Abstract
The utility model provides a crawler-type engineering machinery caterpillar track connection piece, comprising a chain pin and a chain relaxing which covers the periphery of the chain pin. The inner and outer chain links are fixed to the two sides of the chain relaxing, and a longer chamfering is provided on the inner and exterior pipe wall on the two ends of the chain relaxing arranged with the inner chain link on the two sides. The chain pin on the out side of the chain relaxing is fixed with the outer chain link, with the arrangement of a wear resistant elastic cushion between the chain relaxing and the outer chain link. The utility model which has the advantages of convenient installation, long service life, and low noise adapts to the crawler belt caterpillar track of the crawler-type engineering machine.
Description
Technical field
The utility model relates to a kind of tracked construction equipment accessory, especially a kind of tracked construction equipment chain rail attaching parts.
Background technology
Tradition tracked construction equipment such as traxcavator, crawler doer etc., its caterpillar chain rail attaching parts, as shown in Figure 2, its chain is logical longer, two ends are directly stretched in the counterbore of outer link, when stressed, can produce the phenomenon of end be full of cracks even fracture, after the chain pin wearing and tearing, this phenomenon is more serious; Simultaneously, the logical two ends of chain hang the wearing and tearing that part can be aggravated outer link counterbore position, and not only can produce very big noise in use, and reduced the service life of chain link.In addition, the very big magnitude of interference is arranged during with chain pin and the assembling of inside and outside chain link in that chain is logical, need very big pressure to be pressed into, press easily partially when making assembling, be difficult for assembling, cause often that chain is logical, chain pin or inside and outside chain link damage when assembling.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to assembly, long service life, reduction to use a kind of tracked construction equipment chain rail attaching parts of noise.
The purpose of this utility model is achieved in that a kind of tracked construction equipment chain rail attaching parts, comprise the logical and chain pin of chain, the logical chain pin periphery that is enclosed within of chain, be fixed with inside and outside chain link on the logical both sides of chain, wherein: the inside and outside tube wall in two ends that chain is logical is equipped with long chamfering, and inner link is fixed on the logical two ends of chain; Outer link is fixed on the chain pin in the logical outside of chain, is provided with wear-resisting cushion at chain between the logical and outer link.
The utility model is owing to adopt said structure, eliminated because of the chain stretching and gone into the chain go side portion crack performance that the chain link counterbore takes place; Tube wall long chamfering in the logical two ends of chain can form an approach cone, has directional tagging, and is convenient for assembly, the damage of the logical and chain link of chain when avoiding assembling; Simultaneously,, not only can reduce the noise in the use greatly, and can prevent that earth from entering between the logical and chain pin of chain, reduce wearing and tearing, increase the service life because of the use of wear-resisting spring washer.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an attaching parts structural representation of the prior art.
Among the figure: chain is logical 1, chain pin 2, inner link 3, outer link 4, wear-resisting cushion 5.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done to describe further, but do not constitute any restriction of the present utility model.
As shown in Figure 1, tracked construction equipment chain rail attaching parts of the present utility model comprises chain logical 1 and chain pin 2, and the inside and outside tube wall in the two ends of chain logical 1 is equipped with long chamfering, forms an approach cone, convenient inner link 3 and the chain pin 2 installed; Inner link 3 is fixed on logical 1 two ends of chain, avoids the two ends of chain logical 1 to stretch in the counterbore of outer link; Outer link 4 is fixed on the chain pin 2 in logical 1 outside of chain, is provided with the wear-resisting cushion 5 by rubber-moulding between chain logical 1 and outer link 4, reduce use noise and reduce chain logical 1 and chain pin 2, chain lead to 1 and outer link 4 between wearing and tearing, increase the service life.
