Embodiment Construction

[0015] In order to make the outriggers have good stability in gravel, cobblestone and other terrains, there must be a certain pressure around the outriggers in working condition. Therefore, if figure 1 As shown, the present invention includes a leg sleeve 1, a plurality of first single ears 11 are arranged at intervals at the end of the leg sleeve 1, and a freely retractable inner rod 2 is also provided in the leg sleeve, and the end of the inner rod is provided with a There are several second single ears 21 , and the legs also include the same number of base plates 3 as the first single ears 11 . Such as figure 2 As shown, the base plate is a flat plate, preferably fan-shaped. The base plate 3 is provided with a third single ear 31, the third single ear 31 is hinged with one end of the connecting rod 4, the other end of the connecting rod 4 is hinged with the first single ear 11, and the base plate 3 also has double ears 32, which are connected with the first single ear 11....

Abstract

The invention relates to a part of equipment machinery, and particularly relates to a self-adaptive landing leg of the equipment machinery. The self-adaptive landing leg comprises a landing leg sleeve and base plates, wherein a plurality of first single lugs are arranged at the tail end of the landing leg sleeve at intervals, the landing leg sleeve is further internally provided with an inner retractile rod, and the tail end of the inner rod is provided with a plurality of second single lugs; the base plates equal to the first single lugs and are provided with third single lugs, the third single lugs are hinged with one ends of connecting rods, and the other ends of the connecting rods are hinged with the first single lugs; and each of the base plates is further provided with double lugs connected with the second single lugs. The self-adaptive landing leg provided by the invention can be applied to various soils with macadam, cobblestones and the like, and can enhance the stability of the equipment with the self-adaptive landing leg.

Description

technical field [0001] The invention relates to a mechanical equipment component, in particular to a supporting leg of a mechanical equipment. Background technique [0002] Engineering equipment and machinery such as steel structure bridges and working platforms usually require multiple outriggers to support them in order to improve stability. The outriggers need to provide sufficient support stiffness and have good adaptability to the foundation. The support plates of the current leg structures are mostly in the form of flat plates, that is, they are a rigid plane in a load-bearing state. For example, European patent specifications EP08675666 and EP1243706 disclose a stable leg and a support plate, which can provide stable support on conventional soil. Support force, the soil foundation is subjected to the pressure settlement of the support plate to produce a uniform support reaction force, and there is almost no possibility of lateral sliding of the outriggers.
