Description

A kind of pile follower device

Technical field

The utility model relates to the underwater pile driving field, the pile follower device when particularly relating to a kind of piling strtucture thing underwater pile driving.

Background technology

At present, when building pier, at first to carry out the process of piling strtucture thing underwater pile driving, and the piling process at first will be inserted the slotting point of a pile follower device stake top, impact the pile follower device by pile hammer then and power is passed to the stake that to beat, this shows that the pile follower device is auxiliary piling to the projected depth necessary tool; Yet, present pile follower device pile follower main body with insert point for being welded to connect, its shortcoming is that weld is easy to generate fatigue and even fracture, this adverse consequences such as construction period even damage works that can occasion a delay the impacting in the process of pile hammer.

The innovation and creation content

The purpose of this utility model provides a kind of pile follower device simple in structure, with low cost, reusable.

For achieving the above object, the utility model is taked technical scheme: a kind of pile follower device, and it includes: a pile follower main body, it is the cylindric of hollow, and described pile follower main body is symmetrically arranged with two through holes near the side-walls of lower surface; One pile follower is inserted point, and its top is the cylindric of hollow, and lower cylindrical shape external surface contracts in gradually; The side-walls that described pile follower is inserted the close upper surface, top of point is symmetrically arranged with two perforation; Pile follower is inserted the internal diameter that sharp external diameter is slightly less than described pile follower main body; A connection piece, it passes two through holes of described pile follower main body and two perforation that pile follower is inserted point, and pile follower main body and the slotting point of pile follower are linked together.

In practical operation, described connector can be a pipe, and described pipe two ends respectively are provided with at least 2 limiting plate muscle sheet respectively.In order to cooperate described connector, described through hole and perforation all can be circular hole or elliptical aperture.

In addition, described pile follower main body is symmetrically arranged with two clasps near the lateral wall place of lower surface, and the angular separation of the direction of described two clasps and described two through holes is 90 degree.Described pile follower main body is symmetrically arranged with two suspension ring near the inside wall place of upper surface.

In above-mentioned pile follower device, the material that described pile follower main body, pile follower are inserted point and connector is steel.

The utility model is owing to take above design, and it has the following advantages: the tolerance that allows when 1, the utility model is made is big, and therefore making is simple, saves cost.2, because the utility model does not have the weld seam of vertical direction, therefore in piling, can avoid producing fatigue even weld cracking.3, the utility model is when pile follower is inserted the point damage, and the slotting point that more renews is very simple and convenient, and the utility model can be reused.4, the utility model also has advantages such as simple in structure, with low cost, is convenient to promote and use.

The specific embodiment

As shown in Figure 1 and Figure 2, be a kind of pile follower device provided by the utility model, it includes: a pile follower main body 1, and it is the cylindric of hollow, and pile follower main body 1 is symmetrically arranged with two through holes 11 near the side-walls of lower surface; One pile follower is inserted point 2, and its top 21 is the cylindric of hollow, and bottom 22 cylindrical outer surface contract in gradually; The side-walls that pile follower is inserted the close upper surface, top of point 2 is symmetrically arranged with two perforation 23; The external diameter of the slotting point 2 of pile follower is slightly less than the internal diameter of pile follower main body 1, can guarantee just that specifically pile follower is inserted point 2 is inserted into pile follower main body 1 the inside; A connection piece 3, it passes two through holes 21 of pile follower main body 1 and two perforation 23 that pile follower is inserted point 2, and pile follower main body 1 and the slotting point 2 of pile follower are linked together.

In the present embodiment, connector 3 is a pipe 31, pipe 31 two ends respectively are provided with at least 2 limiting plate muscle sheet 32 respectively, the concrete quantity of limiting plate muscle sheet 32 is 4 in the present embodiment, certainly, the quantity of the structural style of connector 3 and limiting plate muscle sheet 32 can change according to actual needs.According to the use needs difference of different occasions, through hole 21 and perforation 23 all can be circular hole or elliptical aperture, and through hole 21 and perforation 23 are elliptical aperture in the present embodiment, and the tolerance of its permission is bigger like this, are convenient to install and processing.

In addition, pile follower main body 1 is symmetrically arranged with two clasps 12 near the lateral wall place of lower surface, and for the position of the position discord through hole 11 that guarantees clasp 12 overlaps, therefore the angular separation of the direction of two clasps 12 and two through holes 11 is 90 and spends; And pile follower main body 1 also is symmetrically arranged with two suspension ring 13 near the inside wall place of upper surface, and it mainly is the pile follower main body that is used for slinging when point is inserted in dismounting.

In the foregoing description, the material that pile follower main body 1, pile follower are inserted point 2 and connector 3 is steel, and it preferably all is and the identical steel of piling bar material that will beat.

The utility model when in use, cooperate Fig. 3, shown in Figure 4, at first pile hammer is installed in the top of pile follower main body, and uses rope that two clasps at pile hammer and pile follower main body lateral wall place are coupled together, just can to drive the pile follower main body in mobile process mobile together for pile hammer like this; By mobile pile hammer, thereby drive pile follower main body and slotting sharp the moving of pile follower, and make the slotting point of pile follower be inserted into the stake top that to beat; Pile hammer impacts pile follower then, and the power that pile hammer impacts passes to the pile follower main body, and then power is passed to the stake that will beat by the pile follower main body.

The utility model is owing to adopt pile follower main body 1 combination pile follower to insert point knot 2 structure modes, therefore when slotting point 2 damages of pile follower need to change, only need to use gas welding to cut away the limiting plate muscle sheet 32 of pipe 31 1 ends, extract pipe 31 then out, change a new pile follower and insert point 2, plug pipe 31 then and weld upper limit plate muscle sheet 32 again and get final product.Simple to operation, and saved steel, the utility model can be reused.In addition, limiting plate muscle sheet 32 is only to need to weld together with pipe 31 to get final product in the requirement in when welding, do not need lateral wall welding with pile follower main body 1, pipe 31 can rotate like this, even move radially along pipe 31, and limiting plate muscle sheet 32 just limits pipe 31, and it can not be moved vertically, thereby the slotting point knot 2 of pile follower main body 1 and pile follower links together.
