Technical Field

[0001] This invention relates to the field of warehousing technology, and in particular to a shuttle blocking device and a material transport system. Background Technology

[0002] A level-change shuttle is an automated device used in automated warehousing, logistics, or production scenarios. It travels along a fixed track to transfer materials between different levels of a three-dimensional racking system, or to retrieve materials within the same level. To ensure the safe operation of the shuttle on the track, especially when it needs to stop, turn, or cooperate with elevators for level changes, a blocking device is required to contact the shuttle and prevent it from moving forward. This allows for precise positioning of the shuttle or prevents collisions.

[0003] Currently, the blocking device usually uses an electromagnetic method to achieve the blocking function of the shuttle. However, the electromagnetic structure relies on a power supply and cannot work properly after a power failure, which will affect the operational stability of the shuttle. Summary of the Invention

[0014] A limiting elastic element is located between the base and the pressure contact member. When no pressure contact force is applied, the limiting elastic element keeps the pressure contact member stationary and the blocking member extended.

[0015] When the limiting elastic element is compressed by the car of the hoist, the pressure contact element rotates, causing the blocking telescopic assembly to move, so that the blocking element retracts.

[0016] In one optional embodiment, the blocking telescopic assembly includes:

[0028] The bottom, the first side, and the second side form an assembly space, in which the blocking telescopic component and the elastic rotary transmission component are located, wherein the elastic pressure contact unit is rotatably connected to the first side.

[0029] In one optional embodiment, the base further includes a connecting portion extending from the bottom toward a direction away from the blocking telescopic assembly, and the limiting elastic member is located between the connecting portion and the pressure contact member.

[0030] In one optional aspect of the invention, the shuttle blocking device further includes a cover that cooperates with the base to enclose the assembly space.

[0031] Based on a second aspect of the present invention, a material transport system is also provided, the material transport system comprising:

[0032] The shuttle blocking device as described in any of the above inventions;

[0033] The hoist includes a car for changing floors of a transport shuttle. The elastic pressure contact unit extends into the lifting area of ​​the car of the hoist. When the car of the hoist presses down on the elastic pressure contact unit, the elastic pressure contact unit rotates and drives the elastic rotation transmission assembly to output rotational driving force, thereby driving the blocking member to retract.

[0034] Without external force, the elastic pressure contact unit deforms and resets, driving the blocking member to extend and block the shuttle.

[0035] In one optional embodiment, the hoist further includes an abutment member disposed in the bottom region of the car and near the shuttle blocking device. The abutment member is used to abut against the elastic pressure contact unit and drive the elastic pressure contact unit to rotate.

Under no external force, the elastic pressure contact unit deforms and resets, driving the blocking member to extend and block the shuttle. Therefore, it can operate normally without any power source, improving the operational stability of the blocking device.

Detailed Implementation

[0045] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0046] A level-change shuttle is an automated device used in automated warehousing, logistics, or production scenarios. It travels along a fixed track to transfer materials between different levels of a three-dimensional racking system, or to retrieve materials within the same level. To ensure the safe operation of the shuttle on the track, especially when it needs to stop, turn, or cooperate with elevators for level changes, a blocking device is required to contact the shuttle and prevent it from moving forward. This allows for precise positioning of the shuttle or prevents collisions.

[0047] Currently, the blocking device usually uses an electromagnetic method to achieve the blocking function of the shuttle. However, the electromagnetic structure relies on a power supply and cannot work properly after a power failure, which will affect the operational stability of the shuttle.

[0048] To address the aforementioned technical problems, this invention proposes an embodiment that may include a base, a telescopic blocking assembly, a blocking member, and an elastic rotary transmission assembly. The base is mounted on a track, the telescopic blocking assembly is disposed on the base, and the blocking member is tractively connected to the telescopic blocking assembly to drive the blocking member to extend and retract during operation of the telescopic blocking assembly. The elastic rotary transmission assembly includes an elastic pressure contact unit rotatably connected to the base and a first transmission gear tractively connected to the elastic pressure contact unit. The first transmission gear meshes with the telescopic blocking assembly, and the elastic pressure contact unit extends into the lifting area of ​​the hoist's car. When the elastic pressure contact unit is pressed down by the hoist's car, the elastic pressure contact unit rotates, driving the first transmission gear to output a rotational driving force, which drives the blocking member to retract. Without external force, the elastic pressure contact unit deforms and resets, driving the blocking member to extend and block the shuttle. Thus, it can operate normally without any power source, improving the operational stability of the blocking device. Furthermore, the blocking mechanism automatically releases its obstruction of the shuttle car when the hoist car reaches the corresponding track level. This allows for precise blocking of the shuttle car during its journey across multiple tracks, preventing it from falling to the ground due to signal errors before the hoist car arrives, thus improving the shuttle car's operational stability and safety.

[0049] Reference Figure 1-4 This invention provides a shuttle car blocking device, which may include a base 1, a blocking telescopic assembly 2, a blocking member 3, and an elastic rotary transmission assembly 4. The base 1 is mounted on a track 9, the blocking telescopic assembly 2 is disposed on the base 1, and the blocking member 3 is tractively connected to the blocking telescopic assembly 2 so that when the blocking telescopic assembly 2 is working, it drives the blocking member 3 to extend and retract. The elastic rotary transmission assembly 4 may include an elastic pressure contact unit 41 rotatably connected to the base 1, and a first transmission gear 42 tractively connected to the elastic pressure contact unit 41. The first transmission gear 42 meshes with the blocking telescopic assembly 2, and the elastic pressure contact unit 41 extends into the lifting area of ​​the elevator car. When the elastic pressure contact unit 41 is pressed down by the elevator car 8, the elastic pressure contact unit 41 rotates, causing the elastic rotary transmission assembly 4 to output a rotational driving force, driving the blocking member 3 to retract. Without external force, the elastic pressure contact unit 41 deforms and resets, driving the blocking member 3 to extend and block the shuttle car.

[0050] In this embodiment of the invention, the base 1 is mounted on the track 9 to provide structural support for other components of the shuttle blocking device. The blocking telescopic assembly 2 is disposed on the base 1, and the blocking member 3 is tractively connected to the blocking telescopic assembly 2 so that when the blocking telescopic assembly 2 is working, it drives the blocking member 3 to perform telescopic movement. In one example, when the blocking telescopic assembly 2 moves along a first direction, it can drive the blocking member 3 to extend beyond the base 1, and when the blocking telescopic assembly 2 moves along a second direction, it can drive the blocking member 3 to retract back onto the base 1. When the blocking member 3 is in the extended state, it extends into the operating area of ​​the shuttle in the track 9, thereby preventing the shuttle from continuing to move.

[0051] For example, the blocking member 3 can be made of steel, and its surface can be hard chrome plated. The blocking member 3 has a thickness of 15 mm in the vertical direction, a length of 120 mm in the first direction, and a width of 80 mm in the third direction. The third direction is perpendicular to the first direction in the horizontal plane. When the blocking member 3 is in the extended state, the length of the blocking member 3 extending beyond the base can be 50 mm. Furthermore, the surface roughness of the blocking member 3 can be less than or equal to 0.8 micrometers. This allows the surface of the blocking member 3 to have a high degree of smoothness, reducing frictional losses between the blocking member 3 and the track 9, and between the blocking member 3 and the shuttle.

[0052] The elastic rotary transmission assembly 4 may include an elastic pressure contact unit 41 rotatably connected to the base 1, and a first transmission gear 42 drively connected to the elastic pressure contact unit 41. The first transmission gear 42 meshes with the blocking telescopic assembly 2 to input rotational driving force to the blocking telescopic assembly 2. The elastic pressure contact unit 41 extends into the lifting area of ​​the hoist's car. The hoist's car 8 is used for changing levels of the shuttle car. When a shuttle car needs to change levels, the hoist's car 8 descends to the track level where the shuttle car is located. Then, the shuttle car corresponding to the track level enters the car 8 along the track 9. The car 8 then descends or ascends to transfer the shuttle car to the corresponding track level.

[0053] The elastic pressure contact unit 41 extends into the lifting area of ​​the elevator car, so that when the elevator car 8 reaches the track level corresponding to the shuttle car to be changed, the elastic pressure contact unit 41 can be pressed down by the car 8, thereby driving the shuttle car blocking device to operate by external power.

[0054] In one example, when the elastic pressure contact unit 41 is pressed down by the elevator car 8, the elastic pressure contact unit 41 rotates and serves as the power input terminal of the elastic rotary transmission assembly 4, inputting rotary driving force and outputting rotary driving force through the first transmission gear 42. The blocking telescopic assembly 2, which is driven by the first transmission gear 42, drives the blocking member 3, which is driven by it, to retract under the rotational driving force. When the blocking member 3 is in the retracted state, it is not in the shuttle car's operating area, thus releasing the obstruction to the shuttle car. Therefore, when the elevator car 8 reaches the track level corresponding to the shuttle car, the shuttle car blocking device immediately releases the obstruction to the shuttle car. This allows the shuttle car waiting to change floors to enter the elevator car 8 for floor changing.

[0055] In another example, when the car 8 is raised or lowered and the pressure on the elastic pressure unit 41 is removed, the elastic pressure unit 41 deforms and resets without external force, that is, the elastic pressure unit 41 rotates in the opposite direction, driving the blocking member 3 to extend along the base 1. When the blocking member 3 is in the extended state, it can continue to block the shuttle.

[0056] In summary, the shuttle car blocking device can operate normally without any power source of its own, thus improving the operational stability of the blocking device. Utilizing the lifting kinetic energy of the car 8, energy conservation can be achieved. Furthermore, the blocking component 3 automatically releases its obstruction of the shuttle car when the elevator car 8 reaches the corresponding track level. Precise control of blocking or releasing the shuttle car can be achieved without the need for detection sensors on the car 8.

[0057] Furthermore, when the shuttle car reaches the track level corresponding to the floor to be changed via the car 8, it can avoid the shuttle car falling to the ground due to signal errors before the elevator car 8 arrives, thus improving the operational stability and safety of the shuttle car. Therefore, the shuttle car blocking device not only provides a stable blocking effect, but also, due to the structural cooperation between the long-lasting and wear-resistant transmission components, can be widely used in high-frequency, high-precision shuttle car blocking scenarios, and is adaptable to more complex working environments.

[0058] One or more optional embodiments of the invention, referred to Figure 2As shown, the elastic pressure contact unit 41 may include a pressure contact element 411, a rotating shaft 413, and a limiting elastic device 412. The pressure contact element 411 extends into the car lifting area of ​​the hoist. The rotating shaft 413 is operatively connected to the area of ​​the pressure contact element 411 away from the hoist and is rotatably connected to the base 1. The rotating shaft 413 is also operatively connected to the first transmission gear 42. The limiting elastic device 412 is located between the base 1 and the pressure contact element 411. When there is no pressure contact force, the limiting elastic device 412 keeps the pressure contact element 411 stationary and the blocking member 3 extended. That is, the first end of the limiting elastic device 412 is hinged to the base 1, the second end of the limiting elastic device 412 is hinged to the pressure contact element 411, and the limiting elastic device 412 limits the position of the pressure contact element 411. The limiting elastic device 412 may include a spring or a combination device used in conjunction with a spring.

[0059] The pressure contact element 411 can be made of carbon steel. For example, the extension length of the pressure contact element 411 along the first direction can be 150 mm, and the extension length along the third direction can be 20 mm. The third direction can be perpendicular to the first direction in the horizontal plane. The surface of the pressure contact element 411 can be subjected to a heat treatment process to improve its structural hardness, thereby improving its fatigue resistance and impact resistance.

[0060] In one example, when the pressure contact 411 is not pressed by the car 8 of the hoist, the pressure contact 411 is in a stationary state. When the pressure contact 411 is in a stationary state, the blocking member 3 is in an extended state and blocks the shuttle located on the track 9.

[0061] In another example, when the limiting elastic element 412 is compressed by the car 8 of the hoist, the abutting force generated by the car 8 on the pressing member 411 compresses or stretches the limiting elastic element 412, thereby causing the pressing member 411 to rotate around the rotating shaft 413, and drive the first transmission gear 42 to rotate synchronously through the rotating shaft 413, thereby driving the blocking telescopic assembly 2 to move, thereby driving the blocking member 3 to retract linearly onto the base 1.

[0062] Based on the above structural design, rotational driving force can be output without any power source component being installed in the elastic rotary transmission assembly 4 itself. Furthermore, the automatic reset of the pressure contact 411 is achieved through the component cooperation relationship between the limiting elastic element 412, the pressure contact 411, and the rotating shaft 413. This reduces the structural cost of the shuttle blocking device while improving the precise control of blocking or releasing the shuttle.

[0063] Furthermore, the meshing transmission between the first transmission gear 42 and the blocking telescopic assembly 2 can improve transmission smoothness and reduce power loss. The constant transmission ratio of the meshing transmission can also determine the relationship between the downward pressing stroke of the car 8 on the pressure contact member 411 and the blocking length of the blocking member 3, thereby achieving precise control of the blocking length of the blocking member 3.

[0064] In one or more embodiments of the invention, reference is made to Figure 2 As shown, the blocking telescopic component 2 may include a second transmission gear 21 and a rack 22. The second transmission gear 21 is rotatably connected to the elastic rotary transmission component 4, wherein the second transmission gear 21 is rotatably connected to the base 1. The second transmission gear 21 meshes with the first transmission gear 42, thereby transmitting the rotational driving force output by the first transmission gear 42 to the rack 22 meshing with the second transmission gear 21.

[0065] The rack 22 is fixedly connected to the blocking member 3. When the second transmission gear 21 rotates, it drives the rack 22 to move linearly along the radial direction of the second transmission gear 21, thereby driving the blocking member 3, which is fixedly connected to the rack 22, to extend out of the base 1 or retract into the base 1 in a linear motion. For example, when the pressure contact member 411 is pressed down by the elevator car 8, the limiting elastic member 412 is compressed, and when the pressure contact member 411 rotates downward around the rotating shaft 413, the rack 22 drives the blocking member 3 to retract into the base 1 in a linear motion, thereby removing the obstruction to the shuttle car, allowing the shuttle car located on the track 9 to enter the elevator car 8 along the track 9 for lifting and changing floors.

[0066] For example, when the pressure contact 411 changes from being pressed down to not being pressed, it is determined that the elevator car 8 is not stopped at the current track level. Under the elastic reset action of the limit elastic device 412, the pressure contact 411 rotates upward around the rotation axis 413. At this time, the rack 22 drives the blocking member 3 to make a linear motion extending beyond the base 1, thereby restoring the obstruction to the shuttle car. This prevents the shuttle car from falling to the ground due to signal errors before the elevator car 8 arrives, improving the operational stability and safety of the shuttle car.

[0067] Based on the above structural design, the meshing transmission of the elastic rotary transmission component 4 and the second transmission gear 21, and the meshing transmission of the second transmission gear 21 and the rack 22, convert the lifting motion of the car 8 into the horizontal linear motion of the blocking member 3. By simplifying the structure of the shuttle car blocking device, the operational stability of the shuttle car blocking device can be further improved, and the maintenance cost of the shuttle car blocking device can be reduced.

[0068] In one or more embodiments, both the first transmission gear 42 and the second transmission gear 21 can be made of steel, and their wear resistance can be improved by surface carburizing treatment. For example, the first transmission gear 42 has a module of 2, 30 teeth, a tooth tip height of 2.5 mm, and a tooth root height of 3.5 mm. Those skilled in the art can determine the specifications of the first transmission gear 42 based on the rotation angle of the pressure contact member 411 and the required extension length of the blocking member 3, and no further limitations are imposed here. In one example, the gear and the blocking member 3 can be connected by welding or integral molding.

[0069] In one or more embodiments of the invention, reference is made to Figure 2 As shown, the first transmission gear 42 is connected to the pressure contact member 411 in a transmission connection. The first transmission gear 42 meshes with the second transmission gear 21, and the central axis of the first transmission gear 42 is perpendicular to the central axis of the second transmission gear 21.

[0070] In this embodiment of the invention, the central axis of the first transmission gear 42 is perpendicular to the central axis of the second transmission gear 21. This means that through the meshing of the second transmission gear 21 with the first transmission gear 42, the driving rotational force of the second transmission gear 21 can be converted by 90 degrees before being output. Correspondingly, both the first transmission gear 42 and the second transmission gear 21 are provided with helical teeth. Specifically, the direction of the helical teeth on the first transmission gear 42 is angular to its central axis, and the direction of the helical teeth on the second transmission gear 21 is angular to its central axis. Therefore, a simple and efficient meshing transmission can be used to convert the lifting motion of the car 8 into the horizontal linear motion of the blocking member 3. For example, the transmission efficiency can be as high as 95% or more, and the helical tooth meshing can reduce the operating noise of the shuttle blocking device.

[0071] In one or more embodiments of the invention, reference is made to Figure 1 , Figure 2 as well as Figure 3 As shown, the shuttle blocking device may further include a slide rail 5 and a slider 6, wherein the length direction of the slide rail 5 is parallel to the extension and retraction direction of the blocking member 3. The rack 22 and the base 1 are slidably connected via the slide rail 5 and the slider 6. And / or, the blocking member 3 and the base 1 are slidably connected via the slide rail 5 and the slider 6.

[0072] In this embodiment of the invention, the sliding engagement of the slide rail 5 and the slider 6, with the length direction of the slide rail 5 parallel to the extension and retraction direction of the blocking member 3, can reduce the resistance of the rack 22 reciprocating linear motion along the base 1 and limit the sliding trajectory of the blocking member 3. This improves the transmission efficiency of the driving force and reduces the transmission loss of the driving force.

[0073] In one embodiment, if the number of slide rails 5 is one, the slide rail 5 can be installed on any of the following devices: the rack 22, the blocking member 3, and the base 1. The slider 6 is assembled according to the installation position of the slide rail 5, thereby realizing a sliding connection between the rack 22 and the base 1. Alternatively, a sliding connection can be realized between the blocking member 3 and the base 1.

[0074] In another embodiment, if at least two slide rails 5 are provided, the at least two slide rails 5 can be respectively installed on any two of the following devices: the rack 22, the blocking member 3, and the base 1. The slider 6 can be assembled according to the installation position of the slide rails 5, thereby realizing the sliding connection between the rack 22 and the base 1, and the sliding connection between the blocking member 3 and the base 1.

[0075] In one optional embodiment, the blocking telescopic assembly 2 may include a planetary reducer and a rack 22. The planetary reducer is connected to the elastic rotary transmission assembly 4 and is mounted on the base 1. For example, the sun gear of the planetary reducer meshes with the first transmission gear 42, thereby transmitting the rotational driving force output by the first transmission gear 42 to the rack 22 meshing with the planetary reducer.

[0076] The rack 22 is fixedly connected to the blocking member 3. When the planetary reducer rotates, it drives the rack 22 to move linearly along the radial direction of the planetary reducer, thereby driving the blocking member 3, which is fixedly connected to the rack 22, to extend out of the base 1 or retract into the base 1 in a linear motion. For example, when the pressure contact member 411 is pressed down by the elevator car 8, the limiting elastic member 412 is compressed, and when the pressure contact member 411 rotates downward around the rotating shaft 413, the rack 22 drives the blocking member 3 to retract into the base 1 in a linear motion, thereby removing the obstruction to the shuttle car, allowing the shuttle car located on the track 9 to enter the elevator car 8 along the track 9 for lifting and changing floors.

[0077] For example, when the pressure contact 411 changes from being pressed down to not being pressed, it is determined that the elevator car 8 is not stopped at the current track level. Under the elastic reset action of the limit elastic device 412, the pressure contact 411 rotates upward around the rotation axis 413. At this time, the rack 22 drives the blocking member 3 to make a linear motion extending beyond the base 1, thereby restoring the obstruction to the shuttle car. This prevents the shuttle car from falling to the ground due to signal errors before the elevator car 8 arrives, improving the operational stability and safety of the shuttle car.

[0078] Based on the above structural design, the meshing transmission of the elastic rotary transmission component 4 and the planetary reducer, and the meshing transmission of the planetary reducer and the rack 22, convert the lifting motion of the car 8 into the horizontal linear motion of the blocking member 3. The planetary reducer can improve power transmission efficiency and reduce the operating noise of the blocking device. This further improves the operational stability of the shuttle car blocking device and reduces its maintenance costs.

[0079] In one embodiment, the planetary reducer may further include at least two planetary gears meshing with the sun gear, a gear carrier, and a ring gear. The ring gear is distributed radially outward along the planetary gears and meshes with them. The gear carrier is rotatably connected to the central axis of all the planetary gears. The gear carrier is fixedly connected to the base 1, thereby allowing the ring gear to mesh with the rack 22. Helical teeth may be provided on the sun gear, enabling a 90-degree rotation switch from the first transmission gear 42 to the sun gear. Under the speed reduction and torque amplification effect of the planetary reducer, the driving efficiency of the blocking telescopic assembly 2 on the blocking member 3 can be improved, as can the service life of the blocking telescopic assembly 2.

[0080] In one or more embodiments of the invention, reference is made to Figure 1 and Figure 2 As shown, the base 1 may include a bottom 11, a first side 12, and a second side 13, with the bottom 11 contacting the surface of the track 9. The contact between the bottom 11 and the surface of the track 9 increases the contact area between the shuttle blocking device and the track 9, thereby improving the structural robustness of the shuttle blocking device.

[0081] The first side portion 12 and the second side portion 13 are arranged opposite each other along a third direction of the bottom 11, wherein the third direction is parallel to the length direction of the track 9, and the first side portion 12 and the second side portion 13 are respectively connected to the track 9. The bottom 11, the first side portion 12, and the second side portion 13 enclose an assembly space 101, in which the blocking telescopic component 2 and the elastic rotary transmission component 4 are located, wherein the elastic pressure contact unit 41 is rotatably connected to the first side portion 12. That is to say, the first side portion 12 and the second side portion 13 can provide an assembly area with the track 9. On the other hand, the first side portion 12 and the second side portion 13, in the third direction, can also provide double-sided protection for the blocking telescopic component 2 and the elastic rotary transmission component 4 located in the assembly space 101, thereby playing a role in dust and dirt prevention.

[0082] In one or more embodiments, the end faces of the first side portion 12 and the second side portion 13, which are opposite to each other, are each provided with two extending edges 15. The two extending edges 15 are distributed on both sides of the first side portion 12 along a first direction, and on both sides of the second side portion 13 along the first direction. Thus, when the shuttle car blocking device is installed on the track 9, it can contact the surface of the track 9 through the extending edges 15 along a third direction and be fixed with bolts. For example, the extending edges 15 are provided with mounting holes 1501 for bolts to pass through.

[0083] In one or more embodiments of the invention, reference is made to Figure 2 As shown, the base 1 may further include a connecting portion 14, which extends from the bottom 11 toward a direction away from the blocking telescopic assembly 2, and the limiting elastic member 412 is located between the connecting portion 14 and the pressure contact member 411.

[0084] In this embodiment of the invention, by extending the length of the connecting part 14 in the vertical direction, the overall volume of the base can be reduced while providing an installation area for the limiting elastic device 412 on the base. Furthermore, by reducing the included angle between the limiting elastic device 412 and the connecting part 14, the radial load on the limiting elastic device 412 after compression when the pressing member 411 is pressed down can be reduced, thereby improving the service life of the limiting elastic device 412.

[0085] In one or more embodiments, the connecting portion 14 is integrally formed with the bottom 11, the first side portion 12, and the second side portion 13. This integral structure design reduces the assembly process of the base and improves its production efficiency. The bottom 11, the first side portion 12, the second side portion 13, and the connecting portion 14 can be integrally formed from aluminum alloy or carbon steel. For example, the thickness of the bottom 11 can be 20 mm, thereby improving the structural strength and rigidity of the base. Another example is that the width of the base along the first direction is 100 mm, and its length along the third direction is 200 mm.

[0086] In one or more embodiments of the invention, reference is made to Figure 1 , Figure 3 as well as Figure 4 As shown, the shuttle blocking device may further include a cover 7, which cooperates with the base 1 to enclose the assembly space 101.

[0087] In this embodiment of the invention, the shape of the cover 7 can be adapted to the opening of the assembly space 101, thereby forming a closed enclosure of the assembly space 101 by matching the shape of the cover 7 with that of the base 1 without affecting the extension and retraction of the blocking member 3 and the vertical rotation of the pressing member 411. This provides dust protection for the meshing transmission devices in the blocking extension assembly 2 and the elastic rotary transmission assembly 4, preventing external impurities from entering the assembly space 101 and affecting transmission performance, improving the service life of the blocking extension assembly 2 and the elastic rotary transmission assembly 4, and further reducing structural maintenance costs.

[0088] In summary, this invention discloses a shuttle car blocking device. The device may include a base 1, a blocking telescopic assembly 2, a blocking member 3, and an elastic rotary transmission assembly 4. The base 1 is mounted on a track 9, the blocking telescopic assembly 2 is disposed on the base 1, and the blocking member 3 is tractively connected to the blocking telescopic assembly 2, allowing the blocking member 3 to extend and retract when the blocking telescopic assembly 2 is in operation. The device may include an elastic pressure contact unit 41 rotatably connected to the base 1 and a first transmission gear 42 tractively connected to the elastic pressure contact unit 41. The first transmission gear 42 meshes with the blocking telescopic assembly 2, and the elastic pressure contact unit 41 extends into the lifting area of ​​the elevator car. When the elastic pressure contact unit 41 is pressed down by the elevator car 8, the elastic pressure contact unit 41 rotates, causing the elastic rotary transmission assembly 4 to output a rotational driving force, driving the blocking member 3 to retract. Without external force, the elastic pressure contact unit 41 deforms and resets, driving the blocking member 3 to extend and block the shuttle car. Therefore, it can operate normally without any power source, improving the operational stability of the blocking device. Furthermore, the blocking component 3 automatically releases its obstruction of the shuttle car when the hoist car 8 reaches the corresponding track level. This allows for precise blocking of the shuttle car during its travel on multiple tracks 9, preventing it from falling to the ground due to signal errors before the hoist car 8 arrives, thus improving the shuttle car's operational stability and safety.

[0089] Reference Figure 3 and Figure 4As shown, this invention also discloses a material transport system, which may include a shuttle blocking device and a hoist as described in any of the above embodiments. The hoist includes a car 8 for transporting shuttles to different floors. The elastic pressure contact unit 41 extends into the car lifting area of ​​the hoist. When the elastic pressure contact unit 41 is pressed down by the car 8 of the hoist, the elastic pressure contact unit 41 rotates, driving the elastic rotary transmission assembly 4 to output a rotational driving force, which drives the blocking member 3 to retract. Without external force, the elastic pressure contact unit 41 deforms and resets, driving the blocking member 3 to extend and block the shuttle.

[0090] In this embodiment of the invention, the base 1 is mounted on the track 9 to provide structural support for other components of the shuttle blocking device. The blocking telescopic assembly 2 is disposed on the base 1, and the blocking member 3 is tractively connected to the blocking telescopic assembly 2 so that when the blocking telescopic assembly 2 is working, it drives the blocking member 3 to perform telescopic movement. In one example, when the blocking telescopic assembly 2 moves along a first direction, it can drive the blocking member 3 to extend beyond the base 1, and when the blocking telescopic assembly 2 moves along a second direction, it can drive the blocking member 3 to retract back onto the base 1. When the blocking member 3 is in the extended state, it extends into the operating area of ​​the shuttle in the track 9, thereby preventing the shuttle from continuing to move.

[0091] The elastic rotary transmission assembly 4 is disposed on the base 1 and is drively connected to the blocking telescopic assembly 2 to input a rotary driving force to the blocking telescopic assembly 2. The elastic rotary transmission assembly 4 includes at least an elastic pressure contact unit 41 rotatably connected to the base 1, and the elastic pressure contact unit 41 extends into the lifting area of ​​the hoist's car. The hoist's car 8 is used for changing levels of the shuttle car. When the shuttle car needs to change levels, the hoist's car 8 descends to the track level where the shuttle car is located. Then, the shuttle car corresponding to the track level enters the car 8 along the track 9. The car 8 then descends or ascends to transfer the shuttle car to the corresponding track level.

[0092] The elastic pressure contact unit 41 extends into the lifting area of ​​the elevator car, so that when the elevator car 8 reaches the track level corresponding to the shuttle car to be changed, the elastic pressure contact unit 41 can be pressed down by the car 8, thereby driving the shuttle car blocking device to operate by external power.

[0093] In one example, when the elastic pressure contact unit 41 is pressed down by the elevator car 8, the elastic pressure contact unit 41 rotates and serves as the power input terminal of the elastic rotary transmission assembly 4, inputting rotary driving force and outputting rotary driving force through the first transmission gear 42. The blocking telescopic assembly 2, which is driven by the first transmission gear 42, drives the blocking member 3, which is driven by it, to retract under the rotational driving force. When the blocking member 3 is in the retracted state, it is not in the shuttle car's operating area, thus releasing the obstruction to the shuttle car. Therefore, when the elevator car 8 reaches the track level corresponding to the shuttle car, the shuttle car blocking device immediately releases the obstruction to the shuttle car. This allows the shuttle car waiting to change floors to enter the elevator car 8 for floor changing.

[0094] In another example, when the car 8 is raised or lowered and the pressure on the elastic pressure unit 41 is removed, the elastic pressure unit 41 deforms and resets without external force, that is, the elastic pressure unit 41 rotates in the opposite direction, driving the blocking member 3 to extend along the base 1. When the blocking member 3 is in the extended state, it can continue to block the shuttle.

[0095] In summary, the shuttle car blocking device can operate normally without any power source of its own, thus improving the operational stability of the blocking device. Utilizing the lifting kinetic energy of the car 8, energy conservation can be achieved. Furthermore, the blocking component 3 automatically releases its obstruction of the shuttle car when the elevator car 8 reaches the corresponding track level. Precise control of blocking or releasing the shuttle car can be achieved without the need for detection sensors on the car 8.

[0096] In addition, when the shuttle car reaches the track level corresponding to the floor to be changed via the car 8, it can avoid the shuttle car falling to the ground due to signal error before the elevator car 8 arrives, thus improving the operation stability and safety of the shuttle car.

[0097] In one or more embodiments of the invention, reference is made to Figure 4 As shown, the hoist may further include an abutment member 81, which is disposed in the bottom 11 area of ​​the car 8 and near the shuttle blocking device. The abutment member 81 is used to abut against the elastic pressure contact unit 41 and drive the elastic pressure contact unit 41 to rotate.

[0098] In this embodiment of the invention, the installation position of the abutment member 81 in the bottom 11 region of the car 8 can be determined based on the required descent height when the blocking member 3 is fully retracted under the control of the elastic pressure contact unit 41. That is, when the car 8 is about to reach the track level where the shuttle car of the next floor is located, the abutment member 81 abuts against the elastic pressure contact unit 41 beforehand, and the elastic pressure contact unit 41 drives the blocking member 3 to retract. When the car 8 stops at the track level where the shuttle car of the next floor is located, the abutment member 81 maintains contact with the elastic pressure contact unit 41, causing the elastic pressure contact unit 41 to rotate at a certain angle. At this time, the blocking member 3 is in a retracted state. The shuttle car enters the car 8. When the car 8 rises, the abutment member 81 releases its contact with the elastic pressure contact unit 41, and under the elastic reset action of the elastic pressure contact unit 41, the blocking member 3 extends to continue blocking the shuttle car.

[0099] As the car 8 descends, the abutment member 81 continues to abut against the elastic pressure contact unit 41, causing the elastic pressure contact unit 41 to continue pressing down and rotating. After pressing down to a certain height, the elastic pressure contact unit 41 continues to rotate at a certain angle and then disengages from the abutment member 81. The abutment member 81 then releases its contact with the elastic pressure contact unit 41. Under the elastic reset action of the elastic pressure contact unit 41, the blocking member 3 extends to continue blocking the shuttle. For example, the time from when the car 8 begins to descend to when the blocking member 3 continues to block the shuttle can be equal to or less than 0.5 seconds.

[0100] In this invention, the material transport system further includes a track 9, on which a groove is provided for assembling the shuttle blocking device.

[0101] In summary, this invention discloses a material transport system, which may include a base 1, a telescopic blocking assembly 2, a blocking member 3, and an elastic rotary transmission assembly 4. The base 1 is mounted on a track 9, the telescopic blocking assembly 2 is disposed on the base 1, and the blocking member 3 is tractively connected to the telescopic blocking assembly 2 so that when the telescopic blocking assembly 2 is working, it drives the blocking member 3 to telescopically extend. The elastic rotary transmission assembly 4 may include an elastic pressure contact unit 41 rotatably connected to the base 1, and a first transmission gear 42 tractively connected to the elastic pressure contact unit 41. The first transmission gear 42 meshes with the telescopic blocking assembly 2, and the elastic pressure contact unit 41 extends into the lifting area of ​​the elevator car. When the elastic pressure contact unit 41 is pressed down by the elevator car 8, the elastic pressure contact unit 41 rotates, causing the elastic rotary transmission assembly 4 to output a rotational driving force, driving the blocking member 3 to retract. Under no external force, the elastic pressure contact unit 41 deforms and resets, driving the blocking member 3 to extend and block the shuttle car. Therefore, it can operate normally without any power source, improving the operational stability of the blocking device. Furthermore, the blocking component 3 automatically releases its obstruction of the shuttle car when the hoist car 8 reaches the corresponding track level. This allows for precise blocking of the shuttle car during its travel on multiple tracks 9, preventing it from falling to the ground due to signal errors before the hoist car 8 arrives, thus improving the shuttle car's operational stability and safety.
