Description
Technical field
The utility model relates to the up-to-date technology of self-closed horizontal layout mixing transportation under a kind of rotary state, particularly relates to a kind of mixing transportation of engineering machinery field.
Background technology
Concrete mixer truck is comprised of car chassis and concrete-agitating special purpose device, and commitment is Germany and Japanese proprietary technology, is the tilting slewing arrangement.The product of present Chinese Mixer Truck manufacturer has the technical characterstic of oneself, but is all to research and develop on the design basis of these two kinds of tanks.Its special mechanism mainly comprises drive system, underframe support, tank body, charging/discharging device, steering unit, washing system etc.Principle of work is the controllable capacity pump by the power of car chassis output drive hydraulic system principle by power takeoff, mechanical energy is converted into to hydraulic energy and passes to fixed displacement motor, motor drives reductor again, drive mixing device by reductor, by the tank body internal helical blades, ceaselessly rotate, make material in tank keep its homogeneity, and drive the material discharge process that turned round when discharging.
The concrete mixer used in the market is centrum shuttle type tilting device, mixer barrel high spud angle (10 °-20 °) design, the efficient loading capacity is 60%, during vehicle operating, tank body will rotate around the tank body axle center, the upset of drive cement concrete, its center of gravity departs from car load line of centers 50～100mm towards the mixer barrel rotation direction, and the adverse effect that increases side direction roll force that force of inertia produces is arranged; The weight of tank body and delivery material thereof is shared by reductor and support roller, and reductor is effectively fixing, and the raceway be connected on tank body is but to be placed on tugboat, by support roller, supports the raceway rotation.Due to upper and lower abrupt slope, the jolt complex characteristics of the building site road conditions such as road surface of tilted road surface and hollow, it will bear tank body and delivery weight of material and from the inertial impact force of all directions, limit the support that tank body breaks away from roller, to reduce to the damage of reductor and tank body with to the impact of support roller, unique method is, in the raceway outer, the raceway band is set, two ends connect sub frame by bolt and fix, prevent that tank body breaks away from and beats, but still do not resist tank body and deliver weight of material inertia impact huge while moving, the inertia impact particularly produced due to emergency brake vehicle loading fluid, all acting on tank body turns and is added on reductor, if Vehicular turn slightly has inclination, the tank body rear portion will break away from support roller, the inertia impact of potential safety hazard can not effectively fixedly share to(for) the tank body rear portion is very fearful.
