Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a crane frame seat ring and a frame. Background Art

[0002] The crane frame is the main load-bearing component during the crane lifting operation. On the basis of bearing other components of the vehicle chassis, it supports and connects the crane vehicle structure through the seat ring. The frame seat ring directly bears the vertical load and bending moment brought by the vehicle lifting operation, so the frame seat ring structure needs to have very high strength and rigidity. In order to prevent the seat ring from being damaged due to excessive load, the seat ring diameter is generally larger than the frame box size, and a diagonal brace plate is welded around the bottom of the cylindrical box. In the prior art, the main load-bearing components of the frame seat ring are diagonal brace plates and upper arc plates of varying numbers. The upper end of the diagonal brace plate is welded to the upper arc plate, and the lower part is welded to the frame belly plate, forming an inverted cone structure.

[0003] This structure of the frame seat ring results in a small space under the seat ring, which has a great impact on the selection of crane tires. In order to make the crane have a smaller ground pressure ratio and carry more parts during transfer or driving, large tires are preferred when configuring the tires of the crane. Therefore, under the premise of ensuring the strength and rigidity of the seat ring structure, how to make the lower part of the seat ring have a larger space to facilitate the installation of tires or other components and better distribute the load is of great significance to improving the applicability and reliability of the crane. Utility Model Content

[0004] In order to solve the problems in the above-mentioned prior art, the utility model provides a crane frame seat ring and frame. The purpose of the utility model is to solve the problem of optimizing the space under the seat ring while ensuring the structural strength and rigidity of the seat ring to provide operating space for selecting and installing tires.

[0005] To achieve the above-mentioned purpose, the first aspect of the utility model provides a crane frame seat ring, which is arranged on the frame and extends to both sides of the frame, including a cylindrical box shape and a plurality of lower support plates, wherein the cylindrical box shape is provided with a plurality of partitions for evenly dividing its internal space, and a rib plate extending along the axial direction of the frame, wherein the upper end of the lower support plate is connected to the rib plate of the cylindrical box shape, and the lower end is connected to the frame.

[0006] Furthermore, the cylindrical box type includes an upper cover plate, a lower bottom plate arranged on both sides of the frame, and an upper arc plate connecting the upper cover plate and the lower bottom plate.

[0007] Furthermore, an auxiliary box-type connecting the frame and the cylindrical box-type is provided at the angle formed by the outer side of the circumference of the cylindrical box-type and the frame.

[0008] Furthermore, the lower support plate is a straight plate or an inwardly concave arc plate.

[0009] Furthermore, the auxiliary box type includes a reinforcing plate and a side sealing plate, and the reinforcing plate and the side sealing plate are combined with the lower bottom plate, the upper arc plate and the frame to form a box-type structure.

[0010] Furthermore, the rib plate is connected to the middle position of the lower base plate.

[0011] A second aspect of the utility model provides a crane frame, comprising the crane frame seat ring as described above.

[0012] Compared with the prior art, the crane frame seat ring and frame of the utility model mainly have the following advantages:

[0013] 1. The crane frame seat ring of the utility model achieves the effect of dispersing loads and reducing stress concentration through the structural form of arc plates and rib plates, thereby improving the strength and rigidity of the seat ring box type. The auxiliary box type makes up for the weak points at the connection position between the frame and the seat ring, enhances the overall reliability of the seat ring, and can meet the performance requirements of the crane when operating in different directions.

[0014] 2. The crane frame seat ring of the utility model optimizes the space below the seat ring box by changing the connection position between the lower support plate and the cylindrical box, which is convenient for the selection of large tires and the arrangement of other components, and is beneficial to the carrying of vehicle transfer components and the improvement of driving performance.

[0021] like Figure 1-2 As shown, a crane frame seat ring plays a role in connecting and supporting the crane upper structure. It is arranged on the frame 4 and extends to both sides of the frame 4 to form an arc-shaped protrusion. It includes a cylindrical box type 1 and a plurality of lower support plates 3. The cylindrical box type 1 is provided with a plurality of partitions 8 that evenly divide its internal space, and a rib plate 9 extending along the axial direction of the frame. The upper end of the lower support plate 3 is connected to the rib plate 9 of the cylindrical box type 1, and the lower end is connected to the frame 4. The lower support plate 3 supports the part of the cylindrical box type 1 protruding from both sides of the frame 4, thereby increasing the structural strength and rigidity of the cylindrical box type 1. At the same time, the lower support plate 3 is connected to the rib plate 9 of the cylindrical box type 1, which reduces the occupation of the lower space of the cylindrical box type 1 and facilitates the installation of crane tires or other components. The applicability and reliability of the crane are improved.

[0022] In some embodiments, the cylindrical box 1 includes an upper cover plate 5, a lower bottom plate 7 provided on both sides of the frame 4, and an upper arc plate 6 connecting the upper cover plate 5 and the lower bottom plate 7. The upper cover plate 5, the upper arc plate 6 and the lower bottom plate 7 are assembled and welded on the frame to form a closed box structure. The cylindrical box 1 is provided with a plurality of partitions 8 that evenly divide its internal space. The partitions 8 extend downward and are connected to the frame 4 to achieve the effect of dispersing loads and reducing stress concentration, further increasing the structural strength and rigidity of the cylindrical box 1.

[0023] In some embodiments, the four corners of the cylindrical box 1 connected to the frame 4 in the circumferential direction are all provided with auxiliary box 2 connecting the cylindrical box 1 and the frame 4. The auxiliary box 2 includes a reinforcing plate 11 and a side sealing plate 10. The reinforcing plate 11, the side sealing plate 10, the lower bottom plate 7, and the upper arc plate 6 are surrounded on the frame 4 to form a box structure. The cylindrical box 1 is auxiliary supported to further enhance the structural strength and rigidity of the cylindrical box 1.

[0024] In some embodiments, Figure 3As shown, the upper end of the lower support plate 3 is welded to the position on the lower base plate 7 aligned with the rib plate 9, and the lower end is welded to the frame 4. The lower support plate 3 is welded to the rib plate 9 of the lower base plate 7, which reduces the space occupied by the lower support plate 3 in the lower part of the cylindrical box type 1. At the same time, the rib plate 9 can increase the rigidity and strength of the cylindrical box type 1, so that the lower base plate 7 can better resist deformation when subjected to load. By welding the lower support plate 3 to the rib plate 9 of the lower base plate 7, the external load can be dispersed to the entire lower base plate 7 through the rib plate 9. The load can be effectively transmitted and dispersed, reducing the risk of stress concentration and improving the stability and durability of the structure.

[0025] In the above embodiment, the lower support plate 3 is a straight plate or an inwardly concave arc plate. When the lower support plate 3 is an inwardly concave arc plate, the lower space of the cylindrical box type 1 can be further optimized to provide a larger operating space for the installation of crane tires.

[0026] The embodiment of the utility model further provides a crane frame, comprising the crane frame seat ring as described above.
