Abstract

The utility model relates to a supporting leg structure for machinery. The supporting leg structure comprises a support fixed on a vehicle, a telescopic oil cylinder and a rectangular supporting leg base. The telescopic oil cylinder is used for expansion of a supporting leg, and the supporting leg base is connected to the bottom of the telescopic oil cylinder. Four hydraulic oil cylinders are in rotatable connection with the lower portion of the supporting leg base, and a rectangular base is connected to the lower portion of each hydraulic oil cylinder. According to the supporting leg structure, the two-section structure is adopted, and effective support can be provided through the supporting leg base; and the four hydraulic oil cylinders are in rotatable connection with the lower portion of the supporting leg base and can turn over to the back of the supporting leg base, and the telescopic supporting leg is far from the ground, so that the probability of collision between the telescopic supporting leg and ground is prevented.

Description

A kind of mechanical leg structure
Technical field
The utility model relates to mechanical equipment technical field, particularly a kind of mechanical leg structure.
Background technology
Hoisting cranes etc. movably are provided with running gear and supporting leg on the vehicle frame of large-scale engineering machinery simultaneously, the oil cylinder of supporting leg is vertically to arrange generally speaking, when oil cylinder extends, piston rod is to expose outside, clashed into than being easy in the rugged environment at the construction field (site), thereby can cause the rod chamber end cap of oil cylinder and the seal break-off between the piston rod, cause the hydraulic oil in the oil cylinder to reveal, have serious potential safety hazard; Simultaneously, be subjected to the restriction of construction machinery and equipment designing requirement, distance between hold-down arm and the ground is fixed, and the vertical height when need guaranteeing that oil cylinder is full reduced is less than the height between hold-down arm and the ground, therefore, the flexible scope of oil cylinder is restricted, oil cylinder easily and ground bump, influence the use of equipment.
Summary of the invention
First purpose of the present utility model aims to provide a kind of mechanical leg structure, its telescopic oil cylinder is made up of two parts, its earth plate can provide effective support, can provide simultaneously to have avoided drive element and ground to bump, 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 mechanical leg structure, comprise the support that is fixed on the vehicle, and be used for the flexible telescopic oil cylinder of supporting leg, be connected the earth plate of telescopic oil cylinder bottom; Described earth plate is rectangle, earth plate bottom four hydraulic rams that have been rotatably connected, and each hydraulic ram bottom is connected with a rectangular base.
As optimization, earth plate bottom four hydraulic rams that have been rotatably connected, turning to the earth plate back side.
As optimization, described support one side is provided with master control switch.
The utility model machinery leg structure adopts two joint designs, and earth plate can provide effective support, base bottom four hydraulic rams that have been rotatably connected, can be turned to the earth plate back side, telescopic outrigger has bigger distance with ground, the probability of having avoided itself and ground to bump.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the utility model machinery 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 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, mechanical leg structure comprises the support 1 that is fixed on the vehicle, is used for the flexible telescopic oil cylinder 2 of supporting leg, is connected the earth plate 3 of telescopic oil cylinder 2 bottoms; Earth plate 3 is rectangle, earth plate 3 bottoms four hydraulic rams 4 that have been rotatably connected, and each hydraulic ram 4 bottom is connected with a rectangular base 5.
Earth plate 3 bottoms four hydraulic rams 4 that have been rotatably connected can be turned to earth plate 3 back sides.
Side at support 1 is provided with for the master control switch 6 of controlling telescopic oil cylinder 2 and hydraulic ram 4.
Mechanical leg structure of the present utility model, adopt two joint designs, earth plate 3 can provide effective support, earth plate 3 bottoms four hydraulic rams 4 that have been rotatably connected, can be turned to earth plate 3 back sides, telescopic outrigger has bigger distance with ground, the probability of avoiding itself and ground to bump.
More than show and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
