Description
Technical field
The utility model is related to a kind of engineering machinery, more particularly to a kind of hydraulic pile hammer.
Background technology
Hydraulic pile hammer belongs to impact type pile hammer, pile body is mainly hit by way of freely falling body, and can lead to
After crossing hydraulic system promotion desired height, acceleration energy is obtained from hydraulic system to improve impact velocity strike pile body.
Traditional hydraulic pile hammer is connect for hammer body and the hammer core in hammer body, the top of hammer body with hydraulic system, separately
One end is the working end for implementing strike with pile body.The working end of hammer body is consistent with hammer body cross section, and the area of cross section is got over
Greatly, resistance is bigger, for large-scale pile hammer, how to reduce its resistance during piling neck always
The problem that field technique personnel can not overcome.
Hammer body is worn in use in order to prevent, it will usually in the external setting wear rib of hammer body, however be hammered into shape
In use easily with causing to rub inside hammer body, prolonged friction not only results in hammer core and is damaged, while also can core
It causes hammer body inside thinning, so as to influence its stress intensity, is susceptible to the situation of deformation.
The volume of hydraulic pile hammer is larger, when being in use state, is suspended on arm, at this point, right if necessary
When it implements maintenance, operating personnel need to take by removing on arm, can directly influence project progress it.Or pass through
Aerial ladder is set up, makes operating personnel that can implement to overhaul to pile hammer, however the carrying of aerial ladder and use undoubtedly increase engineering cost.
Therefore, how quickly to implement maintenance to impact cone is always the problem that field technology personnel can not overcome.
In use, hammer core is implemented to be promoted by hydraulic system to it, then hammers core into shape by release, and hammer core drives hammer
Body fast ram pile pipe implements piling, if hammer core is not run during release to the position that can implement shock with hammer body,
Then the impact force of pile pipe can be reduced, can not realize expected piling effect, while certain damage can be also caused to hammer body.It should
Technical barrier is always the direction of technical field technical staff research and development.
