Description

Technical Field

[0001] The utility model relates to the technical field of excavator accessories, in particular to an excavator frame connecting rod. Background Art

[0002] During the manufacturing process of the excavator, the frame connecting column is needed, through which other parts of the excavator can be connected to the frame;

[0003] Patent application number CN202022309444.7 discloses an excavator frame connecting rod. The patent first moves the special-shaped flange 2 and two connecting rods 1 to a suitable position and arranges them, aligns the positions of the nut mounting holes, and uses the locking nut 3 to insert the nut mounting hole so that the two connecting rods 1 and the special-shaped flange 2 form a stable fixing mechanism. The sealing ring 4 jacket is checked to complete the preliminary installation. By setting the special-shaped flange 2, the processing procedure can be simplified, the welding operation is omitted, and the connection is more solid. The occurrence of breakage and loosening is reduced during use, which greatly reduces the production cost.

[0004] The excavator frame connecting rod in the prior art cannot be easily processed during actual use. The main reason is that threaded holes need to be opened on the connecting rod, and the bolts are connected on opposite sides of the two connecting rods, which also increases the difficulty of bolt connection operation. In addition, the feasibility of using springs for buffering and weight reduction in the prior art is poor. The existing connecting column is usually made of cast iron. Once the connecting column is deformed, it will break, and the supporting role of the spring can be ignored in practice. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an excavator frame connecting rod to solve the problem that the connection of the excavator frame connecting rod in the prior art described in the background technology is relatively complicated and the strength is relatively low.

[0006] To achieve the above purpose, the utility model provides the following technical solutions: an excavator frame connecting rod, comprising

[0007] The two connecting rod bodies each have a plurality of positioning holes distributed along the connecting rod body and penetrating the connecting rod body;

[0008] A plurality of connecting columns respectively penetrate through the positioning holes at corresponding positions on the two connecting rod bodies;

[0009] A connecting plate, fixedly connected to one end of the connecting rod body;

[0010] Wherein, the outer circumferential wall of one end of the connecting column away from the connecting plate is provided with an external thread;

[0011] a partition plate, located between the two connecting rod bodies;

[0012] A plurality of through holes are respectively arranged on the partition plate at positions corresponding to the connection columns, and the connection columns penetrate the through holes at corresponding positions;

[0013] A plurality of nuts are respectively connected with external threads on a plurality of connecting columns through threads so as to clamp the partition plate between the two connecting rod bodies.

[0014] Preferably, the number of the positioning holes on each connecting rod body is at least two.

[0015] Preferably, the side walls on both sides of the connecting rod body are provided with outer protrusions at positions corresponding to the positioning holes.

[0016] Preferably: one end of the connecting column passing through the nut has a through hole, and the through hole has an open latch passing through the through hole.

[0017] Preferably, the surfaces where the two connecting rod bodies intersect the partition plates are both rough surfaces.

[0018] The beneficial effects of adopting the above technical solution are:

[0019] The nut provided in the present application can be connected with the external thread, so that the connecting plate and the nut can clamp the two connecting rod bodies, and the two connecting rod bodies can clamp the partition plate, thereby fixing the two connecting rod bodies together, and the positioning hole on the connecting rod body in the present application is integrally formed with the connecting rod body during casting, avoiding manual drilling;

[0020] In the present application, the two ends of the partition plate are non-extended so that the partition plate can increase the strength of the connecting rod body and avoid deformation of the connecting rod body. Compared with the existing technology, the strength is stronger. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-7 In the first embodiment, an excavator frame connecting rod includes

[0031] The two connecting rod bodies 10 each have a plurality of positioning holes 31 distributed along the connecting rod body 10 and penetrating the connecting rod body 10;

[0032] A plurality of connecting posts 30 respectively penetrate through the positioning holes 31 at corresponding positions on the two connecting rod bodies 10;

[0033] A connecting plate 33, fixedly connected to one end of the connecting rod body 10;

[0034] The connecting column 30 has an external thread 32 on its outer circumferential wall at one end away from the connecting plate 33;

[0035] A partition plate 50 is located between the two connecting rod bodies 10;

[0036] A plurality of through holes 51 are respectively disposed on the partition plate 50 at positions corresponding to the connection posts 30, and the connection posts 30 pass through the through holes 51 at corresponding positions;

[0037] A plurality of nuts 40 are respectively connected to the external threads 32 on a plurality of connecting posts 30 through threads, so as to clamp the partition plate 50 between the two connecting rod bodies 10 .

[0038] This embodiment is implemented as follows:

[0039] When the present application is in use, the partition plate 50 is first placed between the two connecting rod bodies 10 so that the through hole 51 is aligned with the positioning hole 31, the connecting column 30 on the connecting plate 33 is passed through the positioning hole 31 on the connecting rod body 10 and the through hole 51 and the gasket ring 41 on the partition plate 50, and then the nut 40 is connected to the external thread 32 on the connecting column 30. At this time, the nut 40 and the connecting plate 33 can clamp the two connecting rod bodies 10, and the partition plate 50 can separate the two connecting rod bodies 10. Selecting partition plates 50 of different lengths and thicknesses can be suitable for frame connecting rods with different requirements. Therefore, the use of the present application is more flexible. At the same time, the partition plate 50 can prevent the two connecting rod bodies 10 from deforming, which is more effective than the spring in the prior art.

[0040] The advantage of the present application over the prior art is that it is more flexible and stable to use.

[0041] See also Figure 1 , 2 3. The number of the positioning holes 31 on each connecting rod body 10 is at least two;

[0042] When the vertical length of the positioning holes 31 is greater than two, the connection between the two connecting rod bodies 10 is more stable.

[0043] See also Figure 7 , the side walls of the connecting rod body 10 have outer protrusions 11 at positions corresponding to the positioning holes 31;

[0044] The outer protrusion 11 can strengthen the position of the connecting rod body 10 corresponding to the positioning hole 31 to avoid breakage there.

[0045] See also Figure 1 , 2 3. One end of the connecting column 30 passing through the nut 40 has a through hole 61, and the through hole 61 has a split latch 60 passing through the through hole 61;

[0046] The split pin 60 passes through the through hole 61 on the connecting column 30 so that the nut 40 is not easy to fall off.

[0047] The surfaces where the two connecting rod bodies 10 intersect the partition plate 50 are both rough surfaces;

[0048] By providing the intersecting surface between the connecting rod body 10 and the partition plate 50 as a rough surface, the connecting rod body 10 and the partition plate 50 can be prevented from moving relative to each other.

[0049] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
