Description
Technical Field
The utility model relates to a crawler pile driver makes and construction technical field, concretely relates to flexible crawler pile driver of stand.
Background
At present, in building construction, pile foundation construction equipment is often used, the existing pile foundation construction equipment comprises a rotary drilling rig, a long spiral drilling rig, a hydraulic pile driver and the like, and a working device matched with the equipment usually adopts a parallelogram and small triangle support structure or a large triangle structure, but the equipment has the problems that an upright post cannot lift, the upright post is inconvenient to adjust, an erection oil cylinder is difficult to install, the stability of the whole machine is poor and the like.
In order to solve the technical problem, my designed patent 201610514791.9 discloses a lifting mechanism for a pile driver upright post, which comprises a lifting oil cylinder, a sliding seat, a pulling oil cylinder, a supporting piece and a rotary disc; the upright post of the pile driver is slidably mounted on the support piece, the sliding seat is slidably mounted on the upright post of the pile driver, the rotary disc is rotatably mounted on the body of the pile driver, and the support piece is mounted on the rotary disc; one end of the erecting oil cylinder is rotatably arranged on the machine body of the pile driver, and the other end of the erecting oil cylinder is connected to the sliding seat; one end of the pulling oil cylinder is connected to the sliding seat, and the other end of the pulling oil cylinder is connected to the supporting piece. When using this pile driver stand to rise a frame mechanism, the stand is placed vertical the process of rising of placing by the level as follows, the rotation and the concertina movement of the hydro-cylinder of rising, the slip relation of the hydro-cylinder of cooperating simultaneously and sliding seat and stand for the stand becomes the tilt state by the horizontality, for making the stand become vertical state by the tilt state faster, this moment, should make and draw the hydro-cylinder shrink of rising, the shrink that draws the hydro-cylinder makes the sliding seat slide on the stand, finally make the quick vertical state that becomes of stand.
The drawing oil cylinder that this patent scheme set up can effectual improvement speed of rising and the straightness that hangs down of quick adjustment stand, has solved the problem of the stand side to side beat that the in-process of rising appears because of two hydro-cylinders of rising are asynchronous, has increased the security and the stability of the in-process of rising. The lifting oil cylinder is arranged, the height of the upright column is adjusted when the lifting oil cylinder rises upwards, the upright column can be contacted with the ground when the lifting oil cylinder descends, the effect of stabilizing the whole pile driver is achieved, or the lifting oil cylinder is matched with the rear support leg of the pile driver to jack the pile driver together, so that the crawler belt of the pile driver can stretch conveniently. The height of the upright post can be increased, and longer piles can be hit by the upright posts with the same length.
However, the distance that the upright post of the crawler pile driver provided by the above patent extends forwards is limited, and the upright post can only extend forwards within 0.5 m of the machine body generally according to the length of the cantilever of the hinged connection structure, and the adjustment of the machine body is usually performed by moving the crawler and the long and short boats, so that the upright post is adjusted to be aligned with the pile position.
However, in many large-scale construction sites, since the working surface of the pile driver construction site is complicated, for example, when the pile driving working surface of the construction site is a cliff, a river bank, an ocean or other tracks and pile positions are at different elevations, the distance between the upright post extended by the pile driver and the pile position is often greater than 1 meter, and in order to ensure the safety of the pile driver, the upright post cannot reach the pile position only by adjusting the body with the tracks or the long and short boats, so that the pile driving construction cannot be performed. Along with the construction of more and more overwater, offshore and super high-rise buildings, the construction operation requirement that the pile position is far away from the pile driver body is more and more, and the existing pile driver and the pile driving operation method can not meet the requirement.
In addition, since the pile driver has a large volume and weight, when the column is integrally extended forward and away from the pile driver body, the inclination of gravity causes the overall center of gravity of the pile driver to move forward, which easily causes the pile driver to lose its original balance and affect the alignment of the pile position or even more seriously topple the pile driver. When the whole upright post extends forwards for a long distance, the problem that how to adjust the gravity center of the pile driver to keep balance is not considered when the upright post extends forwards for a long distance to work is solved.
In summary, the existing technical solutions can not solve the technical problem of making the upright post extend forward for a long distance to perform reliable and safe piling construction.
