Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application.

[0029] Please refer to Figures 1-8 , the present application provides a high tower maintenance platform, including a frame column 1.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 andFigure 8 At the bottom end of the frame column 1, a lifting member 5 is installed. At the bottom end of the frame column 1, 12 first support beams 4 arranged in a circular array are also hinged. Specifically, the first support beams 4 are composed of square tubes made of Q235D material with a size of 80*40 and a thickness of 5 mm. The linear distance between the ends of each first support beam 4 is 2200 mm. The first steel wire rope 7 is divided into 12 equal parts with a length of 26.5 m of M4 steel wire and is fixed at the end of the first support beam 4 to serve as the 12-equal-part positioning of the circumferential angle during unfolding, ensuring that after unfolding, the included angle between adjacent two umbrella ribs is 30 degrees, and the equal division length is 4200 mm. The lifting end of the lifting member 5 is connected to a support member 2. On the outer side of the support member 2, 12 second support beams 3 arranged in a circular array are hinged. The other end of each second support beam 3 is respectively hinged to each first support beam 4. The lifting member 5 drives each first support beam 4 and each second support beam 3 to open and contract. Inside the end of each first support beam 4, an electric push rod 8 is installed. Specifically, the telescopic head of the electric push rod 8 is flush with the end of the first support beam 4, and the elongation distance is 500 mm, and the thrust is 700 N. Among them, the top end of the frame column 1 is connected to the hydraulic coke-drilling rod. When it is necessary to repair and inspect the inside of the coke drum, the entire device is moved to the inside of the coke drum, and then the lifting member 5 is started. The lifting member 5 causes the contracted first support beams 4 and second support beams 3 to unfold into an umbrella shape, and then each electric push rod 8 is started again so that each electric push rod 8 abuts tightly against the inner wall of the coke drum respectively. Through the setting of the lifting member 5, each first support beam 4 and second support beam 3 can be unfolded to form an umbrella shape, thereby saving a large amount of work of building a scaffold inside the coke drum. With the aid of the lifting system of the hydraulic coke-drilling rod, it is realized that the operating personnel can lift as needed on this platform inside the coke drum and accurately reach the position where work needs to be done for operation. By installing the electric push rod 8 inside each first support beam 4, each first support beam 4 can abut tightly against the inner wall of the coke drum, improving the stability of the entire maintenance platform and ensuring that the operating personnel can move and operate stably on the platform.

[0031] In this embodiment, the lifting member 5 includes a driving motor 51. The driving motor 51 is installed inside the bottom end of the frame column 1. The output end of the driving motor 51 is installed with a long screw rod 52. The other end of the long screw rod 52 is rotatably connected to the support member 2. A threaded sleeve 53 is arranged at the output end of the driving motor 51. The long screw rod 52 is screwed with the threaded sleeve 53. The driving motor 51 drives the threaded sleeve 53 to rotate. Among them, when the driving motor 51 is started, the threaded sleeve 53 rotates, and then the long screw rod 52 moves up and down, thereby driving the 12 second support beams 3 to move, realizing the folding or unfolding of the 12 second support beams 3 and the 12 first support beams 4. And after unfolding, through the force on the first support plate 21 at the top of the long screw rod 52, the bottom support disk is fixed, and in cooperation with the 12 second support beams 3, it plays a supporting role for the middle section of the 12 first support beams 4, improving the load-bearing capacity and stability of the platform.

[0032] When specifically setting, a first steel wire rope 7 is commonly arranged at the end of each first support beam 4. A second steel wire rope 6 is arranged at the end of each first support beam 4. Specifically, the second steel wire rope 6 is an M10 steel wire rope. At a height of three meters on the other end frame column 1, corresponding to the angle, both ends of the two second steel wire ropes 6 are reliably fixed. The other end of each second steel wire rope 6 is respectively connected to the outside of the frame column 1. Among them, through the setting of the first steel wire rope 7 and the second steel wire rope 6, as the load-bearing traction rope of the platform, it ensures the stability of the load.

[0033] The support member 2 includes a first support plate 21 and a second support plate 23. Connecting rods 22 are arranged in a circular array between the first support plate 21 and the second support plate 23. One end of the long screw rod 52 movably passes through the first support plate 21 and is rotatably connected to the second support plate 23.

[0034] In a specific implementation scheme, first mounting seats 211 are arranged in a circular array on the outside of the first support plate 21. Each second support beam 3 is respectively hinged to the first mounting seats 211. Among them, a first shear pin is commonly arranged on the first mounting seats 211 and the second support beam 3.

[0035] In a specific implementation scheme, a second mounting seat 31 is installed at the bottom end of each second support beam 3. Each second mounting seat 31 is respectively hinged to each first support beam 4. Among them, a second shear pin is commonly arranged on the second mounting seat 31 and the first support beam 4.

[0036] In a specific implementation scheme, the frame column 1 includes a top plate 11, six columns 12, and a mounting plate 13. Specifically, the top plate 11 is connected to the hydraulic descaling drill pipe. The six columns 12 are composed of six square pipes of Q235D material with a size of 80*40 and a thickness of 5 mm. The mounting plate 13 is an annular steel plate of Q235B material. Both ends of the six columns 12 are respectively fixedly connected to the top plate 11 and the mounting plate 13. Twelve first support beams 4 are respectively hinged to the mounting plate 13.

[0037] In a specific implementation scheme, twelve third mounting seats 131 are arranged in a circular array at the bottom end of the mounting plate 13. Each first support beam 4 is respectively hinged to each third mounting seat 131. Among them, a third shear pin is commonly arranged on the third mounting seat 131 and the first support beam 4. The third shear pin is M16.

[0038] The working principle of this high tower maintenance platform:

[0039] The top end of the frame column 1 is connected to the hydraulic coke cutting drill pipe. When it is necessary to perform maintenance and inspection inside the coke drum, the entire device is moved inside the coke drum, and then the lifting member 5 is started. The lifting member 5 causes the retracted first support beam 4 and the second support beam 3 to expand to form an umbrella shape. Then, each electric push rod 8 is started again so that each electric push rod 8 abuts against the inner wall of the coke drum respectively. Through the setting of the lifting member 5, each first support beam 4 and the second support beam 3 can be expanded to form an umbrella shape, thus saving a large amount of work of building a scaffolding inside the coke drum. With the aid of the lifting system of the hydraulic coke cutting drill pipe, it is realized that the operating personnel can lift as required on this platform inside the coke drum and accurately reach the position where work needs to be done for operation. By installing the electric push rod 8 inside each first support beam 4, each first support beam 4 can abut against the inner wall of the coke drum, improving the stability of the entire maintenance platform and ensuring the smooth movement and operation of the operating personnel on the platform.

[0040] It should be noted that the specific model specifications of the drive motor 51 and the electric push rod 8 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0041] The power supply and its principle of the drive motor 51 and the electric push rod 8 are clear to those skilled in the art and will not be elaborated here.
