Description
Technical field
The invention belongs to municipal to maintain equipment technical field, specially a kind of municipal works handle vehicle with road ponding.
Background technique
Existing road is broadly divided into common stone road, cement concrete road, bituminous concrete highway and regeneration asphalt
Four kinds of concrete road, these pavement of road due to often being rolled by underground water, rainwater, traction engine, the shadows such as extraneous natural cause
The road hole for often occurring being recessed is rung, these recess road holes are easy ponding on rainy day, when the distance hole that motor vehicle ran ponding will
There is the case where The water splash in all directions, thus will affect pedestrian, non-motor vehicle and the motor vehicle normally travel on side, and the road that is recessed
The ponding in hole is handled not in time, can accelerate the damage of pavement of road in the case where traction engine rolls, to increase road maintenance
Cost, usual these Roads hole ponding mainly passes through manually cleaning or large area ponding to be completed using water pump cleaning, due to one
A little lesser pit-hole limited areas, cleaning are inconvenient to implement, usually by manually using the processing of tools bit by bit such as spade, no
Operating efficiency is only greatly reduced, while maintenance personnel is on road for a long time, is easy to happen accident, is absolutely unsafe, because
This is it is proposed that a kind of municipal works handle vehicle with road ponding.
Summary of the invention
It is an object of the invention to: in order to solve existing road hollow ponding processing inconvenience, low efficiency, personnel are for a long time
The problem of resting on road, being absolutely unsafe provides a kind of municipal works road ponding processing vehicle.
The technical solution adopted by the invention is as follows:
A kind of municipal works road ponding processing vehicle, including chassis, the chassis is equipped with suction box, suction box
Top is equipped with water spray chamber, and water spray chamber upper top position is equipped with high-pressure hydraulic pump, and right positions are equipped with water suction on the chassis
Pump, pulsating pump are connected by being connected to water pipe with suction box, are connected with hose on pulsating pump, and hose is from chassis bottom interposition
Stretching is set, right end position is equipped with bracket on the chassis, is equipped with sparge pipe on bracket, is equipped with high pressure spray on sparge pipe
Head；
The sparge pipe is connected by high-pressure water pipe with high-pressure hydraulic pump, and high-pressure hydraulic pump is connected with water spray chamber, the vehicle bottom
The battery group of driving high-pressure hydraulic pump and pulsating pump running is also equipped on disk, the water spray chamber is set with right positions on suction box
There is the Duct fixing clamp of fixed high-pressure water pipe, left and right sides position is separately installed with traveling wheel, the chassis on the chassis
Upper bottom portion corresponds to traveling wheel position and is equipped with damper, and the bottom of the damper is fixed with shaft set, is equipped in shaft set
The shaft being connect with traveling wheel.
Wherein, the chassis upper bottom portion corresponds to hose position and is also equipped with winder, and hose is wound on winder.
Wherein, the suction box and water spray chamber upper left side position are mounted on liquidometer.
Wherein, filtering head is installed far from pulsating pump one end on the hose, is equipped with and filters far from hose one end in filtering head
Net.
Wherein, left end is connected with fixed link on the chassis, and separate chassis one end is equipped with handrail in fixed link.
Wherein, insulation sleeve is installed on the handrail.
Wherein, the insulation sleeve is equipped with anti-skid chequer.
Wherein, it is connected separately with fixed block on two parts up and down of the damper, runs through between fixed block and is equipped with stock,
The both ends of stock are respectively equipped with limited block.
In conclusion by adopting the above-described technical solution, the beneficial effects of the present invention are:
1, in the present invention, by the way that pulsating pump is arranged, the ponding at pot hole is drawn into suction by hose by pulsating pump
In water tank, solve it is traditional by hand sweeping low efficiency, while clean personnel for a long time rest on road, have it is very high
Security risk problem, and the filtering head by having strainer in the installation of the end of hose, avoid rubble etc. when aspirating ponding
Sundries, which is inhaled into the pump housing, influences the case where pulsating pump is safely operated, and improves practicability.
2, in the present invention, the water in water spray chamber is sprayed by the way that water spray chamber is arranged, and by the high-pressure nozzle of setting, high pressure
Spray head is directed at road surface, using the chewing gum or greasy dirt of the dirty such as adherency of the stubbornness of high pressure water cleaning road, compensates for large-scale clear
Carwash clean range is wide, not sufficiently effective disadvantage, and cleaning draining is neglected neither, and greatly improves the integral loop in practicability and city
Border is clean and tidy.
3, in the present invention, it can more be suitable for uneven that traveling wheel is connect by damper with chassis when walking
Road surface, keep the whole machine balancing of car body, avoid jolting due to road injustice when rigid connection and placing injustice, influencing pulsating pump just
The case where often working, also avoids because of risk of tumbling caused by jolting.
4, in the present invention, structure is simple, small in size, light-weight, easy to operate, while manufacture is low with maintenance cost, for road
Road hollow ponding processing speed is fast, has great popularization value.
