Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] The first aspect of this application provides a loading boom structure, which is applied to a loader and is mainly used for power transmission and load bearing. The loading boom structure in this embodiment, through its innovative structural design, can improve the structural strength of the loading boom and facilitate the processing and manufacturing of the loading boom structure.

[0032] In related technologies, loaders are often used in industrial settings to move and load heavy objects. In the structure of a loader, the boom structure is one of the core structures. The boom of a loader usually bears a large force during use, so the boom structure of the loader needs to have sufficient structural strength.

[0033] Existing boom structures are typically formed by welding seamless steel pipes or square tubes. Among existing boom structures, there are also boom structures formed by welding two U-shaped bending plates together. When processing the U-shaped bending plates, the forming requirements of the bending plates are high, and a bevel needs to be made at the welding position to facilitate the connection of the two bending plates. Therefore, the processing accuracy requirements are high. Moreover, during use, the welded joint of the two bending plates is prone to cracking under long-term stress, which is not conducive to the structural stability of the boom structure of the loader and is also inconvenient for the processing and manufacturing of the boom structure of the loader.

[0034] In view of this, in order to overcome the shortcomings of the related technology, the loading boom structure of this embodiment combines... Figures 1 to 4 As shown, the overall design includes a boom body 1, and a first connecting arm 2 and a second connecting arm 3 connected to the boom body 1.

[0035] The boom body 1 includes a first plate 101, a second plate 102, and a third plate 103 connected together. The first plate 101 and the second plate 102 form an angle between them. The third plate 103 is connected between the first plate 101 and the second plate 102, and the first plate 101, the second plate 102, and the third plate 103 form a triangular cavity.

[0036] The first connecting arm 2 is disposed on both sides of the boom body 1, and the second connecting arm 3 is disposed on the top of the boom body 1. Both the first connecting arm 2 and the second connecting arm 3 are provided with connecting holes 4 for connecting to an external carrier.

[0037] At this time, as set up as above, the boom body 1 is formed by connecting the first plate 101, the second plate 102 and the third plate 103, and the boom body 1 has a triangular cavity, which improves the structural strength of the boom body 1. The structure is simple, eliminates the plate bending process, is easy to process, and has good structural strength. At the same time, it can reduce the volume of the boom structure, reduce the field of vision obstructed by the boom structure, and broaden the driver's field of vision when the boom structure is used, thereby improving the structural strength of the loader boom structure and facilitating the processing and manufacturing of the boom structure.

[0038] Based on the above general introduction, specifically, the loader boom structure in this embodiment is usually connected to the loader's loading structure (such as the bucket) and the loader's power system (such as the hydraulic system), so as to transmit power and bear weight.

[0039] In actual implementation, the above-mentioned loader boom structure is usually connected to related structures using a pin connection. Of course, in addition to the pin connection, the above-mentioned loader boom structure can also be connected to related structures in existing loaders using connection methods (such as articulation). This will not be elaborated further here.

[0040] The hypotenuse of the triangular cavity formed by the first plate 101, the second plate 102, and the third plate 103 is located below the boom body 1, meaning the second plate 102 constitutes the hypotenuse of the triangular cavity. This reduces the obstruction area of ​​the structure below the boom body 1, thus improving the driver's field of vision.

[0041] Continue to combine Figures 1 to 4As shown, in some exemplary embodiments, this embodiment may, for example, include a first connecting arm 2 comprising a first arm plate 201 and a second arm plate 202 disposed on both sides of the boom body 1.

[0042] The first boom plate 201 and the second boom plate 202 are provided with connection holes 4 at both ends, and the first boom plate 201 and the second boom plate 202 are provided with connection holes 4 located below the boom body 1 in the middle.

[0043] It is understandable that by making the first connecting arm 2 include a first arm plate 201 and a second arm plate 202 respectively disposed on both sides of the boom body 1, and forming the connecting hole 4 at the ends and middle of the first arm plate 201 and the second arm plate 202, the structure is simple, easy to process, and facilitates the connection and assembly of the loader boom structure with the external carrier.

[0044] In specific implementation, the first boom plate 201 and the second boom plate 202 are both integrally formed plate structures, and the first boom plate 201 and the second boom plate 202 can respectively cover the two ends of the boom body 1 to improve the connection strength between the boom body 1 and the first boom plate 201 and the second boom plate 202.

[0045] The specific shape design of the first boom plate 201 and the second boom plate 202 is related to factors such as the loader's loading capacity, drive power, and size. In actual implementation, it is necessary to make corresponding settings according to the loader's design requirements.

[0046] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, provide a first stiffener 5 and a second stiffener 6 spaced apart between the first connecting arm 2 and the boom body 1.

[0047] The first stiffener 5 and the second stiffener 6 are connected at both ends to the first arm plate 201 and the second arm plate 202 respectively, and the tops of the first stiffener 5 and the second stiffener 6 are connected to the second plate 102.

[0048] It is understandable that by setting the first stiffener 5 and the second stiffener 6, the connection strength between the boom body 1 and the first connecting arm 2 can be improved through the synergistic effect of the first stiffener 5 and the second stiffener 6, and the structural strength of the boom body 1 can be strengthened. In addition, two force transmission paths are constructed on the loading boom structure, which helps to disperse the force borne by the loading boom structure during use and is conducive to design and implementation.

[0049] In specific implementation, the first stiffener 5 and the second stiffener 6 are supported on the side of the second plate 102 near the included angle, and both the first stiffener 5 and the second stiffener 6 are U-shaped, with the opening direction of the first stiffener 5 and the second stiffener 6 facing downward.

[0050] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, include a second connecting arm 3 comprising a third arm plate 301 and a fourth arm plate 302 spaced apart at the top of the boom body 1.

[0051] The bottom of the third arm plate 301 and the fourth arm plate 302 are both connected to the first plate 101, and the bottom of the third arm plate 301 and the fourth arm plate 302 extend toward the second plate 102 and are connected to the third plate 103. The top of the third arm plate 301 and the fourth arm plate 302 are both provided with connecting holes 4.

[0052] It is understandable that by making the second connecting arm 3 include a third arm plate 301 and a fourth arm plate 302, and connecting the bottom of the third arm plate 301 and the fourth arm plate 302 to the first plate body 101 and the third plate body 103, and arranging the connecting holes 4 on the top of the third arm plate 301 and the fourth arm plate 302, it is convenient to connect with the external carrier, and the structural strength of the loading boom structure is further improved. The structure is simple, easy to process and manufacture, and conducive to design and implementation.

[0053] In specific implementation, the third arm plate 301 and the fourth arm plate 302 can be plate-shaped structures, and the bottom of the third arm plate 301 and the fourth arm plate 302 is provided with a connecting groove corresponding to the connection position of the first plate body 101 and the third plate body 103. The shape of the connecting groove corresponds to the shape of the connection point of the first plate body 101 and the third plate body 103, so as to connect the bottom of the third arm plate 301 and the fourth arm plate 302 to the first plate body 101 and the third plate body 103.

[0054] In addition, the tops of the connecting holes 4 of the third boom plate 301 and the fourth boom plate 302 are arranged in an arc shape to facilitate the cooperation of the third boom plate 301 and the fourth boom plate 302 with the relevant structures on the loader.

[0055] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, provide a third rib plate 7 connecting the third arm plate 301 and the first connecting arm 2 on the same side, and a fourth rib plate 8 connecting the fourth arm plate 302 and the first connecting arm 2 on the same side, and a fourth rib plate 8 connecting the fourth arm plate 302 and the first connecting arm 2 on the same side, respectively.

[0056] It is understandable that by setting the third stiffener 7 and the fourth stiffener 8 on the third arm plate 301 and the fourth arm plate 302, the structure of the third arm plate 301 and the fourth arm plate 302 is strengthened, the connection strength of the third arm plate 301 and the fourth arm plate 302 is improved, and a new force transmission channel is constructed between the third arm plate 301 and the fourth arm plate 302 and the first plate 101, which facilitates the distribution of the forces borne by the third arm plate 301 and the fourth arm plate 302 during use.

[0057] In practical implementation, both the third stiffener 7 and the fourth stiffener 8 are inclined relative to the first plate 101, and the extending directions of both the third stiffener 7 and the fourth stiffener 8 can pass through the axis of the connecting hole 4 provided on the corresponding third arm plate 301 and fourth arm plate 302. The third stiffener 7 and the fourth stiffener 8 can, for example, be triangular stiffeners.

[0058] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, provide a reinforcing patch 9 on each connecting hole 4, and the reinforcing patch 9 shall have a connecting through hole 901 corresponding to the connecting hole 4, and the connecting through hole 901 shall be coaxially arranged with the connecting hole 4.

[0059] It is understandable that by strengthening the setting of patch 9, the structural strength at the connection hole 4 position can be improved, which in turn can enhance the connection strength when the boom structure is connected to the external carrier, facilitate processing and manufacturing, and facilitate design and implementation.

[0060] In specific implementation, the reinforcing patches 9 are set on both sides of the connecting holes 4. In addition to being connected to the corresponding connecting holes 4, the reinforcing patches 9 can also be integrally formed with the corresponding first arm plate 201, second arm plate 202, third arm plate 301 and fourth arm plate 302.

[0061] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, provide a fifth rib plate 10 inside the boom body 1, the fifth rib plate 10 being conformally arranged to the cavity of the boom body 1.

[0062] It is understandable that by setting the fifth stiffener 10, the structure is strengthened in the cavity of the boom body 1, and the fifth stiffener 10 is set to conform to the shape of the cavity, so that the force on the boom body 1 can be transmitted and dispersed through the fifth stiffener 10, thereby further improving the structural strength of the boom body 1 and facilitating design and implementation.

[0063] In specific implementation, the above-mentioned fifth stiffener 10 can be, for example, multiple fifth stiffeners 10 spaced apart in the cavity of the boom body 1, and the fifth stiffener 10 can be welded to the boom body 1.

[0064] Continue to combine Figures 1 to 4As shown, in some exemplary embodiments, this embodiment may, for example, have the edge of the fifth stiffener 10 correspondingly connected to the first plate 101, the second plate 102, and the third plate 103.

[0065] It is understandable that by connecting the edge of the fifth stiffener 10 to the first plate 101, the second plate 102 and the third plate 103 respectively, the structural stability of the fifth stiffener 10 in the cavity of the boom body 1 is improved, and the connection stability between the fifth stiffener 10 and the boom body 1 is improved, which facilitates design and implementation.

[0066] In practice, the edges of the fifth stiffener 10 are welded to the first plate 101, the second plate 102 and the third plate 103 respectively, and the fifth stiffener 10 is arranged in a triangular shape.

[0067] Continue to combine Figures 1 to 4 As shown, in some exemplary embodiments, this embodiment may, for example, provide weight-reducing holes 11 on the fifth stiffener 10.

[0068] It is understandable that by setting the weight reduction hole 11, the weight of the fifth stiffener 10 can be reduced, which helps to reduce the weight increase caused by the addition of the fifth stiffener 10 while ensuring the structural strength of the boom body 1. Moreover, the reasonable setting of the weight reduction hole 11 can further optimize the force transmission of the fifth stiffener 10, which helps to improve the structural strength of the boom body 1.

[0069] In practical implementation, the shape of the above weight reduction hole 11 can be, for example, a round hole, a square hole, an elliptical hole, a long strip hole or a racetrack-shaped hole, which is related to the material, size and setting position of the reinforcing rib. In actual implementation, it is necessary to set it accordingly according to the design requirements of the loading boom.

[0070] It is worth noting that, regarding the loading boom structure of this embodiment, based on the above exemplary implementations, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 4 As shown, it may include, for example, a boom body 1, and a first connecting arm 2 and a second connecting arm 3 connected to the boom body 1.

[0071] The boom body 1 includes a first plate 101, a second plate 102 and a third plate 103 connected together. The first plate 101 and the second plate 102 form an angle between them. The third plate 103 is connected between the first plate 101 and the second plate 102. The first plate 101, the second plate 102 and the third plate 103 form a triangular cavity.

[0072] The boom body 1 has a fifth stiffening plate 10 inside its cavity. The fifth stiffening plate 10 has a weight reduction hole 11. The fifth stiffening plate 10 is shaped to fit the cavity of the boom body 1. Each edge of the fifth stiffening plate 10 is connected to the first plate 101, the second plate 102 and the third plate 103.

[0073] The first connecting arm 2 includes a first arm plate 201 and a second arm plate 202 respectively disposed on both sides of the boom body 1. Both ends of the first arm plate 201 and the second arm plate 202 are provided with connecting holes 4, and the middle of the first arm plate 201 and the second arm plate 202 is also provided with connecting holes 4 located below the boom body 1. A first stiffening plate 5 and a second stiffening plate 6 are provided between the first arm plate 201 and the second arm plate 202 at intervals. The tops of the first stiffening plate 5 and the second stiffening plate 6 are both connected to the second plate 102.

[0074] The second connecting arm 3 includes a third arm plate 301 and a fourth arm plate 302 spaced apart on the top of the boom body 1. The bottoms of the third arm plate 301 and the fourth arm plate 302 are both connected to the first plate 101. The bottoms of the third arm plate 301 and the fourth arm plate 302 also extend towards the second plate 102 and connect to the third plate 103. The tops of the third arm plate 301 and the fourth arm plate 302 are each provided with a connecting hole 4. A third stiffening plate 7 and a fourth stiffening plate 8 are respectively provided between the third arm plate 301 and the fourth arm plate 302 and the first connecting arm 2 on the same side.
