Hydraulic pile head breaker

Technical field

The utility model relate to the stake remove especially a kind of hydraulic pile head breaker.

Background technology

We know, in the coastal and bad area of soil property, when the ground top of building weakness, when supporting capacity is not enough, adopt pile foundation.This pile foundation is the steel bar concrete pile of in-site pouring, and its end will be positioned at stratum solid under the face of land, and one section pile crown all will be retained by portion on the ground, before carrying out the superstructure construction, the concrete partial crushing of this part pile crown be fallen, and exposes reinforcing bar.The method of the broken pile crown of tradition is to cut or carry out fragmentation with pneumatic pick with manpower, and it is big to there is labour intensity, and work efficiency is low, the deficiency that noise is big.People have carried out the development of Mechanical Crushing pile crown for this reason.As in the CN2141818Y China utility model patent manual of notice of authorization on September 8th, 1993, disclosing the technical scheme of a kind of " hydraulic pile head crushing engine ", it is made up of pedestal, hydraulic jack and the crushing head in pile crown hole central authorities, oil cylinder with piston rod relatively, be installed in the periphery in pedestal central authorities pile crown hole by the center symmetry, crushing head is installed in the piston rod top, be connected with pipeline between oil cylinder, constitute the hydraulic pile head crushing engine.It is with the hydraulic pressure broken steel concrete pile crown of having an effect, and has that labor strength is low, a noiselessness, advantage that work efficiency is high.Because its crushing head is short and small cutter head, guarantee good crushing effect, a plurality of crushing heads are set, and crushing head is to be directly installed on the piston rod top, thereby the quantity that is provided with of oil cylinder is increased, exist the high deficiency of manufacturing cost.

Summary of the invention

In order to overcome the high deficiency of hydraulic pile head crushing engine manufacturing cost in the prior art, the utility model provides a kind of hydraulic pile head breaker, and this hydraulic pile head breaker is not only rational in infrastructure, low cost of manufacture, and easy and simple to handle, reliable operation, noiselessness, the work efficiency height.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic pile head breaker, it is by the pedestal that has the pile crown hole, hydraulic jack and crushing head are formed, it is characterized in that: on the pedestal of described pile crown hole periphery, be fixedly connected with supporter, described hydraulic jack is hinged on the outer top of this supporter by its cylinder body symmetry, described crushing head is by the connection part that is wholely set, articulated section and crushing teeth are formed, this crushing head is corresponding with hydraulic jack to be hinged on bottom outside the supporter through its articulated section, the piston rod of hydraulic jack and the connection part of this crushing head are hinged, the crushing teeth of crushing head is positioned at the bottom symmetric arrangement of supporter, correspondence between the hydraulic jack is supplied with oil circuit and is controlled its connection by an oil circuit distributing valve, and the piston rod of each hydraulic jack is stretched, contract synchronously.

Described on the peripheral base of pile crown hole fixedly connected supporter, its inside wall pieces together a fairlead, this fairlead cross sectional shape is consistent with the pile crown hole shape, and the crushing head crushing teeth that described symmetry is positioned at the supporter bottom is that symmetry is positioned at the entrance, fairlead lower end that the supporter inside wall is put together.

The described hydraulic jack that is hinged on supporter top through its cylinder body symmetry is a symmetric arrangement in twos.

The utility model is to provide power by hydraulic jack for it, by the crushing head that is hinged with hydraulic jack to the pile crown attrition crushing.Compared to existing technology, it is safe and reliable, and noiselessness is easy and simple to handle, and labour intensity is low, the work efficiency height.

The specific embodiment

In Fig. 1, a kind of hydraulic pile head breaker is made up of pedestal 1,

hydraulic jack

2 and 3 three main members of crushing head.

As shown in Figure 1, pedestal 1 can adopt forms such as monoblock cast, sheet material cutting forming or combine and assemble to constitute.The preferential metal sheet cutting forming that adopts of present embodiment.

In Fig. 1, it has pile crown hole 4 at central part.Pile crown hole 4 is to be enclosed within to treat broken pile crown part, and it looks the shape of reinforced concrete pile, and pile crown hole 4 can be circle, square or other shape.The square structure that present embodiment adopts.

In Fig. 1, Fig. 2, Fig. 4, on the pedestal 1 of pile crown hole 4 peripheries, be welded with supporter 5.Supporter 5 can be that the metal sheet seam forms, and also can be to be combined by forging.For overall construction intensity and the rigidity of strengthening supporter 5, what present embodiment adopted is that forging combines.Simultaneously, put the convenience for the treatment of broken pile crown and the accuracy that improves broken pile crown in order to overlap, as Fig. 1, Fig. 3, shown in Figure 4, the inside wall of supporter 5 pieces together a fairlead 6, these fairlead 6 cross sectional shapes are consistent with pile crown hole 4 shapes, be that fairlead 6 cross sectional shapes are square, the inside wall of its supporter 5 is symmetrical in twos.

In Fig. 1, Fig. 2, Fig. 4, the cylinder body 201 of hydraulic jack 2 is hinged on supporter 5 outer tops by bearing pin 7 symmetries.Hydraulic jack 2 is power supplying apparatus of hydraulic pile head breaker, and its quantity and the arranged mode on supporter 5 will be decided by the situation for the treatment of broken pile crown.Present embodiment is even in order to guarantee pile head breaking, avoids pile breaking phenomenon, and hydraulic jack 2 is 4, is to be in twos that symmetrical manner is arranged in supporter 5 outer tops.

Crushing head 3 is direct force application components of hydraulic pile head breaker.In order to guarantee that it has sufficient intensity and reliable service behaviour, as shown in Figure 4, crushing teeth 3 is made up of the connection part 301 that is wholely set, articulated section 302 and crushing teeth 303.

In Fig. 2, Fig. 4, crushing head 3 is corresponding with hydraulic jack 2, is similarly 4, and it is hinged on bottom outside the supporter 5 through its articulated section 302 respectively, and the piston rod 202 of hydraulic jack 2 is hinged by hinge 8 with the connection part 301 of crushing head 3.The increment of crushing teeth 303 is a wedge structure, and is positioned at the bottom symmetric arrangement of supporter 5.Because supporter 5 inside walls are fairleads 6 that are put together, therefore, as shown in Figure 3, Figure 4, the crushing teeth 303 of crushing head 3 is symmetrical in twos entrance that are positioned at fairlead 6.

Fig. 5 has provided oil circuit control chart of the present utility model.4 hydraulic jacks 1 of the present utility model are and an oil pump station 11 adapteds, provide hydraulic coupling and control by pumping plant, realize the attrition crushing to pile crown.As shown in Figure 5, correspondence between each hydraulic jack 1 is supplied with oil circuit 901,902 being communicated with by an oil circuit distributing valve 10 unified controls and pumping plant 11, with the synchronism of piston rod on stretching, contracting that guarantees each hydraulic jack, thus the pressure that makes crushing teeth apply uniformly, equate to pile crown.

The utility model provides power by oil pump station for hydraulic jack, drives the broken of crushing head by its piston rod The mode that broken tooth splits and then crushes with nib around the pile crown, the efficiency crushing pile crown, it has work Safe and reliable, noiselessness, easy and simple to handle, labour intensity is low, the advantage that work efficiency is high.
