Abstract
A safe and stable creeper tread for a large-scale excavator comprises a bottom plate, wherein two connecting sleeves 1 are arranged in the middle section of one side of the bottom plate; a connecting sleeve 2, a connecting sleeve 3, another connecting sleeve 3 and another connecting sleeve 2 are arranged in the middle section of the other side of the bottom plate in sequence; the safe and stable creeper tread for the large-scale excavator is characterized in that pin positioning blocks are arranged at the end parts of the two connecting sleeves 2 and on the supporting surface of the bottom plate. The pin positioning blocks and the bottom plate adopt a welded form structure. In the utility model, by arranging the pin positioning blocks at the end parts of the connecting sleeves 2, connecting pins are effectively prevented from darting out, the safety and the stability of the creeper tread are improved, and normal and efficient work of the excavator are ensured.
Description
Technical field
The utility model belongs to the accessory of excavating machine and manufactures field, relates in particular to the security and stability caterpillar block that large excavator is used.
Background technology
Caterpillar block is as the vitals of the underpan walking device of excavating machine, for supporting walking and the work of whole excavator equipment, so the safe reliability of caterpillar block operation, for being normally even more important of excavating machine.The mode that connection between two caterpillar blocks is inserted adapter sleeve by connecting pin connects, but in actual practicality, especially goes up large excavator, and connecting pin can be altered place, causes the improper running of caterpillar block, thereby causes the paralysis of excavating machine.
Summary of the invention
The security and stability caterpillar block that provides a kind of large excavator to use is provided the purpose of this utility model, and it is reasonable in design, and the running of caterpillar block is more stable, safety.
The technical solution of the utility model is: the security and stability caterpillar block that a kind of large excavator is used, comprise base plate, one side stage casing of described base plate is provided with two adapter sleeves one, and the opposite side stage casing of base plate is provided with adapter sleeve two, adapter sleeve three, adapter sleeve three, adapter sleeve two successively; It is characterized in that: in the end of described two adapter sleeves two, on the bearing surface of described base plate, be equipped with plunger locating piece.
Two adapter sleeves one and adapter sleeve two, adapter sleeve three, for the connection between two caterpillar blocks, insert by connecting pin.
Described plunger locating piece and base plate are Type of Welding type structure.
Beneficial effect: by the termination at adapter sleeve two, plunger locating piece is set, actv. has prevented scurrying out of connecting pin, has improved the security and stability of caterpillar block, has guaranteed excavating machine work normally and efficiently.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1, base plate, 2, adapter sleeve one, 3, adapter sleeve two, 4, adapter sleeve three, 5, plunger locating piece, 6, bearing surface.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, the security and stability caterpillar block that a kind of large excavator is used, comprise base plate 1, a side stage casing of described base plate 1 is provided with two adapter sleeves 1, and the opposite side stage casing of base plate is provided with adapter sleeve 23, adapter sleeve 34, adapter sleeve 34, adapter sleeve 23 successively; In the end of described two adapter sleeves 23, on the bearing surface 6 of described base plate 1, be equipped with plunger locating piece 5.
Described plunger locating piece and base plate are Type of Welding type structure.
Two adapter sleeves one and adapter sleeve two, adapter sleeve three, for the connection between two caterpillar blocks, insert by connecting pin.
Above-described embodiment is only for the present invention is clearly described, and is not the restriction to embodiment of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And these belong to apparent variation or the change that connotation of the present invention extends out and still belong to protection scope of the present invention.
