[0032] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0034] Combine the following Figure 1 to Figure 2 The additional counterweight support device of the utility model is described, which is used to connect the additional counterweight and the work machine turntable, wherein, generally speaking, the side of the work machine turntable connected to the attachment is the head side, and the side opposite to the head side is the tail side.

[0035] like Figure 1 As shown, the first embodiment of the utility model is to provide an additional counterweight support device for connecting the additional counterweight and the operating machine turntable 10, including additional counterweight brackets 20 arranged in pairs, the first end of each additional counterweight bracket 20 is used to connect with the additional counterweight, and the second end is used to connect with the operating machine turntable 10. The entire additional counterweight support device is arranged in a split type, which can effectively connect the additional counterweight and the operating machine turntable 10. Compared with the integral type, the amount of steel used is reduced, the installation is convenient, and the overall cost can be reduced. Among them, the additional counterweight bracket 20 has at least one triangular structure inside, which ensures that the additional counterweight bracket has sufficient strength and stability, so that the additional counterweight assembly is not easy to shake or fall off during operation.

[0036] It should be understood that the additional counterweight support frame 20 can be designed as a frame structure composed of rods or plates, wherein the rods or plates are connected to each other by welding, riveting or bolting to form an internal support with a triangular structure. The first end of the additional counterweight support frame can be provided with a connecting piece, such as a hook, a slot or a bolt hole, for connecting with the additional counterweight; the second end can also be provided with a corresponding connecting piece for connecting with the work machine turntable 10.

[0037] In a feasible embodiment of the present invention, the additional counterweight support frame 20 includes a plurality of support rods, one end of each of the plurality of support rods is connected to the first end, the other ends of each of the plurality of support rods are arranged toward the second end, and an angle is formed between each two adjacent support rods. This design not only increases the stability of the additional counterweight support frame 20, but also can adjust the angle according to actual needs to adapt to different working environments and operating requirements. At least one support rod is connected to the top of the tail side of the operating machine turntable 10, ensuring a stable connection between the additional counterweight support frame 20 and the operating machine turntable 10. Among them, one end of the plurality of support rods can be welded to the first end, or can be connected to the first end in other ways, as long as a fixed connection can be achieved to ensure structural stability.

[0038] At the same time, at least one support rod contacts the bottom of the rear side of the working machine turntable 10 to form a support for the additional counterweight support frame 20 and the working machine turntable 10, increase the contact area between the additional counterweight support frame 20 and the working machine turntable 10, and further improve the stability of the additional counterweight support frame 20.

[0039] In summary, the plurality of support rods constitute the main structure of the additional counterweight support frame 20 , and the plurality of support rods form a pyramid structure to ensure the stability of the additional counterweight support frame 20 .

[0040] In a feasible embodiment of the utility model, the additional counterweight support frame 20 also includes a first connecting member 21, which is arranged at the first end and plays a role of connection and support. The first connecting member 21 is used to be hinged with the additional counterweight, and the main function of the first connecting member 21 is to be hinged with the additional counterweight. Hinge is a connection method that allows two parts to rotate relative to each other within a certain range. Therefore, through the first connecting member 21, the additional counterweight can be flexibly connected to the additional counterweight support frame 20, while allowing a certain degree of rotation freedom during operation.

[0041] The first connecting member 21 can be set in a plate shape, and a through hole is opened on the first connecting member 21. When the first connecting member 21 is connected to the additional counterweight, a pin can be used to pass through the through hole, which is convenient for installation. After adding the first connecting member 21, the additional counterweight support frame 20 can not only provide a stable support, but also can be flexibly connected to the additional counterweight by a hinged manner. This design enables the support frame to adapt to different working environments and operating requirements, and improve the stability and work efficiency of the operating machinery.

[0042] In a feasible embodiment of the utility model, a plurality of abdominal tubes 22 are provided between two adjacent support rods, and the abdominal tubes 22 and the support rods connected thereto form a triangular structure. The provision of the abdominal tubes 22 can significantly enhance the connection strength between adjacent support rods, making the entire structure of the additional counterweight support frame 20 more stable and durable. By adding the abdominal tubes 22, the additional counterweight support frame 20 can better disperse and resist external forces when bearing the pressure of the additional counterweight, thereby improving the overall stability. In complex or harsh working environments, the additional counterweight support frame 20 may be affected by various external forces. The provision of the abdominal tubes 22 can effectively prevent unnecessary deformation or distortion of the support rods.

[0043] like Figure 2 As shown, in a feasible embodiment of the utility model, the support rods include four, namely the first rod 23, the second rod 24, the third rod 25 and the fourth rod 26, wherein the plane formed by the first rod 23 and the second rod 24 is the first plane, and the first plane can be set as the XY plane; the plane formed by the third rod 25 and the fourth rod 26 is the second plane, and the angle between the first plane and the second plane is 30-45 degrees, that is, the second plane is inclined 30-45 degrees relative to the XY plane, so as to achieve a balance between the stability and flexibility of the additional counterweight support frame 20. Too small an angle may lead to an insufficiently stable structure, while too large an angle may affect the overall stability and operating efficiency of the support frame. By adjusting the angle between the first plane and the second plane, the additional counterweight support frame 20 can better adapt to different working environments and operating requirements. This design enables the additional counterweight support frame 20 to maintain sufficient stability while bearing the additional counterweight, and prevent tilting or shaking due to external forces.

[0044] In a feasible embodiment of the utility model, the additional counterweight support frame 20 also includes a second connecting member 28, which is arranged at the end of the first rod 23 and the third rod 25 facing the working machine turntable 10. The second connecting member 28 is used to be hinged with the working machine turntable 10. The hinged connection allows a certain degree of rotational freedom between the additional counterweight support frame 20 and the working machine turntable 10, which means that the additional counterweight support frame 20 can adjust the angle as needed to adapt to different working environments and requirements. Through the hinged connection between the second connecting member 28 and the working machine turntable 10, the additional counterweight support frame 20 can be more firmly installed on the working machine turntable 10 while maintaining a certain degree of flexibility. This design can not only ensure the stability of the additional counterweight support frame 20 when bearing the additional counterweight, but also adapt to various changes in the working process.

[0045] like Figure 2As shown, in a feasible embodiment of the utility model, the additional counterweight support frame 20 also includes a support plate 27, which is arranged at the end of the second rod 24 and the fourth rod 26 facing the working machine turntable 10, and the support plate 27 is used to contact the working machine turntable 10. The support plate 27 is located at the contact point between the additional counterweight support frame 20 and the working machine turntable 10, and plays a key supporting and stabilizing role. The main function of the support plate 27 is to contact the working machine turntable 10. By adding the support plate 27, the contact area between the additional counterweight support frame 20 and the working machine turntable 10 is increased, thereby improving the overall stability. In addition, the support plate 27 can also disperse the pressure of the additional counterweight support frame 20 on the working machine turntable 10, reduce the concentrated stress of the stress point of the working machine turntable 10, and help to extend the service life of the working machine turntable 10. The addition of the support plate 27 makes the connection between the additional counterweight support frame 20 and the working machine turntable 10 more stable. By increasing the contact area and dispersing the pressure, the support plate 27 significantly improves the stability of the additional counterweight support frame 20 when bearing the additional counterweight. This design helps to reduce the shaking and tilting of the additional counterweight support frame 20 during operation, thereby improving operation efficiency and safety.

[0046] In a feasible embodiment of the utility model, the length of the second rod 24 is greater than the first rod 23, and the length of the fourth rod 26 is greater than the third rod 25. Such a structural setting is to optimize the overall stability and load-bearing capacity of the additional counterweight support frame 20. Longer rods can provide a larger support range and stronger structural rigidity, which helps to better disperse and withstand the pressure of the additional counterweight. A reinforcing rod 29 is arranged between the end of the first rod 23 facing the working machine turntable 10 and the second rod 24, and between the end of the third rod 25 facing the working machine turntable 10 and the fourth rod 26. The main function of the reinforcing rod 29 is to enhance the structural strength of the additional counterweight support frame 20 at these key connection points. Since these positions are the key areas where the additional counterweight support frame 20 contacts and supports the working machine turntable 10, the addition of the reinforcing rod 29 can significantly improve the torsion and bending resistance of the additional counterweight support frame 20 in these areas, and prevent deformation or damage due to external forces.

[0047] The additional counterweight support device provided by the utility model has a first rod 23 and a second rod 24 connected to the first end and slotted, the first rod 23 and the second rod 24 are in the XY plane, and the first connecting member 21 is inserted into the slot of the first end. The third rod 25 and the fourth rod 26 are in a plane inclined by 30 degrees to 45 degrees from the XY plane and are connected to the first end. The second connecting member 28 is welded to the end of the first rod 23 and the third rod 25 facing the working machine turntable 10, and the support plate 27 is welded to the end of the second rod 24 and the fourth rod 26 facing the working machine turntable 10. The second connecting member 28 is connected to the tail of the working machine turntable 10 through a pin shaft, and the support plate 27 can be directly supported to the tail of the working machine turntable 10. The belly tube 22 can be composed of 12 oblique belly tubes and 4 straight belly tubes, which support the first rod 23, the second rod 24, the third rod 25 and the fourth rod 26 to form a stable truss structure.

[0048] The second aspect of the utility model is to provide a counterweight assembly, including a counterweight tray 30, a pair of counterweight pull plates 50, a pair of lifting cylinders 60 and an additional counterweight support device as described in any of the above embodiments, wherein an additional counterweight 40 is arranged on the top of the counterweight tray 30, and the counterweight tray 30 provides a stable platform for carrying the additional counterweight 40 to ensure that the additional counterweight 40 can remain stable during operation. A pair of counterweight pull plates 50 are respectively connected to the two sides of the counterweight tray 30, which helps to maintain the balance and stability of the counterweight system during the lifting process. The bottom end of each lifting cylinder 60 is connected to the counterweight pull plate 50; the additional counterweight support frame 20 in the additional counterweight support device is connected to the top of the lifting cylinder 60 to form a stable support structure for bearing the force transmitted from the lifting cylinder 60 and the weight of the additional counterweight 40.

[0049] The working principle of the counterweight assembly provided by the utility model is that when the additional counterweight 40 needs to be lifted, the lifting cylinder 60 starts to work, generating thrust to lift the counterweight pull plate 50, the counterweight tray 30 and the additional counterweight 40 together. In this process, the additional counterweight support frame 20 provides a stable support for the entire system, ensuring a smooth and safe lifting process.
