Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to a device that can maintain the self-balancing function of an object. Background Technology

[0002] Construction machinery is widely used in various material handling and excavation operations in construction, mining, logistics, and other fields. It is often equipped with attachments such as buckets and grabs to complete different operational tasks. During operation, in order to ensure that the relative posture of the attachments to the ground remains unchanged, the operator usually needs to constantly adjust the angle of the boom or attachments to achieve accurate material handling and control. This posture control is particularly critical in working conditions such as loading, excavation, and stacking. Especially in operation scenarios where the attachments need to be kept horizontal, the realization of self-balancing function is of great significance to equipment performance and operating efficiency.

[0003] Traditional equipment requires operators to use both hands to operate handles to adjust and control attachments, which is cumbersome. In actual operation, operators need to make continuous and precise adjustments based on the equipment's movement and ground conditions. This method requires high skill levels and reaction speed from the operator, and also increases physical exertion and labor intensity. Continuous long-term operation can easily lead to operator fatigue, thereby affecting work safety and efficiency. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device that can maintain self-balancing functionality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for maintaining the self-balancing function of attachments includes a fixed device, an upper boom, a lower boom, and a boom link. One end of the upper boom is rotatably connected to the fixed device via a second hinge point, and the other end is rotatably connected to the boom link via a fourth hinge point. One end of the lower boom is rotatably connected to the fixed device via a first hinge point, and the other end is rotatably connected to the boom link via a third hinge point. The first hinge point, second hinge point, third hinge point, and fourth hinge point are sequentially connected to form a parallelogram structure. An attachment is installed on one side of the boom link.

[0007] As a further embodiment of this utility model, both the upper boom and the lower boom are plate structures, and they are hinged to each other through boom connecting rods to form a linkage structure.

[0008] As a further embodiment of this utility model, the attachment is a shovel bucket or a grab bucket.

[0009] As a further embodiment of this utility model, the boom connecting rod is a rigid rod, and round holes are provided at both ends for inserting pins to form a rotating connection.

[0010] As a further embodiment of this utility model, the line connecting the first hinge point and the second hinge point is always parallel to the line connecting the third hinge point and the fourth hinge point, forming opposite sides of a parallelogram.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This device, which maintains the self-balancing function of the attachments, forms a base structure with the upper and lower booms through a fixing device. Four hinge points are set between the upper boom and the boom link, and between the lower boom and the boom link, so that the four hinge points form a parallelogram. During the boom lifting and lowering process, the attachments on one side of the boom link always move along a specific posture without tilting or rotating, ensuring the consistency of the working angle. This can reduce the workload of the operators, reduce restrictions on personnel, optimize the cumbersome operation process, improve work efficiency, shorten work time, improve safety, and lower the operation threshold for operators.

[0019] Reference Figures 1-2 A device for maintaining the self-balancing function of attachments includes a fixed device 1, an upper boom 2, a lower boom 3, and a boom link 4. One end of the upper boom 2 is rotatably connected to the fixed device 1 via a second hinge point 201, and the other end is rotatably connected to the boom link 4 via a fourth hinge point 401. One end of the lower boom 3 is rotatably connected to the fixed device 1 via a first hinge point 101, and the other end is rotatably connected to the boom link 4 via a third hinge point 301. The first hinge point 101, the second hinge point 201, the third hinge point 301, and the fourth hinge point 401 are sequentially connected to form a parallelogram structure. An attachment 5 is installed on one side of the boom link 4. The upper boom 2, lower boom 3, and boom link 4 form a parallelogram structure with four hinge points. During the lifting and lowering of the upper boom 2 and lower boom 3, the opposite sides of the quadrilateral remain parallel, thereby driving the attachment 5 on one side of the boom link 4 to maintain a constant posture relative to the ground. No manual intervention is required for the angle of the attachment 5. The attachment 5 can automatically maintain a horizontal position during the boom movement, achieving self-balancing, reducing the operator's workload, and improving the accuracy of operation. The fixing device 1 is used to support and connect the upper boom 2 and lower boom 3. It can be a bracket, frame, or base structure installed on the equipment body to provide a stable hinge foundation, allowing the entire four-bar linkage to be adjusted in posture on its foundation.

[0020] In this embodiment, both the upper boom 2 and the lower boom 3 are plate structures, and they are hinged to each other through the boom link 4 to form a linkage structure. The upper boom 2 and the lower boom 3, which are plate structures, are connected by the rigid boom link 4 to form a complete mechanical quadrilateral mechanism.

[0021] In this embodiment, the attachment 5 is a bucket, grab bucket, or other working tool. The attachment 5, such as a bucket or grab bucket, serves as a connecting end effector and can be installed with the boom linkage 4, which expands the versatility and adaptability of the device and is suitable for various engineering machinery scenarios, such as loading, handling, and excavation.

[0022] In this embodiment, the boom connecting rod 4 is a rigid rod, and round holes are provided at both ends for inserting pins to form a rotating connection. The two ends of the boom connecting rod 4 are connected to the pins through round holes to form a rotating pair, which can maintain the quadrilateral configuration as the boom rotates, ensuring the flexible rotation and force balance of the structure, facilitating maintenance and replacement of parts, and improving reliability.

[0023] In this embodiment, the line connecting the first hinge point 101 and the second hinge point 201 and the line connecting the third hinge point 301 and the fourth hinge point 401 are always parallel, forming opposite sides of a parallelogram. The opposite sides in the parallelogram mechanism are always parallel, ensuring that the geometric relationship of the mechanism remains unchanged at any angle. The attachment 5 maintains its posture without tilting during the lifting and lowering of the boom, and has good dynamic balance characteristics and motion continuity.

[0024] Working Principle: In use, this device forms a base structure with the upper boom 2 and lower boom 4 via the fixed device 1. A first hinge point 101, a second hinge point 201, a third hinge point 301, and a fourth hinge point 401 are respectively set between the upper boom 2 and the boom link 4, and between the lower boom 3 and the boom link 4, forming a parallelogram. During boom lifting and lowering, the attachment 5 on one side of the boom link 3 always moves along a specific posture without tilting or rotating, ensuring consistent working angles. This movement method does not require electronic sensors or additional angle control systems; the attachment 5 can achieve self-balancing solely through a purely mechanical structure, thus improving the stability and practicality of the device. The device is applied to skid steer loaders, loaders, excavators, or other engineering machinery with boom structures to maintain the stability of the attachment 5 during operation. It is suitable for various engineering machinery; installing this structure on the boom mechanism enables the attachment 5 to automatically maintain its posture.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
