Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to an in-furnace support structure of a walking beam type heating furnace. Background Art

[0002] Walking beam heating furnace is a kind of equipment commonly used in industrial production for heating materials or processing industrial products. It is usually composed of furnace body, heating elements and supporting structure. In high temperature working environment, the design and performance of the supporting structure are crucial to the stable operation and safety of the equipment.

[0003] The shortcomings of the existing walking beam heating furnace's internal support structure:

[0004] Insufficient structural stability:

[0005] Traditional support structure designs may have problems with insufficient structural stability, especially under high temperature conditions. Due to factors such as thermal expansion, the entire furnace structure may easily become deformed and unstable, affecting the reliability of the equipment.

[0006] Poor load conduction effect:

[0007] Some existing designs are not effective in handling lateral loads and lack an effective load transfer mechanism, which can easily lead to structural stress concentration and affect the life of the supporting structure.

[0008] Insufficient overall stiffness:

[0009] The overall stiffness of some supporting structures in the lateral and longitudinal directions may be insufficient to effectively resist external shocks and vibrations, resulting in equipment vibration, noise and structural fatigue.

[0010] Therefore, this invention proposes a supporting structure in a walking beam type heating furnace to solve the above problems. Utility Model Content

[0011] In order to overcome the defects of the prior art, the utility model aims to provide a furnace support structure of a walking beam type heating furnace.

[0012] To achieve the above object, the technical solution of the utility model is implemented as follows: a walking beam type heating furnace in-furnace support structure, including a bottom support structure and a furnace top support structure, the bottom support structure has a plurality of laterally equidistantly distributed, and the furnace top support structure has a plurality of correspondingly installed between the tops of adjacent bottom support structures;

[0013] The bottom support structure comprises:

[0014] The arched support located above;

[0015] A vertical bracket correspondingly mounted at the front and rear bottom ends of the arched bracket;

[0016] The furnace top supporting structure comprises:

[0017] a transverse support assembly end fixture located directly above the arched support at the location;

[0018] Three lateral support assemblies docked at one side of the lateral support assembly end fixings;

[0019] The end fixing member of the lateral support assembly comprises:

[0020] A longitudinal support distributed directly above the arch support;

[0021] A central support and diagonal supports are installed between the longitudinal supports and the arch supports.

[0022] Preferably, the bottom end of the central pillar is welded to the top center of the arch support, and the top end of the central pillar is welded to the bottom center of the longitudinal support.

[0023] Preferably, the top end of the oblique support is welded to one end of the bottom of the longitudinal support, the bottom end of the oblique support is welded to the arch surface on the same side of the arch support, and the direction of the central axis of the oblique support is located in the radial direction of the contact point of the arch support.

[0024] Preferably, the lateral support assembly comprises:

[0025] A crossbeam distributed transversely between the longitudinal supports on both sides;

[0026] End fixing plates arranged at the left and right ends of the crossbeam;

[0027] The six butt bolts are evenly distributed on the end fixing plate, and the six butt bolts at one end are fixed correspondingly to the inside of the six bolt positioning holes where the longitudinal support butts the transverse support assembly.

[0028] Preferably, the bottom support structure further comprises:

[0029] A bottom support is installed at the bottom ends of the vertical brackets on both sides.

[0030] Preferably, the supporting structures are made of high-strength heat-resistant steel.

[0031] The beneficial effects of the utility model are embodied in:

[0032] Improved structural stability:

[0033] The combination of arch supports and vertical supports provides uniform support at the bottom, effectively dispersing the weight of the structure above and increasing the stability of the entire support structure.

[0034] The end fixings of the transverse support assembly are tightly fixed to the arch bracket, ensuring the stable support of the furnace top under high temperature conditions and avoiding the problems of furnace body deformation and structural instability.

[0035] Load spreading and conduction:

[0036] The design of the diagonal struts disperses the lateral load and effectively reduces the stress concentration of the structure.

[0037] The setting of the central pillar makes the longitudinal support more uniform, ensures the force balance between the upper and lower parts of the furnace body, and effectively transmits the pressure from above to the arch support, thereby improving the compressive resistance of the overall structure.

[0038] Overall rigidity enhancement:

[0039] By setting up the transverse support components, especially the transverse distribution of the crossbeams, the overall rigidity of the furnace roof is increased, and deformation and vibration of the furnace body caused by temperature changes are prevented.

[0040] The in-furnace support structure of the walking beam heating furnace has been cleverly designed to effectively improve the stability and overall performance of the structure. The rationally distributed support elements can not only evenly bear the weight and heat load of the furnace, but also ensure the safe operation of the furnace in a high temperature environment through a beneficial load conduction and dispersion mechanism. The choice of high-strength heat-resistant steel material further improves the durability of the support structure, providing reliable support for the long-term stable operation of the equipment.
