Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, specifically to a multi-functional boom for excavators. Background Technology

[0002] Excavators are widely used in the field of construction machinery and are one of the essential products for engineering construction. They have a wide range of operations and complex working conditions. There are many special working conditions during use, which require the use of corresponding special working devices. For example, in the case of material handling at the port, the role of traditional excavators is relatively limited, and a special material handling machine is needed to meet the working conditions.

[0003] Traditional excavators mainly consist of a boom, stick, bucket, and corresponding hydraulic cylinders, which drive the digging action. When a traditional excavator's stick is equipped with a grab for material handling, the lifting height is limited, making it difficult to reach the required grab height in actual working conditions. Furthermore, the rear lugs cannot be adapted to the boom when reversed. Therefore, when material handling is required, a custom-made grabbing device must be developed to fit the existing excavator. However, this custom-made grabbing device cannot be used for digging operations, increasing production and operating costs. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-functional boom and excavator to solve the problem mentioned in the background art that the traditional boom cannot simultaneously adapt to both the grab and the bucket due to the limited lifting height and the limited rear lug structure, and that a corresponding material grabbing device needs to be customized to adapt to the original excavator.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional boom, comprising: a boom body, wherein the boom body is provided with a shaft for connecting to a bucket or a grab, a second shaft for connecting a bucket cylinder connecting rod near the first shaft, a third shaft at the other end of the boom body, a rear ear plate near the third shaft, and an upper ear plate for mounting the bucket cylinder; During excavation operations, the three axes are hinged to the boom, and the rear ear plate is hinged to the boom cylinder. During material handling, the rear ear plate is hinged to the boom, and the three shafts are hinged to the boom cylinder; The three axes and the rear ear plate are all equipped with bearing structures of the same size as hinge components.

[0006] Preferably, the three axes and the rear ear plate on the stick body are provided with curved plates and reinforcing plates; The reinforcing plates are fixed on both sides of the curved plate and are respectively set in the three shafts and the rear ear plate in the body of the stick to form open mounting positions, and the bearing structure is installed on both sets of mounting positions.

[0007] Preferably, the bearing structure consists of two sets of symmetrical bearing bodies and pins, and the bearing bodies are coaxially mounted on the three axes and the rear ear plate of the boom body; When the external structure is connected to the bearing seat structure, it includes being installed on the outside of the bearing seat body and being installed between the bearing seat body, and is hinged to the external structure and the bearing seat body through the pin. When the external structure is installed between the bearing seat bodies, the pin is limited on both sides by baffles.

[0008] Preferably, the pin is connected to the bearing body via a bearing.

[0009] Preferably, a dust seal is installed on the inner and / or outer side of the bearing.

[0010] Preferably, the bearing seat body has a threaded hole, and the baffle is fixed to the bearing seat body by screws.

[0011] Preferably, the screws are distributed in an array at equal intervals around the axis of the baffle.

[0012] An excavator equipped with the aforementioned multi-functional boom.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention is based on the existing traditional stick. On this basis, the rear lug plate is removed, and the same type of bearing seat as the three axes of the stick is opened on the stick. The two bearing seats are of uniform size. With the help of the curved plate and the reinforcing plate, an open mounting position that can accommodate the hydraulic cylinder connecting lug is formed. This allows for both forward and reverse mounting and can be used with either the bucket or the grab. This solves the problem in the prior art that the traditional stick cannot be adapted to both the grab and the bucket at the same time due to the limited lifting height and the limited structure of the rear lug plate. It also solves the problem .... It also solves the problem that the corresponding grabbing device needs to be customized to adapt to the original excavator. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0018] Please see Figures 1-8 A multi-functional pole, combining Figure 1 and Figure 2 As shown, the boom body 1 is provided with a first shaft 2 for connecting to the bucket or grab, a second shaft 3 for connecting the bucket cylinder connecting rod near the first shaft 2, a third shaft 4 at the other end of the boom body 1, a rear ear plate 5 near the third shaft 4, and an upper ear plate 6 for installing the bucket cylinder.

[0019] like Figure 3 As shown, the three shafts 4 and the rear ear plate 5 on the stick body 1 are reinforced with plates 7 welded to both sides of the bent plate 14 and respectively set in the stick body 1 to form open mounting positions. Both mounting positions are equipped with bearing structures.

[0020] like Figure 4 As shown, the bearing structure consists of two sets of symmetrical bearing bodies 8 and pins 9. The bearing bodies 8 are coaxially and symmetrically fixed to the three shafts 4 and the rear ear plate 5 in various mounting positions on the boom body 1; and the bearing bodies 8 installed on the three shafts 4 and the rear ear plate 5 are of the same size. The pins 9 are connected to the bearing bodies 8 by bearings 10, and dust rings 11 are installed on both the inner and outer sides of the bearings 10.

[0021] It should be noted that: such as Figure 5 As shown, during excavation operations, the bucket is hinged to the first shaft 2 of the boom body 1, the second shaft 3 is hinged to the first connecting rod, the bucket is hinged to the second connecting rod, the first connecting rod and the second connecting rod are hinged together to the bucket cylinder, the other end of the bucket cylinder is hinged to the upper ear plate 6, the bearing structure of the third shaft 4 is hinged to the excavator boom, and the bearing structure of the rear ear plate 5 is hinged to the excavator boom cylinder.

[0022] like Figure 8 As shown, during material handling, a gripper with a clamping drive structure is installed on shaft 2. The rear ear plate 5 is hinged to the boom, and the shaft seat structure of the third shaft 4 is hinged to the boom cylinder. The specific gripper dimensions and models can be appropriately selected by those skilled in the art based on the excavator's power and actual needs; detailed descriptions are omitted here.

[0023] like Figure 6 As shown, when the excavator boom cylinder is installed with the bearing body 8, the cylinder connecting lug is installed between the two bearing bodies 8. The cylinder connecting lug and the bearing body 8 are hinged by a pin 9 passing through it. The pin 9 is limited on both sides by baffles 12. The baffles 12 are fixed in the threaded holes on the bearing body 8 by screws 13 arranged in an evenly spaced array.
