Description

Technical Field

[0001] This application relates to the field of intelligent warehousing equipment technology, and in particular to a rescue tool for a four-way shuttle vehicle. Background Technology

[0002] In automated warehouses, four-way shuttles run on the tracks of each rack level to move goods and enable storage or retrieval. However, due to issues such as wheel deflection and jamming of the lifting mechanism during operation, it is often necessary to rescue and maintain malfunctioning four-way shuttles in the automated warehouse.

[0003] A common type of rescue tooling in the market typically consists of four studs and a crossbeam. The studs are supported on a track surface; rotating the studs, using the threaded holes in the trolley or crossbeam, lifts the empty trolley upwards until it is derailed. However, this structure often makes it difficult to rescue a trolley carrying cargo when it malfunctions. Other types of rescue tooling often require a four-way shuttle to autonomously reach a specific location within the automated warehouse, or require the coordinated operation of multiple sets of tooling to carry out the rescue. Existing automated warehouses do not allow for direct rescue at any location within the malfunction area. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a rescue tooling for a four-way shuttle. This application uses outrigger assemblies to fix an adjustable crossbeam and a support crossbeam to the track of the automated warehouse where the four-way shuttle operates. By adjusting the crossbeam and support crossbeam to support the pallet, the pallet is lifted to a height sufficient to detach from the four-way shuttle, facilitating the shuttle's evacuation from the fault location along the track.

[0005] To achieve the above objectives, the rescue tooling for the four-way shuttle provided in this application includes: an adjustable outrigger assembly detachably connected to the beam structure of the automated storage and retrieval system, having a support connector perpendicular to the beam structure; an adjusting beam detachably connected to the support connector of the adjustable outrigger assembly, wherein the adjusting beam is positioned perpendicular to the beam structure where the adjustable outrigger assembly is located; and a support beam detachably connected to the adjusting beam, wherein the support beam is positioned perpendicular to the adjusting beam and simultaneously parallel to the beam structure where the adjustable outrigger assembly is located.

[0010] Optionally, in the rescue tooling of the four-way shuttle vehicle as described above, the outrigger adjustment hole structure on one side of the adjusting beam is configured as a through hole that matches the outer diameter of the stud, and the outrigger adjustment hole structure on the other side is configured as a long groove-shaped structure extending along the axial direction of the adjusting beam; the adjusting nut abuts against the upper and lower sides of the through hole and the long groove-shaped structure respectively.

[0011] Optionally, in the rescue tooling of the four-way shuttle vehicle as described above, the adjustable outrigger assembly is further provided with a C-clamp that matches the size of the crossbeam. The C-clamp is also provided with a pressure plate on one side of its opening and a knob screw on the other side of its opening. The end of the pressure plate is provided with a bending structure toward the center of the opening of the C-clamp. In the connected state, the bending structure, the inner wall of the opening of the C-clamp, and the inner end of the knob screw are respectively abutted and fixed to the outer peripheral surface of the crossbeam structure.

[0012] Optionally, in the rescue equipment of the four-way shuttle vehicle as described above, the supporting crossbeam and the adjusting crossbeam are detachably connected by a quick-clamp connector; the bottom of the quick-clamp connector is fixed to the lower surface of the adjusting crossbeam, and the middle part of the quick-clamp connector is connected to the supporting crossbeam; the lower surface of the supporting crossbeam and the bottom of the quick-clamp connector are respectively clamped to the upper and lower sides of the adjusting crossbeam.

[0013] Optionally, in the rescue tooling of the four-way shuttle vehicle as described above, the quick-clamp connector includes: a hollow connecting groove with an inner diameter not less than the outer wall size of the supporting crossbeam; a pressure plate knob located at the upper part of the hollow connecting groove, passing through the top of the hollow connecting groove and abutting against the upper surface of the supporting crossbeam; a stiffening plate extending downward from the hollow connecting groove and bending at the bottom towards the opening direction of the hollow connecting groove; in the connected state, the lower surface of the supporting crossbeam abuts against the bottom surface of the hollow connecting groove and extends outward from the opening direction of the hollow connecting groove, the lower surface of the adjusting crossbeam abuts against the bent surface at the bottom of the stiffening plate, and the upper surface of the adjusting crossbeam abuts against the lower surface of the adjusting crossbeam outside the hollow connecting groove.

[0014] Optionally, in the rescue tooling of the four-way shuttle as described above, the adjustable outrigger assembly is installed on the bracket beam and the main rail beam near the fault location; the adjusting beam is moved along the support connector according to the height of the cargo pallet and fixed at the corresponding height position; the support beam is fixed on the adjusting beam through the quick-clamp connector, independently supporting the cargo pallet to lift upward, or cooperating with the top surface of the sub-rail structure to maintain the cargo pallet at the height position away from the faulty four-way shuttle.

[0015] Compared with existing solutions, this application has the following technical advantages: The rescue tooling for a four-way shuttle provided in this application includes: an adjustable support leg assembly that can be fixed to the beam structure of an automated warehouse, and an adjustable crossbeam mounted on the adjustable support leg assembly, with a support crossbeam connected to the adjustable crossbeam. This application utilizes the adjustment crossbeam, which moves up and down along the adjustable support leg assembly, to lift and support the pallet at the fault location by inserting the support crossbeam into the pallet at the fault location, allowing the four-way shuttle to evacuate along the track from the fault location. This application satisfies the requirement for quick tooling setup by personnel while ensuring that the crossbeam does not shift horizontally during height adjustment. The installation structure of this application effectively restricts the rotational freedom of the crossbeam, preventing tipping during support, and solves the problem of limited positioning in existing rescue tooling on the market, greatly enhancing compatibility and stability. The rescue tooling of this application allows for quick operation by personnel without the need for additional tools, and enables a more secure connection of the crossbeam, ensuring the safety of the goods and the four-way shuttle.

[0016] Specifically, the cargo truck separation and rescue tooling for a four-way shuttle vehicle provided in this application mainly includes: adjustable outriggers with quick-clamp function, and support beams and adjustable beams that can be assembled and combined into a grid-shaped stable structure. This application modularizes the support frames on both sides of the grid-shaped stable structure, allowing for pre-assembly of the two outriggers and beams while still enabling rapid adjustment. This satisfies the function of cargo truck separation when the trolley fails at various positions on the subrail or main rail. The tooling height can be flexibly adjusted via the studs on the four adjustable outriggers. In conjunction with this frame structure, this application provides a fixed outrigger position at the adjustable beam of the gantry and a movable outrigger position at another location. This allows for quick setup of the tooling while ensuring that the beam does not shift horizontally during height adjustment. The rotational freedom between the support beam and the adjustable beam is restricted by quick-clamp connectors, preventing tipping during support and solving the problem of limited positioning in existing rescue tooling on the market, greatly enhancing compatibility and stability. The rescue tooling of this application features a quick-clamping pressure plate section at each of its connecting parts. The contact surface between the pressure plate and the knob lever is designed as an inclined plane, thereby increasing the contact area and support strength. Furthermore, this application uses injection-molded material for the lever handle, facilitating quick operation without requiring additional tools. In a more preferred embodiment, this application may also incorporate textured surfaces and anti-slip pads on the bottom of the pressure plate to increase friction, thus making the beam connection more secure.

[0017] Other features and advantages of this application will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing this application. Attached Figure Description

[0025] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0026] The terms "inner" and "outer" as used in this application refer to directions pointing inward from the orbital system itself as "inner" and "outward" as "outward"; rather than being a specific limitation on the device mechanism of this application.

[0027] The terms "left" and "right" as used in this application refer to the user's left side as the left and the user's right side as the right when the user is facing the direction of travel of the four-way shuttle, and do not constitute a specific limitation on the device mechanism of this application.

[0028] The term "connection" as used in this application can mean a direct connection between components or an indirect connection between components through other components.

[0029] The terms "up" and "down" as used in this application refer to the direction from the track system to the top of the cargo carried by the four-way shuttle when the user is facing the direction of travel of the four-way shuttle, which is up, and vice versa, which is down, and are not a specific limitation on the device mechanism of this application.

[0030] Shuttle car malfunctions are generally categorized into two types: driving malfunction causing jamming and lifting malfunction causing jamming. The probability of both malfunctioning simultaneously is extremely low. Driving or lifting malfunctions can be categorized as follows: ① Driving malfunction occurs when the trolley is traveling on the main rail and in the reversing position, but lifting can operate normally; ② Driving malfunction occurs when the trolley is traveling on the main rail and in any position other than the reversing position, but lifting can operate normally; ③ Lifting malfunction occurs when the trolley is traveling on the main rail and in the reversing position, but driving can operate normally; ④ Driving malfunction occurs when the trolley is traveling on the sub-rail and in the picking position, but lifting can operate normally; ⑤ Driving malfunction occurs when the trolley is traveling on the sub-rail and in any position other than the picking position, but lifting can operate normally; ⑥ Lifting malfunction occurs when the trolley is traveling on the sub-rail, but driving can operate normally.

[0031] To address the aforementioned malfunctions, this application provides a truck separation and rescue tool for a four-way shuttle operating in a multi-level parking garage, comprising: Adjustable support leg assembly 1, which is detachably connected to the beam structure of the automated rack, has a support connector perpendicular to the beam structure; The adjusting beam 4 is detachably connected to the support connector of the adjustable leg assembly 1, and the setting direction of the adjusting beam 4 is perpendicular to the beam structure where the adjustable leg assembly 1 is located. A support beam 5 is detachably connected to an adjustable beam 4. The direction of the support beam 5 is perpendicular to the adjustable beam 4 and parallel to the beam structure where the adjustable support leg assembly 1 is located. During assembly, the support beam 5 is inserted into the pallet of the faulty position in the three-dimensional rack, and the pallet of the faulty position is lifted and supported accordingly by adjusting the movement of the beam 4 along the support connector.

[0032] This structure allows for rapid assembly through its modular design. It is highly versatile and can quickly facilitate truck separation and rescue in complex automated warehouse environments. By adjusting the support structure of the tooling legs and the crossbeam connection structure, this application allows for truck separation with only one set of tooling.

[0033] Specific reference Figure 1 as well as Figure 12As shown, since goods are usually placed on the sub-tracks of the automated racking system, in this application, the adjustable support leg assembly 1 is generally installed on the nearby bracket beam and main rail beam according to the location of the four-way shuttle's malfunction. During the evacuation process, the four-way shuttle at the malfunctioning location is first pulled to the top of the main rail, and then driven to evacuate from the main rail. In specific installation, the adjustable support leg assembly 1 closest to the evacuation direction of the four-way shuttle is generally installed on the bracket beam, and the adjustable support leg assembly 1 on the other side is installed on the main rail beam. Thus, the adjustable support leg assembly and other installation components will not obstruct the evacuation path of the four-way shuttle, ensuring its stable support of goods.

[0034] The bottom of the adjustable support leg assembly 1 can be equipped with a C-shaped clamp with a size not smaller than that of the crossbeam, and a stud 10 is installed on the C-shaped clamp as a support connector. Specifically, the C-shaped clamp can have a pressure plate 11 on one side of its opening and a knob screw 12 on the other side of its opening. The end of the pressure plate has a bent structure facing the center of the C-shaped clamp opening. The four sets of adjustable support legs are fixed to the cantilever crossbeam or main rail crossbeam of the shelf by quick insertion of the C-shaped clamp and pressing of the pressure plate, and the support position can be adjusted along the side of the rail. In the connected state, the bent structure, the inner wall of the opening of the C-shaped clamp, and the inner end of the knob screw are respectively abutted and fixed to the outer peripheral surface of the crossbeam structure. The quick insertion of the C-shaped clamp is compatible with guide rail profiles of different heights and widths currently on the market. The C-type quick-connect clamp has a high-strength stud welded on top, and a rubber-handled hand-tightening pressure plate knob is set on the bottom and side. The knob screw has a conical cross-section structure that fits against the inclined surface of the pressure plate, which can increase the contact area and force. The support legs are aligned with the back of the track and can be adjusted to any position along this surface.

[0035] Then, this application provides support leg adjustment hole structures at both ends of the adjusting beam 4, and uses the stud to pass through the support leg adjustment hole structure to connect a pair of adjusting nuts 2 on the upper and lower sides of the adjusting beam 4 respectively. By screwing the adjusting nuts 2 up and down along the stud to different height positions, the setting height of the adjusting beam 4 is limited.

[0036] In a specific configuration, the leg adjustment hole structure on one side of the adjusting beam 4 can be configured as a through hole matching the outer diameter of the stud, while the leg adjustment hole structure on the other side can be configured as a long groove-shaped structure extending axially along the adjusting beam 4. The adjusting nuts 2 abut against the upper and lower sides of the through hole and the long groove-shaped structure, respectively. Due to the presence of the adjusting nuts on the upper and lower sides, the legs can slide freely within the long groove, and each nut adjustment side has a washer to increase the force-bearing surface.

[0037] The support beam 5 and the adjusting beam 4 can be connected by means of... Figure 9The quick-clamp connector 3 shown is detachable. The quick-clamp connector 3 is integrally welded from profile, stiffener, and pressure plate: the bottom of the quick-clamp connector 3 abuts and is fixed to the lower bottom surface of the adjusting crossbeam 4, and the middle part of the quick-clamp connector 3 is connected to the supporting crossbeam 5; the lower bottom surface of the supporting crossbeam 5 and the bottom of the quick-clamp connector 3 are respectively clamped to the upper and lower sides of the adjusting crossbeam 4. Thus, the quick-clamp connector 3 can use a profile with an inner diameter not less than the outer wall size of the supporting crossbeam 5 as a hollow connecting groove 31 to fit the supporting crossbeam on its upper part. At the same time, using the pressure plate knob 32 set on the upper part of the hollow connecting groove 31, it is inserted through the top of the hollow connecting groove 31 and abuts against the upper surface of the supporting crossbeam 5, and the supporting crossbeam (5) is quickly inserted through the inner side of the profile. After insertion, it is manually tightened by the upper pressure plate knob, so that the adjusting crossbeam (4) and the supporting crossbeam (5) are tightly connected. The rib 33 of the quick-clamp connector 3 extends downward from the hollow connecting groove 31 and bends at the bottom towards the opening of the hollow connecting groove 31 to form another C-shaped clamp, thereby fixing the adjusting beam 4 and the supporting beam 5 together by top pressure. This ensures that the lower surface of the supporting beam 5 can tightly abut against the bottom surface of the hollow connecting groove 31 in the connected state, allowing it to extend only outward from the opening of the hollow connecting groove 31, thus limiting the adjustment beam 4 using the lower bottom surface structure of the supporting beam 5. The lower surface of the adjusting beam abuts against the bent surface at the bottom of the rib 33, and the upper surface of the adjusting beam 4 abuts against the lower surface of the adjusting beam 4 outside the hollow connecting groove 31, effectively preventing mutual deflection between the beam structures, thereby further improving the stability of palletized cargo support.

[0038] Therefore, this application installs the adjustable outrigger assembly 1 on the bracket beam and the main rail beam near the fault location; The adjusting beam 4 is installed on the adjustable support leg assembly 1. By rotating the adjusting nut 2 up and down, the beam 4 is moved and adjusted along the support connector according to the height of the pallet, and finally fixed at a position close to the height of the pallet. The adjusting beam 4 generally has two installation positions for the adjustable support leg assembly 1. One of them has a small through hole that can only be adjusted up and down, while the other side has a long groove structure that provides a certain amount of adjustment space to adapt to different installation needs, allowing the adjustable support leg assembly 1 to be adjusted left and right, so that it can be inserted into the rack guide rail during installation.

[0039] The support beam 5 is tightly fixed to the adjusting beam 4 by the quick-clamp connector 3, independently supporting the upward lifting of the cargo pallet, or working with the top surface of the sub-rail structure to maintain the cargo pallet at the height position away from the malfunctioning four-way shuttle.

[0040] The two crossbeams are of different lengths, set according to the span of the main rail and the cantilever span of the rack. After the rescue tool supports the pallet, the adjustable crossbeams will be slightly higher than the trolley to allow subsequent vehicles to be safely towed away or driven. After the crossbeams are assembled, they can form a stable grid-like structure to support the goods.

[0041] Therefore, referring to Figure 2 The diagram shows the structure of the first embodiment of the rescue tool of this application. It can solve the following problems: ① the trolley malfunctions when traveling on the main rail surface and in the reversing position, but the lifting operation is normal; ③ the trolley malfunctions when traveling on the main rail surface and in the reversing position, but the travel operation is normal. In specific operations, the adjustable support leg assembly 1, adjusting nut 2, and adjusting beam 4 can be prefabricated into two sets of gantry support legs. One set of gantry support legs is installed on the main rail beam, and the other set is installed on the corbel beam. By rotating the adjusting nut 2, the adjusting beam 4 is quickly raised to the approximate height of the pallet fork position. Then, the supporting beam 5 is inserted into the pallet fork position, with the insertion direction of the supporting beam 5 consistent with the direction of the main rail. Next, the quick-clamp connector 3 tightly connects the adjusting beam 4 and the supporting beam 5 together. Finally, by rotating the adjusting nut 2 with a wrench or tool, the adjusting beam 4 and the supporting beam 5 are slowly raised until the supporting beam 5 is in close contact with the pallet surface, until the pallet and shuttle are separated to a certain safe distance. At this point, the rescue tool installation is complete. If a vehicle malfunctions, personnel use tools to create a safe distance from the current rescue equipment. After the trolley leaves the pallet position, it is lifted off the track by at least one vehicle height using a hoist to ensure the safe movement of the rescue vehicle. A shuttle car that is operating normally is then dispatched to remove the malfunctioning vehicle. If the lifting mechanism malfunctions but the vehicle is operating normally, the system controls the trolley to move away. Upon returning to the pallet position, personnel use a wrench or tools to slowly lower the adjusting beam 4 and the supporting beam 5 by turning the adjusting nut 2 until the pallet is completely placed on the top plate of the shuttle car. Personnel then manually loosen the quick clamp connector 3 and the pressure plate of the adjustable outrigger assembly 1 using the knob. The supporting beam 5 and the two sets of gantry outriggers are then removed one by one. After the passage is cleaned, the shuttle car resumes normal operation of the goods.

[0042] Figure 3 This is a schematic diagram of the second implementation method of the rescue tool, mainly addressing the fault where the trolley malfunctions while traveling on the main rail surface in a non-reversing position, but the lifting operation can continue normally. Because the adjustable outrigger assembly 1 is designed with a C-shaped quick-clamp structure, it can freely slide and adjust along any position on the side of the crossbeam, thus adapting to any position of the trolley when it malfunctions on the main rail surface. The rescue method and instructions are the same as described above. Figure 1 The methods are basically the same, so I won't go into details.

[0043] Figure 4This is a schematic diagram of the third implementation method. This embodiment mainly addresses the malfunction in scenario ④, where the trolley malfunctions while traveling on the sub-rail surface at the picking position, but the lifting mechanism can still operate normally. When the shuttle is carrying goods, the trolley lifting plate can be lowered to the middle position first. Since the top surface of the sub-rail structure, which is perpendicular to the main rail beam in each shelf layer, is higher than the top surface of the main rail beam, the goods will fall onto the sub-rail shelf along with the pallet. At this point, personnel intervene to pull the malfunctioning trolley to the main rail aisle, and use a hoist to remove the malfunctioning trolley from the track to a safe height. After a normally operating shuttle is dispatched to remove the malfunctioning trolley, the warehousing system can return to normal operation.

[0044] Figure 5 This is a structural diagram of the fourth implementation of the rescue tool, addressing the following fault scenario: ⑤ The trolley malfunctions while traveling on the sub-rail surface, failing at any position other than the pickup location, but the lifting mechanism can still operate normally. In this case, the adjustable outrigger assembly 1, adjusting nut 2, and adjusting beam 4 can be prefabricated into two sets of gantry outriggers. One set is installed on the main rail beam, and the other set is installed on the bracket beam, with the bracket beam facing the direction the malfunctioning trolley will be towed away. By rotating the adjusting nut 2, the adjusting beam 4 is quickly adjusted to approximately the height required for the pallet fork to be in place. Then, the supporting beam 5 is inserted into the pallet fork position, with the insertion direction aligned with the main rail direction. Next, the quick-clamp connector 3 tightly connects the adjusting beam 4 and the supporting beam 5 together. Finally, by rotating the adjusting nut 2 with a wrench or tool, the supporting beam 5 is adjusted to a certain relative height to the sub-rail or shelf surface, with the supporting beam 5 approximately 14mm above the bottom of the pallet fork. At this point, the malfunctioning trolley's lifting plate descends to the middle position, and the pallet can be lowered. Once the malfunctioning vehicle is on the shelf and support beam 5, personnel intervene to tow it to the main rail reversing position. The malfunctioning vehicle then uses the lifting box to switch the main rail travel wheels onto the main rail surface. If the main rail travel of the malfunctioning vehicle is not damaged, the trolley is controlled to automatically drive away. If the main rail travel of the malfunctioning vehicle is damaged, personnel then tow the malfunctioning vehicle away from the tooling position. After the trolley leaves the pallet position, it is derailed from the track to a safe height by a hoist to allow the rescue vehicle to drive safely. The rescue vehicle is dispatched to first pull away the malfunctioning vehicle, and then the rescue vehicle returns to the pallet position and lifts the lifting box to a high position to lift the pallet. Personnel use manual knobs to loosen the quick clamp connector 3 and the pressure plate of the adjustable support leg assembly 1. Then, the support beam 5 and the two sets of gantry support legs are removed one after another. After the aisle is cleaned, the shuttle car resumes normal operation of the goods.

[0045] Figure 6 This is a structural diagram of the fifth implementation of the rescue tooling, primarily addressing the fault scenario ⑥ where the trolley is traveling on the sub-rail surface, experiencing a lifting failure, but can still operate normally. In this case, the faulty trolley can first be moved to the main rail reversing position, and then the rescue tooling can be installed, using the same installation method as described above. Figure 5The implementation instructions are basically the same. After installation, the support beam 5 is lifted by turning the adjusting nut 2 with a wrench or tool to separate it from the malfunctioning vehicle. After the malfunctioning vehicle is separated from the vehicle, it returns to the cargo retrieval position on the subrail. The dispatch rescue vehicle drives to the pallet position of the tooling, and the lifting plate of the rescue vehicle is raised to the high position. Personnel use a wrench or tool to turn the adjusting nut 2 slowly to lower the adjusting beam 4 and the support beam 5 until the pallet is completely placed on the top plate of the rescue vehicle. Finally, the tooling is removed, and the rescue vehicle drives away with the cargo. Then the malfunctioning vehicle drives to the reversing position, and personnel use a hoist to remove the malfunctioning vehicle from the track to a safe height. Finally, the rescue vehicle transports the malfunctioning vehicle away.

[0046] The advantages of this application are: The shuttle rescue tool provided in this application mainly solves the problem that it is often difficult to carry out rescue when the shuttle carrying goods malfunctions; or other types of tooling often require the shuttle to reach a specific location, or one set of tooling cannot achieve rescue at any location and multiple sets of tooling are required, which is too cumbersome.

[0047] This invention effectively reduces parts processing requirements, shortens component assembly time, and offers high versatility by reducing the number of parts. Its simple structure and bottom support legs can be flexibly fixed to any crossbeam of the shelf for easy and quick assembly and disassembly. When used in conjunction with a shuttle vehicle, it better serves the field of intelligent warehousing and logistics.
