[0038] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0039] Example 1:

[0040] Referring to Figures 1-7, a maintenance platform for a steel grate in a municipal solid waste incineration power plant includes a support platform 10. Six casters 11 are installed on the lower rear side of the support platform 10. The front end of the support platform 10 is cantilevered. A truss 20 is installed in the middle of the upper side of the front end of the support platform 10. The top front end of the truss 20 extends a certain distance from the support platform 10, forming a trapezoidal structure that is wider at the top and narrower at the bottom. A first pulley block 24 is installed at the front end of the truss 20. A first winch 30 is installed in the middle of the support platform 10. A first wire rope 31 on the first winch 30 is suspended and installed on a basket 40 after passing over the first pulley block 24. In the use state, a counterweight 50 is placed at the rear end of the support platform 10.

[0041] The support platform 10 is used to install the truss 20 and the first winch 30. Casters 11 are installed at the bottom of the support platform 10, allowing it to be easily moved and adjusted as needed. The suspended basket 40 is used for workers to stand on, facilitating their descent to the bottom of the waste pit. During use, a counterweight 50 is placed at the rear of the support platform 10 to balance it and prevent it from tipping over. This structure allows workers to descend to the bottom of the waste pit to inspect and replace the steel grates.

[0042] Furthermore, a support column 16 is welded to the top of the caster 11, and the support column 16 is welded to the bottom of the support platform 10. The support column 16 raises the height of the support platform 10, preventing the threshold at the waste inlet from obstructing the support platform 10.

[0043] In this embodiment, the first winch 30 is a purchased finished product, and the metal frame installed at the bottom of the first winch 30 can be welded to the support platform 10. The casters 11 are swivel casters with brake function. The counterweight 50 can be made of concrete blocks.

[0044] Referring to Figure 1, the truss 20 is a frame made of welded metal profiles. Specifically, the truss 20 includes a top beam 21, longitudinal beams 22 and diagonal beams 23. Multiple longitudinal beams 22 are welded between the top beam 21 and the support platform 10. The longitudinal beams 22 support the top beam 21 at a certain height. The diagonal beams 23 are welded between adjacent longitudinal beams 22 to improve the structural strength of the truss 20.

[0045] The suspended platform 40 can adopt the existing suspended platform structure or the structure shown in Figure 6. In Figure 6, the suspended platform 40 includes a basket body 41, with diagonal rods 42 welded to the four corners of the basket body 41. The tops of the diagonal rods 42 are welded and fixed to the connecting plate 43, and lifting lugs 44 are welded to the connecting plate 43. In use, the first wire rope 31 passes through the lifting lugs 44 and then folds back, and then a wire rope buckle is used to fix the first wire rope 31 to the folded end.

[0046] Example 2:

[0047] Based on Embodiment 1, referring to Figures 1 and 3, a second winch 60 is also installed in the middle of the support platform 10. A first channel 12 is also provided on the support platform 10. A reversing pulley block 13 is installed in the first channel 12. A second wire rope 61 on the second winch 60 passes around the reversing pulley block 13. An auxiliary component 70 is installed at the end of the second wire rope 61. The auxiliary component 70 is used to hook or place the steel grate. A second channel 14 is also provided on the front side of the support platform 10 located in the first channel 12. The second channel 14 is used to pick up and put down the steel grate on the auxiliary component 70.

[0048] The second winch 60 and auxiliary component 70 are installed to lift the replaced steel grate to the unloading hall via the auxiliary component 70, or to lower the new steel grate to the window via the auxiliary component 70. In use, the steel grate is retrieved and placed via the second channel 14.

[0049] In this embodiment, the auxiliary component 70 can be a hook or a box structure as shown in Figure 7.

[0050] Referring to Figure 8, since the garbage bin has a sloping concrete structure on the wall above the window, when the steel grate rubs directly against the sloping surface, firstly, the steel grate may get stuck, and secondly, debris, concrete particles, and dust on the sloping surface may fall off. Therefore, in this embodiment, the auxiliary component 70 is used to place the steel grate.

[0051] Specifically, referring to Figure 7, the auxiliary component 70 includes a box body 71, the upper end of which is provided with a connecting part 72 for connecting with the second steel wire rope 61, and at least four support wheels 73 are installed on one side of the box body 71.

[0052] The connecting part 72 can be an earring welded to the box body 71, or it can be a hole set on the box body 71.

[0053] In use, the steel grate is placed inside the housing 71. Support wheels 73 support the wall, and the steel grate moves on the inclined surface via the support wheels 73. In this embodiment, the support wheels 73 are directional casters, welded to one side of the housing 71.

The first wire rope 31 passes through the third pulley block 26, the second pulley block 25, and the first pulley block 24 in sequence. With the above structure, the first wire rope 31 passes through the top of the truss 20, thus not affecting the loading and unloading of the steel grate on the auxiliary component 70 from the second channel 14.

[0056] Specifically, referring to Figures 1 and 4, the first pulley block 24, the second pulley block 25, and the third pulley block 26 have the same structure. Each of these blocks includes two side plates 241, with a first pulley 243 mounted between them via a first axle 242. The first pulley 243 is fitted onto the first axle 242, or mounted thereon via a bearing. One end of each side plate 241 is fixed to the truss 20, and the other end is welded with a closing plate 245. The first wire rope 31 passes through the first groove 244 on the first pulley 243. The closing plate 245 is provided to prevent the wire rope from slipping off the first pulley 243.

[0057] Referring to Figure 5, the reversing pulley block 13 includes a second wheel axle 131 and a second pulley 133. The second pulley 133 is mounted on the second wheel axle 131 via a bearing 132. Support beams 15 are installed on both sides of the first channel 12 along the width direction of the support platform 10. The top of the two opposing sides of the two support beams 15 are respectively provided with slots 151. The two ends of the second wheel axle 131 are placed in the slots 151 on both sides. A pressure plate 136 is installed on the top of the support beams 15 at the slots 151. The second wire rope 61 passes through the second wheel groove 134 on the second pulley 133.

[0058] The pressure plate 136 can be welded to the support beam 15 or installed on the support beam 15 by screws 137. In Figure 5, the second wheel axle 131 has a flange 135 on one side of the displacement second pulley 133 and a spacer ring on the other side.

[0059] Example 4:

[0060] Based on embodiment 1, 2 or 3, and referring to Figures 1, 2 and 3, the support platform 10 is provided with two “7”-shaped support frames 27 on both sides of the truss 20. One end of the support frame 27 is welded to the support platform 10, and the other end is welded to the top beam 21 of the truss 20 to improve the stability of the truss 20.

[0061] Furthermore, guardrails 80 are welded and installed between two adjacent support frames 27 on each side to improve safety.

[0062] In this embodiment, the guardrail 80 includes a horizontal bar and multiple vertical bars. The horizontal bar is welded between two support frames 27, and the multiple vertical bars are evenly distributed and welded between the horizontal bar and the support platform 10.

[0063] Referring to Figure 3, the front sides of the truss 20 are welded to two support frames 27 located at the front end of the support platform 10 by means of reinforcing rods 28, so as to improve the stability of the truss 20.

[0064] The method of use or principle of this utility model:

[0065] When in use, refer to Figure 8, push the maintenance platform to the garbage inlet and place the counterweight 50.

[0066] Workers enter the suspended platform 40 via the support platform 10, and then lower the workpiece to the maintenance position via the suspended platform below the first winch 30, as shown in Figure 9.

[0067] After the workers on the suspended platform 40 remove a steel grate, they use the second winch 60 to lower the auxiliary component 70 to the corresponding position. The workers on the suspended platform 40 then place the removed steel grate into the auxiliary component 70. After that, the auxiliary component 70 is lifted to the underside of the support platform 10 by the second winch 60, as shown in Figure 7.

[0068] Then, the workers on the support platform 10 retrieve the steel grate from the auxiliary component 70 through the second channel 14, and place the new steel grate into the auxiliary component 70. Afterward, the auxiliary component 70 passes under the second winch 60, as shown in Figure 9. In this way, the workers on the suspended platform 40 can retrieve the new steel grate from the auxiliary component 70 for installation.

[0069] After installing one section, all workers proceed to the unloading hall. At this point, the brakes on caster 11 are released, the support platform 10 is pushed to one side, and the brakes are locked. Workers then use the support platform 10 to enter the suspended platform 40 to install the next steel grate.
