Description

Technical Field

[0001] The present invention relates to the technical field of cargo handling, and particularly to an automatic guided vehicle for on-vehicle cargo handling and transportation. Background Art

[0002] Handling and transportation equipment refers to machinery used to move, lift, load and unload, and short-distance transport materials or goods. It can be used to complete the stacking, unstacking, transportation of goods in warehouses and yards, as well as the lifting, transportation and handling of goods in the cabin, vehicle, and warehouse. Common ones include small forklifts pushed by hand, which are inexpensive and easy to use. At the same time, they can be vehicle-mounted for convenient and rapid unloading. However, at present, such forklifts used for cargo handling and transportation have high requirements for the usage scenarios and need to work efficiently in a stable and spacious environment. If they encounter narrow, potholed, uneven or roadblocked roads, it is difficult to move. Forced movement is likely to cause the goods to fall, resulting in economic losses due to the goods being knocked and damaged.

[0003] The patent with the patent number CN202321351928.5 discloses an on-vehicle cargo handling and transportation device. In this patent, motor A drives the lead screw to rotate, and the rotating lead screw drives the lifting plate to adjust the height. The lifting plate drives two groups of fork plates to adjust the height, which facilitates the adjustment of the height of the fork plates. The electric turntable drives the cross plate to rotate, and the cross plate drives the left side of the lifting device's rotating support frame to prevent interference between the fork plates and the lifting device when the fork plates drive the goods to rise, improving the reliability. The winch is used for winding and unwinding the rope, and the hook is installed at the lower end of the rope. When hoisting goods, the hook is hooked on the goods to be hoisted, and then the winch winds the rope to drive the hook to lift the goods, completing the hoisting of the goods. It facilitates the hoisting of goods. The slider drives the hook to adjust the position through the winch, so that the hook moves to a position convenient for hoisting the goods. It facilitates the hoisting of goods. Wear-resistant coatings are provided on two groups of fork plates. Through the above settings, the wear-resistant effect of the two groups of fork plates is improved, and the service life of the fork plates is extended. Although this patent solves the above problems, it still has the problem of few usage scenarios and being unable to move stably on complex road conditions to ensure the safety of goods. Therefore, it is very necessary to design an automatic guided vehicle for on-vehicle cargo handling and transportation that is not limited to any usage scenario and can move stably on roads with complex road conditions to ensure the safety of goods. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic guided vehicle for on-vehicle cargo handling and transportation to solve the problems raised in the above background art.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an automatic guided vehicle for loading and unloading cargo on a vehicle, comprising a crank forklift, the crank forklift also comprising an obstacle surmounting device, the obstacle surmounting device comprising an elastic telescopic structure and a toggle linkage structure, the elastic telescopic structure comprising a rear wheel, a front wheel, and a telescopic rod, the rear wheel is rotatably connected to the bottom of the crank forklift, the front wheel is arranged at the bottom of the crank forklift, the telescopic rod is hingedly connected to the bottom of the crank forklift, the toggle linkage structure comprises an extrusion rod, a toggle connector, a swing rod, and a connecting rod, the extrusion rod is rotatably connected to both sides of the front wheel, the toggle connector is hingedly connected to both sides of the extrusion rod, the swing rod is hingedly connected to the inner side of the toggle connector, the connecting rod is hingedly connected to both sides of the swing rod, the connecting rod is hingedly connected to both sides of the extrusion rod, the swing rod is hingedly connected to the front side of the bottom of the crank forklift, the telescopic rod is hingedly connected to the inner side of the toggle connector, and the staff pushes the crank forklift The vehicle drives the rear wheel and the front wheel to move, and the telescopic rod enables the front wheel to move up and down to a certain extent, so as to cross the obstacle, so that the application range of the articulated arm forklift is increased and it can adapt to different road conditions. When the front wheel is moving, it will produce a certain fluctuation according to the curvature of the road surface when it touches an obstacle or a pothole. When the front wheel fluctuates, the force will be transmitted to the extrusion rod, and the extrusion rod will squeeze the front end of the toggle joint connector, and the toggle joint connector will tilt or tilt forward, thereby squeezing the telescopic rod connected to the rear end. The elastic effect generated by the extrusion of the telescopic rod causes the toggle joint connector to recover, and at the same time, the toggle joint connector is offset so that the axis is fixed by the swing rod, and the offset force is reduced by the swing rod. The extrusion rod is connected to the swing rod through a connecting rod, so that the extrusion rod is supported and the shape is kept stable, so that the extrusion rod and the toggle joint connector drive the front wheel to deviate without changing the shape, so that the front wheel can stably cross obstacles and potholes, thereby ensuring the stability of the articulated arm forklift in adapting to multiple road conditions.

[0006] According to the above technical solution, an anti-tipping device is provided inside the front wheel. The anti-tipping device includes a pushing structure and an anti-tipping structure. The pushing structure includes a rotating rod, a vertical transmission member, and a guide rail. The rotating rod rotates through to the front side of the bottom of the articulated forklift. The vertical transmission member is sleeved on the front end of the rotating rod. The guide rail is fixedly connected to both sides of the vertical transmission member. The anti-tipping structure includes a trapezoidal slider, a cross plate, a slide rail, and a rotating sliding basket. The trapezoidal slider is slidably connected to the inside of the guide rail. The cross plate slides through both sides of the articulated forklift. The slide rail is fixedly connected to both sides of the articulated forklift. The rotating sliding basket is sleeved outside the cross plate. The guide rail is fixedly connected to the bottom of the articulated forklift. A ball screw is provided inside the guide rail. The ball screw is rotatably connected to both sides of the vertical transmission member. The trapezoidal slider is sleeved on the surface of the ball screw.

The rotating sliding basket is rotatably connected to the rotating shafts. The rotating shafts are slidably connected to the inside of the slide rail. Rotate the rotating rod, and the rotating rod drives the internal parts of the vertical transmission member to rotate, vertically conducting the rotating force to the ball screw inside the guide rail. The ball screw drives the trapezoidal slider to move left and right reciprocally. When the trapezoidal slider moves, the convex plate at the top is inserted into the bottom of the cross plate, driving the cross plate to translate to both sides or contract inward, making the contact area between the articulated forklift and the goods larger and the support effect better, preventing the goods from tipping over due to unstable center of gravity caused by excessive volume. When the cross plate extends to both sides to the end, this will slide the rotating sliding basket to both sides of the slide rail. The end of the cross plate is caught by the rotating sliding basket, but the whole is pushed by the rotating sliding basket to slide to both sides, further increasing the support area and making the adjustable range of the support larger, capable of adapting to more different requirements for goods loading and unloading.

[0007] According to the above technical scheme, a fixing device is arranged above the cross plate, and the fixing device includes a binding structure and a clamping and fixing structure, and the binding structure includes a storage cavity, a rope, and a transmission wheel. The storage cavity is opened on the inner side of the cross plate, and the rope slides through both sides of the storage cavity, and the transmission wheel is fixedly connected to the surface of the rotating rod, and the clamping and fixing structure includes a synchronous belt, a fixed shaft, a winch, and a hook column. The synchronous belt is transmission-connected to the surface of the transmission wheel, the fixed shaft is fixedly connected to the top of the articulated arm forklift, the winch is rotatably connected to the front side of the fixed shaft, and the hook column is fixedly connected to the bottom of the articulated arm forklift, the rope is wrapped around the outside of the winch, and the synchronous belt is transmission-connected to the surface of the winch, and the storage cavity stores a rope, which passes through both sides of the storage cavity and is in a loose state like shoelaces. When the goods are lifted, they are usually hung The rope at the front end of the hook column and the articulated arm forklift is pulled to the top of the cargo, and the winch is turned to shrink the rope to tie the cargo, so that the cargo is fixed and will not shake or vibrate during transportation, causing damage to the internal items, thereby improving the safety of the cargo. The rotating rod is turned, and the rotating rod drives the transmission wheel to rotate, and the transmission wheel drives the synchronous belt to rotate, and the synchronous belt drives the winch to rotate. The winch rotates to wind up the rope, and while the rope is winding, the cross plate is pulled, and the cross plate is pulled out from the rotating slide basket, and when the end of the cross plate is stuck by the rotating slide basket, the rotating slide basket rotates, and the rotating slide basket rotates to change the cross plate from a parallel state to a vertical state. When the winch continues to rotate, the rope shrinks, causing the rope to pull the cross plate, and the cross plate shrinks inward to fit the two sides of the cargo and clamps the cargo, making the cargo more stable and will not be damaged by the environment, thereby causing economic losses.

[0008] According to the above technical solution, a battery protection device is provided on the rear side of the winch, and the battery protection device includes a protection structure and a disassembly structure.

The protection box provides protection for the battery and is easy to operate. The protection box prevents the battery from being exposed to the air and damaged by environmental factors, resulting in a reduction in service life. It also prevents the battery from causing harm to personnel. When the battery needs to be started, just open the side panel. When the battery needs to be inspected, pull the handle to the rear to drive the sliding baffle to slide out the protection box. At this time, the two sides of the battery lose their barrier, which makes it convenient to disassemble the battery for inspection and manual operation.

Specific embodiments

[0012] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0013] Please refer to Figures 1-4, an embodiment of the present invention is: an automatic guided vehicle for loading, unloading and handling vehicle-mounted goods, including a articulated forklift 1. The articulated forklift 1 further includes an obstacle-crossing device 2. The obstacle-crossing device 2 includes an elastic telescopic structure and a knuckle linkage structure. The elastic telescopic structure includes a rear wheel 21, a front wheel 22, and a telescopic rod 23. The rear wheel 21 is rotatably connected to the bottom of the articulated forklift 1. The front wheel 22 is arranged at the bottom of the articulated forklift 1. The telescopic rod 23 is hinged to the bottom of the articulated forklift 1. The operator pushes the articulated forklift 1 to drive the rear wheel 21 and the front wheel 22 to move. The telescopic rod 23 enables the front wheel 22 to move up and down to a certain extent, so as to cross obstacles, increasing the applicable range of the articulated forklift 1 and enabling it to adapt to different road conditions. The knuckle linkage structure includes a pressing rod 24, a knuckle connecting piece 25, a swing rod 26, and a connecting rod 27. The pressing rod 24 is rotatably connected to both sides of the front wheel 22. The knuckle connecting piece 25 is hinged to both sides of the pressing rod 24. The swing rod 26 is hinged to the inner side of the knuckle connecting piece 25. The connecting rod 27 is hinged to both sides of the swing rod 26. The connecting rod 27 is hinged to both sides of the pressing rod 24. The swing rod 26 is hinged to the front side of the bottom of the articulated forklift 1. The telescopic rod 23 is hinged to the inner side of the knuckle connecting piece 25. When the front wheel 22 moves and touches an obstacle or a pothole, it will generate a certain undulation according to the road curvature. When the front wheel 22 undulates, the force will be transmitted to the pressing rod 24. The pressing rod 24 presses the front end of the knuckle connecting piece 25, causing the knuckle connecting piece 25 to tilt up or forward, thereby squeezing the telescopic rod 23 connected to the rear end. After being squeezed, the elastic action of the telescopic rod 23 causes the knuckle connecting piece 25 to return to its original state. At the same time, the offset of the knuckle connecting piece 25 causes the axis to be fixed by the swing rod 26, and the offset force is reduced by the swing rod 26. The pressing rod 24 is connected to the swing rod 26 through the connecting rod 27, so that the pressing rod 24 is supported and its shape is kept stable, enabling the pressing rod 24 and the knuckle connecting piece 25 to drive the front wheel 22 to offset without changing their shapes, so that the front wheel 22 can stably cross obstacles and potholes, ensuring the stability of the articulated forklift 1 under multi-road conditions; Working principle: The staff pushes the articulated forklift 1, driving the rear wheel 21 and the front wheel 22 to move. The telescopic rod 23 enables the front wheel 22 to move up and down to a certain extent, so as to cross obstacles, so that the application range of the articulated forklift 1 is increased and it can adapt to different road conditions. When the front wheel 22 moves, it will produce a certain fluctuation according to the curvature of the road surface when it touches obstacles or potholes. When the front wheel 22 fluctuates, the force will be transmitted to the squeezing rod 24, and the squeezing rod 24 squeezes the front end of the toggle connector 25, and the toggle connector 25 tilts or tilts forward, thereby the telescopic rod 23 connected at the rear end is pressed. The rod 23 causes extrusion, and the elastic effect generated by the extrusion of the telescopic rod 23 causes the toggle connector 25 to recover. At the same time, the toggle connector 25 deviates so that the axis is fixed by the swing rod 26, and the deviated force is reduced by the swing rod 26. The extrusion rod 24 is connected to the swing rod 26 through the connecting rod 27, so that the extrusion rod 24 is supported and the shape is kept stable, so that the extrusion rod 24 and the toggle connector 25 drive the front wheel 22 to deviate without changing the shape, so that the front wheel 22 can stably cross obstacles and potholes, thereby ensuring the stability of the articulated boom forklift 1 in adapting to multiple road conditions.
