Description
Technical field
The present invention relates 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 and hits pile body.
Traditional hydraulic pile hammer is that hammer body and the hammer core in hammer body, the top of hammer body are connect 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 which external in hammer body is arranged wear rib, however hammers into shape
Core is easy in use and causes to rub inside hammer body, and prolonged friction not only results in hammer core and is damaged, while also can
Cause it is thinning inside hammer body, the case where to influence its stress intensity, be susceptible to 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, will have a direct impact on 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, cannot achieve expected piling effect, while can also cause certain damage to hammer body.It should
Technical barrier is always the direction of technical field technical staff research and development.
Invention content
In view of the deficiencies of the prior art, the present invention provides a kind of resistance reduced when impacting, prevent hammer core and hammer
The hydraulic pile hammer of body abrasion, easy access.
To achieve the above object, the present invention provides following technical solutions：A kind of hydraulic pile hammer includes hammer body and place
It is for the placement of hammer core and mobile space, the hammer body in that can have along the hammer core of hammer body axial displacement, hammer body in hammer body
Axial one end of columnar framework, the framework is connecting pin, and the other end is punching press end, it is characterised in that：The punching press of the hammer body
It connect, bores with hammer body equipped with the staking punch being fixedly connected with hammer body and cross section is tapered, the taper big end of the staking punch at end
Shape small end extends towards hammer body outside；External its axial direction of end face upper edge of the framework offers climbs for operating personnel
Several openings；The inner wall of the framework is equipped with the wear rib being detachably connected with it；Being equipped in the middle part of framework can induction hammer core
And with the protective device that can send the signal to external hydraulic system and promote its start and stop.
Using above-mentioned technical proposal, it sets staking punch to taper, promotes the area at the punching press end of hammer body to reduce, to subtract
Resistance when punching press is lacked, the effect when hydraulic pile hammer being made to implement piling is more preferable and simple in structure；By in framework
Several openings are arranged in outside, and when operating personnel need to implement it maintenance, the position overhauled to needs can be climbed by the opening,
Without, by being removed on arm, saving the repair time by other tools or by pile hammer, having saved production cost；Pass through
Wear rib is set on the inner wall of framework, when hammer core, which is in space, to be moved, directly will not cause to rub with framework inner wall, it is right
Hammer core and framework provide protection, extend its service life, and disassembly and assembly structure is simple；The setting of protective device can be to cone core reality
Detection is applied, during implementing to drive piles, hammer core tenesmus, if the protective device is not sensed by cone core at this moment, then protective device
External hydraulic system is sent a signal to, promotes to hammer core into shape and hammer body is stopped, hammer body is implemented to protect, while also can avoid shadow
It rings to piling effect.
The present invention is further arranged to：Staking punch includes at least two sections of diminishing conically shapeds of angle, conically shaped with
It is connected respectively by flanged plate and fastener between hammer body and conically shaped and conically shaped.
Using above-mentioned technical proposal, setting in this way can reduce the length of each conically shaped in staking punch, to promote to make it have
The stress intensity of bigger prevents deformation or damaged.
The present invention is further set as：The cross section of framework is rectangular, and framework includes the side of four interconnections,
It is connected respectively by rectangle connection strap between four sides, the wear rib is installed on the rectangle connection strap by fastener
On.
Using above-mentioned technical proposal, it is arranged so easy to process, simple in structure, wear rib is on rectangle connection strap and dismounts
It is convenient.
The present invention is further set as：Opening is rectangular aperture.
Using above-mentioned technical proposal, personnel's climbing easy to operation is set in this way and is trampled.
The present invention is further set as：Hammer body is located at is evenly equipped with several convex ribs with the joining place of staking punch.
Using above-mentioned technical proposal, the stress that setting can promote the joining place of hammer body and staking punch that can bear bigger in this way is strong
Degree.
The present invention is further set as：Protective device includes the installing frame being fixedly arranged in framework and is set up in installation
Sensor in frame.
Using above-mentioned technical proposal, such setting structure is simple, convenient for disassembly and assembly, and protective device can be prevented by framework
It falls off.
The invention will be further described below in conjunction with the accompanying drawings.
