[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] like Figure 1-3As shown, the steel truss platform for supporting formwork for shallow silo comprises a ring beam frame 1; a diagonal brace frame 11 is installed in the middle of the ring beam frame 1; two groups of connecting rods 12 are fixedly connected to the bottom of the ring beam frame 1; a fixing plate 13 is fixedly connected to the bottom of the connecting rod 12; a first clamping plate 14 is slidably connected to the bottom of the fixing plate 13; a rain cover 15 is fixedly connected to the inner wall of the first clamping plate 14, and the middle part of the rain cover 15 is horn-shaped; a first rotating shaft 16 is rotatably connected to the middle part of the first clamping plate 14; a second clamping plate 17 is fixedly connected to the top of the first rotating shaft 16; when working, the staff needs to connect the ring beam frame 1 and the diagonal brace frame After the ring beam frame 11 is welded together, the ring beam frame 1 and the diagonal support frame 11 are installed on the warehouse foundation, and the warehouse roof and the diagonal support frame 11 are installed together. Two sets of connecting rods 12 are arranged at the bottom of the ring beam frame 1, so that the connecting rods 12 support and fix the fixed plate 13. When the first clamping plate 14 needs to be used, the staff can align the convex position of the top of the first clamping plate 14 with the clamping groove in the middle of the fixed plate 13, and push the first clamping plate 14 upward until the second clamping plate 17 passes over the top of the fixed plate 13. Then the other staff can rotate the first rotating shaft 16 by hand. After the first rotating shaft 16 rotates, the second clamping plate 17 can be driven to move, so that the second clamping plate 17 and the first clamping plate 14 protrusions will gradually present a horizontal misalignment state. At this time, the fixing plate 13 can be loosened, so that after the fixing plate 13 loses its supporting force, the middle part of the second clamping plate 17 is deeply in contact with the top of the fixing plate 13 with the downward gravity, and the rain cover 15 is fixed. When it rains or impurities fall from the outside, they will first contact the trumpet-shaped rain cover 15, and then be discharged to the outside through the pipe at the end. When it is necessary to disassemble and load goods from the middle of the ring beam frame 1 , rotate the two sets of first rotating shafts 16 again, and make the second clamping plate 17 overlap with the protruding block of the first clamping plate 14. This step cooperates with the rain shield 15 to reduce the problem that when the ring beam frame 1 is working in the rainy season, rainwater from the outside directly enters the warehouse through the ring beam frame 1, and it is difficult for the staff to block the top of the ring beam frame 1 in the first time, causing damage to the materials. The overall removal of the rain shield 15 can improve its flexibility in use and reduce the problem of certain troubles caused by the rain shield 15 blocking when loading and unloading materials from the middle of the ring beam frame 1.

[0026] like Figure 2 and 4As shown, the inner wall of the rain cover 15 is fixedly connected with a bracket 2; the middle part of the bracket 2 is rotatably connected with a second shaft 21; the middle part of the second shaft 21 is fixedly connected with a rotating fan 22; the middle part of the second shaft 21 is fixedly connected with a plurality of telescopic rods 23; the end of the telescopic rod 23 is fixedly connected with an impact ball 24, and the impact ball 24 is arranged in contact with the inner wall of the rain cover 15; when working, by arranging a rotatable second shaft 21 inside the rain cover 15, when external rain falls or a large wind force enters the inside of the ring beam frame 1, its power source will directly contact the middle part of the rotating fan 22, and at the same time, the rotating fan 22 will rotate as a whole, and the plurality of telescopic rods 23 will The impact ball 24 is rotated synchronously so that it contacts the inner wall of the rain shield 15, and squeezes the middle part of the telescopic rod 23 to retract during the contact process. Then, the impact ball 24 can be reset after passing the middle part of the rain shield 15, and this process is repeated. This step, in conjunction with the rotatable impact ball 24, can improve the cleanliness of the inner wall of the rain shield 15, reduce the problem of certain corrosion caused by more raindrops or impurities adhering to the inside of the rain shield 15, and at the same time improve the smoothness of the inside of the rain shield 15, reduce the stability of the subsequent liquid when sliding inside the rain shield 15, and the telescopic telescopic rod 23 can reduce the problem of gradual jamming between the impact ball 24 and the inner wall of the rain shield 15.

[0027] like Figure 3 As shown, two groups of reinforcement plates 3 are fixedly connected to the bottom of the fixed plate 13; a first magnetic block 31 is fixedly connected to the middle of the reinforcement plate 3; a second magnetic block 32 is fixedly connected to the middle of the second clamping plate 17, and the second magnetic block 32 and the first magnetic block 31 are repelling each other; during operation, by arranging the second magnetic block 32 in the middle of the second clamping plate 17, when the first clamping plate 14 is installed, and the second clamping plate 17 moves upward and passes over the top of the fixed plate 13, the second magnetic block 32 will gradually approach the position of the first magnetic block 31 and generate a reactionary repulsive force, and push the second clamping plate 17 to rotate and be placed horizontally on the top of the fixed plate 13. This step, combined with the second magnetic block 32 with a repulsive setting, can reduce the problem that the staff needs to support the middle of the rain cover 15 with one hand and rotate the bottom of the first rotating shaft 16 in sequence with the other hand during the installation of the first clamping plate 14, thereby improving the speed of the staff in installing the first clamping plate 14 and the rain cover 15.

[0028] like Figure 2 and 4As shown, the inner wall of the rain shield 15 is provided with a support rod 4; a guide plate 41 is fixedly connected to the end of the support rod 4, and the inner wall of the guide plate 41 is horn-shaped; the guide plate 41 is located at the top of the rotary fan 22; when working, by arranging the support rod 4 on the inner wall of the rain shield 15, when the external rain or wind passes through the middle part of the ring beam frame 1, part of the wind or rain will contact the guide plate 41 first, and then be concentrated and contact the middle part of the rotary fan 22. This step is combined with the guide plate 41 to reduce the problem that the external wind or rain is small, making it difficult to drive the rotary fan 22 to rotate, and reduce the problem of the second rotating shaft 21 being stuck in the middle part of the bracket 2. At the same time, it can increase the force of the impact ball 24 hitting the inside of the rain shield 15, thereby improving the cleanliness of the inside of the rain shield 15.

[0029] like Figure 4 As shown, a spring rod 5 is fixedly connected to the inner wall of the rain cover 15; the output end of the spring rod 5 is fixedly connected to the support rod 4; when working, by arranging the spring rod 5 at the end of the support rod 4, when the external wind force pushes the guide plate 41 with a large force, the spring rod 5 will be compressed to retract, and at the same time, it will have elasticity, so that the guide plate 41 will shake. This step cooperates with the spring rod 5 that is arranged to make the guide plate 41 shake, reduce the impurities or water stains attached to the middle thereof to be thrown out, and reduce the need for frequent maintenance of the guide plate 41.

[0030] like Figure 3 As shown, two groups of friction plates 6 are fixedly connected to the top of the fixed plate 13, and the two groups of friction plates 6 are arranged near the second clamping plate 17; when working, by arranging the friction plate 6 on the top of the fixed plate 13, when the second clamping plate 17 is placed horizontally on the top of the fixed plate 13, the bottom of the second clamping plate 17 will be deeply in contact with the friction plate 6. This step cooperates with the friction plate 6 to improve the friction force of the second clamping plate 17 when it is fixed and placed, and reduce the problem of angle deviation or separation of the first clamping plate 14 as a whole due to the shaking of the second clamping plate 17 when working, thereby improving the stability of the rain cover 15 when working.

[0031] like Figure 4 As shown, a gasket 7 is fixedly connected to the middle of the impact ball 24; when working, by arranging the gasket 7 in the middle of the impact ball 24, when the impact ball 24 is close to the inner wall of the rain cover 15, the gasket 7 will directly perform the impact work. This step cooperates with the gasket 7 to reduce the problem of large wear and tear of the impact ball 24 after long-term use, thereby improving the service life of the rain cover 15.

[0032] Working principle: After the ring beam frame 1 and the diagonal support frame 11 are welded together, the ring beam frame 1 and the diagonal support frame 11 are installed on the warehouse foundation, and the warehouse roof and the diagonal support frame 11 are installed together, two sets of connecting rods 12 are arranged at the bottom of the ring beam frame 1, so that the connecting rods 12 support and fix the fixed plate 13. When the first clamping plate 14 needs to be used, the staff can align the raised position on the top of the first clamping plate 14 with the clamping groove in the middle of the fixed plate 13, and push the first clamping plate 14 upward until the second clamping plate 17 passes over the top of the fixed plate 13. Then the other staff can rotate the first rotating shaft 16 by hand, so that the rotation of the first rotating shaft 16 can drive the second clamping plate 17 to move, so that the second clamping plate 17 and the first clamping plate 17 are aligned. The protrusion of one card plate 14 will gradually present a horizontally dislocated state. At this time, the fixing plate 13 can be loosened, so that after the fixing plate 13 loses its supporting force, the middle part of the second card plate 17 is deeply contacted with the top of the fixing plate 13 with the downward gravity, and the rain cover 15 is fixed, so that when it rains outside or impurities fall, they will contact the trumpet-shaped rain cover 15 first, and then be discharged to the outside through the pipe space at the end. When it is necessary to disassemble and load goods from the middle part of the ring beam frame 1, the two sets of first rotating shafts 16 are rotated again, and the second card plate 17 and the protrusion of the first card plate 14 are overlapped. By arranging a rotatable second rotating shaft 21 inside the rain cover 15, when rainwater from the outside falls or a strong wind force enters the inside of the ring beam frame 1, its The power source will directly contact the middle of the rotating fan 22, and at the same time make the rotating fan 22 rotate as a whole, and the multiple sets of telescopic rods 23 will rotate synchronously, so that the impact ball 24 will contact the inner wall of the rain cover 15, and squeeze the middle of the telescopic rod 23 to retract during the contact process, and then the impact ball 24 can be reset after passing the middle of the rain cover 15, and this is repeated. By setting a second magnetic block 32 in the middle of the second card plate 17, when the first card plate 14 is installed, and the second card plate 17 moves upward and passes the top of the fixed plate 13, the second magnetic block 32 will gradually approach the position of the first magnetic block 31 and generate a reaction repulsive force, and push the second card plate 17 to rotate and be placed horizontally on the top of the fixed plate 13, and by setting a second magnetic block 32 on the inner wall of the rain cover 15 There is a support rod 4, so that when external rain or wind passes through the middle of the ring beam frame 1, part of the wind or rain will contact the guide plate 41 first, and then be concentrated and contact the middle of the rotary fan 22. By arranging a spring rod 5 at the end of the support rod 4, when the external wind force pushes the guide plate 41 with a large force, the spring rod 5 will be compressed to retract, and at the same time, it will have elastic force, so that the guide plate 41 will shake. By arranging a friction plate 6 on the top of the fixed plate 13, when the second clamping plate 17 is placed horizontally on the top of the fixed plate 13, the bottom of the second clamping plate 17 will deeply contact with the friction plate 6. By arranging a gasket 7 in the middle of the impact ball 24, when the impact ball 24 is close to the inner wall of the rain cover 15, the gasket 7 will directly impact.
