Auxiliary support structure of a dust removal pneumatic ash conveying system of a boiler

Abstract

This utility model provides an auxiliary support structure for a boiler dust removal pneumatic ash conveying system, relating to the field of boiler pipe installation technology. The auxiliary support structure includes a support base plate, a lifting assembly fixedly mounted on the top of the support base plate, a support assembly fixedly mounted on the top of the lifting assembly, and symmetrically arranged limiting components fixedly mounted on the top of the support assembly. In this auxiliary support structure, the pipe is positioned between two limiting plates inside the connecting seat. The weight of the pipe acts on the limiting plates through a rotating roller, pressing down on the limiting plates to rotate them along their hinged position with the connecting seat. This causes the guide rod to slide, bringing the limiting plates closer to the support assembly and squeezing a return spring, changing the included angle between the inner sides of the two limiting plates. This allows for adaptive adjustment to the pipe diameter, enabling better support and auxiliary installation of boiler pipes of different diameters and reducing limitations.

Description

Technical Field

[0001] This utility model relates to pipeline installation equipment in a boiler pneumatic ash conveying system, specifically an auxiliary support structure for a boiler dust removal pneumatic ash conveying system, belonging to the field of boiler pipeline installation technology. Background Technology

[0002] The boiler dust removal pneumatic ash conveying system is a system that uses compressed air or negative pressure airflow as power to transport dust or ash generated by boiler dust removal from the collection device to the ash silo through a closed pipeline. It features high efficiency, energy saving and environmental protection. The dust needs to be transported through the conveying pipeline, and the pipeline installation process requires auxiliary support devices to support the pipeline, adjust the height and connect the installation.

[0003] Existing patent application number CN219367590U discloses an auxiliary fixing device for boiler pipes. By connecting the arc-shaped bracket at the top of the adjusting rod with the pipe to be installed, the pipe can be effectively supported, avoiding the need for the operator to support the pipe during installation. In conjunction with the multiple sets of rotating rollers inside the arc-shaped bracket, it is convenient for the operator to adjust the angle of the boiler pipe during installation.

[0004] In the aforementioned patent, the pipe is supported by an arc-shaped bracket, and the pipe can be adjusted by contacting the inner roller of the arc-shaped bracket. However, the curvature of the arc-shaped bracket is fixed, which cannot guarantee a perfect fit with the size of the pipe. When a smaller diameter pipe is placed, it cannot effectively limit the lateral movement of the pipe, which can easily cause shaking and make docking difficult. When a larger diameter pipe is placed, it cannot guarantee that the outer wall of the pipe will contact the roller, making adjustment inconvenient and lacking flexibility. In addition, it only supports the pipe with a single arc-shaped bracket, which has only a single point of force. When the pipe is long, the overall stability is poor. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this utility model is to provide an auxiliary support structure for a boiler dust removal pneumatic ash conveying system in order to solve the above-mentioned problems. This structure addresses the limitations of existing technologies where the arc-shaped bracket has a fixed curvature, cannot fully adapt to the pipe size, is inconvenient to make adaptive adjustments, is not flexible enough, and has certain limitations. Furthermore, supporting the pipe with a single arc-shaped bracket only has a single stress point, resulting in poor overall stability when the pipe is long.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: an auxiliary support structure for a boiler dust removal pneumatic ash conveying system.

[0009] The system includes a supporting base plate, a lifting assembly fixedly mounted on the top of the supporting base plate, a supporting assembly fixedly mounted on the top of the lifting assembly, and symmetrically arranged limiting components fixedly mounted on the top of the supporting assembly. Each limiting component includes a connecting seat fixedly mounted on the top of the supporting assembly. Two symmetrically arranged limiting plates are hinged to the inner side of the connecting seat. Each limiting plate has a groove on its top, and a rotating roller is rotatably mounted inside the groove. A guide rod is fixedly connected to the bottom of each limiting plate, penetrating the interior of the supporting assembly. A return spring is movably sleeved on the outside of the guide rod, located between the limiting plate and the supporting assembly.

[0010] Preferably, the two limiting plates are arranged in a "V" shape inside the connecting seat, which can provide stable support for pipes of different diameters.

[0011] Preferably, multiple rotating rollers are equidistantly arranged within the groove, and the pipe can be rotated and adjusted around its axis by contacting the outer wall of the pipe.

[0012] Preferably, the guide rod is arc-shaped, the support assembly has a groove inside that corresponds to the guide rod, and a limiting piece located below the support assembly is fixedly installed at the bottom of the guide rod, which can effectively limit the direction and range of movement of the guide rod.

[0013] Preferably, the lifting assembly includes a guide frame fixedly installed on the top of the support base plate, a lifting screw rotatably installed inside the guide frame, a lifting block threadedly connected to the outside of the lifting screw, a support column fixedly connected to the top of the lifting block, the support column being engaged between the guide frame and the lifting screw, a worm gear fixedly installed below the outside of the lifting screw, and a worm gear meshing with the worm gear rotatably installed below the inside of the guide frame, allowing for flexible adjustment of the support position height to adapt to different pipe connection situations.

[0014] Preferably, the support assembly includes a support top plate, a first connecting block, and a second connecting block. The support top plate is fixedly installed on the top of the support column. The first connecting block is fixedly connected to the bottom of the support top plate. The second connecting block is fixedly connected to the left and right sides of the support column. The first connecting block and the second connecting block are symmetrically arranged. A diagonal brace is movably hinged between the first connecting block and the second connecting block on the same side, which enhances the load-bearing capacity and improves the stability of the support.

[0015] Preferably, the left and right sides of the guide frame are provided with straight slots that are the same width as the docking block two and extend through the top of the guide frame, which can effectively guide the movement direction of the docking block two.

[0016] This utility model provides an auxiliary support structure for a boiler dust removal pneumatic ash conveying system, which has the following beneficial effects:

[0017] 1. The pipe is placed between the two limiting plates inside the connecting seat. The weight of the pipe acts on the limiting plates through the rotating roller, pressing down on the limiting plates so that they rotate along the hinge position with the connecting seat, driving the guide rod to slide, so that the limiting plates are close to the support assembly and squeeze the return spring, changing the included angle between the inner sides of the two limiting plates, so that they can adaptively adjust with the pipe diameter, which can better support and assist the installation of boiler pipes of different diameters and reduce limitations.

[0018] 2. By installing diagonal braces between docking blocks one and two on the same side, the diagonal braces form a triangular structure between docking blocks one and two, and between the supporting top plate and the supporting column. Combined with the symmetrical arrangement above the supporting top plate, this provides support points for the pipeline at different positions, effectively improving the stability of the support.

[0026] This utility model provides an auxiliary support structure for a boiler dust removal pneumatic ash conveying system.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The system includes a support base plate 1, a lifting assembly 2 fixedly mounted on the top of the support base plate 1, a support assembly 3 fixedly mounted on the top of the lifting assembly 2, and symmetrically arranged limiting assemblies 4 fixedly mounted on the top of the support assembly 3. Each limiting assembly 4 includes a connecting seat 41 fixedly mounted on the top of the support assembly 3. Two symmetrically arranged limiting plates 42 are hinged to the inner side of the connecting seat 41. Each limiting plate 42 has a groove 43 on its top, and a rotating roller 44 is rotatably mounted inside the groove 43. The bottom of each limiting plate 42... Each component is fixedly connected with a guide rod 45, which penetrates the interior of the support assembly 3. A reset spring 46 is movably sleeved on the outside of the guide rod 45 between the limiting plate 42 and the support assembly 3. The two limiting plates 42 are arranged in a "V" shape inside the connecting seat 41. Multiple rotating rollers 44 are arranged at equal intervals in the groove 43. The guide rod 45 is arc-shaped. The interior of the support assembly 3 has a sliding groove corresponding to the guide rod 45. A limiting piece 47 located below the support assembly 3 is fixedly installed at the bottom of the guide rod 45.

[0028] In use, this utility model involves placing the pipe to be installed between two symmetrically arranged limiting plates 42 hinged together on the inner side of the connecting seat 41. The outer wall of the pipe contacts the rotating roller 44 located inside the limiting plate 42. Due to the weight of the pipe, the weight of the pipe acts on the limiting plate 42 through the rotating roller 44, thus pressing down the limiting plate 42 and causing it to rotate at the hinged position with the connecting seat 41. The rotation of the limiting plate 42 drives the guide rod 45 to slide within the support assembly 3, bringing the limiting plate 42 closer to the support assembly 3 and squeezing the return spring 46. The rotation of the two limiting plates 42 changes their inner angle, thus widening the opening. The elastic force of the return spring 46 pushes the limiting plate 42 to rotate and reset at the hinged position of the connecting seat 41. This provides stable support for pipes of different diameters.

[0029] The two limiting plates 42 are designed in a "V" shape, which allows the limiting plates 42 to better adapt to the support and limiting requirements of boiler pipes of different diameters. The opening angle between the two limiting plates 42 does not exceed 180 degrees, which prevents the pipe from rolling down from the top to the side. When the pipe is placed between the limiting plates 42, the two limiting plates 42 will automatically adjust the angle according to the shape of the object to ensure its stability. The "V" shape structure can also effectively disperse the pressure of the pipe on the limiting plates 42.

[0030] The surfaces of multiple rotating rollers 44 are all smoothed, and rubber sleeves are provided on the outside of multiple rotating rollers 44 to increase the friction with the pipe and facilitate the rotation of the pipe for adjustment. The two ends of the rotating rollers 44 are connected to the inner wall of the groove 43 through bearings to ensure that they can rotate flexibly and effectively improve the stability and reliability of the limiting component 4 during use.

[0031] The size of the limiting plate 47 is larger than that of the guide rod 45 to ensure that it can effectively prevent the guide rod 45 from disengaging from the support assembly 3. The elastic coefficient of the return spring 46 is calculated to provide appropriate rebound force when the limiting plate 42 is subjected to force, thereby ensuring the flexibility and reliability of the limiting assembly 4 during operation.

[0032] Please refer to it again. Figure 1 and Figure 4 The lifting assembly 2 includes a guide frame 21 fixedly installed on the top of the support base plate 1. A lifting screw 22 is rotatably installed inside the guide frame 21. A lifting block 23 is threadedly connected to the outside of the lifting screw 22. A support column 24 is fixedly connected to the top of the lifting block 23. The support column 24 is locked between the guide frame 21 and the lifting screw 22. A worm gear 25 is fixedly installed on the lower outside of the lifting screw 22. A worm 26 that meshes with the worm gear 25 is rotatably installed on the lower inside of the guide frame 21.

[0033] In use, this utility model allows the worm gear 26 to rotate by operating the rotating wheel located outside the guide frame 21 at its end. The worm gear 26 meshes with the worm wheel 25, causing the worm wheel 25 to rotate. The rotation of the worm wheel 25 synchronously drives the lifting screw 22 to rotate. The lifting block 23 is threadedly connected to the outside of the lifting screw 22. As the lifting screw 22 rotates, the lifting block 23 slides up and down along the outside of the lifting screw 22. The lifting block 23 pushes the support column 24 to move up and down within the guide frame 21, allowing for flexible adjustment of the height of the support component 3 above the support column 24. This, in turn, allows for adjustment of the pipe height to accommodate different installation and docking heights.

[0034] Please refer to it again. Figure 4 and Figure 5 The support assembly 3 includes a support top plate 31, a first connecting block 32, and a second connecting block 33. The support top plate 31 is fixedly installed on the top of the support column 24. The first connecting block 32 is fixedly connected to the bottom of the support top plate 31. The second connecting block 33 is fixedly connected to the left and right sides of the support column 24. The first connecting block 32 and the second connecting block 33 are symmetrically arranged on the left and right sides. A diagonal brace 34 is movably hinged between the first connecting block 32 and the second connecting block 33 on the same side. The left and right sides of the guide frame 21 are provided with straight slots with the same width as the second connecting block 33 and penetrating the top of the guide frame 21.

[0035] In use, this utility model is as follows: the first connecting block 32 and the second connecting block 33 are welded and fixed to the top support plate 31 and the support column 24 respectively. Then, the diagonal brace 34 is inserted between the first connecting block 32 and the second connecting block 33 on the same side and fixed by a pin. The diagonal brace 34 forms a triangular structure between the first connecting block 32 and the second connecting block 33 and between the top support plate 31 and the support column 24, providing stable support.

[0036] With the design of the straight slot, the second docking block 33 can move longitudinally within the guide frame 21, thereby ensuring the normal use of the support column 24 during the lifting process. The width of the straight slot matches the second docking block 33, avoiding the shaking problem caused by excessive gap, effectively limiting the movement range of the second docking block 33, and preventing it from deviating from the predetermined trajectory.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
