[0026] It should be noted that, in this embodiment, by assembling the platform structure 2, the hook is fixed on the inner side of the top of the lifting ring 3, so that the supporting frame 23 is pulled up by the hook, and the top of the supporting frame 23 is connected to the beam plate 22 through the main beam 25, providing support for the beam plate 22.

[0027] The supporting legs 28 are rotatably connected to both sides of the outer wall of the supporting base frame 23, and a bottom connecting block 243 is installed with a bottom connecting block 243 on the left side of the top of the supporting leg 28. The inner side of the bottom connecting block 243 is rotatably connected to a telescopic rod 241, and a return spring 242 is sleeved on the outer wall of the telescopic rod 241. One end of the top of the telescopic rod 241 is rotatably connected to a top connecting block 24, and the top of the top connecting block 24 is bolted to the outer wall of the bottom of the construction platform 21. A rotating groove 281 is provided on the outer wall of one end of the supporting leg 28, and a roller 282 is rotatably connected to the inner side of the rotating groove 281.

[0028] It should be noted that, in the present embodiment, when the lifting ring 3 is pulled, the supporting frame 23 is driven to rise through the lifting ring 3. When the supporting frame 23 rises, the roller 282 on the inner side of the rotating groove 281 slides with the outer wall of the elevator shaft wall 11, and then the supporting frame 23 is driven to rise through the lifting ring 3. At the same time, one end of the supporting foot 28 moves to the inner side of the plastic cleaning sleeve 4 on the inner side of the supporting groove 12, and the top connecting block 24 and the bottom connecting block 243 are pushed by the reset spring 242 on the outer wall of the telescopic rod 241, so that the supporting foot 28 is reset. When the control lifting ring 3 is slightly lowered, the supporting foot 28 is limited by the blocking plate 27, so that the bottom of one end of the supporting foot 28 is located on the inner side of the plastic cleaning sleeve 4, so that the supporting foot 28 becomes a supporting point.

[0029] The outer wall bolts on the inner side of the top of the supporting base frame 23 are installed with a blocking plate 27, the outer wall of one side of the main beam 25 and one side of the blocking plate 27 are installed with a mounting plate 26, the top of the mounting plate 26 is bolted with a limiting block 261, the inner side of the limiting block 261 is slidably connected to the limiting side plate 263, a pushing column 262 is welded to the outer wall of one side of the limiting side plate 263, the inner side of the top of the pushing column 262 is threadedly connected to a threaded rod 264, the top of the outside of the threaded rod 264 is fixedly sleeved with a limiting ring 265, and one end of the top of the pushing column 262 is welded with a rotating handle 266.

[0030] It should be noted that, in the present embodiment, the support foot 28 is limited by the blocking plate 27, so that when the support foot 28 is located on the inner side of the plastic outer frame 41, the support foot 28 is limited, so that the bottom of the blocking plate 27 is used to limit the top, so that when the support foot 28 rotates, it is limited, so that the support foot 28 can play a supporting role, and when the rotating handle 266 is rotated, the threaded rod 264 is driven to rotate by the bottom of the rotating handle 266, so that the outer wall of the threaded rod 264 and the inner side of the top of the pushing column 262 are threadedly rotated, and at the same time, the limiting side plates 263 on the outer walls of both sides of the pushing column 262 are located on the inner side of the limiting block 261 to be limited, so that it slides, and one end of the bottom of the pushing column 262 pushes the support foot 28, so that it maintains the rotation angle of the support foot 28, so that it is convenient to descend.

[0031] The outer walls on both sides of the support groove 12 are provided with a No. 1 card slot 121, and the plastic cleaning sleeve 4 includes a plastic outer frame 41, and the outer walls on both sides of the plastic outer frame 41 are fixedly connected with plastic side panels 42, and the outer wall of one side of the plastic side panel 42 is bolted with a positioning block 43, and the outer wall of the positioning block 43 is clamped with the inner side of the No. 1 card slot 121, and the outer wall of the plastic side panel 42 is provided with a telescopic groove 421, and the outer wall of one side of the inner side of the telescopic groove 421 is rotatably connected with a rotating rod 422, and the outer wall of the rotating rod 422 is bolted with a handle 423, and the upper and lower sides of one end of the handle 423 are bolted with a rubber block 425, and the outer walls on the upper and lower sides of the telescopic groove 421 and the surfaces located on the upper and lower sides of the rubber block 425 are provided with a No. 2 card slot 424.

[0032] It should be noted that, in the present embodiment, a support groove 12 is reserved during casting of the elevator shaft wall 11, and then the plastic cleaning sleeve 4 is inserted into the inner side of the support groove 12. Thus, in order to prevent debris and other debris from entering the interior during installation of the elevator, so that the supporting foot 28 cannot enter the inner side, the handle 423 is pulled to separate the outer wall rubber blocks 425 at both ends of the handle 423 from the inner side of the No. 2 slot 424. When pulling the rubber block 425, the rubber blocks 425 on both sides are pulled in two opposite directions to drive the plastic side panels 42 on both sides of the plastic outer frame 41 to move closer to each other, so that the positioning block 43 is separated from the inner side of the No. 1 slot 121, and the plastic outer frame 41 is pulled out of the inner side of the support groove 12, and the debris and other debris inside the support groove 12 are taken out for cleaning, and then the plastic outer frame 41 is pressed back, and the handle 423 is also pressed back at the same time.

[0033] According to the above embodiments, a granular monoammonium phosphate preparation device and a preparation process thereof are also provided, comprising the following steps: Step 1: Cleaning and assembling the support groove. Before construction, clean the support groove by pulling the plastic cleaning sleeve 4 out of the inner side of the support groove 12, thereby taking out the gravel inside the support groove 12; Step 2: Assemble the platform structure and the lifting ring, by installing the platform structure 2 and the lifting ring 3 together with bolts, and then assemble the inner side of the top of the lifting ring 3 on the upper surface of the platform structure 2 with a hook, and then pull it up; Step 3: Control the rotation of the support leg. When the platform structure 2 is pulled upward, the roller 282 on the inner side of one end of the support leg 28 is squeezed by the outer wall of the elevator shaft wall 11, so that one end of the support leg 28 rotates on the inner side of the support frame 23. The column 262 can be pushed downward by rotating the handle 266 to control the rotation angle of the support leg 28. Step 4: Support and fixation with support legs. When the support legs 28 are located on the inner side, the blocking plate 27 limits their position so that the platform structure 2 can be supported when it descends.

[0034] The working principle of the present invention is as follows: the hook is fixed to the inner side of the top of the lifting ring 3 after the platform structure 2 is operated, so that the supporting frame 23 is pulled up by the hook, and the top of the supporting frame 23 is connected to the beam plate 22 through the main beam 25, providing support for the beam plate 22. When the lifting ring 3 is pulled, the supporting frame 23 is driven to rise through the lifting ring 3. When the supporting frame 23 rises, the roller 282 inside the rotating groove 281 slides with the outer wall of the elevator shaft wall 11, and then the supporting frame 23 is driven to move upward through the lifting ring 3. At the same time, one end of the supporting foot 28 moves to the inner side of the plastic cleaning sleeve 4 inside the supporting groove 12, and the top connecting block 24 and the bottom connecting block 243 are pushed by the reset spring 242 on the outer wall of the telescopic rod 241, so that the supporting foot 28 is reset, and the control lifting ring 3 is slightly lowered, so that the supporting foot 28 is limited by the blocking plate 27, so that the bottom of one end of the supporting foot 28 is located on the inner side of the plastic cleaning sleeve 4, so that the supporting foot 28 becomes a supporting point. The blocking plate 27 is used to limit the support foot 28, so that when the support foot 28 is located on the inner side of the plastic outer frame 41, the support foot 28 is limited, so that the bottom of the blocking plate 27 is used to limit the top, so that when the support foot 28 rotates, it is limited, so that the support foot 28 can play a supporting role, and when the handle 266 is rotated, the threaded rod 264 is driven to rotate by rotating the bottom of the handle 266, so that the outer wall of the threaded rod 264 and the inner side of the top of the pushing column 262 are threadedly rotated, and at the same time, the limiting side plates 263 on the outer walls of both sides of the pushing column 262 are located on the inner side of the limiting block 261 to be limited, so that it slides, and one end of the bottom of the pushing column 262 pushes the support foot 28, so that it maintains the rotation angle of the support foot 28, so that it is convenient to descend. The support groove 12 is reserved during casting of the elevator shaft wall 11, and then the plastic cleaning sleeve 4 is inserted into the inner side of the support groove 12. Therefore, in order to prevent debris such as gravel from entering the interior during the installation of the elevator during subsequent use, the outer wall rubber blocks 425 at both ends of the handle 423 are separated from the inner side of the No. 2 slot 424 by pulling the handle 423. When pulling the rubber block 425, the rubber blocks 425 on both sides are pulled in two opposite directions to drive the plastic side panels 42 on both sides of the plastic outer frame 41 to move closer to each other, so that the positioning block 43 is separated from the inner side of the No. 1 slot 121, and the plastic outer frame 41 is pulled out of the inner side of the support groove 12, and the debris such as gravel inside the support groove 12 is taken out for cleaning, and then the plastic outer frame 41 is pressed back, and the handle 423 is also pressed back at the same time.
