Description

Technical Field

[0001] The invention relates to the field of transport storage racks, and in particular to an assembled storage rack that is convenient for transportation. Background Art

[0002] Warehousing logistics is the use of self-built or leased warehouses and sites to store, keep, load and unload, and distribute goods. The traditional definition of warehousing is given from the perspective of material storage. Modern "warehousing" is not a "warehouse" or "warehouse management" in the traditional sense, but warehousing in the context of economic globalization and supply chain integration, and warehousing in the modern logistics system.

[0003] Storage shelves are important equipment in warehousing logistics. However, at present, the size, volume and capacity of existing storage shelves are fixed. When large shelves are used to store small items, the utilization rate will be reduced. At the same time, the fixed volume will increase the labor force required for staff to carry or move the shelves and keep them idle, making them less suitable. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an assembled storage shelf that is convenient for transportation, thereby overcoming the deficiencies of the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an assembled storage shelf that is convenient for transportation, comprising a bottom plate, a plurality of placement plates are uniformly and equidistantly arranged at the upper and lower ends of the bottom plate, the plurality of placement plates are connected to each other by steel wire ropes, the upper end of the bottom plate is symmetrically rotatably connected to two bidirectional screw rods, and the two bidirectional screw rods are connected by a pulley transmission, a rotating assembly for driving the bidirectional screw rod to rotate is installed on the bottom plate, two movable blocks are symmetrically threaded on the rod wall of the bidirectional screw rod, the upper end of the movable block is hinged with a driving rod, and the other end of the driving rod is hinged Connected to the corresponding placement plate, the upper end of the placement plate is symmetrically rotatably connected to two rotating shafts, two support frames are symmetrically sleeved on the axis wall of the rotating shaft, and the corresponding placement plate is in contact with the support frame, two groups of torsion springs are symmetrically installed on the upper end of the placement plate, the other end of the torsion spring is connected to the corresponding support frame, and the torsion spring is sleeved on the corresponding rotating shaft, the upper end of the placement plate is symmetrically slidably connected to two groups of movable plates, the upper end of the movable plate is hinged with a connecting rod, the other end of the connecting rod is hinged to the corresponding supporting frame, and a limit assembly for limiting the movement of the movable plate is installed on the placement plate.

[0006] By adopting the above technical solution, when it is necessary to store multiple goods, the two-way screw rod is rotated by rotating the assembly, and the two two-way screw rods will rotate simultaneously through the pulley. The rotation of the two-way screw rod will exert a force on the movable block, and the movable block will exert a force on the highest placement plate through the driving rod under the force, and the highest placement plate will move upward. When the placement plate moves to the specified position, the steel wire rope connecting the two placement plates will be straightened, and when the highest placement plate continues to move upward, the steel wire rope will drive the lower placement plate to move upward. The operation in sequence will separate several placement plates for storing goods, and when the upper placement plate is moving, the torsion spring will exert a force on the rotating shaft, and the rotating shaft will rotate under the force, and the rotation of the rotating shaft will drive the support frame to rotate, and when the steel wire rope is straightened, the top of the support frame is vertical to the upper placement plate, and the support frame will The support plate is supported by the plate, and the rotation of the support frame will also apply a force to the moving plate through the connecting rod. The moving plate will move in the horizontal direction under the force, and then the moving plate will be limited by the limit assembly, thereby limiting the support frame and preventing the support frame from rotating. When a small number of small objects need to be stored, the limit assembly is removed from the moving plate, and the support frame is tilted by the rotating shaft, and then the highest placement plate is moved downward by the two-way screw rod and the driving rod. When the highest placement plate moves downward, it will apply a force to the support frame to make the support frame rotate downward with the rotating shaft as the center. The rotation of the rotating shaft will drive the torsion spring to rotate, so that the torsion spring is deformed, and the operation is performed in sequence to make several placement plates stacked. Through the above structure, multiple placement plates can be unfolded, stored and stacked, and can be adjusted according to the needs of goods. The operation is simple and convenient, reducing manual labor, thereby improving the applicability of the device.

[0007] As a preferred technical solution of the present invention, the rotating assembly includes a motor fixedly mounted on the upper end of the base plate, and the output end of the motor is connected to the corresponding bidirectional screw through a coupling.

When the limiting rod is inserted into the clamping hole, the limiting rod will limit the movable plate to prevent the movable plate from moving.

[0011] As a preferred technical solution of the present invention, two groups of slide grooves are symmetrically opened on the upper end of the placement plate, and sliders are slidably connected in the slide grooves, and the upper ends of the sliders are connected to the corresponding movable plates.

[0012] By adopting the above technical solution, the movable plate is limited and the stability of the movement of the movable plate is improved.

[0013] As a preferred technical solution of the present invention, a sliding rod is fixedly connected to the inner groove wall of the sliding groove, the sliding rod passes through the sliding block, and the sliding block is slidably connected to the sliding rod.

[0014] By adopting the above technical solution, the sliding block is prevented from being separated from the sliding groove.

[0015] As a preferred technical solution of the present invention, a rolling groove is opened at one end of the sliding block, a rolling ball is arranged in the rolling groove, the ball passes through the notch of the rolling groove, and the ball is rollingly connected to the bottom of the sliding groove.

[0021] As a preferred technical solution of the present invention, two sets of moving wheels are symmetrically installed at the lower end of the base plate.

[0022] By adopting the above technical solution, it is convenient to move the bottom plate.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) The present invention sets up structures such as a bottom plate, a placement plate, a wire rope, a bidirectional screw rod, a movable block, a driving rod, a motor, a limit sleeve and a fixed rod. The two bidirectional screw rods are rotated by the motor and the pulley. The rotation of the bidirectional screw rods will cause the movable block to move through the thread action. The movement of the movable block will drive the highest placement plate to move upward through the driving rod. When the placement plate moves to a specified position, the wire rope connecting the two placement plates will be straightened. When the highest placement plate continues to move upward, the wire rope will drive the placement plate below to move upward. The operation in sequence will separate several placement plates for storing goods. When the placement plates need to be stacked, the above operation can be performed in reverse. Multiple placement plates can be unfolded, stored and stacked through the upper structure, and can be adjusted according to the needs of the goods. The operation is simple and convenient, reducing manual labor, thereby improving the applicability of the device.

[0025] (2) The present invention sets structures such as a rotating shaft, a support frame, a torsion spring, a movable plate, a connecting rod, a motor, a limit tube, a spring and a limit rod. When the upper placement plate is moving, the torsion spring will drive the support frame to rotate through the rotating shaft, so that the support frame supports the placement plate. The rotation of the support frame will also apply a force to the movable plate through the connecting rod. The movable plate will move horizontally under the force. When the clamping hole on the movable plate moves to the position of the limit rod, the limit rod is inserted into the clamping hole to limit the movable plate and prevent the movable plate from moving. Therefore, the support frame is limited to prevent the support frame from rotating. The upper structure can support two adjacent placement plates to prevent the placement plate from moving downward quickly when the wire rope breaks, thereby improving the safety of the device.

The torsion spring 9 is in a deformed state. The upper end of the placement plate 2 is symmetrically slidably connected to two sets of moving plates 10. The upper end of the placement plate 2 is symmetrically opened with two sets of slide grooves, and a slider 16 is slidably connected in the slide groove. The slider 16 The upper end is connected to the corresponding movable plate 10 to limit the movable plate 10 and improve the stability of the movement of the movable plate 10. A sliding rod 17 is fixedly connected to the inner wall of the slide groove. The sliding rod 17 passes through the slider 16, and the slider 16 is slidably connected to the sliding rod 17 to prevent the slider 16 from escaping from the slide groove. A rolling groove is provided at one end of the slider 16, and a rolling ball 18 is provided in the rolling groove. The ball 18 passes through the notch of the rolling groove and is rollingly connected to the bottom of the slide groove to reduce the friction between the slider 16 and the slide groove.

[0038] For details, see Figure 1-3 and Figure 5The upper end of the movable plate 10 is hinged with a connecting rod 11, and the other end of the connecting rod 11 is hinged on the corresponding support frame 8. A limiting assembly for limiting the movement of the movable plate 10 is installed on the placement plate 2. The limiting assembly includes two sets of limiting tubes 13 symmetrically connected to the upper end of the placement plate 2.

When the card hole on the movable plate 10 moves to the position of the limit rod 15, the spring 14 will apply a force to the limit rod 15 to make the limit rod 15 move in the limit tube 13. When the limit rod 15 is inserted into the card hole, the limit rod 15 will limit the movable plate 10 to prevent the movable plate 10 from moving.

[0039] When the upper placement plate 2 is moving, the torsion spring 9 will apply a force to the rotating shaft 7, and the rotating shaft 7 will rotate under the force, and the rotation of the rotating shaft 7 will drive the support frame 8 to rotate. When the wire rope 3 is straightened, the top of the support frame 8 is vertical to the upper placement plate 2, and the support frame 8 will support the placement plate 2. The rotation of the support frame 8 will also apply a force to the moving plate 10 through the connecting rod 11, and the moving plate 10 will move horizontally under the force. When the clamping hole on the moving plate 10 moves to the position of the limiting rod 15, the spring 14 will apply a force to the limiting rod 15 to make the limiting rod 15 move in the limiting tube 13.

When a few small objects need to be stored, the limit rod 15 is removed from the card hole, and the support frame 8 is tilted by rotating the shaft 7, and then the highest placement plate 2 is moved downward by the two-way screw rod 4 and the driving rod 6. When the highest placement plate 2 moves downward, it will exert a force on the support frame 8 to make the support frame 8 rotate downward with the rotating shaft 7 as the center. The rotation of the rotating shaft 7 will drive the torsion spring 9 to rotate, so that the torsion spring 9 is deformed, and the operation is performed in sequence to stack several placement plates 2.
