Description
Technical field
The utility model relates to a kind of improvement of spider-shaped supporting leg bearing force structure of the detecting device.
Background technology
The supporting leg of tradition aerial platform is generally all provided with supporting leg detecting device, the set-up mode of detecting device, and normally whether direct survey supporting leg is flexible puts in place, and whether props up reality when supporting.For H type supporting leg, its supporting leg bearing force detecting device is divided into horizontal detection and vertically detects, its detection mode is detection supporting leg, and whether flexible is to certain stroke, comparatively simple on physical construction, higher for level land detecting reliability, but cave in or soft terrain in case of ground has, and the fiduciary level of detection just decreases, therefore, traditional supporting leg bearing force detecting device is further improved raising.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of structure simple, can to the ground having depression, or soft terrain carries out the spider-shaped supporting leg bearing force detecting device of reliability detection.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme, the utility model comprises Connection Block, the upper end thereof of Connection Block is provided with oil cylinder, it is characterized in that: the lower end of Connection Block is by first hinge of the first elongated hole with leg ends, the other end of supporting leg is provided with supporting disk, and the piston rod end of oil cylinder is provided with the second bearing pin, and the second bearing pin matches with the second elongated hole of a midleg; Described supporting leg is provided with the upset pressing plate of L shape, bending place and the supporting leg of upset pressing plate are hinged, and the upset vertical section of pressing plate contacts with the end of piston rod, and the traversing section of upset pressing plate is placed on the guide pillar on supporting leg by elongated hole; Retracing spring is provided with between the traversing section of upset pressing plate and supporting leg; Supporting leg is provided with limit switch corresponding to the traversing section of upset pressing plate; Described first bearing pin is provided with the cam rotated with supporting leg, described Connection Block is provided with the locating dowel pin corresponding with cam.
The beneficial effects of the utility model: after the piston rod of the utility model oil cylinder stretches out, first bearing pin and the second bearing pin are moving respectively in the first elongated hole and the second elongated hole, the end of piston rod promotes upset pressing plate and rotates around its hinge, the traversing section compressing retracing spring of upset pressing plate, and leave limit switch, limit switch sends signal, represents that supporting leg props up reality.
