Abstract

The utility model discloses a heat sink of a hydraulic excavating machine, which includes a radiator and is characterized in that an automatic spraying system is arranged and mainly comprises a water tank, a control valve, a water pump, at least two spraying heads, a water temperature sensor and a controller. A water outgoing pipeline of the water tank is communicated with the spraying heads through the control valve and the water pump, the spraying heads are arranged above the radiator, the output of the water temperature sensor is connected to the controller, and the output of the controller is connected to a control end of the control valve. The heat sink of the hydraulic excavating machine can be designed according to normal temperature environment, and reduces the difficulty in design and the cost of the radiator; when the heat sink is used in an occasion at a too high temperature, the automatic spraying system is started after the water temperature sensor senses that the water temperature of the excavating machine is high, so that the temperature reduction effect can be achieved, and the heat dissipation effect is ensured; moreover, obstructions on the radiator can be washed away, thereby avoiding the trouble that mosquitoes block the core body of the radiator in summer.

Description

The hydraulic crawler excavator heat abstractor
Technical field
The utility model relates to a kind of accessory of excavation machinery, is specifically related to a kind of heat abstractor that is used for hydraulic crawler excavator, adopts air-cooled and water spray combination realization heat radiation.
Background technology
The cooling system of hydraulic crawler excavator is made of engine water jacket, water pump, water radiator, fan, hydraulic oil radiator and cooling air channel usually, water pump drives heat transfer medium water and circulates by force, at the water radiator place, by the fan air draught, air-flow flows through from spreader surface, takes away heat.
The common operating mode of hydraulic crawler excavator is complicated abominable, is operated in that often heat balance is not up to standard under the environment of high temperature.Especially during the broiling summer, mosquito etc. are inhaled into the radiator core, can block radiator with dust, various fragments etc., and cause intake to reduce, the influence heat radiation, situation such as the water temperature height takes place, boil, and cause the excavator cisco unity malfunction.
In order to adapt to the working environment of high temperature, main engine plants often design radiator according to limit high temperature, and the radiator volume is big, cost is high, have also increased the complete machine weight of hydraulic crawler excavator simultaneously.
Summary of the invention
The utility model purpose provides a kind of hydraulic crawler excavator heat abstractor, under the situation that does not increase the radiator integral volume, solves the too high problem of engine water temperature, makes heat abstractor be applicable to that various complex working conditions use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hydraulic crawler excavator heat abstractor, comprise radiator, be provided with automatic sprinkler fire-extinguishing system, described automatic sprinkler fire-extinguishing system mainly is made up of storage tank, control valve, water pump, 2 drencher heads, cooling-water temperature sensor and controllers at least, the outlet conduit of storage tank is communicated to described drencher head through control valve and water pump, described drencher head is positioned at the top of radiator, the output of cooling-water temperature sensor is connected to controller, and the output of controller is connected to the control end of control valve.
Further technical scheme, described control valve is an electromagnet cut off valve.
Above, cooling-water temperature sensor and controller can be shared with other device of hydraulic crawler excavator, cooling-water temperature sensor is used for the detection of engine water temperature, controller is used to the action that judges whether to open spray system and handle control valve, can be provided with and realizes above-mentioned functions by increase software in the controller of existing hydraulic crawler excavator.
The utility model operating principle is: under the normal condition, radiator adopts the air cooling way heat radiation, by with the supporting fan of radiator air being flowed, takes away heat; Cooling-water temperature sensor provides water temperature signal, preestablish a threshold value in the software of controller, when detecting water temperature and be higher than preset threshold, controller sends signal, the control valve action is opened, water in the storage tank is driven by water pump and is transported to each drencher head, and water is sprayed onto on the radiator, plays the effect of cooling cooling.
Also can further add water filtration and cooling unit in this device, through the water of spray, water temperature raises, and water quality is dirty, utilizes water filtration and cooling unit, can recycle, and realizes water saving, but can increase installation cost.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, because the utility model is provided with automatic sprinkler fire-extinguishing system in heat abstractor, the excavator radiator can design by normal temperature environment, has reduced the cost of design difficulty and radiator; When using in the too high occasion of environment temperature, when perception excavator water temperature was high, automatic sprinkler fire-extinguishing system can start, and plays cooling effect, guaranteed radiating effect.
2, automatic sprinkler fire-extinguishing system of the present utility model in cooling, can be rinsed the obstruction of radiator well, has avoided the worry of mosquito obstruction in summer radiator core body.
3, cooling-water temperature sensor of the present invention can be used the cooling-water temperature sensor that motor carries, and utilizes controller for excavators to realize signal transmission and control, is convenient to implement.
Description of drawings
Fig. 1 is the structural principle schematic diagram of the utility model embodiment one.
Wherein: 1, storage tank; 2, control valve; 3, water pump; 4, drencher head; 5, cooling-water temperature sensor; 6, controller; 7, radiator.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to shown in Figure 1, a kind of hydraulic crawler excavator heat abstractor, constitute by radiator 7 and automatic sprinkler fire-extinguishing system, automatic sprinkler fire-extinguishing system comprises storage tank 1, control valve 2, water pump 3,3 drencher heads 4, cooling-water temperature sensor 5 and controllers 6, the outlet conduit of storage tank 1 is communicated to described drencher head 4 through control valve 2 and water pump 3, drencher head 4 is positioned at the top of radiator 7, and the output of cooling-water temperature sensor 5 is connected to controller 6, and the output of controller 6 is connected to the control end of control valve 2.
In the present embodiment, control valve 2 adopts electromagnet cut off valve; The cooling-water temperature sensor that cooling-water temperature sensor 5 adopts motor to carry, controller 6 adopts controller for excavators; The number of drencher head can be provided with as required, is provided with 3 drencher heads in the present embodiment.
When detecting the high signal of water temperature, electromagnet cut off valve is opened, and the water of storage tank is transported to each drencher head by water pump, to radiator water spray, cooling; It is normal that water temperature is recovered, and electromagnet cut off valve is closed, and drencher head stops water spray.
