Description

Technical Field

[0001] This utility model relates to the technical field of thermal power generation, and in particular to a lifting platform for the maintenance of the furnace of a thermal power boiler. Background Technology

[0002] In the maintenance of thermal power boilers, the internal inspection of the furnace is a crucial step, and workers typically need to use a lifting platform to enter the furnace for operations. However, the internal structure of the furnace is complex, and during maintenance, bolts, debris, and other objects may fall from above. These falling objects could not only injure workers on the platform but also damage maintenance tools, posing a significant safety hazard.

[0003] Most existing lifting platforms only have lifting and load-bearing functions, lacking effective protection structures against falling objects. Although some platforms are equipped with simple protective plates, the protection range is fixed and cannot be flexibly adjusted according to actual maintenance needs. Furthermore, they are unable to effectively intercept smaller falling objects, resulting in poor protection. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lifting platform for the maintenance of the furnace of a thermal power boiler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lifting platform for furnace maintenance of a thermal power boiler includes a base plate, a platform on the base plate, sleeves fixedly connected to one end and the other end of the platform, round rods movably passing through both sleeves, bolts threaded through both sleeves, and two bolts respectively contacting corresponding round rods. The two round rods are fixedly connected to the same rod body, and a cloth surface is fixedly connected between the rod body and the platform.

[0007] Preferably, wheels are fixedly connected to all four corners of the base plate, two sliding rods are movably connected through one end and the other end of the base plate, and multiple sliding rods are fixedly connected to corresponding plates respectively. Studs are threaded through one end and the other end of the base plate, and two studs are rotatably connected to corresponding plates respectively. Rubber pads are fixedly connected to both plates.

[0008] Preferably, the base plate is rotatably connected to a second frame, the platform is rotatably connected to a first frame, the first frame and the second frame are rotatably connected, and each of the first frame and the second frame is rotatably connected to a slider at one end. Each of the two sliders is slidably connected to two slide rails, and multiple slide rails are respectively fixedly connected to the top of the base plate and the bottom of the platform. The base plate is fixedly connected to a push rod, and the output end of the push rod is fixedly connected to the slider of the base plate.

[0009] Preferably, the platform is fixedly connected to a guardrail, which is C-shaped when viewed from above.

[0010] Preferably, the fabric surface is made of fiberglass cloth.

[0011] Preferably, both studs are fixedly connected to a handle.

[0012] Preferably, both rubber pads have multiple grooves at their bottom.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using a platform, sleeve, bolts, round rods, and fabric panels, the distance between the rods and the platform is adjusted through a structure where the round rods move within the sleeve. This is combined with the bolts on the sleeve being tightened and fixed to the round rods. When the protection range needs adjustment, the distance between the rods and the platform can be easily changed by sliding the round rods within the sleeve. This allows the fabric panels to unfold to different degrees depending on the distance, enabling flexible adjustment of the protection range according to actual maintenance needs and effectively solving the problem of fixed protection range in existing protective plates. Furthermore, the fabric's good flexibility and containment properties effectively catch and intercept various objects falling from above, including smaller ones, overcoming the shortcomings of traditional protective plates in intercepting small objects and improving the comprehensiveness and reliability of protection. Simultaneously, the bolt fixing method is simple to operate and allows for quick locking of the distance, ensuring the fabric remains stably unfolded during operation, thus compensating for the deficiencies in the falling object protection function of existing lifting platforms.

[0015] 2. Through the cooperation between the base plate, wheels, studs, plate, and rubber pad, the studs drive the plate to make the rubber pad contact the ground, which can effectively limit the movement of the base plate driven by the wheels. The height of the plate can be adjusted with the studs to make the rubber pad fit tightly against the ground, increasing the friction with the ground and stabilizing the movement of the base plate. The rubber pad is soft and will not easily damage the ground when in contact with it. The fixing operation is simple and does not require complicated tools. The base plate can be quickly fixed and loosened, flexibly meeting the needs of use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 A lifting platform for furnace maintenance of a thermal power boiler includes a base plate 1, a platform 2 on the base plate 1, and sleeves 8 fixedly connected to one end and the other end of the platform 2. The sleeves 8 are used to guide the movement of round rods 10. The round rods 10 are movably inserted through both sleeves 8 and can move within the inner wall of the corresponding sleeves 8. Bolts 9 are threaded through both sleeves 8 and contact the corresponding round rods 10 respectively. The friction generated by the contact between the bolts 9 and the round rods 10 can restrict the movement of the round rods 10. The two round rods 10 are fixedly connected to the same rod body 11. A cloth surface 12 is fixedly connected between the rod body 11 and the platform 2. The cloth surface 12 is used to catch objects falling from above. The distance between the rod body 11 and the platform 2 is adjusted by moving the round rods 10 within the sleeves 8 and is fixed with the bolts 9. The sliding rod 10 can change the spacing, allowing the fabric 12 to unfold according to the spacing, flexibly adjusting the protection range and solving the problem of fixed range of existing protective plates; the fabric 12 is flexible and can effectively catch falling objects, including small objects, overcoming the defect of insufficient interception; the bolt fixing operation is simple, ensuring the stability of the fabric 12 and making up for the lack of protection.

[0024] In this embodiment, wheels 18 are fixedly connected to each of the four corners of the base plate 1. The wheels 18 are used for overall movement. Two sliding rods 16 are movably connected through one end and the other end of the base plate 1. The sliding rods 16 can guide the lifting and lowering movement of the plate 14. Multiple sliding rods 16 are fixedly connected to corresponding plates 14. Studs 13 are threaded through one end and the other end of the base plate 1. Two studs 13 are rotatably connected to corresponding plates 14. The rotation of the studs 13 can adjust the lifting and lowering movement of the plate 14. Rubber pads 15 are fixedly connected to both plates 14. The rubber pads 15 are used to contact the ground to limit the movement of the wheels 18 and increase the overall stability when stationary. The base plate 1 is rotatably connected to a second frame 4, and the platform 2 is rotatably connected to a first frame 3. The first frame 3 and the second frame 4 are rotatably connected. The first frame 3 and the second frame 4 are size-matched to form symmetrical support, forming... The cross-support structure has a slider 5 rotatably connected to one end of the first frame 3 and the second frame 4. The two sliders 5 are slidably connected to two slide rails 6. The sliding connection between the sliders 5 and the slide rails 6 is used to ensure the stability of the rotation and movement of the first frame 3 and the second frame 4. Multiple slide rails 6 are fixedly connected to the top of the base plate 1 and the bottom of the platform 2 respectively. The base plate 1 is fixedly connected to a push rod 7, which is a hydraulic cylinder. The output end of the push rod 7 is fixedly connected to the slider 5 of the base plate 1. The platform 2 is fixedly connected to a guardrail 19. The guardrail 19 is C-shaped when viewed from above, so that one can stand on the platform 2 at one end of the guardrail 19. The fabric 12 is made of fiberglass cloth, which has high temperature resistance and tear resistance properties to ensure the durability of the fabric 12. Both studs 13 are fixedly connected to handles 17. Both rubber pads 15 have multiple grooves at the bottom to increase the friction with the ground and drain dust and water from the contact surface.

[0025] The working principle of this embodiment is as follows: In use, the distance between the rod 11 and the platform 2 is first adjusted by sliding the round rod 10 inside the sleeve 8, so that the cloth surface 12 between them unfolds to the required protection range as the distance changes. Then, the bolt 9 on the sleeve 8 is tightened to contact and fix the round rod 10. Subsequently, the handle 17 is turned to drive the stud 13 to move synchronously, which drives the plate 14 to move down so that the rubber pad 15 is in close contact with the ground. The increased friction restricts the wheel 18 to drive the base plate 1 to move, thus completing the fixation. If adjustment is needed, the operation is reversed to loosen the fixation, which can flexibly adapt to different working conditions. After fixation, the push rod 7 is connected to the external control device. The push rod 7 can drive the corresponding slider 5 to move towards one end of the cloth surface 12. In this way, the first frame 3 and the second frame 4 rotate to adjust the platform 2 upward and form an X-shaped support, so that the furnace of the thermal power boiler can be inspected at different heights.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
