Abstract
The utility model discloses a wetland excavator chassis traveling chain structure which comprises a pin shaft, outer clamping plates, inner clamping plates, a roller and a middle sleeve, wherein the middle sleeve wraps the pin shaft, the inner clamping plates are clamped at two ends of the middle sleeve, the roller wraps the middle sleeve which is an eccentric sleeve, and the outer clamping plates are positioned at two ends of the pin shaft and clamp the inner clamping plates. The middle sleeve of the wetland excavator chassis traveling chain structure is designed into an eccentric structure, so that service time of a track shoe upper chain is prolonged, and chain maintenance period of a wetland excavator is prolonged.
Description
Technical field
The utility model relates to a kind of walking chain of wetland excavator, in particular a kind of wetland excavator chassis walking chain structure.
Background technology
The wetland excavator high efficiency, but working is abominable, when therefore walking the caterpillar block chain is had relatively high expectations, the middle cover lower surface serious wear of chain, and upper surface does not have any wearing and tearing substantially.The chain of existing wetland excavator is to overlap in the heart together, often be worn through with overlapping lower surface in the heart, but upper surface does not have wearing and tearing substantially, causes the top surface waste, and has greatly reduced the service life of overlapping in the chain.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and walking chain structure in a kind of wetland excavator chassis is provided, and the middle cover of chain is improved.
The utility model is achieved through the following technical solutions, and the utility model comprises bearing pin, external splint, inner splint, roller and middle cover; Described middle cover is coated on the bearing pin, and inner splint is held on the two ends of middle cover, puts during roller is coated on, and external splint is positioned at two ends and the clamping inner splint of bearing pin, and described middle cover is eccentric bushing.
On the center that is centered close to roller of described bearing pin, in when work, can guarantee that the abrasion loss of upper and lower surface of chain is suitable.
The utility model has the following advantages compared to existing technology: the utility model becomes eccentric structure with the middle Analysis of Nested Design of wetland excavator chassis walking chain, has increased the period of service of chain on the caterpillar block, prolongs the chain maintenance period of wetland excavator.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to structural representation.
The specific embodiment
The below elaborates to embodiment of the present utility model; present embodiment is implemented under take technical solutions of the utility model as prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, present embodiment comprises bearing pin 1, external splint 2, inner splint 3, roller 4 and middle cover 5; Described middle cover 5 is coated on the bearing pin 1, and inner splint 3 is held on the two ends of middle cover 5, and roller 4 is coated on the middle cover 5, and external splint 2 is positioned at two ends and the clamping inner splint 3 of bearing pin 1, and described middle cover 5 is eccentric bushing.
In the present embodiment, on the center that is centered close to roller 4 of bearing pin 1, realize its center not being overlapped eccentric structure, when work, can guarantee that the abrasion loss of upper and lower surface of chain is suitable.
