Technical Field

[0001] The present application relates to the technical field of intelligent logistics equipment, and in particular to a sunken guide rail device for RGV. Background Art

[0002] RGV, the abbreviation of Rail Guided Vehicle, is also called rail shuttle vehicle. It is a rail shuttle vehicle used in warehouse logistics systems. RGV is suitable for high-density storage warehouses. RGV can pass quickly on the designed track to realize the handling and movement of goods, especially in some narrow alleys, RGV can shuttle freely along the predetermined track.

[0003] At present, the common guide devices on RGV mainly include guide rails and guide pulleys. The guide rails are laid on the ground, and the guide pulleys are rollingly or slidingly arranged in the guide rails. When the RGV moves, the guide rails and the guide pulleys cooperate to guide the RGV so that the RGV reciprocates along the length direction of the guide rails.

[0004] Regarding the above-mentioned related technologies, since the existing guide rails are often laid on the ground, which causes the guide rails to protrude from the ground, the existence of the guide rails will hinder the passage of pedestrians, AGVs and other equipment on the ground. Among them, AGV is the abbreviation of Automated Guided Vehicle, also known as automatic guided transport vehicle, automatic guided transport vehicle. AGV is an industrial vehicle that loads goods automatically or manually, automatically drives along a set route or pulls a cargo trolley to a designated location, and then loads and unloads goods automatically or manually. Summary of the invention

[0005] The present application provides a sunken guide rail device for RGV, the purpose of which is to reduce the obstruction to the normal movement of pedestrians, AGV carts and other traffic equipment.

[0006] The present application provides a sunken guide rail device for RGV using the following technical solution:

[0007] A sunken guide rail device for RGV, comprising a trolley body, the trolley body being provided with a driving wheel group for driving the trolley body to move; a guide rail, the guide rail is pre-buried in a floor, and the guide rail is located at the lower side of the trolley body, the upper side of the guide rail is lower than the upper side of the floor or the upper side of the guide rail is flush with the upper side of the floor; a guide member, the guide member is arranged between the trolley body and the guide rail, and the upper end of the guide member is connected to the trolley body, and the lower end of the guide member is slidably connected to the guide rail along the length direction of the guide rail.

[0008] By adopting the above technical solution, firstly, the coordinated arrangement of the trolley body, the guide rail and the guide member can meet the function of the RGV. Secondly, since the guide rail is pre-buried in the floor and is arranged by the positional relationship between the upper side of the guide rail and the upper side of the floor, the flatness of the floor can be improved, and then when pedestrians, AGV trolleys and other traffic equipment move on the floor, the obstacles to the normal movement of pedestrians, AGV trolleys and other traffic equipment by the guide rail can be reduced.

The length direction of the bus bar is arranged along the length direction of the guide rail, the brushes are in contact with the bus bar, and the brushes are slidingly connected to the bus bar along the length direction of the bus bar.

[0010] By adopting the above technical solution, the brush and the busbar are arranged in coordination. When the trolley body moves along the length direction of the guide rail, the brush and the busbar are in sliding contact. At this time, the busbar can supply power to the trolley body through the brush, so that the RGV can be charged in real time and uninterruptedly during use, so that the RGV can work uninterruptedly.

[0011] Optionally, the lower end of the guide member is detachably connected to the guide rail.

[0012] By adopting the above technical solution, the guide member and the guide rail can be detachably connected, which is convenient for replacing the guide member and installing the vehicle body. At the same time, when the guide member and the guide rail are connected, the vehicle body can be used as an RGV; and when the guide member and the guide rail are removed, the vehicle body can be used as an AGV.

[0014] By adopting the above technical solution, the opening of the installation long groove provides space for the guide wheel, ensuring that the guide rail can be located between the two guide wheels. Through the cooperation of the guide rail and the two guide wheels, the guiding function can be achieved.

[0015] Optionally, the guide member further includes a lifting drive member, the lifting drive member is disposed on the trolley body, the two guide wheels are rotatably connected to the lifting drive member, and the lifting drive member is used to drive the guide wheels to move in a vertical direction.

[0016] By adopting the above technical solution, the setting of the lifting drive can drive the guide wheel to move in the vertical direction. When the lifting drive drives the two guide wheels to descend, the two guide wheels are inserted into the installation slots. At this time, the guide rail is located between the two guide wheels. The guide rail has a guiding function for the trolley body and can meet the function of the RGV trolley. When the lifting drive drives the two guide wheels to rise, the guide wheels are pulled out of the installation slots. At this time, the guide rail is separated from the guide wheels, and the RGV trolley can be used as an AGV trolley.

[0017] Optionally, two mounting seats are provided on the lower side of the trolley body, the mounting seats are arranged in one-to-one correspondence with the guide wheels, and the guide wheels are rotatably set on the corresponding mounting seats; the two mounting seats are both slidably connected to the trolley body, and the trolley body is provided with a distance adjustment drive component for driving the two mounting seats to move toward or away from each other.

[0018] By adopting the above technical solution, firstly, the installation of the mounting seat can realize the installation of the guide wheel. Secondly, the installation of the distance adjustment drive assembly can adjust the distance between the two mounting seats so that the spacing distance between the guide wheels can meet the requirements of guide rails of different widths.

[0019] Optionally, a buffer slider is provided on the mounting seat, and the buffer slider is slidably connected to the corresponding mounting seat along the width direction of the guide rail, and the guide wheel is rotatably set on the corresponding buffer slider; a buffer spring is provided on the mounting seat, and the buffer spring is located on the side of the buffer slider away from the guide rail, and one end of the buffer spring is connected to the buffer slider, and the other end is connected to the mounting seat.

[0020] By adopting the above technical solution, the buffer slider and the buffer spring are arranged in coordination, when the trolley body receives lateral force, the guide rail will contact the corresponding guide wheel, so that the corresponding buffer slider will slide on the corresponding mounting seat, and the corresponding buffer spring will be compressed, which can realize the buffering function and prevent the corresponding guide wheel from breaking due to lateral pressure.

[0021] Optionally, a pre-stressed part is arranged between the two mounting seats, and the pre-stressed part includes an intermediate slider, two slides and two intermediate rods, the slides are arranged in a one-to-one correspondence with the mounting seats, the slides are slidably connected with the corresponding mounting seats along the width direction of the guide rail, the slides are located on the side of the corresponding buffer slider facing the guide rail, and the slides are in contact with the corresponding buffer slider; the intermediate slider is slidably connected with the corresponding trolley body along the length direction of the guide rail, the intermediate rods are arranged in a one-to-one correspondence with the slides, and one end of the intermediate rod is rotatably connected with the corresponding skateboard, and the other end is rotatably connected with the intermediate slider; a distance-increasing driving member is arranged on the trolley body, the driving direction of the distance-increasing driving member is arranged along the length direction of the guide rail, and the driving shaft of the distance-increasing driving member is in contact with the intermediate slider.

[0022] By adopting the above technical solution, firstly, the pre-pressing member is arranged by the cooperation of the slide plate, the intermediate rod and the intermediate slider, and when the intermediate slider slides along the length direction of the guide rail, under the action of the intermediate rod, the two slide plates will move in opposite directions or towards each other along the width direction of the guide rail. Because under the action of the buffer spring, the buffer sliders will resist the corresponding slide plate, so that when the two slide plates move in opposite directions or towards each other, the two buffer sliders will also move synchronously, and then the two guide wheels will also move synchronously.

[0023] Secondly, the distance-increasing driving member is set up so that under the action of two buffer springs, the two slide plates have a tendency to move toward each other, and under the action of two intermediate rods, the intermediate slider has a tendency to move toward the distance-increasing driving member. Based on such a structural setting, when the driving shaft of the distance-increasing driving member is extended, the distance-increasing driving member will slide against the intermediate slider, and the distance between the two guide wheels can be increased; and when the driving shaft of the distance-increasing driving member is retracted, under the action of two buffer springs, the two slide plates move toward each other, and the distance between the two guide wheels can be reduced, and the intermediate slider can slide back to its original position.

[0024] When the guide member and the guide rail need to be installed, the driving shaft of the distance-increasing driving member is extended, and the distance between the two guide wheels can be increased. This state facilitates the insertion of the guide rail between the two guide wheels. After that, when the driving shaft of the distance-increasing driving member is retracted, the two buffer sliders are reset under the action of the two buffer springs, and the two guide wheels can contact the guide rail. Therefore, such a structural setting facilitates the installation of the guide member and the guide rail, and can also adapt to guide rails of different widths.

[0025] Optionally, the distance increasing driving member is slidably connected to the trolley body, and the trolley body is provided with a compensation driving member for driving the distance increasing driving member to move along the length direction of the guide rail.

[0026] By adopting the above technical solution, since the distance adjustment drive assembly can adjust the distance between the two mounting seats, this will change the initial position of the middle slider. Therefore, the position of the distance increasing drive member can be adjusted through the compensation drive member to ensure that the distance increasing drive member can always drive the middle slider.

[0027] Optionally, the upper end of the guide member is slidably connected to the trolley body, and the trolley body is provided with a lateral shift driving member for driving the guide member to move along the width direction of the guide rail.

[0028] By adopting the above technical solution, the setting of the side shift drive can drive the mounting plate to move along the width direction of the guide rail, thereby changing the position of the guide member at the bottom of the trolley body, so that the position of the guide member can meet the actual position requirement of the guide rail.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. The present application provides pre-buried guide rails, which can improve the flatness of the floor, thereby reducing the obstruction of the guide rails to pedestrians, AGVs and other traffic equipment when they move on the floor.

[0042] When the trolley body 1 is working, the cooperation between the guide member 11 and the guide rail 2 realizes the guidance of the trolley body 1, so that the trolley can move along the length direction of the guide rail 2. In addition, since a single guide rail 2 is used, the space occupied by the guide rail 2 can be reduced, so that the trolley body 1 can pass through an extremely narrow passage.

[0043] In the present application, a driving wheel group and a supporting wheel group are provided at the bottom of the trolley body 1. The setting of the driving wheel group enables the trolley body 1 to move, and the setting of the supporting wheel group enables the trolley body 1 to support the trolley body 1. Radars are provided on both sides of the length direction of the trolley body 1, and the setting of the radar enables the trolley body 1 to have an obstacle avoidance function. A code reader is provided on one side of the length direction of the trolley body 1, and the setting of the code reader enables the trolley body 1 to read the QR code at a fixed point, thereby achieving precise positioning. Batteries, circuit boards and controllers are also integrated in the trolley body 1. The coordinated setting of the batteries, circuit boards and controllers can power other components, read information and perform control.

[0044] Reference Figure 1 and Figure 2 The guide rail 2 is embedded in the floor 100. In this embodiment, the guide rail 2 is made of I-beam. The upper side of the guide rail 2 is flush with the upper side of the floor 100, or the upper side of the guide rail 2 is located below the upper side of the floor 100 in the vertical direction. Such a structural setting can prevent the guide rail 2 from protruding from the ground, thereby reducing the impact of the guide rail 2 on the passage of pedestrians, AGVs and other equipment.

[0045] Reference Figure 1 and Figure 2 The guide member 11 includes a mounting plate 111, which is arranged at the lower side of the trolley body 1 and is fixedly connected to the trolley body 1. The guide member 11 also includes two guide wheels 112, the axial direction of the guide wheels 112 is arranged along the vertical direction, the two guide wheels 112 are arranged at intervals along the width direction of the guide rail 2, and the upper ends of the guide wheels 112 are rotatably connected to the mounting plate 111.

[0046] Reference Figure 1 and Figure 2 The floor 100 is provided with an installation slot 101, the guide rail 2 is arranged in the installation slot 101, and the upper side of the guide rail 2 is located on the upper side of the slot bottom of the installation slot 101 in the vertical direction. The two guide wheels 112 are both located in the installation slot 101, and the guide rail 2 is located between the two guide wheels 112 along its width direction, and the outer side wall of the guide wheel 112 is rollingly connected to the guide rail 2.

[0047] By installing the long groove 101, the guide rail 2 can be located between the two guide wheels 112, and when the trolley body 1 moves, the cooperation between the guide rail 2 and the two guide wheels 112 can guide the trolley body 1 so that the trolley body 1 moves along the length direction of the guide rail 2.

[0048] Reference Figure 1 and Figure 2 A lifting drive member 113 is provided between the mounting plate 111 and the guide wheel 112. In this embodiment, the lifting drive member 113 is an electromagnetic latch. One end of the lifting drive member 113 is connected to the mounting plate 111, and the other end is coaxially connected to the corresponding guide wheel 112.

[0049] The lifting drive 113 can drive the corresponding guide wheel 112 to move in the vertical direction. When the two guide wheels 112 are lowered, the two guide wheels 112 are inserted into the installation slot 101. At this time, the guide rail 2 is located between the two guide wheels 112. The guide rail 2 has a guiding function for the trolley body 1, which can meet the function of the RGV trolley. When the two guide wheels 112 are raised, the guide wheels 112 are pulled out of the installation slot 101. At this time, the guide rail 2 is separated from the guide wheel 112, and the RGV trolley can be used as an AGV trolley.

[0050] Reference Figure 1 and Figure 2 A charging mechanism 3 is also provided between the guide rail 2 and the mounting plate 111. The charging mechanism 3 includes a busbar 31, which is preset on the upper side of the guide rail 2 and arranged along the length direction of the guide rail 2. The charging mechanism 3 also includes a brush 32, which is arranged on the lower side of the mounting plate 111. The brush 32 is electrically connected to the battery inside the trolley body 1, and the lower side of the brush 32 is in contact with the busbar 31. The brush 32 is slidably connected to the busbar 31 along the length direction of the busbar 31, and the brush 32 is electrically connected to the busbar 31.

[0051] The structural setting of the charging mechanism 3 enables the RGV to be charged in real time during use, which enables the RGV to work uninterruptedly.

[0052] Reference Figure 1 and Figure 2 A vertical driving member 33 is disposed between the brush 32 and the mounting plate 111 . In this embodiment, the vertical driving member 33 is an electromagnetic latch. One end of the vertical driving member 33 is connected to the mounting plate 111 , and the other end is connected to the brush 32 .

[0053] The vertical drive member 33 can drive the brush 32 to move in the vertical direction. When the vertical drive member 33 drives the brush 32 to descend, the brush 32 can contact the bus bar 31 to realize power supply. Conversely, when the vertical drive member 33 drives the brush 32 to rise, the brush 32 is separated from the bus bar 31, which facilitates the disassembly and replacement of the brush 32.

[0054] The implementation principle of the embodiment of the present application is: when the guide rail 2 is located between the two guide wheels 112, the guide rail 2 can guide the trolley body 1, and during the normal operation of the trolley body 1, the charging mechanism 3 can supply power to the trolley body 1 in real time to ensure that the trolley body 1 can achieve uninterrupted operation.

[0055] Example 2: A sunken guide rail device for RGV, referring to Figure 1 and Figure 3The difference between this embodiment and the first embodiment is that the busbar 31 is located on one side wall in the width direction of the guide rail 2, and the busbar 31 is located in the installation slot 101. The brush 32 is located on one side in the width direction of the guide rail 2, and the brush 32 is located in the installation slot 101. A mounting frame 34 is provided between the mounting plate 111 and the brush 32, and the mounting frame 34 is rotatably connected to the mounting plate 111. One side of the brush 32 in the length direction is connected to the mounting frame 34, and the other side is in contact with the busbar 31. A rotating drive member 35 is provided on the mounting frame 34, and the rotating drive member 35 adopts a motor, and the output shaft of the rotating drive member 35 is connected to the mounting frame 34. The setting of the mounting frame 34, on the one hand, ensures that the brush 32 can penetrate into the installation slot 101, and on the other hand, through the cooperation of the rotating drive member 35 and the mounting frame 34, ensures that the brush 32 can rotate to contact the busbar 31 or rotate to separate from the busbar 31.

[0056] The implementation principle of the embodiment of the present application is: since the busbar 31 and the brush 32 are both located in the installation slot 101, this can prevent the busbar 31 from being exposed on the upper side of the guide rail 2. On the one hand, this protects the busbar 31; on the other hand, it prevents leakage.

[0057] Example 3: A sunken guide rail device for RGV, referring to Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the mounting plate 111 is slidably connected to the lower side of the trolley body 1 along the width direction of the guide rail 2, and a side shift drive member 12 is arranged between the lower side of the trolley body 1 and the mounting plate 111.

[0058] The setting of the side shift drive member 12 can drive the mounting plate 111 to move along the width direction of the guide rail 2, thereby changing the position of the guide member 11 on the lower side of the trolley body 1, so that the position of the guide member 11 can meet the actual position requirement of the guide rail 2.

[0059] Reference Figure 4 and Figure 5 An adjustable mounting mechanism 4 is also provided on the mounting plate 111. The adjustable mounting mechanism 4 includes two mounting seats 41. The two mounting seats 41 are both arranged on the lower side of the mounting plate 111. The mounting seats 41 are arranged in a one-to-one correspondence with the guide wheels 112. The guide wheels 112 and the corresponding lifting drive members 113 are both arranged on the lower side of the corresponding mounting seats 41.

[0060] Reference Figure 4 and Figure 5, the mounting plate 111 is also provided with a pitch-adjusting drive assembly 42, which includes a base 421, a drive motor 422 and two screw rods 423. The length direction of the base 421 is arranged along the width direction of the guide rail 2, the two screw rods 423 are coaxially connected, and the axial direction of the screw rods 423 is arranged along the length direction of the base 421, the thread rotation directions of the two screw rods 423 are opposite, and the two screw rods 423 are both rotatably connected to the base 421, the drive motor 422 is arranged on the base 421, and one end of the screw rod 423 is coaxially connected to the output shaft of the drive motor 422.

[0061] Driven by the distance adjustment drive assembly 42, the two mounting seats 41 can move toward or away from each other, which can adjust the distance between the two guide wheels 112, thereby increasing the size of the guide rail 2 that the guide member 11 of the present application can adapt to, thereby increasing the scope of application of the guide member 11 of the present application.

[0062] Reference Figure 4 and Figure 5 , buffer components 43 are provided on both mounting seats 41, and the buffer components 43 include a buffer slider 431 and a buffer spring 432. A buffer groove 433 is opened on the lower side of the mounting seat 41, and the length direction of the buffer groove 433 is arranged along the width direction of the guide rail 2. The buffer slider 431 is arranged in the buffer ring groove, and the buffer slider 431 is slidably connected to the inner wall of the buffer groove 433 along the length direction of the buffer groove 433. The buffer spring 432 is located in the buffer groove 433, and the length direction of the buffer spring 432 is arranged along the length direction of the buffer groove 433. One end of the buffer spring 432 is connected to the buffer slider 431, and the other end is connected to an inner wall of the buffer groove 433 in the length direction.

[0063] Furthermore, along the width direction of the guide rail 2, the buffer slide blocks 431 in the two mounting seats 41 are located between the two buffer springs 432. The lifting drive member 113 and the corresponding guide wheel 112 are both disposed on the corresponding buffer slide blocks 431.

[0064] The arrangement of the buffer assembly 43 means that when the trolley body 1 is subjected to a lateral force, the guide rail 2 will contact the corresponding guide wheel 112, thereby causing the corresponding buffer slider 431 to slide in the buffer slot 433, and the buffer spring 432 to compress. Such a structural arrangement can protect the guide wheel 112 and prevent the guide wheel 112 from being broken due to the lateral force.

[0065] Reference Figure 5 and Figure 6An elastic clamping assembly 44 is also provided between the two mounting seats 41. The elastic clamping assembly 44 includes a pre-pressing member 441. The pre-pressing member 441 includes an intermediate slider 4411, two intermediate rods 4412 and two slides 4413. The slides 4413 are provided in a one-to-one correspondence with the buffering chute 433. The slides 4413 are provided in the corresponding buffering chute 433, and the slides 4413 are slidably connected with the inner wall of the corresponding buffering chute 433 along the length direction of the buffering chute 433.

The intermediate slider 4411 is slidably connected with the lower side of the mounting plate 111 along the length direction of the guide rail 2.

[0066] When the middle slider 4411 slides along the length direction of the guide rail 2, the middle rod 4412 and the slide plate 4413 are matched to each other so that the two slide plates 4413 can move toward each other or move away from each other.

[0067] Reference Figure 5 and Figure 6 The elastic snap-fit ​​assembly 44 also includes a distance-increasing driving member 442, which adopts an electromagnetic latch. The distance-increasing driving member 442 is arranged on the lower side of the mounting plate 111, and the axial direction of the distance-increasing driving member 442 is arranged along the length direction of the guide rail 2, and the driving shaft of the distance-increasing driving member 442 abuts against the middle slider 4411.

[0068] When the drive shaft of the distance increasing driving member 442 is extended, the distance increasing driving member 442 will move against the middle slider 4411, thereby causing the two sliders 4413 to move in opposite directions, thereby increasing the distance between the two guide wheels 112, and such a state facilitates the insertion of the guide rail 2 between the two guide wheels 112. When the drive shaft of the distance increasing driving member 442 is retracted, the two buffer sliders 431 are reset under the action of the two buffer springs 432, so that after the guide rail 2 is inserted into the two guide wheels 112, the two guide wheels 112 can resist the guide rail 2, and at this time the middle slider 4411 is reset.

[0069] Reference Figure 5 and Figure 6The elastic clamping assembly 44 also includes a compensating driving member 443, which is a linear module driven by a servo motor. The compensating driving member 443 is arranged on the lower side of the mounting plate 111, and the length direction of the compensating driving member 443 is arranged along the length direction of the guide rail 2. The compensating driving member 443 is located between the two mounting seats 41, and the distance increasing driving member 442 is arranged on the compensating driving member 443. Under the drive of the compensating driving member 443, the distance increasing driving member 442 can be driven to move along the length direction of the compensating driving member 443. A slot is provided on the middle slider 4411, and the slot is plugged and matched with the compensating driving member 443, and the compensating driving member 443 is slidably connected with the inner side wall of the corresponding slot along its own length direction, so the compensating driving member 443 can also guide the middle slider 4411.

[0070] Reference Figure 5 and Figure 6 , the mounting seats 41 are all provided with adjustment components 45, which include a pressure plate 451, which is arranged in the corresponding buffer chute 433, and the pressure plate 451 is slidably connected with the inner wall of the corresponding buffer chute 433 along the length direction of the buffer chute 433, and the buffer spring 432 is located between the corresponding buffer slider 431 and the pressure plate 451, and one end of the buffer spring 432 is connected with the corresponding buffer slider 431, and the other end is connected with the corresponding pressure plate 451. The adjustment component 45 also includes an adjustment screw 452, which is axially arranged along the length direction of the buffer chute 433, and the mounting seat 41 is provided with an adjustment hole 453 on one side away from the other mounting seat 41 along its own length direction, and the adjustment screw 452 is plugged and matched with the adjustment hole 453, and the adjustment screw 452 is threadedly connected with the inner wall of the adjustment hole 453, and one end of the adjustment screw 452 is in conflict with the corresponding pressure plate 451.

[0071] When the adjusting screw 452 is turned, the length of the adjusting screw 452 extending into the corresponding buffer groove 433 can be changed, so that the pressure plate 451 can be resisted from sliding in the corresponding buffer groove 433, and the compression distance of the buffer spring 432 can be changed at this time, which can change the resistance force between the corresponding guide wheel 112 and the side wall of the guide rail 2, thereby ensuring a stable connection between the guide member 11 and the guide rail 2.

[0072] The implementation principle of the embodiment of the present application is as follows: before installing the trolley body 1 to the corresponding guide rail 2, the position of the mounting plate 111 is adjusted by the side shift drive 12 according to the actual position of the guide rail 2, and then the distance between the two guide wheels 112 is adjusted by the distance adjustment drive assembly 42. After the distance adjustment between the two guide wheels 112 is completed, the compensation drive 443 correspondingly adjusts the position of the distance increasing drive 442 to ensure that the driving shaft of the distance increasing drive 442 can contact the middle slider 4411 at this time.

[0073] After that, when installing the trolley body 1, the distance adjustment drive assembly 42 works, and the two guide wheels 112 move in opposite directions. At this time, the distance between the two guide wheels 112 increases temporarily. When the guide rail 2 is located between the two guide wheels 112, the distance adjustment drive assembly 42 is reset, and the two guide wheels 112 move toward each other. At this time, the guide rail 2 is located between the two guide wheels 112, so that the trolley body 1 is installed on the guide rail 2.

[0074] After the trolley body 1 is mounted on the guide rail 2 , the pressure between the guide wheel 112 and the guide rail 2 is changed by turning the adjustment screw 452 to ensure the stability of the connection between the guide member 11 and the guide rail 2 .

The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
