Technical Field
[0001] The utility model relates to the technical field of warehousing, in particular to a linear push-pull turnout system. Background Art
[0002] With the increasing demand for automation, the application of automated stereoscopic warehousing is becoming increasingly widespread. The ring shuttle car is widely used in the automated stereoscopic warehouse industry due to its advantages such as strong expandability, high transfer efficiency, and flexible transfer. The conventional ring shuttle car system usually refers to setting up a closed loop, and the ring shuttle car moves back and forth in the ring track in one direction (clockwise or counterclockwise) to realize the connection of goods. This type of ring shuttle car system cannot realize the automatic operation of the faulty ring shuttle car to the fault repair area outside the ring track for repair, nor can it realize scheduling the redundant ring shuttle cars to the waiting area outside the ring track when the system flow is low, nor can it realize more flexible and efficient goods connection operation for the ring shuttle car system.
[0003] The turnout system can be extended to the fault repair area outside the ring shuttle car system and dock with the track in the fault area. The turnout system can be extended to the waiting area outside the ring shuttle car system and dock with the track in the waiting area. In addition, the turnout system can also flexibly change the track according to the process requirements to realize flexible and efficient goods connection operation. At present, some turnout systems have also been applied, but these turnout systems have large floor areas, complex structures, difficult installation and commissioning, high failure rates, and poor stability, and cannot play the role that the turnout could originally play. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is to provide a linear push-pull turnout system with a simple motion mechanism, a simple overall structure, simple installation and maintenance, high overall structural strength, flexible, stable and reliable operation, and low failure rate.
[0005] In order to solve the defects of the existing turnout systems on the market, such as large floor area, complex structure, difficult installation and commissioning, high failure rate, and poor stability, this solution designs a linear push-pull turnout system. The turnout system realizes the access of the curved track or the straight track in the system through the movement of the moving vehicle body moving left and right and the cooperation of the attached track swinging, so as to flexibly change the running path of the ring shuttle car. Various application process flows can be extended based on this linear push-pull turnout system, such as: the docking and conversion of the ring track and the track in the fault repair area; the docking and conversion of the ring track and the track in the waiting area; flexibly realizing the docking and conversion of the ring track and other external tracks to realize the optimal path picking and placing operation.
[0006] A linear push-pull turnout system described in this solution includes: a bottom mounting frame. A moving vehicle body is mounted on the bottom mounting frame through a horizontal sliding device, and the moving vehicle body can move horizontally in a straight line to the left or right relative to the bottom mounting frame through the horizontal sliding device. A pair of curved rails are fixedly arranged on the moving vehicle body: a first curved rail and a second curved rail. A pair of straight rails are also fixedly arranged on the moving vehicle body: a first straight rail and a second straight rail;
[0007] A pair of external connecting curved rails are fixedly arranged on the bottom mounting frame: a first external connecting curved rail and a second external connecting curved rail. A pair of external connecting straight rails are fixedly arranged on the bottom mounting frame: a first external connecting straight rail and a second external connecting straight rail; An auxiliary rail is mounted on the bottom mounting frame at the space between the pair of external connecting curved rails, the pair of external connecting straight rails and the moving vehicle body through a swinging mechanism. A curved rail docking rail and a straight rail docking rail are also fixedly arranged on the bottom mounting frame at the space between the auxiliary rail and the moving vehicle body; The auxiliary rail can swing around the vertical center line of the auxiliary rail through the swinging mechanism until the front end of the auxiliary rail is docked with the rear end of the straight rail docking rail and the rear end of the auxiliary rail is docked with the front end of the first external connecting straight rail, or the auxiliary rail can swing around the vertical center line of the auxiliary rail through the swinging mechanism until the front end of the auxiliary rail is docked with the rear end of the curved rail docking rail and the rear end of the auxiliary rail is docked with the front end of the second external connecting curved rail;
[0008] When the moving vehicle body moves through the horizontal sliding device to the rear end of the second curved rail to be docked with the front end of the curved rail docking rail, and the auxiliary rail swings through the swinging mechanism until the front end of the auxiliary rail is docked with the rear end of the curved rail docking rail and the rear end of the auxiliary rail is docked with the front end of the second external connecting curved rail, the rear end of the first curved rail is docked with the front end of the first external connecting curved rail, forming a 90° curved rail assembly for docking two mutually perpendicular straight rail tracks;
[0009] When the moving vehicle body moves through the horizontal sliding device to the rear end of the first straight rail to be docked with the front end of the straight rail docking rail, and the auxiliary rail swings through the swinging mechanism until the front end of the auxiliary rail is docked with the rear end of the straight rail docking rail and the rear end of the auxiliary rail is docked with the front end of the first external connecting straight rail, the rear end of the second straight rail is docked with the second external connecting straight rail, forming a straight rail assembly for docking two straight rail tracks on the same horizontal center line in the front-rear direction.
[0010] In order to accurately control whether the moving vehicle body has reached its position, in this solution, a first position detection switch and a second position detection switch are fixedly arranged on the bottom mounting frame, and a first detection plate is fixedly arranged on the moving vehicle body; when the moving vehicle body moves through the horizontal sliding device to the rear end of the second curved rail to be docked with the front end of the curved rail docking rail, the first detection plate will be within the sensing area of the second position detection switch, while when the rear end of the second curved rail and the front end of the curved rail docking rail are in an undocked state, the first detection plate is always outside the sensing area of the second position detection switch. Similarly, when the moving vehicle body moves through the horizontal sliding device to the rear end of the first straight rail to be docked with the front end of the straight rail docking rail, the first detection plate will be within the sensing area of the first position detection switch, while when the rear end of the first straight rail and the front end of the straight rail docking rail are in an undocked state, the first detection plate is always outside the sensing area of the first position detection switch.
[0011] In order to prevent the moving vehicle body from moving excessively, this solution also has at least one left end blocking member arranged on the left part of the base mounting frame. When the moving vehicle body moves through the horizontal sliding device to the rear end of the first straight rail to be docked with the front end of the straight rail docking rail, each left end blocking member contacts the left side wall of the moving vehicle body. Similarly, at least one right end blocking member is arranged on the right part of the base mounting frame. When the moving vehicle body moves through the horizontal sliding device to the rear end of the second curved rail to be docked with the front end of the curved rail docking rail, each right end blocking member contacts the right side wall of the moving vehicle body.
[0012] There are various forms of the horizontal sliding device structure. Here, considering factors such as the compactness of the overall installation space and the simplicity of operation, the horizontal sliding device with the following structure is selected: The moving vehicle body is installed on a pair of linear guide rail mounting seats on the bottom mounting frame through a pair of linear guide rails. An electric push rod is fixedly arranged on the bottom mounting frame, and the push rod end of the electric push rod is fixedly connected to the moving vehicle body.
[0013] There are various forms of the swing mechanism. Here, considering factors such as the compactness of the overall installation space, the simplicity of operation, and the smoothness of operation, the swing mechanism with the following structure is selected: A support shaft is vertically fixedly arranged on the base mounting frame. The attached rail is fixed to the turntable. A first bearing is embedded in the middle of the turntable. The turntable is arranged on the support shaft through the first bearing; One end of the driving rod is hinged to the moving vehicle body, the other end of the driving rod is hinged to one end of the swing rod, and the other end of the swing rod is arranged on the support shaft through a second bearing; The first bearing and the second bearing are axially positioned by an axial positioning member group; A first stop block and a second stop block are arranged on the outer side wall of the turntable, and a driving block is fixedly arranged on the swing rod. The driving block extends into the gap between the first stop block and the second stop block.
[0014] During the processing and manufacturing of components and the assembly and installation of each component, deviations are inevitable. Therefore, the positions of the first stop block and the second stop block are set to be adjustable. In this way, by adjusting the positions of the first stop block and the second stop block, the deviations can be compensated, ensuring the accurate and reliable rotation angle of the attached rail. Among them, the adjustable method adopts the following structure: the first stop block is arranged on the outer side wall of the turntable through the first sliding structure, and the first stop block can be displaced and adjusted along the circumferential direction of the outer side wall of the turntable through the first sliding structure. The second stop block is arranged on the outer side wall of the turntable through the second sliding structure, and the second stop block can be displaced and adjusted along the circumferential direction of the outer side wall of the turntable through the second sliding structure.
[0015] In order to accurately control whether the attached rail swings in place, in this solution, a third in-place detection switch is fixedly arranged on the rear side wall of the bent rail docking rail, and a second detection plate is fixedly arranged on the front side wall of the attached rail. When the attached rail swings to the front end of the attached rail to be docked with the rear end of the bent rail docking rail through the swinging mechanism, the second detection plate will be within the sensing area of the third in-place detection switch. When the front end of the attached rail and the rear end of the bent rail docking rail are not in the docked state, the second detection plate is always outside the sensing area of the third in-place detection switch. Similarly, a fourth in-place detection switch is fixedly arranged on the front side wall of the first external straight rail, and a third detection plate is fixedly arranged on the rear side wall of the attached rail. When the attached rail swings to the front end of the attached rail to be docked with the rear end of the straight rail docking rail through the swinging mechanism, the third detection plate will be within the sensing area of the fourth in-place detection switch. When the front end of the attached rail and the rear end of the straight rail docking rail are not in the docked state, the third detection plate is always outside the sensing area of the fourth in-place detection switch.
[0016] Further, in the aforementioned linear push-pull turnout system, the moving vehicle body is an integrally formed one-piece body structure, and a plurality of reinforcing rib plates are also arranged on the moving vehicle body.
[0017] The beneficial effects of the present utility model are as follows: the motion mechanism of the above linear push-pull turnout system is simple, the overall structure is simple, the occupied space is small, the installation and maintenance are simple, the overall structural strength is high, the operation is stable and reliable, and the failure rate is low. It can realize flexible and accurate conversion between the 90° bent rail docking of two mutually perpendicular straight rail tracks and the straight rail docking of two straight rail tracks on the same horizontal center line in the front-back direction.

[0030] The technical solution of the present utility model will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0031] For the convenience of description, in this embodiment, Figure 1 the direction shown on the left hand side is defined as "left", Figure 1 the direction shown on the right hand side is defined as "right", Figure 1 the direction shown on the upper side is defined as "front", Figure 1 the direction shown on the lower side is defined as "rear". All the direction words involving "left", "right", "front" and "rear" in this article shall be subject to this definition. It should be noted that the defined directions here are only for facilitating the description of the relative positions of the components, and do not limit the installation direction of the linear push-pull turnout system.
[0032] A linear push-pull turnout system described in this embodiment, as shown in Figure 1 , Figure 2 and Figure 7 , includes: a bottom mounting frame. The moving vehicle body 1 is installed on the bottom mounting frame through a horizontal sliding device, and the moving vehicle body 1 can move horizontally in a straight line to the left or right relative to the bottom mounting frame through the horizontal sliding device. A pair of curved rails 2 are fixedly arranged on the moving vehicle body 1: a first curved rail 21 and a second curved rail 22. A pair of straight rails 3 are also fixedly arranged on the moving vehicle body 1: a first straight rail 31 and a second straight rail 32.
[0033] In this embodiment, the moving vehicle body 1 is an integral body structure formed by one-piece cutting. A number of reinforcing rib plates are further provided on the moving vehicle body 1, so that while the moving vehicle body 1 achieves lightweight, the strength of the overall structure can be enhanced.
[0034] In this embodiment, the structure of the horizontal sliding device is as follows: The moving vehicle body 1 is installed on a pair of linear guide rail mounting seats 10 on the bottom mounting frame through a pair of linear guide rails. An electric push rod 11 is fixedly provided on the bottom mounting frame. The push rod 12 of the electric push rod 11 is in the left-right horizontal direction, and the end of the push rod 12 of the electric push rod 11 is fixedly connected to the moving vehicle body 1. Among them, the push rod 12 of the electric push rod 11 is supported by a number of push rod support seats 13. When the push rod 12 of the electric push rod 11 retracts to the left, the moving vehicle body 1 is pulled to move horizontally to the left. On the contrary, when the push rod 12 of the electric push rod 11 extends to the right, the moving vehicle body 1 is pushed to move horizontally to the right.
[0035] Among them, if a linear push-pull turnout system described in this embodiment is installed on the foundation / ground, then the bottom mounting frame here refers to the foundation / ground, and the moving vehicle body 1 is installed on a pair of linear guide rail mounting seats 10 on the foundation / ground through a pair of linear guide rails. If a linear push-pull turnout system described in this embodiment is installed in the air on the roadway, then the bottom mounting frame is a structure installed on the roadway rack or is composed of a part of the roadway supplemented with various mounting beams.
[0036] As Figure 1 、 Figure 2 、 Figure 3 and Figure 7 shown, a pair of external connecting curved rails 5 are fixedly provided on the bottom mounting frame: a first external connecting curved rail 51 and a second external connecting curved rail 52. A pair of external connecting straight rails 6 are fixedly provided on the bottom mounting frame: a first external connecting straight rail 61 and a second external connecting straight rail 62. The auxiliary rail 7 is installed on the bottom mounting frame at the space among a pair of external connecting curved rails 5, a pair of external connecting straight rails 6 and the moving vehicle body 1 through a swing mechanism. A curved rail docking rail 82 and a straight rail docking rail 81 are also fixedly provided on the bottom mounting frame at the space between the auxiliary rail 7 and the moving vehicle body 1. The auxiliary rail 7 can swing around the vertical center line of the auxiliary rail 7 through the swing mechanism until the front end of the auxiliary rail 7 is docked with the rear end of the straight rail docking rail 81 and the rear end of the auxiliary rail 7 is docked with the front end of the first external connecting straight rail 61, or the auxiliary rail 7 can swing around the vertical center line of the auxiliary rail 7 through the swing mechanism until the front end of the auxiliary rail 7 is docked with the rear end of the curved rail docking rail 82 and the rear end of the auxiliary rail 7 is docked with the front end of the second external connecting curved rail 52.
[0037] The swing mechanism described in this embodiment is as follows: As Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 andFigure 10 As shown, a support shaft 72 is vertically and fixedly arranged on the base mounting frame. The attached rail 7 is fixed to the turntable 71. A first bearing 711 is embedded in the middle of the turntable 71. The turntable 71 is arranged on the support shaft 72 through the first bearing 711. One end of the driving rod 74 is hinged to the moving vehicle body 1, and the other end of the driving rod 74 is hinged to one end of the swing rod 73. The other end of the swing rod 73 is arranged on the support shaft 72 through a second bearing 731. The first bearing 711 and the second bearing 731 are axially positioned on the support shaft 72 by an axial positioning part group. The circumferential positioning part group belongs to a conventional circumferential positioning means, so it will not be specifically described here. As Figure 4 and Figure 10 shown, a first stop block 712 and a second stop block 713 are arranged on the outer side wall of the turntable 71. A driving block 732 is fixedly arranged on the swing rod 73. The driving block 732 extends into the gap between the first stop block 712 and the second stop block 713.
[0038] During operation, when the moving vehicle body 1 moves to the right through the horizontal sliding device, as the moving vehicle body 1 moves to the right, the driving rod 74 also moves to the right, thereby pushing the swing rod 73 to swing clockwise. When the driving block 732 on the swing rod 73 does not touch the second stop block 713, the turntable 71 is in a stationary state. When the swing rod 73 swings clockwise until the driving block 732 on the swing rod 73 contacts the second stop block 713, as the swing rod 73 continues to swing clockwise, the driving block 732 on the swing rod 73 will push the second stop block 713, causing the turntable 71 to also rotate clockwise. When the moving vehicle body 1 moves to the right through the horizontal sliding device until the rear end of the second curved rail 22 is docked with the front end of the curved rail docking rail 82, the attached rail 7 swings clockwise to the position where the front end of the attached rail 7 is docked with the rear end of the curved rail docking rail 82 under the drive of the rotation of the turntable 71. At this time, the rear end of the first curved rail 21 is docked with the front end of the first docking curved rail 51, and the rear end of the attached rail 7 is docked with the front end of the second external curved rail 52. At this time, a pair of curved rails 2, the curved rail docking rail 82, the attached rail 7, and a pair of external curved rails 5 form a 90° curved rail assembly of two mutually perpendicular straight rail tracks: the first straight rail track 101 and the second straight rail track 102, as Figure 1 and Figure 2 shown is the state of the curved rail assembly.
[0039] Conversely, when the moving vehicle body 1 moves leftward through the horizontal sliding device, as the moving vehicle body 1 moves leftward, the driving rod 74 also moves leftward accordingly, thereby pushing the swing rod 73 to swing counterclockwise. When the driving block 732 on the swing rod 73 does not touch the first stop block 712, the turntable 71 remains stationary. When the swing rod 73 swings counterclockwise until the driving block 732 on the swing rod 73 contacts the first stop block 712, as the swing rod 73 continues to swing counterclockwise, the driving block 732 on the swing rod 73 will push the first stop block 712, causing the turntable 71 to also swing counterclockwise. When the moving vehicle body 1 moves leftward through the horizontal sliding device until the rear end of the first straight rail 31 is docked with the front end of the straight rail docking rail 81, the auxiliary rail 7 swings counterclockwise under the drive of the rotation of the turntable 71 until the front end of the auxiliary rail 7 is docked with the rear end of the straight rail docking rail 81. At this time, the rear end of the second straight rail 32 is docked with the second external straight rail 62, and the rear end of the auxiliary rail 7 is docked with the front end of the first external straight rail 61. At this time, a pair of straight rails 3, the straight rail docking rail 81, the auxiliary rail 7, and a pair of external straight rails 6 form a straight rail assembly for docking two straight rail tracks on the same horizontal center line in the front-rear direction: the first straight rail track 101 and the third straight rail track 103, as Figure 7 and Figure 8 shown is the state of the straight rail assembly.
[0040] During the processing and manufacturing of components and the assembly and installation of each component, deviations will inevitably occur. Therefore, the positions of the first stop block 712 and the second stop block 713 are set to be adjustable here. In this way, by adjusting the positions of the first stop block 712 and the second stop block 713, the deviation can be compensated, ensuring the accurate and reliable rotation angle of the auxiliary rail 7. Among them, the adjustable method adopts the following structure: the first stop block 712 is arranged on the outer side wall of the turntable 71 through the first sliding structure, and the first stop block 712 can be displaced and adjusted along the circumferential direction of the outer side wall of the turntable 71 through the first sliding structure. The second stop block 713 is arranged on the outer side wall of the turntable 71 through the second sliding structure, and the second stop block 713 can be displaced and adjusted along the circumferential direction of the outer side wall of the turntable 71 through the second sliding structure. Among them, the first sliding structure and the second sliding structure can adopt the common structure of an arc-shaped guide rail and a slider on the market, and then supplemented with bolts to lock the position of the slider and the arc-shaped guide rail, so as to achieve the purpose of locking the positions of the first stop block 712 and the second stop block 713 at the required positions.
[0041] At least one left-end blocking member 14 is provided on the left part of the base mounting bracket, and at least one right-end blocking member 15 is provided on the right part of the base mounting bracket. Considering the compactness of the overall structure, in this embodiment, a pair of curved rails 2 and a pair of straight rails 3 are preferably arranged alternately, that is, from left to right are the first curved rail 21, the first straight rail 31, the second curved rail 22, and the second straight rail 32 in sequence. When the moving vehicle body 1 moves leftward through the horizontal sliding device to the rear end of the first straight rail 31 to be docked with the front end of the straight rail docking rail 81, each left-end blocking member 14 contacts the left side wall of the moving vehicle body 1 to block the moving vehicle body 1 from continuing to move leftward, as Figure 8 shown. Conversely, when the moving vehicle body 1 moves rightward through the horizontal sliding device to the rear end of the second curved rail 22 to be docked with the front end of the curved rail docking rail 82, each right-end blocking member 15 contacts the right side wall of the moving vehicle body 1 to block the moving vehicle body 1 from continuing to move rightward, as Figure 2 shown.
[0042] In this embodiment, a first in-place detection switch 41 and a second in-place detection switch 42 are also fixedly provided on the base mounting bracket, and a first detection plate 43 is fixedly provided on the moving vehicle body 1. When the moving vehicle body 1 moves rightward through the horizontal sliding device to the rear end of the second curved rail 22 to be docked with the front end of the curved rail docking rail 82, the first detection plate 43 will be in the sensing area of the second in-place detection switch 42, as Figure 2 shown. Conversely, when the moving vehicle body 1 moves leftward through the horizontal sliding device to the rear end of the first straight rail 31 to be docked with the front end of the straight rail docking rail 81, the first detection plate 43 will be in the sensing area of the first in-place detection switch 41, as Figure 8 shown.
[0043] Both the first in-place detection switch 41 and the second in-place detection switch 42 are connected to the control system, and the detected signals are transmitted to the control system through the first in-place detection switch 41 and the second in-place detection switch 42, and the control system issues corresponding instructions according to the received signals.
[0044] A first blocking member 16 and a second blocking member 17 are fixedly provided on the base mounting seat. When the attached rail 7 swings clockwise through the swinging mechanism to the front end of the attached rail 7 to be docked with the rear end of the curved rail docking rail 82, the left side wall of the attached rail 7 abuts against the first blocking member 16 to block the attached rail 7 from continuing to swing clockwise, as Figure 3 shown. Conversely, when the attached rail 7 swings counterclockwise through the swinging mechanism to the front end of the attached rail 7 to be docked with the rear end of the straight rail docking rail 81, the right side wall of the attached rail 7 abuts against the second blocking member 16 to block the attached rail 7 from continuing to swing counterclockwise, as Figure 9 shown.
[0045] A third in-place detection switch 44 is fixedly arranged on the rear side wall of the rear section of the curved rail docking rail 82, and a second detection plate 45 is fixedly arranged on the front side wall of the attached rail 7. Only when the attached rail 7 swings to the front end of the attached rail 7 to be docked with the rear end of the curved rail docking rail 82 through the swinging mechanism, the second detection plate 45 will be within the sensing area of the third in-place detection switch 44, as Figure 3 shown.
[0046] A fourth in-place detection switch 46 is fixedly arranged on the front side wall of the front section of the first externally-connected straight rail 61, and a third detection plate 47 is fixedly arranged on the rear side wall of the attached rail 7. When the attached rail 7 swings to the front end of the attached rail 7 to be docked with the rear end of the straight rail docking rail 81 through the swinging mechanism, at this time, the rear end of the attached rail 7 is docked with the front end of the first externally-connected straight rail 61, and the third detection plate 47 will be within the sensing area of the fourth in-place detection switch 46, as Figure 9 shown.
[0047] Both the third in-place detection switch 44 and the fourth in-place detection switch 46 are connected to the control system. The signals detected by the third in-place detection switch 44 and the fourth in-place detection switch 46 are transmitted to the control system, and the control system issues corresponding instructions according to the received signals.
[0048] As Figure 5 and Figure 6 shown, in this embodiment, a front support wheel 9 is arranged at the bottom of the front section of the attached rail 7, and a front support seat 91 is fixedly arranged on the base mounting frame below the front section of the attached rail. The top surface of the front support seat 91 is a first support surface 92 for the front support wheel 9 to roll and contact. A rear support wheel 93 is arranged at the bottom of the rear section of the attached rail 7, and a rear support seat 94 is fixedly arranged on the base mounting frame below the rear section of the attached rail 7. The top surface of the rear support seat 94 is a second support surface for the rear support wheel 93 to roll and contact.
[0049] In summary, the moving mechanism of the above linear push-pull turnout system is simple, the structure is simple, the installation and maintenance are simple, the overall structural strength is high, the operation is stable and reliable, and the failure rate is low. It can achieve flexible and accurate conversion between the 90° curved rail docking of two mutually perpendicular straight rail tracks and the straight rail docking of two straight rail tracks on the same horizontal center line in the front and rear directions.
[0050] The above is only a preferred embodiment of the present invention, and it is not any other form of limitation to the present invention. Any modification or equivalent change made according to the technical essence of the present invention still belongs to the scope protected by the present invention.
