Abstract
The utility model relates to a front-extension rear-oscillation support leg of a concrete pump car, which belongs to a support leg of a concrete pump car. The support leg is provided with a rotary base, wherein the front part of the rotary base is connected with an extension type support leg and an extension oil cylinder connected between the rotary base and the extension type support leg is positioned in the rotary base and the extension type support leg. The back part of the rotary base is connected with an oscillation type support leg through a pin shaft, and an oscillation oil cylinder is connected between the rotary base and the oscillation type support leg, wherein the oscillation oil cylinder is positioned on the rotary base and the bottom surface of the oscillation type support leg and the end parts of the extension type support leg and the oscillation type support leg are both connected with a vertical oil cylinder which is downward vertically. The support leg with artful design gives full play to the advantages of the extension type support leg and the oscillation type support leg, carries out construction in a narrow construction site without the limitation of working space, simultaneously alleviates the weight of car unloading and enlarges the working range of concrete pump cars.
Description
Technical field
The utility model relates to a kind of supporting leg of concrete pump truck, oscillating-type supporting leg after particularly a kind of concrete pump truck front stretching.
Background technology
At present, the domestic concrete pump truck supporting leg connection mode of getting off generally is divided into two kinds of connection modes: a kind of front and back supporting leg be the oscillating-type supporting leg, another kind of before and after supporting leg be the concertina type supporting leg, two kinds of supporting leg modes respectively have its excellent, shortcoming, the oscillating-type supporting leg can carry out work by rapid deployment, but its scantling of structure characteristic is subjected to the restriction in operation place, can not be at narrow site construction; The concertina type supporting leg is subjected to the influence of its oad, must make very big that the weight of getting off does.
Summary of the invention
The purpose of this utility model be to provide a kind of can be after the little concrete pump truck front stretching of narrow site construction, the weight of getting off the oscillating-type supporting leg.
The purpose of this utility model is achieved in that this supporting leg changes base once, is connected with the concertina type supporting leg in the place ahead of rotary table, is connected with telescopic oil cylinder between rotary table and concertina type supporting leg, and telescopic oil cylinder is positioned at rotary table and Retractive leg; Rear at rotary table is connected with the oscillating-type supporting leg by bearing pin, is connected with oscillating oil cylinder between rotary table and oscillating-type supporting leg, and oscillating oil cylinder is positioned on the bottom surface of rotary table and oscillating-type supporting leg; All be connected with vertical oil cylinder vertically downward in the end of concertina type supporting leg and oscillating-type supporting leg.
Beneficial effect: owing to adopt such scheme, telescopic oil cylinder one end is in rotary table, the other end is contained in the Retractive leg, telescopic outrigger also is contained in the rotary table simultaneously, the swing of the telescopic band movable pendulum supporting leg of flexible, the oscillating oil cylinder of the flexible drive left and right sides Retractive leg of telescopic oil cylinder, to meet the requirements of the supporting leg span, vertical then oil cylinder stretches out, car load can be worked, on a car load, made full use of the advantage of two kinds of supporting legs, can alleviate the weight of getting off again in narrow site construction, while, reach the purpose of this utility model.This supporting leg is skillfully constructed, and gives full play to the advantage of concertina type supporting leg and oscillating-type supporting leg, can not limited by working space, has alleviated the weight of getting off again in narrow site construction, while, has enlarged the range of use of concrete pump truck.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
Embodiment 1: 1, left telescopic outrigger; 2, right telescopic outrigger; 3, rotary table; 4, bearing pin; 5 right oscillating support legs; 6 vertical oil cylinders; 7 oscillating oil cylinders; 8, left oscillating support leg.
This supporting leg changes base 3 once, be connected with the concertina type supporting leg in the place ahead of rotary table 3, the concertina type supporting leg is divided into left telescopic outrigger 1 and right telescopic outrigger 2, be connected with telescopic oil cylinder between rotary table and concertina type supporting leg, telescopic oil cylinder is positioned at rotary table 3, left telescopic outrigger 1 and right telescopic outrigger 2; Rear at rotary table 3 is connected with the oscillating-type supporting leg by bearing pin 4, the oscillating-type supporting leg is divided into left oscillating support leg 8 and right oscillating support leg 5, be connected with oscillating oil cylinder 7 between rotary table 3 and oscillating-type supporting leg, oscillating oil cylinder 7 is positioned on the bottom surface of rotary table 3 and oscillating-type supporting leg; All be connected with vertical oil cylinder 6 vertically downward in the end of concertina type supporting leg and oscillating-type supporting leg.
The operation hydraulic valve makes telescopic oil cylinder flexible, and it is flexible that telescopic oil cylinder drives the concertina type supporting leg, and the swing of the moving supporting leg of telescopic band movable pendulum by oscillating oil cylinder meets the requirements of the supporting leg span.
The utility model is fully to study on the basis of concrete pump truck mode of operation, domestic first unique connection mode of " oscillating-type leg structure after the concrete pump truck front stretching " has been proposed, stretching of flexible drive front stretching leg by the front stretching oil cylinder reaches the swing of the drive back oscillating support leg that contracts of oscillating oil cylinder thereafter, car load played the effect of support.Unique connection mode of innovative design is not limited by working space, is more convenient at narrow site construction.
