Abstract
The invention belongs to the field of large heavy machinery, and particularly relates to a cast and welded large crawler plate. The cast and welded large crawler plate comprises a crawler plate body and a crawler joint, wherein protruding parts are arranged on the upper surface of the crawler plate body; the crawler joint is welded to the protruding parts; due to frequent rotation of the crawler joint, the crawler joint is made of a high-strength wear-resistant material; after the outer shape of the cast crawler joint is machined and two groups of holes are bored, the crawler joint and the crawler plate body are welded together, so that the strength of the crawler plate can be ensured and the cost of a raw material can be reduced; the cast and welded large crawler plate solves the problem that through simplex casting, requirements on properties of the large crawler plate cannot be met.
Description
Technical field
The invention belongs to large-scale heavy duty mechanical field, particularly relate to a kind of casting and weld the Large Caterpillar combined.
Background technology
Crawler belt forms by caterpillar block is end to end, often works in harsh environment, and because its carrying is large, fatigue wear is serious, needs higher resistance to abrasion so general.For middle-size and small-size crawler belt, the casting of general employing high-abrasive material forms; But for the crawler belt of large-scale heavy duty machinery, operating mode is poorer, and carrying is larger, and fatigue wear is even more serious, in order to reduce specific pressure over the ground, caterpillar block design outline size is greatly to about 3500*800, if all cast with high-abrasive material, not only material cost exceeds several times, and due to size too large, casting manufacturability is poor, and castability cannot ensure at all, out of reach requirement of strength.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of cost is low, high strength, resistance to abrasion are good casting and weld the Large Caterpillar combined, it is characterized in that: comprise track plate and track section, the upper surface of described track plate is provided with salient, described track section and salient welding.
Described salient is provided with 2, and described track section is arranged on the centre of 2 salients.
Described salient is provided with cavity A, and described track section inside is provided with cavity B.
Beneficial effect of the present invention is: because track section frequently rotates, track section adopts High Strength Wear-Resistance Material to make, after good for track section Mechanical processing of casting profile and boring two groups of holes, be welded as a whole with track plate, not only ensure that the intensity of crawler belt but also the cost of raw material can be reduced, actv. solves the performance requriements that simple casting cannot reach Large Caterpillar, salient is arranged to 2, and track section is arranged on the centre of 2 salients, the welding of track section can be reinforced, make crawler belt resistance to abrasion stronger, simultaneously by salient, track section inside is provided with cavity, can conservation, reduce costs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of track plate of the present invention;
Fig. 3 is the structural representation of track section of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, the present invention is described further:
In figure: 1-track plate, 2-track section, 3-salient, 4-cavity A, 5-cavity B.
Embodiment:
The present embodiment comprises track plate 1 and track section 2, the upper surface of track plate 2 is provided with salient 3, track section 2 and salient 3 weld, and salient 3 is provided with 2, and track section 2 is arranged on the centre of 2 salients 3, the welding of track section 2 can be reinforced like this, make crawler belt resistance to abrasion stronger, salient 3 is provided with cavity A4, and track section 2 inside is provided with cavity B5, like this can conservation, reduce costs.
Utilize technical solutions according to the invention, or those skilled in the art being under the inspiration of technical solution of the present invention, designing similar technical scheme, and reach above-mentioned technique effect, is all fall into protection scope of the present invention.
