Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, and in particular to a shuttle rescue device and a rescue vehicle. Background Technology

[0002] Currently, shuttle car rescue primarily relies on automatic uncoupling devices. A functioning shuttle car tows the disabled shuttle to the repair bay. While this method is helpful for two-way shuttle cars, it's not entirely suitable for four-way shuttle cars. To improve the versatility of the rescue structure, existing technology has developed a new type of shuttle car rescue equipment (a typical structure is referenced in the existing patent "A Rescue Device and Method for Four-Way Shuttle Cars," application number 202411324834.8). This type of equipment modifies a functioning shuttle car into a rescue shuttle car equipped with a lifting device. The rescue shuttle car then lifts the disabled shuttle car onto another functioning shuttle car, which then transports the disabled shuttle car to the repair bay for rescue.

[0003] However, existing shuttle rescue equipment has the following problems: Because it relies on the boom of the rescue shuttle for transportation, the boom length is often greater than the side length of the rescue shuttle in order to lift the disabled vehicle. Whether it is a long boom structure or the need for an additional shuttle that is in normal operation to carry the goods, sufficient space needs to be reserved in the parent-child passage. An excessively large parent-child passage limits the number of storage locations in the warehouse and reduces the storage capacity of the warehouse. Utility Model Content

[0004] The purpose of this invention is to provide a shuttle rescue device and a rescue vehicle to alleviate the aforementioned technical problems in the prior art.

[0005] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions: In a first aspect, this utility model provides a shuttle vehicle rescue device, comprising: The base has a fixing part that can be fixed to a walking vehicle; A tilting frame, located on one side of the base, has a fixing part two that can be fixed to the shuttle car; The linkage mechanism includes multiple hinge points, some of which are hinged to the base and some of which are hinged to the tilting frame; A flipping mechanism is installed on the base and is connected to the linkage mechanism for driving the linkage mechanism to flip the flipping frame.

At least one of the linkage rod groups has a side rod fixed or integrally connected to a hinge rod near the base. The side rod has a limiting recess, which is a limiting groove or a limiting hole. A limiting component is fixed on the output part of the horizontal push-pull assembly.

[0010] In an optional embodiment, the shuttle rescue device further includes a limiting component, which includes a limiting pin and a limiting bracket disposed on the base facing the tilting frame and extending upward. The limiting bracket is provided with a first mounting hole, and the flip frame is provided with a second mounting hole on the side near the base. When the flip frame is in the first position, the limiting pin passes through the first mounting hole and the second mounting hole to fix the flip frame to the limiting bracket.

[0015] Specifically, in the present invention, the term "and / or" indicates that the structure before "and / or" and the structure after "and / or" are set simultaneously or selectively.

[0016] The embodiments of this utility model can achieve at least the following beneficial effects: The usage method of this embodiment is as follows: When a shuttle car malfunctions in a warehouse, the base of the shuttle car rescue device is fixed to the top of the walking vehicle through a fixing part to form a rescue vehicle. The walking vehicle can be a separately designed vehicle with wheels and a wheel drive mechanism, or it can be a vehicle formed by removing the lifting plate from a normally functioning shuttle car.

[0017] Position the tilting frame in the first position (folded above the base), and drive the assembled rescue vehicle to the side of the malfunctioning shuttle, with the tilting frame facing the malfunctioning shuttle. Workers approach this position from the safety passage.

[0028] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Firstly, this embodiment provides a shuttle vehicle rescue device, referring to... Figure 1 The shuttle rescue device includes a base 1, a tilting frame 2, a linkage mechanism, and a tilting mechanism 4. The base 1 has a fixing part that can be fixed to the traveling carrier 110. The tilting frame 2 is located on one side of the base 1 and has a fixing part that can be fixed to the shuttle. The linkage mechanism includes multiple hinge points, some of which are hinged to the base 1 and some to the tilting frame 2. The tilting mechanism 4 is mounted on the base 1 and is connected to the linkage mechanism for driving the linkage mechanism to tilt the tilting frame 2. The tilting frame 2 can be tilted in at least two positions: a first position and a second position. In the first position, the tilting frame 2 is folded above the base 1; in the second position, the tilting frame 2 is located on one side of the base 1 and extends horizontally.

[0030] Secondly, this embodiment also provides a rescue vehicle, referring to... Figures 2 to 5The rescue vehicle includes a walking vehicle 110 and the aforementioned shuttle rescue device. The base 1 of the aforementioned shuttle rescue device is fixed to the top of the walking vehicle 110 by a fixing part.

[0031] The shuttle rescue device provided in this embodiment is used in the same way as the rescue vehicle provided in the second aspect above. When a faulty shuttle 120 occurs in the warehouse, the base 1 of the shuttle rescue device is fixed to the top of the walking carrier 110 through the fixing part to form a rescue vehicle. The walking carrier 110 can be a carrier with a separately designed drive wheel and drive wheel mechanism, or it can be a carrier formed after the lifting plate of a normally operating shuttle is removed.

[0032] Reference Figure 2 and Figure 3 Position the tilting frame 2 in the first position (tilting frame 2 is folded above base 1), and drive the assembled rescue vehicle to a position next to the malfunctioning shuttle 120, with the tilting frame 2 facing the malfunctioning shuttle 120. Workers approach this position from the safety passage; then, refer to... Figure 4 and Figure 5 The flipping mechanism 4 drives the linkage mechanism to flip the flipping frame 2 to the second position, so that the flipping frame 2 is located on one side of the base 1 and extends horizontally, and is located above the fault shuttle 120; then, the fixing part 2 of the flipping frame 2 is fixed to the top of the frame of the fault shuttle 120; then refer to Figure 2 and Figure 3 The flipping mechanism 4 drives the linkage mechanism to flip the flipping frame 2 back to the first position, so that the faulty shuttle 120 is loaded onto the rescue vehicle; the rescue vehicle is then driven to carry the faulty shuttle 120 to the repair station for repair.

[0033] The shuttle rescue device and rescue vehicle provided in this embodiment can achieve at least the following beneficial effects: The rescue process of this shuttle rescue device is achieved by flipping, which eliminates the need for a long boom. During the movement of the rescue vehicle, the size of the flipping frame 2 is much smaller than the length of the boom in the prior art. Furthermore, no additional normally operating shuttle is required to carry the goods. The parent-child passage only needs to be able to allow the normal shuttle to pass through in an orderly manner. This reduces the width requirement of the parent-child passage, reduces the storage space occupied by the parent-child passage, and increases the storage capacity of the warehouse.

[0034] More specifically, the shuttle rescue device provided in the first aspect of this embodiment also has multiple optional implementation methods, and the corresponding design of the shuttle rescue device installed on the rescue vehicle provided in the second aspect is detailed below: Continue to refer to Figures 1 to 5In an optional embodiment of this example, the flipping mechanism 4 includes a horizontal push-pull assembly 41; the output of the horizontal push-pull assembly 41 is connected to one side of the linkage mechanism and is used to push and pull the linkage mechanism in the horizontal direction so that the linkage mechanism drives the flipping frame 2 to flip.

[0035] This optional embodiment uses a horizontal push-pull assembly 41 to drive the linkage mechanism, thereby causing the tilting frame 2 to tilt, avoiding the problems of uneven torque or uncontrollable motion trajectory caused by the traditional direct drive tilting frame 2, and improving the stability and predictability of the tilting process.

[0036] The horizontal push-pull assembly 41 can be a drive element assembly such as a pneumatic cylinder telescopic rod assembly or an electric cylinder telescopic rod assembly. Optionally, in some embodiments of this example, the flipping mechanism 4 further includes a worktable 42, a first support 43, and a second support 44. The worktable 42 is fixed on the base 1, and the first support 43 and the second support 44 are fixed to the worktable 42 at intervals along the push-pull direction of the horizontal push-pull assembly 41. The horizontal push-pull assembly 41 includes a lead screw 411, a ball screw nut 412 mounted on the lead screw 411, and a slider 413 fixedly connected to the ball screw nut 412. The two ends of the lead screw 411 are rotatably mounted on the first support 43 and the second support 44 respectively through bearings, and one end of the lead screw 411 protrudes from the corresponding support to form a rotary drive end 4111. The slider 413 is hinged to one side of the linkage mechanism. The rotary drive end 4111 of the lead screw 411 can be used with an electric wrench. During use, it is assembled by the operator to drive the lead screw 411 to rotate. Alternatively, a handle can be designed on the rotary drive end 4111, or a rotary motor can be connected to the drive to rotate.

[0037] In this optional embodiment, the combination of lead screw 411 and ball screw nut 412 can achieve high-precision linear motion, so that the horizontal push-pull assembly 41 has higher position control accuracy when pushing the linkage mechanism, ensuring the accuracy and consistency of the flipping action; the slider 413 is hinged to one side of the linkage mechanism. This connection method not only ensures the smooth flipping of the linkage mechanism, but also absorbs and buffers external impacts to a certain extent, improving the safety of operation.

[0038] In a further optional embodiment, the aforementioned horizontal push-pull assembly 41 further includes a horizontal slide rail 45 mounted on the worktable 42. The horizontal slide rail 45 extends along the push-pull direction of the horizontal push-pull assembly 41, and the slider 413 slides in cooperation with the horizontal slide rail 45. In this optional embodiment, the horizontal slide rail 45 provides a stable guide for the slider 413, ensuring its precise and smooth movement in the horizontal direction. This guiding effect reduces the offset and vibration of the slider 413 during movement, improving the motion accuracy and smoothness of the entire flipping mechanism 4.

[0039] Continue to refer to Figures 1 to 5In an optional embodiment of this example, the linkage mechanism includes at least one row of linkage rod groups 3, each row of linkage rod groups 3 including at least two inverted V-shaped hinge units arranged in sequence; each inverted V-shaped hinge unit is formed by two hinge rods 31 with one end hinged to each other, and the two hinge rods 31 with their opposite ends are respectively hinged to the base 1 and the flipping frame 2 through hinge seats; the two hinge rods 31 that are close to each other between each two adjacent inverted V-shaped hinge units are staggered and hinged through the hinge member 32, so that an "M" shape is formed between the hinge rods 31 of each two adjacent inverted V-shaped hinge units. At least one of the linkage rod groups 3 has a side rod 33 fixed or integrally connected to a hinge rod 31 near the base 1. The side rod 33 has a limiting recess 331, which is a limiting groove or a limiting hole. A limiting component 414 is fixed on the output part of the horizontal push-pull assembly 41. The limiting component 414 is limited inside the limiting recess 331 so that the horizontal push-pull assembly 41 can pull the side rod 33 to move back and forth in the horizontal direction. During the pulling process, the limiting component 414 moves inside the limiting recess 331.

[0040] In this optional embodiment, the linkage mechanism composed of multiple inverted V-shaped hinge units and the "M"-shaped structure they form ensures a reasonable distribution of the force transmission path. This design reduces unnecessary torque loss, improves energy transmission efficiency, and allows the power of the horizontal push-pull assembly 41 to be transmitted more effectively to the tilting frame 2. This makes the movement of the tilting frame 2 more stable and consistent during the tilting process. Furthermore, this multi-link structure can effectively distribute the load and reduce stress concentration at a single hinge point, thereby improving the smoothness of the overall movement. In addition, the cooperation between the limiting recess 331 and the limiting component 414 not only ensures the effective traction of the horizontal push-pull assembly 41 on the side rod 33 and each hinge rod 31, but also absorbs and buffers external impacts to a certain extent, improving operational safety. This design reduces the risk of accidental deviation or jamming, enhancing the reliability and safety of the system.

[0041] Preferably, but not limited to, the linkage mechanism includes two rows of linkage groups 3, which are respectively arranged on both sides of the flipping mechanism 4 to increase linkage stability.

[0042] Continue to refer to Figures 1 to 5 In an optional embodiment of this invention, the shuttle rescue device further includes a limiting component 6, which includes a limiting pin 62 and a limiting bracket 61 located on the side of the base 1 facing the tilting frame 2 and extending upward. The limiting bracket 61 is provided with a first mounting hole, and the tilting frame 2 is provided with a second mounting hole on the side near the base 1. When the tilting frame 2 is in the first position, the limiting pin 62 passes through the first mounting hole and the second mounting hole to fix the tilting frame 2 to the limiting bracket 61.

[0043] In this optional embodiment, the design of the limiting component 6 provides a reliable mechanical locking method, which enables the tilting frame 2 to be firmly fixed in the first position, ensuring load stability and safety when the rescue vehicle carries the fault shuttle 120.

[0044] In an optional embodiment of this invention, the shuttle rescue device further includes a support mechanism 5. The support mechanism 5 includes a horizontal telescopic component 51 and a support leg 52. The horizontal telescopic component 51 includes a fixed part and a telescopic part. The fixed part is fixed to the base 1, and the telescopic part can extend horizontally to one side of the base 1. The support leg 52 is installed in an adjustable manner at the portion of the telescopic part that extends to one side of the base 1. The methods for adjusting the height of the support leg 52 include, but are not limited to, providing a threaded hole on the telescopic part, providing external threads on the outside of the support leg 52, and adjusting the height by rotating the support leg 52 with a screwing tool; or making the support leg 52 a telescopic rod assembly that can be locked from the side with bolts to adjust its height; or other height-adjustable structures.

[0045] In this optional embodiment, by designing the support mechanism 5, the assembled rescue vehicle can be driven to the side of the malfunction shuttle 120 during the rescue process. After the tilting frame 2 faces the malfunction shuttle 120, the telescopic part of the horizontal telescopic component 51 extends horizontally to one side of the base 1. The height of the outrigger 52 is adjusted so that the outrigger 52 is supported on the ground, thereby ensuring the stability of the rescue vehicle in the rescue position and facilitating a smooth and efficient rescue operation.

[0046] In some optional embodiments, the fixing part of the horizontal telescopic component 51 is a sleeve 511 that is horizontally fixed to the base 1, and the telescopic part is an inner rod 512 that is axially slidably limited and connected inside the sleeve 511.

[0047] In some alternative embodiments, the fixing part of the horizontal telescopic component 51 is a telescopic drive part, and the telescopic part is a telescopic rod that is connected to the output end of the telescopic drive part. The telescopic drive part can drive the telescopic rod to extend and retract in the horizontal direction. The cooperation structure between the telescopic drive part and the telescopic rod can be selected from, but is not limited to, electric push rod assembly, electric cylinder piston rod assembly, cylinder piston rod assembly and other cooperation structures.

[0048] Continue to refer to Figures 1 to 5 In this embodiment, optionally, the fixing part provided on the base 1 includes a plurality of fixing brackets 11, each fixing bracket 11 being fixedly connected to the side of the base 1. Each fixing bracket 11 is provided with a through hole for the fixing member 12 to pass through. When assembled with the walking carrier 110 into a rescue vehicle, the fixing member 12 passes through the through hole and the mounting hole provided on the walking carrier 110 to achieve the fixing purpose.

[0049] Optionally, the fixing part 2 provided on the flipping frame 2 includes multiple fixing seats 21, each fixing seat 21 including a fixing bracket 211 and a gasket 212; the fixing bracket 211 is fixedly connected to the side of the flipping frame 2, and the fixing bracket 211 is provided with a through hole 2 for the fixing member 213 to pass through. The gasket 212 is concentrically fixed to the surface of the fixing bracket 211 facing the base 1. The gasket 212 is provided with an internal thread for threaded connection with the fixing member 213. When fixing to the frame of the fault shuttle 120, the fixing member 213 passes through the mounting hole provided on the fault shuttle 120, and then the fixing member 213 is threadedly installed in the gasket 212 to achieve the fixing purpose.
