Problems solved by technology
[0003] Usually, heavy, large, high, and special-shaped structural objects are transported by self-propelled hydraulic flatbed trucks, but there are certain difficulties in using self-propelled hydraulic flatbed trucks to lift and transport the supporting frame of the entire radial section, and the stability during transportation cannot be guaranteed. Due to the limitation of the support frame structure of the overall radiant section, the self-propelled hydraulic flatbed truck cannot enter the bottom of the radiant section of the steam reformer to lift the support frame of the radiant section for transportation, making the transportation of the support frame of the radiant section a difficult problem

Embodiment Construction
[0017] Example image 3 As shown, the method for modular transport of the support frame of the radiant section of the steam reformer of the present invention includes the following steps:
[0018] Step 1. Install bolted crossbeams 13 between the steel spans 11 and 12 of the support structure 1 at the lower part of the support frame of the radiation section, so that the self-propelled hydraulic flatbed can lift the support frame of the radiation section when it enters the bottom of the support frame of the radiation section. For transportation, a vertical beam 14 is installed between the middle of the crossbeam 13 and the furnace floor 3 to meet the overall strength of the supporting frame of the radiation section during transportation, and the crossbeam 13 and the vertical beam 14 constitute a transportation structure;
[0019] Step 2. Temporarily change the double column support of the lower support structure 1 separated by the steel span 12 to a single column 15 support to m...

The invention discloses a method for modular transportation of a radiant section support frame of a steam reformer. The method is characterized in that a connecting beam is arranged between each steel-structured cross member of a lower support structure of the radiant section support frame, and vertical beams are arranged between the beam and a furnace base plate, so as to form a transportation structure; the steel-structured cross members supported by double column are temporarily changed into the steel-structured cross members supported by single column support, so as to meet the width of aself-propelled hydraulic flat car into the lower support structure; the self-propelled hydraulic flat car enters the bottom of one module of the radiant section support frame, and after the self-propelled hydraulic flat car is in place, the self-propelled hydraulic flat car jacks the lower support structure to separate two modules, and then the modules are dropped on the self-propelled hydraulic flat car, and normally the modules are translated and transported; and after the modules are transported in place, the self-propelled hydraulic flat car slows discharges until the columns of the lowersupport structure are located on the ground foundation. The method for modular transportation of a radiant section support frame of a steam reformer overcomes the defects of transportation of the radiant section support frame, realizes the overall transportation of the radiant section support frame module, ensures the stability and safety of the transportation process, and improves the transportation efficiency.
Description
technical field [0001] The invention relates to a method for modularized transportation of a support frame of a radiant section of a steam reformer. Background technique [0002] The supporting frame of the radiant section of the steam reformer and the roof form an integrated structure after installation. The supporting frame of the radiant section and the roof structure are assembled on the ground respectively. The supporting frame of the radiant section is composed of two modules each weighing 1137 tons. Such as figure 1 shown. The support frame of the radiant section is an ultra-wide and super-high piece as a whole, and the center of gravity is not in the middle, but leans to one side. The overall support frame of the radiant section consists of the lower support frame 1, the first platform and railing 2, the furnace floor 3, and the second floor from bottom to top. The second floor platform and railing 4, the furnace wall panel 5, the third floor platform and railing 6...
