Description

Technical Field

[0001] This invention relates to the field of shallow circular silo technology, specifically to an airbag-type assembled shallow circular silo lifting device and its lifting method. Background Technology

[0002] Grain silos are important facilities for ensuring food security and emergency reserves. In the development of modern grain storage construction, shallow circular silos are widely used due to their small footprint, strong earthquake resistance, reasonable structural stress, and good sealing performance. Shallow circular silos refer to cylindrical above-ground grain silos with a height-to-width ratio of less than 1.5. They are mostly made of concrete and their diameter is generally between 18 and 35 meters.

[0003] The existing construction technology for shallow circular silos is slipform construction, which involves pouring concrete, curing, and climbing simultaneously. This technology has advantages such as high mechanization and high safety, which has greatly promoted the construction of shallow circular silos. However, slipform construction is affected by the rainy season, and once construction begins, it requires 24-hour manual labor, and the daily construction height is also limited. Summary of the Invention

[0004] The purpose of this invention is to provide an airbag-type assembled shallow circular silo lifting device and its lifting method to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An airbag-type prefabricated shallow circular compartment lifting device includes an airbag and a stress-bearing cloth covering the airbag;

[0007] The airbag is connected to an inflation mechanism and is cylindrical after inflation. The stress-bearing cloth is provided with annular steel wires and stress-bearing steel wires. The end of the stress-bearing steel wire is provided with a bolt sleeve. The bolt sleeve is adapted to the bolts provided on the bin wall plate. The outer periphery of the airbag is provided with a limiting mechanism.

[0008] The limiting mechanism includes a ring beam, which includes four arc-shaped I-beams. Adjacent arc-shaped I-beams are fixedly connected to each other by ring beam bolts and washers. The ring beam is provided with a first slot and a first bolt hole. The first slot is adapted to be fitted with a plug-in component. The plug-in component can be embedded into the first slot and a niche provided on the inner side of the warehouse wall panel.

[0009] The ring beam cooperates with multiple sets of support mechanisms, which are equidistantly distributed along the circumference of the ring beam. Each support mechanism includes a support column with a support rib inside and a second bolt hole at the bottom for connecting to the ground. The lower part of the ring beam can be connected to a ring beam support on the support column via ring beam bolts. The ring beam support can slide along the support column via a second latch on the support column.

[0010] As a further aspect of the present invention, the inflation mechanism is a high-pressure air pump.

[0011] As a further embodiment of the present invention: the inflation mechanism includes a base, and further includes:

[0012] A transverse plate is movably mounted on the base and connected to a threaded drive assembly mounted on the base. The threaded drive assembly can drive the transverse plate to move along the length direction of the base. A pumping assembly is mounted on the transverse plate and is triggered when the transverse plate moves.

[0013] A pipeline switching assembly is mounted on the transverse plate and connected to an elastic trigger assembly mounted on the transverse plate. The elastic trigger assembly is triggered at the end of the transverse plate's travel distance and can cause the pipeline switching assembly to move.

[0015] The base is also equipped with a drive motor, the output end of which is connected to the lead screw. The transverse plate is fixedly connected to the threaded sleeve and the guide sleeve. The threaded sleeve is threadedly connected to the lead screw, and the guide sleeve is slidably connected to the guide rod.

[0016] As a further embodiment of the present invention: the air pumping assembly includes a cylinder fixedly installed on the transverse plate, a piston disc slidably disposed inside the cylinder, and a crossbar fixedly connected to the piston disc via a column, the crossbar cooperating with a circumferential rotating structure installed on the outer wall of the cylinder.

[0017] As a further embodiment of the present invention: the circumferential rotating structure includes a disc rotatably mounted on the cylinder and a column fixed at the eccentric position of the disc, and the crossbar is provided with a through groove adapted to the column, the column passing through the through groove and being slidably connected to the crossbar;

[0018] A gear is rotatably mounted on the cylinder, the gear meshes with a rack plate fixedly mounted on the base, and a transmission belt connects the rotation shafts of the gear and the disc.

[0019] As a further embodiment of the present invention: the pipeline switching assembly includes two first pipe fittings connected to the cylinder and two second pipe fittings fixed on the cylinder, the two first pipe fittings and the two second pipe fittings being arranged opposite to each other, and a first one-way valve, a third one-way valve, a second one-way valve, and a fourth one-way valve being respectively installed on the two first pipe fittings;

[0020] A first guide plate and a second guide plate are fixed on the outer wall of the cylinder. The elastic triggering component is installed on the first guide plate. A horizontal plate connected to the elastic triggering component is slidably provided on the second guide plate. The horizontal plate is provided with two through holes. The horizontal plate is located between the first pipe and the second pipe and is slidably connected to the first pipe and the second pipe. The airbag is connected to the second pipe corresponding to the first one-way valve and the third one-way valve.

[0021] As a further embodiment of the present invention: the elastic triggering component includes an assembly cylinder slidably disposed on the first guide plate and a telescopic rod slidably fitted with the assembly cylinder. The telescopic rod is fixed to a ring body slidably disposed inside the assembly cylinder, and a first columnar spring and a second columnar spring are fitted around the outer periphery of the telescopic rod. The first end of the first columnar spring and the second columnar spring are connected to the ring body, and the tail end abuts against the inner wall of the assembly cylinder.

[0022] One end of the telescopic rod is connected to the horizontal plate via a connecting rod. The two ends of the connecting rod are respectively hinged to the telescopic rod and the horizontal plate. A limiting plate is also fixed on the base. The limiting plate has a rectangular groove and an inclined groove. The other end of the telescopic rod extends into the rectangular groove and is slidably connected to the limiting plate. A protruding post is fixed on the assembly cylinder. The protruding post extends into the inclined groove and is slidably connected to the limiting plate.

[0023] A method for lifting a prefabricated shallow circular silo using an airbag-type assembly, employing the aforementioned lifting device, includes the following steps:

[0024] Step 1: Drill bolt holes in the ground, then clip the ring beam bracket onto the second slot, then erect the support column and fix the support column to the ground through the second bolt hole and bolts;

[0025] Step 2: Place the four ring beams on the ring beam support and fix them with ring beam bolts. The insert can be embedded in the first slot, and the first bolt hole is used to fix the ring beam to the ring beam support with bolts.

[0026] Step 3: Place the airbag and cover it with the stress-bearing cloth;

[0027] Step 4: Place a ring of silo wall panels, insert bolts into the upper inner niches of the silo wall panels, fit the bolt sleeves on the top of the bolts onto the upper side of the bolts, and then construct the silo roof.

[0028] Step 5: Inspect the bolt sleeve and insert the plug into the lower niche of the silo wall panel. Use a high-pressure air pump to inflate the airbag. After the airbag is inflated, it lifts the upper stress cloth and transmits the tension through its stress wire to the bolts connected to the silo wall panel, causing the silo wall panel to rise.

[0029] Step 6: Remove the first layer of plug-in parts, slide the ring beam down to the height of the niche on the lower side of the second layer of warehouse wall, insert the plug-in parts into the first slot and the niche on the lower part of the second layer of warehouse wall panel to restrict the direction of movement when the second layer of warehouse wall panel is lifted, and use a high-pressure air pump to inflate the airbag to lift the second layer of warehouse wall panel.

[0030] Step 7: Repeat the jacking, assembling of prestressed tendons and bolts for the silo wall panels, removing and replacing the inserts for the next layer, and jacking again, until all the 10 layers of shallow circular silo wall panels are assembled.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. In specific implementation, after the first horizontal arrangement of the silo wall panels, tensioning of prestressed steel bars, bolt fixing, and construction of the silo roof above, the bolt sleeves on the stress-bearing cloth are fitted onto the upper bolts of the first layer. The inserts in the limiting beam are embedded into the niches of the silo wall panels. Then, a high-pressure air pump is used to inflate the airbags, which lift the stress-bearing cloth. The bolts connected by the bolt sleeves of the steel wire ropes in the stress-bearing cloth drive the silo wall panels to rise. Due to the presence of the limiting device, the silo wall panels will only move in the vertical direction. After being lifted to a height suitable for assembling the next layer of silo wall panels, the next layer of silo wall panels is assembled. Then, the inserts from the previous layer are removed and placed into the next layer to restrict their position. The airbags are inflated and lifted until all silo wall panels are assembled. Therefore, the prefabricated construction is optimized, the construction period is shorter, labor costs can be greatly saved, and construction is not affected by the rainy season.

[0053] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0054] Please see Figures 1-11 In this embodiment of the invention, an airbag-type assembled shallow circular silo lifting device includes an airbag 1 and a force-bearing cloth 2 covering the airbag 1.

[0055] The airbag 1 is connected to an inflation mechanism and is cylindrical after inflation. The stress-bearing cloth 2 is provided with annular steel wire 201 and stress-bearing steel wire 202. The end of the stress-bearing steel wire 202 is provided with bolt sleeve 203. The bolt sleeve 203 is adapted to the bolt 4 provided on the warehouse wall plate 3. The outer periphery of the airbag 1 is provided with a limiting mechanism.

[0056] The limiting mechanism includes a ring beam 5, which includes four arc-shaped I-beams. Two adjacent arc-shaped I-beams are fixedly connected to each other by ring beam bolts 6 and washers 8. The ring beam 5 is provided with a first slot 501 and a first bolt hole 502. The first slot 501 is adapted to a plug-in component 9, which can be inserted into the first slot 501 and the niche 301 provided on the inner side of the warehouse wall panel 3.

[0057] The ring beam 5 cooperates with multiple sets of support mechanisms, which are equidistantly distributed along the circumference of the ring beam 5. Each support mechanism includes a support column 7, which has a support rib 704 inside and a second bolt hole 702 for connecting to the ground at its lower part. The lower part of the ring beam 5 can be connected to the ring beam support 701 provided on the support column 7 through the ring beam bolt 6. The ring beam support 701 can slide along the support column 7 through the second latch 703 provided on the support column 7.

[0058] The inflation mechanism is a high-pressure air pump.

[0059] As an example, in this embodiment, the airbag 1 (made of polyvinylidene fluoride) has a diameter of 20m and a height of 25m after inflation. The diameter of the stress-bearing cloth is 22m. Corresponding to the airbag 1, the prefabricated shallow circular silo body in this embodiment has a diameter of 25m and a height of 24m. It consists of 10 layers of prefabricated silo wall panels 3, each layer containing 16 shallow circular silo wall panels 3. Each silo wall panel 3 is 2.4m high and about 4.7m long. The fixing column is 3m high, 0.35m wide, and 0.6m long.

[0060] During construction, bolt holes are drilled in the ground beforehand, and then the ring beam support 701 is clamped on the second clamp 703. After that, the support column 7 is erected and fixed to the ground through the second bolt hole 702 and the bolt 4.

[0061] After all the support columns 7 are fixed, assemble the ring beams 5, place the four ring beams 5 on the ring beam support 701, and fix them with ring beam bolts 6. The insert 9 can be embedded in the first slot 501, and the first bolt hole 502 is used to fix the ring beams 5 and the ring beam support 701 with bolts.

[0062] After the limiting mechanism is installed, place the airbag 1 in the center of the mechanism, cover it with the stress-bearing cloth 2, and begin assembling the bin wall panel 3.

[0063] Place the prefabricated shallow circular silo wall panel 3 around the limiting mechanism, put the bolt 4 into the upper inner wall niche 301 of the silo wall panel 3, put the bolt sleeve 203 on the stress cloth 2 into the upper side of the bolt 4, and then construct the silo top.

[0064] After the silo roof construction is completed, the first layer of silo wall panel 3 is lifted. The bolt sleeve 203 is checked, and the insert 9 is embedded into the lower niche 301 of the silo wall panel 3. The airbag 1 is inflated using a high-pressure air pump. After the airbag 1 is inflated, it lifts the upper stress cloth 2, and the tension is transmitted through its stress wire 202 to the bolt 4 connected to the silo wall panel 3, which drives the silo wall panel 3 to rise. The annular wire 201 is used to keep the stress wire 202 evenly distributed. In the lower limiting mechanism, the height of the ring beam 5 is adjusted to be parallel to the height of the lower niche 301 of the silo wall. The insert 9 is embedded into the second bayonet 703 and the niche 301 of the silo wall panel. The ring beam support 701 connected by the ring beam 5 fixes the support column 7 and connects to the ground. When the silo wall panel 3 rises, the ring beam 5 moves along with it. The restriction of the fixed column 7 makes the silo wall panel 3 only move in the vertical direction.

[0065] After the first layer of warehouse wall panel 3 is raised to a height of 2.5m, the second layer of warehouse wall panel 3 is placed under it for assembly. Prestressed steel bars and bolts are used to connect them into a whole. After the assembly is completed, the first layer of warehouse wall panel 3 is lowered and the two layers of warehouse wall panels are connected by bolts 4. The plug-in component 9 of the first layer is taken out, and the ring beam 5 is slid down to the height of the niche 301 on the lower side of the second layer of warehouse wall. The plug-in component 9 is inserted into the first slot 501 and the niche 301 on the lower part of the second layer of warehouse wall panel to restrict the movement direction of the second layer of warehouse wall panel 3 when it is raised. The airbag 1 is inflated with a high-pressure air pump to raise the second layer of warehouse wall panel 3.

[0066] This process is repeated continuously, involving lifting, assembling the prestressed tendons and bolts of the silo wall panels, removing and replacing the inserts to the next layer, and lifting again, until all the silo wall panels 3 of the 10-layer shallow circular silo are assembled.

[0067] Please see Figure 12-19 The inflation mechanism includes a base 10 and further includes:

[0068] A transverse plate 28 is movably mounted on the base 10 and connected to a threaded drive assembly mounted on the base 10. The threaded drive assembly can drive the transverse plate 28 to move along the length direction of the base 10. A pumping assembly is mounted on the transverse plate 28 and is triggered when the transverse plate 28 moves.

[0069] A pipeline switching assembly is mounted on the transverse plate 28 and connected to an elastic trigger assembly mounted on the transverse plate 28. The elastic trigger assembly is triggered at the end of the travel of the transverse plate 28 and can cause the pipeline switching assembly to move.

[0070] During implementation, the threaded drive assembly operates in the forward direction, driving the transverse plate 28 to move to one side on the base 10. During this process, the air pumping assembly is triggered, which can pump air into the airbag 1. After multiple pumping operations, the assembly process of all the bin wall panels 3 can be completed. After the bin wall panel 3 assembly process is completed, the transverse plate 28 reaches the end of the movement stroke. At this time, the elastic triggering mechanism moves, causing the pipeline switching assembly to move.

[0071] When the airbag 1 needs to be removed, the threaded drive assembly reverses its operation, causing the transverse plate 28 to move toward the other side on the base 10. During this process, the pipeline switching assembly moves, and the air pump assembly is triggered to extract the gas inside the airbag 1.

[0072] The threaded drive assembly includes a lead screw 24 rotatably mounted on the base 10, a guide rod 25 fixed on the base 10, and a threaded sleeve 26 and a guide sleeve 27 respectively sleeved on the lead screw 24 and the guide rod 25.

[0073] The base 10 is also equipped with a drive motor 29, the output end of which is connected to the lead screw 24. The transverse plate 28 is fixedly connected to the threaded sleeve 26 and the guide sleeve 27. The threaded sleeve 26 is threadedly connected to the lead screw 24, and the guide sleeve 27 is slidably connected to the guide rod 25.

[0074] When the drive motor 29 is working, it can drive the lead screw 24 to rotate. Then, the guide rod 25 and the guide sleeve 27 act as guides, which will cause the threaded sleeve 26 to engage with the lead screw 24, thereby enabling the transverse plate 28 to drive the air pump assembly to move along the length direction of the base 10.

[0075] Furthermore, the drive motor 29 is selected as a servo motor with bidirectional drive at the output end. This application does not make specific limitations on its specific model, and it can be selected according to actual needs.

[0076] The air pump assembly includes a cylinder 15 fixedly installed on the transverse plate 28, a piston disc 16 slidably sealed inside the cylinder 15, and a crossbar 18 fixedly connected to the piston disc 16 via a column 17. The crossbar 18 cooperates with a circumferential rotating structure installed on the outer wall of the cylinder 15.

[0077] The circumferential rotating structure includes a disc 19 rotatably mounted on the cylinder 15 and a column 20 fixed at the eccentric position of the disc 19. The crossbar 18 is provided with a through groove adapted to the column 20. The column 20 passes through the through groove 20 and is slidably connected to the crossbar 18.

[0078] A gear 21 is rotatably mounted on the cylinder 15. The gear 21 meshes with a rack plate 22 fixedly mounted on the base 10, and a transmission belt 23 connects the rotation shafts of the gear 21 and the disc 19.

[0079] When the transverse plate 28 moves along the length of the base 10, the gear 21 will rotate because it meshes with the rack plate 22. The rotation axis of the gear 21 drives the disc 19 to rotate through the transmission belt 23. The column 20 makes a circular motion and slides with the crossbar 18 through the through groove. The crossbar 18 drives the piston disc 16 to reciprocate in the cylinder 15 through the column 17, so that the piston disc 16 can pump air into the airbag 1 or evacuate the airbag 1.

[0080] The pipeline switching assembly includes two first pipe fittings 38 connected to the cylinder 15 and two second pipe fittings 39 fixed on the cylinder 15. The two first pipe fittings 38 and the two second pipe fittings 39 are arranged opposite to each other. A first one-way valve 11, a third one-way valve 13, a second one-way valve 12, and a fourth one-way valve 14 are respectively installed on the two first pipe fittings 38.

[0081] The outer wall of the cylinder 15 is also fixed with a first guide plate 1501 and a second guide plate 1502. The elastic triggering component is installed on the first guide plate 1501. The second guide plate 1502 is slidably provided with a horizontal plate 33 connected to the elastic triggering component. The horizontal plate 33 is provided with two through holes 3301. The horizontal plate 33 is located between the first pipe 38 and the second pipe 39 and is slidably connected to the first pipe 38 and the second pipe 39 in a sealed manner. The second pipe 39, which is corresponding to the first one-way valve 11 and the third one-way valve 13, is connected to the airbag 1.

[0082] The elastic triggering component includes an assembly cylinder 30 slidably disposed on the first guide plate 1501 and a telescopic rod 31 slidably fitted with the assembly cylinder 30. The telescopic rod 31 is fixed to a ring 32 slidably disposed inside the assembly cylinder 30, and a first columnar spring 34 and a second columnar spring 35 are fitted around the outer periphery of the telescopic rod 31. The first ends of the first columnar spring 34 and the second columnar spring 35 are connected to the ring 32, and the tail ends abut against the inner wall of the assembly cylinder 30.

[0083] One end of the telescopic rod 31 is connected to the horizontal plate 33 via a connecting rod 36. The two ends of the connecting rod 36 are respectively hinged to the telescopic rod 31 and the horizontal plate 33. A limiting plate 37 is also fixed on the base 10. The limiting plate 37 is provided with a rectangular groove and an inclined groove 3705. The other end of the telescopic rod 31 extends into the rectangular groove and is slidably connected to the limiting plate 37. A protruding post 3001 is fixed on the assembly cylinder 30. The protruding post 3001 extends into the inclined groove 3705 and is slidably connected to the limiting plate 37.

[0084] In detail, the rectangular groove includes a first groove segment 3701, a second groove segment 3702, a third groove segment 3703, and a fourth groove segment 3704 connected together;

[0085] When the two through holes 3301 correspond to the first one-way valve 11 and the second one-way valve 12 respectively, when the piston disc 16 moves upward, the second one-way valve 12 is open and the first one-way valve 11 is closed, so outside air can be drawn into the cylinder 15. When the piston disc 16 moves downward, the second one-way valve 12 is closed and the first one-way valve 11 is open, so the gas in the cylinder 15 can be pumped into the airbag 1 to realize the inflation function of the airbag 1.

[0086] When the transverse plate 28 moves, the protruding post 3001 moves along the inclined groove 3705, thereby causing the assembly cylinder 30 to slide upward on the first guide plate 1501. The end of the telescopic rod 31 away from the connecting rod 36 slides along the first groove 3701, and the first column spring 34 is compressed. After the transverse plate 28 moves to the end of its stroke, the entire inflation process of the airbag 1 ends, and the end of the telescopic rod 31 away from the connecting rod 36 reaches the first groove 3701 and the second groove 3705. At the intersection of 2, the first cylindrical spring 34 rebounds, and the end of the telescopic rod 31 away from the connecting rod 36 moves along the second groove 3702 to the intersection of the second groove 3702 and the third groove 3703. Correspondingly, the telescopic rod 31 slides upward on the assembly cylinder 30 and pulls the cross plate 33 to slide on the second guide plate 1502 through the connecting rod 36, so that the two through holes 3301 correspond to the third one-way valve 13 and the fourth one-way valve 13 respectively.

[0087] Subsequently, during the reverse movement and reset of the transverse plate 28, when the piston disc 16 moves upward, the third one-way valve 13 is open and the fourth one-way valve 14 is closed. As a result, the gas in the airbag 1 is drawn into the cylinder 15. When the piston disc 16 moves downward, the third one-way valve 13 is closed and the fourth one-way valve 14 is open, thereby the gas in the cylinder 15 is discharged, realizing the automatic venting function of the airbag 1.

[0088] As an embodiment of the present invention, a method for lifting an airbag-type prefabricated shallow circular silo is also proposed, which uses the aforementioned lifting device and includes the following steps:

[0089] Step 1: Drill bolt holes in the ground, then clip the ring beam support 701 onto the second latch 703, then erect the support column 7, and fix the support column 7 to the ground through the second bolt hole 702 and bolt 4.

[0090] Step 2: Place the four ring beams 5 on the ring beam support 701 and fix them with ring beam bolts 6. The insert 9 can be embedded in the first slot 501 and the first bolt hole 502 is used to fix the ring beams 5 and the ring beam support 701 with bolts.

[0091] Step 3: Place airbag 1 and cover it with stress-bearing cloth 2;

[0092] Step 4: Place a ring of silo wall panels 3, put the bolts 4 into the upper inner wall niches 301 of the silo wall panels 3, and put the bolt sleeves 203 on the stress-bearing cloth 2 onto the upper side of the bolts 4, and then construct the silo top.

[0093] Step 5: Check the bolt sleeve 203 and insert the plug 9 into the lower niche 301 of the bin wall panel 3. Use a high-pressure air pump to inflate the airbag 1. After the airbag 1 is inflated, it lifts the upper stress cloth 2 and transmits the tension through its stress wire 202 to the bolt 4 connected to the bin wall panel 3, causing the bin wall panel 3 to rise.

[0094] Step 6: Remove the first layer insert 9, slide the ring beam 5 down to the height of the second layer warehouse wall lower niche 301, insert the insert 9 into the first slot 501 and the second layer warehouse wall panel lower niche 301, restrict the movement direction of the second layer warehouse wall panel 3 when it is lifted, use a high pressure air pump to inflate the airbag 1, and lift the second layer warehouse wall panel 3.

[0095] Step 7: Repeat the jacking, assembly of prestressed tendons and bolts for the silo wall panels, removal of inserts and replacement of the next layer, and jacking operation until all 10 layers of shallow circular silo wall panels 3 are assembled.

[0096] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0097] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
