Description

Frame-type body frame structure for automotive and concrete pump truck
Technical field
The utility model relates to engineering machinery field, relates in particular to a kind of frame-type body frame structure for automotive and concrete pump truck.
Background technology
Concrete pump truck is a kind of with the construction machinery and equipment of concrete conveyance to assigned address.The body frame structure for automotive that concrete pump truck is got off (referring to Fig. 1) generally is comprised of three parts: rotary table a1, supporting leg a2 and subframe a3.When pump truck was worked, supporting leg a2 launched to provide enough areal of supports, guaranteed pump truck safety and stability at work; Chassis with subframe a3 under rotary table a1 is connected, and upward is connected with boom, plays the effect of forming a connecting link.
At present, the front leg strut of concrete pump vehicle supporting leg structure mainly is divided into swinging structure, X stretching structure and H type structure, and rear support leg is divided into swinging structure and H type structure.Different according to front and back leg structure form, concrete pump truck rotary table structure mainly is divided into two kinds at present: " putting after front X " type rotary table shown in Figure 2, and namely front leg strut X is flexible, and rear support leg swings; Double pendulum leg type rotary table shown in Figure 3, namely the front and back supporting leg is and leads leg.
Along with the development in market and the client variation to the concrete pump truck demand, the pump truck type spectrum is enriched constantly perfect.Yet, count in pump truck (below 30 meters) research and development, for giving full play to the load-carrying capacity on chassis at millet, often select bridge number less chassis, to reach the purpose of cost efficiency, due to the restriction of suspension chassis load-carrying capacity, the pump truck design should be taked the light-weight design means as far as possible.The body frame structure for automotive of getting off of the H type supporting leg shown in Fig. 4 A, 4B for example, such vehicle frame generally is applied to millet and counts pump truck, and rear support leg case and rotary table split, and generally is placed on the subframe afterbody, rear support leg is H type supporting leg, and front leg strut can arrange X supporting leg or H type supporting leg as the case may be.
No matter bassinet structure under this quasi-tradition is that " putting after front X " type or double pendulum leg type all belong to box-structure, and rotary table integral body is large box-structure, and the part splits some little box-structures, first weld with subframe during connection, then integral body is connected with the chassis.This kind structural stability is better, can place fuel tank in rotary table inside, but overall weight is heavier, box-structure is very inconvenient when concrete pump truck is keeped in repair, and the rotary table structure is comparatively complicated in addition, and processing technology is loaded down with trivial details, especially the X-type earth plate is higher to requirement on machining accuracy, and box-structure forms the enclosure space load-bearing by some steel plates, the loss of weight limited space, and the millet that is not suitable for stressed less is counted pump truck.Therefore millet is counted the pump truck body frame structure for automotive version that should break traditions in design, seeks more reasonable, effective method.
