Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to an auxiliary support frame of a waste heat boiler steel structure. Background Art

[0002] During the traditional installation of waste heat boilers, a steel support frame is generally used to support the installation of the waste heat boiler. The traditional steel support frame uses rigid connections and lacks shock-absorbing and buffering devices. The waste heat boiler will produce irregular vibrations during use. Irregular vibrations will cause metal fatigue in the connectors, reduce the structural strength between the connectors, increase the maintenance cost of the steel support frame, and affect the overall stability of the steel support frame.

[0003] After searching, the prior art authorization announcement number CN 211804605 U is a vertical power station boiler steel structure support frame, which includes columns, beams, connecting mechanisms, horizontal support beams, clamp beams, vertical support beams, pre-fixed adjustment mechanisms, stairs, guardrails, and pedals. The two ends of the beams are fixedly connected to the columns; the connecting mechanisms and pre-fixed adjustment mechanisms are fixed to the columns; the clamp beams are fixed around the vertical boiler by bolts and are provided with multiple layers above and below; the vertical support beams are fixedly connected to the clamp beams of each layer; one end of the horizontal support beam is movably connected to the connecting mechanism, and the other end is fixedly connected to the clamp beam; the stairs are fixed to the outside of the columns; the guardrails are fixedly connected to the columns and the beams; the pedals are fixedly connected to the beams, clamp beams and horizontal support beams; the device can adjust the connection position of the corresponding steel structure and assist in fixing the position of the vertical boiler during the welding of the vertical boiler steel structure support frame, but lacks a corresponding buffering and shock-absorbing structure to buffer the vibration of the support mechanism or bracket, which easily causes support fatigue of the connection structure and reduces the stability of the structure.

[0004] After searching, the prior art authorization announcement number CN 220818095 U discloses a steel structure for a stable boiler steel frame, comprising a boiler body, a base, a support steel frame, and a steel beam seat. Support steel frames are mounted on both front and rear sides of the upper end of the base, and an adjustment mechanism is installed in each mounting hole. A limiting groove is excavated in the middle of the upper end of the base. An upper fixing frame of the same specification is provided above the support steel frame. Soft padded plates of the same specification are attached to the inner sides of the upper fixing frame and the support steel frame where they contact the boiler body. The steel beam seat is mounted on the upper ends of first and second diagonal bars, and the first and second diagonal bars are respectively mounted in the limiting grooves. The first and second diagonal bars intersect with each other and a rotating shaft is inserted in the middle. Shock-absorbing springs and damping rods are installed at the left and right open positions of the first and second diagonal bars. The mechanism achieves the purpose of making the steel beam seat more stable by providing shock-absorbing springs, elastic plates, and damping rods. The shock-absorbing springs and damping rods are both located at the lower part of the boiler and can only reduce the longitudinal vibration generated during boiler operation. The generated lateral vibration also affects the stability of the entire structure. Summary of the Invention
