Abstract
The utility model discloses a mechanical supporting leg device. The mechanical supporting leg device comprises a supporting leg, a supporting foot, a truck frame and a telescopic cylinder. The telescopic cylinder is arranged longitudinally, a base of the telescopic cylinder is hinged to the truck frame, a slide block is hinged to the lower portion of the telescopic cylinder, a slide groove is formed in the middle of the supporting leg, and the slide block can be fixed on the slide groove in a sliding mode. According to the mechanical supporting leg device, after the supporting leg is withdrawn, the distance between the mechanical supporting leg device and the ground is large, and therefore the probability of collision of the mechanical supporting leg device and the ground is avoided.
Description
Technical field
The utility model relates to mechanical engineering field, particularly a kind of mechanical support leg device.
Background technology
Concrete pump trucks etc. movably are provided with running gear and supporting leg on the vehicle frame of large-scale engineering machinery simultaneously, and supporting leg is provided with four usually, and four supporting legs are distributed in four jiaos of construction machinery and equipment, and in the support of the paired construction machinery and equipment of quadrangle.During normal operation, supporting leg is in deployed condition usually, and the oil cylinder of leg ends stretches out and is supported in ground, the stationarity during with the work of maintenance car load; Yet, 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.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, mechanical support leg device easy to use.
To achieve these goals, the technical solution of the utility model is as follows: a kind of mechanical support leg device comprises supporting leg, leg, vehicle frame, telescopic oil cylinder; Described telescopic oil cylinder vertically arranges, and telescopic oil cylinder base and vehicle frame are hinged, telescopic oil cylinder lower hinge one slide block, and a midleg is provided with chute, and slide block slidably is fixed on the chute.
Further, an end of described supporting leg connects leg, and an other end of supporting leg is hinged on the vehicle frame.
Further, described supporting leg and vehicle frame hinged place height are lower than telescopic oil cylinder base and vehicle frame hinged place height.
Adopt the mechanical support leg device of technique scheme, because described telescopic oil cylinder vertically arranges, telescopic oil cylinder base and vehicle frame are hinged, telescopic oil cylinder lower hinge one slide block, prop up midleg and be provided with chute, slide block slidably is fixed on the chute, and an end of described supporting leg connects leg, an other end of supporting leg is hinged on the vehicle frame, and described supporting leg and vehicle frame hinged place height are lower than telescopic oil cylinder base and vehicle frame hinged place height; Therefore supporting leg reclaims the back 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 structural representation of the utility model random tool support leg device.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
As shown in Figure 1, a kind of mechanical support leg device comprises supporting leg 1, leg 2, vehicle frame 3, telescopic oil cylinder 4; Described telescopic oil cylinder 4 vertically arranges, and telescopic oil cylinder 4 bases and vehicle frame 3 are hinged, telescopic oil cylinder 4 lower hinge one slide block 5, supporting leg 1 middle part is provided with chute 6, slide block 5 slidably is fixed on the chute 6, and an end of supporting leg 1 connects leg 2, and an other end of supporting leg 1 is hinged on the vehicle frame 3.Supporting leg 1 is lower than telescopic oil cylinder 4 bases and vehicle frame 3 hinged place height with vehicle frame 3 hinged place height.
Mechanical support leg device of the present utility model, in the time of need stretching out supporting leg 1, telescopic oil cylinder 4 promotes the hinged slide block 5 in its underpart and moves down.Slide in the chute 6 of slide block 5 on supporting leg 1, drive supporting leg 1 and move down, thereby be supported in ground; When needing withdrawal supporting leg 1, telescopic oil cylinder 4 spurs on the hinged slide block 5 in its underparts and moves.Slide in the chute 6 of slide block 5 on supporting leg 1, drive supporting leg 1 and move up, supporting leg 1 is regained; The support leg device of the utility model construction machinery and equipment, its supporting leg reclaims the back has bigger distance with ground, the probability of having avoided 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.
