Embodiment Construction

[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0031] As a first aspect of the present invention, a positioning support device for a leg of a construction machine is provided. Such as Figure 4 and Figure 5 As shown, the leg positioning and supporting device of the present invention includes: an oil cylinder 30, which is installed on the chassis 10 of the construction machine; a strut 40, one end of the strut 40 is pivotally connected with the piston rod of the oil cylinder 30, and the other end is It is pivotally connected with the outrigger 20 of the engineering machine; the locking member 50 locks the piston rod in at least one position relatively fixed to the chassis 10 . Preferably, the oil cylinder 30 is arranged along the traveling direction of the construction machine. In a preferred...

Abstract

Engineering machinery and a landing leg positioning and supporting device thereof. The landing leg positioning and supporting device comprises: an oil cylinder (30), the oil cylinder (30) being mounted on a chassis (10) of the engineering machinery; a supporting rod (40), one end of the supporting rod (40) being pivotably connected to a piston rod of the oil cylinder (30), and the other end being pivotably connected to a landing leg (20) of the engineering machinery; and a locking piece (50), the locking piece (50) locking the piston rod to at least one position which is relatively fixed with the chassis (10). The supporting rod (40) is driven by the landing leg (20) to swing, position, and support the landing leg (20), so that the oil cylinder (30) only has a function of rotation, thereby reducing the size of the oil cylinder and reducing the cost. In addition, the landing leg positioning and supporting device avoids the over-positioning problem of the supporting rod (40) and the oil cylinder (30), so that the length of the supporting rod (40) does not need to be adjusted, having the advantages of convenient operation and high work efficiency.

Description

technical field [0001] The present invention relates to the field of engineering machinery, and more specifically, to an engineering machinery and a positioning support device for its outriggers. Background technique [0002] Many engineering vehicles in the prior art have outriggers, such as wheeled cranes with large tonnage and super large tonnage. Taking wheeled cranes as an example, it mainly uses large-span radial outriggers. Due to the large load, the cross-section design of the outrigger structure is enlarged. Therefore, the outriggers cannot be designed on the frame like small and medium tonnage wheeled cranes. Therefore, The radial outrigger structure is widely used. This outrigger structure first needs to realize the swing out and retraction of the outrigger. [0003] Figure 1-Figure 3 The structural schematic diagrams of the positioning and supporting devices of three kinds of outriggers in the prior art are respectively shown. [0004] exist figure 1 In the...
