Description

Technical Field

[0001] This invention relates to the field of silo conical shell installation technology, specifically to an attached lifting silo conical shell steel truss structure umbrella-shaped support system and construction method. Background Technology

[0002] Warehouses for storing bulk materials. They are broadly classified into agricultural silos and industrial silos. Agricultural silos are used to store granular and powdery materials such as grains and feed; industrial silos are used to store bulk materials such as coke, cement, salt, and sugar. Mechanized silos generally cost about one-third more than mechanized modular warehouses, but they shorten the material loading and unloading process, reduce operating and maintenance costs, eliminate arduous bagging operations, and facilitate mechanized and automated operations. Therefore, they have become one of the most important forms of grain storage.

[0003] Currently, after the silo is constructed, the silo cone shell needs to be transported to the top of the silo for installation. The current method of transporting the silo cone shell is mostly to use truck cranes or electric hoists for hoisting. Since truck cranes or electric hoists lift the silo cone shell through cables, the silo cone shell is very prone to shaking during the lifting process. In addition, many secondary structures and embedded parts caused by the slipform process on the silo wall need to be removed by workers later. However, there is no operating platform inside the silo for workers to carry out construction operations, which poses certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide an attached lifting silo conical shell steel truss structure umbrella-shaped support system and construction method, aiming to solve the problems in the existing technology where the conveying of silo conical shells mostly uses truck cranes or electric hoists for hoisting. Since truck cranes or electric hoists lift the silo conical shell through cables, the silo conical shell is prone to shaking during the lifting process. In addition, many secondary structures and embedded parts caused by the slipform process on the silo wall need to be removed by workers later. Moreover, there is no operating platform inside the silo for workers to carry out construction operations, which poses certain safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An attached lifting silo conical shell steel truss structure umbrella-shaped support system includes a silo body; a lifting operating platform: disposed within the silo body, capable of lifting and lowering along the height direction of the silo body, and used to support the silo conical shell, the silo conical shell can be placed on the lifting operating platform, the lifting operating platform can drive the silo conical shell to rise when it rises, and can also serve as an operating platform for workers to perform construction operations; several guide parts: disposed on the inner wall of the silo body, and arranged in an equidistant circular array around the axis of the silo body, guiding... The movable end of the unit is fixedly connected to the lifting operating platform, serving to guide and install the lifting operating platform; several sets of tiered drive units are set on the inner wall of the silo body, with each set of tiered drive units arranged at equal distances along the height direction of the silo body, and every two adjacent sets of tiered drive units are staggered along the inner wall of the silo body, driving the lifting operating platform to move up and down through tiered conveying; several load-bearing parts are respectively set on each tiered drive unit, used to support and limit the lifting operating platform, and the tiered drive units can drive the lifting operating platform to move up and down through the load-bearing parts.

[0006] A further technical solution of the present invention is that each set of staged drive units includes a number of slide rails arranged at equal distances around the axis of the silo body. Every two adjacent slide rails are staggered along the inner wall of the silo body. Each slide rail is slidably connected to a slider, and the load-bearing part is set on the slider. Each slider is threadedly connected to a lead screw, and the two ends of the lead screw are respectively rotatably connected to the inner top wall and inner bottom wall of the slide rail.

[0007] A further technical solution of the present invention is that the load-bearing part includes several fixed frames respectively mounted on the slider. A first slide plate is slidably connected inside the fixed frame. A load-bearing column is installed on the side of the first slide plate away from the slider, and the end of the load-bearing column away from the first slide plate extends to the outside of the fixed frame. When the load-bearing column slides toward the fixed frame, the load-bearing column can move into the inside of the fixed frame, so that the fixed frame can accommodate the load-bearing column. When the load-bearing column is outside the fixed frame, the load-bearing column is used to support the lifting operating platform. When the load-bearing column is inside the slide rail, the lifting operating platform can pass in front of the load-bearing column, and the load-bearing column cannot limit or support the lifting operating platform. A round head is fixedly connected to the end of the load-bearing column away from the first slide plate. Both the surface of the load-bearing column and the round head are provided with a slope.

[0008] A further technical solution of the present invention is that a guide drive unit is provided inside the fixed frame.

[0009] A further technical solution of the present invention is that the guide drive unit includes a cavity opened in the load-bearing column, a second slide plate is slidably connected in the cavity, two connecting rods are fixedly connected to the side of the second slide plate near the first slide plate, and the connecting rods pass through the first slide plate and extend to the other side of the first slide plate, a turntable is fixedly connected to the end of the two connecting rods away from the second slide plate, and the connecting rods are rotatably connected to the inner wall of the fixed frame, and an elastic reset member is sleeved on both connecting rods, and the two ends of the elastic reset member are fixedly connected to the first slide plate and the turntable respectively.

[0010] A further technical solution of the present invention is that the elastic reset element is a compression spring.

[0011] A further technical solution of the present invention is that the guide part includes a plurality of guide rails arranged at equal distances around the axis of the silo body, and the guide rails are fixed on the inner wall of the silo body. Each guide rail is slidably connected to an installation block, and the installation block is fixedly connected to the lifting operating platform.

[0012] This invention provides a construction method for an attached lifting silo conical shell steel truss structure umbrella-shaped support system, comprising the following steps: Step 1: First, install the guide unit on the inner wall of the silo body by pre-embedding it, and connect the lifting operating platform to the guide unit; Step 2: When it is necessary to lift the silo cone shell, move the lifting platform to the lowest level of the stage drive unit, place the silo cone shell on the lifting platform, and use the load-bearing part on the stage drive unit to support and limit the lifting platform. Step 3: Connect the next level of the grading drive unit to an external power source. Drive the grading drive unit simultaneously through the external power source, so that the grading drive unit drives the lifting operating platform to move upward. When the load-bearing part on the next level grading drive unit moves to the position that coincides with the load-bearing part on the previous level grading drive unit, the load-bearing part on the previous level grading drive unit can support and limit the lifting operating platform. Step 4: Next, connect the previous level of the graded drive unit to the external power source. The external power source drives the graded drive unit to move the lifting platform upward. This process is repeated to move the lifting platform upward. Step 5: When the lifting platform moves to the top of the silo body and needs to move downward, connect the upper-level grading drive unit to the external power source. The external power source drives the grading drive unit to move downward. Step Six: When the load-bearing part on the upper-level grading drive unit moves to a position that overlaps with the load-bearing part on the lower-level grading drive unit, connect the load-bearing part on the upper-level grading drive unit to an external power source, causing the load-bearing part to rotate 180 degrees. The load-bearing part on the upper-level grading drive unit will then be unable to support or limit the lifting operation platform. At this time, the load-bearing part on the lower-level grading drive unit can support and limit the lifting operation platform. Step 7: Then connect the next level of the graded drive unit to the external power source. The external power source drives the graded drive unit to move the lifting platform downwards. This process is repeated to drive the lifting platform to descend.

[0013] The beneficial effects of this invention are: 1. When lifting the silo cone shell, move the lifting platform to the lowest level of the stage drive unit, place the silo cone shell on the lifting platform, and use the load-bearing parts on the stage drive unit to support and limit the lifting platform. Connect the next stage drive unit to an external power source, and drive the stage drive unit simultaneously to move the lifting platform upward. When the load-bearing parts on the next stage drive unit move to the same position as the load-bearing parts on the previous stage drive unit, the load-bearing parts on the previous stage drive unit can then support and limit the lifting platform. Next, connect the previous stage drive unit to an external power source, and drive the stage drive unit simultaneously to move the lifting platform upward. This process is repeated to drive the lifting platform upward. This allows for convenient lifting of the silo cone shell, effectively improves its stability, and facilitates easier installation.

[0014] 2. When the lifting platform moves to the top of the silo body and needs to move downwards, connect the upper-level grading drive unit to an external power source. The external power source drives the grading drive unit simultaneously, causing it to drive the lifting platform downwards. When the load-bearing part on the upper-level grading drive unit moves to a position coinciding with the load-bearing part on the lower-level grading drive unit, connect the load-bearing part on the upper-level grading drive unit to the external power source, causing the load-bearing part to rotate. This prevents the load-bearing part on the upper-level grading drive unit from supporting the lifting platform. The load-bearing part on the next-level stage drive unit can then bear the weight and limit the movement of the lifting platform. The next-level stage drive unit is then connected to an external power source, which drives the stage drive unit to move the lifting platform downwards. This process is repeated to lower the lifting platform, thus supporting the worker and allowing them to move up and down. This enables workers to perform construction operations on the inner wall of the silo, effectively improving the efficiency of removing secondary structures and embedded parts caused by the slipform process.

[0021] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-5As shown, an attached lifting silo conical shell steel truss structure umbrella-shaped support system includes a silo body 1. Inside the silo body 1 is a lifting platform 2 that can be raised and lowered along the height direction of the silo body 1. The conical shell of the silo can be placed on the lifting platform 2. When the lifting platform 2 rises, it can drive the conical shell of the silo to rise as well, thereby transporting the conical shell to the top of the silo for installation. It also serves as an operating platform for workers to perform construction operations. The inner wall of the silo body 1 is provided with several sets of guide parts 3 arranged in a circumferential array at equal intervals around the axis of the silo body 1. The movable ends of the guide parts 3 are fixedly connected to the lifting platform 2, serving to guide and install the lifting platform 2, allowing the lifting platform 2 to move during lifting... To prevent tilting or shifting, the inner wall of the silo body 1 is provided with several sets of graded drive units 4. Each set of graded drive units 4 is arranged at equal distances along the height direction of the silo body 1. Every two adjacent graded drive units 4 are staggered along the inner wall of the silo body 1. The graded drive units 4 drive the lifting platform 2 to rise and fall through the graded conveying method, thereby conveying the silo cone shell to the top of the silo. This lifting method can effectively improve the stability of the lifting platform 2, allowing workers to carry out construction operations more safely and conveniently. Each graded drive unit 4 is provided with a load-bearing part 5, which is used to support and limit the lifting platform 2. When the graded drive unit 4 rises and falls, the load-bearing part 5 drives the lifting platform 2 to rise and fall.

[0023] like Figure 1-3 As shown, each set of tiered drive units 4 includes several slide rails 41 arranged at equal distances around the axis of the silo body 1. Every two adjacent slide rails 41 are staggered along the inner wall of the silo body 1. Each slide rail 41 is slidably connected to a slider 42, and a load-bearing part 5 is set on the slider 42. Each slider 42 is threadedly connected to a lead screw 43, and the two ends of the lead screw 43 are rotatably connected to the inner top wall and inner bottom wall of the slide rail 41, respectively. By connecting the lead screws 43 of the same set to an external power source, the external power source can simultaneously drive each lead screw 43 to rotate, thereby driving the slider 42 to rise along the height direction of the slide rail 41. The rise of the slider 42 can drive the load-bearing part 5 to rise and fall, thereby driving the silo cone shell to rise.

[0024] like Figure 4 and Figure 5As shown, the load-bearing part 5 includes several fixed frames 51 respectively mounted on the slider 42. A first slide plate 52 is slidably connected inside the fixed frame 51. A load-bearing column 53 is installed on the side of the first slide plate 52 away from the slider 42, and the end of the load-bearing column 53 away from the first slide plate 52 extends to the outside of the fixed frame 51. When the load-bearing column 53 slides toward the fixed frame 51, the load-bearing column 53 can move into the interior of the fixed frame 51, so that the fixed frame 51 accommodates the load-bearing column 53. When the load-bearing column 53 is outside the fixed frame 51, the load-bearing column 53 is used to support the lifting platform 2. When the load-bearing column 53 is inside the slide rail 41, the lifting platform 2 can pass in front of the load-bearing column 53, and the load-bearing column 53 can no longer limit or support the lifting platform 2. The end of the load-bearing column 53 away from the first slide plate 52 is fixedly connected to a round head 54. Both the surface of the load-bearing column 53 and the round head 54 are provided with an inclined surface. When the lifting operating platform 2 squeezes the load-bearing column 53 and the round head 54 through the inclined surface, it can easily squeeze the load-bearing column 53 into the fixed frame 51. After the next level of the graded drive unit 4 drives the load-bearing column 53 of the same level to rise, the lifting operating platform 2 on the load-bearing column 53 moves to contact the load-bearing column 53 of the previous level, and can squeeze the load-bearing column 53 of the previous level to move into the fixed frame 51. Then the lifting operating platform 2 continues to move, and the load-bearing column 53 of the previous level extends out from the fixed frame 51, so that it can support the lifting operating platform 2. This process is repeated to realize the graded conveying of the lifting operating platform 2. The fixed frame 51 is equipped with a guide drive unit. When the load-bearing column 53 moves into the fixed frame 51, it can automatically push the load-bearing column 53 out of the fixed frame 51 to support the lifting platform 2. It can also drive the load-bearing column 53 and the round head 54 to rotate, so that the inclined surfaces of the load-bearing column 53 and the round head 54 can rotate to a suitable direction, which facilitates the lifting platform 2 to lift. The guide drive unit includes a cavity 55 formed within the load-bearing column 53. A second slide plate 56 is slidably connected within the cavity 55. Two connecting rods 57 are fixedly connected to the side of the second slide plate 56 closest to the first slide plate 52, and the connecting rods 57 pass through the first slide plate 52 and extend to the other side of the first slide plate 52. A turntable 58 is fixedly connected to the end of each connecting rod 57 away from the second slide plate 56, and the connecting rods 57 are rotatably connected to the inner wall of the fixed frame 51. Each connecting rod 57 is fitted with an elastic reset member 59, and both ends of the elastic reset member 59 are fixedly connected to the first slide plate 52 and the turntable 58, respectively. The elastic reset member 59 is a compression spring. The turntable 58 is connected to an external power source, and then the turntable 58 is rotated. The rotation of the turntable 58 drives the first slide plate 52 to rotate via the connecting rods 57. Then, the rotation of the first slide plate 52 drives the load-bearing column 53 and the round head 54 to rotate, causing the load-bearing column 53 and the round head 54 to rotate. With the inclined surfaces in a suitable orientation, when the lifting platform 2 rises, all the inclined surfaces on the load-bearing columns 53 and round heads 54 are driven by the turntable 58 to face the lifting platform 2. When the lifting platform 2 descends, all the inclined surfaces on the load-bearing columns 53 and round heads 54 are driven by the turntable 58 to face away from the lifting platform 2. When the upper-level graded drive unit 4 moves the load-bearing columns 53 and round heads 54 downwards until they coincide with the load-bearing columns 53 and round heads 54 of the lower-level graded drive unit 4, the turntable 58 drives the load-bearing columns 53 and round heads 54 of the upper-level graded drive unit 4 to rotate, causing the inclined surfaces on the upper-level load-bearing columns 53 and round heads 54 to rotate so that they face the lifting platform 2. The lifting platform 2 can then disengage from the upper-level load-bearing columns 53 and round heads 54. The lower-level graded drive unit 4 continues to drive the lifting platform 2 to descend, and so on, thus driving the lifting platform 2 to move downwards.

[0025] like Figure 1 and Figure 2 As shown, the guide section 3 includes several guide rails 31 arranged at equal distances around the axis of the silo body 1, and the guide rails 31 are fixed on the inner wall of the silo body 1. Each guide rail 31 is slidably connected to a mounting block 32, and the mounting block 32 is fixedly connected to the lifting operating platform 2. When the lifting operating platform 2 is raised or lowered, it can effectively play the role of mounting and guiding the lifting operating platform 2, making it easier to raise and lower the lifting operating platform 2.

[0026] This invention provides a construction method for an attached lifting silo conical shell steel truss structure umbrella-shaped support system, comprising the following steps: Step 1: First, install the guide part 3 on the inner wall of the silo body 1 by pre-embedding, and connect the lifting operating platform 2 to the guide part 3; Step 2: When it is necessary to lift the silo cone shell, move the lifting platform 2 to the lowest level of the stage drive unit 4, place the silo cone shell on the lifting platform 2, and use the load-bearing part 5 on the stage drive unit 4 to support and limit the lifting platform 2. Step 3: Connect the next-level grading drive unit 4 to an external power source. Drive the grading drive unit 4 simultaneously through the external power source, so that the grading drive unit 4 drives the lifting platform 2 to move upward. When the load-bearing part 5 on the next-level grading drive unit 4 moves to a position that coincides with the load-bearing part 5 on the previous-level grading drive unit 4, the load-bearing part 5 on the previous-level grading drive unit 4 can support and limit the lifting platform 2. Step 4: Next, connect the previous level grading drive unit 4 to an external power source. The external power source drives the grading drive unit 4 to drive the lifting operating platform 2 to move upward. This process is repeated to drive the lifting operating platform 2 to move upward. Step 5: When the lifting platform 2 moves to the top of the silo body 1 and needs to move downward, connect the upper-level grading drive unit 4 to the external power source. The external power source drives the grading drive unit 4 to drive the lifting platform 2 downward. Step Six: When the load-bearing part 5 on the upper-level grading drive unit 4 moves to a position that overlaps with the load-bearing part 5 on the lower-level grading drive unit 4, connect the load-bearing part 5 on the upper-level grading drive unit 4 to an external power source, causing the load-bearing part 5 to rotate 180 degrees. The load-bearing part 5 on the upper-level grading drive unit 4 will then be unable to support and limit the lifting operating platform 2. At this time, the load-bearing part 5 on the lower-level grading drive unit 4 can support and limit the lifting operating platform 2. Step 7: Then connect the next level of the graded drive unit 4 to the external power source. The external power source drives the graded drive unit 4 to drive the lifting platform 2 to move downwards. This process is repeated to drive the lifting platform 2 to descend.

[0027] Working principle: When the silo cone shell needs to be lifted, the lifting platform 2 is moved to the lowest level stage drive unit 4, and the silo cone shell is placed on the lifting platform 2. The load-bearing part 5 on the stage drive unit 4 provides load support and limits the lifting platform 2. The next stage stage drive unit 4 is connected to an external power source, and the external power source drives the stage drive unit 4 to move the lifting platform 2 upward. When the load-bearing part 5 on the next stage stage drive unit 4 moves to a position that coincides with the load-bearing part 5 on the previous stage stage drive unit 4, the lifting platform 2 moves upward. At this time, the load-bearing part 5 on the upper-level stage drive unit 4 can bear the weight and limit the lifting platform 2; then, the upper-level stage drive unit 4 is connected to an external power source, and the external power source drives the stage drive unit 4 to drive the lifting platform 2 upward, and so on, to drive the lifting platform 2 upward; thus, the silo cone shell can be lifted conveniently, and the stability of the silo cone shell can be effectively improved, making it easier to install. When the lifting platform 2 moves to the top of the silo body 1, When downward movement is required, the upper-level grading drive unit 4 is connected to an external power source. The external power source drives the grading drive unit 4, causing it to simultaneously drive the lifting platform 2 downwards. When the load-bearing part 5 on the upper-level grading drive unit 4 moves to a position coinciding with the load-bearing part 5 on the lower-level grading drive unit 4, the load-bearing part 5 on the upper-level grading drive unit 4 is connected to the external power source, causing it to rotate 180 degrees. This prevents the load-bearing part 5 on the upper-level grading drive unit 4 from supporting and limiting the lifting platform 2. The load-bearing part 5 on the first-level graded drive unit 4 can then bear weight and limit the lifting platform 2. Then, the next-level graded drive unit 4 is connected to an external power source. The external power source drives the graded drive unit 4 to move the lifting platform 2 downward. This process is repeated to drive the lifting platform 2 to descend. Thus, the lifting platform 2 supports the worker and moves them up and down, enabling the worker to carry out construction operations on the inner wall of the silo. This effectively improves the efficiency of removing secondary structures and embedded parts caused by the slipform process.

When the load-bearing part (5) on the next level graded drive unit (4) moves to the position where it overlaps with the load-bearing part (5) on the previous level graded drive unit (4), the load-bearing part (5) on the previous level graded drive unit (4) can support and limit the lifting platform (2). Step 4: Next, connect the upper-level graded drive unit (4) to the external power source. Drive the graded drive unit (4) simultaneously through the external power source, so that the graded drive unit (4) drives the lifting platform (2) to move upward. Repeat this process to drive the lifting platform (2) to move upward. Step 5: When the lifting platform (2) moves to the top of the silo body (1) and needs to move downward, connect the upper-level grading drive unit (4) to the external power source. Drive the grading drive unit (4) through the external power source to drive it, so that the grading drive unit (4) drives the lifting platform (2) to move downward. Step 6: When the load-bearing part (5) on the upper-level graded drive unit (4) moves to a position that overlaps with the load-bearing part (5) on the lower-level graded drive unit (4), connect the load-bearing part (5) on the upper-level graded drive unit (4) to an external power source, so that the load-bearing part (5) is rotated 180 degrees. The load-bearing part (5) on the upper-level graded drive unit (4) can no longer support and limit the lifting platform (2). At this time, the load-bearing part (5) on the lower-level graded drive unit (4) can support and limit the lifting platform (2). Step 7: Then connect the next level of the graded drive unit (4) to the external power source. Drive the graded drive unit (4) simultaneously through the external power source, so that the graded drive unit (4) drives the lifting platform (2) to move downward. Repeat this process to drive the lifting platform (2) to descend.
