Abstract
The utility model discloses a landing leg structure of a small crane. The landing leg structure comprises a bracket fixedly arranged on a vehicle, a telescopic cylinder for stretching a landing leg and a landing leg base connected with the bottom of the telescopic cylinder, wherein threads are arranged on the outer surface of the telescopic cylinder and the telescopic cylinder is in threaded connection with the bracket through the threads. A convex part is connected with the top of the telescopic cylinder. According to the landing leg structure of the small crane, the telescopic cylinder and the bracket are connected through the threads, when the vehicle moves, the telescopic cylinder can be rotatably moved to the upper part of the bracket through the threads, so that the distance between the telescopic landing leg and ground is increased, and the probability of collision between the telescopic landing leg and the ground is avoided.
Description
Technical field
The utility model relates to mechanical equipment technical field, particularly a kind of small crane leg structure.
Background technology
Hoisting cranes etc. are movably provided with running gear and supporting leg on the vehicle frame of large-scale engineering machinery simultaneously, generally the oil cylinder of supporting leg is vertically to arrange, when oil cylinder extends, piston rod is outside exposed, compared with being easy in rugged environment, clashed at the construction field (site), thereby can cause the rod chamber end cap of oil cylinder and the seal break-off between piston rod, cause the hydraulic oil in oil cylinder to reveal, have serious potential safety hazard; Simultaneously, be subject to the restriction of construction machinery and equipment designing requirement, distance between hold-down arm and ground is fixed, and be vertically highly less than the height between hold-down arm and ground need to guarantee that oil cylinder is full reduced time, therefore, the flexible scope of oil cylinder is restricted, oil cylinder easily and ground bump, affect the use of equipment.
Summary of the invention
First object of the present utility model aims to provide a kind of small crane leg structure, can provide to keep away oil cylinder and ground bumps, and has improved the in-use performance of construction machinery and equipment.
For achieving the above object, the technical solution of the utility model is: a kind of small crane leg structure, comprise the support being fixed on vehicle, and for the telescopic oil cylinder of landing leg stretching, be connected to the earth plate of telescopic oil cylinder bottom; Described telescopic oil cylinder outside face is provided with screw thread, by screw thread, is threaded with described support.
As optimization, can be connected with at telescopic oil cylinder top a jut.
The utility model small crane leg structure, its telescopic oil cylinder and support are together by a threaded connection, can be by during vehicle mobile, and telescopic oil cylinder moves to support top by screw thread rotation, thereby increased the distance of telescopic outrigger with ground, the probability of having avoided itself and ground to bump.
Accompanying drawing explanation
Fig. 1 is the utility model small crane leg structure structural representation.
The specific embodiment
The utility model is described in further detail for embodiment plan given below; but can not be interpreted as it is the restriction to the utility model protection domain; those skilled in the art to nonessential improvement and adjustment more of the present utility model, still belong to protection domain of the present utility model according to the utility model content.
As shown in Figure 1, small crane leg structure, comprises the support 1 being fixed on vehicle, for the telescopic oil cylinder 2 of landing leg stretching, is connected to the earth plate 3 of telescopic oil cylinder 2 bottoms; Telescopic oil cylinder 2 outside faces are provided with screw thread 4, by screw thread 4, are threaded with described support 1.Telescopic oil cylinder 2 tops are connected with a jut 5.
