Description

Technical Field

[0001] This utility model relates to the field of vehicles, and more specifically, to an intelligent four-wheel support mobile frame. Background Technology

[0002] In fields such as agricultural machinery and engineering construction, mobile support equipment is a key component for ensuring operational stability, requiring both "stable support" and "flexible movement." Traditional four-wheeled mobile support frames have several limitations in practical applications: First, the fixed support range leads to poor terrain adaptability. Traditional equipment often has a fixed hub structure, making it impossible to adjust the support span according to the flatness of the work site. When operating on complex terrains such as slopes or potholes, insufficient support area can easily cause the equipment to tilt, even leading to a risk of overturning. Expanding the support range requires manual replacement of extended components, which is cumbersome and inefficient. Second, movement and support are difficult to coordinate. Traditional equipment often requires fixing the support before stopping operation, or sacrificing support stability during movement. It cannot achieve a continuous operation mode of "working while slowly moving," especially in large-area work scenarios. Frequent starts, stops, and repositioning significantly increase time costs and reduce work efficiency.

[0003] Based on this, the present invention designs an intelligent four-wheel support mobile frame to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an intelligent four-wheel support mobile frame to solve the problems mentioned in the background art.

[0005] The intelligent four-wheel support mobile frame includes two sets of suspensions. Each suspension has a fixed rod rotatably connected internally. Each fixed rod has a connector I fixedly connected externally. Each connector I has a hydraulic cylinder fixedly connected externally. The output end of the hydraulic cylinder is fixedly connected to a connector II. Each suspension has a limit rod fixedly connected internally. Each limit rod has a mounting frame rotatably connected externally. Each connector II has a rotating rod internally. Both ends of the rotating rod are fixedly connected to the interior of the mounting frame. The other end of the mounting frame has a movable wheel hub.

[0006] Preferably, a traction device is fixedly connected to the left side of the left suspension, and suspension connectors are fixedly connected to the sides of the two sets of suspensions that are close to each other.

[0007] Preferably, the axis of the hydraulic cylinder forms an angle of 30°-60° with the axis of the fixed rod, and the hydraulic cylinder is located between the fixed rod and the mounting bracket.

[0008] Preferably, the limiting rod passes through the interior of the mounting frame and is rotatably engaged with it, and the rotating rod passes through the interior of the mounting frame and is fixedly connected to it.

[0009] Preferably, the movable wheel hub includes a wheel hub body and a tire. The movable wheel hub is rotatably connected to the side of the mounting frame away from the rotating rod. The tire is fixedly fitted onto the outside of the movable wheel hub. The movable wheel hub is connected to the suspension through the mounting frame.

[0010] Preferably, a wear-resistant pad is provided at the connection between the inner side wall of the mounting bracket and the limiting rod, and the wear-resistant pad is sleeved on the outside of the limiting rod.

[0011] Preferably, the length of the mounting bracket is -cm, and the mounting bracket is made of high-strength alloy steel.

[0012] Preferably, the limiting rod is used to limit the rotation range of the mounting bracket to prevent the moving hub from exceeding the set range.

[0013] Compared with existing technologies, the advantages of this utility model are: 1) In this utility model, the extension and retraction drive of the hydraulic cylinder can drive the mounting frame to rotate around the limit rod, realizing the flexible extension, retraction, and angle adjustment of the moving hubs. During operation, the front and rear sets of moving hubs can extend outward and be stably supported on the ground, greatly expanding the support area and improving the overall anti-overturning ability of the equipment, which is especially suitable for uneven terrain; at the same time, the coordinated operation of the four moving hubs can achieve slow movement while maintaining stable support, meeting the need for adjusting the position while operating, and reducing the time cost of frequent start-ups, shutdowns, and repositioning of the equipment.

[0014] 2) In this utility model, the rotational fit between the limiting rod and the mounting bracket, and the setting of the wear-resistant shims, not only ensure the stability of the mounting bracket during rotation, but also reduce frictional wear between components and extend the service life of the equipment; the angle design of the hydraulic cylinder and the fixed rod (such as 30°-60°) optimizes the power transmission efficiency and makes the extension and retraction of the moving hub more precise and controllable; while the mounting bracket made of high-strength alloy steel and the detachable suspension connector further enhance the structural strength and assembly flexibility of the equipment, making it easy to adjust the overall size or perform maintenance and replacement according to the operation requirements.

[0015] 3) In summary, this utility model achieves the comprehensive advantages of adjustable support range, convenient mobile operation, and durable structure through the telescopic structure driven by hydraulic cylinder and the stable support design of multi-component collaboration. It can not only adapt to the operation requirements of complex terrain, but also improve operation efficiency and equipment service life. It is suitable for various scenarios such as agricultural machinery and engineering equipment that require flexible movement and stable support, and has high practical value.

[0018] Example: Please refer to Figure 1-3 The intelligent four-wheel support mobile frame includes two sets of suspensions 1. Each suspension 1 has a fixed rod 2 rotatably connected inside. Each fixed rod 2 has a connecting piece 9 fixedly connected to its exterior. Each connecting piece 9 has a hydraulic cylinder 3 fixedly connected to its exterior. The output end of the hydraulic cylinder 3 is fixedly connected to a connecting piece 10. Each suspension 1 has a limit rod 4 fixedly connected inside. Each limit rod 4 has a mounting frame 6 rotatably connected to its exterior. Each connecting piece 10 has a rotating rod 5 inside. Both ends of the rotating rod 5 are fixedly connected to the interior of the mounting frame 6. The other end of the mounting frame 6 has a moving wheel hub 7. A traction device 8 is fixedly connected to the left side of the left suspension 1. Suspension connecting pieces 11 are fixedly connected to the sides of the two sets of suspensions that are close to each other. The axis of the hydraulic cylinder 3 is at a 30° angle to the axis of the fixed rod 2. The angle is 30-60°, and the hydraulic cylinder 3 is located between the fixed rod 2 and the mounting frame 6. The limiting rod 4 passes through the interior of the mounting frame 6 and rotates with it. The rotating rod 5 passes through the interior of the mounting frame 6 and is fixedly connected to it. The movable wheel hub 7 includes a wheel hub body and a tire. The movable wheel hub 7 is rotatably connected to the side of the mounting frame 6 away from the rotating rod 5. The tire is fixedly fitted on the outside of the movable wheel hub 7. The movable wheel hub 7 is connected to the suspension 1 through the mounting frame 6. A wear-resistant pad is provided at the connection between the inner side wall of the mounting frame 6 and the limiting rod 4. The wear-resistant pad is fitted on the outside of the limiting rod 4. The length of the mounting frame 6 is 30-50cm, and the mounting frame 6 is made of high-strength alloy steel. The limiting rod 4 is used to limit the rotation range of the mounting frame 6 to prevent the movable wheel hub 7 from exceeding the set range.

[0019] Hydraulic cylinder 3, acting as the drive source, is connected between the fixed rod 2 of suspension 1 and the mounting bracket 6. The axis of hydraulic cylinder 3 forms an angle of 30° to 60° with the fixed rod 2. The extension and retraction of hydraulic cylinder 3 drives the mounting bracket 6 to rotate, thereby rotating the movable wheel hub 7 and enabling flexible movement. The movable wheel hub 7 and the mounting bracket 6 are engaged by wear-resistant pads to ensure that the movable wheel hub 7 can make smooth contact with the ground during operation and maintain stable support on uneven terrain. The movable wheel hub 7 is covered with tires, which have a strong load-bearing capacity and can effectively provide ground support, especially when operating in complex terrain, significantly improving the equipment's anti-tipping ability. The two sets of suspensions 1 of the mobile frame are connected by suspension connectors 11. Connector 10 is located at the output end of the hydraulic cylinder 3 and cooperates with the rotating rod 5 between the mounting frame 6, realizing a stable connection and support between the mounting frame 6 and the mobile hub 7. The suspension connector 11 is designed to be disassembled and adjusted according to specific operational needs, facilitating equipment maintenance and reassembly, thereby improving the overall flexibility and operability of the equipment.

[0020] Working principle of this utility model: The extension and retraction of hydraulic cylinder 3 drives mounting bracket 6 to rotate around limit rod 4, thereby achieving the extension, retraction, and angle adjustment of movable hub 7. When hydraulic cylinder 3 extends, mounting bracket 6 rotates outward, causing movable hub 7 to extend outward and expand the support range; conversely, when hydraulic cylinder 3 retracts, mounting bracket 6 retracts, and movable hub 7 retracts. This hydraulically driven extension and retraction structure not only achieves flexible adjustment of the support range but also precisely controls the extension and retraction of movable hub 7, thus ensuring its stability and reliability under different working conditions. The limiting rod 4 and the mounting bracket 6 are engaged through a rotational fit, limiting the rotation range of the mounting bracket 6. The main function of the limiting rod 4 is to prevent the moving hub 7 from exceeding the set range, ensuring that the support structure is always in a safe and stable working state. Simultaneously, the limiting rod 4 and the mounting bracket 6 are also engaged through wear-resistant shims, significantly reducing frictional loss during rotation, lowering wear, and ensuring smooth movement and durability of the mounting bracket 6 during long-term use. This design not only improves the service life of the structure but also optimizes the overall system's operating efficiency.
