[0020] Example 1 See also Figure 1 The installation and connection method of each component is as follows: first, when installing the eaves template at the bottom of the slope roof, reserve an extra width of 100mm, install a circle of annular slide rails 25 on the reserved eaves template, use screws to fix the annular slide rails 25 on the eaves template, use screws to fix the slider to the lower part of the door bracket 23, install the slider on the annular slide rails 25, and then complete the installation of the door bracket 23. Then, after the installation of the central pre-processing parts of the silo roof at the grain inlet is completed, refer to Figures 2 to 3, install the central axis 1 on the central embedded part of the silo roof at the grain inlet. Above the central axis 1 is a hollow cover plate 4 with a slot, and below is a square shaft body 3. Three upper, middle and lower bearings 2 are arranged in the shaft body 3. The central axis 1 arranged in the bearing 2 is 3 meters long. Use a set of tension bolts 6 and a downward pressure beam 5 to tie the central axis 1 to the silo roof support frame rod system 9 to achieve the purpose of vertically fixing the central axis 1. Install a symmetrical set of top supports 7 between the shaft body 3 and the central embedded part of the silo roof at the grain inlet to achieve the purpose of horizontally fixing the central axis 1. Then install the crossbar bracket 24 on the top of the central axis 1 with bolts. There are two slots on the short crossbar of the crossbar bracket 24 (not shown in the figure). Then use two large diagonal bars 12 to connect the short crossbar of the crossbar bracket 24 and the gate bracket 23 and fix them with bolts. See. Figure 4 , adjust the height of the door bracket 23 so that the angle between the large oblique rod 12 and the horizontal plane is consistent with the angle between the conical slope roof of the warehouse and the horizontal plane. In one or more embodiments, the large oblique rod 12 is composed of a small shell beam and has a certain pressure bearing capacity. Then, bolts are used to install and fix the rack 10 on the top surface of the large oblique rod 12, and a mobile bracket is set on the two large oblique rods 12. The pillars at the four corners of the mobile bracket are four extendable oil cylinders. The connection method between the oil cylinder and the large oblique rod 12 is: a horizontal pipe is welded on the outer wall of the oil cylinder, and the horizontal pipe can be hung on the large oblique rod 12. The part where the horizontal pipe contacts the large oblique rod 12 is bolted with a first gear 15 with a motor. The first gear 15 with a motor is meshed with the rack 10 on the large oblique rod 12, and can drive the mobile bracket and the equipment on the mobile bracket to move up and down along the large oblique rod 12.

[0021] Example 2 Embodiment 2 is substantially the same as Embodiment 1, except that: The ends of the four oil cylinder telescopic rods 13 are connected to the four corners of a square base 17 by bolts. In one or more embodiments, the square base 17 is composed of two longitudinal rods between the ends of the four oil cylinder telescopic rods 13, two cross rods connecting the two longitudinal rods, and two vibrating rod guide rods 18. Three sets of parallel pulleys with motors are installed on the square base 17 by bolts, and scrapers 11 are evenly arranged on the pulleys. In one or more embodiments, the scrapers 11 are made of rubber. Two rows of small-diameter vibrating rods 19 are arranged in the middle of the three sets of pulleys, and each vibrating rod 19 is connected by a vibrating rod connecting bracket 20. The four-corner sleeves 22 of the vibrating rod connecting bracket 20 are on the toothed support rods 16 at the four corners of the square base 17. The four corners of the vibrating rod connecting bracket 20 are installed with second gears 22 with motors, and the lifting of the vibrating rod 19 can be controlled by the motor.

[0022] Example 3 See also Figure 5The vibrating construction method for pouring concrete on the roof of a shallow round silo of the present invention, that is, the pouring, vibrating and finishing process of the silo roof slope roof, comprises the following steps: S1. After the equipment is installed, one end of the large oblique rod 12 is connected to the crossbar bracket 24 at the top of the central axis, and the other end is connected to the door bracket 23 on the annular slide rail 25. The door bracket 23 slides on the annular slide rail 25, driving the large oblique rod 12 to make a circular motion around the central axis 1.

[0023] S2. When pouring the silo roof slope concrete, pour from the outer circle of the silo roof to the inner circle of the silo roof around the center of the silo roof. After the concrete comes out of the pump pipe, it accumulates on the silo roof formwork 27. Adjust the position of the large diagonal rod and 12 mobile brackets so that the equipment on the mobile bracket is located directly above the accumulated concrete.

[0024] S3, see Figure 6 , adjust the length of the cylinder telescopic rod 13 so that the end of the scraper 11 on the pulley is located at the designed surface 26 of the silo roof concrete, then start the vibrating rod 19 and adjust the height of the vibrating rod 19 so that it is inserted into the concrete, and the accumulated concrete begins to collapse and slide after being vibrated.

[0025] S4, the scraper 11 on the pulley scrapes the sliding concrete to the top of the slope, completing the concrete vibrating and finishing of the slope surface.

[0026] S5. See Figure 7 When the equipment on the large diagonal rod 12 needs to adjust its position according to the on-site pouring conditions, the gear 22 with the second motor is controlled to lift the vibrating rod 19, and the large diagonal rod 12 is pushed to rotate around the central axis 1 to change the horizontal position of the vibrating and leveling equipment. The gear 15 with the first motor is controlled to drive the equipment to slide up and down on the large diagonal rod 12 to complete the longitudinal movement of the vibrating and leveling equipment.

[0027] S6. See Figure 8 When encountering obstacles, the oil cylinder can be retracted to lift the square base 17 and the equipment on it to bypass the obstacles. The equipment on the large inclined rod 12 can make circular motion around the central axis 1 and can also slide up and down on the large inclined rod 12 to cover the entire silo roof casting surface.
