Description

Walking type excavator landing leg with high stability Technical Field The utility model belongs to the technical field of diggers, and particularly relates to a walking type digger landing leg with high stability. Background Along with the continuous promotion of urban construction, the walking excavator plays an extremely important role in municipal construction and is used for various operations such as road maintenance, garden fruit tree transplanting, grassland piling and the like. Through retrieving, the chinese patent with bulletin number CN208346878U discloses a walking excavator, including bucket, linking arm subassembly and automobile body, the first end of linking arm subassembly is articulated with the bucket, and the second end of linking arm subassembly is articulated with the automobile body, keeps away from on the automobile body linking arm subassembly's one end is provided with the walking wheel. And one end of the vehicle body, which is close to the connecting arm assembly, is provided with a walking auxiliary wheel and a grabbing support leg, so that the vehicle is suitable for complex terrains. However, the support leg at the lower end of the existing excavator needs to be unfolded for supporting during operation, when the excavator supports on the soft ground, the support leg is unstable due to the fact that the contact area between the support leg of the excavator and the ground is relatively small, so that the risk of the excavator during operation is increased, and meanwhile, the fragile soil structure is possibly damaged due to the fact that the support is unstable. Disclosure of utility model The utility model aims to provide a walking type excavator landing leg with high stability so as to solve the problems in the background technology. In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a high walking excavator landing leg of stability, includes the linking arm, the spout has been seted up to one side of linking arm, and sliding connection has the slide in the spout, and the equal sliding connection in both sides of slide has the balladeur train, and one of them all rotates through the bearing frame to be connected with first connecting plate in one side of two balladeur trains, one of them one side fixedly connected with second backup pad of first connecting plate, the both sides of second backup pad all rotate through the pivot to be connected with first backup pad, the both sides of slide all are equipped with the drive assembly who promotes respectively that two first connecting plates remove in the both sides of slide, another the bottom of first connecting plate is equipped with supporting component, the both sides of slide all are equipped with the locking subassembly to the balladeur train. As a further scheme of the utility model, the driving assembly comprises a fixing frame fixedly connected to one side of the fixing frame, and a first oil cylinder for driving the sliding frame to move is fixedly connected to one side of the fixing frame.
