Description

Technical Field

[0001] This utility model relates to the field of transfer vehicle technology, and in particular to a multi-functional warehouse transfer vehicle. Background Technology

[0002] Warehouse transfer vehicles are specialized transportation equipment designed specifically for warehousing and logistics scenarios. They are mainly used in enclosed or semi-enclosed areas such as warehouses, logistics centers, and factory workshops. Their core function is to enable short-distance handling, turnover, and displacement of various goods, including parts, finished products, palletized goods, and containers. Their key value lies in connecting core nodes in the warehousing process, such as "storage," "sorting," "loading and unloading," and "production workstations." Through efficient transfer, they solve the problem of safe flow of goods within limited spaces, reducing the intensity of manual handling and significantly improving the overall efficiency of warehousing operations.

[0003] Regarding the application scenarios and core functions of the aforementioned warehouse transfer vehicles, the inventors discovered that the current load-bearing surfaces of warehouse transfer vehicles are generally divided into two categories: inclined and horizontal. Each type of load-bearing surface has a specific cargo suitability scenario. For heavy cargo, the inclined load-bearing surface can effectively reduce the handling height during loading and unloading, thus reducing the labor intensity of workers. For large-volume but lightweight cargo, the horizontal load-bearing surface can maximize the use of the load-bearing space, making it easier to transport a larger quantity of cargo at a time and improving the efficiency of a single transfer.

[0004] However, existing warehouse transfer vehicles have a significant limitation of limited functionality: their load-bearing surface is mostly a fixed design, unable to flexibly switch between inclined and horizontal load-bearing surfaces according to the weight, volume, and other characteristics of the actual transported goods. This fixed design makes it difficult for the equipment to adapt to diverse cargo transfer needs, not only limiting further improvements in transfer efficiency but also significantly reducing the flexibility and convenience of equipment use, failing to fully meet the complex and ever-changing transfer requirements in warehousing scenarios. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a multi-functional warehouse transfer vehicle that increases its functionality and enhances its flexibility and convenience.

[0006] To solve the above technical problems, the present invention provides a multi-functional warehouse transfer vehicle, comprising: an inclined frame body and two handles spaced apart and connected to its upper inclined ends; an active roller assembly is connected to the lower inclined end of the lower surface of the frame body, and a foldable support wheel assembly is connected to the upper inclined end; a horizontal bearing plate assembly is provided above the frame body; and a plug-in support assembly is also included; the horizontal bearing plate assembly is detachably connected to the frame body through the plug-in support assembly.

[0007] The left and right sides of the vehicle frame are respectively connected to strip support plates. The strip support plates are provided with a number of insertion holes at intervals. The insertion support assembly includes two symmetrically arranged triangular support plates. The triangular support plate includes a triangular plate body. The upper edge of the triangular plate body is bent to one side to form a horizontal support plate. The lower inclined edge of the triangular plate body is bent to the other side to form a stabilizing plate. The lower inclined edge of the triangular plate body is connected at intervals to not less than two limiting plates that are adapted to the insertion holes.

[0008] By adopting the above technical solutions, the warehouse transfer vehicle can flexibly adjust its operation mode according to the characteristics of the goods during use, adapting to different transfer needs. When transporting heavy goods, the horizontal load-bearing plate assembly can be detached from the frame, allowing workers to place the goods stably on the inclined surface of the frame without lifting them too high. This design significantly reduces the manual lifting load during loading and unloading, effectively reducing the labor intensity of workers and improving the safety and convenience of heavy goods transfer. When transporting large-volume, light-weight goods, the limiting plate on the plug-in support assembly is first precisely inserted into the plug-in hole of the strip support plate on the side of the frame. This connection structure achieves indirect horizontal fixation between the horizontal load-bearing plate assembly and the frame. After assembly, such goods can be stacked, significantly increasing the number of goods transported at one time and directly improving warehouse transfer efficiency. At the same time, the load-bearing surface of the transfer vehicle can freely switch between the inclined surface of the frame and the upper surface of the horizontal load-bearing plate assembly, precisely adapting to the core characteristics such as the weight and volume of the actual transported goods, solving the problem of the single function of traditional equipment, and enhancing the flexibility and convenience of use. Furthermore, the transfer cart can be moved by operating the active roller assembly, eliminating the need for manual pushing by workers, further reducing labor intensity and avoiding fatigue caused by prolonged pushing. Additionally, the support wheel assembly features a foldable design, allowing it to be folded and stored when the warehouse transfer cart is not in use, effectively reducing the equipment's footprint and saving warehouse space.

[0009] In a preferred embodiment, the present invention can be further configured such that: the horizontal support plate assembly includes a support plate body and a support frame connected to its lower surface, a polygonal frame is connected to the upper plane edge of the support plate body, and a plurality of process holes are provided at intervals on the support plate body.

[0010] By adopting the above technical solution, the support frame is connected to the lower surface of the bearing plate, which effectively enhances the structural strength of the horizontal bearing plate assembly; at the same time, the polygonal frame is connected to the edge of the upper plane of the bearing plate, which can effectively prevent the goods from sliding off the surface of the bearing plate, thus taking into account both the stability of the assembly and the safety of the goods placement.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the strip support plate includes a strip plate body, end plates are bent on both sides of the strip plate body, and a plurality of reinforcing plates are connected at intervals on the lower surface of the strip plate body, the reinforcing plates being connected to the side of the vehicle frame body.

[0012] By adopting the above technical solution, one side of the reinforcing plate is connected to the strip plate body, and the other side is connected to the vehicle frame body, thereby enhancing the structural strength of the connection between the strip plate body and the vehicle frame body. The aforementioned insertion holes are provided on the strip plate body.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the active roller assembly includes a reducer and a tubular support body connected to both ends thereto. The outer end of the tubular support body is rotatably connected to a double row of roller bodies. A motor is connected to the reducer. The assembly also includes two drive shafts. The drive shafts are located in the corresponding tubular support bodies and are connected at one end to the reducer and at the other end to the double row of roller bodies. Fixed rods are respectively connected to the tubular support bodies, and the upper end of the fixed rods is connected to the vehicle frame.

[0014] By adopting the above technical solution, the tubular support body is connected and fixed to the vehicle frame body by means of the fixed rod body, thereby forming an indirect fixed structure between the tubular support body and the vehicle frame body; after the motor starts, it will drive the two drive shafts to rotate synchronously through the reducer, and then the drive shafts will drive the corresponding double row of rollers to roll, ultimately achieving the functional goal of automatic driving.

[0015] In a preferred embodiment, the present invention can be further configured as follows: the support wheel assembly includes an H-shaped frame, with universal rollers connected to both ends of the bottom of the H-shaped frame, and U-shaped seats hinged to both ends of the top of the H-shaped frame, the U-shaped seats being connected to the vehicle frame, and also includes two symmetrically arranged hinged support rods, which are suitable for preventing the H-shaped frame from swinging.

[0016] By adopting the above technical solution, the omnidirectional rollers are connected and fixed to the vehicle frame via an H-shaped frame, thereby achieving the function of rolling support for the vehicle frame. The top of the H-shaped frame is hinged to the U-shaped seat on the vehicle frame, and under the action of the hinged support rod, the H-shaped frame and the vehicle frame maintain a fixed angle, ensuring that the H-shaped frame and the omnidirectional rollers stably support one end of the vehicle frame. When storage is required, bending the hinged support rod drives the H-shaped frame and the vehicle frame together, achieving convenient storage. The top of the H-shaped frame and the U-shaped seat are connected by a pin, improving the ease of installation.

[0017] In a preferred embodiment, the present invention can be further configured as follows: the hinged support rod includes a hinged rod one and a hinged rod two with their ends hinged together. The opposing ends of the hinged rod one and the hinged rod two are hinged together by bolts and nuts. A first screw is passed through the upper inclined end of the hinged rod one. A nut is screwed to one end of the first screw, and a nut is screwed to the other end of the first screw, which passes through the frame body. A support bolt body is passed through the lower inclined end of the hinged rod two. The threaded end of the support bolt body passes through the H-shaped frame body and is screwed to the nut. The invention also includes a stop rod component, a limit rod component, and a U-shaped drive rod component for driving the hinged rod two to swing.

[0018] The first hinge rod is provided with a support hole and a folding hole at intervals, the second hinge rod is provided with a support hole and a folding hole at intervals, and the stop rod component includes a stop rod, an elastic double arched limiting frame and a rectangular block connected to one end of the stop rod. The two ends of the elastic double arched limiting frame are respectively inserted into the rectangular block and are eccentrically set.

[0019] The limiting rod component includes a limiting rod body inserted into the second hinge rod and an arc-shaped groove provided on the first hinge rod;

[0020] The U-shaped drive rod component includes a U-shaped drive rod and two L-shaped baffles. The L-shaped baffles are respectively provided with mounting holes. The two ends of the U-shaped drive rod are respectively connected to rotating rods. The outer end of the rotating rod passes through the hinge rod two. The support bolt body passes through the mounting hole.

[0021] By adopting the above technical solution, the upper inclined end of hinge rod one is hinged to the frame body through the first screw and nut, and the lower inclined end of hinge rod two is hinged to the H-shaped frame body through the support bolt and nut. When the support hole one on hinge rod one coincides with the support hole two on hinge rod two, the stop rod is passed through support hole one and support hole two, and the elastic double-arched limiting bracket is sleeved on the outer side of the end of the stop rod away from the rectangular block, preventing the stop rod from detaching from support hole one and support hole two. At this time, hinge rod one and hinge rod two are in the unfolded state, and hinge rod one and hinge rod two provide limiting support for the H-shaped frame body, so that the H-shaped frame body is fixed relative to the frame body. When the support wheel assembly needs to be retracted relative to the vehicle frame, the stop bar is removed. Hinged rod one and hinged rod two are then swung relative to each other at a certain angle, aligning folding hole one on hinged rod one with folding hole two on hinged rod two. The stop bar is then passed through the inner holes of folding holes one and two. A flexible double-arched limiting bracket is then fitted onto the outer side of the stop bar, away from the rectangular block, preventing the stop bar from disengaging from folding holes one and two. At this point, the H-shaped frame and the vehicle frame reach a stable retracted state, thus reducing the footprint of the warehouse transfer vehicle. During the relative swinging of hinged rod one and hinged rod two, the limiting rod moves into the arc-shaped groove on hinged rod one, further preventing the relative swinging of hinged rod one and hinged rod two, allowing support holes one and two to quickly align. When it is necessary to close the support wheel assembly to the frame, press the U-shaped drive rod and use the nut on the support bolt as the fulcrum. This will drive hinge rod one and hinge rod two to swing relative to each other, achieving the purpose of closing the support wheel assembly to the frame and improving the convenience of operation. When it is necessary to unfold the support wheel assembly to the frame, pull the U-shaped drive rod upward and use one side of the L-shaped baffle as the fulcrum. This will drive hinge rod one and hinge rod two to swing in opposite directions, causing the support wheel assembly to separate from the frame to form a certain angle and provide support, further improving the convenience of operation.

[0022] In a preferred embodiment, this utility model may be further configured to include U-shaped side guardrail assemblies disposed on the left and right sides of the vehicle frame.

[0023] The U-shaped side guardrail assembly includes a U-shaped side guardrail body, with sleeves fitted at both ends of the U-shaped side guardrail body. The sleeves are mounted on the vehicle frame and fixedly connected. A fixing nut is connected to the sleeve, and a locking handle is screwed into the fixing nut.

[0024] By adopting the above technical solution, the sleeve body is fixed to the vehicle frame, and the two ends of the U-shaped side guardrail are respectively inserted into the corresponding sleeve bodies. Then, the locking handle is rotated to make the ends of the U-shaped side guardrails make tight contact with the U-shaped side guardrails, achieving the purpose of relatively fixing the U-shaped side guardrails to the vehicle frame. U-shaped side guardrails are installed on both sides of the vehicle frame, which prevent goods from falling off the sides of the vehicle frame, improving the safety of the warehouse transfer vehicle.

[0025] In a preferred embodiment, the present invention may be further configured as follows: it also includes a controller and braking components for braking the double-row roller bodies. The braking components include brake discs mounted on the double-row roller bodies and brake levers mounted on a handle. Brake bars are connected between the brake levers and the brake discs. The controller is electrically connected to the motor and is suitable for controlling the motor to rotate forward, rotate in reverse, and stop rotating.

[0026] By adopting the above technical solution, gripping the brake lever on the handlebars causes the brake disc to brake the double-row rollers via the brake pads, thus improving the safety of the warehouse transfer vehicle. The controller allows for easy control of the motor's forward, reverse, and stop rotation; that is, the warehouse transfer vehicle can move forward, backward, or stop.

[0027] In summary, this utility model has at least one of the following beneficial technical effects:

[0028] 1. When transporting heavy goods, the horizontal load-bearing plate assembly can be disassembled and the goods placed on the inclined surface of the vehicle frame, reducing the load of manual lifting, reducing the labor intensity of the work, and improving the safety and convenience of heavy goods transfer; when transporting large-volume, light-weight goods, the horizontal load-bearing plate can be fixed with the help of the plug-in support assembly, and the goods can be stacked, improving the transfer efficiency.

[0029] 2. The load-bearing surface of the warehouse transfer vehicle can be switched between the inclined surface of the vehicle frame and the horizontal surface of the horizontal load-bearing plate assembly to adapt to different goods, thus solving the problem of the single function of traditional transfer vehicles.

A horizontal bearing plate assembly 50 is provided above the frame body 1, and it also includes a plug-in support assembly 60. The horizontal bearing plate assembly 50 is detachably connected to the frame body 1 through the plug-in support assembly 60.

[0057] The left and right sides of the frame body 1 are respectively connected to strip support plates 70. The strip support plates 70 are provided with a number of insertion holes 11 at intervals. The insertion support assembly 60 includes two symmetrically arranged triangular support plates 61. The triangular support plates 61 include triangular plates 611.

[0058] The horizontal support plate assembly 50 includes a support plate body 51 and a support frame 52 connected to its lower surface. A polygonal frame 53 is connected to the upper edge of the support plate body 51, and a plurality of process holes 54 are provided at intervals on the support plate body 51.

The tubular support bodies 32 are connected and fixed to the vehicle frame 1 via the fixed rods 36, thus forming an indirect fixed structure relative to the vehicle frame 1. When the motor 34 starts, it drives the two drive shafts 35 to rotate synchronously through the reducer 31, which in turn drives the corresponding double-row roller bodies 33 to roll, ultimately achieving the goal of automatic driving.

[0061] The support wheel assembly 40 includes an H-shaped frame 41, with universal rollers 42 connected to both ends of the bottom of the H-shaped frame 41, and U-shaped seats 43 hinged to both ends of the top of the H-shaped frame 41. The U-shaped seats 43 are connected to the frame body 1. It also includes two symmetrically arranged hinged support rods 44, suitable for preventing the H-shaped frame 41 from swinging. The universal rollers 42 are fixed to the frame body 1 via the H-shaped frame 41, thus providing rolling support for the frame body 1. The top of the H-shaped frame 41 is hinged to the U-shaped seats 43 on the frame body 1, and under the action of the hinged support rods 44, the H-shaped frame 41 and the frame body 1 maintain a fixed angle, ensuring that the H-shaped frame 41 and the universal rollers 42 stably support one end of the frame body 1. When storage is required, bending the hinged support rods 44 drives the H-shaped frame 41 to close with the frame body 1, achieving convenient storage. The top of the H-shaped frame 41 is connected to the U-shaped base 43 by a pin, which improves the ease of installation.

[0062] The hinged support rod 44 includes a hinge rod 441 and a hinge rod 442 with their ends hinged together. The opposing ends of the hinge rod 441 and the hinge rod 442 are hinged together by bolts and nuts. A first screw 443 is threaded through the upper inclined end of the hinge rod 441. One end of the first screw 443 is screwed with a nut, and the other end passes through the frame body 1 and is screwed with a nut. A support bolt body 444 is threaded through the lower inclined end of the hinge rod 442. The threaded end of the support bolt body 444 passes through the H-shaped frame body 41 and is screwed with a nut. The support rod also includes a stop rod component 445, a limit rod component 446, and a U-shaped drive rod component 447 for driving the hinge rod 442 to swing. The hinge rod 441 is provided with a support hole 12 and a folding hole 13 at intervals. The hinge rod 442 is provided with a support hole 14 and a folding hole 13 at intervals. The second stacked hole 15 and the stop rod component 445 include a stop rod 4451, an elastic double-arched limiting frame 4452 and a rectangular block 4453 connected to one end of the stop rod 4451. The two ends of the elastic double-arched limiting frame 4452 are respectively inserted into the rectangular block 4453 and are eccentrically arranged. The limiting rod component 446 includes a limiting rod body 4461 inserted into the second hinge rod 442 and an arc-shaped groove 4462 provided on the first hinge rod 441. The U-shaped drive rod component 447 includes a U-shaped drive rod 4471 and two L-shaped baffles 4472. The L-shaped baffles 4472 are respectively provided with mounting holes 4473. The two ends of the U-shaped drive rod 4471 are respectively connected to rotating rods 4474. The outer end of the rotating rod 4474 passes through the second hinge rod 442. The support bolt body 444 passes through the mounting hole 4473. The upper end of hinge rod 441 is hinged to the frame 1 via a first screw 443 and a nut. The lower end of hinge rod 442 is hinged to the H-shaped frame 41 via a support bolt 444 and a nut. When the support hole 12 on hinge rod 441 coincides with the support hole 14 on hinge rod 442, the stop rod 4451 passes through the support holes 12 and 14. The elastic double-arched limiting bracket 4452 is then fitted onto the outer side of the stop rod 4451 away from the rectangular block 4453, preventing the stop rod 4451 from disengaging from the support holes 12 and 14. At this time, hinge rods 441 and 442 are in the extended state, providing limiting support for the H-shaped frame 41, thus fixing the H-shaped frame 41 relative to the frame 1.When the support wheel assembly 40 needs to be retracted relative to the frame body 1, the stop rod 4451 is removed, and the hinge rod 1 441 and the hinge rod 2 442 are swung relative to each other at a certain angle. The folding hole 13 on the hinge rod 1 441 and the folding hole 2 15 on the hinge rod 2 442 are aligned. Then, the stop rod 4451 is passed through the inner holes of the folding hole 1 13 and the folding hole 2 15. The elastic double arched limit frame 4452 is fitted on the outer side of the stop rod 4451 away from the rectangular block 4453, preventing the stop rod 4451 from disengaging from the folding hole 1 13 and the folding hole 2 15. At this time, the H-shaped frame body 41 and the frame body 1 reach a stable retracted state, thereby reducing the footprint of the warehouse transfer vehicle. During the relative swinging of hinge rod 441 and hinge rod 442, the limiting rod 4461 moves into the arc-shaped groove 4462 on hinge rod 441, thereby preventing hinge rod 441 and hinge rod 442 from continuing to swing relative to each other, so that support hole 12 and support hole 14 can quickly achieve the purpose of aligning. When it is necessary to operate the support wheel assembly 40 and the frame body 1 to be brought together, press the U-shaped drive rod 4471 and use the nut on the support bolt body 444 as the support point, thereby driving hinge rod 441 and hinge rod 442 to swing relative to each other, so as to achieve the purpose of bringing the support wheel assembly 40 and the frame body 1 together, improving the convenience of operation. When it is necessary to operate the support wheel assembly 40 and the frame body 1 to unfold, pull the U-shaped drive rod 4471 upward and use one side of the L-shaped baffle 4472 as the support point, thereby driving the first hinge rod 441 and the second hinge rod 442 to swing in opposite directions, so that the support wheel assembly 40 and the frame body 1 separate to form a certain angle and form a support effect, which improves the convenience of operation.

[0063] It also includes U-shaped side guardrail assemblies 80 installed on the left and right sides of the vehicle frame 1. Each U-shaped side guardrail assembly 80 includes a U-shaped side guardrail body 81, with sleeves 82 fitted to both ends of the U-shaped side guardrail body 81. The sleeves 82 are threaded through and fixedly connected to the vehicle frame 1, and a fixing nut 83 is connected to each sleeve 82. A locking handle 84 is screwed into the fixing nut 83. The sleeves 82 are fixed to the vehicle frame 1. The two ends of the U-shaped side guardrail body 81 are threaded through the corresponding sleeves 82, and the locking handle 84 is rotated to ensure a tight contact between the ends and the U-shaped side guardrail body 81, thus achieving relative fixation between the U-shaped side guardrail body 81 and the vehicle frame 1. The U-shaped side guardrail bodies 81 installed on both sides of the vehicle frame 1 prevent goods from falling from the sides of the vehicle frame 1, improving the safety of the warehouse transfer vehicle.

[0064] It also includes a controller 16 and braking assemblies 90 for braking the double-row roller bodies 33. Each braking assembly 90 includes a brake disc 91 mounted on the double-row roller bodies 33 and a brake lever 92 mounted on a handlebar 2. Brake bars 93 connect the brake lever 92 to the brake disc 91. The controller is electrically connected to the motor 34 and is suitable for controlling the motor 34 to rotate forward, reverse, and stop. Gripping the brake lever 92 on the handlebar 2 causes the brake lever 92 to drive the brake disc 91 through the brake bars 93, thus braking the double-row roller bodies 33 and improving the safety of the warehouse transfer vehicle. Operating the controller 16 allows for easy control of the motor 34's forward, reverse, and stop rotation; that is, the warehouse transfer vehicle can move forward, backward, or stop.

[0065] The implementation principle of this embodiment is as follows: During use, the warehouse transfer vehicle can flexibly adjust its operation mode according to the characteristics of the goods to adapt to different transfer needs. When transporting heavy goods: simply remove the horizontal bearing plate assembly 50 from the frame 1, and workers can place the goods stably on the inclined surface of the frame 1 without lifting them too high. This design significantly reduces the manual lifting load during loading and unloading, effectively reducing the labor intensity of workers and improving the safety and convenience of heavy goods transfer. When transporting large-volume, light-weight goods: first, accurately insert the limiting plate 614 on the plug-in support assembly 60 into the plug-in hole 11 of the strip support plate 70 on the side of the frame 1. This connection structure achieves indirect horizontal fixation between the horizontal bearing plate assembly 50 and the frame 1. After assembly, such goods can be stacked, significantly increasing the number of goods transported in a single trip and directly improving warehouse transfer efficiency. Meanwhile, the load-bearing surface of the transfer vehicle can freely switch between the inclined surface of the frame 1 and the upper surface of the horizontal load-bearing plate assembly 50, precisely adapting to the core characteristics such as the weight and volume of the actual transported goods. This solves the problem of the single function of traditional equipment and enhances the flexibility and convenience of use. Furthermore, the transfer vehicle can be driven by operating the active roller assembly 30, eliminating the need for manual pushing by workers, further reducing labor intensity and avoiding fatigue caused by prolonged pushing. Additionally, the support wheel assembly 40 features a foldable design, allowing it to be folded and stored when the warehouse transfer vehicle is not in use, effectively reducing the equipment's footprint and saving warehouse space.
