Description
Technical field
The present invention relates to a kind of road maintenance equipment, specifically a kind of pavement cutting machine heat sink.
Background technology
Pavement cutting machine is equipment conventional in road maintenance engineering, is mainly used in the joint-cutting on road surface, repairing.Because rigid pavement intensity is larger, in cutting process, cutting blade and pavement friction can produce a large amount of heats, cooling make the temperature of the cutting blade on cutting machine and cutting machine rotating shaft higher, if greatly will affect the cutting efficiency of cutting machine and the application life of cutting blade and rotating shaft not in time.In existing pavement cutting machine, generally adopt the mode of water-cooled cooling, the water in water tank is sprayed directly on to front portion or the rear portion of cutting blade by conduit, but the cooling-down effect of this mode not obvious, and its reason is as follows:
First, in cutting machine traveling process, cutting blade is that clockwise High Rotation Speed road pavement is cut, cutting blade and the severe friction heat production of road contact position, then rotate and depart from road surface, therefore the temperature at cutting blade rear portion is apparently higher than the temperature of front portion, if carry out spray cooling to the front portion of cutting blade, then effectively can not reduce the temperature at the higher cutting blade rear portion of temperature, not reach the object into cutting blade cooling;
The second, the water of existing pavement cutting machine is sprayed onto on cutting blade with the form of sub-thread current, less with the contact area of cutting blade, and fix due to water spraying direction, cutting blade exists the blind area of water spray, makes non-uniform temperature on cutting blade, have a strong impact on the application life of cutting blade;
3rd, existing pavement cutting machine to the rotating shaft of cutting machine and cutting blade spray cooling simultaneously, cannot affect the use of cutting machine rotating shaft;
4th, during cutting blade cutting road surface, generation heat mainly comes from the position that cutting blade contacts with road surface, and existing pavement cutting machine cannot be lowered the temperature to this position.
Summary of the invention
The object of this invention is to provide a kind of heat sink for pavement cutting machine, effectively can reduce the temperature of cutting blade, can be again simultaneously the rotating shaft cooling of cutting machine and the frictional heat reducing itself and ground when cutting blade cutting road surface.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of pavement cutting machine heat sink, comprise the water tank be arranged on cutting machine, booster pump and water injector, described water injector comprises sparge pipe I and sparge pipe II, the delivery port of water tank is connected with booster pump water inlet pipe, booster pump outlet pipe connects the sparge pipe I led in cutting blade face shield and the sparge pipe II be arranged at outside face shield respectively by threeway, water in water tank passes through the pressurization of booster pump by described distributing T-pipe, be ejected into through sparge pipe I on the position and rotating shaft cutting blade being pressed close to cutting machine rotating shaft respectively and be ejected into the operate portions on cutting blade cutting road surface through sparge pipe II, described sparge pipe I arranges the shower nozzle that two lay respectively at cutting blade both sides, shower nozzle is arranged multiple hole for water spraying.
Further, hole for water spraying on described shower nozzle is divided into central hole for water spraying and edge hole for water spraying, central authorities' hole for water spraying is arranged on the middle position of shower nozzle, current spray perpendicular to shower nozzle, edge hole for water spraying is arranged around central hole for water spraying, current are tilted to outside shower nozzle and spray, and a part of current can be ejected in the rotating shaft of cutting machine.
Further, described sparge pipe II is fixedly installed on the lower edge of cutting blade face shield, the tube wall of sparge pipe II is offered aperture along the longitudinal direction that the supply water watering trough of ejection or a tube wall for sparge pipe II are offered multiple water spray, makes the water in sparge pipe II be ejected into the operate portions on cutting blade cutting road surface.
Compared with the heat sink of existing pavement cutting machine, the present invention has following beneficial effect:
The first, by the use of booster pump, hydraulic pressure increases, larger from the water velocity of sparge pipe ejection, while reduction cutting blade temperature, can effectively remove the impurity that cutting blade adheres to, and can reduce water supply volume, saving water resource;
Second, at cutting blade face shield arranged outside sparge pipe II, in order to the operate portions spray cooling to cutting blade cutting road surface, the heat produced because of cutting rubbing can be reduced to a great extent, the rising of temperature on cutting blade is controlled from source, also be the basis that the further spray cooling of sparge pipe I is laid simultaneously, improve cooling-down effect;
3rd, sparge pipe II longitudinally arranges watering trough along tube wall, the cascade that width is larger can be sprayed, have larger contact area with cutting blade, more effectively reduce the frictional heat of cutting blade in the process of cutting road surface;
4th, the shower nozzle on sparge pipe I is divided into the both sides of cutting blade, can to the two-sided spray cooling of cutting blade, and described shower nozzle is arranged the hole for water spraying in different water outlet direction, the water of ejection and cutting blade can be made to have larger contact surface, and distribution is more even, improves cooling-down effect;
5th, current are through the hole for water spraying dispersion ejection of sparge pipe I upper nozzle, while spray cooling is carried out to cutting blade, wherein a part of water flow jet is in the rotating shaft of cutting machine, the rotating shaft of transferring temperature rising because of high-speed rotary can be lowered the temperature, and then reduce the fault rate of rotating shaft and extend its application life.
Therefore, the present invention, by reducing the quantity of heat production of cutting blade cutting road surface process and increasing current and cutting blade contact area, effectively reduces the temperature of cutting blade, can reduce again the temperature of cutting machine rotating shaft simultaneously, extend the application life of cutting blade and rotating shaft, improve the cutting efficiency of cutting blade.
