[0059] Step S205, please refer to Figure 5 , install the platform truss 150 on the threaded sleeve 140 around the first standard section 111 on the silo floor, so that the platform truss 150 is sleeved on the first standard section 111 through the center through hole, and the first standard section 111 is used as the previous standard section 111.

[0060] Step S206, please refer to Figure 6 , hoist and install the rear standard section 111 on the front standard section 111.

[0061] Step S207, please refer to Figure 6, release the connection between the threaded sleeve 140 and the previous standard section 111, keep the motor platform 120 locked with the previous standard section 111, control the synchronous rotation of each spiral motor 130 to drive the threaded sleeve 140 and the platform truss 150 thereon to rotate and rise along the previous standard section 111 on the next standard section 111, and lock the threaded sleeve 140 with the next standard section 111. That is, this step S207 is the platform truss 150 rotating and rising, wherein the dynamic changes of the platform truss 150 rotating and rising are as follows Figure 2 to Figure 1 The changing process is shown.

[0062] Step S208, please refer to Figure 6 , keep the threaded sleeve 140 locked and connected with the next standard section 111, release the connection between the motor platform 120 and the previous standard section 111, control the synchronous rotation of each spiral motor 130 to drive the motor platform 120 to vertically lift along the previous standard section 111 on the next standard section 111, and lock the motor platform 120 with the next standard section 111. That is, step S208 is the rise of the motor platform 120, wherein the rising process of the motor platform 120 is as follows Figures 1 to 2 The changing process is shown.

[0063] Step S209, please refer to Figures 7 and 8 Repeat steps S206 to S208 to alternately raise the platform truss 150 and the motor platform 120 until the platform truss 150 rises to the top of the silo, then fix the platform truss 150 to the silo wall to complete the rotational installation of the construction platform 100 inside the silo.

[0064] The embodiment of the present invention provides a silo internal construction platform 100 and its installation method, wherein the platform truss 150 and the center column 110 are connected by a threaded sleeve 140 and a screw motor 130. During the installation and construction of the silo internal construction platform 100, after the first standard section 111 of the center column 110 is installed on the silo floor, the platform truss 150 can be installed on the first standard section 111 on the silo floor. After the subsequent standard sections 111 are sequentially added to the first standard section 111, the platform truss 150 and the motor platform 120 are alternately raised by the threaded connection structure of each screw motor 130 and the threaded sleeve 140, and the synchronous rotation of each screw motor 130 controls the alternating rise of the platform truss 150 and the motor platform 120 until the platform truss 150 rises to the top of the silo. The platform truss 150 is then fixed to the silo wall, completing the rotational installation of the silo internal construction platform 100, avoiding the safety hazard of the platform truss 150 falling from a height during high-altitude installation.

[0065] In order to realize the rotational installation of the platform truss 150, the installation method of the internal construction platform 100 of the silo provided in an embodiment of the present invention also includes an installation method of the center column 110. A standard section 111 can be installed, and the platform truss 150 and the motor platform 120 can be alternately controlled to be lifted to the installation height of the standard section 111. Figures 5 to 8 This example illustrates an installation method in which one standard section 111 is installed to control the rotation and elevation of the platform truss 150. However, the method for rotating and elevating the platform truss 150 is not limited to the above method. Alternatively, after all standard sections 111 are installed to form a complete center column 110, the platform truss 150 and the motor platform 120 can be alternately controlled to be raised to the top of the center column 110.

[0066] The present invention further provides a method for dismantling the internal construction platform 100 of the silo, wherein the dismantling method is the reverse process of the installation method, comprising:

[0067] Step S210, please refer to Figure 8 , release the connection of the platform truss 150 on the silo wall.

[0068] Step S211, please refer to Figures 8 to 7 , the connection between the motor platform 120 and the standard section 111 at the height where it is located is released, the threaded sleeve 140 is kept connected to the standard section 111 at the height where it is located, the spiral motors 130 are controlled to rotate synchronously to drive the motor platform 120 to descend vertically, and the motor platform 120 after the descending height is locked and connected to the standard section 111 at the height where it is located. Step S211 is the process of controlling the motor platform 120 to descend. The direction of rotation of the spiral motor 130 when driving the motor platform 120 to descend is opposite to the direction of rotation when the motor platform 120 is ascending.

[0069] Step S212, releases the connection between the threaded sleeve 140 and the standard section 111 at its height, keeps the motor platform 120 locked in connection with the standard section 111 at its height, controls the synchronous rotation of each spiral motor 130, drives the threaded sleeve 140 and the platform truss 150 thereon to rotate and descend relative to the standard section 111, and locks the threaded sleeve 140 after descending to the standard section 111 at its height. That is, step S212 is the process of controlling the platform truss 150 to rotate and descend. Wherein, according to the spacing between the threaded sleeve 140 and the motor platform 120, the order of step S212 and step S211 can be interchanged. Wherein, the direction of rotation when the spiral motor 130 drives the platform truss 150 to rotate and descend is opposite to the direction of rotation when the platform truss 150 is driven to rotate and ascend.

[0070] Step S213 , repeating steps S211 to S212 , so that the motor platform 120 and the platform truss 150 are alternately lowered until the motor platform 120 is lowered to the silo floor.

[0071] In step S214 , the platform truss 150 , the threaded sleeve 140 , the screw motor 130 , and the motor platform 120 are removed from the silo floor, completing the rotational removal of the construction platform 100 inside the silo.

[0072] The embodiment of the present invention provides an internal silo construction platform 100 and a dismantling method thereof. The platform truss 150 and the center column 110 are connected by a threaded sleeve 140 and a spiral motor 130. When the internal silo construction platform 100 is dismantled, after the connection of the platform truss 150 to the silo wall is released, the threaded sleeve 140 and the spiral motor 130 are connected by a threaded sleeve 140. Through the synchronous rotation of each spiral motor 130, the motor platform 120 and the platform truss 150 are controlled to alternately descend until the motor platform 120 descends to the silo floor, thereby realizing the dismantling construction of the platform bridge on the silo floor, avoiding the safety hazard of the platform truss 150 falling from a high altitude during the high-altitude dismantling operation.

[0073] The method for dismantling the construction platform 100 inside the silo provided in an embodiment of the present invention also includes a method for dismantling the central column 110. After step S214, the standard sections 111 of the central column 110 can be hoisted and removed from top to bottom. Alternatively, before step S214, after the platform truss 150 is lowered to the height of one standard section 111, the standard sections 111 above it are removed by the lowered platform truss 150 and temporarily placed on the platform truss 150. After the platform truss 150 is lowered to the silo floor, the standard sections 111 temporarily placed on the platform truss 150 are first hoisted to the silo floor before performing the dismantling construction in step S214.

[0074] Please refer to Figure 1 、 Figure 2 and Figure 4In order to achieve the purpose of detachably connecting the motor platform 120 to the center column 110, and to achieve the purpose of detachably connecting the threaded sleeve 140 to the center column 110, the silo internal construction platform 100 provided by the embodiment of the present invention has the motor platform 120 and the threaded sleeve 140 detachably connected to the center column 110 at corresponding heights via respective locking mechanisms 160. The locking mechanism 160 can offset torsional forces and prevent the motor platform 120 or the threaded sleeve 140 from rotating with it. The locking mechanism 160 includes a plurality of grooves 161 arranged around the center column 110, and a locking member 162 that is inserted into or removed from the grooves 161. When the locking member 162 is inserted into the groove 161 at the corresponding position on the center column 110, the locking mechanism 160 connects the motor platform 120 and the threaded sleeve 140 to the center column 110. When the locking member 162 is pulled out of the groove 161 at the corresponding position on the center column 110, the locking mechanism 160 removes the motor platform 120 or the threaded sleeve 140 from the center column 110. The locking member 162 can be a plate along the radial direction of the center column 110, such as a telescopic plate. Of course, the locking mechanism 160 is not limited to the above method, and can also be a locking bolt that is detachably connected between the motor platform 120 and the center column 110. Correspondingly, the center column 110 is provided with a number of threaded holes connected to the locking bolts at equal intervals along its height direction. When the locking bolt is a tie bolt, the threaded hole on the center column 110 can be a through hole. To achieve rapid locking and unlocking, the locking mechanism can also be a latch. Inserting the latch maintains the locked connection, and removing the latch releases the connection. The locking mechanism 160 on the motor platform 120 is preferably located at its lower end to avoid obstruction by the threaded sleeve 140. The locking mechanism 160 on the threaded sleeve 140 can be located at its upper or lower end, or alternatively, on the platform truss 150.

[0075] Please refer to Figures 1 to 2 In order to avoid the threaded sleeve 140 from obstructing the central column 110 during rotation, the embodiment of the present invention provides an internal construction platform 100 for a silo, wherein the standard section 111 is a tubular member having an inner flange. The tubular member may be a round tube. Adjacent standard sections 111 are detachably connected via the flange threads on the inner flange. The standard section 111 with an inner flange can ensure that the gap between the threaded sleeve 140, the central through hole of the platform truss 150 and the central column 110 is small, thereby avoiding excessive gaps that affect the stability and reliability of the rotation and lifting of the platform truss 150 and the threaded sleeve 140 relative to the central column 110.

[0076] The internal construction platform 100 of the silo provided by the embodiment of the present invention changes the installation and removal of the platform truss 150 from high altitude to the silo ground, thereby improving the safety and ease of construction workers in disassembling and assembling the platform truss 150, and can avoid the safety hazard of falling from high altitude when disassembling and assembling the platform truss at high altitude. The platform truss has the advantages of convenient disassembly and assembly, high safety and high efficiency.
