Description

Technical Field

[0001] This application relates to the field of mechanical structures of logistics warehousing equipment, and particularly to a four-way shuttle car lifting and reversing mechanism. Background Art

[0002] In the modern industrial and logistics fields, the handling, storage, and transfer of goods are of crucial importance. With the continuous development of various industries, higher requirements have been put forward for the efficiency, flexibility, and accuracy of goods handling. An efficient goods handling and storage system can not only significantly improve the production efficiency of enterprises, reduce operating costs, but also enhance the competitiveness of enterprises in the market. Especially in the current booming development of industries such as e-commerce and manufacturing, the types and quantities of goods have increased sharply, and how to quickly and accurately complete the handling and storage of goods has become an urgent problem to be solved. For this reason, various handling and storage equipment have emerged and are constantly innovated and upgraded.

[0003] When solving the problems of direction conversion and height adjustment during the goods handling process, traditional technologies have adopted various means. One common method is to use a complex mechanical transmission structure, through the cooperation of a series of gears, chains, and connecting rods, to transmit power to different components to achieve the lifting and direction change of goods. For example, in some large-scale warehousing facilities, a special transmission system will be installed. When the goods need to change direction or lift height, the system will drive the corresponding mechanism to act.

[0004] However, these existing technical means have obvious deficiencies. The complex mechanical transmission structure is often large in volume, heavy in weight, high in installation and maintenance costs, and prone to failures during operation, resulting in low reliability of the equipment. Summary of the Invention

[0005] In order to reduce the complexity of the mechanical structure and thus improve the operating stability and reliability of the mechanism, the present invention provides a four-way shuttle car lifting and reversing mechanism.

[0006] The four-way shuttle car lifting and reversing mechanism provided by the present invention adopts the following technical solutions: A four-way shuttle car lifting and reversing mechanism, comprising a lifting plate, a lifting and reversing driving member and a reversing device. The lifting plate is horizontally arranged, and the lifting and reversing driving member is connected to the bottom of the lifting plate for driving the lifting plate to move in the vertical direction. The reversing device includes a first lifting assembly and a second lifting assembly. The first lifting assembly includes a first moving block, a lifting driving member and a first lifting rod. The first moving block is slidably connected to the lifting plate. The first end of the lifting driving member is fixedly connected to the first moving block. The first lifting rod is obliquely arranged. The top end of the first lifting rod is hinged to the second end of the lifting driving member, and the bottom end is hinged to the vehicle frame. The second lifting assembly includes a second moving block, a telescopic rod and a second lifting rod. The second moving block is slidably connected to the lifting plate. The first end of the telescopic rod is fixedly connected to the second moving block. The second lifting rod is obliquely arranged. The top end of the second lifting rod is hinged to the second end of the telescopic rod, and the bottom end is hinged to the vehicle frame. Lifting and reversing wheels are arranged on both sides of the vehicle frame and rotate synchronously through a shaft rod. The inclination directions of the first lifting rod and the second lifting rod are opposite, and their projections on the setting plane intersect with each other. The shaft rod passes through the tops of the first lifting rod and the second lifting rod and abuts against both the tops of the first lifting rod and the second lifting rod. When the lifting plate moves upward, it is used to lift the shaft rod.

[0007] By adopting the above technical solution, the mechanical structure of this four-way shuttle car has low complexity, and the operating stability and reliability of the mechanism are improved. Specifically, during the use of the four-way shuttle car, the lifting and reversing driving member drives the horizontally arranged lifting plate to move upward in the vertical direction. Since the first moving block and the second moving block are respectively slidably connected to the lifting plate, the first lifting rod and the second lifting rod are respectively hinged to the vehicle frame, and their inclination directions are opposite and their projections intersect with each other, and the shaft rod passes through their tops and abuts against them, the upward movement of the lifting plate can stably drive the first lifting rod and the second lifting rod to act, thereby realizing the lifting of the shaft rod and completing the lifting and reversing operation.

[0008] Preferably, it further includes a first support member. The first support member is provided with a first convex block, and the first convex block is provided with a support plane. A rolling block is connected to the shaft rod, and the rolling block is provided with a working plane. When the shaft rod is in the lifting state, the working plane abuts against the support plane for supporting the shaft rod.

[0009] By adopting the above technical solution, the shaft rod can be lifted by using the lifting plate, the lifting and reversing driving member and the reversing device. At the same time, the first support member is provided, and the support plane of the first convex block on the first support member abuts against the working plane of the rolling block on the shaft rod, which can support the shaft rod when the shaft rod is in the reversing state.

[0010] Preferably, the side wall of the first bump is an inclined surface, which is inclined away from the first support member from the bottom to the top. The rolling block is in rolling contact with the inclined surface of the first bump, and the first support member is slidably connected to the vehicle frame.

[0011] By adopting the above technical solution, by using the rolling contact between the inclined surface of the side wall of the first bump and the rolling block, and cooperating with the sliding connection between the first support member and the vehicle frame, it can better adapt to the position change during the movement of the shaft rod, ensure stable support and cooperation in related actions, and improve the stability and reliability of the lifting and reversing mechanism.

[0012] Preferably, it further includes a second support member. The second support member is provided with a second bump. The top surface of the second bump is an inclined surface that slopes downward from the end close to the second support member to the other end. A roller is rotatably connected to the shaft rod. When the shaft rod is in the lifted state, the roller is in contact with the top surface of the second bump. The second support member is connected with a driving unit, and the driving unit is used to drive the second support member to move. When the shaft rod moves from the lifted state to the non-lifted state, the second bump is used to separate the working plane from the supporting plane of the first bump.

[0013] By adopting the above technical solution, the setting of the second support member, when the shaft rod is in the lifted state, the top surface of its second bump is in contact with the roller on the shaft rod to play a partial supporting role. When the shaft rod moves from the lifted state to the non-lifted state, the inclined top surface of the second bump can separate the working plane of the rolling block on the shaft rod from the supporting plane of the first bump, and at the same time, the driving unit can drive the second support member to move to complete the corresponding action.

[0014] Preferably, the driving unit includes a transmission device and a reset device. The transmission device is arranged between the lifting plate and the second support member and is used to drive the second support member to move; the reset device is used to make the second support member return to its original position when it is not affected by the force of the transmission device.

[0015] By adopting the above technical solution, the transmission device is arranged between the lifting plate and the second support member, which can drive the second support member to move, so that the second support member cooperates with the lifting and reversing actions of the shaft rod; the reset device can make the second support member return to its original position when it is not affected by the force of the transmission device, ensuring the normal cyclic operation of the entire lifting and reversing mechanism.

[0016] Preferably, the transmission device includes a transmission assembly and a connecting frame. The transmission assembly includes a rack, a gear, a synchronous shaft, a mounting block, and a cam. The rack is vertically arranged, the top end of the rack is connected to the lifting plate, the gear meshes with the rack, both ends of the synchronous shaft are rotatably connected with mounting blocks, the mounting blocks are connected to the vehicle frame, the gear and the synchronous shaft are both sleeved on the synchronous shaft, the connecting frame is slidably connected to the second support member, and the cam is slidably abutted against the connecting frame.

[0017] By adopting the above technical solution, by using the meshing of the rack and the gear and the transmission of the synchronous shaft, the vertical movement of the lifting plate can be converted into the rotation of the cam, and then the cam is slidably abutted against the connecting frame to drive the second support member to move, cooperating with the entire four-way shuttle car lifting and reversing mechanism to realize the lifting and reversing functions.

[0018] Preferably, the connecting frame is connected to the first support member, and the first support member is connected to the reset device.

[0019] By adopting the above technical solution, the connection between the connecting frame and the first support member can transmit the movement of the connecting frame to the first support member. The first support member is connected to the reset device, so that the first support member can return to its original position by using the reset device when not affected by external forces, ensuring that the entire lifting and reversing mechanism can reliably return to the initial position after switching between different working states and maintaining stable operation.

[0020] Preferably, the reset device includes a first sliding block, a first sliding groove, a first spring, a second sliding block, a second sliding groove, and a second spring. The first sliding block is connected to the first support member, the second sliding block is connected to the second support member. The first sliding groove and the second sliding groove are both formed on the vehicle frame, and the bottom of the second sliding groove is inclined. The first sliding block and the first spring are both arranged in the first sliding groove, and the first sliding block is slidably connected to the vehicle frame to realize the sliding of the first support member. The second sliding block and the second spring are both arranged in the second sliding groove, and the second sliding block is slidably abutted against the second sliding groove to be used for realizing the movement of the second support member in a direction set at an angle with the horizontal direction.

[0021] By adopting the above technical solution, the cooperation of the first sliding block and the first sliding groove can realize the sliding of the first support member, and the first spring can enable the first support member to return to its original position when not affected by the force of the transmission device. The cooperation of the second sliding block and the second sliding groove with the inclined bottom can realize the movement of the second support member in a direction set at a certain angle with the horizontal direction, and the second spring can enable the second support member to return to its original position when not affected by the force of the transmission device.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1.

Detailed implementation manners

[0034] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments.

[0035] A four-way shuttle car jacking reversing mechanism, referring to Figure 1 and Figure 2 , includes a jacking plate 4, a jacking reversing driving part 3 and a reversing device 5. The jacking plate 4 is horizontally arranged, and the jacking reversing driving part 3 is fixedly connected to the bottom of the jacking plate 4 and is used to drive the jacking plate 4 to move in the vertical direction.

[0036] Referring to Figure 3 , the reversing device 5 includes a first lifting component 51 and a second lifting component 52. The first lifting component 51 includes a first moving block 511, a lifting driving part 512 and a first lifting rod 513. The jacking plate 4 is provided with a first chute 41 and a second chute 42. The first moving block 511 is arranged in the first chute 41 and is slidably connected to the jacking plate 4. The lifting driving part 512 is fixedly connected to the first moving block 511. The first lifting rod 513 is inclined. The top end of the first lifting rod 513 is hinged to the lifting driving part 512, and the bottom end is hinged to the frame 1. The lifting driving part 512 adopts a hydraulic cylinder or a pneumatic cylinder.

[0037] Referring to Figure 3, the second lifting component 52 includes a second moving block 521, a telescopic rod 522 and a second lifting rod 523. The second moving block 521 is arranged in the second chute 42 and is slidably connected to the jacking plate 4. The telescopic rod 522 is fixedly connected to the second moving block 521. The second lifting rod 523 is inclined. The top end of the second lifting rod 523 is hinged to the telescopic rod 522, and the bottom end is hinged to the vehicle frame 1. The inclination directions of the first lifting rod 513 and the second lifting rod 523 are opposite, and their projections on the setting plane intersect each other.

[0038] Refer to Figure 2 and Figure 3 , wherein, the jacking reversing wheel set 2 is arranged on both sides of the vehicle frame 1 and rotates synchronously through the shaft rod 21. There are two horizontally arranged shaft rods 21. Each jacking plate 4 is connected with two groups of reversing devices 5, and the two groups of reversing devices 5 on the same jacking plate 4 respectively correspond to the two shaft rods 21 one by one. The shaft rod 21 passes through the tops of the corresponding first lifting rod 513 and the second lifting rod 523, and abuts against the tops of the first lifting rod 513 and the second lifting rod 523. When the jacking plate 4 moves upward, it is used to realize the lifting of the shaft rod 21.

[0039] During the use of the four-way shuttle car, if the jacking reversing driving part 3 is started and the jacking driving part 512 is closed, the jacking reversing driving part 3 drives the horizontally arranged jacking plate 4 to move upward in the vertical direction. Since the first moving block 511 and the second moving block 521 are respectively slidably connected to the jacking plate 4, the first lifting rod 513 and the second lifting rod 523 are respectively hinged to the vehicle frame 1, and their inclination directions are opposite and the projections intersect each other, and the shaft rod 21 passes through and abuts against the tops of the first lifting rod 513 and the second lifting rod 523, so when the jacking plate 4 moves upward, it can stably drive the first lifting rod 513 and the second lifting rod 523 to act, thereby realizing the lifting of the shaft rod 21 and completing the jacking reversing operation. If the jacking reversing driving part 3 and the jacking driving part 512 are started at the same time, the jacking reversing driving part 3 drives the jacking plate 4 to move upward, and at this time the jacking driving part 512 only cooperates to perform an elongation operation of the same displacement distance, then the positions of the first lifting rod 513 and the second lifting rod 523 remain unchanged, and only the jacking plate 4 rises while the position of the shaft rod 21 remains unchanged.

[0040] Refer to Figure 3 , a plurality of bearings are arranged between the shaft rod 21 and the reversing device 5. The plurality of bearings are sleeved on the shaft rod 21 and respectively abut against the first lifting rod 513 or the second lifting rod 523, so as to reduce the friction force received by the shaft rod 21.

[0041] Refer to Figure 2, a limiting hole 11 is formed on the vehicle frame 1. There are four limiting holes 11, and the four limiting holes 11 are arranged in pairs and symmetrically formed on two opposite side walls of the vehicle frame 1. The limiting hole 11 is a long strip hole, and the length direction of the limiting hole 11 is parallel to the vertical direction. The shaft rod 21 passes through two opposite limiting holes 11 and is slidably connected to the vehicle frame 1. The limiting hole 11 realizes the limitation of the shaft rod 21.

[0042] Refer to Figure 2 , the lifting reversing drive member 3 adopts a hydraulic cylinder or an air cylinder, etc. Two lifting reversing drive members 3 are fixedly connected to the bottom of each lifting plate 4.

[0043] Refer to Figure 4 , it further includes a first support member 6 and a second support member 7. Each shaft rod 21 corresponds to a first support member 6 and a second support member 7. The first support member 6 and the second support member 7 are arranged at intervals along the axis of the shaft rod 21. The vehicle frame 1 is connected with a drive unit. Each shaft rod 21 corresponds to a set of drive units, and both the first support member 6 and the second support member 7 are connected to the corresponding drive unit. The drive unit is used to drive the first support member 6 and the second support member 7 to move in a preset direction.

[0044] Refer to Figure 5 , Figure 6 and Figure 7 , the drive unit includes a transmission device 8 and a reset device 9.

[0045] Among them, the transmission device 8 includes a transmission component 81 and a connecting frame 82. The transmission component 81 includes a rack 811, a gear 812, a synchronous shaft 813, a mounting block 814 and a cam 815. The rack 811 is arranged vertically, and its top end is fixedly connected to the bottom of the lifting plate 4. The gear 812 meshes with the rack 811. The synchronous shaft 813 is arranged horizontally, and both ends of it are rotatably connected with mounting blocks 814. The mounting blocks 814 are fixedly connected to the vehicle frame 1. Both the gear 812 and the cam 815 are sleeved on the synchronous shaft 813.

[0046] Refer to Figure 4 and Figure 5 , the connecting frame 82 is fixedly connected to the first support member 6; the connecting frame 82 is fixedly connected with a limiting slider 821. A limiting sliding groove 72 is formed on the second support member 7. The length direction of the limiting sliding groove 72 is parallel to the vertical direction. The limiting slider 821 is arranged in the limiting sliding groove 72 and is slidably connected to the second support member 7. The connecting frame 82 abuts against the cam 815.

[0047] When the four-way shuttle needs to change direction, the lifting and reversing drive component 3 is started and the lifting and reversing drive component 512 is closed. The lifting and reversing drive component 3 drives the lifting plate 4 to rise, and the lifting plate 4 drives the lifting drive component 512 and the telescopic rod 522 to move at the same time. Since the length of the lifting drive component 512 remains unchanged and the shaft rod 21 can only move in the vertical direction in the limiting hole 11, the shaft rod 21 is lifted by the first lifting rod 513, and the force on the telescopic rod 522 is small. Therefore, the second lifting rod 523 cooperates with the first lifting rod 513 to realize the lifting and reversing of the shaft rod 21.

[0048] In addition, the lifting plate 4 can also drive the rack 811 to rise, and the rack 811 drives the gear 812 to rotate, thereby rotating the synchronization shaft 813, and the cam 815 rotates accordingly. During the movement of the cam 815, the connecting frame 82 is driven to move, thereby driving the first support member 6 and the second support member 7 to move.

[0049] Reference Figure 6 and Figure 7 The reset device 9 includes a first sliding block 91, a first sliding groove 92, a first spring 93, a second sliding block 94, a second sliding groove 95 and a second spring 96. The first sliding block 91 is fixedly connected to the bottom of the first support member 6, the first sliding groove 92 is provided on the frame 1, the first sliding block 91 and the first spring 93 are both provided in the first sliding groove 92, and the first sliding block 91 is slidably connected to the frame 1. The first spring 93 is arranged horizontally, one end of the first spring 93 is fixedly connected to the first sliding block 91, and the other end is fixedly connected to the frame 1, so as to realize the sliding reset of the first support member 6.

[0050] The first sliding block 91 cooperates with the first sliding groove 92 to enable the first support member 6 to slide, and the first spring 93 enables the first support member 6 to return to its original position when not subject to the force of the transmission device 8 .

[0051] Reference Figure 6 and Figure 7 The second sliding block 94 is fixedly connected to the bottom of the second support member 7, and the second sliding groove 95 is also provided on the vehicle frame 1, and the bottom of the second sliding groove 95 is inclined. The second sliding block 94 and the second spring 96 are both provided in the second sliding groove 95, and the second sliding block 94 is in sliding contact with the second sliding groove 95, so as to realize the movement and reset of the second support member 7 in a direction set at a certain angle to the horizontal direction. The second spring 96 is inclined, and the inclination angle is the same as the inclination angle of the second sliding groove 95.

[0052] The second sliding block 94 cooperates with the second sliding groove 95 at the bottom of the inclined groove to realize the movement of the second support member 7 in a direction set at a certain angle to the horizontal direction. The second spring 96 can restore the second support member 7 to its original position when it is not subjected to the force of the transmission device 8.

[0053] ReferenceFigure 4 , Figure 8 and Figure 9 , a first convex block 61 is provided on the inner side wall of the opening of the first support member 6. A rolling block 22 is sleeved on the shaft rod 21, and the rolling block 22 is rotatably connected to the shaft rod 21. Wherein, the side wall of the first convex block 61 is an inclined surface, and is inclined away from the first support member 6 from the bottom to the top. The circumferential surface of the rolling block 22 abuts against the inclined surface of the first convex block 61.

[0054] A support plane 62 is provided at the top of the first convex block 61, and a working plane 221 is provided on the rolling block 22. When the shaft rod 21 is in the jacking state, the working plane 221 abuts against the support plane 62, playing a role in supporting the shaft rod 21.

[0055] During the process of jacking and reversing, when the jacking plate 4 starts to move upward, the shaft rod 21 drives the rolling block 22 to move upward, and the rolling block 22 remains in contact with the first convex block 61. Therefore, the rolling block 22 rotates accordingly. At the same time, the cam 815 drives the connecting frame 82 to move, and then drives the first support member 6 and the second support member 7 to move simultaneously. When the jacking plate 4 reaches the preset position, the shaft rod 21 reaches the preset position, the cam 815 also rotates 360 degrees, and the first spring 93 drives the first support member 6 to automatically reset. At this time, the working plane 221 is at the bottom and abuts against the support plane 62 to realize the support of the shaft rod 21.

[0056] Referring to Figure 4 and Figure 10 , a second convex block 71 is provided on the inner side wall of the opening of the second support member 7, and the top surface of the second convex block 71 is an inclined surface that slopes downward from near the second support member 7 to the other end. The shaft rod 21 is rotatably connected with a roller 23, and the roller 23 can be connected to the shaft rod 21 through a bearing, so that the roller 23 can rotate flexibly. When the shaft rod 21 is in the jacking state, the roller 23 abuts against the inclined top surface of the second convex block 71.

[0057] When the jacking plate 4 starts to move downward, the second support member 7 moves along the inclined direction of the bottom of the second sliding groove 95, and the roller 23 always remains in contact with the second convex block 71, which can provide support for the roller 23 and the shaft rod 21. Until the bottom end of the inclined top surface of the second convex block 71 coincides with the top end of the first convex block 61, the shaft rod 21 can cross the support plane 62 of the first convex block 61, and the working plane 221 of the rolling block 22 is away from the support plane 62, providing support for the next jacking and reversing.

[0058] When only the jacking plate 4 rises, the jacking driving member 512 cooperates to perform an elongation operation. The jacking plate 4 will drive the rack 81 to move, and then cause the first support member 6 and the second support member 7 to move. However, since only the jacking plate 4 rises and its upward movement distance is small, the shaft rod 21 will not cross the first convex block 61 and the second convex block 71, so it still has a limiting function for the shaft rod 21.

[0059] The implementation principle of this embodiment is as follows: The four-way shuttle car lifting and reversing mechanism solves the problems of large volume, high cost, and low reliability of the complex mechanical transmission structure in the traditional technology through the coordinated work of components such as the lifting plate 4, the lifting and reversing driving member 3, the reversing device 5, the first support member 6, and the second support member 7. The lifting and reversing driving member 3 and the lifting driving member 512 drive the lifting plate 4 to move vertically to provide power for the lifting of goods. The reversing device 5 uses a unique lifting component structure to cleverly achieve the change of the goods transportation direction. The first support member 6 and the second support member 7 support and assist the shaft rod 21 in different states to ensure the stability and accuracy of the whole process. This structure is relatively simple, reduces the probability of failure, reduces the installation and maintenance costs, improves the reliability and working efficiency of the equipment, and greatly improves and enhances the existing goods handling technology.

Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
