Description

Technical Field

[0001] The utility model relates to the technical field of layer-changing elevators, in particular to a shelf-attached layer-changing elevator. Background Art

[0002] The level-changing elevator consists of a support frame, a lifting device, and a loading platform. The support frame includes support columns, and a lifting device is mounted on the support frame. The lifting device is used to adjust the height of the loading platform. The loading platform rises and falls along the support columns and is used to carry shuttles. When the lifting device transports the loading platform to the corresponding cargo level of the shelf, the shuttle on the loading platform enters the shelf's shuttle track and travels to transport the goods.

[0003] Since the layer-changing elevator is independent of the shelf as a whole and the height of the layer-changing elevator is relatively high, the stability of the layer-changing elevator is relatively weak, which easily increases the deflection of the supporting columns in the layer-changing elevator. The greater the deflection, the easier it is to deform. The greater the deformation of the supporting columns, the more it will reduce the accuracy of the shuttle car when transitioning between the loading platform and the shelf, thereby reducing the accuracy and safety of the operation.

[0004] Therefore, how to improve the stability of the layer-changing elevator is a technical problem that needs to be solved at present. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention proposes a shelf-attached layer-changing elevator. The present invention can improve the stability of the layer-changing elevator.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A shelf-attached layer-changing elevator includes supporting columns, a lifting device and a vehicle loading platform. The vehicle loading platform is raised and lowered along the supporting columns by the lifting device. Multi-layer shuttle tracks are arranged in the lanes between the shelves, and the supporting columns are attached to the multi-layer shuttle tracks.

[0008] Furthermore, two groups of support columns are provided, and the two groups of support columns are respectively attached to the multi-layer shuttle tracks on both sides of the tunnel.

[0009] Furthermore, the vehicle loading platform includes a fixed part and a sliding part, a docking track is provided on the upper part of the sliding part, and the sliding part is slidably arranged on the fixed part. The sliding part is used to drive the docking track to dock with one layer of the shuttle track on the lane through a sliding drive structure.

[0010] Furthermore, the shuttle track is provided with a first zigzag edge on a side facing the docking track, and the docking track is provided with a second zigzag edge on a side facing the shuttle track, and the second zigzag edge is used to match and abut with the first zigzag edge.

[0011] Furthermore, a blocking device is included, which prevents the shuttle from passing when the docking track is not docked with the shuttle track. The blocking device is arranged on the shuttle track and / or the docking track.

[0012] Furthermore, the blocking device includes a mounting seat, a docking block, and a blocking block, wherein the docking block and the blocking block are hingedly arranged on the mounting seat, and the docking block is perpendicular to the rotation direction of the blocking block; when in a state without external force, the blocking block is in contact with the shuttle track; when the shuttle track is docked with the docking track, the docking track pushes the docking block to rotate through the pushing block, and the other end of the docking block presses down the blocking block, so that the blocking block is detached from the shuttle track; the docking block and / or the blocking block are reset by a reset spring.

[0013] Furthermore, the docking track is provided with a limiting structure at one end away from the shuttle track, and the limiting structure is used to limit the shuttle from continuing to move in a direction away from the shuttle track.

[0014] Furthermore, the fixing portion is provided with a detection device at one end away from the shelf, and the detection device is used to detect whether the shuttle vehicle is parked in place.

[0015] Furthermore, the lifting device includes a lifting drive structure, a lifting belt and a guide structure. The vehicle carrier is slidably arranged on the support column through the guide structure. The lifting drive structure includes a drive motor and a synchronous shaft. The lifting belt is provided with at least two groups. The synchronous shaft is provided with synchronous pulleys corresponding to the lifting belt. The lifting drive structure drives the vehicle carrier to rise and fall through the lifting belt.

[0016] Furthermore, the lifting device also includes an anti-deflection clamping wheel group, which clamps the two sides of the lifting belt to correct the deviation.

[0017] The utility model has the beneficial effects:

[0018] 1. In the present invention, since the support columns are attached to the multi-layer shuttle rails, the strength of the support columns is improved, which reduces the risk of deformation of the support columns and is conducive to improving the stability of the shelf-attached layer-changing elevator of the present invention.

[0019] 2. After the docking track and the shuttle track are docked, the abutment of the first curved edge and the second curved edge can align the docking track and the shuttle track in multiple directions, which is beneficial to improve the docking accuracy and stability and facilitate the smooth transition of the shuttle.

[0020] 3. When the docking track and the shuttle track are not fully docked, the blocking device prevents the shuttle from moving between them. Only after the docking track and the shuttle track are fully docked will the blocking device allow the shuttle to move between them. This improves the operational reliability of the entire floor-changing elevator.

[0021] 4. When the shuttle car moves onto the docking track, the limit structure can limit the shuttle car from continuing to move away from the docking track on the docking track, preventing the shuttle car from falling from the docking track, thereby improving safety.

[0023] 6. The anti-deviation clamp wheel group can prevent the lifting belt from moving, improve the stability and reliability of the lifting belt wrapped around the synchronous pulley, and then help improve the operating reliability of the entire layer-changing elevator.

[0034] Example 1:

[0035] A shelf-attached layer-changing elevator comprises a support frame, an elevator device and a vehicle loading platform.

[0036] Multiple layers of shuttle tracks 14 are provided in the lanes between the shelves. The shuttle tracks 14 also serve as the crossbeams of the shelves. Each layer of shuttle tracks 14 is used for shuttles (not shown in the figure) to travel on them.

[0037] See also Figure 1 The support frame includes a base 11, a top beam 12, and two sets of support columns 13. The bottoms of the two sets of support columns 13 are fixedly mounted on the base 11, and the top beam 12 is fixedly mounted on the tops of the two sets of support columns 13. The two sets of support columns 13 are respectively attached to the multi-layer shuttle tracks 14 on both sides of the roadway, and the support columns 13 are fixedly connected to the shuttle tracks 14.

[0038] See also Figure 1 and Figure 3 The lifting device includes a lifting drive structure, a lifting belt 23 and a guide structure (not shown in the figure). The guide structure can adopt a guide wheel group, and the vehicle carrier is slidably set on the support column 13 through the guide structure. There are at least two groups of lifting belts 23. In this embodiment, there are two groups of lifting belts 23. The lifting drive structure is installed on the base 11. The lifting drive structure includes a drive motor and a synchronous shaft (not shown in the figure). The drive motor can adopt a servo motor 21. The output end of the servo motor 21 is connected to the synchronous shaft. A synchronous pulley (not shown in the figure) corresponding to the lifting belt 23 is installed on the synchronous shaft. The synchronous pulley is transmitted to the driven wheel group 22 through the lifting belt 23. The driven wheel group 22 is installed on the top beam 12.

[0039] See also Figure 1 The vehicle loading platform is connected to the lifting belt 23, and the vehicle loading platform is used to carry the shuttle vehicle.

[0040] When the servo motor 21 drives the synchronous pulley to rotate forward, the lifting belt 23 carries the vehicle loading platform up; when the servo motor 21 drives the synchronous pulley to rotate reversely, the lifting belt 23 carries the vehicle loading platform down; the shuttle vehicle on the vehicle loading platform rises and falls with the vehicle loading platform.

[0041] In the shelf-attached layer-changing elevator of this embodiment, because the support column 13 is attached to the multi-layer shuttle track 14, the strength of the support column 13 is improved, which reduces the risk of deformation of the support column 13 and is conducive to improving the stability of the shelf-attached layer-changing elevator of this embodiment.

[0042] Example 2:

[0043] This embodiment 2 provides a specific structure of the vehicle loading platform in embodiment 1:

[0044] See also Figure 2 The vehicle loading platform includes a fixed part 31, a sliding part 32, a docking rail 33, and a sliding drive structure. The fixed part 31 is fixedly connected to the lifting belt 23. When the servo motor 21 drives the synchronous pulley to rotate, the lifting belt 23 carries the fixed part 31 up and down. The guide wheel group is installed on the side of the fixed part 31. When the fixed part 31 is raised or lowered, the guide wheel group moves up and down along the support column 13. A sliding part 32 is provided on the upper part of the fixed part 31. A docking rail 33 is fixedly installed on the upper part of the sliding part 32. The docking rail 33 is used to dock with the shuttle track 14. A sliding drive structure is installed on the fixed part 31. The sliding drive structure is used to drive the sliding part 32 to move laterally. In this embodiment, the sliding drive structure adopts a telescopic rod 34. The telescopic rod 34 can adopt an oil cylinder, an air cylinder, or an electric push rod. One end of the telescopic rod 34 is fixedly connected to the fixed part 31, and the other end of the telescopic rod 34 is fixedly connected to the sliding part 32.

[0045] When the telescopic rod 34 is extended, the telescopic rod 34 drives the sliding part 32 to approach the shelf, so that the docking track 33 gradually docks with the shuttle track 14; when the docking track 33 and the shuttle track 14 are docked, the shuttle can move on the docking track 33 and the shuttle track 14; when the telescopic rod 34 is shortened, the telescopic rod 34 drives the sliding part 32 away from the shelf, so that the docking track 33 leaves the shuttle track 14.

[0046] For further information, see Figure 2 A slide rail 311 is mounted on the fixed portion 31, and a slide seat (not shown) is mounted on the sliding portion 32. The slide seat and the slide rail 311 slide in a transverse sliding manner. When the telescopic rod 34 drives the sliding portion 32 toward or away from the shelf, the sliding portion 32 drives the slide seat to slide along the slide rail 311. The arrangement of the slide seat and the slide rail 311 can improve the stability of the sliding portion 32 during movement.

[0047] For further information, see Figure 3The shuttle track 14 has a first zigzag edge on the side facing the docking track 33. The first zigzag edge includes a vertical edge 141, a transverse edge 142, a longitudinal edge 143, a first oblique edge 144, and a second oblique edge 145. The vertical edge 141 is an edge extending in the vertical direction, the transverse edge 142 is an edge extending in the transverse direction, and the longitudinal edge 143 is an edge extending in the longitudinal direction. The first oblique edge 144 and the second oblique edge 145 are both arranged in the horizontal direction. The docking track 33 has a second zigzag edge 331 on the side facing the shuttle track 14. The second zigzag edge 331 is configured to mate with and abut against the first zigzag edge.

[0048] When the docking track 33 is docked with the shuttle track 14, the horizontal edge 142 can prevent the docking track 33 from moving downward, thereby ensuring the vertical alignment of the docking track 33 and the shuttle track 14; the first bevel edge 144 and the second bevel edge 145 can prevent the docking track 33 from moving longitudinally relative to the shuttle track 14; thereby, the docking accuracy and stability of the docking track 33 and the shuttle track 14 are improved, facilitating a smooth transition of the shuttle.

[0049] For further information, see Figure 2 The docking track 33 is fixed with a limit structure 332 at one end away from the shuttle track 14. When the shuttle vehicle moves onto the docking track 33, the limit structure 332 can limit the shuttle vehicle from moving further away from the shuttle track 14, preventing the shuttle vehicle from falling from the docking track 33, thereby improving safety.

[0050] Furthermore, the fixed portion 31 is provided with a detection device at one end away from the shelf, and the detection device is used to detect whether the shuttle vehicle is parked in place, which is beneficial to improving the operational reliability of the entire layer-changing elevator. Figure 2 In this embodiment, the detection device includes an infrared transmitter 312 installed on one side of the fixing portion 31 and an infrared receiver 313 installed on the other side of the fixing portion 31. When the shuttle vehicle blocks the infrared transmitter 312 and the infrared receiver 313, it indicates that the shuttle vehicle has stopped in place.

[0051] Example 3:

[0052] This embodiment 3 further improves embodiment 2:

[0053] The system further includes a blocking device, which prevents the shuttle from passing when the docking track 33 is not docked with the shuttle track 14.

[0054] See also Figure 3 and Figure 4 In this embodiment, the blocking device includes a mounting seat 42, a docking block 43, a blocking block, and a return spring.

[0055] See also Figure 3A push block 41 is fixedly installed on the side of one end of the docking track 33 close to the shuttle track 14.

[0056] See also Figure 3 The mounting seat 42 is fixedly mounted on one end side of the shuttle track 14 close to the docking track 33 .

[0057] See also Figure 3 and Figure 4 The docking block 43 is arranged on the side of the mounting seat 42 away from the shuttle track 14. The mounting seat 42 is fixedly connected to the first rotating shaft 421. The docking block 43 is rotatably connected to the first rotating shaft 421. The docking block 43 is rotatably connected to the roller 431 on the upper part of the side facing the push block 41. The docking block 43 is provided with a slope 432 on the side away from the push block 41.

[0058] See also Figure 4 The docking block 43 is provided with a stop rod 44 at the lower portion of the side facing the push block 41 , and the stop rod 44 is fixedly connected to the mounting seat 42 .

[0059] See also Figure 3 and Figure 4 The blocking block is located on the side of the docking block 43 facing away from the push block 41. The blocking block includes a vertically arranged toggle lever 45 and a blocking lever 46. The toggle lever 45 and the blocking lever 46 are integrally structured. The toggle lever 45 is rotatably connected to the mounting base 42 via a second rotating shaft (not shown). The axial direction of the second rotating shaft is perpendicular to the axial direction of the first rotating shaft 421, so that the docking block 43 and the blocking block rotate perpendicularly. The top surface of the toggle lever 45 abuts the inclined surface 432. The blocking lever 46 is located above the shuttle track 14.

[0060] The return spring includes a first torsion spring (not shown in the figure) and a second torsion spring (not shown in the figure).

[0061] The first torsion spring is wound around the first rotating shaft 421. One end of the first torsion spring is fixedly connected to the docking block 43, and the other end of the first torsion spring is fixedly connected to the first rotating shaft 421. The first torsion spring is used to reset the docking block 43 after rotation.

[0062] The second torsion spring is wound around the second rotating shaft, one end of the second torsion spring is fixedly connected to the toggle rod 45, and the other end of the second torsion spring is fixedly connected to the mounting base 42. The second torsion spring is used to reset the toggle rod 45 and the blocking rod 46 after rotation.

[0063] When the docking track 33 gradually docks with the shuttle track 14, the push block 41 pushes the roller 431 to make the docking block 43 overcome the elastic force of the first torsion spring and rotate downward, and the inclined surface 432 presses down the toggle rod 45, and the toggle rod 45 overcomes the elastic force of the second torsion spring and rotates in the direction away from the shuttle track 14, and the toggle rod 45 drives the blocking rod 46 to rotate in the direction away from the shuttle track 14, so that the blocking rod 46 gradually changes from a state horizontally placed above the shuttle track 14 to a vertical state.

[0064] When the docking track 33 and the shuttle track 14 are docked, the blocking rod 46 rotates to a vertical position, releasing the blocking rod 46 from blocking the shuttle track 14. At this time, the push block 41 abuts against the stop rod 44, which prevents the push block 41 from further rotation. Because the blocking rod 46 no longer blocks the shuttle track 14, the shuttle can move smoothly between the docking track 33 and the shuttle track 14.

[0065] When the docking track 33 leaves the shuttle track 14, the pushing block 41 gradually moves away from the docking block 43, and the docking block 43 is reversed and reset under the elastic force of the first torsion spring. The blocking block is reversed and reset under the elastic force of the second torsion spring, and the blocking rod 46 in the blocking block is rotated again to the top of the shuttle track 14. At this time, the shuttle will be blocked by the blocking rod 46, and the shuttle cannot move between the docking track 33 and the shuttle track 14.

[0066] As can be seen from the above description, when the docking track 33 and the shuttle track 14 are not fully docked, the blocking device can prevent the shuttle from moving between the docking track 33 and the shuttle track 14. Only after the docking track 33 and the shuttle track 14 are fully docked, the blocking device allows the shuttle to move between the docking track 33 and the shuttle track 14. This improves the operational reliability of the entire floor-changing elevator.

[0067] In this embodiment, the push block 41 is arranged on the docking track 33, and the mounting seat 42 in the blocking device is arranged on the shuttle track 14. In addition to this arrangement, the installation positions of the push block 41 and the mounting seat 42 can also be swapped, that is, the push block 41 is set on the shuttle track 14, and the mounting seat 42 is set on the docking track 33, which can also achieve the blocking effect.

[0068] Example 4:

[0069] This embodiment 4 improves the lifting device in embodiment 1:

[0070] The lifting device also includes an anti-sway clamping wheel assembly, which is mounted on the base 11 and includes two clamping wheels (not shown) that clamp the lifting belt 23 from the sides. The anti-sway clamping wheel assembly prevents the lifting belt 23 from moving, improving the stability and reliability of the lifting belt 23 wrapped around the synchronous pulley, thereby helping to improve the operational reliability of the entire floor-changing elevator.

[0071] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
