Hydraulic two-way recooling type heat dissipation type hydraulic hammer
The invention discloses a hydraulic two-way recooling type heat dissipation type hydraulic hammer, and belongs to the technical field of heat dissipation treatment of hydraulic hammers. Cooling liquid is supplied to the upper end part and the lower end part of a liquid storage cavity through a water cooling box; and by utilizing the principle that a piston drives a drill rod and a movable sleeve to move up and down in a reciprocating mode, the cooling liquid supplied to the lower end part of the liquid storage cavity is extruded when the movable sleeve moves downwards, so that the cooling liquid is guided into a drainage cavity through a perfusion hole and flows through a connecting tenon body and overflows through a spraying hole, and therefore, on the one hand, a drill rod and a drill hammer head are cooled, and on the other hand, the sprayed cooling liquid plays a dust falling role; and when the movable sleeve moves upwards, on the one hand, the cooling liquid is supplied to the lower end part of the liquid storage cavity through a negative pressure, and on the other hand, the cooling liquid at the upper end part of the liquid storage cavity is pressed into a recooling cavity and wets multiple refrigeration bag rods, the cooling liquid and the recooling cavity cooperate with each other so that the cooling effect on the hydraulic cavity can be improved; after the movable sleeve retreats, the cooling liquid in the recooling cavity synchronously retreats; circulation is conducted in this way; and therefore, two-way water cooling is achieved through hydraulic reciprocating motion.
本发明公开了一种液压双向回冷式散热型液压锤，属于液压锤散热处理技术领域，通过水冷箱对储液腔上下端部补给冷却液，利用活塞带动钎杆连同活动套上下往复运动原理，活动套向下运动时，对储液腔下端部补给的冷却液进行挤压，使得冷却液通过灌流孔导入至引流腔，并流经接榫体通过喷覆孔溢出，一方面对钎杆、钎锤头进行降温，另一方面喷覆而出的冷却液起到降尘作用，活动套向上运动时，一方面利用负压为储液腔下端部进行冷却液补给，另一方面将储液腔上端部的冷却液压入回冷腔并浸湿多个制冷囊棒，两者相互配合，以提高对液压腔起到降温作用，在活动套回退后，回冷腔内部的冷却液同步回退，以此循环，通过液压往复运动实现双向水冷降温。
