seat is a "T"-shaped structure, and two sets of transmission mechanisms consisting of the worm, driving component, worm wheel and driving gear are installed on the platform seat. The worm wheel and driving gear are located on one side of the worm, and the worm wheel and driving gear are fixedly mounted on the same rotating shaft.

[0013] Preferably, the platform seat is rotatably mounted with four groups of the mounting shafts, two in a group, respectively arranged on the inner side and the outer side of the base, and each of the mounting shafts is fixedly mounted with two of the rollers, which roll together with the protrusions of the slide rails.

[0014] Preferably, the two outer groups of mounting shafts are installed with auxiliary support structures consisting of the torque spring, the ratchet plate and the twist handle, and there are two groups in total, all of which are arranged on the outer side of the platform seat. The ratchet plate is firmly engaged with the ratchet teeth with the help of the elastic force of the torque spring.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In view of the limitation of the traditional technology that relies on gear belt transmission, this utility model cleverly introduces an innovative mobile platform mechanism that combines gear racks with worm gears. This design not only significantly improves the compactness of the structure, but also demonstrates extremely high transmission torque, transmission stability and accuracy with its efficient transmission mechanism. In the context of the increasing requirements for the accuracy of boiler fixed structures, this design can undoubtedly fully meet the actual needs.

[0017] In addition, in order to further optimize the stability of the structure and reduce the interference of external factors, the utility model specially designs the auxiliary support structure on the outside of the boiler fixed base, away from the boiler body. This layout minimizes the impact of dynamic factors such as vibration and impact generated during the operation of the boiler on the auxiliary support structure. At the same time, with the elastic force of the torque spring, the pawl plate and the ratchet teeth can be firmly engaged, together constructing an efficient and stable limit function, ensuring the stability and safety of the boiler during the fixing process.

[0025] As attached Figure 1 To Attachment Figure 3 As shown:

[0026] The utility model provides a steel structure for fixing a horizontal boiler in a power station, comprising a boiler fixing base 1, a mobile platform mechanism 2, a positioning seat 3 and a side seat 4. The mobile platform mechanism 2 is installed on the boiler fixing base 1, and the positioning seat 3 is fixedly installed thereon. The positioning seat 3 is located between the two side seats 4 and the mobile platform mechanism 2, and the side seat 4 is fixedly installed on the mobile platform mechanism 2.

[0027] The boiler fixed base 1 includes a base 11, a slide rail protrusion 12, a rack 13 and ratchet teeth 14. The positioning seat 3 is fixedly installed on the base 11. The slide rail protrusions 12 are mirror-imaged on the inner and outer surfaces of the base 11. The rack 13 is arranged between the inner slide rail protrusions 12, and the ratchet teeth 14 are arranged between the outer slide rail protrusions 12. The rack 13 and the ratchet teeth 14 are both engaged or meshed with the mobile platform mechanism 2; the mobile platform mechanism 2 is rollingly connected with the slide rail protrusions 12. The boiler fixed base 1 provides a basis for the transmission stability and accuracy of the mobile platform mechanism 2.

[0028] The mobile platform mechanism 2 includes a platform seat 21, a worm 22, a driving component 23, a worm wheel 24, a driving gear 25, a mounting shaft 26, a torque spring 27, a ratchet plate 28, a twist handle 29 and a roller 20. The side seat 4 is fixedly mounted on the platform seat 21; the worm 22 is rotatably mounted inside the platform seat 21, and either end of the worm 22 rotates through the platform seat 21 and is fixed to the output end of the driving component 23 fixedly mounted outside the platform seat 21; the worm 22 is meshed and connected with the worm wheel 24, and the worm wheel 24 and the driving gear 25 are both rotatably mounted in the platform seat 21 via the same rotating shaft; the driving gear 25 is meshed and connected with the rack 13; the roller 20 is fixedly mounted on the mounting shaft 26 rotatably mounted on the platform seat 21, and the roller 20 is rollingly assembled on the slide rail protrusion 12; four of the mounting shafts 26 are elastically connected to the pawl plate 28 via the torque spring 27, and the twist handle 29 is fixedly mounted on the pawl plate 28, and the pawl plate 28 is meshed and connected with the ratchet teeth 14. The mobile platform mechanism 2 not only significantly improves the compactness of the structure, but also exhibits extremely high transmission torque, transmission stability and accuracy by virtue of the efficient transmission mechanism. Embodiment 1:

[0029] Specifically, the positioning seat 3 and the side seat 4 are provided with arc surfaces that fit with the outer surface of the boiler and are fixedly connected thereto, and both the positioning seat 3 and the side seat 4 are provided with elastic shock-absorbing pad structures.

[0030] Specifically, the inner and outer surfaces of the base 11 are provided with four sets of slide rail protrusions 12, which not only provide a smooth sliding track for the mobile platform mechanism 2, but also enhance the structural strength of the base 11. In particular, a set of racks 13 are provided on the inner surface of the base 11, and a set of ratchet teeth 14 are provided on the outer surface, two in each set, which are respectively used to engage or mesh with the transmission components of the mobile platform mechanism 2. The inner rack 13 is designed to cooperate with the driving gear 25 on the mobile platform mechanism 2, and the moving distance of the platform is accurately controlled by the rotation of the gear, so as to achieve accurate positioning of the boiler. This design ensures the accuracy and reliability of positioning, so that the boiler can be firmly fixed on the base 11. The outer ratchet teeth 14 cooperate with the ratchet plate 28 on the mobile platform mechanism, and the ratchet plate 28 tightly engages with the ratchet teeth 14 with the elastic force of the torque spring 27, forming a locking mechanism. This design allows the platform to be securely locked after being moved to the designated position, preventing displacement caused by external factors such as vibration or impact, and further enhancing the stability of the boiler fixation.

[0031] Specifically, the platform seat 21 is a "T"-shaped structure, and two sets of transmission mechanisms consisting of a worm 22, a driving component 23, a worm wheel 24 and a driving gear 25 are installed on the platform seat 21. The design of this transmission mechanism makes full use of the transmission characteristics between the worm 22 and the worm wheel 24, that is, the worm 22 can drive the worm wheel 24 to rotate, and the worm wheel 24 drives the driving gear 25 to move. It is worth mentioning that the worm wheel 24 and the driving gear 25 are fixedly mounted on the same rotating shaft, which ensures the synchronous movement between the two, thereby improving the transmission accuracy and efficiency. In addition, the worm wheel 24 and the driving gear 25 are located on one side of the worm 22. This layout makes the entire transmission mechanism more compact, reduces the occupied space, and is also convenient for installation and maintenance.

[0032] Specifically, four groups of mounting shafts 26 are rotatably mounted on the platform seat 21. These mounting shafts 26 are arranged in groups of two, and are carefully arranged on the inner and outer sides of the base 11, respectively, to ensure the stable support and smooth movement of the platform seat 21 on the base 11. Two rollers 20 are fixedly mounted on each mounting shaft 26, and these rollers 20 are tightly matched with the slide rail protrusions 12 on the base 11 to form rolling contact. This design enables the platform seat 21 to slide easily on the base 11, and can maintain a stable running track and smooth sliding experience whether it is fine-tuning or large-scale movement. Through the cooperation of four groups of mounting shafts 26 and rollers 20, the platform seat 21 can achieve precise and reliable position adjustment on the base 11, ensuring that the boiler can be accurately fixed in the desired position. At the same time, this design also enhances the durability and maintainability of the structure, making the entire boiler fixing system more stable and reliable.

[0033] Specifically, an auxiliary support structure consisting of a torque spring 27, a ratchet plate 28 and a twist handle 29 is specially installed on the two groups of mounting shafts 26 on the outer side of the platform seat 21. Two groups of this structure are arranged, respectively located on the outer side of the platform seat 21, to ensure that stable support is provided at multiple positions. The ratchet plate 28 can be firmly engaged with the ratchet teeth 14 on the outer surface of the base 11 through the elastic force of the torque spring 27. This design not only enhances the connection stability between the platform seat 21 and the base 11, but also effectively prevents displacement caused by external factors such as vibration or impact. The setting of the twist handle 29 allows the operator to easily control the engagement and separation of the ratchet plate 28 and the ratchet teeth 14. When the position of the platform seat 21 needs to be adjusted, the operator can separate the ratchet plate 28 from the ratchet teeth 14 by twisting the handle 29, so that the platform seat 21 can slide smoothly. When the platform seat 21 is moved to the desired position, the operator again engages the pawl plate 28 with the ratchet teeth 14 by twisting the handle 29, thereby locking the position of the platform seat 21 to ensure that it is stable and motionless. Embodiment 2:

[0034] First, when the boiler needs to be fixed on the base 11, the operator places the mobile platform mechanism 2 on the base 11, ensuring that the roller 20 is in close contact with the slide rail protrusion 12 to form a stable rolling support. At this time, the arc surface on the positioning seat 3 and the side seat 4 fits with the outer surface of the boiler, and the elastic shock-absorbing pad structure provides buffering and stabilization.

[0035] Then, the operator starts the driving component 23, which transmits power to the worm 22, and the worm 22 starts to rotate. Since the worm 22 is meshed with the worm wheel 24, the worm wheel 24 starts to rotate under the drive of the worm 22. Since the worm wheel 24 and the driving gear 25 are installed on the same rotating shaft, the driving gear 25 also rotates synchronously.

[0036] Next, the driving gear 25 meshes with the rack 13 inside the base 11, and through the cooperation of the gear and the rack, the platform seat 21 is driven to move along the direction of the slide rail protrusion 12 on the base 11. At this time, the roller 20 rolls on the slide rail protrusion 12, reducing friction and making the movement smoother and more stable.

[0037] During the movement of the mobile platform mechanism 2, the operator can precisely control the moving distance and position of the platform seat 21 by adjusting the rotation speed and direction of the driving component 23. When the platform seat 21 moves to the designated position, the operator engages the pawl plate 28 with the ratchet teeth 14 on the outside of the base 11 by twisting the handle 29, and firmly locks the pawl plate 28 on the ratchet teeth 14 by the elastic force of the torque spring 27, thereby preventing the platform seat 21 from being displaced due to external factors such as vibration or impact.

[0038] Finally, when the boiler needs to be released, the operator again twists the handle 29 to separate the pawl plate 28 from the ratchet teeth 14 to release the locking state. Then, the driving component 23 is reversely operated to make the worm 22 and the worm wheel 24 rotate in the opposite direction, thereby driving the platform seat 21 to move in the opposite direction, and finally removing the boiler from the base 11.

[0039] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
