Detailed Description

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

The technical scheme of the utility model is further described below with reference to the accompanying drawings. Fig. 1 to 4 show a self-rescue improved structure of a crawler harvester, which comprises a boundary beam 1, a middle cross beam 2 and an L-shaped reinforcing plate 3 which are welded vertically, wherein the L-shaped reinforcing plate 3 is welded at the joint of the boundary beam 1 and the middle cross beam 2, the side plates and the bottom plates of the L-shaped reinforcing plate 3 are respectively welded at the side surfaces and the bottom surfaces of the boundary beam 1, through holes are formed in the middle part of the boundary beam 1, specifically, two concentric first through holes 101 are formed in the two opposite side walls of the boundary beam, meanwhile, a second through hole 301 is concentrically arranged on the L-shaped reinforcing plate 3, the apertures of the first through hole 101 and the second through hole 301 are the same, and thus the rod end of a jack can be inserted into a cavity formed by the first through hole 101 and the second through hole 301. The self-rescue improved structure cancels the interface between welding and the upper part of the chassis, and directly uses the boundary beam as a bearing carrier; through punching on the boundary beam, on the one hand, the L-shaped reinforcing plate is used for reinforcing, and on the other hand, the T-shaped structure is welded with the middle cross beam, so that a T-shaped structural member is formed, and the T-shaped structure has enough strength for supporting the weight of the whole machine, thereby reinforcing the boundary Liang Jin reasonably and effectively. Of course, the space above the chassis is not occupied, and the layout of the components at the adjacent positions of the chassis is not affected. It can be seen that the height of the self-rescue improved structure is flush with the boundary beam, the height is lower, and the chassis can be lifted to the required height more effectively.

In order to increase the connection strength between the side beam and the middle cross beam, a side wall of the side beam 1 and the cross section of the middle cross beam 2 are welded into a whole. The cross section can effectively strengthen the strength of the wall of the first through hole 101 in the boundary beam 1, so that the boundary beam has enough bearing capacity.

The bottom plate of the L-shaped reinforcing plate 3 can be further extended, and the bottom plate is welded to the bottom surface of the side beam 1 and the bottom surface of the middle cross beam 2 while the side plates of the L-shaped reinforcing plate 3 are welded to the side surfaces of the side beam 1, so that the connection strength between the L-shaped reinforcing plate and the side beam and the middle cross beam is further enhanced, and a firm structure is formed between the L-shaped reinforcing plate and the side beam and the middle cross beam.

As shown in fig. 4, on the side plates of the L-shaped reinforcing plate 3, slopes 5 are welded at two ends along the axial direction of the side beam 1, and the side plates are welded on the side surface of the side beam 1, so that the L-shaped reinforcing plate and the side beam can be connected more firmly, and more weight of the fuselage can be borne.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
