Description
Technical field
The utility model relates to building machinery technical fields, more specifically, it relates to a kind of pile hammer.
Background technique
In modern construction engineering application, differential settlement is built in order to prevent, and reinforce stability and antidetonation etc., it is right
In the ground of building, frequently with mode be to beat ground pile as the ground built.
It beats ground pile and needs special pile hammer, be generally made of pile monkey, pile frame and auxiliary device etc..Generally by prefabricated pile
20 meters of underground or more is driven in, when carrying out the hammering work of prefabricated pile using pile hammer, is first touched using tup, tapping is
The height for referring to that tup lifts is lower, and prefabricated pile is driven in ground, so that will not be excessive because of percussion power when tapping, cause pre-
The case where tip that stake processed enters the part of soil deviates；After the major part of prefabricated pile enters ground, weight is carried out with tup
Hammer, so that prefabricated pile is easier to enter ground.
In the prior art, it when prefabricated pile, which enters ground, reaches 15 meters or more, since subsurface pressure is larger, is touched with tup
The power tapped out has been not enough to subsequent prefabricated pile hammering into underground, and the power of bigger percussion can only be taken to hammer prefabricated pile
Underground, and percussion here is usually to lift tup, so that the power tapped out has been not enough to enter ground for subsequent dowel pin
Under, the percussion power of tup can only be changed by increasing tup weight.
However in the prior art, the maximum percussion for increasing tup is more brought by the tup used pile hammer
Power, but replace tup and need to spend longer time, influence the efficiency of work.
