[0027] like Figure 1 As shown, an industrial boiler door disassembly and assembly device includes: a support portion 1, a main rod 2 movably provided at one end of the support portion 1, and a moving mechanism 3 provided at the other end of the support portion 1; wherein one end of the main rod 2 is an operating end 201, and the other end is an execution end 202. The operating end 201 moves with the connection between the main rod 2 and the support portion 1 as a fulcrum, and the execution end 202 moves in the opposite direction with the operating end 201. Specifically:

[0028] like Figure 2 As shown, the support portion 1 includes a support rod 101, a connecting seat 102 hinged to the main rod 2, and a first adjusting portion 103 provided between the support rod 101 and the connecting seat 102. The first adjusting portion 103 includes a first sleeve 1031. The top end of the first sleeve 1031 is rotatably connected to the bottom of the connecting seat 102. The bottom end of the first sleeve 1031 is sleeved on the support rod 101 and threadedly connected to the support rod 101. The first adjusting portion 103 is used to adjust the height of the connecting seat 102, thereby adjusting the height of the main rod 2, which facilitates disassembly and assembly according to the position of the furnace door at different heights, thereby improving applicability.

[0029] The mobile mechanism 3 includes a base 301 and universal wheels 302 installed on both sides of the base 301. The top of the base 301 is fixedly connected to the support rod 101.

[0030] The execution end 202 is provided with a clamping mechanism 4, which includes a plurality of hooks 401 matching the furnace door handle and a positioning portion 402 for holding the furnace door. Specifically:

[0031] It should be noted that in this example, the industrial boiler is a German LOOS brand, model ZFR-23000, and has two furnace door handles. The number of hooks 401 is two, and the two hooks 401 and the positioning portion 402 are evenly distributed on the execution end 202. The hooks 401 are fixedly connected to the execution end 202;

[0032] The positioning portion 402 includes a positioning rod 4021 fixed to the execution end 202, an extension rod 4022 for supporting the furnace door, and a second adjustment portion 4023 arranged between the positioning rod 4021 and the extension rod 4022; wherein, the second adjustment portion 4023 includes a second sleeve 40231; one end of the second sleeve 40231 is rotatably connected to the extension rod 4022, and the other end is sleeved on the positioning rod 4021 and threadedly connected to the positioning rod 4021; the second adjustment portion 4023 is used to adjust the length of the extension rod 4022, so as to fine-tune the supporting distance of the extension rod 4022 to the furnace door, ensuring that the furnace door is overall level before moving out.

[0033] In this example, the length from the operating end 201 to the fulcrum is not less than the length from the execution end 202 to the fulcrum, and the operating end 201 is movably sleeved with an extension rod 5 for increasing the length of the operating end 201. Specifically:

[0034] The main rod 2 is hollow inside, and the inner circumference of the operating end 201 is provided with an internal thread. The outer circumference of the extension rod 5 is provided with an external thread matching the internal thread at the operating end 201. The extension rod 5 is threadedly connected to the main rod 2;

[0035] Rotating the extension rod 5 can extend a portion of the extension rod 5 out of the main rod 2. By utilizing the lever principle, the force required to lift the furnace door can be reduced, reducing the work intensity, and also avoiding the situation where the operator is physically exhausted during the process of moving the furnace door, causing the main rod 2 to shake, and eventually causing the furnace door to bump into something. Example

[0036] like Figure 3 As shown, an industrial boiler door disassembly and assembly device includes: a support portion 1, a main rod 2 movably provided at one end of the support portion 1, and a moving mechanism 3 provided at the other end of the support portion 1; wherein one end of the main rod 2 is an operating end 201, and the other end is an execution end 202. The operating end 201 moves with the connection between the main rod 2 and the support portion 1 as a fulcrum, and the execution end 202 moves in the opposite direction with the operating end 201. Specifically:

[0037] like Figure 4 As shown, the support portion 1 includes a support rod 101, a connecting seat 102 hinged to the main rod 2, and a first adjustment portion 103 provided between the support rod 101 and the connecting seat 102. The first adjustment portion 103 includes a first sleeve 1031. The top end of the first sleeve 1031 is rotatably connected to the bottom of the connecting seat 102. The bottom end of the first sleeve 1031 is sleeved on the support rod 101 and is threadedly connected to the support rod 101.

[0038] The first adjusting portion 103 is used to adjust the height of the connecting seat 102, thereby adjusting the height of the main rod 2, so as to facilitate disassembly and assembly according to positions of furnace doors at different heights, thereby improving applicability;

[0039] The mobile mechanism 3 includes a base 301 and universal wheels 302 installed on both sides of the base 301. The top of the base 301 is fixedly connected to the support rod 101.

[0040] The execution end 202 is provided with a clamping mechanism 4, which includes a plurality of hooks 401 matching the furnace door handle and a positioning portion 402 for holding the furnace door. Specifically:

[0041] It should be noted that in this example, the industrial boiler is a German LOOS brand, model ZFR-23000, and has two furnace door handles. The number of hooks 401 is two, and the two hooks 401 and the positioning portion 402 are evenly distributed on the execution end 202. The hooks 401 are fixedly connected to the execution end 202;

[0042] The positioning portion 402 includes a positioning rod 4021 fixedly connected to the actuator end 202, an extension rod 4022 for supporting the furnace door, and a second adjustment portion 4023 disposed between the positioning rod 4021 and the extension rod 4022. The second adjustment portion 4023 includes a second sleeve 40231. One end of the second sleeve 40231 is rotatably connected to the extension rod 4022, and the other end is sleeved on the positioning rod 4021 and threadedly connected to the positioning rod 4021.

[0043] The second adjusting portion 4023 is used to adjust the length of the extension rod 4022 , thereby fine-tuning the distance between the extension rod 4022 and the furnace door, ensuring that the furnace door is overall level before being moved out.

[0044] In this example, the length from the operating end 201 to the fulcrum is not less than the length from the execution end 202 to the fulcrum, and the operating end 201 is movably sleeved with an extension rod 5 for increasing the length of the operating end 201. Specifically:

[0045] The main rod 2 is hollow inside, and a slide groove 6 is provided inside the operating end 201. A slider 7 matching the slide groove 6 is fixed to the outside of the extension rod 5. The extension rod 5 is slidably connected to the main rod 2.

[0046] Pulling the extension rod 5 can extend a portion of the extension rod 5 out of the main rod 2. By utilizing the lever principle, the force required to lift the furnace door can be reduced, reducing the work intensity, and also avoiding the situation where the operator is physically exhausted during the process of moving the furnace door, causing the main rod 2 to shake, and eventually causing the furnace door to bump into something.

[0047] How it works

[0048] The operator extends the extension rod 5 out of the main rod 2 and pushes the main rod 2. The main rod 2 moves under the action of the moving mechanism 3 and rotates the first sleeve 1031 according to the position of the furnace door to adjust the height of the connecting seat 102 so that the axis of the execution end 202 of the main rod 2 is located at the center of the furnace door. The claw 401 at the execution end 202 of the main rod 2 is hooked on the handle of the furnace door. By pressing the extension rod 5 at the operating end 201 of the main rod 2, the execution end 202 of the main rod 2 is lifted upward, and the main rod 2 is executed. When the end 202 is lifted, the furnace door is lifted slightly at the same time through the hook claw 401, and after the furnace door is lifted, the second sleeve 40231 is rotated to fine-tune the length of the extension rod 4022 to support the furnace door. After the furnace door is stable, observe whether there is any scratch between the furnace door and the inner and outer edges of the furnace body. If there is any scratch, continue to rotate the second sleeve 40231 to fine-tune the length of the extension rod 4022 until there is no scratch between the furnace door and the inner and outer edges of the furnace body. Then you can pull the main rod 2 outward, and the moving mechanism 3 drives the main rod 2 and the furnace door to move stably through the support part 1.
