Description

Technical Field

[0001] The invention belongs to the technical field of flexible warehouse deployment and retraction, and in particular relates to a large-volume flexible warehouse deployment and retraction device. Background Art

[0002] With the rapid development of the national economy, the logistics industry has risen rapidly. The demand for the storage and transportation of large quantities of goods of various shapes and certain large-scale engineering equipment in certain areas in a short period of time is increasing. Compared with traditional fixed steel structures and house-type warehouses, large-volume flexible warehouses have the advantages of energy saving, high efficiency, strong mobility and high flexibility. In addition, large-volume flexible warehouses can also be applied to disaster relief, emergency rescue, field team investigation and exploration, field camping, field construction and other scenes for personnel residence and equipment storage.

[0003] The existing flexible warehouse is similar to the military combined tent in China Patent No. 201110135856.6. The temporary warehouse built with this kind of tent has a low internal height and can only be used for living or placing some small goods with limited height. It is difficult to meet the storage needs of high-precision and large-scale equipment with high requirements for outdoor environment. When building this kind of tent, the user needs to manually build the tent frame and then install the tarpaulin and the periphery. When disassembling, the user also needs to repeat the installation work. Therefore, the larger the temporary warehouse area, the greater the repeated workload of tent installation and disassembly, and the labor cost and time cost are doubled. In addition, the height of the temporary warehouse built with this kind of tent is limited, which limits the types of goods stored.

[0004] Chinese Patent No. 202011270405.9 discloses a large tent installation device, a large tent equipment and a large tent vehicle. Although the temporary warehouse built has a larger usable area than traditional military tents, the installation device uses a first-stage oil cylinder to extend and retract, which results in a large weight of the installation device body, limited retractable height and inability to expand and retract the tent in the horizontal direction.

[0021] The tray 1 is a horizontally arranged square plate-shaped structure, and rollers are arranged on the lower end surface of the tray 1, and the movement of the tray 1 is achieved by the rollers.

[0022] The basic column 7 is a square cylindrical structure with an open upper end. The lower end of the basic column 7 is fixedly connected to one end of the upper end surface of the tray 1. Two inclined support rods are fixedly arranged on the outer side of the basic column 7. The support rods are fixedly connected to the upper end surface of the tray 1. The verticality of the basic column 7 is ensured by the two support rods.

[0023] The secondary column 8, tertiary column 9, fourth column 10 and fifth column 11 are all vertically arranged square cylindrical structures with open upper and lower ends. The lower end of the secondary column 8 is slidably inserted into the upper opening of the basic column 7, the lower end of the tertiary column 9 is slidably inserted into the upper opening of the secondary column 8, the lower end of the fourth column 10 is slidably inserted into the upper opening of the tertiary column 9, and the lower end of the fifth column 11 is slidably inserted into the upper opening of the fourth column 10.

[0024] The vertical telescopic assembly includes a vertical telescopic oil cylinder 12 , a first pulley 13 , a second pulley 15 , a third pulley 17 , a vertical three-extension steel wire rope 14 , a vertical four-extension steel wire rope 16 , and a vertical five-extension steel wire rope 18 .

[0025] A vertical telescopic oil cylinder 12 is arranged inside the fifth-level column 11, and the piston rod of the vertical telescopic oil cylinder 12 is vertically downward, and one end of the piston rod at the lower end of the vertical telescopic oil cylinder 12 is hinged to the lower end of the inner wall of the basic column 7 through a first pin shaft. The left and right sides of the lower end of the outer side surface of the vertical telescopic oil cylinder 12 are respectively hinged to the lower ends of the left and right inner walls of the secondary column 8 through a second pin shaft. The axes of the first pin shaft and the second pin shaft are both arranged horizontally along the left and right directions.

[0026] A first pulley 13 is rotatably provided at the upper end of the vertical telescopic cylinder 12, and a vertical three-extension steel wire rope 14 is wound around the outer side of the first pulley 13. The vertical three-extension steel wire rope 14 is a U-shaped structure with an opening downward. One end of the vertical three-extension steel wire rope 14 is fixedly provided on the lower end of the inner wall of the basic column 7, and the other end of the vertical three-extension steel wire rope 14 is fixedly connected to the lower end of the inner wall of the third-level column 9 after passing around the first pulley 13.

[0027] When the piston rod of the vertical telescopic oil cylinder 12 extends outward from the retracted state, since the basic column 7 is fixed, the cylinder body of the vertical telescopic oil cylinder 12 drives the secondary column 8 to extend upward. At the same time, the cylinder body of the vertical telescopic oil cylinder 12 drives the first pulley 13 to slide upward, and the first pulley 13 drives the vertical three-extension steel wire rope 14 to move synchronously. Since the end of the vertical three-extension steel wire rope 14 connected to the basic column 7 is fixed, it drives the end of the vertical three-extension steel wire rope 14 connected to the tertiary column 9 to slide upward, thereby driving the tertiary column 9 to extend upward synchronously with the secondary column 8. The extension speed of the piston rod of the vertical telescopic oil cylinder 12 is v, and the extension speed of the secondary column 8 is the same as the extension speed of the piston rod of the vertical telescopic oil cylinder 12, both v. Under the action of the vertical three-extension steel wire rope 14, the extension speed of the tertiary column 9 is 2v.

[0028] A second pulley 15 is rotatably arranged on the inner walls on the left and right sides of the upper opening of the third column 9, and the two second pulleys 15 are respectively located on the left and right sides of the fourth column 10, and the axis of the second pulley 15 is arranged horizontally along the left and right direction. A vertical four-extension steel wire rope 16 is wound around the outer side of each second pulley 15, and the vertical four-extension steel wire rope 16 is a U-shaped structure with an opening downward, one end of the vertical four-extension steel wire rope 16 is fixedly arranged at the lower end of the inner wall of the second column 8, and the other end of the vertical four-extension steel wire rope 16 is fixedly connected to the lower end of the fourth column 10 after passing the second pulley 15.

[0029] When the tertiary column 9 is extended upward, it drives the left and right second pulleys 15 to slide upward at the same time, and the two second pulleys 15 respectively drive the left and right vertical four-extension steel wire ropes 16 to move synchronously. Since the end of the vertical four-extension steel wire rope 16 connected to the secondary column 8 slides upward at a speed of v, the second pulley 15 is extended upward at a speed of 2v along with the tertiary column 9, and there is a speed difference of v between the end of the vertical four-extension steel wire rope 16 connected to the secondary column 8 and the second pulley 15. The end of the vertical four-extension steel wire rope 16 connected to the secondary column 8 and the tertiary column 9 both drive the fourth column 10 to extend upward at a speed of v first, and at the same time, the speed difference v becomes 2v under the action of the vertical four-extension steel wire rope 16, and the speed drives the fourth column 10 to slide upward relative to the third column 9, and the total speed of the fourth column 10 is 3v upward.

[0030] A third pulley 17 is rotatably arranged on the front and rear inner walls of the upper opening of the fourth-level column 10, and the two third pulleys 17 are respectively located on the front and rear sides of the fifth-level column 11, and the axis of the third pulley 17 is arranged horizontally along the front-to-back direction. A vertical five-stretch steel wire rope 18 is wound around the outer side of each third pulley 17, and the vertical five-stretch steel wire rope 18 is a U-shaped structure with an opening downward, one end of the vertical five-stretch steel wire rope 18 is fixedly connected to the lower end of the inner wall of the third-level column 9, and the other end of the vertical five-stretch steel wire rope 18 is fixedly connected to the lower end of the fifth-level column 11 after passing the third pulley 17.

[0031] When the fourth-level column 10 extends upward, it drives the front and rear two third pulleys 17 to slide upward at the same time, and the two third pulleys 17 respectively drive the left and right vertical five-extension steel wire ropes 18 to move synchronously. Since the end of the vertical five-extension steel wire rope 18 connected to the third-level column 9 slides upward at a speed of 2v, the third pulley 17 extends upward at a speed of 3v along with the fourth-level column 10. There is a speed difference of v between the end of the vertical five-extension steel wire rope 18 connected to the third-level column 9 and the third pulley 17. The end of the vertical five-extension steel wire rope 18 connected to the third-level column 9 and the fourth-level column 10 both drive the fifth-level column 11 to extend upward at a speed of 2v. At the same time, the speed difference v becomes 2v under the action of the vertical five-extension steel wire rope 18, driving the fifth-level column 11 to slide upward relative to the fourth-level column 10, and the total speed of the five-level column 11 is 4v upward.

[0032] When the piston rod of the vertical telescopic oil cylinder 12 extends outward at a speed of v, the extension speed of the secondary column 8 is v, the extension speed of the tertiary column 9 is 2v, the extension speed of the quaternary column 10 is 3v, and the extension speed of the quintuple column 11 is 4v. When the piston rod of the vertical telescopic oil cylinder 12 is fully extended, the secondary column 8, the tertiary column 9, the quaternary column 10, and the quintuple column 11 are also fully extended. At this time, the telescopic column 2 reaches the maximum length, and the two horizontal telescopic arms 3 also reach the maximum height.

[0033] When the piston rod of the vertical telescopic oil cylinder 12 is retracted inward from the extended state, the cylinder body of the vertical telescopic oil cylinder 12 drives the secondary column 8 to be retracted inward at a speed of v. Since the telescopic column 2 is vertically arranged, the tertiary column 9, the fourth column 10, and the fifth column 11 are gradually retracted under the action of gravity. The tertiary column 9 is retracted inward at a speed of 2v under the action of the vertical three-extension steel wire rope 14, the fourth column 10 is retracted inward at a speed of 3v under the action of the vertical four-extension steel wire rope 16, and the fifth column 11 is retracted inward at a speed of 4v, until the vertical telescopic oil cylinder 12 is completely retracted, at which time the telescopic column 2 reaches the minimum length and the two horizontal telescopic arms 3 also reach the minimum height.

[0034] The basic arm 21, the second-section arm 22, and the third-section arm 23 are all horizontally arranged square cylindrical structures with openings at both ends. The lower end of the outer side surface of the basic arm 21 of the two horizontal telescopic arms 3 is fixedly provided with the same upper flange 20, the tail end of the second-section arm 22 is slidably inserted into the inside of the head end opening of the basic arm 21, and the tail end of the third-section arm 23 is slidably inserted into the inside of the head end opening of the second-section arm 22.

[0035] A lower flange 19 is fixedly provided at the upper end of the five-level column 11 . The lower flange 19 on the five-level column 11 is fixedly connected to the upper flange 20 by fixing bolts and fixing nuts, thereby fixing the two horizontal telescopic arms 3 to the upper end of the five-level column 11 .

[0037] The horizontal telescopic oil cylinder 24 is arranged inside the three-section boom 23, and the axis of the horizontal telescopic oil cylinder 24 is kept coincident with the length direction of the three-section boom 23. One end of the piston rod of the horizontal telescopic oil cylinder 24 is hinged to the inner wall of the tail end of the basic arm 21 through the third pin shaft, and one end of the cylinder body of the horizontal telescopic oil cylinder 24 close to the piston rod is hinged to the inner wall of the tail end of the second section boom 22. The piston rod of the horizontal telescopic oil cylinder 24 is extended to drive the second section boom 22 to extend outward.

[0038] A fourth pulley 25 is rotatably provided at one end of the bottom of the horizontal telescopic cylinder 24, and a U-shaped horizontal three-extension steel wire rope 26 is wound around the outside of the fourth pulley 25. One end of the horizontal three-extension steel wire rope 26 is fixedly connected to the inner wall of the tail end of the basic arm 21, and the other end of the horizontal three-extension steel wire rope 26 is fixedly connected to the inner wall of the tail end of the three-section arm 23 after passing around the fourth pulley 25.

[0039] When the piston rod of the horizontal telescopic cylinder 24 extends outward from the retracted state, the cylinder body of the horizontal telescopic cylinder 24 drives the two-section arm 22 and the fourth pulley 25 to extend outward synchronously, and the fourth pulley 25 drives the horizontal three-section extension wire rope 26 to move synchronously. Since the end of the horizontal three-section extension wire rope 26 connected to the basic arm 21 is fixed, the end of the horizontal three-section extension wire rope 26 connected to the three-section arm 23 is driven to extend outward, thereby driving the three-section arm 23 to extend outward along with the two-section arm 22.

[0040] A fifth pulley 27 is rotatably provided at the tail end of the two-section arm 22, and a U-shaped horizontal three-retractable steel wire rope 28 is wound around the outside of the fifth pulley 27. One end of the horizontal three-retractable steel wire rope 28 is fixedly connected to the inner wall of the head end of the basic arm 21, and the other end of the horizontal three-retractable steel wire rope 28 is fixedly connected to the tail end of the three-section arm 23 after passing around the fifth pulley 27.

[0041] When the piston rod of the horizontal telescopic cylinder 24 is retracted inward from the extended state, the cylinder body of the horizontal telescopic cylinder 24 drives the two-section arm 22 and the fifth pulley 27 to be retracted inward synchronously, and the fifth pulley 27 drives the horizontal three-retractable steel wire rope 28 to move synchronously. Since the end of the horizontal three-retractable steel wire rope 28 connected to the basic arm 21 is fixed, it drives the end of the horizontal three-retractable steel wire rope 28 connected to the three-section arm 23 to be retracted inward, thereby driving the three-section arm 23 to be retracted inward along with the two-section arm 22.

[0042] A hydraulic system 5 and an electrical system 6 are also provided on the pallet 1. The hydraulic system 5 is connected to the vertical telescopic cylinder 12 and the horizontal telescopic cylinder 24, and the vertical telescopic cylinder 12 and the horizontal telescopic cylinder 24 are driven to extend and retract by the hydraulic system 5. The electrical system 6 includes an electric control box (including a controller), a sensor, a cable and an electrical connector.

[0043] The two transfer mechanisms 4 are fixedly connected to the two docking points of the flexible warehouse respectively.

[0044] The working principle of the present invention is: When in the folded state, the flexible warehouse, the telescopic column 2 and the horizontal telescopic arm 3 are folded together and placed on the pallet 1, and the pallet 1 is placed on the trailer as a whole, and the trailer is used to realize the overall movement of the flexible warehouse and the unfolding and folding device.

[0045] When the flexible warehouse is unfolded, the flexible warehouse and the stowage device are first placed on a large open space by a trailer, the basic frame of the flexible warehouse is manually unfolded, and then the stowage device is remotely controlled to extend horizontally and then vertically raised. After the flexible warehouse is supported, the stowage device fixed to the pallet 1 is towed out by a trailer to make room for storing goods in the warehouse.

[0046] When folding, the stowage device fixed on the pallet 1 is pulled into the flexible warehouse by a trailer, and the remote control controls the horizontal telescopic arm 3 and the telescopic column 2 of the stowage device to unfold. The left and right positions of the horizontal telescopic arm 3 are controlled to make the two transfer mechanisms 4 on the stowage device connect with the two docking points of the flexible warehouse. Then, the flexible warehouse is lifted off the ground and the force is unloaded. The horizontal telescopic arm 3 and the telescopic column 2 of the stowage device are retracted by remote control again. Finally, the flexible warehouse is retracted to the wheeled pallet 1 of the stowage device, and the flexible warehouse is transferred by a trailer, thereby completing the entire flexible warehouse construction and folding process.
