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 joint-cutting, the repairing on road surface.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 cutting blade on cutting machine and cutting machine rotating shaft higher, if will greatly 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, its reason is as follows:
First, in cutting machine traveling process, cutting blade is that clockwise High Rotation Speed road pavement is cut, the violent frictional heat of cutting blade and contact site, road surface, then rotation departs from road surface, and therefore the temperature at cutting blade rear portion is apparently higher than anterior temperature, if spray cooling is carried out in the front portion of cutting blade, can not effectively reduce the temperature at the cutting blade rear portion that temperature is higher, not reach the object into cutting blade cooling;
The second, the water of existing pavement cutting machine is to be sprayed onto on cutting blade with the form of sub-thread current, less with the contact area of cutting blade, and because water spraying direction is fixed, the blind area that has water spray on cutting blade, makes non-uniform temperature on cutting blade, has a strong impact on the application life of cutting blade;
The 3rd, on existing pavement cutting machine, cannot, to the rotating shaft of cutting machine and cutting blade spray cooling simultaneously, affect the use of cutting machine rotating shaft;
The 4th,, produce heat when on cutting blade cutting the road surface and mainly come 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, can effectively reduce the temperature of cutting blade, can and in the time that cutting blade cuts road surface, reduce it and the frictional heat on ground for the rotating shaft cooling of cutting machine again simultaneously.
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 being 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 respectively the sparge pipe I of leading in cutting blade face shield by threeway and is arranged at the sparge pipe II in face shield outside, water in water tank passes through the pressurization of booster pump by described distributing T-pipe, be ejected on cutting blade, press close in the position of cutting machine rotating shaft and rotating shaft and be ejected into the operate portions on cutting blade cutting road surface through sparge pipe II through sparge pipe I respectively, two shower nozzles that lay respectively at cutting blade both sides are set in described sparge pipe I, multiple hole for water sprayings are set on shower nozzle.
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 around central hole for water spraying setting, current are tilted to the ejection of shower nozzle outside, 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, on the tube wall of sparge pipe II, offer along the longitudinal direction the aperture of offering multiple water sprays on the watering trough of the ejection of supplying water or the tube wall of sparge pipe II, make 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, in reducing cutting blade temperature, can effectively remove the impurity adhering on cutting blade, and can reduce water supply volume, saving water resource;
Second, in cutting blade face shield arranged outside sparge pipe II, in order to the operate portions spray cooling to cutting blade cutting road surface, can reduce to a great extent the heat producing because of cutting rubbing, control the rising of temperature on cutting blade from source, also the basis of laying for the further spray cooling of sparge pipe I, improves cooling-down effect simultaneously;
The 3rd, in sparge pipe II, along tube wall, watering trough is longitudinally set, can spray the cascade that width is larger, there is larger contact area with cutting blade, more effectively reduce the frictional heat of cutting blade in the process of cutting road surface;
The 4th, the shower nozzle in sparge pipe I is divided into the both sides of cutting blade, can be to the two-sided spray cooling of cutting blade, and the hole for water spraying of different water outlet directions is set on described shower nozzle, can make water and the cutting blade of ejection have larger contact surface, distribute more even, improve cooling-down effect;
The 5th, current disperse ejection through the hole for water spraying of sparge pipe I upper nozzle, when cutting blade is carried out to spray cooling, wherein a part of water flow jet is to the rotating shaft of cutting machine, can lower the temperature to the rotating shaft of transferring temperature rising because of high-speed rotary, 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.
