Description

Technical Field

[0001] This utility model relates to the field of garden machinery and equipment technology, specifically a rigid elastic suspension conversion device for connecting vehicle frame and axle. Background Technology

[0002] Landscape pruning is a common project in municipal engineering. High-altitude operations, including those using robotic arms, are frequently required in landscape pruning. When using landscape pruning vehicles, the vehicle's suspension chassis has an elastic structure. This elastic structure is not conducive to the stability of the robotic arm or manual labor during construction. Some engineering vehicles are designed with elastic lifting platforms, which is a common design. This type of lifting platform is relatively expensive, as the entire platform can be extended and rigidly fixed. However, its high cost makes it impractical for everyday use. Utility Model Content

[0003] The purpose of this invention is to provide a rigid-elastic suspension conversion device for connecting a vehicle frame and axle, which can switch between rigid and elastic structures to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A rigid elastic suspension conversion device for connecting a vehicle frame and axle includes a frame. A first crossbeam is designed on the inner left side of the upper part of the frame, a second crossbeam is designed on the right side of the upper part of the frame, and a third crossbeam is designed on the lower part of the frame. A first link assembly capable of automatic movement is designed between the first and third crossbeams, and a second link assembly is designed between the second and third crossbeams. Steel chains are respectively designed next to the first and second link assemblies. The upper part of the first link assembly is connected to the first crossbeam by a first upper link, and the end of the first upper link is provided with... The first connecting rod is connected to a first middle connecting rod. The end of the first middle connecting rod is designed to connect to a first lower connecting rod. The end of the first lower connecting rod is connected to a third crossbeam. The upper part of the second connecting rod group is connected to a second crossbeam by a second upper connecting rod. The end of the second upper connecting rod is designed to connect to a second middle connecting rod. The end of the second middle connecting rod is designed to connect to a second lower connecting rod. The end of the second lower connecting rod is connected to a third crossbeam. A lifting mechanism is designed between the middle of the first connecting rod group and the second connecting rod group. The two ends of the lifting mechanism are connected to the middle shaft position of the two connecting rod groups.

[0006] Instructions for use of this utility model patent: When the lifting mechanism extends, the top rod expands the first and second linkage groups to both sides, simultaneously causing the first upper linkage, the first middle linkage, the second upper linkage, and the second middle linkage to expand towards both sides of the frame. Ultimately, the first upper linkage and the first middle linkage are perpendicular, the first lower linkage is horizontal on the lower crossbeam, the second upper linkage and the second middle linkage are perpendicular, and the second lower linkage is horizontal on the lower crossbeam. Finally, the steel chain contracts and tightens the outward expansion force inward, so that the first, second, and third crossbeams are in a state of force balance, thus forming a rigid frame structure. Conversely, when the lifting mechanism retracts, the entire frame structure is not a rigid structure, and the first and second linkage groups can move through the shaft, thereby achieving the switching between elasticity and rigidity.

[0007] The advantages of this utility model are that by making the vehicle rigid during operation, the attachments are stable, and the transportation between sites is safe and comfortable. This structure can easily complete the rigid elastic conversion of the vehicle axle and frame connection, realize multiple functions, and also save the cost of the lifting platform.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] A rigid elastic suspension conversion device for connecting a vehicle frame and axle includes a frame 1. A first crossbeam 2 is designed on the inner left side of the upper part of the frame 1. A second crossbeam 21 is designed on the right side of the upper part of the frame 1.

A second link assembly 5 is designed between the second crossbeam 21 and the third crossbeam 3. Steel chains 31 are respectively designed next to the first link assembly 4 and the second link assembly 5. The upper part of the first link assembly 4 is connected to the first crossbeam 2 by a first upper link 41. The end of the first upper link 41 is designed with... A first middle connecting rod 42 is connected to the shaft. The end of the first middle connecting rod 42 is designed to be connected to the first lower connecting rod 43. The end of the first lower connecting rod 43 is connected to the third crossbeam 3. The upper part of the second connecting rod group 5 is connected to the second crossbeam 21 by the second upper connecting rod 51. The end of the second upper connecting rod 51 is designed to be connected to the second middle connecting rod 52. The end of the second middle connecting rod 52 is designed to be connected to the second lower connecting rod 53. The end of the second lower connecting rod 53 is connected to the third crossbeam 3. A lifting mechanism 6 is designed between the middle of the first connecting rod group 4 and the second connecting rod group 5. The two ends of the lifting mechanism 6 are connected to the middle shaft position of the two connecting rod groups.

[0016] Instructions for use of this utility model patent: When the lifting mechanism extends, the top rod expands to both sides, opening the first link group 4 and the second link group 5. At the same time, the first upper link 41, the first middle link 42, the second upper link 51, and the second middle link 52 expand to both sides of the frame. Ultimately, the first upper link 41 and the first middle link 42 are perpendicular, the first lower link 43 is horizontal on the lower crossbeam 3, the second upper link 51 and the second middle link 52 are perpendicular, and the second lower link 53 is horizontal on the lower crossbeam 3. Finally, the steel chain 31 contracts and tightens the outward expansion force inward, so that the first crossbeam, the second crossbeam, and the third crossbeam are in a state of force balance, thus forming a rigid frame structure. Conversely, when the lifting mechanism retracts, the entire frame structure is not a rigid structure. The first link group 4 and the second link group 5 can move through the shaft, thus achieving the switching between elasticity and rigidity.
