Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pile press-fitting and pulling machine, and particularly a clamp that grips piles built in parallel on the ground as a reaction force anchor for pile press-fitting and pulling out, and The present invention relates to a pile press-in and pull-out machine that is capable of relative movement of piles in parallel directions or more, and relative vertical movement by hydraulic drive, and includes a chuck as a component for grasping press-fit and pull-out piles.

Such pile press-in and pull-out machines are conventionally known, and when pressing in and pulling out piles, by gripping the existing pile with a clamp, the earth can be used as a reaction force against the pile press-in and pull-out through the pile, and it can generate an extremely large reaction force. By combining the relative vertical movement between the clamp and the chuck as well as the relative movement in the parallel direction of the piles, the pile can be press-fitted onto the pile parallel structure that has been built, and the puller can be used to create a new pile. It can be moved by itself in the required direction for subsequent press-in or pull-out construction, and pile press-in and pull-out construction in water areas such as rivers and ports can be easily performed without the need for scaffolding such as stages or built islands.

However, in conventional pile press-fitting and pulling machines of this type, in order to guide the vertical movement required for the clamp and chuck, a swivel table is mounted on a slide base that is mounted on a saddle with a clamp and can move in the parallel direction of the pile. A mast with a fixed guide rail extending vertically is mounted on this, and a sliding shoe is provided on the elevating body of the chuck that grips the press-fitted and pulled-out pile, and this is fitted onto the guide rail on the mast. In addition to relying on the guide structure formed by The height of the machine cannot be made very low, and even the lowest model has a pressing force of 60 tons, a regular pulling force of 60 tons, a maximum of 80 tons, and a chuck stroke of 50 tons.
In the case of pile press-fitting and pulling machines with specifications of cm,
The maximum height was about 2.2m.

SUMMARY OF THE INVENTION An object of the present invention is to provide a pile press-in and pull-out machine of the type described above whose height can be considerably reduced compared to conventional machines.

The pile press-in and pull-out machine of the present invention includes a saddle equipped with a clamp for grasping the piles built parallel to the ground, and mounted on the saddle and between the saddle and the piles in the parallel direction (left and right in Figs. 1 and 4). A vertical feeder capable of relative movement of more than a parallel pitch of piles in a direction (direction), a cross feeder mounted on the vertical feeder and capable of moving or rotating in a straight line in a direction across the vertical feeder, and a cross feeder mounted on the cross feeder. an elevating body that can move up and down relative to the horizontal feed board, vertical feed board, and saddle combination body by hydraulic drive; A sliding guide groove extending in the vertical direction is provided on the cross-feeding board, and the lifting body is fitted in the sliding guide groove and the lifting body is lowered. A sliding bar located below the upper end of the transverse feeder is fixed in this state, and a hydraulic cylinder/plunger device for causing relative vertical movement of the elevating object is arranged below the elevating object. It is said that

According to the present invention, a hydraulically driven relative vertical movement between a saddle provided with a clamp, a vertical feeder on the saddle, a cross feeder combination on the vertical feeder, and an elevating body is required for the chuck. The pile press-in and pull-out operations are achieved, and this relative vertical movement and vertical feed machine,
A combination of relative movement in the pile parallel direction between the cross-feeding machine and elevating body combination and the saddle, which is required for subsequent press-in or pulling of new piles. will be able to move on their own.

The guide necessary for the above-mentioned relative vertical movement is a sliding guide groove formed on the traversing board, and the sliding guide groove is fitted into the sliding guide groove and fixed to the elevating body, and the elevating body is moved horizontally when it is lowered. A sliding bar located below the top of the board performs this, and the relative vertical movement is performed by a hydraulic cylinder plunger device located below the lift.

That is, according to the present invention, the vertical movement guide structure and the vertical drive mechanism for the lifting body of the chuck, that is, the hydraulic cylinder.
The plunger device is configured to be substantially submerged relative to the lifting body, and the pile is press-fitted and pulled out. The height can be kept within the vertical dimensions of the clamp, saddle, vertical feeder, and horizontal feeder combination, and specifically, if the specifications are the same as the press force, pullout force, and chuck stroke listed above, The height can be reduced by approximately 1.1m. This dimension is 1/2 the height of the conventional model. The fact that the present invention has been able to reduce the height in this way means that as long as the pile is shortened to an appropriate length, it can be used under low overpasses, under bridges, under power transmission cables, under telephone cables, etc., which could not be done with conventional machines. This means that it is possible to press in and pull out piles.

In the present invention, the chuck elevating body is mounted on the horizontal feed board that can move linearly or turn in the direction across the vertical feed board. This is to enable centering during construction of press-fitted piles.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a clamp that grips parallel piles (not shown) on the ground, 2 is a saddle with the clamp 1 at its lower end, and 3 is a vertical feeder mounted on the saddle 2. is a hydraulic cylinder whose one end is connected to this and the other end is connected to the saddle 2.
A plunger device (not shown) allows relative movement between the saddle 2 and the parallel pile in the parallel direction over the parallel pitch of the pile.

A transverse feed plate 5 is mounted on the vertical feed plate 3, which is movable in the transverse direction by a hydraulic cylinder plunger device 4, and an elevating body 6 is mounted on the transverse feed plate 5 so as to be parallel to the desired side of the transverse feed plate 5. mount it. The hydraulic cylinder plunger device 4 is connected at one end to the vertical feed plate 3 and at the other end to the transverse feed plate 5. The horizontal feed plate 5 may be replaced with a type that can rotate horizontally on the vertical feed plate 3. In that case, the swivel of the cross-feeding machine is carried out using conventional swiveling mast-mounted pile press-fitting,
This may be done using a device similar to the mast rotation device in a drawing machine.
