Description

The horizontal concrete agitator truck
Technical field
The utility model relates to the engineering loader transporter vehicle, especially a kind of horizontal concrete agitator truck.
Background technology
Concrete mixer truck is the main transportation device of concrete transportation in engineering construction, concrete mixer truck on home market generally adopts the conventional confguration pattern, namely stirring the tank body front end is connected rear by bearing support before subframe with reductor, the raceway of tank body is stirred in rear end by 2 support roller supportings on the subframe rear support, form 3 supporting structure tiltings and install, motor driving stirs the tank body rotation and realizes the concrete-agitating mode.There is following problem in the tradition Mixer Truck:
(1) the car load height dimension is difficult to control, and is prone to superelevation.The self-propelled vehicle safe and technical specification GB7258 of country regulation transport vehicle height overall is no more than 4m, and generous amount Mixer Truck major part all transfinites, and is bad by performance.
(2) the car load center of gravity is high, to Vehicle Driving Cycle, brings serious potential safety hazard, easily overturns while turning especially, directly endangers chaufeur and passerby's safety.
(3) the stirred pot plot ratio can only reach 65% left and right, and transport economic specific property is not high.
(4) when making generous amount Mixer Truck, only have to lengthen and stir tank body, the lengthening of stirring tank body causes moving after the raceway bearing position, make it to middle back axle centre distance increase, the moment of flexure of subframe increases, cause subframe girder generation plastic deformation, fracture of frame even occurs, this is the common failure mode of Mixer Truck.In order to prevent subframe girder generation plastic deformation, need to improve the load-carrying capacity of associated components, certainly will increase complete machine weight, cause manufacturing cost increase, oil consumption increasing and carrying capacity to reduce.
(5) segregation phenomenon is difficult to control, and can not fundamentally eliminate concrete segregation phenomenon.Why cement concrete will keep prolonged agitation in transportation, will make exactly cement concrete not produce segregation, otherwise just can not use.Thereby the Mixer Truck of existing structure form is to lean on the rotation of cylindrical shell to drive concrete stirring,, for cement concrete, belongs to the stirring of indirect form, so there is the problem of ' segregation ' all the time in the Mixer Truck of existing structure form, just degree varies in size.
Its helix line and difficult parameters to be to meet design requirement when (6) blade was made, and measure and check difficulty.Blade and cylindrical shell are by being welded to connect, and thermal deformation is larger in welding process.On the other hand, almost can't change after blade wear, the maintainability of blade is poor.
For above problem, new problem has been proposed for the improvement of Mixer Truck.
At present, generally adopt and reduce stirring tank body degree of dip and remove subframe and use two kinds of optimal way of chassis special:
A kind of is to adopt reduction to stir the tank body degree of dip to reach the purpose that reduces car load height, car load center of gravity.This kind mode has just been revised stirring tank body degree of dip simply, by reducing degree of dip, reaches reduction car load center of gravity, and the stirring structure form of itself does not change, and still utilizes the stirring tank body to rotate to stir.
Another kind is to adopt to remove the purpose that subframe reaches reduction car load height, car load center of gravity with chassis special and prevents the vehicle frame distortion.Although this kind mode has certain advantage on the generous amount Mixer Truck of manufacturing, but still fails to tackle the problem at its root.
Summary of the invention
For the prior art above shortcomings, the purpose of this utility model is to provide and a kind ofly can reduces car load height and center of gravity, raising plot ratio, can guarantee again that vehicle frame is indeformable, the concrete material is not emanated and technical scheme easy to maintenance in transportation.Adopt tank body fully horizontally-arranged, with the angle on plane on vehicle frame be that the zero degree tank body is fixed, blade rotation, but the horizontal concrete stirring movement car of the angle of 10 °-15 ° of tank body liftings during discharging.
the technical solution of the utility model is achieved in that and comprises chassis, lifting device, mixing device, subframe, tank body, trip shaft, be connected with U-bolt between aforesaid chassis and subframe, be placed with tank body on subframe, the both sides outside weld of tank body rear end is connected to overturning seat, trip shaft passes the hole of overturning seat and the hole of subframe rear end successively, the tank cylinder two ends of tank body are welded with respectively tank body front head and tank body rear head, the input shaft of the HM Hydraulic Motor connection reducer of its mixing device, the output shaft of retarder and shaft one end spline joint, the other end of shaft inserts the axis hole of bearing seat A successively, the hole of tank body front head, the hole of stirring vane assembly, the hole of bracing frame, the axis hole of the hole of tank body rear head and bearing seat B, bracing frame and tank body inner top are welded to connect, the elevating ram undersetting of aforesaid lifting device is welded on subframe, and the tank body front head is welded with the elevating ram upper bracket, is connected with elevating ram between elevating ram undersetting and elevating ram upper bracket, discharging mechanism is arranged at tank body rear head bottom, and feeding mechanism is arranged at the tank body top.
Also have, seal ring A is arranged between the hole of tank body front head and shaft, seal ring B is arranged between tank body rear head and shaft.
Also have, in tank body, on the shaft both sides of bracing frame, 2-8 stirring vane assembly is housed.
Further, the erection support of the charging open and close door oil cylinder of feeding mechanism is welded on the tank body top, and the piston rod of charging open and close door oil cylinder is connected with the charging open and close door, and the charging open and close door inserts in the slotted eye of feeder hopper lower end, and feeder hopper is connected with tank body welding.
