Description
Technical field
The utility model relates to hydraulic pile hammer, particularly a kind of cam is controlled the hydraulic pile hammer of commutation.
Background technology
Pile hammer is the conventional equipment of building operations.Pile hammer has good multiple types, as drop hammer, diesel hammer, vibrating hammer, hydraulic pile hammer etc.Because hydraulic pile hammer noise is little, it is flexible to pollute less, control, tonnage is large, in engineering construction, is widely used.Chinese patent ZL200910273480.8 has proposed a kind of hydraulic pile hammer without ground hydraulic station, and its compact conformation use flexibly, but its maintenance difficult, particularly large life-span of electro-hydraulic reversing valve volume is short, and impact is used.
Summary of the invention
The purpose of this utility model is to propose the hydraulic pile hammer that a kind of cam is controlled commutation.It is to adopt cam to control reversal valve commutation, realizes pile monkey commutation motion.
The utility model is to realize like this, it is comprised of hammer body, Hydraulic Station, in hammer body, be provided with hammer cylinder, tup, pallet, lift cylinder, Hydraulic Station is provided with motor, oil pump, fuel tank and hydraulic control unit, the top of hammer cylinder is connected with circular or square Hydraulic Station fuel tank bottom, the main reversing valve that it is characterized in that hydraulic control unit is that the reversal valve of being controlled by cam forms, and cam is to be driven by speed-regulating actuator.
Described cam is controlled reversal valve and is comprised of valve body, spool, upper and lower end cap, spool is arranged in the cavity being comprised of valve body, upper and lower end cap, spool bottom is provided with return spring, spool top connects valve rod, the roller contacting with cam is housed on valve rod, valve body is equipped with quadruplet arc shape oil inlet and outlet outward, has an annular oil groove on spool.
The course of work of the present utility model is such.When cam is driven by speed-regulating actuator, roller is in the height point section contact of cam, reversal valve P → A mouth is connected, oil pump is to the oil-filled lifting tup of lift cylinder, when roller runs to the low spot of cam, reversal valve P, the quick closedown of A mouth, reversal valve B → O mouth is connected, lift cylinder oil extraction, the tup strike stroke that fallen suddenly.Again again oil-filled at height point when contact section lift cylinder of cam when roller, repeat the strike that next time circulates.
The utility model is used cam to control commutation, simple in structure, long service life, and maintenance is easily.
