Abstract
The utility model relates to a loading power arm frame type concrete delivery pump truck, comprising a chassis, a power system, a folding type cantilever crane system, a pumping system, a hydraulic system, an electrical system and four swing flexible landing legs. The loading power arm frame type concrete delivery pump truck is characterized in that the power system is provided with a chassis engine and a loading engine; the chassis engine provides travelling power for a delivery pump truck; and the loading engine is arranged on a frame above the chassis of rear wheels of the pump truck and provides hydraulic power for the pumping system and the folding type cantilever crane system. Pumping power of the loading power arm frame type concrete delivery pump truck provided by the utility model is provided by the loading engine, the chassis engine can be shut down during operation, oil consumption is greatly reduced.
Description
Technical field
The utility model relates to a kind of boom type pump truck, particularly discloses a kind of dress power arm posture concrete pump truck of going up, and belongs to technical field of engineering machinery, is applied to the constructional engineering machinery concrete pumping machinery.
Background technology
At present, in the concrete construction of national key construction project, all adopted the concrete pump truck pumping technology, its scope of application has spreaded all in the engineerings such as water conservancy, water power, subway, bridge, large foundation, highrise building and civilian construction.Become the first-selected type of pumping concrete construction machinery in recent years.
Concrete mixer can once be accomplished the conveying and the cloth operation of on-site concrete simultaneously, has that pump-conveying property is good, characteristics such as the cloth scope is big, walking voluntarily, maneuverability and convenient transfer.Especially on the basis, low layer construction and need frequently when shifting the building site, use concrete mixer more can show its superiority.Adopt its easy construction, in the jib scope of activities, can change the concreting position arbitrarily, do not need interim at the scene tubing, can save the shop and help the time, improve work efficiency.Be specially adapted to that the concreting demand is big, the one-time-concreting and the high engineering of quality requirement of ultra-large volume and ultra thick base concrete, the concreting of underground foundation at present has 80% to be accomplished by concrete mixer.Though the pump truck mobility is high on the market, restriction is highly received in pumping.The pump truck that this is highly high with regard to a kind of pumping of active demand, price is low, rotation is flexible, work is wide, pumpability is strong, mobility is strong is simultaneously, higher to the performance requirement on car load chassis.
Summary of the invention
The purpose of the utility model is according to the development of boom type concrete mixer and market, has overcome the defective of prior art, discloses a kind of dress power arm posture concrete pump truck of going up.
The utility model is achieved in that a kind of dress power arm posture concrete pump truck of going up; Comprise chassis, dynamical system, articulated boom system, pumping system, hydraulic system, electrical system and four swing telescopic outriggers, it is characterized in that: described dynamical system is provided with engine in situ and last mounted engine; Engine in situ provides the driving dynamics of carrying pump truck; Last mounted engine is installed on the vehicle frame of top, pump truck trailing wheel chassis, and the hydraulic power of pumping system, articulated boom system is provided.Said hydraulic system adopts main oil pump and electromagnetic valve group in current and master cylinder to be connected to become major loop, at the main oil cylinder piston side commutation sensors that receives main oil cylinder piston bar commutation signal is set, and commutation sensors and main oil pump circuit are controlled by controller.Said electrical system wiring connects for the CAN bus.
The beneficial effect of the utility model is: the power of pumping of concrete no longer power taking has been cancelled the transfer case device of conventional arm posture concrete mixer in engine in situ, need not vehicle bridge to be changed a social system again; Pumping power comes from mounted engine, and engine in situ is shut down during pumpdown.Because the power ratio engine in situ of last mounted engine is much little, so the work oil consumption significantly reduces, only go and carry usefulness in existing chassis of using, and the technical performance on chassis is required to decrease.The utility model product is compared with the prior art concrete mixer with the money model, and manufacturing cost obviously reduces, and the working oil consumption descends nearly 30%.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, chassis; 2, articulated boom system; 3, conveyance conduit; 4, pumping system; 5, oil pump group; 6, go up mounted engine; 7, swing telescopic outrigger; 8, dynamical system.
The specific embodiment
According to accompanying drawing; Dress power arm posture concrete pump truck on the utility model comprises chassis 1, articulated boom system 2, conveyance conduit 3, pumping system 4, oil pump group 5, goes up mounted engine 6, swing telescopic outrigger 7, dynamical system 8 and hydraulic system, electrical system.Dynamical system 8 is provided with engine in situ and last mounted engine 6.Engine in situ provides the driving dynamics of carrying pump truck, and last mounted engine 6 is installed on the vehicle frame of 1 top, pump truck trailing wheel chassis, drives 5 work of oil pump group, for pumping system 4,2 work of articulated boom system provide essential hydraulic power.
Hydraulic system adopts main oil pump and electromagnetic valve group in current and master cylinder to be connected to become major loop, at the main oil cylinder piston side commutation sensors that receives main oil cylinder piston bar commutation signal is set, and commutation sensors and main oil pump circuit are controlled by controller.The electrical system wiring connects for the CAN bus.
The utility model is on the basis of existing boom type concrete pump truck; The transfer case of cancellation engine in situ; In that mounted engine 6 and 4 work of oil pump group 5 driving pumping systems are set on the vehicle frame, concrete is delivered to the cast position through conveyance conduit 3 through directly.Solved the boom type concrete pump truck to chassis whole performance requirement height and the high problem of use cost, had very strong practicality, can promote widely and use in the construction machine.
