Description

Technical Field

[0001] The present invention relates to the technical field of forklifts, and more specifically, to an anti-overturning multifunctional forklift. Background Art

[0002] A forklift is an industrial handling vehicle, referring to various wheeled handling vehicles for loading, unloading, stacking, and short-distance transportation of palletized goods. There are many types of forklifts. A hoisting forklift is a forklift equipped with a hoisting mechanism to lift goods for handling.

[0003] Currently, when a hoisting forklift lifts and transports goods, when passing through some narrow slopes or difficult turns, the goods will swing. It is time-consuming and laborious for workers to eliminate the swing, and it is easy to delay working hours. At the same time, the swinging of the goods endangers the safety of the workers and the hoisting forklift equipment, and is likely to cause the forklift to overturn. The Chinese patent with the publication number

[0004] CN111874837B discloses a support device for a forklift. When the forklift passes through some turning slopes or roads with a large slope, the wheels can be in contact with the ground. At this time, the force on the wheels can greatly reduce the possibility of the forklift overturning; when the forklift passes through some uneven roads, a downward force can be applied to the wheels to lift the entire forklift, so that the ground clearance of the chassis is higher and it will not be scratched or blocked by the uneven road surface when passing through, improving its passing performance. The above solution has a poor effect of reducing the forklift overturning by the contact between the wheels and the road surface. Especially when lifting heavy goods, if the forklift tilts, the wheels are not enough to support the tilted forklift, resulting in overturning, damaging the goods and endangering the personal safety of the workers. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and provide an anti-overturning multifunctional forklift. The hoisting component is used to lift the goods, and when the goods shake, it can drive the swinging component to swing, push the hydraulic oil to adjust the center of gravity of the counterweight on the vehicle body, maintain the balance and stability of the forklift, and prevent overturning.

[0006] The technical solutions of the present invention are as follows:

[0007] An anti-rollover multifunctional forklift, comprising a vehicle body, a lifting mechanism arranged at the front end of the vehicle body, and a counterweight arranged on one side of the lifting mechanism. A sliding plate is arranged on the lifting mechanism, a lifting arm is arranged on the sliding plate, a lifting hole is formed in the lifting arm, a lifting component is arranged on the lifting hole, a swinging component is arranged on the lifting component, and an adjusting component is arranged on the counterweight. The lifting mechanism is used to drive the lifting arm to lift on the vehicle body. The lifting component is used to lift the cargo box and drive the swinging component to move horizontally when it shakes. The adjusting component adjusts the center of gravity of the counterweight on the vehicle body under the swing of the swinging component.

[0008] As a preference, the lifting component includes a fixed shaft fixedly arranged on the lifting hole, a load-bearing block rotatably arranged on the fixed shaft, and a lifting rope fixedly arranged on the load-bearing block.

[0009] As a preference, the swinging component includes a swinging rod hinged on the load-bearing block, a fixed rod fixedly arranged on the lifting hole, a first piston hinged on the swinging rod, and a hydraulic pipe fixedly arranged on the vehicle body. The swinging rod is rotatably arranged on the fixed rod, the first piston is slidably arranged in the hydraulic pipe, and both the hydraulic pipe and the swinging rod are arranged as telescopic structures.

[0010] As a preference, the adjusting component includes a sliding groove formed in the vehicle body, a bearing plate slidably arranged in the sliding groove, a second piston fixedly arranged on the bearing plate, and a spring connecting the sliding groove and the bearing plate. The second piston is slidably arranged in the hydraulic pipe, and the counterweight is arranged on the bearing plate.

[0011] As a preference, the diameter of the first piston is larger than that of the second piston.

[0012] As a preference, the caliber of the hydraulic pipe at the first piston is larger than that of the hydraulic pipe at the second piston.

[0013] As a preference, a pulley is arranged on the second piston.

[0014] As a preference, a soft pad is arranged on the swinging rod.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention is provided with a lifting component. The goods are fixed by the lifting rope. When the goods shake, it can drive the load-bearing block to swing on the fixed shaft, drive the swinging rod and the first piston to move in the same side direction, so that the counterweight can be accurately offset automatically according to the inclination direction of the forklift, thereby ensuring that the forklift body is more stable when transporting goods and will not shift or shake.

[0017] 2. The present invention is provided with a swing assembly and an adjustment assembly. When the swing rod and the first piston move in one direction, the first piston pushes the hydraulic oil, and the hydraulic oil pushes the second piston to move in the opposite direction, driving the counterweight to move, thereby adjusting the lateral center of gravity of the vehicle body, balancing the vehicle body, and preventing the vehicle body from tipping over.

[0018] In summary, the present invention has the advantages of automatic center of gravity adjustment and strong practicability, and is suitable for the forklift technical field. BRIEF DESCRIPTION OF THE DRAWINGS

The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0030] As Figures 1 to 6As shown in the figure, a rollover-proof multi-functional forklift includes a vehicle body 1, a lifting mechanism 2 provided at the front end of the vehicle body 1, and a counterweight 3 provided on one side of the lifting mechanism 2. A sliding plate 4 is provided on the lifting mechanism 2, a lifting arm 5 is provided on the sliding plate 4, a lifting hole 6 is provided on the lifting arm 5, a lifting component 7 is provided on the lifting hole 6, a swinging component 8 is provided on the lifting component 7, and an adjusting component 9 is provided on the counterweight 3. The lifting mechanism 2 is used to drive the lifting arm 5 to lift on the vehicle body 1. The lifting component 7 is used to lift the cargo box and drive the swinging component 8 to move horizontally when it shakes. The adjusting component 9 adjusts the center of gravity of the counterweight 3 on the vehicle body 1 under the movement of the swinging component 8. Among them, the lifting mechanism 2 includes a hydraulic cylinder, a sprocket rotatably connected to the top of the hydraulic cylinder through a rotating shaft, and a chain provided on the sprocket. One end of the chain is fixedly connected to the vehicle body 1, and the other end of the chain is fixedly connected to the sliding plate 4. The hydraulic cylinder is used to push the sprocket to rise. The sprocket drives the chain, and then the sliding plate 4 rises, thereby driving the lifting arm 5 to rise.

[0031] As Figure 2 and Figure 4 shown in the figure, the lifting component 7 includes a fixed shaft 71 fixedly provided on the lifting hole 6, a load-bearing block 72 rotatably provided on the fixed shaft 71, and a lifting rope 73 fixedly provided on the load-bearing block 72. When in use, the goods are fixed through the lifting rope 73. When the goods shake, the load-bearing block 72 can be driven to swing on the fixed shaft 71.

[0032] As Figure 4 shown in the figure, the swinging component 8 includes a swinging rod 81 hinged to the load-bearing block 72, a fixed rod 82 fixedly provided on the lifting hole 6, a first piston 83 hinged to the swinging rod 81, and a hydraulic pipe 84 fixedly provided on the vehicle body 1. The swinging rod 81 is rotatably provided on the fixed rod 82, the first piston 83 is slidably provided in the hydraulic pipe 84, and both the hydraulic pipe 84 and the swinging rod 81 are provided as telescopic structures. Among them, hydraulic oil is provided in the hydraulic pipe 84. When in use, when the goods shake and drive the lifting rope 73 and the load-bearing block 72 to swing to one side, the swinging rod 81 and the first piston 83 are driven to move in the same side direction.

[0033] As Figures 4 to 6As shown, the adjusting assembly 9 includes a sliding groove formed in the vehicle body 1, a bearing plate 91 slidably disposed in the sliding groove, a second piston 92 fixedly disposed on the bearing plate 91, and a spring connecting the sliding groove and the bearing plate 91. The second piston 92 is slidably disposed in the hydraulic pipe 84. The counterweight 3 is disposed on the bearing plate 91. During use, when the goods shake and tilt to one side, the swing rod 81 and the first piston 83 move in the same side direction. The first piston 83 pushes the hydraulic oil, and the hydraulic oil pushes the second piston 92 in the opposite side direction, driving the counterweight 3 to move. After moving, the counterweight 3 remains stationary under the action of the hydraulic oil, thereby adjusting the center of gravity of the vehicle body 1, balancing the vehicle body 1, and preventing the vehicle body 1 from tipping over. In addition, the spring plays a buffering role.

[0034] As Figures 3 to 6 shown, the diameter of the first piston 83 is larger than that of the second piston 92, and this method can accelerate the moving speed of the hydraulic oil at the second piston 92.

[0035] As Figure 5 shown, the caliber of the hydraulic pipe 84 at the first piston 83 is larger than that of the hydraulic pipe 84 at the second piston 92, accelerating the flowing speed and impact force of the hydraulic oil at the second piston 92 to drive the counterweight 3 to move.

[0036] As Figure 5 shown, a pulley 10 is disposed on the second piston 92 to reduce friction and make the movement of the counterweight 3 smoother.

[0037] Embodiment 2

[0038] As Figure 4 shown, the same or corresponding components as those in Embodiment 1 adopt the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 will be described below; the difference between this Embodiment 2 and Embodiment 1 is that a soft pad is disposed on the swing rod 81.

[0039] Here, in this embodiment, by disposing a soft pad on the swing rod 81, the wear is reduced when it touches the lifting hole 6, and the service life is prolonged.

[0040] Working process;

[0041] The goods are fixed by the lifting rope 73. When the goods shake, driving the lifting rope 73 and the load-bearing block 72 to swing to one side, driving the swing rod 81 and the first piston 83 to move in the same side direction. When the swing rod 81 and the first piston 83 move to one side direction, the first piston 83 pushes the hydraulic oil, and the hydraulic oil pushes the second piston 92 in the opposite side direction, driving the counterweight 3 to move. After moving, the counterweight 3 remains stationary under the action of the hydraulic oil, thereby adjusting the lateral center of gravity of the vehicle body 1, balancing the vehicle body 1, and preventing the vehicle body 1 from tipping over.
