[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A furnace maintenance platform with a protective structure includes a platform frame 1. A fixed frame 3 is fixedly connected to the front side of the top of the platform frame 1. Six protective rails 2 and an adjustment mechanism 4 are fixedly connected inside the fixed frame 3. Two limiting mechanisms 5 and an adjustment frame 8 are provided on the front side of the fixed frame 3.

[0029] The adjustment mechanism 4 includes two adjusting columns 401, two threaded sleeves 402, two bushings 403, two fixing rods 404, four connecting rods 405, and a protective plate 406. The surfaces of the adjusting columns 401 and the connecting rods 405 are slidably connected to the interior of the guardrail 2. The interior of the threaded sleeves 402 is rotatably connected to the surface of the adjusting columns 401. The interior of the bushings 403 is rotatably connected to the surface of the threaded sleeves 402. The top of the fixing rods 404 is fixedly connected to the bottom of the bushings 403. The bottom of the fixing rods 404 is fixedly connected to the top of the protective plate 406. The bottom of the protective plate 406 is fixedly connected to the top of the adjustment frame 8.

[0030] In this embodiment: by rotating the threaded sleeve 402 to the surface of the adjusting column 401, the threaded sleeve 402 can easily drive the adjusting column 401 to move and adjust inside the guardrail 2. Under the limitation of the bushing 403, the threaded sleeve 402 can easily drive the fixed rod 404 to move through the bushing 403, and the fixed rod 404 can drive the adjusting frame 8 to move through the protective plate 406. This makes it convenient for the connecting rod 405 to protect the inside of the adjusting frame 8 through the guardrail 2, and makes it convenient for staff to inspect the inside of the large boiler through the adjusting frame 8.

[0031] Specifically, such as Figure 4 As shown, the limiting mechanism 5 includes two rotating plates 501 and four hinges 505 disposed on the front side of the fixed frame 3. The connection between the rotating plates 501 and the hinges 505 is rotatably connected by the hinges 505.

[0032] Specifically, such as Figure 4 As shown, the rotating plate 501 has three mounting slots 502 inside, and two fixing arc sleeves 504 are fixedly connected inside the mounting slots 502.

[0033] Specifically, such as Figure 4 As shown, a limiting sleeve 503 is fixedly connected between the two fixed arc sleeves 504, and the interiors of the three limiting sleeves 503 are in close contact with the surfaces of the adjusting column 401 and the connecting rod 405, respectively.

[0034] In this embodiment: by setting the hinge 505 on the front side of the fixed frame 3, the rotating plate 501 can be easily rotated through the hinge 505, so that the interior of the three limiting sleeves 503 is in close contact with the surface of the adjusting column 401 and the surface of the connecting rod 405 respectively, thereby facilitating the limiting of the adjusting frame 8 and achieving the effect of limiting the adjusting frame 8.

[0035] Specifically, such as Figure 1 As shown, a toolbox 6 is provided at the bottom inside the fixed frame 3, and the two sides of the toolbox 6 are in close contact with one side of each of the two rotating plates 501.

[0036] Specifically, such as Figure 4 , Figure 5 As shown, two limiting blocks 10 are fixedly connected to the bottom of the toolbox 6, and two limiting grooves 9 are opened inside the bottom of the fixing frame 3. The surface of the limiting block 10 is in contact with the inside of the limiting groove 9.

[0037] In this embodiment, by making the two sides of the toolbox 6 in close contact with one side of each of the two rotating plates 501, the toolbox 6 can be conveniently positioned to limit the rotating plates 501, and the surface of the limiting block 10 can be in contact with the inside of the limiting groove 9, thereby facilitating the movement of the toolbox 6 within the limiting groove 9 via the limiting block 10, thus achieving the effect of facilitating the movement of the toolbox 6.

[0038] Specifically, such as Figure 2 As shown, the front side of the fixing frame 3 is provided with two guardrails 11, and the bottom of the guardrails 11 is fixedly connected to the top of the adjusting frame 8.

[0039] Specifically, such as Figure 2 As shown, a protective pad 7 is provided on the top of the adjustment frame 8, and the rear side of the protective pad 7 is fixedly connected to the front side of the protective plate 406.

[0040] In this embodiment: by fixing the bottom of the guardrail 11 to the top of the adjustment frame 8, the guardrail 11 can be used to limit the movement of the staff. The rear side of the protective pad 7 is fixedly connected to the front side of the protective plate 406, so that the protective pad 7 can protect the inside of the adjustment frame 8 through the protective plate 406, thus achieving the effect of protecting the inside of the adjustment frame 8.

[0041] Working principle: The operator is lifted and lowered to a suitable position inside the large boiler via platform frame 1. Then, the threaded sleeve 402 is rotated, causing the adjusting column 401 to move and adjust within the guardrail 2. Limited by the bushing 403, the threaded sleeve 402 moves the fixed rod 404 via the bushing 403. The fixed rod 404 then moves the adjusting frame 8 via the protective plate 406, thus moving the adjusting frame 8 within platform frame 1. This allows the connecting rod 405 to protect the interior of the adjusting frame 8 via the guardrail 2. Then, the rotating plate 501 is rotated, causing the fixed arc sleeve 504 to rotate via the hinge 505 and mounting groove 502. 4. Move the limiting sleeve 503 to the surface of the adjusting column 401 and the connecting rod 405, so that the toolbox 6 moves to the top of the adjusting frame 8 through the limiting block 10 inside the limiting groove 9. Make the two sides of the toolbox 6 make close contact with one side of the two rotating plates 501 respectively, so that the adjusting column 401 and the connecting rod 405 can be limited by the rotating plates 501. This makes it easy to stabilize the adjusting frame 8 and facilitate the workers to inspect the inside of the large boiler through the adjusting frame 8. This solves the problem that most existing maintenance platforms in large boilers can only be used to inspect a certain working area, which is inconvenient. Often, workers need to stick their bodies out to inspect the surrounding area, which is not only inconvenient but also poses certain safety hazards.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
