Description
Technical field
The present invention relates to engineering machinery field, relate in particular to a kind of wheel crane and body frame structure for automotive thereof.
Background technology
Wheel crane is road vehicles, is again hoisting operation instrument.Vehicle frame, is first the installation basis of whole wheel crane, for each assemblies and parts of erecting crane, and makes them keep enough arrangement space and correct relative position, and therefore, first the structure of vehicle frame should meet the requirement of car load general layout; Secondly, vehicle frame also bears various quiet, the live load from get on the bus hoisting operation and ground, especially should guarantee enough supporting leg spans during hoisting operation, and unlikely load is excessive and impaired, or topples because supporting leg span is too small.Therefore, in the situation that wheel crane is controlled cost, require vehicle structure compact, vehicle frame should have enough arrangement space to meet the installation of each system; Meanwhile, vehicle frame also should have enough intensity, rigidity and stability.Reasonably body frame structure for automotive could meet light-weight design requirement low-cost, high benefit.
Due to the restriction of car load overall width and lifting performance, from reducing sectional area and the thickness of slab of vehicle frame, be the product that is difficult to design low cost, high benefit merely.In design during large tonnage product, if adopt H type supporting leg, the requirement of limited supporting leg span, it is very large that vehicle frame back segment is often done, and also corresponding increase of vehicle bridge design quantity when weight increases finally causes cost to increase, and is unfavorable for the market competitiveness of product.Therefore, how in limited space, rational deployment, the requirement while making vehicle frame rigidity, strength and stability all meet lift heavy operation is the key of Vehicle Frame Design.
At present, the vehicle frame back segment 1 ' of wheel crane is with the version (as shown in Figure 1) of front oscillating support leg 2 ' and rear telescopic outrigger 3 '.As shown in Figure 2, the upper and lower hinge 4 ' of oscillating support leg 2 ' before vehicle frame back segment 1 ' front portion is provided with and installs, it is upper that this hinge is welded to vehicle frame back segment 1 ', as fixing hinge.By upper and lower two semiaxis 5 ' are installed, vehicle frame back segment 1 ' and front oscillating support leg 2 ' is hinged.Before crane job, the forward and backward oscillation adjustment of oscillating support leg 2 ' before promoting by the oscillating oil cylinder 7 ' on tilt cylinder seat 6 ', to reach suitable supporting leg vertical and horizontal span, meets lifting performance requirement.
As can be seen from the figure, be fixedly connected with upper and lower cover plates and the vehicle frame back segment employing bridging arrangement of the hinge of vehicle frame back segment and front oscillating support leg.From stressed angle analysis, hinge place stress is larger, and easily produces fatigue effect load in operation process.Therefore, easily ftracture in the commissure of this kind of bridging arrangement.In addition, the upper and lower cover plates of hinge adopts monolithic slab not meet light-weight design requirement.
The whole employing of hinge docked form with vehicle frame back segment, and this structure and rear telescopic outrigger dock form class seemingly with vehicle frame, and do not strengthen diagonal ligament.In operation process, outrigger reaction is by this hinge and passed to vehicle frame, hinge place stress is concentrated all the more, and docking section bears very large shearing, so the whole joint of hinge is easy to crack, hinge version is unreasonable, has brought very large potential safety hazard to the reliability of product structure.
