The first spring plays a role of assisting the resetting of the connecting plate, and the limiting guide sleeve also has the function of assisting the movement of the connecting plate itself when the connecting plate moves.

The connecting rod plays a fixing role. At the same time, the connection of the connecting rod further improves the force distribution of the second fixed base to make the force more uniform during use, which can further improve the stability of the device. When disassembly is required, the button drives the third spring to drive the firing push rod, so that the arched spring piece pops down into the inside of the shell, thereby driving the connecting rod to rebound through the second spring, which plays a role of quick disassembly during use, improves the installation convenience of the device during use, and can be disassembled for easy transportation.

[0015] The present invention provides a method and device for dismantling a construction platform inside a silo, which has the following beneficial effects: 1.

At the same time, the lifting component drives the second fixed base to rise synchronously during the rising process, which has the effect of improving the safety and working space during high-altitude operations.

[0016] 2.

[0027] A method for dismantling a construction platform inside a silo comprises the following steps: After the platform support column 1 is built, the first fixed base 3 is first laid around the platform support column 1 and circled for a circle, and during the process, ensure that the bottom of the first fixed base 3 is as flat as possible and does not shake, then slide the second connecting block 7 into the inside of the slide groove 5 through the gap at the connection of the first fixed base 3, and then slide the first connecting block 6 in, then slide the second connecting block 7 into the inside of the first connecting block 6, and by rotating the bolt 9, when the arched folding plate 8 conflicts with the first connecting block 6, pull the second connecting block 7 to move up inside the first fixed base 3 and the first connecting block 6, so that the first connecting block 6 is locked and fixed during use, so that the first fixed base 3 is fixed after docking, and then at this time, the construction platform body 2 is disassembled during use by connecting the hoisted end of the winch 11 to the construction platform body 2; The cross bar 16 is inserted into the interior of the limiting guide sleeve 12 and connected and installed through the flange 17, and then the second fixed base 4 is sleeved on the outer wall of the cross bar 16. The second fixed base 4 can be used as a platform during use, which can improve the safety of high-altitude operations during use. At the same time, it provides a safe platform for workers and protects the platform support column 1 and the construction platform body 2. The second hydraulic cylinder 34 drives the connecting plate 15 to move under the limit of the rotating block 35, and drives the first spring 18 to slide on the outer wall of the cross bar 16. The first spring 18 plays a role in assisting the resetting of the connecting plate 15, and the limiting guide sleeve 12 also has the function of assisting the movement of the connecting plate 15 itself when the connecting plate 15 moves. The role of limiting the position of the second meshing tooth plate 14 and the first meshing tooth plate 13 is ensured, and the stability of the second meshing tooth plate 14 and the first meshing tooth plate 13 when they are meshed is ensured. When rising, the second hydraulic cylinder 34 at the bottom is first started to drive the connecting plate 15 to move and mesh with the first meshing tooth plate 13 under the limit of the rotating block 35, and then it plays a fixing role. Then, the upper support platform 20 is driven to rise by starting the first hydraulic cylinder 22, and then the connecting plate 15 is driven to move by starting the second hydraulic cylinder 34 on the upper side, and then the first hydraulic cylinder 22 is retracted, and the second hydraulic cylinder 34 on the lower side is moved to drive the crankshaft 19 and the gear 21 to make the connecting plates 15 on both sides move synchronously, thereby playing a step-by-step rising role in use. At the same time, the second fixed base 4 can be driven to rise and fall through the cross bar 16, and a safe working platform can be provided for workers during use. The cross bar 16 is inserted into the mounting groove 25 and the interior of the third connecting block 23, and the two third connecting blocks 23 are aligned to allow the connecting rod 26 to pass through the two third connecting blocks 23, which plays a fixing role during use. After the two third connecting blocks 23 are connected, the connecting rod 26 is pressed to drive the locking ring 29 to slide into the interior of the shell 31, and then it is stuck. The connecting rod 26 plays a fixing role. At the same time, the connection of the connecting rod 26 further improves the distribution of force by the second fixed base 4 to make the force more uniform during use, which can further improve the stability of the device. When disassembly is required, the button 33 drives the third spring 32 to drive the firing push rod, so that the arched spring piece 30 pops out downward from the interior of the shell 31, thereby driving the connecting rod 26 to rebound through the second spring 28, which plays a role of quick disassembly during use, improves the installation convenience of the device during use, and can be disassembled for easy transportation.

[0028] Specifically, during the installation process, the second connecting block 7 is slid into the inside of the slide groove 5 by utilizing the slide groove 5, and the first connecting block 6 is slid in to form a connection with the second connecting block 7. By rotating the bolt 9, when the arched folding plate 8 contacts the first connecting block 6, the first connecting block 6 is moved up and fixed inside the first fixed base 3 with the help of the pulling action of the second connecting block 7. This process ensures the stability of the device and locks the first fixed base 3. During use, it plays an effect of quickly installing and splicing the first fixed base 3, further reducing the difficulty of installing the device during use. The first fixed base 3 that can be disassembled during use can also be more conveniently transported during transportation, which can reduce transportation costs. Therefore, it is not easy to install, the structure is simple, and it can be quickly installed, disassembled and replaced during use. The installation requirements are not high, and the detachable structure can also reduce transportation costs during transportation. The winch 11 is used to lift and connect to the construction platform body 2, so that during the dismantling process, the stability of the construction platform can be controlled and the dismantling of the temporary support column and the construction platform can be completed. The second hydraulic cylinder 34 drives the second fixed base 4 to move under the action of the rotating block 35, and the cross bar 16 is inserted into the inside of the limiting guide sleeve 12, and the flange 17 is matched for rapid installation, and can be used as a working platform. The second fixed base 4 not only provides a stable working platform to ensure the safety of construction workers, but also provides additional protection for the platform support column 1 and the construction platform body 2 during the dismantling process. The movement of the connecting plate 15 is driven by limiting, so as to ensure the stable engagement between the first meshing tooth plate 13 and the second meshing tooth plate 14. The upper and lower groups of the first meshing tooth plates 13 and the second meshing tooth plates 14 are used alternately. During use, the synchronous lifting and lowering of the lifting platform is driven, so as to ensure the stability of the operation process and provide an aerial work platform, so that the workers have higher safety when working at high altitudes. During use, the two third connecting blocks 23 are connected to each other, so as to achieve the effect of synchronously distributing the load-bearing capacity of the cross bar 16. Through the connection of the third connecting block 23, not only can the height adjustment process have better synchronization, but also the weight can be evenly distributed to prevent accidents caused by excessive weight on one side of the device.

10. A method for dismantling a construction platform inside a silo, applied to a device for dismantling a construction platform inside a silo according to any one of claims 1 to 9, characterized in that: The following steps are involved: After the platform support column (1) is built, the first fixed base (3) is first laid around the platform support column (1) and surrounds it for a circle, and during the process, ensure that the bottom of the first fixed base (3) is as flat as possible and does not shake. At this time, the second connecting block (7) is slid into the inside of the slide groove (5) through the gap at the connection of the first fixed base (3), and then the first connecting block (6) is slid in. At this time, the second connecting block (7) is slid into the inside of the first connecting block (6), and the second connecting block (7) is pulled upward inside the first fixed base (3) and the first connecting block (6) by rotating the bolt (9) when the arched folding plate (8) contacts the first connecting block (6), so that the first connecting block (6) is locked and fixed during use, so that the first fixed base (3) is fixed after docking, and then the construction platform body (2) is disassembled during use by connecting the hoisted end of the winch (11) to the construction platform body (2); The cross bar (16) is inserted into the interior of the limiting guide sleeve (12) and connected and installed through the flange (17), and then the second fixed base (4) is sleeved on the outer wall of the cross bar (16). The second fixed base (4) can be used as a platform during use, which can improve the safety of high-altitude operations during use, and at the same time provide a safe platform for workers, and protect the platform support column (1) and the construction platform body (2). The second hydraulic cylinder (34) drives the connecting plate (15) to move under the limit of the rotating block (35), and drives the first spring (18) to slide on the outer wall of the cross bar (16). The first spring (18) plays a role in assisting the resetting of the connecting plate (15), and the connecting plate (15) also has the function of assisting the movement of the connecting plate (15) itself through the limiting guide sleeve (12) when the connecting plate (15) moves. The function of limiting the position ensures the stability of the second meshing tooth plate (14) and the first meshing tooth plate (13) when they are meshed. When ascending, the second hydraulic cylinder (34) at the bottom is first started to drive the connecting plate (15) to move and mesh with the first meshing tooth plate (13) under the limit of the rotating block (35). At this time, it plays a fixing role. Then, the upper support platform (20) is driven to rise by starting the first hydraulic cylinder (22). Then, the connecting plate (15) is driven to move by starting the second hydraulic cylinder (34) on the upper side. Then, the first hydraulic cylinder (22) is retracted, and the second hydraulic cylinder (34) on the lower side is moved to drive the crankshaft (19) and the gear (21) to make the connecting plates (15) on both sides move synchronously, thereby playing a step-by-step ascending role in use. At the same time, the second fixed base (4) can be driven to rise and fall through the cross bar (16). During use, a safe working platform can be provided for workers. The cross bar (16) is inserted into the installation groove (25) and the interior of the third connecting block (23), and the two third connecting blocks (23) are aligned so that the connecting rod (26) passes through the two third connecting blocks (23), which plays a fixing role during use. After the two third connecting blocks (23) are connected, the connecting rod (26) is pressed to drive the locking ring (29) to slide into the interior of the casing (31) and then locked. The connecting rod (26) plays a fixing role. At the same time, the connection of the connecting rod (26) further improves the distribution of force by the second fixed base (4) to make the force more uniform during use, which can further improve the stability of the device. When disassembly is required, the button (33) drives the third spring (32) to drive the firing push rod, so that the arched spring piece (30) pops out of the interior of the casing (31), so that the second spring (28) drives the connecting rod (26) to rebound, which plays a role of quick disassembly during use, improves the convenience of installation of the device during use, and can be disassembled for easy transportation.
