[0002] Coking is a common problem in boiler operation. It will disrupt normal combustion conditions, reduce boiler steam output, disrupt normal water circulation, and cause pipe bursts. In severe cases, it will block the furnace cavity outlet and force the furnace to shut down. The front and rear arches of the waste power plant incinerator are seriously coked at a height of about 18 meters. The general way to clean coke in the waste power plant is to set up scaffolding above the grate at a height of about 13 meters and clean the coke from bottom to top.

[0003] At present, in the process of cleaning the coke blocks in the incinerator, the front and rear arch channels of the boiler are blocked by coke blocks due to severe coking, making the traditional method of setting up scaffolding to clean the coke from bottom to top no longer applicable. In addition, in the process of cleaning the coke from bottom to top, the coke blocks falling down are easy to affect the workers, which is less safe, thus slowing down the cleaning efficiency of the coke blocks in the incinerator, which is not conducive to the cleaning of the coke blocks in the incinerator. Therefore, it is urgent to improve the technology of the climbing structure for cleaning the coke blocks in the incinerator to improve this equipment.

[0004] Therefore, the utility model provides a fast ladder climbing device for cleaning the coke chamber of a garbage power plant. Utility Model Content

[0028] During the use of this scheme, during the coke block cleaning process of the incinerator, the entire ladder device is placed from the 23-meter inspection hole 7 to the 18-meter coking position, and then the furnace external fixing mechanism 4 drives a pair of ladder brackets 1 to connect with the 23-meter inspection hole external fixing point, and at the same time, the extension clamping mechanism 5 is extended to contact with the inner wall of the 23-meter inspection hole 7, and squeezed and clamped to strengthen the firmness of the connection to ensure that the ladder does not fall, and then the furnace ladder angle support mechanism 6 drives a pair of ladder brackets 1 to support on both sides on the front and rear arch walls 8 to ensure that the ladder is stable and does not shake, thereby stably installing the ladder device, prompting the staff to use the ladder to pass through and realize the coke cleaning work from top to bottom, ensuring that the coke blocks do not harm the staff during the downward falling process, and compared with the erection of scaffolding, the rapid ladder device is fast to install and is firm and stable, which effectively improves work efficiency.

[0029] See also Figure 1-3The external fixing mechanism 4 of the furnace includes a plurality of high-strength fixing bolts 401 threadedly connected to the mounting plate 3, the outer ends of the plurality of high-strength fixing bolts 401 are sleeved with connecting sleeves 402, and the lower ends of the plurality of connecting sleeves 402 are in close contact with the upper end of the mounting plate 3, the outer ends of the plurality of high-strength fixing bolts 401 are threadedly connected with locking nuts 403, and the locking nuts 403 are in close contact with the connecting sleeves 402.

[0030] During use of this solution, the ladder is placed on the inner wall of the 23-meter inspection hole 7, and the multiple high-strength fixing bolts 401 on the mounting plate 3 are aligned with the preset bolt fixing grooves. Then, the high-strength fixing bolts 401 are driven by tools to be screwed into the bolt fixing grooves for installation and fixation. Then, the connecting sleeve 402 is put on, and the locking nut 403 is tightened and fixed, so that a pair of ladder brackets 1 and the mounting plate 3 are firmly fixed in the 23-meter inspection hole 7.
