Description
Technical field
The utility model relates to the special-purpose vehicle technical fields of automobile industry, further relate to the self priming pump technology neck of industrial centrifugal pump
Domain.
Background technique
Since the ponding of heavy rain or other reasons can usually be given, production, life is made troubles or disaster, accumulates there is burst
When water or flood, due to the pumping equipment that spot is usually not fixed, it is therefore desirable to which mobile facility carries out Quick drainage, speedily carries out rescue work
Operation.
The existing emergency in home and abroad water drainage vehicle and movable pump station are vehicular or towed at present, and vehicle or chassis are only
As the mobile vehicle of the drainage equipment such as water pump, power needed for usual pump working is supplied by independent generator set device.
Vehicular water drainage pump truck is the chassis that the facilities such as generating set or diesel engine unit and the water pump of driving are fixed on to vehicle
On, surrounding and top closed, power is provided by vehicle-based generator set or diesel engine unit, and high equipment cost, diesel engine noise is big,
It is complicated for operation.
Towed water drainage pump truck is also referred to as pulling type water drainage vehicle, is that the dedicated units such as generating set, water pump are fixed on trailer
On, surrounding and top are closed.Water drainage vehicle cannot walk alone, other traction devices is needed to pull or transport.Its feature is
It cannot walk alone, other features are identical as vehicular water drainage pump truck
Applicant in this case once developed a kind of self-driving type pump truck, had applied for utility model patent, and title is a kind of " self-powered
The strong self-priming flood fighting water drainage vehicle of formula ", Patent No.: ZL201420515163.9, its main feature is that: the power of pump is derived from car engine
Machine, the power of engine access power takeoff by gearbox, transmission shaft, and power takeoff has an input shaft and two output shafts,
In an output shaft normally connect rear axle and drive chassis normally travel, another output axis connection and transfer tube have on power takeoff
Arrangement of clutch.When running car, the output shaft for connecting pump is detached from；Conversely, connecting rear axle when the output shaft work of connection pump
Output shaft is detached from.As shown in figure 3,91 power of engine will be conveyed to rear power takeoff by gearbox 92, power takeoff driving shaft 93
94, an output shaft of rear power takeoff 94 drives transmission shaft 95 to connect rear axle differential 96 by vehicle, and another output shaft passes through
Pump driving transmission shaft 97 connect self priming pump 98, above-mentioned power takeoff be arranged in engine 91, gearbox 92, power takeoff driving shaft 93 it
Afterwards, referred to as rear power takeoff 94.It is this by way of 94 power taking of rear power takeoff, not only influence efficiency, also add transmission shaft
