Description

Technical Field

[0001] The utility model relates to the technical field of incinerator maintenance, in particular to a novel support structure for a maintenance platform that can be quickly installed. Background Art

[0002] The inside of a waste incinerator contains flue gas with corrosive gases, and the flue gas temperature is high before entering the superheater, causing high-temperature corrosion to the superheater tubes. Secondly, flue gas ash scale, etc. will also adhere to the inner side of the furnace, affecting the heat exchange efficiency. Therefore, the maintenance of this area is particularly important.

[0003] In the prior art, there are many types of maintenance structures for the furnace of a waste incinerator. One common method is to lower the maintenance platform from the furnace top to the furnace interior by a lifting rope. The staff is located on the maintenance platform, and the maintenance platform moves from top to bottom, and the staff maintains the inner wall of the furnace from high to low. However, this lifting rope-suspended maintenance platform may shake with the operation of the staff, easily threatening the safety of the staff and posing a large safety hazard.

[0004] In addition, another common maintenance structure is divided into two parts: a maintenance platform and a support structure. The maintenance platform is for the staff and maintenance equipment to carry out activities and operations, and the support structure is used to support the maintenance platform. The support structure is generally built with several steel pipes, steel plates and other materials, similar to a scaffolding structure. When performing maintenance, the staff needs to transport these materials into the furnace interior and use connecting components such as bolts and buckles to connect and fix these steel pipe materials. For places with a relatively high position in the furnace, it needs to be built step by step from low to high. This method of gradually building from the ground to the required height not only reduces the maintenance efficiency of the furnace, prolongs the shutdown time of the incinerator, but also increases the labor intensity and operation difficulty.

[0005] Therefore, it is necessary to design a novel support structure for a maintenance platform that can be quickly installed to solve the above problems. Summary of the Utility Model

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments

[0039] Refer to Figures 1 - 5 , a novel maintenance platform support structure that can be quickly installed, including several groups of support components arranged on the boiler steel frame. The support components are arranged at equal intervals, so that the support force of the device on the maintenance platform can be evenly distributed, ensuring the stability of the device's support for the maintenance platform. The support components include:

[0040] The connecting steel frame 1 fixedly connected to the side wall of the boiler steel frame. The connecting steel frame 1 is installed on the boiler steel frame by welding or bolt fixation. A fastening frame 13 is fixedly connected to the side wall of the connecting steel frame 1. The end of the fastening frame 13 away from the connecting steel frame 1 is fixed to the top of the fixed support steel 4. A triangular structure is formed among the fastening frame 13, the fixed support steel 4 and the connecting steel frame 1, improving the load-bearing capacity of the device

[0041] The fixed support steel 4 is fixed to the bottom end of the connecting steel frame 1

[0042] The sliding support steel 3 for supporting the maintenance platform is arranged below the fixed support steel 4, and the sliding support steel 3 is parallel to the fixed support steel 4

[0043] The sliding member is arranged between the sliding support steel section 3 and the fixed support steel section 4, and the sliding support steel section 3 is slidably connected to the fixed support steel section 4 through the sliding member. The sliding member includes: a first pulley group 5, the bottom of the first pulley group 5 is fixedly connected to a position on the top of the sliding support steel section 3 away from the sealing door 2; the longitudinal section of the fixed support steel section 4 is of an I-shaped structure, and the bottoms of the pulleys on the first pulley group 5 are in contact with the inner bottom surface of the fixed support steel section 4; a second pulley group 6, the top of the second pulley group 6 is fixed to the bottom of the fixed support steel section 4, and the second pulley group 6 is located on the side of the fixed support steel section 4 close to the sealing door 2. The longitudinal section of the sliding support steel section 3 is of an I-shaped structure, and the tops of the pulleys on the second pulley group 6 are in contact with the inner top surface of the sliding support steel section 3. The first pulley group 5 and the second pulley group 6 are respectively fixed to the sliding support steel section 3 and the fixed support steel section 4 by welding to ensure the stability of the overall structure of the device. Specifically, the structure of the pulley group consists of a U-shaped mounting frame and two rows of pulleys rotatably connected to the inner side of the mounting frame. The pulleys can reduce the friction between the sliding support steel section 3 and the fixed support steel section 4, facilitating the staff to move the sliding support steel section 3;

[0044] The sealing door 2 is arranged on the boiler water-cooled wall. The sealing door 2 corresponds to the sliding support steel section 3. Specifically, a through hole for the sliding support steel section 3 to pass through is arranged on the boiler water-cooled wall, and the sealing door 2 is arranged in the through hole. The door panel of the sealing door 2 is made of carbon steel or alloy steel, and the door frame of the sealing door 2 is provided with a sealing material. The sealing material is made of silicone rubber, fluororubber, etc. to ensure the sealing performance of the device;

[0045] The arch wall 7 is arranged inside the boiler water-cooled wall. The sealing door 2, the sliding support steel section 3 and the arch wall 7 are on the same horizontal line. The arch wall 7 adopts a water-cooled membrane wall structure to ensure the heat exchange area of the boiler and improve the heat exchange rate. Moreover, the top of the arch wall 7 is inclined, and the top of the arch wall 7 inclines downward towards the inside of the furnace. This can reduce the accumulation of ash scale. A rubber sleeve 14 is sleeved on one end of the sliding support steel section 3 close to the sealing door 2. The rubber sleeve 14 enables a soft contact to be formed between the sliding support steel section 3 and the arch wall 7, improving the stability of the device construction.

[0046] The fixed support steel section 4 is provided with fixing members for fixing the sliding support steel section 3. The fixing members include a first limiting plate 8, a second limiting plate 10, a fixing plate 9, two rows of jacks 11 and three groups of safety pins 12. The first limiting plate 8 is located on the side wall of the fixed support steel section 4 away from the sealing door 2, and the first limiting plate 8 plays a role in restricting the reset of the sliding support steel section 3. The second limiting plate 10 is installed on the side wall of the fixed support steel section 4 close to the sealing door 2. The second limiting plate 10 and the first limiting plate 8 can prevent the sliding support steel section 3 from falling off and separating from the fixed support steel section 4. The fixing plate 9 is arranged on the side wall of the fixed support steel section 4 and is located between the first limiting plate 8 and the second limiting plate 10. The cross-sections of the fixing plate 9, the first limiting plate 8 and the second limiting plate 10 are all in an L-shaped structure. When the fixing plate 9 cooperates with the first limiting plate 8, it can fix the pulley set 5 after reset. At this time, the fixing plate 9 and the first limiting plate 8 are symmetrical. When the sliding support steel section 3 moves into the furnace, when the fixing plate 9 cooperates with the second limiting plate 10, it can fix the pulley set 5 and the sliding support steel section 3. At this time, the fixing plate 9 and the second limiting plate 10 are symmetrical. The jacks 11 are opened on the side wall of the fixed support steel section 4. The jacks 11 are divided into two rows and several columns. The jacks 11 in all columns are arranged at equal intervals, and the distance between adjacent two columns of jacks 11 is adapted to the width of the pulley set 5. This enables the position of the second limiting plate 10 to be adjusted, and further enables the distance that the sliding support steel section 3 enters the furnace to be adjusted, so that the device can be applicable to furnaces of different sizes. The three groups of safety pins 12 are respectively fixedly connected to the side walls of the first limiting plate 8, the second limiting plate 10 and the fixing plate 9. The safety pins 12 are adapted to the size of the jacks 11. The number of pins in each group of safety pins 12 is two and can cooperate with the corresponding columns of jacks 11. The safety pins 12 can prevent the fixing plate 9, the first limiting plate 8 and the second limiting plate 10 from falling off. By setting the fixing members, the staff can quickly assemble the platform support, improving the maintenance efficiency. And compared with the electric drive and fixation of the sliding support steel section 3, this design can avoid the instability when there is a lack of energy such as electric energy, enabling the device to be applicable to different application scenarios, and at the same time reducing the maintenance cost of the support structure.

[0047] The specific working principle of the present utility model is as follows:

[0048] When maintenance is required, the sealing door 2 is opened, and the staff pushes the sliding support steel section 3. The sliding support steel section 3 drives the pulley set 5 to move together. The pulleys on the pulley set 5 and the pulley set 6 rotate, so that the sliding support steel section 3 can easily pass through the sealing door 2 and enter the inside of the incinerator, and finally form a lap joint with the arch wall 7. Since multiple groups of such support structures are provided on the incinerator, multiple sliding support steel sections 3 pass through the furnace and contact the arch wall 7, so that stable support can be provided for the maintenance platform. Among them, the rubber sleeve 14 on the end of the sliding support steel section 3 in contact with the arch wall 7 can improve the stability of the overall structure and reduce the shaking of the maintenance platform;

[0049] When the sliding support steel section 3 moves to the extreme position, one side of the first pulley block 5 abuts against the side wall of the second limiting plate 10. Subsequently, the safety pin 12 on the fixing plate 9 is inserted into the jack 11 located on the other side of the first pulley block 5. In this way, the fixing plate 9 and the second limiting plate 10 can fix both sides of the first pulley block 5, thereby realizing the fixation of the sliding support steel section 3. The method of fixing with the safety pin 12 can improve the stability of the fixation of the sliding support steel section 3, and further ensure that the entire support structure plays a stable supporting role for the maintenance platform. On the contrary, when the maintenance is completed, the fixing plate 9 is removed and the sliding support steel section 3 is reset, so that the side of the first pulley block 5 far from the sealing door 2 contacts the first limiting plate 8. Subsequently, the fixing plate 9 is installed so that the fixing plate 9 and the first limiting plate 8 respectively contact the first pulley block 5 to realize the fixation of the sliding support steel section 3. Through the above design, the staff can effectively and quickly build a strong and stable platform support, thus quickly building a maintenance platform. This reduces potential safety hazards, shortens the cycle of maintaining and repairing equipment, ensures the stable operation duration of the waste incinerator, reduces the maintenance cost, and at the same time reduces the labor intensity and operation difficulty;

[0050] Furthermore, the second limiting plate 10 is fixed on the fixed support steel section 4 by the safety pin 12. When the device is installed on incinerators of different sizes, the moving distance of the sliding support steel section 3 towards the arch wall 7 will change. At this time, the position of the second limiting plate 10 on the fixed support steel section 4 can be adjusted to change the moving range of the sliding support steel section 3, so that the device can be applicable to incinerators of different sizes, improving the practicability and flexibility of the device.

[0051] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
