Description

Technical Field

[0001] This utility model belongs to the field of boiler steel structure technology, and specifically relates to a combined installation frame for a stable waste heat boiler steel structure. Background Technology

[0002] In the overall structure of a waste heat boiler, the installation frame is its physical core and foundation. It must not only bear the huge static load of the boiler body, but also the dynamic load during operation, as well as the thermal stress brought by the high temperature environment. Traditional steel structures are mostly fully welded on site. The welding quality is greatly affected by the environment and the skill level of the workers. Moreover, traditional full welding is a rigid connection. The operating conditions of waste heat boilers are complex. Frequent start-ups and shutdowns lead to thermal expansion and contraction, and the flow of flue gas may cause vibration. Rigid connection structures have poor absorption capacity for thermal stress and vibration. Long-term operation can easily lead to structural fatigue, loosening of connection points and other hidden dangers.

[0003] A search revealed that an auxiliary support device for a waste heat boiler steel structure, with prior art authorization announcement number CN223036376U, includes a boiler body and a support frame. This device suspends the boiler body by welding suspension plates to both sides and adjusts the height by setting steel columns on the bases on both sides. However, this device is welded and fixed, and the boiler vibrates during operation. The rigid connection structure has poor absorption capacity for thermal stress and vibration, and long-term operation can easily lead to structural fatigue, loosening of connection points, and other hidden dangers. Another search revealed that a boiler steel structure with an auxiliary support structure, with prior art authorization announcement number CN223306216U, includes a base frame with four support columns fixedly connected to the bottom. A support frame is fixedly connected between the tops of the four support columns. This device uses a first buffer pad in close contact with the bottom of the boiler body, allowing damping block shock absorbers to dampen the boiler body through the support sleeve. However, this device lacks a reinforcing structure between the support columns, resulting in not only longitudinal vibration but also lateral vibration during boiler operation. The support strength is relatively insufficient, posing a risk of boiler tipping over. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a stable steel structure combined installation frame for waste heat boilers. The strengthening mechanism ensures the overall stability of the structure, absorbs the vibration generated by the waste heat boiler, and improves the stability of the waste heat boiler during operation. The boiler fixing mechanism ensures the stable connection between the waste heat boiler and the steel structure frame and provides support for the waste heat boiler. The pipeline fixing mechanism pre-plans the pipeline routing to ensure the stability of the pipeline and further enhances the overall stability of the waste heat boiler. The multi-layer working platform ensures the maintenance and operation of the waste heat boiler and the steel structure as a whole.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A stable waste heat boiler steel structure modular installation frame includes a waste heat boiler, pipes, supporting columns, supporting beam I, pipe fixing mechanism, working platform, reinforcing mechanism, reinforcing rib I, supporting beam II, and boiler fixing mechanism. Multiple sets of supporting beam I, supporting beam II, and supporting columns are provided. Supporting beam I and supporting beam II are fixedly connected to form a rectangular structure. Supporting columns are located at the lower part of supporting beam II to provide support. Reinforcing rib I is provided at the overlap between supporting beam II and supporting column. The waste heat boiler is installed within the steel structure frame composed of supporting beam I, supporting beam II, and supporting columns. A boiler fixing mechanism is provided on the outside of the waste heat boiler to connect it to the steel structure frame. Pipes are located on one side of the waste heat boiler, and a pipe fixing mechanism is provided on the outside of the pipes for pipe fixing. The mechanism is located between supporting beam I and supporting beam II. Multiple reinforcing mechanisms are also located between supporting beam II. The working platform has multiple layers and is laid on supporting beams I and II. The working platform is equipped with protective railings and stairs. The supporting columns, supporting beams I and II form a steel structure frame. The reinforcing mechanism ensures the overall stability of the structure and absorbs vibrations generated by the waste heat boiler, improving its operational stability. The boiler fixing mechanism ensures a stable connection between the waste heat boiler and the overall steel structure frame, providing support for the waste heat boiler. The pipeline fixing mechanism pre-plans the pipeline routing, ensuring pipeline stability and further enhancing the overall stability of the waste heat boiler. The multi-layered working platform ensures personnel can maintain and operate both the waste heat boiler and the overall steel structure.

[0007] The pipe fixing mechanism includes a fixing ring, a fixing slider, fastening bolt I, and fastening bolt II. The fixing mechanism has multiple sets, with two sets of fixing rings. The two sets of fixing rings clamp the pipe together with fastening bolt II. A fixing slider is located on the other side of the fixing ring and is also positioned within a groove on the supporting beam II. The fixing slider is fastened to the supporting beam II using fastening bolt I. Through the combination of the fixing ring and the fixing slider, the pipe can be fixed to the steel structure frame, ensuring stable operation and laying of the pipe.

[0008] The boiler fixing mechanism includes a fixing plate, stiffening ribs, and fastening bolts III. The fixing plate is installed around the preheating boiler by fastening bolts III. The stiffening ribs are fixed to the fixing plate and simultaneously match the size of the slots on the supporting beams I and II. The stiffening ribs are set in the slots on the supporting beams I and II. The entire boiler fixing mechanism is set within the rectangular frame formed by the supporting beams I and II. By setting the stiffening ribs in the slots on the supporting beams I and II, the connection between the waste heat boiler and the steel structure frame is ensured, thus ensuring the stability of the waste heat boiler during operation.

[0009] The strengthening mechanism includes reinforcing rib II, connecting seat I, reinforcing column I, connecting seat II, reinforcing column II, connecting seat III, buffer mechanism, reinforcing column III, and fastening bolt IV. Two sets of reinforcing rib II are located at the overlap between the supporting beam II and the supporting column. Connecting seat I is located on reinforcing rib II. Reinforcing column I is located within connecting seat I and rotatably connected to it. Connecting seat II is located on reinforcing column I. One end of reinforcing column II is located within connecting seat II and rotatably connected to it, while the other end is located within connecting seat III and rotatably connected to it. Connecting seat III is fixed to the supporting beam II by fastening bolt IV. The two sets of reinforcing columns I are connected by reinforcing column III. A buffer mechanism is located at the lower end of reinforcing column III and is also located on the supporting beam II. The strengthening mechanism further consolidates the stability of the steel structure frame formed by the supporting beam I, supporting beam II, and supporting column, while the buffer mechanism reduces vibration during the operation of the waste heat boiler.

[0010] The buffer mechanism includes a positioning plate, a damping block, a spring, and a fastening bolt V. The positioning plate is fixed to the supporting beam II by the fastening bolt V. The damping block is set on the positioning plate and at the lower end of the reinforcing column III. The spring is sleeved on the damping block and is also set between the reinforcing column III and the positioning plate. The shock-absorbing buffer structure formed by the spring and the damping block absorbs the vibration generated during the operation of the waste heat boiler, thereby improving the working stability of the waste heat boiler.

[0011] The advantages of this utility model compared with the prior art are as follows:

[0012] The boiler fixing mechanism ensures the connection between the waste heat boiler and the steel structure frame, providing support for the waste heat boiler and guaranteeing its stability during operation. The reinforcing mechanism integrates multiple sets of supporting columns, supporting beam I, and supporting beam II, forming a collaborative force-bearing system and increasing the overall stability of the steel structure frame. By incorporating a buffer mechanism within the reinforcing mechanism, the vibrations generated by the waste heat boiler during operation are effectively absorbed, preventing structural fatigue and loosening of connection points caused by long-term vibration. The pipe fixing mechanism also provides support for the external pipes of the waste heat boiler, further enhancing the overall structural stability. Attached Figure Description
