Description
Technical Field
The utility model belongs to the technical field of track shoes, and particularly relates to a flat-bottom track shoe of an excavator.
Background
The creeper tread is one of chassis parts of engineering machinery, is a vulnerable part of the used engineering machinery, and is commonly used in engineering machinery such as excavators, bulldozers, crawler cranes, pavers and the like. The common creeper tread is divided into three types of single-rib, three-rib and flat bottom according to the grounding shape, and a triangular creeper tread is adopted in individual creeper treads, wherein the single-rib creeper tread is mainly used for a bulldozer and a tractor, because the creeper tread is required to have higher traction capacity when the machinery works, but the single-rib creeper tread is used rarely on an excavator, and the creeper tread is only used when a drilling rig is arranged on the excavator or the excavator requires higher horizontal thrust, so that the higher creeper tread (namely the pedestrade) can extrude soil (or a ground skin) between the creeper treads, and the maneuverability of the excavator is influenced.
After ten years of infrastructure construction in China, at present, highways, national roads, rural roads and urban streets are finished, the roads are asphalt pavements or cement pavements, the existing tracks are not suitable for the current working requirements in the process of needing crawler-type engineering machinery for reconstruction or maintenance, and the like, the lower parts of track shoes of forged profiles of the engineering machinery such as a crawler-type excavator, a bulldozer, a crane and the like are in tooth shapes, and in actual use, the track shoes can move back and forth in the using process to cause irreversible damage to the surfaces of the roads such as a painted road and a cement road.
Therefore, the existing track shoe cannot meet the requirements in practical use, so that an improved technology is urgently needed in the market to solve the problems.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a flat-bottom track shoe of an excavator, which has two working states of a flat bottom and a toothed state by arranging the flat-bottom plate, is adjusted to be in the flat bottom state when the excavator needs to walk on the surfaces of roads such as painted roads, cement roads and the like, and is adjusted to be in the toothed state when the excavator works on the ground, so that the problem that the surfaces of the roads such as painted roads, cement roads and the like are irreversibly damaged because the lower surface of the track shoe of a forged profile of engineering machinery such as the existing crawler excavator, bulldozer, crane and the like is toothed and can move back and forth in the using process in actual use.
In order to solve the technical problems, the utility model is realized by the following technical scheme:
the utility model relates to a flat-bottom track shoe of an excavator, which comprises a track shoe main body and a flat bottom plate, wherein the bottom of the track shoe main body is provided with track teeth, two ends of each track tooth are respectively provided with a first side plate, and a slotted hole is formed in each first side plate;
be provided with on the flat bed with athey tooth matched with bar through-hole, the both ends of flat bed all are provided with the second curb plate, be provided with the bolt hole on the second curb plate, lock through the bolt between second curb plate and the first curb plate.
Further, the middle part of the track shoe main body is provided with four mounting holes, and the mounting holes are used for mounting the flat-bottom track shoe on an excavator.
Further, the first side plate and the track shoe main body are integrally formed.
Further, the second side plate and the flat bottom plate are integrally formed.
Further, the bottom surface of the flat bottom plate is flush with the bottom surface of the track tooth in a flat bottom state, and the bottom surface of the flat bottom plate is higher than the bottom surface of the track tooth in a toothed state.
The utility model has the following beneficial effects:
the utility model has the advantages that the flat bottom plate is arranged, so that the track shoe of the excavator has two working states of flat bottom and tooth shape, when the excavator needs to walk on the surfaces of painted roads, cement roads and other roads, the position of the flat bottom plate is adjusted to enable the bottom surface of the flat bottom plate to be flush with the bottom surfaces of the crawler teeth, thereby the bottom surface of the whole creeper tread is a whole plane, the tooth-shaped underside of the creeper tread of the forged section bar of the traditional engineering machinery such as a crawler excavator, a bulldozer, a crane and the like is avoided, and in the actual use, because the creeper tread can move back and forth in the use process, the problem of irreversible damage to the surfaces of painted roads, cement roads and other roads is solved by adjusting the position of the flat bottom plate when the excavator is in a working ground so that the bottom surface of the flat bottom plate is higher than the bottom surface of the crawler teeth, therefore, the bottom surface of the whole track shoe forms a tooth shape, and the excavator can conveniently grab the ground to walk.
