The following is an explanation of the embodiments of the utility model based on its overall structure.

[0020] The specific implementation of the utility model is as follows:

[0021] The utility model:

[0022] like Figure 1-Figure 2 As shown, a disassembly and assembly tool for a combustion furnace of an airflow wire drying machine comprises two front columns 1 arranged in parallel and two rear columns 2 arranged in parallel, wherein the height of the rear columns 2 is greater than that of the front columns 1, a first cross beam 3 is arranged between the two front columns 1, a second cross beam 4 is connected between the two rear columns 2, a longitudinal beam 5 is arranged between the bottom of the front column 1 and the bottom of the rear column 2 on the same side, a diagonal bracing beam 6 is arranged between the top of the front column 1 and the top of the rear column 2 on the same side, the top surfaces of the two diagonal bracing beams 6 can abut against the oblique end surfaces of the combustion furnace connecting flange, and the diagonal bracing beams 6 are provided with positioning holes 7 which can be adapted to the connecting bolts on both sides of the combustion furnace connecting flange.

[0023] In the present disassembly and assembly tool of the combustion furnace of the airflow wire drying machine, two front columns 1, two rear columns 2, a first crossbeam 3, a second crossbeam 4 and two diagonal bracing beams 6 form a frame with a central hole, the frame can be sleeved on the outside of the combustion furnace of the airflow wire drying machine, and the combustion furnace and other structures are accommodated inside the frame, and then the two diagonal bracing beams 6 are abutted against the oblique end faces of the combustion furnace connecting flange, and then the positioning holes 7 on the diagonal bracing beams 6 are matched with the bolts on both sides of the combustion furnace connecting flange, and the combustion furnace connecting flange and the diagonal bracing beams 6 are fixed by nuts, so that the present tool supports the combustion furnace connecting flange, thereby facilitating the connection of the combustion furnace The flange is removed from between the combustion furnace and the large fan, or the combustion furnace is installed on the large fan. The gas flow wire drying machine combustion furnace disassembly and assembly tool can quickly and conveniently connect with the bolts on the combustion furnace connecting flange, so that the two diagonal support beams 6 support the flange, thereby facilitating the maintenance staff to disassemble and assemble the flange, with high work efficiency, simple operation, and guaranteed work safety, avoiding the problems of flange shaking and injuring people, falling and hitting people, inconvenience in screw hole alignment, harsh high-altitude working environment on the grille, stuffiness, and tool falling and injuring people when the flange is hoisted on the grille in the prior art.

[0024] In this embodiment, the positioning hole 7 is a waist-shaped hole structure, and the positioning hole 7 is set as a waist-shaped hole structure to facilitate docking with the bolts on the flange.

[0025] In this embodiment, there are two first cross beams 3, and the two first cross beams 3 are respectively connected to the bottom and the top of the two front pillars 1. The two first cross beams 3 support the two front pillars 1 to ensure the firmness and stability of the entire tooling.

[0026] In this embodiment, a liftable stopper 8 is provided in the middle of the first cross beam 3 located at the top of the two front columns 1, and an arc-shaped groove 13 is provided on the stopper 8. After the positioning holes 7 on the diagonal support beam 6 are connected with the bolts on the flange, the stopper 8 can be lifted so that the stopper 8 abuts against the bottom surface of the flange to provide auxiliary support for the flange, thereby reducing the tangential force on the bolts caused by the gravity of the flange and preventing the bolts from bending.

[0027] In this embodiment, guide rods 9 slidingly connected to the first crossbeam 3 are provided on both sides of the stopper 8, and guide holes matching the guide rods 9 are provided on the first crossbeam 3. A lifting screw 10 threadedly connected to the first crossbeam 3 is provided in the middle of the stopper 8 through a bearing. The lifting screw 10 rotates forward or reversely to drive the stopper 8 to rise or fall, and adjust the height of the stopper 8 so that the arc groove 13 on the stopper 8 can abut against the bottom of the flange to support the bottom of the flange.

[0028] In this embodiment, there are two second cross beams 4, and the two second cross beams 4 are respectively connected to the bottom and the top of the two rear pillars 2. The two second cross beams 4 support the two rear pillars 2 to ensure the firmness and stability of the entire tooling.

[0029] In this embodiment, slots 11 are provided on both sides of the second cross beam 4 at the bottom of the two rear columns 2 and on both sides of the first cross beam 3 at the bottom of the two front columns 1. The slots 11 can allow the forklift arm of a forklift to pass through, and the slots 11 can be slidably connected to the forklift arm. During the process of using a forklift to transport and lift the disassembly and assembly tooling of the airflow silk drying machine combustion furnace, the slots 11 can limit the forklift arm to prevent the forklift arm from separating from the tooling, thereby ensuring the safety of the transport operation.

[0030] In this embodiment, a clamping screw 12 is provided on the top arm of the slot 11, and the slot 11 is a channel steel structure. The slot 11 is fixed to the first beam 3 and the second beam 4 by welding. The clamping screw 12 is threadedly connected to the first beam 3 and the second beam 4, and passes through the top arm of the slot 11. After the forklift arm of the forklift is inserted into the slot 11, the forklift arm can be clamped by tightening the clamping screw 12 to prevent relative sliding between the forklift arm and the slot 11 when transporting the tooling.

[0031] Working principle:

[0032] When disassembling, use the forklift arm of a forklift to insert into the slot 11 at the bottom of the tooling, and then fix it by tightening the screw 12;

[0033] Next, the forklift arm of the forklift lifts the tooling, so that the combustion furnace is inserted into the cavity between the two diagonal bracing beams 6. The two diagonal bracing beams 6 are adapted to the rear end surface of the flange of the combustion furnace. The position of the tooling is adjusted so that the bolts on both sides of the flange are plugged into the positioning holes 7 on the diagonal bracing beams 6. Then, the flange and the diagonal bracing beams 6 are fixed by nuts. At the same time, the position of the stopper 8 is adjusted by the lifting screw 10 so that the stopper 8 supports the bottom of the flange.

[0034] Then, with the support of the burner flange by this tooling, the staff can remove the burner flange from the large fan flange, and then operate a forklift to move the burner and the burner flange to the designated location.
